Detailed description of the invention

As shown in the figure, the present invention includes server system, communication module, DBM, data monitoring module, it is characterized in that: the signal output port linking communications module of server system, DBM and data monitoring module, communication module includes order transmission and data receiving system, DBM includes monitor in real time, geofence and parameters revision system, and data monitoring module includes equipment control, systematic analysis and data maintenance system.

Server TT&C system forms with the pattern of client/server, and server is responsible for and the network request of user and communicating of industrial equipment hardware, simultaneously also in server end development data storehouse system, inquires about for manager, analyzes and safeguards. Supervisor as client can send request command to server, obtains every real-time parameter of the equipment being currently running and server can be allowed to judge whether this equipment works well according to each item data. And manager can also perform different operations according to different purposes, data base can be judged by the manager for being familiar with current device, safeguards and amendment. Such as the essential information of remote equipment is modified, change the Lower and upper bounds etc. of equipment normal operational parameters according to the difference such as region, weather. Therefore, manager can to home appliance in real time, history data is analyzed and compares, it is judged that equipment running status, providing the control instruction of corresponding state, thus realizing Remote closed loop control, improving reliability control system. Adopt the remote measurement and control management system that this pattern forms, by data management and data Communication Set process, not only increase security of system, also fully realize resource-sharing, further increase the effective rate of utilization of system resource. Except information equipment system manager, the access network that Web mode builds then can also be used for extraneous normal client, the present invention has more WML and the XHTML two such page-tag form being a bit to provide except HTML of breakthrough, user can be allowed far away from thousands of miles away, or even there is no when equipment for surfing the net to go to access server by the mode of WAP on mobile phone. The network built by the mode of WEB or WAP is as a kind of new network management approach, network manager can be allowed to use any Web browser, any node on network has access to Web server, conveniently promptly reads network management data, it is achieved the long-range operation to network. Web technology obtains with features such as the independences of its distinctive motility, ease for operation, distributed information processing and operating system and develops rapidly, native system uses Web technology except facilitating normal client, also alleviate server burden, after simultaneously facilitating, carry out systemic-function expansion.

Remote measuring and controlling system software design is divided by function mainly two parts: the related software design of server response to network, the controller based on LabVIEW virtual instrument designs. The core of network portion, is server subsystem. Server end has been responsible for tripartite's surface function, one is in response to the network request of user, the reading of data and communication, and two is data acquisition, analyzes and monitoring, carrying out reporting to the police or close hull closure etc. science and engineering when the data that note abnormalities occur to make, three is that data base designs, manages and safeguards. On controlled device, software aspects is except being decoded control instruction, performing, and mainly realizes remote server and equipment with the serial port protocol between hardware and control function. This information coding is built upon on all discernible basis of both sides, and both sides provide reliable coding to the other side, to meet the requirement of the network control system reliability to data and correctness. The serial ports at two ends can also set flow simultaneously, flow-control is provided, both sides both provide the transmission of fixed size and receive relief area, and recipient only allows sender to send oneself receptible data volume, it is prevented that fast sending out receives the fault receiving buffer overflow being likely to result in slowly. (1) equipment end intercepts the control signal from server end transmission or order, and timing is sent to the server end main running performance index (running voltage, operating current, temperature, fault, overvoltage, excessively stream etc.) from equipment. (2) equipment end is intended by sensor acquisition and preserves data.

The most work of data communication depends on server. For server, having two class clients, a class is the device clients of equipment oriented user, and a class is the client of network-oriented and data base administration. After client on connecting first is carried out identity and function checking identification by server, then give and corresponding authority. According to the user profile in data base, server, after equipment work with successful connection, judges whether its this user logs in, if then being selected to user by available for this server list of devices. Server can be set up with equipment as required and be connected, it can directly read the historical data that the user in data base, product information and equipment use and operates, can also send to equipment and control query statement, and the data that the instruction that user sends and equipment return preserve each through server and forward. Domestic consumer in this way, then authority is less relative to management personnel's authority, and mainly the browse queries of equipment job information, utilizes Web or Wap network mode to enter, easy to use, expands for systemic-function and also leaves wide space. In this programme, server software designs main JAVA language and writes, cross-platform for JAVA language and once compile the feature run everywhere, server software can be transplanted in other system easily, and JAVA language has the quick feature of response, so advantageous for our remote measurement and control all ratios. The subject matter that telecommunication is brought embodies both ways, it is simply that the problem of the effectiveness of network delay and data. When network delay is long, the working condition of server meeting function judgment device, replace manager to transmit observing and controlling instruction according to working condition, or close abnormal equipment. In order to ensure data validity, have employed the method synchronizing to obtain data, go and other process exclusives, ensure the accuracy of data so as far as possible.
