Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-3 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application discloses a highway dynamic vehicle axle counting weighing and collecting system. Referring to fig. 1, the dynamic vehicle axle-counting weighing and collecting system on the highway includes a plurality of vehicle overload detecting subsystems 1 for detecting the overweight behavior of each vehicle running through the same lane, so as to detect the overweight behaviors of all vehicles and increase the applicability of the vehicle overload detecting system.
Since all the vehicle overload detecting subsystems 1 are the same, the present application will be described in detail by taking one of the vehicle overload detecting subsystems 1 as an example.
The vehicle overload subsystem comprises a quality detection module 2, an image acquisition device 3, an image identification module 4 and a control module 5;
referring to fig. 1 and 2, the quality detection module 2 is disposed on the sensing board 10. Specifically, the induction board 10 is placed on the expressway. A plurality of areas are divided on the induction plate 10 according to the arrangement mode of the lanes, each area corresponds to one lane, and a quality detection module 2 is installed in each area. The quality detection module 2 is used for detecting the weight of each automobile in the lane and outputting a quality detection signal.
The quality detection module 2 comprises a processing unit 22 and a plurality of quality sensors 21;
the plurality of mass sensors 21 are uniformly distributed in corresponding areas on the sensing plate 10. The mass sensor 21 is used for detecting the weight of each automobile in the lane and outputting a mass acquisition signal. Of course, the mass sensor 21 may also employ other instruments for sensing mass.
The processing unit 22 is connected to the mass sensors 21, and is configured to receive and process the mass acquisition signals, calculate the weight of each vehicle in the lane, and output a mass detection signal. It will be appreciated that the vehicle is subject to random and impact loads and a number of external factors during its movement. Such as air resistance and the operation level of a driver, the complexity of the automobile movement is increased to a certain extent, and the objectivity and the accuracy of weighing results are influenced to a certain extent. For this purpose, the processing unit 22 is capable of processing several received quality acquisition signals, and accurately calculating the weight of each vehicle in the lane. Preferably, the processing unit 22 is a MCU.
The image acquisition device 3 is used for shooting each automobile driven in the lane and outputting an acquired image of the automobile.
In the present application, the image pickup device 3 includes a plurality of cameras. Each camera is arranged on different positions and is used for shooting each side of each automobile in the lane and outputting an image collected by the automobile. Wherein, mainly shoot the front, back, left and right sides of every car. Of course, other cameras may be used.
The image recognition module 4 is respectively connected with a plurality of cameras and used for receiving a plurality of vehicle collected images, recognizing the model of each vehicle according to the vehicle collected images and outputting a vehicle model signal representing vehicle model information. It should be noted that the models herein refer to small, neutral and large. Of course, medium and small sizes and medium and large sizes can be further increased. By identifying the images of the front, the rear, the left and the right of each automobile, the model of the automobile can be identified more accurately. The image recognition module 4 is a conventional technique for those skilled in the relevant field, so the recognition principle will not be further described in the embodiment of the present application.
The control module 5 comprises a first control unit 51. The first control unit 51 is connected to the quality detection module 2 and the image recognition module 4, respectively. The first control unit 51 is preset with a plurality of overweight guard values, each corresponding to a model. The first control unit 51 is configured to output an overweight signal to the monitoring platform when the weight value reflected by the quality detection signal reaches a corresponding overweight guard value. This enables the first control unit 51 to match the corresponding overweight guarding values according to the vehicle model to judge the overweight behaviors of the vehicles of different models, i.e. it means that the first control unit 51 can judge the overweight behaviors of all vehicles, and the application range of the vehicle overload detection system is expanded. In contrast, when the weight value reflected by the mass detection signal is lower than the corresponding overweight guard value, the first control unit 51 does not output the overweight signal. Wherein, the monitoring platform is used for processing and showing overweight signal to the staff carries out the fine or other operations.
It is considered that the weight of some overloaded vehicles not only exceeds the corresponding overweight guard value, but also exceeds the maximum range of the mass detection module 2. When the mass sensor 21 of the mass detection module 2 reaches a full bias state for many times, the problem of zero drift is easily caused, and even the service life of the mass sensor is shortened. Therefore, the frequency of the quality sensor 21 reaching the full bias can be counted, and the quality sensor can be periodically overhauled based on the frequency.
Specifically, the vehicle overload detection subsystem 1 further includes an electronic tag 6 disposed in each area on the induction board 10.
The first control unit 51 is further configured to output a full bias signal when the weight value reflected by the quality detection signal reaches a preset maximum load value. Wherein, the maximum bearing value is the maximum weight that the quality detection module 2 can bear. When the mass detection module 2 detects that a certain vehicle is overloaded and the weight reaches the maximum load value, it indicates that the mass detection module 2 is in a full bias state at this time. Otherwise, when the quality detection module 2 detects that a certain vehicle is not overloaded or the overload does not reach the maximum load bearing value, the quality detection module 2 does not output the full bias signal.
The control module 5 further comprises a second control unit 52. The second control unit 52 is connected to the first control unit 51, and is configured to count the number of times that the full offset signal is received, and output an overhaul signal when the number of times exceeds a preset number of times alarm value. By counting the number of times the full-bias signal is received, the service life of each quality detection module 2 can be clearly grasped. When the number of times exceeds the preset number of times alarm value, it indicates that the staff needs to overhaul or replace the quality sensor 21 in the quality detection module 2. On the contrary, when the number of times does not reach the number-of-times alarm value, the second control unit 52 does not output the maintenance signal. Preferably, the second control unit 52 is also provided with a reset function to re-count the number of times the full bias signal is received after the quality sensor 21 is overhauled or replaced. Wherein the service signal is used to mark the electronic label 6.
It will be appreciated that each electronic tag 6 is connected to a respective second control unit 52. Only when the second control unit 52 outputs the overhaul signal will the corresponding electronic tag 6 be marked with content. In contrast, when the second control unit 52 does not output the service signal, no information is stored in the electronic tag 6.
Further, the worker can hold the detection device to identify all the electronic tags 6 on the sensing board 10 periodically. When the detection device communicates with the blank electronic tag 6, no information can be read. But when the detection device communicates with the tagged electronic tag 6, a service signal can be read. Based on this, the worker can know which mass sensors 21 need to be repaired or replaced.
Preferably, the first control unit 51 and the second control unit 52 are both FPGAs, and the maximum weight bearing value, the number warning value and the multiple overweight warning values can be adaptively adjusted according to actual situations.
Referring to fig. 1 and 3, of course, for some trucks, the loaded cargo volume is large, and it can be determined from the surface that the truck is in an overload state. Therefore, the vehicle overload detection subsystem 1 of the embodiment of the present application further includes a triggering device 7, a height measuring device 8 and a warning device 9.
The triggering device 7 is disposed on one side of the sensing plate 10 facing the driving direction of the vehicle, and is located at a first preset distance from the sensing plate 10, and is used for detecting whether the vehicle passes through and outputting a triggering signal when the vehicle passing through is detected. The triggering device 7 is preferably a proximity switch or a pressure switch.
The height measuring device 8 is disposed on a side of the sensing plate 10 facing the driving direction of the vehicle, and is spaced apart from the sensing plate 10 by a second preset distance, and is configured to measure the height of each vehicle on the lane when receiving the trigger signal, and output a height detection signal. It should be noted that the height measured by the height measuring device 8 is the height added to the cargo, and not the height of the car itself. Preferably, the height measuring device 8 is an ultrasonic distance meter.
The first preset distance is larger than the second preset distance, so that after the vehicle passes through the triggering device 7, when the height measuring device 8 measures the height of the vehicle, the vehicle just reaches the position of the height measuring device 8.
The first control unit 51 is connected to the altitude measuring device 8 for outputting an alarm signal when the altitude value reflected by the altitude detection signal exceeds the altitude warning value, so that the operator is notified of the interception when the altitude of the vehicle exceeds the altitude warning value. On the contrary, when the altitude value reflected by the altitude detection signal does not exceed the altitude warning value, the first control unit 51 does not output the alarm signal. The altitude warning value is also a preset numerical value, and can be adaptively adjusted according to the actual situation.
The alarm device 9 is connected to the first control unit 51 for alarming upon receiving the alarm signal. Preferably, the alarm device 9 is a sound and light alarm.
It should be noted that the embodiment of the present application can be applied not only to an expressway but also to a high-speed toll station, and only needs to be adaptively adjusted according to needs.
The implementation principle of the dynamic vehicle axle counting, weighing and collecting system for the expressway in the embodiment of the application is as follows: the vehicle overload detection system is arranged on each lane, so that the quality detection module 2 can collect the weight of all vehicles, the image recognition module 4 can recognize the models of the vehicles according to the collected images of the vehicles to match the corresponding overweight warning values and judge the overweight behaviors of the vehicles, and further the vehicle overload detection system has a good application range and can accurately judge the overweight behaviors of all the vehicles.
The foregoing is a preferred embodiment of the present application and is not intended to limit the scope of the application in any way, and any features disclosed in this specification (including the abstract and drawings) may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
