Distribution box with wireless passive temperature sensing device

Abstract

The invention provides a power distribution box with a wireless passive temperature sensing device. A temperature sensing device is installed on a distribution box body through a limiting mechanism. The limiting mechanism comprises a mounting plate, a swing arm and a second magnetic buckle. The temperature sensing device comprises a metal outer sheath, an RFID tag antenna and an RFID temperature measurement chip installed on the RFID tag antenna. A pull rod is mounted on the RFID tag antenna. The pull rod is detachably connected with the RFID tag antenna through a fixing bolt. The mounting plate is symmetrically installed relative to the center line of the metal outer protection shell, the hinge is installed on the mounting plate, the swing arm is installed on the hinge, the second magnetic buckle is installed on the side, close to the metal outer protection shell, of the swing arm, and the first magnetic buckle is arranged on the side, close to the second magnetic buckle, of the metalouter protection shell. The installation stability of the temperature sensing device can be effectively improved, and the temperature measurement accuracy is further improved.

Description

technical field [0001] The invention relates to a distribution box with a wireless passive temperature sensing device. Background technique [0002] RFID is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data information through radio frequency signals. The wireless passive temperature measurement problem in the distribution box, first of all, from the perspective of equipment installation, the structure inside the distribution box is complex , there are many metal parts, and the internal space is narrow, the conventional temperature measuring device cannot be successfully installed, and the installation stability of the temperature sensor in the distribution box in the prior art is poor, the accuracy of temperature detection is low, and it cannot meet the actual use Therefore, there is an urgent need to develop a distribution box with a wireless passive temperature sensing device to solve the problems...
