Internet-of-Things gas meter power supply management detection method

Abstract

The invention provides an Internet-of-Things gas meter power supply management detection method. The method comprises the steps: formulating voltage specification requirements; detecting a power supply voltage through AD sampling; under the conditions that the sampling voltage is detected to be inconsistent with a current display voltage level for three consecutive times and the detected samplingvoltages are in another level voltage state, executing voltage switching and starting a corresponding task state machine, reporting a meter state actively by a gas meter under the condition of switching to an under-voltage state, carrying out warning on a background system, informing a user of battery replacement, and making a corresponding error code prompt by a meter end of the gas meter; underthe condition that the gas meter is in communication, starting power supply voltage detection at a set frequency, and increasing a hysteresis voltage design and a high starting voltage value. According to the method, the abnormal condition of the power supply capacity of the power supply can be predicted to the greatest extent and the communication stability of the gas meter is ensured; when the power supply capacity of the power supply is detected to be insufficient in periodic monitoring, an alarm is given in time to remind a user to replace the battery, so that normal gas use of the user isprevented from being influenced.

Description

technical field [0001] The invention is applicable to the intelligent Internet of Things gas meter industry, and relates to a power supply management scheme of a meter terminal power supply system. Background technique [0002] With the development of science and technology, the gas meters used in people's daily life are gradually becoming more technological and intelligent. While the technology is updated, it also brings more convenience to gas companies and users, with more accurate measurement, more timely billing, and on-site Reduced operating requirements, reduced operation and maintenance costs, etc. With the intelligentization of terminal equipment, gas meters are independent terminal equipment. In order to maintain the long life cycle of the equipment, higher requirements are put forward for the power management scheme of the equipment. Therefore, power management needs to be based on battery power supply stability, power consumption, power supply Capacity monitorin...
