Problems solved by technology

However, there are some limitations to this approach: firstly, such sensors can be expensive (but prices have dropped significantly in recent years), and secondly, they are only useful for one function, namely to measure CO2 levels

Embodiment Construction

[0059] figure 1 A schematic diagram of a first embodiment of a device 1 according to the invention is shown. The device 1 includes: a signal input part 10, which is used to obtain one or more monitoring signals 20 of the monitored area; a respiratory monitor 11, which is used to determine the existence of One or more breathing parameters 21 of one or more subjects; and a CO2 estimation unit 12 for estimating the CO2 level 22 in the monitored area based on the determined one or more breathing parameters.

[0060] Device 1 may typically be implemented in hardware and / or software, eg as a processor, computer or application program ("app") running on a correspondingly programmed user device (eg a smartphone).

[0061] A primary application of the invention may be vehicles such as cars and buses. A car can be considered a restricted environment if its ventilation system controls the intake of fresh air (from the outside). Today's cars are equipped with ventilation systems that m...

Abstract

The present invention relates to a device, system and method for CO2 monitoring. To enable continuous monitoring at low cost and in a simple manner, the device comprises a signal input (10) for obtaining one or more monitoring signals (20) of a monitored area, a breathing monitor (11) for determining one or more breathing parameters (21) of one or more subjects present in the monitored area from the obtained one or more monitoring signals, and a CO2 estimation unit (12) for estimating the CO2 level (22) in the monitored area based on the determined one or more breathing parameters.

Description

technical field [0001] The present invention relates to devices, systems and methods for CO2 monitoring. Furthermore, the invention relates to a vehicle comprising such a device. Background technique [0002] Normal dry air at standard temperature and pressure (STP) of 101.325 kPa and 0° C. consists of 20.95% oxygen, 78.08% nitrogen, 0.0314% carbon dioxide, 0.93% argon and trace amounts of 14 other gases (expressed by volume). Assuming normal oxygen levels in the air, the following figures are typical for confined spaces with very limited airflow, such as underground mines: [0003] · Normal air is 0.03% or 300ppm CO2. [0004] • The time-weighted threshold limit for CO2 is 0.5% (or 5000ppm). [0005] • Headache and increased respiratory rate occurred at 10000 ppm (1%). [0006] • The short-term exposure limit is 30000 ppm (3%) and these amounts cause a doubling of the normal respiration rate. [0007] · Asthma and poisoning occur above 50000ppm (5%) [0008] • Loss of...
