Description

[0002] In the power system, there are a lot of monitoring data, such as current, voltage, load and other data. These data are often transmitted through optical fiber, using the advantages of optical fiber such as large transmission capacity and strong anti-interference ability to ensure the timeliness and reliability of power data.

[0003] During optical fiber transmission, a patch panel is often used to realize the wiring connection between the optical fiber and the optical communication equipment and between the optical communication equipment. Then, whether these wiring connections are continuously stable is related to the working stability of the entire power system. Just as the power dispatching and other work of the power system mentioned above are realized based on the monitoring data transmitted by the optical fiber, in the prior art, whether the optical fiber of the patch panel is in a connection state (in the connection state, the data can be continuously uploaded, and in the disconnected state, the power dispatching command center cannot receive the power data of each monitoring node) is realized by manpower, which is inefficient and requires repeated identification by the staff, which is not conducive to timely troubleshooting.

[0031] The present invention is further described in detail below:

[0032] The present invention provides an optical fiber connection and disconnection detection and indication device for an optical fiber distribution frame, comprising a detection module, a working indication module and a fault indication module;

[0033] The detection module is used to sense the on / off status of the optical fiber of the optical fiber distribution frame and output a detection signal;

[0034] The working indication module is used to receive the detection signal output by the detection module and indicate that the current state is normal when the optical fiber of the optical fiber distribution frame is normal;

[0035] The fault indication module is used to receive the detection signal output by the detection module, and indicates that the current state is a fault when the optical fiber in the optical fiber distribution frame is disconnected. Through the above structure, it is possible to accurately detect whether the wiring in the optical fiber distribution frame is a passage and to accurately indicate the working state and the fault state, thereby effectively improving the judgment efficiency, facilitating timely detection of faults and formulating corresponding troubleshooting measures.

[0036] In this embodiment, the detection module includes a resistor R2 and a photosensitive element;

[0037] One end of the resistor R2 is connected to the DC power supply VCC, the other end of the resistor R2 is grounded through the photosensitive element, and the common connection point between the resistor R2 and the photosensitive element serves as the output end of the detection module.

[0038] Among them, the photosensitive element is a thermistor PTC. When the thermistor PTC is used, its resistance is larger when there is light, and smaller when there is no light, that is, its resistance increases with the increase of light. The light includes visible light and invisible light, which will cause the thermistor PTC to have a corresponding resistance change.

[0039] In this embodiment, the work indication module includes an indicator light LED1, a resistor R6 electronic switch and a drive control circuit;

[0040] The power input end of the electronic switch is connected to the DC power supply VCC through the resistor R6, the power output end of the electronic switch is connected to the positive electrode of the indicator LED1, and the negative electrode of the indicator LED1 is grounded;

[0041] The control input end of the driving control circuit is connected to the output end of the detection module, and the control output end of the driving control circuit is connected to the control input end of the electronic switch.

[0042] The electronic switch is a transistor T4, which is an N-type transistor.

[0043] In this embodiment, the driving control circuit includes a resistor R5, a resistor R7, a resistor R8, a resistor R4, a transistor T2 and a transistor T3;

[0044] One end of the resistor R4 is connected to the output end of the detection module as a control input end of the drive control circuit, the other end of the resistor R4 is connected to the base of the transistor T2 and the transistor T3, the collector of the transistor T2 is connected to the DC power supply VCC through the resistor R5, the emitter of the transistor T2 is connected to the emitter of the transistor T3, the collector of the transistor T3 is grounded, the emitter of the transistor T2 is connected to one end of the resistor R8 through the resistor R7, the other end of the resistor R8 is grounded, and the common connection point between the resistor R7 and the resistor R8 serves as the control output end of the drive control circuit;

[0045] Among them, the transistor T2 is an N-type transistor, and the transistor T3 is a P-type transistor.

[0046] Wherein, the driving control circuit further includes a diode D1;

[0047] The anode of the diode D1 is connected to the common connection point between the resistor R7 and the resistor R8, and the cathode of the diode D1 is connected to the emitter of the transistor T2.

[0048] In this embodiment, the fault indication module includes a resistor R3, a resistor R1, an indicator LED2 and a transistor T1;

[0049] One end of the resistor R3 is the control input end of the fault indication module, the other end of the resistor R3 is connected to the base of the transistor T1, the emitter of the transistor T1 is connected to the DC power supply VCC through the resistor R1, the collector of the transistor T1 is connected to the positive electrode of the indicator LED2, and the negative electrode of the indicator LED2 is grounded;

[0050] Among them, the transistor T1 is a P-type transistor.

[0051] In this embodiment, a light guide strip is also included. One end of the light guide strip corresponds to the optical fiber joint in the optical fiber distribution frame, and the other end of the light guide strip faces the photosensitive element. Since the thermistor is directly arranged at the optical fiber joint or the optical fiber connector terminal, it will affect the optical fiber. Therefore, the light can be guided out through a light guide strip, so that the layout of the original connector and the terminal does not need to be changed, which is convenient for use. Figure 3 As shown, a light guide strip is arranged at each terminal, and a light guide strip 4 corresponds to an optical fiber connection and disconnection detection indicator device of an optical fiber distribution frame, and multiple optical fiber connection and disconnection detection indicator devices 2 of optical fiber distribution frames can be arranged on a base 1. Figure 3 In the figure, 3 represents the DC power supply VCC.

[0052] The working principle of the present invention is further described below:

[0053] The DC power supply VCC adopts an existing DC power supply, such as a battery, for example, after the mains is rectified and filtered, it is stabilized by an existing voltage stabilizing circuit. In practice, the output end of the DC power supply VCC is also grounded through a capacitor C1 to filter out interference and also to stabilize the voltage. When the optical fiber path is normal, the light guide strip guides the light to the thermistor PTC. At this time, its resistance is large and its voltage division is also large, so that the transistor T2 is turned on, T1 and T3 are both turned off, and then the transistor T3 is turned on, and the working indicator LED1 lights up, indicating that the current state is normal. When the optical fiber path fails, there is no light signal at the terminal of its connector. At this time, the corresponding PTC has a small resistance, the transistor T2 is turned off, and the transistor T1 is turned on, so that the fault indicator LED2 lights up, indicating that the current state is a fault, that is, the optical fiber is in a disconnected state. Figure 2As shown, in practice, a buzzer SP can also be connected in parallel to the indicator light LED2 to further provide a warning. When the transistor T2 is turned off, the junction capacitance between the base and the emitter of the transistor T4 exists, and the diode D1 and the emitter and collector of the transistor T3 are used for rapid discharge, thereby ensuring that the LED1 is extinguished in time, which is conducive to accurate fault indication.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
