Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The tire pressure monitoring method provided by the embodiment of the application can be applied to the internet of vehicles (TELEMATICS BOX, tbox) in the target vehicle. For example, referring to fig. 1, fig. 1 provides an application environment diagram of a tire pressure monitoring method. The bluetooth sensor 102 may send the tire pressure monitoring data to Tbox through the bluetooth function, tbox wakes up the tire pressure monitoring process when the speed of the target vehicle is greater than a set threshold and when the tire pressure monitoring data sent by the bluetooth sensor on the target vehicle is received within a preset time period; and through the tire pressure monitoring process, the tire pressure monitoring result of the target vehicle is determined according to the tire pressure monitoring data, and then the tire pressure condition can be fed back to the user based on the tire pressure monitoring result, so that the user can take corresponding measures in time, and the safety problem of the target vehicle is avoided.
When the tire pressure condition is fed back to the user, the tire pressure monitoring data and the tire pressure monitoring result CAN be packaged according to the communication protocol among the controllers in the vehicle to form a serial communication protocol (Controller Area Network, CAN) data packet, and the serial communication protocol (Controller Area Network, CAN) data packet is sent to the corresponding CAN bus of the vehicle through the network topology structure of the whole vehicle, so that the tire pressure monitoring condition is displayed on a display interface, and the tire pressure monitoring condition is fed back to the user.
In one embodiment, as shown in fig. 2, a tire pressure monitoring method is provided, and the tire pressure monitoring method is applied to Tbox in fig. 1 for illustration, and includes the following steps:
S201, if the tire pressure monitoring data sent by the Bluetooth sensor on the target vehicle is received within the preset time period under the condition that the speed of the target vehicle is greater than the set threshold value, the tire pressure monitoring process is awakened.
Optionally, the target vehicle may be understood as a vehicle needing to perform tire pressure monitoring, where the tire pressure of the vehicle needs to be kept within a safe tire pressure range, so that the tire pressure of the target vehicle needs to be monitored, so that when the tire pressure of the target vehicle is abnormal, feedback is timely given to a user, so that the user can timely make corresponding measures to avoid a problem. The method and the device can judge whether the speed of the target vehicle is greater than a set threshold value or not, and judge whether the acceleration data of the target vehicle is greater than the set threshold value or not.
Exemplary tire pressure monitoring data includes, but is not limited to, tire pressure, tire temperature, bluetooth sensor power, and the like.
It should be noted that, the tire pressure of the target vehicle may be monitored during the running process of the target vehicle, and the tire pressure data of the target vehicle does not need to be monitored when the target vehicle is in a stationary state. Thus, the tire pressure of the target vehicle may be monitored if the vehicle speed data of the target vehicle is greater than a set threshold value, which is used to characterize that the target vehicle is in a stationary state, for example, the set threshold value may be set to 0. If the tire pressure monitoring data sent by the Bluetooth sensor on the target vehicle is received within the preset time period under the condition that the speed of the target vehicle is greater than the set threshold value, the tire pressure monitoring process can be awakened. The preset duration is used for reflecting the time delay of the data sent by the bluetooth sensor, and can be set according to actual requirements or experience data, for example, the preset duration can be set to 15 seconds.
It can be understood that when the target vehicle is in a driving state and the tire pressure monitoring data sent by the bluetooth sensor on the target vehicle is received within the time delay time of the bluetooth sensor, the tire pressure monitoring process can be awakened to perform tire pressure monitoring.
The Bluetooth sensor has a unidirectional data transmission function; it will be appreciated that the bluetooth sensor is not involved in receiving Tbox the transmitted data, i.e., is not involved in a complex data transfer protocol, thereby reducing the power consumption of the bluetooth sensor.
S202, determining the tire pressure monitoring result of the target vehicle according to the tire pressure monitoring data through the tire pressure monitoring process.
Alternatively, through the tire pressure monitoring process, it may be determined whether the tire pressure monitoring data is within a safe range based on the tire pressure monitoring data to determine the tire pressure monitoring result of the target vehicle. For example, if the tire pressure monitoring data is within the safety range, the tire pressure monitoring result of the target vehicle is determined to be normal, and if the tire pressure monitoring data is not within the safety range, the tire pressure monitoring result of the target vehicle is determined to be abnormal.
According to the tire pressure monitoring method, the Tbox with the Bluetooth function is used for receiving the tire pressure detection data sent by the Bluetooth sensor, and a Bluetooth receiver is not required to be arranged independently for receiving the tire pressure detection data sent by the Bluetooth sensor, so that the hardware cost for realizing the tire pressure monitoring function is reduced; specifically, if the tire pressure monitoring data sent by the Bluetooth sensor on the target vehicle is received within a preset time period under the condition that the speed of the target vehicle is greater than a set threshold value, the tire pressure monitoring process is awakened; and through the tire pressure monitoring process, the tire pressure monitoring result of the target vehicle is determined according to the tire pressure monitoring data, so that the power consumption of Tbox can be reduced; and the Bluetooth sensor has a unidirectional data transmission function, does not relate to a complex communication protocol, and further reduces the power consumption of the Bluetooth sensor.
In some optional implementations, the tire pressure monitoring data may include tire pressure monitoring data of each tire in the target vehicle, so that in a process of determining a tire pressure monitoring result of the target vehicle according to the tire pressure monitoring data, whether abnormal tire pressure monitoring data which is not in a preset numerical range exists in each tire pressure monitoring data or not may be determined, and if abnormal tire pressure monitoring data which is not in the preset numerical range exists in each tire pressure monitoring data, the tire pressure monitoring result of the target vehicle is determined to be abnormal in tire pressure. For example, if the target vehicle has 4 tires, the tire pressure monitoring data includes tire pressure monitoring data of the 4 tires, and if at least 1 abnormal tire pressure monitoring data which is not within a preset numerical range exists in each tire pressure monitoring data, the tire pressure monitoring result of the target vehicle is determined to be abnormal tire pressure.
In the embodiment of the application, as long as the abnormal tire pressure monitoring data which is not in the preset numerical range exists, the tire pressure monitoring result of the target vehicle can be considered as abnormal tire pressure, and the abnormal tire pressure monitoring result of the tire pressure can be fed back to the user, so that the user can adjust the tire pressure in time according to the abnormal tire pressure monitoring result of the tire pressure, and safety accidents are avoided.
In some optional implementation manners, if the tire pressure monitoring result of the target vehicle is determined to be abnormal, the abnormal tire can be further determined so as to quickly locate the tire with abnormal tire pressure, and efficiency of removing the abnormal tire pressure is improved.
Specifically, referring to fig. 3, fig. 3 provides a schematic flow chart for determining an abnormal tire, which specifically includes the following steps:
S301, obtaining a tire identifier corresponding to the abnormal tire pressure monitoring data.
For example, a data format of the tire pressure monitoring data may be preset, for example, the tire pressure monitoring data may be set to include a corresponding tire identifier, where the tire identifier is used to distinguish each tire, and for example, the tire identifier may be a tire number. For example, the corresponding tire identification may be extracted from the abnormal tire pressure monitoring data.
S302, determining a target tire according to the tire identification.
It is understood that the correspondence between the tire identifiers and the tires may be preset, and in the case that the tire identifiers are obtained, the target tire may be determined according to the tire identifiers and the correspondence between the tire identifiers and the tires.
S303, outputting abnormal tire pressure warning information for the target tire.
Outputting alarm information of abnormal tire pressure of the tire pressure aiming at the target tire pressure under the condition that the abnormality exists in the target tire pressure is determined; for example, abnormal warning information of too high or too low tire pressure may be output. The abnormal alarm information may have various expression forms, for example, a voice broadcasting mode, a frame playing reminding mode, or a combination of various modes, and the display mode of the abnormal alarm information is not specifically limited.
According to the embodiment of the application, the tire identification in the abnormal tire pressure monitoring data can be extracted by setting the tire identification, the tire with abnormal tire pressure can be determined, the tire with abnormal tire pressure can be rapidly positioned, and the efficiency of relieving the abnormal tire pressure can be further improved.
In some alternative implementations, referring to fig. 4, fig. 4 provides a schematic flow chart for obtaining a tire identifier, which specifically includes the following steps:
s401, acquiring a Media Access Control (MAC) address and/or a sensor identifier of a Bluetooth sensor for transmitting abnormal tire pressure monitoring data.
For example, when the data format of the anomaly monitoring data is set, the data format of the anomaly monitoring data may be set to include a media access Control (MEDIA ACCESS Control, MAC) address and/or a sensor identifier of the bluetooth sensor, where the MAC address of the bluetooth sensor is also referred to as a physical address, and may be used to determine an address of the network device location, that is, an address used to determine the location of the bluetooth sensor; the sensor identification is used to distinguish between different bluetooth sensors.
For example, the MAC address and/or the sensor identification of the bluetooth sensor may be extracted from the anomaly monitoring data after the anomaly monitoring data is acquired. For example, only the MAC address of the bluetooth sensor may be extracted, only the sensor identification may be extracted, and the MAC address of the bluetooth sensor and the sensor identification may be extracted.
S402, determining the tire identification corresponding to the abnormal tire pressure monitoring data according to the MAC address and/or the sensor identification.
The corresponding relation between the MAC address and each tire identifier can be preset, so that the tire identifier corresponding to the abnormal tire pressure monitoring data is determined based on the corresponding relation between the MAC address and each tire identifier and the corresponding relation between the MAC address and each tire identifier; similarly, the corresponding relation between the sensor identifier and each tire identifier may be preset, so that the tire identifier corresponding to the abnormal tire pressure monitoring data may be determined according to the sensor identifier and the corresponding relation between the sensor identifier and each tire.
The embodiment of the application provides an implementation mode for acquiring the tire identifier, which can further determine the tire identifier corresponding to the Bluetooth sensor by acquiring the MAC address and/or the sensor identifier of the Bluetooth sensor so as to quickly locate the tire with abnormal tire pressure.
In some optional implementations, if the speed of the target vehicle is greater than the set threshold, it may also be monitored whether the bluetooth sensor is able to normally send the tire pressure monitoring data to Tbox, thereby determining whether the bluetooth sensor is abnormal.
For example, it may be determined whether the tire pressure monitoring data sent by the bluetooth sensor may be received within a preset period of time, and if the tire pressure monitoring data sent by the bluetooth sensor is not received within the preset period of time, abnormal alarm information for the bluetooth sensor is output. The abnormal alarm information may have various expression forms, for example, a voice broadcasting mode, a frame playing reminding mode, or a combination of various modes, and the display mode of the abnormal alarm information is not specifically limited.
In the embodiment of the application, whether the Bluetooth sensor is abnormal or not is determined by judging whether the tire pressure monitoring data sent by the Bluetooth sensor can be received within the preset time length; and when the Bluetooth sensor is determined to be abnormal, alarm information of the abnormality of the Bluetooth sensor is timely sent, so that a user can take measures conveniently, and safety accidents caused by untimely monitoring of tire pressure monitoring data are further avoided.
Further, the target vehicle may be configured with a plurality of bluetooth sensors, and each bluetooth sensor is configured to monitor the tire pressure of one tire, and on the basis of this, referring to fig. 5, fig. 5 provides a flow chart for outputting abnormal alarm information, which specifically includes the following steps:
S501, if only the tire pressure monitoring data sent by the first Bluetooth sensor is received within the preset time period, determining whether the tire pressure monitoring data sent by the second Bluetooth sensor is received within the prolonged time period of the preset time period.
It should be noted that, the bluetooth sensor may have a fault or be lost, so that whether the bluetooth sensor is abnormal or not may be determined, and alarm information of the abnormality of the bluetooth sensor may be output when the bluetooth sensor is abnormal.
The tire pressure monitoring data sent by the bluetooth sensor may be determined whether to accept the tire pressure monitoring data sent by the bluetooth sensor within a set period of time, where the set period of time is used to characterize a transmission delay of the bluetooth sensor, and if the bluetooth sensor is in a normal state within the set period of time, tbox may receive the tire pressure monitoring data sent by the bluetooth sensor. However, when the bluetooth sensor transmits the tire pressure monitoring data, the bluetooth sensor may be affected by the network signal, so that an extended period of time may be set to exclude the influence of the network signal on the transmission of the tire pressure monitoring data by the bluetooth sensor.
Specifically, whether the tire pressure monitoring data sent by the Bluetooth sensor can be received within a preset time period can be judged, and if the tire pressure monitoring data of the Bluetooth sensor can be received, the Bluetooth sensor which can receive the tire pressure monitoring data is used as a first Bluetooth sensor. If only the tire pressure monitoring data sent by the first Bluetooth sensor is received within the preset time period, determining whether the tire pressure monitoring data sent by the second Bluetooth sensor is received within the preset time period, wherein the second Bluetooth sensor is a Bluetooth sensor except the first Bluetooth sensor in the plurality of Bluetooth sensors, namely the second Bluetooth sensor is a Bluetooth sensor which fails to receive the tire pressure monitoring data within the preset time period; the extension time period may be set according to actual conditions, or may be set according to empirical data, for example, may be set to 5 minutes.
It can be appreciated that if the second sensor is affected by the network signal within the preset duration, the tire pressure monitoring data cannot be successfully sent to Tbox, the second sensor is not affected by the network signal all the time within the preset duration by setting the extension duration, and if the second sensor is in a normal state, the tire pressure monitoring data can be successfully sent to Tbox.
S502, if not, outputting abnormal alarm information aiming at the second Bluetooth sensor.
If only the tire pressure monitoring data sent by the first Bluetooth sensor is received within the preset time period, and the tire pressure monitoring data sent by the second Bluetooth sensor cannot be received within the preset time period, the second Bluetooth sensor is considered to be lost or to be faulty, and therefore abnormal alarm information aiming at the second Bluetooth sensor can be output.
In the embodiment of the application, whether the Bluetooth sensor is abnormal or not is determined by setting the preset time length and the prolonged time length, so that erroneous judgment of the abnormality of the Bluetooth sensor is avoided; and when the Bluetooth sensor is determined to be abnormal, alarm information of the abnormality of the Bluetooth sensor is timely sent, so that a user can take measures conveniently, and safety accidents caused by untimely monitoring of tire pressure monitoring data are further avoided.
In some alternative implementations, in the case that the speed of the target vehicle is less than or equal to the set threshold value, it represents that the target vehicle is not in a driving state, and thus tire pressure data monitoring is not needed, in which case the tire pressure monitoring process may be controlled to enter a sleep mode; and when the speed of the target vehicle is greater than the set threshold value and the tire pressure monitoring data sent by the Bluetooth sensor on the target vehicle is received within the preset time, waking up the tire pressure monitoring process. Thereby power consumption can be reduced.
Optionally, the bluetooth sensor may also perform a wake-up operation when the speed of the target vehicle is greater than a set threshold, and monitor tire pressure monitoring data of each tire of the target vehicle, and further send the tire pressure monitoring data to Tbox; and entering a sleep mode if the speed of the target vehicle is less than or equal to a set threshold; thereby reducing the power consumption of the bluetooth sensor.
In an exemplary embodiment of the present application, when the target vehicle detects that the tire pressure monitoring data is abnormal, there may be a situation that the tire pressure monitoring process is not yet processed yet, so after the tire pressure monitoring process is awakened, whether the abnormal tire pressure monitoring data stored last but not yet processed is first determined, if yes, the abnormal tire pressure monitoring data is processed, for example, alarm information of the abnormality of the tire pressure monitoring data is fed back to the user.
In some alternative implementations, referring to fig. 6, fig. 6 provides a schematic flow chart of another tire pressure monitoring method, specifically including the following steps:
s601, judging whether the speed of the target vehicle is greater than a set threshold, if so, executing S602-611, and if not, executing S612.
S602, judging whether tire pressure monitoring data sent by a Bluetooth sensor can be received within a preset time period, if so, executing S603-S609, and if not, executing S610.
S603, waking up the tire pressure monitoring process.
S604, judging whether abnormal tire pressure monitoring data which is not in a preset numerical range exists in each tire pressure monitoring data, if so, executing S605, and if not, executing S609.
S605 acquires a media access control MAC address and/or a sensor identification of a bluetooth sensor that transmits abnormal tire pressure monitoring data.
S606, determining the tire identification corresponding to the abnormal tire pressure monitoring data according to the MAC address and/or the sensor identification.
S607, determining the target tire according to the tire identification.
S608, the tire pressure abnormality warning information for the target tire is output.
S609, outputting a tire pressure monitoring result that the tire pressure monitoring data are normal.
And S610, judging whether the tire pressure monitoring data sent by the second Bluetooth sensor is received within the prolonged time of the preset time under the condition that the tire pressure monitoring data sent by the first Bluetooth sensor is received within the preset time, if so, executing S611, and if not, executing S609.
S611, abnormal alarm information for the second bluetooth sensor is output.
S612, controlling the tire pressure monitoring process to enter a sleep mode.
The specific processes of S601 to S612 may be referred to the description of the method embodiments, and the implementation principle and technical effects are similar, and are not repeated herein.
It should be understood that, although the steps in the flowcharts related to the embodiments described above are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows.

The implementation of the solution provided by the device is similar to that described in the above method, so the specific limitations of one or more embodiments of the tire pressure monitoring device provided below may be referred to above as limitations of the tire pressure monitoring method, and will not be repeated here.
