Centralized room gas detection system

Abstract

The invention discloses a centralized room gas detection system. Through a pipeline connected with a periodic cyclic gas extraction detection device and under the control of a control device, the periodic cyclic gas extraction detection device sequentially and cyclically extracts gases in each room into the periodic cyclic gas extraction detection device through electric exhaust fans for detection and then detects the concentration of the detected gases in each room. In such a way, the concentration of the detected gases in a plurality of rooms can be detected by only one or one group of gas detection probes, which reduces the number of the used gas detection probes and saves the one-time investment of mounting cost. Moreover, the gases in the rooms are extracted through the electric exhaust fans which can be arranged in a hidden way so as to keep the attractive appearance of the rooms. Simultaneously, the periodic cyclic gas extraction detection device can be arranged at any position outside the rooms so as to be convenient to mount and check. Finally, for the similar reasons in use, if the gas detection probes need replacing, only one or one group of gas detection probes is replaced, which greatly reduces use cost.

Description

technical field [0001] The invention relates to a room gas detection system, in particular to a centralized room gas detection system. Background technique [0002] In office buildings, conference rooms, classrooms, hotels, exhibition halls, hospitals, shopping malls, bars, restaurants, airports, railway stations, entertainment halls, theaters and other densely populated and relatively closed places, due to the large number of people, the concentration of carbon dioxide often occurs If the temperature is too high and hypoxia occurs, ventilation systems are usually installed in these places to supplement fresh air to each room (or different corners of the hall). However, based on the air conditioning of room temperature and the consideration of saving electric energy, the ventilation system is not always in working condition, and the ventilation system of each room needs to be intelligently managed, which requires a room gas detection system to detect the air in the room.

AI Technical Summary

Problems solved by technology

Therefore, each room is equipped with a gas detection probe, which requires high installation costs and a large investment.

[0008] 2. It affects the appearance and is inconvenient for maintenance

[0009] In order to achieve better detection results, the gas detection probe is installed outside the wall and protruded in the room, which affects the beauty of the room

In addition, when overhauling, it is necessary to go to each room for overhauling, which will affect the work

[0010] 3. High cost of use

Since gas detection is related to human safety, the detection effect of the gas detection probe will deteriorate after a period of use, such as 2 to 3 years, and it needs to be replaced. It is a waste of money to replace the gas detection probes in all rooms at once. Small expenditure, therefore, the use cost is quite high
