Description

Technical Field

[0001] This invention relates to the field of intelligent transportation technology, specifically to a traffic cone guidance indication control method based on a color change control algorithm. Background Technology

[0002] Traffic cones are traffic warning facilities used on roads. Common traffic cones are cone-shaped or cylindrical. They are typically used during road construction, in the event of a traffic accident to alert pedestrians and vehicles, ensuring their safety. They are also used for traffic diversion, and for separating or merging pedestrians and vehicles. Currently, the most common traffic cones are cone-shaped or cylindrical road markings with fluorescent warning colors affixed to them. To increase visibility for drivers, reflective strips are also attached to the outside of the traffic cones.

[0003] Existing traffic cones achieve nighttime traffic warnings by attaching reflective tape. However, without a light source, traffic cones cannot emit light, making them ineffective in warning pedestrians and cyclists, thus limiting their application. More importantly, existing traffic cones only serve a warning function but do not provide guidance or direction for vehicles and pedestrians, leading to traffic congestion and even accidents at accident sites and road construction sites. Furthermore, there are issues with the ability to implement intelligent displays and controls for traffic cones. In addition, there is still significant room for improvement in effectively increasing driver visibility and optimizing the structure of traffic cones.

[0004] Therefore, it is necessary to provide a traffic cone guidance indication control method based on a color change control algorithm to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems of existing traffic cones, such as their inability to provide guidance for vehicle flow and pedestrians, leading to traffic congestion and even traffic accidents at accident sites and road work sites, poor nighttime display effect, and the inability to achieve intelligent display and intelligent control of traffic cones.

[0006] This invention provides a traffic cone guidance indicator control method based on a color change control algorithm. The method includes: initializing various parameters, including color vector information and initial display content of the display screen; inputting the total number of traffic cones and the current traffic cone identifier; determining the color to be displayed for the current traffic cone based on the input total number of traffic cones and the current traffic cone identifier, according to the color change control algorithm; wherein, when a change in the total number of traffic cones is detected, the changed total number of traffic cones is re-inputted; the current cone identifier is re-inputted, and the color to be displayed for the current traffic cone is re-determined based on the changed total number of traffic cones and the current traffic cone identifier.

[0007] According to an optional embodiment of the present invention, determining the color to be displayed by the current traffic cone based on the color change control algorithm includes: determining the color to be displayed by the directional sign on the display screen of the current traffic cone based on the gradient color mapping calculation method, specifically including:

[0008] When the total number of traffic cones in the input traffic cone group is M, and the current traffic cone is identified as N, the color index of the current traffic cone is calculated using the following expression:

[0009]

[0010] Among them, the The color vector is represented by x, where x is the color index; M represents the current traffic cone sign, where M is a positive integer; N represents the current traffic cone sign, where N is a positive integer; and K represents the index of the preset gradient color or color vector, where K is a positive integer.

[0011] According to an optional embodiment of the present invention, the method further includes: identifying each traffic cone based on the total number of traffic cones in the input traffic cone group, and configuring a preset color vector corresponding to each traffic sign; when a change in the total number of traffic cones is detected, reconfiguring the preset color vector corresponding to each traffic sign based on the changed total number of traffic cones.

[0012] According to an optional embodiment of the present invention, color information is read from a preset color vector based on the calculated color subscript of the current traffic cone to determine the color to be displayed on the display screen of the current traffic cone.

[0013] According to an optional embodiment of the present invention, the determined color to be displayed by the directional sign is filled into the filling space of the directional sign for color display, wherein the color to be displayed is a gradient color.

[0014] According to an optional embodiment of the present invention, the guide mark is a mark strip with a bend. The guide mark is formed by translating a first line segment and a second line segment, which are formed by a starting point, a bend point, and an end point, a designated distance along the horizontal direction of the display screen to form a mark strip with a filled space. The mark strip includes a first segment and a second segment that extend obliquely from the bend, and the first segment and the second segment correspond to the first line segment and the second line segment, respectively.

[0015] According to an optional embodiment of the invention, there are two or more guide signs.

[0016] According to an optional embodiment of the present invention, the method further includes determining the color to be displayed in the background of the current traffic cone display screen, and further includes: monitoring the light intensity and determining whether the monitored light intensity is greater than a set threshold, so as to determine the background of the current traffic cone display screen.

[0017] According to an optional embodiment of the present invention, when the monitored light intensity is greater than the set threshold, the background color of the current traffic cone display screen is determined to be white; when the monitored light intensity is less than or equal to the set threshold, the background color of the current traffic cone display screen is determined to be black.

[0018] According to an optional embodiment of the present invention, the color to be displayed on the directional sign in the current traffic cone display screen is determined according to a color change control algorithm; and the color display of the current traffic cone display screen is controlled according to the determined color to be displayed on the directional sign in the display screen and the determined background color of the display screen.

[0019] Beneficial effects

[0020] Compared with existing technologies, this invention initializes various parameters, inputs the total number of traffic cones and the current traffic cone identifier, and directly runs the device according to the color change control algorithm. This allows for a more intelligent and accurate determination of the color to be displayed for the current traffic cone and the colors to be displayed for all traffic cones. It also enables more intelligent control of the traffic cone's directional display, providing guidance for vehicle flow and pedestrians. This effectively avoids traffic congestion or even traffic accidents caused by the inability to provide guidance and direction for vehicles and pedestrians.

[0021] Furthermore, optimal display results can be achieved by setting the directional signs as sign strips with bends.

[0022] Furthermore, by calculating the color index of the current traffic cone through a color change control algorithm to determine the color of the directional sign to be displayed on the screen, and by monitoring the light intensity to determine whether the monitored light intensity is greater than a set threshold, the background of the display screen on the current traffic cone can be determined. This allows for more precise control of the color display on the current traffic cone, which not only further realizes intelligent control and display, but also effectively avoids the problem of poor display effect of traffic cones at night.

It can more intelligently and accurately determine the color to be displayed for the current traffic cone and the colors to be displayed for all traffic cones.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0039] Example 1

[0040] The following will refer to Figures 1 to 6 This invention describes an embodiment of the traffic cone guidance indication control method based on a color change control algorithm.

[0041] An example structure of a smart traffic cone in this embodiment includes: a chassis, a cone located above the chassis, a warning light located above the cone, and a guide indicator module installed on the side of the cone, the guide indicator module having a guide indicator function. The cone is fixed to the chassis by snap-fit, or optionally by screws. The guide indicator module includes a built-in controller and a display screen connected to the controller. Multiple reflective strips may be installed on the outer side of the cone. A warning light is located at the top of the cone, either fixedly or rotatably. The multiple reflective strips are evenly distributed above or below the display screen of the guide indicator module. The warning light consists of tri-color LEDs and is connected to the cone, for example, by a connector. After being electrically connected to the controller of the guide indicator module, the warning light receives electrical signals from the controller and generates a corresponding lighting pattern. When powered on and in working condition, for example, the warning light responds to the received electrical signal by illuminating or flashing colored lights to remind or warn vehicles or pedestrians of a construction area. There are no particular restrictions on the location of multiple reflective strips, as long as they are outside the display screen. The number of reflective strips can be three, four, or more.

[0042] Furthermore, the controller of the intelligent traffic cone's guidance indicator module, in addition to being connected to the display screen, is also electrically connected to other structures and modules of the guidance indicator module to transmit electrical signals. Similarly, the controller is also electrically connected to the cone to transmit electrical signals, and then electrically connected to the warning lights to transmit electrical signals. The guidance indicator module includes a controller, such as a built-in microcontroller, and a display screen connected to the controller; alternatively, the controller is a microcontroller built into the cone and electrically connected to the display screen of the guidance indicator module. The guidance indicator module has guidance indication functions, such as displaying different indicator color symbols fixed on the display screen for different types of traffic cones. For example, when the controller is electrically connected to the display screen in the working state, the controller sends an electrical signal to the display screen, and the display screen receives the electrical signal and generates a corresponding working state, such as displaying different indicator color symbols for different traffic cones. Preferably, different dynamically changing indicator colors are set for different traffic cones according to the guidance indicator color control algorithm, such as... Figure 1 As shown.

[0043] Furthermore, the guidance indicator module also includes a structure capable of electrical connection and signal transmission, mainly comprising: a sensing device, a microcontroller as the controller, a switch, and a microcontroller, etc. The sensing device, for example, is a photosensitive sensor. This sensor detects and monitors environmental and personnel information, transmitting this information via electrical signals to the electrically connected microcontroller. Upon receiving the signal, the microcontroller sends a corresponding control signal to a warning light electrically connected to it. The warning light receives the control signal and generates a periodic or intermittent flashing state corresponding to the control signal. Furthermore, the microcontroller can also send the corresponding control signal to the display screen of the guidance indicator module, which is electrically connected to it. The display screen receives the control signal and generates a corresponding display state, such as a background color with a clearly defined indicator corresponding to the control signal. Here, the controller is a microcontroller, but it is not limited to this. In other embodiments, the controller and the microcontroller can be two independent controllers. The above is only an optional example and should not be construed as a limitation of the invention. Furthermore, the guidance indicator module also includes a power module, an input module, and a power interface. The display screen of the guidance indicator module is also used to display traffic flow information and provide corresponding guidance prompts. The power module is connected to and supplies power to other components of the guidance indicator module. Furthermore, the power module is also connected to the cone to power the cone's components, including the warning lights. In operation, external power input via the power interface reaches the power module and then powers all structural components of the traffic cone. The power module supplies power to the input module, microcontroller, and display screen. The input module is used by operators to input traffic cone information data. The input module is a button, and the traffic cone information data includes the total number of traffic cones, the current traffic cone identifier, or the current traffic cone number. In one embodiment, the microcontroller is connected to the input module via GPIO and communicates via I2C. In operation, the microcontroller receives input electrical signals or input information data from the input module (e.g., buttons, touchscreen, stylus), generates corresponding control signals, and transmits them to the display screen. The display screen receives the control signals and generates corresponding display states, such as displaying the shape and color of a clearly defined guidance sign corresponding to the control signal, as well as the background color on the screen. Preferably, the processor can be used to read input information data from the input module (e.g., buttons) of the microcontroller and run a control program based on a color control algorithm to control the color information display of the direction indicated on the display screen. The color information display includes the color to be displayed on the directional sign on the display screen and the background color to be displayed on the display screen.

[0044] The traffic cone guidance indication control method based on the color change control algorithm of the present invention will be specifically described below with reference to examples.

[0045] Figure 1 This is a flowchart illustrating an example of the traffic cone guidance indication control method based on a color change control algorithm according to the present invention.

[0046] like Figure 1 As shown, the traffic cone guidance indication control method includes the following steps.

[0047] Step S101: Initialize various parameters, including color vector information and initial display content of the display screen.

[0048] Step S102: Input the total number of traffic cones and input the current traffic cone identifier.

[0049] Step S103: Based on the input total number of traffic cones and the current traffic cone identifier, determine the color to be displayed for the current traffic cone according to the color change control algorithm. Specifically, if a change in the total number of traffic cones is detected, the color to be displayed for the current traffic cone is re-determined.

[0050] Specifically, the total number of traffic cones and the current cone identifier are re-entered, and the color to be displayed for the current traffic cone is determined based on the total number of traffic cones and the current cone identifier.

[0051] Figure 2 This is a schematic diagram of an example of a traffic cone using the traffic cone guidance indicator control method based on the color change control algorithm of the present invention. The following will be combined with... Figure 2 The invention is illustrated by an example of a traffic cone.

[0052] exist Figure 2 In the example, the traffic cone includes a directional indicator module for controlling the directional display on the screen. The directional indicator module includes a microprocessor, a display screen, an input module, and a power module. The microprocessor module runs a color change control algorithm to control the directional display on the screen. By applying the traffic cone directional indicator control method of this invention, the traffic cone can achieve intelligent directional display and intelligently control the directional display on the screen.

[0053] First, in step S101, various parameters are initialized, including color vector information and initial display content of the display screen.

[0054] Specifically, the microprocessor runs a color change control algorithm and initializes various parameters to initiate control of the guided display on the screen.

[0055] Optionally, the guide display may be a color display or a gradient color display.

[0056] Furthermore, the various parameters include color vector information, initial display content, such as GPIO port mode parameters, initial display content, gradient color vector parameters, etc.

[0057] It should be noted that the above is only an optional example and should not be construed as a limitation of the present invention.

[0058] Next, in step S102, the total number of traffic cones is entered, and the current traffic cone identifier is entered.

[0059] Specifically, an input module is used for input operations, such as a button.

[0060] In one embodiment, assuming the number of traffic cones is M, and each traffic cone is identified, the current traffic cone (sometimes referred to as the current cone in this document) is identified (the identification is, for example, a number) as N. The operator inputs the total number of traffic cones M (for example, M is 7) by pressing a key, and inputs the current traffic cone identification N (for example, 3).

[0061] Next, the microprocessor reads the current button state (i.e., input state) and performs the next data processing. This next data processing may include, for example, determining the color to be displayed on the current traffic cone and determining the color to be displayed on the directional signs on the display screen of the current traffic cone.

[0062] Furthermore, the current traffic cone identifier and the total number of traffic cones can be changed through the input status.

[0063] It should be noted that the above is only an optional example and should not be construed as a limitation of the present invention.

[0064] Next, in step S103, based on the input total number of traffic cones and the current traffic cone identifier, the color to be displayed for the current traffic cone is determined according to the color change control algorithm. When a change in the total number of traffic cones is detected, the color to be displayed for the current traffic cone is re-determined.

[0065] Specifically, based on the total number of traffic cones in the input traffic cone group, each traffic cone is identified, and a preset color vector corresponding to each traffic sign is configured.

[0066] For example, different traffic cones can be assigned a single indicator color, or a gradient color can be used for several traffic cones. Furthermore, the indicator color displayed on the screen of the directional indicator module is a gradient from red to green. Red indicates the starting point of construction, while green indicates the ending point.

[0067] Furthermore, based on the color change control algorithm, the color to be displayed on the current traffic cone is determined. More specifically, based on the gradient color mapping calculation method, the color to be displayed on the directional signs in the display screen on the current traffic cone is determined. Thus, the color to be displayed on the current traffic cone, and the colors to be displayed on all traffic cones, can be determined more intelligently and accurately, and the directional display of traffic cones can be controlled more intelligently.

[0068] Specifically, when the total number of traffic cones in the input traffic cone group is M, and the current traffic cone identifier is N, the color index of the current traffic cone is calculated using the following expression (1):

[0069] (1)

[0070] Among them, the The color vector is represented by x, where x is the color index; M represents the current traffic cone sign, where M is a positive integer; N represents the current traffic cone sign, where N is a positive integer; and K represents the index of the preset gradient color or color vector, where K is a positive integer.

[0071] It should be noted that the gradient from red to green is generated by a vector. It means that among them ( ( ) represents a preset gradient color. Then the... Traffic cones ( Display colors From the formula This leads to the expression (1) above.

[0072] For example, in a highway construction instance, if the input number of traffic cones is 7 and the current cone number is 3, the following can be calculated according to the above expression (1): middle The subscript value.

[0073] Next, the microprocessor reads the color information from the preset color vector based on the calculated color index of the current traffic cone, that is, it finds the color information with the index […]. The color is determined to determine the color to be displayed on the directional sign in the current traffic cone display screen.

[0074] Specifically, the color to be displayed by the determined directional sign is filled into the filling space of the directional sign to perform color display, wherein the color to be displayed is a gradient color.

[0075] Figure 3 This is a flowchart illustrating another example of the traffic cone guidance indication control method based on the color change control algorithm of the present invention. Figure 4 yes Figure 3 A more detailed flowchart.

[0076] See Figure 3 and Figure 4 The traffic cone guidance indication control method further includes a step S201 of detecting the input state, that is, from Figure 1 Step S103 is broken down into steps S201 and S103.

[0077] It should be noted that, due to Figure 3 Steps S101, S102, and S103 in the process are similar to... Figure 1 Steps S101, S102, and S103 are largely the same, therefore, their descriptions are omitted.

[0078] Specifically, in step S201, the input state is detected (i.e., the input parameters are detected or the key presses are detected). When a change in the total number of traffic cones is detected, the preset color vectors corresponding to each traffic sign are reconfigured according to the changed total number of traffic cones.

[0079] Furthermore, re-enter the total number of traffic cones after the change, and enter the current traffic cone identification number. Recalculate the color index of the current traffic cone to determine the color to be displayed on the screen before displaying it.

[0080] It should be noted that the above is only an optional example and should not be construed as a limitation of the present invention.

[0081] Figure 5 This is a schematic diagram of an example of a directional sign on a display screen in a traffic cone, which applies the traffic cone directional indication control method based on the color change control algorithm of the present invention.

[0082] like Figure 5 As shown, the guide sign is a sign strip with a bend. The guide sign is a sign strip with a filled space formed by translating a first line segment and a second line segment formed by a starting point, a bend point, and an end point along the horizontal direction of the display screen by a specified distance. The sign strip includes a first segment and a second segment that extend obliquely from the bend. The first segment and the second segment correspond to the first line segment (AB, DE) and the second line segment (BC, EF), respectively.

[0083] exist Figure 5 In this example, a 480*800 display screen is used. Points A, B, and C are selected as the starting points for the flow guidance markers, and two line segments (ABC and DEF) are drawn. The pixel coordinates of these three points are (180, 0), (0, 240), and (240, 480), respectively. Line segment ABC is then shifted 80 pixels to the right. Simultaneously, the closed area enclosed by A, B, C, D, E, and F is filled with color. Similarly, the colors of A', B', C', D', E', and F' can be filled.

[0084] The best display effect can be achieved by setting the directional signs as sign strips with bends.

[0085] It should be noted that the shape and size of the directional signs were determined through multiple experiments to find the optimal result. Furthermore, in Figure 5 In the example, there are two guide signs. However, this is not a limitation; in other embodiments, there may be three, four, or more guide signs.

[0086] Preferably, the traffic cone guidance indication control method further includes the background color to be displayed on the display screen on the current traffic cone.

[0087] Specifically, the system monitors light intensity and determines whether the monitored light intensity exceeds a set threshold to determine the background of the display screen on the current traffic cone. For example, a sensing device can be used to monitor light intensity.

[0088] In one embodiment, when the monitored light intensity is greater than the set threshold, the background color of the current traffic cone display screen is determined to be white.

[0089] In another embodiment, when the monitored light intensity is less than or equal to the set threshold, the background color of the display screen on the current traffic cone is determined to be black.

[0090] Furthermore, based on the determined colors to be displayed on the directional signs in the display screen, and based on the determined background color of the display screen, the color display on the current traffic cone is controlled. This achieves an intelligent control process.

[0091] Next, the background color of the display screens on the remaining traffic cones and the color of the directional signs displayed on the screens are determined sequentially to control the color display on all traffic cones. The display of all traffic cones after being controlled by the above method is as follows: Figure 6 As shown.

[0092] It should be noted that the above is only an optional example and should not be construed as a limitation of the present invention.

[0093] In an optional implementation, the method further includes determining the background color to be displayed on the current traffic cone display screen. Specifically, a photosensor monitors the light intensity and determines whether the monitored light intensity is greater than a set threshold to determine the background of the current traffic cone display screen. When the monitored light intensity is greater than the set threshold, the background color of the current traffic cone display screen is determined to be white; when the monitored light intensity is less than or equal to the set threshold, the background color of the current traffic cone display screen is determined to be black.

[0094] By monitoring light intensity with a photosensitive sensor, the background of the display screen on the traffic cone can be determined, which can accurately determine the background color of the display screen on the traffic cone at night, thus effectively avoiding the problem of poor display effect of traffic cones at night.

[0095] Furthermore, the color display of the current traffic cone's display screen is controlled based on the determined color of the directional signs to be displayed on the screen and the determined background color of the display screen.

[0096] Furthermore, the background color of the display screens on all traffic cones and the color of the directional signs to be displayed on the screens are determined, and the color display on the display screens on all traffic cones is controlled by a microcontroller to obtain the display effect of all traffic cones.

[0097] Compared with existing technologies, this invention initializes various parameters, inputs the total number of traffic cones and the current traffic cone identifier, and directly runs the device according to the color change control algorithm. This allows for a more intelligent and accurate determination of the color to be displayed for the current traffic cone and the colors to be displayed for all traffic cones. It also enables more intelligent control of the traffic cone's directional display, providing guidance for vehicle flow and pedestrians. This effectively avoids traffic congestion or even traffic accidents caused by the inability to provide guidance and direction for vehicles and pedestrians, thus ensuring traffic safety.

[0098] Furthermore, optimal display results can be achieved by setting the directional signs as sign strips with bends.

[0099] Furthermore, by calculating the color index of the current traffic cone through a color change control algorithm to determine the color of the directional sign to be displayed on the screen, and by monitoring the light intensity to determine whether the monitored light intensity is greater than a set threshold, the background of the display screen on the current traffic cone can be determined. This allows for more precise control of the color display on the current traffic cone, which not only further realizes intelligent control and display, but also effectively avoids the problem of poor display effect of traffic cones at night.

[0100] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that various general-purpose devices can also implement the present invention. The above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
