Filled with elastic material, such as cotton, silk floss, sponge.In order to not influence the seat sense of people, the electric-controlled box is preferably arranged on inner core
One of corner position of cushion 1, in use, the apex angle of the built-in electric control box is put backwards, the buttocks of such people is basic
The electric-controlled box will not be sat on.
The housing 2 is set in 1 outer layer of inner core cushion, and the size of housing 2 is 35x35x3.2cm, in 1 top surface of inner core cushion
Pressure sensor 4 is provided between housing 2, the pressure sensor uses FSR resistance-type diaphragm pressure sensor.The pressure
Force snesor is bonded in 1 top surface of inner core cushion by double-sided adhesive, is also filled with elasticity between 1 top surface of inner core cushion and housing 2
Material, such as cotton, silk floss, sponge.
Be provided with battery and main control board in electric-controlled box, include on main control board MCU, pressure voltage transformation module,
NB-IOT transceiver module and power management module.
The MCU model STM32L431RCT6 can support 2 I2C interfaces, 3 UART interfaces, 3 SPI interfaces.
The pressure voltage transformation module uses MCP6001 single channel amplifier chip, and referring to attached drawing 3, the 4 of MCP6001 are drawn
Foot connects the signal output line of diaphragm pressure sensor, and 2 pins and 3 pins of MCP6001 meet GND, and 5 pins meet+3.3V, and 1 draws
External reference resistor Rf (Rf is in 1k Ω -100k Ω) between foot and 4 pins, 1 pin are signal output end, are connected to
The analog signal input pin of STM32L431RCT6.The pressure for being acquired diaphragm pressure sensor by pressure voltage transformation module
Force signal is converted to voltage signal and is input to STM32L431RCT6.
The NB-IOT transceiver module uses SN12, is connect with STM32L431RCT6 by UART interface, when work,
STM32L431RCT6 sends data to SN12 by UART, and SN12 is sent to by the base station NB-IOT again after receiving above data
Cloud platform, communication use UDP network protocol, working frequency range can be used 5 telecommunications 850MHz of Band or mobile using Band 8,
Connection 900MHz.
The power management module uses AMS1117-3.3V pressure stabilizing core module, and voltage input end connects battery, output
It is STM32L431RCT6, NB-IOT transceiver module SN12 and the confession of pressure voltage transformation module that end, which exports stable 3.3V voltage,
Electricity.
When work, after user sits down, STM32L431RCT6 detects the pressure after user sits down by diaphragm pressure sensor
Situation of change, after pressure change is more than given threshold, STM32L431RCT6 thinks to take down, then STM32L431RCT6 is logical
It crosses NB-IOT transceiver module and is sent out signal, notice remote server seat someone uses；If STM32L431RCT6 is examined

Between set 2.Temperature detection sensor uses DHT11, DHT11 to connect by I2C interface with STM32L431RCT6.When work, when
Pressure change is more than that temperature is more than after given threshold simultaneously for given threshold, and STM32L431RCT6 determines that someone sits down, then
STM32L431RCT6 is sent out signal by NB-IOT transceiver module, informs that remote server seat someone uses.If
Pressure change is more than given threshold, but (such as five minutes, setting five minutes be the heat in order to make human body within the set time
Be transmitted to temperature sensor) temperature is not above given threshold, then STM32L431RCT6 determine someone account for seat (school bag or its
He is placed on cushion article, therefore only pressure change, temperature are basically unchanged), at this point, STM32L431RCT6 alarms to control
Module sounds an alarm.Further, the alarm module uses voice broadcast module, and model uses VS1053B,
VS1053B is connect by SPI with STM32L431RCT6.The audio that the multiple voice prerecorded prompt and early warning are reminded
Audio source file is transmitted to VS1053B and is decoded by file deposit STM32L431RCT6 when needing voice broadcast, is driven
Loudspeaker makes a sound, and carries out voice prompting or voice alarm.
Illustrative description has been done to the utility model above, it should explanation, in the core for not departing from the utility model
In the case where the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc.
The protection scope of the utility model is each fallen with replacement.
