Description

technical field [0001] The invention relates to the field of power supply technology, in particular to a power supply control system for a meter wireless communication device. Background technique [0002] The Internet of Things gas meter (or collector) is composed of a traditional base meter (membrane or electronic) or flow meter, combined with a controller with wireless remote transmission function. Through wireless remote transmission technology, functions such as remote transmission and control of meter information can be realized (such as smart meter reading, charging information monitoring, etc.), effectively solving application problems such as difficult door-to-door meter reading and cost maintenance. [0003] Among them, the wireless communication device serves as a data transmission interface between the controller and the base station, and plays a key role in the remote transmission function. Therefore, in order to ensure the normal operation of the wireless remo...
