Abstract

The invention discloses a photoacoustic spectrometry oil and gas monitoring system. The system comprises at least two oil gas monitoring units, and each oil gas monitoring unit is connected with a communication circuit; the communication circuit is connected with a backboard connector; adjacent backboard connectors are connected with each other; any one of the backboard connectors is connected with a server; according to the system disclosed in the invention, the plurality of oil and gas monitoring units are separately connected with one communication circuit; the communication circuit is connected with one backboard connector, the backboard connectors are connected with one another, signals of the oil and gas monitoring units can intersect with one another and then are sent to the server,monitored signals are integrated, and therefore monitoring of various substances is achieved; practicability of the photoacoustic spectrometry oil and gas monitoring system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a photoacoustic spectrum oil and gas monitoring system. Background technique [0002] The existing oil and gas monitoring system mainly places substances in airtight containers. The substances will be excited after absorbing light of a specific wavelength, and the excited substances will return to the initial state through radiative transition or non-radiative transition. This process will generate heat. ; If the wavelength of the absorbed light changes periodically, the pressure fluctuations in the container are also periodic; since the frequency of the modulated light is generally in the audio frequency range, the pressure fluctuations become sound waves; and then sensed by the acoustic sensor The electrical signal obtained by synchronously amplifying the acoustic signal perceived by the acoustic sensor is an optical signal. If the photoacoustic signal is recorded as a functi...
