Embodiment 1

[0054] An intelligent optical fiber energy transmission sensor monitoring system and network have a temperature monitoring function, see figure 1 shown.

[0055] The transmitter single-chip microcomputer 7, 12, 17 of the transmitter central control unit 2 controls the temperature monitoring module 10, 15, 20 to detect the working temperature data of the laser 9, 14, 19 in real time through the data line, and then sends it to the serial port server through the serial port of the transmitter single-chip microcomputer 6. The serial port server 6 transmits it to the display control terminal 1 for display.

[0056] The receiving end single-chip microcomputer 32, 39, 46 measures the ambient temperature data of the receiving end through the data line control sensor 33, 40, 47, and controls the temperature and power feedback control module 34, 41, 48 to measure the temperature data of the photoelectric converter 29, 36, 43 and the power data of the chargers 30, 37, 44, and then pass ...

Embodiment 2

[0059] from figure 1 It can also be seen from the figure that an intelligent optical fiber energy transmission sensor monitoring system and network has a laser (9, 14, 19) for the central control unit 2 at the transmitting end and a photoelectric converter (29, 36, 43) for the receiving end module 4 ) The temperature protection function, and the function of setting the high temperature working threshold.

[0060] When the temperature monitoring module (10, 15, 20) of the central control unit 2 at the transmitting end detects that the temperature of the laser (9, 14, 19) exceeds the set threshold, or the temperature and power feedback control modules 34, 41 of the receiving end module 4 When , 48 detects that the temperature of the photoelectric converter 29, 36, 43 exceeds the set threshold, the transmitting-end single-chip microcomputer 7, 12, 17 of the transmitting-end central control unit 2 controls the laser drive 8, 13, 18 to turn off the laser 9, 14, 19 At the same time...

Embodiment 3

[0067] An intelligent optical fiber energy transmission sensor monitoring system and network has the function of automatic power storage of the receiving end module 4 and the function of setting the minimum power threshold for the chargers 30, 37, 44.

[0068] When the temperature and power feedback control module 34, 41, 48 of the receiving end module 4 detects that the power of the charger 30, 37, 44 is lower than the set minimum power threshold, it notifies the receiving end single-chip microcomputer 32, 39, 46, via The serial port of the single-chip microcomputer at the receiving end is connected to the optical fiber transceiver (31, 38, 45), communication optical fiber (23, 25, 27) and optical fiber transceiver module 11, 16, 21, and to the single-chip microcomputer 7, 12, 17 sends a specific serial port data packet; after receiving the serial port data packet, the transmitting end microcontroller 7, 12, 17 of the central control unit 2 of the transmitting end controls the...

Abstract

The invention discloses an intelligent optical fiber energy transmission sensing monitoring system and network. The system comprises a display control terminal, a transmitting end central control unit, an optical fiber channel and a receiving end module; high-temperature working thresholds are set for the laser and the photocell respectively, when the temperature exceeds the thresholds, a single-chip microcomputer of the transmitting end central control unit turns off the laser through a drive circuit, and a charger starts to work at the moment to provide electric energy for the receiving module; and the lowest power threshold value is set for the charger, and when the power of the charger is lower than the power threshold value, the single-chip microcomputer in the central control unit starts the laser through the drive circuit, the photoelectric converter work to perform photoelectric conversion. And continuous and reliable work of the system and the network is ensured through cyclicand alternate energy supply. Finally, the temperature and power of the transmitting end and the receiving end are comprehensively monitored and displayed, automatic temperature protection is carriedout on the transmitting end laser and the receiving end photoelectric converter, and automatic power storage is carried out on the receiving end module.
