Abstract
(EN)
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.

L'invention concerne un contrôleur intelligent de compteur de gaz comprenant un boîtier (1), un dispositif de sortie (2), ainsi qu'une MCU (3), un accumulateur (4), un CPLD (5), un module de mémoire flash (6) et un module de communication (7) situés dans le boîtier; l'accumulateur, le CPLD, le module de communication et le dispositif de sortie sont connectés à la MCU; et le module de mémoire flash est connecté à la MCU. L'invention concerne également un procédé de démarrage de mise à niveau de micrologiciel d'un contrôleur intelligent de compteur de gaz. Grâce à la configuration de la coopération entre des partitions de démarrage principal et de secours et du CPLD, le micrologiciel MCU peut être mis à niveau en toute sécurité, ce qui peut réduire considérablement le risque élevé de mises à niveau de micrologiciel de compteurs de gaz intelligents domestiques.
