Liaocheng Commercial Building Civil Air Defense Biological Alarm

1、 Technical principles

Biological alarm is based on biosensing technology, which uses specific biological recognition elements (such as enzymes, antibodies, nucleic acid aptamers, cells or tissues) to undergo specific biochemical reactions with target analytes, converting biological signals into detectable physical or chemical signals (such as optical signals, electrical signals, thermal signals, etc.). After amplification, conversion and analysis by signal processing modules, it achieves real-time monitoring and alarm of specific substances or environmental parameters. Its core lies in the high selectivity and sensitivity of biometric elements, which can accurately identify target substances in complex matrices and provide a specific recognition basis for subsequent signal conversion.Liaocheng Commercial Building Civil Air Defense Biological Alarm

2、 Core functions

7.Accurate identification of target substances: Equipped with multiple biometric components, it can specifically identify different types of target analytes (such as toxic and harmful gases, heavy metal ions, pathogens, biotoxins, etc.), ensuring the accuracy and specificity of detection results and effectively avoiding interference from other substances.

8.Real time monitoring and data collection: With continuous monitoring capability, it can collect real-time data on the concentration or existence status of target substances, and record monitoring results at set time intervals to form a complete monitoring data curve, providing users with comprehensive dynamic change information.

9.Multi level alarm mechanism: Set multi-level alarm thresholds (such as warning value, alarm value, emergency alarm value) based on the safety threshold range of the target object. When the concentration of the target substance reaches or exceeds the corresponding threshold, alarm signals are issued through various means such as sound, light, vibration, etc. At the same time, the alarm information can be pushed to designated terminals through wireless communication modules to ensure that users can obtain danger information in a timely manner.

10.Data storage and transmission: Equipped with a large capacity data storage unit, it can store monitoring data for a certain period of time, making it convenient for users to query and analyze historical data. Supports wired (such asUSBEthernet) and wireless (such asWi-FiBluetoothLoRaTheNB-IoT）Multiple data transmission methods are used to achieve remote uploading and centralized management of monitoring data.

11.Self check and fault diagnosis: Equipped with system self check function, regularly inspect the activity of biometric components, sensor performance, circuit connections, etc. When a system abnormality or malfunction is detected, a fault alarm signal is automatically issued and the type and location of the fault are displayed on the screen, making it easier for maintenance personnel to carry out timely repairs and replacements.Liaocheng Commercial Building Civil Air Defense Biological Alarm

3、 Key technical parameters

12.Detection range: The detection range can be customized for different target objects. For example, for common toxic gases such as carbon monoxide, the detection range can be set to0-1000ppmFor heavy metal ions (such as lead ions), the detection range can reach0.01-10mg/LMeet the monitoring needs in different scenarios.

13.Detection limit: With high sensitivity, the detection limit is as low asppbevenpptlevel Regarding biotoxinsThe detection limit can reach0.1ng/mLCan issue timely warnings when the concentration of the target substance is extremely low.

14.Response time: The time from the target object coming into contact with the biometric element to the system issuing an alarm signal is short, usually the response time≤30Seconds, ensuring quick response in emergency situations.

15.Resolution: High resolution, able to accurately distinguish small changes in the concentration of target substances, with a resolution of up to0.01ppm(Gas) or0.001mg/L(Liquid) to ensure the accuracy of monitoring data.

16.Working temperature and humidity: Suitable for different environmental conditions, the working temperature range is generally-10℃-55℃The working humidity range is10%-90%RH(No condensation), ensuring stable operation in various scenarios such as indoor and outdoor.

17.Power supply mode: Supports multiple power supply modes, including AC power supply（AC 220V）And DC power supply（DC 5V/12V）Some portable devices can be equipped with rechargeable lithium batteries, which have a longer battery life≥8Hour by hour, meeting the needs of mobile monitoring.

18.Alarm method: Integrated sound alarm (volume)≥ 85dB@1m）TheLEDThe indicator light (red, yellow, green) and vibration alarm (suitable for portable devices) work together in multiple alarm modes to ensure effective transmission of alarm information.
