[0029] Roadside intelligent stations play a crucial role in modern transportation systems. They collect data from various sensors and use this data to control different types of information dissemination devices. However, as the dimensionality of input data continues to increase, as does the number and type of information dissemination devices, it becomes increasingly difficult to implement fixed strategies for controlling these devices.

[0030] Specifically, in traditional technologies, each information publishing device uses a fixed strategy to implement information publishing. That is, each information publishing device outputs a fixed set of information based on the input sensor data. This information publishing device control method requires that each additional dimension of sensor or information publishing device requires the configuration of a fixed information publishing strategy. As the dimensions of input data continue to increase, as well as the types and number of information publishing devices continue to increase, the number of fixed strategies will increase exponentially, making the management of fixed strategies extremely complex. Road managers will find it difficult to flexibly and quickly add, delete, and modify fixed strategies. In addition, they will not be able to accurately perform personalized device management and information broadcasting based on real-time complex road conditions, diverse weather conditions, and various events to adapt to ever-changing traffic conditions. There are problems such as a surge in the number of strategies, difficulty in adjusting strategies, and insufficient personalized management.

[0031] Based on this, the embodiments of the present application provide a control method, apparatus, device and readable storage medium for an information release device, which matches the identified sensor event with the trigger condition of a pre-stored plan through a roadside intelligent station, and when the sensor event successfully matches the trigger condition of the first target plan, the target information release device is determined according to the control content of the first target plan, and the device control instructions corresponding to the target information release device are generated, thereby realizing flexible control of information release of the target information release device, without the need to set a fixed control strategy for each information release device. Therefore, the problem of excessive increase in the number of control strategies will not occur, and the difficulty of control of the information release device is reduced.

[0032] In order to facilitate understanding by those skilled in the art, the solutions of the present application are described below by way of examples.

[0033] For example, Figure 1 As shown, it is a structural schematic diagram of the control system of the information release device provided in an embodiment of the present application. The control system includes a vehicle-road cloud platform 11, a roadside smart station 12 communicatively connected to the vehicle-road cloud platform 11, a sensor 13 communicatively connected to the roadside smart station 12, and an information release device 14.

[0034] The vehicle-road cloud platform 11 can be implemented by a server capable of loading an intuitive and easy-to-use user interface. This user interface can include an operation area for road managers to configure emergency plans. Road managers can add, delete, and modify plans by clicking and dragging, while also providing a real-time preview function. After the road manager confirms and issues an emergency plan, if the plan is triggered by an event, the preview interface can display the control status of each information release device 14 in real time. For sensitive devices (such as information boards), the preview interface can also prompt the road manager to confirm the issuance of device control instructions through a pop-up window to ensure that the content released by sensitive devices has been manually reviewed. Road managers can also modify already issued device control instructions through the user interface. For example, they can modify the device release content of an already triggered emergency plan and send the modified content to the roadside intelligent station 12. After receiving the modified content, the roadside intelligent station 12 re-issues the modified content to the corresponding target information release device. After modifying the emergency plan, the road manager can immediately see the effect simulation through the user interface.

[0035] In one embodiment of the present application, the user interface of the vehicle-road cloud platform 11 can be loaded with a map, which displays different road sections, weather conditions, and the different statuses of different information dissemination devices in different colors and symbols. For example, sections with good road conditions are displayed in green, and sections with bad weather are displayed in yellow, with the corresponding weather type, such as rain, snow, and fog, being marked. The working status of information dissemination devices such as information boards and variable speed limit signs can also be displayed in real time on the user interface. For example, normally functioning devices are displayed in bright colors, and faulty devices are displayed in dark colors.

[0036] In the embodiment of the present application, the roadside intelligent station 12 in the control system is a software and hardware system deployed on the roadside that has functions such as information aggregation, information processing, decision generation and distribution. It can receive sensor data collected by the sensor 13 and identify the sensor data to obtain sensor events. Then, the sensor events are matched with the trigger conditions of the pre-stored plan. When the sensor event successfully matches the trigger conditions of the first target plan, the target information release device is determined based on the control content of the first target plan and a device control instruction corresponding to the target information release device is generated. Then, the device control instruction is sent to the target information release device to control the information release of the target information release device. This realizes flexible control of information release of the target information release device, avoids the problem of excessive increase in the number of control strategies, and reduces the difficulty of controlling the information release device.

[0037] It should be noted that the target information release device in the embodiment of the present application is one or more of the multiple information release devices 14 that are communicatively connected to the roadside intelligent station 12.

[0038] In the embodiment of the present application, the sensor 13 may include a temperature sensor, a humidity sensor, a road surface condition sensor (e.g., a road surface water film thickness sensor, a road surface ice thickness sensor, a road surface temperature sensor), a wind speed and direction sensor, a radar sensor, and an image sensor (e.g., a camera). The information release device 14 may include a message board, a variable speed limit sign, an induction light, a tweeter, and an on-board unit configured on a vehicle. The present application does not limit the types of the sensor 13 and the information release device 14.

[0039] like Figure 2 As shown, it is a schematic diagram of the implementation flow of the control method of the information release device provided in an embodiment of the present application. The control method of the information release device is applied to the roadside intelligent station in the above-mentioned control system, and can be executed by the control device of the information release device on the roadside intelligent station. The control device of the information release device can be implemented in hardware or software. The control method of the information release device can be implemented in the following steps 101 to 104.

[0040] Step 101: Receive sensor data collected by a sensor, identify the sensor data, and obtain sensor events.

[0041] In the embodiments of the present application, the roadside intelligent station can identify weather events, road condition events, and traffic events by identifying sensor data collected by sensors (e.g., temperature, humidity, road water film thickness, road ice thickness, road temperature, wind speed, wind direction, radar data, and image data). For example, weather events such as rain, snow, or typhoon weather; road condition events such as icy roads, flooding, or road construction; and traffic events such as traffic congestion, rear-end collisions, and vehicle breakdowns.

[0042] For example, by identifying the radar data collected by the radar sensor, we can obtain the size, speed and position of vehicles on the road, and then determine whether there is congestion on the road, as well as traffic events such as the estimated time of congestion. By identifying the radar data collected by the radar sensor and the road images collected by the image sensor, we can determine whether there are traffic events such as traffic congestion, vehicle rear-end collision, and vehicle failure on the road.

[0043] Step 102: Match the sensor event with the triggering condition of the pre-stored plan.

[0044] In this embodiment of the present application, a road manager can configure the contents of a plan through the user interface of the vehicle-road cloud platform and click "Submit Plan." The vehicle-road cloud platform then sends the plan to the roadside intelligent station. After receiving the plan, the roadside intelligent station can verify the legitimacy of the plan and, if the plan passes the verification, store it.

[0045] In the embodiment of the present application, the content of the plan includes the triggering conditions and control content of the plan.

[0046] The trigger conditions may include event types and trigger parameters. Event types may include traffic events, weather events, and road condition events. Trigger parameters may include time periods, road section ranges, weather parameters, traffic flow parameters, and event status (e.g., occurrence, duration, update, and end of the event).

[0047] The control content may include the broadcast list, broadcast method, broadcast frequency, broadcast number and broadcast content (published content) of the information release device.

[0048] In step 102, when matching the sensor event with the trigger conditions of the pre-stored plans, the sensor event can be matched with the pre-stored plans one by one. When the sensor event successfully matches the event type and trigger parameters of a pre-stored plan (i.e., the first target plan), it is confirmed that the sensor event successfully matches the trigger conditions of the first target plan.

[0049] Step 103: When the sensor event successfully matches the triggering condition of the first target plan, the target information release device is determined according to the control content of the first target plan, and a device control instruction corresponding to the target information release device is generated.

[0050] In this embodiment of the present application, the first target plan is one of the plans pre-stored by the roadside intelligent station. When a sensor event successfully matches the triggering conditions of the first target plan, the roadside intelligent station can select a target information release device based on the information release device broadcast list in the control content of the first target plan and generate a device control instruction corresponding to the target information release device.

[0051] For example, a device control instruction is generated for controlling the information board to display the content pre-set in the first target plan, or a device control instruction is generated for controlling the variable speed limit sign to display a certain speed limit value pre-set in the first target plan, or a device control instruction is generated for controlling the on-board unit (OBU) to broadcast the broadcast content pre-set in the first target plan (such as voice prompts, text displays, video and picture displays, etc.).

[0052] In the embodiment of the present application, the information release device broadcast list records the information release devices that need to release information.

[0053] Step 104: Send the device control instruction to the target information publishing device.

[0054] In an embodiment of the present application, the aforementioned device control instructions are used to control the information release of a target information release device. This application uses a roadside intelligent station to match the identified sensor events with the trigger conditions of a pre-stored plan. When the sensor event successfully matches the trigger conditions of the first target plan, the target information release device is determined based on the control content of the first target plan, and a device control instruction corresponding to the target information release device is generated. This allows the target information release device to release information based on the device control instruction after receiving the device control instruction sent by the roadside intelligent station, thereby achieving flexible control of information release for the target information release device.

[0055] The control method of the information release device of the present application does not require setting a fixed control strategy for each information release device. Instead, the information release device is controlled by matching the identified sensor events with the trigger conditions of the pre-stored plan. Therefore, the problem of excessive increase in the number of control strategies will not occur, and the difficulty of managing and controlling the information release device is reduced.

[0056] In addition, the control method for the above-mentioned information release equipment allows road managers to configure and issue emergency plans through the user interface of the vehicle-road cloud platform based on real-time changes in complex road conditions, diverse weather conditions, and various events. The roadside intelligent station controls the information release equipment to release information by matching the identified sensor events with the trigger conditions of the pre-stored emergency plans, achieving precise and personalized equipment control and information broadcasting to meet the increasingly complex traffic management needs. In addition, it also allows road managers to add, delete, and modify emergency plans in real time according to actual needs to adapt to changing traffic conditions. This solves the problems of traditional information release equipment control methods, such as the surge in the number of strategies, difficulty in adjusting strategies, and insufficient personalized control.

[0057] The control method of the information release device of the embodiment of the present application can enable road managers to conveniently and accurately control the information release of the information release device, reduce the difficulty of controlling the information release device, and alleviate the control burden of the information release device.

[0058] In one embodiment of the present application, Figure 3 As shown, in addition to the above steps 101 to 104, the control method of the information release device can also execute the following steps 201 to 204 to control the information release of the information release device based on external input events, thereby improving the control flexibility of the information release device.

[0059] Step 201: Receive an external input event sent by the vehicle-road cloud platform.

[0060] In the embodiments of the present application, the aforementioned external input events may include events input by a third-party platform received by the vehicle-road cloud platform, or manually configured events. For example, these may include traffic events, weather events, or road condition events released by the traffic management department's traffic management platform, or traffic events, weather events, or road condition events reported by third-party mapping software, or road events issued by road managers for temporary road control due to events or other reasons. This application does not limit the types of external input events.

[0061] Step 202: Match the external input event with the triggering conditions of the pre-stored plan.

[0062] In an embodiment of the present application, when matching an external input event with the trigger conditions of a pre-stored plan, the external input event can be matched with the pre-stored plans one by one. When the event type and trigger parameters of the external input event and a certain plan (i.e., the second target plan) in the pre-stored plans all match successfully, it is confirmed that the external input event successfully matches the trigger conditions of the second target plan.

[0063] Step 203: When the external input event successfully matches the triggering condition of the second target plan, the target information release device is determined according to the control content of the second target plan, and a device control instruction corresponding to the target information release device is generated.

[0064] In the embodiment of the present application, the second target plan is one of the plans pre-stored by the roadside intelligent station. The pre-stored plan by the roadside intelligent station can be a plan sent by the vehicle-road cloud platform, and can also be a plan configured and issued by the road manager through the user interface of the vehicle-road cloud platform.

[0065] Step 204: Send the device control instruction to the target information publishing device.

[0066] In an embodiment of the present application, the above-mentioned device control instruction is used to control the information release of the target information release device. After receiving the device control instruction sent by the roadside intelligent station, the target information release device can release information based on the device control instruction.

[0067] In one embodiment of the present application, in order to avoid the roadside intelligent station issuing the same device control instructions multiple times for the same event, before the above step 102 matches the sensor event with the trigger condition of the pre-stored plan, and before step 202 matches the external input event with the trigger condition of the pre-stored plan, the sensor event and the external input event can be pre-processed to obtain the target event, and then the target event is matched with the trigger condition of the pre-stored plan. When the target event successfully matches the trigger condition of the pre-stored plan, the target information release device is determined according to the management and control content of the plan, and the device control instruction corresponding to the target information release device is generated to control the information release of the target information release device.

[0068] For example, Figure 4 As shown, the control method of the information publishing device can be implemented by adopting the following steps 301 to 305.

[0069] Step 301: receiving sensor data collected by a sensor, identifying the sensor data, and obtaining sensor events; receiving external input events sent by the vehicle-road cloud platform;

[0070] Step 302: Preprocess the sensor events and external input events to obtain target events.

[0071] Step 303, matching the target event with the triggering conditions of the pre-stored plan;

[0072] Step 304: When the target event successfully matches the triggering condition of the pre-stored plan, the target information release device is determined according to the control content of the plan, and a device control instruction corresponding to the target information release device is generated;

[0073] Step 305: Send the device control instruction to the target information publishing device.

[0074] Event preprocessing can include steps such as merging identical events and merging event ranges from adjacent sensors. For example, if multiple adjacent sensors detect road congestion, the congestion range can be determined based on the distance between the sensors, ultimately yielding the road segment range involved in the congestion event.

[0075] In one embodiment of the present application, before sending the device control instruction to the target information publishing device in the above steps 104 and 204, it is also possible to detect whether the target information publishing device is a sensitive device, and / or whether the type of the device control instruction is a type that requires manual review. When the target information publishing device is a sensitive device, and / or the type of the device control instruction is a type that requires manual review, the roadside intelligent station sends the device control instruction to the vehicle-road cloud platform for manual review, and after receiving the confirmation sending instruction sent by the vehicle-road cloud platform, the device control instruction is sent to the target information publishing device, so that the content published by sensitive devices (for example, information boards) are all manually reviewed content, and the content that requires manual review before being broadcast has been manually reviewed before being broadcast, thereby improving the quality of information release.

[0076] In an embodiment of the present application, when the target information release device is a vehicle-mounted unit, the roadside intelligent station can first send the device control instruction to the roadside unit, and the roadside unit sends the device control instruction to the vehicle-mounted unit, and then the vehicle-mounted unit broadcasts the information based on the device control instruction.

[0077] In one embodiment of the present application, after sending the device control instruction to the target information publishing device, it is also possible to receive control result feedback data sent by the target information publishing device, and send the control result feedback data to the vehicle-road cloud platform, so that the vehicle-road cloud platform can optimize subsequent management and control strategies (for example, modify the plan content) based on the feedback data, form a closed-loop management, and improve the management and control effect.

[0078] In an embodiment of the present application, when the target information release device is an information release device with relatively simple functions such as a tweeter, an induction light, a variable speed limit sign or an information board, it can be determined that the target information release device is still online after the device control instruction is sent, or when the control result feedback data sent by the target information release device is received, it is determined that the target information release device has released information based on the device control instruction; otherwise, it is determined that the target information release device has not released information based on the device control instruction.

[0079] In one embodiment of the present application, after sending the device control instruction to the target information publishing device, it is also possible to receive a modification instruction for the publishing content of the target information publishing device sent by the vehicle-road cloud platform. Based on the modification instruction, the publishing content of the target information publishing device is modified, thereby realizing flexible control of the information publishing device.

[0080] Combined with the descriptions of the above-mentioned embodiments, the control method for the information release device provided in the embodiment of the present application is compared with the traditional control method for implementing the information release device using fixed strategies. The present application avoids the problem of excessive increase in the number of fixed strategies through a flexible plan matching mechanism, thereby reducing the management burden of the information release device. In addition, the problem of road managers having difficulty in flexibly and quickly adding, deleting, and modifying management strategies due to the excessive increase in the number of fixed strategies, and being unable to adapt to changing traffic conditions in a timely manner, and being unable to accurately perform personalized equipment control and information broadcasting based on real-time complex road conditions, diverse weather conditions, and various events will not occur. In addition, the present application also improves the control effect by establishing a feedback mechanism.

[0081] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations. However, those skilled in the art should be aware that this application is not limited to the described order of actions. In some embodiments of this application, certain steps may be performed in other orders.

[0090] In one embodiment of the present application, the above-mentioned control unit 505 is also used to detect whether the target information publishing device is a sensitive device, and / or whether the type of the device control instruction is a type that requires manual review; if the target information publishing device is a sensitive device, and / or the type of the device control instruction is a type that requires manual review, the device control instruction is sent to the vehicle-road cloud platform, and after receiving the confirmation sending instruction sent by the vehicle-road cloud platform, the device control instruction is sent to the target information publishing device.
