Detailed Description
The system of the present invention will be described in further detail with reference to the accompanying drawings and embodiments of the invention.
The invention relates to an asphalt temperature segregation infrared detection system of a paver, which mainly comprises an electric subsystem and a data analysis subsystem. The electric subsystem is used for detecting asphalt temperature segregation during road construction and storing data.
Fig. 1 is a schematic structural diagram of a mechanical support device of an electrical subsystem of an infrared detection system according to the present invention, and as shown in fig. 1, the mechanical support device (also called a reference beam) mainly functions to support the electrical subsystem of the infrared detection system, and can support all components of the electrical subsystem, and arrange infrared probes in a line at a certain interval. This mechanical support device mainly includes: the main beam comprises a main beam support frame 1, a main beam (called as the main beam for short) 2 of a reference beam, a main beam connector 3, fixing seats 4 and 5 of the support frame and the like.
When the device is used, different numbers of main body beams 2 are selected according to different requirements of actually measuring the width of a road surface, the length of each main body beam 2 is two meters, the device can be used for measuring the road surface with the width of 2 meters at one time, and if only one main body beam 2 is provided, the main body beam connector 3 is not required to be configured; if the road surface is wide, a plurality of main body beams 2 are needed to cover the road surface, and a certain number of main body beam connectors 3 are correspondingly needed to be matched, so that the main body beam connectors 3 meet the requirement for road surface coverage by connecting the plurality of main body beams 2. However, no matter how many main body beams 2 are selected, at least two main body beam support frames 1 are needed, and the main body beam support frames 1 are connected through the fixing seats 4 and 5 of the support frames. Wherein, the number of the fixed seats 4 of the support frame is the same as that of the main body beam support frame 1. Assuming that the number of body beams 2 is N, the number of body beam connectors allowed is N-1; when the road surface width is below 2 meters, 1 section of the main body beam 2 is needed to meet the requirement, in other words, when N sections of the main body beams 2 are used, the width capable of covering the road surface is 2N meters. N is a natural number greater than or equal to 1.
The infrared detection system can measure a road with the width of 8 meters at most, so that according to the configuration, at most four main body beams 2, three main body beam connectors 3, two main body beam support frames 1 and two sets of fixing seats 4 are required to be selected. Under the condition that the number of the main body beams 2 is increased, the number of the main body beam support frames 1 can be also increased properly so as to ensure that the beam body does not droop and maintain the levelness of the beam body, and the stability of a detection result can be ensured. The products developed before all adopt whole benchmark roof beam, support with the wheel, outside it is independent of the machine, still need operating personnel manual drive, because the roof beam body does not divide the body, cause the installation difficulty, flexibility and mobility are relatively poor. The reference beam adopts the split connection mode, is arranged on the screed pedal of the paver when in use, is convenient and quick, and greatly saves labor by changing manual drive into machine drive.
When the device is installed, the main body beam 2 part of the reference beam is connected together through the main body beam connector 3, one end of each support frame fixing seat 4 and 5 is in threaded connection with the pedal of the paver screed plate through bolts, the main body beam support frame 1 is inserted into the other end of each support frame fixing seat 4 and 5, and the main body beam support frame can be fixed through rotating the clamping handle. Then the main body beam 2 connected by the connector 3 is erected on the main body beam supporting frame 1, and the main body beam 2 is fixed by the movable hinge on the main body beam supporting frame 1. The advantage of this design is that the main body beam 2 can be moved freely in the direction of advance of the paver, facilitating the operator to freely adjust the distance between the main body beam 2 and the screed of the paver so that it is in the optimum position of the machine that does not impede the operation of the operator.
The electric device of the electric subsystem of the infrared detection system further comprises 1 main operation panel, a plurality of infrared probes (the specific number is determined according to the width of a road surface to be detected), 1 distance measurement sensor, 1 GPS global satellite locator, 1 Flash Memory, 4 digital/analog conversion boxes and a plurality of connecting cables.
The process of mounting the mechanical support (reference beam of the infrared detection system) shown in fig. 1 in conjunction with the electrical subsystem is described below:
firstly, the number of the infrared probes is selected according to the width of the road surface to be detected, the default configuration is that 6 probes are arranged on the road surface with the width of 2 meters, and the width of the probes can be properly increased or decreased according to the width of the road surface. The maximum detection width of the infrared detection system is 8 meters, so that 24 infrared probes are required in total, namely 3 infrared probes are required for detecting a road surface with the width of one meter. According to this configuration rule, if the reference beam is 2 meters long, a total of 6 infrared probes need to be installed, specifically: and evenly dividing the reference beam with the length of 2 meters by 6 equal parts, drilling mounting holes, and fixing the infrared probe on the reference beam.
Secondly, the installation of the digital/analog conversion box. Each set of infrared paving detection system is provided with 4 digital-to-analog conversion boxes which are respectively marked as digital-to-analog conversion boxes ID1, ID2, ID3 and ID 4. In the using process, each digital-analog conversion box is not used, the number of the digital-analog conversion boxes to be started is determined according to the width of the road surface to be detected, and according to the rule, the equipment is completely used, namely when the road surface to be detected in construction is 8 meters wide, all 4 digital-analog conversion boxes are required to be used. After the required number of digital/analog conversion boxes is selected, the digital/analog conversion boxes are fixedly installed on the reference beam through bolts.
In the use state, the digital/analog conversion box is used for connecting the infrared probe and transmitting data detected by the infrared probe to the main operation panel. Each digital-to-analog conversion box can be connected with 6 infrared probes. In other words, the main function of the dac box is to convert the analog signal of the temperature detected by the infrared probe into a digital signal. Because the signals used by the infrared detection system are all digital signals, the invention adopts a Controller area network Bus (CAN Bus) which is widely applied in the industries of automobiles and engineering machinery as a digital interface.
Here, the above-mentioned digital/analog conversion cassettes are numbered in order from ID1 to ID4, and also have a role of: all infrared probes can be distinguished in a left-to-right (or right-to-left) direction, looking at the reference beam along the direction of travel of the assigned number paver. Like this, when one of them infrared probe broke down, constructor can fix a position the fault point rapidly, and the trouble is got rid of to guarantee going on smoothly of detection achievement.
The distance measuring sensor is fixed at the center of the driving wheel of the paver and is connected to the operation panel and the digital/analog conversion box through a cable, so that the distance traveled by the paver can be conveniently calculated by counting the number of turns of the driving wheel of the paver in unit time.
The operation panel of the paver is arranged on an instrument panel of a cab of the paver, so that a driver of the paver can conveniently operate the operation panel.
The GPS global positioner is arranged at the top end of the machine cab and is connected with the operation panel by a cable, and the flash memory is directly inserted on the operation panel and is used for storing the detection data obtained by the infrared detection system.
Fig. 2 is a schematic diagram of the working flow of the electrical subsystem of the infrared detection system, i.e. the detection process, as shown in fig. 2, which is as follows. After the infrared detection system is installed, the power line is connected with a storage battery of the paver, and then the system can be started.
And step 21, presetting a system. After the system is powered on and started, a construction operator firstly needs to establish an engineering management project through an operation panel, namely, a detection project is established for each detection, so that specific engineering management and data query are facilitated. In the process of establishing the engineering management project, two modes are selectable: one is to create a new project and the other is to select one of the original projects (i.e. one that has not been completed before or has been completed to a certain stage) and proceed. The method specifically comprises the following steps:
a new management item is established, and the operation is completed through the operation panel. The two modes can be completed by operating keys defined differently on the panel, and can also be completed by touch screen (also can be completed by key) input.
Therefore, a constructor can establish a new management item by touching and pressing an icon of the new item or a key corresponding to the icon.
And step 22, after the project is established, setting the project by an operator.
Step 221, the operator may enter the operator's name, the name of the current road being constructed, the starting location, a personal description of the project, the paving thickness, the lowest temperature color (e.g., blue or brown), the highest temperature color (e.g., magenta or red), the paving layer number, the radius of rotation of the ranging sensor (which refers to the distance between the center location where the sensor is mounted and the ground), the location where the ranging sensor is mounted (along the direction of travel of the paving machine, on the left or right side of the machine), the units of distance (meters or feet, etc.), and GPS base station location compensation, the number of nearest base stations, the distances between each base station, and the arrangement between the base stations. The method for newly building the management project is suitable for detecting a newly started project.
Step 222, another setting manner in parallel with the step 221: is to open a project that has been previously set up. This approach is suitable for intermittent, already-established project engineering continuation. In this way, the log file of the project detection management item which is already established can be changed.
And step 23, after the setting process is finished, clicking a confirmation key, and enabling the program to enter an initialization process. The system prompts confirmation of the selected infrared probe and information of other devices installed and selected to be used in the system.

The inclined line area, the shadow area and the dot area respectively correspond to the purple red, the red and the yellow on the display screen, the corresponding temperatures can be distributed in the range of 350-260 ℃ (temperature values can also be displayed by a Fahrenheit temperature scale), and the purple red, the red and the yellow areas can present gradually-changed transition color steps due to the non-uniformity of the temperature distribution of the asphalt pavement. Fig. 3 represents a color distribution, viewed from a display screen, representative of reliable pavement paving quality during normal paving operations. However, the temperature value range that the system can display is displayed in colors of red, orange, yellow, green, cyan, blue, brown, gray and the like from high to low, and the corresponding temperature value range can be displayed between 1000 ℃ and minus 40 ℃. The temperature distribution of the current heat map can be graphically displayed by establishing temperature levels, and can also be graphically displayed by setting a target temperature, such as setting 225 degrees fahrenheit as the target temperature, with every 50 degrees as the range temperature, the first temperature level starting at 200 degrees fahrenheit and ending at 250 degrees fahrenheit; the other levels are analogized.
Fig. 4 is a schematic temperature diagram of the material segregation situation displayed on the operation panel of the infrared detection system of the present invention, as shown in fig. 4, a woven area, a diagonal area, a blank area and a shaded area respectively represent the temperature distribution situation of the road paving asphalt, and the woven area, the diagonal area, the blank area and the shaded area sequentially correspond to red, yellow, green and blue areas on the display screen, and respectively represent the temperature distribution situation from high to low. Similarly, the red, yellow, green and blue regions may also exhibit gradual transition colors due to non-uniformity of the temperature distribution of the asphalt pavement, so that the boundaries of the regions are not very distinct as shown in the figure. Wherein, the areas with lower temperature represented by blue and green (the temperature range is approximately distributed between 260 ℃ and 180 ℃), the quality problems of insufficient pavement compactness or large gaps under the pavement exist, the images detected by the infrared probe and displayed on the display can be intuitively grasped so as to be processed in time at the current site, the processing mode comprises passing practices such as material supplement, pressure supplement and the like, and the contents containing the information such as the images and the like can be stored in the flash memory so as to be consulted and analyzed by a construction party and a supervision party.
Fig. 5 is a schematic temperature diagram of a parking waiting condition displayed on an operation panel display screen of the infrared detection system of the present invention, and as shown in fig. 5, the distribution of a dot region, a rough twill region, a fine twill region, and a shadow region represents a road surface temperature distribution condition when a paving material is to be added during parking, and the dot region, the rough twill region, the fine twill region, and the shadow region respectively correspond to red, blue, green, and brown colors on the display screen, and also respectively correspond to a heat image profile distribution condition from high to low in temperature.
In addition, during the real-time monitoring process of the system, the information displayed on the display screen of the system contains the following:
1. the method comprises the steps of scanning road surface information point by point in real time according to the corresponding relation that the temperature is changed from high to low corresponding to the warm tone of the color as shown in figures 3-5 (displayed in a form of a heat image window or a full screen mode), displaying the geographical position information of the system on a display screen in real time, and displaying the geographical position information in a longitude and latitude mode after the geographical position information is positioned by a GPS (global positioning system) positioner.
2. The information of the distance traveled by the infrared detection system, namely the paver and the corresponding time information are reflected in real time. The unit of the distance can be English system or metric system, and the selection between the English system and the metric system can be conveniently switched.
3. The travelling speed of the paver is reflected in real time.
All of the above can be stored in flash memory accompanying the system.
In addition, during the construction, the constructor can also realize the following operations through keys arranged on the operation panel: including pausing the data scan, switching to a full screen temperature data scan interface, browsing the scanned data, etc. When the construction is finished, the operator presses the stop key to show that the construction is finished, and the construction data result generated by the system is displayed on the display screen one by one in the form of taking the project name as the subject. Constructors can look up each record according to own needs. All construction record information is stored in the flash memory, and can also be stored in an internal memory of the system. But the final result requires flash memory to transfer the data to another computer.
During construction, if the system finds that a selected instrument is out of order, the system will send out an alarm signal and display the specific instrument on the display screen. PC computer operation: finally, the data analysis subsystem of the infrared detection system is utilized to analyze the data result detected by the electric subsystem on a PC computer and form a specific detection analysis report. The data of the detection project established by the system in the construction process can be copied to a computer through a flash memory, and the project management software, namely PPM, is opened, and finally a report in PDF format can be formed for output, so that the data can be conveniently referred and analyzed by a constructor and a supervisor.
