Embodiment

[0054] like Figure 1 ~ Figure 4 As shown, the granary insect air and water detection unit with self-protection function includes a central processing unit, a power management module, a MODBUS module, a 485 communication module, an EMC protection module, pest traps a1~a32, sampling solenoid valves b1~b32, channels Strobe, multi-way E1, three-way E2~E5, gas circuit solenoid valve D1~D3, main air pump, auxiliary air pump, detection element, throttle valve, filter valve and return air pipe.

[0055] In this embodiment, the pest traps a1~a2, sampling solenoid valves b1~b32, channel selector and multi-channel E1 work together to realize point-selected sampling and fixed-point sampling.

[0056] In this embodiment, the pest detection gas path, the phosphine detection gas path and the protective detection gas path are formed through the joint action of the gas path solenoid valve and the pump. Among them, the gas path for pest detection starts from the outlet of multi-way E1 and end...

Abstract

The invention discloses a barn worm gas and water detection unit with a self protection function. The barn worm gas and water detection unit comprises a control circuit board, a gas collection device,an air path control device, a detection element, an electromagnetic valve control circuit and a pump control circuit. The goal of counting pest attraction density, shooting pest images, and detectingthe phosphoretted hydrogen concentration, carbon dioxide concentration, oxygen concentration and grain pile moisture content of the grain pile can be realized through extracting insect samples and gas samples in a grain pile. The invention also discloses a detection method of the barn worm gas and water detection unit with the self protection function. During the application, the detection flow process can be conveniently controlled; the damage to an oxygen sensor, a carbon dioxide sensor and a temperature and humidity sensor by phosphoretted hydrogen gas can be prevented; the requirements ofthe intelligent warehouse storage can also be met.

Description

technical field [0001] The invention relates to grain situation detection technology, in particular to a granary insect air and water detection unit and a detection method with self-protection function. Background technique [0002] Since 2015, the State Grain Administration has passed documents such as "Guiding Opinions on Vigorously Promoting the Development of Grain Informatization", "Guidelines for the Construction of Grain and Oil Storage Informatization (Trial)", "Opinions of the State Grain Administration on Regulating the Construction of Grain Industry Informatization" to speed up Digital, informatization, and intelligent construction of grain depots, comprehensive monitoring of the quantity, quality, and storage safety of grain and oil reserves, and promotion of technological innovation in scientific grain preservation. [0003] Traditional grain detection is limited to the detection of grain temperature and humidity, and a few manufacturers have extended the detect...
