The Research Of Sensor Network Nodes Based On Embedded MPU

This paper is mainly about the research that based on the 32-bit embedded RISC microprocessor LPC2210 and the embedded real-time operating system μC/OS-II in the digital temperature sensor system, and describes the application and realization methods. It integrates the high capability, low powered 32-bit RISC structure processors of ARM kernel, and public source code embedded real-time operating system μC/OS-II, constructs integrative hardware based on LPC2210, Sensor and PC, and then transplants embedded real-time operating system μC/OS-II to achieve the exploitation of digital temperature sensor system application. Recent years, with the development of the advanced technology of microprocessors, more and more embedded systems are built by embedded microprocessors instead of currency processors.The ARM processor is a 32-bit embedded RISC microprocessor which is recognized the leader in the field, The software platform can use the real-time operating system μC/OS-II, μC/OS-II is integrated transplantable ensolidified reducible and pre-empt real-time multitask kernel, and now it has been used in more than 40 kinds of microprocessors up.The node of the sensor platform is composed of sensor, microprocessor, transceiver and upper-machine in this design. The distributed note is able to sense various information, which transmit processed dates to host computer, then the host deals with the dates and displays correspondly, which is also communicated with other nodes at the same time.
