This specification provides a scheduling and control method and apparatus for an ALK-PEM hybrid hydrogen production system based on lifespan matching, belonging to the field of wind and solar power energy storage technology. First, a hybrid hydrogen production system is constructed, comprising at least a PEM electrolyzer, a first ALK electrolyzer, and a second ALK electrolyzer. Based on this hybrid hydrogen production system, by utilizing the waste heat from the PEM electrolyzer during system startup to preheat the second ALK electrolyzer, and by utilizing the circulating alkaline solution from the second ALK electrolyzer to preheat the first ALK electrolyzer when it stabilizes, the thermal shock damage during cold start-up of the ALK electrolyzer is effectively reduced. By introducing and utilizing the smaller-capacity second ALK electrolyzer to assist in sharing the fluctuating load borne by the PEM electrolyzer, the damage from wide load fluctuations during long-term operation of the PEM electrolyzer can be effectively reduced, thereby effectively extending the overall lifespan of the hybrid hydrogen production system and ensuring its safe and stable operation.

This utility model belongs to the technical field of access control card readers, specifically disclosing an access control card reader with RCC communication function, including an MCU control circuit, an RCC communication circuit, an RS485 communication circuit, a power supply circuit, an RF drive circuit, an RF antenna, a buzzer drive circuit, and a three-color backlight drive circuit. This utility model, by setting up an RCC communication circuit, enables the access control card reader to read the physical card number of a mobile phone SIM card, outputting it to the MCU via UART. The MCU then outputs the physical card number of the SIM card to the external access control controller via the RS485 communication circuit to open the door. This retains the current user habit of using mobile phones to swipe cards while avoiding security risks to access control management. Furthermore, the overall circuit design ensures stable operation of the access control card reader.

The specification provides a scheduling control method and device for an ALK-PEM hybrid hydrogen production system based on life matching, belonging to the technical field of wind-solar power generation and energy storage. First, a hybrid hydrogen production system including at least a PEM electrolyzer, a first ALK electrolyzer, and a second ALK electrolyzer is constructed. Based on the hybrid hydrogen production system, the waste heat during the operation of the PEM electrolyzer is used to preheat the second ALK electrolyzer during the system startup stage, and when it is stable, the circulating alkali solution of the second ALK electrolyzer is used to preheat the first ALK electrolyzer, effectively reducing the thermal shock damage of the ALK electrolyzer during cold start; by introducing and using the smaller capacity of the second ALK electrolyzer to assist in sharing the fluctuating load of the PEM electrolyzer, the wide load fluctuation damage of the PEM electrolyzer during long-term operation can be effectively reduced, thereby effectively prolonging the service life of the overall hybrid hydrogen production system, and ensuring the safe and stable operation of the hybrid hydrogen production system.
