Description

Digital link switch system

Technical field

The present invention relates to the indoor wall key control switch, and the street lamp lamp light control system, be specifically related to a kind of digital link switch system of new structure.

Background technology

Along with improving constantly of people's living standard, living space has had very big change.Especially the general area of newly-built house is all at 100-180 square metre, villa or united villa even reach more than 200 square metres; And the room is humanized according to sectorization.The increase of living space and each room functions perfect certainly will increase the quantity of lamp decoration/appliance switch.People have to walk up and down in doors in order to control the lighting switch in each room at present, have so not only brought inconvenience to people, have also increased the cost that switch is installed; So people adopt a lamp to control the solution foregoing problems jointly by a plurality of switches of diverse location, but must roll up the quantity of electric wire and switch, and lamp two places control can only be realized, the cross complaint between all switches and the switch can not be solved at all; And existing backguy all directly is connected with live wire with push-button switch, obviously has the hidden danger of getting an electric shock when switch makes moist; Turn off the light if certain is forgotten, might be one day all in electricity consumption.Therefore, people press for the convenient control in energy multichannel many places, safety-type control and energy-conservation switch.

In addition, also there are a lot of weak points present street lamp light control aspect, present control system is by control relation, remove switch power supply, in open and close and the required electric wire of operating state indication is six roots of sensation line at least, is 60 the tunnel such as the street lamp that will control, and the control cabinet of Master Control Room must have 360 connecting lines, therefore the volume of control cabinet is huger, and brings very big workload to installation.

Summary of the invention

At the prior art above shortcomings, the purpose of this invention is to provide a kind of can control and circuit simple numerical link switch system the multichannel many places.

The object of the present invention is achieved like this: digital link switch system, to form by a main controller and at least two keypads, and each keypad is parallel on the 20P data wire that main controller exports; Each keypad is respectively equipped with the control termination/mouth that is connected with electrical equipment/light fixture; Described main controller comprises the 12V/DC transformer, and its input termination/mouth connects power supply, exports to the switch key plate through the 20P data wire;

Described keypad is made up of shell, button, indicator light and core switching etc., each switch key series LED indicator light, and by the 10PS soft arranging wire connect core switching successively, 3083 smooth lotus roots drive BT163 ghyristor circuit and power supplys; Each keypad has the output of four road live wires; It is output as 20P data wire splicing ear; Described keypad divides two kinds of a passage and four-ways.

Main controller also can have been set up remote control circuit, and is user-friendly.

Compared to existing technology, the present invention has following advantage:

Control is convenient: the cross complaint of switch and switch is good, can conveniently show, control the operating state of each road electrical equipment electric light on the keypad, and has one's own department or unit switch and lock function key, promptly presses the control that this bit switch behind the locking key is not subjected to other position switch; It is luminous that switch key also has automatic induction noctilucence simultaneously, is convenient to like this not have night under the situation of turning on light, and can know the position of switch accurately, and distinguish the light fixture of required unlatching;

Safe in utilization: product is divided into main controller and keypad two parts, and keypad provides power supply by 12V safety low tension, adopts low tension control forceful electric power, contactless spark when powering, open, closing electrical equipment or lamp power, and child old man uses does not have the danger of electric shock; And switch has moisture resistance, non-oxidizability, long service life, be present switch life 3-5 doubly;

Automatically reset: behind the grid power blackout, switch can automatically reset and all cut off the power supply; Secondary is connected the power supply of electrical equipment, light fixture and must be opened again, removes the trouble and worry that has a power failure and go out from;

Total disconnected control: keypad is provided with the general reset key that connects each electrical equipment, light fixture, realizes a key master control; The general reset key is by the state of indicator light indication on-off;

Circuit is simple, install and maintenance convenient: switch adopts the pressure in parallel of pressure seated connection mouth data wire to be connected labor and material saving, easy for installation; Fault is judged easily during maintenance, and it is dangerous to change device oncontacting electricity, and except that switch power supply, but the open and close of every bit switch and operating state demonstration only need a tiny data wire just can realize function; Simultaneously also have a phone input port on the main controller of product, as long as the phone incoming line is connected, promptly tool patches the function that Telephone set is called, and so just can remove former each room trouble of socket of having a telephone installed that all will connect up from.

Multiple functional: different according to use occasion and customer group, can design the product of high, medium and low three kinds of specifications.As metal switch panel, liquid crystal touch screen switch panel, and subsidiary liquid crystal touch screen remote control or inductive switch etc.

Product of the present invention can be widely used in many places and street lamp centralized control and industrial automation centralized control such as family, hotel, hotel, office, factory, workshop.
