Embodiment

As shown in Figure 1, present embodiment comprises button and status display circuit, infrared radiation receiving circuit, RF radio transmitter, RF wireless receiving circuit, data-carrier store, single-chip microcomputer, light fixture energising executive circuit, the communication interface that is used to manage concentratedly and clock circuit; Above-mentioned each circuit all links to each other with corresponding I/O mouth on the single-chip microcomputer; Analyze according to the received signal of button, infrared radiation receiving circuit or the received signal of RF wireless receiving circuit by single-chip microcomputer, control the light fixture of this switch and give other switches information announcement or control the light fixture of other switches and give other switches information announcement, wait to receive that changing state corresponding on this switch behind the execution result of respective switch shows by the RF radio transmitter by the RF radio transmitter.Communication interface links to each other with single-chip microcomputer through the RS485 bus, can realize networking and carry out Centralized Monitoring, management; Clock circuit is setting-up time table timing controlled light fixture arbitrarily.

As shown in Figure 2, button has nine remote keying SW1-SW9 and the manual button SW10 in one's own department or unit, and home key is to be used for the convenient control light fixture that this switch connected.Nine light fixtures that corresponding this group wireless remote control of remote keying light switch is connected comprising the remote keying of this bit switch, that is to say nine light fixtures of one group of wireless remote control light switch may command.Ten the LED 1-LED11s corresponding with button are used for showing the state of each light fixture of this group, and led designs is at the key position place, and the state of the light fixture that can be controlled each wireless remote control light switch comes into plain view like this.

It is little process chip U1 of 89C51 that single-chip microcomputer adopts model.Infrared radiation receiving circuit employing model is that the infrared receiving module U2 of IRM-8061V receives, and needs to use supporting Infrared remote controller carry out remote control to it, after switch receives infrared signal, by the infrared receiving module decoding, inserts the INT1 pin of single-chip microcomputer.The RF radio transmitter is that RF wireless-modulated chip U3, capacitor C 16, the C17 of GW-T5 constitutes by model mainly, sends information to other switches, transmits from the txd pin of single-chip microcomputer.The RF wireless receiving circuit is that RF wireless demodulation chip U4, capacitor C 13, C14 and inductance L 3, the L4 of GW-R5 constitutes by model mainly, is used to receive the information that other switches send, and acknowledge(ment) signal is directly received the INT0 pin of single-chip microcomputer.It is the storage chip U5 of ST24W02M1 that data-carrier store adopts model, and this storage chip uses an I ²The C bus is come the relevant parameter of memory switch, the information of dispatching from the factory that comprises product, the group control information of switch, the self-defined information at button one's own department or unit guarantees that original self-defined information is retained in outage, and uses this information to reconfigure switch after re-powering, to guarantee that the user uses continuously, its PIN6 pin is clock clk, and the PIN5 pin is data line dio, uses the communication of standard iic bus protocol.

As shown in Figure 3, light fixture energising executive circuit mainly is made up of optocoupler U6 and controllable silicon TR1, by the a1 pin output control signal of single-chip microcomputer, light fixture is closed or is opened control by controllable silicon, thereby realize the function of regular tap.

The principle of work of above-mentioned single-chip microcomputer is exactly to analyze and the control light fixture according to the instruction of button, infrared remote controller or RF wireless receiving module, its course of work in two kinds of situation, promptly local master control and strange land remote control.Local master control (as button or infrared remote-controlled signal) process, single-chip microcomputer decision instruction are the light fixture of this switch of control or the light fixture of other switches.If the former then single-chip microcomputer according to the instruction by controllable silicon light fixture is controlled, then and by the RF wireless transmitter module state change message of this switch is announced to other switches; If the latter then single-chip microcomputer give other switches instruction announcement by the RF wireless transmitter module, and wait to receive that the state of the state change message change of respective switch shows.The process of strange land remote control (receiving control signal by wireless network), if this information is the state change message of other switches, single-chip microcomputer then refreshes the demonstration of the state of this switch.If this information is steering order, the single-chip microcomputer decision instruction is the light fixture of this switch of control or the light fixture of other switches.If the former then single-chip microcomputer according to the instruction by controllable silicon light fixture is controlled, then and by the RF wireless transmitter module state change message of this switch is announced to other switches; If the latter then waits for a period of time as not receiving the state change message of respective switch, single-chip microcomputer is given other switches this instruction announcement by the RF wireless transmitter module, this plays the effect of network relay, reduces the wireless blind area of RF and improves the distance of RF wireless telecommunications.

As by certain the switch B in the switch A Control Network, and the B corresponding button is SW1, and the concrete operations and the course of work are such.Press the button SW1 on the switch A, the built-in single-chip microcomputer of switch A receives key information, judge it is to control that lamp at once, and form control information by wireless transport module communication, promptly send out relevant control information and give each switch of network internal, light or close the LD1 that local switch A goes up the corresponding light fixture of controlling simultaneously.After Be Controlled switch B (being that LD1 is pairing) receives the communication information by the wireless reception module, information is carried out verification, the operation that verification is opened or closed self light fixture of controlling by the back, and the pilot lamp of lighting or closing corresponding own position on self panel, return controlled successful information simultaneously and give other each lamps of switch A and network internal.Network internal (except the controlled switch B) is by after being subjected to controlled successful information, to the operation of on self panel the pilot lamp of inductive switch B being lighted accordingly or closing.After switch A received the controlled successful information that switch B returns, to the operation of on self panel the pilot lamp of inductive switch B being lighted accordingly or closing, this control was finished.Under special situation,, will repeat control by above not step and attempt if after switch A does not receive the controlled successful information that switch B returns.Control and successfully just finish this operation.After repeatedly repeating to control the trial failure, switch A stops communication, and the recovering state that the correspondence on the panel is designated as is arrived the state of controlling before failing, and promptly keeps original state behind the communication failure.
