The magnetic cards, IC cards, and radio frequency cards widely used in the market cannot solve the problem of alternative punch-in. However, biometric technologies such as fingerprints cannot meet the problems of coal mines due to insufficient recognition accuracy, easy damage to fingerprints, unclear fingerprints, and difficulties in equipment maintenance. Need for safety attendance in underground mines. Hefei Longji Software Technology Co., Ltd., in view of the status quo of coal mine attendance and safety production, combined with the Institute of Automation of the Chinese Academy of Sciences, adopted the world’s most advanced iris recognition technology, and integrated iris recognition technology, computer network, application management software and other technologies. Through one-to-one eye iris registration and identification, attendance registration and real-time safety monitoring of personnel entering the mine, real-time statistics and counts of the number of people underground, thus completely plugging the traditional coal mine attendance management loopholes, reducing human factors, and improving the modern management level of the mine. A revolution in safety attendance.

The system is mainly composed of four parts: iris registration machine, iris recognition machine, server and attendance software.
Iris attendance registration machine: The registration unit is connected to the system through the network to complete the entry of basic personnel information, iris information entry, and verification.
Iris Time Attendance Recognition Machine: The recognition unit is connected to the system through the network to complete the identification of personnel based on the iris, and can give voice prompts according to the situation.
Server: Including iris data server, attendance server, log server, data backup server, mainly completes the storage and backup of personnel’s attendance data.
Safety attendance monitoring software: Mainly used for attendance assessment, management and safety supervision of underground coal mine workers. It can count and count the number of employees underground in real time; realize attendance data management, query, display, statistics, printing, modification, deletion, input and other functions, The management personnel can browse and query the situation of the underground personnel through the local area network.
Features of iris attendance recognition system
1. The iris recognition technology is free of contact, cannot be tampered with, and has high security.
2. Easy to use, it can be recognized at a glance, and the recognition speed is fast, the speed is about 1 second.
3. The statistics of attendance data are quick and no manual statistics are required.
4. The product is advanced. The iris identification technology is currently the most secure and unique human biometric technology among all biometrics.
5. Reliable product: It is very convenient and reliable to use, investment in one step, simple operation and long service life.
Main performance parameters of iris attendance machine
Recognition distance: 24-32cm
Iris recognition time: no more than 1 second
Maximum number of users: unlimited
Misrecognition rate: not more than 1:1.2 million. The false recognition rate is also called the false acceptance rate or false match rate, which indicates the degree to which unauthorized persons (impersonators) are confirmed as authorized persons (valid individuals).
Rejection rate: not more than 0.2%. Rejection rate is also called false rejection rate or false mismatch rate, which indicates the degree to which authorized persons (legitimate users) are not accurately recognized (misunderstood as imposters).
Temperature: 0-40 degrees Celsius
Humidity: <90%, no condensation
The underground iris attendance machine is of explosion-proof MA type.
Mine safety monitoring and attendance management software
Coal mine safety monitoring and attendance software is mainly used for the attendance assessment, management and safety supervision of underground coal mine employees. It can count and count the number of employees downhole in real time, and can query the time of employees getting in and out of the well in real time and the time of each employee downhole. According to each Workers can set the downhole time, and the advance attendance attendance in the well is invalid and recorded, and the downhole overtime system is prompted to achieve seamless attendance on the ground, integrated management, and eliminate potential safety hazards. It can realize attendance data management, query, display, statistics, print, modify, delete, input and other functions. Managers can browse through the local area network to query the status of the underground personnel. Provide management of multiple shifts and schedules, especially support the particularly complex shift system and shift arrangements of coal mining group companies; provide management of employees’ leave, overtime, and tolerance; provide data import and read interfaces for different attendance machines; And realize the statistics, summary and output of attendance daily, monthly, and annual attendance results into various reports; the attendance results are linked with the salary system and calculated.
Function introduction
Scheduling management: adapt to the very complex scheduling management of the coal mine industry. It can perform scheduling management in accordance with various scheduling methods such as normal work on the coal surface or underground shifts, and provide automatic scheduling (without scheduling) and graphical scheduling , Calendar scheduling, automatic shift and other scheduling methods, greatly simplifying the workload of scheduling;
Vacation management: realize the processing of various vacation methods such as employees working overtime, business trips, and asking for leave;
Attendance result processing: the calculation, summary, and exception handling of attendance results can be realized by day, month, year, etc.; daily attendance results: calculation and analysis of employees’ monthly attendance attendance; monthly attendance results: calculation of employees’ monthly attendance summary and analysis ；
Leadership query: It is convenient for leaders to summarize, query and analyze the attendance status of employees when they go down the well;
Attendance report: It can perform statistical analysis on the underground attendance data by department and time to assist safe production.
