Abstract
The utility model discloses multifunctional power consumption detection equipment comprising a plurality of current transmitters corresponding to each power consumption device, a PLC controller and a data display; one side of the PLC controller is provided with a plurality of sets of interfaces connecting the current transmitters; an interface on the other side of the PLC controller is connected with the data display; the multifunctional power consumption detection equipment can simultaneously test separate real time power consumption of at least two power consumption devices.
Description
Technical field
The utility model belongs to electrical instrumentation technical field, is 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 utility model 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 for the utility model:
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 utility model 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.
Accompanying drawing explanation
Fig. 1 is Multi-functional electricity-using amount assay device structures schematic diagram.
In figure: 1-first consumer 2-second consumer 3-the first current transducer
4-the second current transducer 5-PLC controller 6-HMI man-machine interface.
Embodiment
1 pair of the utility model is further described by reference to the accompanying drawings.
In the drawings, the first consumer 1 is transported to respectively the first current transducer 3 by wiring by electric current, the second consumer 2 connects the second current transducer 4 by wiring equally, one side of PLC controller 5 is provided with the many group interfaces that connect respectively the first current transducer 3 and the second current transducer 4, and PLC controller 5 opposite side interfaces connect HMI man-machine interface 6.
A kind of concrete implementation step of Multi-functional electricity-using amount checkout equipment is as follows:
When 1, the first consumer 1 is switched on, electric current is that the analog quantity that programmable device can be identified sends the PLC analog input module in PLC controller 5 to by the first current transducer 3, the first current transducers 3 by the current conversion of passing through;
When 2, the second consumer 2 is switched on, electric current is that the analog quantity that programmable device can be identified sends the PLC analog input module in PLC controller 5 to by the second current transducer 4, the second current transducers 4 by the current conversion of passing through;
3, PLC analog input module is converted to digital value by analog electrical value;
4, the PLC processing unit in PLC controller 5 reads the data that receive from PLC analog input module in real time, by writing relevant PLC program calculating, digital value is converted into real-time current value (determining according to the conversion value of current transducer).By real-time current value, calculate realtime power, can cross realtime power and calculate real-time electricity consumption data, then send electricity consumption data to HMI man-machine interface 6 by communication interface;
5, HMI man-machine interface 6 is responsible for showing the every data that receive from PLC, by configuration HMI man-machine interface 6, makes real-time the showing of every electricity consumption data.By the data that show, can see intuitively the realtime power of the first consumer 1 and the second consumer 2, real-time power consumption, power consumption per hour.By is set service time every day, can automatically demonstrate power consumption every day, monthly power consumption, annual power consumption.By comparing data can automatic decision at equivalent environment the first consumer 1 and the second consumer 2, which is more energy-conservation, more worth purchase.
