Description

Technical Field

[0001] The utility model relates to the technical field of laser methane remote sensing, in particular to a vehicle-mounted top-mounted laser methane remote sensing device. Background Art

[0002] The working principle of the vehicle-mounted laser methane telemetry device is that the laser beam is emitted by the transmitter, focused and guided to the target area through the optical lens and reflector. When the laser beam passes through the area containing methane gas, part of the laser will be absorbed by the methane molecules and the frequency will change. The receiver receives the laser signal after passing through the methane gas and converts it into an electrical signal and sends it to the data processing unit. The data processing unit analyzes the received signal and calculates the concentration of methane gas based on the pre-calibrated model.

[0003] Existing vehicle-mounted laser methane telemeters are mostly fixed to the vehicle body by bolts through a roof fixing bracket when installed. However, during actual installation, personnel are required to hold the vehicle-mounted laser methane telemeter so that the mounting holes are aligned for bolt fixing. This can easily cause accidental touches to cause the vehicle-mounted laser methane telemeter to shift, affecting installation efficiency. Utility Model Content
