Accordingly, it should be understood that those of ordinary skill in the art may make various changes and modifications to the embodiments described herein without departing from the scope and spirit of the present application. In addition, in order to explain clearly and concisely, descriptions of well-known functions and structures in the following description will be omitted.

1A is a structural schematic diagram of a traffic light data display system provided by an embodiment of the present application, and the traffic light display system includes a server 10 and a terminal device 20 .

The server 10 generates traffic light simulation data of a target traffic light installed at a target intersection;

the server 10 determines, according to the traffic light simulation data, the traffic light sharing data of the current time;

the server 10 transmits the traffic light sharing data to the terminal device 20 located at the target intersection;

The terminal device 20 displays the traffic light shared data.

The terminal device 20 may be a mobile terminal device such as a mobile phone or a tablet, or may be a vehicle-mounted terminal device.

The traffic light simulation data may be understood as data obtained by simulating and restoring standard traffic light data generated by a target traffic light.

The traffic light includes at least one of a car traffic light, a turn signal light, a lane traffic light, and a road and railway flat intersection signal light.

In addition, traffic lights corresponding to different driving directions may be installed at one intersection, and a traffic light corresponding to the driving direction of the terminal device may be used as a target traffic light. Correspondingly, the server 10 generates a traffic light simulation signal of the target traffic light.

For example, the server 10 may determine a conversion rule of a standard traffic signal of a target traffic light, and generate traffic light simulation data of the target traffic light according to the conversion rule.

Optionally, the server 10 directly retrieves and obtains the conversion rule of the standard traffic signal such as the target traffic light from the server 10 local, other storage device related to the server 10, or the cloud, and according to the retrieved conversion rule, The subsequent generation of traffic light simulation data can be performed directly.

When the server 10 cannot know the conversion rule of the target traffic light in advance, it may determine the conversion rule of the target traffic light online, and may perform a subsequent traffic light simulation data generation operation according to the determined conversion rule, Improve the mechanism for generating simulation data.

In a selectable realization manner of the embodiment of the present application, the server 10 determines the conversion rule of the target traffic light on-line, according to the raw data of the target traffic light installed at the target intersection, by the server 10 of the raw data. It may be to determine the conversion rule.

The raw data may be obtained from the server 10 local, other storage devices related to the server 10, or the cloud. Typically, raw data of the target traffic light may be obtained from a data provider of the traffic light, or the server 10 may accumulate past traffic light data generated by the target traffic light within a past period and obtain it.

Optionally, the machine learning model may be built in advance, and the machine learning model may be trained with raw data of traffic lights of the same type of intersection, so that the machine learning model has the ability to determine transformation rules. Correspondingly, the server 10 inputs raw data of a target traffic light set at the target intersection into a trained machine learning model corresponding to an intersection of the same type as the target intersection, and according to the output of the model, the raw data Determine the conversion rules.

Also, the device for training the machine learning model may be the same as or different from the server 10 .

In order to reduce the initial investment for determining the transformation rule of the traffic light, and at the same time reduce the amount of data calculation for determining the transformation rule, optionally, the server 10 may statistic transformation period of the raw data, the transformation period is a single transformation and at least one of a period, a continuous conversion period, and a complex conversion period. Correspondingly, when the server 10 generates the traffic light simulation data of the target traffic light according to the conversion rule, the server 10 generates the traffic light simulation data of the target traffic light according to the conversion period. In order to match the generated traffic light simulation data with the target traffic light, before generating the traffic light simulation data, the clock of the server must be adjusted so that the clocks of the server and the target traffic light match. For example, the synchronization of the two clocks may be maintained in a manner of Global Positioning System (GPS) time synchronization or network time synchronization.

A single conversion period may be understood as only overlapping traffic light data segments of the same conversion period exist in the entire traffic light data, and the traffic light data segment determines a single conversion period according to the time length of each traffic light state. Taking the schematic diagram of the vehicle traffic light data shown in Fig. 1B as an example, the traffic light data is data corresponding to the conversion of a single conversion period. For example, at the intersection of a road segment with a stable vehicle flow, the traffic lights are activated alternately with green light for 20 seconds, yellow light for 5 seconds, and red light for 25 seconds.

The continuous conversion period may be understood as overlapping traffic light data segments having at least two conversion periods in the entire traffic light data, and traffic light data segments having different conversion periods appearing alternately. For each traffic light data segment, a corresponding single conversion period is determined according to the time length of the traffic light state in the segment, and according to the single conversion period of each traffic light data segment, a continuous conversion period of the entire traffic light data is determined. Taking the schematic diagram of the vehicle traffic light data shown in Fig. 1C as an example, the traffic light data is data conforming to the conversion of the continuous conversion period. For example, at an intersection on a road segment in which vehicle flow is relatively stable, traffic lights alternately operate at 20 seconds of green light, 5 seconds of yellow light, 25 seconds of red light, 60 seconds of green light, 5 seconds of yellow light, and 65 seconds of red light.

The nesting transformation period may be understood as overlapping traffic light data segments of at least two transformation periods in the entire traffic light data, and traffic light data segments of different transformation periods appearing redundantly in the corresponding nesting period; According to the nesting period of each traffic light data segment, the outer period of the whole traffic light data is determined. Taking the schematic diagram of the vehicle traffic light data shown in Fig. 1D as an example, the traffic light data is data corresponding to the conversion of the complex conversion cycle. For example, on high-congested road sections, every morning during rush hour and evening rush hour, traffic lights alternately turn on at 60 seconds green, 5 seconds yellow, and 65 seconds red; At different times of the day, traffic lights alternate between green light for 20 seconds, yellow light for 5 seconds, and red light for 25 seconds.

In addition, through the method of generating the traffic light simulation data, the server 10 directly or indirectly acquires the standard traffic light data collected from the collection device, and there is no need to transmit the standard traffic light data to the terminal device 20, so No data transfer time from device to server 10 is required. In addition, since the traffic light simulation data is consistent with the standard traffic light data, it can be the basis of the accuracy of the traffic light shared data subsequently received by the terminal device 20 .

The traffic light sharing data determined by the server 20 may include a traffic light state indicating the current state of the terminal device passing at the intersection, for example, it may be at least one of a color of a traffic light and a shape of a traffic light icon. Optionally, the traffic light sharing data may include a remaining time indicating a time difference between a current traffic light state and a next state change.

In a selectable realization manner of the embodiment of the present application, the server 10 according to the traffic light simulation data, determining the traffic light sharing data of the current time, the server 10 according to the traffic light simulation data, the target traffic light of the current time determine the state of the traffic light; The server 10 may be to generate the traffic light shared data including the traffic light state.

Specifically, the server 10 determines the traffic light state corresponding to the current time in the traffic light simulation data, and generates the traffic light shared data including the traffic light state.

In another selectable realization manner of the embodiment of the present application, the server 10 according to the traffic light simulation data, determining the traffic light sharing data of the current time, the server 10 according to the traffic light simulation data, the target traffic of the current time determine the traffic light state of the traffic light; the server 10 determines the remaining time according to the conversion rule of the traffic light state; The server 10 may generate the traffic light shared data including the remaining time of the traffic light state, or generate the traffic light shared data including the traffic light state and the remaining time of the traffic light state.

Specifically, the server 10 determines the traffic light state corresponding to the current time in the traffic light simulation data, and sets the determination result as the traffic light state of the target traffic light at the current time; the server 10 determines the difference between the current time and the start time of the traffic light state in this period, to determine the time that has already been continued; the server 10 determines the remaining time according to the difference between the length of time corresponding to the current traffic light state and the already-continued time during the conversion period; The server 10 generates the traffic light shared data including the remaining time of the traffic light state, or generates the traffic light shared data including the traffic light state and the remaining time of the traffic light state.

In addition, in order for the driver to easily know the specific location of the target traffic light, the server 10 may add a traffic light identifier of the target traffic light to the shared traffic light data transmitted to the terminal device 20 , for example, , may include at least one of information such as intersection information where the target traffic light is located, location direction and location information, and a traffic light number.

What is understandable is the traffic light shared data generated by processing the traffic light simulation data through the server 10, and the collection device replaces the standard traffic light data obtained by collecting the target traffic light to the terminal device 20 of the target intersection. By transmitting, there is no need for data transmission time from the collection device to the electronic device, reducing the data delay and improving the data transmission efficiency. At the same time, by subdividing the traffic light simulation data into those including at least one of the traffic light state and the remaining time of the traffic light state, the subsequent driving process of the terminal device 20 can be guided, and the basis of safe driving of the terminal device 20 is can be

In a selectable realization manner, the terminal device 20 located at the target intersection may be a terminal device within the area to which the target intersection belongs. The zone to which the target intersection belongs may be a circular zone, a rectangular zone, or other irregular zone.

a terminal device in the area to which the target intersection belongs is the target terminal device; Transmitting the traffic light shared data including at least one of the traffic light state and the remaining time of the traffic light state to each target terminal device. Correspondingly, after the target terminal device receives the traffic light sharing data, the target terminal device displays the traffic light sharing data on the navigation map so that the driver of the target terminal device can understand the situation of the traffic light at the intersection in advance, the situation of the traffic light to quickly adjust driving behavior and improve the overall traffic situation at intersections.

Optionally, the target terminal device displaying the shared traffic light data on the navigation map may be displaying the shared traffic light data in a relevant area of the location where the target traffic light is located on the navigation map. The relevant area may be a location where the target traffic light is located, and an area around the location where the target traffic light is located.

For example, when the navigation map is an AR (Augmented Reality) real-time navigation, the state of each traffic light may be displayed at a location where a target traffic light is located among the navigation map, and the surrounding area of the location where the target traffic light is located, e.g. For example, in the upper section, the remaining time of the current traffic light state can be displayed.

Optionally, the terminal device 20 may provide a driving suggestion to the driver or generate presentation information according to the traffic light shared data so that the driver can refer and use it.

Illustratively, the terminal device 20 estimates a time to arrive at the target intersection according to its own positioning information and driving speed; According to the estimated time, the traffic light condition and the remaining time of the traffic light condition, a driving suggestion is provided or the presentation information is generated.

The driving suggestion includes acceleration driving, deceleration driving, or speed maintenance, and the presentation information includes at least one of an expected arrival time, whether to wait for a red light, and a red light waiting time.

In a selectable realization manner of the embodiment of the present application, the server 10 transmits the traffic light sharing data to the terminal device 20 located at the target intersection by transmitting the traffic light sharing data to the terminal device 20 in real time, so that the terminal It may be displayed on the device 20 .

In order to prevent the server 10 from wasting resources by sending traffic light sharing data unnecessarily, in another selectable realization manner of the embodiment of the present application, the terminal device 20 sends a traffic light acquisition command to the server 10 transmit; The server 10 may transmit the traffic light sharing data to the terminal device 20 located at the target intersection in response to the traffic light acquisition command to be displayed on the terminal device 20 .

Optionally, the terminal device 20 sending the traffic light acquisition command to the server 10 may be triggered by the driver through a hardware button or knob inside the terminal device 20 . In order to avoid high cost investment due to hardware improvement of the terminal device 20, optionally, the terminal device 20 sends a traffic light acquisition command to the server 10, so that the driver can use the application (eg, navigation software) ) can also be triggered by touching the virtual button.

In order to reduce the manual operation of the driver and realize the automatic transmission of the traffic light acquisition command, the terminal device 20 optionally matches the recognized current road information in the area where it is located with the standard road information related to the positioning information of the target intersection. and if the matching is successful, it may transmit a traffic light acquisition command to the server 10 . The road information may include at least one of a road direction, a stop line position, and coordinates of an intersection center point.

Illustratively, the terminal device 20 collects image information of an area in which it is located through an image collecting device installed therein; The intersection, the intersection stop line, and the road driving direction are recognized in the image information, and the current road information including the road direction, the stop line position, and the intersection center point coordinates can be determined according to the image collection ratio. Correspondingly, the terminal device 20 searches for and determines a target intersection having the closest distance to the self-positioning information according to the self-positioning information; obtain standard road information related to the target intersection; matching the standard road information with the current road information recognized by the terminal device; If matching is successful, for example, if, as a result of comparison, the similarity is greater than a set similarity threshold, a traffic light acquisition command is transmitted to the server 10 .

The standard road information may be previously stored locally in the terminal device 20 , or in other storage devices related to the terminal device 20 or in the cloud. In order to more easily retrieve the standard road information, it is usually stored in association with the intersection identifier and the standard road information; Correspondingly, according to the intersection identifier of the target intersection, standard road information is retrieved and obtained.

In order to reduce the time delay according to the acquisition, execution, reception and response of the traffic light, in a selectable realization manner of the embodiment of the present application, the server 10 obtains the traffic light acquisition instruction sent by the terminal device 20, Until the transmission stop condition of the traffic light shared data is satisfied, the traffic light shared data is transmitted to the terminal device 20 according to the set frequency.

Illustratively, satisfying the transmission stop condition of the traffic light shared data is that this time the traffic light shared data transmission time of the server 10 reaches a set time threshold, or the server 10 is transmitted by the terminal device 20 It may be to receive a stop signal acquisition stop command. The set time threshold is set by a technician according to demand or experience, or determined by repeating many experiments.

Optionally, the terminal device 20 recognizes its own positioning information; If the self-positioning information deviates from the center point of the intersection of the target intersection is greater than the set distance threshold, it transmits a traffic light acquisition stop command to the server 10 . The set distance threshold is set by a technician according to demand or experience, or determined by repeating many experiments.

An embodiment of the present application generates traffic light simulation data of a target traffic light installed at a target intersection through a server; determine the current time traffic light sharing data according to the traffic light simulation data through the server; sending the traffic light sharing data to the terminal device located at the target intersection through the server; Display the traffic light shared data through the terminal device. The technical means introduces the traffic light simulation data of the target traffic light to the server, generates the traffic light shared data according to the traffic light simulation data, and replaces the transmission of the standard traffic light data of the target traffic light collected by the collection device, " As the data transmission method of the server-terminal device, it replaces the traditional data transmission method of “road measuring device—traffic police system—data provider—terminal device” or “road measuring device—data provider—terminal device”, The transmission link is reduced, the delay of data transmission is reduced, and the data transmission efficiency is further improved, and the real-time and accurate data reception by the target terminal device is ensured. In addition, by displaying the shared traffic light data on the terminal device, the driver of the terminal device can grasp the situation of the traffic light at the intersection in advance, so that the driving behavior can be quickly adjusted according to the situation of the traffic light, and the overall traffic condition of the vehicle at the intersection is improved do.

Based on each of the above technical means, in order to prevent the difference between the traffic light simulation data and the standard traffic light data due to causes such as failure, replacement, failure recovery or artificial control of the target traffic light, typically, the server 10 It is further necessary to receive the standard traffic light data of the traffic light, and determine the accuracy of the traffic light sharing data according to the standard traffic light data of the target traffic light.

Illustratively, the server 10 determines the correspondence between the standard traffic light data and the traffic light shared data of the target traffic light received in the past period, and according to the match determination result, the traffic light shared data to the terminal device 20 control the transmission.

Optionally, the server 10 compares the standard traffic light data at different times of the target traffic light received in the past period with the traffic light shared data of the corresponding time; if the comparison result of the first set quantity is consistent, obtaining a consistency determination result indicating that the data are identical; If the comparison result of the second set quantity does not match, a match determination result indicating that the data does not match is obtained. Each of the first set quantity and the second set quantity may be a fixed value determined by a technician according to demand or experience value, or a variable value determined according to the quantity of traffic light shared data generated in the past period, for example, It may be determined by multiplying the generated quantity by a set percentage. Alternatively, the first set quantity and the second set quantity may be determined by repeating many experiments.

Illustratively, if the standard traffic light data of the target traffic light received in the past period and the traffic light sharing data do not match, it may be that all standard traffic light data have not been received, for example, the target traffic light is broken, or There may be a situation where network packet loss has occurred; It may be that the standard traffic light data transmitted by the broken target traffic light has been received, for example, it may be a situation of restoring the target traffic light; The conversion period of the standard traffic light data accumulated in the past period and the standard traffic light data may be different, for example, it may be a situation in which traffic lights are artificially controlled.

Optionally, in the case of a coincidence determination result that the data match, that is, when the standard traffic light data of the target traffic light received in the past period and the traffic light sharing data match, the traffic light shared data is transmitted to the target terminal device located at the target intersection.

Or, optionally, in the case of a match determination result that the data do not match, that is, if the standard traffic light data of the target traffic light received in the past period and the traffic light sharing data do not match, the traffic light sharing data is sent to the target terminal device located at the target intersection. refuse to send

Traffic lights are often artificially controlled by traffic police during rush hours, for example, morning rush hour or evening rush hour. In preparation for the situation of temporarily adjusting the traffic light, in a selectable realization manner of the embodiment of the present application, the server 10 may introduce a reliability of the traffic light shared data, and control the transmission of the traffic light shared data.

Illustratively, the server 10 adjusts the reliability of the traffic light shared data according to the match determination result; when the reliability is less than the set reliability threshold, the server 10 prohibits transmitting the traffic light sharing data to the target terminal device located at the target intersection; When the reliability is greater than or equal to the set reliability threshold, the server 10 transmits the traffic light sharing data to the target terminal device located at the target intersection. The set reliability threshold may be determined by a technician according to demand or experience.

Specifically, if the standard traffic light data of the target traffic light received in the past period and the traffic light shared data do not match, the server 10 lowers the reliability of the traffic light shared data; When the standard traffic light data of the target traffic light received in the past period and the traffic light shared data match, the server 10 increases the reliability of the traffic light shared data. Optionally, the extent to which the reliability is adjusted may be determined by the technician according to needs or experience values. The specific values of the height and lowering width may be the same or different.

It is understandable that, in order to easily control the transmission of data, the reliability is usually set to a fixed interval, for example, the reliability interval may be [0, 1], and the adjusted reliability is not limited to the range of the reliability interval. If it deviates, the boundary value adjacent to the adjusted reliability is taken as the final reliability. In general, in order to easily control data transmission, the reliability is directly adjusted to 0 to lower the reliability, and the reliability is directly adjusted to 1 to increase the reliability.

After prohibiting the transmission of the traffic light sharing data to the target terminal device located at the target intersection based on each of the above technical means, the server 10 returns to the past standard traffic light data corresponding to a time when the reliability is lower than the set reliability threshold. Accordingly, a transformation rule is determined, and further, according to the determined transformation rule, the traffic light simulation data of the target traffic light is adjusted, thereby laying the foundation for the integrity of the traffic light sharing data in the life cycle of the target traffic light.

An embodiment of the present application determines the correspondence between the standard traffic light data and the traffic light shared data of the target traffic light received in the past period, in the operation of the server performing the sending of the traffic light shared data; According to the match determination result, it is subdivided into an operation to control the transmission of the traffic light shared data to the target terminal device. Prevent situations from occurring, and improve the accuracy of traffic light sharing data.

Each traffic light data display method and traffic light data display device provided by the embodiment of the present application is a method in which the server 10 of the traffic light data display system transmits the traffic light data of the traffic light to the terminal device 20 in the field of intelligent traffic technology. applies to the situation. Each traffic light data display method is performed by a traffic light transmitting device, which is implemented in software and/or hardware, and is specifically arranged in an electronic device.

2 is a flowchart of a traffic light data display method provided by an embodiment of the present application, the method is applied to the server 10, and specifically includes the following steps.

In step S201, the traffic light simulation data of the target traffic light installed at the target intersection is generated.

The traffic light simulation data may be understood as data obtained by simulating and restoring standard traffic light data generated by a target traffic light.

The traffic light includes at least one of a car traffic light, a turn signal light, a lane traffic light, and a road and railway flat intersection signal light.

In addition, traffic lights corresponding to different driving directions may be installed at one intersection, and a traffic light corresponding to the driving direction of the terminal device may be used as a target traffic light. Correspondingly, a traffic light simulation signal of a traffic light in the driving direction of the terminal device is generated.

For example, it is possible to determine a conversion rule of a standard traffic signal of a target traffic light, and generate traffic light simulation data of the target traffic light according to the conversion rule.

Optionally, directly from the electronic device local, other storage device related to the electronic device, or the cloud, directly retrieving and obtaining a conversion rule of a standard traffic signal of a target traffic light, and according to the retrieved conversion rule, generating subsequent traffic light simulation data can be performed directly.

When the conversion rule of the target traffic light is not known in advance, the conversion rule of the target traffic light may be determined online, and subsequent generation of traffic light simulation data may be performed according to the determined conversion rule, so that the generation mechanism of the traffic light simulation data to improve

In a selectable realization manner of the embodiment of the present application, the online determining of the conversion rule of the target traffic light may be determining the conversion rule of the raw data according to the raw data of the target traffic light installed at the target intersection.

The raw data may be obtained from a local electronic device, or from other storage devices related to the electronic device or from the cloud. Typically, raw data of the target traffic light is obtained from a data provider of the traffic light; The electronic device may accumulate and acquire past data of a target traffic light within a past period.

Optionally, the machine learning model may be built in advance, and the machine learning model may be trained with raw data of traffic lights of the same type of intersection, so that the machine learning model has the ability to determine transformation rules. Correspondingly, raw data of a target traffic light installed at a target intersection is input to a trained machine learning model corresponding to an intersection of the same type as the target intersection, and a conversion rule of the raw data is determined according to the output result of the model .

In order to reduce the initial investment in determining the transformation rule of the traffic light, and at the same time reduce the amount of data calculation for determining the transformation rule, optionally, the transformation period of the raw data may be statistically calculated, the transformation period is: a single transformation period, a continuous transformation period and at least one of a complex transformation period; Correspondingly, generating the traffic light simulation data of the target traffic light according to the conversion rule may be generating the traffic light simulation data of the target traffic light according to the conversion period.

It is understandable that, through the method of generating the traffic light simulation data, there is no need to directly or indirectly transmit the standard traffic light data collected by the electronic device to the collecting device, so that there is no need for data transmission time from the collecting device to the electronic device. In addition, since the traffic light simulation data is consistent with the standard traffic light data, it can be the basis of the accuracy of the traffic light shared data subsequently received by the terminal device.

In step S202, according to the traffic light simulation data, the current time traffic light sharing data is determined.

In step S301, the traffic light simulation data of the target traffic light installed at the target intersection is generated.

In step S302, according to the traffic light simulation data, the current time traffic light sharing data is determined.

In step S303, the correspondence between the standard traffic light data of the target traffic light received in the past period and the traffic light shared data is determined.

In order to prevent the difference between the traffic light simulation data and the standard traffic light data due to causes such as failure, replacement, failure recovery, or artificial control of the target traffic light, in general, by receiving the standard traffic light data of the target traffic light, According to the standard traffic light data, the accuracy of the traffic light shared data should be judged.

Optionally, compare the standard traffic light data at different times of the target traffic light received in the past period with the traffic light shared data of the corresponding time; if the comparison result of the first set quantity is consistent, obtaining a consistency determination result indicating that the data are identical; If the comparison result of the second set quantity does not match, a match determination result indicating that the data does not match is obtained. Each of the first set quantity and the second set quantity may be a fixed value determined by a technician according to a demand or experience value, or a variable value determined according to the quantity of traffic light shared data generated in the past period, for example, traffic light shared data It may be determined by multiplying the generated quantity and a set percentage. Alternatively, the first set quantity and the second set quantity may be determined by repeating many experiments.

Illustratively, if the standard traffic light data of the target traffic light received in the past period and the traffic light sharing data do not match, it may be that all standard traffic light data have not been received, for example, the target traffic light is broken, or There may be a situation where network packet loss has occurred; It may be that the standard traffic light data transmitted by the broken target traffic light has been received, for example, it may be a situation of restoring the target traffic light; The conversion cycle of the standard traffic light data accumulated in the past period and the traffic light shared data may be different, for example, it may be a situation in which traffic lights are artificially controlled.

The specific values of the height and lowering width may be the same or different.

It is understandable that, in order to easily control the transmission of data, the reliability is usually set to a fixed interval, for example, the reliability interval may be [0, 1], and the adjusted reliability is not limited to the range of the reliability interval. If it deviates, the boundary value adjacent to the adjusted reliability is taken as the final reliability. In general, in order to easily control data transmission, the reliability is directly adjusted to 0 to lower the reliability, and the reliability is directly adjusted to 1 to increase the reliability.

Based on the respective technical means, after prohibiting the transmission of the traffic light sharing data to the target terminal device located at the target intersection, the conversion rule is determined according to the past standard traffic light data corresponding to the time when the reliability is lower than the set reliability threshold Further, according to the determined conversion rule, the traffic light simulation data of the target traffic light is adjusted, thereby providing a basis for the integrity of the traffic light sharing data in the life cycle of the target traffic light.
