Ozone sonde based on gas-sensitive semiconductor and monitoring method

Abstract

The invention discloses an ozone sonde based on a gas-sensitive semiconductor and a monitoring method, and relates to the field of ozone monitoring. The ozone sonde comprises a sounding carrier, a first memory, an environment sensor, a logic controller and at least one ozone sensor are carried on the sounding carrier, and the logic controller is connected with the sounding carrier, the first memory, the environment sensor and each ozone sensor. The ozone sonde is suitable for ozone monitoring of the near space, the ozone content in the environment can be conveniently and rapidly obtained, ozone monitoring can be achieved on a sounding instrument, and the requirement of the instrument for long-term in-situ ozone measurement in the low-temperature and low-pressure environment of the near space can be met.

Description

technical field [0001] The invention relates to the field of ozone monitoring, in particular to an ozone sonde based on a gas-sensitive semiconductor and a monitoring method. Background technique [0002] At present, the in-situ measurement of commonly used ozone is usually based on ultraviolet photometry and electrochemical methods. The ultraviolet photometry is observed by a special laboratory observation instrument, which is usually fixed in the laboratory for ambient ozone observation, and the air is pumped from the outside to the instrument for measurement by an air pump. Law. [0003] However, the electrochemical method requires an electrolytic cell, and the space of the electrolytic cell is limited, which determines that this method cannot be used for long-term measurement. Generally, it is only used for one-time vertical profile measurement of ozone, and the duration is generally not more than 2 hours. The solution is obviously affected by temperature, and it is ea...

[0003] However, the electrochemical method requires an electrolytic cell, and the space of the electrolytic cell is limited, which determines that this method cannot be used for long-term measurement. Generally, it is only used for one-time vertical profile measurement of ozone, and the duration is generally not more than 2 hours. The solution is obviously affected by temperature, and it is easy to condense at low temperature. Therefore, it is difficult for this method to complete the long-term high-altitude odor in-situ oxygen monitoring task.
