The network switch 130 is communicatively connected to the processor module 110, the logic control module 120 and the Ethernet interface circuit 260, and is used for three-party communication between the processor module 110, the logic control module 120 and the Ethernet interface circuit 260. The data processing capability of the logic control module 120 can be called to improve the efficiency of Ethernet communication.

[0027] To match various data processing requirements, in this embodiment, the processor module 110 includes a main processor 111, and a data processor DSP, a flash memory FLASH and a random access memory RAM that are communicatively connected to the main processor 111. The data processor DSP is also communicatively connected to the logic control module 120.

[0028] The logic control module 120 recognizes that the various data received can be converted into real-world signals such as audio, video, pressure, temperature and position through the data processor DSP, and then quickly performs various operations such as addition, subtraction, multiplication and division. The data processor DSP then converts the information after the operation into digital signals and transmits them to the main processor 111 for further data analysis and other processing.

[0029] Flash memory FLASH can be used to store various data processing software programs to adapt to various data processing and analysis needs and ensure data processing efficiency.

[0030] In a specific example, the main processor can be selected as an AT91SAM9G45 microprocessor, which can be connected to the logic control module 120 through the MII bus, UART bus, BUS bus, and DSP bus, and can be connected to the network switch 130 through the MII bus and SPI bus.
