Method for controlling internal air environment of museum case

Abstract

The invention provides a method for controlling an internal air environment of a museum case. The method for controlling the internal air environment of the museum case comprises the following steps of (a) detecting environment parameters in the museum case; (b) comparing a detected environment parameter to a preset standard range; and (c) starting an internal air environment control device to process the detected environment parameter if the detected environment parameter exceeds the standard range until the environment parameter conforms to the standard range. Requirements on environment purification and temperature and humidity adjustment of the closed museum case can be met, and the temperature, humidity and air pressure control precision can be smaller than or equal to 2%. The reliability and the stability are quite high, the openness and the expansibility are also quite high, the method is suitable for monitoring various precious relic exhibition and storage environments, and different environment parameters are adjusted according to demands of different relics; the size is small, the power consumption is low, and the method is suitable for purifying museum cases with different sizes and adjusting the humidity of the museum cases with the different sizes; water can be supplied for the museum case automatically, the temperature, the humidity and the air pressure can be adjusted, and air can be purified; monitoring information of the museum case can be transmitted to a remote monitoring room through wireless communication and can be monitored in a centralized manner; and functions of user management are fulfilled, and the safety of application of the control device is improved.

Description

technical field [0001] The invention relates to the field of automation, in particular to a method for controlling the internal air environment of a display case for cultural relics. Background technique [0002] There are tens of thousands of museums around the world with hundreds of millions of cultural relics in their collections. In my country alone, there are nearly 4,000 museums, with more than 30 million cultural relics in their collections, and hundreds of millions of cultural relics in private collections. Due to the long-term impact of environmental fluctuations and human factors, coupled with the fragility and aging of some cultural relics, the corrosion loss of cultural relics is very serious. According to statistics, 50.66% of the cultural relics in my country's collections have different degrees of corrosion damage, of which more than 2 million cultural relics (accounting for 16.5%) are severely corroded. The corrosion rate was the highest at 48.68%, followed ...

Problems solved by technology

With central air-conditioning, due to the large space of the museum, the temperature and humidity can only be set uniformly, and the humidity environment required by different types of cultural relics is not consistent, so it is difficult to accurately control the humidity of the storage micro-environment of each cultural relic

The control range of the passive humidity control agent is narrow, and there is a large lag in the sudden change. During this period, the cultural relics may be greatly damaged. For large-scale display cabinets and storage cabinets, only passive humidity control agents are used to control the humidity. Sex is not strong

The mechanical humidity control method usually includes mechanical components such as compressors and fans. Due to the rotating parts in the mechanical device, it is accompanied by noise during operation, and there is a possibility of oil leakage, which is easy to cause pollution, consumes a lot of power, and is prone to failure. It will have an adverse impact on the museum's cultural relics exhibition and storage environment, and at the same time it cannot achieve remote monitoring and unattended monitoring of the multi-parameter monitoring system for the preservation of cultural relics in the museum

At the same time, almost all humidity adjustment equipment needs to be replenished with water, with a short cycle and a large amount of maintenance

The central air conditioner and mechanical humidity control equipment commonly used at present have a certain air purification effect, but they have the following disadvantages: (1) The space in the museum is large, and the central air conditioner and mechanical humidity control equipment are placed in fixed locations, which cannot be achieved. Taking into account the purification effect; (2) Central air conditioners and mechanical humidity control equipment are usually large in size and weight, difficult to disassemble, clean, and replace, and require professional staff to operate. At the same time, toxic and harmful raw materials may be used in the manufacturing process of equipment components, which is easy to Secondary pollution; (3) The central air-conditioning and mechanical humidity control equipment currently on the market have not been specifically improved for the polluted gases and harmful microorganisms in the micro-environment of cultural relics, which directly leads to low purification efficiency; (4 ) Power consumption is large, which is not conducive to energy conservation and environmental protection; (5) Centralized control, automatic management measures and network technology are generally not adopted, and the optimization of cultural relics management cannot be achieved
