[0001] The present invention relates to the technical field of urban management systems, and in particular to an urban management system based on smart supervision services. Background Art

[0002] With the rapid development of the national economy, urban development has shown the characteristics of networking, digitization, informatization and intelligence. Especially in recent years, information resources have increasingly become an important part of the urban resource system and an urban production factor, and their leading and supporting role in economic and social development has become more apparent. Against this background, some countries, regions and cities have taken the lead in proposing the development strategy of building smart cities. Smart cities are to endow various resource elements of cities through advanced information technology, generate a large amount of information resources, promote the construction and integration of urban information resource systems, and achieve efficient, convenient and innovative coordination of urban management and operation.

[0003] In real life, the issues that people need to report are mostly the same. However, the traditional urban management system is unable to directly respond to people based on previous issues, resulting in repeated questions and greatly delaying service work.

[0004] Therefore, the inventors in this field proposed an urban management system based on smart supervision services, which uses a problem retrieval unit to classify problems, match historical cases, and perform similarity analysis to help owners accurately describe problems and provide previous solutions. This mechanism not only improves the accuracy of problem description, but also speeds up problem handling, thereby solving the above-mentioned problems. Summary of the invention

[0014] In a possible implementation, the question retrieval unit b is consistent with the subunit of the question retrieval unit a, the difference is that the question retrieval unit a serves the owner, and the question retrieval unit b serves the property. The question retrieval unit a and the question retrieval unit b are matched with historical cases through the Jaccard similarity analysis algorithm. The Jaccard similarity is an indicator for measuring the similarity of two sets. It determines the similarity by calculating the ratio of the size of the intersection of the two sets to the size of the union. The specific formula of the Jaccard similarity algorithm is as follows: ; in, and There are two sets, Is a collection and The number of elements in the intersection of Is a collection and The number of elements in the union.

[0015] Beneficial effects compared with the prior art: 1. In this solution, the problem retrieval unit is used to classify problems, match historical cases, and perform similarity analysis to help owners accurately describe problems and provide previous solutions. This mechanism not only improves the accuracy of problem description, but also speeds up the problem handling process. Owners can quickly find similar problem handling experience through the system, thereby avoiding repeated reporting and handling of problems, reducing the workload of property and government departments. At the same time, this intelligent retrieval mechanism also provides owners with a more convenient service experience, making the problem-solving process more efficient and transparent; 2. In this solution, cases requiring government intervention are intelligently screened through a screening algorithm. This unit can identify problems with a large number of similar cases and good evaluations from owners, and automatically mark them as "non-government intervention cases", thereby effectively avoiding unnecessary waste of government resources. On the contrary, for those cases with a large number of similar problems and poor evaluations, the system screening unit will directly feedback the problem and property solution to the government platform through the government interaction unit b after receiving the government intervention request, so as to ensure that the problem is handled in a timely and effective manner. This mechanism not only improves the efficiency of government intervention, but also optimizes resource allocation, ensuring that the resolution of owners' problems is more accurate and efficient.

[0016] 3. In this plan, a legal solution is provided for urban management through the government intervention mechanism. When the owner is dissatisfied with the property handling results, the government platform can intervene, which ensures the legality and compliance of problem handling. The government platform can classify problems according to the type of problems and forward them to relevant functional departments. These departments analyze the problems based on policies, laws, etc. to ensure the fairness and rationality of the handling process. This mechanism not only protects the legitimate rights and interests of the owners, but also improves the transparency and credibility of problem handling. In addition, the relevant functional departments supervise the property behavior to ensure that property service companies comply with laws and regulations, improve the level of property services, and ensure that the interests of owners are protected.

Problem release unit: Owners can select the problem type (such as property service supervision, water, electricity, gas, protection of the rights and interests of the community’s public areas, etc.) through the APP, describe the problem in detail, and upload evidence (pictures or videos); 1.2. Problem retrieval unit a: The system provides a search function for similar problems to help owners quickly find possible solutions or experience in dealing with similar problems; The question retrieval unit a matches the historical cases through the Jaccard similarity analysis algorithm. The Jaccard similarity is an indicator for measuring the similarity between two sets. It determines the similarity by calculating the ratio of the size of the intersection of the two sets to the size of the union. The specific formula of the Jaccard similarity algorithm is as follows: ; in, and There are two sets, Is a collection and The number of elements in the intersection of Is a collection and The number of elements in the union; The question retrieval unit a includes: 1.2.1 Problem Classification Subunit: Preliminary classification of problems posted by owners to quickly identify the nature and urgency of the problems; 1.2.2 Historical Case Matching Subunit: Match the owner's problem with similar problems in the historical case library to provide the owner with reference; 1.2.3 Similarity Analysis Subunit: Analyze the similarity between the owner's problem and historical cases to determine the uniqueness of the problem and the difficulty of handling it; 1.2.4 Solution recommendation subunit: based on the similarity analysis results, recommend solutions to similar problems for owners; 1.3 Result feedback unit: Owners can view the problem handling results and related certification documents on the APP; 1.4 Evaluation and feedback unit: Owners can evaluate their satisfaction with the results of problem handling, and the evaluation results are used to improve service quality; 1.5 Government Affairs Interaction Unit a: used for government affairs feedback, allowing functional departments to participate in the problem handling process, and exchanging data with the City Service Management Center to facilitate information transmission between functional departments; 2. Property management platform module: As the main interface for the property to interact with the system, it allows the property to view the problems posted by the owners and the solutions to similar problems, so that the property can better solve the owners' problems; 2.1 Question receiving unit: used to view the questions posted by the owners and the historical case handling methods initially retrieved by the urban service management center module; The property management center will then respond to the question online or arrange for offline processing based on the type and complexity of the question; 2.2 Result feedback unit: After the property platform solves the problem, it will feedback the processing results and relevant certification documents to the urban service management center; 3. Urban service management center module: As the center of problem handling, it receives problems from owners, classifies and records them, coordinates the property management platform to handle the problems, and feeds back the handling results to the owners; 3.1 Problem collection and classification unit: Receive problems reported by owners, and make preliminary classification and records; 3.2 Question retrieval unit b: used to match the questions posted by the owners with historical cases, analyze the solutions of historical cases, and provide the property for reference; The question retrieval unit b includes: 3.2.1 Problem Classification Subunit: Preliminary classification of problems posted by owners to quickly identify the nature and urgency of the problems; 3.2.2 Historical Case Matching Subunit: Match the owner's problem with similar problems in the historical case library to provide property references; 3.2.3 Similarity Analysis Subunit: Analyze the similarity between the owner's problem and historical cases to determine the uniqueness of the problem and the difficulty of handling it; 3.2.4 Solution recommendation subunit: based on the similarity analysis results, recommend solutions to similar problems for the property; 3.3 Transmission unit: Transmits the problems reported by the owners and the retrieved solutions to the property management center for problem handling; 3.5 Result feedback unit: Feedback the results and relevant certification documents processed by the property or functional department to the owner's personal APP terminal; 3.6 System screening unit: Screening cases that require government intervention. Through the screening algorithm, for problems with many similar cases and good evaluation, the system will automatically mark them as "non-government intervention cases", and then reject the owner's request for government intervention. On the contrary, if there are many similar problems with poor evaluation, after receiving the problem that requires government intervention, the system will directly feedback the problem and the property's solution to the government platform through the government interaction unit b; The specific formula of the screening algorithm is as follows: ; For problem solving efficiency, For satisfaction, and is the weight coefficient; In addition, is the number of similar cases retrieved by the system, The threshold used to determine whether government intervention is necessary; if and A certain number of cases are marked as "non-government affairs cases". or A certain preset number of cases will require government intervention; That is, for problems with many similar cases and good evaluation, the system will automatically mark them as "non-government intervention cases" and then reject the owner's request for government intervention. On the contrary, for problems with many similar cases, with treatment results but poor evaluation, or cases with no history of similar cases and poor evaluation by owners, after receiving problems that require government intervention, the system will directly feedback the problems and the property's solutions to the government platform through the data exchange channel with the government platform; 3.7 Government Affairs Interaction Unit b: Data exchange with the City Service Management Center to facilitate information transmission between functional departments; 3.8 Case update unit: Update the owner's problems and their handling results to the historical case library for future retrieval and reference; 3.9 Data exchange unit a: receives information disclosure content from the government affairs platform and transmits it to the owner’s personal APP module for the owner to view; 4. Government Affairs Center Platform Module: Receive requests for government affairs intervention when owners are dissatisfied with the results of problem handling, classify the problems and forward them to relevant functional departments, receive the results of the functional departments and feedback them to the Urban Service Management Center, and be responsible for publishing important information and ensuring information transparency; 4.1 Government Affairs Interaction Unit c: Receives problems reported by owners through the APP, classifies them, and assigns them to relevant functional departments; The government affairs interaction unit c includes: 4.1.1 Problem analysis subunit: classify the problems transmitted by the Urban Service Management Center and match them with the corresponding functional departments; 4.1.2 Problem communication subunit: communicate the problem to the corresponding functional department; 4.1.3 Problem Feedback Subunit: Relevant functional departments upload the results of problem handling and then feedback to the Urban Service Management Center through this subunit; 4.2 Data exchange unit b: The government platform publishes the information disclosure content and transmits the information to the mobile APP personal terminal through the data exchange unit; In summary, the owner publishes the problem through the personal APP module, which is the main interface for the owner to interact with the system. The owner can select the problem type in the problem publishing unit, describe the problem in detail, and upload relevant evidence. At the same time, the problem retrieval unit a will search for similar problems in the historical case library based on the problem published by the owner, helping the owner to quickly find a solution; The questions posted by the owner are then received by the city service management center module, which is responsible for classifying and recording the questions and coordinating the property management platform to handle them. The question retrieval unit b in the city service management center module is similar to the sub-unit of the question retrieval unit a, but serves the property, helping the property to match the owner's questions with historical cases and analyze solutions; After the property management platform module receives the problem, the problem receiving unit will check the problem posted by the owner and the historical case handling methods initially retrieved by the city service management center module, and start to handle the problem. After the processing is completed, the result feedback unit will feedback the processing results and relevant certification documents to the city service management center; After receiving the processing results of the property, the Urban Service Management Center module will feed back this information to the owner's personal APP through the result feedback unit. If the owner is satisfied with the processing results, he can evaluate the satisfaction through the evaluation feedback unit. If he is not satisfied, the owner chooses government intervention. The system will first screen and provide the government interaction unit b to transmit the problem, property processing results and historical case processing methods to the government center platform module. Otherwise, if it is not suitable for government intervention, the application will be rejected and the reason for rejection will be given. After the government affairs center platform module receives the problem, the government affairs interaction unit c will classify the problem and assign it to the relevant functional departments for resolution. After the functional departments have completed the processing, the problem feedback subunit will feedback the results to the urban service management center, which will then feedback to the owner. At the same time, the data exchange unit b ensures that the information disclosure content of the government affairs platform can be transmitted to the owner's mobile APP personal terminal; Finally, the case update unit will update the owner's problem and its handling results to the historical case library for future retrieval and reference, while the data exchange unit a is responsible for receiving the information disclosure content of the government platform and transmitting it to the owner's personal APP module for the owner to view.

[0020] Please refer to Figure 3 As shown, the specific implementation method of the above-mentioned city management system based on smart supervision service includes the following steps: Step 1: Post a question 1.1 Owners post questions through the personal end of the mobile APP and select the type of question. The types of questions mainly include property service supervision, water, electricity and gas problems, and protection of rights and interests of public areas in the community; 1.2. The owner shall fill in the details of the problem to be solved, including the time, location, scope of impact, specific description of the problem and any relevant pictures or video evidence; Step 2: The owner chooses whether to search for similar issues 2.1. If you do not select search, go directly to step 2.4; 2.2. If you choose to search, the system will automatically search for similar issues based on the issues posted by the owner, and provide the owner with solutions to similar issues after the search; 2.3. The owner compares the solutions to similar problems provided by the system with his own problems. If the method can solve the owner's own problem, the owner can execute it according to the instructions of the method. If it cannot solve the problem, the owner can supplement the difference information of the current problem based on other problems involved in the problem to ensure the accuracy and uniqueness of the problem description; 2.4. After the owner confirms that the problem description is correct, he / she will publish the problem through the APP. The system will record the problem and prepare to enter the classification processing stage; The above-mentioned problem search is a keyword search performed by the system based on the type and content of the problem filled in by the owner. After retrieving similar cases, the system provides the owner with specific solutions, that is, the process and steps of others in dealing with similar problems. However, considering that the problems faced by each owner are somewhat different, the retrieved content does not include specific processing results; Step 3: Data Classification 3.1. The Urban Service Management Center receives feedback from owners and classifies them according to the type and urgency of the problem; 3.2. After the problem classification is completed, the system automatically retrieves related problem cases and analyzes the solutions to the related cases; 3.2. Deliver the classified problems and solutions to related cases to the property management platform to ensure that the problems can quickly reach the corresponding processing department; Step 4: Question Answering 4.1. After receiving the problem and solution reference, the property management center will respond online or arrange offline processing according to the type and complexity of the problem; 4.2. For issues that require offline processing, the property management center will arrange professionals to conduct on-site inspections and processing, and ensure that the processing process complies with relevant laws and regulations and standards; Step 5: Result Feedback 5.1. After the property platform solves the problem, it will feedback the results and relevant certification documents to the Urban Service Management Center; 5.2. The Urban Service Management Center will feedback the processing results and relevant certification documents to the owner’s mobile APP personal terminal; As mentioned above, after the property management company feeds back the results to the city service management center platform, the platform will classify them according to the owner's final choice. If the owner disagrees, the data content will only be retained. If the owner approves the property management company's solution, the system will automatically analyze the problem. The purpose is to search for the problem when other owners ask similar questions in the future. The system can display the solution provided by the property management company to the owner for reference. Step 6: Government feedback 6.1. The owner can check the processing results through the personal mobile APP and evaluate the satisfaction of the problem processing results. The evaluation results will be used to improve the service quality; 6.2. If the owner is satisfied with the handling result and the problem is resolved, the system will record the owner's satisfaction and serve as a reference for future service improvements; 6.3. If the owner is not satisfied with the handling result, the owner can choose whether to ask the government to intervene. If the government intervenes, the owner can directly submit the problem and doubt to the government through the personal end of the mobile phone APP. The Urban Service Management Center will determine whether to intervene through system screening; If the functional department provides a final solution later, the system will replace the property's solution so that subsequent owners can retrieve better solutions when they post similar questions. Step 7: System Screening After the owner applies for government intervention, the system automatically collects and analyzes the submitted problem, the handling method fed back by the property management, the handling results of similar problems in the past, and the evaluation of owners of similar problems in the past. Through comprehensive analysis, it determines whether the method provided by the property management can solve the owner's problem, and then determines whether government intervention should be carried out; 7.1. The system classifies and compiles statistics on the collected data, identifies the types of problems that occur frequently and the corresponding solutions; 7.2. The system conducts in-depth analysis of high-frequency problems and evaluates the efficiency of problem solving and the satisfaction of owners; 7.3. The system establishes an evaluation model for problem-solving efficiency and satisfaction. For problems with a large number of similar cases and good evaluations, the system will automatically mark them as "non-government intervention cases" and then reject the owner's request for government intervention; In summary, non-government intervention cases are mainly cases with a history, treatment results, and high evaluation of treatment results. On the contrary, there are many similar problems, with treatment results but poor evaluation, or similar cases without history and poor evaluation by owners. After receiving the problems that need government intervention, the system directly feeds back the problems and the property solutions to the government platform through the data exchange channel with the government platform; Step 8: Government Affairs Processing 8.1. After receiving the problems and solutions proposed by the property, the government affairs platform will classify them according to the problem type and transmit the relevant problems and solutions proposed by the property to the relevant functional departments; 8.2、Problem analysis: after receiving the problem, the relevant functional departments will review the problem and the property's solution; 8.3. Relevant departments intervene to handle the issue, connect with the owner and property management, and propose effective solutions to ensure that the problem is properly resolved and the legitimate rights and interests of the owner are fully protected; 8.4. After the problem is solved, the relevant departments will feedback the results to the government affairs platform, which will be transmitted to the urban service management center at the same time. The government affairs platform and the urban service management center will announce the results to ensure the transparency of information and the owners' right to know; As mentioned above, after the problem is solved, the government affairs platform will transmit the processing results to the urban service management center. The system of the urban service management center will automatically conduct a comprehensive analysis of these problems including the materials retained in the early stage. Similarly, when the owner asks similar questions in the future, the system can search for the problem. The solution provided by the property can be displayed to the owner for the owner's reference; Step 9: Government Affairs Interaction 9.1. Information release: relevant departments release some important information disclosure content to the government affairs platform and choose whether to synchronize it to the city service management center platform. If not, stop at this step. If synchronized, proceed to the next step. 9.2. Data exchange: The government affairs platform will publish the information disclosure content and transmit the information to the personal end of the mobile phone APP through information display.

[0021] To summarize, the specific implementation is as follows: Suppose an owner finds that the public facilities in the community are damaged, affecting the safety of residents. First, the owner selects the "Community Public Area Rights Protection" problem through the APP, describes in detail the time, place, and scope of the problem, and uploads relevant pictures as evidence. The system searches for similar problems. If the solutions to similar problems cannot solve the owner's problem, the owner submits the problem. The Urban Service Management Center receives the problem, classifies it according to the degree of urgency, and transfers it to the property comprehensive management platform. The property center decides whether to reply online or handle it offline based on the type and complexity of the problem. During the processing, the property center keeps in touch with the owner and updates the progress. After the problem is solved, the property platform will feedback the results to the Urban Service Management Center, which will show the processing results to the owner through the APP. If the owner is satisfied with the results, the problem is over; if not satisfied, you can choose government intervention and feedback to the government platform through the APP. The relevant functional departments will review and handle it, and the processing results will be fed back to the government platform, and then transmitted to the Urban Service Management Center, and finally displayed to the owner through the APP to ensure information transparency.

[0022] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
