Granary comprehensive gas online detection system

Abstract

The invention provides a granary comprehensive gas online detection system. The detection system comprises a gas selector, a monitoring pipe network and a monitoring host. The gas selector is a multi-channel gas selection concentrator, is arranged in a granary, is used for sucking gas in the granary, and can reduce the number of unnecessary gas pipelines in the granary and save the construction cost. The monitoring pipe network comprises gas sensors, the gas sensors are used for monitoring parameters of gas, and the monitoring pipe network is used for leading out the gas in the granary. The monitoring host is electrically connected with the gas sensors and used for monitoring and analyzing the gas led out by the monitoring pipe network. According to the invention, a plurality of gas sensors are integrated on one monitoring host, comprehensive calculation is carried out according to the parameters of all the gas sensors, data is more accurate, multiple parameters of the gas are monitored at the same time, monitored data information is more timely and effective, and the interior of the granary can be correspondingly adjusted according to results obtained through calculation.

Description

technical field [0001] The invention belongs to the technical field of granary information construction and management, and in particular relates to a granary comprehensive gas online detection system. Background technique [0002] With the rapid development of sensor technology, communication technology, automation and intelligence, some equipment related to gas monitoring has appeared for the monitoring of grain conditions in grain storage, such as detecting nitrogen (N 2 ) concentration, oxygen (O 2 ) concentration, the total phosphine (PH 3 ) concentration, carbon dioxide (CO 2 ) concentration, read the gas concentration online in real time, and transmit it to the monitoring service center through the communication bus, which is convenient for people to grasp the warehouse environment information in real time and dynamically. [0003] However, in the actual use process, different sensor probes are distributed in various positions in the warehouse. To detect different ...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual use process, different sensor probes are distributed in various positions in the warehouse. To detect different gas concentrations, independent gas pipelines are required to drain to different sensor probes, which undoubtedly increases construction costs and wastes warehouse space. At the same time, it also increases the difficulty of construction. In addition, each individual gas sensor works independently. Only when the detected data information is transmitted to the monitoring server can the data information in the environment be integrated, which will affect the data transmission in terms of data integration. Cause a certain delay, resulting in inaccurate monitored data information
