Method, device and system for realizing reset control

Abstract

The invention discloses a method and a device for power down reset control. The device for the power down reset control comprises a power supply circuit, an interference isolating circuit, a reset signal generation circuit and a control signal output circuit, wherein the power supply circuit is used for supplying a power supply to the device; the interference isolating circuit is used for realizing the interference isolation between a control circuit and the reset signal generation circuit; the reset signal generation circuit is used for generating a reset signal; and the control signal output circuit is used for outputting a reset control signal of the power supply of a product. The method for the power down reset control comprises the following steps of: inputting a monitoring end control signal; performing interference isolation on the monitoring end control signal and triggering the monitoring end control signal to generate a power down reset signal; and converting the power down reset signal, and outputting the reset control signal of the power supply of the product to realize automatic power down reset of the product. The method and the device realize pure hardware reset and self repair of the product in a control mode, and realize the automation of the operating process.

Description

technical field [0001] The invention relates to electronic technology, in particular to a method, device and system for realizing reset control. Background technique [0002] Current communication products are realized by both hardware and software. Due to the emphasis on high-quality requirements for hardware functionality, safety, stability, and maintainability during the product design and development process, the probability of hardware failure after mass production is lower than that of software. Due to the characteristics of the software itself, there are always unresolved problems in the development and design of the software, and the maintenance and upgrading of the software will also introduce new problems. Therefore, the product needs a measure to enable it to perform self-healing when an error occurs during runtime, and return to the original best state after initialization. [0003] For this problem, if an error occurs during operation of the product, the prior...

AI Technical Summary

Problems solved by technology

[0006] In the above-mentioned first operation error solution, the reset signal is given by the main control CPU (central processing unit), and the reset time is uncontrollable; the product maintains power supply during the reset process, and a pure hardware reset cannot be realized; the operating state of the product after reset Abnormal, need multiple reset operations

[0007] In the above-mentioned second solution about operating errors, the reset operation is completed by the operator, which requires increased labor costs; the timeliness of error handling is not enough; due to the different structures and functions of different products, it is difficult to implement in some products; Meet the development requirements of remote control and automatic control in the industry
