Elevator car controller based on embedded STM32 chip

Abstract

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 is suitable for large-scale production and can serve many small and medium-sized elevator enterprises.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator car controller based on an embedded STM32 chip.

AI Technical Summary

Problems solved by technology

[0003] There are many types of elevator car controllers. However, traditional car controllers have slow computing speed and poor integration of microprocessor chips, resulting in poor real-time elevator car control and slow emergency response speeds, which can easily cause safety problems; another On the one hand, the car controller has a large number of peripheral components, the circuit is relatively complicated, and it is inconvenient to upgrade and maintain, which cannot meet the intelligent control requirements of modern elevators.
