specific Embodiment approach 1

[0027] to combine figure 1 , 2 . The first pressure detection module, the second pressure detection module, the third pressure detection module, the fourth pressure detection module, the sitting posture detection module, the power supply module, the clock module, the button module, the voice reminder module, the display module, the wireless communication module, the intelligent terminal , place four sets of pressure sensors on the seat of the seat, judge whether the person in the seat is sitting upright by the pressure value detected by the four sets of pressure sensors, place an ultrasonic sensor on the back of the seat, and judge by the principle of distance measurement Whether the person in the seat is sitting upright, if not sitting upright or not sitting upright, a voice reminder will be given.

[0028] Among them, the output end of the first pressure detection module is connected to the input end of the main controller. The first pressure detection module adopts a CSY-...

[0039] to combine figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 illustrate this embodiment, and the main controller adopts ATmega1280 single-chip microcomputer. The ATmega1280 microcontroller is a high-performance, low-power AVR 8-bit microprocessor with an advanced RISC structure; a high-endurance non-volatile program and data memory; a JTAG interface; two independent frequency division 8-bit timer / counter with comparator and comparator functions; four 16-bit timer / counters with prescaler, compare function and capture function; four 8-bit PWM channels; 12 channels with programmable resolution 2 Up to 16-bit PWM channels; output comparison modulator; 6-way 10-bit ADC; byte-oriented 2-wire serial port; four programmable serial USARTs; SPI serial that can work in master / slave mode Line interface; programmable watchdog timer with independent on-chip oscillator; on-chip analog comparator; pin level change can cause interrupt and wake-up microcontroller.

specific Embodiment approach 3

[0040] to combine figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 illustrate this embodiment, the first pressure detection module, the second pressure detection module, the third pressure detection module and the first pressure detection module The four pressure detection modules all use CSY-3000 sensors. The CSY-3000 sensor is a resistance strain sensor with high precision, wide measurement range, long life, simple structure, good frequency response characteristics, can work under harsh conditions, and is easy to realize miniaturization, integration and variety diversification Etc. CSY-3000 sensor is a conversion device used to convert weight signal or pressure signal into electric quantity signal. The CSY-3000 sensor uses metal resistance strain gauges to form a full-bridge measurement circuit. Two strain gauges with the same stress direction are connected to the opposite side of the bridge, and the opposite strain gauge is connected to the adjacent side of the bri...

Abstract

The invention mainly relates to the field of life, and relates to an intelligent chair control system based on a single chip microcomputer; four groups of pressure sensors are placed on a seat of a chair, and whether a person on the seat sits upright is judged through pressure values detected by the four groups of pressure sensors; an ultrasonic sensor is placed on a chair backrest, and whether the person on the seat sits straight is judged through a distance measuring principle of the ultrasonic sensor, and if the person on the seat does not sit upright or straight, voice reminding is performed. The output ends of a first pressure detection module, a second pressure detection module, a third pressure detection module, a fourth pressure detection module and a sitting posture detection module of the intelligent chair control system are connected with the input end of a main controller, the output ends of a power source module, a clock module and a key module are connected with the inputend of the main controller, the output end of the main controller is connected with the input end of a display module, the output end of the main controller is connected with the input end of a voicereminding module, and an intelligent terminal is connected with the main controller through a wireless communication module.

Description

technical field [0001] The invention mainly relates to the field of life, and more specifically relates to an intelligent seat control system based on a single-chip microcomputer. Background technique [0002] Modern people are paying more and more attention to the education of their children. In addition to the knowledge and moral education of their children, parents also pay great attention to the cultivation of their children's healthy growth. Some seats on the market now only have basic support functions. , and some smart seats are dedicated to cars or massages. Therefore, for students, a smart seat is provided to help parents monitor their children's sitting posture, which is conducive to the healthy growth of children. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a kind of intelligent seat control system based on single-chip microcomputer, four sets of pressure sensors are placed on the seat of the seat...
