The video terminal can be a fixed camera or a handheld mobile camera, and is linked with the maintenance arming task or the maintenance disarming task through cloud service to acquire images corresponding to arming points or disarming points. Because the mobile camera does not have a fixed position, the specific position of a defense deployment point in a shot image cannot be accurately identified, so that a position identification code needs to be set at the defense deployment point, for example, a two-dimensional code capable of identifying the position of secondary equipment is set at the defense deployment point, and the secondary equipment at the defense deployment point can be identified by including the position identification code in the shot image of the mobile camera. The process of image recognition by using the mobile camera is as follows: the method comprises the steps of obtaining an image of a field defense deployment point, identifying the position of field secondary equipment through a position identification code in the image, extracting an image of the secondary equipment at the corresponding position after defense deployment locking from a database, comparing the image with an image acquired on the field, and giving a defense deployment result of the secondary equipment at the corresponding position. If a fixed camera is adopted, because the position of each camera is fixed, the cameras can be numbered, and the numbers of the cameras and the secondary equipment of the defense deployment points at the positions of the cameras are bound, so that the image recognition system can confirm whether the secondary equipment of the defense deployment points is locked or not by collecting the images of the cameras corresponding to the defense deployment points. The process of image recognition by using a fixed camera is as follows: and acquiring images of the secondary equipment of each field defense deploying point, extracting the image of the secondary equipment at the corresponding position after defense deploying locking and comparing the image with the image acquired at the field, and giving a defense deploying result of the secondary equipment at the corresponding position.
Fig. 3 is a schematic flow chart of a third embodiment of the maintenance operation safety control method provided by the present invention. As shown in fig. 3, the present embodiment is different from the first embodiment of the maintenance work safety control method in that:
