Description

Information transmission system for gas monitoring device

This case is about the monitoring environment application of a gas monitoring device, especially the information transmission system of a gas monitoring device.

At present, human beings pay more and more attention to the monitoring of ambient air quality in life, such as the monitoring of carbon monoxide, carbon dioxide, volatile organic compounds (Volatile Organic Compound, VOC), PM2.5, etc. in the ambient air. When exposed to these gases, it will Causes adverse health effects on the human body, serious and even life-threatening. Therefore, environmental air quality monitoring has attracted the attention of various countries. How to implement environmental air quality monitoring is a topic that urgently needs to be paid attention to.

It is feasible to use sensors to monitor ambient gas. If monitoring information can be provided in real time to warn people in a dangerous environment, it can be prevented or escaped in real time to avoid the impact on human health caused by exposure to the gas in the environment. For damage, it is a very good application to monitor the surrounding environment through sensors.

Of course, using sensors to monitor the environment can provide users with more information about the user’s environment, but the best performance for monitoring sensitivity and accuracy needs to be considered. For example, sensors rely solely on the natural fluid in the environment. The drainage of circulation not only cannot obtain a stable and consistent fluid flow for stable monitoring, but the drainage of natural fluid circulation in the environment takes a long time to reach the monitoring reaction of the contact sensor, which will affect the effectiveness of real-time monitoring.

In addition, although there are large-scale environmental monitoring base stations for ambient air quality monitoring, the monitoring results can only monitor the ambient air quality in a large area, and cannot effectively and accurately monitor the air quality in the close environment where humans are located. For example, indoor The air quality and the air quality around you cannot be effectively and quickly monitored. Therefore, if the sensor can be combined with a portable electronic device for application, it can achieve real-time monitoring anytime and anywhere, and can send the monitoring data to a place in real time. The cloud database performs data construction and integration to provide more accurate and real-time air quality monitoring information to activate the air quality notification mechanism and air quality processing mechanism.

In view of this, how to solve the monitoring accuracy of the sensor and speed up the monitoring response of the sensor, real-time monitoring anytime and anywhere, real-time transmission of monitoring data to the cloud database for data construction and integration, and provide more accurate and timely air quality Monitoring information to activate the air quality notification mechanism and the air quality handling mechanism is a problem that needs to be solved urgently.

The main purpose of this case is to provide an information transmission system for gas monitoring devices, which uses IoT communication modules to send monitoring output data to a cloud database device for data construction and integration, and to activate the information transmission system through multiple connected devices The air quality notification mechanism and the air quality processing mechanism achieve the effect of real-time display of information and notification.

To achieve the above objective, a broader implementation aspect of this case is to provide an information transmission system for a gas monitoring device, including: at least one gas sensing module, including at least one gas actuator, at least one gas sensor, and the gas actuation The control gas is introduced into the gas sensor module and monitored by the gas sensor to generate monitoring data; a microprocessor controller controls and starts the operation of the gas actuator, and performs calculation processing on the monitoring data of the gas sensor , To convert it into an output data information; and an IoT communication module to receive the output The data information is transmitted and sent to a networked relay station, and the output data information is transmitted to a cloud data processing device for storage through the networked relay station.

At the same time, the resonance plate 172 is synchronously displaced downwards under the influence of the resonance principle, which in turn increases the volume of the confluence chamber 171c, and due to the confluence chamber The air in 171c enters the chamber space 176, resulting in a negative pressure in the confluence chamber 171c, and the air is sucked into the confluence chamber 171c through the bus hole 171b and the air inlet 171a; please refer to page 5E again In the figure, the piezoelectric element 173d drives the suspension plate 173a to move upward, compressing the chamber space 176, and forcing the air in the chamber space 176 to transmit downward through the gap 173e to achieve the effect of air transmission. At the same time, The resonance plate 172 is also displaced upward by the suspension plate 173a due to resonance, and simultaneously pushes the gas in the confluence chamber 171c to move to the chamber space 176; finally, please refer to Figure 5F, when the suspension plate 173a is driven downward, the resonance plate 172 is also driven to move downward at the same time. At this time, the resonant sheet 172 will move the gas in the compression chamber space 176 to at least one gap 173e, and increase the volume in the confluence chamber 171c, so that the gas can continue to pass through. The gas holes 171a and the bus hole 171b converge in the confluence chamber 171c. By continuously repeating the above steps, the gas pump 17 can continuously enter the gas from the gas inlet hole 171a, and then transmit the gas downward through at least one gap 173e. The gas from outside the gas detection device is continuously drawn in to provide gas for the gas sensor 12 to sense, thereby improving the sensing efficiency.

At this time, the air jet orifice plate 181 will be driven together by the principle of Helmholtz resonance, so that the actuating body 183 will move upward. The upward displacement of 183 increases the volume of the airflow chamber 187, and its internal air pressure forms a negative pressure. The air outside the blower box gas pump 18 will be caused by the pressure gradient between the plurality of connecting pieces 181a of the jet orifice sheet 181 and the side wall. The air gap enters the air flow chamber 187 and collects pressure; finally, referring to Figure 6C, the gas continuously enters the air flow chamber 187, so that the air pressure in the air flow chamber 187 forms a positive pressure. At this time, the actuating body 183 is subjected to voltage Drive downwards to compress the volume of the airflow chamber 187 and push the gas in the airflow chamber 187 to cause the conductive gas to circulate, and the gas sensor 12 monitors the passing gas.
