摘要
在野外环境中往往不能方便地提供电源,传统由控制部分提供的电源,电子锁已不适用。介绍一种由手持部分提供电源,通过电源线完成通信功能的电子密码锁设计,解决了现场不能提供电源的问题。重点分析了发送电路、接收电路、倒向电路、电机保护电路以及系统的通信协议。该系统已在多个场所得到应用,其使用方便、安全可靠,具有一定的推广价值。
Since power supply can not be provided in the wild environment,the traditional electronic locks that is powered by control terminal is not applicable.The design of an electronic secure code lock which uses a hand terminal to provide power for the system and solves the problem that in the wild environment the power supply could not be provided is described.The signal sending circuits,receiving circuit,inverter circuits,protection circuit of motor and the communication protocol are analyzed emphatically.The lock has been applied in many places,and is converient,safe and reliable.
