Abstract

The invention discloses a power supply control system of a field on-line monitoring device. The power supply control system comprises a control unit, a GPRS (General Packet Radio Service) module, a plurality of loads connected in parallel and isolated power supply modules. The GPRS module is connected with the control unit through a first voltage-stabilizing circuit, and receives a control signal of the control unit; the load in each path is provided with a second voltage-stabilizing circuit, and each second voltage-stabilizing circuit is respectively connected with one isolated power supply module, and each isolated power supply module is connected to the control unit, so as to receive the control signal of the control unit; the load connected in parallel of each path is connected to one isolated power supply module, and the isolated power supply module is connected with the control unit so as to receive the control signal of the control unit.

Description

technical field [0001] The invention relates to a power supply system, in particular to a power supply control system of an on-line monitoring device in the field. Background technique [0002] Many electrical equipment in the power system are installed outdoors, and some are even on high-voltage lines. The devices for on-line monitoring of these power equipments are inevitably installed outdoors, so how to conveniently supply power to the on-line monitoring devices is an urgent problem to be solved. [0003] The solar power supply is divided into two parts: charge management and power supply management. The charging management part is mainly responsible for maximizing the use of solar energy to charge the battery, and managing the charging and supply control between the battery packs. The power supply management part is mainly responsible for the power supply control of each data acquisition channel at the front end, so as to achieve the optimal use of power supply and ac...
