Problems solved by technology
[0004] In order to avoid the shortcomings of the above-mentioned prior art, the present invention provides a cascading control method for the micro-environmental humidity of large-scale museum showcases, in order to control the work of multiple small constant humidity machines through accurate measurement and control algorithms, and overcome the problems of large-scale museum showcases. Humidity cannot be accurately judged, humidity control is unreasonable, and humidity distribution is uneven, and it can meet the humidity control needs of large showcases of different shapes and sizes

The invention discloses a museum large-scale showcase microenvironment humidity cascade control method, which is characterized by dividing a showcase into an upper-layer cultural relic display zone and a lower-layer device zone through a lower platform, wherein the cultural relic display zone is provided with a display stand for placing cultural relics, and the device zone is provided with a plurality of constant-humidity machines, which are provided with constant-humidity machine humidity sensors respectively; calculating a weight coefficient of each constant-humidity machine humidity sensorby utilizing a space humidity sensor, and obtaining an integrated humidity value of the cultural relic display zone through calculation; according to the difference value between the integrated humidity value and a set target humidity value, carrying out calculation by utilizing an incremental PID control algorithm to obtain humidity basic control quantity of each constant-humidity machine; and carrying out calculating to obtain control quantity of each constant-humidity machine according to the humidity basic control quantity. The cascade control method can accurately judge the humidity in each large-scale showcase in a museum, and reasonably adjust and control the humidity in each large-scale showcase in the museum, thereby improving the situation of uneven distribution of humidity, andmeeting moisture control requirements of different shapes and sizes of large-scale showcases.
Description
technical field [0001] The invention relates to the technical field of micro-environmental humidity control of museum showcases, in particular to a cascade control method for micro-environmental humidity of large-scale museum showcases. Background technique [0002] In the preservation of cultural relics in museums, humidity is an important factor. Different cultural relics require different humidity environments. At present, there are some humidity control capabilities in the market at 3m 3 The left and right small constant humidity machines can detect and adjust the humidity in the cultural relics display cabinet, so that the cultural relics in the small display cabinet can obtain a suitable humidity environment. However, for volume V≥10m 3 For large showcases, on the one hand, the use of a small constant humidity machine has limited control ability, and the humidity in the large showcase cannot quickly reach the target value; on the other hand, for a small constant humid...
