Hot backup automatic switching time control system

Abstract

The invention discloses a hot backup automatic switching time control system. The hot backup automatic switching time control system comprises an automatic monitoring terminal used for daily controlling urban lighting time, a middle relay used for switching the control right of an urban lighting circuit between the automatic monitoring terminal and a hot backup automatic switching time control terminal, and the hot backup automatic switching time control terminal used for automatically obtaining the control right of the urban lighting circuit when the automatic monitoring terminal is in faults, and automatically switching the control right of the urban lighting circuit to the automatic monitoring terminal when the faults of the automatic monitoring terminal are removed; the hot backup automatic switching time control terminal and the automatic monitoring terminal are connected through a time request protocol; and the time control data and the automatic monitoring terminal are synchronous. The hot backup automatic switching time control system has the advantages that the control right can be switched without disconnecting the lighting operating circuit, the faults of the automatic monitoring terminal can be detected in time effectively, and the economic loss caused by wrong report or missing report of the faults is avoided.

Description

technical field [0001] The invention relates to an automatic switching system, in particular to a system for city lighting that can automatically switch time control terminals in a hot backup state. Background technique [0002] Urban lighting mainly refers to urban road lighting, building exterior lighting, landmark building lighting and so on. Among them, urban road lighting has a very important impact on the lives of citizens. No matter in the main traffic road or in the remote road, the lighting is closely related to personal safety and traffic conditions. If the lighting fixtures are not activated within the set time, it will directly lead to the chaos of the urban order, especially in the first-tier megacities. The incidence of traffic accidents on roads without lighting is much higher than that under normal lighting conditions, and small roads without lighting are also places where crimes frequently occur. Therefore, it is extremely important to start the city ligh...

Problems solved by technology

[0004] However, the response speed of this switching method is very slow, and it must be switched manually, and there is a blank period of lighting from the personnel response to the beginning of emergency rescue.

Sometimes the automatic monitoring terminal only has a small program problem, and then after it automatically returns to normal, it cannot automatically switch back to the automatic monitoring terminal control state, and it must be switched manually, wasting human resources
