Wireless data transmission module

What are the advantages of wireless data transmission module Introduction to related knowledge of wireless communication module

　　 The wireless communication module is a key link connecting the perception layer and the network layer of the Internet of Things. It belongs to the underlying hardware link and is irreplaceable. There is a one-to-one correspondence between the wireless communication module and the Internet of Things terminal.

It is the key link between the perception layer and the network layer of the Internet of Things. The device data generated by all the terminals of the Internet of Things perception layer needs to be aggregated to the network layer through the wireless communication module, and then the device can be remotely controlled through the cloud management platform. At the same time, after data analysis, Bring the improvement of management efficiency.

　　The main function of the wireless communication module:

　　Communication function: support GPRS and short message dual-channel data transmission; support multi-center data communication.

　　 Collection function: Collection of serial device data, such as serial instrument, collector, PLC, etc.

　　Remote management function: support remote parameter setting and program upgrade.

　　Characteristics of wireless communication module:

　　Industrial grade design, suitable for harsh outdoor environment.

　　Built-in hardware and software watchdog, no crash, no disconnection.

　　 supports transparent data transmission.

　　 supports domain name resolution function.

　　 Support various configuration software and users to develop their own software systems.

　　In comparison, using a wireless data transmission module to establish a dedicated wireless data transmission method has the following advantages over other methods:

Wireless communication module

　　 Cheap cost

The establishment of the wired communication method requires the erection of cables or the excavation of cable trenches, so a lot of manpower and material resources are required; while the use of wireless data transmission stations to establish a dedicated wireless data transmission method does not require erection of cables or digging of cable trenches, and only needs to be connected at each terminal A wireless data transmission station and an antenna of appropriate height are sufficient. In contrast, using the wireless data transmission module to establish a dedicated wireless data transmission mode saves manpower and material resources and saves investment.

　　Of course, in some short-distance data communication systems, the wireless communication method is not less costly than the wired method, but sometimes the actual field environment is difficult to wire, and the customer will still choose the wireless method to achieve communication according to the needs of the field environment.

　　The construction period is short

When connecting remote sites that are several kilometers to tens of kilometers apart for communication, using wired means, long-distance cables must be erected or long cable trenches must be dug. This engineering cycle may take several months. With the digital transmission module to establish a dedicated wireless data transmission method, you only need to set up an antenna of an appropriate height, and the engineering cycle only takes a few days or weeks. In contrast, the wireless method can quickly set up a communication link. The cycle is greatly shortened.

　　 good adaptability

The limitations of wired communication are too great. When encountering some special application environments, such as special geographical environments such as mountains, lakes, forests, or mobile objects and other application environments where wiring is difficult, it will be difficult for wired networks. The wiring project has a strong restriction, and the establishment of a dedicated wireless data transmission method with a wireless data transmission module will not be subject to these restrictions. Therefore, the establishment of a dedicated wireless data transmission method with a wireless data transmission module will be better and more extensive than wired communication. The adaptability is almost not restricted by the geographical environment.

　　 good scalability

　　 After the user has established a communication network, new equipment is often added due to the needs of the system. If you use a wired method, you need to re-wiring, the construction is more troublesome, and it may damage the original communication line, but if you use a wireless data transmission station to establish a dedicated wireless data transmission method, you only need to connect the new equipment with the wireless data transmission station. The expansion of the system can be realized by connecting, which has better scalability in comparison.
