Real-time bus working state monitoring method and intelligent bus system

Abstract

The invention provides a real-time bus working state monitoring method and an intelligent bus system. The intelligent bus system comprises one or a plurality of intelligent bus connector units which serve as routes with one another and are used for acquiring working state parameters of all busbars, an intelligent control box and a management device, wherein each intelligent bus connector unit transmits the working state parameters acquired by each intelligent bus connector unit to the intelligent control box by selecting a nearest route path; the intelligent control box is used for receiving busbar working state parameters transmitted by the plurality of intelligent bus connector units by using wireless self-networking technology, carrying out protocol conversion on the received busbar working state parameters and then sending the received busbar working state parameters subjected to the protocol conversion to the management device; and the management device is used for monitoring, managing and controlling working states of buses according to the busbar working state parameters. By implementing the method and the system, the technology of monitoring, managing and controlling the working states of the buses through monitoring the working states of the buses in real time and transmitting a monitoring result to a management center in real time is realized.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a system and method for real-time monitoring of the working state of a busbar, which is named an intelligent busbar system. Background technique [0002] In the electric power system, due to long-term operation in the air and the influence of ambient temperature and humidity, the busbar joint nodes will experience thermal expansion and contraction, surface scaling, oxidation or corrosion, resulting in loose contacts, poor contact, and abnormal overheating. In serious cases, it may lead to fire or major safety accidents. Traditional busbars do not have detection and alarm functions. However, the existing intelligent busbar system mainly uses two methods to realize it. Signals are transmitted to the management unit via signal lines running along the busbar. The disadvantage of this wired method is that signal wires need to be laid along the entire busbar, which will damage...

Problems solved by technology

[0002] In the electric power system, due to long-term operation in the air and the influence of ambient temperature and humidity, the busbar joint nodes will experience thermal expansion and contraction, surface scaling, oxidation or corrosion, resulting in loose contacts, poor contact, and abnormal overheating. In serious cases, it may lead to fire or major safety accidents. Traditional busbars do not have detection and alarm functions. However, the existing intelligent busbar system mainly uses two methods to realize it. The signal is transmitted to the management device through the signal line arranged along the busbar

The disadvantage of this wired method is that it is necessary to lay signal lines along the entire busbar, which will damage the electrical characteristics of the busbar and cause potential safety hazards. In addition, when the intelligent busbar system fails, it needs to be powered off for maintenance.

The disadvantage of this wireless method is that: using the point-to-multipoint data transmission method, a large number of relay points need to be arranged to ensure that the data can reach the management device

Once the relay point fails, multiple nodes will be affected, and the stable and reliable operation of the wireless signal cannot be guaranteed
