Problems solved by technology

However, if the train driver finds that there is an obstacle on the track in front of the train or that the track has an accident and needs to brake urgently, due to the lack of braking distance, accidents generally cannot be avoided, which is a problem that needs to be solved.

Embodiment Construction

[0021] The railway signaling system of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] refer to figure 1 , figure 1 It is a schematic diagram illustrating the structure of the railway signal system of the present invention, the system shown in the figure includes a signal processing device (1), an identification mark (2), and a control center (3), wherein the signal processing device (1 ) is installed on the train, and is mainly used to send information such as the position and speed of the train on the track to the outside, receive information such as position and speed sent by the signal processing device (1) of other trains, and receive information such as the position and speed of the train from the control center (3) Send the operation instructions to the train, and according to the received information and instructions, perform collision simulation on all the trains on the track area where the train...

Abstract

The invention relates to a railway signal system adopting a centerless communication mode, which comprises a signal processing device (1), an identification mark (2) and a control center (3), wherein the signal processing device (1) is arranged on a train, and the identification mark (2) is arranged on a rail along the railway line. The signal processing device (1) finds out the current position of the train by reading the identification mark (2) and sends out running information, such as the current position, the speed and the like of the train on the rail; and the signal processing device (1) receives the running information sent from other trains, receives the running instruction sent from the control center (3) and simulates collision of all trains on the current position according to the received running information and the received running instruction. When the probability of occurrence of a collision accident is detected, warning information is sent to a train driver and other adjacent trains to enable the driver of each train to pay attention to the condition and adopt proper action to avoid the collision accident.

Description

【Technical field】 [0001] The invention relates to railway signal technology, in particular to a railway signal system adopting a centerless communication mode. 【Background technique】 [0002] At present, the general railway signal system usually monitors the movement of trains on the railway by the control center. The train can only run according to the command after receiving the command from the control center. However, due to the high speed of the train and the long parking distance, if any error occurs, It cannot immediately stop the train within a short distance like a car. Usually, the stopping distance needs to be hundreds of meters to several kilometers. When an emergency stop is found, it usually takes tens of seconds to stop the train. Because only the control center knows the running status of each train on the entire track, the control center will order the train to brake urgently before the accident may occur tens of seconds, so as to avoid the accident. Howeve...
