Description
TECHNICAL FIELD
[0001] The utility model relates to train control system technical field especially is involved in a kind of train front nose cover upturning type opening and closing mechanism control system. BACKGROUND
[0002] With the trend of gradually increasing the appearance of train outside and the speed level of operating train, the driver's cabin front nose cover is usually used to wrap the coupler and anti-climber, and in order to meet the normal shunting or emergency rescue of the vehicle, an opening and closing mechanism is generally installed at the end of the vehicle to enable the front nose cover to be opened to expose the coupler. Currently, there are mainly two forms: 1. Half-opened inward opening form, like the front end opening and closing mechanism of high-speed rail motor train unit, which uses a travel switch to provide signal feedback function; 2. Mechanical upturning form, which also uses a travel switch to monitor the state. For example, the patent CN 220769158U discloses a kind of evacuation door redundancy lock and the patent CN 215042777U discloses a kind of train and coupler control interlock device, both of which use travel switches to monitor the state.
[0003] For the full-automatic driving system, the signal feedback by the travel switch is needed to determine the state of the train. However, the failure of the travel switch itself will affect the judgment of the real state of the train by the remote OCC control center, such as locking in place, fully opening, etc. In particular, after the mechanical upturning opening and closing mechanism is accidentally opened, the front nose cover will be lifted to the front lifting glass position, affecting the passenger's view; and in severe cases, it may cause train speed limit and passenger evacuation. INVENTION CONTENTS

[0021] The specific embodiments of the utility model are further explained in detail by comparing the drawings and describing the embodiments.
[0022] As shown in Figure 1 and Figure 2 The train front nose cover upturn type opening and closing mechanism control system, the two sides of the front nose cover are arranged in the front part of the train through a pair of locking mechanisms, and the coupler at the front end of the train is covered by the front nose cover; the locking mechanism 1 corresponding to each side of the front nose cover in the front part of the train is provided with a travel switch 2, and the two travel switches are connected with the controller of the train through the wire harness.
[0023] The rear part of the front nose cover is arranged on the train through a hinge, and the locking mechanism and the corresponding travel switch are arranged corresponding to the front part side of the front nose cover.
[0024] The locking mechanisms and the travel switches on the two sides of the front nose cover are symmetrically arranged. The two travel switches are connected through the parallel line 4. After the two travel switches are connected in parallel, the train false report guarantee condition can be greatly reduced, the authenticity of the train opening and closing mechanism state feedback is improved, and the operation failure index is reduced.
[0025] The controller is connected with the parallel line through the main wiring 3; further, the main wiring is arranged corresponding to the travel switch lead line on one side, which is beneficial to arrangement.
[0026] The front part of the train is provided with a driver's room, and the driver's room is provided with a display screen connected with the controller and capable of displaying the working state of the opening and closing mechanism, which is intuitive.
[0027] The working principle of the utility model is explained as follows:
[0028] When any one of the travel switches fails, the train will not report a signal of <opening and closing mechanism opening>, and at this time, the state on the display screen of the OCC remote control center is still normal, even if the unilateral opening situation really occurs in reality, the locking mechanism on the other side can also ensure that the front nose cover will not be lifted, which is the real state of the train, and does not affect the train operation.
[0029] When both of the travel switches fail, the state on the display screen of the driver's room is that the opening and closing mechanism is opened; by connecting the two travel switches in parallel, the false report guarantee situation of the train can be greatly reduced, the authenticity of the opening and closing mechanism state feedback of the train is improved, and the operation failure index is reduced.
[0030] The above is only the description of the preferred embodiment of the utility model, and the above technical features can be combined to form multiple embodiment schemes of the utility model.
[0031] The utility model has been described above in combination with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode, as long as various non-essential improvements are made by adopting the concept and technical scheme of the utility model, or the concept and technical scheme of the utility model is directly applied to other occasions without improvement, which is within the protection scope of the utility model.
