本文介绍了一种电子密码锁的实现。该电子密码锁采用1一wire总线芯片Ds2401作为密匙，锁体采用高可靠性的单片机PIC16c63来完成密码识别和开锁控制，用I2C总线接口的EEPROM 芯片AT24c02来完成密码的存储和修改，可
掉电保存密码。整个系统安全可靠，稳定性高。-This paper introduces an electronic code lock realize. The electronic locks used one chip one wire bus Ds2401 as key, lock body for high reliability PIC16C63 microcontroller identification and password to complete the unlock control, with I2C bus interface EEPROM chip AT24C02 to complete the password storage and revised down to save the password. The entire system is safe and reliable, high stability.

功能：
1、作为下位机采集8255数据并将此数据通过通讯送出，
2、采集数据为BCD，先转换成二进制，处理后再转换成BCD
3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0
下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1-Features: 1, as under the 8255-bit machine data collection and communications sent through this data, 2, collected data for the BCD, first converted into binary, and then converted to deal with BCD 3, communication using methods 3, multi-machine communication, PC-fat address TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1
