The invention is suitable for the field of electronic and electric appliance technology improvement, and provides a backup unlocking and locking method, which comprises the following steps: S1, distributing a channel on a low-frequency chip as a backup unlocking and locking channel; s2, a controller is awakened through an external opening handle, and a remote control key is searched through a signal output by a low-frequency antenna; s3, judging whether a remote control key high-frequency signal response is received within a preset time or not; s4, an alternating magnetic field generated by the alternating voltage of the low-frequency antenna enables an LC circuit in the key to generate voltage to supply power to the key Transponder; s5, after obtaining the electric energy, the Transponder sends a radio frequency signal to the controller at a high frequency; s6, after receiving the high-frequency signal, the controller carries out demodulation and decoding and carries out key authentication; and S7, after the controller authenticates the key, the controller drives a door lock motor to unlock and lock. The backup unlocking and locking mode is changed from complexity to simplicity, and the perception experience of a user is improved.

    本发明适用于电子电器技术改进领域,提供了一种备份解闭锁的方法,包括:S1、在低频芯片上分配一路通道作为备份解闭锁通道;S2、通过外开手柄唤醒控制器通过低频天线输出信号寻找遥控钥匙;S3、判断在预设时间内是否收到遥控钥匙高频信号响应;S4、低频天线交变电压产生的交变磁场使钥匙内部LC电路产生电压给钥匙Transponder供电;S5、Transponder获得电能后以高频率发送射频信号给控制器;S6、控制器接收到高频信号后进行解调解码并进行钥匙认证;S7、控制器认证钥匙通过后驱动门锁电机进行解闭锁。备份解闭锁方式由繁琐到简洁,提升用户感知体验。
