Purpose:
The seed low-temperature standard library, also known as the seed low-temperature storage library or seed storage library, is a professional equipment that can store seeds for a long time. This device adopts the principle of low temperature, which can keep the seeds with their original characteristics even after ten or even decades.
In order to explore and collect seeds of various crop varieties, scientifically store them, and ensure that the germplasm still has its original genetic characteristics and high germination rate after more than ten or even decades, it is of great significance for variety improvement, cultivation of high-yield, high-quality, and stress resistant new varieties, and providing rich seeds and research materials for theoretical research in biology.
The storage environment (mainly referring to temperature and humidity) has a significant impact on the lifespan of seeds. According to the different temperature and humidity environments inside the storage facility, seed storage buildings can be divided into three categories:
① Long term storage facility, temperature below -10 ℃, relative humidity around 30-40%, storage period of over 30 years;
② Mid term storage warehouse, temperature 0-5 ℃, relative humidity 40-60%, storage period of about 5-15 years;
③ Short term storage facility, temperature 10-15 ℃, relative humidity 50-60%, storage period 3-5 years;

characteristic:
1. The touch screen LCD operation interface can select the optimal cooling or dehumidification operation mode according to the different types of stored goods, with high control accuracy.
2. Dual temperature dual standby system, dual compressors, dual air ducts. When the first system fails, the other system immediately starts to ensure uninterrupted operation of the system.
3. Can communicate with computers and record data. Fully achieve unmanned monitoring, continuously collect and record temperature and humidity changes at monitoring points in real-time 24 hours a day, and display and record monitoring information in real-time through various methods such as digital, graphic, and image. The monitoring points can be expanded to thousands of points.
4. Temperature and humidity alarm upper and lower limits can be set for each monitoring point, and an alarm signal can be automatically issued when abnormal data occurs at the monitored point. The alarm methods include on-site multimedia audio, sound and light alarm, network client alarm, mobile SMS alarm, etc. Upload alarm information and conduct local and remote monitoring.
5. The development of control software adopts software engineering management, with strong openness and scalability. Due to the system design concept of hardware function software and the modular and communication network design of system hardware, the system can upgrade software functions and expand hardware types as needed.
6. Sensor type: Platinum resistor
7. Communication interface: RS485, USB
8. Record storage function: It also has a QR code management system for seed storage and retrieval
9. External sound and light alarm and SMS alarm (optional)
