Introduction
Ethnic minorities have formed a unique cultural system in the long history and radiate their own unique attraction and unique style. One of the important strategies for developing a cultural tourism platform is to display the most representative and characteristic culture of ethnic minorities through the platform, to dig deep into the cultural customs, and to let tourists appreciate the beauty of ethnic minorities.
In the context of the rapid advancement of information technology and the upsurge of smart city construction, this study sorts out the current situation and problems of ethnic minority tourism information service systems, analyzes tourists' evaluation and demand for ethnic minority tourism information services, and provides new ideas for the transformation and upgrading of tourism cities. It also lists some domestic cities as typical cases, analyzes the construction practices of ethnic minority tourism information service systems in the process of smart city construction, finds out the shortcomings, and gives countermeasures and suggestions. It has important theoretical exploration and practical guidance value. e development of global tourism puts forward new requirements for the construction of smart tourism. Mohamad M believes that more and more tourism-related data have reached the level of TB or even PB, which brings great difficulties to tourism management. His research is not innovative [1]. Nenkov identified the requirements for human resource development. At the same time, according to the economic methodology that describes human resource development as a circular process, an appropriate human resource development management system is determined. His research lacks data [2]. Cheng believes that recently, TODIM, which can represent the psychological behavior of decision makers under risk, has been introduced to deal with the multiattribute decision-making (MADM) problem. In addition, the binary language term set is an effective tool to describe the uncertainty of MADM problems. He extends the TODIM method to MADM with 2meta language information. He begins with a brief introduction to the definition and distance of binary language information and walks through the steps of the classic TODIM method to solve the MADM problem. en, based on the classical TODIM method, he proposed an extended TODIM method to deal with the MADM problem of attribute values in binary language information, so his research is not sufficient [3]. Wei proposed the overall design of industrial information service platform based on tourism big data. His research focuses on the overall function, data source, data standard, and application scope of the platform [4]. Ashari believes that one of the biggest attractions of Bandung's tourism industry is nature tourism. Restrictions on obtaining information about Bandung's nature tourism still exist, as there are new attractions in Bandung every year.
is is especially true for foreign tourists outside of Bandung. Tourists are still confused about finding new and popular tourist attractions, and these places are worth visiting. He did not further explore the economic value of tourism [5,6]. Filda believes that tourism loyalty is created through the good quality of tourism services and the availability of tourism products. His research discusses various attributes of tourism service quality, namely travel agents, efficient people, accessible transportation, and information service quality. Except for the impact of tourism service quality on the loyalty of Indonesian tourists, other assumptions in his research are inconclusive [7]. Setiorini studies and analyzes the grammatical errors in the spoken English of customer service in Malang Tourism Information Center. e purpose of his research was to determine what types of errors customer service said were made and why. ese data were collected from four customer service offices by recording their conversations with tourists, and his research data were too small [8].
is research mainly discusses the design of ethnic minority tourism information services and sustainable tourism development in the context of smart cities. e smart tourism public service application system must meet the three major requirements of different service objects. One is a smart service system aimed at satisfying tourists' travel information services. e second is to meet the needs of tourism companies for online marketing and e-commerce on the platform. e third is to provide a platform for the government to master travel information and supervise the travel market to realize e-government management. erefore, the smart tourism application system includes three aspects: service, market, and management. Smart cities are built on the basis of digital  cities, inheriting IBM's wisdom concept, and use advanced  information technology to enable citizens, enterprises,  governments, and institutions to communicate and operate  more conveniently and efficiently. e intelligent city construction basically complies with a certain pattern, combining the advantages of the city's own current situation and long-term development plan and the building of three systems from the bottom up: the basic and intermediate exchange layers, and the middle and upper application layers. is will change the traditional outward operating service mode of various roles so that we can realize the intelligence of life, life production, and life managing.

Smart City.
Because the information has the characteristics of comprehensiveness, timeliness, systematicness, relevance, accessibility, and accuracy, the ability and level of tourism information service not only affect the overall marketing effect of a tourism destination but also related to the quality of its tourism reception service. Finally, it affects the shaping of tourism destination image and the overall development of tourism. e evaluation index of accessibility is [9,10] R � n i�1 T n . (1) Among them, i stands for tourist attractions and T stands for a certain point in the area. e calculation formula of vegetation coverage in tourist area is [11] f � Among them, f represents the vegetation coverage rate. e biological abundance index calculated according to the relevant weights is [12] S z � A ×(0.35f + 0.21g + 0.11c + 0.04b + 0.01u), (3) where S z stands for biological abundance index. e degree of disturbance of human activities to the landscape can also be used to characterize the fragmentation of the landscape at a specific time and nature PH [13].
Among them, t represents the comprehensive comfort index. e calculation method of ecological footprint is [15] E � NF � N n i�1 ra.
Among them, NF represents the total ecological footprint. Ecological carrying capacity represents its ability to update people's needs [16]. 2 Mobile Information Systems e ecological deficit of scenic spots reflects the difference between the ecological carrying capacity and ecological footprint of a region or country [17].
For the tourist ecological footprint [18]: Among them, EF T and ef, respectively, represent the total tourist ecological footprint and total ecological footprint of the area. e ratio between the two variables is expressed as follows [19]:

(3) e latest activity guide: the latest activity guide mainly relies on the database server of each scenic spot in the system background. A large number of tourist scenic spots at home and abroad are collected in the database, such as scenic spot address, scenic spot introduction, and real-time latest activity guide of scenic spot. Users can independently choose the scenic spots they want to know and click to get the latest activity information provided by the platform. (4) Unified notification service: the unified notification service is a reminder and notification service that the platform provides to users. When users conduct information interaction services such as user registration, online reservations, and online transactions on the platform, the platform provides SMS notification services and e-mail notification services. e notification service is sent to users in SMS or HTML encoding, and users can obtain information directly through SMS or click a link. It allows visitors to send platform registration and trading information via SMS or e-mail to enable online platform user for registration and order management via SMS as well as e-mail. is service includes SMS verification code, registration feedback information notification service, notifications for order management include online order code, and order details and other monitoring information in marketing. e scenic spot information is shown in Table 1.

Smart Tour Guide Subsystem.
e smart tour guide subsystem provided by the Minority Smart Tourism Service Platform is a system supported by mobile terminal devices. It can provide self-service tour guides, guided tours, and navigation services based on various geographic information data provided by the geographic information system (GIS). e system obtains the GPS positioning signal of the satellite through the user's mobile terminal equipment and sends the position information to the GIS system through data transmission. Because the GIS system can realize map browsing, dynamic query, and basic map operations, it provides modern technical support for navigation, tour guide, and navigation. e main functions of the intelligent tour guide subsystem are as follows: (1) Online navigation service: the online navigation system is connected to the network in real time. e entire map data storage and path planning are completed on the platform server. rough data transmission, online navigation map information and route recommendations are finally formed on the user terminal. e online navigation service supports target location setting and navigation route calculation and display, and GPS service is required to provide the user's location data as the initial location. Online navigation services support map display, route planning, and geographic location search engines.
(2) Self-guided tour guide service: users can log in to the platform and click on the self-service tour guide service. e system will automatically obtain user geographic information from the user's mobile phone and automatically play tour guide audio and video data based on this. is function is technically supported by the GPS positioning system, and the guide information database is the data base (including guide audio data, historical introduction information of scenic spots, cultural information of scenic spots, etc.) to provide tourists with real-time guide services.
(3) Automatic guided tour service: an automated tour guide service also relies as well on GPS positioning technology, which is combined with 3D virtual technology. rough the acquisition of the user's geographic information, it can accurately locate and perceive the tourist attractions and explain the attractions actively before the tourists, providing a 3D virtual tour service for the display of real scenes and tourist guidance information for the visitors. e automatic navigation service is shown in Figure 2.

Interactive Communication Subplatform.
e Minority Smart Tourism Service Platform is to facilitate communication between tourists and provide a platform for asking questions and answering doubts. e platform has two main functions, namely: (1) Travel Q&A: travel Q&A is an online question answering section set up by the interactive communication platform. Tourists can submit their questions during their travels by clicking on the "Travel Q&A" section. e platform can provide a standard question publishing format, and visitors upload their own questions by filling in the questions. is section will have dedicated service personnel to collect and feedback questions, support real-time or next-day reply, and support the push and online display of reply information. (2) Interactive forum: the interactive forum is an exchange platform for visitors to display travel notes sharing, photography sharing, and online interaction.

rough online communication, tourists can make like-minded friends, share travel insights, and even broaden the resources of tourist destinations. 6 Mobile Information Systems

Tourist Complaint Service Subplatform.
e construction of the tourism complaint service subplatform allows tourists to complain about dissatisfaction with scenic spots and tourism activities during and after traveling through various user terminals and to track complaints handling. e tourist complaint service platform also provides customer service complaints, 12,301 complaint hotline, national smart tourism public service WeChat official account, and other complaint methods. It is up to the user to choose the complaint channel that he or she thinks is convenient.

Module Composition.
With the building of smart tourism management application module, we have provided basic guarantee for real-time data update and response for the intelligent tourism service platform of minority groups, which enables the analysis and sharing of information data of as a whole tourism industry, contributes to the strengthening of tourism property alliance, and improves the regulatory ability of provincial government offices. e system module includes an information collection and release system, an information integration analysis platform, and an emergency response system. e information of tourism management department is shown in Table 2.

Functional Design
(1) Tourism information collection and release module: an important application system that the platform management department has for information management of the minority intelligent tourism service platform is the information collection and release module. rough the interfacing with other third-party systems such as video monitoring, as well as environmental monitoring and emergency respond platform, the system collects real-time information and extracts real-time information such as visitor flow, client data, environmental information, scenic area-related information on unexpected events, and real-time information on national tourism in policy. And through the information release system to release dynamic travel information to various user terminals (websites, mobile phones, media screens, etc.). Figure 3 shows the collection and release of tourism information. (2) Integrated video supervision module of scenic spots: the minority smart tourism service platform must be connected with the establishment of a comprehensive video supervision system for scenic spots and provide real-time retrieval and viewing functions of all scenic spots videos, so that managers can directly supervise the safety of scenic spots through the platform and implement corresponding safety prompts. e surveillance range of the scenic spot video surveillance system must cover the scenic traffic arteries, scenic entrances and exits, key protected areas and areas with high accidents, and support long-term surveillance data storage. e establishment of the scenic spot video supervision system can make the work management more scientific, precise, intelligent, and informatized and can enable managers to intuitively manage various affairs in each scenic spot through the platform. e scenic video integrated supervision system is connected to the internal platforms of each scenic spot through the TCP/IP protocol, so that the system can obtain the resources of each subsystem through system connection and data exchange and can perform realtime management operations [24,25].
(3) System analysis subplatform: the statistical analysis platform includes system traffic statistics, system investigation, and analysis. rough the collection, analysis, sorting, and sharing of user access data, tourism companies can provide targeted and personalized service construction and make tourism services smarter and more scientific. Among them, the system traffic statistics system is based on the platform visits, statistical analysis of visiting IP addresses, search keywords, and clicks on functional applications, to determine the influence of the platform and the attention of visitors. e focus and the preference of visitors can be used for tourism companies and tourism. Platform managers provide databases. e platform can automatically establish data management, store data according to information classification, support the automatic generation of various charts, and realize the analysis of user preferences [26].   Table 3.
e ability and quality of service personnel in the scenic area are also factors that may cause security risks in the scenic area. e service attitude, service skills, and level of the service personnel in the scenic area directly or indirectly affect the safety of tourists. A large part of the sanitary problems experienced by tourists in the travel process such as accommodation and catering are due to deviations in the service skills of service personnel. Compared with the professional service personnel, their service awareness and safety awareness are not very strong. e ability and quality of service personnel have a certain relationship with the degree of education they receive. e ability and quality of personnel with relatively high education level are relatively high. e statistics of service personnel in the scenic area are shown in Table 4.
Smart tourist attractions have not been established in my country for a long time, and they have not accumulated enough experience. erefore, it is necessary to rely on relevant experts in the tourism field to compare the importance of primary risk factors and secondary risk factors to the total risk factors. e discriminant matrix is shown in Table 5.
Based on the investigation and analysis of ethnic minority foreign tourists, combined with the data analysis results of the online questionnaire survey, 172 questionnaires were distributed online, 164 were retrieved, and 161 valid questionnaires were collected. e male to female ratio of the target user population is 54.55% for girls and 45.45% for boys. e research and analysis ratio is shown in Figure 4.
As shown in Figure 5, freelance and students account for a larger proportion of tourist occupations, and other occupations also account for a large proportion. Freelance entrepreneurs have irregular working hours and are relatively free in travel time. Students have regular winter and summer vacations every year, and relatively speaking, they have ample travel time, which creates good conditions for travel. e occupation of tourists is shown in Figure 5.
e target user population of tourism is mainly young people and above, and the age range is mainly from 19 to 40 years old. e age distribution of tourist target users is shown in Figure 6.
In In the survey results, 39.09% of tourists are interested in ethnic minority food, and some tourists are interested in ethnic minority buildings and costumes and intangible cultural heritage. ese indicate from the side that intangible cultural heritage has left a place in the hearts of tourists. Tourists' preferences for ethnic minorities are shown in Figure 8. e tourism platform design login and registration interface background adopt ethnic blue as the background color and make full use of the shading to create a national atmosphere, strengthen its cultural immersion, and let users feel the charm of ethnic minorities in the process of logging in and registering. e font color adopts white and blue to form a strong contrast with the background, focusing on the text information. e eye-catching logo at the top of the interface echoes with the content of the APP design and fully demonstrates the design theme of the ethnic cultural tourism platform, as shown in Figure 9.
According to the data, the tourist destinations of residents in M City have undergone tremendous changes from 2011 to 2018. Beginning in 2011, the number of people in M City who use leisure and vacation as their tourism purpose has continued to increase. After 2016, there was a huge increase, accounting for 50.1% of the total number of people, and it dropped slightly to 48.3% in 2018. From the data of City M alone, the city's total tourism revenue in 2020 will reach 75.68 billion yuan, a year-on-year increase of 21.33%, of which foreign exchange income is US$886 million, a yearon-year increase of 33.56%. e sustainable development of the tourism industry provides a good economic environment for the construction of smart tourism. Coupled with government subsidies, infrastructure construction is easy to  complete. It can also complete the upload of information and data, but most small-scale tourism, especially with the development of rural revitalization, various pastoral complexes, ancient villages are small in scale, and the tourism business is relatively single. It is difficult to complete the integration of technology and industry. Smart tourism applications are aimless, software cannot be connected to the platform, and it is difficult to form data analysis after being connected to the platform in time and provide constructive data for later construction. e income of City M is shown in Figure 10.

Discussion
e ethnic minorities have a gathering of humanities, and the development of ethnic minority culture has become more and more mature in the long years. At present, the culture of ethnic minorities is gradually disappearing and sinicized. Many intangible cultural heritages are on the verge of uninherited and unknown crisis. It is urgent to strengthen the public's awareness of ethnic minority cultures [27].
If the economic benefits brought by the implementation of the smart tourism system can be greater than the development cost of the system, it is feasible. e construction cost of the smart tourism system includes the purchase of hardware and software systems, geographic information systems (GIS), personnel costs, and publicity costs. According to the scale of the construction of the smart tourism system, the cost is between several million yuan and ten million yuan. Although the system investment is high, the investment in the smart tourism system is worthwhile from a sustainable perspective. After the completion of the smart tourism construction, it will bring the following benefits: publicize tourism, increase passenger flow, make full use of the resources of the tourism province, and drive the economy development; increase the income of other subsidiary industries, and the increase in passenger flow will inevitably drive the income of a series of subsidiary industries; the reduction of personnel costs, the use of smart tourism information systems can not only improve the passenger experience but also reduce the cost of personnel in the tourism industry. erefore, in the long run, the smart tourism information system is sustainable in terms of economic benefits [28]. Smart tourism information system should not be designed only for tourists. Smart tourism is a combination of cloud computing, Internet of ings, mobile communication technology, and artificial intelligence technology. It is important for tourists to display information, but at the same time, the collection and processing of information are equally important. It can add fresh blood to the smart tourism information system, maintain the real-time, accuracy, and sustainability of the information of the smart tourism information system, so as to better serve tourists and further promote the sustainable development of the tourism industry. e design of a smart tourism information system should not only be aimed at        tourists. Tourism management departments, scenic spots, tourism companies, hotels, etc. should all participate in information interaction, management, or commercial competition. is is bound to have a positive effect on the sustainable development of smart tourism. e role of promotion also has a certain effect on the sustainable development of smart cities. At the same time, the medium of information collection and display of the smart tourism information system should not be limited to mobile devices. Combining personal PCs, smart tourism WEB website construction, scenic spot multimedia query systems, scenic spot LED query systems, telephone queries, short message services, etc., can promote diversified development of urban smart tourism that facilitates the participation of tourists and smart tourism-related departments or personnel and ultimately attracts more tourists with its convenience and promotes the sustainable development of tourism [29].
