A system of data acquisition and remote wireless transmission based on PIC kernel and embedded FreeRTOS was designed, in order to meet the needs of real?time monitoring system for radiation dose. The related hardware circuits were designed by using PIC24FJ128GA106 micro controller which consisted of PIC24 core and ME3000. It achieved management of hardware resources and schedule of some tasks through transplant FreeRTOS. This system simplified the complexity of hardware design, optimized software performance, improved reliability of the system and reduced costs.
