摘要
为了对出租车计价进行有效地管理,在分析现有出租车计价传感器漏洞的基础上,采用PIC12C508A和PIC12CE518A单片机提出了出租车计价加密传感器的加密模型和系统结构模型,完成了密码传感器系统中加密器和解密器软硬件系统设计.加密后的密码传感器提高了出租车计价器计费的准确性和安全性,解决了现有出租车计价器可靠性不高和难以实现统一管理的难题.
The encryption is applied to the sensor of taximeters. It provides encrypt models and system structure model of encrypting sensor of taximeters based on analyzing bugs of sensor of existing taximeters. Hardware of encrypting machine, decoding machine is designed by using PIC12C508A、PIC12CE518A and INTER8031. Secret code sensors after encrypting raise accuracy and security of taxi charges greatly, and solve existing difficult problem of reliability and management in unison.
