Description

Technical Field

[0001] The invention relates to a maintenance device for an optical fiber communication system, in particular to an intelligent maintenance device for an optical fiber network and an optical fiber full data detector thereof. Background Art

[0002] With the rapid development of optical fiber communication, the number of optical fiber lines is increasing. Due to the limited technology in the early stage of laying optical cables, scientific optical fiber routing management has not been achieved, resulting in chaos in the routing of optical fiber lines, involving all links from the trunk line to the end user, especially the ODF management of the computer room (abbreviation of Optical Distribution Frame, optical fiber distribution frame, used for the termination and distribution of the trunk optical cable at the local end of the optical fiber communication system, which can easily realize the connection, distribution and scheduling of optical fiber lines). The non-standard paper labels, loss, inaccurate wiring information, and changes in maintenance personnel have brought great hidden dangers to the later maintenance. When a line fails or an error occurs, the search for the line route is very cumbersome, time-consuming and labor-intensive, and it is simply unable to meet the customer's needs for network maintenance. This problem has also become a difficult problem in the optical fiber communication industry.

[0003] At present, fiber-optic communication has achieved large-scale coverage, especially the popularization of FTTH fiber-to-the-home. People's dependence on the network is increasing day by day. However, the inadequate supervision of fiber-optic network construction has resulted in poor quality of fiber-optic network construction. The acceptance of construction projects can only be judged by whether they are opened or not. It is impossible to accurately judge the loss and cracking of each section of optical fiber and each node in the optical fiber line, which seriously affects the user's experience of the fiber-optic network. Operators need to spend more money on network maintenance, and network users also have to bear the economic losses caused by network outages.

[0004] The existing technology mainly uses optical time domain reflectometer to detect optical fiber line loss and optical fiber end face loss. It uses the reflection loss phenomenon of light waves at optical fiber loss points and optical fiber connector coupling points to emit detection light waves in the optical fiber line, and detects the light waves returning from the original path to measure the distance between the loss point and the coupling point and the intensity of the reflected light waves at the point, thereby indirectly judging the connection loss and total line loss of the loss point and the coupling point. Although this equipment can perform high-speed and batch detection of loss points and coupling points on optical fiber lines and optical fiber lines, and can accurately locate fault points, it is expensive and cannot be equipped to ordinary construction personnel in large quantities. In addition, it is difficult to use, which makes this equipment rarely used in engineering construction. The key is that it is impossible to upload test data and on-site port number information to the server to form a complete optical fiber line routing topology map, so it is impossible to provide operators with complete information such as optical fiber node loss and loss change, which is in serious conflict with the increasing demand for network maintenance.

[0083] In another embodiment of the present invention, the optical power measurement module 135 includes a first optical power measurement unit 1351, a second optical power measurement unit 1352, a third optical power measurement unit 1353 and a fourth optical power module (not shown), the detection unit includes a line loss detection unit 141, a first end face loss detection unit 142, a second end face loss detection unit 142 and an end face loss calibration unit 143, the line loss detection unit 141 is connected to the first optical power measurement unit 1351, the first end face loss detection unit 142 is connected to the second optical power measurement unit 1352, the second end face loss detection unit 142 is connected to the third optical power measurement unit 1353, and the end face loss calibration unit 143 is connected to the fourth optical power measurement unit; the optical path unit includes a first optical path, a second optical path and a splitter 145, the first optical path is connected to the line loss detection unit 141 through a first optical cable The second optical path is connected to the emitting light source 136 through a second optical cable. The first optical cable and the second optical cable are coupled in the optical splitter 145 and then divided into a first coupled optical cable and a second coupled optical cable. The first coupled optical cable is connected to the first detection adapter through a first standard connector 146; the first end face loss detection unit 142 is installed on the first detection adapter; the second standard connector 147 is connected to the second coupled optical cable and is connected to the calibration connector 140 through a calibration adapter 149. The calibration connector 140 is connected to the third standard connector through an optical cable, and the third standard connector is connected to the second detection adapter. The detection port of the second detection adapter is different from the detection port of the first detection adapter, and is used to detect optical fiber connectors with different connection modes. The end face loss calibration unit 143 is installed on the calibration adapter 149, and the second end face loss detection unit 142 is installed on the second detection adapter.

[0084] Among them, the emitting light source 136 preferably emits 650nm visible light, and the emission is carried out by switching the 650nm emitting tube, and three power levels of high, medium and low are set, for example, 30mw, 10mw and 1mw can be preferably used respectively. The above powers are approximate values ​​and can be determined according to actual measurements when used. The emitting light source 136 can send coded light wave signals. When reaching another optical port connection point through the optical path, the leaked light activates the adapter with a detector in the tray on the ODF distribution frame, that is, the photon tag 5. The detector receives the signal, and through photoelectric conversion, it is converted into an electrical signal and uploaded to the photon tag transceiver box 2 connected to the top of the distribution frame. The photon tag transceiver box 2 judges which optical port is sent and the sent code content, and uploads the two codes together to the server 3, so that the server 3 obtains one or more code groups. The server 3 collects one of the code groups that is the same as the code carried in the emitted light wave to form a route, thereby realizing the route search function. When finding the connection point fault, the transmitting light source 136 controls the energy according to the distance. For example, if it is close, it sends weak light, so that the connection point with good quality will not leak light, and if it leaks light, it will upload the coding group. The server 3 can determine the optical port where the fault is based on the APP or the optical fiber full data detector 1; when the distance is far, it emits strong light, and the coding group uploaded to the server 3 by the optical port at a close distance is shielded, so that the light reaches the far end and becomes weak. A good connection point will not leak light, and a virtual connection point will report the coding group, and the fault point can be determined. When testing the connector end face loss in the optical port, the transmitting light source 136 emits light with weak power energy. If it can leak out and upload to the server 3, it means that the optical fiber end face loss of the optical port is too large and needs to be repaired and replaced.

[0085] See also Figure 6 , Figure 6Schematic diagram of connection between an embodiment of the present invention and a smart terminal. In this embodiment, the optical fiber full data detector 1 and the smart terminal 4 can be connected by wire or wirelessly, and the optical fiber full data detector 1 can be provided with a USB interface 114 for connecting to the smart terminal 4. Alternatively, a Bluetooth communication module 137 for connecting to the smart terminal 4 is provided on the circuit board 13, and the Bluetooth communication module 137 is respectively connected to the emitting light source 1361 and the main controller 131, and is used to communicate with the smart terminal 4. The smart terminal 4 can be, for example, a smart phone, an iPad, etc. The smart terminal 4 needs to download and install an APP used in conjunction with the optical fiber full data detector 1, and supports Bluetooth 4.0 communication rate. The Bluetooth communication module 137 must always be open to the outside for detection, and the name can be XDFC_XXXXXX, where XXXXXX is the last 3 bytes of the MAC address. It can detect the disconnection and connection of Bluetooth in real time, has a heartbeat function, and transmits the current connection status in real time. If the current mobile phone has been configured, the optical fiber full data detector 1 will connect immediately after scanning the mobile phone. The MAC address of the mobile phone can be used to check whether the mobile phone has been paired before. The optical fiber full data detector 1 saves the MAC addresses (Media Access Control or Medium Access Control address, called physical address or hardware address, used to define the location of network devices) of the mobile phones that have been connected. For example, it can save the MAC information of no less than 5 mobile phones.

[0086] After the main controller 131 receives the mobile phone APP transmission instruction through the Bluetooth communication module 137, it starts the transmission. The content of the transmission data, power and other parameters are notified to the main controller 131 by the APP instruction through the protocol. The main controller 131 first encodes the data content, and then starts sending after starting the power selection. After the sending is completed, it responds to the APP. When sending, the optical fiber full data detector 1 can preferably send the leading data first, give the receiving end a certain amount of time to wake up, and then start sending the real detection data. A check can be set for the detection data to facilitate the receiving end to check whether the data is correct. After the sending is completed, the sending result is sent to the mobile phone APP through the Bluetooth communication module 137.

[0087] The communication between the optical fiber full data detector 1 and the mobile phone APP adopts a question-and-answer mode, and all communications are actively initiated by the mobile phone APP. After the mobile phone APP is connected to the optical fiber full data detector 1, a login instruction is initiated to log in to the optical fiber full data detector 1. The main controller 131 sends the current firmware version, hardware version, error status, battery power and other information to the mobile phone APP. After the login is completed, in the idle state, the mobile phone APP sends a heartbeat instruction to the optical fiber full data detector 1 every once in a while, for example, every 10 seconds, and the optical fiber full data detector 1 responds with information such as the current error status, battery power, and current working status.

[0088] The optical fiber full data detector 1 of the present invention is mainly used to measure optical power and transmission data, wherein the optical power measurement module 135 can be provided with three optical power measurement units, namely the first optical power measurement unit 1351, the second optical power measurement unit 1352 and the third optical power measurement unit 1353, or it can be three photosensors, which can measure three optical signals at the same time. It is connected to the main controller 131 and communicates in a question-and-answer mode. The instructions mainly include setting instructions and obtaining measurement data instructions. The setting instructions are mainly used to select the wavelength, and the obtaining measurement data instructions are mainly used to read the measurement data of the first optical power measurement unit 1351, the second optical power measurement unit 1352 and the third optical power measurement unit 1353. A power supply module can be provided inside the optical power measurement module 135. Considering the low power consumption factor, the main controller 131 can control the switch of this power supply. When shutting down or not needing to collect PD data, the power supply 12 of the measurement module can be directly cut off to reduce power consumption.

[0089] The first optical power measuring unit 1351 is used to measure line loss. In the line loss measurement mode, only the measurement value of the first optical power measuring unit 1351 is used. Using the command to obtain measurement data, the optical power measuring module 135 gives three measurement values ​​of the first optical power measuring unit 1351, the second optical power measuring unit 1352 and the third optical power measuring unit 1353 at one time. Only the value of the first optical power measuring unit 1351 is taken. The second optical power measuring unit 1352 is used to measure the end face loss of the optical fiber. The second optical power measuring unit 1352 measures the light leakage loss on the side of the optical port. The power of the detection light wave sent by the transmitting light source 136 will change with the increase of service life and the length of service time. In this way, the measured end face loss data will deviate from the actual data and need to be calibrated. Therefore, the third optical power measuring unit 1353 reads the data of the end face loss calibration unit 143 installed on the calibration adapter 149 to calibrate the second optical power measuring unit 1352. When measuring the end face loss, two sets of data from the second optical power measurement unit 1352 and the third optical power measurement unit 1353 are required for addition and subtraction operations, so that the measurement result is more accurate (the calculation can be completed through the calculation module of the main controller 131 or the APP of the smart terminal 4).

[0090] The optical fiber full data detector 1 of the present invention can also enter the calibration mode through the button 112 or the APP installed in the smart terminal 4. The calibration mode is used for factory calibration. For example, the calibration mode can be entered by pressing the long button 112. After releasing it, the calibration mode can be entered by pressing the short button 112 again. If it is pressed again, it means exit. The calibration mode is to save the measurement value of the second optical power measurement unit 1352 and the third optical power measurement unit 1353. The calibration is performed once before leaving the factory, and the data is saved. It is preferred to take an average value of multiple measurements. The average value is the calibration value. The calibration value can be transmitted to the APP when the APP reads real-time data.

[0091] When it is necessary to measure line loss or end face loss, the APP installed in the smart terminal 4 should first send a startup command to allow the optical fiber full data detector 1 to start the optical power measurement module 135. After the startup is completed, the optical fiber full data detector 1 responds successfully. If an error occurs during the startup, the optical fiber full data detector 1 responds with an error code. After receiving the successful response from the optical fiber full data detector 1, the APP sends an instruction to obtain test data, for example, the measurement data can be read once every 200MS. The data content includes the error value between the first optical power measurement unit 1351, the second optical power measurement unit 1352, and the third optical power measurement unit 1353 and the second optical power measurement unit 1352. When the measurement is completed and the measurement data is no longer needed, the APP sends a shutdown command to notify the optical fiber full data detector 1 to shut down the optical power measurement module 135. In the measurement working state, if the Bluetooth communication module 137 is disconnected or the read instruction of the APP is not received within the specified time (for example, 10 seconds), the optical power measurement module 135 is powered off.

[0092] When the APP finds that there is a new version of the program on the server 3 through the firmware version in the login information, it can be downloaded to the intelligent terminal 4 (such as the mobile phone), and then the firmware of the optical fiber full data detector 1 is upgraded through the Bluetooth communication module 137. The optical fiber full data detector 1 sends the optical port code through the optical fiber line to the optical port of the connection point. After the detector on the optical port receives the activation information and the incoming code information, it is decoded by the photon tag collection disk and uploaded to the photon tag transceiver box 2. The photon tag transceiver box 2 receives the receiving point code and the corresponding optical port code and sends it to the server 3. The server 3 receives multiple groups of optical port codes and receiving optical port codes, and links the groups with the same sending optical port code together to form a route. When the mobile phone APP needs to transmit light waves, it communicates directly with the server 3. The server 3 commands the optical fiber full data detector 1 to work. The optical fiber full data detector 1 can also have its own communication module to complete the communication with the server 3. If there is no communication module, the server 3 needs to use the communication module of the mobile phone, and then connect to the optical fiber full data detector 1 through the Bluetooth communication module 137 to transmit light waves.

[0093] The present invention can realize the detection of optical fiber line and end face loss, optical fiber connection point fault detection, and optical fiber route detection; by transmitting coded detection light waves, the optical detection module installed on the optical port of the ODF frame, that is, the photon tag 5, is activated, and the light is collected in the photon tag transceiver box 2 in the cabinet top box, and two optical port code groups are uploaded to the server 3 through the communication module installed in the photon tag transceiver box 2. The server 3 forms the route of the optical port optical path by associating one of the codes with the group with the same code carried by the detection light wave; by adjusting the power of the emitted detection light wave, the photon tag is activated only when a fault occurs at the optical fiber connection point, and the optical port code of the fault point of the server 3 is uploaded through the photon tag transceiver box 2 to realize fault detection. Find; The optical fiber full data detector 1 detects the connection quality of the optical port connector and the line, records the line loss of each connection point of the optical fiber connection and the connector connection end face loss test, and automatically enters the detection data through the optical fiber full data detector 1. Finally, through the historical data graph, the degraded optical fiber line and connection point are analyzed, and maintenance is done in advance to prevent problems before they occur; the optical fiber full data detector 1 can also realize big data management after the archives of the existing machine room are digitized. When the connector fails and the optical port pops up, the paper label is photographed and the complete information is downloaded from the server 3 to confirm the position of the optical port and quickly resolve the fault; the electronic photography and identification of the paper label can also be used to efficiently complete the download and confirmation of the information of the optical port connector.
