Introduction to RF wireless module

The RF wireless module,which is a modular product of digital data transmission radio, refers to a high-performance professional data transmission radio module realized by DSP technology and radio technology. The RF wireless module extends to many systems, industrially controlled switching io devices, 485 wireless transmission devices dw-m1, analog acquisition and control devices. From the use of the earliest button code, telegram, analog radio module plus wireless MODEM, to the current digital radio module and DSP, software radio; transmission signal also from code, low-speed data (300 ~ 1200bps) to high-speed data (N * 64K ~ N*E1).

Typical applications include industrial automation, oilfield data collection, railway wireless communications, coal mine safety monitoring systems, pipe network monitoring, hydrological monitoring systems, and wastewater treatment monitoring.

Wireless module features

1. The cost is cheap

The establishment of wired communication methods must erect cables or dig trenches, so it requires a lot of manpower and material resources. The use of wireless digital radio stations to establish dedicated wireless data transmission methods eliminates the need to erect cables or dig cable trenches, and only needs to be connected at each terminal. Wireless data transmission stations and antennas with appropriate heights are all available. In contrast, the use of wireless data transmission module to establish a dedicated wireless data transmission mode, saving manpower and material resources, investment is quite economical.

Of course, in some close-range data communication systems, wireless communication methods are not cheaper than wired methods, but sometimes the actual field environment is difficult to route, and customers will use wireless methods to achieve communication according to the needs of the on-site environment.

2. Short construction period

When remote stations connecting distances of several kilometers to tens of kilometers are to be connected to each other, wired lines must be used to erect long-distance cables or to dig long cable trenches. This engineering cycle may take several months. The digital transmission module uses the digital transmission module to establish a dedicated wireless data transmission mode. It only needs to set up an antenna of appropriate height. 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.

3. Good adaptability

The limitations of wired communication are too great. When encountering special application environments, such as encountering special geographical environments such as mountains, lakes, and forest areas, or applications where wiring is difficult, such as moving objects, the wired network will be Wiring engineering has a strong constraint, and the use of wireless data transmission module to establish a dedicated wireless data transmission method will not be subject to these restrictions, so the use of wireless data transmission module to establish a dedicated wireless data transmission method will be better than wired communication. Adaptability is almost unrestricted by the geographical environment.

4. Good scalability

After a user has set up a communication network, new devices are often added because of the needs of the system. If the wired method is used, it needs to be re-wired, the construction is troublesome, and it may damage the original communication line. However, if the wireless data transmission station is used to establish a dedicated wireless data transmission method, only the newly added equipment and the wireless data transmission station need to be added. Connected to achieve system expansion, compared to better scalability.

5. Equipment maintenance

The maintenance of the wired communication link needs to be checked along the line. When a fault occurs, it is generally difficult to find the fault point in time. The wireless data transmission module is used to establish a dedicated wireless data transmission mode. Only the data transmission module needs to be maintained, and when the fault occurs, the fault can be quickly found. The reason is to restore the normal operation of the line.

The disadvantages of wireless data transmission compared to wired communication: reliability needs to be improved and affected by the environment.
