It should be understood that the content described in this section is not intended to identify the key or important features of the embodiments of the present application, nor is it used to limit the scope of the present application. Other features of the present application would become readily comprehensible from the following description.
The drawings are used to better understand the present solution, but do not constitute a limitation on the present application. Among them:
The exemplary embodiments of the present application are described below with reference to the drawings, and various details of the embodiments of the present application are included therein to facilitate understanding, and should be regarded as merely exemplary. Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.
An annunciator refers to a controller for a signal light at an intersection. Generally speaking, annunciators of different manufacturers have different signal control representation strategies, and annunciators of the same manufacturer have different light state representation strategies for the annunciators.
The signal control representation strategy may be understood as a representation method of a strategy for controlling a signal light. For example, according to industry standards for signal light manufacturing, signal lights may be divided into ring diagram type annunciators and stage type annunciators, where the ring diagram type annunciators have a signal control representation strategy different from that of the stage type annunciators.
The light state representation strategy may be understood as a representation method of a strategy for representing light states of the signal lights, where the light states of the signal lights may be color information of the signal lights, such as green light ON and green light duration. Some annunciators have such a light state representation strategy: R represents red lights; and some annunciators have such a light state representation strategy: 1 represents red lights.
A plurality of sections are included in a city, and an individual section may be provided with a plurality of annunciators; based on the above analysis, it can be seen that different annunciators may have different signal control representation strategies, or may have different light state representation strategies.
However, with the development of intelligent transportation technology, how to avoid traffic congestion and improve traffic efficiency of vehicles and/or pedestrians has become an urgent problem to be solved.
In related technologies, considering that different annunciators may have different signal control representation strategies or different light state representation strategies, in order to achieve unified control and management to avoid traffic congestion, a commonly-used method lies in: dividing a city into a plurality of region, deploying annunciators of the same manufacturer (that is, annunciators with the same signal control representation strategy) per region, and adjusting signal control information (such as light state information, etc.) of an individual annunciator by receiving the signal control information sent by the respective annunciator within the region and in combination with physically positional relationship of the respective annunciator in the region.
However, the above-mentioned method in the prior art has relatively strict requirements on annunciator deployment and lacks flexibility. On the other hand, annunciators of the same manufacturer may have different light state representation strategies, and annunciators with different state representation strategies cannot work collaboratively, leading to technical problems such as traffic congestion and low traffic efficiency.
In order to solve at least one of the above-mentioned technical problems, the inventors of the present application obtains the inventive concept of the present application through creative work: on the basis of a preset reference representation strategy, the acquired original attribute information of an individual annunciator is parsed to obtain parsed attribute information, so that respective annunciators have the same representation strategy (that is, the signal control representation strategy and/or the light state representation strategy), and adjustment information is generated based on the parsed attribute information.
The present application provides an annunciator control method, an electronic device and a system, which are applied to the field of intelligent transportation and cloud computing in artificial intelligence technology to achieve the flexibility and diversity of the annunciator deployment and improve traffic efficiency.
S101: acquiring original attribute information of an individual annunciator.
The respective original attribute information includes: original attribute information of an annunciator with a different light state representation strategy and/or original attribute information of an annunciator with a different signal control representation strategy.
Exemplarily, an execution subject of this embodiment may be the first electronic device. The first electronic device may specifically be a server (for example, a cloud server or a local server), or a terminal device, or a processor, or a chip etc., which is not limited in this embodiment.
It should be understood that “original” in the original attribute information is used to distinguish from the parsed attribute information hereinafter, and cannot be understood as a limitation to the original attribute information.
The original attribute information may be understood as an annunciator's light state attribute related information represented by the light state representation strategy; the original attribute information may also be understood as an annunciator's control attribute related information represented by the signal control representation strategy; and the original attribute information may also be understood as including the aforementioned two kinds of attribute related information.
It is worth noting that the annunciator control method of this embodiment may render control on a plurality of annunciators, and the plurality of annunciators may be annunciators with different signal control representation strategies, or may be annunciators with different light state representation strategies, or may be annunciators with both different signal control representation strategies and different light state representation strategies.
That is, on the one hand, according to the annunciator control method provided in this embodiment, there is no need to adopt respective control methods for annunciators with different signal control representation strategies and/or annunciators with different light state representation strategies, so that a unified control is achieved between the annunciators with different signal control representation strategies and/or the annunciators with different light state representation strategies, and a convenient and universal control is achieved over the annunciators with different signal control representation strategies and/or the annunciators with different light state representation strategies, thereby reducing the research and development resources and improving resource utilization; on the other hand, the annunciator control method of this embodiment does not have harsh and mandatory requirements on annunciator deployment, and has flexibility and versatility in application.
S102: parsing the respective original attribute information according to a preset reference representation strategy to obtain respective parsed attribute information corresponding to the respective original attribute information.
The individual piece of parsed attribute information is attribute information represented by the preset reference representation strategy, the respective parsed attribute information is used to generate adjustment information, and the adjustment information is used to adjust signal control information of at least one annunciator.
The signal control information may be understood as information related to the time and state of a signal light, for example, a period of the signal light, a green time ratio of the signal light, a phase difference (that is, a relative time difference between cycle beginnings of intersections) of the signal light and phase conversion information, etc.
In an example, if the original attribute information includes original attribute information of annunciators with different signal control representation strategies, the preset reference representation strategy may be understood as a strategy which is a conversion standard of the signal control representation strategy, that is, different signal control representation strategies all may be represented by the preset reference representation strategy, thereby realizing a unified representation between different signal control representation strategies.
For example, for original attribute information a represented by a signal control representation strategy A, the first electronic device may convert the original attribute information a to parsed attribute information of a preset reference representation strategy C; and for original attribute information b represented by a signal control representation strategy B, the first electronic device may convert the original attribute information b into the parsed attribute information of the preset reference representation strategy C.
In another example, if the original attribute information includes original attribute information of annunciators with different light state representation strategies, the preset reference representation strategy may be understood as a strategy which is a conversion standard of the light state representation strategy, that is, different light state representation strategies all may be represented by the preset reference representation strategy, thereby realizing a unified representation between different light state representation strategies.
For example, for original attribute information d represented by a light state representation strategy D, the first electronic device may convert the original attribute information d to parsed attribute information of a preset reference representation strategy F; and for original attribute information e represented by a light state representation strategy E, the first electronic device may convert the original attribute information e into the parsed attribute information of the preset reference representation strategy F.
In yet another example, if the original attribute information includes original attribute information of annunciators with different signal control representation strategies and original attribute information of annunciators with different light state representation strategies, the preset reference representation strategy may include a strategy which is a conversion standard of the signal control representation strategy and a strategy which is a conversion standard of the light state representation strategy, reference may be made to the aforementioned two examples for specific conversion principles, and redundant description is omitted here.
Based on the above analysis, an embodiment of the present disclosure provides an annunciator control method, the method is applied to a first electronic device, and the method includes: acquiring original attribute information of an individual annunciator, where the respective original attribute information includes original attribute information of an annunciator with a different light state representation strategy and/or original attribute information of an annunciator with a different signal control representation strategy; and parsing the respective original attribute information according to a preset reference representation strategy to obtain respective parsed attribute information corresponding to the respective original attribute information, where an individual piece of parsed attribute information is attribute information represented by the preset reference representation strategy, the respective parsed attribute information is used to generate adjustment information, and the adjustment information is used to adjust signal control information of at least one annunciator. In this embodiment, the feature of parsing the respective original attribute information based on the preset reference representation strategy to obtain the attribute information represented by the preset reference representation strategy (that is, the parsed attribute information) is introduced, which may realize a unified representation of original attribute information of annunciators with different light state representation strategies and/or a unified representation of original attribute information of annunciators with different signal control representation strategies, thereby avoiding disadvantages that the annunciator control method has strict requirements on annunciator deployment in the related art, and realizing the application flexibility of the annunciator control method, moreover, a technical effect that signal control information adjustment may be improved in flexibility, accuracy and reliability by means of generating adjustment information based on the respective parsed attribute information to adjust signal control information of one or more annunciators based on the adjustment information.
S201: acquiring original attribute information of an individual annunciator.

Exemplarily, for descriptions on the annunciator, the original attribute information and the light state representation strategy, reference may be made to the first embodiment, and the redundant description is omitted herein.
Similarly, “original” in the original light state information is used to distinguish from the parsed light state information hereinafter, and cannot be understood as a limitation to the original light state information. In combination with the above embodiments, the original light state information may be understood as light state attribute related information.
S202: determining a deployment region.
The respective annunciator is included in the deployment region, that is, the deployment region is a region for deploying the respective annunciator.

The individual piece of parsed light state information is attribute information represented by the light state reference representation strategy, the respective parsed attribute information is used to generate adjustment information, and the adjustment information is used to adjust signal control information of at least one annunciator.
In this embodiment, the original attribute information includes original light state information and, correspondingly, the preset reference representation strategy includes the light state reference representation strategy.
In particular, the first electronic device parses the original light state information represented based on the light state representation strategy according to the light state reference representation strategy to obtain the parsed light state information represented by the light state reference representation strategy.
It is worth to be noted that, in this embodiment, by parsing the respective original light state information in the deployment region based on the light state reference representation strategy to obtain the respective parsed light state information, the signal light control method in this embodiment may be applied to a region including signal lights with different light state representation strategies, which improves the application flexibility of the signal light control method, moreover, by generating the adjustment information based on the respective parsed light state information, the adjustment information may be highly correlated with the annunciators, so that the technical effect of improving the reliability and the efficiency of the adjustment information may be achieved, and the technical effect of improving the control accuracy and reliability when adjusting the signal control information based on the adjustment information may be achieved.

This embodiment may be understood as: the deployment region has annunciator road network information, and the annunciator road network information includes deployment location information of the annunciator in the deployment region, that is, the deployment location information of the respective annunciator in the deployment region may be determined by the annunciator road network information. Correspondingly, the first electronic device may convert the light state representation strategy of the individual piece of original light state information to the parsed light state information represented by the light state reference representation strategy, in combination with the light state reference representation strategy and the deployment location information of the respective annunciator.
It is worth to be noted that, in this embodiment, by determining the respective parsed light state information in combination with the light state reference representation strategy and the annunciator road network information, the parsed light state information may be highly compatible with the deployment location information, and the accuracy and reliability of the parsed light state information may be improved.

In some embodiments, the parsed light state information may include: intersection identification, meta-information (for example, an original timestamp of a signal light), state information (for example, the online state or the offline state), a control mode (for example, different light state solutions of a signal light in different time periods, which may specifically include solution identification, solution cycle, solution countdown, etc.), a phase state (that is, information on different directions at an intersection, such as phase identification, light color, light color countdown, etc.).
It is worth to be noted that, in this embodiment, by generating the parsed light state information in combination with the two dimensions of content, completeness, comprehensiveness and diversity of the parsed light state information may be improved, so that the technical effect of improving the accuracy and the reliability of the adjustment information generated based on the respective parsed light state information may be achieved.

The third step: constructing a binding relationship between the individual intersection and the annunciator(s) provided at the intersection.
Exemplarily, if one annunciator is provided at one intersection, the binding relationship may characterize a corresponding relationship between the intersection and the one annunciator; if more annunciators are provided at one intersection, the binding relationship may characterize a corresponding relationship between the intersection and the annunciators.
It is worth to be noted that, in this embodiment, by determining the annunciator(s) at the individual intersection and constructing the binding relationship between the individual intersection and the annunciator(s) provided at the intersection, the binding relationship may have a more comprehensive coverage, and thus the technical effect of having relatively high accuracy and reliability is achieved.
