Title:
HYBRID SUPER PULSE CAPACITOR POWER SUPPLY CIRCUIT OF GAS METER
Document Type and Number:
WIPO Patent Application WO/2024/021892
Kind Code:
A1
Abstract:
Disclosed is a hybrid super pulse capacitor power supply circuit of a gas meter, to solve problems of a low power failure report success rate, presence of many limitations, and poor effect in power failure design of existing gas meter systems. The key point of the technical solution is: comprising a dry battery pack, a motor valve that is powered by the dry battery pack and controls the on/off of fuel gas, a first LDO module that is coupled to the dry battery pack and converts a voltage from 6 V into 3.6 V for output, a current limiting resistor coupled to the first LDO module and configured for current limiting protection, a UPC module coupled to the first LDO module and configured for energy storage and standby power supply, a load switch coupled to the first LDO module and the UPC module, and an NB-IoT module coupled to and controlled by the load switch. The motor valve is coupled to the UPC module to allow standby power supply of the UPC module. The hybrid super pulse capacitor power supply circuit of a gas meter in the present invention has a simple design and low costs, can achieve stable control of valve closing and report communication under various working conditions, and is more stable and safer.
