Detailed Implementation
[0041] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.
[0042] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.
[0043] This disclosure provides a traffic light system. See also: Figure 3The traffic light system includes a traffic light device 1, a manually driven vehicle 2, an unmanned vehicle 3, and a cloud control module 4. The manually driven vehicle 2 and the unmanned vehicle 3 can be mining dump trucks or other types of vehicles. The manually driven vehicle 2 is driven by a driver, and the unmanned vehicle 3 is controlled by an unmanned driving system. The unmanned vehicle 3 may include a vehicle body and a second communication unit 31. The second communication unit 31 is configured to send location information, specifically the real-time location of the unmanned vehicle 3, to the cloud control module 4 when the unmanned vehicle 3 enters the intersection area.
[0044] The cloud control module 4 is configured to send a switching signal to the traffic light device 1, and is also configured to not send a switching signal to the traffic light device 1 in response to location information when the driverless vehicle 3 is able to pass through the intersection.
[0045] Traffic light device 1 can be installed at an intersection and is used to receive switching signals to change the light color. Manually driven vehicles 2 can proceed under one light color, while autonomous vehicles 3 can proceed under another light color, indicating that manually driven vehicles 2 and autonomous vehicles 3 can proceed in batches. Traffic light device 1 has at least two light colors. For example, traffic light device 1 can have two light colors. Under one light color, autonomous vehicles 3 can proceed, and manually driven vehicles 2 must stop and wait; under the other light color, autonomous vehicles 3 stop and wait, and manually driven vehicles 2 can proceed. As another example, traffic light device 1 can have three light colors. Under the first and second light colors, autonomous vehicles 3 can proceed, and manually driven vehicles 2 must stop and wait. The second light color can warn the driver of manually driven vehicles 2 that the light color needs to be changed; under the third light color, autonomous vehicles 3 stop and wait, and manually driven vehicles 2 can proceed.
[0046] Thus, by sending a switching signal to the traffic light device 1 via the cloud control module 4, the traffic light device 1 can switch light colors, allowing manually driven vehicles 2 to pass under one light color and unmanned vehicles 3 to pass under another. This instructs manually driven vehicles 2 and unmanned vehicles 3 to pass in batches, reducing the possibility of mutual interference when they cross the intersection, and facilitating their safe and efficient operation. Furthermore, when unmanned vehicles 3 are able to pass, they send location information to the cloud control module 4, which then refrains from sending a switching signal to the traffic light device 1, ensuring that the traffic light device 1 does not switch light colors. This allows unmanned vehicles 3 to safely pass through the intersection, improving the flexibility of the traffic light system and making it suitable for complex and variable operating environments and conditions.
[0047] In one embodiment of this disclosure, see Figure 3 The driverless vehicle 3 also includes a sensing module 32, which is used to sense the position of the manually driven vehicle 2. For example, the manually driven vehicle 2 may have radar, which can send electrical signals to the sensing module 32. The sensing module 32 can determine the position of the manually driven vehicle 2 based on the electrical signals and maintain a safe distance from the manually driven vehicle 2 to improve driving safety and system reliability.
[0048] In one embodiment of this disclosure, the cloud control module 4 can be configured to switch light colors according to a certain frequency and sequence. The frequency of light color switching can be changed according to location information to improve traffic convenience.
[0049] In one embodiment of this disclosure, see Figure 1 and Figure 2 The traffic light device 1 includes a base 11, a traffic light 12, and a control assembly 13. The base 11 includes a seat body 111 and a pole 112. The seat body 111 has a receiving cavity, and the pole 112 is disposed on the seat body 111 and fixedly connected to the seat body 111. The pole 112 extends in a direction perpendicular to the seat body 111.
[0050] Traffic light 12 is located at the end of pole 112 away from base 111, and has at least a first light and a second light. The first light and the second light have different colors. The first light is used for unmanned vehicles 3 to pass, and the second light is used for manually driven vehicles 2 to pass.
[0051] Control component 13 is configured to control traffic light 12 to switch between at least the first light and the second light in response to a switching signal.
[0052] Thus, when traffic light 12 is the first light, after receiving the switching signal, control component 13 will control traffic light 12 to switch to the second light to indicate that the manually driven vehicle 2 can pass. When traffic light 12 is the second light, after receiving the switching signal, control component 13 will control traffic light 12 to switch to the first light to indicate that the unmanned vehicle 3 can pass.
[0053] In one embodiment of this disclosure, the first light can be red and the second light can be green. Thus, since the second light is green, it offers better adaptability to manually driven vehicle 2. In other embodiments of this disclosure, the first light can be yellow and the second light can be green. In still other embodiments of this disclosure, the first light can also be yellow and the second light can be green.
[0054] In one embodiment of this disclosure, see Figure 1 and Figure 2 The seat 111 may include a base plate, side plates, and a top plate. The side plates and the base plate form a receiving cavity, and the side of the side plate away from the base plate is connected to the top plate, so that the side plates, base plate, and top plate are connected as a single unit. The shape of the seat 111 may be prism-shaped, cylindrical, hemispherical, pyramidal, or other spatial geometric shapes. In other embodiments of this disclosure, the base plate, side plates, and top plate may also be integrally connected, making the seat 111 a single-piece structure.
[0055] In one embodiment of this disclosure, the side plate may include four baffles, which are connected end to end to form a cuboid structure. The side wall of the base plate may be welded or integrally connected with multiple protruding rings to facilitate the movement of the base 111 by hand by applying force to the protruding rings.
[0056] In one embodiment of this disclosure, a mounting bracket may be provided on the base plate. When installing the traffic light device 1, the stability of the base 111 can be increased by applying counterweights to the mounting bracket. Alternatively, bolts can be inserted through the mounting bracket and driven into the ground to improve the structural stability of the traffic light device 1.
[0057] In one embodiment of this disclosure, the bottom of the base plate may be provided with multiple rollers, which can be stored in the base plate, and the base plate has a storage cavity for storing the rollers. In this way, on the one hand, it is convenient for the staff to move the traffic light device 1 using the rollers; on the other hand, when fixing the traffic light device 1, the rollers can be stored in the storage cavity to improve the stability of the traffic light device 1.
[0058] In one embodiment of this disclosure, the bottom plate and the top plate may each be provided with a snap-fit part on the same side, and the upright 112 can pass through the two snap-fit parts. The snap-fit parts can be welded, glued or snapped to the upright 112 to improve the connection stability of the upright 112.
[0059] Of course, the base 111 may also include a cubic frame, with the bottom plate, side plates and top plate all mounted on the cubic frame.
[0060] In one embodiment of this disclosure, see Figures 1-3 The control component 13 includes an antenna 131, a first communication unit 132, and a control unit 133.
[0061] The antenna 131 is located at the end of the pole 112 away from the base 111 and is configured to receive switching signals and send switching signals to the first communication unit 132. The antenna 131 can be fixedly connected to the pole 112 by means of bolt connection, welding, bonding or other methods.
[0062] The first communication unit 132 is disposed in the receiving cavity and is configured to send a switching command to the control unit 133 in response to a switching signal; the first communication unit 132 can be connected to the receiving cavity by screws.
[0063] The control unit 133 is disposed in the receiving cavity and configured to control the traffic light 12 to switch between at least the first light and the second light in response to a switching command.
[0064] Thus, when the color of the traffic light 12 needs to be changed, the antenna 131 can receive the switching signal sent by the cloud control module 4, and then send the switching signal to the first communication unit 132 for processing. After processing the switching signal, the first communication unit 132 sends a switching command to the control unit 133. After receiving the switching command, the control unit 133 executes the switching action to facilitate the switching of the color of the traffic light 12, so that the traffic light 12 can update the light in real time, which is conducive to the timely and accurate transmission of the switching signal.
[0065] In one embodiment of this disclosure, the traffic light 12 further includes a third light and a fourth light. The third light is used for the passage of the driverless vehicle 3, and the fourth light is used for the passage of the manually driven vehicle 2; the first light and the third light have the same color, the second light and the fourth light have the same color, the first light and the second light are constantly lit, and the third light and the fourth light are flashing lights.
[0066] The control unit 133 is also configured to control the traffic light 12 to switch to one of the following four lights in response to a switching command: a first light, a second light, a third light, and a fourth light. The traffic light 12 switches in the order of first light, third light, second light, and fourth light. In one example, when the traffic light 12 is in the first light position, the control unit 133, upon receiving a switching command, controls the traffic light 12 to switch to the third light. In another example, when the traffic light 12 is in the third light position, the control unit 133, upon receiving a switching command, controls the traffic light 12 to switch to the second light. In other examples, when the traffic light 12 is in the second light position, the control unit 133, upon receiving a switching command, controls the traffic light 12 to switch to the fourth light. In still other examples, when the traffic light 12 is in the fourth light position, the control unit 133, upon receiving a switching command, controls the traffic light 12 to switch back to the first light.
[0067] In this way, the third light serves as a continuation of the first light, and the fourth light serves as a continuation of the second light, to provide a warning to the driver of the manually driven vehicle 2, so as to facilitate the safe and efficient transportation operation of the manually driven vehicle 2.
[0068] In one embodiment of this disclosure, when the traffic light 12 is in the third light position, the cloud control module 4, after receiving the location information, does not send a switching signal to the control component 13 until the unmanned vehicle 3 that sent the location information passes through the intersection. In other words, when the traffic light 12 is in the third light position, after the unmanned vehicle 3 enters the intersection area, the traffic light 12 does not switch the light color, so that the unmanned vehicle 3 can operate safely and efficiently.
[0069] It should be noted that in the embodiments disclosed herein, the intersection range refers to the area at a certain distance from the intersection. When the driverless vehicle 3 enters the intersection range, it will send location information to the cloud control module 4.
[0070] In one embodiment of this disclosure, the first and third lights are red, and the second and fourth lights are green. In other words, the first light is a constant red light, and the third light is a flashing red light; the second light is a constant green light, and the fourth light is a flashing green light. When the red light is flashing, if there is an unmanned vehicle 3 within the intersection area, the traffic light 12 will not turn green until the unmanned vehicle 3 passes through the intersection.
[0071] In one embodiment of this disclosure, see Figure 1 and Figure 3 The traffic light device 1 also includes a camera assembly 14, which may include a camera. The camera can be installed at the end of the pole 112 away from the base 111. The camera can be fixedly connected to the pole 112 by means of bolts, snap-fit, etc., and the traffic light 12 is located between the camera and the base 111. The camera is configured to send image data to the first communication unit 132; the first communication unit 132 is configured to receive the image data and send the image data to the cloud control module 4. The cloud control module 4 can process the image data and send it to the display panel of the monitoring center for display. Staff can remotely view the situation around the traffic light 12 through the monitoring center, monitor the traffic conditions in the mining area in real time, and make manual interventions when necessary; for example, adjusting the status of the traffic light 12 or handling emergencies.
[0072] In one embodiment of this disclosure, see Figure 1 and Figure 2The traffic light device 1 may also include a fault detection component 15. The fault detection component 15 can be housed within a receiving cavity and is configured to detect whether the traffic light 12 and control component 13 are malfunctioning. When either the traffic light 12 or the control component 13 malfunctions, the fault detection component 15 issues an alarm signal. For example, the fault detection component 15 can detect whether the illumination status, light color, and light switching sequence of the traffic light 12 are normal. The fault detection component 15 can also detect whether communication between the control component 13 and the cloud control module 4 is interrupted. The fault detection component 15 can be electrically connected to the control component 13, the traffic light 12, and the cloud control module 4 respectively to achieve fault detection. When the fault detection component 15 detects a fault in the traffic light device 1, it will initiate an internal self-test program to accurately detect the fault point, and will also switch to a safety mode and issue an alarm signal, such as an alarm sound. Thus, by using the fault detection component 15 to detect whether the traffic light device 1 is malfunctioning, manual intervention is possible when the traffic light device 1 malfunctions, which helps improve traffic safety and transportation efficiency.
[0073] In one embodiment of this disclosure, see Figure 1 and Figure 2 The traffic light device 1 also includes a power supply assembly 16, which can be a battery, a generator, or other power supply equipment. The power supply assembly 16 is housed within a receiving cavity and is electrically connected to the traffic light 12, control assembly 13, camera assembly 14, and fault detection assembly 15 to supply power to these components. For example, the power supply assembly 16 can be a 12V battery, with a length of 415mm, a width of 335mm, and a height of 180mm.
[0074] The working principle of the traffic light system will be explained below.
[0075] When traffic light 12 is in the first light position, driverless vehicle 3 can proceed, while manually driven vehicle 2 must stop and wait.
[0076] When traffic light 12 needs to switch from the first light to the third light, the cloud control module 4 sends a switching signal to the first communication unit 132. After receiving the switching signal through antenna 131, the first communication unit 132 sends a switching command to the control unit 133, which then controls the traffic light 12 to switch from the first light to the third light. At this time, the driverless vehicle 3 can still pass. Under the third light, after the driverless vehicle 3 enters the intersection area, the second communication unit 31 sends location information to the cloud control module 4. The cloud control module 4 does not send a switching signal to the first communication unit 132 based on the location information until the driverless vehicle 3 that sent the location information passes through the intersection. Then, the cloud control module 4 sends a switching signal to the first communication unit 132, causing the traffic light 12 to switch to the second light.
[0077] Under the second light, manually driven vehicle 2 can pass, while driverless vehicle 3 needs to stop and wait.
[0078] When traffic light 12 needs to switch from the second light to the fourth light, the cloud control module 4 sends a switching signal to the first communication unit 132. After receiving the switching signal through antenna 131, the first communication unit 132 sends a switching command to the control unit 133. The control unit 133 then controls the traffic light 12 to switch from the second light to the fourth light. At this time, the manually driven vehicle 2 can still pass.
[0079] When traffic light 12 needs to switch from the fourth light to the first light, the cloud control module 4 sends a switching signal to the first communication unit 132. After receiving the switching signal through antenna 131, the first communication unit 132 sends a switching command to the control unit 133. The control unit 133 then controls the traffic light 12 to switch from the fourth light to the first light. At this time, the driverless vehicle 3 can proceed, while the manually driven vehicle 2 needs to stop and wait.
