Abstract
The invention discloses an automatic electric energy meter switching-out or switching-on test circuit capable of being integrated into a meter calibrating table. The test circuit comprises a photocoupler connected with a switching-out or switching-on module of an electric energy meter, a central processing unit (CPU) which is connected with the photocoupler and is used for detecting a switching-out or switching-on state of the electric energy meter, and a communication module which uploads the state of the electric energy meter acquired by the CPU to an upper computer, wherein the input end of the photocoupler is connected with the switching-out or switching-on module of the electric energy meter; the output end of the photocoupler is connected with the CPU; and a relay is arranged between the photocoupler and the CPU. The invention has the advantages that: the test circuit can be integrated into the automatic meter calibrating table and has the function of automatically detecting the switching-out or switching-on of the electric energy meter; the labor intensity is low; the error judgment rate is low; manual hot line work is not required; and the safety is high.
Description
Technical field
The present invention relates to a kind of automatic testing circuit that detects electric energy meter drawing lock function, particularly a kind of electric energy meter drawing lock automatic testing circuit that is integrated in correction platform or the monitor station.
Background technology
Large batch of activity in production along with electric energy meter; Manual test pattern in the past can not well reach production requirement; Manual test tends to cause mistake survey, test leakage, and causes following the tracks of product quality, can't improve Production Line efficient; Reduce manually-operated and judgement, improve the quality of products.So we must go to change to automatic mode from manual test pattern in the past; The drawing lock function that needs more high efficiency detection electric energy meter; The drawing lock that comprises single-phase table and three-phase table, the drawing lock function to the multichannel electric energy meter that like this can be concurrent more fast detects.
All the time, the test of electric energy meter all rests on manual testing's stage, aims at test point through testing staff's manual test rod, and project of every test is changed different test points, and the testing staff is with the forceful electric power operation, very easily causes electric shock accidents.
Summary of the invention
Rest on manual testing's stage for overcoming existing electric energy meter test; Testing staff's labour intensity is big, False Rate is high, and artificial hot line job, very easily causes the shortcoming of electric shock accidents, the invention provides a kind ofly be integrated in the auto-adjustment platform, robotization detects electric energy meter drawing lock function; Labour intensity is low; False Rate is low, need not artificial hot line job, the electric energy meter drawing lock automatic testing circuit of safe be integrated in correction platform.
Can be integrated in the electric energy meter drawing lock automatic testing circuit of correction platform; Comprise the optocoupler that is connected with the drawing lock module of electric energy meter; Be connected with optocoupler, be in and operate a switch or the CPU of "on" position and the electric energy meter state that CPU obtains is uploaded to the communication module of host computer to detect electric energy meter;
The input end of described optocoupler is connected with the drawing lock module of electric energy meter, and the output terminal of described optocoupler is connected with CPU, is provided with relay between described optocoupler and the described CPU.
Described communication module is 485 communication modules.
Technical conceive of the present invention is: host computer sends electric energy meter and operates a switch or reclosing command, at this moment relay closes.When electric energy meter closed a floodgate, the illuminator of optocoupler was lighted, and the light-receiving device of optocoupler is passed to CPU with the electric energy meter "on" position after sensing light signal; When electric energy meter was operated a switch, the illuminator of optocoupler extinguished, and the light-receiving device of optocoupler can't be sensed light, then think that electric energy meter is in the state of operating a switch, and this status signal of operating a switch is passed to CPU; CPU transfers to host computer through communication, and host computer sends the status signal of CPU passback with it instruction comparison if the status signal that returns conforms to the instruction that host computer sends, is then thought the drawing lock module operate as normal of electric energy meter.
Between optocoupler and CPU, relay is set; When host computer did not send the instruction of drawing lock, when promptly monitor station or correction platform were not tested electric energy meter drawing lock, relay broke off; The disconnection of optocoupler and CPU; The present invention does not work, and optocoupler can not cause current loss to monitor station or correction platform, ensures the degree of accuracy of monitor station or correction platform.
The present invention have can be integrated in the auto-adjustment platform, robotization detects electric energy meter drawing lock function, labour intensity is low, False Rate is low, need not artificial hot line job, safe advantage.

Embodiment
With reference to accompanying drawing, further specify the present invention:
Can be integrated in the electric energy meter drawing lock automatic testing circuit of correction platform; Comprise the optocoupler that is connected with the drawing lock module of electric energy meter; Be connected with optocoupler, be in and operate a switch or the CPU of "on" position and the electric energy meter state that CPU obtains is uploaded to the communication module of host computer to detect electric energy meter;
The input end of described optocoupler is connected with the drawing lock module of electric energy meter, and the output terminal of described optocoupler is connected with CPU, is provided with relay between described optocoupler and the described CPU.
Described communication module is 485 communication modules.
Technical conceive of the present invention is: host computer sends electric energy meter and operates a switch or reclosing command, at this moment relay closes.When electric energy meter closed a floodgate, the illuminator of optocoupler was lighted, and the light-receiving device of optocoupler is passed to CPU with the electric energy meter "on" position after sensing light signal; When electric energy meter was operated a switch, the illuminator of optocoupler extinguished, and the light-receiving device of optocoupler can't be sensed light, then think that electric energy meter is in the state of operating a switch, and this status signal of operating a switch is passed to CPU; CPU transfers to host computer through communication, and host computer sends the status signal of CPU passback with it instruction comparison if the status signal that returns conforms to the instruction that host computer sends, is then thought the drawing lock module operate as normal of electric energy meter.
Between optocoupler and CPU, relay is set; When host computer did not send the instruction of drawing lock, when promptly monitor station or correction platform were not tested electric energy meter drawing lock, relay broke off; The disconnection of optocoupler and CPU; The present invention does not work, and optocoupler can not cause current loss to monitor station or correction platform, ensures the degree of accuracy of monitor station or correction platform.
The present invention have can be integrated in the auto-adjustment platform, robotization detects electric energy meter drawing lock function, labour intensity is low, False Rate is low, need not artificial hot line job, safe advantage.
