[0023] Among them, the temperature sensor 105 is arranged inside the distribution cabinet, and its monitoring and collected data is transmitted to the microcontroller 103 through low-power or micro-power wireless communication. The humidity detector 106 is arranged outside the distribution cabinet for monitoring the environmental status of the distribution cabinet, and its monitoring and collected data is transmitted to the microcontroller 103 through optical fiber transmission. The mounting plate 107 is detachably connected to the shell 101 and is arranged on the top of the shell 101. The human-computer interaction panel 108 is electrically connected to the microcontroller 103 and is arranged on the protective door 102. The heat dissipation device is arranged on the side of the shell 101 close to the mounting plate 107. When the temperature sensor 105 is installed, it can be directly installed inside the corresponding distribution cabinet to detect the working temperature inside the distribution cabinet. The humidity detector 106 is directly installed on the distribution cabinet. In the working environment of the electric cabinet, and outside the power distribution cabinet, it is used to detect the ambient humidity in the working environment. A rectangular slide groove is arranged on the shell 101 to facilitate the installation of the mounting plate 107. After the mounting plate 107 is installed, its front end face abuts against the protective door 102 when the protective door 102 is closed and locked, thereby realizing limiting.
