Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The wheel position positioning method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein a plurality of sensors 102 communicate with a receiver 104 over a network. The data storage system may store data that the receiver 104 needs to process. The data storage system may be placed on the cloud or other network server. The receiver 104 may provide the sensor 102 with an environment for wheel location positioning. When the wheel is in a traveling state, the receiver 104 acquires the first position of the plurality of sensors 102 and acquires the maximum wireless signal transmitted by each of the plurality of directional antennas within a preset time. Then, the receiver 104 determines a second position of the sensor 102 corresponding to each of the maximum wireless signals based on the transmission directions of the maximum wireless signals and the actual strengths of the maximum wireless signals. Further, the receiver 104 determines the wheel on which each sensor 102 is located based on the second positions of the plurality of sensors 102 and the first positions of the plurality of sensors 102.
The wheel position positioning method provided by the embodiment of the application can be applied to a system comprising a receiver and a sensor, and is realized through interaction of the receiver and the sensor.
In one embodiment, as shown in fig. 2, a wheel location method is provided, which is illustrated by applying the method to a system implementation including a receiver and a sensor, and includes the following steps 202 to 206.
In the present embodiment, a Directional antenna (Directional antenna) refers to an antenna that is particularly strong in transmitting and receiving electromagnetic waves in one or more specific directions, and is null or extremely small in transmitting and receiving electromagnetic waves in other directions. The directional transmitting antenna can increase the effective utilization rate of the radiation power, enhance the signal strength and increase the anti-interference capability.
In this embodiment, the sensor may continuously transmit a wireless signal for a time T in a fixed direction through the directional antenna when the wheel is in a traveling state.
In this embodiment, the receiver may receive, within a preset time, a plurality of wireless signals transmitted by each directional antenna, and then, for each directional antenna, acquire, as the maximum wireless signal transmitted by the directional antenna, a wireless signal with the maximum signal strength among the plurality of wireless signals transmitted by each directional antenna.
In another embodiment, the receiver may continue to receive multiple wireless signals transmitted by each directional antenna until the sensor stops transmitting wireless signals. And then, aiming at each directional antenna, acquiring a wireless signal with the maximum signal strength in a plurality of wireless signals sent by each directional antenna as the maximum wireless signal sent by the directional antenna.
In this embodiment, the first position may be referred to a vehicle head driving direction, and the wheels parallel to the vehicle head driving direction are sequentially a first row of wheels, a second row of wheels, a third row of wheels, 823082308230, and an mth row of wheels, where M is a positive integer.
And step 204, determining a second position of the sensor corresponding to each maximum wireless signal based on the transmission directions of the maximum wireless signals and the actual strength of the maximum wireless signals.
In this embodiment, based on the sending directions of the multiple maximum wireless signals, the reference strength of the signal strength of the maximum wireless signal corresponding to the directional antenna at the different second positions may be determined;
the second position of the sensor corresponding to each maximum wireless signal received by the receiver can be determined based on the reference strength of the signal strength of the maximum wireless signal corresponding to the directional antenna at different second positions and the actual strength of the plurality of maximum wireless signals.
In this embodiment, the second position may be a first row of wheels, a second row of wheels, a third row of wheels, a fourth row of wheels, a sixth row of wheels, a seventh row of wheels, a tenth row of wheels, a ninth row of wheels, and a tenth row of wheels, where N is a positive integer.
And step 206, determining the wheel where each sensor is located based on the second positions of the plurality of sensors and the first positions of the plurality of sensors.
In this embodiment, the receiver may determine the wheel on which each sensor is located based on the number of columns and rows on which the sensors are located.
In the wheel position positioning method, when a wheel is in a running state, first positions of a plurality of sensors are obtained, and a maximum wireless signal sent by each directional antenna in a plurality of directional antennas is obtained within a preset time; then, based on the sending directions of the maximum wireless signals and the actual strength of the maximum wireless signals, determining a second position of the sensor corresponding to each maximum wireless signal; and finally, determining the wheel where each sensor is located based on the second positions of the plurality of sensors and the first positions of the plurality of sensors. This application is through directional antenna for every sensor all has specific directive, and it is comparable to realize that the receiver receives the signal of each sensor, can improve the accuracy of wheel position location.
In some embodiments, acquiring a first position of the plurality of sensors while the wheel is in the travel state may include: acquiring the motion state of the wheel based on the acceleration of the wheel; the motion state of the wheel includes: stopping or advancing; when the wheel is in a traveling state, a first position of the plurality of sensors is acquired based on the acceleration sensor.
In the present embodiment, the sensor reads its own acceleration, and determines the traveling state of the wheel based on the own acceleration. When the acceleration of the sensor itself is not equal to 0, the wheel is in a traveling state.
In this embodiment, when the wheel is in a traveling state, the first position of the sensor may be resolved based on a multi-axis acceleration sensor among the TPMS sensors. For example, when the vehicle is a four-wheel vehicle, the first position of the sensor may be determined based on a two-axis sensor, a value of an X-axis directed in a forward direction of the vehicle and a value of a Z-axis directed in a direction of an axle, respectively.
In this embodiment, when the vehicle traveling direction is the vehicle head direction and each wheel is provided with a sensor, the wheels parallel to the vehicle head traveling direction are sequentially a first row of wheels and a second row of wheels from left to right with reference to the vehicle head traveling direction. As shown in fig. 3, the axial position of the acceleration is different for the sensor acceleration. For example, as shown in fig. 4, we assume that the first row of wheels is X1 and the second row of wheels is X2; when the two wheels roll, the acceleration of the Z Axis is a constant sine wave (Z Axis), the acceleration curve (Left X) of the sensor of X1 is advanced by 90 degrees relative to the sine wave, and the acceleration curve (Right X) of the sensor of X2 is lagged by 90 degrees. Thus, based on the acceleration of the dual-axis sensor, the first position at which the sensor is located may be determined.
In some embodiments, acquiring the maximum wireless signal transmitted by each of the plurality of directional antennas within the preset time may include: acquiring the sending direction of each directional antenna for sending wireless signals; for each directional antenna, receiving a plurality of wireless signals sent by the directional antenna within preset time based on the sending direction corresponding to the directional antenna, and determining the maximum wireless signal corresponding to the directional antenna from the plurality of wireless signals; the maximum wireless signal corresponding to the directional antenna is a wireless signal with the maximum signal strength in the plurality of wireless signals corresponding to the directional antenna.
In this embodiment, the sensor is via a directional antenna. The wireless signal with a specific direction is transmitted, and the receiver can distinguish the wireless signals transmitted by different directional antennas based on a plurality of received signals. And acquiring a wireless signal with the maximum signal strength in a plurality of wireless signals corresponding to each directional antenna as the maximum wireless signal corresponding to the directional antenna aiming at the plurality of wireless signals transmitted by each directional antenna.
In this embodiment, when the sensors are all pointed at the receiver with the strongest transmission, the transmission power is comparable, facilitating subsequent strength comparisons of the largest wireless signals.
In some embodiments, obtaining the transmission direction of each directional antenna for transmitting the wireless signal may include: and determining the corresponding sending direction of the directional antenna based on the preset position of the directional antenna on the wheel.
In this embodiment, receiving, within a preset time, a plurality of wireless signals transmitted by a directional antenna based on a transmission direction corresponding to the directional antenna may include: and receiving a plurality of wireless signals transmitted when the directional antenna is at a preset position on the wheel within a preset time based on the corresponding transmitting direction of the directional antenna.
In this embodiment, the sensor can determine and calculate its position (for example, on the top or bottom of the wheel, or at a specific position) through its acceleration, and when the sensor reaches a preset position on the wheel, the sensor controls the directional antenna to transmit a wireless signal.
In this embodiment, based on the position where the directional antenna transmits the wireless signal and the transmission direction of the directional antenna, the relative direction of the wireless signal transmitted by the directional antenna with respect to the receiver when the sensor reaches the preset position on the wheel can be obtained. The receiver can distinguish between the wireless signals transmitted by different directional antennas based on the relative directions. Further, for a plurality of wireless signals transmitted by each directional antenna, a wireless signal with the maximum signal strength in the plurality of wireless signals corresponding to the directional antenna is obtained as the maximum wireless signal corresponding to the directional antenna.
In some embodiments, determining the second position of the sensor corresponding to each of the maximum wireless signals based on the transmission direction of the plurality of maximum wireless signals and the actual strength of the plurality of maximum wireless signals may include: determining relative directions of the plurality of maximum wireless signals and the receiver based on the transmission directions of the plurality of maximum wireless signals; determining the reference strength of the maximum wireless signals transmitted by the plurality of sensors based on the relative direction; and determining a second position of the sensor corresponding to each maximum wireless signal based on the actual strength and the reference strength of the plurality of maximum wireless signals.
In this embodiment, the transmission direction of the directional antenna on each sensor is uniform because the sensor cannot know at the time of production that each sensor is mounted on the wheel. For example, assuming that a four-wheeled vehicle is equipped with directional antennas each transmitting a wireless signal in the direction of the rear of the vehicle, and a receiver is installed at the rear of the vehicle, the reference strength between the signal strength (e.g., strength a, strength B) of the maximum wireless signal transmitted to the receiver by the directional antenna on the row of wheels near the front of the vehicle and the signal strength (e.g., strength C, strength D) of the maximum wireless signal transmitted to the receiver by the directional antenna on the row of wheels near the rear of the vehicle may be: the intensity A is approximately equal to the intensity B and the intensity C is approximately equal to the intensity D.
In one illustrative example, intensity A may also be equal to intensity B and intensity C may also be equal to intensity D.
In this embodiment, the receiver may determine the second position of the wheel where the sensor corresponding to each maximum wireless signal is located based on the transmission direction of the maximum wireless signal and the actual strength of the plurality of maximum wireless signals.
In some embodiments, determining the second position of the sensor corresponding to each of the maximum wireless signals based on the transmission direction of the plurality of maximum wireless signals and the actual strength of the plurality of maximum wireless signals may include: determining relative directions of the plurality of maximum wireless signals and the receiver based on the transmission directions of the plurality of maximum wireless signals; determining the reference strength of the maximum wireless signals transmitted by the plurality of sensors based on the relative direction; sorting the maximum wireless signals in an ascending order or a descending order according to the actual strength of the maximum wireless signals, and grouping the sorted maximum wireless signals; the wireless communication system comprises a plurality of wireless communication units, a signal processing unit and a signal processing unit, wherein a plurality of maximum wireless signals with the same signal intensity form a group; and determining the second position of the sensor corresponding to each group of the maximum wireless signals based on the actual strength of the maximum wireless signals in each group and the reference strength of the maximum wireless signals.
In this embodiment, the receiver may sort the maximum wireless signals in ascending or descending order according to the actual strength of the maximum wireless signals, and perform grouping based on the signal strength of the sorted maximum wireless signals.
In this embodiment, the intensities of the maximum wireless signals in the same group may not be equal to each other, but the signal intensity error is within the preset error threshold.
In an exemplary embodiment, the present solution is applied to a six-wheeled truck, and the sensor continuously transmits a wireless signal for T times in a fixed direction through the directional antenna when the wheels are in a traveling state. The receiver receives a plurality of wireless signals transmitted by each directional antenna until the sensor stops transmitting the wireless signals. Then, the receiver acquires, for each directional antenna, a wireless signal with the maximum signal strength among the plurality of wireless signals transmitted by each directional antenna as the maximum wireless signal transmitted by the directional antenna. The maximum wireless signals transmitted by the directional antennas are 1 (intensity a), 2 (intensity B), 3 (intensity C), 4 (intensity D), 5 (intensity E), and 6 (intensity F), and the intensity a = intensity E < intensity C ≈ intensity F < intensity B = intensity D.
In this embodiment, the first position is defined by taking the traveling direction of the vehicle head as a reference, and the wheels parallel to the traveling direction of the vehicle head are sequentially a first row of wheels and a second row of wheels from left to right. The second position is based on the traveling direction of the vehicle head (the vehicle head direction is taken as front), and the first row of wheels, the second row of wheels and the third row of wheels are arranged in sequence from near to far from the vehicle head direction.
In this embodiment, based on the transmission directions of the multiple maximum wireless signals, the reference strength of the signal strength of the maximum wireless signal corresponding to the directional antenna at the different second position may be determined. When the receiver is located at the rear of the vehicle, and the plurality of directional antennas transmit wireless signals in the direction of the rear of the vehicle, then the reference strength of the signal strength of the maximum wireless signal corresponding to the directional antenna at the different second position should be: the signal strength sent by the directional antenna on the third row of wheels is less than that sent by the directional antenna on the second row of wheels and less than that sent by the directional antenna on the first row of wheels. Since the actual strength of the signal strength of the plurality of largest wireless signals is: intensity a = intensity E < intensity C ≈ intensity F < intensity B = intensity D, then the second position of the maximum wireless signals 1, 5 is the third row of wheels, the second position of the maximum wireless signals 3, 6 is the second row of wheels, and the second position of the maximum wireless signals 2, 4 is the first row of wheels.
Finally, the wheel where each sensor is located is determined based on the second positions of the plurality of sensors and the first positions of the plurality of sensors.
It should be understood that, although the steps in the flowcharts related to the embodiments as described above are sequentially displayed as indicated by arrows, the steps are not necessarily performed sequentially as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
