A kind of Multi-functional electricity-using amount checkout equipment

Technical field

The invention belongs to electrical instrumentation technical field, be specifically related to a kind of Multi-functional electricity-using amount checkout equipment.

Background technology

Consumer power consumption statistics is all to add up power consumption by electric energy meter at present, but power consumption data can only add up, function is relatively single, as need be tested the real-time power consumption of difference of the consumer of at least 2 simultaneously, come more different use electric loading power consumptions per hour, every day power consumption, data such as power consumption, annual power consumption monthly.Existing electric energy meter cannot meet this requirement.

Summary of the invention

The present invention has overcome deficiency of the prior art, and a kind of equipment that can simultaneously test at least 2 real-time power consumptions of consumer is provided.

For achieving the above object, the technical scheme of employing is as follows in the present invention:

A Multi-functional electricity-using amount checkout equipment, comprising: each consumer is a plurality of current transducers one to one, PLC controller, data display equipment; One side of described PLC controller is provided with the many group interfaces that connect current transducer, and described PLC controller opposite side interface connects described data display equipment.

The processing module that it is analog quantity that described current transducer comprises current transitions can processed module change analog quantity into after the electric current of consumer is by current transducer.

Described PLC controller comprises PLC analog input module and PLC processing module, described PLC analog input module changes for receiving from described current transducer the analog quantity obtaining, described PLC processing module, for receiving the analog quantity of sending from PLC analog input module and transferring analog quantity to electricity consumption data by processing module, finally sends to described data display equipment by communication interface again.

Described data display equipment is HMI man-machine interface.

Described Multi-functional electricity-using amount checkout equipment can show that the consumer detecting is per hour, every day, monthly, annual electricity consumption data.

The beneficial effect that the present invention compared with prior art has: each consumer current transducer that can connect one to one, the analog data that each current transducer obtains conversion is again transported to PLC controller, by PLC controller, process the real-time electricity consumption data that calculate each consumer, finally in HMI man-machine interface, show together, can test so the real-time power consumption of difference of at least 2 consumers simultaneously, more different consumers power consumption per hour, every day power consumption, data such as power consumption, annual power consumption monthly.
