overview
The previous article introduced the plan management function of the Odoo MES system in the world's No. 1 open source and free Odoo enterprise information management system. This article explains the production execution function of the Odoo MES system. The specific implementation process is as follows:
Tablets are deployed on-site in the workshop, and workshop personnel log in to the MES system from the tablet. Click on the process order issued by the workshop dispatcher on the tablet to start the process production.
The tablet computer is connected to the equipment required for process operation through the IoT Box, such as camera equipment, code scanning gun, label printer, or processing machine tools, quality inspection and other equipment.
The operator completes the process production, directly operates the process sheet on the tablet, and records the production site data. For example, fill in the actual consumption quantity of materials, scan codes to fill in material batches, click the "photograph" button to collect on-site photos, click the "print" button to print product labels, and so on.
Working hour record: After the process production is started in MES, the process order will automatically start timing. During the production process, the production can be suspended/continued. If there are some reasons, such as lack of material, the operation order can be blocked (set aside to suspend production).
For problems on the production site, such as drawing errors and equipment failures, you can initiate an on-site problem feedback form with one click from the process sheet.
device connection
The MES system is connected to the production equipment through the Internet of Things Box (IoT Box). Taking on-site photo collection as an example, on the MES process sheet on the tablet computer, click the "photograph" button, the MES system will send the photo command to the IoT Box, and the IoT Box will convert the command into a driving command for the camera device, and drive the device to take pictures. The photo is sent back to the IoT Box, and the IoT Box is sent back to the MES system, and the photo is displayed on the MES process order.
The IoT Box has its own drivers for common devices, such as the drivers for printing devices, USB devices, and serial devices, and the IoT Box has its own drivers. For other industrial devices, such as devices with communication protocols such as Modbus and OPC, you can purchase or develop corresponding device drivers to run on the IoT Box to control device actions and collect device data.
The IoT Box can drive the AGV to work. For example, one-key calls the AGV to transport the materials required for the production process, and one-key calls the AGV to ferry the workpiece between the previous and subsequent processes.
data collection
The process sheet displayed on the tablet computer at the production site has multiple steps, among which the "material registration" step can fill in the quantity of material consumed and the batch/serial number of the material. The batch/serial number can be filled in by hand or scanned.
Automatic recording of working hours
生产现场工序单启动生产后，系统自动开启计时。生产过程中，可以暂停，如中午休息时段可以暂停计时。工序单完工，自动记录实际生产工时，也可以手工录入或修改生产工时。
异常反馈
现场生产中，可以随时反馈问题。现场问题有两种，一种是设备故障，可以一键发起设备维修/保养请求单。一种是质量问题，如图纸错误，物料缺陷等，一键发起质量警报单，如下图所示。
可以自定义现场问题单处理流程，如下图所示流程，新建问题单-->车间主管确认-->设计确认-->物资主管确认-->关闭。
现场问题单的处理过程，车间现场发起问题描述，问题描述也可以拍照说明。如下图所示，问题处理人员填写“纠正动作”，即问题的处理方法，或处理过程。管理人员，或质控人员，填写“预防动作”，即为了避免再次发生类似问题，应该采取的一些预防措施。
