According to the latest data released by the Ministry of Industry and Information Technology, by the end of August 2020, the total number of mobile phone users of the three major operators of China has reached 1.598 billion, including 1.29 billion 4G users, an increase of 2.6% year-on-year. From the released public data, we can expect the current 4G user market accounts for more than 80% in China.
Even under the background that 5G frequently occupies a hot topic and has been gradually commercialized, the actual data tells us that 4G is still the mainstream of the current market. 4G is widely used in various industries, in which the industrial field applications can not be ignored.
The function of a 4G module in industrial intelligent automation control
In industrial applications, 4G is widely used in various industrial intelligent automation control equipment in the form of modules. Through the application of the 4G module, it can not only realize remote communication, real-time control, and monitoring of industrial robot, but also realize the collection and transmission of the encrypted data channel in the intranet of manufacturing enterprises through the 4G industrial wireless router, or use 4G DTU serial port RS485 / RS232 directly sends the data back to the server. Through the production monitoring room platform software, the fault information recorded by the controller command is collected and filtered.
In these processes, the 4G module is often applied to the corresponding industrial intelligent automation control equipment to achieve the above functions. Take the industrial all-in-one panel PC in the industrial robot console as an example, such as robot action command programming, running status and data, automatic reset, fault warning, etc., are set and real-time fed back through the all-in-one panel PC in the console. At this time, the application of the 4G module appears in the industrial all-in-one panel PC.
Different 4G modules can be selected for different requirements of industrial all-in-one Panel PC
In the field of industrial intelligent automation control, industrial all-in-one panel PC (also known as an industrial panel PC, industrial tablet PC) is not only used in the control of industrial robots but also covers almost all the links of heavy machinery control equipment, automatic production line, industrial big data collection, production visualization, quality inspection and so on. For the application of the 4G module, according to the industry application experience of Jawest for many years, the industrial all-in-one panel PC generally adopts the five-mode full Netcom 4G module, which has been able to meet the needs of the vast majority of users.
Based on the original properties of the five-mode all Netcom 4G module, in the application of industrial panel PC, it supports the Netcom Communication of GSM, TD-SCDMA, WCDMA, TD LTE, FDD LTE, 3G / 4G mobile network, and has the transmission characteristics of high-speed transmission and stable performance.
Jawest provides three kinds of 4G module selection requirements according to the different needs of users:
1. Data transmission;
2. Data transmission + speech;
3. Data transmission + speech + positioning.
Data transmission is equivalent to the foundation of the 4G module in the application of the industrial all-in-one panel PC. Adding speech function realizes intercom, speech software use, control, and other requirements. The positioning function is necessary for intelligent vehicle transportation, logistics, and other transportation systems. More importantly, we can customize the corresponding communication module according to the customer's communication area (supporting overseas customers' projects). In addition, Jawest industrial panel PC also supports the WiFi module and network port networking mode.
On the other hand, when it comes to networking, it is inevitable to mention 5G. At present, 5G has been put into commercial use, and the construction of the base stations is becoming more and more popular. Some experts in the industry have also said that the arrival of 5G will make the industrial Internet of things come true, not just a concept. However, from the current situation, in fact, in the field of industrial control, 4G is still the first choice of users.
Whether it is 4G or 5G, in fact, for industrial intelligent automation control hardware devices, such as industrial panel PC applications, it is just a matter of popularity. As a touch display equipment manufacturer focusing on the strength of industrial intelligent automation, the hardware equipment of Jawest product series has the application conditions of the 5G module. Only by adding a 5G module, the industrial all-in-one panel PC will support the use of the 5G networks.
Generally speaking, in terms of networking mode, the 4G module will still be the main demand module in the future. With a WiFi module and network interface, it meets the application needs of most users. As for 5G applications, we will wait and see.
