Wireless data transmission

Wireless Data Transfer Overview

Wireless data transmission refers to remote transmission of data output from industrial field devices or various physical quantities using wireless digital pass modules, and can be used for wireless analog acquisitions. Perform wireless switch control, if the transfer is transferred, remote device telemetry remote control can be done. Wireless data transmission can be completed by the following devices:

private network: digital pass station, broadband WiFi.

public network: GPRS, 3G, 4G network.

Other.

Technical Introduction

Wireless data transmission is usually DTD433M band, which can provide high stability, high reliability, low cost data transmission. It provides a transparent RS232 / RS485 interface with convenient installation and maintenance, strong diffraction capability, flexible network structure, large-scale coverage, suitable for applications such as points, complex and complex geographical environment.

The device provides point-to-point communication, or you can implement point-to-multipoint communication, no need to write a program, no wiring is required. General electrical commissioning can also be passed. Wireless data transmission devices are widely used in wireless data, typical applications include remote control, remote sensing, data acquisition, detection, alarm, process control, etc. in telemetry systems.
