Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is a contour structures schematic diagram of the present utility model;

Fig. 3 is the schematic diagram that each switch connects with parallel mode in the device;

Fig. 4 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model was produced circuit 7, housing 8, control switch 9 etc. and is formed by central processing circuit 1, infrared radiation receiving circuit 2, communication interface circuit 3, output control circuit 4, power circuit 5, LCD, backlight, touch screen circuitry 6, temperature detection and clock, date.Touch display screen 10 is loaded on the housing 8; By figure lively, vivid on the display screen 10, the operating state of each switch in the display systems; Come each switch is controlled by the pattern on the direct touch display screen 10, also can take place when touching control simultaneously " key sound ".On each liquid crystal pattern, all be furnished with back lighting device, and can control switching backlight by the user; Simultaneously, all free, date of intrasystem each switch and temperature show.

With reference to Fig. 3, each switch 9 connects with parallel mode in the device, each switch all has the address of oneself, all switches closely are connected as a single entity with communication mode, the user can control the switch in every other place by the switch of any old place, and can be reflected on the local LCDs 10 by the switch working state that other are local.Parallel connected mode helps the combination in any of number of switches in the device, and the user can select 1～9 switch of every cover all can as required.

With reference to Fig. 4, central processing circuit 1 comprises integrated circuit U1 (model 8051) and peripheral cell etc.; The function of CPU (U1) mainly comprises the LCD display driver, backlight switch control, touch-screen scanning input, infrared signal decoding, communication coding and decoding, the drive controlling of relay, buzzer and the address that switch sets discerned etc.Infrared receiving circuit 2 is fairly simple, utilize general infrared receiving terminal J2 to infrared signal receive, filtering, amplification, and then signal is delivered to the middle fracture of CPU.Communication interface circuit 3 adopts general differential driving chip 751 76 (U2) to realize the RS485 serial communication, this communication mode long transmission distance, anti-interference ability is strong, and be convenient to and computer and other equipment interfaces, realize programming Control, timing controlled, even be connected with network, phone, realize network control intelligent distant control etc.Output control circuit 4 comprises triode Q1, Q2 relay R J, buzzer BELL and diode D5 etc.; Triode Q1, Q2 are respectively applied for and drive buzzer and relay work, and relay R J is parts of really finishing " switch " task, and buzzer then is in order to send " key sound ": because the drive coil of relay has certain inductance.So be used for back discharge by protection diode D5.Power circuit 5 by transformer T1 from the civil power power taking, through bridge rectifier, filtering, and then carry out powering for the device each several part after the voltage stabilizing with 7805 (U5); Because integrated circuit U4 operating voltage is 3V, so adopted voltage-stabiliser tube Z1; D6 and C9 then are that clock still can walk on for after guaranteeing of short duration power failure.LCD, backlight, touch screen circuitry 6 comprise integrated circuit U3 (model is MC204-1LT), and the LCD among the U3 is responsible for showing with graphics mode the operating state of each switch, also are responsible for information such as read clock, date and temperature simultaneously; Touch-screen then is responsible for allowing user's input command easily, controls the work of whole device.Temperature detection and clock, date produce circuit 7 and mainly are made up of a special chip OKI121D-2 (U4) and peripheral circuit thereof; The function of this special chip is very powerful, is limited to the capacity of display of LCD, and this device has just been realized its some functions commonly used, as clock, date and temperature detection etc.

This installs on each switch all has " total closing " function, and promptly the user only needs just can close all switches by once-through operation.The lock function of adding is all arranged on each switch, and after promptly local switch being locked, switching manipulation all can not be carried out to this switch in other places; And after local switch was operated, this lock can be untied again automatically.After the device power-on-reset, all switches will be " pass " state, and LCD backlight will be " opening " state.
