Clock module, Keysheet module are connected with single chip control module, and the single chip control module is also connected with wireless module, fingerprint
Module.
In all modules of above-mentioned host and slave, single chip control module is the core of entire attendance recorder, display module
For showing time, personal information and attendance step suggestion content etc., clock module is used for time management, when generating real-time
Between, Keysheet module for personnel operate and information input, fingerprint module for personnel's finger print information acquisition with compare, wireless mould
Block is for the information transmission between host and slave, slave and slave.By the co-ordination of above-mentioned modules, this is wireless finger
Line attendance recorder can realize the wireless attendance in multiple terminals, not only avoided cumbersome wiring but also improved attendance efficiency, therefore the utility model has
Have the characteristics that at low cost, easy to use.
The fingerprint module is connected by serial ports with single chip control module, on fingerprint module and single chip control module
It is equipped with data line interface, as an improvement, selected interface is Micro USB interface, is plugged at any time after being arranged in this way.
The wireless module is connected by serial ports with single chip control module, for different from fingerprint module and single-chip microcontroller control
The connection type of molding block, selected interface are USB interface, had not only facilitated plug at any time after being arranged in this way but also avoidable connection is wrong
Accidentally.
The power module includes that 220V turns 5V and 5V turns 3.3V transforming circuit, and after being arranged in this way, i.e., available alternating current is examines
Diligent machine is powered, and battery or charge power supply can be used to be powered attendance recorder, even if in no alternating current or commercial power interruption
In the case where attendance recorder can all work normally, therefore the utility model versatility is stronger.
The wireless module is that (WiFi technology is big with coverage area, transmission speed is fast, high reliablity, biography for WiFi module
The features such as defeated distance is remote), it can increase host and slave after being arranged in this way, the data transmission distance between slave and slave, and
And cumbersome wiring is avoided, so that the flexibility of the utility model is more preferable, cost is lower, checking-in result is more effective.
Compared with prior art, the utility model has the following beneficial effects:
The utility model can unit/terminal work again can multiple terminals work, in the case where personnel are less arrange an attendance
Machine (unit/terminal) can complete attendance work, avoid the wasting of resources；It can be arranged in the case where personnel are more two or more
Attendance recorder (multiple terminals) completes attendance work, and the time is avoided to waste；The checking-in result of all slaves can carry out on host
It checks, does not need to check one by one, it is convenient and efficient.It is communicated, is kept away using WiFi technology between host and slave, slave and slave
Exempt from cumbersome wiring, reduce cost, extends data transmission distance, improve the validity of checking-in result；Attendance electromechanical source both can be used
5V battery or charge power supply power supply can be used in 220V alternating current again, expands the use scope of attendance recorder, improves the spirit of attendance recorder work
Activity and mobility.
