Description

Technical Field

[0001] The present invention relates to the technical field of a control system for warning of bad weather on highways, and specifically to a control system for warning of bad weather on highways. Background Technique

[0002] Highways, abbreviated as expressways, refer to roads specifically for high-speed vehicle travel. With the improvement of people's living standards, the number of vehicles on expressways is gradually increasing. Traffic safety is a key consideration, and bad weather is one of the factors affecting traffic safety. For example, the "patchy fog" is such bad weather. The "patchy fog" is also known as lumpy fog. In essence, it is also fog. Affected by the local microclimate environment, within a local range of dozens to hundreds of meters in the thick fog, there appears a denser fog with lower visibility. The visibility outside the patchy fog is good, while it is hazy inside the patchy fog. The patchy fog is regionally strong and difficult to predict and forecast.

[0003] Currently, in order to warn of patchy fog and improve traffic safety, a control system for warning of patchy fog is often adopted, and the camera is the component directly facing the patchy fog in the control system.

[0004] However, during the use of the control system for patchy fog warning, the working angle of the camera cannot be adjusted, so that the monitoring angle of the camera during operation cannot be adjusted, which is not conducive to the long-term use of the device. Moreover, since the camera is used outdoors for a long time and has no protection measures, it is easily damaged by the impact of falling objects on the top, affecting its use. For this reason, we propose a control system for real-time warning of patchy fog on highways to solve the problems raised in the above background technique. Summary of the Invention

[0005] In order to solve the problems raised in the above background technique, the present invention provides a control system for warning of bad weather on highways.

[0006] The control system for warning of bad weather on highways provided by the present invention adopts the following technical solutions:

[0007] A control system for warning of bad weather on highways includes a mounting plate for mounting on the gantry on the highway;

[0008] A protection component, which includes a bearing plate, elastic members, and a folding member. There are two elastic members, both of which are in an inverted U-shaped structure and are both arranged on the bearing plate. The two elastic members are connected by the folding member for protecting the top of the camera;

[0009] A rotating assembly, which includes a rotating shaft, a driving mechanism, and two rotating members. The rotating shaft is rotatably arranged on a mounting plate.

There are two inserting parts, which are respectively arranged on the same side of the inner sides of the two elastic members, both above the rotating part and the clamping part. There are two inserting mating parts, which are respectively arranged on one side of the vertical plate and one side of the bearing plate;

[0016] A sliding part, a main sliding mating part, and a secondary sliding mating part. The sliding part is slidably arranged on an elastic member corresponding to the rotating part. The main sliding mating part is arranged at one end of the top of the bearing plate close to the rotating mating part, and the secondary sliding mating part is arranged on the side of the bearing plate adjacent to the rotating mating part;

[0017] The elastic member has a horizontal and a vertical state. When the elastic member is in the vertical state, the folding member extends to shield and protect the top of the camera. The rotating part cooperates with the rotating mating part, the clamping part cooperates with the main clamping mating part, and the sliding part and the main sliding mating part cooperate to limit the rotation of the elastic member and do not store the folding member. When the elastic member is in the horizontal state, the folding member contracts. The rotating part cooperates with the main clamping mating part, the clamping part cooperates with the secondary clamping mating part, the two inserting parts respectively cooperate with the two inserting mating parts, and the sliding part cooperates with the secondary sliding mating part to store the folding member.

[0018] In some embodiments, the folding member includes a folding cloth for connecting the two elastic members.

[0023] In some embodiments, the vertical section of the elastic member can be made of an elastic steel sheet, and the horizontal section can be made of a rigid steel sheet.

[0024] In some embodiments, the driving mechanism includes a motor and a reducer disposed on the mounting plate, and the motor is drivingly connected to the reducer.

[0025] Both rotating members are gears. One gear is sleeved on the rotating shaft, and the other gear is connected to the output shaft of the reducer, and the two gears are meshingly connected.

[0026] In some embodiments, it further includes a telescopic assembly, and the telescopic assembly includes

[0027] a fixing plate, which is fixed at one end of the outer wall of the rotating shaft;

[0028] a main telescopic member, which is disposed on the fixing plate and is used to adjust the use height of the camera;

Detailed implementation manners

[0043] The following will Figure 1-8 describe the present invention in further detail with reference to the accompanying drawings.

[0044] An embodiment of the present invention discloses a control system for a highway that can give early warnings of bad weather.

[0045] Embodiment 1

[0046] Referring to Figure 1-8 , a control system for a highway that can give early warnings of bad weather includes a mounting plate 1, which is used to be mounted on the gantry on the highway;

[0047] A protection assembly 4, which includes a bearing plate 43, elastic members 41 and a folding member 42. There are two elastic members 41, and both are in an inverted U-shaped structure and are both arranged on the bearing plate 43. The two elastic members 41 are connected by the folding member 42 for protecting the top of the camera;

[0048] A rotating assembly 2, which includes a rotating shaft 24, a driving mechanism 22 and two rotating members 23. The rotating shaft 24 is rotatably arranged on the mounting plate 1. The driving mechanism 22 is connected to one rotating member 23 to drive the rotating member 23 to rotate, and the other rotating member 23 is arranged on the rotating shaft 24 for driving the bearing plate 43 to rotate.

[0049] The rotating assembly 2 further includes an outer box 21, which is installed on the mounting plate 1 for shielding the driving mechanism 22 and the two rotating members 23. One end of the rotating shaft 24 penetrates the outer box 21, and the penetrating part is rotatably connected through a bearing.

[0050] The vertical section of the elastic member 41 can be made of elastic steel sheets, and the horizontal section can be made of rigid steel sheets.

[0051] The driving mechanism 22 includes a motor and a speed reducer arranged on the mounting plate 1, and the motor is drivingly connected to the speed reducer;

[0052] Both of the two rotating members 23 are gears. One gear is sleeved on the rotating shaft 24, and the other gear is connected to the output shaft of the speed reducer, and the two gears are meshingly connected.

[0053] The camera can be first installed on the mounting plate 1. The mounting plate 1 is preset with an opening hole for installing the camera. When the angle of the camera needs to be adjusted, the driving mechanism 22 drives one rotating member 23 to rotate, drives the rotating shaft 24 to rotate through the other rotating member 23, thereby driving the bearing plate 43 to rotate, so as to adjust the camera angle and adjust the monitoring view, which is convenient for long-term use. The elastic member 41 can be installed on the bearing plate 43, and the folding member 42 is in an extended state to protect the top of the camera. When an object falls, the folding member 42 blocks the falling object. The horizontal section of the elastic member 41 supports the folding member 42, and the vertical section can absorb the elastic force and buffer the acting force, bounce the falling object, thereby protecting the top of the camera and preventing damage caused by the impact of the falling object.

[0054] It should be further understood that the driving mechanism 22 adopts the method of a motor and a speed reducer, which can make the camera rotate slowly, making the monitoring situation clearer and more stable. The rotating member 23 uses gears for transmission, and the transmission stability of the motor and the speed reducer is better, so that the rotating shaft 24 can rotate more stably.

[0055] Embodiment 2

[0056] Refer to Figure 1-8 , the protection component 4 further includes an adjusting mechanism 44. There are two adjusting mechanisms 44, which are located on both sides of the bearing plate 43, and a region for installing the camera is formed between the two adjusting mechanisms 44. The adjusting mechanism 44 includes

[0057] A vertical plate 442, which is installed on one side of the top of the bearing plate 43;

[0058] [[ID=

[23] ]]A rotating part 441 and a rotating matching part 448. The rotating part 441 is arranged at the bottom of the inner side of one elastic member 41, and the rotating matching part 448 is arranged at one end of one side of the bearing plate 43 for the rotation of one elastic member 41;

[0059] A clamping part 445, a main clamping matching part 447 and a secondary clamping matching part 443. The clamping part 445 is arranged at the bottom of the inner side of the other elastic member 41, the main clamping matching part 447 is arranged at one end of the bearing plate 43 far from the rotating part 441, and the secondary clamping matching part 443 is arranged on the vertical plate 442, and the position corresponds to that of the main clamping matching part 447;

[0060] The insertion part 446 and the insertion mating part 444. There are two insertion parts 446, which are respectively arranged on the same side inside the two elastic members 41, and are both located above the rotating part 441 and the engaging part 445. There are two insertion mating parts 444, which are respectively arranged on one side of the vertical plate 442 and one side of the bearing plate 43;

[0061] The sliding part 449, the main sliding mating part 450 and the secondary sliding mating part 451. The sliding part 449 is slidably arranged on an elastic member 41 corresponding to the rotating part 441. The main sliding mating part 450 is arranged at one end of the top of the bearing plate 43 close to the rotating mating part 448. The secondary sliding mating part 451 is arranged on the side of the bearing plate 43 adjacent to the rotating mating part 448;

[0062] The elastic member 41 has a horizontal and a vertical state. When the elastic member 41 is in the vertical state, the folding member 42 extends to shield and protect the top of the camera. The rotating part 441 cooperates with the rotating mating part 448, the engaging part 445 cooperates with the main engaging mating part 447, and the sliding part 449 cooperates with the main sliding mating part 450, so as to limit the rotation of the elastic member 41 and not to store the folding member 42. When the elastic member 41 is in the horizontal state, the folding member 42 contracts. The rotating part 441 cooperates with the main engaging mating part 447, the engaging part 445 cooperates with the secondary engaging mating part 443, the two insertion parts 446 respectively cooperate with the two insertion mating parts 444, and the sliding part 449 cooperates with the secondary sliding mating part 451 to store the folding member 42.

[0063] The folding member 42 includes a folding cloth 421 for connecting the two elastic members 41.

[0064] Both of the two insertion parts 446 include insertion plates 4461, which are respectively fixed on the two elastic members 41. Both of the two insertion mating parts 444 include slots 4441, and are respectively opened on the same side of the bearing plate 43 and the vertical plate 442;

[0065] The rotating part 441 includes a rotating rod 4411, which is fixed on an elastic member 41. The rotating mating part 448 includes a rotating groove 4481, which is opened inside the slot 4441 on the bearing plate 43;

[0066] The engaging part 445 includes a square rod 4451, which is fixed on the other elastic member 41. The main engaging mating part 447 includes a main square groove 4471, which is opened on the bearing plate 43. The secondary engaging mating part 443 includes a secondary square groove 4431, which is opened inside the slot 4441 on the vertical plate 442;

[0067] The sliding part 449 includes a limit rod 4491 which slides through an elastic member 41. The main sliding mating part 450 includes a main limit groove 4501 which is formed at the top of the bearing plate 43. The secondary sliding mating part 451 includes a secondary limit groove 4511 which is formed at one side of the bearing plate 43.

[0068] When it is not necessary to fold and store the folding member 42 and the elastic member 41 is not stored, the two vertical sections of an elastic member 41 can be pulled, and the rotating rod 4411 can be inserted into the rotating groove 4481 to realize the rotation of an elastic member 41, and the elastic member 41 can be rotated to the vertical state. Then, the two vertical sections of the other elastic member 41 are pulled, and the square rod 4451 is first inserted into the slot 4441 on the bearing plate 43. Then, the other elastic member 41 slides in the slot 4441 on the bearing plate 43 through the square rod 4451. When the square rod 4451 slides to the main square groove 4471, the other elastic member 41 releases elastic potential energy, and the square rod 4451 is inserted into the main square groove 4471. Then, the limit rod 4491 is inserted into the main limit groove 4501 to fix the position of an elastic member 41, prevent the elastic member 41 from rotating and affecting its stability, and make it inconvenient for the folding member 42 to be extended and protected. When it is necessary to fold and store the folding member 42 and the limit rod 4491 is pulled out of the main limit groove 4501 to store the elastic member 41, the elastic member 41 at the square rod 4451 is pulled, the square rod 4451 is pulled out of the main square groove 4471, and the elastic member 41 is slid to contract the folding member 42. Then, the elastic member 41 at the rotating rod 4411 rotates in the rotating groove 4481 through the rotating rod 4411 to rotate the elastic member 41 to the horizontal state. The elastic member 41 at the square rod 4451 is inserted into the slot 4441 on the vertical plate 442. Then, the elastic member 41 at the rotating rod 4411 is pulled, and the rotating rod 4411 is pulled out of the rotating groove 4481. The rotating rod 4411 and the square rod 4451 slide in the corresponding slots 4441. At the same time, the two insertion plates 4461 are respectively inserted into the corresponding slots 4441, and the limit rod 4491 is inserted into the secondary limit groove 4511, so as to store the folding member 42 and the elastic member 41. This not only does not interfere with the installation of the camera, but also facilitates the carrying of the protection component 4, improves the practicability, and also stores the limit rod 4491, which is convenient for taking when the elastic member 41 is in the vertical state.

[0069] It should be further understood that the folding member 42 can adopt a folding cloth 421, but is not limited to adopting a folding cloth 421, which is convenient for contraction and extension.

[0070] Embodiment III

[0071] Refer to Figure 1-8 , the telescopic assembly 3 includes

[0072] The fixing plate 32 is fixed to one end of the outer wall of the rotating shaft 24;

[0073] The main telescopic member 31 is arranged on the fixing plate 32 and is used to adjust the use height of the camera;

[0074] The auxiliary telescopic member 33 is used to connect the rotating shaft 24 and the bearing plate 43.

[0075] The main telescopic member 31 uses an electric push rod, and the auxiliary telescopic member 33 uses a telescopic rod.

[0076] When it is necessary to adjust the use height of the camera, the main telescopic member 31 drives the bearing plate 43 to rise and fall, and the auxiliary telescopic member 33 undergoes corresponding telescopic changes to facilitate adaptation to different environments.

[0077] It should be further understood that the main telescopic member 31 uses an electric push rod, and a communication module is arranged in the electric push rod, which is convenient for the control system to remotely control the electric push rod. If an obstacle appears in front of the camera, the electric push rod can be started to adjust the height of the camera, ensuring the accuracy of the camera monitoring, reducing the false alarm probability of the device, and improving the stability of the device operation.

[0078] The implementation principle of a control system for warning of bad weather on highways in an embodiment of the present invention is as follows: First, the user takes the device to any highway gantry where it is needed and fixes the mounting plate 1 to the gantry with bolts. The camera monitors the situation of the highway. The control system controls the motor through the communication module in the motor control mechanism, and the motor drives the camera to rotate. The camera takes pictures of the situation of the highway, and the taken pictures are transmitted to the digital-to-analog conversion unit through the signal transmission unit for digital-to-analog conversion. The converted data is transmitted to the recognition unit in the control system. The recognition unit compares the taken pictures with the preset normal pictures. If an abnormality occurs, the data is sent to the signal output unit through the abnormal warning unit, and the warning signal is transmitted to the control center through the signal output unit for timely warning.

[0079] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
