Description
[technical field]
The utility model relates to a kind of recognition system, especially relates to the police investigation device of a kind of fingerprint recognition.
[background technology]
Known, public security organ is in the process of investigating the case, if the fingerprint that suspect stays can be extracted, be equivalent to obtain the direct-path of solving a case, but the fingerprint individual verification terminal also do not carried with at present, so just often because can not compare at scene, thus miss the best opportunity of arresting, cause suspect to escape.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses the police investigation device of a kind of fingerprint recognition, the utility model downloads unique point template by investigation device terminal on PC host computer, then carries out fingerprint comparison to the personnel at scene, thus reaches the object of fingerprint recognition.
In order to realize described goal of the invention, the utility model adopts following technical scheme:
The police investigation device of a kind of fingerprint recognition, comprise PC host computer and investigation device terminal, described PC host computer is made up of PC main frame, application layer software and online Fingerprint Processing Module, is provided with application layer software and online Fingerprint Processing Module in PC main frame; Investigation device terminal is formed by investigating device body, battery, storer, fingerprint collecting sensor and validator, battery, storer, fingerprint collecting sensor and validator is provided with in investigation device body, the outside of investigation device body is provided with USB interface, and PC host computer is inserted in the USB interface of investigation device body exterior by USB data line and is connected with investigation device body.
Described investigation device terminal is provided with power switch, hummer and Vib., and power switch controls the opening and closing of battery, and battery is connected with power-supply system, and power-supply system is respectively storer and validator provides energy.
Be provided with usb protocol controller in described investigation device body, usb protocol controller is connected with storer with power-supply system, USB interface respectively.
Described validator is the SDRAM of 16M.
Described storer is the Flash of 2M.
Described fingerprint collecting sensor is connected with storer by MCU.
DSP technology is adopted between described storer and validator.
Owing to have employed technique scheme, the utility model has following beneficial effect:
The police investigation device of a kind of fingerprint recognition described in the utility model, comprise worktable, cutting bed, slideway, travelling belt, weighing apparatus and tool box, on PC host computer, unique point template is downloaded by investigation device terminal, then fingerprint comparison is carried out to the personnel at scene, thus reach the object of fingerprint recognition; The police investigation device of a kind of fingerprint recognition described in the utility model, structure is simple and practical, operates more convenient, greatly improves the efficiency of fingerprint individual verification, provides great help for arresting suspect.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In figure: 1, PC host computer; 2, device terminal is investigated.
[embodiment]
By explanation the utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model.
The police investigation device of a kind of fingerprint recognition by reference to the accompanying drawings described in 1, comprise PC host computer 1 and investigation device terminal 2, described PC host computer 1 is made up of PC main frame, application layer software and online Fingerprint Processing Module, is provided with application layer software and online Fingerprint Processing Module in PC main frame; Investigation device terminal 2 is made up of investigation device body, battery, storer, fingerprint collecting sensor and validator, battery, storer, fingerprint collecting sensor and validator is provided with in investigation device body, the outside of investigation device body is provided with USB interface, and PC host computer is inserted in the USB interface of investigation device body exterior by USB data line and is connected with investigation device body; Described investigation device terminal 2 is provided with power switch, hummer and Vib., and power switch controls the opening and closing of battery, and battery is connected with power-supply system, and power-supply system is respectively storer and validator provides energy; Be provided with usb protocol controller in described investigation device body, usb protocol controller is connected with storer with power-supply system, USB interface respectively; Described validator is the SDRAM of 16M; Described storer is the Flash of 2M; Described fingerprint collecting sensor is connected with storer by MCU; DSP technology is adopted between described storer and validator.
Implement the police investigation device of a kind of fingerprint recognition described in the utility model, first the fingerprint of suspect is entered in PC host computer 1 in use, then through image procossing and cutting out, the template of final morphogenesis characters point, so just can the template of unique point be downloaded in investigation device terminal by USB data line, 2, investigation device terminal needs the unique point template required for download get final product and return success to PC main frame, investigate device terminal 2 to be charged by USB data line simultaneously, make battery be full of electricity can use, at the scene during comparison, the fingerprint of people is only needed to be placed on fingerprint capturer, finger print information is penetrated validator by MCU by fingerprint capturer, unique point template in finger print information and storer is compared by DSP technology by validator, buzzing and vibrations are carried out if there is the hummer in investigation device terminal 2 during the same fingerprint and Vib., people's police will be reminded like this, thus successfully suspect is arrested, battery adopts lithium polymer battery, battery capacity is not less than 900mAh, and USB interface supports vehicle-mounted charge, 220V alternating current charging and USB and the original charging modes of battery, and to dry finger, microdactylia line and mixed and disorderly fingerprint can identify efficiently, percent of pass is greater than 85%.
The non-detailed portion of the utility model is prior art.
