Preferably, the reminding system further comprises a light-emitting indication strip arranged on the lane road surface.
The road height limiting system has two height measuring methods, one is a video identification measuring method, and the other is a collision measuring method. In fact, the video identification measurement method can achieve the identification rate of more than 99% in good weather environment, and can be applied. However, in severe environments, such as rainstorm and heavy fog weather, the video identification measurement method has extremely poor identification rate and sometimes cannot be used. The system uses a collision measurement method, namely whether the height of the vehicle exceeds the standard is confirmed by whether the vehicle collides with the identification rod, and the contact identification group is not started under the general environment. The principle of the collision measurement method is that the identification rod is hung downwards, and the identification rod is provided with a damper and can resist 5-7-level strong wind, so that after an automobile touches the identification rod, the identification rod rotates relative to the portal frame, and the angular velocity indicator sends a signal at the moment, and the ultrahigh of the automobile touching the identification rod can be judged. When the recognition stick stops contacting the automobile, the recognition stick returns to the vertical position. Because in the heavy rain and the heavy fog environment, the speed of the cart which needs to be subjected to height measurement is low, and the lower part of the identification rod is made of flexible materials, the collision generated when the cart is in contact with the identification rod can not damage the cart. And the contact identification set is not a conventional means of identification.
The system is also provided with a switching identification group, namely, the video identification group or the contact identification group is determined to be used through the feedback of the switching identification group. The principle of switching the recognition group is that an additional monitor is used for watching the sign on the side of the road all the time, the sign is provided with a recognition pattern which is independently arranged, the recognition pattern is analyzed at regular time by the switching recognition group, and whether the video recognition group or the contact recognition group is switched or not is determined according to whether the recognition pattern on the sign can be accurately recognized or not.
In heavy rain and heavy fog weather, common prompting means such as a display screen and a prompt tone cannot be well used. The method of ground prompting is adopted, and the luminous indication strip is arranged on the road, so that an automobile driver can be insensitive to a display screen on the road surface, but is absolutely sensitive to the luminous indication on the road. Therefore, geomagnetism is arranged in the front and the back of the door frame, a light-emitting indication strip is arranged behind the door frame, and the light-emitting indication strip is arranged behind the back geomagnetism. The working principle of the vehicle parking system is that if a vehicle is ultrahigh, the number of the vehicles in the front and back geomagnetism and the positions of the ultrahigh vehicles are determined according to data of the front and back geomagnetism, and when the ultrahigh vehicles appear in front of the light-emitting indicator strips, the light-emitting indicator strips flicker to enable the vehicle to park by side.
Compared with the prior art, the system has two sets of height limiting identification systems, one set is a video identification system and can be used in a normal natural environment, the other set is a contact identification system and can be used in a severe environment, and the two sets of identification systems are automatically switched without manual intervention and can run uninterruptedly for a long time. The problem that only a video identification system cannot be used in all weather in the existing height-limiting identification is solved, the commercial application is really realized, and the method has large-scale popularization value.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without the need for inventive step, are within the scope of the present invention.
Example 1: as shown in fig. 1, 2 and 3, the road height limiting system comprises a recognition system and a reminding system, wherein the recognition system comprises a portal 1, the portal 1 is provided with a video recognition group 2 and a contact recognition group 3 corresponding to the positions and the number of lanes, the video recognition group 2 is a monitoring camera 21, and the contact recognition group 3 comprises a recognition rod 31 arranged on the bottom surface of a main frame of the portal 1. Still include geomagnetic sensor 5, geomagnetic sensor 5 be located portal 1 front and back and quantity are unanimous with the lane.
The identification rod 31 is connected with the main frame 1 through a rotating shaft, and a damper and an angular velocity device are further arranged on the rotating shaft. The contact identification group 3 further comprises a recovery structure, and the recovery structure comprises a recovery frame arranged on the main frame 1 and a horizontal rotating shaft arranged on the identification rod 31. The identification rod 31 is divided into two sections, wherein the upper section is made of metal material, and the lower section is made of plastic or rubber material. The identification rod 31 is wrapped with an elastic protective sleeve. The bottom of the vertical back of the identification rod 31 is height-limited height from the ground.
The system further comprises an identification environment switching system, wherein the identification environment switching system comprises a switching identification group 6 arranged on the portal 1 and a fixed point identification unit matched with the switching identification group 6 at the edge of the road. The switching identification group 6 is a monitoring camera 21, the fixed point identification unit is a sign provided with an identification pattern, the monitoring camera in the switching identification group 6 is aligned with the sign, and the contact identification group is opened or closed according to the pattern identification rate.
The reminding system is arranged behind the door frame 1 and is one or more of a display screen, a warning lamp and voice broadcast. The reminding system also comprises a luminous indication strip 6 arranged on the road surface of the lane. All reminding device all sets up behind being located portal 1 rear earth magnetism sensor 5.
Under the normal weather environment, only starting the video identification group, namely capturing the automobile picture only through the monitoring camera, obtaining the automobile height through background calculation, and when the calculated automobile height exceeds the limit height, transmitting the license plate captured at the same time to a display screen behind the door frame, and displaying the ultrahigh vehicle information through the display screen. The display screen can be a banner display screen on another portal behind the portal, and the display screen is easy to be noticed by the automobile driver. And simultaneously transmitting the information of the ultrahigh vehicles to a road administration department for processing by the road administration department.
In severe environment, whether the contact identification group needs to be started or not is judged by switching the identification group, and the principle of switching the identification group is that a single extra indicator which always faces to a roadside and is provided with an identification pattern is monitored, and the pattern is identified at regular time. The timing time may be in the interval of 6-12 hours when the weather is good and in the interval of 1-5 minutes when the weather is bad. As long as the monitoring finds that the identification pattern cannot be identified, the contact identification group is started immediately, and the video identification group is closed at the same time. When the identification can be carried out, the video identification group is turned on again if the continuous identification is successful in the unit time, the contact identification group is turned off, and the unit time is generally set to be 30 minutes.
The identification rod among the contact identification group is accomodate in the portal when not using, just vertical setting is under the portal when needs use, and when the vertical setting of identification rod, identification rod bottom is the limit for height apart from ground. The identification rod is divided into two sections, the upper section is made of metal materials, and the lower section is made of plastic or rubber materials, so that the weight of the identification rod can be guaranteed, and the elastic part of the identification rod can not damage an automobile in the collision process. Furthermore, an elastic protective sleeve such as silica gel, rubber and the like can be wrapped on the identification rod, so that the automobile cannot be damaged even if the automobile touches the metal section of the identification rod. Generally speaking, the ultra-high height of the automobile cannot touch the metal section of the identification bar. Because the identification rod can rotate to service environment is bad weather, has the suspicion of superelevation all to be the cart under this kind of environment, and their speed of a motor vehicle can all become low this moment, and the car can not cause the potential safety hazard with the identification rod collision under the low speed of a motor vehicle. In order to ensure that the identification rod is vertical all the time in a natural state, a damper is arranged on a rotating shaft connected with the door frame, and the identification rod can be kept in a vertical state under 7-level strong wind in the embodiment. And by adjusting the damping coefficient, the identification rod can resist greater separation. And an angular velocity indicator is also arranged on the rotating shaft, and when the identification rod rotates after colliding with the automobile, the angular velocity indicator generates data to determine that the automobile is ultrahigh.
Under severe weather, if reminding the ultrahigh vehicle is also a difficult problem, the system adopts an additional reminding mode after starting the contact identification group. When the contact recognition group is activated and the video recognition group is simultaneously turned off, the position information of the vehicle on the lane cannot be obtained. Therefore, the front side and the rear side of the door frame are provided with the geomagnetic sensors, and each lane is provided with a front geomagnetic sensor and a rear geomagnetic sensor which are used for judging the number and the positions of the vehicles. The number of the automobiles between two geomagnetisms can be determined through data of the front geomagnetic sensor and the rear geomagnetic sensor, the positions of the automobiles between the two geomagnetisms can be roughly determined through geomagnetic waveforms, particularly, the automobiles passing through the contact identification group can be roughly determined, the ultrahigh vehicles can be locked immediately once collision occurs, and the reminding system at the moment is not a display screen any more, because most drivers cannot clearly see the content of the display screen in severe weather. The additional reminding device is a luminous indicating strip positioned behind the geomagnetic sensor behind the portal frame, and when the ultrahigh vehicle drives away from the geomagnetic sensor, the luminous indicating strip is luminous to remind the ultrahigh vehicle of the abnormality of the ultrahigh vehicle. Since the driver is more concentrated on the road itself and in front of the road in bad weather, the luminous indication strip on the lane is luminous, so that the driver can easily notice and take corresponding actions. Whereas road lighting is significant even in heavy rain and fog weather.
The system really achieves height limit detection in all weather, can be used normally and uninterruptedly in normal weather and severe weather, and can exceed higher detection precision.
