1. Program overview
Production enterprises are often personnel-intensive enterprises, and the management of enterprises is often more complicated. Most of these enterprises are managed through systems, and the most important point in system management is: Are there loopholes? Whether to implement In place? If not, good management results will not be achieved. Any disconnection or problem in the production link will cause disconnection or problems in the entire production chain, which will affect product quality and affect the company’s brand. So how to manage each point in the production chain? Achieve 100% execution? How to combine advanced management concepts and management methods has always been what production-oriented enterprises have been looking for.
This system is based on the actual needs of the factory, using the most advanced RFID technology (radio frequency technology), image processing technology, LED display technology, network communication technology and digital processing technology combined with factory management, for the attendance management of factory personnel, enter the work Regional management, etc. realize intelligent control, which in turn makes the management of the factory more efficient and intelligent.
2. System overview
Each employee distributes an electronic label badge, the label stores a unique ID number that can uniquely identify the employee, and can also store simple information about the employee: name, title, type of work, contact information, department, etc.; other more detailed information It can be stored in the back-end database corresponding to this ID number for management personnel to query and access.
Workers enter the workshop area of the production plant and install readers and antennas at the entrances and exits of the two work areas to read tag information.
When the card reader reads the information, it sends the data to the upper computer of the system through the communication interface, and compares it with the employee’s information in the upper computer: if the employee’s information matches the information in the back-end database, it can be entered smoothly; If it does not belong to this working area, that is, the information does not match, then the reader will give an alarm after reading this signal (the alarm method is: 1, on the interface of the management system, prompt 2, there is a management system that controls the on-site sound and light alarm Device). Tell the management staff that the employee does not belong to this work area and is illegal entry, and corresponding measures can be taken.
Set the number of people entering each production workshop area in the background. If the authorized personnel are full, when someone enters the production workshop, the card reader reads the employee’s information and alarms, indicating that the number of employees has been exceeded, and the LED real screen sound and light alarms.
3. Technical solution
1. Function overview
Implement unified and standardized management of the personnel involved in the system to realize the digitization and informatization of the information of the identified objects and the standardization and systematization of the overall process:
1. Real-time management, quick and easy operation, detailed log record, complete “management link”;
2. Automatic identification, long distance, high precision, good anti-interference, strong environmental adaptability, and realize “intelligent judgment”;
3. Information is disclosed by level, with strict authority control and clear levels, to achieve “upward responsibility”;
4. The system data and the system hardware fingerprint are bound and encrypted, and the module data is encrypted and transmitted;
5. The system is independently encrypted and coded to prevent information leakage and facilitate data fusion;
6. A strong supervisory and supervisory role requires personnel to consciously abide by system rules and operating procedures, which facilitates real-time control, inspection and supervision by leaders;
7. Humanized management, avoid conflicts, unique early warning and alarm functions;
8. Unique quantitative management of safety credit value and quantitative work statistics, which is convenient for quantitative assessment;
9. Distributed structure, convenient for networking, mobile deployment and scope expansion;
10. Modular design, convenient for function expansion and special module customization
2. Processing flow
Data collection layer: This layer is directly connected with each RFID card reader to collect the data returned by the card reader. All data interactions with the card reader are filtered by this layer before being passed to the database layer, which can reduce the redundant data of the database and reduce the burden on the management application layer.
Database layer: SQL SERVER database system is adopted, which can accurately save large-capacity data in real time. Set up data security and backup mechanisms at the same time.
Management application layer: This layer is the main application presentation layer of the system, and all functions that directly interact with management users are distributed in this layer. Including system management, RFID tag management, personnel management, plant area query, alarm reminder, query statistics, etc.
4. System advantages
(1) Install RFID readers, antennas and other equipment concealedly through customized stainless steel boxes;
(2) All products are independently developed by the company to ensure the convenience of later maintenance and interface customization;
(3) Multiple clients collect data, receive and process data in real time;
(4) The data situation of the personnel in the factory can be dynamically monitored.
(5) Unauthorized persons or persons who forgot to carry RFID badges shall report to the police and take pictures.
Fourth, the implementation of the program
1. System equipment
(1) RFID reader
Function: read RFID tag data;
(2) RFID antenna
(3) RFID middleware data processing
According to your organization’s network and environment status requirements, you can customize local storage data, or upload it to the database center after processing.
(4) Invisible box
Used to hide RFID card readers, RFID antennas and other equipment, etc.
(5) RFID employee badge
It can be carried on the human body and can be customized in various sizes according to customer requirements.
(6) Various auxiliary materials and cables
(7) The desktop card issuer is used to initialize the data of the personnel tag.
(8) The LED display screen is used to display the number of employees working in the work area.
