By calling the information of the terminal background acceleration sensor such as a mobile phone, referring to the current actual position of the vehicle, and based on whether the vehicle is from static to start, it is inferred whether it is waiting for the red and green light at the intersection, so as to calculate the lighting period of the signal light and output, so as to realize the signal light countdown function for users.

[0028] Exemplary embodiments of the present disclosure are described herein with reference to the accompanying drawings, in which various details of the embodiments of the present disclosure are set forth to facilitate an understanding, and should be considered in a descriptive sense. It will be readily appreciated that various modifications and changes can be made to the embodiments described herein without departing from the scope and spirit of the disclosure. Likewise, the present disclosure is not to be limited to the details of the description, and the accompanying drawings, as the spirit and scope of the disclosure are to be limited only by the appended claims.

[0029] For better understanding, the following explains some related concepts that can be involved in the embodiments of the present disclosure.

[0030] It can be understood that a signal lamp is changed according to a rule set in advance in a cycle. In the related art, some map navigation applications can provide a signal lamp countdown function for a user based on the lighting principle of a signal lamp. First, the application calls information of a phone background acceleration sensor, and refers to a current actual position of a vehicle. Then, whether the user is waiting for a red light at an intersection is inferred by judging whether the vehicle is started from a static state. After the conclusion is made, the navigation application can count the number of vehicles passing the red light and the time interval of starting the vehicle in a time period. After the data is put into the same coordinate system, it is found that they have a regular change like a sine curve. Finally, the periodic change rule of the signal lamp can be obtained through simple processing on an algorithm, so that the signal lamp countdown function can be provided for the user.

[0031] However, the algorithm "prediction" of the navigation application relies on user data, resulting in certain limitations of the signal light countdown function provided by the navigation application. For example, some intersections have few people passing through, and the navigation application can obtain less data. This results in insufficient data to support algorithm prediction, or inaccurate signal light countdown function.

[0032] The present disclosure provides a signal light data processing method, which can solve the problem of inaccurate signal light countdown function predicted by the navigation application in the related art. The signal light data method provided by the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings.

[0033] Please refer to Figure 1 , Figure 1 is a flowchart of a signal light data processing method provided by an embodiment of the present disclosure, as shown in Figure 1 The method comprises the following steps:

[0034] Step S101, acquiring first signal light data of a target intersection.

[0035] The first signal light data comprises a timestamp, a signal light color of at least one phase, and first countdown information corresponding to each of the signal light colors of the at least one phase.

[0036] It should be noted that the method provided by the embodiments of the present disclosure can be applied to a server including a police network, a traffic management platform, a municipal service platform including a police network and a government network, and the like. Alternatively, in subsequent embodiments, the method is applied to the above-mentioned servers as an example to describe the signal light data processing method provided by the present disclosure.

[0037] For example, the server acquires first signal light data of a target intersection. The target intersection can be any intersection provided with a signal light, including but not limited to a cross intersection, a "T" intersection, a herringbone intersection, and the like. It can be understood that the number of signal lights of the target intersection can be related to its type, for example, a cross intersection usually includes four signal lights. In the embodiments of the present application, the first signal light data of the target intersection can refer to the data of all signal lights of the target intersection, for example, when a cross intersection includes four signal lights, the first signal light data of the intersection also includes the respective signal light data of the four signal lights.

[0038] In the embodiment of the present application, the first signal lamp data includes a timestamp, which can be time information of generation of the first signal lamp data. For example, the timestamp can be the time when a certain signal lamp color starts to light. In the first signal lamp data, each signal lamp color of each phase has a corresponding timestamp, that is, the first signal lamp data can include the time when each signal lamp color of each phase starts to light.

[0039] It should be noted that, at a signal lamp controlled intersection, each control state (one right of way), that is, the combination of different lamp colors displayed for different directions of various approaches, is called a signal lamp phase. The signal lamp phase is also the corresponding release time given to the traffic flow in different directions of the intersection. For example, taking a cross intersection as an example, the traffic flow directions of the cross intersection usually include straight, left turn (U-turn) and right turn, and four intersections combined with the three traffic flow directions can be divided into four groups: (1) east-west straight: east-west, west-east; (2) north-south straight: south-north, north-south; (3) east-west left turn: east-south, west-north; (4) north-south left turn: north-east, south-west; the four groups can be controlled by four groups of signal lamps, that is, four different phases, and the signal lamp of the intersection includes four phases. Each phase includes at least one signal lamp color, for example, usually red, green and yellow. Taking the east-west straight as an example, the phase includes the red, green and yellow light time of the east-west and west-east two groups of signal lamps.

[0040] In the embodiment of the present application, the first signal lamp data includes first countdown information corresponding to each signal lamp color of at least one phase of the target intersection signal lamp. For example, taking the east-west straight corresponding phase of the four phases of the above cross intersection as an example, the east-west straight corresponding phase includes the east-west and west-east two groups of signal lamps, each group of signal lamps includes first countdown information of red light, first countdown information of green light and first countdown information of yellow light, wherein the first countdown information of yellow light can not be counted.

[0041] It can be understood that the light time and light cycle of the signal lamp of the intersection are usually set or controlled by the police special network, and the method provided in the embodiment of the present application is applied to a server including the police special network, so that the server can obtain the first signal lamp data of the target intersection through the police special network, and can obtain the timestamp of the signal lamp data, the signal lamp color of at least one phase of the target intersection and the first countdown information corresponding to each signal lamp color of the at least one phase.

[0042] In step S102, time delay compensation information is determined according to the current time information and the timestamp.

[0043] It should be noted that the server may determine the time delay compensation information according to the current time information and the time stamp carried by the first signal lamp data in the process of obtaining the first signal lamp data through the traffic police private network. For example, the current time information obtained by the server is 8:10:35, and the time stamp carried by the first signal lamp data is 8:10:33, and there is a time delay of 2s between them, and the time delay compensation information is determined according to the current time information and the time stamp. 2s.

[0044] In step S103, the first countdown information is adjusted based on the time delay compensation information to obtain the second signal lamp data of the target intersection.

[0045] The second signal lamp data includes the signal lamp color of the at least one phase and the second countdown information corresponding to the signal lamp color of the at least one phase.

[0046] In the embodiment of the application, after the server determines the time delay compensation information according to the current time information and the time stamp, the first countdown information is adjusted based on the time delay compensation information to obtain the second countdown information. For example, assuming that the time delay compensation information is 2s, that is, the first countdown information is 2s behind, the first countdown information needs to be reduced by 2s to obtain the second countdown information, so that the second countdown information can match the current time information, thereby ensuring the accuracy of the second countdown information.

[0047] It should be noted that in the embodiment of the application, each phase has a corresponding time stamp for each signal lamp color, and the server can calculate the time delay compensation information for each signal lamp color in each phase based on the current time information and the time stamp corresponding to each signal lamp color in each phase. Then, the first countdown information corresponding to each signal lamp color in each phase is adjusted to obtain the second countdown information, thereby ensuring the accuracy of the second countdown information corresponding to each signal lamp color in each phase, and thereby ensuring the accuracy of the countdown information of each signal lamp color of the target intersection.

[0048] In step S104, the second signal lamp data is sent to the terminal.

[0049] It can be understood that the server can send the second signal lamp data to the terminal, and the second signal lamp data includes the adjusted second countdown information of each signal lamp color in each phase of the target intersection, and the second countdown information obtained by the terminal is more accurate, which is more helpful for the application of the second signal lamp data by the terminal.

[0050] Optionally, the terminal can output the second signal lamp data, for example, can display or broadcast the signal lamp color and the second countdown information corresponding to the signal lamp. The terminal includes but is not limited to devices or software such as a navigation application, a vehicle, a vehicle service platform, a recorder, etc.

[0051] The technical solution provided by the embodiments of the present disclosure is that a server acquires first signal lamp data of a target intersection, the first signal lamp data includes a timestamp, the server determines time delay compensation information according to current time information and the timestamp, and then adjusts the first countdown information of each signal lamp color in each phase in the first signal lamp data based on the time delay compensation information to obtain second countdown information of each signal lamp color in each phase, and sends the second signal lamp data including the second countdown information to a terminal. In the embodiments of the present disclosure, the server determines the time delay compensation information through the current time information and the timestamp, and then adjusts the first countdown information of the signal lamp based on the time delay compensation information, which takes into account the transmission time delay that may exist in the transmission process of the signal lamp data. In this way, it can be ensured that the adjusted second countdown information can match the actual countdown information of the signal lamp at the target intersection, so as to ensure that the second countdown information is synchronized with the actual countdown information of the signal lamp at the target intersection, and the accuracy of the second countdown information acquired by the terminal is guaranteed, which is more helpful for the application of the signal lamp data in the terminal.

[0052] Compared with the way in which the navigation application predicts the countdown information of the signal lamp by acquiring user data, the scheme provided by the present disclosure can effectively avoid the problem of inaccurate countdown caused by limited user data. The scheme provided by the present disclosure processes the signal lamp data through a server including a police network, which can ensure the sufficiency of the signal lamp data and effectively guarantee the accuracy of the second countdown information obtained after adjustment, so that the second countdown information is synchronized with the actual countdown information of the signal lamp at the target intersection.

[0053] Optionally, before the step S101, the method further includes:

[0054] acquiring original signal lamp data of the target intersection and time information of generating the original signal lamp data;

[0055] performing data processing on the original signal lamp data according to a data format of the original signal lamp data to obtain the first signal lamp data;

[0056] determining the timestamp of the first signal lamp data according to the time information of generating the original signal lamp data.

[0057] It should be noted that the data format of the signal lamp data can be related to the manufacturer of the signal lamp or the model of the signal lamp. For example, the data format of the signal lamp data of different manufacturers or different models of signal lamps can be different. For example, the data format of some signal lamp data is lamp color + countdown information, the data format of some signal lamp data is phase + lamp color, the data format of some signal lamp data is lamp color phase number, etc. In the embodiment of the present disclosure, the original signal lamp data refers to signal lamp data that has not been processed and can have different data formats.

[0058] In the embodiment of the present disclosure, after obtaining the original signal lamp data of the target intersection, the server can process the original signal lamp data into first signal lamp data with a unified data format, which can be a format preset by the server. In this way, the server can process the original signal lamp data obtained in different data formats into first signal lamp data with a unified data format, so as to facilitate the subsequent identification and processing of the first signal lamp data by the server.

[0059] It should be noted that when the server obtains the original signal lamp data of the target intersection, it can also obtain the time information of the original signal lamp data. The time information can refer to the generation time of the countdown of each signal lamp color in each phase of the target intersection, for example, the generation time of the countdown of the green light for east-west straight traffic at the target intersection is 8:10:10. After converting the original signal lamp data into first signal lamp data, the time information is determined as the timestamp of the green light for east-west straight traffic at the target intersection, so that the server can subsequently adjust the first countdown information of the signal lamp based on the timestamp and the current time information, so as to ensure that the second countdown information obtained after adjustment by the server can match the countdown information actually displayed by the signal lamp at the target intersection.

[0060] Optionally, the data processing on the original signal lamp data to obtain the first signal lamp data comprises:

[0061] obtaining phase information of the original signal lamp data;

[0062] processing the phase information of the original signal lamp data according to the target phase representation mode to obtain the first signal lamp data with the target phase representation mode.

[0063] In the embodiments of the present disclosure, after the server obtains the original signal lamp data of the target intersection, the phase information of the original signal lamp data is obtained. It can be understood that different intersections or different signal lamps can have different representations of the phase information of the signal lamp. For example, in the signal lamp data corresponding to intersection A, 0 represents east-to-west straight, and 1 represents west-to-east straight, and in the signal lamp data corresponding to intersection B, 3 represents east-to-west straight, and 4 represents west-to-east straight. The same phase is represented by different information for the two intersections, which is not conducive to the processing of the server on the signal lamp data.

[0064] In the embodiments of the present disclosure, the server can be pre-configured with a target phase representation mode. After obtaining the original signal lamp data, the phase information of the original signal lamp data is processed based on the target phase representation mode, and the first signal lamp data with the target phase representation mode is obtained. That is, the server processes the phase information of the obtained original signal lamp data into the target phase representation mode with a unified data format. For example, the target phase representation mode can be: 0 represents east-to-west, 1 represents west-to-east, 2 represents south-to-north, 3 represents north-to-south, 4 represents east-to-west left turn, 5 represents west-to-east left turn, 6 represents south-to-north left turn, and 7 represents north-to-south left turn, etc. It can be understood that the server can obtain a large amount of original signal lamp data of intersections. By processing the phase information of the original signal lamp data into the target phase representation mode, the server can effectively identify the signal lamp data of different intersections or different signal lamps, and the processing of the first signal lamp data by the server is also facilitated.

[0065] It should be noted that the server can obtain signal lamp data of multiple intersections, for example, there are usually thousands of intersections, and the amount of data is large. The server can group the obtained signal lamp data, or dynamically group the intersections, for example, the off-line or fault intersection signal lamps can be removed in real time, which can effectively reduce the amount of data acquisition and subsequent processing, and then the signal lamp data of every 20 intersections is taken as a group, and a group of signal lamp data is pulled at a time, to ensure that the server can obtain the signal lamp data of multiple intersections in batches. In addition, in order to ensure real-time performance, the signal lamp data is acquired by 2Hz timing polling per second for each intersection. The server can use thread pool asynchronous processing of the signal lamp data to avoid network thread congestion.

[0066] In the embodiments of the present disclosure, the original signal lamp data obtained by the server can have different data formats based on different signal lamp manufacturers or different signal lamp models. The server can process the original signal lamp data with different data formats into the first signal lamp data with the same data format.

[0067] Optionally, the data processing on the original signal lamp data according to the data format of the original signal lamp data comprises:

[0068] In the case that the data format of the original signal lamp data comprises at least one phase of signal lamp color, the light-on duration of each signal lamp color corresponding to each phase in the original signal lamp data is counted;

[0069] According to the light-on duration, the first light-on period of each signal lamp color corresponding to each phase is determined;

[0070] According to the first light-on period of each signal lamp color, the first countdown information corresponding to each signal lamp color of each phase is obtained to obtain the first signal lamp data.

[0071] In some scenarios, the data format of the signal lamp is in the form of phase + color. For example, the data format of the original signal lamp data obtained by the server is: east-west straight + red light, that is, the color of the signal lamp corresponding to the east-west straight phase of the target intersection is red. It can be understood that the original signal lamp data obtained by the server for the target intersection can include the signal lamp color corresponding to each phase of the target intersection.

[0072] In the embodiments of the present disclosure, the server can obtain the signal lamp data of the target intersection in real time, for example, the server can obtain the signal lamp data of the target intersection at a timing of 2 Hz per second, and then the server can obtain the real-time color of each signal lamp of each phase for the same intersection. Further, the server can count the light-on duration of different signal lamp colors of each phase of the target intersection based on the obtained signal lamp data of the target intersection, for example, the light-on duration of the red light in the east-west straight phase, the light-on duration of the green light, etc. According to the counted light-on duration of each signal lamp color, the light-on period (i.e., the first light-on period) of each signal lamp color of each phase can be calculated, for example, the first light-on period of the green light is 30 seconds, the light-on period of the red light is 24 seconds, etc., so that the light-on period of the phase can be obtained. Further, according to the first light-on period of each signal lamp color of each phase, the first countdown information corresponding to different signal lamp colors of each phase can be calculated, so that the first signal lamp data including the signal lamp color of each phase of the target intersection and the first countdown information corresponding to each signal lamp color of each phase can be obtained.

[0073] In the embodiments of the present disclosure, when the data format of the original signal lamp data of the target intersection obtained by the server only includes phases, the server can count the lighting duration of each signal lamp color corresponding to each phase in the original signal lamp data of the target intersection continuously obtained within a certain duration, calculate the first lighting period of each signal lamp color corresponding to each phase according to the lighting duration, and determine the first countdown information of each signal lamp color corresponding to each phase at each moment, so as to convert the original signal lamp data into the first signal lamp data including the color and the first countdown information, thereby facilitating the adjustment of the server to the first countdown information. In this way, the signal lamp data (second signal lamp data) issued by the server to the terminal also includes the signal lamp colors of different phases and the corresponding countdown information (second countdown information), so that the terminal can intuitively obtain the current signal lamp color and the corresponding countdown information of each phase of the target intersection, thereby providing more direct and effective reference for the user's passing.

[0074] Optionally, the data processing on the original signal lamp data to obtain the first signal lamp data according to the data format of the original signal lamp data comprises:

[0075] When the data format of the original signal lamp data includes the color stage of the signal lamp, the phase number and the stage number of each signal lamp color included in the color stage are obtained.

[0076] Two continuous color stages are determined according to the stage number, and the second lighting period of each signal lamp color is determined according to the switching time interval of each signal lamp color corresponding to the two continuous color stages.

[0077] The first countdown information corresponding to the signal lamp color of each phase is obtained according to the second lighting period of each signal lamp color, so as to obtain the first signal lamp data.

[0078] In some scenarios, the data format of the signal lamp is the color stage. For example, the data format of the original signal lamp data obtained by the server is: the current running stage scheme (including several color stages) of each signal machine and the current running color stage number (including the phase number of the current green light), for example, the current running stage scheme includes three color stages, the current running color stage is red light, and the phase corresponding to the color stage is east-west straight.

[0079] In the embodiments of the present disclosure, the server can calculate the brightness period (i.e., the second light-on period) of each signal light color based on the switching time interval of each signal light color corresponding to each of the two continuous light color stages acquired continuously within a certain time length. For example, the server can determine the time interval of stage switching according to the two continuous light color stages, and then determine the second light-on period of the green light in a certain phase according to the switching time interval between the green lights (including the phase number corresponding to the green light) included in the two continuous light color stages. In this way, the second light-on period of each signal light color in different phases can be obtained. Further, the first countdown information corresponding to each signal light color in each time in each phase can be determined according to the second light-on period of each signal light color, so that the original signal light data is converted into the first signal light data including the light color and the first countdown information. In this way, the signal light data (second signal light data) sent by the server to the terminal also includes the signal light color in different phases and the corresponding countdown information (second countdown information), thereby providing more direct and effective reference for the user's passage.

[0080] In the embodiments of the present disclosure, the server can process the original signal light data in different data formats into the first signal light data including the light color and the first countdown information, so that the server is more flexible in processing the signal light data, and can also ensure that the signal light data sent by the server to the terminal also includes the signal light color in different phases and the corresponding countdown information, so that the terminal can intuitively obtain the current signal light color and the corresponding countdown information in each phase of the target intersection.

[0081] Optionally, before the adjusting the first countdown information based on the time delay compensation information to obtain the second signal light data of the target intersection, the method further includes:

[0082] obtaining a preset light-on time corresponding to the target signal light color of the target phase;

[0083] obtaining the first signal light color corresponding to the target signal light color of the target phase in the first signal light data;

[0084] adjusting the first countdown information corresponding to the first signal light color based on the preset light-on time in a case that the first countdown information corresponding to the first signal light color does not match the preset light-on time;

[0085] wherein, the target phase is any phase included in the first signal light data, the target signal light color is any one of the signal light colors included in the target phase, and the first signal light color is the same as the target signal light color.

[0086] It should be noted that, for an intersection, the green light duration and the red light duration of the opposite direction and the crossing direction (for example, the east-to-south left turn and the west-to-north left turn are a crossing direction) are generally the same, for example, the green light duration and the red light duration of the east-to-west straight line are the same as the green light duration and the red light duration of the west-to-east straight line, and the green light duration and the red light duration of the east-to-south left turn are the same as the green light duration and the red light duration of the west-to-north left turn. Therefore, the countdown information of the same signal light color of the opposite direction and the crossing direction of a certain intersection should also be the same. It can be understood that after the server obtains the countdown information of each signal light color of each phase of the target intersection, the countdown information may jump, and the countdown information may not be accurate.

[0087] In the embodiments of the present disclosure, after the server obtains the first signal light data of the target intersection, that is, the first countdown information of each signal light color under each phase of the target intersection can be obtained. Optionally, the server can determine the preset countdown information corresponding to the target signal light color of the target phase based on the countdown information of each signal light color under the same phase of the target intersection. For example, the green light duration corresponding to the south-to-north straight line is 59s, the green light duration corresponding to the north-to-south straight line is 60s, the green light duration corresponding to the east-to-west is 60s, and the green light duration corresponding to the west-to-east is 60s. Therefore, it can be obtained that the duration corresponding to the green light under the straight line phase should be 60s. In this case, it can be concluded that the green light duration corresponding to the south-to-north straight line is not accurate, which will cause the first countdown information of the green light of the phase to be inaccurate, that is, the first countdown information of the green light of the phase does not match the preset light-on duration.

[0088] Further, the server can adjust the first countdown information of the green light of the phase based on the preset light-on duration, for example, 1 second can be added to the first countdown information, so that the first countdown information of the green light of the phase is the same as or synchronized with the countdown information of the green light of other phases.

[0089] In the embodiments of the present disclosure, the server can adjust the first countdown information of different signal light colors under different phases, so as to ensure that the first countdown information corresponding to the same signal light color under different phases is the same, avoid the jump of the countdown information, and thus ensure the accuracy of the countdown information.

[0090] Optionally, in the embodiments of the present disclosure, the adjusting the first countdown information based on the time delay compensation information to obtain the second signal light data of the target intersection comprises:

[0091] determining a time delay compensation value according to the time delay compensation information;

[0092] acquire a first countdown value corresponding to the first countdown information;

[0093] determine second countdown information according to a difference between the first countdown value and the time delay compensation value, and obtain second signal lamp data including the second countdown information.

[0094] It can be understood that the first signal lamp data can have a transmission time delay, and the server can determine time delay compensation information based on current time information and a timestamp of the first signal lamp data, and determine a time delay compensation value according to the time delay compensation information. For example, the time delay compensation information includes the time delay compensation value. For example, the server acquires current time information of the first signal lamp data as 8:10:35, and the timestamp carried by the first signal lamp data is 8:10:33, and there is a time delay of 2s between them, and the time delay compensation value is 2.

[0095] Further, a first countdown value corresponding to the first countdown information is acquired, for example, the first countdown information is 30s, and the first countdown value is 30. It can be understood that, since the first signal lamp data has a transmission time delay of 2s, 2s is subtracted from the first countdown information to obtain the second countdown information, so that the adjusted second countdown information takes into account the transmission time delay of the signal lamp data, effectively ensuring the accuracy of the second signal lamp data. In this way, the second countdown information sent to the terminal can be synchronized with the actual countdown information of the target intersection signal lamp, effectively ensuring the accuracy of the signal lamp data in the terminal.

[0096] The embodiments of the present disclosure also provide a signal lamp data processing method, which is applied to a network architecture, such as Figure 2 As shown in the figure, the network architecture includes a traffic police special network, a (network or gateway) boundary and a shared platform, and the network architecture can send the processed signal lamp data to a terminal application.

[0097] Please refer to Figure 2 The traffic police special network includes a front-end machine (or processing platform), which acquires signal lamp data from a manufacturer background of a signal machine (i.e. signal lamp). The signal machine carries original signal lamp data, and the data formats of different signal machine manufacturers can be different. The signal machine can set different light color stages for different intersection types (cross intersection, T-shaped intersection, Y-shaped intersection, ring-shaped intersection, etc.), such as eight-phase four-stage, five-phase three-stage, etc. The light color stages of the intersection are not fixed, and the light color stages of different intersections at different time periods can also be not fixed.

[0098] The signal machine manufacturer background can monitor the signal machine, receive the original signal lamp data transmitted by the signal machine, and transmit the original signal lamp data to the front-end machine. The original signal lamp data can include intersection name, geographic position coordinates, signal machine identity (ID), signal machine light color stage, light color corresponding to each light color stage, phase, countdown information, etc.

[0099] The front-end machine can perform data pulling and preprocessing on the received original signal lamp data. Because the original signal lamp data of N intersections is generally thousands of pieces, it is impossible to pull them through one interface, and the data volume will be very large. The intersections can be dynamically grouped (real-time exclusion of offline intersections), and generally 20 intersection data can be pulled at a time. According to the grouping of intersections, N / 20. In order to ensure real-time performance, each intersection will be polled at a rate of 2Hz per second to obtain data. In order to avoid network thread congestion, thread pool asynchronous processing can be used. Further, the received original signal lamp data is adapted and analyzed, and the phase information expressed by different types of signal machines is converted into internal standard format phase information, for example, the standard format is: 0 represents east to west, 1 represents west to east, 2 represents south to north, 3 represents north to south, 4 represents east to west left turn, 5 represents west to east left turn, 6 represents south to north left turn, and 7 represents north to south left turn.

[0100] Further, different signal machine manufacturers can have different data formats, and the front-end machine needs to process the original signal lamp data in different data formats into signal lamp data with the same data format. There are generally the following processing schemes:

[0101] Scheme one: the data format of the original signal lamp data includes at least one phase signal lamp color, the front-end machine counts the real-time light color of each phase of each signal machine obtained from the signal machine manufacturer background, and when the light color switches, the red, yellow and green light color time of each phase can be counted, and the cycle of a certain phase and the green light switching time are calculated, so that the light color + countdown of each phase at each time can be calculated according to the switching time.

[0102] Scheme two: the data format of the original signal lamp data is the light color stage, the front-end machine obtains the current running stage scheme (including several stages) and the current running stage number (including the phase number of the current green light) of each signal machine from the signal machine manufacturer platform, and based on the phase number contained in the continuous stage when the stage switches, the green light switching time (i.e. the green light time) of the phase can be calculated. The interval between two switching times is the cycle of the phase, and the yellow and red light time can be calculated according to the cycle, and then the light color + countdown of each phase at each time can be derived.

[0103] Scheme three: the signal lamp data obtained by the front-end machine from the vendor background is the lamp color + countdown of each phase of each signal machine, and in this case, no processing is needed.

[0104] Further, for the processed signal lamp data, a time compensation timestamp is generated according to the original signal lamp data. Generally, the green light and red light time of the opposite direction is generally the same, so it is necessary to do phase stabilization operation on the opposite phase of the opposite direction, such as the green light time of south to north is 59s, the green light time of north to south is 60s, the green light time of east to west is 60s, and the green light time of west to east is 60s, then the green light time of south to north is calibrated to 60s. Similarly, the same phase and same color time of the previous period can be self-learning calibrated, so as to achieve a stable state and prevent the countdown from frequently jumping. Therefore, the accuracy of the signal lamp data can be ensured.

[0105] The above signal lamp data (lamp color + countdown) processed by the front-end machine can be transmitted from the traffic police special network to the service sharing platform through the network gate boundary. The platform mainly performs data synchronization. The service sharing platform includes a data sharing platform and a network service platform. After the data sharing platform obtains the signal lamp data, it is stored in the intranet database. The network gate actively scans the change items on the source database in the intranet area and synchronizes them to the database of the data sharing platform.

[0106] The network service platform supports the following three ways to obtain the signal lamp data synchronized to the data sharing platform: subscription, http push, and query. Taking the query mode as an example, the lamp color + countdown data obtained at this time has experienced the time delay when the data is out of the network gate boundary, so it is necessary to perform a delay compensation operation according to the timestamp generated by the above original data, and provide the lamp color + countdown data after delay compensation to the terminal.

[0107] The terminal includes but is not limited to self-built terminal such as recorder and operating vehicle, navigation application, cloud platform of vehicle enterprise, and vehicle. Further, the terminal outputs the received lamp color + countdown data, for example, displays it on the navigation application, so as to better provide direct and effective reference for the user's travel.
