Accompanying drawing 3 is the work flowchart of the utility model receiving plate.

Detailed ways

As shown in Figure 1, the general-purpose remote control switch includes a power module, a remote controller, and a receiving board. The remote controller includes a keyboard module with 4*4 matrix keys, a single-chip microcomputer, and a wireless transmission module. The output of the keyboard module is connected to the input of the single-chip microcomputer. The output end is connected to the wireless sending module; the receiving board includes a wireless receiving module, a single-chip microcomputer and a relay control module. The wireless sending module wirelessly transmits the remote control signal to the corresponding wireless receiving module. Connect the relay control module; the clock and reset module are integrated inside the microcontroller. The relay control module is connected with the electrical appliances, and is used to switch on or off the power of the electrical appliances or the power of the bus.

Describe the control method of the present utility model in conjunction with Fig. 1, Fig. 2 and Fig. 3, the control method of universal type remote switch, comprises the steps:

1. As shown in Figure 2, the MCU scans the keyboard in a loop;

2. Once it is detected that a key is pressed on the keyboard, the key value of the key will be returned, and then the code corresponding to the key will be sent out through the wireless sending module;

3. As shown in Figure 3, the wireless receiving module receives the encoded information;

4. The EEPROM integrated in the microcontroller reads the code information, and then performs code comparison;

5. If the received code is consistent with its own stored code, reverse the switch state.

In summary, it is only a preferred embodiment of the present utility model, and is not used to limit the scope of the utility model implementation. All the shapes, structures, features and spirits described in the scope of the claims of the utility model are equal. Changes and modifications should be included in the scope of the claims of the present utility model.
