Embodiment Construction

[0022] In order to be able to understand the technical content of the present invention more clearly, the following embodiments are specifically described in detail.

[0023] Such as Figure 1~4 Shown is an embodiment of an optical gas detector provided by the present invention, where, as figure 2 As shown, the optical gas detector of the present invention includes a light pipe path 10, two optical distributors 8, 9 respectively arranged at both ends of the light pipe path, and calculations that are respectively connected to the optical distributors. Unit 7, that is, the end of the light pipe path is provided with an optical distributor.

[0024] Such as figure 1 As shown, the optical distributor has a splitter 6, a first sensor 4, a second sensor 5, three light sources 1, 2, and 3. The light source 1 emits light E1 of a specific preset wavelength, and the light source 2 emits a specific preset wavelength. Set wavelength of light E2, light source 3 emits light E3 of specific prese...

Abstract

The present invention relates to an optical gas detector, comprising a light pipe, two optical splitters arranged at both ends of the light pipe, and computing units respectively connected to the optical splitters, each The optical splitter has a splitter, a first sensor, a second sensor, and at least two light sources, and the splitter is configured to split the total optical path formed by the at least two light sources of each optical splitter, so that the total light path passing through the splitter The optical path includes a first optical path and a second optical path, the first optical path is transmitted to another optical splitter through the light pipe, and the second optical path enters the second sensor, so that the second sensor is configured to detect the first optical path. The light intensity of the two optical paths, the first sensor is set to receive and detect the light intensity of the first optical path from another optical splitter, according to the light intensity detected by the first sensor and the second sensor in the two optical splitters, The calculation unit calculates and judges whether there is gas leakage.

Description

Technical field [0001] The invention relates to the technical field of gas detectors, and relates to an optical gas detector. Background technique [0002] Gas leaks often occur, and the cost of gas leaks is very expensive. Point-type gas detectors are commonly used in industry to protect potential gas leakage areas. However, if the wind blows in the opposite direction, the point gas detector will not be able to detect it. To cover a larger area, open path gas detectors are often used. Most open path gas detectors work as a pair of optical transmitter and optical receiver. A pair of open path gas detectors need to be placed in direct locations with obstacles. Cloudy, fog or smoke will disable open path gas detectors. The other inconvenience of the open path gas detector is that it can only work in a straight line. And, it must not have any obstacles between the transmitter and the receiver. In order to cover a 1km (1000m) gas pipeline, 50 point gas detectors need to be ins...
