Temperature and humidity control method of archive warehouse_temperature and humidity recorder
The temperature and humidity in the warehouse are closely related to the preservation of the archives. Improper temperature and humidity will affect the preservation time of the archives and affect the preservation of the archives. In order to make the temperature and humidity of the archives warehouse meet the requirements of file storage, certain measures need to be taken to control and adjust the temperature and humidity of the archives warehouse.

In the actual situation, due to the differences in climate and environment in different regions, the temperature and humidity control of the archive warehouse needs to be combined with the local situation. After a large number of actual warehouse temperature and humidity basic monitoring, statistics and analysis are carried out. Finally, a more reasonable temperature and humidity control standard was determined.

my country’s file protection regulations stipulate that the normal standard temperature and humidity of the file warehouse is 12℃~24℃, and the relative humidity is 45%~60%. In order to meet the requirements, the file management workers must check and record the temperature and humidity of the warehouse every day, and then adjust the temperature and humidity.

The temperature and humidity control method of the archive warehouse

First of all, it is necessary to ensure that the temperature and humidity of the archive warehouse are scientifically and reasonably controlled, and the temperature and humidity recorder is used to accurately record the temperature and humidity changes in the warehouse, and establish and improve the regulations related to the management of the archive warehouse. system. At the same time, management personnel must have relevant professional knowledge.

According to the natural climate conditions in different seasons, the temperature and humidity control of the archives warehouses are also different.

Generally speaking, the temperature and humidity of the archives warehouses in the spring and autumn of the year can basically meet the temperature and humidity management of my country's archives. Basic regulations and requirements. However, during the summer from June to September, due to the high temperature of the external environment, the temperature of the archive warehouse will also increase. Therefore, it is necessary to do a good job of drying and cooling during this period. At the same time, there is a lot of rain during this period. Measures such as airtightness, temperature reduction and humidity reduction can be adopted, and air-conditioning, dehumidifier, fan and other equipment can be comprehensively used. If necessary, desiccant and medicine can be used to dehumidify. During the winter, it is necessary to control the ventilation in the archive warehouse. The ventilation time is around 14:00, preferably within 2 hours. When the temperature outside the warehouse is higher than about 4 degrees inside the warehouse, the ventilation temperature can achieve a certain effect.

Do a good job in the sealing of warehouse facilities, and at the same time strengthen the control of personnel entry and exit

In spring and winter, the temperature and humidity difference becomes greater. On the one hand, it is necessary to conduct airtight protection of archives and various objects themselves. Increase the level of airtight protection for various storage cabinets, file cabinets and other facilities. On the other hand, it is necessary to strengthen the management of warehouse access, reduce the frequency of opening the warehouse, and reduce the number of personnel entering and exiting.

Long-term real-time monitoring and analysis

In the same day, the relative change range of outdoor shows regular fluctuations over time. Specific adjustments can be made according to the analysis situation. If the test data is not scientifically analyzed, these data will lose their meaning. Therefore, the data in the warehouse must be analyzed scientifically and effectively to obtain the law of temperature and humidity changes in the warehouse, and then adjust them correctly.

For the different floors of the archive warehouse, there are also differences in the control of temperature and humidity.

In the specific work of archives preservation and management, it is necessary to reduce the cost as much as possible according to the existing building settings and equipment conditions. Reduce energy consumption. The ventilation will be wet to avoid large changes in the temperature in the warehouse.

The developed radio temperature and humidity recorder adopts a measuring unit imported from Switzerland. It has a unique internal frequency hopping technology with high measurement accuracy. It can monitor the temperature and humidity in the archive warehouse in real time, and has strong communication anti-interference ability.

The temperature and humidity recorder has built-in 260,000 records and uses a rechargeable lithium battery. It can be used continuously for more than 45 days on a single charge, and it can also be used for long-term power supply. The device also has a power-off resumable transmission function. If the communication is disconnected, the data will be automatically cached, and the historical data will be retransmitted to the server after the communication is restored; the built-in buzzer will send an alarm message as soon as the temperature and humidity values u200bu200bexceed the limit. ; The device can also be equipped with a wireless environment monitoring host to realize simultaneous monitoring of up to 32 areas.

The radio temperature and humidity recorder monitors the temperature and humidity of each measuring point, and transmits the data to the wireless environment monitoring host through 433 wireless transmission, and then the small host will The data is uploaded to the cloud platform, and the administrator can remotely monitor the device through the mobile terminal of the cloud platform.

Transfer data through 433 wireless, without wiring indoors, and will not damage the documents in the archive; the device can record temperature and humidity data in real time, support curve view data, support TXT, Excel, PDF, etc. Export in various forms;

The factors affecting the archives include temperature and humidity, as well as water and fire. Therefore, smoke alarms, jamming water immersion transmitters, and sound and light alarms can also be installed in the archives. Once an alarm occurs, the equipment will trigger an alarm so that measures can be taken immediately to avoid major losses.

Through rigorous and scientific control methods, we can ensure that the warehouse has the right temperature and humidity to minimize the damage to the documents and extend the life of the documents.
