Embodiment 1

[0041] Embodiment 1. A detection device is installed on the train. During the operation of the train, the detection device periodically sends out electromagnetic wave detection signals of specific intensity and frequency;

[0042] A target device and an alarm device are set at the railway operation site, and the target device returns a feedback signal to the train after receiving the detection signal sent by the train;

[0043] The detection device on the train calculates the distance between the railway operation site and the train by analyzing the phase relationship or time difference between the detection signal and the feedback signal according to the received feedback signal, and calculates the time required for the train to arrive according to the real-time speed of the train;

[0044] The detection device of the train sends information such as distance and train speed, or calculates the time required for the arrival of the train, to the railway operation site through a w...

Embodiment 2

[0046] Embodiment 2. A detection device and an alarm device are set at the railway operation site. During the operation, the detection device periodically sends out electromagnetic wave detection signals of specific intensity and frequency;

[0047] A target device is set on the train, and the target device returns a feedback signal to the job site and provides vehicle speed information after receiving the detection signal sent by the job site;

[0048] The detection device at the work site calculates the distance between the railway train and the work site according to the feedback signal, or further calculates the time required for the train to arrive based on the speed information;

[0049] The alarm device sends out a corresponding warning signal according to the distance or time determined by the detection device. The closer the distance and the shorter the time, the higher the alarm level. The alarm mode is the same as that in Embodiment 1.

Embodiment 3

[0050] Embodiment 3. A target device is set on the train. During the operation of the train, the target device obtains its own position information at any time according to the GPS system or the railway communication system, and periodically sends out information including the real-time position and speed of the train;

[0051] A detection device and an alarm device are set at the railway operation site, and the detection device obtains its own position information at any time according to the GPS system or the railway communication system, and receives the position and speed information sent by the train, and determines the distance of the train by comparing the positions of the two, and Calculate the time required for the arrival of the train according to the speed of the train;

[0052] The alarm device at the job site sends out corresponding warning signals according to the distance or time determined by the detection device. The closer the distance and the shorter the tim...

Abstract

The invention discloses a method and a system for the safety caution of railway operation, which is used for guaranteeing the safety of railway running. The method for the safety caution of the railway operation comprises the following steps of: measuring the distance between a train and an operational site periodically; and when the distance between the train and the operational site reaches a warning value or the time which is calculated according to the speed of the train and is required by reaching the operational site by the train reaches a warning value, sending a warning signal to the operational site. The safety caution system for realizing the method comprises a distance measurement system for measuring the distance between the train and the operational site and a warning device for sending the warning signal according to a measuring result of the distance measurement system. By utilizing the method and the system, staffs working on railways can get train approaching information in time to make corresponding preparations in time and leave railways.

Description

technical field [0001] The invention relates to a railway construction safety protection method and equipment, in particular to a railway operation safety warning method and a safety warning system for reminding railway field workers of train approaching information. Background technique [0002] Railway staff usually carry out operations such as inspection and maintenance of railways during the intervals of train operation. Therefore, it is a very important task to ensure the operation safety and train operation safety. With the continuous acceleration of trains and the continuous development of high-speed railways, the requirements for safety protection work are also getting higher and higher. [0003] The simpler method is to arrange special personnel for protection and monitoring, and notify the on-site operators in time when a train is found approaching. This will not only consume redundant manpower, but also pose a threat to the personal safety of relevant operators ...
