Embodiment
Structure of the present utility model is as shown in Figure 1 and Figure 2: the output unit 2 that comprises power supply 1, control module and be connected with control module (being the PC interface), also include identification unit 3 (being the fingerprint identification device of selling on the market) and a wireless transmission unit 4 of being connected with control module, can link to each other with INTERNET internet 5 by this wireless transmission unit 4.The keyboard display unit 8 that control module comprises the clock reference unit 6 be made up of clock chip DS12887 and its accessory circuit, CPU CPU (central processing unit) 7, is made up of keyboard display chip BC7281,74HC164 and its peripheral circuits; storage and the power-down data protection unit 9 formed by storage chip 28C256, resistance R 1 and stabilivolt DW1, the speech play unit of forming by speech chip ZY1420 and accessory circuit thereof 10.On control module, be provided with the radio-frequency card unit of forming by chip MTP-K4 and accessory circuit thereof 11.
The utility model system principle: see Fig. 1
This device is by the fingerprint on site attendance record terminal, and public network IP server receiving end is formed.The two utilizes wireless network such as GPRS (GPRS (General Packet Radio Service)) communication modes swap data by mobile platform.
The fingerprint on site attendance recorder adopts advanced biological identification technology---fingerprint recognition, as the data acquisition sources of native system.Because intrinsic uniqueness, the non-reproduction of human fingerprint stopped replacement, allograph phenomenon in the work attendance incident.Attendance data is sent on the internet by wireless modem according to ICP/IP protocol packing back, thereby realizes information sharing.
For adapting to special industry, phenomenons such as the finger wear of the special population under the abominable working condition, permanent disability, the design has done to become privileged design aspect software and hardware, and increased radio-frequency card unit 11 as complementary work attendance use, thereby this equipment of making has possessed 1: N and 1: 1 two kinds of fingerprint recognition mode, improved recognition success rate and recognition speed greatly.
Circuit is formed: see Fig. 2
Master control borad is the control center of system in the circuit; main circuit comprises following part: CPU CPU (central processing unit) 7; non-volatile memory and power-down data protection unit 9; the radio-frequency card read module; keyboard display unit 8, clock reference unit 6, fingerprint head interface; the wireless modem interface, speech play unit 10 and power supply unit grade.
Power unit: the 220V civil power is through the laggard power input interface J1 that goes into master control borad of transformer; alternating current after the transformation is sent into rectifier bridge QL1 after F1 and over-voltage protector RV1, TV1 are insured in the recovery certainly of overcurrent protection; over-voltage protector RV2, TV2 are passed through in the output of rectifier bridge again, filtering after Switching Power Supply LM2575 output native system needed+operating voltage of 5V.
Keyboard display unit 8: keyboard shows that control is made of keyboard display chip BC7281,74HC164 and the accessory circuit around it, the interface and the charactron display interface of film input keyboard are provided, undertake the parameter setting of system, revising panel operations such as clock adjustment.Show the result that CPU handles in real time, improved the real-time of system monitoring.
The module interface of fingerprint identification device 3 (JP4): because human fingerprint has non-repeatability, for distinguishing the identity of different user, native system adopts current state-of-the-art biological identification technology one fingerprint recognition district user identity, the employing fingerprint identification technology has prevented to replace the generation of work attendance, has improved the accuracy of data.
The radio-frequency card unit is made up of U8 chip MTP-K4 and accessory circuit thereof: the management of strengthening system, improved the success ratio of work attendance.
Clock reference unit 6: clock reference is made up of clock chip DS12887 and its accessory circuit, and it is little that this clock chip has a clocking error, the function of inner band lithium electricity, leap year compensation and solution Y2K problem.
Storage and power-down data protection unit 9: the storage data are finished by storage chip 28C256, and power down protection is formed the sampled signal of power down protection by resistance R 1 and stabilivolt DW1, have prevented that accidental outage from just causing the generation in the loss of data of work attendance.
Speech play unit 10: formed voice playing circuit by speech chip ZY1420 and accessory circuit thereof, good man computer interface is provided.
With the terminal PC interface: attendance data can be downloaded on the enterprise office PC by this interface.
Wireless transmission interface (JP3): native system has adopted the wireless modem with ICP/IP protocol to carry out data transmission, on-the-spot attendance data is packaged into the ICP/IP protocol bag and is transmitted on the INTERNET by wireless modem, receive by the public network IP server, realize data sharing.
CPU CPU (central processing unit) 7: the CPU (central processing unit) of native system adopts AT89C52, CPU (central processing unit) detects keyboard data or order on the one hand, gather fingerprint, after treatment or drive charactron and show, or speech play, or data storage and wireless transmission, received RF card input data are gathered fingerprint on the one hand, and output shows, voice suggestion regularly sends data to server.
The utility model principle of work:
The summary of circuit working process: after the energising, CPU element is at first finished the initialization of peripherals and the self check work of important devices and unit.By after, system is in the work attendance state and shows real-time time information.At this moment, by directly by fingerprint on the fingerprint head (1: put fingerprint after the N mode) or earlier brushing radio-frequency card and finish the work attendance work of registering, by whether acousto-optic hint is all arranged to fingerprint head (1: 1 mode).
Also can enter System Management Mode (must import password) by swipe the card (control card) this moment, finishes a series of system management work or registration, deletion fingerprint to system.
System can upload to public network server with up-to-date attendance record automatically according to the predefined time under the work attendance state.Program is intercepted in operation on server, after the Data Receiving, through error correction, is put into behind the reconstructed database after the verification on the webpage, browses, consults for the user.
