具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行 清楚；完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例，基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-3，一种用于汽车装载运输计数的自动控制系统，包括PLC输入单元1和PLC输出单元2，PLC输入单元1由数显计数器11和激光对射光电开关电源12组成；其中，数显计数器11用于车数计量显示，并保存计量结果；激光对射光电开关电源12用于为激光对射光电开关A及激光对射光电开关B提供工作电源。
PLC输出单元2由CPU芯片21、料仓口外绿灯HL1、料仓口外红灯HL2、料仓口内绿灯HL3、激光对射光电开关A和激光对射光电开关B组成；其中，CPU芯片21用于控制电气元件的工作状态，并通过设定的程序对输入的信号循环扫描；料仓口外绿灯HL1用于提示车辆准许进入料仓，料仓口外红灯HL2用于提示车辆禁止进入料仓，料仓口内绿灯HL3用于提示车辆进入料仓的位置正确；激光对射光电开关A用于里侧车厢尾位置检测，激光对射光电开关B用于外侧车厢头位置检测。
数显计数器11的电源输入端连接火线L与零线N，数显计数器11的信号输入端连接继电器KA，继电器KA的电源输入端连接火线L与零线N，激光对射光电开关电源12的电源输入端连接火线L与零线N。
CPU芯片21的Q0.0脚连接料仓口外绿灯HL1，CPU芯片21的Q0.1脚连接料仓口外红灯HL2，CPU芯片21的Q0.2脚连接料仓口内绿灯HL3，CPU芯片21的Q0.3脚连接继电器KA，激光对射光电开关A连接CPU芯片21的I0.0脚、L+脚，激光对射光电开关B连接CPU芯片21的I0.1脚、L+脚。
系统原理：当CPU芯片21上电时，则料仓口外绿灯HL1亮，车辆准入；倒车进入时，车辆厢体阻断激光对射光电开关B动作，料仓口外红灯HL2亮，料仓口外绿灯HL1灭，禁止其他车辆进入。
当车辆倒入漏斗下方位置时，激光对射光电开关A动作，此时料仓口内绿灯HL3亮，提示司机车辆位置正确，等待装车；其中，司机配合漏斗装载满车，需要稍作来回移动，通过激光对射光电开关A及激光对射光电开关B的逻辑控制，避免误触发导致计数错误。
车辆装载完毕驶出料仓时，CPU芯片21控制继电器KA输出信号给数显计数器11，同时料仓口外红灯HL2灭，料仓口外绿灯HL1亮，下一车辆可依次进行装载运输作业。
本用于汽车装载运输计数的自动控制系统，为区分开装载车与其他车辆，避免错误计数，可先测量好尾砂汽车运输车辆车厢高度和长度，以规避开铲运机等车辆；通过测量的结果，该车型车厢长度在8.2米～8.7米之间，高度为3米，故可将激光对射光电开关A与激光对射光电开关B安装在离地高2.8米、间距7米，并处于水平位置处。
本用于汽车装载运输计数的自动控制系统，通过将室外防水型的激光对射光电开关A和激光对射光电开关B安装在装载位，并现场采集进出的车辆信号给CPU芯片21循环扫描后，经继电器KA输出开关信号，由电子式数显计数器11显示车数计量，并保存计量结果；因此，通过本系统实现自动控制方式进行车数计量，具有计数准确、稳定、可靠性高的优点，并且极大的减少了人力成本。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
