The wireless data transmission module mainly includes two aspects functions: data transmission multi-channel control. In some industrial control sites, corresponding software at the transmitting end and the receiving end should be written for file format conversion. Transmitting module and receiving module are implemented when multi-channel parallel control is required in some control situations.
With the development of the market, the demand for wireless data transmission modules is also increasing. What are the advantages? Let us take a look at the following:
The establishment of wired communication methods must erect cables or dig trenches, so it requires a lot of manpower and material resources. However, use wireless digital radio stations to establish dedicated wireless data transmission methods only needs to connect each terminal to the station and raise appropriate heights antennas. In contrast, wireless data transmission mode
saves manpower and material resources, and its investment is quite economical.
The engineering cycle may take several months When remote stations connect to each other which distances of several kilometers to tens of kilometers through wired transmission.
The digital wireless transmission module’s engineering cycle can quickly set up communication link, and it will only take a few days or weeks.
Wired communication has many limiting when encountering special application environments, such as special geographical environments like mountains, lakes, and forest areas, or applications where wiring is difficult, such as moving objects.
Wireless data transmission module will not be subject to these restrictions, so it has better adaptability, almost no geographical restrictions.
If the user has set up a communication network, new devices are required to be added according to the needs. Adopting wired method will re-wire or may damage the original communication line, which is troublesome.
And wireless data transmission only connects the newly added equipment to station, which has better expansibility.
