Preferably, three pieces of plates are 2 centimetres of thickness, 20 centimetres long, 30 centimetres wide, and three pieces of plates pass through connection dress It sets 60 centimetres long after 1 connection is unfolded.

Preferably, the temperature control modules 4 include DS18B20 digital temperature sensor, detect ambient temperature, work as temperature When degree is lower than setting value, heater circuit is started by STC89C51 single-chip microcontroller 5, plate is heated, the heater circuit mainly by Resistive heater composition.

Preferably, the ultrasound examination module 2 uses ultrasonic wave HC-SR04 module, for emitting and receiving ultrasound Wave, for detecting linear distance of the user apart from ultrasound examination module 2, when user keep correct sitting posture when, the two it Between distance be higher than preset safe distance, when distance between the two be lower than setting value, STC89C51 single-chip microcontroller 5 start It is alarmed by the warning device that buzzer forms.

Preferably, the pressure detecting module 3 includes 40kg resistance strain type pressure sensor and HX711AD module, For detecting user to the application pressure of plate, when detecting that pressure is greater than the set value, STC89C51 single-chip microcontroller 5 starts by bee The warning device of ring device composition is alarmed.

Preferably, the digital display tube 7 shows the pressure for the pressure detecting module 3 that STC89C51 single-chip microcontroller 5 receives The temperature of value and temperature control modules 4.

Preferably, the battery and USB interface connection, battery and 5 control circuit phase of STC89C51 single-chip microcontroller Connection, for powering to control circuit.

The beneficial effects of the utility model are: effectively controlling a variety of function of the device using single-chip microcontroller as Master Control Center The realization of energy achievees the purpose that a plate is multi-purpose.The plate has the function of detecting distance, pressure and ambient temperature.With market Upper tradition sitting correction appliance is compared, and is had many advantages, such as that structure is simple, cheap, humanized, easy to carry, can is preferably User provides service.Using plank frame, and portable foldable, it is convenient for carrying.

Specific embodiment

Embodiment: as shown in Figure 1 to Figure 2, a kind of novel sitting posture correction plate, comprising: three pieces of plates pass through attachment device 1 links together three pieces of plates, and can fold, and ultrasound examination module 2 is mounted on the edge fixed bit of central flat It sets, the internal symmetry position that pressure detecting module 3 is mounted on both sides plate is pacified for detecting pressure size, temperature control modules 4 Mounted in the inside of central flat, STC89C51 single-chip microcontroller 5 is mounted on the inside of central flat, buzzer and battery and USB Interface 6 is mounted on the left upper of left planar, and digital display tube 7 is mounted on outside plate, reads data at any time for user, And it is electrically connected with STC89C51 single-chip microcontroller 5 between internal each module by conducting wire.
