Embodiment Construction

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0026] The purpose of this embodiment is to provide a subway train spacing detection system, such as figure 1 As shown, the subway train spacing includes a PLC controller arranged on the subway train, and a radar detection system connected to the PLC controller, a driving status system, a display, an alarm system, a power supply system and a signal transceiver;

[0027] The PLC controller is also connected with the deceleration system and braking system of the subway train. It is to automatically control the subway train to accelerate, decelerate, stop and other operations when the detected subway train distance is less than the safe distance, but the subway train driver fails to deal with it in time, so as to avoid the occurrence of rear-end collision accidents. ...

Abstract

The invention discloses a subway train distance detection system. The system comprises a controller arranged on a subway train, a radar detection system, a driving state system, a displayer, an alarm system, a power supply system and a signal transceiving device, wherein the radar detection system, the driving state system, the displayer, the alarm system, the power supply system and the signal transceiving device are connected with the controller; the signal transceiving device is connected with the controller and used for carrying out information transmission with a signal transceiving device on an adjacent subway train; the radar detection system comprises a radar detector; the driving state system comprises one or more train speed sensors; the displayer is a touch display screen; the alarm system comprises two voice alarms, two buzzers and a subway train outline marker lamp; the power supply system comprises a control switch connected with the controller, and a subway train vehicle-mounted power supply connected with the control switch; the controller is further connected with a speed reducing system of the subway train and a brake system. According to the subway train distance detection system, the problem that the subway train distance cannot be effectively detected in the prior art is solved, so that the situation of traffic accidents such as rear-end collision occur is avoided.

Description

technical field [0001] The invention relates to a detection system for distance between subway trains. Background technique [0002] With the acceleration of China's urbanization process, the pressure brought by the increase of urban population to urban traffic is becoming more and more obvious. However, the development of urbanization must not be constrained by traffic pressure. Therefore, the underground transportation corresponding to our traditional ground transportation has become a new channel to relieve the pressure of urban traffic. Here it is the subway traffic that current large and medium-sized cities are doing their utmost to develop. At present, China's Beijing, Tianjin, Hong Kong, Shanghai, Guangzhou, Shenzhen and other cities have subways, and subways in many cities are also under construction. Because of the comfort, speed and convenience of the subway, it has become an important means of transportation for people to travel, and the subway has become an im...
