Detailed description of the invention
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation, some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that not departing from spirit and scope of the present utility model, can revise described embodiment by various mode.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
As shown in Figure 1, tyre pressure sensor automatic positioning equipment, comprise the sensor 1 being arranged on respectively on four wheels of automobile, described sensor 1 comprises MCU microcontroller, X-axis acceleration pick-up, Z axis acceleration pick-up, pressure sensor and wireless launcher, X-axis acceleration pick-up detects wheel direction of travel acceleration/accel, and Z axis acceleration pick-up detects wheel vertical direction acceleration/accel, the front end of automobile or tail end are provided with the receiving wire 2 of the wireless data that receives wireless launcher transmitting, described receiving wire 2 is connected with signal processor 3, described receiving wire 2 is arranged on the front bumper or rear bumper of automobile, and in this enforcement, signal processor 3 is arranged on rear bumper, the signal output part of described signal processor 3 is connected with the Screen display system 4 in car, as shown in Figure 2, described Screen display system 4 comprises the near front wheel tire pressure display space, left rear wheel tire pressure display space, off front wheel tire pressure display space and off hind wheel tire pressure display space, described Screen display system 4 is provided with and described the near front wheel tire pressure display space, described left rear wheel tire pressure display space, described off front wheel tire pressure display space and described off hind wheel tire pressure display space the near front wheel alarm lamp 51 one to one, left rear wheel alarm lamp 52, off front wheel alarm lamp 53 and off hind wheel alarm lamp 54, in the time that the tire pressure of tire is too high or too low, signal processor 3 is controlled alarm lamp corresponding to this tire and is lighted warning.
The detection data of the X-axis acceleration pick-up of each sensor 1, Z axis acceleration pick-up, pressure sensor are one group, four sensors produce four groups of data, signal processor 3 judges that according to the detection data of sensor this tire is revolver or right wheel, then be front-wheel or trailing wheel according to the power judgement of signal, finally the tire pressure data of accuracy of judgement are shown in the relevant position of Screen display system 4, make chaufeur can see intuitively and accurately tire pressure data, grasp in time the tire pressure condition of motor tire; Sensor 1 26S Proteasome Structure and Function of four tires is identical, can accomplish normalisation batch manufacturing, reduces production costs and maintenance cost.
Introduce a kind of localization method based on above-mentioned tyre pressure sensor automatic positioning equipment below, comprise the steps:
Step 1, X-axis acceleration change and Z axis acceleration change that the MCU microcontroller of sensor detects according to X-axis acceleration pick-up and Z axis acceleration pick-up calculate tyre rotation direction, and the tire pressure data that the ID of result of calculation, sensor and pressure sensor detect are launched by wireless launcher;
Step 2, receiving wire receives the data of wireless launcher transmitting and is transferred to signal processor;
Step 3, the direction that signal processor 3 advances according to automobile and the direction of tyre rotation judge the orientation, left and right of corresponding tire, and judge left and right wheels corresponding to corresponding tire pressure data;
To set vehicle traveling direction be X-axis forward, Z axis acceleration/accel rises and X-axis acceleration/accel is greater than the revolver of zero the corresponding left-hand revolution of data, and Z axis acceleration/accel rises and corresponding the right of clickwise of the minus data of X-axis acceleration/accel taken turns; Z axis acceleration/accel declines and X-axis acceleration/accel is greater than corresponding the right of clickwise of zero data and takes turns, and Z axis acceleration/accel declines and the revolver of the corresponding left-hand revolution of the minus data of X-axis acceleration/accel;
Step 4, signal processor 3 is the power of tire pressure signals and/or acceleration signal relatively, taking the position of receiving wire as benchmark, the more intense near tire of signal respective distances receiving wire;
Suppose that described receiving wire 2 is arranged on the rear bumper of automobile, the corresponding automobile back wheel of data that the intensity of tire pressure signal and/or acceleration signal is large, the corresponding vehicle front of data that signal strength is little;
Receiving wire 2 is data of sending for receiving sensor 1.Because receiving wire 2 is different apart from the distance of two sensors 1 of front-wheel and two sensors 1 of trailing wheel, judge front and back wheel by signal strength, sensor 1 from receiving wire 2 more close to, the intensity of wireless signal is stronger.
Step 5, signal processor 3 is transported to Screen display system by corresponding tire pressure data and shows.
By said method, can judge tire corresponding to corresponding tire pressure data by acceleration information very accurately, and corresponding tire tire pressure data are shown at Screen display system 4, accuracy of judgement is quick.
Signal processor 3 judges that by the rotation direction data of identifying the working direction (automobile is the forward gear of hanging at present or retreats shelves) of automobile and send when front sensor 1 tire is left or right.
Localization method based on above-mentioned tyre pressure sensor automatic positioning equipment is decomposed into two steps in location, left and right and location, front and back and completes, and realizes four-wheel location.Location, left and right imports algorithm by the acceleration/accel of X-axis and Z axis and draws position, left and right, and location, front and back is that the relation of processing front and back position and signal strength by receiving receiving wire 2 draws.Derivation and the conclusion of location, following summary left and right.
Suppose that sensor bears centripetal force acceleration/accel a and gravity acceleration g, for analyze just, suppose that acceleration due to gravity is larger.If Fig. 3 is force analysis figure, we have analyzed the stressing conditions (A, B, C, D stress point) of four specific positions.
1. hypothesis wheel left-hand revolution, has following statistics:
| ? | A | B | C | D | A |
| Xa | 0 | -a | 0 | a | 0 |
| Za | a+g | g | -a+g | g | a+g |
Deduce out the lopcus function curve of motion as shown in Figure 4,
2. hypothesis wheel clickwise, has following statistics:
| ? | A | D | C | B | A |
| Xa | 0 | -a | 0 | a | 0 |
| Za | a+g | g | -a+g | g | a+g |
And the lopcus function curve of deducing out motion as shown in Figure 5.
By above force analysis and obtain the mass data in actual test, carry out sampling analysis, after Fuzzy Processing, can draw, taking Z axis as reference, any time that can be in rotation process, judge the hand of rotation of cw or conter clockwise, judge sine or cosine curve.Left and right tire on vehicle body, travels in the same way, and the X-axis of sensor is mutually anti-phase, and Z axis is constant, and can regard one is clickwise, and one is left-hand revolution, therefore can judge left and right tire, concrete judgement flow process as shown in Figure 6.Front and back position can be by receiving end RSSI(signal strength) judge, concrete judgement flow process is as shown in Figure 7.
