Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0038] In the communication system, the main control card (also known as the main control single disk) is the core of the software and hardware of the control station. It coordinates the relationship between software and hardware in the control station and various control tasks. item function. The main control card manages the service control card (also called business single disk) and fan control card (also called fan single disk) of the entire communication system. The main control card can monitor and manage the power supply of other control card...

Abstract

The embodiment of the invention provides a starting control circuit and method. The circuit comprises a first power supply circuit, a processor, a power management component circuit and a restart control circuit, wherein the first power supply circuit is used for supplying power to the processor, the processor is used for receiving a remote restart instruction and outputting a first control signalin response to the restart instruction, the restart instruction is used for indicating the processor to be restarted, the power management component circuit is used for responding to the first control signal and sending a disable signal to the first power supply circuit so that the first power supply circuit stops supplying power to the processor, the restart control circuit is used for sending asecond control signal to the power management component circuit after detecting that the processor is powered off, and the power management component circuit is further used for responding to the second control signal and sending an enable signal to the first power supply circuit so that the first power supply circuit supplies power to the processor again. The circuit is advantaged in that the processor can be restarted after being powered off.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a startup control circuit and method. Background technique [0002] In the communication system, the main control card (also called the main control board) manages the service control card (also called the business board) and the fan control card (also called the fan board) of the entire communication system. The control card is used for power monitoring and management, including restarting after power failure. However, in some special scenarios, the processor on the main control card needs to be powered off and restarted (i.e. cold restart). The traditional cold restart method requires manual operation and requires personnel to operate on site. Contents of the invention [0003] In order to solve related technical problems, an embodiment of the present invention provides a startup control circuit and method. [0004] The technical scheme of the embodiment of the present i...
