Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the signal light countdown method or apparatus of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The user may use the terminal devices 101, 102, 103 to interact with the server 105 via the network 104 to receive or send messages or the like. Various communication client applications, such as a driving assistance application, a navigation application, a video application, a live application, an instant messaging tool, a mailbox client, social platform software, and the like, may be installed on the terminal devices 101, 102, and 103.
Here, the terminal apparatuses 101, 102, and 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices having a display screen, including but not limited to smart phones, tablet computers, e-book readers, laptop portable computers, desktop computers, and the like. When the terminal apparatuses 101, 102, 103 are software, they can be installed in the electronic apparatuses listed above. It may be implemented as multiple pieces of software or software modules (e.g., multiple pieces of software or software modules to provide distributed services) or as a single piece of software or software module. And is not particularly limited herein.

The background server may analyze and perform other processing on the received data such as the countdown data request, and feed back a processing result (e.g., countdown data) to the terminal device.
It should be noted that the method for signal lamp countdown provided in the embodiment of the present application may be executed by the terminal devices 101, 102, and 103, and accordingly, the apparatus for signal lamp countdown may be disposed in the terminal devices 101, 102, and 103.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method of signal lamp countdown according to the present application is shown. The signal lamp countdown method is used for a terminal and comprises the following steps:
In this embodiment, an execution subject (for example, the terminal device shown in fig. 1) on which the signal lamp countdown method operates may acquire countdown data of a signal lamp of a nearest intersection from the cloud server when entering a fence range of the nearest intersection in a traveling direction. Specifically, the nearest intersection in the traveling direction refers to an intersection through which the terminal immediately passes. The countdown data are real-time data of the signal lamp. That is, the signal lights of the nearest intersection are counting down with the count-down data. For example, the countdown may be second reading data in seconds, or may be accurate to other accuracy such as milliseconds. The travel direction here guides the direction indicated in the navigation information for the route planned for the terminal.
In practice, the fence range may be a circular range with the center of the intersection as the center, and therefore, the radius of the circular range is the fence radius. The executing body may determine that the terminal enters the fence range in a case that a distance from the terminal to a center of the nearest intersection is less than or equal to the fence radius.
The signal light is a light provided at the intersection to indicate that the vehicle stops or passes, and may be a traffic light, for example.
In this embodiment, if the execution main body determines that the countdown data is the countdown data acquired for the first time for the nearest intersection, the execution main body locally starts the countdown corresponding to the countdown data, and generates and displays local countdown information. That is, the countdown data acquired for the first time herein refers to countdown data acquired for the first time by the execution main body when or after entering the fence range for the present time. In practice, the execution subject locally starts the countdown, and may obtain the related information of the local countdown, that is, the local countdown information.
The execution main body may determine whether the countdown data is first acquired for the nearest intersection when entering the fence range, and locally start countdown when the countdown data is determined to be yes.
And step 203, responding to the zero resetting of the local countdown information, and stopping displaying the local countdown information.
In this embodiment, the execution subject may stop the local countdown information when the local countdown information is reset to zero. In practice, the countdown stop condition may be various, and for example, the execution subject may determine that the countdown stop condition is satisfied after 5 seconds from the time when the local countdown information is zero.
Alternatively, in a case where it is determined that the terminal has passed through the nearest intersection (for example, passed through an intersection center), the executing body may determine that a countdown stop condition is satisfied, and stop presenting the local countdown information.
The method provided by the embodiment of the application can perform local signal lamp countdown under the condition that the distance from the intersection is close, so that the problem that accurate countdown cannot be displayed under the conditions of network disconnection and the like is solved, and the signal lamp countdown is guaranteed to be displayed locally and smoothly.
In some optional implementations of this embodiment, the stopping presenting the local countdown information in response to the local countdown information returning to zero in step 204 may include: and if the displayed local countdown information is the local countdown information of the signal lamp in the advancing direction of the terminal, responding to the local countdown information zero resetting, and stopping displaying the local countdown information.
In these alternative implementations, the execution main body may stop presenting the local countdown information in response to the presented local countdown information being the local countdown information of the signal light in the traveling direction of the terminal. Specifically, the traveling direction of the terminal may be determined by navigation information for the terminal. The traveling direction of the terminal is a single traveling direction, and the signal light of the traveling direction of the terminal may be one of four signal lights of left turn, right turn, turn around, and straight traveling.
The implementation manners can directly close the local countdown information under the condition that the countdown information displayed aiming at the advancing direction of the terminal returns to zero, so that useless display of the countdown information is avoided.
In some optional implementations of this embodiment, the stopping presenting the local countdown information in response to the local countdown information returning to zero in step 204 may include: and if the displayed local countdown information is the local countdown information of the signal lamps in the at least two advancing directions, responding to the fact that the countdown information of the signal lamps in the at least two advancing directions are all reset to zero, and stopping displaying the local countdown information.
In these alternative implementations, the local countdown information presented by the terminal may be local countdown information for signal lights in multiple directions of travel. That is, the local countdown information of the signal lights of the plurality of traveling directions includes the local countdown information of the signal light of the traveling direction of the terminal, such as the local countdown information of the signal light of the left turn direction at the nearest intersection, where the left turn direction is the direction indicated by the navigation information to the terminal. In addition, the local countdown information for the plurality of heading signals may also include local countdown information for other heading signals, such as turn right, go straight, and turn around signals at the nearest intersection.
In practice, the countdown information of the signal lamps in all traveling directions is sequentially and completely zeroed, often because the connection between the current terminal and the cloud server is already disconnected.
In these implementations, if the connection between the terminal and the server is disconnected, the terminal may stop displaying the local countdown when the countdown for each traveling direction is zero, thereby ensuring the accuracy of the local countdown.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for signal lamp countdown according to the present embodiment. In the application scenario of fig. 3, in response to the terminal entering a fence range of a nearest intersection in the traveling direction, the execution main body 301 acquires countdown data 302 of a signal lamp of the nearest intersection from the cloud server, where the countdown data is real-time data. The execution main body 301 responds to the countdown data 302 which is acquired for the first time at the nearest intersection under the condition of entering the fence range, locally starts countdown corresponding to the countdown data acquired for the first time, and generates and displays local countdown information 303. The execution principal 301 stops presenting the local countdown information 304 in response to the local countdown information zeroing.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method of signal light countdown is shown. The process 400 includes the following steps:
In this embodiment, an execution body (for example, the terminal device shown in fig. 1) on which the method for signal lamp countdown operates may acquire countdown data of a signal lamp of a nearest intersection from a cloud server in a case where the terminal has established a long connection with the cloud server and the terminal enters a fence range of the nearest intersection in a traveling direction.
In this embodiment, the executing body may locally start countdown corresponding to the countdown data when the countdown data is the countdown data acquired for the first time at the nearest intersection when the terminal enters the fence range at this time. That is, the countdown data acquired for the first time herein refers to countdown data acquired for the first time by the execution main body when or after entering the fence range for the present time. In practice, the countdown is started locally, and the information related to the local countdown is obtained as the local countdown information.
And step 403, in response to the countdown stopping condition being met, stopping displaying the local countdown information.
In this embodiment, the executing body may stop the local countdown information when the terminal meets a countdown stop condition.
The embodiment can realize that the countdown data is acquired from the cloud server by establishing the long connection.
In some optional implementations of this embodiment, the method may further include: and in response to that the countdown data are acquired for the nearest intersection for a non-first time under the condition of entering the fence range and are inconsistent with the current local countdown information, calibrating the local countdown information by using the countdown data.
In these alternative implementations, the non-first-acquired countdown data here refers to non-first-acquired countdown data of the execution subject when or after entering the fence range, such as second-acquired or third-acquired countdown data.
In practice, the execution body may acquire countdown data periodically, such as once per second. In addition, the execution main body may calibrate the local countdown information by using the acquired countdown data when the countdown data is inconsistent with the local countdown information. Specifically, the execution main body may determine whether the acquired countdown data is consistent with the local countdown information, so as to determine that the countdown data is inconsistent with the local countdown information.
The optional implementation manners can utilize the countdown data which is not acquired for the first time to calibrate the local countdown information, and the accuracy of local countdown can be further improved.
With further reference to fig. 5, as an implementation of the method shown in the above figures, the present application provides an embodiment of a signal lamp countdown apparatus, which corresponds to the method embodiment shown in fig. 2, and which may include the same or corresponding features or effects as the method embodiment shown in fig. 2, in addition to the features described below.
