Title
(EN) Gas meter intelligent controller and firmware updating and starting method thereof
(ZH) 燃气表智能控制器及其固件升级启动方法
Abstract
(EN)
The invention provides a gas meter intelligent controller and a firmware updating and starting method thereof. The gas meter intelligent controller comprises a shell body, an output device, an MCU, anaccumulator, a CPLD, a flash memory module and a communication module, wherein the MCU, the accumulator, the CPLD, the flash memory module and the communication module are arranged in the shell body;the accumulator, the CPLD, the communication module and the output device are connected with the MCU; and the flash memory module is connected with the MCU. According to the gas meter intelligent controller and the firmware updating and starting method thereof, MCU firmware is safely updated through arrangement of coordinating of an active-standby boot partition and the CPLD, and high risks of firmware updating of domestic intelligent gas meters can be greatly reduced.
