Large-current anti-reverse-connection and dual-power-supply automatic switching circuit of intelligent lock
The invention aims at disclosing a large-current reverse connection prevention and dual-power automatic switching circuit of an intelligent lockset, which relates to the technical field of intelligent lockset control and comprises a mains supply access end, a standby power supply access end, a circuit module and a circuit output end, the mains supply access end is electrically connected with the D pole of the first PMOS tube, the G pole of the first PMOS tube is grounded, the S pole of the first PMOS tube is electrically connected with the S pole of the second PMOS tube, and the D pole of the second PMOS tube is electrically connected with the circuit output end; the standby power supply access end is electrically connected with the D pole of the third PMOS tube, the G pole of the third PMOS tube is grounded, the S pole of the third PMOS tube is electrically connected with the S pole of the fourth PMOS tube, and the G pole of the fourth PMOS tube is grounded; the technical effect is that the first PMOS tube and the third PMOS tube are protected through polarity reverse connection prevention, when the polarity of the power supply is connected reversely, the power supply corresponding to the PMOS tubes is not conducted, and reverse connection prevention is achieved. And the first PMOS tube, the second PMOS tube, the third PMOS tube, the fourth PMOS tube, the NMOS tube and the diode are matched with one another, so that the mains supply or the standby power supply is switched on.
本发明的目的在于揭示一种智能锁具的大电流防反接及双电源自动切换电路，涉及智能锁具控制技术领域，包括市电接入端、备用电源接入端、电路模块及电路输出端；市电接入端电连接第一PMOS管的D极，第一PMOS管的G极接地，第一PMOS管的S极电连接第二PMOS管的S极，第二PMOS管的D极电连接电路输出端；备用电源接入端电连接第三PMOS管的D极，第三PMOS管的G极接地，第三PMOS管的S极电连接第四PMOS管的S极，第四PMOS管的G极接地；技术效果：第一PMOS管和第三PMOS管通过极性防反接保护，当电源极性接反时，PMOS管对应的电源不导通，实现防反接。第一PMOS管、第二PMOS管、第三PMOS管、第四PMOS管、NMOS管及二极管相互配合，实现导通市电或备用电源。
