Control circuit, electric chair and control method thereof

Abstract

The invention discloses a control circuit, an electric chair and a control method thereof. The electric chair comprises a power supply module, a microprocessor module, a motor interface, a stroke signal detection module, a direction control module and a voltage signal detection module. The microprocessor module records a motor stroke signal, the real-time position of a motor is obtained in combination with a motor motion direction signal, total travel and implementation position information are stored in an EEPROM of a chip, and meanwhile, a microprocessor module controls driving signal information of a motor in real time by processing a voltage feedback signal received from a voltage signal detection module, so that the running speed of the motor at each position is adjustable; and starting, stopping and speed adjustment at different positions of the motor are realized, so that the problems of jerking and unsafety during movement of the chair are solved, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a control circuit, an electric chair and a control method thereof. Background technique [0002] In order to attract customers and provide customers with a better experience, many businesses use electric chairs in many service areas, such as chairs in dental hospitals, shampoo chairs in barbershops, and massage chairs. The speed of electric chairs on the market is constant. Yes, there is a strong sense of frustration at the moment of starting and stopping. When the seat moves backward and the body is tilted back, the constant speed of movement brings the user an unsafe feeling of falling down. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, this application proposes a control circuit, an electric chair and its control method. Through the control system combinin...
