Description

The electric power energy-saving watch-dog

Technical field

The utility model relates to a kind of watch-dog, particularly a kind of watch-dog for the economize on electricity field.

Background technology

In today that energy day is becoming tight, energy-conservationly become people's a important subject.As a kind of important energy, electric energy has obtained using widely in industrial and agricultural production and daily life.That electric energy has is easy to use, the feature of cleaning, but simultaneously in use also than the loss that is easier to produce the energy.People have adopted a variety of modes to control the loss of electric energy, comprise the conveying from power supply, and to the energy-efficient performance of electrical equipment itself, various power save modes have arrived certain energy-saving effect.But along with the raising of people's living standard and the quickening of national urbanization process, household electrical appliance enter family in a large number, and the power consumption of household electrical appliance raises year by year, and peak times of power consumption, power department has to adopt the mode of power cuts to limit consumption to adjust the distribution of power consumption.The energy-saving consumption-reducing of the conveying of power supply and electrical equipment itself is limited, how by Real Time Monitoring another important means that to carry out rational energy distribution between power supply and electrical equipment be saves energy.

The utility model content

The utility model aims to provide a kind of electric power energy-saving watch-dog.By electrical equipment relevant electrical energy parameter is in use realized that real-time digitization shows, and realize economizing on electricity by technical measures such as filtering, compensation.

The technical solution of the utility model is as follows:

The electric power energy-saving watch-dog, it is characterized in that: comprise data processing and control module, also comprise respectively and process the human-computer interaction module that is connected with control module, switching value input/output module with data, the analog input module, hardware times frequency module and remotely controlling computer; Be respectively arranged with communication interface in described data processing and the control module, system module, power module, DSP nuclear, memory cell and external bus.

Wherein data are processed with the processor of control module and are selected the TMS320LF2407A processor.

Good effect of the present utility model is:

The utility model is by measuring and analyze the main power quality parameter of electrical network, especially mains by harmonics parameter, for example harmonic current and voltage, adopt the measures such as rational filtering, compensation that the distribution system with electric unit is adjusted, thereby effectively avoid because of the problems such as harmonic excess on a series of impacts that equipment, instrument, distribution system with electric unit cause, reduced therefore and the electric energy loss that produces and maintenance of equipment, maintenance cost.

Native system advanced person's networking design realizes fully sharing of data resource, can carry out Long-distance Control, has improved level monitoring and efficient, has effectively reduced because the energy loss that the problems such as harmonic excess are brought really realizes energy-conservation, economize on electricity.

The utility model can be widely used in the users such as power department and industrial and mining enterprises, in order to monitor the quality of power supply situation of electric power system.After electrical network breaks down, can by the fault data of instrument record, fix a breakdown as early as possible.Also can be take monitor data as foundation, carry out energy-conservation and technological transformation to what there was power quality problem in some with electric unit, reduce unnecessary energy waste.
