Detailed Description
In order to make the technical scheme and beneficial effects of the present invention clearer, the following further explain the embodiments of the present invention in detail.
The system comprises a main control system, an ultrahigh detection device 100 electrically connected with the main control system, a warning device 200 and an emergency treatment device 300, as shown in fig. 1.
The main control system adopts a computer and an industrial computer, and can also adopt a control system formed by an embedded system, and is provided with a processor and an input/output interface, and is mainly used for processing data, receiving external signals and controlling external equipment. The main control system can be arranged on the upright post or the cross beam, and an electric control box can be arranged on one side of the road to install the main control system in the electric control box.
The ultra-high detection device 100 may measure the height by using an correlation device, or may measure the height by using an image recognition method.
The warning device 200 includes a beam installed on a road, and the beam 210 is disposed between the emergency detection point 100A and an overhead line. An LED sign 220 is provided on the beam. The LED signs 220 may display text to alert drivers and passengers through text content. The beam is also provided with a sound generating device 230, and the sound generating device 230 can be a tweeter, a whistle, a loudspeaker and the like. A flashing light 240 is also provided on the beam for accent cues. Meanwhile, a traffic light 250 can be arranged on the cross beam to indicate that the running vehicle stops.
In addition, the sounding device 230 and the flash lamp 240 may be disposed on the upright post for erecting the ultra-high detection device 100, so as to prompt the driver and passengers in time.
The emergency treatment device 300 is mainly used for cutting off the power supply of the overhead line in case of emergency, i.e. the supervehicle starts the emergency treatment device 300 after driving over the emergency detection point.
Specifically, the emergency treatment device 300 includes a breaking switch 310 and a switch controller. The breaking switches are respectively connected in series with the overhead lines at two sides of the road, and the switch controller is electrically connected with the main control system. The switch controller is electrically connected with the breaking switch and used for breaking the breaking switch so as to cut off the overhead line on the road. The breaking switch can be a low-voltage control switch, such as a low-voltage plastic shell breaker and the like. The switch controller can adopt a relay, and the control of the breaking switch can be realized by connecting the relay in series in a control loop of the control power supply and the breaking switch and then controlling the relay through the main control system. When the ultrahigh vehicle passes through the position of the emergency detection point, the main control system sends a signal to the relay, and the relay is driven to break the switch to ensure that the overhead line is cut off so as to reduce loss.
In addition to actively controlling overhead line power down, overhead line power down may be forced. At this time, the emergency treatment device 300 includes a ground lead, a ground resistor R connected in series in the ground lead, and an electronic control switch S. The upper end of the grounding lead is electrically connected with the low-voltage overhead line, and the lower end of the grounding lead is grounded. The electric control switch is electrically connected with the main control system. After the position of the vehicle passing through the emergency detection point is exceeded, the main control system controls the electric control switch to be turned on, the electric control switch is turned on, the overhead line is grounded after the electric control switch is turned on, and the overhead line is forced to have power failure through the grounding fault.
A first part
The ultra-high detection device 100 is an infrared correlation device or a grating correlation device which is erected at two sides of a road. The two sides of the road are provided with upright posts, and the transmitting module and the receiving module of the infrared correlation device are respectively arranged on the upper parts of the upright posts at the two sides of the road, and the heights are kept the same.
To ensure the validity of the prompt, the ultra-high detection device 100 is provided with at least three ultra-high detection devices. The ultra-high detection device is sequentially arranged at the emergency detection point 100A and the first early warning detection point 100B. The emergency detection point 100A is closest to the overhead line, the first early warning detection point 100B is farthest from the overhead line, and the first early warning detection point 100B is the first ultrahigh detection device 100 encountered by the running vehicle. The ultra-high detection devices 100 disposed between the two points may be disposed uniformly or unevenly, such as the interval between the two ultra-high detection devices 100 is smaller as approaching the overhead line. Wherein the length of the emergency detection point 100A from the overhead line may be set to 5-10m. The length of the first early warning detection point 100B from the overhead line is longer than the length of the emergency detection point 100A from the overhead line, and may be set at a position of about 30-80 m.
The direction of the first warning detection point 100B is the front with the direction of the vehicle traveling forward, that is, the direction of the emergency detection point 100A is the front.
At this time:
when the latter ultrahigh detection device 100 detects that the vehicle exceeds the limit altitude, the control warning device sends out an early warning signal and starts timing; after the preset time interval is reached, if the previous ultrahigh detection device 100 detects that the vehicle exceeds the limit height, the warning device is controlled to strengthen the early warning signal; if the previous superelevation detection device 100 does not detect that the vehicle exceeds the limit height, the warning device is stopped to send out a warning signal.
Three ultra-high detection devices 100 are provided as an example. The over-height detection device 100 located at the emergency detection point is an emergency over-height detection device 103, the over-height detection device 100 located at the first early warning detection point is a first over-height detection device 101, and the over-height detection device 100 provided between the first over-height detection device 101 and the emergency over-height detection device 103 is a second over-height detection device 102.
The method for carrying out the height early warning at the moment comprises the following steps:
when the vehicle tries the first over-height detection device 101, the first over-height detection device 101 detects the height of the vehicle, and if the receiving module of the infrared correlation device does not receive the infrared signal, the vehicle is indicated to exceed the limit height, and an accident of striking the overhead line can occur. If the receiving module of the infrared correlation device receives the infrared signal, the height of the vehicle is lower than the limit height, and the vehicle can normally pass through the limit height.
When the first ultrahigh detecting device 101 detects that the vehicle exceeds the limit height, the main control system receives a signal which is sent out by the receiving module of the infrared correlation device and exceeds the limit height, and the warning device is started to start timing at the same time, so that drivers and passengers are prompted by sounding, flashing, displaying prompt characters and the like.
After passing through the first superhigh detection means 101, if the driver finds the prompt information and turns around, the first superhigh detection means 101 does not detect the signal exceeding the limit height, and at this time, the early warning signal can be stopped. Because of the interval between the first ultra-high detection device 101 and the second ultra-high detection device 102, a time interval Tj is set. After the master control system receives the signal exceeding the height limit, starts to count time, and reaches the time limit of the time interval Tj, it is checked whether the second ultrahigh detecting device 102 detects the signal of the vehicle ultrahigh. If no indication is detected that the vehicle has slowed down and turned around, the warning signal may be stopped. If the first superelevation detection device 101 still detects the signal that the vehicle exceeds the limit height, it indicates that the driver does not notice the prompt message, and the vehicle is closer to the overhead line, and then more urgent prompt message needs to be sent. Namely, a more urgent prompt is realized by strengthening the early warning signal at this time. The reinforcing mode can be to improve the sound emitted by the sound emitting device, and improve the brightness of the flash lamp and the explosion flash frequency of the flash lamp. At the same time, the timing is started again, and the time period reached by the timing is the second time interval Te.
If the ultra-high detection device 100 is further arranged between the second ultra-high detection device 102 and the emergency ultra-high detection device 103, the pre-warning signal is reinforced again after the ultra-high detection device 100 between the second ultra-high detection device 102 and the emergency ultra-high detection device 103 detects that the limit height is exceeded.
After the second time interval is reached, the emergency superelevation detection means 103 are activated to detect the height of the vehicle. If the vehicle is not detected to exceed the limit height, the vehicle is indicated to possibly turn around, and the early warning signal is stopped at the moment. The emergency treatment device 300 is activated for power down operation if a vehicle exceeding a limit height is detected.
Since the overhead lines have a certain sag, the height of the overhead lines located in the middle lane from the ground is lower than the height of the overhead lines located at the edges. Thus, vehicles at some heights can pass through lanes with higher distances from the ground by changing lanes to the edge and passing through the overhead line when the lowest point of the overhead line cannot be passed. In this way, the sensor 400 embedded in the position corresponding to the superhigh detection apparatus 100 is installed at the lower portion of each lane to detect in which lane the vehicle is traveling, and by detecting the height of the vehicle, the passing of the vehicle conforming to the condition is dredged. Specific:
the main control system is provided with an inner lane height limit value and an outer lane height limit value. The magnitude of the inner lane height limit is less than the outer lane height limit.
In the process of system operation, besides the detection method, the following operations are performed:
when the latter over-height detection device 100 detects that the vehicle located in the inner lane exceeds the inner lane height limit value and is lower than the outer lane height limit value, the control warning device 200 sends out an early warning signal, and the early warning signal is used for prompting the over-height vehicle of the inner lane to change to the outer lane for passing.
When the latter superhigh detection device 100 detects that the vehicle located in the inner lane or the outer lane exceeds the height limit value of the outer lane, the control warning device 200 sends out a warning signal, and the warning signal is used for prompting the superhigh vehicle to decelerate and bypass.
After the set time interval is reached, if the previous superhigh detection device 100 detects that the superhigh vehicle is still positioned on the inner lane, the warning device is controlled to strengthen the early warning signal. At this time, when the sensor of the previous superhigh detection device 100 located in the inner lane is triggered, the superhigh vehicle is detected, and if the height limit value of the superhigh inner lane of the vehicle is lower than the height limit value of the outer lane, it indicates that the superhigh vehicle is still located in the inner lane, and at this time, the warning signal needs to be enhanced, and further prompts such as increasing the sound decibel number and improving the brightness of the flash lamp are provided.
After the set time interval is reached, if the previous superhigh detection device 100 detects that the superhigh vehicle is positioned on the outer lane, the warning device is controlled to stop the early warning signal. If the overtaking vehicle is changed to the outside lane, the early warning signal can be canceled when the former overtaking detection device detects that the vehicle is lower than the outside vehicle height limit value when the sensor passes through.
In the above-described detection process, whether the vehicle is an inner lane or an outer lane, the warning signal is issued as long as the height of the vehicle exceeds the outer lane height limit value, and the warning signal is enhanced when the ultra-high detection device 100 encountered in forward running detects again.
Two (II)
The vehicle height is determined using image recognition techniques. The ultra-high detection device 100 includes a camera 110 installed on the upper portion of the road, a sensor 400 embedded in the lower portion of the road, and an image recognition module installed in the main control system. The camera 110, the sensor 400 and the main control system are electrically connected. The cameras 110 include a front camera and a rear camera. The two sides of the road are provided with the upright posts, and the transverse beams are erected on the upright posts, so that the cameras can be installed on the transverse beams. The inductor 400 is buried in the lower portion of the road and is located at the front and rear sides of the cross beam, respectively. The sensor 400 is disposed between the emergency detection point 100A and the first warning detection point 100B, and the sensor 400 is disposed at both points. The sensors 400 are at least three, so as to realize detection of different distances and detection for multiple times and realize the purpose of step-by-step prompt.
The photographing mode can be adopted, and the video recording mode can be adopted. In this embodiment, video data is recorded in real time by adopting a video recording mode. One frame of data of the current video is read when the vehicle passes through the sensor. Specific:
the camera stores the recorded data into a storage system of the main control system, and in order to reduce the use of storage space, the mode of storing half-hour video data is adopted to continuously cover the previous data.
As the vehicle passes over the sensor, the sensor detects the signal of the vehicle and transmits the signal to the master control system. The master control system at this time extracts and stores one frame image of the current video data into the height identification memory.
Then, an image recognition system is started, the frame of video image is subjected to vehicle image recognition, and the height of a vehicle passing through the sensor position in the image is calculated.
Image recognition is a mature technology, and can identify different objects and differences among people to identify different individuals. The image identified in the invention is simpler and is mainly the information of the vehicle. The system can be continuously corrected through multiple tests before the system is operated so as to achieve higher accuracy.
In the image recognition process, the recognized license plate information and the position of the camera distance sensor can be used as a scale, so that the height of the vehicle is converted, and then the subsequent early warning judgment operation is carried out according to the measured height. Because the license plate is a standardized component, the shape and the size of the shot picture can be calculated in proportion to the real shape and the real size, and then the height conversion factor of the whole vehicle can be obtained.
Further, in order to improve the accuracy of detection, a plurality of sensors may be provided. All the sensors are respectively arranged on the road in the front and back directions of the cross beam. Each sensor may act as a trigger point for determining the height. Meanwhile, the positions of the plurality of sensors are different, the shot image data are also different, and the heights can be mutually corrected according to the heights measured for multiple times and calculated to be more accurate. The average height is calculated as the final height by means of an average calculation.
Based on the measured height of the vehicle, the height warning can be performed by the method for performing the height warning described in the above one.
Meanwhile, an inner lane height limit value and an outer lane height limit value can be set to control lane guidance.
An image recognition system may be employed in this embodiment to determine in which lane the vehicle is. If the image recognition system recognizes the vehicle in the inner lane, judging whether the vehicle height exceeds the inner lane height limit value and is lower than the outer lane height limit value; if so, the warning device 200 is controlled to send out a warning signal and mark the vehicle, wherein the warning signal is used for prompting the superelevation vehicle of the inner lane to change to the outer lane for passing.
Acquiring a frame of image in the video data at specific intervals, and identifying the marked vehicle and calculating the moving trend of the marked vehicle by the image identification system:
