GAS METER INTELLIGENT CONTROLLER AND FIRMWARE UPGRADE START-UP METHOD THEREFOR

摘要

A gas meter intelligent controller, comprising a casing (1), an output device (2), and an MCU (3), an accumulator (4), a CPLD (5), a flash memory module (6) and a communication module (7) that are provided in the casing; the accumulator, the CPLD, the communication module and the output device are connected to the MCU; and the flash memory module is connected to the MCU. Also provided is a firmware upgrade start-up method for a gas meter intelligent controller. By means of configuring the cooperation between main and standby start-up partitions and the CPLD, MCU firmware may be safely upgraded, which may greatly reduce the high risk of firmware upgrades for household intelligent gas meters.
