Description

Intelligent optical distribution network line card and optical distribution network equipment

Technical field

The present application relates to, but is not limited to, the field of communications, and in particular, to an Intelligent Optical Distribution Network (IODN) line card and an Optical Distribution Network (ODN) device.

Background technique

The Intelligent Optical Distribution Network (IODN) device introduces electronic tag technology to optical fiber and fiber optic handover equipment ports to realize automation, intelligence, and process management of optical distribution network resources.

At present, there are two common design methods for intelligent optical distribution network devices: Method 1. Remove all or part of the upper cover of the wiring panel of the conventional optical distribution network device, and then install a new intelligent distribution panel cover. Method 2: hang an intelligent management module in front of the wiring panel of the conventional optical distribution network device. The intelligent distribution panel or intelligent management module is composed of a structural member and a printed circuit board (PCB). The printed circuit board realizes the fiber optic adapter port indication of the wiring panel body and the electronic tag identification function of the optical fiber jumper connector. The electronic tag adopts a contact electronic tag (Electronic Identity, eID for short) or a non-contact radio frequency identification (Radio). Frequency Identification (referred to as RFID) electronic tag two ways.

The smart cover structural member is customized according to the outer dimensions of the wiring panel body of the conventional optical distribution network device, and generally adopts a non-metal material and needs to be opened. The appearance of the printed circuit board is also customized according to the shape of the upper cover structure. The top cover of various brands and models of wiring panels has different outer dimensions, so it is necessary to design various corresponding shapes of intelligent distribution panel covers according to the upper cover of various brands and models of wiring panels. And open the port indicator holes of different spacing on the intelligent distribution panel cover. In this way, it is easy to cause waste of manpower and resources, and is not conducive to the unified management of optical distribution network operators.

If the electronic tag is fixedly mounted on the fiber jumper connector, the angle of the fiber adapter installation direction of each type of the wiring plate body cannot be adjusted. Although the eID electronic tag is installed on the fiber jumper connector with a soft jumper, it can be adapted to insert the fiber adapter in different directions. However, in the application, a two-step operation step is required: Step one, the fiber jumper is used. The connector is inserted into the fiber adapter; in step two, the eID electronic tag on the soft jumper is inserted into the electronic tag socket. The above-mentioned two-step insertion implementation method of the smart ODN using the cord connection does not conform to the implementation habit of the ordinary ODN which only needs to be inserted in the first step.

It can be seen that the fiber optic adapters of various brands and models of the related art have different installation direction angles, and the spacing between the fiber adapters is different, that is, the implementation of the intelligent ODN line card, whether by using eID or RFID electronic tags, Inevitably, it is necessary to customize different intelligent ODN line card structure shells according to the structure types of different fiber distribution panels, and design different smart ODN line card PCB appearances. In the related art, the intelligent ODN line card hardware circuit and software of a single intelligent ODN equipment supplier are identical, and the difference is only in the structural appearance. The existing optical fiber distribution panel has hundreds of different types of structures. The use of related technologies has resulted in a large waste of manpower and material resources, and it is impossible to fully implement intelligent ODN technology.

The present application will be further described below in conjunction with the accompanying drawings and specific embodiments of the present embodiments.

As shown in FIG. 3, the intelligent ODN line card system involved in the optional embodiment is a box body, including a common K optical fiber connector with an RFID electronic tag, a casing body, and a casing body. The intelligent ODN line card unique to this application. The box body is installed in front of the fiber-optic wiring board body, and the box body corresponds to the position of the fiber-optic connector inserted outside the fiber-optic adapter of the fiber-optic wiring board body; the casing body and the intelligent ODN line card length are equal to the longest existing optical fiber. The length of the wiring panel body; wherein the K RFID electronic tags are respectively fixedly attached to the K optical fiber connectors, or are an integrated structure, which is different from the soft jumper connection method. The intelligent ODN line card includes an RFID read/write module, an M*N antenna array, a K port indication module, and an uplink interface.

It should be noted that the M*N antenna array in the optional embodiment is an antenna combination of M rows and N columns, M is greater than or equal to 1, and N is greater than or equal to the number K of the distribution disk optical fiber adapter ports. The cable body is a 12-port fiber adapter disk body, and the antenna array can be selected as 2*28=56 antenna combinations as an example. The optional embodiment is described in detail.

The K port indicating module is adjacent to the front panel of the box body, and the front panel of the box body has a plurality of openings, the number of openings is larger than the number K of the fiber trays of the wiring board body, and each opening corresponds to one port indicator. The port indicator and aperture arrangement cover all possible fiber adapter locations. If the fiber distribution panel is a 12-port fiber adapter disk, the port indicator module can alternatively be selected as a combination of 28 port indicators, wherein the port indicator can be an LED indicator, a light bulb, or other light-emitting component.

The uplink interface completes the communication functions of the intelligent ODN line card and the main control unit in the intelligent ODN device, including but not limited to conforming to the Zigbee, Bluetooth, WIFI, RS485, RS232, and I2C standards.

Based on the function of each part of the above ODN line card, after the smart ODN line card is powered on, the RFID read/write module first scans the RFID electronic tag through the antenna array. According to the RFID anti-collision algorithm, each antenna returns an electronic tag ID number and RF parameters to the RFID read/write module. The RFID read/write module runs an adaptive port program, and obtains the spacing and direction parameters of the electronic tag through a training algorithm. The RFID read/write module selects K antennas in the antenna array and K port indicators in the port indication module by using the spacing and direction parameters of the electronic tags and calculating the RF parameters.

The RFID read/write module of the intelligent ODN line card scans the electronic tag through the M*N antenna array. 7 is a schematic diagram of a training algorithm according to an alternative embodiment of the present application. As shown in FIG. 7, for example, an RFID read/write module passes an antenna ANT[1,1], ANT[1,2 according to an RFID anti-collision algorithm. ], ANT[2,1] scans to the electronic tag TAG[1] and three sets of RF parameters. The RFID read/write module similarly scans the electronic tag TAG[2] and the three sets of RF parameters through the antennas ANT[1,3], ANT[1,4], ANT[2,3], through the antenna ANT[i,j] ANT[i, j+1], ANT[i+1, j] scans to the electronic tag TAG[i] and three sets of RF parameters. The RF parameters include radio frequency parameters such as power and time returned by the air interface. The RFID read/write module runs an adaptive port program, and through the training algorithm, obtains the horizontal spacing parameter X and the direction parameter Degree of the electronic tag. The following calculation formula [Ant] is the return parameter matrix of the RFID air interface antenna, and [Mask] is the label matrix scanned by the RFID read/write module, where 1 indicates that the position antenna is scanned to the electronic tag, and 0 indicates that the position antenna is not scanned to the electronic label.

The electronic tag parameter Para[i,j] obtained by the above calculation formula, including the horizontal spacing parameter x[i,j] of each electronic tag, and the average of the RFID read/write module to obtain the average horizontal spacing of the intelligent ODN line card electronic label X . According to the average horizontal spacing X, K LEDs are selected among 30 LEDs, and LED serial numbers such as LED[1], LED[3], ..., LED[K] are recorded. The weight of each antenna parameter is estimated using the formula w[i,j]=a×p[i,j]-b×t[i,j], Maximum Likelihood, where a and b are The set constant. The RFID read/write module obtains the most suitable antenna number K and the horizontal deflection angle degree of the fiber adapter by comparing the return power p[i, j] and the return time t[i, j]. A preferred comparison operation method is a multiple sampling filtering method. For example, sampling n times weight (weight), calculate the average weight according to the following formula:

Where w[i,j]max is the sampled maximum weight value; w[i,j]min is the sampled minimum weight value; w[i,j]s is the sampled other weight value, and is sampled n -2 times. This multi-sample filtering method can filter out abnormal distortion of sampled data due to environmental and sudden factors. In actual operation, according to the actual conditions, the sampling number n can be selected by itself, the sampling operation time, the system power consumption, and the accuracy of the calculation result are balanced. The RFID reading and writing module tells the main control unit of the intelligent ODN device through the uplink interface to select the K antenna serial number and the K port indicator serial number to complete the adaptive optical port software flow.

Select one of the intelligent ODN line cards in each of the three types of ODN chassis, and insert the fiber optic connector with the RFID electronic tag to run the above-mentioned self-adaptation of the present application. The software configuration file should be generated by the fiber port software. According to the algorithm of the alternative embodiment, the selected ODN line card of the adaptive fiber port needs to insert at least two tight fiber connectors to calculate the average horizontal spacing X. The intelligent ODN line card uploads the software configuration file to the intelligent ODN main control unit through the uplink interface. Then, the intelligent ODN main control unit sends the software configuration file to the smart ODN line card of the same structure type through the uplink interface.
