Abstract

Embodiments of the present invention relate to a low-power consumption control device, method, and terminal device for a battery-powered sensor. A delay module enables an AD sampling module to collect second power data and first power data transmitted by sensors before and after a power system failure. The signal triggering module triggers the central processing unit to work so that the central processing unit receives the first power data and the second power data. The reason for the failure of the power system is to avoid that the power data before the power system failure cannot be obtained due to the failure of the power system, only the power data after the power system failure can be obtained, and the failure situation of the power system cannot be accurately analyzed; it solves the problem of existing power system failure, In the case of low power consumption such as light load, the technical problem that the data of the sensor detection power system before the failure cannot be obtained.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a low power consumption control device, method and terminal equipment for battery-powered sensors. Background technique [0002] In the power system, the CT / PT energy harvesting method is used to obtain the voltage and current in the voltage sensor and current sensor. Since the existing sensors cannot achieve low power consumption, the battery energy harvesting cannot be used, and the power consumption of the battery energy harvesting is quite low. Yes, only CT can be used for energy extraction. The CT energy harvesting method has a large volume and is affected by the current of the wire. When the load is light, the sensor will not be able to obtain enough energy, which will cause the sensor to fail to work normally, resulting in the failure of the power system to obtain low voltages such as faults and light loads. Sensor data under power consumption impacts analy...
