Intelligent attendance checking and punching-in system

Abstract

The invention discloses an intelligent attendance checking and punching-in system. The intelligent attendance checking and punching-in system comprises an attendance checking terminal, a central processing unit and a control terminal, wherein the attendance checking terminal comprises an information acquisition module, an information storage module, a signal output module and a communication module and is used for acquiring attendance checking information and transmitting the information to the central processing unit; the information acquisition module comprises a sound wave acquisition module and a fingerprint acquisition module; the sound wave acquisition module is used for acquiring sound wave signals; the fingerprint acquisition module is used for acquiring attendance checking fingerprint information; the central processing unit is used for carrying out transformation processing on the information obtained by the attendance checking terminal, identifying user information and recording identification information and punching-in information of a user. The intelligent attendance checking and punching-in system disclosed by the invention can be used for effectively providing attendance checking and punching-in information of workers and preventing salary loss caused by the fact that the punching-in of the workers is invalid; the intelligent attendance checking and punching-in system can also be used for preventing phenomena that the punching-in of the workers is missed and the workers forget punching in and has relatively good application value and prospect.

Description

technical field [0001] The present invention relates to the technical field of information technology, in particular to an intelligent attendance checking system. Background technique [0002] Existing attendance check-in system includes microprocessor, attendance card reader, card writer, keyboard and memory, and can be equipped with display and printing device. The card reader reads the identification information on the attendance card and automatically generates a Information and / or user identification information and punch-in time record information, and can automatically judge the attendance status according to the preset attendance time, store it in the memory, and can also automatically print and / or display according to the set program or input it manually When manufacturing the time card, input user information and card writing instructions to the microprocessor through the keyboard, and the microprocessor automatically generates user identification information and w...

Problems solved by technology

The defect of this technology one is to need the specially-made time attendance card, has increased the quantity of the card that the user carries, causes unnecessary trouble to the user, the 2nd, increases the cost of making the card, the 3rd, in some occasions with access control device, Users not only need to punch the card for attendance, but also need to swipe the card to enter the door, which is cumbersome to operate

[0003] Today's employee attendance management and assessment system has gradually evolved from the traditional fixed punch card to the use of smart mobile phones or handheld computers, so that employee attendance management and assessment are no longer limited to fixed places. However, there are still many technologies in the existing technology. For example, the operating cost is relatively high, and the attendance recording equipment is usually set at a fixed location; the employee's attendance behavior may not be recognized by the attendance equipment; the attendance digital data cannot be provided in real time; Unable to meet the needs of enterprise organizations for mobile attendance management and assessment
