Description of the Invention: [Technical Field] The present invention relates to a passive optical network autonomous monitoring method, in particular to a built-in optical monitoring function module for central office equipment and remote equipment, coupled with passive optical fiber The network management device and the remote data processing device collect and analyze the monitoring data to determine whether the passive optical network has network anomalies and abnormal locations, and assist the network maintenance personnel to quickly eliminate network obstacles, and Prevent network barriers from happening in the first place to achieve the goal of passive fiber network autonomous monitoring methods. [Prior Art] In response to the large demand for communication services triggered by the Internet, various transmission technologies, transmission media and network architectures have been proposed, hoping to meet the needs of users with the most economic benefits. The need for service bandwidth. Among them, the passive optical fiber network has the advantages of high frequency bandwidth, no interference and large coverage (4), and is the most important access network solution for providing broadband services for users at present and in the future. The passive optical network is a point-to-multipoint network architecture. It is used by a central office equipment—the optical fiber line is connected to the optical splitter near the user#. The secret connection is more than four (4), which can be called low network construction and dimension=cost effect. . Since passive optical networks use optical splitters that consume a lot of optical power, such passive optical components also make it difficult to monitor the network. For the monitoring of passive optical networks, the conventional methods are mainly based on the optical fiber distribution network of passive optical networks, including: I. Monitoring method using Optical Time Domain Reflectometer (〇TDR), due to In the passive optical network, the optical splitter is used to achieve the point-to-multipoint network architecture, but this also causes the reflection signal of the optical time domain reflector to be superimposed on the reflected path of all the different routes from 201216643. , and the reflected signal of any divergent route cannot be identified. In order to solve the problem of identifying the reflected signal, there are the following methods: (1) In the difference of the optical splitter, the active identification component is installed at the end. This requires the interaction between the communication network and the control computer installed at the computer terminal. The complexity of the monitoring system also interferes with the communication network. (2) Adding the residual length fiber and the reflective component at the end of the divergent routing of the optical splitter as the identification component. Due to the different lengths of the network divergence route, there is uncertainty in the actual planning and construction. difficult. In addition, due to the dynamic range of the optical time domain reflector (Dynamic is called ... and the Event Dead Zone), the actual monitoring target is difficult to achieve. 2. Add passive identification components at the end of the divergent routing of the optical splitter. Reflecting different monitoring wavelengths on different bifurcation routes, although using a spectrum analyzer with a control computer to overcome the limitations of the optical time domain reflector, since the identification element provides reflection for a particular monitoring light wavelength, a special design is required, high The cost will be expected 'and the customary method still needs to insert the multiplexed components in the communication network, which will also cause interference to the network construction. For the detection of optical transmitters and optical transceivers, the conventional methods are: 1. The optical transceivers of the fiber-optic cable network headend (HEADEND) and the optical transceivers of the distribution terminal (HUB) are respectively equipped with monitoring transponder components, and the public telephone network is used to transmit back monitoring information, which can be used in the monitoring center. Master the obstacles of the network light transmitter and optical transceiver. However, the overall monitoring system is highly complex and uses the public telephone network to transmit monitoring signals. To increase the uncertainty and cost of maintenance. It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved. The inventors of this case, in view of the shortcomings derived from the above-mentioned conventional methods,亟思进行201216643 . Improvement and innovation, and after years of painstaking research, finally successfully developed this passive optical fiber network autonomous monitoring method. [ SUMMARY OF THE INVENTION The object of the present invention is to provide a passive optical network autonomous monitoring method The system uses the built-in equipment and the remote device to build the optical monitoring function module, and cooperates with the passive optical network network management equipment and the remote data processing equipment to collect and analyze the monitoring data, and uses the passive optical network to transmit. Channels are used to transmit monitoring data. The entire monitoring method fully utilizes passive fiber-optic network equipment and remote data processing equipment to implement the operation without providing an additional monitoring system to provide a stable, reliable and no external environmental impact. Monitoring method to achieve the goal of passive fiber network autonomous monitoring methods The passive optical network autonomous monitoring method for achieving the above object aims to continuously monitor and process and record the transmitted optical power of the device by using the built-in optical monitoring function module of the passive optical fiber network. Level and received optical power level. Passive optical network network management equipment uses the existing transmission channel inside the network to periodically read the monitoring data from the central office equipment and the remote equipment to establish the user-specific routing optical power level. The data and the continuously updated user-specific route optical power level data. The remote data processing device periodically reads the optical power level reference from the network management device according to the user identification code corresponding to the link between the central office device and the remote device link. The data and the current latest optical power level data, and the implementation of the data comparison and analysis to determine whether the network is abnormal or impending anomalies, and notify the network maintenance management personnel to carry out the necessary disposal to ensure the network The quality of the road service.
