Abstract

The invention discloses a passive wireless non-contact temperature measuring device, which comprises a shell body, a shell body cover, a PCB assembly, an electricity-taking assembly, a first infrared sensor, a second infrared sensor and a hoop, , wherein a groove is formed in the middle part of the shell body, the shell body cover is used for covering the shell body, the PCB assembly consists of two PCB which are vertically and fixedly installed, the first infrared sensor is installed on one PCB of the PCB assembly, the second infrared sensor is installed on the other PCB of the PCB assembly, the electricity-taking assembly comprises an electricity-taking bracket and an electricity-taking coil, a first fixed through hole is formed in each of the left and right sides of the shell body, an empty cavity is formed in the electricity-taking bracket, and the hoop passes through the first fixed through holes and the empty cavity of the electricity-taking bracket to form a closed magnetic circuit. The passive wireless non-contact temperature measuring device adopts the non-contact type double infrared sensors for irradiation, irradiates different places in X and Y axial directions, is suitable for equipment in a complex environment, and greatly improves the reliability through multi-point monitoring.

Description

technical field [0001] The invention belongs to the field of temperature measuring sensors, in particular to a passive wireless non-contact temperature measuring device. Background technique [0002] Traditional temperature measurement methods, such as wires, cannot meet the conditions of closed environment and high voltage and high current. Electrical equipment in operation works in a high voltage and high current state, and certain defects in the equipment will cause the abnormal temperature rise of the equipment components. It will cause a vicious circle between temperature and contact resistance value, which may eventually lead to safety accidents such as equipment burning and explosion. [0003] The wireless temperature sensor is usually composed of four parts: lithium battery, micro control unit, temperature sensor, and wireless module, and works in an all-digital mode. It is installed on high-voltage equipment and equipotentially measures equipment temperature. The...
