| 中文摘要: |
| 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LabVIEW 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%。 |
| 英文摘要: |
| 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 STC12C5A60S2，CAN controller SJA1000 and CAN transceiver 82C250 were used to
build the hardware and LabVIEW software which was used to build the user interface of the pulling test system. And
then，the measuring voltages of the pulling test system were tested and the voltages were demarcated after testing the
communication reliability of CAN bus. Finally，the accuracy and stability of pulling test system were tested through the
pulling test of gavelock. Results showed that the absolute value of the maximum absolute error in the measuring voltage
was 0.3251 V and the relative error was less than 8%. After calibration，the absolute value of the absolute error in the
measuring voltage was less than 0.0124 V. The absolute value of absolute error in the pulling test of gavelock was less
than 4 N，and the absolute relative error was less than 5%. |
