In implementation, the detection device displays the overhaul instruction in front of the user through the AR, and when the user overhauls following the overhaul instruction, the detection device photographs the overhaul action of the user according to a preset time interval, where the preset time interval may be 1 second, and obtains an action image of the user, and the detection device obtains an action feature according to the action image, where the action feature may be a wrist, an arm, or the like. The detection equipment calculates the action image and compares the action image with the standard image according to the position of the action feature, namely, the position of the action feature in the action image is compared with the position of the action feature in the standard image, and the coincidence degree of the action feature is calculated. Check out test set compares contact ratio and threshold, and the threshold is that the producer presets, if contact ratio is not less than the threshold, then check out test set sends alarm signal, and alarm signal can be voice prompt, for example: if the action is wrong, please correct in time; and if the contact ratio is smaller than the threshold value, detecting that the equipment does not act.
The detection method and device based on the AR technology in the embodiment of the application have the implementation principle that: upon receiving a detection request from a user, the detection device issues a verbal prompt associated with the requested nameplate image.

The detection equipment searches for a corresponding equipment model in the nameplate database according to the equipment label, so that a corresponding troubleshooting instruction is searched for in the instruction database according to the equipment model, the detection equipment displays a first troubleshooting instruction through the AR glasses, then the detection equipment searches for and displays a corresponding failure confirmation template in the failure database, and a user inputs a failure information value on the failure confirmation template according to a detection result of the first troubleshooting instruction.
The detection equipment subtracts the fault information value from the equipment standard value to obtain a difference value, obtains an absolute value of the difference value to obtain an error value, and compares the error value with the error standard value to judge whether the fault information value is consistent with the equipment standard value. If the first troubleshooting instruction is consistent with the second troubleshooting instruction, the detection equipment displays the second troubleshooting instruction, if the first troubleshooting instruction is inconsistent with the second troubleshooting instruction, the detection equipment searches the corresponding maintenance instruction in the instruction database according to the first troubleshooting instruction, and the maintenance instruction is displayed through the AR glasses, so that a technician does not need to be sent to go to the site for maintenance, the time for maintenance of the faulty equipment is reduced, and the faulty equipment can be rapidly recovered to production.
