Abstract
The utility model relates to a multiple probe fiber visible light sensor, which is composed of a probe 5, a probe connection fiber 4, a collimator 3, a signal transmission fiber 2 and a ST fiber connector 1, multiple probes can monitor a visible optical signal in a respective scope, the monitored signal can be gathered in the collimator, and the gathered signal is sent to a standard fiber connector by the signal transmission fiber. The power supply is not required for the detection and transmission process of the light signal. The multiple probes fiber visible light sensor has the active effects that 1) one sensor can detect multi-point light signal, the channel number of a photoelectric conversion terminal can be greatly reduced, so that hundreds of point visible light detection enables easy realization; 2) one sensor can carry multiple probes, the required quantity for the sensor for monitoring the points with certain quantity can be reduced, so that monitoring system cost can be greatly reduced; and 3) a whole set of sensor is passive from the signal detection to the signal transmission, the sensor signal is not influenced by extraneous electromagnetic environment, and the sensor in favor of increasing the stability and reliability of light detection and transmission.
Description
Technical field
The present invention relates to a kind of many probe optical fiber visible light sensors, belong to the light activated element field, be mainly used in the visible light monitoring of narrow enclosure space, or be used for the arclight monitoring in transformer station's controller switching equipment.
Background technology
In the power test chamber or transformation and distribution system usually need that the important area that electric arc may take place is carried out arc light and survey, come the judgment device running status or need not carry out emergency processing with this, suitable visible light sensor is the precondition that solves this class problem.These environment often require used sensor to have relatively low cost, higher sensitivity, bigger monitoring angle, stronger electromagnetic environment adaptive faculty and multiple spot monitoring function.
The principle of work of existing visible light sensor mainly is, utilize photoresistance, photodiode or phototriode that visible light is surveyed, obtain the electric signal corresponding with light source, adopt again subsequent conditioning circuit to this electric signal compensate, processing such as amplification, shaping, the electric signal that output at last and measuring system adapt.The shortcoming of this mode is: sensor needs the power supply power supply, and signal is interfered easily during forceful electric power magnetic environment length Distance Transmission.In addition, also having Fibre Optical Sensor to can be used for visible light at present surveys, its main application is the control for communication field or industrial process, do not carry multi-probe function, multiple spot monitoring then needs to be equipped with the sensor with the monitoring point equal number, makes the monitoring system cost that raising by a relatively large margin be arranged.
Also do not survey at the multiple spot visible light at present both at home and abroad, possess design, patent or the product of many probes optical fiber visible light sensor of characteristics such as optics simple in structure, with low cost, pure is passive, forceful electric power magnetic environment adaptive faculty simultaneously
The present invention overcomes the above-mentioned shortcoming of traditional visible light sensor from principle, effectively solves technical matterss such as multiple spot monitoring, forceful electric power magnetic environment adaptability.Reach simultaneously and optimize sensor construction, reduce the purpose of installation cost significantly.
Summary of the invention
The object of the present invention is to provide a kind of simple and practical, anti-electromagnetic interference capability strong, have with great visual angle, many probes optical fiber visible light sensor with low cost, in the hope of being used for the fiber-optic probe of transformation and distribution system electric arc light detection, power test chamber or other use occasion.
The objective of the invention is to realize by following approach: a kind of many probe optical fiber visible light sensors, it is characterized in that it is connected optical fiber, collimating apparatus, signal transmission fiber and the ST joints of optical fibre and formed by probe, probe, a plurality of probes are monitored the visible light signal in the scope separately, the signal that monitors gathers in collimating apparatus, to gather the joints of optical fibre that signal is sent to a standard by signal transmission fiber again, the detection of light signal and transmission course do not need power supply.
Good effect of the present invention is: 1. a sensor can detect the multiple spot light signal, reduces the port number of opto-electronic conversion end significantly, makes the visible light of hundreds of points detect the realization easily that becomes.2. because a sensor can carry a plurality of probes, reduced the quantity of the required sensor of point of monitoring some, the monitoring system cost is reduced significantly.3. to transmit from the acquisition of signal to the signal all be passive to a whole set of sensor, and sensor signal can not be subjected to the influence of external electromagnetic environment, is conducive to improve that visible light is surveyed and stability and the reliability of transmission.

Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is functional part synoptic diagram of the present invention
Fig. 2 is the present invention and monitoring system connection diagram
Fig. 3 arranges synoptic diagram for embodiment of the invention probe
Embodiment
Fig. 1 is functional part synoptic diagram of the present invention, and probe system is made up of a plurality of probes 5, and the quantity of probe 5 is the positive integer greater than 1, and configurable collector lens enlarges the ranges of incidence angles of probe received light line in the probe.Connection optical fiber 4 by separately is connected with collimating apparatus 3, and collimating apparatus 3 can connect optical fiber with many probes accurately dock with signal transmission fiber, and the loss minimum of optical signal power on the assurance joint face.Signal converges the back in collimating apparatus and is transferred to standard fiber joint 1 by signal transmission fiber 2, and the joints of optical fibre 1 are standardized component, can be connected by the photoelectric conversion module of these parts with the outside.Enter photoelectric conversion module then and carry out the signal processing.The length of above-mentioned connection optical fiber generally requires less than 10m, and the length of signal transmission fiber generally requires less than 100m.
Fig. 2 has illustrated being connected of a plurality of sensors and optical signal detecting and treatment circuit 6 corresponding passage 1～passage n.Obviously, this reduces significantly than each probe directly is connected needs with treatment circuit port number, makes the low-cost monitoring of multi-point signal become real.
Fig. 3 has illustrated probe of the present invention to place the different compartments in the cabinet, and a cabinet only needs a sensor just enough.Visible light or arc light appear in compartment arbitrarily, and monitoring equipment all can obtain corresponding signal synchronously.
Invention has been described according to specific exemplary embodiment herein, and to one skilled in the art, it will be apparent carrying out suitable replacement or revise under not departing from the scope of the present invention.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present invention, scope of the present invention is defined by appending claims.
