Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide gas concentration measurement technology, and in particular to a novel wireless carbon dioxide gas concentration measurement device. Background Technology

[0002] Accurate measurement of carbon dioxide concentration is crucial in various scientific research, industrial production, and daily life scenarios. In the field of biological culture, the growth and reproduction of cells and microorganisms are extremely sensitive to carbon dioxide concentration; concentration deviations can affect the culture results. During food storage, improper control of carbon dioxide concentration can easily lead to food spoilage. Traditional carbon dioxide concentration measuring devices are mostly single-parameter measurements that do not consider the interference of environmental factors such as temperature and humidity on the measurement results, resulting in large measurement errors. Some devices use wired connections, which are not only inconvenient to install in closed and sensitive environments such as carbon dioxide incubators, but also cause environmental interference, affecting measurement accuracy and environmental stability. In addition, the sensor positions of existing devices are fixed, making it difficult to adapt to complex scenarios with uneven gas distribution in different spaces, and they are difficult to maintain and have limited application range. Therefore, developing a carbon dioxide concentration measuring device that can accurately measure, wirelessly transmit, flexibly adapt, and is easy to maintain has become a problem that needs to be solved.

Compared with the traditional single measurement method, it greatly improves the measurement accuracy and ensures data reliability.

[0014] According to the novel wireless carbon dioxide gas concentration measuring device, a third connecting rod is threadedly connected to the top of the main body of the detection box near the right side, and a humidity sensor is provided at the upper end of the third connecting rod.

[0015] By adopting the above technical solution, the threaded connection facilitates the installation and debugging of the humidity sensor, enabling it to accurately measure the ambient humidity in a suitable location.

[0016] According to the novel wireless carbon dioxide gas concentration measuring device, a heat dissipation fin is provided at the right end of the cabin door, and a heat dissipation fin is provided at the rear end of the detection box body.

[0017] By adopting the above technical solution, the heat dissipation fins increase the heat dissipation area, accelerate the dissipation of heat generated during device operation, and prevent the internal components from overheating due to heat accumulation, which could affect the performance and lifespan of core components such as CMOS chips.

[0018] According to the novel wireless carbon dioxide gas concentration measuring device, the rear end of the battery compartment is wrapped with a heat insulation layer, which is located inside the main body of the detection box.

[0019] By adopting the above technical solution, the heat insulation layer can effectively block the heat generated by the battery from being transmitted to other components inside the testing box, thus preventing the battery heat from interfering with the normal operation of electronic components on the circuit board.

[0030] A battery compartment 13 is fixedly connected to the right side of the bottom inner wall of the main body 1 of the test box. A through hole 17 is provided at the right end of the battery compartment 13. The right end of the through hole 17 communicates with the outside of the main body 1 of the test box. The right end of the through hole 17 is tightly fitted with the hatch 10. The right end of the hatch 10 is hinged to the right surface of the main body 1 of the test box. A battery 15 is installed inside the battery compartment 13.

[0031] The front end of the cabinet door 2 is provided with a first connecting groove 12. The rear end of the first connecting groove 12 passes through the cabinet door 2 and communicates with the interior of the detection box body 1. The left side of the detection box body 1 is provided with a second connecting groove 16. The right side of the second connecting groove 16 extends into the interior of the detection box body 1. The second connecting groove 16 is located on the left side of the circuit board 20. The top of the detection box body 1 is threadedly connected to a first connecting rod 3 near the left side. A temperature sensor 4 is provided on the top of the first connecting rod 3. The top of the detection box body 1 is threadedly connected to a second connecting rod 5 near the center. A carbon dioxide sensor 6 is provided on the top of the second connecting rod 5.

[0032] The top of the main body 1 of the testing box is threaded with a third connecting rod 7 near the right side. A humidity sensor 8 is installed at the upper end of the third connecting rod 7. A heat dissipation fin 11 is installed at the right end of the chamber door 10. A heat dissipation fin 9 is installed at the rear end of the main body 1 of the testing box. The rear end of the battery compartment 13 is wrapped with a heat insulation layer 14, which is located inside the main body 1 of the testing box.

[0033] Working principle: The device collects raw signals of external environment temperature, CO2 concentration and humidity through temperature sensor 4, carbon dioxide sensor 6 and humidity sensor 8 on the top of the detection chamber body 1. These sensors extend out of the detection chamber through the first connecting rod 3, the second connecting rod 5 and the third connecting rod 7 to ensure direct contact with the measured environment such as a carbon dioxide incubator. At the same time, the threaded connection design allows for flexible adjustment of sensor height to adapt to different gas distribution scenarios. The first connecting groove 12 and the second connecting groove 16 of the detection chamber body 1 ensure gas flow, so that the sensors can accurately reflect the environmental conditions.

[0034] The analog signal collected by the sensor is transmitted to the circuit board 20 on the mounting bracket 18 on the inner wall of the main body 1 of the detection box via wires. The signal is amplified, filtered and preliminarily calibrated by the temperature standard 19, humidity standard 21 and carbon dioxide standard 22, and then sent to the CMOS chip 23.

[0035] The CMOS chip 23 incorporates a multivariate compensation algorithm to deeply analyze the interaction mechanisms of temperature changes leading to changes in gas density and humidity affecting sensor sensitivity. Based on a preset compensation model, it precisely corrects the raw data, eliminating environmental interference to improve measurement accuracy. The processed high-precision data is converted into a wireless signal by the data transmission module 24 at the bottom of the circuit board 20 and sent to an external terminal for non-contact real-time monitoring, avoiding interference from wired connections. The device is powered by battery 15 located in the battery compartment 13 on the right side of the bottom inner wall of the main body 1 of the detection box. The heat insulation layer 14 at the rear of the battery compartment 13 reduces the power consumption of battery 15. 5. The impact of heat generation on circuit components is investigated. Simultaneously, the heat dissipation fins 9 at the rear of the main body 1 and the heat dissipation fins 11 at the right end of the compartment door 10 are monitored to accelerate heat dissipation, ensuring that core components such as the CMOS chip 23 operate in a stable temperature environment. The hinged design of the main body door 2 and the compartment door 10 facilitates the maintenance of internal components and the replacement of the battery 15. The through hole 17 provides a channel for the battery compartment 13 to the outside and is sealed by the compartment door 10. The whole system achieves high-precision, low-interference, and long-term stable measurement of carbon dioxide concentration in complex environments through a collaborative process of multi-parameter acquisition, intelligent compensation, wireless transmission, and structural protection.
