How can intelligent electronic scales automatically recognize employee codes and store product names?

Implementing automatic binding and recording of employee codes and product names is equivalent to equipping each weighing data with "double insurance" - it can clarify responsibility attribution and make material flow traceable throughout the process. This is a "must-have function" in the MES/ERP system integration of the factory. Based on my hardware solutions and industry cases, I will break down four closed-loop implementation solutions for you.

Suzhou Yujingheng brand YJH-GS ，YJH-T7， YJH-A7 ，YJH-B7 ，YJH-T， YJH-A ，YJH-B， YJH-AI，YJH-DWS Recommended Industrial Electronic Scale Series

Four core solutions for automatically binding employee codes and product names

1. IC card/RFID dual-mode recognition

Principle: Employees swipe their card (employee ID)+scan the product code (product name), and the system automatically associates the two data chains to form a four-dimensional record of "employee ID - product name - weight - time".

Hardware configuration:

The electronic scale is equipped with an RFID card reader (supporting 10cm non-contact card swiping) and a two-dimensional scanning engine (capable of scanning product barcodes/QR codes)

Recommended model: Yujingheng YJH-A7 (supports ISO 14443 Type A/B cards, compatible with M1/CPU cards)

How can intelligent electronic scales automatically recognize employee codes and store product names?

Operation process:

A [Employee swiping IC card] -->B [System verification ID: OP001 Zhang San]

B -->C [Scan product barcode: 002 Fuji apple]

C -->D [System retrieves product name parameters: unit price 8.99 yuan/kg]

D -->E [Weighing the product: 2.5kg]

E -->F [Automatic storage: OP001+002+2.5kg+10:30:22]

Advantage:

Two factor authentication (work card+product code), eliminating loopholes such as "proxy weighing" and "wrong product name"

Support offline storage of 100000 records, data will not be lost after network disconnection

2. AI visual recognition+employee facial recognition (contactless solution)

Innovation point: The camera automatically captures the employee's face (employee ID) and product image (product name), without the need to touch the device throughout the entire process.

Applicable scenarios: Medical cleanrooms, sterile food areas (to avoid card contamination)

Core functions:

The facial database supports 500 people to input, with a recognition speed of ≤ 0.3 seconds and an error rate of<0.001%

AI product name recognition covers 2000+SKUs (fresh/industrial parts/reagents), and only 3 sample images need to be taken for training to add new product names

Case: Yuanmang Digital AI Recognition Scale is applied in supermarkets to achieve "recognizing product names when placing products+binding employees when brushing their faces"

3. ERP/MES system pre validation (digital factory solution)

Principle: Through API interface and linkage with enterprise management system, employee ID and product name are automatically synchronized from ERP work order to electronic scale.

Data flow direction:

ERP system (work order data) → electronic scale (pre loaded work number/product name) → weighing and returning to ERP (including weighing records of work number and product name)

Key configuration:

The electronic scale needs to support Modbus TCP/OPC UA protocol (such as Suzhou Yujingheng YJH-T7 YJH-T)

Employee ID automatically logs in through the factory LAN without the need for repeated input

Value:

Ensure strong correlation between weighing data and production work orders to avoid confusion (such as material from work order A being mistakenly recorded in work order B)

Support the generation of ERP reports based on both job number and product name dimensions, which can be directly used for cost accounting

4. Scan code binding for mobile APP (mobile job scenario)

Solution: Employees use the enterprise WeChat/dedicated APP to scan the QR code of the electronic scale (to obtain the device ID), enter their work ID, scan the product code, and upload the weighing data in real-time to the cloud.

Applicable scenarios: logistics couriers, warehouse mobile inventory clerks

Tool support:

The electronic scale is equipped with a 4G communication module (such as Suzhou Yujingheng YJH-T7 YJH-T), which supports real-time data synchronization to cloud servers

The APP can view "My Weighing Records" and support offline caching (automatically uploaded after network recovery)

The entire process of data storage and traceability

1. Dual backup mechanism of local and cloud

Local storage: The electronic scale has a built-in 32GB storage space, classified by the "job number date" folder, and supports exporting Excel/CSV files from a USB drive

Job number, product name code, product name, weight (kg), time, equipment number

OP001, 002, Fuji Apple, 2.52025-12-18 10:30:22, A03-001

Cloud storage: Synchronized to the enterprise's private cloud through MQTT protocol, supporting retrieval of historical data by job number/product name (such as "querying all 002 product name records of OP001 weighing last week")

2. Abnormal error prevention design

Warning for unbound work ID: When weighing directly without swiping the card, the electronic scale will lock and voice prompt "Please log in to work ID first"

Product name duplicate entry interception: Within 10 seconds, if the same product is scanned repeatedly, the system will prompt "Do you want to overwrite the previous record

Data encryption transmission: Employee IDs are stored using MD5 encryption to prevent sensitive information leakage
