how to remotely control the industrial 4G router through public network IP?

Industrial 4G router can support remote control and provide flow monitoring and alarm mechanism, which facilitates the unified management of technicians, reduces network failures, and facilitates the later maintenance of equipment.

Analysis of the Function of Serial Device Server

Analysis of the Function of Serial Device Server

In short, serial device server is a kind of network communication interface conversion equipment, which can convert common RS-232, RS-485, RS-422 serial ports into TCP/IP network interface, and realize both way transparent data transmission between RS-232, RS-485, RS-422 serial ports and TCP/IP network interface. This paper introduces the relevant functions of serial device server.

What is the working principle of industrial 4G router?

What is the working principle of industrial 4G router?

The industrial 4G router works in the third layer (network layer) of the seven-layer network protocol. The industrial router receives a network packet at the network layer and forwards it to the destination address contained in the packet. Therefore, when industrial routers transmit data, they first need to find the target address from the data packet, add the next MAC address before the frame lattice, and at the same time, the TTL domain value of IP data header begins to decrease, and recalculate the checksum. The working principle of industrial router is the same as that of router, which can find the routing table in the device according to some routing communication protocol.

How to build LoRa-based IOT?

How to build LoRa-based IOT?

The LoRaWAN network architecture is deployed in a star topology (same as the Zibgee), and each point acts like a paratrooper, communicating with each other when they are connected. Base stations transmit data between sensor nodes and network servers. The communication between sensor nodes and base stations is executed through wireless channels by using LoRa physical layer, while the connection between gateway and central server is processed through IP-based backbone network.

How to choose the wireless module in the industrial IOT?

How to choose the wireless module in the industrial IOT?

Key issues in choosing IOT transmission: 1. How to deal with customers and configuration? 2. How to ensure transmission security? 3. What are the pain points related to access point technology?

LoRa proposes a new geolocation solution at a very low price

LoRa proposes a new geolocation solution at a very low price

LoRaWAN is a new global standard for low power consumption, wide area network (LPWAN) communications developed by LoRa Alliance. LPWAN allows batteries used more than 10 years. In many areas where is strictly cost control, such as agriculture, smart cities, meter reading, etc., low power consumption makes large-scale deployment of the Internet of Things possible. LoRa modules price about 20 yuan and cost nothing. LoRaWAN is supported by major network operators worldwide.

Differences between Low Power Bluetooth (BLE) and ZigBee in Internet of Things Applications

Differences between Low Power Bluetooth (BLE) and ZigBee in Internet of Things Applications

With the expansion of low power consumption and wide area network (LPWAN) market, the low power consumption protocols for Internet of Things (IoT) applications have more choices. B compares Bluetooth and Bluetooth low energy consumption (BLE) with ZigBee so that you can better understand which wireless protocol to use on connected devices. In simple terms, Bluetooth is near field communication and ZigBee is local area network.

How to Guarantee the Stability of Industrial 4G Router?

How to Guarantee the Stability of Industrial 4G Router?

What factors can guarantee the stability of industrial 4G routers in the transmission process? 1. Chip scheme 2. Hardware Circuit Protection 3. Watchdog protection 4. Timing Restart 5. Antenna signal The core of the industrial 4G router is the chip fixed on the circuit board, like the CPU in the computer, which grasps the core data of the equipment work Industrial 4G routers are often used in harsh industrial scenarios. They are different from home routers that work in greenhouses for a long time.
