[0002] With the emergence of applications such as industrial Internet, telemedicine, and driverless cars, the requirements for networks have also shifted from non-determinism to determinism. From the perspective of industry trends and technological evolution, deterministic networks are the main evolution direction of future communication networks. Deterministic scheduling is a key technology in system design, which ensures the predictability and stability of the system by precisely controlling the time and order of task execution.
[0003] However, the bandwidth utilization rate of the current gating mechanism is low. This is because if the bridge or end device does not use the time slots in the gating mechanism in time, these time slots and bandwidth will be lost, resulting in low utilization of network bandwidth. Furthermore, when the traffic and number of time slots in the network increase significantly, the gating list solution is complex and time-consuming, and it is impossible to ensure that the gating list can be solved quickly, thus affecting the response speed and efficiency of the network.

[0060] See also Figure 1 , Figure 1 1 is a schematic diagram of an application environment provided by an embodiment of the present application, including an information detection device 101 and a vehicle-mounted server 102. The information detection device 101 and the vehicle-mounted server 102 are connected to each other through a wired link or a wireless link, which is not limited in the present application.
[0061] In a possible embodiment, in order to detect relevant information about the vehicle itself and its surroundings, the information detection device 101 provided on the vehicle may include a speed detection device, a position detection device, an environment detection device, and the like.
[0062] Specifically, in a possible embodiment, the speed detection device can be used to detect the speed of the vehicle itself, and can be used to detect the speed of surrounding vehicle obstacles.
[0063] Among them, the speed detection device for detecting the speed of the vehicle may be specifically configured as a wheel speed sensor installed on the wheel axle, which calculates the driving speed of the vehicle by detecting the rotation speed of the wheel. It can also be configured as an inertial measurement unit or other device to obtain the driving speed of the vehicle through calculation and deduction.
[0064] The speed detection device for detecting the speed of surrounding vehicle obstacles may be specifically configured as one or more of a radar speed measurement device that measures the speed of a vehicle by sending a radio frequency signal and receiving its reflection, a laser speed meter that uses a laser beam to measure the speed of a vehicle, and an image speed detection device that uses computer vision technology to analyze the movement of the vehicle to estimate the speed of the vehicle. These speed detection devices can be used alone or in combination to provide accurate measurement of the speed of surrounding vehicles.
[0065] In a possible embodiment, the position detection device may be specifically configured as one or more of a radar sensor that determines the position of the vehicle by sending radio waves and receiving their reflections, an ultrasonic sensor that determines the position of the vehicle by sending ultrasonic pulses and measuring their return time, and a camera sensor. Furthermore, the exchange of position and other status information between vehicles can be achieved through on-board communication technologies such as on-board communication modules and vehicle-to-vehicle communication standards (such as vehicle networking technology), thereby realizing the detection and tracking of the position of the vehicle itself and surrounding vehicles.
[0066] In a possible embodiment, the environment detection device may be specifically configured as an image acquisition device such as a camera, which continuously captures images or videos around the vehicle through the camera, and then subsequently identifies objects in the images or videos through object detection or object recognition technology. For example, it can identify whether it is a car, truck or pedestrian, as well as their speed, direction, etc., and can further analyze the current environment of the vehicle, such as a parking lot, highway, etc.
[0067] In a possible embodiment, the vehicle-mounted server 102 is used to receive speed information, location information, direction information, and environmental information detected by the information detection device 101, and determine the current working mode of the vehicle; determine the target gating mechanism corresponding to the current working mode; the target gating mechanism represents the time distribution mechanism of the vehicle's traffic in the current working mode; obtain the current time of the system, the first gating cycle of the current gating mechanism, and the first gating start time; determine the gating switching time according to the current time of the system, the first gating cycle, and the first gating start time; switch to the target gating mechanism according to the gating switching time. The present application determines the corresponding gating mechanism based on the working mode of the vehicle system, reduces the number of traffic and time slots processed by the server in each working mode, and significantly reduces the complexity of solving the gating table. At the same time, the working mode corresponds to the time slot of the gating mechanism, so that the time slot can be effectively utilized, improving the bandwidth utilization of the network link.
[0068] The following describes a specific embodiment of a gated switching method of the present application. Figure 2 This is a schematic diagram of a gated switching method provided in an embodiment of the present application. Figure 1 , this specification provides method operation steps such as embodiments or flow charts, but may include more or fewer operation steps based on routine or non-creative work. The order of steps listed in the embodiments is only one way of executing the steps among many orders, and does not represent the only order of execution. When the actual system or server product is executed, it can be executed in the order of the method shown in the embodiments or the drawings or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, Figure 2 As shown, it may include:
[0069] S201: Determine the current operating mode of the vehicle.
[0070] S202: Determine a target gating mechanism corresponding to the current working mode; the target gating mechanism represents a time distribution mechanism of vehicle flow in the current working mode.
[0071] S203: Acquire the current time of the system, the first gating cycle of the current gating mechanism, and the first gating start time.
[0072] S204: Determine a gating switching time according to the current system time, the first gating cycle and the first gating start time.
[0073] S205: Switch to the target gating mechanism according to the gating switching time.
[0074] Figure 3 This is a schematic diagram of a gated switching method provided in an embodiment of the present application. Figure 2 , the method may include:
[0075] S301: Determine the current operating mode of the vehicle.
[0076] In a possible embodiment, the current working mode includes at least one of a forward mode, a deceleration mode, a reverse mode, and a parking mode. Specifically, the forward mode indicates that the vehicle is currently in a normal driving state, and is driving within a set speed range or speed limit; the deceleration mode indicates that the vehicle is currently decelerating or needs to reduce speed to adapt to specific road conditions or environmental conditions. The vehicle switches to the deceleration mode when there are obstacles ahead, the road conditions are complex, or emergency braking is required; the reverse mode indicates that the vehicle is currently driving backwards, and is usually used for parking, backing up to adjust the position, or other operations that require moving backwards. In the reverse mode, the vehicle may be limited by the field of vision and the controller, and special attention needs to be paid to surrounding obstacles and safety distances; the parking mode is an auxiliary mode when the vehicle is parking, usually with the help of auxiliary equipment such as reversing radar and cameras to assist the driver in precise parking operations.
[0077] According to the specific meaning of the above working modes, in different vehicle working modes, the data and information that the vehicle relies on are different. As a key mechanism for controlling network data transmission, the gated list also needs to change dynamically according to changes in the working mode.
[0078] For example, in forward mode, there may be more sensor data that needs to be transmitted, while in deceleration or reverse mode, the data flow of control signals may increase. Therefore, the gating list needs to be dynamically adjusted according to the different working modes to optimize the use of network resources, avoid congestion and delay of information and data, and meet the requirements of real-time and security.
[0079] In a possible embodiment, determining the current working mode of the vehicle includes:
[0080] S3011: Obtain the vehicle's driving speed information, driving direction information and driving environment information.
[0081] S3012: Determine the current working mode based on the driving speed information, driving direction information and driving environment information.
[0082] The driving speed information represents the current driving speed of the vehicle and can be obtained through the speed sensor or the engine control unit of the vehicle. The driving speed information is used to determine what speed range the vehicle is in. For example, when the vehicle is in a low speed range, the vehicle is usually in parking mode or deceleration mode; when the vehicle is in a medium speed range, the vehicle is usually in normal driving state, forward mode; when the vehicle is in a high speed range, the vehicle is usually in forward mode, but it needs to be further determined in combination with environmental factors.
[0083] The driving direction information represents the current driving direction of the vehicle, including forward, reverse, turning and other states, which can be obtained through the steering wheel angle sensor or the vehicle's direction sensor.
[0084] The driving environment information represents the surrounding environment of the vehicle, including road conditions, surrounding obstacles, weather conditions, etc. The above driving environment information can be obtained through cameras, radars, laser radars, road sensors, etc. The driving environment information is used to further determine the current working mode of the vehicle.
[0085] In the embodiment of the present application, each working mode has its own driving speed information, driving direction information and driving environment information, which constitutes a mapping relationship table between working modes and driving information, for example, "if the speed is extremely low or close to stopping, the direction is any direction, and the surrounding environment is a parking area, the corresponding parking mode". If the driving information of the current vehicle matches a mapping relationship in the mapping relationship table, then the current working mode is the working mode corresponding to the mapping relationship.
[0086] By comprehensively analyzing the above driving information, the vehicle can accurately determine its working mode in real time to determine the gating list that adapts to the current driving situation and environmental conditions to ensure driving safety and efficiency.
[0087] S302: Determine a target gating mechanism corresponding to the current working mode.
[0088] In a possible embodiment, determining a target gating mechanism corresponding to the current working mode includes:
[0089] S3021: Obtain the current gate control identifier corresponding to the current working mode.
[0090] S3022: Obtain a gating table set.
[0091] Optionally, the gating table set includes multiple gating tables.
[0092] In the embodiment of the present application, the gating table set includes four gating tables, corresponding to the forward mode, the deceleration mode, the reverse mode and the parking mode, respectively. Furthermore, the gating identifiers of the four gating tables are "SET0", "SET1", "SET2" and "SET3". It should be clear that if the working mode of the vehicle is further subdivided, more one-to-one corresponding gating tables need to be set. This application only takes four gating tables as an example for explanation.
[0093] S3023: If the current gating identifier exists among the gating identifiers of the multiple gating tables, determine that the gating table corresponding to the current gating identifier is the target gating mechanism corresponding to the current working mode.
[0094] In a possible embodiment, since the gating table is pre-configured and corresponds to the working mode one by one, there is no situation where the current gating identifier does not exist in the gating identifiers of multiple gating tables.
[0095] In a possible embodiment, configuring the gating table requires configuring the various time windows and queue states, gating cycles, and gating opening times of the gating table. Specifically, a time window refers to a specific time period within a gating cycle, during which the gating list controls the open or closed state of a specific queue. The queue state refers to whether a specific data queue is in an open state (Open) or a closed state (Close) within a certain time window. If it is in an open state, data packets in the queue can be sent within the time window. If it is in a closed state, data packets in the queue cannot be sent within the time window. The gating cycle T is the cycle period of the gating list, which defines the time period of the entire gating operation. The gating opening time refers to the time point when the gating table starts to execute.
[0096] In a possible embodiment, when switching the gating table, it is necessary not only to determine which gating table to switch, but also to determine when the gating table starts working, so as to ensure that the gating table starts working at an appropriate time point to avoid interruption of data transmission or time synchronization errors.
[0097] S303: Acquire the current time of the system, the first gating cycle of the current gating mechanism, and the first gating start time.
[0098] S304: Determine a gating switching time according to the current system time, the first gating cycle and the first gating start time.
[0099] In a possible embodiment, the current time of the system is the current value of a system clock or a network synchronization clock.
[0100] In the embodiment of the present application, the first gating period T of the current gating mechanism cycle is 2000μs, the first gate opening time T gate opening is 5000μs, indicating that the current gating table starts executing at 5000 microseconds. The current time of the system is T current is 10500μs.
[0101] In order to ensure that the new gating table switches exactly at the beginning of the next cycle, it is necessary to calculate how many complete cycles have passed between the current time point and the gating opening moment, that is, how many cycles are required from the current moment to the next global working window.
[0102] In the embodiment of the present application, the time difference between the current time of the system and the first gate opening time is first calculated, that is, T current -T gate opening Then, divide this time difference by the first gating period T cycle, a decimal or integer is obtained, which represents how many cycles have been experienced from the start time to the current time. Finally, the decimal is rounded up to ensure that the calculation result is an integer, representing the number of complete cycles n, in this application n = 3.
[0103] After the cycle number is calculated, the sum of the system current time and the product of the cycle number and the first gate control cycle is T current +n×T cycle That is the gate switching time T switch In this application T switch =11000μs.
[0104] S305: Switch to the target gating mechanism according to the gating switching time.
[0105] The above calculation method can ensure that when a new gating table is switched, the previous gating table has been run to completion, and the new gating table starts from a complete cycle instead of switching in the middle of a cycle, thereby avoiding uncertainty in data transmission.
[0106] Figure 4 This is a flow chart of a method for determining a gate switching mode provided in an embodiment of the present application. Figure 1 , the method may include:
[0107] S401: Acquire the current entry content of the current gating table and the target entry content of the target gating table.
[0108] S402: Determine whether the target entry content includes the current entry content, if so, execute S403; if not, execute S404.
[0109] In a possible embodiment, the target gating table adds a new entry after the current entry content of the current gating table to form the target entry content.
[0110] In this case, it is possible to immediately switch to the target gating table at the gating switching moment.
[0111] In other possible embodiments, the target gating table is not formed by adding a new entry after the current entry content of the current gating table. In this case, it is necessary to switch according to the preset delay time to ensure that the start time of the new gating table is aligned with the global working window, thereby avoiding inconsistencies or delays in data transmission.
[0112] S403: At the gating switching moment, switch to the target gating table.
[0113] S404: Obtain the second gating opening time of the target gating table.
[0114] S405: Determine a gating switching mode according to the first gating cycle, the first gating start time and the second gating start time.
[0115] In a possible embodiment, the gated switching mode further includes a first delayed switching mode and a second delayed switching mode.
[0116] In one possible embodiment, Figure 5 This is a flow chart of a method for determining a gate switching mode provided in an embodiment of the present application. Figure 2 ,like Figure 5 As shown, the method for determining the gate switching mode includes:
[0117] S4051: Determine a time interval according to a difference between the first gated-on time and the second gated-on time.
[0118] In the embodiment of the present application, the first gated opening time of the current gated table is 5000 μs, and the second gated opening time of the target gated table is 8000 μs, then the time interval is the difference between the first gated opening time and the second gated opening time, 3000 μs.
[0119] S4052: Determine whether the time interval is equal to an integer multiple of the first gating period, if so, execute S4053; if not, execute S4054.
[0120] S4053: Determine that the first delayed switching mode is the current gated switching mode.
[0121] S4054: Determine that the second delayed switching mode is the current gated switching mode.
[0122] In the embodiment of the present application, if the first gating cycle is 3000 μs, then the time interval 3000 μs is equal to an integer multiple of the first gating cycle 3000 μs, and the first delay switching mode is determined to be the current gating switching mode. If the first gating cycle is 2000 μs, then the time interval 2000 μs is not equal to an integer multiple of the first gating cycle 3000 μs, and the second delay switching mode is determined to be the current gating switching mode.
[0123] In the embodiment of the present application, the first delayed switching mode is characterized by being aligned with the second gating start time of the target gating table after the first gating cycle of the current gating table ends.
[0124] In the embodiment of the present application, the second delayed switching mode is characterized by that after the first gating cycle of the current gating table ends, the current time is not aligned with the second gating start time of the target gating table, and adjustment is required to start the target gating table to work.
[0125] S406: Obtain a preset delay time.
[0126] S407: Determine the delayed current system time and the delayed gated switching time according to the preset delay time and the current system time, and use the delayed gated switching time as the gated switching time.
[0127] S408: Switch to the target gating table according to the gating switching mode and the gating switching time.
[0128] In a possible embodiment, a preset delay time Tdelay is obtained, and a waiting time Tdelay is used based on the system current time Tcurrent. The delayed system current time Tcurrent+Tdelay is used as the system current time Tcurrent to calculate the gate switching time Tswitch. Then, based on a specific gate switching mode, the gate switching time Tswitch is waited for.
[0129] In a possible embodiment, if the gating switching mode is the first delayed switching mode, at the gating switching time, the target gating table is switched.
[0130] In another possible embodiment, if the gating switching mode is the second delayed switching mode, the execution state of the current gating table is acquired.
[0131] In a possible embodiment, if the execution status indicates that the current cycle task of the current gating table has been completed, an idle cycle is inserted, and the target gating table is switched at the gating switching time. The idle cycle means that the current task has been completed, but before the gating switching time arrives, the system does not perform any new tasks and is only in a waiting state. When the gating switching time arrives, it immediately switches to the target gating table. Since the current cycle task of the current gating table has been completed and the system is in an idle state, the switching process can proceed smoothly.
[0132] In another possible embodiment, if the execution status indicates that the current cycle task of the current gating table is not completed, the current gating table executes the current cycle task and switches to the target gating table at the gating switching time.
[0133] Through the above process, the system can smoothly and effectively switch to the target gating table to maintain the stability of the network and the continuity of the task.
