Electroless control type energy-saving lamp control switch for guest room of the present invention, the induction type touch switch that mainly is the intelligent lamp control switch that will be forced to withdraw from the market changes no-voltage formula key switch into, achieving no external voltage is the may command light controller, overcome at one stroke the fatal shortcoming that original intelligent lamp control switch has numb hand electric shock feeling sometimes, have and be skillfully constructed, reasonable in design, be in zero-voltage state on the control switch of lamp fully, make device have advantages such as safe as a house, can also design lamp control program according to customer requirements, make it also to have energy-conservation and make things convenient for characteristics such as guest, be particularly suitable for Hotels and Hostels and install and use.

Description of drawings

Accompanying drawing is a kind of electrical block diagram in the embodiments of the invention.

Embodiment

Referring to accompanying drawing, electroless control type energy-saving lamp control switch for guest room of the present invention, its structure comprises the intelligent lamp control switch that encoder U1 and U2, single-chip microcomputer and peripheral circuit thereof and relay J 1-Jn form, wherein, each signal input part D7-D0 of encoder U1 and U2 connects respectively and is connected with the end of shielding conductor with corresponding key K switch 1-Kn respectively behind the resistance R 1-1-R1-n again, and the other end of key switch K1-Kn all is connected with ground wire.In order to improve antijamming capability; prevent misoperation; can be connected with the anti-interference protective circuit of a cover at each signal input part of encoder U1-U2 respectively; the anti-interference protective circuit of every cover is formed by two diode D1, D2 and a resistance R 2; the negative pole that the positive pole of one of them diode D1 connects power cathode, diode connects the signal input part of encoder; the positive source (VCC) that the negative pole of another diode D2 connects, the positive pole of diode connect the code device signal input, and resistance R 2 is connected between the signal input part and power cathode (GND) of encoder.Described encoder U1 and U2 select the 8 lines-3 line priority encoder of CT54148 or models such as CT74148, CT54L148, CC4532 for use, for lamp control switch more after a little while, an available priority encoder, for lamp control switch more for a long time, available two or more priority encoder, other circuit is identical with original intelligent lamp control switch.During work, K switch pushes button, corresponding codes device signal input part is in the moment that is connected with ground wire, its reference voltage discharges over the ground and forms pulse signal, this pulse signal can make encoder action and as the triggering signal of encoder, the output signal of encoder by single-chip microcomputer with its peripheral circuit processing after, make the corresponding relays adhesive, relay switch is connected, and can make the electric light energized that is connected with this switch and is lighted.

This device can have been saved the energy for the hotel under convenient guest's prerequisite, concrete characteristics are as follows:

1, hommization, intellectuality: (1) guest has just moved in and has entered the room and insert the power taking board, only has corridor lamp bright (or night-light is bright) to make in the room to have certain brightness to be convenient to the guest in the guest room to operate other switch. (2) this system main-control switch in bed, touches these all lamps of switch room (comprising toilet lamp) and entirely extinguishes after the guest takes a shower, and needn't allow the guest turn off the light one by one, greatly facilitates the guest. Also make the guest not be subjected to the interference of any light. (3) after the master control switch is turned off the light, get up in the night to urinate for making things convenient for the guest, it is bright that the guest only need touch any one switchboard night-light of the head of a bed, makes the guest conveniently go to the lavatory, can freely open required lamp behind the lavatory. And do not need to open again master switch. Equally, two one of guests have slept earlier, close master control, the lamp sleep of entirely going out. Another guest finishes thing and goes back to the room and can freely open required lamp and needn't go to the head of a bed and open earlier master control. Not only made things convenient for the guest but also avoid bothering another guest.

2, energy-conservation: because the present Based Intelligent Control of this system not in the hotel, general guests are when sleep, toilet lamp opened sleeping, so that WA is convenient at night, even the lamp that some guests connects in the guest room is not related to just sleep, this has just wasted the electric energy in hotel greatly, as has possessed above-mentioned functions, turns off the light and just lifts a finger, we believe that each guests can sleep the lamp Close All, this has just saved the energy in hotel greatly, in addition, and when guests leave the guest room, although have some lamps in the guest room this moment is bright, as long as take out the power taking board, lamp goes out entirely in the guest room, and system returns to original state. When guests enter the guest room again, insert the power taking board, only have this moment corridor lamp and night-light bright, this has not only saved the energy but also make the guest that a kind of comfortable impression be arranged.
