Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Before introducing the embodiments of the present application, an application context of the embodiments of the present application is explained first:
in the automotive industry, positioning technology occupies a particularly important place. The positioning technology is provided for users to use by internally arranging a positioning technology related module in a Global Navigation Satellite System (GNSS) or externally hanging the positioning technology related module in a System On Chip (SOC), thereby providing convenience for the life of the users.
Currently, in order to better receive signals, many manufacturers use a high-gain antenna on the car to enhance the receiving capability. However, the antenna receives the effective signal (i.e., the positioning signal) and also receives noise, and the noise is amplified synchronously after the effective signal is amplified. When the noise submerges the effective signal, the GPS is interfered, so that the problems of slow positioning, losing lock and even incapability of positioning can occur. In the product development stage, especially after the product is shipped, when the vehicle machine has the above problems, the supplier may be complained by the front loading yard of the vehicle machine or the user, thereby affecting the image of the supplier and even bringing about serious economic loss.
In the prior art, the main step of detecting whether the GPS is interfered is that a software engineer grabs a log generated when a problem device operates, and analyzes the log, thereby determining whether the GPS is interfered. However, since the amount of logs generated during the operation of the device is very large, a lot of time is consumed for capturing the logs, and the problems of long detection processing time and low efficiency exist.
Therefore, according to the interference detection method, device, equipment and storage medium of the GPS, the electronic equipment acquires GPS data, the GPS data comprises three parts of information, namely satellite information, antenna information and crystal oscillator state information, so that a detection result can be generated according to the GPS data and the pre-configured target GPS data, and the detection result is used for indicating whether the electronic equipment has the interference problem or not, time is not consumed for capturing logs, manual intervention analysis is not needed, the efficiency of detection processing is improved, and the detection processing time is shortened.
For example, the interference detection method of the GPS provided in the embodiment of the present application may be applied to an interface schematic diagram shown in fig. 1. Fig. 1 is an interface schematic diagram of an interference detection method of a GPS according to an embodiment of the present disclosure, so as to solve the above technical problem.
As shown in fig. 1, the interface is displayed on a touch display screen of a mobile phone, the interface displays a map of an area where a start position and a destination are located, and displays a plurality of routes in the map for a user to select according to the start position, the destination and traffic information of each road in the map. (e.g., 3 routes, route 1, route 2, and route 3, respectively, as shown in FIG. 1). Meanwhile, road condition reference information is also displayed in the interface, and the road condition reference information comprises: starting location, destination, current geographic location (represented by the black circle in fig. 1), today's restricted travel information.
When the positioning function of the mobile phone is started, the GPS data of the mobile phone can be acquired, and whether the interference problem exists in the mobile phone is judged according to the GPS data and the pre-configured target GPS data, so that the normal work of the GPS is ensured by taking corresponding measures in time when the interference problem is determined, the positioning problem of the GPS caused by the interference is avoided, and the normal trip of a user is ensured.
The positioning problem may include the following:
(1) the current geographic position cannot be displayed in the map;
(2) the current geographic position in the map is abnormally changed (for example, within one second, the current geographic position is changed from the place A to the place C (not shown in fig. 1), the place A is far away from the place C, and the place A cannot reach the place C in one second by walking or riding a vehicle);
(3) the speed of displaying the current geographical position in the map is slow.
Optionally, the measure corresponding to the interference may be to restart the GPS of the mobile phone, or perform cold start on the mobile phone, or the like.
It can be understood that the execution main body in the embodiment of the present application may be a terminal device, for example, a tablet computer, a mobile phone, and the like, and may also be a car machine. Therefore, the present embodiment is explained by referring to the terminal device and the vehicle machine collectively as the electronic device, and it can be determined as the actual situation as to whether the electronic device is specifically the terminal device or the vehicle machine.
The technical solution of the present application will be described in detail below with reference to specific examples.
It should be noted that the following several specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a method for detecting interference of a GPS according to an embodiment of the present disclosure. As shown in fig. 2, the interference detection method of the GPS may include the steps of:
s201, acquiring GPS data of the electronic equipment.
The application scenario of the embodiment of the application can be a use stage after the electronic device leaves a factory, namely, GPS data of the electronic device is obtained when a user uses the electronic device; the method can also be used in the research and development stage of the electronic equipment, namely, the GPS data of the electronic equipment is acquired in the research and development stage so as to verify or predict whether the electronic equipment has the interference problem, thereby ensuring the quality of the electronic equipment which leaves the factory.
Optionally, the GPS data of the electronic device may be obtained in real time or according to a preset frequency, and the GPS data of the electronic device may also be obtained when the electronic device has a positioning problem, which is not particularly limited in the embodiment of the present application.
Because there are many reasons causing the positioning problem of the electronic device, such as interference problem, software function conflict, antenna drop, hardware fault, satellite fault, etc., the reason causing the positioning problem can be further determined when the electronic device has the positioning problem, so that corresponding measures can be taken for processing. For example, when the cause is an interference problem, the problem can be solved by restarting the GPS of the electronic device or performing cold start on the electronic device, so that the normal operation of the GPS can be recovered in a short time; when the reason is other than the interference problem, the electronic device needs to be returned to the factory for repair or the satellite needs to be further inspected, and the processing period is long. Therefore, when the electronic equipment has a positioning problem, the GPS data is acquired, corresponding measures can be taken in time to process the electronic equipment, the electronic equipment is prevented from being influenced by a user, and the use experience of the user is guaranteed.
In one implementation, the GPS data may be acquired through a system interface of the electronic device.
The GPS data comprises satellite information, antenna information and crystal oscillator state information, the satellite information comprises a carrier-to-noise ratio, a pitch angle and an azimuth angle, and the antenna information comprises antenna gain and antenna signal amplitude.
Optionally, the satellite information may be obtained through a positioning satellite signal, and the crystal oscillator state information may include a crystal oscillator correction amplitude, where the crystal oscillator correction amplitude is a difference between crystal oscillator related data at adjacent times.
Optionally, the satellite information may further include the number of valid satellites and the number of satellites exceeding the preset satellite signal strength.
And S202, generating a detection result according to the GPS data and the preset target GPS data.
The detection result is used for indicating whether the electronic equipment has the interference problem or not, so that the electronic equipment can be timely processed when the interference problem exists.
Alternatively, the target GPS data may be determined from parametric data, experimental data, or historical GPS data provided by a chip manufacturer of the electronic device.
For example, experiments can be performed in an open area without any occlusion, the highest signal value of the satellite signal is determined, and the target satellite information is determined according to the obtained highest signal value. For example, the highest signal value typically corresponds to a carrier-to-noise ratio of 40dBm to 43 dBm.
For example, the target antenna gain may be determined according to a parameter of the antenna path, such as the target antenna gain may be a maximum gain of the antenna path. Optionally, the maximum gain of some chips can be automatically adjusted according to the environment.
For example, the target antenna signal amplitude and the target crystal oscillator state information may be determined according to parameter data provided by a chip manufacturer.
It should be appreciated that determining the target GPS based on historical GPS data may refer to the embodiment shown in fig. 3, and will not be described in detail herein.
Optionally, the target GPS data may be a specific numerical value or a numerical range, and may be determined according to an actual situation, which is not specifically limited in the embodiment of the present application.
Optionally, the target GPS data includes target satellite information, target antenna information, and target crystal oscillator state information, the target satellite information may include a target carrier-to-noise ratio, a target pitch angle, and a target azimuth angle, and the target antenna information includes a target antenna gain and a target antenna signal amplitude.
Optionally, the target crystal oscillator state information includes a target crystal oscillator correction amplitude, and the target satellite information may further include the number of target effective satellites and the number of target satellites exceeding the preset satellite signal strength.
Illustratively, the target carrier-to-noise ratio may be a carrier-to-noise ratio interval exceeding 50dBm, the target pitch angle and the target azimuth angle may be an angle interval smaller than 0 degrees, the target antenna gain may be a gain interval exceeding 40dBm, the target antenna signal amplitude may be an amplitude interval exceeding 300, and the target crystal oscillator correction amplitude may be an amplitude interval exceeding 1000.
For example, the number of target effective satellites may be 0, the number of target satellites may be 3, and the preset satellite signal strength is 50 dbm.
It should be understood that the target GPS data may also include other values, which may be determined according to actual situations, and this is not specifically limited in this embodiment of the present application.
According to the interference detection method of the GPS, the electronic equipment obtains the GPS data of the electronic equipment and generates a detection result according to the GPS data and the pre-configured target GPS data, and the detection result is used for indicating whether the electronic equipment has the interference problem or not. In the technical scheme, the process of capturing the log is replaced by acquiring the GPS data, so that the detection processing time is shortened, and the detection processing efficiency is improved. In addition, in the prior art, when the electronic equipment has a positioning problem, the electronic equipment needs to be returned to a factory for analysis by a software engineer, and a user cannot normally use the electronic equipment in an analysis stage. In the application, if the electronic equipment has a positioning problem, real-time detection is started according to the GPS data and the target GPS data, manual intervention is not needed, the labor cost is saved, and the normal use of a user is ensured.
Optionally, in some embodiments, the step S202 may be implemented by: judging whether the GPS data is the same as the target GPS data, if so, generating a first detection result, wherein the first detection result is used for indicating that the electronic equipment has an interference problem; and if not, generating a second detection result, wherein the second detection result is used for indicating that the electronic equipment has no interference problem.
That is, when the satellite information is equal to the target satellite information, the antenna information is equal to the target antenna information, and the crystal oscillator state information is equal to the target crystal oscillator state information, a first detection result is generated, and when any one of the information is not equal to the corresponding target information (if the satellite information is not equal to the target satellite information), a second detection result is generated.
It should be appreciated that where the target GPS data is a range of values, determining whether the GPS data is the same as the target GPS data may be accomplished by determining whether the GPS data is within the data range of the target GPS data.
In the embodiment, the detection result is generated by judging whether the GPS data is the same as the target GPS data, so that different processing modes are adopted according to different detection results subsequently, and the accuracy of subsequent processing on the interference problem is improved.
Optionally, in some embodiments, when the first detection result is generated, the GPS of the electronic device is restarted or the electronic device is cold started; when a second detection result is generated and the electronic equipment has a positioning problem, outputting first reminding information, wherein the first reminding information is used for reminding a worker that the positioning problem is not caused by an interference problem.
It should be understood that, when generating the first detection result, other existing processing manners may also be adopted to solve the interference problem, and the application does not limit the specific means for processing the interference.
Optionally, when the GPS of the electronic device cannot be restarted or the electronic device is subjected to cold start, fourth reminding information may be generated, where the fourth reminding information is used to remind a user to manually restart the GPS of the electronic device, or manually cold start the electronic device, or manually restart the electronic device.
Optionally, outputting the first reminding information may be implemented by:
(1) displaying the first reminding information in a display screen of the electronic equipment;
(2) and sending the first reminding information to terminal equipment associated with the staff.
In the above embodiment, the corresponding processing step is executed on the electronic device according to the detection result, so that the interference problem is solved in time by restarting the GPS or cold starting the electronic device when the interference exists, or the worker is notified when the non-interference problem exists, so that the worker can process the problem existing in the electronic device in time, and the timeliness of processing the problem is improved.
The existing method for solving the interference problem is mainly to power off and restart the electronic equipment, but the method is very inconvenient and the user experience is poor. The scheme solves the interference problem by restarting the GPS or cold starting electronic equipment, does not influence the normal use of the electronic equipment by a user, and ensures the use experience of the user.
Optionally, in some embodiments, after the GPS of the electronic device is restarted or the electronic device is cold started, the GPS data is reacquired, and it is determined whether the reacquired GPS data is the same as the target GPS data; if the first reminding information is different from the second reminding information, outputting second reminding information, wherein the second reminding information is used for reminding workers that the interference problem is solved; if the first reminding information is the same as the second reminding information, outputting third reminding information, wherein the third reminding information is used for reminding a worker that the interference problem cannot be solved by restarting the GPS or performing cold start on the electronic equipment.
In the embodiment of the application, after the GPS of the electronic equipment is restarted or the electronic equipment is cold started, the GPS data can be obtained again to verify whether the interference problem is solved or not, so that related workers are timely notified when the interference problem is not solved, and the influence on the normal use of a user is avoided.
The outputting of the second reminding information and/or the third reminding information can be realized by the following method:
(1) displaying the second reminding information and/or the third reminding information in a display screen of the electronic equipment;
(2) and sending the second reminding information and/or the third reminding information to terminal equipment associated with the staff.
Optionally, in some embodiments, before acquiring the GPS data of the electronic device, a daemon process may be run, where the daemon process is used to detect whether the electronic device has an interference problem. Accordingly, S201 may be implemented by: and acquiring GPS data through a daemon process.
In the above embodiment, since the interference problem is not a problem that necessarily occurs, it is possible to prevent the occurrence of interference by algorithmically resolving GPS data in the development stage. Meanwhile, the scheme can be integrated into a system daemon process, as long as the electronic equipment starts a positioning function, the radio frequency is started, the active antenna is powered on, and whether the electronic equipment has an interference problem or not can be checked through the system daemon process, so that the time for researching, developing and analyzing the problem is saved, and the timeliness of subsequent interference processing is guaranteed.

As shown in fig. 3, based on any of the above embodiments, before acquiring GPS data, the method for detecting GPS interference may further include the following steps:
s301, historical GPS data in the absence of interference and historical GPS data in the presence of interference are obtained.
The historical GPS data corresponding to the electronic device when there is no interference and when there is interference, and the historical GPS data corresponding to other electronic devices of the same model as the electronic device when there is no interference and when there is interference, may be obtained.

In one possible implementation, the value range of each piece of information in the GPS data without interference can be determined from historical GPS data without interference. Correspondingly, the numerical range of each information in the GPS data under the interference condition can be determined according to the historical GPS data under the interference condition, so that the target GPS data can be determined according to the two numerical ranges. Optionally, the value range of the target GPS data may be smaller than or equal to the value range of the GPS data in the presence of interference.
In the embodiment, the target GPS data is determined according to the historical GPS data without interference and the historical GPS data with interference, so that the accuracy of determining whether the electronic equipment has interference or not according to the target GPS data is improved.
