In further examples, the monitoring devices carried by the inspection robot include, but are not limited to, cameras, various types of sensors (e.g., temperature sensors, humidity sensors, smoke sensors, gas sensors), navigational positioning devices, and the like.
The inspection speed planning module is used for calling the historical inspection log of the highway tunnel to plan the inspection speed corresponding to each tunnel section, and the specific operation is as follows: and extracting the inspection results of each tunnel section in each inspection log from the historical inspection logs, further selecting the inspection log with the abnormal inspection result as the abnormal inspection log, and counting the number and abnormal directions of the abnormal inspection logs, wherein the abnormal directions are traffic road conditions or traffic environments.
The method is characterized in that the current time is limited when the historical inspection logs are extracted, the situation that the current tunnel condition cannot be reflected due to the fact that the extracted historical inspection logs are too long is avoided, the reference value for the inspection speed planning is further lost, the number of the extracted historical inspection logs is not too small, the number of the historical inspection logs extracted is not less than 5 in an exemplary mode, and the influence on the inspection speed planning accuracy caused by too small inspection result data is avoided.

In the above example, the average exception handling duration corresponding to the traffic condition and traffic environment is the exception direction is the traffic condition、Then，。
The reason that the abnormal processing time length of the traffic road condition and the traffic environment in the history inspection log is taken as the corresponding weight factors of the traffic road condition and the traffic environment is that the abnormal processing time length can reflect the actual influence degree of the traffic road condition and the traffic environment, and the longer abnormal processing time length usually indicates that the road condition or the environment problem is serious and possibly has great influence on traffic, so that the abnormal processing time length can be taken as an important index of the weight factors, and in addition, the abnormal processing time length is an objective and quantifiable index and can intuitively reflect the conditions of the traffic road condition and the traffic environment. The actual situation can be converted into a digital index by taking the abnormal processing time length as a weight factor, so that quantitative evaluation and comparison analysis are facilitated.
It is to be noted that the history inspection log includes the monitoring results of the traffic road condition and the traffic environment, when the traffic road condition is abnormal, the abnormality points to the traffic road condition, and when the traffic environment is abnormal, the abnormality points to the traffic environment, and in addition, the history inspection log also includes the processing time for monitoring the abnormality.
