Description

A kind of multifunction energy-saving control module

Technical field

The utility model relates to a kind of multifunction energy-saving control module, belongs to the single-chip microcomputer automation field.

Background technology

Along with various electrical equipment are universal day by day, bring more and more whiles easily for people's live and work, also cause electric power to supply, need contradiction to become increasingly conspicuous, many local electricities department has to take margining electric method to guarantee the safety of whole electrical network to some enterprises and institutions or residential quarters, has caused many economic losses also for thus country, enterprises and institutions and individual.

Though the electric power supply breach is huge, but our many electrical equipment are the valuable electric power resource of a large amount of wastes when standby but, as: air-conditioning, televisor, home theater, computer etc. all are the standby power consumption rich anies influential family, sohu.com once delivered one piece on June 6th, 2006 and had been entitled as the report of " 1 year power saving 100,000,000 degree of standby man's plug are pulled out in full Beijing ", and how serious visible existing electric appliance standby state have to waste of power resources.

There are company or individual also to propose some energy-saving schemes, also reached good energy-saving effect when bringing convenience to people's life, but these schemes also have many incomplete places, as:

Number of patent application is the household electrical appliance standby energy-saving device of " 200410025237.1 ", though can reach purpose of energy saving, this energy-saving appliance can all have response to the ultra-red order of any Infrared remote controller emission.Suppose just parlor air-conditioning of standby energy-saving device control, and air-conditioning is in outage (energy-conservation) state, at this moment no matter standby energy-saving device receives still DVD telecommand of TV remote-control instruction, standby energy-saving device is conducting immediately once (that is: air-conditioning can be energized once) all, but, air-conditioning can not start because receiving the start-up command of supporting telepilot emission, less standby current can not allow relay keep attracting state, so electricity-saving appliance will cut off the air-conditioning power supply automatically in the very short time, ceaselessly launching infrared remote control instruction air-conditioning will ceaselessly switch on, outage, though conduction time is very short can not waste too many electric energy, but frequent is logical, the outage dash current can seriously shorten the life-span of energy-saving appliance repeat circuit and air-conditioning, also can cause the short circuit of air-conditioning internal electronic element when serious, blast and initiation fire accident etc.Another deficiency of this scheme is; Owing to come the relay or the automatic cutout relay of self-locking conducting by load current, just after the loaded work piece electric current is greater than certain value, relay is kept conducting state, relay automatic cutout after the loaded work piece electric current is less than certain value, but in actual the use might controlled electrical equipment be a miniwatt electrical equipment, can't reach the minimum current of relay self-locking at all, standby current that also might controlled electrical equipment is greater than the threshold current of relay automatic cutout, and can automatic cutout promptly reach purpose of energy saving.

Summary of the invention

The purpose of this utility model is to provide a kind of infrared coding instruction of emission that can other telepilots of work-place study also can solidify one group or several groups of infrared codings instructions in advance in single-chip microcomputer, and can be automatically infrared coding transmitting instructions work-place study or that solidify be in advance gone out and initiatively open or initiatively close controlled electrical equipment, and have under-voltage, overvoltage, energy-saving control module that overcurrent cuts off functions such as controlled appliances power source, timing start-up, timing shutdown, manually start, manual shutdown, environment measuring, telecommunication automatically.

The technical scheme that the utility model is taked is: mainly by single-chip microcomputer and peripheral cell circuit: infrared receiver, infrared emission unit, voltage sampling unit, current sampling unit, environmental detection unit, load switch unit, hummer unit, action button, liquid crystal display, telecommunication unit, and power circuit compositions such as (comprising: reduction voltage circuit, low pressure mu balanced circuit, back-up source rechargeable battery, back-up source charging circuit).
