The first embodiment is as follows:
referring to fig. 1, an overspeed identification method provided in an embodiment of the present application is described below, where the overspeed identification method in the embodiment of the present application includes:
s101, vehicle information acquired by a tire pressure sensor is acquired in a wireless communication mode;
most of the current vehicles are equipped with a Tire Pressure Monitoring System (TPMS). The tire pressure sensor in the tire pressure monitoring system is usually disposed at a hub of a vehicle tire, and the tire pressure sensor may be formed by combining one or more of a pressure sensor, an acceleration sensor, a temperature sensor, and the like.
The vehicle information collected by the tire pressure sensor may include a radial acceleration and an angular velocity of the tire pressure sensor. Because the tire pressure sensor carries out data interaction to the outside in a wireless communication mode, when the terminal equipment needs to calculate the instantaneous speed of the vehicle, the terminal equipment can carry out data interaction with the tire pressure sensor in a wireless communication mode to acquire the vehicle information acquired by the tire pressure sensor.
The wireless communication mode may be set according to actual conditions, for example, the wireless communication mode may include one or more of a cellular network communication mode, a bluetooth communication mode, a wifi communication mode, and a radio frequency communication mode.
S102, determining the instantaneous speed of the vehicle according to the vehicle information
After the terminal device acquires the vehicle information, the instantaneous speed of the vehicle can be calculated according to the vehicle information.
The vehicle information may include a radial acceleration and an angular velocity, after the terminal device acquires the radial acceleration and the angular velocity, the terminal device may calculate the translational acceleration of the vehicle according to the radial acceleration and the angular velocity, and the specific calculation process is as follows:
as shown in fig. 2, a rectangular coordinate system XOY is established with the 0-position origin of the axis of the tire, the radius of the dotted line circle is R, which represents the hub of the tire, the tire pressure sensor is mounted on the hub (i.e., at the black point on the dotted line circle), and the radius of the solid line circle is R, which represents the outer contour of the tire.
Analyzing the acceleration of the tire pressure sensor to obtain the radial acceleration a detected by the tire pressure sensorrFrom an acceleration a1Acceleration a2And acceleration a3The composition is as follows:
ar＝a1+a2+a3(1)
wherein the acceleration a1Is the acceleration component of the gravity acceleration g on a radial line, the radial line is a straight line where the tire pressure sensor and the axis of the tire are located, and the acceleration a takes the direction of the tire pressure sensor pointing to the axis of the tire as the positive direction1Can be expressed as:
a1＝g*cosθ (2)
wherein the gravity acceleration g can be 9.8m/s2Or, the corresponding value can be taken according to the region. Theta is gravity acceleration and radial acceleration arThe included angle of (a).
Acceleration a2Is the translational acceleration a of the vehicle4The component of the acceleration on the radial line, the acceleration a2Can be expressed as:
a2＝a4*cosα (3)
wherein α is translation acceleration a4Angle to radial acceleration.
Acceleration a3For the centrifugal acceleration received by the tire pressure sensor, a3 may be expressed as:
a3＝ω2r (4)
where ω is an angular velocity, and r is a distance from the mounting position of the tire pressure sensor to the axis of the tire.
Simultaneous formula (1), formula (2), formula (3) and formula (4), the translational acceleration a of the vehicle4Can be expressed as:
after the terminal device calculates the translational acceleration corresponding to the current time, the instantaneous speed of the vehicle can be calculated according to the initial speed of the vehicle and the translational acceleration corresponding to the current time.
In some possible implementations, the initial speed may be an instantaneous speed obtained by previous calculation, and since the acquisition frequency of the tire pressure sensor is high, a preset time interval between two adjacent data acquisition operations is short, and therefore, within the preset time interval, the movement mode of the vehicle may be considered as uniform acceleration movement.
At this time, the terminal device may multiply the translational acceleration by a preset time interval to obtain a velocity increment, where the preset time interval is a time interval between the time corresponding to the initial velocity and the current time. The higher the acquisition frequency of the tire pressure sensor, the shorter the duration of the preset time interval.
After the terminal device calculates the speed increment, the initial speed may be added to the speed increment to obtain the instantaneous speed corresponding to the current time.
It is understood that the instantaneous speed corresponding to the current time is also the initial speed at the next time the instantaneous speed is calculated.
S103, acquiring the position information of the vehicle, and determining the speed limit speed according to the position information;
in identifying an overspeed event, in addition to the instantaneous speed of the vehicle, the speed limit of the area in which the vehicle is located needs to be obtained.
For example, when the vehicle is traveling on a road in an urban area, the speed limit may be 30 km/h; when the vehicle is traveling on a national road, the speed limit may be 80 km/h; when the vehicle is traveling on a highway, the speed limit may be 120 km/h.
Therefore, it is necessary to acquire the position information of the vehicle and then determine the speed limit speed of the vehicle on the road section according to the position information. The manner of acquiring the position information of the vehicle may be selected according to actual conditions. For example, a Global Positioning System (GPS) may be selected to determine the location information of the vehicle; or the position information of the vehicle can be determined through the Beidou positioning system; alternatively, the position information of the vehicle may be determined in other ways.
And S104, if the instantaneous speed is greater than the speed limit speed, determining that an overspeed event occurs.
After the terminal device obtains the instantaneous speed of the vehicle at the current time and the speed-limiting speed of the road section where the vehicle is located, whether the vehicle has an overspeed event or not can be judged.
And if the instantaneous speed of the vehicle at the current time is greater than the speed-limiting speed of the road section where the vehicle is located, judging that an overspeed event occurs.
And if the instantaneous speed of the vehicle at the current time is less than or equal to the speed-limiting speed of the road section where the vehicle is located, judging that the non-overspeed event occurs.
For example, if the instantaneous speed of the vehicle at the current time is 93 kilometers per hour, and the speed limit speed of the road section where the vehicle is currently located is 80 kilometers per hour, it may be determined that the vehicle has an overspeed event at the current time. If the instantaneous speed of the vehicle at the current time is 93 kilometers per hour, and the speed-limiting speed of the road section where the vehicle is located is 120 kilometers per hour, the vehicle can be judged to have a non-overspeed event at the current time.
Through the mode, the identification of the overspeed event can be realized on the basis of not increasing the hardware cost. And after the overspeed event and the non-overspeed event are detected, punishment can be carried out on the driver or the privilege can be given by combining with certain punishment terms and privilege terms, so that the driving behavior of the driver is restrained, and unnecessary wear of the vehicle is reduced.
After identifying the overspeed event, the terminal device may send overspeed information to the first block-link-point device to instruct the first block-link-point device to perform a winding operation on the overspeed information, and register the overspeed information in the block chain. The speeding information may include one or more of a speeding event, an instantaneous speed, location information, and a speed limit speed.
The block chain is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace retaining in the whole process, traceability, collective maintenance, openness and transparency and the like. The blockchain may cryptographically generate associated data blocks, each of which contains information to be recorded, by which the validity of the information in the data block can be verified and a next block generated.
The block chain is used for recording the overspeed information, so that the overspeed information of a driver can be prevented from being destroyed or tampered maliciously by others, and the authenticity of the overspeed information is ensured, so that evidence collection and rechecking can be carried out when disputes occur later.
In some possible implementation manners, when the user suspects about the overspeed event and wishes to obtain evidence for rechecking, the terminal device may be operated to trigger the information viewing request. When the terminal device obtains the information viewing request, the terminal device may send the information viewing request to the second block link point device to indicate the overspeed information corresponding to the information viewing request, which is queried and returned by the second block link point device.
And after the terminal equipment receives overspeed information corresponding to the information checking request returned by the second block link point equipment, displaying the overspeed information to a user so that the user can verify whether an overspeed event occurs according to the overspeed information.
In addition, after recognizing the non-overspeed event, the terminal device may also send non-overspeed information to the third blockchain node device to instruct the third blockchain node device to perform a winding operation on the non-overspeed information, and register the non-overspeed information in the blockchain. The non-overspeed information can include one or more of a non-overspeed event, an instantaneous speed, location information, and a speed limit speed.
The non-overspeed information can be applied to downstream functions such as analysis of driving behavior habits of users, calculation of vehicle ages and the like.
It will be appreciated that in a block chain, the individual block link point devices are arranged in a distributed manner, and each block link point device has the same status and function. Therefore, the first block link point device, the second block link point device, and the third block link node device may be the same block link point device, or the first block link point device, the second block link point device, and the third block link node device may be two or more different block link point devices. That is, the user can register overspeed information, non-overspeed information and query overspeed information through the same block link point device; alternatively, the user may register the overspeed information, the non-overspeed information, and the inquiry overspeed information through a plurality of block link point devices.
In some possible implementations, after the overspeed event is determined to occur, the terminal device may further perform a preset overspeed warning operation so as to remind the driver that the driving speed should be slowed down.
The preset overspeed warning operation can be set according to actual conditions. The preset overspeed warning operation may include one or more of text prompt operation, light prompt operation, sound prompt operation, and other warning operations.
For example, when the terminal device detects that an overspeed event occurs, a red light can be flashed, and a voice prompt "you overspeed and please slow down.
In the overspeed identification method provided by the first embodiment of the present application, the terminal device may calculate the instantaneous speed of the vehicle through the vehicle information collected by the tire pressure sensor. Meanwhile, the terminal equipment can also determine the speed-limiting speed of the current road section according to the position information of the vehicle, and integrates the instantaneous speed and the speed-limiting speed of the vehicle to identify whether the vehicle is overspeed or not.
The tire pressure sensor is usually arranged at a tire hub of a vehicle, and the tire pressure sensor performs data interaction to the outside in a wireless communication mode. Therefore, the terminal equipment can perform data interaction with the tire pressure sensor in a wireless communication mode to obtain the vehicle information acquired by the tire pressure sensor, and in the data acquisition process, the terminal equipment does not need to be additionally provided with a special OBD connecting line, so that the data acquisition mode is more flexible, the limitation of an application scene is reduced, and the problems that the data acquisition mode required by the existing overspeed identification scheme is not flexible and the application scene is greatly limited are solved.
And when the terminal equipment detects an overspeed event or a non-overspeed event, the overspeed information or the non-overspeed information can be sent to the block chain system for uplink operation, the safety of the overspeed information and the non-overspeed information is improved according to the non-tampering characteristic of the block chain, the overspeed information or the non-overspeed information is prevented from being maliciously tampered by others, and the truth and the reliability of the overspeed information and the non-overspeed information are ensured.
In addition, after an overspeed event is detected, the terminal equipment can execute preset overspeed warning operation in time to remind a driver to slow down the speed of a vehicle, so that the possibility of traffic accidents is reduced.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
