[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0050] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0051] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a traffic signal control method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0052] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as a computer program corresponding to a traffic signal control method in an embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0054] In this embodiment, a traffic signal control method is provided, which is applied to a shared vehicle for traffic control, wherein the shared vehicle is provided with a traffic signal device. Figure 2 is a flow chart of a traffic signal control method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0055] Step S202, obtaining traffic flow information of a target area and vehicle distribution information of the shared vehicle in the target area through an information collection device, wherein the target area is determined after the information collection device collects initial traffic information of the initial area and divides the initial area into GIS areas, and the vehicle distribution information includes location information, equipment information, and usage frequency information of the shared vehicle;

[0056] In this embodiment, after the initial area is divided into GIS areas, the traffic flow information of the target area is accurately distributed, so that subsequent traffic control and vehicle calls can be calculated more accurately, thereby improving control accuracy; and the reason for GIS area division is to reduce the interference of traffic information between different areas, thereby improving calculation accuracy.

[0057] Among them, the information collection device includes (but is not limited to) visible light cameras, infrared cameras, lidars, millimeter wave radars or their combinations and other devices or equipment that can collect traffic flow information. The target area includes (but is not limited to) areas without traffic lights such as street intersections where traffic control is required. The initial area includes (but is not limited to) all areas where traffic flow information is collected. For example, the initial area is a city, and the target area is a street intersection in the city; correspondingly, the traffic flow information includes but is not limited to historical traffic information of the target area, traffic information in the target time period, historical accident frequency, historical accident events and other information. It can be imagined that after obtaining historical information such as historical traffic information, a preset spatiotemporal prediction model can be used to predict traffic for a certain time period in the future, and the prediction results can be used as part of the traffic flow information; shared vehicles include but are not limited to shared bicycles, shared electric vehicles and other shared vehicles.

[0058] It should be noted that in addition to location information, equipment information and frequency information, vehicle distribution information can also include shared vehicle ID information, age, model, traffic control frequency, maximum movement speed and other information; flow information includes (but is not limited to) the flow of motor vehicles, non-motor vehicles, pedestrians, pedestrian groups and other objects.

[0059] It is easy to imagine that to realize the traffic control function, the traffic control device can be but not limited to equipment such as vehicle-mounted traffic lights.

[0060] Step S204, when it is determined that the traffic flow information meets the first threshold, target determination calculation is performed on the location information, the device information, and the usage frequency information in sequence to obtain a target calculation result, and a target vehicle is determined according to the target calculation result;

[0061] In this embodiment, when the traffic flow is greater than the first threshold, a shared vehicle near the target area is selected or dispatched to the target area to conduct traffic directing, thereby timely directing traffic in the target area, reducing traffic congestion, and improving traffic directing efficiency; at the same time, there is no need to arrange manual traffic directing, thereby reducing health damage to traffic control personnel.

[0062] The first threshold includes but is not limited to the total flow value of one or more objects such as motor vehicles, non-motor vehicles, pedestrians, etc. in the target area within a unit time. It should be noted that the calculation of the first threshold is obtained by predicting and calculating the historical flow data of the target area through the prediction model. In addition to calculating the historical flow information, the process also needs to include road information (such as width, direction, lane division, etc.) as a condition into the calculation.

[0063] Step S206, generating a target movement route based on the traffic flow information, and sending the target movement route and a movement instruction to the target vehicle to instruct the target vehicle to move to the target area along the target movement route;

[0064] In this embodiment, after the target motion route is generated, it is possible to determine whether the vehicle is running normally based on whether the vehicle moves along the target motion route, thereby achieving effective monitoring of the vehicle.

[0065] It should be noted that in order to realize the vehicle's self-movement to the target area, in addition to generating the target movement route, real-time tracking equipment (such as the Beidou system, GPS positioning system, etc.) and image acquisition and processing systems for real-time photography and identification of the road surface are also required. Therefore, positioning communication equipment and image processing equipment are usually required. In order to improve data transmission capabilities, multiple data transmission base stations can be set up in the target area, or relevant equipment can be carried by the vehicle itself.

[0066] Step S208: upon receiving the area arrival information fed back by the target vehicle, sending a signal control instruction to the traffic signal device to instruct the traffic signal device to perform traffic signal conversion based on the traffic flow information.

[0067] In this embodiment, traffic command is achieved by having the traffic signal device change the corresponding traffic signal to reduce manual participation, thereby reducing problems such as personal injury and command errors caused by manual command. At the same time, since the signal conversion process is based on data calculation, the command effect can also be made more accurate, further improving the efficiency of traffic command.

[0068] Among them, the area arrival information includes the arrival location coordinates, image information of surrounding buildings, etc. In order to enhance the accuracy of the area arrival information, the area arrival information should be identified and judged through the corresponding image algorithm or recognition model to avoid sending erroneous signal control instructions.

[0069] It should be noted that in order to achieve control over the traffic signal device, communication data such as the communication ID of the traffic signal device should be stored in advance. At the same time, the communication equipment near the target area can be temporarily used as a communication device for signal transmission and control of the traffic signal device, thereby reducing the equipment load of the vehicle itself.

[0070] Through the above steps, shared vehicles conduct traffic control in the target area, which reduces manual participation, solves the problem of low traffic control efficiency, and improves traffic control efficiency.

[0071] The execution subject of the above steps may be a base station, a mobile terminal, etc., but is not limited thereto.

[0072] In an optional embodiment, after the information collection device collects initial traffic information for the initial area, dividing the initial area into GIS areas includes:

[0073] Step S2022, obtaining the GIS information collection range information of the information collection device and the preset grid information of the initial area;

[0074] Step S2024, performing a first intersection calculation on the GIS information collection range information and the preset grid information, determining a first intersection area between the information collection range information and the preset grid information, and using the first intersection area as the target area.

[0075] In this embodiment, after obtaining the target area, the flow information and area within the preset grid collected by the information collection device can be averaged, and the result can be used as the traffic flow information of the target first intersection area. This is because after GIS area division, the target area can be used as part of the grid area, and it is also part of the range of the information collection device. At this time, averaging can avoid interference from information outside the area and reduce the amount of calculation, thereby improving calculation efficiency and accuracy.

[0076] It should be noted that in the process of flow averaging, the ratio of the target area to the grid area can be determined first, and then the ratio is multiplied by the flow information within the information collection range, and the calculated value is used as the traffic flow information of the target area.

[0077] Among them, the GIS information collection range information includes the information collection range area, boundary coordinates, etc. of the information collection device, and correspondingly, the preset grid information includes the grid-shaped area boundary coordinates, area, etc. after the initial area is gridded.

[0078] In an optional embodiment, when it is determined that the traffic flow information satisfies a first threshold, performing target determination calculations on the location information, the device information, and the usage frequency information in sequence to obtain a target calculation result, and determining the target vehicle according to the target calculation result includes:

[0079] Step S2042, when it is determined that the traffic flow information meets the first threshold, calculating the distance data between the shared vehicle in the target area and the target area based on the location information;

[0080] Step S2044, when it is determined that the device information meets the first usage condition, the target vehicle is determined according to the usage frequency information and the distance data.

[0081] In this embodiment, the distance data is calculated to determine the shared vehicle closest to the target area, thereby ensuring that the shared vehicle can realize movement and traffic command functions. The equipment information is used to determine that all equipment of the shared vehicle is in normal condition. The frequency of use information is used to ensure that the vehicle is not used frequently in the target area, thereby avoiding affecting the user's travel efficiency.

[0082] In an optional embodiment, before sending a signal control instruction to the traffic signal device to instruct the traffic signal device to perform a traffic signal change based on the traffic flow information when receiving the area arrival information fed back by the target vehicle, the method further includes:

[0083] Step S20802: acquiring the motion information of the target vehicle through the vehicle-mounted device, wherein the motion information includes the motion direction, motion speed, motion position, and body swing amplitude of the target vehicle, so as to perform at least one of the following operations:

[0084] The image information collected by the vehicle-mounted camera device and the vehicle body swing amplitude obtained by the vehicle-mounted level meter are used to calibrate the swing amplitude of the vehicle body to obtain a calibration result; when the calibration result meets the amplitude condition, a power adjustment instruction is sent to the power system of the target vehicle to adjust the movement speed;

[0085] Performing a direction calibration operation on the movement direction through image information collected by the vehicle-mounted camera device and preset road image information;

[0086] Based on the movement position and the target movement route, a direction calibration operation is performed on the movement direction.

[0087] In this embodiment, the swing amplitude of the shared vehicle is adjusted to ensure that the shared vehicle does not roll over during operation, so that it can move safely to the target area; and the movement direction is calibrated through road image information to ensure that the shared vehicle moves along a predetermined route, so as to achieve accurate monitoring of the shared vehicle, and at the same time, it can also be determined whether the shared vehicle is stolen by judging whether the road image information meets expectations, thereby playing an anti-theft role; similarly, calibration through movement position and target movement route is also to determine whether the shared vehicle is operating normally.

[0088] In an optional embodiment, the image information collected by the vehicle-mounted camera device and the vehicle body swing amplitude obtained by the vehicle-mounted level meter, and the swing amplitude of the vehicle body are calibrated to obtain the calibration result, which includes:

[0089] Step S208022, acquiring the image information and the swing amplitude of the vehicle body;

[0090] Step S208024, performing information recognition on the image information through a first image model to obtain first amplitude information of the target vehicle;

[0091] Step S208026, performing amplitude calibration calculation on the body swing amplitude and the first amplitude information to obtain a calibration result;

[0092] Step S208028: When the calibration result satisfies the amplitude condition, a power adjustment instruction is sent to the power system.

[0093] In this embodiment, during the calibration process, the information of image recognition is compared with the amplitude detected by the vehicle-mounted level meter in order to ensure that the amplitude finally obtained is more accurate and improve the detection accuracy.

[0094] It should be noted that the first image model can be an image recognition model such as yolo5.

[0095] In an optional embodiment, upon receiving the area arrival information fed back by the target vehicle, sending a signal control instruction to the traffic signal device to instruct the traffic signal device to perform traffic signal conversion based on the traffic flow information includes:

[0096] Step S20822, calculating target traffic information within a first time limit through a first spatiotemporal model according to the traffic flow information;

[0097] Step S20824, when the target flow information meets the third threshold, sending a first signal control instruction to the traffic signal to instruct the traffic signal device to extend the duration of the red light signal;

[0098] Step S20826: When the target flow information does not meet the third threshold, a second signal control instruction is sent to the traffic signal to instruct the traffic signal device to change the traffic signal according to the normal duration.

[0099] In this embodiment, when obtaining historical traffic, it is necessary to judge the traffic conditions in a certain time period in the future, so as to adjust the traffic control strategy in time and improve the traffic control efficiency.

[0100] Among them, the third threshold can be the flow situation of preset vehicles, pedestrians and other target objects passing through the target area within a unit time, and the change of traffic signals includes but is not limited to changing the red light, yellow light and green light in sequence; the first spatiotemporal prediction model includes a similit model for spatiotemporal recognition.
