Abstract

[0002] The rapid and sustained economic and social development has led to the rapid growth of the logistics industry. Road freight transport plays a crucial role in my country's comprehensive freight transportation system. However, correspondingly, road transport accidents are also the most frequent and most devastating, accounting for over 85% of dangerous goods transport accidents. During transportation, dangerous goods, if exposed to heat, collision, vibration, and other triggering factors, are highly susceptible to major accidents such as fires and explosions, resulting in economic losses, environmental pollution, ecological damage, casualties, and a host of other social problems.
[0003] Currently, there are numerous hazard warning detection devices used in the road transport of dangerous goods in China, and they have been widely promoted and applied to a certain extent. However, some problems still exist in their actual use. For example, existing detection devices for dangerous goods transport vehicles are generally only able to monitor vehicle positioning data or single operating status data such as tire pressure and oil temperature, and are unable to provide real-time monitoring of the cargo status of the vehicle while in motion. Therefore, there is a need to design a system that can monitor the temperature status of cargo in a moving vehicle and transmit this information in real time to a central monitoring room for timely processing. It should also be simple in design, easy to operate, and easy to market. Summary of the Invention

[0030] The present application will be described in detail below in combination with the drawings and specific embodiments. The component model, material name, connection structure, control method, algorithm and other features not explicitly described in this technical solution are all considered as common technical features disclosed in the prior art.
[0031] The road transport thermal imaging dynamic temperature monitoring system in this application includes a road monitoring assembly and a central monitoring terminal 4, which is specifically described in Figure 1 and Figure 2 .
[0032] The road monitoring assembly includes a plurality of infrared monitoring modules 3 arranged along the length direction of the road; the plurality of infrared monitoring modules 3 are all in communication connection with the central monitoring terminal 4, and the central monitoring terminal 4 is a computer terminal where the detector is located.
[0033] The infrared monitoring module 3 comprises a thermal imaging probe array 1 arranged along the two sides and the top of the road, and a sub-processor 2 in communication connection with the thermal imaging probe array 1. When the cargo transport vehicle 5 passes through the infrared monitoring module 3, the infrared monitoring module 3 obtains the thermal images of the two sides and the top of the cargo transport vehicle 5, and the sub-processor 2 deducts the self-heating part of the vehicle body from the thermal images and sends them to the central monitoring terminal 4, which displays and stores the thermal images of the cargo transport vehicle 5 at multiple positions on the road in a tracking manner.
[0034] The thermal imaging probe array 1 is arranged along the cross section of the width direction of the road. The sub-processor 2 is an FPGA, or one selected from an x86 architecture, an ARM architecture, and a RISC-V architecture processor. The thermal imaging probe array 1 comprises a plurality of thermal imaging probes, each of which is in communication connection with the sub-processor 2.
[0035] Each thermal imaging probe array 1 contains at least a camera arranged on the two sides of the road and the top of the road, so as to obtain two side-view thermal images and one overhead thermal image of the cargo transport vehicle 5. The sub-processor 2 is provided with a sub-memory, in which a vehicle self-heating data model is pre-set. The sub-processor 2 deducts the background heat value of the self-heating part in each thermal image based on the vehicle self-heating model. The interval between two adjacent infrared monitoring modules 3 is 1-100 km.
[0036] When the above monitoring system is used for road transport thermal imaging dynamic temperature detection, the following steps are included:
[0037] S1: obtaining two side-view thermal images and one overhead thermal image of the target vehicle at a first position on the road;
[0038] S2: deducting the background heat value of the self-heating part in each thermal image based on the vehicle self-heating data model to obtain the final thermal image;
[0039] S3: obtaining the final thermal image of the target vehicle at other positions on the road in a tracking manner, and displaying and storing it in the central monitoring terminal 4 in a tracking manner, so as to obtain the heat information of the cargo transport vehicle 5 on the road. The tracking display can be based on the license plate to determine the vehicle.
[0040] The vehicle self-heating model is a mapping model of vehicle body size-thermal image. The mapping model is obtained by training the data set of vehicle body size-thermal image of an empty vehicle on the road.
[0041] In the implementation, the thermal imaging probe array 1 can be installed in the tunnel or a specially built bridge, and is distributed along a cross section, and the number thereof should be able to ensure no blind area. When the train or vehicle loaded with goods passes, the fixed probe is in a scanning state relative to the moving vehicle, and converts the infrared thermal radiation into corresponding electrical signals. The sub-processors amplify and video process the electrical signals collected by the thermal imaging probe, and form a thermal imaging image that can be observed by naked eyes, reflecting the temperature distribution state of the target surface. The application software identifies the normally heating part (such as the engine, etc.) in the goods transport vehicle, and gives an exclusion. The central monitoring terminal 4 in the central monitoring room receives the identified abnormal heating information of the road goods transport vehicle, and further finds out the situation (such as the type of goods, etc.), and gives a timely treatment, so as to achieve the effect of collecting the goods transport state information in real time, monitoring the dynamic temperature state of the goods, and preventing major accidents.

The person skilled in the art can obviously easily make various modifications to the embodiments, and apply the general principles described herein to other embodiments without having to undergo creative labor. Therefore, the invention is not limited to the above embodiments, and the improvements and modifications made by the person skilled in the art according to the disclosure of the invention without departing from the scope of the invention should be within the protection scope of the invention.
