Abstract

Provided are an intelligent optical distribution network (iODN) line card and an optical distribution network (ODN) equipment. The iODN line card uses an antenna array to scan an RFID electronic tag on an optical connector to obtain an identifier and a radio frequency (RF) parameter of the RFID electronic tag. A port indicator with a number corresponding to the optical connector is then selected according to the identifier and RF parameter of the RFID electronic tag. A serial number of a selected antenna and a serial number of the port indicator are then reported. By reporting the serial numbers of the selected antenna and port indicator, other line cards are informed of the serial numbers so that a single type of iODN line card can be made compatible with every existing type of optical fiber tray. The invention solves the technical issue in which different IODN line card structures and casings must be customized to suit different structural forms of general optical fiber trays.

Description

智能光分配网络线卡及光分配网络设备Intelligent optical distribution network line card and optical distribution network equipment 技术领域Technical field
本申请涉及但不限于通信领域,尤其涉及一种智能光分配网络(IODN,Intelligent Optical Distribution Network)线卡及光分配网络(ODN,Optical Distribution Network)设备。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.
背景技术Background technique
智能光分配网络(Intelligent Optical Distribution Network,简称为IODN)设备通过对光纤和光纤交接设备端口引入电子标签技术,实现对光分配网络资源的自动化、智能化、流程化管理。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.
目前,智能光分配网络设备的常见设计方法有以下两种:方法一、将传统光分配网络设备的配线盘体的上盖板全部或者部分去除,然后安装上新的智能配线盘盖板;方法二、在传统光分配网络设备的配线盘体的前面挂一个智能管理模块。智能配线盘盖板或智能管理模块由结构件和印制电路板(Printed Circuit Board,简称为PCB)组成。印制电路板实现对配线盘体的光纤适配器端口指示和光纤跳线连接器的电子标签识别功能,电子标签采用接触式电子标签(Electronic Identity,简称为eID)或者非接触式射频识别(Radio Frequency Identification,简称为RFID)电子标签两种方式。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.
智能盖板结构件是根据传统光分配网络设备的配线盘体的外型尺寸定制的,一般采用非金属材料,需要开模。印制电路板的外型也是根据上盖结构件外型定制的。各种品牌和型号的配线盘体的上盖板外形尺寸各不相同,因而需要根据各种品牌和型号的配线盘体的上盖板设计各种对应形状的智能配线盘盖板,并在智能配线盘盖板上开不同间距的端口指示灯孔。这样,容易造成人力和资源的浪费,也不利于光分配网络运营者的统一管理。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.
采用外挂智能管理模块的方法,如果在光纤跳线连接器上固定安装电子标签,不能适应各种型号配线盘体的光纤适配器安装方向角度不同。虽然在光纤跳线连接器上采用软跳线安装eID电子标签,可以适应插入不同方向角度的光纤适配器,但是在应用时,需要两步操作步骤:步骤一,将光纤跳线 连接器插入光纤适配器;步骤二,将软跳线上的eID电子标签插入电子标签插座。上述采用软线连接的智能ODN两步插入实施方法与普通ODN只需要第一步插入的实施方式习惯不符合。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.
可见,相关技术中的各种品牌和型号的光纤配线盘体的光纤适配器安装方向角度不同,光纤适配器之间间距不同,即智能ODN线卡实施,不管是采用eID还是RFID电子标签的方式,都不可避免地遇到需要根据不同光纤配线盘体的结构类型定制不同智能ODN线卡结构外壳,和设计不同智能ODN线卡PCB外型的问题。相关技术中,单一智能ODN设备供应厂家的智能ODN线卡硬件电路和软件完全相同,仅仅区别在结构外型不同。而现存的光纤配线盘体有成百上千种结构类型,采用相关技术造成了人力物力大量浪费,根本无法全面推行智能ODN技术。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.
针对相关技术中对于不同结构的普通光纤配线盘体需要根据不同光纤配线盘体结构类型定制不同的智能ODN线卡结构外壳的问题,目前尚未存在有效的解决方案。In view of the problem that the conventional optical fiber distribution panel body of different structures needs to be customized according to different fiber distribution panel structure types in the related art, there is no effective solution at present.

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.
需要说明的是,本可选实施例中的M*N天线阵列为M行N列的天线组合,M大于或等于1,N大于或等于配线盘体光纤适配器端口数K,下面以光纤配线盘体为12端口光纤适配器盘体,天线阵列可以选取为2*28=56个天线组合为例,对本可选实施例进行详细说明。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.
K端口指示模块靠近盒体外壳前面板,盒体外壳前面板有多个开孔,开孔数大于配线盘体光纤适配器端口数K,每个开孔对应一个端口指示器。端口指示器和开孔排列覆盖所有可能的光纤适配器位置。如果光纤配线盘体为12端口光纤适配器盘体,则可选地,端口指示模块可以选取为28个端口指示器组合,其中,端口指示器可以为LED指示灯、灯泡,或者其他发光元件。 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.

基于上述ODN线卡中每个部分的功能,在智能ODN线卡上电启动后,RFID读写模块首先通过天线阵列扫描RFID电子标签。根据RFID防碰撞算法,每个天线返回一个电子标签ID号和RF参数给RFID读写模块。RFID读写模块运行自适应端口程序,通过训练(Training)算法,得到电子标签的间距和方向参数。RFID读写模块通过电子标签的间距和方向参数,并且计算RF参数,在天线阵列中选出K个天线,在端口指示模块中选出K个端口指示器。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.

以12端口的配线盘体为例,该训练算法实施流程为:考虑到避免人眼直视损害,该光纤盘体为12个倾斜的光纤适配器和对应的24个光纤连接器。因为本可选实施例中外侧光纤连接器与所附着的RFID电子标签是固定位置连接关系,所以12个RFID电子标签相对与智能ODN线卡是倾斜相同的角度。而智能ODN线卡的56个天线和线卡是平行关系,可推导出56个天线和12个RFID电子标签也是有相同的倾斜角度关系。ODN机箱上电前,先选取一块智能ODN线卡,在12个光纤适配器外侧插满12个光纤连接器,每个光纤连接器上已预先绑定RFID电子标签。Taking a 12-port wiring panel as an example, the training algorithm is implemented in such a manner that the optical fiber disk is 12 inclined fiber adapters and corresponding 24 fiber connectors in consideration of avoiding direct eye damage. Because the outer fiber connector in the alternative embodiment is in a fixed position connection relationship with the attached RFID tag, the 12 RFID tags are inclined at the same angle as the smart ODN line card. The 56 antennas and line cards of the intelligent ODN line card are in a parallel relationship, and it can be inferred that 56 antennas and 12 RFID tags have the same tilt angle relationship.

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.

通过上述计算公式得到的电子标签参数Para[i,j],其中包括每个电子标签水平间距参数x[i,j],RFID读写模块求平均值得到智能ODN线卡电子标签平均水平间距X。根据平均水平间距X在30个LED中选取K个LED,并记录LED序号,比如LED[1],LED[3],……,LED[K]。采用公式w[i,j]=a×p[i,j]-b×t[i,j],最大似然(Maximum Likelihood)估计每个天线参数的权重(Weight),其中a和b为设定的常量。RFID读写模块通过返回功率p[i,j]和返回时间t[i,j]比较运算得到最适合的天线序号K和光纤适配器的水平偏转角度degree。一种较优的比较运算方法是多次采样滤波方法。比如采样n次权重(Weight),根据下式计算平均权重: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:
Figure PCTCN2016089651-appb-000002
Figure PCTCN2016089651-appb-000002
其中,w[i,j]max为采样到的最大权重值;w[i,j]min为采样到的最小权重值;w[i,j]s为采样到的其他权重值,共采样n-2次。通过这种多次采样滤波方法可以过滤掉因为环境和突发因素引起的采样数据异常失真。实际操作时,根据实际条件可自行选择采样次数n,均衡采样运算时间、系统功耗,和计算结果准确性。RFID读写模块把选出的K个天线序号和K个端口指示器序号通过上联接口告诉智能ODN设备的主控单元,完成自适应光纤端口软件流程。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.
