| 摘 要： | 为提高路面摊铺平整度,研究了一种基于CAN总线的多点(多探头)非接触式摊铺机自动找平系统,给出了系统总体结构、CAN节点的硬件电路及软件主要流程,采用多重滤波方法进行数据处理,滤除摊铺机作业过程中偶然因素造成的跳点数据,提高系统的抗干扰性能。采用该找平系统对单探头和多探头找平方式进行了对比试验,结果表明多探头方式找平效果优于单探头方式;与接触式自动找平系统对比实验表明采用该找平系统中面层平整度平均值较接触式提高了3.2%,上面层提高了7.8%。

| Abstract: | In order to improve the smoothness of road paving,a multi-point(multi-probe) non-touching auto-leveling control system based on CAN(control area network) bus was developed,the structure of the system,the circuit of CAN node and the main flow charts of CAN node software were given,multi-filtering algorithm was employed to eliminate the wild data during road paving process,so that the disturbance attenuation performance of the system was improved.Comparison test result shows that the leveling effect of multi-probe is more effective than single-probe.Compared with touching auto-leveling system,the paving smoothness of intermediate surface layer is increased by 3.2%,and upper surface layer by 7.8% with the system.1 tab,(7 figs,) 11 refs. |
