Description

A kind of palmmprint identification suitcase

Technical field

The utility model relates to electronic technology field, and a kind of palmmprint identification suitcase is provided.

Background technology

Suitcase is the article that often use in our daily life, and it is used for out on tours and carries bank note, precious article, daily necessities, and current suitcase adopts machinery or electronic lock or cipher switch etc. usually; The stolen molecule of these traditional anti-theft techniques is cracked then; Thereby make some lawless persons often remove to steal suitcase, the user suffers tremendous loss, and existing part suitcase also has the identification of employing palmmprint to guard against theft; But whole Palm Print Recognition System power consumption is big; And also have part to adopt increase solar energy electroplax to solve these problems of asking, but its cost is high, the solar energy electroplax is installed inconvenient.

Summary of the invention

The purpose of the utility model is the deficiency to prior art, and a kind of palmmprint identification suitcase is provided.

The utility model is for realizing that above-mentioned purpose adopts following technical scheme:

A kind of palmmprint identification suitcase, the palmmprint identification module, electric lockset, the casing that comprise casing, are arranged in the casing are opened switch, it is characterized in that, also comprise the power switch that is used to control power module,

Said palmmprint identification module comprises; Dsp processor; The palmmprint pick-up transducers that is connected with dsp processor, logical transition PLCD module, FLASH, SDRAM, MCU control module, power module; The LCD MODULE, the keyboard input module that are connected with the MCU control module, said palmmprint pick-up transducers is connected with logical transition PLCD module;

Also comprise the relay that is used to connect electric lockset and dsp processor, said relay drives the control signal control electric lockset switch that receives dsp processor;

Said palmmprint pick-up transducers is arranged on the lid of casing front.

The utlity model has following beneficial effect:

One, the utility model has higher security with respect to traditional portable combination lock, uses more reliable, and easy to use.

Two, the utility model adopts power switch that behavior adjustment management is carried out in the power supply of whole system, and shutdown system is supplied power when not working, and has increased the power using time of whole suitcase.

Three, the utility model technology maturation is made simply, and is durable in use, safeguards simple and easy.

Description of drawings

Fig. 1 is the utility model structure chart;

1-power switch, 2-line pick-up transducers, 3-casing are opened the switch palm, 4-key-press module, 5-LCD MODULE among the figure.

The specific embodiment

The DSP core processor of the utility model adopts the key control unit of BF531 model as system; Be used to gather the palmmprint pick-up transducers employing VO7620 model of palmmprint information; Power module is that system provides direct current and exchanges, and the memory that the utility model adopts comprises SDRAM memory and FLASH memory, and SDRAM adopts K4S161622H; Be used for being stored in the interim palmmprint figure of palmmprint collection and processing; FLASH adopts SST39VFl601, is used for storing the algorithmic code and the palmmprint data of palmmprint identification, when reset signal occurring, accomplishes the process of the bootstrap loading that powers on simultaneously.Man-machine interaction is made up of key-press module and LCD MODULE, is used to be provided with palmmprint identification module duty and shows job information, and it also is provided with UART interface data transmission interface and is used for system and communicates by letter with PC.The palmmprint lockset is made up of motor and palmmprint lock, sends rotating and reverse of signal control motor by DSP, the switch of control lock palmmprint lock.

The utility model work is; The palmmprint identification module at first receives user's palmmprint registration; In use, the palmmprint identification module receives the palmmprint information of using this, and dsp processor compares the duty that electric lockset is controlled in the back with the palmmprint information and the current palmmprint information that collects of original registration.

It is the power switch of whole system power supply that the utility model is provided with the control power module, and with switch opens, power module is this system's power supply when the user uses; Accomplish work such as palmmprint identification or palmmprint registration, after suitcase is locked, promptly in not opening this process; Whole system is in the standby; Cause the power supply waste of electric energy, at this moment can power switch be closed saves energy; Treating to open suitcase, to open power switch be whole system power supply, accomplishes palmmprint identification and can open suitcase.

Claims (1)
