Technical Field
[0001] The invention belongs to the technical field of radio frequency and optical fiber communication, and in particular relates to a monitoring device based on a passive optical cross-connect box. Background Art
[0002] Driven by the development of the Internet of Things, network communications have matured. Automatic identification technology uses specialized identification devices to automatically obtain information about an object without contact. RFID utilizes radio frequency signals, with a reader transmitting electromagnetic waves. The antenna coil senses these signals and transmits them to the reader. This automated identification process eliminates manual labor and has become widely used.
[0003] Traditional optical cable management and inspections in optical cross-connect boxes present numerous challenges. Traditional cable surveys rely on a limited number of connected cables, typically only one at a time. This results in complex operations, low survey efficiency, and the need for documented drawings, which can be low-quality and error-prone. Traditional cable management requires paper labels, which is time-consuming for a 144-port optical cross-connect box. Changing and binding labels is a tedious process.
[0004] Purpose of the Invention
[0005] The purpose of the present invention is to provide a monitoring device based on a passive optical cross-connect box in order to address the defects of the prior art.
[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical solutions: a monitoring device system based on a passive optical cross-box, comprising: a fixed tag and an external monitoring device;
[0007] The fixed tag is used to be set on the optical fiber connector inserted into the optical cable interface of the optical cross-connect box, and sends a tag signal when receiving energy provided by the external reader through the external monitoring device and receiving light of a certain intensity;
[0008] The peripheral monitoring device is used to be set outside the optical cross-connect box, emits light that can be identified by the fixed tag, and can be connected to an external reader to provide energy to the fixed tag. By reading the tag signal, it is determined whether there is an optical cable resource at the corresponding location.
[0009] Furthermore, a light-triggered circuit device and a receiving antenna; the receiving antenna receives energy provided by an external reader through peripheral monitoring to power the light-triggered circuit device, and the light-triggered circuit device sends a tag signal when receiving light of a certain intensity.
[0010] Furthermore, the peripheral device monitoring includes a plug-in board, an encoding circuit and one or more power supply light signal circuits provided on the plug-in board; the one or more power supply light signal circuits are provided in parallel on the plug-in board, and each power supply light signal circuit includes an RFID reader antenna and an optical signal transmitting circuit;
[0011] The RFID reader antenna is used to connect to the reader; the optical signal transmitting circuit is used to transmit optical signals; the encoding circuit is used to control the on-off connection between the RFID reader antenna and the reader, and the plug-in board fixes the entire peripheral monitoring above the optical cable interface of the optical cross-box.
[0012] Furthermore, the number of the energized luminous signal circuits is the same as the number of the optical cable interfaces on the optical cross-connect box near the plugboard and their positions match, and the optical signal transmitting circuits in each group face the fixed labels on the corresponding optical fiber connectors inserted into the optical cable interfaces.
[0013] Furthermore, the length of the plug-in board is consistent with the width of the optical cross-connect box, and a buckle for fixing the optical fiber connector is provided on the plug-in board.

[0017] Furthermore, when the reader fails to receive label information and determines that the corresponding optical cable interface is empty, or the optical fiber connector label is damaged, the LED circuit turns off.
[0018] The present invention adopts a new design of the cover plate to propose a monitoring device based on a passive optical cross-box, which greatly improves the efficiency of inspection. Compared with flipping paper labels one by one and comparing and judging them one by one with the human eye, the efficiency of electronic tags is fast and accurate, and it is a fragmented and flexible inspection method. The passive optical cross-box inspection device designed by the present invention can determine whether resources are fully utilized. By adding the characteristics of optical signal triggering to RFID technology, it solves the current problems of inaccurate RFID tag recognition and crosstalk in optical cross-boxes. In the process of intensive identification of multiple tags, it can effectively avoid the omission and cross-reading of tags. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0025] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or apparatuses.
[0026] This patent provides a monitoring device design based on passive optical cross-connection. The optical tag is used as an identification device for the optical fiber connector. The basic principle is that the optical tag receives the electromagnetic waves emitted by the reader and does not carry any information. It only converts energy to provide energy for the tag. Within the coverage range of the radio frequency antenna, when the optical tag receives a certain intensity of light, the tag will send the tag information to the reader. Figure 1 The basic schematic diagram is shown.
[0027] Optical cross-connect box Figure 2 ) The eaves plug-in board 1 design is added to the upper part, and the label is fixed on the optical fiber connector. The eaves plug-in board is installed on the optical cross-connect cabinet and corresponds to the optical cable interface one by one. The optical fiber connector does not change the original size, but is affixed with an optical label and fixed on the connector, which can be adapted to the traditional optical cable interface, such as Figure 3 and 4 The label 2, optical fiber connector 3, and buckle 4 are shown.
[0028] The optical cross-box eaves plug-in board includes an RFID reader antenna, a light-emitting diode circuit 5, and an encoder circuit. The light-emitting diode circuit and the reader antenna lead two wires to the reader through the encoder circuit ( Figure 5), the encoder circuit is designed in the eaves plug board. The encoder circuit can control the on-off of the reader antenna to the reader in each path of the optical cross-connect box. After the reader transmits radio frequency energy through the antenna, the optical signal transmission circuit (light-emitting diode circuit) is started and sends an optical signal. The entire circuit can be designed as a conductive strip and can be separated from the eaves plug board.
[0029] The optical label attached to the outside of the optical fiber connector is strictly consistent with the size of the optical fiber connector, and the label contains a light-triggered circuit device.
[0030] The size design of the eaves plug-in board is consistent with the width of the optical cross-box. The optical label is close to the optical fiber connector. The eaves plug-in board has a snap design to fix the optical fiber connector, so that the label and the eaves plug-in board can fit perfectly.
[0031] The side of the optical fiber connector with the label on it is close to the side of the eaves plug-in board, and corresponds one-to-one with the light-emitting diode on the cover plate, and the positions match.
[0032] The reader sends radio frequency signals through the RFID radio frequency antenna inside the eaves plug board. It does not carry any information and only performs energy conversion to provide energy for the optical tag. The optical signal transmitting circuit (light emitting diode circuit) sends optical signals to the optical tag.
[0033] When an optical tag receives light of a certain intensity within the coverage area of the RF antenna, it sends its tag information to a reader. There is only one reader, which reads and writes to the optical tag group through an encoder circuit.
[0034] The light-emitting diode can detect whether the optical cable resource exists by corresponding to the optical fiber connector. When the optical cable port is empty or the optical fiber connector label is damaged, the reader cannot receive the label information and the light-emitting diode goes out.
[0035] Two wires extend from one side of the eaves cover and connect to an external reader for reading information. The light emitter emits light, which is both visible and invisible, within the optical tag's recognition range. The tag's internal optical signal detector measures the intensity of the light signal. When the signal exceeds a threshold, the tag triggers the tag to send a signal to the reader.
[0036] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
