所述的指纹采集模块1为滑动式指纹传感器。 The fingerprint acquisition module 1 is a slide-type fingerprint sensor.

指纹识别系统对功耗和体积要求都较高,所以选用滑动式指纹传感器,该传感器具有活体识别能力,可以杜绝伪造指纹的使用。 Fingerprint recognition systems have high power consumption and volume requirements, so use the slide-type fingerprint sensor that has the ability to identify the living body, the fingerprint can be used to prevent forgery. 指纹比对部分选用TI的DSP为核心控制芯片,具有功耗低和可靠性高的优点。 Fingerprint matching part of the selection of TI DSP core control chip with low power consumption and high reliability advantages. 遥控器可存储10枚指纹,使用2 节7号碱性电池作为电源,可开启3000次以上。 The remote controller 10 may store the fingerprint, using two AAA alkaline batteries, can open more than 3000 times.

无线双向通讯:采用近距离数据传输解决方案,可保证复杂环境下的50米有效距离。 Wireless two-way communication: the use of short-range data transmission solution, the effective distance of 50 meters, ensured in complex environments.

数据加密:采用DES、 3DES或AES对称加密算法,每个汽车的指纹遥控器和配套的车载控制器使用唯一的一对密钥,通过每次加密不同的随机数据的方式实现截获数据重发的方式是绝对无效的,而根据明文数据和密文数据猜测密钥同样无法实现。 Data Encryption: uses DES, 3DES or AES symmetric encryption algorithm, the fingerprint of each car and ancillary vehicle remote controller using a unique pair of keys, each implemented by way of intercepted encrypted data different random data retransmission way is absolutely null and void, but the same can not guess the key is to realize the plaintext and ciphertext data data.

5主控芯片采用STC微控制器,同样可以选用与其功能和特性类似的芯片,比如MOTOROLA , AV民SST, PIC,ATMEL等公司的产品,但是在选用上应该注意车载应用(大震动,强干扰)这一特定的环境。 5 Master STC microcontroller chip, you can use the same functions and features similar to its chips, such as MOTOROLA, AV people SST, PIC, ATMEL and other products, but it should be noted in the selection of vehicle applications (big shock, strong interference ) this particular environment.

处理器可以采用TI, AD等公司的DSP产品,由于指纹图像处理的过程较为复杂,所以应尽量选用性能更高的器件。 The processor may be employed TI, AD DSP companies such products, since the fingerprint image processing process is complicated, we should try to use higher-performance devices. 近来由于ARM内核产品的广泛推广,因此在市场上可以比较好的采购到这类产品,在性价比方面具有很大的优势,所以ARM的选择也符合系统设计要求。 Recently, due to the extensive promotion of the ARM core products, so the market may be better to purchase these products, it has great advantages in terms of cost, so ARM is also consistent with the choice of system design requirements.

指纹采集模块采用ATMEL的AT77系列,同样可以选用更加小型化和性能优异的指纹采集模块和产品,如FPS系列,FDU系列等。 The fingerprint module uses ATMEL AT77 series, can also choose more compact and excellent in performance and product fingerprint acquisition module, such as FPS series, the FDU series.

无线收发模块的选择应该遵循功耗低,传输距离远,同国家的无线标准不相冲突的原则。 Select the wireless transceiver module should follow a low-power, transmission distance, with the country's wireless standards do not conflict with the principles. 可以选用的产品较多,比如:WIRELESS的IA系歹U, NORDIC公司的nRF系列等。 We can use more of the product, such as: WIRELESS The IA series of bad U, NORDIC company nRF series.

指纹存储设备没有特别的要求,常见的原厂FLASH和EEPROM符合要求, 但是由于是和微处理器进行连接,所以只需注意接口规范即可。 Fingerprint storage device does not have special requirements, common original FLASH and EEPROM meet the requirements, but because it is a microprocessor and connected, so just pay attention to the interface specification. 操作过程可以分为:指纹录入,指纹对比,指纹删除。 Operation can be divided into: fingerprint input, a fingerprint comparison, fingerprint deletion.

典型的指纹录入过程如下:按动添加用户按钮,微控制器2将添加指令发送给微处理器3。 Typical fingerprint input process is as follows: Add User button pressed, the microcontroller 2 Add command to the microprocessor 3. 微处理器3首先采集系统管理员的指纹并同存储模块5中的模板进行比对,在比对成功之后,采集新添用户的指纹将其转化为模板并存放其中。 The microprocessor 3 first acquisition system administrator fingerprints and compare on the same template storage module 5, after the comparison is successful, the acquisition added a new user's fingerprint template and convert it to store them.
