Study of signal measurement and data transmission based on singlechip and CAN bus

介绍了利用单片机测量信号的时间长度和利用CAN总线技术进行数据信息传输的方法、硬件接口电路及相应的软件应用程序及其在直升机旋翼共锥度测试系统中的应用.该方法在直升机上的应用从根本上改善了以往直升机旋翼共锥度测试中信号传输速度慢、稳定性差、误码率高的缺点,将传统的模拟传输改进为更可靠的数字传输,为直升机旋翼测试的顺利进行提供了保障.

This paper mainly describes the method of measuring the time length of signals using singlechip and transmitting data information using CAN bus technology. This method overcomes the disadvantages of helicopter blade running elevation measurement, for example, slow signal transmission, bad stability and the high error code rate. The traditional analog circuit is transformed into the more reliable digital circuit, guaranteeing the helicopter blade running elevation measurement to go with a swing.
