2. Limitations of detection technology: the current air detection technology is commonly used to install fixed or semi-fixed gas detectors. However, the number of gas detectors and the types of sensors cannot be very large and dense, and the method is very limited in terms of technical detection depth, detection range, detection accuracy and the like, cost and speed. The underground space has the problems of long-distance quick, effective, multi-point and detection technology and a long-distance effective alarm mode, and cannot completely meet the actual application requirements.
3. Complexity of data processing: the data volume obtained by air detection is large and complex, and timely data processing, analysis and alarm are needed to determine the remote and multi-point composition and concentration distribution conditions of the air. The complexity, timeliness and precision of data processing also increase the detection difficulty.
4. Safety risk consideration: air detection may involve the detection of toxic and harmful gases, and therefore a series of safety measures are required to ensure the safety of the detection personnel and the surrounding environment. Particularly in the form of alarm signals, need to be quickly transmitted to each relevant person.
5. The detection of the existing gas alarms, often giving an alarm on the host body or single point. The personnel receiving the early warning signal are few (mainly at both ends). When a gas accident occurs in a complex terrain, the warning is often not known for the first time at a far place, a noisy place or a corner. At present, the single-point alarm mode is not effective and wide enough.
How to solve the above technical problems is an object to be studied by those skilled in the art.
