Description

Client's electricity consumption situation wireless acquisition device

Technical field

The utility model relates to anti-theft electricity technology, specifically is a kind of client's electricity consumption situation wireless acquisition device.

Background technology

Grid line loss is made of theory wire loss and management line loss.The management of national grid line loss explicitly calls for the management line loss must not surpass 10% of generated energy, and one of principal element that causes the management line loss is stealing.Present anti-theft electricity technology mainly comprises casual inspection, generaI investigation, mis system analysis etc.; The main limitation of existing anti-theft electricity technology be that labor intensive financial resources, stealing evidence are difficult to obtain, the stealing loss is difficult to accurately define and can't monitoring form before stealing; Be necessary to invent for this reason a kind of time saving and energy saving, easily obtain the stealing evidence, can accurately define the stealing loss, can monitoring form before the novel anti-electricity-theft device of stealing.

Summary of the invention

The utility model is difficult to obtain in order to solve existing anti-theft electricity technology labor intensive financial resources, stealing evidence, the stealing loss is difficult to accurately to define and can't monitoring form before the problem of stealing, a kind of client's electricity consumption situation wireless acquisition device is provided.

The utility model is to adopt following technical scheme to realize: client's electricity consumption situation wireless acquisition device comprises wireless collection device and wireless receiver; Described wireless collection device comprises current transformer, sample circuit, A/D modular converter, first embedded microprocessor, first memory and first wireless little power consumption module; Wherein, the output terminal of current transformer connects the input end of sample circuit, the output terminal of sample circuit connects the input end of A/D modular converter, the output terminal of A/D modular converter connects the input end of first embedded microprocessor, the output terminal of first embedded microprocessor connects the input end of first wireless little power consumption module, and the data terminal of first embedded microprocessor connects first memory; Described wireless receiver comprises second wireless little power consumption module, second embedded microprocessor, second memory and output interface circuit; Wherein, the output terminal of second wireless little power consumption module connects the input end of second embedded microprocessor, and the output terminal of second embedded microprocessor connects output interface circuit, and the data terminal of second embedded microprocessor connects second memory; The input end wireless connections of the output terminal of first wireless little power consumption module and second wireless little power consumption module; Described first wireless little power consumption module, second wireless little power consumption module are existing known configurations.

During work, the wireless collection device directly overlaps/is serially connected in the client and specially becomes on the primary side high-voltage power line, and wireless receiver connects the electricity management terminal that is built-in with the stealing expert system by output interface circuit; The concrete course of work is: the primary side current current transformer of flowing through obtains induction current, induction current is converted to digital signal and send first embedded microprocessor after sample circuit, A/D module processing successively, after first embedded microprocessor calculates, stores and handles, transmit current data information to wireless receiver by first wireless little power consumption module; After second wireless little power consumption module receives the wireless signal that primary side wireless collection device sends, is the primary side current data through demodulation with analog signal conversion, and this current data has just been finished the receiving course of data after second embedded microprocessor calculates, handles and stores; In this process, the stealing expert system in the electricity management terminal is by carrying out defining of the obtaining of stealing evidence, stealing loss to carry out the stealing analysis from the data of wireless receiver, and stealing is monitored before the his-and-hers watches simultaneously; Compare with existing anti-theft electricity technology, that client's electricity consumption situation wireless acquisition device described in the utility model has is time saving and energy saving, obtain the stealing evidence easily, can accurately define the stealing loss, can monitoring form before the characteristics of stealing.

The utility model is simple in structure, reasonable in design, efficiently solve that existing anti-theft electricity technology labor intensive financial resources, stealing evidence are difficult to obtain, the stealing loss is difficult to accurately to define and can't monitoring form before the problem of stealing, be suitable for the anti-electricity-theft use of power supply enterprise.
