Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of a method for checking an optical distribution frame according to an embodiment of the present invention. The method is used for checking and calibrating the accuracy of stock data of the optical distribution frame in the resource system. And, the method is performed by an intelligent terminal integrated with a 3D scanning module. As shown in fig. 1, the method comprises the steps of:
step S110: scanning a terminal panel of the optical fiber distribution frame to be checked to generate a 3D model to be checked; and extracting a plurality of characteristic values of a plurality of terminal positions in the terminal panel from the 3D model to be checked.
The optical fiber distribution frame to be checked is an optical fiber distribution frame needing field checking.
When checking, the terminal panel of the optical fiber distribution frame to be checked is scanned on site by utilizing the 3D scanning module of the intelligent terminal, then the intelligent terminal generates a 3D model to be checked according to scanning parameters, and the characteristic value of the position of each terminal is extracted from the 3D model to be checked, wherein the characteristic value refers to the image characteristic of the corresponding position in the 3D model.
Step S120: and sending the identification information of the optical fiber distribution frame to be checked and the characteristic values to a model checking module so that the model checking module can check and obtain real-time occupation information of a plurality of terminals in the terminal panel according to the identification information, the characteristic values and standard characteristic values in a model library.
The identification information is position information or model code information which can uniquely represent the optical fiber distribution frame. And, the standard feature value refers to an image feature when the corresponding terminal is in an idle state.
The intelligent terminal sends the identification information of the optical distribution frame to be checked and a plurality of characteristic values extracted after field scanning to a model checking module, the model checking module can compare the standard characteristic values corresponding to the terminal panel of the optical distribution frame to be checked stored in a model library with the received characteristic values, and real-time occupation information of the terminals corresponding to the characteristic values extracted after field scanning is determined according to the difference between the characteristic values and the standard characteristic values, namely, the terminals are determined to be in an occupied state or an idle state.
Step S130: and acquiring stock data information of the terminal panel of the optical fiber distribution frame to be checked from the resource system, and restoring stock occupation information according to the stock data information.
Wherein stock data of terminal panels of each optical distribution frame which is accessed to the network is recorded in the resource system, namely which terminals are available.
The intelligent terminal can be connected with the resource system through a wired or wireless data network, and sends a request for inquiring the stock data information of the terminal panel of the optical fiber distribution frame to be checked to the resource system so as to acquire the stock data information; then, the intelligent terminal restores the stock occupation information of the terminal panel according to the stock data information, namely restores the occupation condition according to the stock, for example, if one terminal is idle, the occupation value is 0, and if the terminal is not idle, the occupation value is 1.
In the present invention, the difference between the inventory data information in the accounting system and the occupancy of the site is checked by comparing the real-time occupancy information obtained in the foregoing steps S110 and S120 with the inventory occupancy information obtained in the step S130, and although fig. 1 only shows the case where the steps S110 to S130 are sequentially executed, the actual implementation is not limited to this, and the step S130 may be executed at any time in the execution process of the steps S110 to S120, or may be executed before the step S110.
Step S140: and receiving real-time occupation information returned by the model verification module, and feeding back terminal occupation difference data to a user according to the difference between the real-time occupation information and the stock occupation information so as to verify and calibrate the stock data information in the resource system.
The intelligent terminal compares the real-time occupation information with the stock occupation information, and if the occupation value in the real-time occupation information is inconsistent with the occupation value in the stock occupation information, the intelligent terminal indicates that the stock data information of the terminal in the resource system has a difference compared with the actual occupation condition of the site; otherwise, no difference is indicated. By feeding back the occupancy differential data to the user, it is possible to facilitate calibration of the inventory data information in the resource system so that the inventory data information in the resource system is consistent with the actual occupancy situation.
According to the checking method of the optical fiber distribution frame, a 3D scanning modeling mode is adopted to acquire the characteristic values of the on-site ODF terminal panel, and the characteristic values are compared with the standard characteristic values in the model library to automatically determine real-time occupation information of a plurality of terminals; and comparing the real-time occupation information obtained by using the 3D scanning modeling checking means with the stock occupation information restored from the stock data information in the resource system to determine the difference between the site and the stock data, and calibrating the data in the resource system according to the difference result so as to keep the occupation condition of the data in the resource system and the terminal in the site consistent. Therefore, according to the scheme of the embodiment, the data in the resource system can be automatically checked and calibrated through the feature value comparison and the consistency verification of the occupation information, so that the checking and calibrating efficiency of the optical fiber distribution frame is improved; meanwhile, compared with the scheme of photographing to determine the occupation condition of each terminal on site, the 3D model is obtained through scanning and the characteristic value is extracted, the three-dimensional image characteristics can be obtained, namely, not only plane image information but also information such as the length of the terminal can be obtained, the accuracy of determining the terminal occupation condition can be improved through comparison of the characteristic values, and therefore the data in a resource system can be calibrated conveniently and accurately.
Fig. 2 is a flowchart of a method for checking an optical distribution frame according to another embodiment of the present invention. The method is used for checking and calibrating the accuracy of stock data of the optical distribution frame in the resource system. And, the method is performed by an intelligent terminal integrated with a 3D scanning module. As shown in fig. 2, the method comprises the steps of:
step S210: before a new optical fiber distribution frame is placed in the network, a terminal panel of the new optical fiber distribution frame is scanned to generate a standard 3D model, a plurality of standard characteristic values of a plurality of terminal positions in the terminal panel of the new optical fiber distribution frame are extracted from the standard 3D model, and identification information of the new optical fiber distribution frame and the plurality of standard characteristic values are stored in a model library.
3D scanning is carried out on the terminal panel by using the intelligent terminal before the ODF of the new model is accessed to the network, and a plurality of standard characteristic values are extracted from a standard 3D model generated by scanning. Since the terminal panel of the ODF is not used at this time, the standard feature value shows the image feature when the respective terminal positions are idle. And then, the extracted standard feature values and the identification information of the new optical fiber distribution frame are correlated and stored in a model library for subsequent feature comparison.
Step S220: scanning a terminal panel of the optical fiber distribution frame to be checked to generate a 3D model to be checked; and extracting a plurality of characteristic values of a plurality of terminal positions in the terminal panel from the 3D model to be checked.
The plurality of characteristic values extracted from the 3D model to be checked obtained by field scanning are actual real-time image characteristics of the terminal panel after network access. For example, if a terminal is actually occupied, the characteristic value displayed at the corresponding position of the terminal is the characteristic of the occupied plug-in fiber.
Step S230: and sending the identification information of the optical fiber distribution frame to be checked and the characteristic values to a model checking module so that the model checking module can check and obtain real-time occupation information of a plurality of terminals in the terminal panel according to the identification information, the characteristic values and standard characteristic values in a model library.
Specifically, the intelligent terminal can send the positioning position where the current scanning is located to the model checking module as identification information, the model checking module can find a plurality of standard characteristic values of the corresponding optical fiber distribution frame in the model library by using the positioning position for comparison, and the mode does not need a user to manually input identification information such as model codes and the like to the intelligent terminal and send the identification information to the model checking module for inquiry; or the intelligent terminal can receive the identification information such as the model code input by the user and the like and send the identification information to the model checking module to accurately inquire the corresponding standard characteristic value, and the mode is favorable for accurately obtaining the standard characteristic value.
The intelligent terminal sends the multiple characteristic values extracted by field scanning and the identification information to a model checking module, and the model checking module inquires multiple standard characteristic values of multiple terminal positions corresponding to the optical fiber distribution frame to be checked in a model library according to the identification information; and comparing the queried standard characteristic values with characteristic values sent by the intelligent terminal to determine real-time occupation information of the terminal panel. Judging whether the difference between the characteristic value of the terminal position and the standard characteristic value is larger than or equal to a preset difference value or not according to any terminal position, if so, marking the occupation value corresponding to the terminal position in the real-time occupation information as a first information value; if not, marking the occupation value corresponding to the terminal position in the real-time occupation information as a second information value. In other words, if there is no obvious difference between the characteristic value of a certain terminal position and the standard characteristic value, it indicates that the characteristic value of the field is similar to the characteristic when not occupied, and at this time, the occupied value of the terminal position in the real-time occupied information is marked as a first information value, for example, ter (n) =0; if the characteristic value of a certain terminal position has obvious difference with the standard characteristic value, the characteristic value of the scene has large difference with the characteristic when not occupied, and the terminal position is considered to be not in an unoccupied state, and the occupied value of the terminal position in the real-time occupied information is marked as a second information value, for example, ter (n) =1.
And after the model verification module obtains the real-time occupation information through verification, the real-time occupation information is fed back to the intelligent terminal so as to be used for the intelligent terminal to carry out consistency verification on the data in the field and the resource system.
Step S240: and acquiring stock data information of the terminal panel of the optical fiber distribution frame to be checked from the resource system, and restoring stock occupation information according to the stock data information.
The condition of available terminals, i.e. unoccupied terminals, in the terminal panel of each fiber optic distribution frame, is recorded in the resource system, and is herein collectively referred to as stock data information.
Specifically, the intelligent terminal may also query the stock data information of the terminal panel of the optical fiber distribution frame to be checked by sending a positioning position or a model code to the resource system, and the intelligent terminal may restore the stock occupation information of the terminal panel based on the stock data information acquired from the resource system, for any terminal position, if the stock data information indicates that the terminal position is occupied, the occupation value corresponding to the terminal position in the stock occupation information is identified as a first information value, for example, xTer (n) =1; if the stock data information shows that the terminal position is not occupied, the occupancy value corresponding to the terminal position in the stock occupancy information is identified as a second information value, for example, xTer (n) =0.
In some optional embodiments of the present invention, a terminal layout diagram may be generated according to the occupation value of each terminal position, on which different occupation values are marked with different marks, so as to intuitively correspond to terminal occupation conditions of stock data information in the resource system.
Step S250: receiving real-time occupation information returned by the model checking module, comparing the consistency of the real-time occupation information with the stock occupation information, and screening out a difference terminal with inconsistent occupation values in the real-time occupation information and the stock occupation information; the terminal information of the differential terminal is fed back to the user to verify and calibrate the stock data information in the resource system.
On one hand, the intelligent terminal can obtain the actual occupation situation of a plurality of terminals in the terminal panel of the optical fiber distribution frame to be checked by receiving the real-time occupation information returned by the model checking module, and on the other hand, the intelligent terminal obtains the stock occupation information according to the stock data information reduction in the resource system, and can obtain the recorded occupation situation of a plurality of terminals in the terminal panel of the optical fiber distribution frame to be checked. The intelligent terminal compares the occupation value of the terminal position in the real-time occupation information with the occupation value of the terminal position in the stock occupation information by comparing the real-time occupation information with the stock occupation information, if the real-time occupation information is consistent with the stock occupation information, the intelligent terminal indicates whether the terminal position is occupied or not recorded in the resource system is the same as the terminal position displayed in the actual occupation situation, namely the stock of the terminal position recorded in the resource system is accurate; otherwise, if the two are inconsistent, it indicates that whether the terminal position recorded in the resource system is occupied is different from the situation that whether the terminal position displayed in the actual occupied situation is occupied, that is, the stock of the terminal position recorded in the resource system is deviated, that is, the terminal corresponding to the terminal position is a differential terminal. And feeding back the terminal information of the differential terminal to the user, for example, displaying on the intelligent terminal, from which the user can modify the stock data information in the resource system.
For example, if a terminal position has an occupation value Ter (n) =1 in the real-time occupation information, i.e. the terminal is occupied, and an occupation value Ter (n) =0 in the storage occupation information, i.e. the terminal is idle, and it is obvious that there is a difference between the two, the storage of the terminal position recorded in the resource system is considered to be different from the actual one, the terminal information of the different terminal, such as the terminal position, is recorded as a difference terminal, and the terminal information of the difference terminal, such as the terminal position, is displayed on the intelligent terminal, and the user can delete the storage of the terminal position in the resource system according to the terminal position.
In some optional embodiments of the present invention, after the terminal panel of the optical fiber distribution frame to be checked is scanned to generate a 3D model to be checked, a line projection view of the terminal panel is superimposed in the 3D model to be checked, and when the terminal difference data is fed back to the user, the terminal difference data is marked in the line projection view according to the difference between the real-time occupancy information and the stock occupancy information, that is, the difference is intuitively displayed in the line projection view of the terminal panel, so that the user can accurately check and calibrate.
According to the checking method of the optical fiber distribution frame, the 3D scanning module of the intelligent terminal is used for carrying out scanning modeling on the terminal panel, model codes and characteristic information are transmitted to the model checking module, the model checking module compares the data with standard characteristics of the same model which are preset in the model library, and the distribution structure of occupied and idle terminals is checked and pushed to the intelligent terminal. The intelligent terminal restores the distribution structure of the occupied and idle terminals from the stock data information of the resource system, compares the two, and feeds the difference back to the user for rectifying the stock data information in the resource system.

Fig. 4 is a schematic structural diagram of a checking system for an optical distribution frame according to an embodiment of the present invention.
As shown in fig. 4, the system includes:
an intelligent terminal 410 provided with a checking device of the optical distribution frame according to the above device embodiment, a model checking module 420, a resource system 430 and a model library 440;
wherein, a 3D scanning module is integrated in the intelligent terminal 410, and the intelligent terminal 410 is connected with the model checking module 420 and the resource system 430; and, the model verification module 420 is coupled to the model library 440.
The model verification module is connected with the model library and the intelligent terminal and is mainly used for comparing and verifying the characteristic value of the 3D model to be checked with the standard characteristic value.
The method comprises the steps that a model verification module obtains a model code of an optical fiber distribution frame to be checked from an intelligent terminal, invokes a standard characteristic value of the model code from a model library, compares the standard characteristic value with a characteristic value sent by the intelligent terminal, wherein terminal occupation states displayed by the invoked standard characteristic value in the model library are all idle states, no jump fiber connection is defaulted, and for any terminal, if the characteristic value has obvious difference with the standard characteristic value, the terminal is proved to be inserted into a tail fiber, and the terminal is occupied; otherwise, the device is idle.
If the characteristic value of a certain terminal position in a 3D model of a certain type of optical fiber distribution frame has no obvious difference with the standard characteristic value, the identification occupied value Ter (n) =0, if the characteristic value of the terminal position has obvious difference with the standard characteristic value, the identification occupied value Ter (n) =1, and the model verification module pushes the data to the intelligent terminal for consistency verification of the field and the resource system data.
The intelligent terminal performs 3D modeling on scanning parameters obtained by scanning the terminal panel according to the 3D scanning module and performs feature extraction, and pushes model codes input by a user on the intelligent terminal and extracted feature values to the model checking module.
Specifically, the 3D scan module is integrated onto the intelligent terminal, and the types of 3D scan modules that can be integrated into the intelligent terminal (such as a mobile phone) are more, but two technologies of the main stream are 3D structure and ToF.
3D Structured Light (Structured Light): the basic principle of the 3D structured light technology is that a near infrared laser is integrated, light rays with certain structural characteristics are projected onto a photographed object, and then are collected by a special infrared camera. The light rays with a certain structure can acquire different image phase information due to different depth areas of a shot object, and then the change of the structure is converted into the depth information through an operation unit, so that a three-dimensional structure is obtained.
ToF (Time Of Flight): toF is one of the schemes for 3D depth cameras. ToF ranging is divided into two types, namely single-point ranging and multi-point ranging, wherein multi-point ranging is generally used on a mobile phone. The principle of multi-point ranging is similar to that of single-point ranging of pulse, but its light receiving device is CCD, i.e. a charged-held photodiode array, and has integral characteristic to light response. The basic principle is that a laser source emits laser with a certain view angle, wherein the laser time length is dt (from t1 to t 2), each pixel of the CCD utilizes two synchronous trigger switches S1 (t 1 to t 2) and S2 (t 2 to t2+dt) to control the period of time for a charge holding element of each pixel to collect reflected light intensity, and responses C1 and C2 are obtained. The distance l=0.5×c×dt×c2/(c1+c2) of the object from each pixel, where c is the speed of light (this formula can remove the effect of the difference in the reflective characteristics of the reflectors on the distance measurement). In short, the processed light is emitted, reflected back after hitting an object, and the back and forth time is captured, so that the distance to the object can be rapidly and accurately calculated due to the known light speed and the wavelength of the modulated light.
The terminal panel of the optical fiber distribution frame can be scanned by using the intelligent terminal with the 3D scanning module, and scanning parameters are sent to the intelligent terminal to draw a 3D model of the terminal panel.
And the intelligent terminal is connected with the resource system through a wireless data network, can find the stock data information of the terminal panel of the optical distribution frame to be checked from the resource system in a position positioning and manual searching mode by a user, and generates a terminal layout diagram.
