Embodiment
As shown in Figure 1; a kind of traffic safety control system based on tire pressure monitoring; comprise tire pressure monitoring module 1, main control unit 2, display alarm module 3, program control brake module 4 and security protection module 5, a tire pressure monitoring module is all set in each tire of vehicle, its mounting structure as shown in Figure 4.The structure of this tire pressure monitoring module 2 as shown in Figure 2, comprise tyre pressure sensor 11, tire temperature sensor 12, microcontroller 13 and RF transceiver 14, wherein, tyre pressure sensor 11 and tire temperature sensor 12 adopt MPXY8300 sensor, and microcontroller 13 adopts arm processor.Tyre pressure sensor 11 is connected microcontroller 13 with tire temperature sensor 12, detect tire pressure and temperature information, and gathered by microcontroller 13, microcontroller 13 collects after relevant information, then the main control unit (ECU) that is sent to automobile via radio frequency network by connected RF transceiver 14 is processed.
Owing to having adopted MPXY8300 sensor, can carry out the switching of detecting pattern, for example, when the acceleration/accel of vehicle is after a period of time is 0, MPXY8300 sensor enters dormant state, thereby saving electric weight, reduces power consumption, and need to detect time, can wake up by the modes such as timer are set, its specific procedure flow process as shown in Figure 5.
Main control unit 2, after receiving tire pressure and temperature information, compares with the threshold value of setting, if find, occurs extremely needing to carry out safety guard-safeguard by calling other modules.When finding abnormal tyre pressure, first by display alarm module 3, carry out sound and light alarm, remind chaufeur and front vehicle to note.This display alarm module has comprised display unit and acousto-optic warning unit, and wherein display unit is for showing current detection data, and acousto-optic warning unit is used for sending sound and light alarm.
And the Main Function of program control brake module 4 is for can be in the moment of blowing out, take at once automatically brake measure to reduce the speed of a motor vehicle in driving process, with make up because of time of driver's reaction and caused opening time to the best affecting adversely of opportunity of slowing down.This module concrete structure as shown in Figure 3, comprise brake master cylinder 41, master cylinder 42, wheel cylinder 43, fuel accumulator 44, electrical motor 45 and the first electromagnetic valve 47, the second electromagnetic valve 48 and the 3rd electromagnetic valve 49, master cylinder 42 is respectively by the first electromagnetic valve 47, the second electromagnetic valve 48 and brake master cylinder 41, wheel cylinder 43 connects, fuel accumulator 44 is all connected with master cylinder 42 with electrical motor 45, wheel cylinder 43 connects fuel accumulator 44 by the 3rd electromagnetic valve 49, the main control unit 2 of vehicle respectively with the first electromagnetic valve 47, the second electromagnetic valve 48, the 3rd electromagnetic valve 49 is connected with electrical motor 45.
When the abnormal tyre pressure of burst being detected, main control unit 2 is closed the first electromagnetic valve 47 controls of locking chaufeur to brake, close the 3rd electromagnetic valve 49, prevent machine oil oil return, the second electromagnetic valve 48 of constantly folding simultaneously, lowers the speed of a motor vehicle, when the speed of a motor vehicle is less than setting value 40km/h, open again the first electromagnetic valve and the 3rd electromagnetic valve, recover the control of chaufeur to brake.The frequency of main control unit 2 folding the second electromagnetic valves 48 is initial by low frequency setting value, from low to high, until reach high frequency setting value, thus play the effect of ABS, prevent tire locking.Its concrete workflow as shown in Figure 6.
Security protection module 5 is used for the running of control engine, and when tire state occurs when abnormal, the electric signal by close the throttle is worked engine stop, avoids chaufeur because flurried or lack experience, in the accident that wrong step on the gas pedal causes under desperation.This module is that access control circuit 51 forms on common engine load sensor, and its structure as shown in Figure 7.Under abnormal condition, initiatively make short circuit between E2 and IDL, voltage is 0, transmits signal that a throttle gate do not open to main control unit, makes main control unit be judged as not oil spout, even if the violent step on the accelerator of chaufeur maloperation can not accelerate yet.When detect abnormal tyre pressure time, by relay, initiatively connect E2 and IDL.Relay is selected dynamic circuit connector type (often opening) (H type), and coil no power Shi Liang contact disconnects, and energising Hou,Liang Ge contact is just closed.To close the phonetic prefix " H " of word, represent.Only need to just can control by a relay, with low cost.
In addition, security protection module 5 also comprises emergency unit, and this emergency unit connects the navigating instrument of vehicle; utilize the residue function of navigating instrument; associating safety control module, when generation is abnormal, the distress signal that the transmission of emergency unit comprises location information is to the long-range center of seeking help.
