At an enterprise or factories and miness with in the middle of electrical measuring systems, there is no the equipment directly circuit being carried out to loss measurement at present, main cause is distant between 2 that measure; For the measurement of transformer loss because need the electricity of the both sides gathering different electric pressure, have difficulties to a certain extent, the product that on market, other producers develop all takes the on high-tension side voltage of theory calculate, the mode of electric current is measured, there is certain error in this kind of mode, can not reflect the loss situation of transformer exactly.

Power line carrier communication is the communication of power system of the transmission medium taking transmission line of electricity as carrier signal.Because transmission line of electricity possesses very firmly supporting construction, and set up the conductor (generally having three-phase good conductor and one or two aerial earth wire) of more than 3, so while power transmission line conveying power current, the transmission carrier signal of use, not only economy but also very reliable.This comprehensive utilization becomes the peculiar means of communication that all power departments in the world preferentially adopt already.

Along with the fast development of Mobile solution terminal device such as Pad, smart mobile phone etc., the Mobile solution terminal device of various operating system is day by day universal, existing mobile terminal resource such as Pad, the smart mobile phone etc. how made full use of in client's hand realizes the partial function in power consumption remote measurement process, is significant.

Utility model content

The utility model aims to provide a kind of novel electric power loss measurement device, the loss instantaneous value of what this measurement device obtained is not circuit, transformer or miscellaneous equipment, but the power consumption value in certain period, effectively prevent the error result of the measurement that Time Inconsistency causes when testing, and when power consumption rate exceedes predetermined threshold value, designated user mobile phone can be notified in time.

To achieve these goals, the utility model adopts following technical scheme:

A kind of novel electric power loss measurement device, comprise circuit under test, be located at the measurement module in circuit under test at least two, each measurement module connects a line of electric force PLC modulator-demodular unit respectively, each line of electric force PLC modulator-demodular unit accesses electric power network respectively, and is electrically connected with host computer by line of electric force PLC modulator-demodular unit; Host computer is electrically connected with voice unit and gsm communication module respectively.

Further, measurement module comprises CPU processor, measures acquisition module, time module, power module and human-computer interaction module, the output terminal of measurement acquisition module, the output terminal of time module, the output terminal of power module are electrically connected with CPU processor respectively, and human-computer interaction module is electrically connected with CPU processor is two-way.

The beneficial effects of the utility model are:

1, easy to use, what obtained by this measurement device is not the loss instantaneous value of circuit, transformer or miscellaneous equipment, but the power consumption value in certain period, effectively prevent the error result of the measurement that Time Inconsistency causes when testing;

2, when power consumption rate exceedes predetermined threshold value, the form by voice is directly notified designated user mobile phone, user can understand the proportion of goods damageds in time and to exceed standard situation;

3, cost is low: this technology directly utilizes existing distribution network as transmission line, need not additionally connect up, and greatly reduces the investment of network, reduces cost;

4, scope is wide: line of electric force is the network that coverage is the widest, and its scale is that other any networks are incomparable;

5, convenient: as long as the controller of equipment is connected in any supply socket, just can have the express network that PLC brings immediately.
