| For more and more cables are used in the fields of construction and industry, most of which are in different diameter, the problem of inspection and maintenance for these cables has been booming. Although it has been researched and analyzed for a long time and also made some progress, there is seldom breakthrough on the topic of minimization, reliability and adaptability. Here is a paper that emphasizes on researching the relevant technology of constructing a reliable, minimized and stable droved cable inspect robot.According to the needs of application, we work out the corresponding requirement of design, analyze and choose one from different plans. By reasonably simplify the model of driven system, we analyze, calculate and design this part which is based on step-motor. After a completely compare with other human-machine communication means, we choose the wireless module to fulfill the requirements of system such as reliable and minimized. At last we choose the embed solution for the controller after adequate discussion and analysis, and construct system by selecting some functional module and chips. For the hardware realization of controller, there are two main sections as follow: analyzing and fulfilling for the circuit of hardware; designing for the printed circuit board (PCB) on Electromagnetic Compatibility (EMC).Here we analyze and expound for the key parts which play a important role in property of the controller, such as power supply circuit, reset circuit, interface circuit of encoder and driven circuit for step-motor. On the basis of electromagnetics, we have analyzed the property of microstrips in high frequency PCBs and designed for the capacitance which are used to bypass the energy of RF or minimize the coupling, matched of characteristic impedance for transmission lines, modeled and analyzed the crosstalk between two parallel lines, searched for the reason of radio frequency interfere (RF) and also the effective solutions. Embed system is the combination of hardware and software, here we analyze the flow of key functional realization, and construct the software system by packaging the function of MCX314.Simultaneously we enhanced the reliability of system by setting limit value for the times handling synchronization in the software.By the analyzing and designing described above, we obtain some effective parameters and the reliability of controller has been promoted obviously and is favorable for the purpose of stable drive for the whole system. |
