With the rapid development of railway construction, the safety of railway construction sites has become increasingly prominent. Especially in areas where railways are close to business lines, the operation of large machinery often coexists with the operation of trains, which poses a very high safety risk. Once a large machinery invades the railway limit, it may not only cause serious traffic accidents, resulting in casualties and property losses, but also may have a serious impact on the normal operation of the railway. Therefore, it is necessary to develop a system to monitor and warn the operating status of large machinery in real time to prevent it from invading the railway limit.
Secondly, the traditional railway construction safety management method often relies on manual inspection and on-site monitoring, which is not only inefficient, but also prone to negligence and misjudgment. The railway near the business line of large machinery anti-encroachment alarm system using advanced sensing technology and intelligent analysis algorithm, can real-time monitoring of the operation position and dynamics of large machinery, once the machinery into the business line of the limit, the system will immediately send an alarm, remind the operator to take timely countermeasures, to avoid safety accidents.
LiDAR is installed at both ends of the robotic arm, and ultra-wide-angle cameras are used above, integrating radar detection technology and intelligent analysis algorithms to monitor the machinery and equipment constructed along the railway in real time. As soon as an unusual intrusion or overrun is detected, this high-pitched horn will immediately sound an alarm, with enough decibels to be heard by the entire construction site, and the police lights above will flash to notify the staff to deal with it.
The system works very cleverly. It is installed in the construction along the railway, can realize the large mechanical intrusion alarm within 80 meters, the radar on both sides can form an invisible light curtain parallel to the track, divide the early warning area and the alarm area, when the large machine touches the safety line, the vehicle voice prompter will send out an alarm sound, and the on-site warning light will alarm to remind the illegal operation. This real-time and accurate working method can ensure the construction safety and stable operation of the railway to the greatest extent, and avoid major safety accidents.
Compared with conventional protection methods, the anti-encroachment alarm system of large machinery near the business line of the railway has the characteristics of high intelligence and automation, which can monitor the intrusion behavior of construction along the railway line in real time and accurately, and greatly reduce the workload and cost of manual monitoring. In addition, it adopts advanced radar detection technology and intelligent analysis algorithm, which can effectively identify and warn various potential safety hazards, reduce the false alarm rate, and improve the level and effect of construction safety protection along the railway. In addition, this system also has good scalability and flexibility, which can meet different usage scenarios, and has been successfully applied in Shanghai, Jiangsu and other places.
