Problems solved by technology

[0008] The present invention solves the problem that the existing train on-board control equipment can only rely on the signals provided by ground facilities such as track circuits, ground transponders, trackside cables, ground wireless communication base stations, etc. to obtain the information of the current line, and cannot directly obtain the information of other nearby trains. Defects in information such as position and speed

Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] Such as figure 1 As shown, the subway auxiliary anti-collision system adopts the following technical scheme: the anti-collision system includes in-vehicle equipment and out-of-vehicle equipment; Auxiliary sensing module: the in-vehicle equipment is located inside the driver's cab, including the on-board host, the power supply circuit of the power box, the cab anti-collision warning terminal, self-test and fault diagnosis modules. The signal sending and receiving module is realized by the combination technology of sending and receiving. The technology of sending and receiving combined system adopts the technology that the signal transmitting device and the signal receiving device share the same sensor; the signal sending and receiving module is used to judge whether the collected data is for the vehicle If the signal sent is yes, the relative speed of the front a...

Abstract

The invention relates to a subway auxiliary collision avoidance system and a subway auxiliary collision avoidance method. The collision avoidance system mainly comprises a signal sending device, a signal receiving device, a vehicle interface module, an auxiliary sensing module, a vehicle-mounted host, a power source box power supply circuit, a driving cab collision avoidance warning terminal and a self-inspection and fault diagnosis module. The collision avoidance method includes synchronously performing signal sending and signal collecting, namely sending and collecting signals through receiving and sending combination; performing signal detection by a signal processing unit in real time for distance measuring; when reaching an alarming distance, performing audio alarming by using a buzzer through a prewarning display terminal. Receiving and sending combination technology refers to that the signal sending device and the signal receiving device share a sensor. Compared with the prior art, the subway auxiliary collision avoidance system and the subway auxiliary collision avoidance method have the advantages that bidirectional distance measuring can be realized, and distance measuring accuracy is high.

Description

technical field [0001] The invention relates to an urban rail transit signal system, in particular to a subway auxiliary collision avoidance system and an avoidance method. Background technique [0002] The urban rail transit signal system is the key system equipment to ensure the safety of train operation, realize the modernization of traffic command and train operation, and improve transportation efficiency. [0003] The urban rail transit signaling system usually consists of the Automatic Train Control (ATC) system. The ATC system includes three subsystems: the automatic train monitoring system (ATS for short), the automatic train protection subsystem (ATP for short), and the automatic train operation system. system (referred to as ATO). [0004] The three subsystems form a closed-loop system through an information exchange network, realizing the combination of ground control and on-board control, and on-site control and central control, forming a system based on safety ...
