The T-BOX can work normally and start to register to the TSP platform of the enterprise after the time awakening, when all the T-BOXs register to the TSP of the enterprise at the same time, the pressure of a server side of the TSP of the enterprise can be very high at the moment, network congestion is frequent, and a plurality of T-BOXs are caused to have registration failure so as to repeatedly register. After the T-BOX is awakened at regular time, if no upgrade or intelligent power supply is detected, the T-BOX enters dormancy again, and the detection process is generally completed after 2-3 minutes.
The currently defined timed wakeup time is generally the same time (for example, two early morning hours), and under the condition that the capacity of an enterprise TSP platform server is limited, when the number of vehicles reaches a certain degree, the situation that all T-BOXs are simultaneously waken and register networks simultaneously occurs, so that network congestion is caused.

Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, wherein it is to be understood that the following detailed description is for the purpose of illustration only and is not to be construed as limiting the scope of the invention, as various insubstantial modifications and adaptations of the invention to those skilled in the art may be made in light of the foregoing disclosure.
Example 1
As shown in fig. 1, the invention provides an optimization method for network congestion caused by batch network injection of T-BOX, which is applied to information interaction with a TSP platform based on TCP network communication after waking up T-BOX in a plurality of sleep states, and the T-BOX is sequentially waken up through preset wake-up time intervals.
The TSP platform (enterprise TSP platform) is a platform for managing all vehicles in a host factory, corresponding vehicle data is collected by the T-BOX and uploaded to the TSP platform through a wireless network, and each vehicle is bound and identified according to a vehicle VIN (vehicle unique identification number) and an ICCID number (20 bytes of numbers, such as 12345678901234567890) of a SIM card in the T-BOX.
The BOX is a legal part of the new energy electric vehicle, is responsible for collecting vehicle data and uploading the vehicle data to an enterprise TSP platform through a wireless network, and the TSP platform can also issue instructions to the T-BOX through the wireless network for execution.
The information interaction comprises intelligent vehicle power supply or vehicle upgrading package downloading, and after the information interaction is completed by the T-BOX, the T-BOX actively disconnects from the TSP platform.
The method comprises the following steps:
acquiring ICCID numbers of a built-in SIM card in the T-BOX after the T-BOX is electrified, preferentially acquiring interaction time of information interaction before the T-BOX enters dormancy, finishing intelligent power-on detection or judging whether the detection time to be upgraded is 2-3 minutes, setting a plurality of wakeup time intervals of the T-BOX to be longer than the interaction time, namely the wakeup time intervals are required to be at least longer than 3 minutes, carrying out equal batch wakeup on the plurality of T-BOX according to any one of preset wakeup sequence rules and the wakeup time intervals after the T-BOX enters dormancy, and carrying out information interaction after wakeup;
the wake-up sequence rule includes:
(1) Formulating according to the tail number of ICCID number: sequentially accumulating the wake-up time intervals when the tail numbers are sequentially increased by '1' or sequentially decreased by '1', and sequentially waking up a plurality of T-BOXs; when a wake-up sequence is formulated according to the tail number of the ICCID number, the T-BOX corresponding to the tail number of 0 or 9 is specifically a preferential wake-up batch, and a wake-up time stamp is preset in the T-BOX of the preferential wake-up batch.
(2) Making according to the tail number of ICCID number as odd number or even number: preferentially waking up the T-BOX with the tail number of odd or even, and waking up the T-BOX with the tail number of odd or even after accumulating the wake-up time interval; when a wake-up sequence is formulated according to the odd or even tail number of the ICCID number, the T-BOX corresponding to the odd or even tail number is a preferential wake-up batch, and a wake-up time stamp is preset in the T-BOX of the preferential wake-up batch.
When the T-BOX is in dormancy, when the system time of the T-BOX is operated to a wakeup time stamp, the T-BOX wakes up on time; before the T-BOX sleeps, the T-BOX calibrates the system time with reference to GPS time and network time in sequence. GPS acquires time with a little higher precision than network time, and in general, GPS is effective to use GPS time, and GPS is ineffective to use network time.
The tail number of the ICCID number in the invention is specifically any one of the serial numbers 0-9 of the 19 th byte in the ICCID number.
The meanings expressed by the ICCIDs of different operators are different, but the last five bytes must be determined, 4-byte serial number + 1-byte check code, exemplified in chinese mobile coding format:
89860 0MFSS YYGXXXXXXP, the previous field is not concerned, only the place where XX is concerned, the last 5 bytes are XXXXP, wherein XXXX represents a serial number, the range of each byte of the serial number is 0-9, the last byte of the serial number is evenly distributed in production, that is, the probability of 0-9 appearing in each data is the same. The last byte of the serial number (19 th byte of ICCID number) is taken for setting the dormancy wakeup time.
The above optimization method is further described below in connection with 2 practical cases:
the wake-up sequence rule is formulated according to the tail number of the ICCID number:
for example, the T-BOX wake-up time stamp with the tail number of 0 is set to 2 am; when the wakeup time interval is accumulated while incrementing "1" by the tail number: the T-BOX wake-up time with tail number 1 is set as: 10 minutes in 2 am; the T-BOX wake-up time with tail number 2 is set as: 20 minutes in the morning at 2 points; and so on, the tail number starts from 0 and is at most 9, and the wake-up time is increased by 10 minutes every 1 increment of the tail number, namely, the wake-up time interval is 10 minutes. When the wake-up time interval is accumulated by decrementing the tail number by '1', the T-BOX wake-up time stamp with the tail number of 9 is set to 2 am, and the T-BOX wake-up time with the tail number of 8 is as follows: 10 minutes in 2 am; the T-BOX wake-up time with tail number 7 is set as: 20 minutes in the morning at 2 points; and so on; this way the number of simultaneous registrations can be reduced to the previous tenth.
The wake-up sequence rule is formulated according to the tail number of ICCID numbers being odd or even:
when the T-BOX wake-up time stamps of tail numbers 0, 2, 4, 6 and 8 are set to be 2 am, after the accumulated wake-up time interval is 10 minutes, the T-BOX with tail numbers 1, 3, 5, 7 and 9 is waken up by 2.10 am.
It is apparent that the above method can effectively reduce the number of T-BOX registered for the TSP platform at the same time.
Of course, the wake-up time interval is not limited to 10 minutes in the present invention, and may be adaptively set for the data amount of the T-BOX under the TSP platform.
The tail numbers of the serial numbers in the ICCID of the SIM card in the T-BOX are evenly distributed after batch, the probability of 0-9 is the same, the equal-batch T-BOX registration can be realized by setting the tail numbers for time awakening, and the probability of network congestion caused by simultaneous registration of a large number of T-BOXs at the same time point is greatly reduced.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
