The 4G cellular router is an industrial Internet of Things high-speed router that is fully compatible with 4G/3G/2G networks and uses public LTE networks to provide users with wireless remote data transmission.
Compared with home routers, 4G cellular routers are more secure and stable, and have a wider range of applications. In addition to the features of a home router, the stability, large bandwidth, and fast response of industrial server projects are facilitated.
4G cellular router has been used in industrial control, environmental monitoring, intelligent parking, transportation and other industries for many years.
Intelligent parking application
When the vehicle leaves, the terminal sensing device transmits the collected license plate number information to the control center through the 4G cellular router. The server calculates the parking time and payment amount, and transmits them to the scene. The driver can pay by scanning the code. Wireless network can be selected for obstacles, and WAN + 4G network can be selected indoors.The whole process network is fast, the remote management is convenient, the operation cost is optimized, the parking management is more intelligent, and the comfortable parking experience is created.
Solar Energy Monitoring Based on Internet of Things
Nowadays, solar energy has been widely used as a renewable and clean energy, and a large number of distributed solar power plants have been built and put into operation. It is essential for real-time monitoring, fault diagnosis, power prediction, monitoring and management of active/reactive power control systems, and routine maintenance such as component replacement or solar panel cleaning in power distribution systems.
Advantages and disadvantages of 4G cellular router.
Remote configuration of the device
Support remote control platform. Centrally monitor, configure, upgrade, diagnose, maintain and control a large number of equipment scattered in different regions. It greatly reduces the maintenance costs of operators, integrators, equipment suppliers and other parties, and improves the management efficiency.
Easy to deploy and implement
It is very convenient to realize the safe, stable and reliable networking of acquisition terminals in various places. Large networking scale, unlimited deployment distance, short construction period, less initial budget investment, providing technical support for data wireless communication transmission.
Industrial design
High and low temperature resistance, lightning protection, anti-static, high level IP30 protection, can work stably in all kinds of harsh natural climate.
Better stability
The 4G cellular router provides a highly flexible, secure and reliable solution for your industrial wireless network. Can connect 6V ~ 35V wide working voltage, -20 ℃ ~ 70 ℃ wide working temperature. It supports a variety of wireless configurations and applications. Customized control methods, powerful watchdog and disconnect and reconnect mechanisms greatly improve the reliability of the entire wireless network.
The following points should be noted when purchasing a 4G cellular router.
Workmanship and appearance
To a large extent, the appearance and process of the product can reflect the manufacturer's attitude towards the product, and the appearance of the product is also a reference standard. At present, most of the industrial wireless routers on the market are metal shell, preferably metal plate shell, and the protection level can reach IP30.
Agreement
When choosing a 4G cellular router, you must consider the open standard protocols supported by the 4G cellular router. Routers with open standard protocols mean good premises for the interconnection of devices, and supported protocols mean flexible and efficient designs.
High cost performance
Cost-effectiveness is a major factor in choosing a 4G cellular router. The performance is mainly based on its actual needs, such as working voltage, temperature, stability and coverage, and the specific engineering environment corresponds to the corresponding indicators.
Brand
The establishment of large brands in the industry often has profound historical accumulation and technological maturity, and product quality and after-sales service will be greatly guaranteed. Many small brands are full of "Shanzhai products".
The 4G cellular router is a Layer 3 device that uses IP address addressing to provide end-to-end services from a source IP to a destination IP address.The working principle is as follows: the router receives the data packet, extracts the target IP address and the subnet mask, and calculates the target network address; Arching the routing table according to the target network address, and if the target network address is found, sending to the next router according to a corresponding outlet; If not, check to see if a default route exists.If it exists, it is sent to the next router according to the exit of the default route; If not found, an error ICMP packet is sent to the source IP to indicate that the packet could not be delivered.
Industrial 4G routing is suitable for industrial applications, and the router network access mode is through the 4G mobile network. Internet is also very stable.
