[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] The countdown signal light error correction method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed in the cloud or on another network server. Server 104 determines the update time of the target traffic light's learning program parameters, wherein the target traffic light operates with a learning countdown program. Before the update time, server 104 sends an interference pulse signal to the target traffic light to cause it to disable the learning countdown program and switch to a pulse-type countdown program. After the update time, server 104 switches the target traffic light back to the learning countdown program so that it operates under the updated learning program parameters. Terminal 102 is a traffic light device, and server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0045] In one exemplary embodiment, such as Figure 2 As shown, a countdown signal light error correction method is provided, which is applied to... Figure 1 Taking server 104 as an example, the explanation includes the following steps 202 to 206. Wherein:

[0046] Step 202: Determine the update time of the target traffic light learning program parameters, wherein the target traffic light operates with a learning countdown program.

[0047] The working principle of a learning-type countdown traffic light is to achieve countdown control through learning. Generally, learning a countdown requires two operating cycles: the first cycle for learning and the second cycle for calibration. Once calibration and matching are achieved, countdown control begins in the third cycle. For different time periods, due to varying traffic conditions, the learning program parameters for the learning-type traffic light also differ. When the traffic light program switches, the new learning program parameters must be applied. Besides learning-type countdown traffic lights, there are also pulse-type countdown traffic lights. Pulse-type countdown traffic lights are controlled by receiving pulse signals from a host computer. If the traffic light is operating under a pulse-type countdown program, it will flash briefly upon receiving a pulse signal, and the countdown will begin simultaneously with the flashing of the traffic light.

[0048] However, due to the learning-based countdown traffic lights' learning mechanism, updates to the learning program parameters can lead to display errors. For example, an update might lengthen the red light duration, causing the light to remain red until the countdown reaches its end. Vehicles seeing the countdown end might then begin to move, potentially causing collisions with other vehicles traveling in the same direction and resulting in accidents. Alternatively, an update might shorten the green light duration, causing an incorrect countdown. The green light might switch to yellow before the final moment, leading to driver misjudgment and sudden braking, resulting in rear-end collisions.

[0049] The target traffic light represents the traffic light that requires error correction control. In this embodiment, the target traffic light for error correction is a learning countdown traffic light, operating under a learning countdown program. The update time is the moment when the target traffic light needs to adjust its learning program parameters. The update time can be determined based on a pre-set target traffic light control strategy, or a regular time interval can be set for error correction control of the target traffic light. This embodiment performs error correction control on the target traffic light when it updates its learning level parameters, ensuring that the target traffic light does not malfunction and improving its reliability.

[0050] Step 204: Before the update time, send an interference pulse signal to the target traffic light so that the target traffic light turns off the learning countdown program and switches to the pulse countdown program.

[0051] Since most learning traffic lights have intermittent pulse functionality, this application sends an interference pulse signal before the target traffic light updates its learning program parameters to disrupt its learning program and disable its learning function. When the target traffic light disables its learning function, it can switch to a pulse-type countdown program.

[0052] Step 206: After the update time, switch the target traffic light back to the learning countdown program so that the target traffic light operates under the updated learning program parameters.

[0053] After the learning program parameters are updated, the target traffic light is controlled to work under the learning countdown program again. At this time, the target traffic light works under the updated learning program parameters, that is, it relearns according to the updated learning program parameters, and controls the display of the target traffic light according to the learning results.

[0054] In the aforementioned countdown traffic light error correction method, when the target traffic light is operating in a learning countdown program, the update time of the target traffic light's learning program parameters is first determined. Before the update time, an interference pulse signal is sent to the target traffic light to cause it to shut down the learning countdown program and switch to a pulse countdown program. After the update time, the target traffic light is switched back to the learning countdown program so that it operates under the updated learning program parameters. The countdown traffic light error correction method of this application utilizes the pulse function of the countdown traffic light. Before the target traffic light is about to undergo a program update (i.e., before adjusting the learning program parameters), an interference pulse signal is sent to the target traffic light to disrupt its current pulse rhythm, causing it to shut down its current learning program and switch to a pulse countdown program. This continues until new learning program parameters are received, after which the target traffic light readjusts to the learning countdown program and relearns and runs according to the updated parameters. This avoids display errors caused by learning program parameter updates, reduces road traffic accidents, and improves road traffic safety.

[0055] In a further embodiment, sending an interference pulse signal to the target traffic light before the update time includes: setting the working period before the update time as an error correction period, and sending a number of interference pulse signals during the error correction period, wherein the interference pulse signal is a recognizable pulse signal of the target traffic light.

[0056] As mentioned earlier, generally speaking, learning traffic lights require several cycles to learn new learning program parameters after receiving them. Therefore, this embodiment sends an interference pulse signal before updating the learning program parameters to disrupt the target traffic light's operating cycle, causing it to shut down the learning countdown program and preventing the target traffic light from incorrectly learning the updated parameters, thus avoiding errors.

[0057] Furthermore, during the error correction period, several interference pulse signals are sent to the target traffic light. These interference pulse signals are pulse signals that the target traffic light can recognize, so that the target traffic light can be affected by the interference pulse signals, thus ensuring that the working cycle of the target traffic light is interfered with.

[0058] In an exemplary embodiment, the error correction period includes at least two working cycles, and the method further includes: setting the penultimate working cycle before the update time as the first error correction cycle, and setting the last working cycle before the update time as the second error correction cycle; sending a first interference pulse signal in the first error correction cycle, and sending a second interference pulse signal in the second error correction cycle.

[0059] For example, if a target traffic light needs two operating cycles to learn new learning program parameters, this embodiment sets two consecutive operating cycles as error correction periods. For ease of control, this embodiment selects the two operating cycles preceding the update of the learning program parameters as the error correction periods. The error correction periods include a first error correction cycle and a second error correction cycle that are sequentially consecutive. Interference pulse signals are sent to both error correction cycles to interfere with the current operating program of the target traffic light, causing it to shut down the learning countdown program. Furthermore, to ensure successful interference, the interference pulse signals sent between the two error correction cycles can be sent arbitrarily without any pattern.

[0060] In one embodiment, transmitting a first interference pulse signal during a first error correction period includes: during the first error correction period, at a first moment when the target traffic light displays the first phase, transmitting a first interference pulse signal, wherein the first interference pulse signal is a red light pulse signal that is different from other traffic lights.

[0061] In this context, "phase" represents the direction displayed by the target traffic light, such as a straight-ahead phase, a left-turn phase, a right-turn phase, etc. Generally, a complete cycle of all phases of the target traffic light is called one working cycle of the target traffic light. In this embodiment, when sending the first interference pulse signal during the first error correction cycle, the first interference pulse signal can be sent at the first moment of the first phase displayed by the target traffic light. There is no restriction on the setting of the first moment; it can be any moment within the first error correction cycle.

[0062] For ease of control, in this embodiment, the first interference pulse signal sent in the first error correction cycle is the red light pulse signal of another traffic light. When the target traffic light recognizes the red light pulse signal of another traffic light, it will affect the learning program of the target traffic light and thus interfere with the working cycle of the target traffic light.

[0063] In another embodiment, the interference pulse signal includes a green light interference pulse signal and a red light interference pulse signal. Sending the second interference pulse signal during the second error correction period includes: sending the green light interference pulse signal and the red light interference pulse signal respectively during the second error correction period.

[0064] For example, for the interference pulse signal of the second error correction cycle, a green light interference pulse signal and a red light interference pulse signal can be sent sequentially.

[0065] Furthermore, in one embodiment, sending a green light interference pulse signal and a red light interference pulse signal respectively includes: sending a green light interference pulse signal at a second moment when the target traffic light is displayed as a green light, and sending a red light interference pulse signal at a third moment when the target traffic light is displayed as a red light.

[0066] The second moment is any time when the target traffic light is green, and the third moment is a period of time before the target traffic light turns red, such as 0.6 seconds before the target traffic light turns red. Interference pulse signals are sent at any time to irregularly send interference pulse signals to the target traffic light, causing the target traffic light to shut down its learning countdown program and switch to a pulse-type countdown program after being interfered with.

[0067] In this embodiment, before the target traffic light updates its learning program parameters, irregular interference pulse signals are sent to the target traffic light to keep it connected to the learning program before the parameter update. This prevents prior operating data from affecting the learning process after the parameter update, avoids errors when updating the learning program parameters, improves the stability of the target traffic light's operation, reduces the occurrence of road traffic accidents, and enhances road traffic safety.

[0068] like Figure 3 As shown, in an exemplary embodiment, a countdown signal light error correction method is provided, including steps 302 to 310. Wherein:

[0069] Step 302: Determine the update time of the target traffic light learning program parameters.

[0070] The target traffic light is currently operating with a learning countdown program.

[0071] Step 304: Set the second-to-last working cycle before the update time as the first error correction cycle. Within the first error correction cycle, at the first moment when the target traffic light displays the first phase, send the first interference pulse signal. The first interference pulse signal is the red light pulse signal of other traffic lights.

[0072] The first moment is any moment when the target signal light displays the first phase.

[0073] Step 306: Set the last working cycle before the update time as the second error correction cycle. In the second error correction cycle, at the second moment when the target traffic light is displayed as green, send a green light interference pulse signal, and at the third moment when the target traffic light is displayed as red, send a red light interference pulse signal.

[0074] The second moment is any moment when the target traffic light displays green, and the third moment is 0.6 seconds before the target traffic light turns red. The green and red interference pulse signals sent during the second error correction cycle are both identifiable pulse signals corresponding to the target traffic light.

[0075] Step 308: The target signal light shuts down the learning countdown program and switches to the pulse countdown program. After the update time, the target signal light receives the updated learning program parameters and switches back to the learning countdown program to learn according to the updated learning program parameters.

[0076] Step 310: The target traffic light displays normally after the updated learning program parameters are applied.

[0077] This application addresses the shortcomings of learning countdown timers when switching learning program parameters for target traffic lights, preventing traffic accidents caused by drivers being misled by countdown display errors. The aim is to provide a method for promptly shutting down the learning countdown display before errors occur, thereby reducing road traffic accidents and improving road safety.
