4G LTE modem, also known as data transmission unit, refers to a device that collects, transmits, stores and controls data through a wireless communication network. In recent years, the rapid development of the Internet of things technology has changed people's way of life, and 4G LTE modem, as an indispensable part of the Internet of things, has been applied more and more widely.
4G LTE modem IoT sensor data acquisition
In the Internet of things, 4G LTE modem is closely related to sensors. Sensor is an important part of the Internet of Things, which can convert various physical quantities into digital signals, such as temperature, humidity, pressure, flow and so on. The 4G LTE modem can transmit the data collected by the sensor to the cloud to realize remote monitoring of the data.It has many applications in agriculture, environmental protection, smart home and other fields.
In some IOT automation system scenarios, it is necessary to monitor the target data and control the equipment and instruments, and 4G LTE modem can realize this process well. The data is transmitted to the cloud through the wireless network, and the real-time monitoring and control of the data are realized. If there is an abnormal situation, the 4G LTE modem will send instructions to the device side through the cloud to tighten
4G LTE modem and remote monitoring
Another important application of 4G LTE modem is remote monitoring. The traditional monitoring system needs a monitoring center and a control center, but 4G LTE modem can realize the collection and transmission of sensor data, and can also realize remote control, which is of great significance to security monitoring, automatic control and other fields.
Taking urban security as an example, 4G LTE modem can realize the collection and transmission of video, sound, image and other data, and realize real-time monitoring and control of data through the cloud. In the field of environmental monitoring, 4G LTE modem can realize remote monitoring of pollution sources and reduce the harm of environmental pollution to human beings and nature.
The 4G LTE modem is responsible for the following functions:
1. Data collection and transmission: 4G LTE modem can collect data through field sensors or instruments and transmit them to the remote monitoring center or cloud platform through the network (such as 4G, 5G, Ethernet, etc.). It can compress, organize and encapsulate the data of field devices, transmit them in the network and ensure the safety and reliability of the data.
2. Communication protocol conversion: 4G LTE modem can perform protocol conversion on the data collected by field devices, so as to be compatible with the standard communication protocols (such as Modbus, OPC, etc.) used by the remote monitoring center or cloud platform, and ensure the correct analysis and transmission of data.
3. Remote control and configuration: 4G LTE modem can also receive the control command or configuration information sent by the remote monitoring center or cloud platform, and transmit it to the field device for corresponding operation to realize remote control.
4. Data processing and storage: the 4G LTE modem can perform simple processing (such as data cleaning, calculation, etc.) And storage on the collected data for further use and analysis by the remote monitoring center or cloud platform.
The 4G LTE modem is the bridge between field data transmission and remote monitoring in the remote monitoring system, which is responsible for data acquisition, transmission, protocol conversion and remote control. It is closely related to the remote monitoring system. Through the transmission and processing of data, it realizes the remote monitoring and management of field equipment.
With the continuous development and maturity of the Internet of things technology, 4G LTE modem will be constantly updated and iterated in the application. At present, the rapid development of cloud computing, artificial intelligence, big data and other technologies provides more possibilities for the application of 4G LTE modem.In the future, 4G LTE modem will play a more important role in power, energy consumption control, smart city, vehicle monitoring and other fields. Its functions will be more powerful, such as automatic control, intelligent recognition, adaptive learning and so on.
