The collection and transmission module developed by Zongheng Intelligent Control mainly uses 4G network as the transmission channel, which can realize the mutual transmission of data between serial devices and network servers through the operator’s network. Currently, it can be roughly divided into two categories of products . The first category is pure transparent transmission. , the second type is a transparent transmission function with multiple interfaces and band control .
1. Pure transparent transmission (4G DTU)
Compatible with Modbus RTU/TCP protocol and JSON. With “remote control” as the core function and high ease of use, users can easily and quickly integrate it into their own systems to achieve remote and local control based on LTE and RS485.

2. Transparent transmission and control
Compatible with Modbus RTU/TCP protocol. With “remote control” as the core function and high ease of use, users can easily and quickly integrate it into their own systems to achieve remote and local control based on LTE and RS485. Supports local logic operations , wet and dry node detection and other functions.

Traditional CNC equipment has low efficiency, high energy consumption, and extensive management. With the deepening of changes in the manufacturing industry, the balance between supply and demand of production materials has been broken. Under this situation, refined production methods have attracted more and more attention from the majority of producers. To meet market challenges, advanced, reliable, flexible and economical manufacturing tools are an important support for the manufacturing industry to achieve sustainable development advantages. The extensive and in-depth application of CNC machining technology has become an important way for factories to improve their production technology level.
Whether data transmission is advanced, reliable, and compatible is one of the main concerns of CNC machining technology. The link mode of data transmission can be divided into wired link and wireless link. Common CNC equipment data transmission hardware interfaces mainly include: serial USB, RS232, or PC card. Data transmission technology is also an important link in the technological transformation of CNC machine tool processing management and other aspects. Using infrared remote transmission technology for encoding/decoding data transmission has many advantages. It meets the requirements of anti- interference, transmission security, stable performance and excellent compatibility. Especially in terms of economy and maintenance, it has outstanding performance.
