Electric quantity acquisition termination function tester
Technical field
The present invention relates to a kind of functional tester, relate in particular to a kind of electric quantity acquisition termination function tester, be particularly useful for electric power system electric quantity acquisition and maintenance.
Background technology
The electric quantity acquisition terminal is the basic equipment of electrical energy metering automated system, in the electrical energy metering acquisition system, bear the effect of forming a connecting link, be responsible for gathering, handle, store the various data on the ammeter, adopt various means of communications, stipulations by agreement provide data to main website, and it is to guarantee that electric quantity data is complete, basic accurately.Along with the expansion of electric energy metering system scale, need to insert a plurality of acquisition terminal equipment and kilowatt-hour meter usually.Though the stipulations of each device fabrication producer all support DL/T645 and IEC60870 ?5 ?102 stipulations because these stipulations are a framework, concrete details is not stipulated; And in specific implementation process, each implements producer and Utilities Electric Co. expands it respectively, causes differing greatly on the realization details, and stipulations also often have ambiguity on understanding, cause each producer's stipulations incompatible, often insert electric quantity collector and bring very big difficulty to kilowatt-hour meter.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of electric quantity acquisition termination function tester is provided, and it is incompatible to have solved in the prior art stipulations, is difficult to multiple kilowatt-hour meter is inserted the problem of electric quantity collector, and the present invention improved operating efficiency, and is easy to maintenance.
Technical scheme of the present invention is as follows:
Power supply links to each other with earth leakage protector, and earth leakage protector links to each other with AC converter, switch, computer, printer and electric weight concentrator respectively; AC converter all links to each other with kilowatt-hour meter stipulations simulator with the electric weight concentrator; Switch links to each other with computer with the electric weight concentrator respectively; Electric weight concentrator and computer are connected with telephone set respectively.
Described switch is the network switch.
Described electric weight concentrator links to each other with kilowatt-hour meter stipulations simulator by 485 interfaces.
Described power supply is 220 volts of AC power.
Advantageous effect of the present invention is as follows:
1, the present invention is according to generated energy acquisition terminal communication stipulations standard, the test terminal is to the support situation of multiple communication mode and communication protocol, the correctness of checking flow process, and the feedback information of acquisition terminal carried out analyzing and processing, form complete terminal test report, help the tester that the function of generated energy acquisition terminal is tested and assessed, also have certain accident analysis effect simultaneously.
2, the present invention carries out omnibearing function, flow testing analysis to terminal, in early days under the simulated environment for terminal provides detection means, in time find terminal defective, fault, thereby play the effect of shortening the engineering construction time and using manpower and material resources sparingly.
3, powerful, flexible operation, attended operation are convenient, are applicable to electric power system electric power system electric quantity acquisition and maintenance, have the prospect of using widely.
Description of drawings
Fig. 1 is a structural representation block diagram of the present invention.
Embodiment
The present invention in conjunction with specific embodiments, is described in detail as follows with reference to accompanying drawing.
Embodiment
220 volts of AC power link to each other with earth leakage protector, and earth leakage protector links to each other with AC converter, the network switch, notebook computer, printer and electric weight concentrator respectively; AC converter all links to each other with kilowatt-hour meter stipulations simulator with the electric weight concentrator, and the electric weight concentrator links to each other with kilowatt-hour meter stipulations simulator by 485 interfaces; The network switch links to each other with notebook computer with the electric weight concentrator respectively; Electric weight concentrator and notebook computer are connected with telephone set respectively.
Serial ports special line, dial telephone, TCP/IP network are supported to adopt in the test terminal.The invention provides the various communication interfaces mode, realize the real-time Transmission or the timing extraction stored record of Monitoring Data, Industrial Ethernet interface and the communication of distant place quality of power supply administrative center can be passed through, also the S232C/RS485 interface can be passed through, with GPRS mode and distant place communication.
The present invention can monitor the communication packet of uplink and downlink in real time, and can preserve, print message
Data in the uplink message are resolved, and can preserve, print.And the explain information of outgoing message.
The essential information (testing time, ERTU parameter, communications parameter) of this test of statistics and test command were carried out information (command type and parameter, execution result, error statistics etc.) after the present invention supported to test and finishes, the output test report provides test report output and printing function.
The present invention is except that having the monitoring of kilowatt-hour meter and collector and on the spot the writing function, can also distant place electric quantity acquisition center communication, with realize real-time power quality data on send, accept a distant place calling, parameter etc. is set.In the communication interface configuration of device, 100M is provided Ethernet interface, support ICP/IP protocol (comprising File Transfer Protocol).Except that the ether network interface, conventional RS232 and RS485 interface also is provided, can GPRS mode and distant place communication.
Protection scope of the present invention is as the criterion with claim, not limited by specific embodiment.
