Description

High-grade electronic wall switch

The utility model belongs to a high-grade kind newly developed in the switch on wall field, the electrical appliance power control that is best suited for installing and using in the room.

Present known conventional wall switch, adopt the break-make of manual conductor contact technique control electrical appliance power supply, though it is simple and reliable, but can not carry out straighforward operation, the superior demand that improves day by day with people aspect this installs and uses in being used for the room is incompatible, and the use for the old,weak,sick and disabled person and children also is extremely inconvenient simultaneously.

The purpose of this utility model provides a kind of advanced electronic switch on wall, and it both can manually be controlled, also can remote control control, and also anti-interference, safe and reliable.

The purpose of this utility model is achieved in that at one and is provided with the infrared ray receive window, touch button, the panel of power supply P cock and functional indicator light combines with board box and in the ambroin casing that constitutes, load onto one by remote control infrared signal reception amplification and decoding circuit, the bi-directional thyristor switch circuit, capacity voltage dropping circuit, or/and the electronic control system that silicon diode two-way series reduction voltage circuit is formed, a hand-held remote control reflector, emission modulating-coding infrared pulse signal, electronic control system is carried out remote control, the break-make of control switch circuit, simultaneously, by being contained in the button that touches on the machine shell panel, manually control, thus realize switch on wall can be manually again can remote control purpose.

The circuit of electronic control system comprises two kinds:

First kind of power series formula: i.e. the power supply input wires terminal of electronic control system as the conventional wall switch, is serially connected between the live wire (or zero line) of electrical appliance.It comprises four parts:

1. the remote control infrared signal receives and amplifies and decoding circuit, mainly form with special-purpose decoding integrated circuit LCS and relevant Resistor-Capacitor Unit by special infrared reception amplification module MX, the modulating-coding infrared signal that hand-held remote controller is sent receives, amplification, shaping and decoding, if decode mistake (or noise) signal that successfully promptly really admits a fault, then export a control signal, and be locked in output, simultaneously, decoding integrated circuit also is provided with the manual ringing input, by connecting touch-switch, manually control.In addition, decoding integrated circuit inside also has auto-reset function, and when running into power failure, this device can be automatically with the electrical appliance dump of controlling like this.Owing to adopted special infrared reception amplification and decoding integrated circuit, thereby the utlity model has very high functional reliability.

2. bi-directional thyristor switch circuit is formed by driving triode and bidirectional triode thyristor, with the control signal of decoding circuit output, amplifies through driving triode, forms triggering signal, trigger the bidirectional triode thyristor conducting or end, thereby realization is to the control of electrical appliance.

3. capacity voltage dropping circuit is made up of decompression capacitor, rectifier diode, voltage stabilizing didoe and filter capacitor, and work is kept power supply for control system provides when bidirectional triode thyristor ends.Owing to used capacity voltage dropping circuit, so this device can work online for a long time.

4. silicon diode two-way series reduction voltage circuit composes in series by several silicon diodes are two-way, and this partial circuit is connected with the bi-directional thyristor switch circuit.Owing to utilized silicon diode forward voltage drop value (VF) to stablize constant, be not subjected to the characteristic of circuit voltage variable effect, so, when the bidirectional triode thyristor conducting, can form a stable voltage drop, replace capacity voltage dropping circuit to provide enough DC power supply for control system through rectification.So just realized that this device can be serially connected between the live wire (or zero line) of electrical appliance and normally works, and does not benefit from the influence of appliance power size; Simultaneously, the silicon diode reduction voltage circuit, than reduction voltage circuit such as the resistance or the inductance step-down of alternate manner, power consumption is few, and heating temp is little, long service life.

Second kind of power supply also connects formula: promptly the power supply input wires terminal of electronic control system and output wiring terminal are provided with respectively independently, and therefore, power input directly connects civil power, and output directly connects electrical appliance.This circuit only includes above-mentioned reception amplification and decoding circuit, bi-directional thyristor switch circuit, capacity voltage dropping circuit three parts.

The hand-held remote control transmitter circuit is made up of with relevant Resistor-Capacitor Unit special-purpose remote control coding integrated circuit LC2190, infrared light emitting diode, 6 touch-switchs.Connect any touch-switch, the modulating-coding infrared signal that can to launch corresponding one road carrier frequency be 40KHZ is controlled switch on wall.

Owing to adopted such scheme, make this electronic wall wall switch can remote control, again can be manual, and have very high functional reliability and outage protection and advantage such as easy for installation automatically.
