Embodiment
Below in conjunction with Figure of description the present invention is described further.
Like Fig. 1, shown in 2, a kind of electric energy balance monitoring system for transformer station comprises main station system, concentrator, acquisition terminal; Wherein main station system comprises database server, application server, front end processor.The function of main station system is the parameter and the data of sending instruction read-write concentrator and acquisition terminal downwards, and the database of foundation oneself is preserved data; Front end processor provides the function of data forwarding; The function of acquisition terminal is to gather real-time energy data; Concentrator has the function of AC sampling and copy reading ammeter, and can periodically preserve the related data of electrical network, and the data that collect and be transmitted to main station system.
The electric energy balance monitoring system connected network communication; For system can be connected as one, let component commands of electric energy balance system divide and carry out swap data.Said application server passes through too, and the mode of net, GPRS or phone Modem is connected communication with preceding front end processor; Said front end processor is connected communication through the mode of Ethernet, GPRS or CDMA with concentrator, and said concentrator is connected communication through the mode of 485 interfaces or small wireless with acquisition terminal; The communication of so just accomplishing whole system connects.Through the mode of this link, after connecting completion, directly issue parameter and the data that claim frame is read and write acquisition terminal through main station system.This connection can all link together whole system, thereby can control total system fully.In addition, the main station system support of monitoring system connects acquisition terminal through the serial port of computer, and main station system can directly issue the parameter and the data of claim frame read-write acquisition terminal like this.
Said front end processor comprises external communication part, producer's analytical analysis part, Communications service program; For uplink information: after the external communication part through front end processor receives; Carry out the decoding of Communication Layer; Obtain the application layer message of stipulations; Do following the processing according to the type of application layer message then: standard message is given processings that make an explanation of main website rig-site utilization service routine, sends manufacturer's routine analyzer of decoding simultaneously to; Non-standard message is submitted corresponding manufacturer decoding routine analyzer to according to different manufacturers; Manufacturer's decoding routine analyzer can be given front end processor Communications service program with analysis result according to the standard message form with the form of uplink message, is transmitted to application server after Communications service is received; For downlink information: manufacturer's decoding routine analyzer will be called together with the form of downlink message and surveyed order and send to front end processor Communications service program, be transmitted to concentrator after the Communications service program is received; The communication of being initiated by application server in addition issues through standard message without exception.
Native system realizes that the step of electric energy balance monitoring is following:
A. task configuration; Application server initiatively reports task or concentrator copy reading acquisition terminal task through front end processor configuration concentrator;
B. data report; Through acquisition terminal, obtain the real time data of electrical network, concentrator is gathered the data of acquisition terminal, and initiatively reports main station system to the data that collect; Acquisition terminal itself comprises the function of AC sampling, so acquisition terminal can measure the real time data of electrical network; In addition through task configuration at main station system; After the configuration of each measurement is accomplished, through the configuration task of main station system, behind the concentrator task run to the terminal of concentrator; Concentrator can periodically read the data of acquisition terminal, and periodically reports up main station system; Through these modes, main station system just can obtain the electric network data that the acquisition terminal AC sampling records according to certain hour at interval, and preserves;
