Because of the high accuracy and being easily installed, the positioning technique using coding cable has been widely used for the orientation of three cars in the coke plant. In the coke field, there is much more noise and disturbance, which will greatly affect signal process and obstruct the operation of the positioning system. For this reason, this paper presents a way to design a band pass filter that satisfies the demand of the positioning system based on an integrated active filter chip——MAX275. The paper analyzes the MAX275 chip structure and the design method based on MAX275. According to the demand of the positioning system using coding cable, a band pass filter is designed. After digital simulation experiment, it has been used in the three cars' orientation in coke plan and the application result shows that it filters noise and disturbance effectively and works well.
