Problems solved by technology

This brings inconvenience to the navigation survey: on the one hand, the weather conditions at sea are changeable, especially at night, the rainfall information cannot be obtained in time, which affects the collection of samples; When the sea conditions are bad, it will also bring hidden dangers to the personal safety of the sampling personnel
In addition, the working status of the atmospheric sampler used in the prior art cannot be displayed remotely. In order to avoid factors such as instrument failure affecting sample collection, sampling personnel need to go to the top deck to check the working status of the instrument regularly.

Embodiment 1

[0046] Such as figure 1 shown.

[0047] An atmospheric sampler automatic control system for navigational measurement, comprising a rain-sensing module, a ship start-stop sensing module and an atmospheric sampler respectively connected to a controller; the atmospheric sampler is connected to the controller through a relay. The rain sensing module controls the automatic closing of the atmospheric sampler during rainfall and the automatic opening after the rain ends. The ship start and stop sensing module controls the automatic closing of the atmospheric sampler when the ship is stopped and the automatic opening after the ship starts. The atmospheric sampler performs atmospheric sampling under the control of the controller.

Embodiment 2

[0049] Such as image 3 shown.

[0050] As described in embodiment 1, the automatic control system of the atmospheric sampler used for navigation measurement, the difference is that the controller is an MSP430F149 controller (the schematic diagram of the circuit structure of the atmospheric sampler is as follows Figure 9 shown).

Embodiment 3

[0052] The atmospheric sampler automatic control system that is used for navigation measurement as described in embodiment 2, difference is, MSP430F149 controller is connected with HEADER-7X2POL Jtag download module, 32768Hz crystal oscillator circuit and reset circuit (as image 3 , Figure 6 shown). The functions of the above three modules respectively realize the writing and downloading of the controller program, and provide the clock signal and reset function for the controller.

Abstract

The invention relates to an automatic control system of an air sampler for underway measurement and an application of the automatic control system. The automatic control system of the air sampler for underway measurement comprises a rain sensing module connected with a controller, a ship starting-stopping induction module and an air sampler respectively. By adopting the automatic control system of the air sampler for underway measurement, the air sampler can be automatically started and stopped in the case of raining and ship stopping, information such as time, position and the like in the automatic starting and stopping processes can be completely recorded, and the labor cost is effectively saved while the monitoring requirement is met.

Description

technical field [0001] The invention relates to an automatic control system of an atmospheric sampler used for navigation measurement and its application, and belongs to the technical field of marine atmospheric monitoring. Background technique [0002] As the main channel for land-based pollutants to enter the ocean and as the main bridge for land-sea interaction, the marine atmospheric environment has become one of the main contents of global environmental change research, and the development of related monitoring technologies has also played an extremely important role in the research process. effect. According to the existing marine atmospheric monitoring technical regulations, the marine atmospheric monitoring project mainly includes suspended particulate matter measurement and precipitation measurement, and the sample collection work of the suspended particulate matter project is jointly completed by the atmospheric sampler and the sampling filter membrane.
