Power supply control method, device and system for managing and ensuring smooth communication

Abstract

The invention provides a power supply control method, device and system capable of managing and guaranteeing communication smoothness. The system at least comprises an intelligent power source and an upper computer; in a power supply state, the upper computer is used for sending a collection instruction to the intelligent power source and re-sending the collection instruction after power supply state feedback which is sent out by the intelligent power source is received, the intelligent power source is used for judging whether lasting time when the collection instruction is not received reaches preset delay time or not; if the collection instruction is received when the lasting time does not reach the preset delay time, the collection response is responded after the collection instruction is received, and a power supply state of the intelligent power source is fed back to the upper computer; when the lasting time reaches the preset delay time, power-off resetting control of power-off first and power-on second is performed on transmission equipment.

Description

technical field [0001] The invention relates to data transmission equipment, in particular to a power supply control method, device and system for managing and ensuring smooth communication. Background technique [0002] The intermediate transmission equipment for network transmission refers to the intermediate equipment used to transmit network data such as video streams and audio streams. It is usually connected to the host computer and equipped with an independent power supply. [0003] Video monitoring equipment such as highways and safe cities are installed and operated outdoors, and the data needs to be uploaded to the monitoring management center in real time with the help of transmission equipment. Due to the relatively harsh outdoor environment, the data transmission equipment often crashes, resulting in communication failures and data loss. Affects management security and decision making. Contents of the invention [0004] The technical problem to be solved by t...
