Nowadays, the vehicle-mounted positioning terminal has become a standard for automobiles, generally, in order to make the signal receiving and sending good, the GPS antenna of the vehicle-mounted positioning terminal needs to be upward, and the vehicle-mounted positioning terminal is required to be fixedly installed on the automobile and cannot be detached, dropped or powered off. However, the vehicle-mounted positioning terminal often falls off or is damaged due to jolting or artificial damage in the driving process, and huge loss can be caused if a vehicle owner cannot find that the vehicle-mounted positioning terminal is abnormal in time. Currently, in the prior art, physical keys or light sensation is mostly adopted to prevent the vehicle-mounted positioning terminal from being detached. The physical key is that when the positioning terminal uses gum or magnetic force to stick the positioner, a physical key is pressed for a long time, and when the positioner is detached or falls off, the physical key is released to trigger an alarm signal. The light sensation is prevented tearing open anti-drop also is the same reason, replaces physical button with light sensation sensor back opening, triggers alarm signal when detecting light from strong to weak or from weak to strong. The two schemes need to be provided with independent trigger modules (buttons or light senses), so that the volume of the vehicle-mounted positioning terminal is increased, and meanwhile, the hardware cost is increased. According to the embodiment of the invention, the abnormal state of the vehicle-mounted positioning terminal can be judged according to the three-axis azimuth angle and the voltage value by acquiring the three-axis azimuth angle acquired by the inertial sensor in the vehicle-mounted positioning terminal and the voltage value in the power supply circuit of the vehicle-mounted positioning terminal. The embodiment of the invention does not modify the existing product, and saves the hardware cost compared with the traditional method. In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, fig. 1 is a schematic flowchart of an abnormality detection method for a vehicle-mounted positioning terminal according to an embodiment of the present invention, where an execution subject of the method is a server, and the server executes the method according to steps S101 to S103, where the method includes: step S101 to step S103.
And S101, acquiring a gravity acceleration value acquired by an inertial sensor in the vehicle-mounted positioning terminal and a voltage value in an external power supply circuit of the vehicle-mounted positioning terminal.
The inertial sensor is an indispensable electronic component in the vehicle-mounted positioning terminal. In one embodiment of the invention, the inertial sensor is an acceleration sensor, for example, a G-sensor, and the acceleration sensor is used for acquiring the gravity acceleration value of the vehicle-mounted positioning terminal. If the acceleration sensor is an axial sensor, the gravity acceleration value in one direction can be measured only; if the acceleration sensor is a biaxial sensor, gravity acceleration values in two directions (X, Y) can be measured; if the acceleration sensor is a three-axis sensor, gravity in three directions (X, Y, Z) can be measuredAn acceleration value. For example, if the acceleration sensor is a three-axis sensor, the gravity acceleration values measured in (X, Y, Z)3 directions are Fx、Fy、Fz。
The method comprises the steps of obtaining a voltage value in an external power supply circuit of the vehicle-mounted positioning terminal, wherein the vehicle-mounted positioning terminal comprises a voltage value measuring device, such as a voltmeter. The voltage value of the two ends of the external power supply circuit of the vehicle-mounted positioning terminal can be measured through the voltmeter.
In the embodiment of the invention, the vehicle-mounted positioning terminal is connected with the server through the wireless transmission protocol, and starts to upload data after the connection is successful. And after receiving the data uploaded by the vehicle-mounted positioning terminal in real time, the server disassembles the uploaded data packet through a cutoff symbol specified in the equipment protocol to obtain a single data packet uploaded by the vehicle-mounted positioning terminal. The data packets uploaded by different devices are simply parsed into headers, trailers, and content using an extensible decoder. And then the object analyzed by the decoder is converted into a more detailed data object, such as a GPS positioning packet, an LBS positioning packet, an alarm packet, etc., through a converter. And then the data are put into different queues of the cache server, after new data are monitored in the queues, the data are processed, different types of data packets are stored in different queues, and the different types of data packets are processed by different processors, so that the multithreading effect is generated, and the processing speed is improved. And after the processing is finished, putting the obtained information such as the state of the vehicle-mounted positioning terminal into a queue, and after the number of the elements in the queue reaches a certain number, inserting the elements into a database in batches for storage.
And S102, calculating the inclination angle of the vehicle-mounted positioning terminal according to the gravity acceleration value.
In the embodiment of the invention, the inclination angle of the vehicle-mounted positioning terminal refers to the inclination angle of each axis of the gravity acceleration and the coordinate axis, when the vehicle-mounted positioning terminal is fixedly installed on an automobile, the gravity acceleration and the inclination angle of each axis of the coordinate axis are theoretically fixed, and the gravity acceleration and the acceleration sensing terminal are convenient to calculate when the vehicle-mounted positioning terminal falls off or is detachedThe inclination angle of each shaft of the device is 0 when the vehicle-mounted positioning terminal is fixedly arranged on the automobile, and when the vehicle-mounted positioning terminal is detached or falls off, the inclination angle of each shaft of the acceleration sensor and the inclination angle of each shaft of the coordinate axis of the acceleration sensor can be changed. By measuring the component of the gravity acceleration on the X axis, the Y axis or the Z axis of the acceleration sensor, the inclination angle of the gravity acceleration and the X axis, the Y axis or the Z axis can be calculated. If the acceleration sensor is an axis sensor, only the inclination angle between the gravity acceleration and the X axis can be measured; if the acceleration sensor is a two-axis sensor, the gravity acceleration and the inclination angles of the X axis and the Y axis can be respectively measured; if the acceleration sensor is a three-axis sensor, the gravity acceleration and the inclination angles of the X axis, the Y axis and the Z axis can be measured respectively. For example, if the acceleration sensor is a three-axis sensor, the measurement result of the three-axis sensor in the X-axis is Fx，Fx＝gsinθx. Wherein g is the acceleration of gravity, θxIs the included angle between the gravity acceleration and the X axis, and can obtain theta through calculationxIn the same way, theta can be measuredyAnd thetaz. In one embodiment of the invention, the three-axis sensor is used for respectively measuring the gravity acceleration and the inclination angles of the X axis, the Y axis and the Z axis, and the three-axis sensor can be used for carrying out all-dimensional measurement, so that the measurement precision is more accurate.
Step S103, judging whether the vehicle-mounted positioning terminal is in an abnormal state or not according to the inclination angle and the voltage value, and if the vehicle-mounted positioning terminal is in the abnormal state, sending different alarm signals to a preset terminal corresponding to different abnormal states.
After the inclination angles of the gravitational acceleration and the axes of the coordinate axis and the voltage value of the power supply circuit are obtained, whether the vehicle-mounted positioning terminal is in an abnormal state or not is judged according to the inclination angles and the voltage value, the abnormal state of the vehicle-mounted positioning terminal is specifically judged, and different alarm signals are sent to a preset terminal corresponding to different abnormal states. In an embodiment of the present invention, the abnormal state includes: removed, dropped, clipped, or low voltage.
As shown in fig. 2, step S103 of the embodiment of the present invention: and judging whether the vehicle-mounted positioning terminal is in an abnormal state or not according to the inclination angle and the voltage value, and if so, sending different alarm signals to a preset terminal corresponding to different abnormal states, specifically comprising steps S1031 to S1034.
And step S1031, if the inclination angle is larger than a preset angle value and the voltage value is 0, sending a removed alarm signal to the preset terminal, wherein the removed alarm signal is used for indicating that the current vehicle-mounted positioning terminal is in a removed abnormal state.
The embodiment of the invention is explained by taking a three-axis acceleration sensor as an example, and if the inclination angle of the gravity acceleration and any axis of a coordinate axis is greater than the preset angle value and the voltage value of the power supply circuit is 0, the vehicle-mounted positioning terminal can be judged to be detached. The preset angle value is not set to be too small or too large, so that the condition of misjudgment is prevented. For example, the preset angle value is 80 degrees, when the inclination angle between the gravitational acceleration and any axis of the coordinate axis is greater than 80 degrees, it can be preliminarily determined that the vehicle-mounted positioning terminal has fallen off, if the voltage value of the power supply voltage is 0, it is proved that the external power is disconnected, and in combination with the fact that the vehicle-mounted positioning terminal has been detached, a detached alarm signal is sent to the preset terminal, the detached alarm signal is used for indicating that the current vehicle-mounted positioning terminal is in an detached abnormal state, and the preset terminal is a vehicle owner mobile phone.
It should be understood that the vehicle-mounted positioning terminal comprises a built-in battery, and the external power is connected for reporting the position at high frequency and the like, so that the external power can be periodically communicated with the server after being disconnected.
Step S1032, if the inclination angle is 0 and the voltage value is larger than 0 and smaller than a preset voltage value, sending a low-voltage alarm signal to the preset terminal, wherein the low-voltage alarm signal is used for indicating that the current vehicle-mounted positioning terminal is in a low-voltage abnormal state.
If the inclination angle of the gravitational acceleration and any axis of the coordinate axis is 0, it is preliminarily stated that the vehicle-mounted positioning terminal does not fall off or is detached, and it should be understood that a certain inclination angle is caused by an error in an actual situation, so that in an actual use, a certain error range may be set, for example, 0 to 5 degrees, and 0 to 5 degrees may be considered as not falling off or being detached. The preset voltage value is used for judging whether the vehicle-mounted positioning terminal is subjected to wire cutting or in a low-voltage state, for example, if the vehicle-mounted positioning terminal can normally work when the voltage of an external power supply circuit of the vehicle-mounted positioning terminal is 11V-12V, the preset voltage value is set to be 11V. If the inclination angle of the gravity acceleration and any axis of the coordinate axis is 0 and the voltage value is greater than 0 and smaller than a preset voltage value, the vehicle-mounted positioning terminal is in a low-voltage abnormal state, and possibly a hardware problem of the vehicle-mounted positioning terminal or a problem of a vehicle power supply device, a low-voltage alarm signal is sent to the preset terminal and used for indicating that the current vehicle-mounted positioning terminal is in the low-voltage abnormal state.
Step S1033, if the inclination angle is larger than a preset angle value and the voltage value is larger than a preset voltage value, sending a falling alarm signal to a preset terminal, wherein the falling alarm signal is used for indicating that the current vehicle-mounted positioning terminal is in a falling abnormal state.
When the inclination angle of the gravitational acceleration and any axis of the coordinate axis is larger than a preset angle, the vehicle-mounted positioning terminal can be preliminarily judged to fall off, if the voltage value is larger than a preset voltage value and is kept in a normal range, the vehicle-mounted positioning terminal can be further judged to fall off and not be detached, a falling-off alarm signal is sent to the preset terminal, and the falling-off alarm signal is used for indicating that the current vehicle-mounted positioning terminal is in a falling-off abnormal state.
Step S1034, if the inclination angle is 0 and the voltage value is 0, sending a cut line alarm signal to a preset terminal, wherein the cut line alarm signal is used for indicating that the current vehicle-mounted positioning terminal is in a cut line abnormal state.
If the gravity acceleration and the inclination angle of any axis of the coordinate axis are both 0, it is preliminarily stated that the vehicle-mounted positioning terminal does not fall off or is detached, and if the inclination angle is 0 and the voltage value is 0, it is further stated that the current vehicle-mounted positioning terminal is in a clipped abnormal state, a clipped alarm signal is sent to a preset terminal, and the clipped alarm signal is used for indicating that the external power supply circuit of the current vehicle-mounted positioning terminal may be in a short-circuit state or a vehicle power supply device does not supply power to the vehicle-mounted positioning terminal.
According to the embodiment of the invention, the gravity acceleration value and the voltage value in the external power supply circuit of the vehicle-mounted positioning terminal are acquired by the inertial sensor in the vehicle-mounted positioning terminal; calculating the inclination angle of the vehicle-mounted positioning terminal according to the gravity acceleration value; and judging whether the vehicle-mounted positioning terminal is in an abnormal state or not according to the inclination angle and the voltage value, and if the vehicle-mounted positioning terminal is in the abnormal state, sending different alarm signals to a preset terminal corresponding to different abnormal states. Compared with the prior art, the embodiment of the invention does not modify the existing product, can save the hardware cost and reduce the volume of the existing vehicle-mounted positioning terminal. And various abnormal conditions which may appear on the vehicle-mounted positioning terminal are respectively provided with corresponding alarm prompts, and when the vehicle-mounted positioning terminal has problems, a user can timely know the reasons and conveniently maintain the vehicle-mounted positioning terminal.
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 invention.
Referring to fig. 3, fig. 3 is a schematic flowchart of another abnormality detection method for a vehicle-mounted positioning terminal according to an embodiment of the present invention, where the execution subject of the method is a server, and the server executes the method according to steps S301 to S304, and the method includes: step S301 to step S304.

Step S304, judging whether the positioning terminal cluster is in an abnormal state or not according to the inclination angle and the GPS position information, and if the positioning terminal cluster is in the abnormal state, sending different alarm signals to a preset terminal corresponding to different abnormal states.
The method for judging whether the positioning terminal cluster is in an abnormal state or not according to the inclination angle and the GPS position information, and if the positioning terminal cluster is in the abnormal state, sending different alarm signals to a preset terminal corresponding to different abnormal states comprises the following steps:
if the inclination angle of more than 2 vehicle-mounted positioning terminals in the positioning terminal cluster is larger than a preset angle value, and the GPS positions of more than 2 vehicle-mounted positioning terminals in the positioning terminal cluster are not in the same preset range, sending a dismantled alarm signal to the preset terminal; and the removed alarm signal is used for indicating that the current positioning terminal cluster is in a removed abnormal state.
If the inclination angle of more than 2 vehicle-mounted positioning terminals in the positioning terminal cluster is larger than a preset angle value, and the GPS positions of any 2 vehicle-mounted positioning terminals in the positioning terminal cluster are in the same preset range, sending a falling-off alarm signal to the preset terminal; and the falling alarm signal is used for indicating that the current positioning terminal cluster is in a falling abnormal state.
The preset range is used for determining whether the positioning terminal cluster is detached or falls off, for example, if the preset range is within 1 meter taking any one vehicle-mounted positioning terminal in the positioning terminal cluster as a center, and if the inclination angle of any axis of the positioning terminal cluster exceeding 2 vehicle-mounted positioning terminals is larger than a preset angle value and the GPS position of the positioning terminal cluster exceeding 2 vehicle-mounted positioning terminals is not within 1 meter taking the vehicle-mounted positioning terminal as a center, it indicates that the current positioning terminal cluster is in an abnormal state of being detached. If the inclination angle of any axis exceeding 2 vehicle-mounted positioning terminals in the positioning terminal cluster is larger than the preset angle value, and the GPS positions of any 2 vehicle-mounted positioning terminals in the positioning terminal cluster are all in the range of 1 meter by taking the vehicle-mounted positioning terminal as the center, the current positioning terminal cluster is dropped.
Optionally, on the premise that the inclination angle of any axis exceeding 2 vehicle-mounted positioning terminals in the positioning terminal cluster is larger than the preset angle value, whether the positioning terminal cluster is detached or falls off can be judged according to the linear distance of the 2 vehicle-mounted positioning terminals. Calculating the linear distance of 2 vehicle-mounted positioning terminals according to the GPS positions of the 2 vehicle-mounted positioning terminals, and if the linear distance of any 2 vehicle-mounted positioning terminals in the positioning terminal cluster is smaller than a preset distance, indicating that the positioning terminal cluster falls off; and if the linear distance of more than 2 vehicle-mounted positioning terminals in the positioning terminal cluster is greater than the preset distance, the positioning terminal cluster is dismantled.
