Abstract:

In order to meet the modern air-jet loom’s requirement for human-machine interaction platform, such as quick response, simple operation and scalability, a novel design of human-machine interaction system based on Win CE and CAN protocol for air-jet loom was presented in the article. Firstly, the embedded system hardware platform was designed using microprocessor EP9307 as the core; and the win CE operating system was customized. Secondly, the interface was designed using C# language, with the parameters of the system integrated; and the mechanism of data access based on the XML file was implemented. Finally, the program of CAN communication, in which multi-line technical design and Win CE interrupt mechanism were integrated, was designed based on self-defining CAN protocol, thereby realizing communication between the functional modules. A large number of test results showed that the system has good ability of interaction and communication and the characteristics of stable operation, real-time, easy expansion and maintenance.
