摘要：To meet the needs of the general parking equipment with high integration, fully functional control system, we design a controller based on STM32F103 series microprocessor used in Multi-layer parking equipment, with SD card, NRF and other module interface. To ensure the stability of the controller, all of the input interface, relay output interface and the power supply part are isolated, smoothed and other necessary processing; The controller can be performed RS485, CAN bus communication, also with voice alarm, LCD display. After the necessary tests, combined with practical work of the three layers and six places parking equipment, then verified the reliability and practicability of the controller.
