Abstract
Description
Technical Field
[0001] This utility model relates to the field of greenhouse gas monitoring technology, specifically a greenhouse gas characteristic monitoring device. Background Technology
[0002] Greenhouse gas monitoring refers to the monitoring of the main gases that produce the greenhouse effect in the ambient air inside a greenhouse.
[0003] Greenhouses easily produce common greenhouse gases such as carbon dioxide (CO2) and methane (CH4). The purpose of greenhouse gas monitoring is to understand greenhouse gas emissions and assess the concentration of harmful gases. By monitoring greenhouse gas emissions, adjustments can be made to ventilation or other growing environments to meet crop needs. Furthermore, gases harmful to workers, such as methane, can pose a threat if they reach certain concentrations, necessitating monitoring and early warning. However, traditional gas monitoring devices are simply installed in a fixed location. Harmful gases, such as methane, tend to accumulate locally. It's common for harmful gases to be below safe levels at the sensor's location, but exceed safe levels just one or two meters away. Therefore, traditional sensors do not consider the flow of gases within the greenhouse, resulting in a limited monitoring range. Moreover, traditional monitoring sensors do not store the monitored data, making it inconvenient for workers to query data on various gases within the greenhouse.
[0004] Therefore, to address this issue, a greenhouse gas characterization monitoring device is needed that can monitor gases within a large area of greenhouses. Utility Model Content
[0005] The purpose of this invention is to provide a greenhouse gas characteristic monitoring device. This invention utilizes louvered vents with gas detection sensors installed within them. A built-in fan generates negative pressure, allowing gases from various directions to flow into the louvers and contact the gas detection sensors for detection. The air flowing past the sensors exits through an exhaust duct, significantly expanding the monitoring area and eliminating blind spots. When abnormal data is detected, an audible and visual warning system alerts staff to the gas anomaly in the area. The detected data is then transmitted wirelessly to a server at the monitoring end for data storage. Staff can easily access the data via smart terminals to adjust indoor indicators according to crop needs. The device is simple, convenient, quick, and highly efficient; this invention is highly practical.
[0006] This utility model is implemented as follows:
[0007] A greenhouse gas characteristic monitoring device includes a housing, a display screen fixedly mounted on one side of the housing, control buttons mounted on one side of the display screen, a wireless transmission unit mounted on the side of the housing adjacent to the control buttons, an audible and visual warning device mounted adjacent to the wireless transmission unit, a louvered vent device fixedly mounted on the side wall of the housing adjacent to the wireless transmission unit, a gas detection sensor fixedly mounted inside the louvered vent device, a fan fixedly embedded in the housing at the inner end of the gas detection sensor, and an air outlet pipe sealed to the fan, the outlet of the air outlet pipe penetrating the housing.
[0008] A control processing unit is fixedly installed at the bottom inner part of the housing. The display screen, the sound and light warning device, the fan and the wireless transmission unit are all connected to the output end of the control processing unit, and the gas detection sensor and the control buttons are all connected to the input end of the control processing unit.
[0009] The control processing unit is connected to a monitoring terminal via a wireless transmission unit. The monitoring terminal includes a server connected to the wireless transmission unit, and the server is connected to a PC and a smart terminal via a wireless connection.
[0010] Furthermore, the control processing unit adopts an STM32 control processing unit, the wireless transmission unit adopts a Wi-Fi unit, and the gas detection sensor adopts a GW-3000B gas detection sensor.
[0011] The smart terminal is a smartphone or tablet computer, and there is at least one smart terminal. This allows staff to easily connect to the server for data acquisition and querying via the smart terminal; the operation is simple, convenient, fast, efficient, and saves time and effort.
[0012] Furthermore, the housing has a cover plate rotatably mounted on the top of the side wall on the side where the fan is located.
[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting up louvered air vents and installing gas detection sensors inside the louvers, and then generating negative pressure through a built-in fan, the gas in the greenhouse can flow into the louvers from all directions, come into contact with the gas detection sensors for detection, and then flow out through the air outlet pipe. This greatly expands the monitoring area of the monitoring device and avoids blind spots. When the data is abnormal, an audible and visual warning device will be used to alert staff to the gas anomaly in the area. The detected data is then transmitted to the monitoring server via a wireless data transmission unit for data storage. Staff can easily connect to the server via smart terminals to retrieve the data and adjust indoor indicators according to the next needs of the crops. The operation is simple, convenient, fast, and efficient; this utility model is highly practical. Attached Figure Description
