　　RFID smart factory personnel management system solution

　　1 . System background

　　Manufacturing enterprises are often personnel-intensive enterprises, and the management of enterprises is often more complicated. In such enterprises, management is mostly through systems, and the most important point in system management is: Are there loopholes? Is the implementation in place? If not, good management results will not be achieved. Any point of disconnection or problems 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 with management methods has always been what manufacturing enterprises have been looking for. Like 5S management, 6S management, Six Sigma management, etc., they are born in response to demand.

　　According to the actual needs of the factory, this system adopts the most advanced RFID technology (radio frequency technology) combined with factory management to realize intelligent control of the attendance management of factory personnel and work area positioning management, so as to make the management of the factory more efficient and effective. intelligent.

　　2 . introduction

　　Workers enter the factory with an electronic tag card every day, because the electronic tag is active and can continuously transmit information. When the worker reaches the reading area, the card reader installed in the reading area will read the tag Information, the card reader transmits the signal to the computer through the network cable or serial port, etc., and the detailed information of the worker can be seen by comparing the database. Each reader in the read-write area can be set to view at a fixed time interval. In other places of the factory: place readers in houses, roads, canteens, etc. When there are behaviors such as signal disappearance and cross-regional behavior, the central control room audible and visual alarm prompts, and the management personnel are dealing with it.

　　3. System functions

　　3.1 Worker Attendance Management System

　　Workers wear electronic tag cards to and from get off work every day. The card is a more advanced radio frequency card with a built-in ZIGBEE wireless chip, which can communicate with a card reader at a distance of 0 to 80 meters.

　　Go to work: Workers wear an electronic card and arrive at the entrance of the factory. A card reader is installed at the entrance of the factory. When the employee card reaches the recognition range of the reader, the reader can receive the information from the employee card, and the reader can use the network cable or The serial line transmits the data to the management machine, and the management machine immediately verifies the personnel information, that is (**department, **workshop, **production line, basic employee information, etc.). If it is a factory employee, the system automatically records Attendance form to the factory on the day. If an employee arrives at the factory within the time period specified by the system, the system will record a late arrival alarm. On the one hand, the employee’s ID number will be recorded in the system [Factory Monthly Attendance Late and Early Leave Table], on the other hand, the [Employee Monthly Attendance] will be recalled in the database. Table], and record the late records of the day. Because the card uses a chip with a longer communication distance, personnel do not need to deliberately walk to the card reader, get off the car, or stop to swipe the card, and the reader can read 200 tags at the same time. Greatly improve the efficiency of entering the factory.

　　Off duty: Workers wear an electronic card and arrive at the entrance of the factory. A card reader is installed at the entrance of the factory. When the employee card reaches the recognition range of the reader, the reader can receive the information from the employee card, and the reader can use the network cable or The serial port line transmits the data to the management machine, and the system automatically records it to the factory attendance sheet of the day. If an employee leaves the factory in advance within the time period specified by the system, the system will record an early exit alarm. On the one hand, the employee’s ID number will be recorded in the system [Factory Monthly Attendance Late and Early Leave Form], and on the other hand, the [Employee Monthly Attendance List] will be recalled in the database. ], and record the early departure record of the day.

　　Overtime: When the factory production requires employees to work overtime, the workshop director can give feedback to the department responsible for attendance to modify or add or delete the system settings.

　　Leaving the factory under other circumstances: When an employee needs to leave the factory due to special circumstances, the workshop director or production line team leader must give feedback to the department responsible for attendance, and the manager can make notes on the system and mark the reason.

　　3.2 Worker workplace management system

　　3.2.1 Overview of the workplace

　　Each employee distributes an electronic tag, which 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 can be stored In the background database corresponding to this ID number, it is available for management personnel to query and access.

　　The interior of the factory is divided into administrative office buildings and production workshop areas. Active card readers are installed at the entrances of the two working areas to read tag information.

　　Because the employee tags are active, they are sending signals all the time. When each employee with a tag enters his work area, the reader reads the tag content.

　　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; 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.

　　3.2.2 Workshop procedure authority (this function is optional)

　　In the factory workshop area, each production line is divided into different production processes, for example, production line 1 is divided into: process A, process B, ..., process X, etc. Similarly, install a fixed card reader at the entrance of each process workshop to set the entry authority of the employees. For example, employees in the process A workshop are not allowed to enter the process B workshop without authorization.

　　When an employee enters, the card reader reads the employee card information and sends it to the management machine to query the employee’s information and compare them. If the information matches, the employee can pass smoothly; if the information read by the card reader does not match, the same When an alarm occurs, it will prompt illegal entry, and the relevant management personnel will be reminded to deal with it.

　　A fixed card reader is installed in each process. Before each process, the person in charge of the process will first swipe his electronic label card on the fixed card reader, and then put the label on the product on the reader Swipe, the card reader obtains the relevant information of the employee card and product label respectively;

　　After entering a certain process, the worker executes the process. When the task is completed, the person in charge of the process reads the product label on the card reader, indicating that the process has been completed, and records the time to complete the process;

　　At the beginning and end of each process, the person in charge of the process first swipes his IC card on the reader of each station, and then swipes the electronic label on the product on the reader to indicate the product The process is completed by the person in charge corresponding to the IC card, and the responsibilities are clearly defined;

　　Start timing when the process is started, and end when the process ends, and record the time used in the process, so that the number of finished products can be counted within a period of time, and output and display on the host computer server or electronic screen;

　　In the final inspection process of the product, it is detected where there is a problem, directly find the corresponding process, find the person in charge of the relevant process, and complete the rework; after the product is completed and passed the inspection, the label on the product is removed, Data is initialized for repeated use of electronic tags.

　　3. 2. 3 Employee location track record

　　Employee rough positioning track: It reads the employee's electronic tag card through the readers installed in different positions, and then judges the employee's current location; and can describe the employee's movement according to the different locations of the employee's entry and exit. traces of.

　　Employee precise positioning track: Perform regional positioning based on the strength of the card reader signal, set a certain signal coverage radius (such as 10 to 200 meters), and locate personnel entering and exiting within the radius area. The reader reads the employee tags at regular intervals according to the time set in the background of the system, and locates the area where each worker is active in the production workshop. According to the positioning interval, the real-time action trajectory of each employee is depicted.

　　The database can be set up in advance in the management system, and the detailed work information of each employee can be entered in the database: such as the employee ID number, employee name, type of work, the work area is the **factory area** group** production line, the name of the team leader, Wait for information.

　　When an employee wears a tag card and enters each factory area, the reader at the entrance of the factory door will read the employee card and compare the employee’s ID number with the information in the database. If the employee’s working area is indeed in the factory area, The system releases normally, and records and saves the specific time when employees enter the site. When the employee leaves the factory, the reader on the exit of the factory gate reads the employee card, and the system automatically records the specific time when the employee leaves the factory. If an employee goes out of the factory to the office area, the reader/writer in the office area will also record the employee's entry and exit records.

　　The system will automatically generate the action trajectory of each employee, and will list the number of employees in and out of each factory or office area, stay time, walking trajectory in the factory area, and so on.

　　and then judge the work efficiency of each employee. If it is a front-line production employee, according to his job responsibility is to produce in the factory area, then the number of times he leaves the factory area and the time spent in the factory area are the evaluation criteria for him; if it is a management staff, according to his job responsibility, he is working in the office area. , Or walking management, then the number of times of entry and exit and stay time in the factory and office area are the evaluation criteria for him.

　　If you want to check the action track of which employee, you can check it on the system management machine.

　　3. 3 Combination of employee tag card and work card

　　Electronic wallet: The employee tag card can integrate passive IC card functions. The card storage: employee’s basic information, stored value function, credit card consumption function, and can be designed according to the factory’s original card compatible.

　　Hardware coordination: There are two ways to combine the hardware of the employee tag card and the original worker card: 1. The original worker card can be built into the employee label card, that is, a passive 13.56MHZ card needs to be redesigned in the employee label card. Modification on the hardware requires customization.

　　2. Since the original card and the label card have the same size, they can be pasted on the label card with a strong adhesive, and the dual cards can also be used together.
