Automatic alarm function of intelligent reagent cabinet

　　1. Function overview

　　The automatic alarm function of the intelligent reagent cabinet is an important security and monitoring mechanism. It can automatically send an alarm signal when abnormal conditions occur in the reagent cabinet, such as abnormal temperature and humidity, reagent leakage, cabinet door abnormal opening, etc., to remind relevant personnel to take measures in time to avoid the occurrence of damage, loss or safety accidents.

　　2. Trigger conditions

　　Abnormal temperature and humidity environment: When the temperature or humidity in the reagent cabinet exceeds the preset safety range, the alarm function will be triggered. For example, for some temperature-sensitive reagents, such as enzyme reagents, the storage temperature is usually required at 28 ℃. If the temperature sensor detects that the temperature has increased above 10 ° C, the system will issue an alarm. This is because too high a temperature may cause the enzyme's activity to be lost, rendering the reagent ineffective. The temperature sensor and humidity sensor in the cabinet detect that the environmental parameters exceed the preset range, for example, the temperature or humidity is too high, which may cause reagent deterioration or security risks.

　　Abnormal opening of the cabinet door: The smart reagent cabinet is usually equipped with an access control system, which will also trigger an alarm when the cabinet door is opened without authorization or outside the specified time. For example, during off hours in the laboratory, the cabinet door should normally be closed and locked. If someone unlawfully opens the cabinet door, the alarm system will immediately sound an alarm to prevent the reagent from being stolen or misused.

　　Abnormal reagent leak detection: Some advanced intelligent reagent cabinets are equipped with leak detection sensors. When the reagent leaks and the liquid comes into contact with the sensor, the alarm system activates. For example, in the smart reagent cabinet in the chemistry laboratory, there is a corrosive acid reagent, and once the acid leaks and is detected by the sensor, an alarm will be triggered in order to clean up the leak in time to avoid corrosion of the reagent cabinet and other reagents.

　　Equipment failure: If the cooling equipment, heating equipment, ventilation equipment or monitoring equipment (such as sensors) in the reagent cabinet fails, an alarm will also be triggered. For example, if the compressor of the refrigeration equipment stops working, causing the temperature to rise, the system will issue a fault alarm to remind the maintenance personnel to repair the equipment.

　　Illegal operation: When unauthorized personnel attempt to access the reagent cabinet or conduct illegal operations, the intelligent reagent cabinet will identify and trigger an alarm through biometric identification, fingerprint recognition and other technologies.

　　3. Alarm method

　　Audible alarm: This is one of the common alarm methods. The reagent cabinet will emit a loud alarm, which can attract attention in the laboratory or storage area. The volume of sound can usually be adjusted according to the noise level of the environment to ensure that it can be heard. For example, in a quiet laboratory environment, the alarm can be set to a relatively low volume; In a noisy factory environment, the volume needs to be set high enough.

　　Light alarm: In addition to the sound alarm, the reagent cabinet will also alarm by flashing lights. This can be useful in noisy environments or for people who are hard of hearing. The light is usually installed on the top or front of the reagent cabinet and is bright in color and easy to be found. For example, a red flashing light can draw attention from a long distance.

　　Remote notification: The smart reagent cabinet can also be connected through the network to send alarm information to the relevant personnel's mobile phone or computer. This method allows personnel to receive timely alerts even if they are not near the reagent cabinet. For example, laboratory managers can receive alarm information through the mobile APP, including details such as the type of alarm, time and location of the reagent cabinet, so that appropriate measures can be taken immediately.

　　4. Management and maintenance of alarm system

　　Regular testing: In order to ensure the effectiveness of the alarm function, it is necessary to regularly test the alarm system. Various trigger conditions can be simulated, such as manually adjusting the data of the temperature and humidity sensor to make it out of range, or deliberately opening the cabinet door, etc., to check whether the alarm methods such as sound, light and remote notification work normally. It is generally recommended to do a simple test once a week or monthly, and a full test once every quarter or half a year.

　　Update alarm Settings: As reagent storage requirements change or the laboratory environment changes, it may be necessary to update alarm Settings in a timely manner. For example, when the new reagent is stored in the reagent cabinet, its requirements for temperature and humidity are different, and the temperature and humidity alarm range needs to be adjusted accordingly.

　　Maintenance alarm equipment: Maintenance of the alarm equipment itself, including cleaning, checking whether the connection line is loose, etc. For example, the horn of a sound alarm may affect the clarity of the sound due to dust accumulation and need to be cleaned regularly.

　　The automatic alarm function of the intelligent reagent cabinet is one of its core features, which mainly relies on a variety of built-in high-precision sensors and advanced identification technologies (such as RFID, two-dimensional code, etc.) to ensure the safe storage and compliance of reagents. The following is a detailed introduction to the automatic alarm function of the intelligent reagent cabinet:
