detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Aiming at the problems of traffic congestion and low traffic capacity in the construction area at the present stage, but no systematic safety management and control countermeasures, the present invention proposes a method for controlling the operating state of the construction area based on geomagnetic vehicle detectors. As shown in Figures 1 and 2, it specifically includes:

Step 1: The distributed geomagnetic vehicle detector array collects the running status data of the vehicles in the construction area in real time, and transmits the running status data to the roadside processing unit through the ZigBee wireless communication protocol; wherein, the running status data includes: the time when the vehicle arrives in the construction area Information, location information, vehicle length information, vehicle speed information;

Step 2: The roadside processing unit performs data analysis and processing on the running status data, that is, the ID code of each geomagnetic vehicle detector and the source of the running status data, matches the running status data with the lane, and obtains the full information perception of time and space in the construction area: Time, position, speed, flow, vehicle length, headway, vehicle occupancy time;

Step 3: The roadside processing unit transmits the running status data, the equipment information of the geomagnetic vehicle detector and the full information perception to the cloud server through 3G; the equipment information of the geomagnetic vehicle detector includes the ID code of each geomagnetic vehicle detector and the ID code of each geomagnetic vehicle detector. The source information of the operation status data;

Step 4: The upper computer system connects to the cloud server database to obtain the operation status data and full information perception. The upper computer display uses graphs and tables to display the traffic operation status data in the construction area, and performs data analysis and processing to obtain the analysis and processing data;

Among them, the above-mentioned data analysis mainly includes statistics of the traffic volume in the construction area based on the operating status data, analysis of the trend of traffic volume over time, analysis of the change of the large vehicle rate, analysis of the average speed of vehicles, statistics of vehicle occupancy, and comparison of different time periods and different The cross-section data analyzes the vehicle running status in the construction area; the analysis and processing data include the traffic volume in the construction area, the trend of traffic volume change, the change status data of the large vehicle rate, the average speed of vehicles in the construction area, the vehicle occupancy rate, and the vehicle operation status data in the construction area, etc. .

Step 5: The host computer system calculates and generates control strategies using cloud computing methods;

Step 6: The upper computer generates control information according to the running status data, full information perception and control strategy;

Step 7: The upper computer releases the control information to multiple variable information boards on the roadside of the construction area through wireless communication.

In the above step 1, the distributed geomagnetic sensor array is used to realize the spatiotemporal full information perception of the traffic operation status in the construction area and the fine collection of data. The geomagnetic vehicle detector detects the state of the vehicle based on the Gaussian theory of the geomagnetic field. When the ferromagnetic substance of the vehicle passes through the detector, a continuous disturbance is generated on the magnetic field strength at this point, and the sampled data of the magnetic sensor is compared with the initial sampled data (the value of the earth's magnetic field at this point), and the difference is The influence of the earth's magnetic field at this point can be used to judge the state of the vehicle: with a car, without a car, moving, and stationary. On the basis of a single geomagnetic detector to determine the state of the vehicle, a distributed geomagnetic sensor array is used to give each geomagnetic sensor unit an ID code. By identifying the source of the data, the matching of the detection data and the lane is realized. This method is not only simple and easy to operate, It can also accurately reflect the vehicle information in each section of the construction area and in each lane. The information of each detector is transmitted to the roadside processing unit through the ZigBee wireless communication protocol to obtain the full information perception of time and space in the construction area: time, position, speed, flow, vehicle length, headway, and vehicle occupancy time. The data is transmitted to the cloud server through 3G. The above-mentioned magnetic vehicle detector, roadside processing unit, and server adopt multi-sensor array, wireless network communication technology, and cloud computing storage to realize the collection and aggregation of multi-lane traffic status in the construction area.

In the above step 3, the roadside processing unit transmits the operating status data, the equipment information of the geomagnetic vehicle detector and the full information perception to the cloud server through 3G, that is, the data is transmitted to the cloud server by means of data integration transmission, and stored in the SQL Server database , then there is no need to build another server to store relevant data in the construction area, which solves the problem of power supply in the construction area and the difficulty of storing a large amount of data in the construction area. The roadside processing unit aggregates the transmitted data and transmits it to the cloud server, and the host computer accesses the cloud server to extract relevant data. Among them, the upper computer is a computer that can directly issue control commands, and the upper computer software can display indicators such as speed and flow in real time through charts, reflecting the current operating status of the construction area from a micro level.

The cloud computing method adopted in the above step 5 realizes information aggregation and calculation of control strategies, and solves problems such as lack of power supply and storage capacity of local storage. The control information is calculated and obtained according to the traffic operation status data and control strategy, and the information is released to multiple variable information boards on the roadside of the construction area through wireless communication, so as to realize the control method of combining the driving behavior control of drivers in the micro and medium construction areas. Finally, a complete set of equipment for full information perception and fine control of traffic flow in the construction area will be formed to ease the traffic operation conditions in the construction area and improve the traffic capacity of the construction area. The above-mentioned cloud computing method is as follows: count the traffic volume in the construction area within a specific time period, and calculate the large vehicle rate and small vehicle rate in this time period; obtain the control threshold according to the large vehicle rate and small vehicle rate; calculate the traffic volume through the large vehicle rate and small vehicle rate Vehicle arrival rate in the construction area; compare the vehicle arrival rate with the control threshold to generate a control strategy. There are relevant definitions in the industry about the ratio of large vehicles and small vehicles. In this embodiment, the ratio of large vehicles is defined as the ratio of the number of large vehicles to the total number of vehicles, where a large vehicle is defined as a vehicle with a size greater than 7m from the depot, and the large vehicle The sum of the vehicle rate and the small vehicle rate is 1. Further, the control strategy is: by comparing the operating status data with the control threshold, the strategy for judging the vehicle driving route in the construction area, where the vehicle driving route strategy includes going straight, merging or turning, etc. Boot strategy.

A specific method to generate a control strategy is: the control strategy is limited by the traffic volume and the large vehicle rate, and the method of calculating the real-time vehicle arrival rate measured by the detector is as follows:

According to the length of the detected vehicle, it is judged whether it is a large vehicle. When the length of the vehicle is ≥ 7m, it is a large vehicle;

The conversion factor between the cart and the trolley is set to 3;

When the maximum vehicle rate is 0, set Q ₀ =1200pcu, Q ₄ =1800pcu, where Q is the real-time vehicle arrival rate (vehicle/hour) measured by the detector, and the Qi value under other large vehicle rates can be obtained by interpolation :

When 1≤i≤3, Q _i =(Q ₄ -Q ₀ )*i/4+Q ₀ (i=1, 2, 3);

Among them, large vehicle rate = large vehicle number/total vehicle number, small vehicle rate = 100% - large vehicle rate.

${\mathrm{<span\; class="notranslate">\; Q</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}^{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; -</span>{\mathrm{<span\; class="notranslate">\; hv</span>}}_{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; *</span>{\mathrm{<span\; class="notranslate">\; Q</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}^{\mathrm{<span\; class="notranslate">\; 0</span>}}<span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; hv</span>}}_{\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; *</span>{\mathrm{<span\; class="notranslate">\; Q</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}^{\mathrm{<span\; class="notranslate">\; 0</span>}}<span\; class="notranslate">\; *</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; ,</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 0</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 4</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; ;</span>$

Among them, hv _j is the high vehicle rate in j time period, is the i-th control threshold when the maximum vehicle rate is 0, is the i-th control threshold when the maximum vehicle rate is hv _j .

The control threshold obtained by the above formula is shown in Table 1 below:

In this embodiment, since the high vehicle rate can be calculated in real time, the corresponding calculation thresholds corresponding to the large vehicle rate are all obtained through the above calculation formula, and the above Table 1 is just some examples of calculation through the formula.

Calculate the Q and the large vehicle rate by counting the traffic volume for 60 minutes with the formula, apply the above table 1 to obtain the range of Q under the condition of the corresponding large vehicle rate, and use the following table 2 to obtain the display content of the variable information board:

The upper computer sends the control information in Table 2 to the automatic control device of the variable information release board installed on the roadside of the construction area. Different variable information release boards display different instruction information, as shown in Figure 3. The variable information release board 1-5 obtain the control information in the above table 2 respectively, and display the message of "parallel line" respectively. This technology achieves the control and intervention of the driver's micro-level merging position, and achieves the effect of fine control in the construction area; the display screen of the variable information release board 6 randomly displays the traffic conditions in the construction area ahead, including "smooth", " Congestion", "recommended driving speed", and "closed form of construction zone ahead" to realize the guidance of the driver's driving strategy at the mesoscopic level.
