(2) Realize the supervision of product circulation links, and realize the real-time data collection and traceability of each link.
(3) The data collected in the production process integrates the data interface with the enterprise ERP system, which facilitates office personnel or management personnel to understand the current situation of the workshop in time, and improves work efficiency.
Chapter 3 Function Introduction
3.1 Functional design
The barcode integration system is established with the ERP system production order barcode information. When the production picks up, the barcode scan or data collector collects the production order barcode, which can clarify the sales order, production product, production quantity, and production of the order in real time. Workshop, production and completion time, and required material information. During production picking, input or scan the production instruction barcode on the collector, and the barcode system will automatically generate the production picking list and associate the production order number and other information; the product barcode will be affixed during product completion inspection or packaging, and scanned during storage The package bar code, collect information directly or upload it to automatically generate an ERP system product warehousing list, and automatically associate the production order number, product code, name, quantity and other information.
3.1.1 Existing problems
a) The work efficiency is low, and the data cannot be reflected in the ERP in time
b) Raw material feeding error (receiving wrong material), resulting in unqualified products or waste of materials
c) How to control first-in first-out for picking
d) Low efficiency of warehouse inventory and inaccurate data
e) Unable to trace the batch number, production information, circulation information of products in progress, etc. of the product
f) Production schedule, material transfer, storage time and accuracy are difficult to reflect
g) Unable to prevent cross-stocking
3.1.2 Solution
With the aid of the barcode system, the effective management personnel, work orders, parts, semi-finished products, products, procedures and production process information can be scanned through barcodes to track and record the production process of the product, reduce errors caused by human input, and improve the integrity of production information Sex and safety.
3.2 Solution
This asset management system uses windows as the operating platform and SQLserver2005 as the system foundation. Each function is designed modularly, and each function module is scheduled, coordinated, and exchanged with a unified operation interface. The system software has the characteristics of friendly interface, easy operation and powerful functions.
3.2.1 User management and operation log function
The system saves all the product information that the company needs to produce. In order to ensure the security of asset information and prevent malicious destruction of asset data, the system has strengthened user authority control and system log management functions to record every step of all users in real time. .
3.2.2 Data backup function
Back up all the information and data in the system to prevent data loss caused by non-human factors or human factors. There are many backup methods, such as Excel mode, database file mode, etc. The operation method can be automatic or manual operation. .
3.2.3 Barcode generation and printing module
Barcode labels are used as product identification media on the production line, and the information in the labels can accurately identify and distinguish different types and batches of products. In the barcode generation interface, you only need to enter the product drawing number, product name, production batch, production date, customer code and other related information, and the system will automatically generate a unique product code based on the entered information. When detecting barcode information, only You need to scan and verify the barcode of the corresponding product.
3.2.4 Tag read and write control
The label information entered into the system is written into the label barcode, and the accuracy of the data in the label is verified by reading the data in the label barcode. In the entire generation process, the corresponding product barcode is scanned in each link, and only the direct barcode information is scanned in the welding link. The other links are mainly from the blanking, assembly, and finished products in and out of the warehouse. The sheet bar code information is mainly used. The whole reading and writing process is real-time It records the time period and link the product was inspected by which employee, paving the way for product traceability.
3.2.5 Terminal interactive function
On the production line, the handheld terminal scanning method is adopted, and the data collected from the products on the production line can be directly imported into the PC management system through WIFI or directly to realize the system data connection.
3.2.6 Traceability function
The information of each link of the product from production to delivery is recorded on the barcode label with a unique code. The operation time, location, and personnel of each link are recorded in detail, which ensures that all links of the entire product traceability system are recorded. The absence of loopholes satisfies the needs of enterprises for forward and reverse traceability, effectively protects processing enterprises against illegal and fraudulent operations, traces and monitors the entire circulation link, and guarantees products and product flow to prevent the occurrence of fleeing goods.
3.2.7 Inventory management
The barcode integration system is established with the ERP system purchase order material barcode information, which is provided to the supplier or self-posted. When the supplier material arrives, the material barcode can be scanned by the barcode gun or collected by the data collector, and the purchase order number, material code, detailed specifications, order quantity and delivery date of this batch of materials can be clarified in real time. Collect the information directly or upload it to automatically generate the ERP system outsourcing warehouse receipt, and retain the logical relationship of the purchase order.
3.2.8 Information entry, query, and modification functions
Before the material is put into production, the relevant information of the material needs to be entered into the management system, and then the entered information is printed on the bar code label, and the subsequent production process only needs to be scanned through the PDA terminal. This system has good information and data The input interface is simple to operate and easy to use. The query function can accurately search through the combination of conditions and also modify the relevant information (only for administrators).
3.2.9 Report statistics function
Report statistics can analyze the relevant data in the asset information, and make relevant intelligent analysis, such as: calculating the depreciation of the asset equipment to calculate the list of equipment that needs to be supplemented, the current use situation of the asset equipment and other types of intelligent data analysis Features.
