Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The key of the fogging is that the temperature difference between the inner surface of the glass window of the camera and the temperature and humidity difference between the outer surface (environment) of the glass window is large, and when a certain difference value is exceeded, water vapor in the air inside the equipment is easy to fog when being close to the glass window with low temperature. Therefore, to prevent fogging, the defogging device should be activated when (or before) the temperature and humidity of the surface of the window reaches a critical value.

For the situation of fogging of a camera, the conventional method is to install a temperature and humidity sensor in the camera, package the temperature and humidity sensor in a patch manner, and weld the temperature and humidity sensor on a single plate to detect the temperature and humidity in a cavity, and then judge whether to open a defogging device according to detected temperature and humidity data. However, the single board can generate heat when working, the temperature and humidity sensor is welded on the single board, the detected temperature and humidity condition of the temperature rise of the single board superposed with the cavity environment of the camera is detected, and the actual detection value is inaccurate. The temperature measured by the temperature and humidity sensor is the temperature of the environment in the camera cavity (and is influenced by the heat generated by the work of the single plate), and is different from the temperature of the glass window; the humidity measured by the temperature and humidity sensor is the humidity near the single plate, and because the temperature near the single plate is influenced by heat generated by the work of the single plate, the change of the temperature can influence the humidity (the temperature is increased to increase the absolute water amount which can be accommodated in the air and lower the relative humidity test result), and further the humidity near the single plate is different from the humidity near the glass window, so that the humidity measured by the temperature and humidity sensor welded on the single plate is different from the humidity of the glass window.

The embodiment of the application provides a camera temperature and humidity detection structure, as shown in fig. 1, the camera includes a glass window 1 arranged on the shell, the camera temperature and humidity detection structure includes a single plate 2 arranged in the camera, a connecting cable 4 and a temperature and humidity sensor 3, the temperature and humidity sensor 3 is arranged on the glass window 1, and the temperature and humidity sensor 3 is electrically connected with the single plate 2 through the connecting cable 4.

In practice, a thermally conductive adhesive is applied to the side of the first end 41 facing the glass window 1, and then the first end 41 is bonded to the glass window 1. The heat conducting glue can support repair, namely, when the connecting cable 4 is detached for maintenance, the first end 41 of the connecting cable 4 can be conveniently taken down from the glass window 1, and repair and maintenance are facilitated.
