Be that example describes the function that how to detect electric energy meter in detail in IC-card, to write tripping operation information below.
Before the function to electric energy meter detects, need as shown in Figure 2 tested electric energy meter to be linked on the dial framework, the dial framework last time can be inserted a plurality of electric energy meters.
Suppose to measure relay tripping operation, closing function and the electric weight warning function of electric energy meter, need configure concrete testing scheme earlier, as shown in Figure 6, the invention process provided the concrete parameter data of testing scheme, the present invention only writes tripping operation information with Xiang Kazhong, and to make relay trip/close a floodgate be example.
Suppose that tested electric energy meter is the meritorious built-in magnetic latching relay IC-card of 220V 10 (60) the A prepayment meter of 3P4W.
Before the test beginning, the parameter of electric energy meter need be set, select ammeter type 3P4W active electric energy meter, the rated current of input ammeter is 10A, and maximum current is 60A, and voltage is 220V, and selecting the relay types of ammeter is " built-in magnetic maintenance ".
According to the above-mentioned electric energy meter parameter that configures, instruction sending unit sends the electric energy meter operational factor to the three-phase programmable power supply instruction is set, so that the electric current and voltage value of three-phase programmable power supply output regulation.Behind the magnitude of voltage and current value of three-phase programmable power supply output regulation, computing machine built-in MCU on dial framework sends and goes code, and after MCU received and goes code, pilot relay was connected IC-card read write line and IC-card.
After electric energy meter receives information, if electric energy meter can normally trip, relay will be carried out the tripping operation action, at this moment, the relay detection module sends to computing machine with the tripping operation information of relay, inform that computer relay carried out tripping operation, the status lamp that is used to monitor the electric energy meter state simultaneously also can send to computing machine with relay tripping operation information.
If computing machine is not a tripping operation information from the information that the relay detection module receives, the information that receives from the status lamp information that neither trip, electric energy meter can not normally trip, electrical energy meter fault.
When this IC-card was connected once more, whether the relay that also will detect electric energy meter can normally close a floodgate.
In the embodiment of the invention, status lamp is controlled by photodetector system, the photodetector system principle of work is: ammeter sends status signals such as warning, tripping operation, the process pulse shaping circuit leaches the burr signal in the pulse, different led state lamps shows different status signals, after led state is converted to level signal, is gathered by single-chip microcomputer, can be connected on the serial port of computing machine by 232 communication change-over circuits then, computing machine is received the status information of ammeter by the communication port extender.
The relay detection module is the relay status detection system, principle of work is: current sampling mutual inductor detects the electric current of the electric energy meter internal relay of flowing through, unlatching and the closed relay folding signal that produces according to relay switch, be level signal with relay folding conversion of signals then, send to the state-detection that computing machine carries out relay.
The present invention is example explanation the present invention to write tripping operation information in IC-card only, be not to be used for limiting the present invention, information in writing IC-card is when purchasing electric card information, IC-card just becomes purchases the electricity card, can write information such as purchasing electricity card sign, key information, information about power, tripping operation charge value information in IC-card, when the electric weight of purchasing the electricity card equals to trip charge value, detect electric energy meter and whether carry out tripping operation, when connecting IC-card once more, detect electric energy meter and whether continue operation according to dump energy.
