Easily there is to identify the problem of mistake in stricture of vagina identification, improves accuracy of identification and can cause again attendance recorder cost increase, the problem of fingerprint None-identified.Additionally, the mode that currently marketed attendance recorder generally uses netting twine carries out communication, needing to connect up separately, the attendance recorder also having uses wireless mode communication, but can increase product technology cost.
Wireless near field communication (NFC) technology is a kind of short distance high frequency wireless communication technology grown up from REID, in 13.56MHz frequency runs on 20 cm distance.Due to the advantage that the safety of NFC short haul connection is high, the method is very suitable for the application scenario such as identification, secure payment.Additionally, currently there is increasing individual mobile terminal product to start to support NFC communication technology.
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 attendance recorder based on NFC certification.
For solving the problems referred to above, this utility model attendance recorder based on NFC certification, including housing, it is characterized in that: the front panel of described housing is provided with NFC induction zone and human-computer interaction module, the back side of housing is provided with attaching plug, housing cavity is provided with microprocessor, NFC module, memory module, PLC communication module and AC-DC power module, the case inside of NFC induction zone is provided with the NFC antenna coil being connected with NFC module, microprocessor connects NFC module respectively, memory module and human-computer interaction module, microprocessor is connected with attaching plug by Power Line Carrier Communication Module, the input of AC-DC power module connects attaching plug, the outfan of AC-DC power module provides light current running voltage for described attendance recorder internal circuit.
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, SC1128 chip is connected with microprocessor, 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.
Pass through such scheme, this utility model uses NFC technique that work attendance person is carried out identification, there is advantage easy to use, that safety is high, use electric line carrier communication technology to realize the transmission of attendance data simultaneously, it is to avoid wiring cost and be wirelessly transferred the cost of chip.

Detailed description of the invention
Such as Fig. 1, shown in Fig. 2 and Fig. 3, attendance recorder based on NFC certification, including housing 1, it is characterized in that: the front panel of described housing 1 is provided with NFC induction zone 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 microprocessor, NFC module, memory module, PLC communication module and AC-DC power module, the NFC antenna coil being connected with NFC module it is provided with inside the housing 1 of NFC induction zone 2, microprocessor connects NFC module respectively, memory module and human-computer interaction module 3, microprocessor is connected with attaching plug 4 by Power Line Carrier Communication Module, the input of AC-DC power module connects attaching plug 4, the outfan of AC-DC power module provides light current running voltage for described attendance recorder internal circuit.
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 microprocessor, 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 microprocessor uses MSP430 single-chip microcomputer, and human-computer interaction module uses touch screen.
During use, only this utility model attendance recorder need to be inserted in supply socket.The alternating current that attaching plug 4 inputs is converted to low-voltage DC and is supplied to attendance recorder internal circuit by AC-DC power module.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 microprocessor is connected with SC1128 chip, thus realizes the electric lines of force that microprocessor accessed by attaching plug 4 and carry out communication, i.e. microprocessor with remote server and can carry out communication by PLC communication module and remote server.Mobile terminal with NFC module is brushed in NFC induction zone 2 by work attendance person, NFC antenna coil gets final product transceiving electromagnetic signals, i.e. NFC module within attendance recorder can be with communication of mobile terminal, receiving the authentication information of mobile terminal transmission and pass to microprocessor, the authentication information received is compared by microprocessor with the personal file in memory module.When comparative result is judged as work attendance success, microprocessor is by PLC communication module transmission work attendance success message to remote server, and microprocessor sends display content to human-computer interaction module 3 simultaneously.
