Description

Technical Field

[0001] The invention relates to the technical field of traffic signal controllers, and in particular to a centralized coordinated traffic signal controller. Background Art

[0002] Traffic signal controller is a device that can change the order of road traffic signals, adjust the timing and control the operation of road traffic lights. Traffic signal controller is the core component of urban traffic signal control system. It is the bottom-level execution unit located at the intersection in the traffic signal control system. Its core function is to realize intersection traffic signal control, and it also has functions such as traffic information collection, communication, and intersection monitoring.

[0003] The patent document with patent announcement number: CN116665467B discloses an intelligent traffic signal controller. This solution is to solve the problem of how the traffic signal controller itself can maintain a long working life and measure vehicle flow during peak hours when the main roads in the city are often in an oversaturated operating state; however, this solution only considers how the machine copes with long-term work, but does not consider the long-term work of traffic police and other staff who perform traffic coordination tasks.

[0004] The patent document with patent announcement number: CN115500056B discloses an outdoor traffic signal controller. This solution improves the problem that the traffic signal controller needs effective heat dissipation during long-term work, but it also does not take into account the problem of heatstroke prevention and cooling for traffic police and other personnel who perform traffic coordination tasks during long hours of work.

[0005] Since the current traffic signal controllers are not able to automatically adjust the order and duration of the lights when there is traffic congestion by using big data or intelligent algorithms, the on-duty traffic police often need to control the order and duration of the lights according to the on-site situation so that the more congested road can go first. After the road congestion is alleviated to a certain extent, the traffic police and other staff can often stop manual intervention. Traffic signal controllers are often installed near intersections and are generally not covered. When encountering severe weather such as scorching heat or thunderstorms, on-duty traffic police need to stand at the traffic signal controller for a long time to work, which not only places high demands on the physical strength and endurance of on-duty traffic police, but also makes it easy for on-duty traffic police to become dehydrated or unresponsive due to being in this working environment for a long time, which may lead to more serious physical problems and road traffic problems. Summary of the invention

[0006] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a centralized coordinated traffic signal controller, which solves the problems of health and traffic control caused by the external environment when on-duty traffic police and other staff operate the traffic signal controller outdoors for a long time.

DETAILED DESCRIPTION

[0044] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 1 As shown, a centralized coordinated traffic signal controller includes a cabinet 1 and a cabinet door 3. A monitoring module 4 and a control module 5 are installed inside the cabinet 1. The monitoring module 4 is used for users to monitor the traffic flow gathering on the road near the intersection; the control module 5 is used to control the lighting order and duration of the signal lights at the intersection;

[0046] The cabinet door 3 uses the cabinet body 1 as the assembly basis, and a linear drive mechanism, an installation bin 7 and a heat dissipation module 8 are arranged inside the cabinet door 3; the heat dissipation module 8 is rotatably accommodated inside the installation bin 7, and the linear drive mechanism is used to drive the installation bin 7 to reciprocate linearly; the heat dissipation module 8 includes a heat dissipation fan 81, and the heat dissipation fan 81 has two oppositely arranged surfaces, one of which is an air suction surface for sucking in external natural wind, and the other surface is a blowing surface for blowing out natural wind to the outside.

[0047] According to the technical scheme in the previous paragraph, this technical scheme not only optimizes the heat dissipation problem of the traffic signal controller when it is used outdoors for a long time, but also takes into account some problems faced by users who control the traffic signal controller on site when working outdoors for a long time. In actual use, when the cabinet door 3 is in a closed state, the linear drive mechanism is started to drive the installation chamber 7 and the heat dissipation module 8 to move back and forth, and the monitoring module 4 and the control module 5 in the cabinet 1 are continuously cooled and cooled by the flow of natural wind. When the cabinet door 3 is in an open and closed state, the user manually intervenes in the control, and the heat dissipation module 8 can cooperate with the installation chamber 7 to rotate into a seat for the user to sit on. In addition, this scheme effectively utilizes the different functions of different surfaces of the heat dissipation fan 81 in the heat dissipation module 8. When the heat dissipation module 8 mainly dissipates heat and cools the equipment in the cabinet 1, the blowing surface of the heat dissipation fan 81 is always facing the inside of the cabinet 1, blowing natural wind to the equipment, and when the heat dissipation module 8 acts as a seat, the suction surface of the heat dissipation fan 81 faces upward, and the heat on the user's skin surface and in the clothes is sucked away by suction, so as to achieve the purpose of cooling down the user.

[0048] As an example, a base 2 is installed at the bottom of the cabinet 1, the bottom of the base 2 is hollow, and a plurality of air outlets are provided on the top of the base 2. On the one hand, the cabinet 1 can be raised to prevent water from entering when there is water accumulation in thunderstorms. On the other hand, more air flow channels are provided for the cabinet 1, which is beneficial to the heat dissipation of the monitoring module 4 and the control module 5.

[0049] As an example, Figure 4 As shown, a mounting plate 51 is provided inside the cabinet 1, and the mounting plate 51 is in a V-shaped structure. The side with a protruding angle formed in the middle position of the mounting plate 51 is defined as the windward side. The control module 5 is installed on the windward side of the mounting plate 51, and heat dissipation holes 11 are provided on both sides of the cabinet 1; when the blowing side of the cooling fan 81 faces the windward side of the mounting plate 51, the V-shaped design of the mounting plate 51 will allow the natural wind to flow through the control module 5 and then be quickly discharged through the heat dissipation holes 11 on both sides of the cabinet 1. This is because the V-shaped structure can increase the flow area and flow rate of the wind, so that the air can more effectively take away heat when flowing between the V-shaped surfaces, thereby enhancing the heat dissipation effect.

[0050] As an example, three metal hinges are arranged between the cabinet body 1 and the cabinet door 3 from top to bottom to ensure the load-bearing capacity of the cabinet door 3 .

[0051] As an example, Figure 2 , Figure 3 As shown, a limit assembly 6 is arranged between the cabinet body 1 and the cabinet door 3, and the limit assembly 6 includes a limit rod 63 and two limit blocks 1 61 respectively installed in the cabinet body 1 and a limit block 2 62 at the cabinet door 3, and the limit block 1 61 and the limit block 2 62 are kept parallel; wherein, the position between the two limit blocks 1 61 is fixed, and the position of the limit block 2 62 at the inner wall of the cabinet door 3 can be adjusted by screw installation, and the spacing between the two limit blocks 1 61 matches the length of the limit rod 63. When the cabinet door 3 is in a closed state, the two ends of the limit rod 63 are respectively engaged with the two limit blocks 1 61. At this time, the limit rod 63 is retracted into the cabinet body 1 and will not hinder the opening and closing of the cabinet door 3; when the cabinet door 3 is in an open and closed state, the two ends of the limit rod 63 are respectively engaged with the limit block 1 61 and the limit block 2 62, thereby limiting the opening and closing angle of the cabinet door 3, avoiding the cabinet door 3 from continuing to rotate when the user sits on the heat dissipation module 8, causing inconvenience in use.

[0052] As an example, Figure 5 , Figure 6 As shown, a rectangular reinforcement frame 31 is installed on the inner wall of the cabinet door 3 to improve the strength of the cabinet door 3; the linear drive mechanism includes a screw rod 32, a motor 33 and a fixed bearing 34 perpendicular to the horizontal ground, the motor 33 is installed on the upper end of the inner wall of the cabinet door 3, and the fixed bearing 34 is installed on the lower end of the reinforcement frame 31. One end of the screw rod 32 is fixedly connected to the output end of the motor 33, and the other end of the screw rod 32 is rotatably connected to the fixed bearing 34; and the mounting bin 7 is threadedly connected to the screw rod 32 through a mounting seat 75 arranged on the back side thereof.

[0053] According to the above technical solution, when the motor 33 is started, the screw rod 32 begins to rotate, and the mounting bin 7 and the heat dissipation module 8 will move in the vertical direction under the action of the threads of the screw rod 32 and the mounting seat 75, thereby changing the height position of the heat dissipation module 8, and effectively dissipating heat and cooling the monitoring module 4 and the control module 5 placed from top to bottom in the cabinet 1.

[0054] It should be noted that when the equipment in the cabinet 1 is cooled down by heat, the heat dissipation module 8 is stored in the installation compartment 7 , and the blowing surface of the heat dissipation fan 81 is always facing the equipment in the cabinet 1 .

[0055] The above technical solution is further refined, such as Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, there are two mounting seats 75, which are respectively mounted on the upper and lower ends of the back of the mounting bin 7; a threaded hole is formed through the middle of the mounting seat 75, which is threadedly connected to the screw rod 32, and notches are formed on both sides of the mounting seat 75, and rubber rollers 76 are rollingly connected to the notches. When the mounting bin 7 reciprocates along the length direction of the screw rod 32, the rubber rollers 76 are rollingly connected to the cabinet door 3, and the rolling direction of the rubber rollers 76 is the same as the moving direction of the mounting bin 7. The two mounting seats 75 can increase the stability of the mounting bin 7 during movement, and the rubber rollers 76 located on both sides of the mounting seat 75 can improve the problem of large friction during movement caused by the direct contact between the mounting bin 7 and the cabinet door 3, and can also make the mounting bin 7 more stable during movement.

[0056] The above technical solution is further refined, such as Fig.10 As shown, a mounting groove 71 is provided on the front of the mounting bin 7, and a cooling fan 81 is rotatably connected to the lower end of the mounting groove 71 through a rotating shaft. Telescopic rods 73 are provided on both sides of the cooling fan 81. The telescopic rods 73 adopt a damping design, one end of the telescopic rod 73 is rotatably connected to the mounting bin 7, and the other end of the telescopic rod 73 is rotatably connected to the cooling fan 81; when the telescopic rod 73 is in a fully retracted state, the telescopic rod 73 and the cooling fan 81 are completely retracted into the mounting groove 71, and the overall appearance is beautiful without any foreign matter sticking out. When the cooling module 8 is rotated and the telescopic rod 73 reaches its maximum extension length, the rotation opening and closing angle between the cooling module 8 and the mounting bin 7 is also the largest.

[0057] It should be noted that the heat dissipation module 8 remains parallel to the horizontal ground after rotation. At this time, the heat dissipation module 8 is relatively comfortable to sit on. If the rotation angle between the heat dissipation module 8 and the installation compartment 7 is too large, it may cause the user to slide down after sitting on the heat dissipation module 8.

[0058] It should be noted that before the user sits on the heat dissipation module 8, the motor 33 can be started to drive the screw 32 to rotate, so that the installation bin 7 and the heat dissipation module 8 can be adjusted to a suitable height for the user to sit on, which is suitable for users of different heights and more user-friendly.

[0059] As an example, in this solution, the installation chamber 7 and the heat dissipation module 8 are both square structures.

[0060] The above technical solution is further refined, and the air suction surface and the air blowing surface of the cooling fan 81 are both covered with a mesh plate 82. The mesh plate 82 can prevent foreign matter from entering the cooling fan 81 on the one hand, and on the other hand, the mesh plate 82 can prevent the user's clothes from being rolled into the cooling fan 81 when the user sits on the cooling module 8.

[0061] For further refinement of the above technical solution, refer to Figure 7, Figure 8 , Fig.10 As shown, an air inlet 72 connected to the mounting groove 71 is formed on the side of the mounting bin 7, and the main function of the air inlet 72 is: when the heat dissipation module 8 is received in the mounting bin 7, since the two fit tightly and the heat dissipation fan 81 needs to inhale the external natural wind during the rotation, the opening of the air inlet 72 can make the air suction surface of the heat dissipation fan 81 inhale the natural wind from the air inlets 72 on both sides of the mounting bin 7, thereby realizing the normal rotation of the heat dissipation fan 81, and the opening of the air inlet 72 is also beneficial to the heat dissipation and cooling of the heat dissipation module 8 itself.

[0062] To further refine the above technical solution, a buckle groove 74 is formed on the front side of the installation compartment 7 at an edge position corresponding to the installation groove 71 , and the buckle groove 74 can help the user to buckle the heat dissipation module 8 to rotate out of the installation groove 71 .

[0063] like Figure 1 , Fig.11 , Fig.12 As shown, a top cover assembly 9 is provided on the top of the cabinet 1 , and the top cover assembly 9 includes a top seat 91 , a main board 92 and a secondary board 93 .

[0064] A top seat 91 is installed on the top of the cabinet body 1, and the top seat 91 has a trapezoidal structure, wherein the higher end of the top seat 91 faces the cabinet door 3, and the lower end of the top seat 91 faces away from the cabinet door 3; a main board 92 is slidably connected above the top seat 91, and the sliding direction of the main board 92 faces the cabinet door 3; a slave board 93 is slidably connected to the left and right sides of the top of the main board 92.

[0065] According to the above technical solution, when it rains, the inclined design of the top seat 91 will cause the raindrops accumulated on the top seat 91 to drip in the direction away from the cabinet door 3, avoiding the raindrops from directly separating from the cabinet door 3, thereby reducing the probability of water entering the cabinet body 1; in addition, when encountering thunderstorms, the main board 92 can be pulled toward the cabinet door 3 to slide, so that the main board 92 extends toward the cabinet door 3, and the secondary boards 93 on both sides are pulled left and right to cover the area of ​​the cabinet door 3, such as Fig.11 As shown, even if a user controls the equipment in the cabinet 1 during a thunderstorm, the user's body will not get wet on a large scale; and the cabinet can also provide a sunshade function in hot summer weather.

[0066] The above technical solution is further refined. A slide groove 94 is provided on the top surface of the top seat 91, and a slide rail 95 matching the slide groove 94 is provided on the bottom of the main board 92, and the slide rail 95 is slidably limitedly connected to the slide groove 94; movable grooves 97 with a thickness matching the slave plate 93 are provided on the left and right sides of the top of the main board 92, and guide rods 98 are provided on the main board 92 in the direction of the slave plate 93, and the slave plates 93 on the left and right sides are slidably connected to the guide rods 98; when the slave plate 93 is not unfolded, the top surface of the main board 92 and the top surface of the slave plate 93 remain parallel.

[0067] As an example, Fig.13 , Fig.14 As shown, the main board 92 is tilted downward at one end toward the cabinet door 3 to form a baffle plate 1 96, and the baffle plate 2 99 is tilted downward from the end of the board 93 close to the outside to form a baffle plate 1; on the one hand, the baffle plates 1 96 and 99 can guide the flow of raindrops, so that the raindrops are as far away from the cabinet body 1 as possible when dripping from the main board 92 and the top surface of the board 93; on the other hand, the two can also act as handles when manually pulling out the main board 92 and the board 93, so that the user can push and pull, and it is convenient to use.

[0068] In this solution, the top of the cabinet 1 is also provided with an expandable top cover assembly 9 to protect the cabinet 1 and the user from wind and rain, improve the user's working environment, and improve the accuracy and timeliness of the user's traffic control during long-term work.
