Hoe u een gedistribueerd glasvezeltemperatuurmeetsysteem-INNO opzet

It is very simple to use, just need to perform the following four steps:

1) Insert temperature sensing optical cable

The connector of the temperature sensing optical cable must be correctly inserted into the device. The type of temperature sensing fiber optic cable connector is FC/APC. When inserting the optical cable plug, please make sure to align the protrusion on the plug with the groove in the socket, and then tighten the thread, zoals weergegeven in de volgende afbeelding:

When removing the connector from the adapter, please cover it with a protective cap to prevent dust from entering and affecting system performance.

2) Power on the device

Before powering on, connect the keyboard, mouse, and VGA display.

Power requirements: Wisselstroom 220V, 50Hz

Sluit het netsnoer aan op een stopcontact

Na aansluiting op de voeding, het systeem start automatisch op en voert het programma uit.

3) Wachten tot de zelftest van het systeem is voltooid

Nadat het apparaat is ingeschakeld, de software wordt automatisch geladen en uitgevoerd. Nadat de software is uitgevoerd, het start automatisch de detectie. Tijdens het detectieproces, de statusbalk wordt weergegeven: Systeem zelftest… Nadat de zelftest is voltooid, het wordt weergegeven: Normale collectie

4) Bekijk de temperatuur en het spectrum van glasvezelkabels

Schakel over naar de temperatuurcurvegrafiek en bekijk de realtime temperatuur van de optische kabel.

Schakel over naar de spectrale curvegrafiek en bekijk het spectrale signaal van de optische kabel.

The vertical axis represents the signal strength and voltage value; The horizontal axis represents the measurement position point.

The signal at around 250 points in the front is the internal fiber optic signal of the equipment, and the signal at the back is the measurement fiber optic signal.

The length of the optical fiber is displayed in red text above the curve, measured in points.

3.7 Glasvezelparameters

Klik op het menu: Instellingen | Glasvezelparameters, en de “Glasvezelparameters” dialoogvenster verschijnt,

Configureer onafhankelijk de glasvezelparameters voor elk kanaal.

Vanwege de verschillende eigenschappen zoals gewrichtsverlies, verliescoëfficiënt, verlies van fusiepunten, en aantal fusiepunten voor elke glasvezelkabel, het is noodzakelijk om na de constructie de glasvezelparameters voor elk kanaal afzonderlijk te corrigeren.

In de linkerlijst worden kanaalnamen weergegeven. Voordat u een kanaal instelt, selecteer het overeenkomstige kanaalnummer.

Uitgangspositie: De optische kabel komt overeen met de positie van de optische kabel in de software. As there is a reference fiber in the equipment, the starting position of the optical cable should be greater than the length of the reference fiber in the equipment. It is set up at the factory and does not require any modification.

Fiber length: reserved.

Demodulation coefficient: Temperature value T=a * x * x+b * x+c

A: Quadratic coefficient

B: Coefficient of first-order term

C: Constant coefficient

Import coefficient: The coefficient can be manually entered or directly imported from a file. Click “Import Coefficient” en de “Import Fiber Coefficient” dialoogvenster verschijnt:

Select a row corresponding to the fiber optic name and click the OK button.

Regional attributes: Fiber optic can be divided into multiple regions, and the attributes of each region can be configured separately. Regional attributes include: starting point of the region, temperature deviation, and transmission attenuation coefficient;

Add Area: Click the “Add” button to pop up the “Area” parameter dialog box,

Starting point position: the starting point position of the region;

Temperature deviation coefficient: The temperature deviation value in this area, the temperature measurement value plus the deviation coefficient;

Transmission attenuation coefficient: The optical fiber transmission attenuation coefficient in this area.

Delete Area: Select the row of the area to be deleted and click the delete button.

Modify Area: Double click the row of the area you want to modify with the mouse, en de “Area Parameters” dialoogvenster verschijnt.

If the optical fiber has multiple fusion points, the loss of each fusion point will cause the temperature curve to not be straight. Daarom, different parameters, temperature deviation, and transmission attenuation coefficient need to be set for the area between each fusion point, zoals weergegeven in de volgende afbeelding:

The temperature curve corresponding to the above figure can be set in three regions, as shown in the table below:

Transmission loss coefficient of temperature deviation at the starting point of the region
1 300 0 0.000008
2 1000 2 0.0000085
3 2000 2 0.0000095

Transmission loss coefficient: affects the slope of the temperature curve, and adjusting the transmission loss coefficient of the channel can correct the slope of the temperature curve.

Voorbeeld 1: Transmission loss coefficient=0.00000920

In Example 1, the set transmission loss coefficient is exactly the actual transmission loss coefficient of the optical fiber, and the blue temperature curve is relatively flat.

Voorbeeld 2: Transmission loss coefficient=0.0001220

In Example 2, the set transmission loss coefficient is greater than the actual transmission loss coefficient, and the blue temperature curve slopes upwards.

Voorbeeld 3: Transmission loss coefficient=0.00000620

In Example 3, the set transmission loss coefficient is smaller than the actual transmission loss coefficient, and the blue temperature curve slopes downwards.
