As shown in fig. 1 and fig. 2, in one embodiment, a vehicle-mounted mobile WIFI data processing method based on TBOX is provided, which specifically includes the following steps:
S101, monitoring data to be uploaded of TBOX, and determining the change speed of the data quantity of the data to be uploaded;
S102, judging whether the change speed is greater than a preset speed, if not, judging whether the data volume of the data to be uploaded reaches a first preset value, and if not, uploading the data to be uploaded to a server through a TBOX;
S103, if the data volume of the data to be uploaded reaches a first preset value, determining the actual time and the estimated time when the data volume of the data to be uploaded reaches a second preset value;
S104, determining the data volume uploaded by the TBOX and the data volume uploaded by the mobile WIFI according to the actual time and the estimated time when the data volume of the data to be uploaded reaches a second preset value, and uploading the data volume and the data volume uploaded by the mobile WIFI to a server through the TBOX and the mobile WIFI respectively;
s105, if the change speed is greater than the preset speed, judging whether the change speed is less than or equal to the average uploading speed of the TBOX, if so, uploading the newly-added data to a server through the TBOX and the mobile WIFI at the same time;
s106, if the change speed is larger than the average uploading speed of the TBOX, classifying the data to be uploaded and determining the classification priority;
and S107, selecting data to be uploaded in the classification with the front priority according to the priority of the classification and the average uploading speed of the TBOX, uploading the data to be uploaded to a server through the TBOX, and uploading all the data to be uploaded to the server through the mobile WIFI according to the priority of the classification.
In this embodiment, the TBOX reads data generated by the vehicle and uploads the data to the server, and the server may be a cloud end, in this process, the TBOX is in a state of continuously reading the data and continuously uploading the data, and if the uploading speed of the TBOX is less than the reading speed or the network adjustment of the place where the vehicle travels is not good and cannot upload the data in real time, the data will be accumulated in the TBOX and become the data to be uploaded. In normal running of an automobile, the data amount generated by data is generally not large, and the data generation speed is generally smaller than the average uploading speed of TBOX, so in normal running of the automobile, TBOX is enough to process the data generated by the automobile, but if faults or emergency occur, the sudden data amount can far exceed the normal state, at the moment, if the data generation speed is larger than the average uploading speed of TBOX, a large amount of data is accumulated in TBOX, and redundant storage space and transmission capacity are generally designed to prevent data loss, so that resource waste is caused.
In this embodiment, the change speed refers to an instantaneous speed at which the data amount of the data to be uploaded changes. The rate of change is the instantaneous rate of data generation minus the instantaneous rate of data upload. If the instantaneous speed of data generation is continuously greater than the instantaneous speed of data uploading, the change speed is positive, and the data amount of the data to be uploaded becomes large.
In this embodiment, the preset speed is used to determine whether the vehicle encounters a fault or an emergency, and when the vehicle encounters a fault or an emergency, a large amount of data is generated, the amount of data to be uploaded increases sharply, the change speed also increases suddenly and obviously, and when the change speed is greater than or equal to the preset speed, the vehicle encounters a fault or an emergency. The preset speed may be set to half the TBOX average upload speed. For example, the average uploading speed of TBOX is 10m/s, and the preset speed may be 5m/s. The average uploading speed of the TBOX refers to the average uploading speed of data in the normal running process of the vehicle, and the average uploading speed can be obtained through historical data.
In this embodiment, if the change speed is not greater than the preset speed, it means that the vehicle is not experiencing a fault or an emergency, but if the instantaneous speed of data generation is greater than the instantaneous speed of data uploading, the data will increase slowly. The average speed of the instantaneous speed of data uploading in a period of time is the average uploading speed of the TBOX, which means that the data to be uploaded gradually increases if the data to be uploaded is uploaded only by the TBOX.
In this embodiment, the first preset value may be set to 70% of the data storage capacity. And uploading the data according to the original uploading path without the data quantity of the data to be uploaded reaching the first preset value, namely uploading the data to be uploaded only by means of TBOX.
In this embodiment, the second preset value may be set to 80% of the data storage capacity. When the data amount of the data to be uploaded reaches the second preset value, uploading the data to be uploaded through mobile WIFI at the same time, and increasing a data uploading channel.
In this embodiment, the mobile WIFI refers to a device that can convert a mobile network signal into a WIFI signal, which may be a portable WIFI.
In this embodiment, the change speed is greater than the preset speed, and the change speed is less than or equal to the average uploading speed of the TBOX, and because the transmission of the data in the first time is important at this time in a fault or an emergency, the newly added data is uploaded through the mobile WIFI, and meanwhile, the TBOX continues to upload all the data to be uploaded, including the newly added data. Because the data uploading through the TBOX is more stable than the data uploading through the mobile WIFI, the data to be uploaded is transmitted through the TBOX under the normal condition, and the newly added data can be transmitted to the server through the mobile WIFI.
In this embodiment, for the server, the server receives two pieces of newly added data, and the newly added data with a large data volume may be used as final data, so that the situation that the newly added data may have packet loss in the transmission process may be avoided.
In this embodiment, if the change speed is greater than the average upload data of the TBOX, the most important data to be uploaded is uploaded through the TBOX, the next most important data to be uploaded is uploaded through the mobile WIFI, and it is ensured that the data can be uploaded to the server in the first time. It is necessary to classify the data to be uploaded and to determine the priority of the uploading.
According to the vehicle-mounted mobile WIFI data processing method based on the TBOX, the change speed of the data quantity of the data to be uploaded is determined by monitoring the data to be uploaded of the TBOX; judging whether the change speed is greater than a preset speed, if not, judging whether the data quantity of the data to be uploaded reaches a first preset value, and if not, uploading the data to be uploaded to a server through TBOX; if the data volume of the data to be uploaded reaches a first preset value, determining the actual time and the estimated time of the data volume of the data to be uploaded reaching a second preset value; determining the data volume uploaded by the TBOX and the data volume uploaded by the mobile WIFI according to the actual time and the estimated time when the data volume of the data to be uploaded reaches a second preset value, and uploading the data volume and the data volume uploaded by the mobile WIFI to a server through the TBOX and the mobile WIFI respectively; if the change speed is greater than the preset speed, judging whether the change speed is less than or equal to the average uploading speed of the TBOX, if so, uploading the newly added data to a server through the TBOX and the mobile WIFI at the same time; if the change speed is greater than the average uploading speed of the TBOX, classifying the data to be uploaded and determining the classification priority; and selecting data to be uploaded in the classification with the front priority according to the priority of the classification and the average uploading speed of the TBOX, uploading the data to be uploaded to a server through the TBOX, and uploading all the data to be uploaded to the server through the mobile WIFI according to the priority of the classification. When the change speed is not greater than the preset speed but the data volume of the data to be uploaded reaches a second preset value, determining the data volume uploaded by the TBOX and the data volume uploaded by the mobile WIFI, so that the transmission pressure of the TBOX can be shared by using a data transmission link of the mobile WIFI; when the change speed is greater than the preset speed and greater than the average uploading speed of the TBOX, the data to be uploaded with the front priority is selected to be uploaded to the server through the TBOX, all the data to be uploaded are uploaded to the server through the mobile WIFI, so that the data can be rapidly uploaded to the server in a short time, and meanwhile the transmission pressure of the TBOX is shared by a data transmission link of the mobile WIFI. In this way, more storage space and larger transmission capacity are not required to be designed in design to prevent data loss and untimely uploading, only the transmission pressure of the TBOX shared by the data transmission link of the mobile WIFI is required to be utilized to enable the channel for uploading data to be increased, the amount of the uploaded data to be increased so as to reduce the redundancy design of the storage space and the transmission capacity, and the problems that resources are wasted and the production and manufacturing cost are increased due to design redundancy and low-efficiency use range are solved.
In one embodiment, the determining the change speed of the data amount of the data to be uploaded includes:
Determining the values of the data quantity of a plurality of data to be uploaded and the time corresponding to the data quantity in a preset period every other preset period;
The values of a plurality of data amounts and the time corresponding to the data amounts are represented by points in a two-dimensional coordinate system;
performing curve fitting on a plurality of points on a two-dimensional coordinate system to obtain a curve of data volume and time of data to be uploaded;
And determining the change speed of the data quantity of the data to be uploaded in the preset period according to the change speed of the data quantity of the data to be uploaded at the end of the period obtained by the curve.
In the present embodiment, since the change speed is an instantaneous speed, the preset period is required to be as small as possible. For example, the preset period is set to be 1s, the value of the data quantity of the data to be uploaded and the time corresponding to the data quantity are determined every 0.2s within 1s, 5 points are obtained by representation on a two-dimensional coordinate system, a curve is obtained by curve fitting of the 5 points, the instantaneous speed at the moment when the curve is ended is calculated, and the change speed is used as the instantaneous speed of the 1 s.
In this embodiment, the horizontal axis of the two-dimensional coordinate system is time, the vertical axis is the data amount of the data to be uploaded, and the obtained curve is a curve in which the data amount of the data to be uploaded changes with time.
In one embodiment, determining the actual time and the estimated time for the data amount of the data to be uploaded to reach the second preset value includes:
obtaining estimated time for the data quantity of the data to be uploaded to reach a second preset value;
obtaining the actual time when the data quantity of the data to be uploaded reaches a second preset value;
Wherein B 2 is the data amount when the data amount of the data to be uploaded reaches the second preset value, B 1 is the data amount when the data amount of the data to be uploaded reaches the first preset value, v 1 is the change speed when the data amount of the data to be uploaded reaches the first preset value, t 2 is the time point when the data amount of the data to be uploaded reaches the second preset value, and t 1 is the time point when the data amount of the data to be uploaded reaches the first preset value.
In this embodiment, B 2、B1、t2、t1 is a data amount that can be directly determined. v 1 can be calculated.
In this embodiment, the estimated time for the data amount of the data to be uploaded to reach the second preset value refers to the estimated time for the data amount of the data to be uploaded to reach the second preset value from the first preset value with v 1 as the average speed.
In one embodiment, the determining the data volume uploaded by the TBOX and the data volume uploaded by the mobile WIFI according to the actual time and the estimated time when the data volume of the data to be uploaded reaches the second preset value includes:
Judging whether T 1 is smaller than or equal to T 2, if yes, obtaining the data volume uploaded by TBOX by , and obtaining the data volume uploaded by mobile WIFI by/> ;
If T 1 is greater than T 2, obtaining the data volume uploaded by TBOX by and obtaining the data volume uploaded by mobile WIFI by/> ;
Wherein T 1 is the estimated time when the data amount of the data to be uploaded reaches the second preset value, T 2 is the actual time when the data amount of the data to be uploaded reaches the second preset value, and a is the current data amount of the data to be uploaded.
In this embodiment, if the estimated time is less than or equal to the actual time, the change speed is reduced or unchanged, and at this time, the current data size of the data to be uploaded is divided into two parts, and the two parts are transmitted respectively through the TBOX and the mobile WIFI, so that the data size of the data to be uploaded is reduced.
In this embodiment, if the estimated time is longer than the actual time, the change speed is increased, and the data amount rises faster, that is, the data amount changes more in the same time, so that the data amount of is allocated to TBOX, and the data amount of/> is allocated to mobile WIFI, so that the data amount of the data to be uploaded is reduced. If the data volume is equally divided, a situation that data to be uploaded through the TBOX is accumulated may occur.
In one embodiment, the method further comprises the following steps of:
Acquiring a communication period of TBOX and mobile WIFI;
determines that the number of communication times d needs to be increased;
Increasing the number of communication connection times of the TBOX and the mobile WIFI according to d in a communication period;
Transmitting data to be uploaded by the mobile WIFI to the mobile WIFI in the communication connection of the TBOX and the mobile WIFI;
V 2 is the average uploading speed of the mobile WIFI to the server, and v 3 is the average transmission speed of the TBOX and the mobile WIFI.
In this embodiment, uploading the data to be uploaded to the server via the mobile WIFI essentially provides one more communication link for the TBOX. Therefore, the data to be uploaded, which is required to be uploaded to the server through the mobile WIFI, is transmitted to the mobile WIFI through the TBOX, the link from the TBOX to the server and the link from the TBOX to the mobile WIFI are not the same link, and communication between the two links is not interfered with each other.
In this embodiment is the quotient of v 2 divided by v 3, and since d is added, the number of communication connections between TBOX and mobile WIFI in a communication cycle is d plus 1. In practice, d is at least 1, so that the calculation can be performed using the next method, for example, the quotient of v 2 divided by v 3 is 0, but the remainder, then d is 1 according to the next method.
In this embodiment, for example, the communication period of obtaining TBOX and mobile WIFI is 0.2 s/time, and d is 1, and increasing the number of communication connections between TBOX and mobile WIFI according to d in the communication period indicates that the communication period between TBOX and mobile WIFI is changed to 0.1 s/time.
In one embodiment, the classifying the data to be uploaded and determining the priority of classification includes:
determining old data before a time point where the change speed is greater than the preset speed and newly-added data after the time point where the change speed is greater than the preset speed in the data to be uploaded;
setting three categories, namely a driving behavior category, an OBD data category and a remote management category;
Dividing old data and newly added data according to categories to obtain six categories;
the six classifications are sequenced according to a preset sequence;
and prioritizing the data to be uploaded of each category according to the time of data generation from new to old.
In the present embodiment, the data of the driving behavior class includes driving data and driving behavior events; the OBD class data comprises a vehicle data stream, a vehicle fault reading and a vehicle fault clearing; the management class data comprises remote upgrading, remote restarting, remote inquiry, remote setting, version reporting, SIM card information reporting and module self-checking. The driving behavior class has the highest priority, and the management class is the lowest among the OBD classes. However, since the new data may be in a fault or an emergency, the priority of the new data is higher than that of the old data, and thus the preset sequence may be driving behavior type-new data, driving behavior type-old data, OBD type-new data, management type-new data, OBD type-old data, and management type-old data.
In one embodiment, the selecting the data to be uploaded in the class with the front priority according to the priority of the class and the average uploading speed of the TBOX, and uploading the data to be uploaded to the server through the TBOX includes:
S701, selecting data to be uploaded in the classification with the highest priority to upload to a server through TBOX;
S702, calculating a preset transmission speed V 1 of data to be uploaded in the selected classification by ;
S703, judging whether V 1 is larger than or equal to the average uploading speed of TBOX, if so, maintaining the transmission of the data to be uploaded in the selected classification;
S704, if V 1 is smaller than the average uploading speed of the TBOX, uploading the data to be uploaded in the classification of the next priority and the data to be uploaded in the selected classification to a server through the TBOX;
S705, repeating S702-S704 until V 1 is greater than or equal to the average upload speed of TBOX;
wherein C is the data amount of the data to be uploaded in the selected category, and k 1 is the first preset time.
In this embodiment, the first preset time may be obtained according to a ratio of an average data amount of newly added data to be uploaded of the driving behavior class and an average uploading speed of the TBOX in the history data when a fault or an emergency occurs.
In this embodiment, for example, C is 50M, k is 10s, and V 1 is 5M/s, where V 1 refers to that if the average speed of uploading data to be uploaded in the classification is 5M/s at the first preset time, the average uploading speed of TBOX is not the actual average uploading speed of TBOX, and the average uploading speed of TBOX is irrelevant to the amount of uploaded data. In fact, if the average uploading speed of the TBOX is 10M/s, the actual uploading time is only 5s, and if new data is not generated, the remaining 5s is more free time, and the data to be uploaded of other classes should be continuously transmitted essentially, so when V 1 is smaller than the average uploading speed of the TBOX, the TBOX has redundant transmission capacity, and the data to be uploaded in the class of the next priority needs to be uploaded together.
In one embodiment, the uploading all the data to be uploaded to the server through the mobile WIFI according to the classified priority includes:
s801, determining classification uploaded to a server through TBOX;
s802, uploading the rest classifications to a server through the mobile WIFI according to the priority order;
s803, determining the data quantity D of the data to be uploaded in all the remaining classifications;
S804, calculating a preset transmission speed V 2 of the data to be uploaded in the selected classification by ;
S805, judging whether V 2 is smaller than the average uploading speed of the mobile WIFI, if yes, uploading the data to be uploaded in the classification uploaded to the server through the TBOX to the server again through the mobile WIFI;
s806, if V 2 is greater than or equal to the average uploading speed of the mobile WIFI, repeating S803-S805 until V 2 is less than the average uploading speed of the mobile WIFI;
