System and method for remotely measuring and automatically calibrating tail gas of inland ship

Abstract

The invention discloses an inland ship tail gas telemetering automatic calibration system and method, and the system comprises a ship tail gas laser telemetering unit which is used for collecting ship tail gas data in real time, and monitoring the tail gas component concentration of an on-board ship in real time; the gas cylinder module unit is used for storing standard gas required by calibration; the data collecting and processing unit is used for remotely controlling calibration and calibration of the ship tail gas laser telemetering unit according to ship tail gas data collected in real time; the network communication unit is used for data transmission between the data processing unit and the intelligent control unit; the intelligent control unit is used for remotely and automatically controlling communication between the gas cylinder module unit and the ship tail gas laser telemetering unit according to the automatic calibration instruction. According to the invention, the operation and maintenance personnel can remotely and automatically calibrate the equipment through the network, compared with manual calibration, the work task load of the operation and maintenance personnel can be reduced, meanwhile, errors caused by human factors are avoided, parameters are automatically adjusted by using an intelligent algorithm, and the monitoring precision of the instrument can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of ship exhaust remote measurement, and in particular relates to an automatic calibration system and method for inland river ship tail gas remote measurement. Background technique [0002] With the rapid development of the economy, the number of ships in my country's inland rivers is also increasing, and ship exhaust is also one of the important sources of pollution affecting cities along the river. In order to win the tough battle against pollution, the government has successively issued policies on the emission of air pollutants. The focus is on how to effectively monitor the elemental composition of air pollution in ship exhaust, so the development of ship exhaust monitoring technology is an inevitable trend. Most of the traditional methods use oil samples for detection, which have problems such as high blindness, high cost, and low efficiency. The intelligent remote sensing monitoring method can be use...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at regular calibration of the tail gas laser telemetry equipment of inland river ships in long-term operation to ensure the precision and accuracy of the monitoring results. Generally, the ship lock management office of the inland river basin is built for the tail gas laser telemetry system of inland river ships, which is far from the office of the maritime supervision department. The location is also far away, and there are certain limitations in manual calibration, and there are errors in detection, which affect the accuracy of monitoring results. In order to solve the above problems, an automatic calibration system and method for inland river ship exhaust telemetry are proposed.
