Temperature and humidity regulation function is realized by following principle: adopt and first regulate humidity, rear adjustment temperature manner.By the air themperature in the first Temperature Humidity Sensor T1 detection cultural relic exhibition district and humidity, by the unlatching that controls the first triple valve YV1 by contaminated air by air inlet after circulation air pump enters cleaning system and has purified, open the 3rd three-way magnetic valve YV3, the warm and humid angle value T2 after purification is detected by the second Temperature Humidity Sensor T2, open the 4th three-way magnetic valve YV4 simultaneously, when humidity value is greater than setting value, then enter except moist chamber dehumidifying, when humidity value is less than setting value, then enter water tank, enter and add wet process, processed laggard enter except moist chamber, detect dehumidifying indoor humidity parameter T4, meet setting value, enter temperature controlled compartment, heated by heater, detected temperatures parameter T3, open magnetic valve SV1, aspiration pump P2, temperature detect switch (TDS) WK1, by the gas suction cultural relic exhibition sound zone system after purification-constant temperature and humidity.
Cleaning system self-cleaning function is realized by following principle: by clicking " automatically cleaning " button on liquid crystal touch screen, send blowback instruction, carry out reverse blow with clean nitrogen to cleaning system in purge gas collection place to clean, realize the automatically cleaning of cleaning system.During blowback, open blowback and flow to switch and adapter, close working air current and pressure-fired air-flow simultaneously.
Constant temperature and humidity system alarm point: when liquid-level switch in water tank (switching value) action being detected, sends the low warning of liquid level, shows on a liquid crystal display.When Temperature Humidity Sensor T3 signal being detected, reach that temperature is high, humidity is high, temperature is low, humidity low setting value time, close aspiration pump P2 immediately, cut off the abnormal gas of humiture and enter.
Cultural relics in the collection of cultural institution showcase LED luminance and illumination.Select high-purity adjustable illumination technology, the ultraviolet that strict control light source produces and infrared light affect the deterioration of historical relic, by illuminance transducer intelligent control illumination, minimal illumination should not be less than 0.8 with the ratio of average illumination, but for being highly greater than the plane showpiece of 1.4 meters, then require that minimal illumination should not be less than 0.4 with the ratio of average illumination.Only have the showroom of general illumination, ground minimal illumination should not be less than 0.7 with the ratio of average illumination.According to human body sensor monitoring, in good time automatic regulating lightness.
What the utility model mainly solved is cultural relics display case Problems existing in historical relic's protection, bandwagon effect, Intellectualized monitoring etc.; propose to cover showcase Material selec-tion, multi-security design, low noise low-power consumption humid control and the design of high-purity tunable light source, wireless networking communication, historical relic open up the cultural relics in the collection of cultural institution showcase that old intellectuality, burglar alarm etc. are integrated; while guarantee historical relic safety; improve historical relic exhibition dis environment, effectively protect historical relic.The utility model well solves the problems referred to above, cultural relics in the collection of cultural institution showcase, except meeting basic application function, also achieves self-purging function, automatic humidifying function, automatic temperature-adjusting adjusting function, anti-theft alarm function, LED luminance automatic regulation function, local parameter arranges several large functions such as function, standard interface and expanded function.Cultural relics in the collection of cultural institution showcase more can meet Modern Museum cultural relics in the collection of cultural institution theory.Cultural relics in the collection of cultural institution showcase can introduce WIA-PA 2.4GHz wireless communication mode, to the centralized management such as LED illumination System, purification-constant temperature and humidity machine, guard against theft and alarm system, wireless networking mode of showcase, and the available protecting exhibition dis environment of historical relic.
