[0042] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0043] In actual use, the remote control receiver and transmitter communicate via wireless radio frequency (RF), operating in the 433 MHz frequency band. This design offers strong anti-interference capabilities and allows multiple devices to operate simultaneously. Upon powering on, the transmitter automatically scans the frequency to establish communication with the receiver. The receiver analyzes the data from RF module 3, obtains transmitter operating instructions, and transmits them back.

[0044] The RF module 3 using a dedicated RF processing chip is responsible for receiving wireless RF signals in the 433MHz frequency band and performing FSK decoding, and then transmitting them to the RF processor.

[0045] The RF processor uses an automotive-grade 32-bit dedicated processor. Its function is to receive the data transmitted by the RF module, unpack it, convert it into the format of "start flag + packet length + data + checksum", and transmit it to the main controller.

[0046] The main controller uses a 32-bit core processor and communicates with the RF module through SPI. It realizes RS485 communication (free protocol, Modbus master, Modbus slave) through a 485 dedicated chip, and realizes CAN bus communication (free protocol, CanOpen) through a CAN transceiver. The input and output signals are introduced into the main controller MCU for acquisition and control through the isolation amplification protection circuit.

[0047] The output circuit uses an intelligent high-side switch chip with abnormal state protection function, which is responsible for outputting relevant vehicle electronic control signals and controlling the controlled equipment.

[0048] The interface resource data of IO resources and pin definitions are shown in Table 1.

[0053]

[0054]

[0055] IO resources refer to all input, output, communication, power supply and other interfaces controlled by the main controller MCU. The pin positions of the vehicle connector corresponding to IO resources are called pin definitions. IO resources are collected and amplified by the main controller and dedicated chips, and electrically connected to external devices through the vehicle connector. They have good protection and are easy to replace. Connector module 7 consists of two connectors (i.e., connector No. 1 and connector No. 2). Each connector has 3 rows and 8 columns of electrical pins, which are called pins. The controller functions derived from them are called pin definitions. The input, output, communication and other functions referred to by all pins are called "IO resources."

[0056] Among them, AI is analog input, DI is switch input, AO is analog output, DO is switch output, and PWM is proportional pulse width modulation (PWM) output. In addition, Figure 5 GPIO stands for general-purpose input and output pin.

[0057] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
