Generally, the temperature can reach 70-105 °C (bare copper wire). When it is not under load, it will rapidly cool down. After returning to room temperature (about 25°C), obvious differences can be observed through thermal infrared imaging, so the charged state can be judged by monitoring the temperature of each part (compared to normal temperature).
但红外成像会模糊设备细节，不利于操作人员作业，若工作时还需摘掉眼镜，则失去其便利快捷的优势，且容易因忘记佩戴而导致失去作用。鉴于以上考量，该***装置除了装设有热红外镜头外，还引入了AR技术，由热红外成像测绘实时温度判断其是否处于带电状态，若为带电状态则将带电体标记出来，相关标记通过DV-Hop定位算法计算投影在AR眼镜半透屏幕上，其位置为视野实景的对应位置，这样操作人员即可透过该AR屏幕观察到该部件的带电标识，起到警示作用，且又不会影响正常视野，从而使操作人员对现场设备导电状态做到一目了然。However, infrared imaging will blur the details of the equipment, which is not conducive to the operation of the operator. If the glasses need to be removed during work, the advantages of convenience and speed will be lost, and it is easy to lose their function due to forgetting to wear them. In view of the above considerations, in addition to being equipped with a thermal infrared lens, the system device also introduces AR technology to determine whether it is in a charged state by mapping the real-time temperature of thermal infrared imaging. The DV-Hop positioning algorithm is calculated and projected on the semi-transparent screen of the AR glasses, and its position is the corresponding position of the real scene of the field of view, so that the operator can observe the charged mark of the part through the AR screen, which plays a warning role, and does not It will affect the normal field of vision, so that the operator can see the conductive state of the field device at a glance.
进一步地，为标记准确，需要确保热红外镜头的视野与AR眼镜相同，当需要标记显示时，首先利用DV-Hop定位算法计算该标记在热红外图像所处位置，再将该标记显示在AR设备屏幕的相应位置，从而使操作人员看到的为被标记的物品，其效果示意图如2所示。Further, in order to mark accurate, it is necessary to ensure that the field of view of the thermal infrared lens is the same as that of the AR glasses. When the mark needs to be displayed, first use the DV-Hop positioning algorithm to calculate the position of the mark in the thermal infrared image, and then display the mark on the AR. The corresponding position of the device screen, so that the operator can see the marked item, and the schematic diagram of its effect is shown in Figure 2.
为避免受无效热源干扰，且提高判断的准确性，该***加入了视觉识别功能，会自动将视野内物品与***内置的站所带电设备图像进行对比，非相关设备不纳入判断，识别到内置图像相关物品，则会将当前温度与常规带电运行温度进行对比，二者接近或远高于室温则认为设备处于带电状态，若当前温度远高于正常带电运行温度，则可能为异常运行状态，如过负荷、异常放电等，此 时会特殊标出，以引起注意。In order to avoid the interference of invalid heat sources and improve the accuracy of judgment, the system has added a visual recognition function, which will automatically compare the objects in the field of view with the images of the live equipment built in the system, and the non-related equipment will not be included in the judgment. For image-related items, the current temperature will be compared with the normal live operating temperature. If the two are close to or much higher than room temperature, the device is considered to be in a live state. If the current temperature is much higher than the normal live operating temperature, it may be in an abnormal operating state. Such as overload, abnormal discharge, etc., will be specially marked at this time to attract attention.
