Description
Affiliated technical field
The utility model relates to the real time monitoring apparatus of a kind of supervising device of electric energy meter, particularly generating plant and regional power grid gate energy meter.
Background technology
The electric weight that gate energy meter measured of generating plant and regional power grid is related to sale of electricity and with the economic interests of electric unit, even the fault of short period occurs, also will causes great economic loss to a side; In these gate energy meters, though the electric energy meter that has had at present has the function of warning,, if there is not the equipment that can in time handle these information, the scene does not have the technical professional again, just can't in time find fault; Moreover these electric energy meters all are merely able to own situation itself is monitored, and can't monitor simultaneously and manage numerous electric energy meters, in case table meter itself break down, just can't output alarm signal;
Summary of the invention
The purpose of this utility model provides a kind of electric energy meter supervising device, can realize numerous electric energy meters is monitored in real time.
The technical scheme that its technical matters that solves the utility model adopts is: this supervising device is made up of signal picker, signal processor, display, alarm, power supply and cabinet etc., be characterized in: signal picker is made up of RS422, RS485 serial line interface and a switch value input interface, input interface is connected with multiple a plurality of electric energy meters, gather the electric parameter (each phase voltage U, electric current I and the power P of electric energy meter) and the switch alerting signal at electric energy meter place, serial line interface is connected with data bus with the serial line interface of signal processor respectively with switch value input interface; Signal processor is made up of single-chip microcomputer and peripheral circuit thereof, and it is handled by the signal that collector is sent here, finish to connection electric energy meter ruuning situation and the judgement of fault such as decompression, under-voltage, three-phase imbalance and false wiring; Signal processor is connected with display with control line by data bus, and video data and result connect alarm by an I/O interface, send alerting signal.
Alarm is made up of light news Chinese percussion instrument material and one group of passive switch, the realization of the sound and light signal of this locality when light news Chinese percussion instrument material is used to report to the police, and passive switch is used for alerting signal is sent to a distant place;
Also have a keyboard, form, send into single-chip microcomputer, realize default and man-machine conversation by data bus by " inquiry ", " time ", " ▲ ", " ", " removing " 5 groups of switch keys.The beneficial effects of the utility model are:
The alerting signal value sent of electric parameter signal by reading electric energy meter one place and electric energy meter itself only, just can finish the numerous electric energy meters of booster stations or transformer station of generating plant, regional power grid are monitored in real time, improve the electric energy meter reliability of operation, guarantee the accurate and just of electric energy metrical.
