Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, only show part related to the present invention in accompanying drawing but not full content.
Please refer to shown in Fig. 1 the key management system structural drawing based on recognition of face that Fig. 1 provides for the embodiment of the present invention.
Key management system based on recognition of face in the present embodiment comprises that camera 101, host computer 102, RS232 turn RS485 module 103, key controller 104 and boxes for keys 105, wherein, each drawer of described boxes for keys 105 is provided with a key controller 104 be mated.In the present embodiment, described boxes for keys 105 is the steel construction cabinet, and boxes for keys 105 is provided with 40 drawers.
Described host computer 102 is connected with camera 101, for setting up in advance all boxes for keys 105 users' face database, and when user's access key, control camera 101 and gather facial image, to mating with face database after this face image processing, if the match is successful, sending controling instruction turns RS485 module 103 to RS232.
In the present embodiment, described host computer 102 is selected personal computer (PC).Host computer 102 gathers boxes for keys 105 users' facial image in advance by camera 101, manually cut apart facial image, set up face database, and when user's access key, control camera 101 and gather facial image, cascade AdaBoost algorithm by Harr-like class rectangular characteristic detects human face region, adopt hidden Markov model to be described and to identify detected human face region, and the facial image after processing and face database coupling, if the match is successful, steering order is embedded in the Frame of Modbus agreement, turning RS485 module 103 by RS232 sends on the RS485 bus, wherein, carry source address in described Frame, destination address, the fields such as control command and CRC16 verification.It should be noted that, Harr-like class rectangular characteristic is the simple feature of a class, several rectangles, consists of.The AdaBoost algorithm is a kind of Weak Classifier being combined and ballot forms strong classifier according to nicety of grading separately machine learning algorithm.Hidden Markov model (Hidden Markov Model, HMM) be a kind of Statistic analysis models, the a kind of of Markov chain, its state can not observe directly, but can observe by the observation vector sequence, each observation vector is to show as various states by some probability density distribution, and each observation vector is to be produced by a status switch with corresponding probability density distribution.The Modbus agreement is to be now a brand of Schneider Electric Devices company by Modicon() invention in 1979, be the whole world first really for the bus protocol of industry spot.CRC is cyclic redundancy check (CRC) code (Cyclic Redundancy Check), is a kind of error check code the most frequently used in data communication field, it is characterized in that the length of information field and check field can be selected arbitrarily.
Described RS232 turns RS485 module 103 and is connected with host computer 102, for described steering order is sent to key controller 104 by the RS485 bus.
RS232 turns RS485 module 103 will embed the steering order in the Modbus protocol data frame, send to all key controllers 104 that connect on the RS485 bus.In the present embodiment, RS232 turns RS485 module 103, by SN75LBC184-TTL-RS485 interface driver chip, RS232 two paths of signals line is converted to the RS485 bus.The RS485 bus can connect at most 127 key controllers 104, so this system can also expand to two groups of boxes for keys as required.
Described key controller 104 turns RS485 module 103 with RS232, electric control lock is connected, for the destination address of described steering order and self address are mated, if it fails to match, do not carry out this instruction, if the match is successful, this instruction is resolved, according to analysis result, control electric control lock and open or close the boxes for keys drawer.
Destination address and self address that key controller 104 has the Frame of steering order to carry embedding are mated, if it fails to match, lose this Frame, do not carry out this instruction, if the match is successful, this instruction is resolved, take out data field, obtain control command, control electric control lock and open or close the boxes for keys drawer.In the present embodiment, described key controller 104 comprises that processor and connected power module, Ethernet interface, reset circuit, clock circuit, jtag interface, RS232 turn RS485 interface, electric control lock driving circuit, and processor is selected the STM32F103VET6 microprocessor.Key controller 104 reaches the send and receive purpose of serial data by the control to serial port setting and RS485 conversion chip, the Modbus agreement of usining is resolved Frame or packs as basis.
Below the course of work of the present invention is carried out to brief description: one, set up face database.Two,, when getting key, gather in time facial image by camera, relatively people's face data and the current facial image in face database, after coupling, ability unlocking key cabinet switch interface, the drawer that selection will be opened, the click switch button, just can open drawer, got key.Three, after taking out key, need to again gather facial image, after coupling, click the X button of this drawer, get final product closing drawers.
Technical scheme of the present invention has guaranteed the corresponding one by one, easy to use of key and user, and reliability is high, and extensibility is strong, realized scientific, the centralized management of key.
Note, above are only preferred embodiment of the present invention and institute's application technology principle.Skilled person in the art will appreciate that and the invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious variations, readjust and substitute and can not break away from protection scope of the present invention.Therefore, although by above embodiment, the present invention is described in further detail, the present invention is not limited only to above embodiment, in the situation that do not break away from the present invention's design, can also comprise more other equivalent embodiment, and scope of the present invention is determined by appended claim scope.
