a lighting device 406, disposed on the top support, for illuminating the target road. The lighting device can be used for lighting a target road, and meanwhile, the phenomenon that a shot picture is too dark due to insufficient ambient brightness of the photoelectric device is avoided. In addition, the brightness of the lighting device can be set according to the requirements of a user.
And the projection device 407 is arranged on the top support and used for projecting and displaying the projection information sent by the processor in a preset area.

As shown in fig. 1, the vehicle control method based on the traffic control apparatus may include:
step 101, acquiring radar information, image information and geomagnetic pressure information of vehicles passing through each lane in a current period according to a radar device, a photoelectric device and a geomagnetic induction and pressure device.
In this embodiment, statistics may be performed on the information collected by the traffic control device periodically, for example, with a period of 30 seconds, the radar information collected by the radar device in the traffic control device, the image information collected by the photoelectric device, and the geomagnetic pressure information collected by the geomagnetic induction and pressure device are counted every 30 seconds.
In the present embodiment, the radar information, the image information, and the geomagnetic pressure information can all be used to separately calculate the number of vehicles in the period. The radar information may include: radar signal transmitting time points, radar signal receiving time points, radar signal reflection intensity and the like; the image information may include: image capturing time, image capturing interval, captured image, and the like; the geomagnetic pressure information may include: the change law of magnetic flux and pressure value, etc.
In an alternative embodiment, as shown in fig. 5, the obtaining of the radar information, the image information, and the geomagnetic pressure information includes:
step 501, controlling the radar device to emit radar signals according to a preset emission frequency in the width direction of each lane in the current period.
Step 502, obtaining radar reflection signals of the traffic flow in each lane to the radar signals, and obtaining reflection time points and reflection signal strength of the radar reflection signals as radar information.
In the present embodiment, as shown in fig. 2, in order to enable the radar signal to be reflected by the flow of the traffic in the lane, the radar device is installed at a lower position in the traffic control apparatus, for example, the installation position of the radar device may be a position of a half height of the vehicle, and the direction in which the radar device transmits the radar signal is the same as the width direction of the lane, which is the direction perpendicular to the lane, as shown in fig. 2. And then transmit the radar signal according to predetermined transmitting frequency, wherein the transmitting frequency can be based on the vehicle speed of this highway section and pass through the experiment and calibrate, can avoid the number of leaking of vehicle according to this frequency transmitting signal, can suitably reduce the consumption because of the radar signal causes moreover.
It can be understood that the radar signal is reflected when meeting the traffic flow, and then the radar reflection signal of the traffic flow in each lane to the radar signal can be obtained. And acquiring the transmitting time of the radar signal and the receiving time of the radar reflection signal, further averaging the transmitting time and the receiving time, and determining the reflection time point of the radar signal. In addition, since different vehicles have the reflection effect of the corresponding radar signals, the reflected signal strength of the radar reflection signal is acquired in order to determine whether the reflection is caused by the same vehicle.
Step 503, capturing a plurality of candidate image frames corresponding to a plurality of capturing frequencies in the current period as image information according to a preset capturing frequency.
In this example, the shooting frequency may be calibrated based on the vehicle running speed and according to an experiment, and shooting the image frames according to the shooting frequency can avoid the missing number of the vehicle and can appropriately reduce the power consumption caused by shooting the image information.
In the current period, shooting is carried out according to the preset shooting frequency, and a plurality of candidate image frames can be obtained and used as image information acquired by the photoelectric equipment.
Step 504, acquiring a preset sampling frequency, and acquiring a plurality of magnetic fluxes and a plurality of pressure values corresponding to the plurality of sampling frequencies in the current period as geomagnetic pressure information.
In this example, the geomagnetic induction and pressure device may be disposed below a road surface, the device may be powered by a street lamp power supply system, a geomagnetic induction portion in the device may be implemented based on an energized loop coil, and when a vehicle passes through the road surface embedded with the coil or stays on the road surface, the collected magnetic flux may change due to iron contained in the vehicle. It is understood that the pressure portion of the geomagnetic sensing and pressure device may be implemented based on a pressure sensor, and the pressure sensor can obtain a corresponding pressure value change when the vehicle passes through or stays on a road surface embedded with the pressure sensor. In the current period, sampling is performed according to a preset sampling frequency, so that geomagnetic pressure information containing magnetic flux and pressure values in the previous period is acquired.
In some application scenes, can also acquire the light intensity of environment through photoelectric device, because illumination is not enough, can make image information dark on the contrary, unclear, can use photoelectric device to acquire the light intensity of environment, if this environment light intensity is less than preset light intensity threshold value, then explain this environment light intensity and hang down, can use the lighting apparatus among the traffic control equipment to throw light on for environment light intensity is greater than preset light intensity. It is understood that the lighting device can also be used as a street lamp, and the lighting time and the lighting brightness of the lighting device can be adjusted according to the needs of users, such as: illuminating at a first brightness from 00:00 to 8:00 due to fewer vehicles and fewer pedestrians; the illumination is not carried out at 8:00-17:00 because the sunlight is sufficient, and the illumination is carried out at 17:00-24:00 because more vehicles and pedestrians exist, wherein the first brightness is darker than the second brightness.
After the radar information, the image information, and the geomagnetic pressure information of the passing vehicle are acquired, the following step 102 is continuously performed.
And 102, determining a first quantity, a second quantity and a third quantity of passing vehicles according to the radar information, the image information and the geomagnetic pressure information respectively.
In this embodiment, the corresponding number of passing vehicles is respectively obtained from three dimensions of radar information, image information and geomagnetic pressure information, where the number of passing vehicles obtained according to the radar information is a first number, the number of passing vehicles obtained according to the image information is a second number, and the number of passing vehicles obtained according to the geomagnetic pressure information is a third number.
In an alternative embodiment, a corresponding radar is installed for each lane, and the radar can be used for counting the number of vehicles, so that the radar information is the number of vehicles acquired by the radar corresponding to each lane, and thus the number of vehicles can be used as the first number. And the image information acquired by the photoelectric device is a video, vehicles in the video are identified through an artificial intelligence technology, and the number of vehicles which exit the video viewing range in the period is taken as a second number. Further, a magnetic flux change threshold value is set, and a change in magnetic flux greater than the magnetic flux change threshold value is regarded as one vehicle pass, so that the number of times that the change in magnetic flux in the cycle is greater than the magnetic flux change threshold value can be regarded as the third number.
In another alternative embodiment, the radar information includes a reflection time point and a reflection signal strength of a radar reflection signal, the image information includes candidate image frames, and the geomagnetic pressure information includes a magnetic flux and a pressure value, so that as shown in fig. 6, the first number, the second number, and the third number of passing vehicles in the current period may be obtained by:
step 601, determining a radar reflected signal set belonging to the same candidate vehicle according to the reflected signal intensity and the reflection time point.
And step 602, acquiring a reflection time point, determining the radar reflection time length of each radar reflection signal set, and calculating the product of the preset vehicle speed and the radar reflection time length of each lane to acquire a candidate vehicle length.
It can be understood that the intensities of the radar reflection signals reflected by the same candidate vehicle are similar, and the reflection time points corresponding to the radar reflection signals reflected by the candidate vehicle are also similar, so that a radar reflection signal set belonging to the same candidate vehicle can be determined according to the intensities of the reflection signals and the reflection time points.
It should be noted that the lane to which the candidate vehicle belongs may be determined based on a time difference between a transmission time point of the radar signal and a reception time point of the radar reflection signal, and it is understood that the farther the lane is located from the radar device, the longer the distance traveled by the radar signal when the radar signal is reflected, and thus the greater the time difference between the corresponding transmission time point of the radar signal and the reception time point of the radar reflection signal, and the lane to which the candidate vehicle belongs may be determined based on the time difference. Therefore, the radar device can not only count the number of passing vehicles in the lanes adjacent to the radar device, but also count the number of passing vehicles in the lanes separated from the radar device.
The radar reflection time length of the radar reflection signal set can be determined according to the first reflection time point and the last reflection time point in the reflection signal set, and the vehicle length of the candidate vehicle can be obtained by performing product operation on the radar reflection time length and a preset vehicle speed, wherein the preset vehicle speed can be obtained in various manners, and in an optional implementation manner, the average vehicle speed of the road section can be used as the preset vehicle speed.
For example, assuming that the reflected signal intensity of the reflection time point in the range of 1.8-2 seconds is 1, the radar reflected signal with the reflected signal intensity of 1 is taken as the radar reflected signal set of the candidate vehicle, the radar reflection time length is 0.2 seconds, and the preset vehicle speed is 15 meters per second, then the candidate vehicle length is 0.2 seconds multiplied by 15 meters per second, and the candidate vehicle length is 3 meters.
Step 603, counting the number of candidate vehicles with the candidate vehicle length greater than the preset length as a first number of passing vehicles.
It can be understood that, in some application scenarios, situations such as the electric bicycle reflecting radar reflected signals may occur, and in order to avoid the situations being counted into the first number, a preset length may be set, and candidate vehicles having a vehicle length greater than the preset length may be considered as vehicles, and then, the number of candidate vehicles having a vehicle length greater than the preset length is counted as the first number of passing vehicles.
For example, when there are 5 candidate vehicles, 2 of the candidate vehicles have vehicle lengths of 0.5 and 0.4 m, another 3 of the candidate vehicles have vehicle lengths of 2.4 m, 3 m and 2.8 m, and the preset length is 1 m, so that since the number of candidate vehicles having vehicle lengths greater than 1 m is 3, it is determined that the corresponding first number is 3.
And step 604, extracting the vehicle contour information in each candidate image frame, and screening out a target image frame containing complete vehicle contour information.
Step 605, determining a second number according to the vehicle contour information contained in the target image frame.
In the embodiment, the vehicle contour information can be extracted from each candidate image frame based on a deep learning technology, and it can be understood that at least one complete vehicle contour is not captured in some candidate image frames, so that at least one complete vehicle contour information is not included in the vehicle contour information extracted based on such candidate image frames; at least one complete vehicle contour is shot in some candidate image frames, so that the vehicle contour information extracted based on the candidate image frames comprises at least one complete vehicle contour information, and the image frames comprising at least one complete vehicle contour information are used as target image frames.
Further, the second number is determined based on vehicle contour information contained in the target image frame. In an alternative embodiment, a yolo (young Only Look one) algorithm may be used to obtain the corresponding second number according to the target image frame.
In some application scenarios, lane division may also be obtained according to a target image frame, specifically, the target image frame is subjected to binarization processing to perform color classification, if white intervals in the color classification are regularly arranged, the white area is considered as a boundary of the lane, and the lane is divided according to the white area, for example: if the number of lanes in the driving direction of the vehicle is 2, wherein the left lane is a straight lane or a left-turn lane, and the right lane is a right-turn lane; if the number of lanes in the driving direction of the vehicle is 3, wherein the left lane is a straight lane or a left-turn lane, the middle lane is a straight lane, and the right lane is a right-turn lane; if the number of lanes in the driving direction of the vehicle is 4, the left lane is a straight lane or a left-turn lane, the two middle lanes are straight lanes, and the right lane is a right-turn lane.
And 606, screening at least one candidate magnetic flux belonging to a preset magnetic flux range from the plurality of magnetic fluxes, and determining a pressure value corresponding to the candidate magnetic flux.
Step 607, determining the target sampling frequency of the pressure value larger than the preset pressure value, and determining the number of the target sampling frequencies to be the third number.
It is understood that, since the conductor passing through the geomagnetic induction and pressure device may be an electric bicycle, a pedestrian carrying metal, a vehicle, or the like, and since the conductors are different, the magnetic fluxes generated by the movement of the conductor may be different, in the present embodiment, in order to exclude other conductors than the vehicle, a magnetic flux range may be preset, and at least one candidate magnetic flux belonging to the preset magnetic flux range may be screened out among the plurality of magnetic fluxes.
In order to further avoid misjudging the bicycle, the electric bicycle and the like as the vehicle, the pressure value corresponding to the candidate magnetic flux can be determined, and a third number of passing vehicles is determined according to the magnetic flux and the corresponding pressure value thereof, wherein the third number can be confirmed in various ways, and an optional implementation mode comprises the following steps:
setting an independent induction coil and a pressure sensor in each lane, wherein the magnetic flux generated by each induction coil and the pressure value generated by the pressure sensor both carry corresponding lane marks, when the magnetic flux variation in the induction coil is greater than the preset magnetic flux variation, acquiring the pressure variation of the pressure sensor corresponding to the induction coil, and if the pressure variation is also greater than the preset pressure variation, determining the sampling frequency corresponding to the magnetic flux variation and the pressure variation as a target sampling frequency, which also carries the lane marks, counting the number of the target sampling frequencies in the period, thereby determining the third number of the passing vehicles measured by the geomagnetic induction and pressure device.
And 103, determining the target number of passing vehicles in each lane in the current period according to the first number, the second number and the third number.
In the above steps, a first number of passing vehicles recorded by the radar means, a second number of passing vehicles recorded by the photoelectric means, and a third number of passing vehicles recorded by the geomagnetic induction and pressure means are acquired.
It can be understood that the target number of vehicles passing through each lane in the current cycle can be determined according to the number acquired by the three devices, the determination method of the target number is various, and may be designed according to application scenarios, and the present embodiment is not limited, and the following examples are illustrated:
in an optional implementation manner, variances of the first number, the second number, and the third number are calculated, whether the variance is greater than a preset number variance threshold is determined, if the variance is greater than the preset variance threshold, an average of the first number, the second number, and the third number is used as a target number, and if the variance is not greater than the preset variance threshold, a median of the first number, the second number, and the third number is used as the target number.
In another alternative embodiment, the target number is determined by judging the same number of the first number, the second number, and the third number, specifically, as shown in fig. 7, the method includes the following steps:
step 701, determining whether the first quantity, the second quantity and the third quantity are the same.
In step 702, if at least two of the first number, the second number, and the third number are the same, the same number is determined as the target number.
In step 703, if the first number, the second number, and the third number are different from each other, deleting a minimum value or a maximum value of the first number, the second number, and the third number, and calculating an average value of the remaining numbers as a target number.
In this embodiment, the first number, the second number, and the third number are determined, and if at least two of the numbers are the same, the same two numbers are considered to be accurate, so that the same numbers can be taken as the target numbers.
If the first number, the second number, and the third number are different from each other, in order to obtain an accurate number of passing vehicles, a maximum value or a minimum value of the first number, the second number, and the third number may be deleted, and a mean value of the remaining numbers is calculated as the target number. For example, if the first number is 10, the second number is 8, and the third number is 9, in one embodiment, the largest number of the three numbers is removed, the average value of 8 and 9 is 8.5, 8.5 may be used as the target number, or 8.5 may be further rounded up to 9, and 9 may be used as the target number; in another embodiment, the smallest 8 of the three numbers is removed, the average of 10 and 9 is 9.5, 9.5 may be used as the target number, or 9.5 may be further rounded up to 10, and 10 is used as the target number.
And 104, generating traffic control instructions according to the target quantity so as to control the vehicles on each lane to pass according to the traffic control instructions.
In this embodiment, traffic conditions may be determined based on the target quantity to generate traffic control instructions including, but not limited to, lane marker changes and/or traffic light control changes.
In an optional implementation manner, the target number may be analyzed, the number of passing vehicles corresponding to each lane is obtained, the number of passing vehicles corresponding to each lane is compared with a preset number threshold, a target lane larger than the preset number threshold is determined, and the traffic indicator is changed, so that traffic dispersion for the target lane is realized. For example, if there are three lanes, wherein the left lane is a left turn lane, the corresponding traffic indicator is a left turn; the right lane is a right-turn lane, and the corresponding traffic indication sign is a right turn; the middle lane is a straight lane, and the corresponding traffic indication sign is straight. If the number of the vehicles corresponding to the middle lane is larger than the preset number threshold, the number of the vehicles passing through the middle lane is excessive, so that the traffic indication sign corresponding to the right lane can be changed from right turn to right turn straight, namely, the vehicles in the lane are allowed to go straight or turn right, and the passing pressure of the middle lane is reduced.
In another optional implementation manner, the determining the time length of the traffic signal lamp according to the difference between the target number and the preset number specifically includes:
and judging the difference between the target quantity and the preset quantity, namely in the embodiment, the preset quantity can represent the quantity of the passing vehicles adapted to the current passing signal lamp time length, and in order to judge whether the current passing signal lamp time length is adapted to the target quantity of the current passing vehicles, the difference between the target quantity and the preset quantity is further judged.
And if the difference is larger than the preset difference threshold, inquiring a preset database to obtain the passing delay time matched with the difference.
The passage delay time length can be calibrated according to experimental data.
And finally, prolonging the time length of the traffic signal lamp of each lane according to the traffic time length.
In this embodiment, if the difference is greater than the preset difference threshold, it indicates that the difference between the target number of the vehicles passing by currently and the preset number adapted to the current traffic signal lamp is large, and therefore the lamp length of the traffic signal lamp of the lane needs to be adjusted, and the corresponding relationship between the difference and the traffic delay time length may be stored in the preset database, where the corresponding relationship may be calibrated according to experience and/or experiment. Furthermore, the preset database can be queried according to the difference value between the target number and the preset number, and the time length of the same-row time delay matched with the difference value is obtained, so that the time length of the same-row signal lamp of each lane is prolonged according to the time length of the same-row signal lamp.
If the difference is not larger than the preset difference threshold, the time length of the same-row signal lamp of the current lane can be kept.

And 803, if the number of the second target vehicles is not greater than the preset number threshold, generating fault alarm information of the second target vehicle.
