The current position information of the inspection equipment can be obtained by installing a related positioning device on the inspection equipment, the specific positioning device can be a GPS locator or a Beidou positioning device, and can also be other positioning devices, and the planning mode of the shortest route passing through all the positions of the key equipment to be inspected is the same as the description part of the step S200, and is not repeated here.
And S2c0, if the reason information is abnormal condition information of the operation parameters of the key equipment, planning the shortest route from the inspection equipment to the position of the key equipment to be inspected according to the current position information of the inspection equipment, the current position information of the key equipment and the preset moving speed of the inspection equipment, and predicting and analyzing the predicted time node for completing the detection of the operation parameters of the key equipment to be inspected.
The preset moving speed of the inspection equipment can be obtained by inquiring from a preset database in which the moving speed of the inspection equipment is stored, and the prediction of the node of the predicted time for detecting the operation parameters of the key equipment to be inspected is obtained as follows: firstly, obtaining a departure time node of the inspection equipment, then calculating the ratio of the shortest route to the moving speed, namely specific consumed time, and finally analyzing and calculating the estimated time node of the inspection equipment for completing the key equipment to be inspected according to the departure time node and the specific consumed time of the inspection equipment.
For example, assuming that the departure time node of the inspection equipment is 10 points, the shortest route is 500 meters, and the moving speed is 2 meters/second, the specific time consumption is 250 seconds, that is, the estimated time node is 10 points, 4 minutes and 10 seconds.

For example, assuming that the next time of the polling device is 10 points and 10 minutes, the estimated time of completing the detection of the operation parameters of the key device to be polled is 10 points, 4 minutes and 10 seconds, and the time difference is 5 minutes and 20 seconds.
And step S2e0, judging whether the analyzed and acquired time difference is within a preset time difference. If yes, go to step S2f 0; if not, step S2g0 is executed.
Wherein the preset time difference is obtained by inquiring from a preset database storing the time difference.

The implementation principle of the embodiment is as follows:
the method includes the steps that starting of inspection equipment is comprehensively considered to have different reason information, and an inspection route is planned according to inspection tasks corresponding to the different reason information, wherein the starting reason is especially considered to be the condition information that abnormal operation parameters of key equipment appear, once the key equipment with problems in operation parameters appears, if the time is close to the next planned inspection time of the inspection equipment, the inspection equipment is arranged to finish inspection of the remaining key equipment to be inspected at one time, and therefore the inspection plan planned by the next inspection time planning information is reduced.
In step S2c0 shown in fig. 2, because there is not necessarily only one key device to be inspected, but when there are a plurality of key devices to be inspected, the planned route manner will also be different, which will also affect the rationality of the predicted time node for completing the detection of the operation parameters of the key devices, and in order to further ensure the accuracy and rationality of the predicted time node for completing the detection of the operation parameters of the key devices, a further prediction analysis needs to be performed on the predicted time node for completing the detection of the operation parameters of the key devices, which is specifically described in detail with the embodiment shown in fig. 3.

And S2c3, arranging the inspection sequence of the key equipment to be inspected with the corresponding risk level according to the risk level arrangement sequence from high to low.
For example, assuming that there are two key devices, wherein the risk level of one key device is 1.1, and the risk level of the other key device is 1.2, the key devices with the risk level of 1.2 are inspected first, and then the key devices with the risk level of 1.1 are inspected.
And S2c4, planning the shortest route which finishes the inspection one by one according to the inspection sequence arrangement by taking the current position of the inspection equipment as the starting position.
And S2c5, analyzing and calculating the total moving time of the inspection equipment according to the planned path length of the shortest route for completing inspection and the preset moving speed of the inspection equipment, and analyzing and calculating the time node for completing inspection of the inspection equipment according to the time node for starting the inspection equipment and the total moving time of the inspection equipment, wherein the time node is used as a predicted time node for completing the detection of the operation parameters of the key equipment.
Wherein, the analysis of the total removal consuming time of equipment of patrolling and examining obtains as follows: and taking the ratio of the path length of the planned shortest route which finishes the inspection to the preset moving speed of the inspection equipment as the total moving time of the inspection equipment.

another is a question b, with a 70% proportion, where the question a corresponds to the critical device's own level 2 risk and the question b corresponds to the critical device's own level 1.5 risk, then the formula that affects the risk level of itself is as follows: y =0.3 × 2+1.5 × 0.7=1.65, so the risk level affecting the own device is a level 1.65 risk level.
