Design and Implementation of Electronic process Panel in Manufacturing Enterprises

Design and Implementation of Electronic process Panel in Manufacturing Enterprises
Preface
In the traditional production line process, the process is designed by means of equipment tools and posted to the specific Assembly positions after the specific review process. In this way, it is competent to assemble a single and slightly changed assembly line. However, in some cases. We have to face the following problems:
1. There are many products assembled in the production line. 2. Paper needs to be replaced frequently;
3. the model of the production line assembly is the same as 4. frequent replacement within a period of time, 5. as a result, a large number of sheets are posted. workers assemble and search for assembly drawings at the beginning of assembly. may cause No 8. necessary delays and losses;
9. The production line needs to be reviewed frequently when assembling new models. Process resumption 10. Miscellaneous 11. And the current resources of the enterprise are not fully utilized;
12. Numerous papers, 13. chaotic management;

In view of the above circumstances, we need a reasonable management of the production process and can get rid of the series of drawbacks brought about by the original paper processing process. To this end, a computer process flow management system is proposed. This system can be used to form a paperless office by means of modern process flows that are more scientific, convenient, and easier to manage.

Overall process

SYSTEM INTRODUCTION
The system contains three parts
Information Display of process stations: Information Display of each process station is mainly used to display and process information from the Management host.
Manage Host Control: Send the designed and reviewed process drawings to each process end as required
Internal information management: Responsible for the design process and review process. Send the design and approved process drawings to the management host. Switch and handle operations

System software and hardware design
Process Station Information Display Processing
In terms of hardware, the bottom-end features are simple and there are only a few tasks, mainly because of the bottom-end review of the process drawings and the process of resizing and so on. Therefore, a large display screen and a low-configuration control panel are adopted. The system is implemented in Linux after the reduction. The basic configuration is as follows:
The motherboard uses a 3.5-inch Single Board, 128 m cf card for memory, and a 12.1 LCD screen. Because the number of keyboard keys is small. Therefore, the self-made thin-film keyboard is directly connected to the keyboard control processing board and the PS/2 interface of the motherboard.
The system uses a Linux operating system that has been reduced and re-compiled, and uses the GTK + graphics library and the directfb Based on the framebuffer graphics engine to directly output graphics on framebuffer. The display speed is very fast due to the implementation of graphics in the kernel, and the Linux network performance is added to achieve the display of the process end. The interface is shown as follows:

For Linux cutting and GTK + graphics library and graphics engine directfb usage, you can refer to the relevant books and materials and will not describe them here.

Manage host control terminal Processing
Use a high-performance Dell commercial PC, and the platform uses the Win XP system. The software is implemented through Delphi programming, because the display methods of various manufacturers and various processes are different and similar. Therefore, when designing a process, we also need to consider reapplying a similar process model. Therefore, it is particularly important to develop a design template. With this template, you can easily design and save various types of processes as templates, so that you can call them up during design. In this way, you can directly open the application when using a similar template.

Because the information display end of the Process station involves operations such as amplification and reduction, you can easily save the process map as a BMP file after it is involved.

When the design is completed and saved, the system automatically determines whether the information display end of the specified process station is connected to the system. If the information display end of the Process station is connected, the file is automatically transferred to the Information Display end of the Process station, it is also stored in the local directory. If there is no connection, it is automatically recorded in the log and saved locally. Update or add the process diagram immediately after the process station information shows the end connection.

Handling of enterprise internal information management
Establish a network topology within an enterprise through the enterprise's internal OA

In this way, through the department-level computer through the OA system, the design process Department drawings are reviewed and issued to the management Host Control. This ensures that the management Host Control Internal drawings are reviewed. You only need to pass the review at the Information Display end of the Process station. When the information displayed at the process station is approved, the information is automatically transferred to the management host for record filing. At the same time, the information is also returned to the department-level database server. If the review fails, the system will return to the management host and report the information to the Department ..... In this way, layer-by-layer management is adopted. Form a management chain. To achieve paperless office. At the same time, it can be expanded on this basis to connect the control machines in the production workshop to form a set of systems, so that various systems can work collaboratively.

Summary
The system is built on different platforms and languages based on the current integrated enterprise work mode. In this way, the information display end of the Process station is implemented in a low-configuration embedded Linux mode. The system is systematically integrated with the enterprise intranet office on other terminals, which greatly reduces the cost and integrates the internal system of the enterprise. So that the production and manufacturing enterprises only need to spend a small investment to replace the original paper-based process design. At the same time, they can also expand on this basis (such as on-site production information interaction ), to implement more complex functions.

This article puts forward a new point of view:
Among many manufacturing enterprises, more are paper-based process processing. In this paper, the processing method of electronic process Panel is proposed, which is oriented to embedded devices in the Linux operating system. At the same time, it also integrates the enterprise office automation system. Practice has proved that this method is cost-effective and easy to expand. It is convenient and practical to run in a manufacturing company. This removes the hassle of complex paper and tedious review. Become clear!
