Single board power control circuit and electronic equipment

Abstract

The application provides a single-board power supply control circuit and electronic equipment, which relate to the technical field of electronic circuits. The single-board power supply control circuit includes a power-off control module, a restart control module, a control signal combination module and a power conversion module, the power-off control module includes a first reset chip and a D flip-flop, and the restart control module includes a second reset chip, The third reset chip and the first output unit, the control signal combination module includes an OR chip and the second output unit, the power-off control module and the restart control module are used to send control to the control signal combination module based on the restart signal sent by the processor The signal and control signal combination module is used to control the power conversion module to perform power failure without restart or restart based on the control signal. The circuit uses the built-in processing function of the single-board system to realize the normal power-on, power-off, and automatic power-on functions of the system after power off, which reduces the circuit complexity and saves hardware design costs and maintenance costs.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular, to a single-board power supply control circuit and electronic equipment. Background technique [0002] With the development of communication technology, the reliability, fault protection capability and maintainability requirements of communication equipment are getting higher and higher, while the design cost requirements are getting lower and lower. As one of the most important components in communication equipment, the single-board power control system is of great help to the maintainability and fault protection of the equipment. [0003] "Power failure alarm" and "power failure automatic restart" are the two most important functions in the single-board power control system. For example, when the system is overheated due to environmental reasons, in order to avoid fire or damage to the subsequent hardware circuit, the system needs to make intelligent judgmen...
