4G RTU integrates traditional industrial RTU and full Netcom/4G/3G/5G data transmission functions into one, realizing comprehensive functions such as collection, counting, control, storage, alarm and transmission. It is also compatible with the data transmission function of the full Netcom/4G/3G/5G IP MODEM.

Classification of industrial routers(1) From the perspective of architecture, routers can be divided into the first-generation single-bus single-CPU structure industrial router, the second-generation single-bus master-slave CPU structure industrial-grade router, and the third-generation single-bus symmetric multi-CPU structure industrial-grade router , The fourth-generation multi-bus multi-CPU str···

Industrial 4G routers have two typical functions, namely data channel function and control function. Data channel functions include forwarding decision, backplane forwarding and output link scheduling, etc., which are generally completed by specific hardware; control functions are generally implemented by software, including information exchange, system configuration, and system configuration with···

In the architecture of the Internet of Things, an intermediate device is needed between two different networks at the perception layer and the network layer, that is, the "Internet of Things Gateway". The IoT gateway can be used for both wide area network interconnection and local area network interconnection. In addition, the IoT gateway also needs to have device management functions. Operators c···

After GPRS DTU is powered on, first read the working parameters stored in the internal FLASH (including GPRS dialing parameters, serial port baud rate, data center IP address, etc., which have been configured in advance).

DTU is the full name of GPRS data transmission unit. At present, in China, there is actually a clearer agreement on GPRS DTU: GPRS DTU is a GPRS wireless device specially used to transmit serial data through the GPRS network. The following introduces the common problems of DTU application and the working engineering of GPRS DTU.

Managed switch or unmanaged switch: If the network structure is simple, you can choose a plug-and-play unmanaged switch; and if you take into account the convenience of subsequent maintenance and other factors, the managed switch is a better choice, because Only managed switches can achieve redundancy.

The industrial Ethernet switch adopts the storage conversion and exchange method, and at the same time improves the Ethernet communication speed, and the built-in intelligent alarm design monitors the network operation status, so that the reliable and stable operation of the Ethernet can be ensured in the harsh and dangerous industrial environment.

DTU is an abbreviation for Data Terminal Unit. Broadly speaking, when communicating, the module units responsible for sending data information at both ends of the data transmission link are called DTUs. Under its action, format conversion and data collation and verification are performed on the transmitted information.In a narrow sense, DTU generally refers to the lower GPRS/CDMA transmitting term···

When customers want to buy 4G industrial routers, they don't know which brand is good, which brand is reliable, and which brand is trustworthy.So the question is, how to choose a 4G industrial router?What is the basis for selection? What 4G industrial router should I choose? The overall process can be divided into 5 steps:
