Mobile Robot Collecting Information With Anti-jamming Based On CPLD

In the mobile robot technology related to research, navigation technology is its core, in practical application, simply guide the path on the road to draw lines, the robot can through visual navigation system to control their own walk. The topic for the front of the robot controller input signal for research. Based on the input signal and set up the structure of the input signal interference to the controller handling the importation of real-time, accurate, high-speed, the stability of the image information, for the path tracking system to provide a guarantee.The subject of the inquiry in the mobile robot in the process of collecting information processing, the first integrated circuit structures with hardware circuits required by the CCD timing pulse. Then CPLD structures robot image acquisition hardware circuit, and then guide lines on the surface of the image data acquisition. Finally, the collection of information dealing with anti-jamming. The signal filtering, detection, forecast, widely used to filter. One digital filter with high stability, high accuracy and design flexibility, and convenience, and many other prominent advantages and avoid a simulation of the filter can not be overcome by the voltage drift, drift and noise and other issues, as a result of the development of digital technology, Digital technology filter function more and more people's attention and a wide range of applications.In this paper, through the revision of the biggest noise on the width of the filter out noise can be achieved, a saving of the hardware resources, greatly improving the system of flexible and economic lines. It also can be filtered out by comparing the two types of noise filter. In practical application, also proposed the use of FIR filter more practical significance, in order to better verify the accuracy of the simulation results, the text of the joint MATLAB and VHDL simulation of the circuit design of the simulation test results to design specifications. The simulation results show that the design of the filter paper hardware smaller, the DA is designed to improve the development of a method to improve the system clock frequency of 100 MHz to achieve the above. Just look at the same time table and make the appropriate changes, respectively, will be able to achieve low pass, high-pass, band-pass FIR filter, reflects the design flexibility.
