Wireless data transmission radio is the abbreviation of digital wireless data transmission radio. Wireless data transmission radio is an early communication method developed in the communication industry and is also a relatively mature wireless communication technology. Data transmission radio is suitable for various point-to-point and point-to-multipoint wireless data transmission systems, such as power load monitoring and distribution network. Automation, hydrology and water regime forecasting, water pipe network monitoring, urban street light monitoring, air defense alarm control, railway signal monitoring, railway water supply centralized control, oil and gas pipeline network monitoring, GPS positioning system, remote meter reading, electronic hanging scale, automatic Target reporting, earthquake forecasting, fire prevention and theft prevention, environmental monitoring and other industrial automation systems.
Wireless data transmission radio network
Point-to-point data transfer
User serial port device A is connected to the master station 01 through the 232/485 serial port, and user device B is connected to the slave station 02 through the 232/485 serial port. Basically, without any other complicated configuration, the data of the user’s serial port device A/B can be transmitted to Serial device B/A.
Point-to-multipoint data transmission
User serial device A is connected to the master station 01 through the 232/485 serial port, and user serial device B/C/D is connected to the slave station 02/03/04 through the 232/485 serial port. Basically, no other complicated configuration is required to realize the user The data of serial port device A is transmitted to serial port device B/C/D, and the data of serial port device B/C/D is transmitted to user’s serial port device A.
