In recent years, safety accidents have occurred frequently in the field of railway construction, warning us that we must use more scientific technological means to safeguard the safety of construction personnel. On June 4, 2024, the 42109 freight train on the Suijia Line collided with operators near Tangyuan Station, resulting in 6 deaths. The accident investigation showed that the operation team mistakenly identified the construction line category and carried out illegal operations on the down line, ultimately resulting in the tragedy of the train failing to brake urgently.

There are three major problems with traditional protection systems: firstly, manual protection is easily affected by factors such as fatigue, visual obstruction, and misjudgment of line types; Secondly, the visibility of physical warning devices drops sharply in harsh weather conditions such as strong light, rain, and fog; Thirdly, there is a risk of delay or omission in the transmission of sound and light signals when multiple job types collaborate. Especially in double line parallel sections, problems such as operators accidentally entering adjacent lines and insufficient braking distance of trains occur frequently, and there is an urgent need for technological means to reconstruct safety barriers.

Faced with this painPoint, Feitian Optoelectronics has launched a new generation of intelligent construction site railway train approach pre warning system, which uses high-precision laser radar sensing technology as the core to build a full chain safety barrier of "monitoring warning evacuation". The system scans the train's running trajectory in real time through a laser radar. When the train enters the preset monitoring area, it immediately triggers the sound and light alarm device - the high decibel alarm sound and the high brightness strobe light are synchronized to start, reserving sufficient evacuation time for construction personnel. Compared to traditional manual protection, this system has increased response speed by over 90%, eliminating security vulnerabilities caused by human misjudgment and communication delays.

The system adopts a solar powered architecture, equipped with new materials of photovoltaic panels and intelligent charging controllers, and built-in overcharge protection modules to ensure outdoor safetyLong term stable power supply in the environment. The system design implements the concept of "no wiring, high reliability": the front-end and back-end devices adopt 4G wireless transmission, support encrypted transmission and anti-interference algorithms, and ensure zero false alarms of the signal; Industrial grade protection design enables the equipment to operate stably for 7 × 24 hours in an environment ranging from -40 ℃ to 70 ℃, and key components meet protection standards. In addition, the system supports functions such as red light indication and automatic alarm suppression, adapting to the dynamic requirements of construction scenes.

Compared to traditional solutions, this system achieves three major leaps forward: safety protection shifts from "passive response" to "active warning", by detecting train approaches in advance and reserving sufficient avoidance time for operators; The construction efficiency has been upgraded from "manual monitoring" to "intelligent control", eliminating the hassle of complicated wiring and adapting to various terrains; The safety and reliability have shifted from "experience dependence" to "data-driven", achieving zero false alarms through radar review and logical algorithms.

Safety is no small matter, technology shows responsibility. The Feitian photoelectric train approach alarm system replaces empirical judgment with precise monitoring and passive protection with intelligent warning. It is not only a set of equipment, but also the "second line of insurance" for construction safety, providing peace of mind for every construction and reducing worries for every family. Choosing technological security is choosing a solemn commitment to life - this is the "safety code" for railway construction in the new era.
