Hainan Shidian UWB helps a famous nutritional chemical enterprise to improve production management efficiency

I. Overview of the project background

A well-known multinational nutritional products enterprise in Jiangsu's production base factory is responsible for carrying the brand of nutritional products in the global sales volume of production tasks, due to the nutritional products of the production process of numerous procedures, production tasks and production line employees are huge, which gives the enterprise's operations and management department has brought the production process error correction, production efficiency, production of staff attendance in the management of the challenges and problems. Through our UWB positioning-based location data application development platform system can monitor the entire production process and employee action track, greatly improving the production and management efficiency of the enterprise.

II. Current management pain points

• Difficulty in personnel management, one person with multiple posts, often due to a shortage of personnel from other assembly processes to transfer people difficult to manage.
• Difficulty in controlling materials, complexity of production processes, full assembly line operation for insourcing and piecemeal operation for outsourcing.
• It is difficult to optimize production efficiency, and there is the phenomenon of personnel crosstalk, which is difficult to assess and control and affects production efficiency.
• No real-time data support management lag, production progress is not transparent according to the real-time production status to make further personnel adjustments

III. UWB-based solutions

In order to solve the above "neck" problem, enhance the production process of real-time monitoring of the process, found that the process errors can be timely alarm and error correction, while efficient management of production staff work efficiency during the work period, high-quality and efficient completion of urgent production tasks, the enterprise in one of their production workshop deployment of Hainan Shidian UWB positioning base stations At the same time in each raw material boxes; barrels, production staff are bound to the corresponding positioning tags, in the upper application platform through the production of task orders and UWB tag ID binding can be a full-process monitoring of the process and progress of the production order, and through the UWB with ink screen tags real-time display of the current process and the next process, to remind the field operation of the staff to prevent process errors, based on UWB process monitoring The logic diagram of UWB-based process monitoring is shown in Figure 1 below:

^{Fig. 1 Schematic diagram of production process monitoring logic based on UWB position data}

According to the area size of the production line workshop, a total of 50 UWB positioning base stations are installed and arranged in the monitoring area on the first and second floors, according to the CAD drawings given in the base station deployment location plan as shown in Figure 2 below:

^{Figure 2 UWB base station deployment scheme diagram}

UWB hardware positioning base stations and tags only provide basic location information data, in order to make use of these location data, but also less combined with the production process flow and business logic process judgment based on the data analysis and data display, so the open UWB hardware data reporting API interface is particularly important, only then the owners of the application side of the value of the positioning data can be harvested. The final UWB positioning hardware and platform application software docking application framework is shown in Figure 3 below:

The final system application framework diagram is shown in Figure 4 below:

IV. Upper platform application demonstration

1) Staff time statistics - business functions, you can count the staff on duty hours, attendance records query, designated area staff attendance query, generate staff attendance statistics such as leaving work, overtime; violation of the information, as shown in Figure 5 below:

^{Figure 5 Employee Management Attendance Application Platform Interface}

2) Material flow tracking-business functions, logistics flow statistics for each process, record the length of production logistics into each process, displayed in the form of a report to support the export of material flow time statistics for each process (Excel form), as shown in Figure 6 below:

^{Figure 6 Material flow tracking application platform interface}

3) Material visualization monitoring - business functions, real-time display of material location information on the map, quickly search for the location of the specified material information, intuitive understanding of the entire process of material flow and production line efficiency analysis and other data, as shown in Figure VII below:

V. Summary of project applications

In the era of industrial digitalization, the digital transformation of health is driven by value. For the well-known nutritional products enterprise, a set of 3D visualization positioning system based on UWB positioning technology, through the connection with the upper WMS system, to change the production data recorded manually, the production process errors are frequent, and the production staff is difficult to manage, and other difficult problems, based on the UWB basic positioning data and the business production logic process flow binding, release the real value behind the data, and improve the production and management efficiency, truly realize the enterprise operation and management cost reduction. management efficiency, truly realizing the enterprise operation and management of cost reduction and efficiency.
