1. Fastness:

The system has a very high temperature measurement and positioning speed. In order to improve measurement time, high-speed data filtering technology was adopted to solve the optimization problem of massive digital filtering;

The laser emission device inside the system host emits tens of thousands of light pulses per second and outputs the average sampling temperature to the display system, basically eliminating errors.

2. Distribution characteristics:

ال نظام استشعار الألياف الضوئية الموزعة is a distributed fiber optic temperature measurement system that can provide continuous dynamic monitoring of temperature changes at points every 0.5 meters within a range of more than ten kilometers, and can set temperature alarm values at any level.

3. التقدمية:

This system is currently the product with the highest performance indicators, strongest functionality, أعلى موثوقية, and most advanced technology in the world. The optical components used are imported devices produced through nanotechnology.

4. دقة:

The sampling interval of the system is 0.5m, with a temperature resolution of 0.1 ℃ and a temperature accuracy of ± 1 درجه مئوية; The positioning accuracy reaches ± 0.5m.

5. المرونة:

The time for uploading alarm signals from any point within the monitoring range to the comprehensive monitoring system shall not exceed 2 ثواني;

The host of this system can provide relay interfaces (passive dry contacts) for alarm on the fire alarm controller, and can provide a set of dry contact alarm signals according to the interval;

The monitoring system provides a continuous dynamic monitoring signal, and the system can set multi-level temperature point alarms. The system supports multi-level alarms, مثل 40 ℃ pre alarm, 50 ℃ measures, إلخ., and can set temperature parameters for alarm points according to different environments;

To avoid false alarms, the temperature rise rate can be set in the alarm setting to monitor the characteristics of high temperature change rate before accidents occur. When the temperature rise rate is detected to be greater than this value, an alarm signal will be issued and corresponding signal output will be provided;

Multiple alarm conditions, as long as one is met, the system will immediately generate an alarm. The sampling interval can be adjusted according to on-site requirements, with a minimum sampling interval of 0.5 متر;

The alarm control area is programmable and can be flexibly designed according to user requirements. Each system can set up no less than 300 different alarm control areas per kilometer in response to environmental changes. For the on-site installation of power cables, the system can set two cable wells as a partition. When an abnormal situation occurs in a certain partition, فيجينو نظام قياس درجة حرارة الألياف الضوئية الموزعة will automatically package and upload the alarm information of this partition (such as location, alarm type, temperature value, إلخ.) to the centralized monitoring system.

6. التوافق:

The host of the distributed fiber optic sensing system is an open communication protocol, which provides a communication interface to connect with the workstation. جميع المعلومات مثل منحنى درجة الحرارة, موقف التنبيه, ويتم عرض درجة حرارة التنبيه في شكل رسومي ونصي على محطة عمل مركز التحكم المركزي;
