Application of 5G Router with sim card slot in Tunnel Monitoring

With the development of traffic engineering construction and the cause of the traffic, increasing traffic flow, slightly condition improvement and the complexity of the transport of goods, increased traffic tunnel and tunnel fire sources such as risk, caused many serious catastrophic accident, especially the fire accident, it is not only a serious threat to human life and property safety, And to the traffic facilities, human production activities caused huge damage. Intelligent monitoring of tunnel becomes more and more important.

The monitoring system is mainly to collect the video information in the tunnel (road vehicle situation and illegal behavior situation), environment-related indicators (such as air quality), vehicle flow information (such as the number of vehicles passing by during a period of time), and send the data to the monitoring center through the 3G/4G/5G network.

The tunnel monitoring system is mainly composed of three subsystems, namely, acquisition equipment, transmission equipment and upper computer management platform (data center) in the front section.

Among them, the requirements for transmission equipment are relatively high. After all, the environment inside the tunnel is relatively harsh, mainly reflected in temperature, humidity, signal stability, etc., so the E-Lins H900f industrial 5g router with sim card slot is adopted in this system. As a transmission terminal for tunnel monitoring, H900f has the following characteristics:

1. Adopts high-performance industrial-grade wireless module, and uses high-performance industrial-grade 32-bit communication processor;

2, WDT watchdog design, to ensure the stability of the system, using a complete anti-drop mechanism, to ensure that the data terminal is always on line;

3, Provide RS232 (or RS485) serial port, Ethernet port, DIO and WIFI interface, can be directly connected to serial port devices, Ethernet devices and WIFI devices;

4, Ethernet interface built-in 1.5KV electromagnetic isolation protection, SIM/UIM card interface built-in 15KV ESD protection;

5, Support various VPN, such as IPSec, PPTP, L2TP, etc.;

6, can support 5-40V voltage by default

The use of operator network transmission related equipment, save more wiring costs, easy to operate; It solves the 3G/4G/5G signal coverage problem through the operator to do a good job of indoor coverage, and can also increase the cost of on-site maintenance personnel to achieve real-time remote monitoring.
