The technical problem that the utility model needs to solve is to improve the communication ability between the walking car and the central control system of the workshop, so as to realize the whole process feedback and monitoring of the car on the assembly line. Therefore, the utility model provides a distributed control system to the car, including the vehicle module, a track and a sliding contact line and a central control module, car module through the collector and sliding contact line contact, technical scheme, between the central controller and the sliding contact line and between the controller and the electric car set are connected with a signal amplifying device. The utility model is compared with the traditional car logistics transmission system due to the increase of the signal amplifying device makes the signal acquisition and processing capacity has been greatly improved, to solve the original system controller for signal acquisition unit and the extensive processing function of a simple question. The communication of this system is stable, the communication will not appear interrupted, the car body control is perfect, the independence is strong, and the signal collection, parameter monitoring and setting is also very simple and convenient.

技术介绍
自行小车是在物流输送系统上比较常见的一种设备。它是通过车体上安装的集电器和装在轨道内的滑触线在移动接触中进行取电,提供给移动的小车,这种取电方式已经是很成熟的技术。但通过滑触线和集电器在滑动接触过程中进行通讯的方式却是一个比较特殊和困难的课题,因为通讯线路的滑触线和供电线路的滑触线都在同一根轨道内平行敷设,并且距离很近,之间仅有绝缘,线体裸露且没有屏蔽防护,而且滑触线和集电器滑动接触时存在很大阻抗(相对常规通讯方式),滑动过程中接触效果不稳定等因素,使得其通讯的成功率和可靠性很难保证。传统自行小车产品是通过车体上安装的集电器(又称电刷)和装在轨道上的滑触线滑动接触进行取电。地面控制柜内设有主控PLC,小车上一般也装有PLC和变频器,主控PLC通过滑触线传送的是继电控制信号,来控制小车执行相应的工艺动作。但是由于轨道和滑触线的尺寸、安装的要求及经济指标等各方面因素的局限性,使得轨道上的滑触线在数量上有限,通常装有八根滑触线,三根工业电源线、一根地线、三根控制信号线和一根占位信号线。其中三根控制信号线传输的是一种继电器式的 ...
