Detailed Description

According to the official data provided by the ministry of industry and communications in 2015, the popularity of the terminals (especially mobile phones) reaches 95/hundred, that is, almost every person owns one terminal. Meanwhile, with the high-speed development of the internet of things card, especially the internet of things card carrying International Mobile Subscriber Identity (IMSI) information and the requirement of the country for the name system of the internet of things card, each terminal has at least one internet of things card or virtual internet of things card carrying IMSI information. The invention provides a road condition monitoring method by utilizing the dynamic position information of the terminal carrying the IMSI information according to the universality and uniqueness of the terminal carrying the IMSI information, thereby being capable of timely warning the current condition of a road for a user. Compared with the prior art, the method is mainly based on the existing public mobile communication network, and does not need to install a large amount of accessory equipment (such as a camera and an RFID scanner) or require the user side to actively install additional software (such as a vehicle-mounted system and a terminal APP), so that the installation cost of the equipment can be greatly reduced, the deployment of a complex network is avoided, and the requirement on the user side can be reduced.

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example one

As shown in fig. 1, which illustrates a road condition monitoring method provided by an embodiment of the present invention, as can be seen from the figure, the method may include the following steps:

s110, receiving terminal position information, time information and IMSI information of the terminal in an effective cell, which are acquired by a signaling acquisition system of a cellular mobile communication network in real time; the effective cell is a cellular cell in which an expressway and an expressway service area are located;

here, since the road condition monitoring scheme provided by the embodiment of the present invention is implemented based on information collected by a signaling collection system of a cellular mobile communication network, a monitored object is a mobile terminal under the cellular network, and the mobile terminal is not only held by vehicles on a road, but also held by pedestrians on the road (especially, urban roads) to carry IMSI information, in practical applications, the valid cell is usually a cellular cell in which an expressway and an expressway service area are located.

It should be noted here that in an actual cellular mobile communication system, the signaling collection system usually uses the collected IMSI information to distinguish the mobile Subscriber, and the information is usually stored in a Subscriber Identity Module (SIM) card or a virtual SIM card of a terminal held by the mobile Subscriber. Since one terminal can usually be plugged in 1 or 2 SIM cards, or can also correspond to 1 or 2 virtual SIM cards, the IMSI information used here to distinguish the mobile subscriber can also be used to distinguish different terminals (i.e. different vehicles traveling on the road).

S120, calculating and recording the driving speed and the driving direction of each terminal currently located in the same effective cell according to the terminal position information, the time information and the IMSI information of the terminal in the effective cell at regular time according to a preset time interval;

it can be understood that when the location information of a certain terminal in an active cell at different times is known, the current driving speed and driving direction of the terminal can be easily calculated. For example, the position of the active cell where a certain terminal (i.e., IMSI _1) is located at 13:20 is position a, and the position of the active cell where the terminal is located at 13:30 is position B, so that it is easy to obtain the traveling speed of the terminal as follows: (difference in distance between position a and position B)/10 minutes, the direction of travel is from position a to position B.

S130, determining the road condition covered by each effective cell and the terminal driving state in each effective cell according to the driving speed and the driving direction of each terminal currently in the same effective cell;

and S140, carrying out early warning reminding on the terminals in the effective cells according to the road condition covered by each effective cell and the terminal driving state in each effective cell.

For example, as to step S110, the receiving, in real time, terminal location information, time information, and IMSI information of the terminal in the active cell, which are collected by the signaling collection system of the cellular mobile communication network, as shown in fig. 2, may specifically include the following steps:

s1101, acquiring cell information of the effective cell; the cell information of the effective cell comprises cell identification and position information of the effective cell;

here, it can be understood that, since the technical solution provided by the embodiment of the present invention implements the monitoring of the road condition based on the terminal carrying the IMSI information, the monitored object must be the terminal on the monitored road, and therefore, here, it is first required to specify the road to be monitored (i.e. the expressway) and the cell where the road service area to be monitored (i.e. the expressway service area) is located. The Cell identity of the active Cell is used to uniquely identify the Cell, and for example, a Cell identity (Cell ID) may be used to uniquely identify the Cell.

S1102, receiving signaling information acquired by a signaling acquisition system of the mobile cellular network in real time; the signaling information comprises a cell identifier of a cell where a terminal carrying IMSI information is currently located, position information and time information of the terminal and IMSI information of the terminal;

here, it is understood that the location information of the terminal is collected by a signaling collection system of a mobile cellular network, and in general, the location information of the terminal is the location information of a cell in which the terminal is located.

S1103, judging whether the cell identifier of the cell where the terminal is currently located belongs to the cell identifier of the effective cell; if yes, go to step S1104; otherwise, returning to execute the step S1102;

it can be understood that, because the signaling information collected by the signaling collection system is the signaling information reported by all cells in the cellular mobile network, and the technical solution provided by the embodiment of the present invention is mainly applied to the terminal of the effective cell, when the signaling information collected by the signaling collection system is received, it is first necessary to determine whether the cell where the terminal is currently located is the effective cell, that is, to determine whether the cell identifier of the cell where the terminal is currently located belongs to the cell identifier of the effective cell.

S1104, storing the position information, the time information and the IMSI information of the terminal.

Here, it should be noted that, in order to be able to subsequently warn the terminal in the effective cell of the road condition of the effective cell through which the terminal is going to pass, after step S1101, the relative position relationship between the effective cells needs to be determined according to the position information of the effective cell and the lane direction of the highway covered by the effective cell.

It can be understood that, because the active cells are the cell in which the expressway and the expressway service area are located, and the lane direction of the expressway is fixed, there is only a front-back relationship between each two adjacent active cells. For example, as shown in fig. 3, when a vehicle travels forward on a highway, it passes through a cell a and then passes through a cell B, the cell a is referred to as a front cell of the cell B, and the cell B is referred to as a rear cell of the cell a. Therefore, after the platform for implementing the road condition monitoring method acquires the position information of the cell a and the cell B through a signaling acquisition system of a cellular mobile communication network, the relative position relationship between the cell a and the cell B can be easily determined by combining the lane directions of the expressway covered by the cell a and the cell B.

As shown in fig. 4, when the vehicle travels forward on the highway, the vehicle can reach the cell C through the cell a and can reach the cell C through the cell B, so that the cell a and the cell B are both front-end cells of the cell C, and the cell C is a rear-end cell of the cell a and the cell B. Similarly, after the platform for implementing the road condition monitoring method acquires the position information of the cell a, the cell B and the cell C through a signaling acquisition system of the cellular mobile communication network, the platform can easily determine the relative position relationship among the cell a, the cell B and the cell C by combining the lane directions of the expressway covered by the cell a, the cell B and the cell C. Based on this, in practical application, two adjacent effective cells in the same lane direction may be arranged in series, for example, on a certain expressway, vehicles successively pass through the cell 1, the cell 2, the cell 3, the cell 4, and the cell 5 according to the front-back order of the lane direction of the expressway, so that the result of arranging the cells in series on the expressway according to the order of the vehicles passing through the cells is as follows: cell 1, cell 2, cell 3, cell 4, cell 5, and all of cells 2 to 5 may be referred to as a post-cell of cell 1, i.e., a cell through which a vehicle may be about to pass when it is in cell 1.

For example, for step S130, the determining the road condition covered by each effective cell and the terminal driving state in each effective cell according to the driving speed and the driving direction of each terminal currently in the same effective cell may specifically include:

Correspondingly, for step S140, the performing an early warning prompt on the terminal in each effective cell according to the road condition covered by each effective cell and the terminal driving state in each effective cell may specifically include:

acquiring the road condition covered by a rear cell within an S1 kilometer distance from the effective cells according to the relative position relationship between the effective cells; when the highway covered by any post-cell within S1 kilometers away from the effective cell is in a congestion state, carrying out early warning reminding on all terminals in the effective cell; wherein, S1 is a preset distance; the post cell is an effective cell through which a terminal in the effective cell is going to pass;

for example, as shown in fig. 5, a rear cell within ten kilometers from a cell a is a cell B, a cell C, and a cell D sequentially from near to far, and at this time, if a platform for implementing the above-mentioned road condition monitoring method knows in advance that an expressway covered by the cell C is in a congestion state, the platform may send warning information to vehicles traveling on the expressway covered by the cells a and B (for example, send short messages to terminals of the cells a and B), so as to remind that an expressway covered by the cell C in front of the vehicles in the two cells is in the congestion state.

Or, as shown in fig. 6, a rear cell within ten kilometers from the cell a includes a cell B, a cell C, a cell D, and a cell E, and it can be seen from the figure that branches, i.e., a road 2 and a road 3, appear at an intersection of a road 1 covered by the cell a, where the road covered by the cell B and the cell C is the road 2, and an expressway covered by the cell D and the cell E is the road 3, if a platform for implementing the above-mentioned road condition monitoring method can know in advance that the road 2 covered by the cell C is in a congested state, and the road 3 is in a smooth state, the platform can send warning information to vehicles running on the road 1 to inform that the road 2 ahead is in a congested state, so that a vehicle owner running on the road 1 can select a relatively smooth road 3 to run.

When the terminal in the effective cell is in a low-speed driving state, early warning reminding is carried out on the terminal which drives at a low speed;

when the terminal in the effective cell is in a parking violation state, early warning and reminding are carried out on the terminal which parks violating the regulations;

For example, as shown in fig. 7, a rear cell within ten kilometers of a service area covered by a cell 1 is a cell 2, a cell 3 and a cell 4 from near to far, and at this time, if it is known in advance that an expressway covered by the cell 3 is in a congested state, early warning information may be sent to an owner who has a rest in the service area covered by the cell 1, so as to inform the owner that the expressway covered by the cell 3 in front of the owner is in the congested state, so that the owner who has a rest in the service area may start after waiting for the road in front to be clear.

Or, as shown in fig. 8, there are a cell 2, a cell 3, a cell 4, and a cell 5 in a postpositive cell ten kilometers away from a service area covered by the cell 1, and it can be seen from the figure that there are two selectable roads, namely, a road a and a road B, exiting from the service area, where the road covered by the cell 2 and the cell 3 is the road a, and the road covered by the cell 4 and the cell 5 is the road B, and at this time, if it is known in advance that the road B covered by the cell 5 is in a congested state and the road a is in a smooth state, it may send an early warning message to the owner who is resting in the service area to notify that the road B ahead is in a congested state, so as to facilitate the owner staying in the service area to select the road a to go out.

Example two

In order to facilitate understanding of the above technical solutions, as shown in fig. 9, an embodiment of the present invention will provide a specific implementation process of the above technical solutions applied to an expressway and an expressway service area, and as can be seen from the figure, the implementation process may include the following steps:

s201, acquiring cell information of an effective cell; the effective cell is a highway and a cell where a highway service area is located; the cell information of the effective cell comprises cell identification and position information of the effective cell;

s202, determining a relative position relation between the effective cells according to the position information of the effective cells and the lane direction of the expressway;

s203, after the relative position relation between the effective cells is determined, receiving the signaling information acquired by a signaling acquisition system of the mobile cellular network in real time; the signaling information comprises a cell identifier of a cell where a terminal carrying IMSI information is currently located, position information of the terminal, IMSI information of the terminal and a time tag;

here, it should be noted that the time tag is a specific time when the signaling information is acquired by the signaling acquisition system, that is, a specific time of a cell in which the terminal is located. It can be understood that, since the technical solution provided by the embodiment of the present invention is implemented by relying on the existing public mobile communication network resources, the signaling acquisition system described herein is a signaling acquisition system of a mobile cellular network.

S204, judging whether the cell identifier of the cell in which the terminal is currently located belongs to the cell identifier of the effective cell; if yes, go to step S205; otherwise, executing step S203;

s205, storing IMSI information of the terminal, position information of the terminal and a time tag as a basic information data unit;

here, it is understood that the basic information data unit includes three-dimensional information, i.e., IMSI information of the terminal, location information of the terminal, and a time stamp.

S206, sequentially acquiring all IMSI information of the same effective cell from all stored basic information data units at regular time according to a preset time interval by taking the stored position information of the terminal as a search dimension;

for example, if the stored basic information data unit includes a cell a, a cell B, and a cell C, all IMSI information of the cell a, the cell B, and the cell C may be sequentially obtained from all the stored basic information data units with the cell a, the cell B, and the cell C as a search dimension, as shown in (a) of fig. 10, all IMSI information belonging to the cell a is IMSI _1, IMSI _2, IMSI _3, and IMSI _4, as shown in (B) of fig. 10, all IMSI information belonging to the cell B is IMSI _5, IMSI _6, and IMSI _7, as shown in (C) of fig. 10, all IMSI information belonging to the cell C is IMSI _8, IMSI _9, and IMSI _ 10.

S207, sequentially acquiring basic information data units with the same IMSI information from all stored basic information data units by taking all IMSI information of the same effective cell as a search dimension;

as can be seen from fig. 10 (a), the IMSIs belonging to the cell a are IMSI _1, IMSI _2, IMSI _3, and IMSI _4, and therefore, further, with IMSI _1, IMSI _2, IMSI _3, and IMSI _4 as a search dimension, the basic information data units corresponding to IMSI _1, IMSI _2, IMSI _3, and IMSI _4 are sequentially obtained from all the stored basic information data units, where the basic information data unit corresponding to IMSI _1 is as shown in fig. 11, and the basic information data units corresponding to IMSI _2, IMSI _3, and IMSI _4 have similar contents to the basic information data unit corresponding to IMSI _1 shown in fig. 11, and therefore are not shown here.

S208, calculating and recording the driving speed and the driving direction of the terminal according to the position information and the time label of the terminal, which are stored in the basic information data unit with the same IMSI information;

from FIG. 11, it can be seen that the terminals carrying the same IMSI informationAnd the terminal calculates the driving speed and the driving direction of the terminal according to the position information and the time label of the terminal, which are stored in the basic information data unit with the same IMSI information. For example, as can be seen from the basic information data unit corresponding to IMSI _1 shown in fig. 11, at t₁When the terminal carries the IMSI _1, the position information of the terminal is the central point (x) of the cell A on the covered road₁,y₁) B, carrying out the following steps of; at t₂When the terminal carries the IMSI _1, the position information of the terminal is the center point (x) of the cell B on the covered road₂,y₂) (ii) a At t₃When the terminal carries the IMSI _1, the position information of the terminal is the center point (x) of the cell C on the covered road₃,y₃) (ii) a Therefore, the traveling speed v of the terminal carrying IMSI _1 can be calculated according to the following equation (1)_{IMSI_1}. According to the time sequence of t₁,t₂,t₃Therefore, the terminal carrying IMSI _1 travels from cell B to cell C.

S209, analyzing the recorded running speed and running direction of each terminal currently in the same effective cell, and determining the highway condition of each effective cell and the terminal running state in each effective cell;

specifically, when the ratio of the number of terminals having the same driving direction and driving speed less than a first preset threshold value among terminals currently located in the same effective cell to the number of all terminals having the same driving direction in the same effective cell is greater than a second preset threshold value, determining that a highway covered by the same effective cell is in a congestion state; and the number of the first and second groups,

S210, performing early warning reminding on the terminals in the effective cells according to the highway condition covered by each effective cell and the terminal driving state in each effective cell and by combining the relative position relation between the effective cells.

Specifically, according to the relative position relationship between the effective cells, the road condition covered by a rear cell within a distance of S1 km from the effective cell is obtained; when the highway covered by any post-cell within S1 kilometers away from the effective cell is in a congestion state, carrying out early warning reminding on all terminals in the effective cell; wherein, S1 is a preset distance; the post cell is an effective cell through which a terminal in the effective cell is going to pass; and the number of the first and second groups,
