Description

Intelligent control system for gesture recognition of dentist operation platform

Technical Field

The utility model relates to the field of medical equipment, specifically a dentist operation platform gesture recognition intelligent control system.

Background

The existing dental operation platform control is based on button type control, generally mechanical buttons or soft touch buttons, and the implementation mode has the advantage of low cost. But there is great uncertainty in terms of medical safety requirements and the operation is inconvenient. Due to the particularity of the medical system, when a dentist performs an operation, the upper half of the dentist is in a relatively sterile state space, and a doctor often needs to help a person beside the dentist to adjust the operation platform when the doctor performs oral treatment on a patient. Sometimes, when no one is around, the glove on the handle is taken down and then the small button on the operation platform is pressed, sometimes, the glove uses the tip of the arm, elbow and wrist to touch the small button when the operation platform is inconvenient, sometimes, the small button is too small and too close to each other, the operation is not easy when the glove is used by the tip of the arm, and the operation is successful after trying for several times, which brings great inconvenience to the work.

Detailed Description

In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.

As shown in fig. 1, the intelligent control system for gesture recognition of a dentist operating platform comprises a controller 8, the controller 8 is connected with and controls a shadowless lamp 6 through a circuit shadowless lamp 6, the controller 8 is positioned in a platform control cabinet 7 in a sensor recognition window, the controller 8 is controlled by a gesture recognition sensor, the controller 8 is connected with the shadowless lamp 6, the controller 8 is connected with a lifting speed reduction motor combination 3 through a circuit, the lifting speed reduction motor combination 3 is connected with a seat 10 through a lifting lead screw 4, the controller controls the lifting lead screw 4 through the lifting speed reduction motor combination 3 so as to control the up-and-down movement of the seat 10, the controller is electrically connected with a rotating speed reduction motor combination 5, the controller controls the rotation of the seat 10 through the rotating speed reduction motor combination 5, the rotating speed reduction motor combination 5 is connected with the seat 10 through a sliding table 2, and the controller is electrically connected with a backrest adjusting motor of the seat 10, the backrest adjusting motor 1 is meshed with a gear on the lower end shaft of the backrest 9 through a gear.

The system employs a device that controls the dentist platform based on a gesture recognition sensor. The system adopts STM32F103 as a control CPU, a 3.2-inch TFT 16-bit true color display screen is used for man-machine interaction display, and interface circuits such as the CPU, a sensor and the like enter an instruction receiving state after being initialized.

As shown in fig. 2, the device comprises an internal self-contained LED driver, a sensor sensing array, a target information extraction array and a gesture recognition array. The sensor during operation passes through inside LED driver, drives infrared LED and outwards launches infrared signal, and when the sensor array detected the object in effectual distance, target information extraction array can carry out the acquisition of characteristic raw data to the detection target, and the data of acquireing can exist in the register, and gesture recognition array can carry out identification process to raw data simultaneously, deposits the gesture result in the register at last, and the user can read raw data and gesture recognition's result according to the I2C interface.

As shown in fig. 3, the lcd displays the corresponding prompt message. In the function definition design, the control function of each gesture is determined, and when a finger waves in front of a gesture recognition sensor window, a CPU outputs a corresponding negation signal and turns on a shadowless lamp through a circuit such as a relay triode. When the hands are waved again, the CPU outputs a reverse level signal to turn off the shadowless lamp through the driving circuit.

As shown in FIG. 4, when the finger slides from right to left in front of the gesture recognition sensor window, the left slide gesture is recognized, the CPU outputs a corresponding high level control signal to drive the backrest to make a backward tilting action through the relay triode, when the finger slides from left to right, the right slide signal gesture is recognized, and the CPU outputs a corresponding low level control signal to make a lifting action through the drive circuit backrest.

As shown in fig. 5, when the finger turns left or right in front of the sensor window and the sensor recognizes the signal, the CPU outputs a high/low level signal to control the rotation of the gear motor assembly to drive the seat to turn left or right.

As shown in fig. 6, when the finger slides from bottom to top, the sensor recognizes the upward sliding signal, the CPU outputs a high level signal to control the lifting gear motor to drive the seat to move upward, and when the finger slides from top to bottom, the sensor recognizes the downward sliding signal, the CPU outputs a low level signal to control the lifting gear motor combination to drive the seat to move downward.

When the finger approaches the sensor window from a far position, the sensor recognizes a forward signal, the CPU outputs a level signal of the last action, the seat is enabled to continuously move correspondingly, when the finger leaves from the position close to the sensor window outwards, the sensor recognizes a backward signal, the CPU outputs an invalid level signal, and the continuous action signal is closed.
