What is Industrial 4G LTE modem?

Industrial 4G LTE modem is an intelligent terminal mainly used for communication between devices in the Internet of Things (IoT) era. Industrial 4G LTE modems typically come in standard package designs. It can be widely used in intelligent Internet of Things applications such as automobile airbag control system, elevator monitoring system, automatic fire extinguishing system and so on. Industrial 4G LTE modem is a scalable network communication device consisting of one or more groups of serial ports and some peripheral devices. In the process of connection and control, it can realize various data acquisition, such as communication signal transmission, remote monitoring and alarm functions.

1. Industrial Internet of Things monitoring system

The Internet of Things monitoring system is a distributed automation composed of control center, computer, wireless sensor network and industrial control.Network. Monitoring personnel can remotely monitor industrial equipment through smart phones or computers, mobile terminals and other terminals.Every industrial equipment in the monitoring system is real-time, and the data is uploaded to the background server through the network. Through the remote information processing technology, the analysis and judgment of the operation status and abnormal data of industrial equipment are realized. Users can grasp and control the running state of industrial equipment in time, and make corresponding processing work according to user instructions. 

The system is mainly composed of Industrial 4G LTE modem and wireless sensor network.It can carry out all-round and all-weather remote detection of all kinds of equipment.It provides users with real-time, dynamic, comprehensive, intelligent, reliable and other information data acquisition functions. In the industrial Internet environment. Users can get all kinds of data through the wireless sensor network and upload them to the background server for analysis or judgment. The system can effectively solve the problem of information asymmetry among the devices in the factory,It realizes real-time acquisition and monitoring of key data such as industrial equipment status and operation status. At present, with the wide application of Internet of Things technology and intelligent terminal technology in all walks of life. Industrial 4G LTE modem can provide users with remote control information and security protection functions in many situations. At the same time, the system can also realize various remote monitoring and alarm functions, effectively reducing the time of manual inspection and management. And that risk of potential safety hazard is reduced. 

2. Vehicle remote monitoring

Scenario 1: Vehicle remote monitoring: on-board camera/audible and visual alarm, steering wheel power system.Car audio/GPS, engine water temperature sensor (water temperature, intake air temperature). Vehicle remote monitoring system is an intelligent terminal for vehicle safety, which can collect real-time data from the vehicle recorder in the process of driving.And transmit that data to a vehicle networking server for remote management and alarm.It plays a vital role in the safe driving of vehicles.

Scenario 2: Vehicle intelligent network system: vehicle automatic driving, car sharing, traffic congestion relief, road rescue, etc. In these applications, intelligent networking is the core component. Vehicles in the intelligent network system can drive automatically and share information in the cloud in real time. These systems can provide drivers with various humanized services and humanized functions, such as voice recognition.

Scenario 3: Logistics monitoring and management system: The informatization of the logistics industry is the foundation of the informatization of logistics enterprises. With the rapid development of China's national economy, social resources are constantly inclined to the logistics industry.

Logistics activities produce a large number of large, diverse and interrelated logistics information data and transport behavior data. These data are difficult to achieve real-time statistics through traditional paper documents and various technical means. It is also difficult to carry out accurate analysis and management. The analysis and processing of these data need to be completed by professional analysis software and need a long time of manual intervention. The vehicle Internet of Things platform based on RFID technology can match the internal information of the vehicle with the external equipment information in real time. And connect via Bluetooth or Wi-Fi. At the same time, it can carry out remote monitoring and management and remote diagnosis of vehicles. A vehicle remote monitor system is a complete system. Comprises a vehicle positioning system, a driving recorder, a wireless sensor network, an information terminal, a software management platform and other elements.

3. Intelligent mine monitoring

● Frequent mine accidents, mine safety issues can not be ignored. Intelligent mine can grasp the dangerous situation underground in real time through monitoring system, so as to achieve "advanced prevention".

● Safety production guarantee: real-time monitoring of underground operation, early warning and timely handling of potential safety hazards.

● Underground environment monitoring: realize monitoring, data uploading and statistical analysis of monitoring data among multiple equipment.

▲ Coal mine underground system monitoring: support on-site monitoring and remote control. Realize the real-time monitoring and alarm function of the water circulation state.

▲ Monitor the operation status of underground power supply and ventilation system and other important equipment in coal mine: support the monitoring of underground key equipment such as water pump and fanAnd the like to carry out real-time remote monitoring and control, and carry out real-time monitoring and control on the power supply system and the ventilation system in the mine.

▲ Coal mining: collect underground coal mine data information through 4G LTE modem, and realize intelligent transmission and management. The main application scenarios of the mine include:

● Remote centralized monitoring;

● Coal mining site data collection;

● Fire safety such as automatic mine fire alarm;

● Remote monitoring of safety production process;

● Safety management such as personnel positioning, safety inspection and equipment management in the coal mine.

4. Automatic fire extinguishing

Automatic fire extinguishing system refers to the automatic fire extinguishing system in case of fire. Automatic fire extinguishing devices based on gas fire extinguishing can detect the change of carbon dioxide content in the air. And that extinguish agent driven by the gas is sprayed to the fire scene so as to achieve the purpose of put out the fire.

Generally, automatic fire extinguishing is carried out by means of liquid level alarm and gas fire extinguishing linkage. Common Industrial 4G LTE modem products include intelligent instruments, sensors, fire controllers, etc. It is mainly used for monitoring and alarm functions, and alarm display through parameters such as temperature, humidity and carbon dioxide concentration collected on site. At the same time, the types and concentrations of gases in the fire area are analyzed and judged. Industrial 4G LTE modem does not need to set up complex communication protocols in the communication process. It has the characteristics of high reliability and low power consumption, which can meet the needs of data transmission and exchange between multiple systems.
