Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Through the above technical solution, when the goods enter the customs, multiple groups of radioactive detection sensors arranged on the outside of the container will detect whether the goods are radioactive. If there is radioactivity in the goods, the data will be transmitted to the analysis and processing module. The analysis and processing module will issue a command to the indication module according to the data. The indication module will classify the goods according to the command issued by the analysis and processing module. After that, the analysis and processing module will compare and analyze the risk value of the radioactive goods with the preset risk threshold, and intercept the goods with high risk coefficients, and continuously observe the goods with low risk coefficients.

The actual risk value coefficient of the radioactive cargo in the container The actual risk factor of the radioactive cargo is Make a comparison;

like The risk level of radioactive cargo in the container is judged to be high;

Otherwise, the risk of radioactive cargo in the container is judged to be low;

Through the above technical solution, this embodiment provides the actual risk value coefficient of radioactive cargo in the container. And the actual risk value coefficient of the preset radioactive cargo The formula for the actual risk value coefficient of radioactive cargo in the container is: Obviously, the temperature and humidity in the container are the main factors affecting radioactivity, so after excluding the influence of temperature and humidity, the actual risk value coefficient of radioactive goods in the container can be obtained. And through the actual risk value coefficient of the radioactive cargo in the container The actual risk factor of the radioactive cargo is By comparing the radioactive cargo in the container, the risk level of the cargo can be determined, so as to avoid the situation where the temperature and humidity in the container will affect the radioactivity level of the cargo during the inspection, causing the staff to misjudge the risk level of the cargo.

The analysis and processing process also includes:

When it is determined that the risk of radioactive goods in the container is high, the analysis and processing module generates a traceability information code from its information code and issues a command. The execution module receives the command issued by the analysis and processing module and isolates the radioactive goods.

When it is determined that the risk level of radioactive goods in the container is low, the analysis and processing module generates an information code and issues a command. The execution module receives the command issued by the analysis and processing module to load the goods and monitors the risk level changes in real time.

Through the above technical solution, when the risk level of radioactive goods in the container is too high, the analysis and processing module will generate a traceability information code from its information code and issue a detention order. The execution module receives the order issued by the analysis and processing module and intercepts and isolates the radioactive goods. When the risk level of radioactive goods in the container is relatively low, the analysis and processing module will generate an information code and issue a continuous monitoring order. The execution module receives the order issued by the analysis and processing module to load the goods and monitor the changes in risk level in real time.

The process of monitoring risk changes includes:

Collect data evenly at preset fixed time intervals and δ(t) data;

And through the formula Calculate the correlation r between the radiation intensity of radioactive cargo and changes in environmental conditions;

Where n is the total number of data collection times, k = 1, 2, 3...n;

By comparing the correlation r between the radiation intensity of radioactive cargo and the change of environmental conditions with a preset correlation threshold r1, the preset correlation threshold r1 can be set by empirical fitting;

If r>r1, it is judged that the radiation intensity of radioactive cargo is positively correlated with the change of environmental conditions;

Otherwise, it is judged that the radiation intensity of radioactive cargo is negatively correlated with the change of environmental conditions;

Where r∈[0.8, 0.95];

As an implementation mode of the present invention, this embodiment provides a correlation r between the radiation intensity of radioactive goods and changes in environmental conditions. At this time, the analysis and processing module will compare the correlation r between the radiation intensity of radioactive goods and changes in environmental conditions with a preset correlation threshold r1. If r>r1, it is judged that the radiation intensity of the radioactive goods is positively correlated with the changes in environmental conditions. Otherwise, it is judged that the radiation intensity of the radioactive goods is negatively correlated with the changes in environmental conditions. Since r∈[0.8, 0.95], it means that the environmental conditions in the container are positively correlated with the radiation intensity of the radioactive goods. Then, in the subsequent transportation process, it is only necessary to adjust the environmental conditions to ensure that the radiation intensity of the radioactive goods will not be too high, thereby reducing the risk of radioactive goods during transportation and avoiding the situation where radioactive goods cause harm to workers during transportation.

By formula Calculate the real-time change curve of environmental conditions;

Wherein, T(t) is the real-time change curve of temperature, Y(t) is the real-time change curve of humidity, μ1 and μ2 are weight coefficients, T ₀ (t) and Y ₀ (t) are reference values of T(t) and Y(t), respectively, and the above reference values are selected and set according to the allowable temperature error and humidity error in the empirical data, T(t) and Y(t) are real-time change curves established according to the real-time data continuously monitored by the status monitoring module, and the above weight coefficients are set according to the empirical data fitting;

Through the above technical solution, this embodiment provides a real-time change curve of environmental conditions. Calculation shows that, obviously, the higher the real-time change curve of temperature is and the lower the real-time change curve of humidity is, the higher the change curve of environmental conditions is. This means that in the container, when the temperature is higher and the humidity is lower, the radiation intensity of radioactive goods will increase, thereby increasing the risk of radioactive goods. Therefore, during transportation, ensuring that radioactive goods are kept at low temperature and high humidity can avoid the increase in radiation intensity of radioactive goods, thereby avoiding the risk of radioactive goods during transportation.

The process of monitoring risk changes also includes:

By formula Calculate the average risk factor β of radioactive cargo during storage;

in, is the maximum radiation level of radioactive cargo, is the minimum radiation level of radioactive cargo, g is the proportionality coefficient, which can be set based on empirical data fitting;

If β>β1, it is judged that the average risk of radioactive cargo during storage is high;

Otherwise, the average risk of radioactive cargo during storage is judged to be low;

Through the above technical solution, this embodiment provides an average risk coefficient β of radioactive goods during storage, which is used to determine the average risk of radioactive goods during storage. The formula can be used as follows: After calculation, the average risk coefficient of radiation intensity β is compared with the standard average risk coefficient of radiation intensity β1 to judge the average risk of radioactive goods during storage. If β>β1, it is judged that the average risk of radioactive goods during storage is high, and the analysis and processing module issues an interception order, and the execution module receives the order and isolates the high-risk radioactive goods. If β<β1, it is judged that the average risk of radioactive goods during storage is low, and the analysis and processing module issues a loading order, and the execution module receives the order and loads and transports the low-risk radioactive goods.
