Characteristics of China’s Ibinahagi ang Fiber Optic Temperature Sensing System

1. Kabilisan:

Ang sistema ay may napakataas na pagsukat ng temperatura at bilis ng pagpoposisyon. Upang mapabuti ang oras ng pagsukat, 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:

Ang distributed fiber optic sensing system is a distributed fiber optic temperature measurement system that can provide continuous dynamic monitoring of temperature changes at points every 0.5 metro sa loob ng hanay na higit sa sampung kilometro, at maaaring magtakda ng mga halaga ng alarma sa temperatura sa anumang antas.

3. Progressiveness:

This system is currently the product with the highest performance indicators, pinakamalakas na pag-andar, pinakamataas na pagiging maaasahan, at pinaka-advanced na teknolohiya sa mundo. The optical components used are imported devices produced through nanotechnology.

4. Katumpakan:

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

5. Kakayahang umangkop:

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

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;

Ang sistema ng pagsubaybay ay nagbibigay ng tuluy-tuloy na dynamic na signal ng pagsubaybay, at ang sistema ay maaaring magtakda ng mga multi-level na temperatura ng mga alarma sa punto. Sinusuportahan ng system ang mga multi-level na alarma, tulad ng 40 ℃ pre alarm, 50 ℃ measures, atbp., 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 metro;

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, Mga FJINNO ipinamahagi na sistema ng pagsukat ng temperatura ng fiber optic will automatically package and upload the alarm information of this partition (such as location, alarm type, halaga ng temperatura, atbp.) to the centralized monitoring system.

6. Pagkakatugma:

The host of the distributed fiber optic sensing system is an open communication protocol, which provides a communication interface to connect with the workstation. All information such as temperature curve, alarm position, and alarm temperature are displayed in graphic and textual form on the central control center workstation;

Maaaring ikonekta ang system sa iba pang mga control device gaya ng PC at fire alarm system sa pamamagitan ng mga output form gaya ng RS232, RS485, built-in relays, RJ45, o iba pang mga pang-industriyang protocol, upang magsagawa ng tunog at liwanag na mga alarma, at ang output ng signal ay tumpak at kumpleto;

The distributed fiber optic sensing system can output signals in segments and levels according to different alarm zones to meet the needs of different control panels;

7. Seguridad:

System software authorization management, secure and reliable;

Users can update the system for future upgrades and maintenance;

The distributed fiber optic sensing system has a security recording function, which can store all historical data since the system’s operation and can be downloaded using a portable computer;

If the fiber optic cable is damaged, the system can locate the damaged point, have self diagnosis function, and fuse it through the fiber optic fusion splicer, which is very important for effective online monitoring implementation;
