Embodiment Construction

[0022] Various preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] The reset method of the present invention for preventing the system from crashing and interrupting the service through the cooperation of software and hardware adopts a combination of software reset and hardware reset, and can generate different reset actions according to the abnormal situation, so as to achieve the impact on the system and business minimum.

[0024] The reset in the method of the present invention is divided into two categories: hardware reset and software reset, wherein the software reset only resets the CPU part, and does not operate the chip of the business part, so that there is no interruption to the business. Hardware reset is to reset all the chips on the board that can perform the reset operation, which is commonly referred to as the whole board reset. At this time, the service will be interrupted and ...

Abstract

The invention discloses a reset method for preventing system from halting and interrupting services by software and hardware cooperation, comprising the steps of: selecting software reset or hardware reset on the condition that system is abnormal; for the software reset caused by software, the system only resets the CPU and does not process the service so as to assure the service is not interrupted as software reset; if the system exceeds the preset number of software resets in the preset time, making hardware reset. And the invention largely improves system stability and intelligently processes reset signals on different conditions, improving system reset flexibility and reducing possibility of service interrupt caused by abnormal reset.

Description

technical field [0001] The present invention relates to a method for resetting an electronic device to prevent system crashes by utilizing software and hardware cooperation, and in particular to a reset logic circuit design in the field of communications, which uses software and hardware to cooperate together to prevent system crashes from causing service interruptions. method. Background technique [0002] In the electronic equipment of the prior art, in order to prevent the CPU from running to death or perform reset processing in time when the system is abnormal, reset logic is designed in the system. [0003] For a single board, its general reset logic is simply completed by a reset chip with a watchdog, and the reset of the whole board is controlled by software feeding the dog. This practice is very likely to cause the interruption of the business communication of the entire communication network. If there is no dog feeding signal when the software runs to death, the b...
