Problems solved by technology
These wireless transmission technologies have the following disadvantages: 1) The frequency is high, the penetration ability is poor, and the actual transmission distance is relatively short when data transmission is performed between the confined space and the external space. Unstable, or even completely unable to communicate; 2) High power consumption, high cost for users to use

The invention discloses a gas content detection method and system. The method comprises the steps that a gas content detection device is adopted to detect gas content data in an environment space in real time; a first data acquisition device is adopted to acquire or receive, store and forward the gas content data primarily; a second data acquisition device is adopted to secondarily receive and forward the gas content data subjected to primary forwarding or the gas content data subjected to primary storage; and a PC is adopted to receive the gas content data subjected to secondary forwarding ata third time, wherein the gas content detection device and the first data acquisition device achieve direct communication in a first mode, the first data acquisition device and the second data acquisition device achieve direct communication in a second mode, the second data acquisition device and the PC achieve direct communication in a third mode, and the second mode is LORA. According to the technical scheme, the transmission distance when data transmission is achieved between a closed space and an external space is greatly increased, and the power consumption is low.
Description
technical field [0001] The invention relates to the field of environmental gas detection, in particular to a gas content detection method and system. Background technique [0002] Effective detection of gas content in various environments such as indoor residential or office environments, industrial production environments, and even urban or rural atmospheric environments is an important means to ensure people's normal working and living environments. [0003] Many technical solutions capable of detecting gas content have been researched, which are used to detect the content of various gases in different environments, and further display or perform statistical analysis. [0004] For example, when detecting gas in a confined space (for example, inside a refrigerator), it may not be possible to transmit the collected gas data to the outside of the confined space in a wired transmission manner. Therefore, some technical solutions use the gas content sensor arranged in the conf...
