Owing to the existence of stealing electricity phenomenon for a long time, power supply supervisory department can't realize finding accurately in real time by traditional investigation means, has caused enormous economic loss to power supply department in addition.
Summary of the invention:
The utility model is at above-mentioned prior art situation, and a kind of intelligent wireless supervision of power consumption system is provided, this system can gather that gauging table breaks down or the people for the information of stealing, send relevant information to power department, power department can be reacted rapidly.
The purpose of this utility model realizes by following measure:
A kind of intelligent wireless supervision of power consumption system, it is characterized in that, this system comprises supervision end and service end, and the note and conversation module of being responsible for supervision end and service end communication, described supervision end comprises DSP control system, recording system, signal acquiring system, USB flash disk storer and man-machine interface, described recording system, signal acquiring system, USB flash disk storer and man-machine interface are connected with the DSP control system by corresponding interface respectively, described DSP control system receives the also abnormal signal of analytic signal acquisition system, sends service end to by note and conversation module.
The mode of SPI three wire serial bus is partly adopted in recording with the communication of DSP part, adopt parallel communication mode, the communication between SMS module and the DSP control system to adopt UART three-wire system mode between storer and the DSP control system.
It is that transmission platform and service end are carried out communication that note adopts public mobile communications network GSM, CDMA or 3G third party's network with the conversation module.
Signal acquiring system comprises voltage transformer (VT), wave filter, sampling holder, the AD converter that links to each other successively.
The DSP control system sends information with the form of note to service end.
By man-machine interface the supervision end is provided with, and shows relevant information.
The utlity model has following advantage:
The metering outfit of the utility model cooperated power supply department is used, and when causing electrical network parameter unusual when electricity consumption metering outfit fault or owing to stealing, signal acquiring system is gathered relevant information, also produces the fault conclusion through the DSP control system analysis.The fault conclusion sends to the service end of power supply department through SMS module, and power department can be reacted rapidly.And dependent event is recorded in the USB flash disk storer, convenient dispute is in the future checked.The contact of conversation module aspect power supply department and electricity consumption enterprise.Therefore the utility model has made things convenient for the supervision of power department to electrical network, and bigger social benefit and economic benefit are arranged.
Description of drawings:
Fig. 1 is a principle of work block diagram of the present utility model.
Fig. 2 is the schematic diagram of signal acquiring system.
Embodiment:
Provide embodiment below in conjunction with accompanying drawing, the utility model is described in further detail.But given embodiment can not be interpreted as the restriction to this real protection domain.Thereby some nonessential improvement of having done according to above-mentioned the utility model content of person skilled in art and adjust the example that also should belong to the utility model protection domain.
As shown in Figure 1, intelligent wireless supervision of power consumption of the present utility model system comprises DSP (digital signal processor) control system, note and conversation module, recording system, signal acquiring system, storer, man-machine interface and service end.
Functions such as (1) man-machine interface is used for the setting of system audit end parameter, and the inquiry of fault parameter, and whether each intermodule work of system is normal, and show relevant information.Man-machine interface mainly adopts 12864 lattice lcd as the display part, and the main control chip of liquid crystal is 7920, and this liquid crystal carries Chinese word library, and program writes easily.Button mainly contains six, function is respectively upwards, downwards, left, to the right, determine, cancellation.
(4) as shown in Figure 2, signal acquisition module mainly contains following a few part and forms: 1. voltage transformer (VT), because primary side is a high-pressure section, so big voltage signal must be converted to small-signal.2. wave filter in order to prevent entering of high-frequency signal, causes the error of system, before sampling holder, has added the function of low-pass filter.3. sampling holder keeps sampled data.4. AD converter behind the signal process sampling holder, is sent into AD converter, is digital signal with analog signal conversion.Send into dsp system at last, carry out computational analysis.Signal acquiring system of the present utility model by the voltage signal of voltage transformer (VT) collection high pressure user segment, through wave filter, sampling holder, again through AD converter, is that digital signal is for the dsp system analysis with analog signal conversion.
