Description
Technical field
The present invention relates to the side in auto parts machinery field, more particularly to solar energy TPMS sensor wireless control main frame switching on and shutting down
Method and system.
Background technology
Solar energy TPMS (tire pressure monitoring) systems are for easy to use and power saving, main frame (solar energy TPMS main frames, similarly hereinafter)
Automatically into resting state after parking of automobile, Auto Power On monitors each tire pressure and temperature change when driving, allows user
The very first time knows abnormal tyre pressure, and timely full capping occurs to prevent unexpected.
In order to realize automatic opening/closing function prior art：During automobile starting master is waken up using main frame internal vibration switch interrupts
Machine is started shooting, and parking of automobile judges that parking of automobile main frame enters dormancy by monitors sensor signal time interval time-out.Current skill
Art has following four defect：
1st, vibroswitch structure is two bead impact trigger switch, because main frame is typically placed at console,
All the time the small noise for having bead impact to send in driving, damages user experience；
2nd, automobile is parked in by vibration and the big place of noise, such as road side or factory, and main frame may be opened by mistake often
Self-contained battery electricity is lost in machine, so depends merely on the solar panel installed on main frame and provides energy just not to self-contained battery charging
Enough, user is every to be needed manually to charge by USB charge ports after a while.
3rd, judge to stop by receiving sensor signal time-out, judge that the time is long, usual 10 minutes to 30 minutes, this
Sample also improves the unnecessary energy loss of main frame.
4th, the dormancy of prior art Main Engine Cut-Off does not receive sensing data, and being had a flat tire when parking can not in time more
Newly.
The content of the invention
Technical problem to be solved of the embodiment of the present invention is that there is provided a kind of solar energy TPMS tire pressure monitoring system main frames
According to sensor emission come tyre rotation state automatic switching method.It realizes the control of startup and shutdown, so that real
Parking receives the advantage for updating and receiving data and improving Consumer's Experience in the same old way while existing power saving.
In order to solve the above-mentioned technical problem, the embodiments of the invention provide a kind of solar energy TPMS tire pressure monitoring system main frames
According to sensor emission come tyre rotation state automatic switching method, methods described comprises the following steps：
Tyre inner pressure/the temperature of TPMS sensors timing detection in every 4 seconds installed in step S201, each tire/
Acceleration/battery voltage value；Acceleration is measured in different angle Action of Gravity Field according to tyre rotation centrifugal force and accelerometer
Angle value difference calculates the rotary state for obtaining tire：If the value that acceleration magnitude is tested every time does not change or small range changes
Think that tire is not rotated, it is dead ship condition to judge automobile；If instead the value that acceleration magnitude is tested every time is different and change is compared
It is larger, think rotary state during tire, it is driving states to judge automobile；If above measured value (tyre inner pressure/temperature/electricity
Cell voltage value and tyre rotation state) without change, then timing is transmitted to main frame in every 20 minutes by high-frequency RF, if measured value
Change and then launch wireless data at once to main frame；
Step S202, main frame are constantly in reception listening state in open state RF high-frequency receptions part, as long as there is sensing
Device launches high-frequency wireless signals, and main frame will receive and update display data, while judging each tyre rotation state：As each
Tire is all that rotary state then continues to keep open state；If each tire is off rotary state, main frame enters to enter the GATT
Machine state (is closed and shows that MCU enters dormancy).
Step S203, main frame are set to intermittence and receive listening state (i.e. in off-mode, MCU dormancy, RF HFSs
Receive monitoring a period of time secondary dormancy and monitor a period of time, such alternation again for a period of time), receiving in listening period such as
Fruit has sensor emission wireless signal, and RF high-frequency circuits wake up MCU (display screen is not opened) and receive RF high-frequency signals, update at once
Data simultaneously judge tyre rotation state：The dormancy again at once if tire does not rotate MCU；If tire is rotary state
MCU then opens display screen and enters open state at once.
Second aspect there is provided a kind of solar energy TPMS tire pressure monitoring systems main frame according to sensor emission come tyre rotation
The method of state automatic switching, it is characterised in that the system includes：
Computing unit：For sensor foundation tyre rotation centrifugal force and accelerometer in different angle Action of Gravity Field
Measurement acceleration magnitude difference calculates the rotary state for obtaining tire, and by high frequency wireless transmission to main frame；
Control unit：The tyre rotation state that sensor emission is come is received for main frame, such as each tyre rotation state is
Stop operating state, main frame then automatic shutdown；If any tyre rotation, main frame then Auto Power On.
