Specific embodiment

A kind of fingerprint as shown in Figs. 1-3 starts Question answering board, and this product includes hand disinfection 1 and fingerprint recognition component 2, Middle hand disinfection 1 includes clipboard ontology 3, shell 13 and control chip 4.Clipboard ontology 3 is embedded in shell 13, clipboard sheet Body 3 is made of transparent plastics, and 3 place horizontal plane of clipboard ontology is lower than the surface of shell 13, at this time 13 surface of shell and book It writes plate ontology 3 and forms a groove, this groove is induction zone, is also uniformly distributed between clipboard ontology 3 and the bottom of shell 13 There is the track identification sensor 6 that can scan handwriting trace, track identification sensor 6 is connected with 4 signal of control chip above-mentioned. Control chip 4 is located in shell 13, is provided with wireless communication unit, storage unit on control chip 4, wireless communication unit with deposit By the copper foil connection built in control chip 4 between storage unit, storage unit is additionally provided with the data for connecting terminal device Connecting hole 7, the data connection hole 7 can connect the common equipment such as computer or mobile hard disk.The effect of storage unit is pre- Deposit the handwriting trace of finger print information and the induction of storage track identification sensor 6.Hand disinfection 1 further includes second source (in figure It is not drawn into), second source is electrically connected in track identification sensor 6 and control chip 4.Setting wireless communication is single on control chip 4 The technology of member and storage unit has disclosed, such as Lian Fake chip applied by zigbee chip, mobile phone.

Fingerprint recognition component 2 includes that shell 8, capacitance type sensor 9(are also known as capacitive fingerprint sensing device), main control chip 10 and first power supply 11, the shell 8 be the cavity structure with opening 5, which is located at one end of shell 8, is being open at 5 Capacitance type sensor 9 above-mentioned is set, and capacitance type sensor 9 is also connect with 10 signal of main control chip in shell 8, this signal Connection is realized by the way of winding displacement.9 place plane of capacitance type sensor is lower than edge at the opening 5 of cavity structure, condenser type Sensor 9 is used to detect finger print information.In order to provide electric power to fingerprint recognition component 2, the first power supply 11 is also powered with condenser type It is additionally provided with sealing ring between the opening 5 of sensor 9 and main control chip 10, capacitance type sensor 9 and cavity structure, the sealing The material of circle is silica gel.

Main control chip 10 is also connect with control 4 signal of chip, and signal is wirelessly transmitted in connection selection between the two, Including modes such as bluetooth, WIFI, infrared rays.Main control chip 10 is also connected with a Rouser 12, which is distance Sensor, Rouser 12 is located on the path passed through when finger triggering capacitance type sensor 9 is arranged in, and the Rouser 12 Positioned at 8 surface of shell, the distance between range sensor detection object and range sensor, and distance signal is converted into telecommunications Number pass to main control chip 10.Signal connection is realized by winding displacement between main control chip 10 and Rouser 12.

Before using this product, the finger print information of user is stored in a storage unit by data connection hole 7, and sets Determine the wake-up distance of Rouser 12.Thumb is being pressed the capacitance type sensor at opening 5 when using this product by user On 9, when not in contact with capacitance type sensor 9, Rouser 12 detects the distance between hand and Rouser 12, works as the two The distance between be less than preset wake-up distance, the distance signal that Rouser 12 can will test is converted to electric signal and passes through winding displacement Main control chip 10 is passed to, main control chip 10 activates capacitance type sensor 9 and control chip 4 at this time, in thumb contact to electricity When capacity sensor 9, main control chip 10 can compare the fingerprint of user and the finger print information being pre-stored in storage unit, if Finger print information meets at this time, and control chip 4 activates track identification sensor 6, and clipboard ontology 3 of the user in groove is submitted a written statement to a higher authority It writes, during writing, the track identification sensor 6 of 3 lower layer of clipboard ontology records the track scanning of writing, and by rail Track scanning record in storage unit is passed through data connection after examination in storage unit by the scanning record storage of mark Hole 7 exports to terminal device and is read and made comments；When the fingerprint for touching capacitance type sensor 9 is not met with preset fingerprint When, main control chip 10 will not activate track identification sensor 6, and no matter user is write on clipboard ontology 3 in any at this time Hold, track identification sensor 6 not will record written contents, realizes the purpose that only specified people can be used, has prevented to examine Study disadvantage.Have much using the equipment that control chip 4 makes different processing according to different situations, such as in life often The smart phone seen, when user connects phone, mobile phone is closer apart from ear, is easy to appear maloperation phenomenon at this time (as greatly The face heaved when laughing at easily is hung up the telephone), therefore just need range sensor to adjust the distance in time and monitored, when appearance distance is excessively close When screen is automatically closed, to avoid the generation of maloperation phenomenon.

The above is the utility model preferred embodiment, is not constituted to scope of protection of the utility model Limitation.
