Abstract:

A wireless refueling controlling system based on STM32 controller and nRF24L01 wireless radio frequency transmission module is proposed for the complex wiring,high cost and scattered equipment of traditional refueling system.The system can be divided into master station (for real-time display and communication with the PC) and slave stations (for measuring parameters of oil pressure and liquid level).Master/slave stations set up wireless communication network by using Star-shaped pattern for data transmission.The test results indicate that the system works stably and realizes reliable short range point-to-multipoint wireless communication.

Key words: STM32;wireless transmission;star shaped pattern
