Description

Technical Field

[0001] The present application relates to the field of railway transportation technology, and in particular to a railway integrated video outdoor control box. Background Art

[0002] The railway integrated video outdoor control box is a standardized front-end integrated equipment of the railway integrated video surveillance system. It is generally installed on a communication tower or trackside, so that the front-end equipment (for example, video cameras) can be installed and constructed outdoors more standardized and faster, reducing the maintenance workload of the front-end equipment in the later stage.

[0003] The railway integrated video outdoor control box is usually composed of a mechanical frame structure and electrical appliances arranged in the box. However, the railway integrated video outdoor control box in the prior art still has the following problems in actual use:

[0004] (1) There is no physical separation between the power distribution equipment in the control box and other equipment. There is no obvious division of the electrical appliances in the box. The AC input power distribution unit, which is mainly composed of circuit breakers, is in the same closed environment as other electrical appliances. Under special circumstances (such as thunderstorms or abnormalities caused by aging equipment), once the power distribution unit is ignited, it will be impossible to isolate the impact on other electrical equipment or network equipment;

[0005] (2) The control box does not have an automatic or remote closing function. When the main power circuit breaker 4022 in the control box is undervoltage, in a high temperature or high humidity environment for a long time, or the connection is unreliable, an abnormal tripping phenomenon will occur. At this time, the operator needs to go to the site to close the circuit. For video control boxes in mountainous areas, bridges or tunnels, it is quite inconvenient to handle.

[0006] (3) The control box does not have the function of monitoring and alarming the door opening and closing status. The existing railway integrated video outdoor video box generally uses a lock to fasten the box door. When the lock is not tight or the maintenance personnel forget to lock it, the box door can easily be blown open by strong winds. If it is not discovered in time, it will affect the overall service life. Utility Model Content
