Embodiment Construction

[0024] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0025]When the train is running on the open ground, the air in front of the front of the train is squeezed out to both sides and the upper part of the train without hindrance, forming a subsonic flow movement, and the fluctuation of the pressure field formed in front of the train and around the train is relatively small. However, when the high-speed train breaks into the tunnel, due to the limitation of the g...

Abstract

The invention discloses a device for monitoring opening and closing state of a tunnel protection door. The device comprises a door state detector, an identity collector, an environment collector and adoor end controller, wherein the door state detector is arranged at the edge of a door frame of the protection door and used for collecting a door opening signal representing the current opening andclosing state of the protection door; the identity collector is used for collecting identity information of a master controller for controlling the current opening state; the environment collector isused for collecting current environment information under the control of a recorded door opening environment instruction; the door end controller is used for receiving and detecting the door opening signal, receiving and detecting the identity information when the protection door is opened, judging whether the situation of illegal cabin invasion occurs currently according to a detection result, generating the recorded door opening environment instruction and generating a door opening record containing illegal / legal door opening marks, the identity information and the environment information after the environment information is received. The working efficiency of detection personnel is improved, the applicability of the device is improved, and safety management of the protection door of a whole-line railway network is facilitated.

Description

technical field [0001] The invention relates to the field of railway rail transit, in particular to a device and system for monitoring the switch state of a tunnel protective door. Background technique [0002] With the rapid development of my country's railway network, the number of tunnels is increasing day by day. The status and safety of the ancillary facilities in the tunnel have an increasing impact on the normal operation of the railway. At present, railway tunnel protection doors have been widely used in developed countries such as Switzerland, Germany, the United States, Japan, etc. Insufficient, and then the lack of a unified supporting technology for the design and construction of railway tunnel protective doors, general technical conditions and quality inspection standards, resulting in various problems in the practical application of railway tunnel protective doors. These problems include: ①The door leaf is mostly made of reinforced concrete or steel plate san...
