When selecting high-quality distributed optical fiber temperature measurement system manufacturers, we should comprehensively consider the technical progressiveness of their products, indicadores de desempeño (such as temperature measurement accuracy, precisión de posicionamiento, measurement length), reputación en el mercado, after-sales service and whether they can meet the customized needs of specific application scenarios.
1、 High quality standards for manufacturers of sistemas distribuidos de medición de temperatura por fibra óptica
1.1 Product performance aspect
Precisión de la medición de temperatura
High precision temperature measurement is one of the key indicators for measuring distributed fiber optic temperature measurement systems. Por ejemplo, in some application scenarios that are sensitive to temperature changes, como la industria petroquímica, it is necessary to accurately transmit temperature data of all temperature gradients underground. The temperature accuracy may require 0.01 or even lower to detect abnormal points through interpretation software. en el sistema de energía, accurate temperature measurement is crucial for monitoring the operating status of equipment such as cables and bus ducts. Excessive accuracy error may lead to misjudgment of equipment overheating. Products with an accuracy of around ± 0.5 ℃ – ± 1 ℃ are generally more common.
precisión de posicionamiento
This indicator reflects the system’s ability to locate temperature anomalies. In scenarios such as tunnels, grandes edificios, etc., when a fire or local overheating occurs, quickly and accurately locating the location of the abnormal point is the key to timely handling the problem. Some advanced systems can achieve a positioning accuracy of ± 0.05 metros (5 centímetros), while ordinary systems may be around ± 1 metro. The positioning accuracy is mainly limited by the device’s ability to collect data at a fast speed, which results in high positioning accuracy. Esto requiere que el dispositivo tenga capacidades de recopilación de datos de alta velocidad..
Medir longitud
La longitud de la fibra que se puede combinar con un solo canal también es un factor importante a considerar en el rendimiento.. Para un seguimiento regional a gran escala, como líneas de transmisión de larga distancia o monitoreo de oleoductos, se requieren longitudes de medición más largas. Sin embargo, un aumento en la longitud de la medición puede traer algunos problemas. Por ejemplo, dentro de 10 km, La precisión de la temperatura de la cabeza y la cola es aproximadamente 2-4 veces, mientras que a 20 km, La precisión de la temperatura de la cabeza y la cola es aproximadamente 6-10 veces, indicando que la precisión de la temperatura de la cabeza y la cola es alta y baja, y cuanto más larga sea la fibra, cuanto más largo sea el tiempo de medición también aumentará.
Resolución espacial de detección de temperatura
Similar a la resolución de píxeles de una imagen., El nivel de resolución espacial de detección de temperatura determina si el sistema puede detectar cambios de temperatura en pequeños puntos críticos de manera oportuna.. Si la resolución espacial de la detección de temperatura es demasiado baja, Es posible que los puntos de acceso pequeños no reciban advertencias oportunas durante el calentamiento temprano., y ya es demasiado tarde para informar la ubicación y temperatura del incendio cuando realmente ocurre. Actualmente, Este indicador de desempeño está muy problemático tanto a nivel nacional como internacional., con algunos factores limitantes, incluida la capacidad del dispositivo para recopilar datos de alta velocidad, pulsos ópticos de banda ancha, límite de bits para la adquisición de datos de alta velocidad, ancho de banda de señal, y capacidad de detección optoelectrónica.
Tiempo de medición
El tiempo de medición se refiere al tiempo necesario para actualizar todos los datos de temperatura de la fibra.. En el ámbito de la protección contra incendios., there is a high requirement for measurement time. Generalmente, dentro 1-3 artículos de segunda clase, all fiber optic temperatures in a channel need to be updated and real-time judgment of whether there is a fire alarm; In the petroleum field, underground temperature measurement does not have such strict requirements for time, and the temperature data of the optical fiber can be updated every 2 minutes or even longer.
1.2 Product stability aspect

A stable system can reduce monitoring interruptions caused by equipment failures and avoid missing important temperature change information.
Fiber quality
As a key component of temperature measurement systems, the quality of temperature sensing fibers is crucial. Fiber optic cables should have characteristics such as high temperature resistance, resistencia a la corrosión, and strong electromagnetic interference resistance. Por ejemplo, in the temperature monitoring of pipelines, tanques de almacenamiento, and other equipment in the chemical industry, optical fibers need to be able to withstand complex chemical environments and possible high temperature situations; en el sistema de energía, it is necessary to be able to operate normally in strong electromagnetic environments. Además, the structure of the optical fiber should be stable and not easily broken. When bending and laying, También debe asegurarse de que no cause pérdidas excesivas..
