Embodiment 1

[0048] see figure 1 , figure 1 It is an implementation flowchart of the train pressure wave protection control method in the embodiment of the present invention, and the method may include the following steps;

[0049] S101: Receive the flicker frequency of the sensing signal sent by the signal identification device.

[0050] Wherein, the flickering frequency of the sensing signal is obtained by the signal identification device identifying the signal sent by the signal generating device installed at the exit or entrance of the tunnel.

[0051] The pressure wave protection controller can be installed in the train in advance, and the signal generating device is installed at the exit and entrance of the tunnel, and the signal flashing frequency of the signal generating device installed at the tunnel exit and entrance is different, such as the signal flashing frequency of the tunnel entrance A, the flashing frequency of the signal at the tunnel exit is B, and a signal recognitio...

Embodiment 2

[0064] see figure 2 , figure 2 It is another implementation flowchart of the train pressure wave protection control method in the embodiment of the present invention, the method may include the following steps:

[0065] S201: When the train successively passes through a tunnel group whose distance between a preset number of tunnels is less than a preset length, the sensing signal of the tunnel group head tunnel entrance or the tunnel group tail end tunnel exit sent by the signal identification device flickers at a flickering frequency.

[0066] Wherein, the flickering frequency of the sensed signal is obtained by the signal recognition device identifying the signal sent by the signal generating device installed at the tunnel entrance at the head end of the tunnel group or at the tunnel exit at the tail end of the tunnel group.

[0067] For scenarios where the distance between adjacent tunnels is relatively short, a length value can be preset. If the distance between every t...

Abstract

The invention discloses a train pressure wave protection control method. The method comprises the following steps that a sensing signal flicker frequency sent by a signal identification device is received; the current train entering and exiting tunnel state corresponding to the sensing signal flicker frequency is looked up from a train entering and exiting tunnel state table; when it is determinedthat the current train entering and exiting tunnel state is in the entering tunnel state, a pressure wave protection opening instruction is sent to a pressure wave protection actuator, so that the pressure wave protection actuator closes a valve to isolate a ventilation opening between the interior and the exterior of a vehicle; and when it is determined that the current train entering and exiting tunnel state is in the exiting tunnel state, after the first preset time delays, a pressure wave protection ending command is sent to the pressure wave protection actuator to enable the pressure wave protection actuator to open the valve to open the ventilation opening between the interior and the exterior of the vehicle. According to the method, the pressure wave is prevented from being transmitted into the vehicle, adverse effects on passengers are prevented, and the passenger experience is improved. The invention further discloses a train pressure wave protection control device and equipment as well as a storage medium, which have corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train pressure wave protection control method, device, equipment and computer-readable storage medium. Background technique [0002] When the train is running in the tunnel, the surrounding air pressure will change drastically, forming a pressure wave, which will cause tinnitus and dizziness to the passengers. The pressure wave protection device is to prevent the pressure wave from entering the train. [0003] The existing pressure wave protection control method is to identify whether the train passes through the tunnel by monitoring the pressure difference between the inside and outside of the car through a pressure wave sensor installed on the front of the car. When the unique pressure difference characteristic is recognized when entering the tunnel, the inside of the car is isolated from the outside of the car by closing the air inlet and outlet to prevent pressure wave...
