What are the advantages of Jrepus 4G DTU weighing system wireless monitoring system

1.System background

When the iron and steel enterprises were small in scale at the beginning, the requirements for the weighing system were relatively simple. However, with the continuous rise of the Internet age, the iron and steel enterprises continue to prosper and develop. Sales metering work. The original weighing system only has a simple weighing function, lacks anti-cheating measures, and has many human factors, which has brought a lot of losses to the enterprise. Secondly, the original weighing system uses a microcomputer as the system, and the core stability is poor. The working environment is relatively harsh, and machine failures are prone to occur, causing vehicles to fail to weigh, seriously affecting production and sales. Moreover, the location of each weighing room is scattered, which is not conducive to centralized management. It is difficult to collect data, and it is impossible to understand the production and sales of the enterprise in real time. The seamless connection between the network and the service center realizes the centralized management of the weighing room, real-time data transmission, more accurate and more real, and the whole system can better adapt to various complex industrial environments in different weighing industries .

 3. System composition

The whole weighing system is mainly composed of truck scale, load cell, Jrepus 4G DTU, firewall, server, data center and other main parts. /3G/4G wireless network transmits the 4-20MA analog data acquisition to the server and data center, and the server and data center extract and analyze the returned data through the system software, so as to obtain accurate and effective weighing data, which is beneficial to Improve the production and sales efficiency of enterprises.

4. System advantages

● Real-time collection of weighing information and centralized management. The service center forms a summary table by weighing point by collecting the weighing information of each weighing point, and makes production scheduling based on this, balances the shipments of each weighing point, and improves the group company's profit. Sales Outbound Efficiency.

● Weighing personnel stay away from the weighing site, which increases the transparency of business operations, eliminates the existence of human factors in the weighing process, and helps enterprises reduce unnecessary losses.

● The speed of information collection is fast, and the entire system can realize rapid weighing through the wireless network, which improves the efficiency of weighing and avoids the phenomenon of queuing and overweighting.

● Industrial-grade equipment, suitable for various responsible application scenarios, high stability, and conducive to unattended applications. 

5. Significance of wireless transmission in weighing system

Under the current market conditions, most of the weighing instruments are still used alone, and the connection between the instruments is not very close. When it is necessary to perform data processing on the weighing platform, it is often used to connect the instrument to the large screen by using the current loop method, to connect a single instrument to the computer at close range by using the RS-232 method, or to connect multiple instruments by using the RS-485 method. The instrument is connected with the computer. There are the following inconveniences in this conventional connection method:

(a) The connection between the weighing instrument and the computer and other accessories requires wiring, and it is difficult to choose between the concealment of the wiring and the convenience of maintenance.

(b) Various interfaces have requirements for the length of the connection and the number of loads, and the load capacity must also be considered.

(c) When the wiring is long, it is easily affected by the interference of the on-site environment, especially in the case of harsh electrical and electromagnetic environments.

In terms of wireless transmission, there are multiple wireless transmission methods coexisting. Some of these methods are relatively mature; some methods may already have relatively mature application solutions in other industries, but they may still be in the experimental stage in the weighing instrument industry. Through the use of ordinary RF wireless transmission, Zigbee wireless transmission, GSM/GPRS wireless transmission and other methods, the weighing instrument, weighing platform, data processing server, and large-screen display and other accessories are closely connected remotely. Therefore, wireless transmission has great advantages over conventional wiring methods when the distance is long, the load is large, and the environment is harsh.
