DC power supply device used for data acquisition of sensor

Abstract

The invention relates to a DC power supply device used for data acquisition of a sensor. The device comprises a lead-acid battery power supply module, a solar power supply module, a converting circuitmodule, a power supply management module and a master control module, the lead-acid battery power supply module, the solar power supply module and the converting circuit module are all connected withthe power supply management module, the power supply management module, the solar power supply module and the converting circuit module are all connected with the master control module, the converting circuit module is used for converting an electric supply to direct current and inputting the direct current to the power supply management module, the master control module selects one of the lead-acid battery power supply module, the solar power supply module, and the electric supply as input of the power supply management module according to voltage information of a lead-acid power supply of the power supply management module, and the power supply management module preferably selects the lead-acid battery power supply module for power supply of the sensor. According to the device, the structure is simple, the problem of continuous power supply of the sensors in remote regions with severe environment is solved, the solar power supply mode is adopted, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a direct current power supply device for sensor data acquisition. Background technique [0002] The sensor data acquisition system has been widely used in the detection industry; however, the power supply is an indispensable device for these sensor data acquisition systems, and the existing sensor data acquisition systems generally only use a single power supply; When the system is powered on, or powered by a lithium battery, there is no guarantee that the system can work for a long time, which may cause the data to be undetectable, and the correctness of the data may not be guaranteed. [0003] However, in remote areas with harsh environments and without mains power, the sensor data acquisition system becomes a decoration and cannot provide correct acquisition data; therefore, a device that can provide power for different power supply methods is urgently needed To ensure the normal operation of the equipment.
