山地果园链式索道货运机链条拉力检测系统

为提高山地果园货运机索道的安全性能,优化货运机运行参数,以货运机链条所受拉力为安全性能指标,研究并设计了一套基于CAN总线的拉力检测系统。首先对货运机工作时链条所受拉力进行分析,确定拉力检测方案;然后用主控制器STC12C5A60S2、CAN控制器SJA1000和CAN收发器82C250等搭建拉力检测系统硬件、用Lab VIEW搭建拉力检测系统软件界面,对CAN总线通信进行可靠性检测后,对系统测量电压进行测试并标定;最后通过铁杆受力试验,检验拉力检测系统的准确度和稳定性。试验结果表明,系统测量电压最大绝对误差绝对值为0.3251 V,相对误差〈8%,标定后测量电压绝对误差绝对值〈0.0124...

Summary:为提高山地果园货运机索道的安全性能,优化货运机运行参数,以货运机链条所受拉力为安全性能指标,研究并设计了一套基于CAN总线的拉力检测系统。首先对货运机工作时链条所受拉力进行分析,确定拉力检测方案;然后用主控制器STC12C5A60S2、CAN控制器SJA1000和CAN收发器82C250等搭建拉力检测系统硬件、用Lab VIEW搭建拉力检测系统软件界面,对CAN总线通信进行可靠性检测后,对系统测量电压进行测试并标定;最后通过铁杆受力试验,检验拉力检测系统的准确度和稳定性。试验结果表明,系统测量电压最大绝对误差绝对值为0.3251 V,相对误差〈8%,标定后测量电压绝对误差绝对值〈0.0124 V;拉力检测系统对铁杆拉力测量的绝对误差绝对值〈4 N,相对误差绝对值〈5%。

In order to improve the safety performance of ropeway in cargo transporter which was used in the hill orchard, and to optimize the operating parameters of cargo transporter, a test system of pulling force with CAN bus technology was studied and designed considering the chain tension of cargo transport as the safety performance indexes. Firstly, the chain tension to determine the pulling force test program was analyzed when cargo transport was working. Secondly, the master controller STC12CSA60S2, CAN controller SJA1000 and CAN transceiver 82C250 were used to build the hardware and LabVIEW software which was used to build the user int
