In the present invention, after the battery G is discharged, the external 12V power charger plug can be inserted into the charging socket CZ to charge the battery G.

As shown in FIG. 3, in the photoelectric switch U1, the front baffle, the battery G, the time circuit and the wireless transmission circuit: the present invention is used in combination with the existing mature remote switch control technology of the computer. The computer is set up. During subsequent use, the user can remotely use another computer to control the on-off status of the home computer and the working status of the home computer; before leaving the home, plug the home computer power plug into the indoor power outlet, and the computer is in standby In the state, insert the power plug of the home appliance (such as a rice cooker) that needs to be controlled into the jack of the patch panel of the present invention. When the disc door of the computer in the home is not opened, the infrared light emitted by the detection head of the photoelectric switch U1 is blocked by the front baffle. Under the action of the internal circuit of the photoelectric switch U1, pin 3 of the photoelectric switch U1 has no output; when used at the remote end When the user needs to control the home electrical equipment to work, after the home computer is turned on remotely, the remote operation of the home computer's operation interface (such as the use of video playback software storm video, etc.), open the disc compartment door, so the disc compartment The door drives the photoelectric switch U1 to move forward, and the detection head of the photoelectric switch U1 is no longer blocked by the front baffle. The distance between the detection head of the photoelectric switch U1 and the ground is much greater than 30cm. Therefore, under the action of the internal circuit of the photoelectric switch U1, the photoelectric switch U1 The 3-pin output high level enters the positive power input terminal of the relay K1, and the relay K1 must be electrically closed to control the power input terminal and the normally open contact terminal to close; because, the time circuit time controller module finished product U2 is at The electrical state, the positive trigger signal input terminal 3 of the finished U2 of the time controller module is connected to the normally open contact terminal of the relay K1, so at this moment, The trigger signal is input to the finished U2 of the controller module, and its 9-pin output high-level signal for 5 seconds enters the positive power input terminal of the relay K2. Therefore, the relay K2 must be electrically attracted to its control power input terminal and normally open contact terminal. Closed; because the finished product U3 of the wireless transmitting circuit is in the state of power at the moment, the two contacts under the first signal transmitting button SK of the finished product U3 of the wireless transmitting circuit are connected to the input terminal of the control power supply of the relay K2 and the normally open contact terminal, Therefore, within 5 seconds of relay K2 closing its control power input terminal and normally open contact terminal, the first signal transmission button U3 of the finished wireless transmission circuit U3 will connect the two contacts under the SK button (equivalent When the first signal transmission button SK is pressed manually, the finished wireless transmission circuit U3 will transmit the first wireless control signal for the first time. When the remote user needs to control the electrical equipment in the home to no longer work, through the remote operation of the home computer interface, first close the disc compartment door, so the disc compartment door drives the photoelectric switch U1 to move backward, and its detection head is blocked again by the front The board is blocked, so, under the action of the internal circuit of the photoelectric switch U1, the output of pin 3 of the photoelectric switch U1 has no output high level and enters the positive power input terminal of the relay K1 (after the output of pin 3 of the photoelectric switch U1 outputs a high level, as long as its detection head If it is not blocked, it will always output high level), relay K1 loses power and no longer pulls in its control power input terminal and normally open contact terminal to be disconnected, then, the time controller module finished U2 no longer has an input trigger signal, time control There is no output at pin 9 of the output end of the U2 of the finished module; then the remote operator opens the disc compartment door again through the remote operation interface of the home computer, so the disc compartment door again drives the photoelectric switch U1 to move forward, and the probe head is no longer fronted The baffle is blocked. Under the action of the internal circuit of the photoelectric switch U1, pin 3 of the photoelectric switch U1 outputs a high level again and enters the positive power input terminal of the relay K1, and the relay K1 is energized. Close the control power input terminal and the normally open contact terminal to close, the time controller module finished U2 is input the trigger signal again, and its 9 pin outputs a high level signal for 5 seconds again to enter the positive power input terminal of the relay K2, the relay K2 is energized The input end of the control power supply and the normally open contact end are closed, and the finished wireless transmission circuit U3 transmits the first wireless control signal again.

As shown in Figure 4, in the wireless receiving circuit and control relay, when the remote user needs to control the home appliances at home, by remotely operating the home computer, the finished wireless transmission circuit U3 emits the first first wireless control signal, wireless After receiving the signal from the finished product U5 of the receiving circuit, the first output terminal 4 pin will output a high level. The output high level enters the base of the NPN transistor Q1 through the voltage limit of the resistor R1, and the NPN transistor Q1 amplifies the high level power. 1. The reverse phase enters the negative power input terminal of the relay K3. Therefore, the relay K3 must be electrically connected to its control power input terminal and the normally open contact terminal to close. Because, one pole of the 220V AC power supply passes through one of the plug-in board CX1 It is connected to the control power input of relay K3, the normally open contact end of relay K3 and the power input end of control relay K4 are connected by wires, and the other incoming line CX2 of the patch panel and the other end of control relay K4 power input are connected by wires to control The two ends of the power input of relay K4 and the two ends of the power output socket CZ1 of the plug-in board are connected by wires, so the relay K3 must be electrically connected to its control power input and normally open contact. After the end of the closed ends CZ1 power outlet power strip, respectively, will be 220V AC power, so the power-controlled appliance plug into the electrical work power outlet power strip CZ1. When the remote user does not need to work at home controlled appliances, by remotely operating the home computer, the wireless transmission circuit product U3 transmits the second first wireless control signal. After the wireless reception circuit product U5 receives the signal, the wireless reception circuit product U5 Under the action of the internal circuit, the first output terminal 4 of the finished wireless receiving circuit U5 will stop outputting high level, so the relay K3 loses power and no longer pulls its control power input terminal and the normally open contact terminal off, then, One end of the power output socket CZ1 of the plug-in board can no longer get 220V AC power, so that the controlled household appliances in the power output socket CZ1 of the plug-in board lose power and no longer work.

As shown in Figure 4, in the control relay K4, the first feedback circuit and the SMS sending module: when the user needs home appliances to work, the related circuit, the power output socket CZ1 of the plug-in board outputs 220V power, and the controlled home appliances are powered on After that, since the two ends of the power input of the control relay K4 and the two ends of the power output socket CZ1 of the plug-in board are connected by wires, the control relay K4 (220V AC relay) will be electrically attracted to its control power input and normally open. The contact end is closed (the input end of the control power supply and the normally closed contact end are open); because at the moment, pins 1 and 2 of the finished U6 of the time controller module are in the powered state, and the finished U6 of the time controller module is in the working state, and the power supply is switched The positive pole 5 of the second power supply output of U4 is connected to the control relay K4 signal input. The control power input is connected via a wire. The normally open contact of the control relay K4 signal output is connected to the 3 pin of the finished U6 of the time controller module, so After the control relay K4 is electrically attracted and its control power input end and normally open contact end are closed, the trigger signal of pin 3 of the finished U6 of the time controller module will be input. Under the action of the internal circuit of the finished U6 of the time controller module, the output terminal 9 of the finished U6 of the time controller module outputs a high level for 5 seconds through the resistor R2 to enter the base of the NPN transistor Q2, and the NPN transistor Q2 will be high. Level power amplification and phase inversion are input to the signal input terminal X of the short message sending module U8. Therefore, under the action of the internal circuit of the short message sending module U8, the short message sending module U8 will send a short message to the remote user in real time, the content is "home appliance control "Success", in this way, if the user receives a text message after remote operation, it means that the remote control of the home appliance is successful. If the user does not receive a message after remote operation, it means that the remote control of the home appliance is unsuccessful, and the operation can be performed again. To ensure the reliability of remote control appliances work.

As shown in Figure 4, in the control relay, the second feedback circuit and the SMS sending module: when the user does not need home appliances to work, the related circuit, the power output socket CZ1 of the plug-in board no longer outputs 220V power, and the controlled home appliances lose After the power is no longer working, because the two ends of the power input of the control relay K4 and the two ends of the power output socket CZ1 of the plug-in board are connected via wires, the control relay K4 (220V AC relay) will lose power and no longer control its control The power input terminal and the normally closed contact terminal are closed (the control power input terminal and the normally open contact terminal are disconnected); because at the moment, pins 1 and 2 of the finished time controller module U7 are in the powered state, and the finished time controller module U7 In the working state, the positive pole 5 of the second power supply output terminal of the switching power supply U4 is connected to the control relay K4 signal input terminal. The control power input terminal is connected by a wire, and the control relay K4 signal output terminal normally closed contact terminal and the time controller module finished U7 Pin 3 is connected, so that when the control relay K4 loses power, it no longer pulls in its control power input and the normally closed contact end, the 3 pin of the finished U7 time controller module will be The trigger signal is input, and then, under the action of the internal circuit of the finished U7 of the time controller module, the output terminal 9 of the finished U7 of the time controller module outputs a high level for 5 seconds to step down through the resistor R3 and enter the base of the NPN transistor Q3. The NPN transistor Q3 inputs high-level power amplification and inversion to the signal input terminal X of the short message sending module U8. Therefore, under the action of the internal circuit of the short message sending module U8, the short message sending module U8 will send a short message to the remote user in real time. The content is "successful home appliance control", so if the user receives a text message after remote operation, it means that the remote control of the home appliance is successful. If the user does not receive a text message after the remote operation, it means that the remote control of the home appliance is unsuccessful. Carry out the operation, thereby ensuring the reliability of the remote control of home appliances.
