Elevator car controller based on embedded STM32 chip

The invention discloses an elevator car controller based on an embedded STM32 chip. The elevator car controller comprises a micro processor module, an input module, an output module, a communication module and a power module. The micro processor module is the STM32 chip. The input module comprises a door opening and closing input part, a full load input part, a driver input part, an elevator locking input part and a floor button (lamp) circuit. The output module comprises a liquid crystal screen output part, a buzzer output part, a passing chime output part, a fan output part and an illumination output part. The communication module is a CAN communication circuit. The power module supplies a power supply to the whole controller. The elevator car controller is simple in structure, advanced in design, high in real-time controllability and response speed, and good in safety; and meanwhile, the number of peripheral components and parts is decreased, the production cost is reduced, and the elevator car controller
