Design Of Robot Multi-Function Measurement Control And Driving System Based On DSP2812

Robot Multi-function Measurement Control and Driving System is absolutely necessary in achieving the moving process. Through using this system we can realize the function that by receiving signals outside, the robot can respond accordingly. To drive DC motor, step motor, electromagnet, and so on.so this part is one of the most important element of robot skills. For the past few years, this kind of system has been paid a lot of attentions to by many engineers.In this paper we focus on how to design a multi-sensor detecting and processing robot multi-function measurement control and driving system, by using TMS320F2812 which is designed by TI as the core. In the system we use TQ2440 as upper computer and DSP2812 as lower computer. The upper computer is used to realize the function of man-machine interaction, receiving signals from the PCB which is used to catch and process the signals from the sensors, and communicating with the lower computer. As the lower computer,DSP2812 is used to realize the function of communicating with upper computer, then dealing with the data received, controlling driving the DC motor, step motor and steering engine, and receiving the data sent from Air Ultrasonic Ceramic Transducers and current sensor.The design of robot is separately and thoroughly presented in hardware part and software part in this paper. In the hardware part, I do the work in two directions, the core circuit of DSP2812 and the circuit of multi-sensor receiving and processing board. In the paper I analyze the process of designing the Minimum system of DSP2812, including the power module, FLASH, RESET module and so on. And the outer part of DSP, such as the input and output circuit of photo-couplers, the transformation circuit of UART between TTL and RS-232.On the other side, the multi-sensor connect and process circuit, I will introduce different photo-couplers and process circuit aimed at dealing with different kinds of signal. And also will introduce the circuit used to corresponding to upper computer. In the software part, I will introduce how to write code to realize the function of corresponding to upper computer, controlling the movement of DC motor and step motor, and different kinds of interrupt(such as capture unit and A/D translator),and so on,then I also finish testing the algorithm, and the result is acceptable and ideal.At the end of the article, I prospect for the development and the future of this Robot Multi-function Testing Control and Driving System, Putting forward the direction that can be improved, and the occasion which this equipment can be available.
