Monitoring System Based On The Psos The Embedded Platform Design And Realization

In many engineering applications, We need empolder embedded RTOS to settle for the Real-time and multitask application. This paper introduces a system is based PSOS, The PSOS was used very early because it's credible. This System can be run primely depend on the X86 hardware system. The PSOS can realize the task manage and attemper, it also has the function ISR,news manage,thread manage,RAM manage and Semaphore service etc.This paper will introduce a PSOS, It was application in a engineering project, The PSOS can receive ground station data from the CAN bus, then the system send the data to the receiver and the signal dispose machine by the CAN bus, The system also receive the receiver and the signal dispose machine feedback to the ground station by the CAN bus.The main work of this paper is as follows:First, we proposed a PSOS project, it can fit well to the request of the task, then we well accomplish the hardware design of the system. The hardware design include CPU,SRAM,CAN bus,A/D convertor,interrupt and IO addresses distribute.Secondly, we well process the software design, based on the requirement, we will write code to realize the function of this application. This part is the emphases of this paper. This part include the Board Suspensory Package's(BSP) design and the application layer's design. The BSP main to finish the hardware's initialization, the timer's initialization and the 6 CAN buses's initialization. application layer code will manage the tasks, the tasks include receiving The datas,Unpacking the datas,coding and executing the commands,sending the TASK DATA,quering the remote parameters.Thirdly , we finished the system debugging. This chapter main introduce the debugging environment of the software, and also describe the step of the debugging, and the problem we have met, The Debug include the CAN bus receiving and transmiting,A/D conversion,EEPROM's reading and writing,the timers and the series port's test. In conclusion, this paper presents through the use of the hardware circuit design based on PSOS and the software realization, the development of projects to meet the requirements for the project. This system was applied in the project stably and reliably.
