The Design and Implement ofIntelligent Thread-checking Device Based on CAN Bus

A solution of design and implementation for intelligent thread-checking device based on CAN bus is qiven in this paper.Field programmable gate array chips and AVR microprocessors are used in intelligent thread-checking device.CAN bus is applied to the communication and interlink age between computer and thread-checking module.The design of this paper can recognize the expansion of hardware of thread-checking modules on great quantity socket terminal of test measurement and specify the quantity of socket terminal with the software.It also can solve availably problems that the past thread-checking device are devoid of flexible and lower expand.It can adapt multifold situation to meet diverse requirements,and a new solution to check the electrical connection between the kinds of cables is provided.
