Description
Technical field
This utility model relates to a kind of novel finger print attendance recorder.
Background technology
Currently, fingerprint identification technology is the most highly developed, relevant fingerprint collecting and identification module the most industrialization, and price is the cheapest, uses fingerprint to carry out identification and has been widely used in the middle of daily life.Fingerprint attendance equipment has become numerous enterprises and has carried out the common tool of attendance record.On Vehicles Collected from Market, fingerprint attendance machine generally uses the mode of netting twine to carry out communication, needs to connect up separately, and the attendance recorder also having uses wireless mode communication, but can increase product technology cost.
Electric line carrier communication (Power line Communication,
PLC) it is the distinctive communication mode of power system, refers to utilize existing electric lines of force, by carrier system, analog or digital signal is carried out the technology of high-speed transfer.The maximum feature of electric line carrier communication is to need not again set up network, as long as live wire, just can carry out data transmission.
Utility model content
The problem that this utility model solves is to provide a kind of novel finger print attendance recorder.
For solving the problems referred to above, this utility model novel finger print attendance recorder, including housing, it is characterized in that: the front panel of described housing is provided with Fingerprint Identification Unit and human-computer interaction module, the back side of housing is provided with attaching plug, housing cavity is provided with processor, Flash memory module, PLC communication module and power module, and processor connects Fingerprint Identification Unit, human-computer interaction module and Flash memory module respectively, and processor is connected with attaching plug by Power Line Carrier Communication Module.
Based on above-mentioned, described power module includes current rectifying and wave filtering circuit and decompression voltage regulator, the input of current rectifying and wave filtering circuit connects attaching plug, and the input of decompression voltage regulator is connected with the outfan of current rectifying and wave filtering circuit, and the outfan of decompression voltage regulator is that processor is powered.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, novel finger print attendance recorder, including housing 1, it is characterized in that: the front panel of described housing 1 is provided with Fingerprint Identification Unit 2 and human-computer interaction module 3, the back side of housing 1 is provided with attaching plug 4, housing 1 inner chamber is provided with processor, Flash memory module, PLC communication module and power module, and processor connects Fingerprint Identification Unit 2, human-computer interaction module 3 and Flash memory module respectively, and processor is connected with attaching plug 4 by Power Line Carrier Communication Module.
Based on above-mentioned, described power module includes current rectifying and wave filtering circuit and decompression voltage regulator, the input of current rectifying and wave filtering circuit connects attaching plug 4, and the input of decompression voltage regulator is connected with the outfan of current rectifying and wave filtering circuit, and the outfan of decompression voltage regulator is that processor is powered.
Based on above-mentioned, described Power Line Carrier Communication Module includes coupling the SC1128 chip that circuit, power amplifier, band filter, pre-amplifier and power line carrier communication are special, coupling circuit is connected with attaching plug 4, SC1128 chip is connected with the serial ports of processor, the signal output part of SC1128 chip is connected with coupling circuit by power amplifier, and coupling circuit passes sequentially through band filter and pre-amplifier and is connected with the signal input part of described SC1128 chip.
Based on above-mentioned, described processor uses MSP430 single-chip microcomputer, and human-computer interaction module uses keyboard.
During use, only fingerprint attendance machine need to be inserted in supply socket.The voltage signal that attaching plug 4 is inputted by power module first carries out rectifying and wave-filtering, and then carries out lowering and stabilizing blood pressure, finally the voltage after lowering and stabilizing blood pressure is supplied to processor.The carrier signal received from attaching plug 4 is coupled on band filter by coupling circuit, the carrier signal received from coupling circuit is delivered to SC1128 chip through pre-amplifier by band filter, and the phase-modulated signal that SC1128 chip is sent by power amplifier simultaneously carries out power amplification and coupled circuit is coupled on attaching plug 4.Meanwhile, the serial ports of processor is connected with SC1128 chip, thus realizes the electric lines of force that processor accessed by attaching plug 4 and carry out communication, i.e. processor with remote server and can carry out communication by PLC communication module and remote server.When finger is pressed on Fingerprint Identification Unit 2 by user, the finger print information of collection is passed to processor by Fingerprint Identification Unit 2, finger print information is compared by processor with the personal file being saved in Flash memory module, if compare by; successful for work attendance message is sent to remote server.Fingerprint when None-identified user, user can also input password by human-computer interaction module 3, processor receives the encrypted message from human-computer interaction module 3, encrypted message is compared with the personal file being saved in Flash memory module, if compare by; successful for work attendance message is sent to remote server.
