Electronic control lock system, circuit and method based on dynamic encryption
The invention discloses an electric control lock system, circuit and method based on dynamic encryption, the electric control lock system comprises an electromagnetic valve assembly and a spring bolt, the electromagnetic valve assembly is used for controlling the spring bolt to stretch out and draw back, and the electric control lock system comprises a control module used for controlling the electromagnetic valve assembly; the control module comprises an MCU chip used for being in communication connection with the access control host and a driving unit used for driving the electromagnetic valve assembly to work, and the MCU chip and the access control host carry out information transmission through a direct current carrier unit; the access control host sends an encrypted message through the direct-current carrier unit, the MCU chip decrypts the encrypted message and identifies and judges whether the encrypted message is an unlocking instruction or not, and if the encrypted message is the unlocking instruction, the electromagnetic valve assembly is controlled to control the spring bolt to retract; the direct current carrier wave unit can integrate power supply and communication on a pair of power supply lines, the MCU chip can encrypt and decrypt communication content, the control circuit part is a circuit, and the lock tongue can be driven to retract to achieve unlocking only when the electric control lock receives an encrypted message, decrypts the encrypted message and successfully recognizes an unlocking instruction.
本发明公开了一种基于动态加密的电控锁系统、电路及方法，包括电磁阀组件和锁舌，电磁阀组件用于控制锁舌伸缩，包括控制模块，控制模块用于控制电磁阀组件；控制模块包括用于与门禁主机通信连接的MCU芯片和用于驱动电磁阀组件工作的驱动单元，MCU芯片与门禁主机通过直流载波单元进行信息传输；门禁主机通过直流载波单元发送加密报文，MCU芯片对加密报文进行解密，并识别判断是否为开锁指令，若为开锁指令则控制电磁阀组件控制锁舌回缩；直流载波单元可以实现将供电和通信集成到一对供电线上，MCU芯片可实现通信内容的加密和解密、控制电路部分电路，只有电控锁接收到加密报文然后解密并成功识别到开锁指令才会驱动锁舌缩回实现开锁。
