[0002] Traffic signal control systems are an important component of intelligent transportation. By using traffic signal control systems, traffic flow can be effectively managed and the smooth flow of traffic on urban roads can be improved.

[0003] To obtain various advanced road traffic management solutions and achieve real-time traffic flow data collection and optimized timing control through traffic signal control systems to reduce vehicle congestion, it is typically necessary to deploy a corresponding number of devices to generate signal phase data to support various scenarios such as development or demonstration. This requires powering on, configuring, and testing the devices until they are operating normally and producing real data. Only after a series of complex and correct operations and configurations can the corresponding application scenarios be ultimately supported. Furthermore, in actual operation, equipment failures, configuration errors, and other factors may occur, preventing development, testing, and demonstration activities from proceeding normally. Summary of the Invention

[0004] This invention provides a method and system for simulating traffic signal phase data, which can efficiently and stably support signal control-related application scenarios such as signal research and development, testing, demonstration, and stress testing.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0033] Example 1

[0034] Figure 1 This is a flowchart illustrating a method for simulating traffic signal phase data according to Embodiment 1 of the present invention. This embodiment is applicable to simulating traffic signal phase data. The method can be executed by a traffic signal phase data simulation device, which can be implemented in hardware and / or software. This traffic signal phase data simulation device can be configured in any electronic device with network communication capabilities. Figure 1 As shown, the method may include:

[0035] S110. Trigger at least one signal machine simulation task request through the front-end device, and transmit the triggered at least one signal machine simulation task request to the back-end device.

[0036] Specifically, at least one triggered signal simulating task request is determined from the front-end device's memory. The signal simulating task request send start button is clicked, and the triggered signal simulating task request is sent to the back-end device through the front-end push data interface.

[0037] For example, at least one signal machine to be pushed is selected from the data list stored in the front-end storage. The front-end calling program adds the signal machine to be pushed to the data push queue of the push data interface. The front-end push data interface sends the signal machine simulation task request data to the back-end device in the first-in-first-out order of the queue storage.

[0038] S120. Based on at least one signal simulation task request sent by the front-end device, the back-end device executes the signal simulation task to generate the corresponding signal phase timing data.

[0039] Specifically, after receiving at least one signal simulation task request sent by the front-end device, the back-end device puts at least one signal simulation task request into the cache, executes the signal simulation task request, and generates the corresponding signal phase timing data.

[0040] For example, the backend device will receive the signal simulator task request data sent by the frontend device, store the data in the backend cache, and start a push thread to push at least one signal simulator task request. The backend device will traverse the list of signal simulator task request data to be pushed and assemble it into the corresponding signal phase timing data.

[0041] S130. The back-end device generates simulated signal light change data based on the signal phase timing data.

[0042] Specifically, the backend equipment determines whether the current signal phase timing data has changed phase. If the signal phase timing data has changed phase, it obtains the current phase number and assembles the signal light change simulation data based on the current phase number.

[0043] For example, the backend device determines whether the current phase timing data of the signal has changed by using a timer and the phase period pattern of the signal. If the phase timing data of the signal has changed, the device determines the current phase number based on the current timer runtime and assembles the signal light change simulation data.

[0044] S140. The signal phase timing data and signal light change simulation data are transmitted from the back-end device to the front-end device for simulation display.

[0045] Specifically, the front-end device acquires the signal phase timing data assembled by the back-end device, generates traffic light change simulation data based on the signal phase timing data, and transmits the signal phase timing data and traffic light change simulation data to the front-end device for simulation display.

[0046] For example, the backend generates traffic light change simulation data from the phase timing data of the signal that has undergone a phase change. Clicking the signal push button pushes the currently assembled signal phase timing data and traffic light simulation data to the frontend device. The push frequency is once per second.

[0047] This application provides a method for simulating traffic signal phase data. A front-end device triggers at least one traffic signal simulation task request, which is then transmitted to a back-end device. The back-end device executes the simulation task based on the request, generating traffic signal phase timing data. A back-end traffic signal simulator then uses this data to generate simulated traffic light change data. Finally, the back-end device transmits both the phase timing data and the simulated traffic light change data to the front-end device for simulation display. This method allows the back-end to quickly generate traffic signal phase timing data and simulated traffic light change data based on the front-end's simulated task request, and displays the phase timing data at the front-end. This method supports simultaneous simulation of single and multiple traffic signals and can quickly and stably simulate traffic signal phase timing data, supporting applications such as traffic signal research and development, testing, demonstration, and stress testing.

[0048] Example 2

[0049] Figure 2 This is a flowchart illustrating a method for simulating traffic signal phase data according to Embodiment 2 of the present invention. This embodiment further refines the front-end device simulation and display steps of the above embodiment. Figure 2 As shown, the method may include:

[0050] S210. Trigger at least one signal machine simulation task request through the front-end device, and transmit the triggered at least one signal machine simulation task request to the back-end device.

[0051] Specifically, determine at least one signal machine simulation task request that needs to be pushed from the data list stored in the front-end device, click the start push button, and transmit at least one signal machine simulation task request to the back-end device.

[0052] Optionally, the trigger signal for at least one signal controller is obtained through the front-end device, and a corresponding signal controller simulation task request is generated based on the triggered signal controller when the back-end device is detected not pushing signal controller phase data.

[0053] For example, the data list of the front-end device records the trigger signal of at least one signal controller control. When the back-end device does not push signal controller phase data, a corresponding signal controller simulation task request will be generated based on each triggered signal controller control.

[0054] S220. Based on at least one signal simulation task request sent by the front-end device, the back-end device executes the signal simulation task to generate the corresponding signal phase timing data.

[0055] As an optional but not limited implementation, performing a signal simulation task to generate the corresponding signal phase timing data may include steps A1-A3:

[0056] Step A1: Generate the first configuration information of the signal by performing a signal simulation task through the signal simulator. The first configuration information includes the signal number and the latitude and longitude of the signal.

[0057] For example, according to S110, based on the trigger signal of at least one signal controller control obtained by the front-end device, a signal controller simulation task request corresponding to the triggered signal controller control is generated. The signal controller simulation task is executed through the signal controller simulator, and the first configuration information of the signal controller is generated by executing the signal controller simulation task, such as... Figure 3 As shown, the first configuration information includes the signal number and the latitude and longitude of the signal.

[0058] Step A2: Generate the second configuration information of the signal by executing the signal simulator. The second configuration information includes the signal phase and the corresponding direction, flow direction, signal mode and signal type.

[0059] For example, according to S110, based on the trigger signal of at least one signal controller control obtained by the front-end device, when the back-end does not push signal controller phase data, the front-end generates a corresponding signal controller simulation task according to the trigger signal of the signal controller control. The signal controller simulator executes the signal controller simulation task to generate the second configuration information of the signal controller, such as... Figure 4 As shown, the second configuration information includes the stage, flow direction, signal mode, and signal type corresponding to the signal phase.

[0060] Step A3: Generate signal phase timing data of the signal machine based on the first configuration information and the second configuration information. The signal phase timing data is used to describe the execution order of the signal machine phases and the duration of different phase stages corresponding to the phases.

[0061] For example, according to steps A1-A2, the first configuration information and the second configuration information are obtained, and the signal phase timing data of the signal is assembled according to the first configuration information and the second configuration information of the signal. The signal phase timing data describes the execution order of the signal phase and the duration of different phase stages corresponding to the phase. The signal phase can be an eight-phase four-stage signal, and the execution order of the signal phase can be the display order of the eight-phase four-stage signal at the traffic intersection. The duration of different phase stages can be the cycle duration of the eight-phase four-stage information cyclically executed at the traffic intersection. When a signal executes the phase timing data, it will specify the green light duration, yellow light duration, red light duration, all-red time, phase description, total cycle duration, maximum green light duration, and minimum green light duration corresponding to a certain phase.

[0062] S230. The back-end device generates simulated signal light change data based on the signal phase timing data.

[0063] For example, the backend receives at least one signal simulator task request sent by the frontend, and the backend generates signal phase timing data based on the signal simulator task request, such as... Figure 5 As shown, the traffic light change simulation data is waiting for the backend to generate based on the traffic light phase timing data.

[0064] As an optional but not limited implementation, generating simulated traffic light change data based on the traffic light phase timing data may include steps B1-B2:

[0065] Step B1: Generate simulated signal light groups corresponding to the signal lights by executing the signal light simulator. Each simulated signal light group includes signal lights for three directions: left turn, straight ahead, and right turn.

[0066] For example, a traffic signal simulator is used to perform a traffic signal simulation task to generate a simulated traffic light group corresponding to the traffic signal. By default, four simulated traffic light groups are generated for each intersection, and each simulated traffic light group generates traffic lights for three directions: left turn, straight ahead, and right turn.

[0067] Step B2: Load the phase timing data of the signal machine into the analog signal light group corresponding to the signal machine, and control the analog signal light group to adjust the light color to obtain analog data of signal light change.

[0068] For example, S220 learns that the signal simulator generates signal phase timing data by performing a signal simulation task, and loads the signal phase timing data into the corresponding simulated signal light group. In this way, the light color adjustment of a certain number signal at a certain station can be specified, and the signal light change simulation data can be obtained. The signal light change simulation data specifies the green light duration, yellow light duration, red light duration, all-red time, phase description, total cycle duration, maximum green light duration, and minimum green light duration for a certain number signal at a certain station.

[0069] S240, Trigger at least one signal controller data push task request by selecting at least one signal controller control on the front-end device.

[0070] Specifically, by clicking the signal push button, the front-end device selects at least one signal control and triggers at least one signal data push task. The front-end calls the push data interface, establishing a channel binding relationship between the front-end device and the back-end device, and sends the signal data push task request to the back-end to prepare to obtain the signal phase timing data and traffic light change simulation data from the back-end. The back-end device then transmits the signal phase timing data and traffic light change simulation data generated by simulating the signal task through the signal simulator to the front-end device.

[0071] S250. Receive the signal data push task request sent by the front-end device through the back-end device, and start the signal data push thread in response to the signal data push task request.

[0072] Specifically, the backend device receives the signal data push task request sent by the frontend device and responds to the signal data push task request. The backend device retrieves the signal to be pushed and the corresponding data of the signal from the cache and starts the signal data push thread.

[0073] S260. The signal phase timing data and traffic light change simulation data are pushed to the front-end device through the signal data push thread, so that the front-end device can perform signal phase simulation display and traffic light change simulation display according to the signal phase timing data and traffic light change simulation data.

[0074] As an optional but not limited implementation, pushing signal phase timing data and traffic light change simulation data to the front-end device through a signal data push thread may include steps C1-C2:

[0075] Step C1: The signal data push thread iterates through the list of signals corresponding to the signal data push task request and assembles the phase timing data and signal light change simulation data of the signals to be pushed.

[0076] Specifically, the signal data push thread starts executing, iterates through the list of signals corresponding to the signal data push task request, and assembles the phase timing data and signal light change simulation data corresponding to the signal to be pushed.

[0077] As an optional but not limited implementation, assembling the signal phase timing data and traffic light change simulation data to be pushed may include steps C11-C12:

[0078] Step C11: Analyze the phase timing data of the signal controller and the simulated data of signal light changes that need to be pushed.

[0079] Specifically, the traffic lights that need to be pushed are identified, and the phase timing data and traffic light change simulation data of the traffic lights that need to be pushed are analyzed.

[0080] Step C12: Based on the analysis results, assemble the signal phase timing data and the traffic light change simulation data into a data structure that the front-end device can recognize.

[0081] Specifically, the signal phase timing data and traffic light change simulation data that generate the analysis results are assembled into a data structure that can be recognized by the front-end equipment.

[0082] Step C2: Push the signal phase timing data and signal light change simulation data to the data channel corresponding to the data push task request established between the front-end device and the back-end device for transmission to the front-end device.

[0083] As an optional but not limited implementation, after pushing the signal phase timing data and traffic light change simulation data to the data channel corresponding to the data push task request established between the front-end and back-end devices, steps C21-C22 may be included:

[0084] Step C21: Obtain signal phase timing data and signal light change simulation data from the data push task request corresponding to the data channel established between the front-end device and the back-end device through the front-end device.

[0085] Specifically, by clicking the signal push button, the front-end device can obtain the phase timing data of the assembled signal and the simulated data of the signal light changes from the channels of the front-end device and the back-end device.

[0086] Step C22: The front-end device draws the signal phase timing diagram and displays the signal light group according to the signal phase timing data and the signal light change simulation data.

[0087] For example, the front-end device acquires assembled data of signal phase timing data and signal light change simulation data, and plots the phase timing diagram of the signal at that station, such as... Figure 4 The display shows the phase timing diagram of the signal lights, and the contents of the phase timing diagram are displayed through the corresponding signal light groups.

[0088] In the implementation of this application embodiment, at least one signal simulation task request is triggered by the front-end device, and the back-end device receives at least one signal simulation task request sent by the front-end. A binding relationship is established between the front-end and back-end channels. The front-end sends a signal data push task request to the back-end. The back-end determines whether there is a signal scheme corresponding to the signal data push task request. If there is such a scheme, the back-end assembles the signal phase timing data and signal light change simulation data into data that the front-end device can recognize. The back-end pushes the assembled data into the data channel between the front-end and back-end. The front-end obtains the assembled data from this data channel and draws the signal phase timing diagram, as well as sets the signal light group to display the phase timing diagram content. The above process is as follows: Figure 6 As shown, Figure 6 This document describes the assembly process of signal phase timing data and traffic light change simulation data, as well as the data interaction process between the front-end and back-end.

[0089] This application provides a method for simulating traffic signal phase data. A front-end device triggers at least one traffic signal simulation task request, which is then transmitted to a back-end device. The back-end device executes the simulation task based on the front-end device, generating traffic signal phase timing data. A back-end traffic signal simulator then uses this phase timing data to generate simulated traffic light change data. Finally, the back-end device transmits both the traffic signal phase timing data and the simulated traffic light change data to the front-end device for simulation display. This method allows the back-end to quickly generate traffic signal phase timing data and simulated traffic light change data based on one or more traffic signal simulation task requests sent by the front-end device, and displays the phase timing data of one or more traffic signals at the front-end. This method supports simultaneous simulation of single and multiple traffic signals and can quickly and stably simulate traffic signal phase timing data, supporting applications such as traffic signal research and development, testing, demonstration, and stress testing.
