It Features
1:The system adapts ultra low power MCU as microcontroller,to ensure stability under low power and strong anti-magnetic interference capability, the developer optimizes the design of hardware and software.
2:The host computer system is used to open an account for IC card users, recharge, post-registered card，set system parameter, print bill, and so on. It is reliable, powerful,and simple to use.
3:To ensure whole system running safely and reliably, the system can implement real-time monitoring of the possible exceptions, such as gas leakage and magnetic interference,
4:When the exceptions occurs or the consumption reaches a preset value, the system will immediately save the system parameters and history data for last 12 months. To ensure the security of data , an backup is necessary to avoid data loss.
