The invention discloses a kind of method of automatic detection intelligent electric meter relay switching on, specific operating process includes the following steps：1) authentication is carried out on computers first；2) it after authentication success, is operated a switch or reclosing command by interface transmission；3) intelligent electric meter receive operate a switch or reclosing command after, control relay operates a switch or closes a floodgate, while returned data；4) by automatic detection device, read that relay is practical to operate a switch or "on" position, and whether correct judgment, if correctly, terminating flow；If incorrect, targetedly maintenance process is carried out.The present invention is by the way of automatic decision relay switching on, human factor is fundamentally prevented, the False Rate that relay switching on is tested is reduced to 0, it can ensure that intelligent electric meter reduces artificial erroneous judgement factor in process of production, improve the accuracy and reliability of relay switching on test, and whole process need not be participated in manually, no human factor influences, and accomplishes judging nicety rate 100%.
Description
Technical field
The present invention relates to intelligent electric meter control technology fields, and in particular to a kind of automatic detection intelligent electric meter relay drawing
The method of lock.
Background technology
Remote control relay switching on realizes that the power on/off of power consumer is a big notable function of intelligent electric meter, but from
Actually use situation from the point of view of, exist can not switching on the case where, intelligent electric meter in process of production, to the reality of relay switching on
Border motion test is all the method by manually seeing indicator light, is easy the presence of the case where artificially judging by accident, failing to judge.
Invention content
Goal of the invention：In order to overcome the deficiencies in the prior art, a kind of automatic detection intelligent electric meter relay is provided
The method of switching on can effectively improve production efficiency and judging nicety rate.
Technical solution：To achieve the above object, the present invention provides a kind of automatic detection intelligent electric meter relay switching on
Method, specific operating process include the following steps：
1) authentication is carried out on computers first；
2) it after authentication success, is operated a switch or reclosing command by interface transmission；
3) intelligent electric meter receive operate a switch or reclosing command after, control relay operates a switch or closes a floodgate, while returned data；
4) by automatic detection device, read that relay is practical to operate a switch or "on" position, and whether correct judgment, if just
Really, then terminate flow；If incorrect, targetedly maintenance process is carried out.
Further, it is obtained by network encryption machine with raising the price in the step 1, encryption data carries out authentication.
Further, it is operated a switch or reclosing command by the transmission of RS-485 interfaces in the step 2.
The present invention design principle be：For in intelligent electric meter production process, exist to relay drawing brake test artificial
The case where judging by accident, failing to judge obtains the switching on on-off signal of relay by automatic detection device using hardware circuit design,
By CPU and storage, the signal of acquisition is saved in storage chip, and is converted to the communications protocol format of agreement, computer expert
RS-485 interfaces are crossed, the data of automatic detection device storage inside is obtained, on off operating mode is judged after parsing and is shown to computer desk
On face, whole process need not be participated in manually, and no human factor influences, and accomplishes judging nicety rate 100%.
Advantageous effect：Compared with prior art, the present invention by the way of automatic decision relay switching on, fundamentally
Human factor is prevented, the False Rate that relay switching on is tested is reduced to 0, can ensure intelligent electric meter in process of production
Artificial erroneous judgement factor is reduced, improves the accuracy and reliability of relay switching on test, and whole process need not manually join
With no human factor influences, and accomplishes judging nicety rate 100%, therefore production efficiency is also significantly improved.
