Embodiment

[0037] The utility model relates to a multi-point aiming regional abnormal gas detection device. The outer reflection mirror of the detection device is installed on the wall inside the medicine storage warehouse, and is used for detecting the change of medicinal materials in the medicine storage warehouse.

[0038] Such as figure 1As shown, the detection device includes an external reflector 1 and a reference reflector 4. There are several external reflectors 1 scattered in the space to be detected for gas detection. The housing of the reference reflector 4 is installed on the rotating mechanism Above, the rotating mechanism drives the reference reflector 4 to rotate to detect the gas in the corresponding area of ​​each outer reflector 1 respectively. The reference reflector 4 is provided with an emission window 10 and a reception window 6, and the emission light 2 is emitted from the emission window 10, and is reflected by the external reflector 1 to become the reception ligh...

Abstract

The invention relates to a multi-point aiming regional abnormal gas detection device. The device comprises an outer reflector and a reference reflector, wherein the reference reflector comprises a shell, and a light emitter, a modulator for controlling the light emitter, a detection assembly and an inner reflector which are arranged in the shell, the inner reflector is mounted on the shell througha rotating shaft, and the rotating shaft drives the inner reflector to rotate to enable the detection device to be switched between a detection state and an internal reference state; when the detection device is in the internal reference state, emitted light emitted by the light emitter reaches the detection assembly through the internal reflector; when the detection device is in the detection state, emitted light emitted by the light emitter reaches the outer reflector through an emitting window in the shell, is reflected back to the reference reflector through the outer reflector, and enters the detection assembly through the receiving window in the shell. Compared with the prior art, the device is advantaged in that the device is simple in structure, excellent in performance, high in detection speed, easy to operate, large in measurable range, high in accuracy and the like.

Description

technical field [0001] The invention relates to an infrared detection device, in particular to a multi-point aiming regional abnormal gas detection device. Background technique [0002] Traditional Chinese medicine is an indispensable part of traditional Chinese medicine culture in our country. It is a medicine that can be directly used in clinical practice after a series of processing such as processing and preparation under the guidance of the theory of traditional Chinese medicine. With the continuous improvement of the national economic level, the clinical application of traditional Chinese medicine is becoming more and more common, and people have higher requirements for the quality of traditional Chinese medicine. Therefore, the search for Chinese medicine with "both high quality and high quality" has become a hot topic at present. [0003] As we all know, there are many types of traditional Chinese medicines, a wide range of sources, and complex ingredients. During th...
