Anti-interference infrared temperature detector

Abstract

The invention belongs to the field of temperature detection equipment, and particularly relates to an anti-interference infrared temperature detector. The anti-interference infrared temperature detector comprises a fixed base, a functional top plate and a motor, and is characterized in that uniformly arranged supporting columns are fixedly connected to the side surface, which is close to the fixedbase, of the upper surface of the fixed base; the number of the supporting columns is four; the upper end faces of the four supporting columns are jointly and fixedly connected with the same functional top plate; a through hole penetrating up and down is formed in the surface of the functional top plate; and a motor is fixedly connected to the right side surface, which is close to the lower surface of the functional top plate, of the functional top plate. According to the invention, air sealing and local air purification of a local detection area above a detected object are effectively realized, the total air purification amount is greatly reduced, the working efficiency of measurement is improved, and the weak signal obtained by detection does not need to be processed by a circuit with high magnification times and a processing chip with a specific algorithm, so that the information processing is greatly reduced.

Description

Technical field[0001]The invention belongs to the field of temperature detection equipment, and specifically is an anti-interference infrared temperature detector.Background technique[0002]The infrared temperature detector uses the infrared energy emitted by the detected object. When the temperature of the detected object is hotter, its molecules are more active, and the infrared energy it emits is higher. The optical equipment inside the infrared temperature detector can Collect the infrared energy radiated by the object and concentrate the energy on the infrared sensor. Then the infrared sensor converts the energy into electrical signals, which are amplified and displayed as temperature readings.[0003]According to CN102564600A, a metal detector that detects the infrared light emitted by the workpiece within a certain detection range, and processes the weak signal obtained by the detection by a circuit with high magnification and a processing chip with a specific algorithm. In a wo...

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, first, the infrared temperature detector can only measure the temperature of the surface of the object to be measured, but cannot measure the temperature inside the object; second, steam, dust, etc. will block the instrument. The optical system will affect the temperature measurement. In order to reduce the influence of steam, dust and other substances on the measurement, the existing solution is to first compress the air, remove the particles and dust in the air, and then wipe it with a rag, but this method, every time The total amount of air that needs to be compressed is high, and the air purification time is long, and the energy consumption is high. At the same time, the instrument is manually wiped every time, which increases the workload of the workers and reduces the measurement efficiency; third, the existing invention In this method, by detecting the infrared light emitted by the measured object within a certain detection range, the detected weak signal is processed by a circuit with a high magnification and a processing chip with a specific algorithm. Or in the working environment of smoke, etc., the infrared signal of the unique band emitted by the measured workpiece is converted into a digital signal that the host computer or the main control device can accept, thus realizing the working environment with high concentration of water vapor, dust or smoke, etc. For the detection of hot metals, on the one hand, the measurement technology and equipment requirements are relatively high; Temperature detector
