Abstract
Over the last decade, with the rapid development of mobile communication technology, an increasing number of information collection and remote control system adopts wireless data transmission technology, it mainly has the advantages of low cost, easy installation, easy movement compared with the wiring data-transmission, so it is widely used in automotive electronics, environmental monitoring, electrical and automation field.
This text researched and analysed the principle of wireless data transmission and the realization of the method, and designed a microcontroller-based embedded wireless data acquisition and control system. The system has the functions of data acquisition, monitoring the temperature, automatically operating the motor, wirelessly transmitting the data. The system is composed of motor control module, data acquisition module, wireless transmission module, computer interface module. During the designing process, it adopted the modular design concept, so it make the design structure clarity, high dependability, easy debugging. This article also completed the software of the upper computer and subordinate computer at the same time, and it adopted the design opinion of structuring, so it has the advantage of well program transplanted, code reasonable optimized and run efficiently. The function of the system is equipped, it has not only the function of wireless data acquisition and display the data, but it also can control the motor directly. The system is simple, reliable, man-machine conversation friendly, high automation.. By experiment, it shows that the accuracy of the system is very high, the data transmission is accurate, well realized the functions of motor automatic control and data acquisition.
