Abstract: For difficulty of monitoring of energy consumption of crane by use of wired transmission, a hardware and software design scheme of Sink node of perception system of energy consumption for mine crane based on wireless sensor network were proposed. The node uses wireless radio frequency chip CC2530 to realize acquisition and wireless transmission of working parameters of the crane, uses Ethernet controller ENC28J60 to convert received sample data into Ethernet data packet, then uploads it to background monitoring center. Transplantation of uIP protocol stack in CC2530 chip and compiling of performance functions of the Sink node were described in details based on analysis of data communication flow and features of the uIP protocol stack. The test result verifies that the design scheme can realize transmission of TCP data packet accurately and meet requirement of data transmission of the perception system of energy consumption for mine crane.
