Electric automatic door control system of railway vehicle

Abstract

The invention discloses an electric automatic door control system of a railway vehicle. The electric automatic door control system is mainly and technically characterized by comprising an external control signal device, a digital signal controller, an engine assembly, a pulse modulation wave, an alarming device, an automatic door clamping-extruding-resisting circuit, a rotation speed and position detection circuit and an automatic door; the external control signal comprises a microwave sensor and a smoke sensor and is connected with the digital signal controller, the digital signal controller is connected with the engine assembly through the pulse modulation wave, the engine assembly is connected with the rotation speed and position detection circuit, the rotation speed and position detection circuit is connected with the digital signal controller, the alarming device is connected with the digital signal controller, the automatic door clamping-extruding-resisting circuit is connected with the digital signal controller, and the engine assembly is connected with the automatic door. The electric automatic door control system of the railway vehicle, which is disclosed by the invention, is reasonable in design, has a clamping-extruding-resisting function and a smoke alarming function, and is low in cost, high in security and high in response speed.

Description

technical field [0001] The invention belongs to the technical field of electric automatic doors, in particular to a rail vehicle electric automatic door control system. Background technique [0002] The automatic door system is an important part of rail transit vehicles, which is directly related to the safety of passengers. At present, most domestic EMUs use single-wing sliding doors, and subways use double-wing sliding doors. In terms of driving mode, automatic doors can be divided into pneumatic doors (air operated doors) and electric doors. In terms of door movement methods, automatic doors mainly include single-wing sliding doors, double-wing built-in side-by-side doors and double-wing sliding doors. side-by-side doors etc. The automatic doors commonly used in China are mainly pneumatic doors, such as single-wing pneumatic sliding doors and double-wing pneumatic built-in side-by-side doors, but electric doors, as a new type of automatic door system, are gradually bein...

Problems solved by technology

The infrared pyroelectric sensor is controlled by detecting the 8-13μm infrared rays emitted by the human body. It is emitted by a microwave device, reflected by the human body, detected and amplified by the device, and then controls the subsequent circuit. Its characteristic is that it does not care about personnel. Whether it is moving or not, as long as it is within the scanning range of the sensor, it will respond and cannot close the door. This is not good for ensuring small changes in the environment in the car compartment, so it is not suitable for the inner end door connected by rail vehicles
