Traditional factory people are the absolute main force, and every production process is completed by people. This not only has low production efficiency but also high cost. Factory intelligence will be the only way to enhance the competitiveness of enterprises. ZM470SX industrial-grade LoRa communication module can perfectly liberate workers, improve production efficiency and easily help the factory to be intelligent.
1 traditional factory locust
1. Things must be close, three differences and five wrong
Traditional industrial production relies almost entirely on manual acquisition of equipment production data. The flow of people and scattered data has made the preservation of data a huge problem. At the same time, the low efficiency of manual statistics can also cause problems such as inaccurate data and poor timeliness. All problems will lead to an increase in operating costs, and backward data management will undoubtedly become a “locust†of the factory.
2. There is no way in the sky, no door to the ground
In addition to data management issues, the frequent failure of equipment is also a major pain point in traditional factories. Unexpected failure of the equipment not only causes the stagnation of production, but also the invisible damage caused to the equipment is immeasurable. It's hard to imagine the terrible consequences of downtime for two hours and millions of dollars. The device's illness is not reported to the manager, and the device naturally strikes when the level of failure becomes more serious. The traditional shift inspection mechanism not only causes the labor loss of the factory, but also many problems cannot be directly discovered, and these hidden dangers may eventually lead to bad consequences.
2 Guardian of the Smart Factory
ZM470SX series module is an industrial grade RF wireless product independently developed by Guangzhou Zhiyuan Electronics Co., Ltd. The module is designed with LoRa modulation technology derived from military tactical communication system, which perfectly solves the problem of ultra-long-distance communication and security and stability of small data in complex environments. It is widely used in various application fields, especially for motor and industrial control. occasion.
The application of ZM470SX-M in the smart factory is shown in the following figure. The application of LoRa technology in smart factory is briefly summarized by taking the piece data uploading, equipment fault reporting and environmental temperature and humidity status monitoring as examples.
The piece counting data collected by the sensor, the switching signal of the equipment operation and the ambient temperature and humidity data are transmitted to the respective ZM470SX-M modules, and then uploaded to the gateway through the established LoRa network, and the gateway then summarizes the data to the server separately. When the device starts to have a hidden danger, the switch letter will be abnormal and will alarm. The administrator can log in to the web server through the browser to check the production status, and can also know the situation at any time through the mobile app.
In addition to the simple applications described above, the ZM470SX-M module can be added to all aspects of the production process to ensure data accuracy and real-time, helping managers to keep track of production, reduce production costs, increase production efficiency, and easily assist.

4ZM470SX series module interface resources
The ZM470SX series module uses the SPI interface as the slave to connect with the user MCU. The antenna is taken out from the module pins. Users can connect various types of antennas according to the actual needs of the product. The module defaults to no antenna at the factory. When using the antenna with non-standard interface, please pay attention to the matching with the product's outer casing and structure. If necessary, please contact our company and use the RF simulation laboratory for matching debugging.
