It should be noted that, when the humidity data information in the cabinet body 1 is greater than the preset humidity data information, the humidity data information in the cabinet body 1 is dynamically regulated and controlled by the damping protection mechanism 2; in this embodiment, by starting the blower, a preset type of gas (such as sulfur hexafluoride gas) inside the cabinet body can enter through the first pipeline, after being dried, the gas flows into the cabinet body again from the second pipeline to complete the adjustment of humidity, the service life of the inflatable cabinet is prolonged, control valves (not shown) are arranged in the first pipeline and the second pipeline, when humidity data is detected to be higher than a preset humidity threshold value, the control valves are opened, the gas in the cabinet body 1 can flow out from the first pipeline, and finally flows in after being dried from the second pipeline, so that intelligent control is realized. When the gas needing to be dried enters into the third pipeline through the first pipeline, the through holes of the side plates arranged in the third pipeline enter into the cylindrical barrel, the rotary blades arranged at the first notch of the third pipeline can drive the rotary blades due to the action of the gas, so that the rotary shaft can rotate, the cylindrical barrel can be driven to rotate, the dry particles in the cylindrical barrel can rotate, the wet gas can fully contact with the dry particles, due to the rotating effect of the particles, the contact area of the dry particles and the wet gas is enlarged, and more than one area contacts, so that the drying effect in the drying process is improved.
In addition, the method can further comprise the following steps:
acquiring geographic position information of an inflatable cabinet in a target area, constructing a layout diagram of the inflatable cabinet according to the geographic position information of the inflatable cabinet in the target area, and acquiring the quantity information of the inflatable cabinets in the layout diagram of the inflatable cabinet;
constructing an internet of things monitoring network according to the quantity information of the inflatable cabinets in the layout of the inflatable cabinets, and acquiring humidity data information in each inflatable cabinet within preset time through the internet of things monitoring network;
presetting outlier threshold information, introducing a local outlier detection algorithm, calculating an outlier of humidity data information in the air-filled cabinet through the local outlier detection algorithm, and judging whether the outlier is larger than the outlier threshold information or not;
and when the outlier is larger than the outlier threshold information, taking the humidity data information corresponding to the outlier larger than the outlier threshold as abnormal data, and eliminating the abnormal data.
It should be noted that, because abnormal data may exist in the collected data, such as data with negative humidity or data with large jitter occurring within a preset time, the data is only data which happens accidentally but not data with humidity data information larger than humidity threshold information, and the abnormal data can be further screened out by the method, so that the collected data is real data, and the humidity monitoring of the air charging cabinet is more reasonable.
The method for constructing the internet of things monitoring network according to the quantity information of the inflatable cabinets in the layout diagram of the inflatable cabinets specifically comprises the following steps:
acquiring the quantity information of the total monitoring sensors according to the quantity information of the inflatable cabinets in the layout of the inflatable cabinets, initializing the quantity information of communication facilities of the current Internet of things monitoring network, and constructing an information transmission network according to the quantity information of the communication facilities of the current Internet of things monitoring network;
inputting the quantity information of the total monitoring sensors into the information transmission network for calculation to obtain information transmission rate information, and presetting an information transmission rate threshold;
introducing a genetic algorithm, setting a genetic algebra based on the genetic algorithm, and when the information transmission rate information is smaller than an information transmission rate threshold value, uniformly increasing the quantity information of the communication facilities of the current Internet of things monitoring network according to the genetic algebra to perform iterative calculation on the information transmission rate information;
when the information transmission rate information is not smaller than the information transmission rate threshold, outputting the quantity information of the communication facilities of the current Internet of things monitoring network, constructing an information transmission network according to the quantity information of the communication facilities of the current Internet of things monitoring network, and constructing an Internet of things monitoring network according to the information transmission network and the quantity information of the total monitoring sensors.
It should be noted that, the monitoring network of the internet of things is a communication network integrating an information transmitting base station and an information receiving base station, so that data acquired by the monitoring sensors are transmitted to a computer terminal, different numbers of communication facilities (the information transmitting base station and the information receiving base station) can cause different MIMO networks, as the number of the monitoring sensors increases, different information transmission rates of the monitoring sensors can be different, iterative computation can be performed on the number information of the communication facilities of the monitoring network of the current internet of things through a genetic algorithm, whether the current monitoring network accords with an information transmission rate threshold value is judged, when the current monitoring network does not accord with the information transmission rate threshold value, genetic iteration is performed, so that when the sensors collect information and transmit the information to the terminal, the data are collected by the control terminal in time, the air charging cabinet can be controlled in time according to actual data, and the response speed is better than that of the prior art.
In summary, the humidity data in the air inflation cabinet is regulated and controlled according to the humidity data by the set moisture regain protection mechanism, so that the humidity value in the air inflation cabinet accords with the preset humidity threshold value, and the service life of the air inflation cabinet is prolonged; on the other hand, the cylindrical barrel can rotate under the action of gas by arranging the rotary vanes, so that the dry particles in the cylindrical barrel can turn over, the gas can be fully contacted with the dry particles, and the drying effect is improved. In still another aspect, the method and the device for the gas filling of the gas filling cabinet improve the service life of the gas filling cabinet by detecting the concentration information of the preset type gas in the gas filling cabinet, and supplementing the gas to the gas filling cabinet when the concentration information of the preset type gas in the gas filling cabinet is lower than the preset concentration.
