PublishTime： 2023-10-11 Article Source：usr News

The working principle of a 4G LTE modem is mainly divided into the following three parts:

Data acquisition: the 4G LTE modem communicates with the device through the serial port or network interface to obtain the data to be transmitted.

Data processing: the 4G LTE modem processes the collected data, including format conversion, coding, compression, etc.

Data transmission: The processed data is transmitted to the upper computer or cloud platform through GPRS, CDMA, 3G, 4G, and other wireless communication technologies or wired communication technologies.

The advantage of a 4G LTE modem is that it can simplify the process of device acquisition, processing, and transmission, making it easy for users to monitor and manage devices remotely. In addition, the 4G LTE modem also has the advantages of high stability, strong security, and convenient use.

In the application scenario of distribution network automation, a 4G LTE modem is usually used together with PLC (programmable logic controller), RTU (remote communication terminal), field bus, and other devices to build a complete

Distribution automation system. In this system, the PLC is responsible for collecting field data, the RTU is responsible for simple data processing and storage, and the 4G LTE modem is responsible for transmitting the processed data to the host computer or cloud platform. This multi-level data processing method can make the system more stable and reliable.

In addition, the 4G LTE modem can also be used for remote control of devices. Users can remotely control the equipment through the host computer or cloud platform to realize the remote switching and parameter adjustment of the equipment. This remote control mode is not only convenient for users but also can improve the use efficiency of the equipment.

Generally speaking, a 4G LTE modem is an important terminal equipment in the field of distribution network automation and has important application value. With the continuous development of distribution automation technology, the function and performance of 4G LTE modems are also improving, and it is expected to become an important development trend in the field of distribution automation in the future.

The function of the 4G LTE modem distribution automation terminal

The 4G LTE modem distribution automation terminal is an important device in the distribution automation system, and its main functions are as follows:

Data collection: the 4G LTE modem can collect the relevant data of the distribution network site, including voltage, current, power, temperature, etc., to provide the basis for subsequent data processing.

Data processing: the 4G LTE modem simply processes the collected data and stores the processed data.

Data transmission: 4G LTE modem can transmit the processed data to the host computer or cloud platform so that users can remotely monitor and analyze the data through the host computer or cloud platform.

Remote control: 4G LTE modem can receive remote control commands sent by the user through the upper computer or cloud platform, and realize remote switching and parameter adjustment of the device.

Data storage: 4G LTE modem can store data locally to facilitate subsequent data query and analysis.

Generally speaking, the 4G LTE modem is an indispensable part of the distribution automation system, which provides important technical support for distribution automation.

Explanation of 4G LTE modem distribution automation terminal wiring

Wiring of a 4G LTE modem distribution automation terminal refers to the process of physically connecting a 4G LTE modem to other devices. In general, 4G LTE modems need to be wired to the following devices:

Distribution box: 4G LTE modem can collect data through the distribution box, so it is necessary to connect the 4G LTE modem to the distribution box.

Electricity meter: 4G LTE modem needs to collect data from the electricity meter, so it is necessary to connect the 4G LTE modem to the electricity meter.

Remote control device: the 4G LTE modem needs to be remotely controlled through the remote control device, so it is necessary to connect the 4G LTE modem to the remote control device.

Communication line: the 4G LTE modem needs to transmit data with the upper computer or cloud platform through the communication line, so it is necessary to connect the 4G LTE modem with the communication line.

The wiring of a 4G LTE modem needs to follow certain rules to ensure the correctness and stability of data acquisition, data processing, data transmission, and other operations. Common wiring rules include:

Wiring order: Wiring needs to be done in a certain order to ensure the correct connection between devices.

Wiring mode: Wiring shall be carried out in a certain way to ensure the stability and reliability of the wiring.

Wiring line: wiring shall be carried out according to a certain line to ensure the correctness and efficiency of data transmission.

It should be noted that 4G LTE modem wiring involves not only the physical connection but also the configuration of the communication protocol. For example, communication parameters need to be configured after wiring to ensure that the 4G LTE modem communicates correctly with other devices. It needs to be configured according to different application scenarios and corresponding communication protocols.

The wiring of a 4G LTE modem distribution network automation terminal is a work with high technical content, which requires a deep understanding of terminal equipment, communication lines, communication protocols, etc. Under normal circumstances, it is necessary to ask professionals for wiring to ensure the normal operation of the 4G LTE modem.

The 4G LTE modem distribution automation terminal can be installed on many different types of equipment, including:

Industrial control equipment: such as PLC, DCS, intelligent instruments, etc.

Information collection equipment: such as flowmeter, thermometer, hygrometer, etc.

Field equipment: such as field PLC, field terminal, etc.

Other special equipment: such as telemetry terminal, remote signaling terminal, remote control terminal, etc.

The specific method of installing a 4G LTE modem varies with the type of equipment and different communication protocols. Before installation, it is necessary to determine the communication parameters and protocols of the relevant equipment to ensure correct installation and normal communication.
