Embodiment Construction

[0027] 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.

[0028] The purpose of this embodiment is in order to provide a kind of interval detecting device of subway train, 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;

[0029] 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 colli...

Abstract

The invention discloses a spacing detecting device of a subway train. The spacing detecting device comprises a controller arranged on the subway train, a radar detection system, a travelling state system, a display, an alarming system, a power supply system and a signal receiving-transmitting device, wherein the radar detection system, the travelling state system, the display, an alarming system, the power supply system and the signal receiving-transmitting device are connected with the controller. The signal receiving-transmitting device is connected with the controller and used for transferring information with a signal receiving-transmitting device on an adjacent subway train. The radar detection system comprises a radar detector. The travelling state system comprises one or more train speed sensors. The display is a touch display screen. The alarming system comprises two voice alerters, 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-mounted power supply connected with the control switch. The controller is further connected with a speed reducing system and a brake system of the subway train. According to the system, the situation that in the prior art, the subway train spacing cannot be effectively detected, and consequently traffic accidents such as rear-end collision occurs is avoided.

Description

technical field [0001] The invention relates to an interval detection device for 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 important...
