A low-power IC card gas meter design based on MSP430 series single-chip microcomputer is proposed. The hardware design, electronic control system circuit structure and system software design of the IC card gas meter are discussed. In order to effectively reduce power consumption, the peripheral electronic components are composed of low-voltage, low-frequency, static low-power devices; for the system software, the design is carried out in terms of low power consumption, information security, anti-interference and reliability. The overall power consumption of the system is very low, and the operation is stable and reliable, easy to operate, and has strong anti-interference ability.
