Problems solved by technology

[0005] The natural gas leakage monitoring scheme uses a single monitoring device, which has a small monitoring area and large loopholes, and cannot realize the leakage monitoring of the entire natural gas station; multiple monitoring devices can perform multi-point and multi-line monitoring, but the consumption of accessories is large and the data processing is complicated

Embodiment 1

[0031] Such as Figure 1-3 As shown, the natural gas leakage monitoring system of this embodiment includes a laser gas remote measurement device, a lifting pole, a laser gas remote measurement instrument 15 , a guide rail 16 and a server terminal 20 .

[0032] Among them, the laser gas remote measurement device is a scanning remote sensing monitoring instrument, and the laser gas remote measuring instrument is an open remote sensing monitoring instrument, both of which adopt the advanced TDLAS measurement principle, which can realize remote sensing measurement of gas concentration under an open optical path.

[0033] The lift-type vertical pole is installed at a suitable target position in the process area of ​​the natural gas station, and the laser gas remote measurement device is installed on the top of the lift-type vertical pole. The laser gas remote measurement device cruises according to the preset position to realize "line monitoring".

[0034] The guide rail 16 is arra...

Embodiment 2

[0050] The natural gas leakage monitoring system of this embodiment differs from Embodiment 1 in that:

[0051] Omit the setting of the server terminal and its communication connection, and adopt the monitoring scheme of the scanning laser gas remote measuring device and the open laser gas remote measuring instrument respectively by adopting the lifting pole and the guide rail, the number of monitoring equipment is small, and the difficulty of data processing is small. It can realize the measurement of the leakage point of the whole natural gas station.

[0052] For other system architectures, reference may be made to Embodiment 1.

Embodiment 3

[0054] The natural gas leakage monitoring system of this embodiment differs from Embodiment 1 in that:

[0055] Through the laser gas remote measurement device and the laser gas remote measurement instrument, the detection signal is directly transmitted wirelessly to the server terminal, omitting the setting of the explosion-proof control box and its related components, and simplifying the system structure.

[0056] For other system architectures and monitoring methods, reference may be made to Embodiment 1.

Abstract

The invention belongs to the technical field of natural gas leakage monitoring, and particularly relates to a natural gas leakage monitoring system and monitoring method. The natural gas leakage monitoring system comprises a laser gas telemetering device, a lifting type vertical rod, a laser gas telemeter and a guide rail, the lifting type vertical rod is arranged at the target position of a natural gas station process area, and the laser gas telemetering device is installed on the lifting type vertical rod; the guide rail is arranged on one side of the natural gas station process area, and the laser gas telemetering device is movably matched on the guide rail so as to move back and forth along one side of the natural gas station process area. Space monitoring of natural gas leakage of thenatural gas field station is achieved through the laser gas remote measuring device and the laser gas remote measuring instrument. The monitoring scheme that the lifting type vertical rod and the guide rail carry the scanning type laser gas remote measuring device and the open type laser gas remote measuring instrument respectively is adopted, the number of monitoring devices is small, the data processing difficulty is small, and measurement of leakage points of the whole natural gas station can be achieved.

Description

technical field [0001] The invention belongs to the technical field of natural gas leakage monitoring, and in particular relates to a natural gas leakage monitoring system and a monitoring method. Background technique [0002] For natural gas in unmanned natural gas stations (CH 4 ) leakage, the traditional manual regular inspection method is mainly adopted, and the detection methods mainly include human ears to identify the sound of the leakage point, spraying soapy water, and hand-held portable detectors. However, the traditional manual regular inspection cannot quickly and accurately judge the location information of the leakage point, and it is difficult and inefficient, which can easily cause great safety hazards. [0003] Especially for the high gas concentration, flammable and explosive industrial environment of natural gas stations, traditional manual regular inspections are not suitable. At present, infrared and ultrasonic monitoring equipment are widely used, but ...
