Embodiment 1

[0024] Example 1: Such as figure 1 , figure 2 , image 3 , Figure 5 , Figure 7 As shown, a fiber optic oil spill prevention control system includes an electric valve 1, an audible and visual alarm 2, and a computer 3 connected to the fuel supply system, and also includes a fiber optic liquid level for detecting the oil spill level in the oil filling container Switch 4, an optical fiber controller 5 for controlling an optical fiber liquid level switch, the optical fiber liquid level switch 4 and the optical fiber liquid level switch controller 5 are connected by an optical cable, and the sound and light alarm 2 is connected to the optical fiber liquid The position switch controller 5 is connected through a signal line; the electric valve 1 and the optical fiber level switch controller 5 are connected through a signal line.

[0025] The optical fiber type liquid level switch 4 includes an isolation box 4-7, a floating ball 4-9, and a floating ball connecting rod 4-2. An optical ...

Embodiment 2

[0029] Example 2: Such as Figure 4 , Image 6 As shown, it is the same as embodiment 1, except that the optical fiber type liquid level switch 4 includes isolation box 4-7, floating ball 4-9, and floating ball connecting rod 4-2, on the side wall of isolation box 7. There is an optical cable clamping joint 4-18, the floating ball connecting rod 4-2 is set through the isolation box 4-7 through the guide post 4-10, and is connected to the isolation box 4-7 through the lock nut 4-3 Fixed, the floating ball 4-9 is arranged at the end of the floating ball connecting 4-2 below the isolation box 4-7; the isolation box 4-7 is divided into an upper cavity and a lower cavity by a partition; in the upper cavity A collimator bracket 4-11 is provided. The collimator bracket 4-11 is equipped with a collimator 4-13 and a light blocking axis 4-12 for blocking the collimator output parallel light. The light blocking axis 4-12 is a magnetic material, the collimator 4-13 is arranged below the li...

Embodiment 3

[0031] Embodiment 3: The present invention also provides a control method of a fiber-optic liquid level switch controller. When the spilled oil level in the oil filling container reaches the set value, the fiber-optic liquid level switch 4 arranged in the oil filling container issues an early warning and alarm The optical fiber signal is transmitted to the optical fiber level switch controller 5 through the optical cable. The optical fiber level switch controller 5 converts the early warning and alarm optical fiber signals into early warning and alarm electrical signals, and sends out the early warning and alarm signals, and closes at the same time The electric valve 1 stops filling the oiling container, and the fiber optic level switch controller 5 simultaneously sends the warning and alarm through the RS485 signal converter 5-16 of the fiber optic level switch controller 5 and uploads the information to the computer 3 for oil spill Early warning and alarm.
