After the transmitter relay is turned on, the transmitter button module connects to the transmitter power supply, at which point the transmitter button module is powered on and can be controlled by its buttons, sending corresponding button signals. These button signals are encoded by the transmitter remote control module and sent to the receiver 2 to achieve control. It should be noted that the remote control method used in this example is an existing control method.

[0021] The transmitter remote control module includes a first antenna, a first high-frequency component, a first decoder, and a first encoder.

If abnormal, the receiver 2 remote control module box transmitter 1 sends a temperature abnormality signal and triggers an alarm on transmitter 1; alternatively, the Bluetooth receiver module sends a temperature abnormality signal to the smart Bluetooth device 3, triggering an alarm on the smart Bluetooth device 3. It should be noted that the temperature measurement module is an existing device, and its processing and judgment methods are also existing methods.

[0026] It should be noted that, in this example, the motor operating parameters collected by the temperature detection module and the current detection module can also be transmitted to the smart Bluetooth device 3 via the Bluetooth receiving module. These parameters include data such as temperature, current, and winch load calculated from the current, and are displayed on the smart Bluetooth device 3 for convenient monitoring of the winch motor's operating status. In some other embodiments, a voltage detection module can also be included.
