Description

Technical Field

[0001] The invention relates to the field of infrared thermal imaging monitoring technology and road asphalt paving engineering technology, and in particular to a highway asphalt paving temperature real-time monitoring system (thermograph). Background Art

[0002] A thermal imager is essentially a heat sensor that can detect and capture tiny temperature differences. It collects infrared radiation from objects in the scene and creates pixels and images based on information about the temperature differences. Since objects are rarely exactly the same temperature as surrounding objects, thermal imagers can detect their differences and create sharp contrast in the thermal image.

[0003] The optimal temperature range for paving asphalt pavement on highways is usually between 110℃ and 130℃, but not more than 165℃. In the specific construction process, the control of paving temperature is very important. Too high temperature may cause asphalt aging and affect the durability of the pavement; while too low temperature may lead to insufficient compaction and affect the flatness and strength of the pavement. Therefore, in the construction process, the temperature at each stage must be strictly controlled to ensure that the asphalt pavement achieves the expected service life and performance.

[0004] In order to control the temperature of highway asphalt paving and reduce the damage caused by temperature segregation to the asphalt pavement, it is necessary to monitor the asphalt paving temperature. Traditional temperature monitoring methods often have problems such as inaccurate monitoring, poor real-time performance, and large randomness, which are difficult to meet the needs of modern highway construction for high quality and high efficiency. Therefore, it is of great significance to develop a system that can monitor the temperature of highway asphalt paving in real time. Summary of the invention

[0005] The purpose of the present invention is to provide a real-time monitoring system (thermograph) for highway asphalt paving temperature, which can monitor the temperature during the asphalt paving process in real time and improve the paving quality and efficiency.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the real-time monitoring system (thermograph) of highway asphalt paving temperature includes a data acquisition device, a data storage and analysis system, and a low temperature alarm device.

[0007] Preferably, the data acquisition device includes an infrared thermal imaging camera, a GPS real-time positioning device, and a gyroscope.

[0008] There are two infrared thermal imaging cameras with a resolution of 256x192, which collect temperature data of the entire asphalt paving in real time and transmit it to the data storage and analysis system in real time;

[0009] The GPS real-time positioning device locates the equipment, collects and monitors the paving speed and paving trajectory in real time, and transmits them to the data storage and analysis system in real time;

[0010] The gyroscope is built into the acquisition device, and can obtain the posture information of the device in real time, and transmit it to the data storage and analysis system in real time.

[0011] Preferably, the data storage and analysis system is a system mainboard, which is connected to the data acquisition device and the low temperature alarm device via a data cable, and is connected to the display screen via HDMI.

[0012] The present invention is implemented in this way: a real-time monitoring system for highway asphalt paving temperature (thermograph) comprises the following steps:

[0013] Step 1: Turn on the device and log in to the system;

[0014] Step 2: Paving project settings, create a project, set parameters, and import road centerline coordinates;

[0015] Step 3: Data collection: the data collection device starts working to monitor the asphalt paving of the highway in real time, and transmits the collected monitoring data to the data storage and analysis system in real time for display, storage and analysis;

[0016] Step 4: The data storage and analysis system displays the highway asphalt paving temperature image in real time, automatically stores the temperature data, and automatically triggers an alarm signal when the temperature reaches the set low temperature threshold;

[0017] Step 5: The low temperature alarm device issues an alarm based on the low temperature signal sent by the data storage and analysis system. When the collected asphalt temperature is too low and reaches the low temperature threshold, a red light alarm is displayed to facilitate construction personnel to control the highway asphalt paving temperature in a timely manner.

[0018] Preferably, in step one, specific operations include: powering on the device and logging into the system.

[0019] Preferably, in step 2, the parameter settings specifically include: project name, coordinate conversion parameters, paving width, paving thickness, underlying layer temperature, asphalt type, serial port number, etc.

[0020] Preferably, in step three, the collected data includes: real-time temperature of the asphalt paving of the road surface, paving trajectory, equipment posture and other information.

[0021] Preferably, in step 4, the data display interface specifically includes the following information: a two-dimensional matrix color change image of temperature along the route is displayed in the main interface, with the low temperature area being red, the normal area being green, and the critical area being yellow. The left side displays data information such as project name, camera height, yaw angle, tilt angle, scanning distance, resolution, target width, and low temperature limit. The upper side displays data information such as the lowest temperature, average temperature, highest temperature, and paving width.

[0022] The beneficial effects of the present invention are:

[0023] 1. Real-time monitoring of the temperature during asphalt paving to improve the quality and efficiency of highway asphalt paving;

[0024] 2. Provide construction suggestions through big data storage and analysis to facilitate construction inspection and optimize construction technology;
