Description

Pressure wave regulating and controlling equipment for high-speed railway vehicle Technical Field The application relates to the technical field of rail vehicles, in particular to pressure wave regulating equipment for a high-speed railway vehicle. Background In the prior art, pressure wave controllers applied to high-speed railway vehicles are based on sensing and regulating pressure. The pressure change in the system is monitored in real time by a built-in pressure sensor and compared with a set value. When the actual pressure reaches or exceeds the set value, the controller triggers corresponding control actions, such as opening or closing a valve, so as to maintain the stability of the system pressure. The method has the core aims to ensure the normal operation of the system in a set pressure range and avoid equipment damage or operation faults possibly caused by overhigh or overlow pressure, and specifically comprises two parts: The first part, pressure detection and execution, namely the pressure wave controller senses pressure change through the pressure detection mechanism, when the corrugated pipe is subjected to pressure, the corrugated pipe can generate expansion deformation, and the deformation further drives the swing rod to act. The swing rod controls on-off by poking the contact, so that accurate control of system pressure is realized; And the second part is used for signal processing and control, wherein a pressure sensor arranged in the controller monitors the pressure change in the system in real time and compares the pressure change with a set value. When the actual pressure reaches or exceeds the set point, the controller triggers a corresponding control action, such as shutting down the circuit or activating a protection mechanism, to maintain the system pressure within a safe range. However, the pressure wave controller in the prior art is mainly passive for pressure wave regulation, and mainly depends on the airtight design of a train and a simple pressure release device. For example, by providing a pressure release valve in the train body, when the pressure in the cabin exceeds a certain threshold value, the release of the excessive pressure is automatically opened. This passive adjustment has the following disadvantages: Firstly, the regulation is not timely, namely the response speed of the pressure release valve is limited, and the pressure release valve cannot be timely regulated when the pressure wave is rapidly changed, so that the pressure fluctuation in the carriage is large, and the comfort of passengers is influenced; secondly, the regulation precision is low, the passive regulation cannot be accurately controlled according to the real-time pressure change, and the simple release or closing operation can only be carried out when the pressure exceeds a preset value, so that the fine pressure regulation cannot be realized; And thirdly, the pressure cannot be actively adjusted according to the running state (such as entering, crossing, exiting and running in a tunnel) of the train by passive adjustment, so that the adaptability is poor. Fourth, the pressure inside and outside the train cannot be regulated simultaneously, namely, the pressure change inside and outside the train is asynchronous, so that the pressure difference inside and outside the carriage is overlarge, and the comfort of passengers and the safety of the vehicle structure are affected. Disclosure of Invention The embodiment of the application provides pressure wave regulating equipment for a high-speed railway vehicle, which aims to solve the problems that the existing pressure wave regulating device cannot actively interfere, regulate the pressure inside and outside a train, has poor adaptability and affects the comfort of passengers. In order to achieve the above purpose, the present application provides the following technical solutions: a pressure wave regulating apparatus for a high speed railway vehicle, comprising: The air inlet assembly is positioned on the head car and comprises an air inlet pipeline, a driving device and an air outlet pipeline, the air inlet pipeline can be communicated with the outside of the train, two ends of the driving device are respectively connected with the air inlet pipeline and the air outlet pipeline, and the driving device is used for sucking air flow outside the head car of the train; The air pipe assembly is positioned in a carriage of the head car and/or the middle car and comprises a conveying air channel, one end of the conveying air channel is connected with the air outlet pipeline, and the other end of the conveying air channel is communicated with the carriage and/or the outside of the car and used for conveying air into the carriage and/or discharging the air out of the car. Optionally, the conveying air duct includes: The first air pipe is communicated with the conveying air duct; The first auxiliary air pipe is communicated with the outside of the train, and t
