In the busy rail transportation network, every temporary on-the-road work by rail workers is accompanied by potential hazards. Not only do they have to deal with a complex and ever-changing construction environment, but they also have to be constantly vigilant about speeding trains. In recent years, train collision accidents caused by various reasons have occurred from time to time, which has brought great threats to the life safety of railway workers.
Hazard analysis
In the railway industry, workers are often exposed to the following hazards:
(1) The impact force caused by the high-speed operation of the train and the injury caused by the impact force;
(2) It is difficult to control the safety distance between the construction area and the train operation area;
(3) The construction site is noisy and the line of sight is obstructed, and it is difficult to detect the approach of the train in time;
(4) Weak safety awareness of construction personnel, illegal operation, etc.
Accident cases
In a railway maintenance operation, for example, a group of workers went to work on the road without receiving a dispatch order. Due to the loud noise and obstructed view of the scene, they were unable to spot a high-speed train in time. Eventually, the train collided with the construction team, causing serious casualties and property damage.
Application of Feitian photoelectric train proximity warning system
In order to reduce the danger of railway workers temporarily on the road construction, Feitian Optoelectronics has launched a train proximity warning system. Through advanced radar detection technology and solar-powered modules, the system is able to monitor the running status of the train in real time and send an alarm signal when the train approaches the construction area.
The Feitian Optoelectronic Train Proximity Warning System is mainly composed of the following parts:
(1) Radar detection module: responsible for detecting the running status of the train;
(2) Solar power supply module: provide stable power support for the system;
(3) Alarm host control module: receive the signal of the radar detection module, and control the output of the alarm signal;
(4) 4G transmission module: transmit the alarm signal to the staff on the construction site in real time.
When the train enters the detection range of the radar detection module, the lidar will monitor the train status in real time. By processing these signals, the system can accurately determine the operating status and distance of the train. Once the train approaches the construction area, the alarm host control module will immediately send out an alarm signal and transmit the signal to the staff on the construction site through the 4G transmission module.
Compared with the traditional crossing alarm method, the Feitian photoelectric train proximity alarm system has the following advantages:
(1) There is no need to lay overly complicated cables, and the equipment is simple and easy to move;
(2) Accurate ranging, avoiding maintenance accidents caused by inaccurate ranging;
(3) Easy installation, reducing the workload and labor intensity of the staff;
(4) Real-time alarm, which can detect the approach of the train in time and remind the construction personnel to evacuate.
Rail workers face many dangers when they are temporarily on the road, and train collisions are one of the most serious threats. By introducing the Feitian Photovoltaic Train Proximity Warning System, we can provide timely safety and security for railway workers. The system not only has the functions of accurate distance measurement and real-time alarm, but also has the advantages of simple equipment layout. It is believed that in the near future, the Feitian photoelectric train proximity alarm system will become one of the important tools in the railway industry to ensure the safety of workers.
