Background technology
At present, social Shang Ge enterprise and institution carry out record by attendance recorder to employee's situation on and off duty.Using two kinds of the most general modes is now exactly contactless card attendance recorder and fingerprint recognition for attendance checking machine.
Wherein contactless card attendance recorder is whether be effectively card further read in card information by reading if writing in advance that the contactless card such as magnetic card, IP phonecard identifies, and after judgement, work attendance information recording is got off.Although this mode is simple and convenient, exist card easily to lose, on behalf of the shortcoming of the phenomenon of checking card.
For fingerprint recognition for attendance checking machine, conventional fingerprint collecting equipment has three kinds, optical profile type, capacitive/inductive formula, biological RF-type at present.Wherein, optical fingerprint collector is fingerprint capturer the earliest, uses the most general.Optical fingerprint collector is long service time, low price, but it gathers fingerprint table layer texture image, has the fingerprint image discrimination of coverture very low to dirty finger and dry finger surface, and poor to the adaptive faculty of the environmental factors such as temperature.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of attendance recorder that not only has fingerprint identification function and also have speech identifying function, and two kinds of work attendance modes are used alternatingly, and have accuracy high, the fireballing feature of work attendance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of attendance recorder is provided, comprise body, front panel, the wiring board of rear panel and internal body, described wiring board comprises central processing unit, voice collecting unit, fingerprint collecting unit, audio signal processing circuit, fingerprint database, voice digital signal database, output unit, input block and communication unit, described fingerprint collecting unit, audio signal processing circuit, fingerprint database, voice digital signal database, output unit, input block is all connected with central processing unit with communication unit, described voice collecting unit is connected with audio signal processing circuit.
Further, described voice collecting unit is microphone, and described fingerprint collecting unit is biological radio-frequency fingerprint collector, and described output unit is TFT chromatic liquid crystal screen and loudspeaker, and described input block is for arranging button.
Further, described microphone, biological radio-frequency fingerprint collector, TFT chromatic liquid crystal screen, loudspeaker and button is set is all arranged on front panel.
Further, described communication unit is USB interface, Ethernet interface and RS232/RS485 interface.
Further, described USB interface, Ethernet interface and RS232/RS485 interface are all arranged on rear panel.
Further, described audio signal processing circuit comprises operational amplifier, wave filter and A/D converter, and described operational amplifier is electrically connected with voice collecting unit, for the sound signal receiving is amplified; Described wave filter is connected with operational amplifier, and the sound signal receiving after amplifying is carried out filtering; Described A/D converter is connected with wave filter, and the signal after accepting filter also converts digital signal to; Described A/D converter is connected with central processing unit, by conversion after digital data transmission to central processing unit.
The utility model not only possesses fingerprint recognition for attendance checking function, and it adopts biological radio-frequency fingerprint recognition technology, launches micro-radiofrequency signal by sensor itself, and the epidermal area that penetrates finger removes the lines of detection nexine, obtains best fingerprint image.In addition to dry finger, hands wet with perspiration refers to, the difficulty fingers such as dry finger are by can be up to 99.5%, and false proof fingerprint ability is strong, and the recognition principle of fingerprint sensor responds to people's corium skin, has fundamentally stopped the problem of artificial fingerprint.Differentiate the function of work attendance but also there is sound, as long as the voice signal prestoring in the voice signal of inputting from microphone and storer matches, then LCDs can show that whether coupling is successful, loudspeaker also can voice broadcast whether the match is successful, can carry out attendance record to this work attendance person as the match is successful.The mode of two kinds of work attendances is combined as a whole, and has greatly improved accuracy and the adaptability of work attendance, and simple to operate, speed is fast.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the preferred embodiments of the utility model attendance recorder.
Embodiment
Below in conjunction with drawings and embodiments, the utility model is elaborated.
Please refer to shown in Fig. 1, the preferred embodiments of the utility model attendance recorder comprises: the wiring board of body, front panel, rear panel and internal body.
Described wiring board comprises central processing unit, voice collecting unit, fingerprint collecting unit, audio signal processing circuit, fingerprint database, voice digital signal database, output unit, input block and communication unit.
Described fingerprint collecting unit is all connected with central processing unit with fingerprint database, and the finger print information collecting is passed to central processing unit by described fingerprint collecting unit, and central processing unit compares the information of the finger print information receiving and fingerprint database.Described voice collecting unit is connected with audio signal processing circuit, described audio signal processing circuit is connected with central processing unit, the audio frequency original signal collecting is transferred to audio signal processing circuit by described voice collecting unit, audio signal processing circuit changes into digital signal through amplification, filtering, conversion by original signal by original signal, then pass to central processing unit, central processing unit is connected with voice digital signal database, and the voice digital signal receiving and the data of the voice digital signal database pre-depositing are compared.
Described output unit, input block and communication unit are all connected with central processing unit.
Wherein, described voice collecting unit is microphone, and described fingerprint collecting unit is biological radio-frequency fingerprint collector, and described output unit is TFT chromatic liquid crystal screen and loudspeaker, and described input block is for arranging button.Described communication unit is USB interface, Ethernet interface and RS232/RS485 interface.
Described biological radio-frequency fingerprint collector adopts RF-type fingerprint sensor, its principle of work is very special, be made up of radio frequency and sensitive element array, in fact each member is an equivalent miniature antenna, and it transmits electric wave by people's finger to skin inner layer (skin corium) depths.The element of receiving portion to passback electric wave phase place carry out demodulation, the different responses of phase place fingerprint texture.Say in a sense, its principle is similar to the principle of work of radar, and, it can automatically regulate internal electric parameter adapt to the dry wet degree of finger, by finger pressure, age, etc. the variation of factor.Due to its unique principle of work, the fingerprint image collecting is corresponding to finger internal layer tool lived corium fingerprint texture, directly responsive to the outer skin of finger surface, and the material such as some fouls of effects on surface, oil stain, dust has penetration capacity.Its particular job principle makes it guarantee various types of fingers can collect desirable image under various service conditions, therefore has significant superior function.
