Background of the programme

China has a long history, all parts of the country are stored high-value important archival materials, for the safety of archival materials, the place where the archives are stored must maintain suitable temperature, humidity and good ventilation conditions. Temperature, humidity and air quality are two important factors affecting the quality of archival preservation, usually the standard temperature should be maintained at 18°C-24°C, and the humidity should be controlled between 45%-65%. At the same time, the archives storage place should avoid direct sunlight and ultraviolet radiation to prevent the archives from fading and aging. The abnormal temperature and humidity of the long-term storage environment will not only lead to the fading of the handwriting and the distortion of the paper materials, but also the serious consequences of material aging and paper corrosion. Timely control of the temperature and humidity in the archives warehouse and the regulation of the air quality in the archives can effectively protect and prolong the life of archives, and are also the key to protecting the health of archives staff.

Implement functionality

According to the >> of the <<Archives Law of the People's Republic of China amended and promulgated in June 2020, the construction of the National Archives shall meet the requirements of practicality, safety, science, beauty, environmental protection and conservation. In order to ensure the safety of archival documents, the archives must be kept away from flammable, explosive, and pollution sources, and the inside of the archives must follow the following "ten prevention" standards:

Schematic design

The design of the environmental monitoring system of Zonghengtong Archives refers to the "ten prevention" requirements of the archives, and is equipped with various high-precision sensors to collect various environmental parameters in the archives in real time, and interconnects with various sensors and intelligent devices in the archives through the environmental monitoring and alarm host independently developed by Zonghengtong, so as to realize the real-time monitoring and abnormal alarm of various environmental parameters and equipment operation status in the archives, and the system topology is as follows:

Introduction to system functions

In order to ensure the safe, complete and sustainable storage of archives, the environmental monitoring system of Zonghengtong Archives provides the following main "ten" functions to ensure the safe operation and maintenance of archives based on the special requirements of archives, as follows:

1. Electricity safety monitoring: real-time monitoring of the mains power supply status of the archives, and immediate alarm if the power supply is abnormal;

2. Temperature and humidity monitoring and control: collect the temperature and humidity data in the archive warehouse, upload the data to the monitoring platform in real time, if the abnormal temperature and humidity of the environment is detected, the system will immediately send an alarm prompt, and at the same time, according to the settings, it can automatically link the precision air conditioner, humidifier, dehumidifier and other equipment to start the automatic adjustment function;

3. Air quality monitoring and control: real-time collection of various harmful gas concentrations in the archive room, immediate alarm output if abnormalities are found, and operation such as ventilation treatment is carried out in conjunction with the fresh air system;

4. Light intensity monitoring and light control: real-time monitoring of indoor light intensity and ultraviolet intensity in archives, and lighting control can be linked to lighting or curtains to automatically control the light source;

5. Water leakage monitoring and control: real-time monitoring of the leakage situation in the archives, when there is a water leakage, quickly locate the leakage location and immediately notify the alarm, and at the same time can link the operation of closing the water valve;

6. Anti-intrusion monitoring: realize infrared intrusion alarm, for illegal intruders, it can drive sound and light alarm and linkage video camera to capture and other operations;

7. Fire safety monitoring: docking with the fire protection system and realizing the linkage function, when there is a fire, the system automatically alarms, and can also realize fire linkage;

8. Video surveillance: video screen monitoring of multiple areas in the archives;

9. Access control system: realize the access management of all personnel in the archives, and connect with the access control system to ensure access security;

10. Large-screen visualization: 3D modeling of the archives, and the simulation system is directly projected on the monitoring screen.

Features & Benefits:

At the same time, the design and software of the system strictly follow the requirements for the preservation of cultural relics in the archives and the industry standards for the collection of cultural relics "Requirements for the Application of Monitoring Terminals for the Environmental Monitoring System for the Preservation of Cultural Relics in the Collection", "Requirements for the Network Communication Application of the Environmental Monitoring System for the Preservation of Cultural Relics in the Collection", etc., and the environmental monitoring system of the archives has the following advantages:

1. Interface customization: According to the needs of customers, the full customization function of login and operation interface can be realized, and the language switching function can be supported.

2. System flexibility: The system can run Windows, Unix (Linux) and domestic operating systems (and domestic databases);

3. System comprehensiveness: The system comprehensively covers the monitoring functions of the archives, such as power supply and distribution monitoring, environmental monitoring, fire protection, access control and video system;

4. Safe, reliable and scalable: The system adopts high-performance equipment and high-precision sensors, and adopts a real-time alarm system that is safe and reliable, and can expand the functional modules according to the specific needs of the archives to fully meet the integrated monitoring requirements of the archives.
