4G industrial-grade VPN routers provide wireless access networks for tunnel solutions

High-speed rail and highway tunnel monitoring

Because the tunnel can shorten the mileage, protect the environment, improve the alignment, and improve the road and rail traffic Therefore, most modern highways and railways use tunnel construction when they encounter complex terrain and geological conditions.

The tunnel is a concealed project underground. The underground geological conditions are complex, and there are many potential and unpredictable geological factors. A little carelessness will cause landslides, subsidence, mud and water inrush, deformation of supporting structures, injuries to personnel and equipment, etc. , Which seriously affects the safety of the tunnel.

In order to ensure the safety of the tunnel project and forecast the danger in time, it is very important to monitor and evaluate the safety and stability of the tunnel project. The main purpose is to understand the operation of the tunnel through monitoring methods. The established monitoring system is designed to monitor, evaluate and predict the tunnel project Advantages and avoidance of disadvantages have become an urgent need for the development of modern tunnel engineering.

The tunnel has a traffic control system, a lane indication system, a harmful gas monitoring system, and a lighting control system.

The tunnel monitoring system is generally connected to an IO module by a PLC, and collects data from various sensors and controls various devices through the IO module.

zoko-link launched a complete tunnel solution, including 4G industrial-grade VPN router to provide wireless access to the network, Ethernet IO module to collect sensor data and control DO output, RS485 can be used as a Modbus master station to communicate with various RS485 smart devices.

4G industrial-grade VPN routers provide wireless access networks for tunnel solutions：

Use the zoko-link 4G wireless industrial router to assist the staff in monitoring the gas (carbon monoxide, oxygen), water, temperature, humidity, and camera in the tunnel. Real-time monitoring of the running dynamics of high-speed rail and vehicles in the tunnel, as well as the concentration of carbon monoxide and carbon dioxide in the tunnel.
