1 Research and Development of J2EE Architecture-based Intelligent Community Management System Yang Rui 1, 2, Qixiu Yang 1, 2 1 School of Social Work, Chongqing City Management College, Chongqing , China 2 Library, Chongqing City Management College, Chongqing , China Abstract In recent years, intelligent city has become the mainstream of urban construction, and among it, intelligent community is the core part in intelligent urban construction. Intelligent urban construction in our city is still at the preliminary stage, and due to the wide gap generally existing in input and understanding on intelligent community, the unbalanced development of intelligent community and unevenness of informatization construction further result in the lack of information exchange among community management departments, etc. Under the driving of technology and the support of policy in newly-built urban area, in order to make the citizen enjoy the digital life of intelligent community and change the community management method, it's proposed to build the intelligent community platform. In this context, this Paper designs a set of J2EE architecture-based intelligent community management system for these intelligent communities in newly-built urban area, in the hope of helping community management improve the comprehensive management level and enhance their capacity in public service for community residents. Keywords: Intelligent Community, J2EE Architecture, System Development, Model Framework. 1. BACKGROUND 1.1 Literature review Community is the basic unit of urban development, and its development directly concerns all aspects of community residents' daily life. However, along with the continuous improvement of people's living level, current community management may not satisfy the continuously-growing demands of the residents any longer. The continuous development and popularization of the information technology may help community management department realize the informatization of management and services, and accordingly form an efficient and convenient public administrative method (Wang and He, 2014). In addition, community residents may also enjoy the convenient life service brought by informationalized community management. Therefore, in order to realize the integration of community management and service, it requires a more "intelligent" method for solving today's issue. The birth of intelligent community may solve the issue through an "intelligent" method. The application of today's advanced technology may help intelligent community realize the information exchange among community management, users and intelligent community system. In this way, on one side, the user may not only experience the digital life brought by intelligent community, but also, on the other side, the community management apply a more convenient management method (Jin, 2014). Intelligent community is the highly integrated product of today's informatization technology and it integrates the emerging technologies involving cloud computing, internet of things, mobile internet, GIS technology and positioning technology, etc. Intelligent community management system is the main part of intelligent community, which, from the perspective of community administrators, provides the corresponding informatization application, in the hope of helping improve the efficiency and scientificity of community management. While providing the advanced technical means, community informatization management will also promote the development and improvement of community management mode, including optimization of business process, coordination and integration among different departments, introduction of grid management, building of internal and external combined evaluation supervisory mechanisms, etc.; management features more intelligence than technology to some extent. 636

2 1.2 Objective of the study This Paper conducts in-depth study on management situation of community administrators' daily work, and with community development as the premise and by combining the currently relative mature community informization technology and leading solutions, designs and develops a set of safe, stable, advanced and intelligent J2EE architecture-based intelligent community management system, bringing forward the study on application of ant colony-based improved shading algorithm in GIS technology in community management, and designing and developing the redeveloped mobile application module for WeChat enterprise number (Li, 2014), through which realize the improvement of comprehensive management level of community management departments and the enhancement of capacity of public service for community residents, improving the efficiency of management and service of community management departments, so as to further benefit the community residents' daily life. 2. OVERVIEW OF J2EE ARCHITECTURE 2.1 Definition of J2EE J2EE (Java 2 platform enterprise edition) is a specification defined by SUM company, which is for simplifying the development and deployment of enterprise-level application. Java or J2SE (Java 2 Platform Standard Edition, Java 2 platform standard edition) is the core foundational technology of J2EE, beside the supporting to Servlet, Bean, JSP and XML, P2EE also solidifies the basic characteristics of J2SE (Li, 2017). For instance, its characteristics of "as long as being compiled once, it will be able to run in other java environment", the application of JDBCAPI and CORBA (Common Object Request Broker Architecture) technology may realize the convenient storage of data in database and feature the safe mode of J2EE, etc. J2EE makes the development of enterpriselevel development become simpler and faster. 2.2 B/S/S architecture The three layers of B/S/S S structural browser/web server/database server (Web Server/Database Server) are as shown as Figure 1. The design thought of three tier framework may combine the J2EE's multilayer application architecture to realize extension and between the layer of terminal user and final data, establish the access layer and service layer (wherein, access layer includes business logic and display logic, and service layer refers to the intermediate application), which are designed as per multilayer mode. Figure 1. B/S/S Multilayer Architecture According to the complexity and maintainability of applications, three-tier architecture features more advantages comparing with two-tier architecture and single-tier architecture, and it may optimize the coupling relationship and is convenient for work breakdown. Three-tier architecture adapts to team development, in which team, each person may engage in different work and however has to collaborate, making the efficiency of work being doubled (Xu, 2016). Three-tier architecture is a thin client mode, and even there's only a smaller disk with less memory space in terminal user and slow speed of CPU, may also acquire good performance. Comparably, single-tier architecture and fat client mode make excessive demands on the machine, and the biggest advantage of three-tier architecture is its safety performance. Its safety performance embodies: at client terminal, one can only access the data layer through logic layer, which may accordingly reduce the access point of data layer access, with many hazardous system functions being interdicted. 2.3 Ant colony optimization Ant colony (ants) optimization is a probability algorithm searching optimized path in Figure G, which is a population-based heuristic bionic evolution system (Wu, 2015). When ant colony searches food sources, each ant 637

3 decides the walk route according to the concentration of volatile substance (pheromone) released by other ants on the route, and releases the pheromone to improve the quantity of pheromone on the route. The higher the concentration of pheromone on the route, the bigger chance the ants selects it. However, the concentration will weaken as the time goes on. Assuming "G (V, E)" - undirected acyclic graph, "V=(v 1, v 2,, v n)" refers to the preliminary point sequence randomly generated in Figure G. "P" refers to the biggest degree at the peak point, i.e. the upper bound of chromatic number in Figure G; assuming "C=(c 1, c 2,, c p)" as color set, assuming "G (V, E)" - undirected acyclic graph, i.e. the vertex sequence randomly generated in Figure G. Assuming "D (n*n)" as the adjacency matrix of Figure G, meeting the following equation: D(i, j) = { 1 if v i is adjcent to v j 0 else (1) "S" meeting the following assumption: using color table (matrix) "S (n*p)" to record the coloring process of ant "k", " S (i, j)=1" representing that ant "k" passes "S (i, j)", and using color "C j" to color the point "V i". "S" meeting the following equation: S(i, j) = { 1 color v i with c j 0 else (2) And after all ants separately finish the coloring process, "S" meeting the following equation: p j=1 S(i, j) = 1 (3) Assuming "r (n*p)" as pheromone matrix, wherein, "r(i, j)" representing to use color "C j" to color the pheromone of point "V i", which corresponds to color table "S (n*p)", and the pheromone equation is updated as ("p" refers to the volatility of pheromone, generally taking 0.3). τ ij (i, j) = (1 p)τ ij (i, j) + τ(i, j) (4) Wherein, " τ k (i, j)" refers to the pheromone released by ant "k" when it uses color "C j" to color point "V i" ("Q" refers to the concentration of pheromone, generally taking 1). τ(i, j) = m k=1 k (i, j) (5) τ(i, j) = Q/NumC (6) Assuming "η ij " is extended as heuristic information (NumC: V i-1 refers to the total quantity of colors after being colored): η = 1/NumC When ants wander to color, transition probability "P ij k " help decide to use color "C j" to color point "V i". P ij k = { α β τ ijηij τ α β isηis c j allowd i k 0 else (7) Wherein, " α, β " are the parameters that influence the decision of ants by pheromone " τ " and heuristic information " η (α, β = 1, 2, 3, 4)". "allowed" refers to the feasible coloring set of point "V i" in the coloringfinished set "{c 1, c 2,, c NumC}"when ant "k" colors point "V i", and if allowed is not in empty, then, transition probability " P ij k " uses color "C j" to color point "V i", and "allowed" is for "V i", color "c NumC". And, then, NumC=NumC

4 3. ANALYSIS ON DEMANDS OF THE SYSTEM 3.1 Demands on functions With regard to functions, the intelligent community with community residents as the core of service is required to guarantee the community residents' daily life and meet the development demands, offering the residents the efficient, convenient and safe intelligent service; with regard to community management level, the management of intelligent community is through a sub-system of intelligent community system, intelligent community is the important part of intelligent city, and the management of intelligent community is through an efficient and comprehensive community information management platform (Li and Zhuang, 2017). The objects accessing and using intelligent community management system mainly are leaders of civil administration departments and community worker. According to the actual requirements, the system may be divided into 6 sub-systems as shown as Figure Grid management sub-system Figure 2. Hui Community Management System Function Module Under the premise of none big change to the entire layout of the cities, communities and streets, the primary management area is divided by grid and one area may be divided into several unit grids. E.g. with regard to community management, a neighborhood committee area may be divided according to the actual situation. Then the grid administrator will be responsible for the management of the people, things, affairs and organizations, etc. in the grid under his charge, realizing the meticulousness, informatization and dynamisms of service management and accordingly increasing the efficiency of the management (Fei, 2017). Grid management is based on GIS technology, through which directly present all data and information in the unit grid and upgrade the data and information in real time. In addition, it may also help realize the real-time positioning of administrators according to the information on physical community houses and buildings. Each grid administor of the community may not only manage the people and things, etc. in the grid, but also should serve the community residents. Through dividing the community into unit grid, realize "zero" social service, "full coverage" social management and "complete response" to residents' appeal. Grid management sub-system includes grid division, information management, work management and performance evaluation with regard to grid administrators Affair management sub-system Affair Management Sub-system mainly solve the daily affairs related to the community. The sub-system includes event treatment, government affairs handling and comprehensive evaluation, etc (Song and Shao, 2017). Event treatment helps all level managements coordinate and handle the events reflected by basic level, mainly including information reporting, information distribution and transferring, and event feedback, etc. Government affairs 639

5 handling: at business hall and on community website platform, handle the data provided by individuals or enterprises, etc., and according to the business type, the data are sent to the corresponding business department for handling, and feedback the business processing situation to the user after the business is completed. Comprehensive evaluation: apply a set of scientific and complete supervision and evaluation system to assess and evaluate all circles of community management, through which may not only supervise the problems appeared during social management, but also may supervise the quality of management and enforcement, with the functions including personnel evaluation function, department evaluation function and area evaluation function, etc Conflict resolving sub-system Through conflict resolving sub-system, service worker at all levels handle daily affairs. Under the sub-system, daily affairs consist of my affairs and subordinate affairs, and while helping the service worker handle their own daily work, the sub-system may also supervise the subordinate worker to carry out their work better (Yang, 2017). Its functions mainly include service event registration, event processing, urgent event processing, leader approval, historical affairs, work supervision, typical case and statistical analysis, etc Daily work sub-system Daily work sub-system, by applying and compiling annual standing book and log book, reflect the content description of annual work and daily work of all departments and organizations in the community. The catalog of standing book may include dispute troubleshooting report, public security and random point regulation report, important conference, important documents, key events and special work, etc Personnel management sub-system The sub-system manages the information about "two committee" members and full-time worker of the community, including mastering of dynamic conditions and precision management with regard to basic information, team structure, salary subsidies, and promotion and job change, etc Assessment & evaluation sub-system Assessment & evaluation sub-system, according to community assessment methods and by combining the relevant data related to the system, evaluate the subordinate organizations and personnel (He and Yang, 2016). The functions of the sub-system include management of assessment rules, evaluation by supervisor and evaluation by subordinate worker. 3.2 Analysis on demands in WeChat enterprise number Along with the rapid progress of mobile internet, various emerging mobile technologies appear, and the dispute in localization application and HTML3 technology is becoming increasingly fierce. The WeChat released by Tencent, especially the appearance of WeChat subscription number, WeChat service number and enterprise number bring great impact on traditional information system. The development of WeChat-based application makes a great progress, and such development mode is generally recognized by many enterprises for its improvement in development efficiency and development time. During grid division process, according to relevant stipulation, appr. 800 residents constitute a grid, and several grids constitute a community, through which way, a community consists several sub-communities. Intelligent community management is introduced into the secondary development of WeChat enterprise number, and each sub-community applies one WeChat enterprise number to release the mobile applications at WeChat platform by combining the advanced technology from the actual work of community management worker (Bei, 2015). The secondary development of WeChat enterprise number aims at managing the daily work of community worker via remote mobile terminal, which mainly involves attendance system, mission system and information transmission as shown as Figure 3. As long as a WeChat enterprise number is established for the application by one subcommunity, such number could also be applied mechanically by other sub-communities. 640

6 Figure 3. WeChat Enterprise Number Function Module Attendance system The system mainly consists of sign in function and sign out function. Both functions are required to be completed within a certain time range and spatial range, with the main process as shown as Figure 4 (with sign in function as the example). Figure 4. WeChat Sign in Process The user opens the sign in application, and the application jumps to sign in interface after authentication. WeChat sign in is judged according the given physical scope, and therefore, the first step is to position the positioning system, acquire the current position of the user, and judge whether the user's position is within the given physical scope (Zhang and Deng, 2015). Within the scope, the sign in may be realized through the shake of the mobile or the click of "sign in" button. During the sign in process, the first step is to judge whether it's within the sign in period, if yes, the sign in time and situation of the very worker shall be recorded. By now, the whole processes are finished. Sign out process is basically the same as sign in process. Sign in function and sign out function are for recording the worker's work time, offering reference for the evaluation of daily work of the worker. 641

7 3.2.2 Mission system Mission System mainly includes the filling of daily tasks, assignment of worker's daily work by leaders and management of unfinished task. Adding tasks: the user opens sign in application, and the application jumps to task adding interface after authentication. Different functions are assigned as per the users' roles (Mai, 2015). Common worker may only fill in their own daily tasks, and the leaders may not only fill in their daily tasks, but also select tasks to assign to the worker and transfer the information of the tasks assigned to corresponding worker. After the worker finishes the task, the information on task achievement shall be fed back to the leaders who have assigned them the tasks. Task assignment is as shown as Figure 5. Figure 5. WeChat Assignment Management of unfinished tasks: the tasks filled in by the workers or the leader represent unfinished tasks, and after being finished, the task state shall be changed into task achievement. Should the task fail to be finished within stipulated time, the task state may automatically changed into task postponed and postponed causes shall be indicated; after the task is finished, the task state shall be changed into task achievement and the completion time shall also be recorded. Should the task not be finished, the cause resulting in failure shall be indicated and the state shall be indicated as 'Unfinished" Functions about sending text and graphics-text related information In intelligent community management system, some information (incl. the task assigned to the workers by the leader, the task assigned by the leader and finished by the workers) is required to transfer to community worker timely, and community worker shall accordingly complete the corresponding work according to the received information. The transfer of such information may be completed through WeChat enterprise number (Li, 2015). WeChat enterprise number offers the developer the E1 links for transferring information, and through the links, the transfer of information may be easily realized. In conclusion, the development of WeChat enterprise number offers the intelligent community the evidence for managing worker performance evaluation with regard to workers' daily work situation and attendance situation in the system, which is not only beneficial to the improvement of work efficiency of community management and government administration level, but also beneficial to the improvement of government's decision-making and emergent treatment capability, and the optimization of government service function as well. 4. CONCLUSION This Paper firstly establishes the overall framework for intelligent community management system, then divides it into specific function modules according to the overall framework of the system and the daily work & business process of community management, and analyzes the specific demands in the module, so as to make it meet the community management work. Then, conducts detailed analysis on the demands of mobile application, adopts WeChat enterprise number to conduct the secondary development of mobile application, and analyzes the function of demand module of mobile application in details, including attendance module and daily task management function and other modules, through which realizes the demands on remote management of workers' daily work.
