4WRTE 25 V350L-46/6EG24K31/A5M 无人值守称重系统工作流程

1.系统管理员将射频卡发给司机，上面已录入汽车车号等内容，司机可将卡片贴在汽车前挡风玻璃上。

2.车辆到离秤台几米远时，读卡器检测到车辆上的射频卡信息，通过智嵌物联串口服务器上传到后台，后台自动记录车辆信息。

3.后台系统在判定秤台上无车辆过磅时，向智嵌物联继电器控制器发送控制指令，控制进口栏杆机打开，让车辆通过，开上秤台； 

4.继电器控制器检测前后两个红外定位传感器，没有被遮挡，说明车辆停在地磅的称重有效区，继电器控制器向主动向后台上报状态。

5.车辆停稳后，后台系统向串口服务器发送读取地磅数据的指令，并将返回的重量值保存。

6.称重完毕，后台系统向继电器控制板发送控制指令，使出口栏杆机抬起，让汽车驶出秤台； 

7.在出口处，放置一台磅单打印机，后台向串口服务器发送打印榜单指令，司机撕下打印好的磅单后即可离开； 

1.2无人值守称重系统组成

1地磅

地磅的RS485接口接到串口服务器的RS485接口上，通过串口服务器将地磅的数据上传到后台系统。

2地感线圈

前一个地感线圈传感器主要检测汽车的尾部是否已经过了地感线圈传感器，确保汽车完全开上秤台。汽车开上秤台以后放下前一个栏杆机的栏杆；当汽车称重完以后过了后一个栏杆机的地感线圈传感器时，后一个栏杆机的栏杆自动放下，这时汽车已经完全驶出秤台。

3红外定位传感器

在磅体两端各安装一对红外定位传感器，当网络继电器控制器检测到红外线被车辆挡住时，后台系统禁止称重系统数据保存，称重流程终止。

4道闸（栏杆机）

秤台前后各一个栏杆机，控制车辆有序称重。栏杆机可通过智嵌物联的网络继电器控制板进行远程控制。

5电子标签

电子标签内存入有车辆的信息，具有唯一性，可通过称台旁的读卡器读出电子标签的车辆信息。

6读卡器

电子标签读卡器可读取电子标签的信息，并通过串口服务器将电子标签的信息上传到后台系统。

7摄像头

当汽车开上秤台时抓拍汽车的图像（主要是车牌号）存入电脑，同时可以进行录像。

8打印机
通过串口服务器控制打印机打印榜单。
