Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical distribution network, in particular to an optical fiber port management device and an optical fiber port management system. BACKGROUND

[0002] Since the splitters and fusion plates on the optical distribution network all use passive devices, there is a lack of effective management means for the management of optical fiber port state and optical routing information. The current management method mainly uses manual paper label recording management, that is, a paper label containing attribute and position information is pasted at the position of the optical fiber end of each port. The biggest defect of this method is that the label is pasted manually and is prone to errors. Moreover, it is difficult to maintain the information of the corresponding port after the label falls off or is damaged. In addition, the label information cannot be strongly bound with the background data, which may cause the problem of inconsistent accounts and records, and the real-time state of the port cannot be collected.

[0003] In recent years, many manufacturers in the related technology have also proposed some intelligent management methods for ODN (Optical Distribution Network). One of the methods is to deploy passive RFID electronic tags at the port and optical fiber terminal of the label. The label information of the port and the optical fiber terminal is read one by one by an external handheld device, and information binding, association and attribute addition are performed. Finally, the information is uploaded to the asset management platform. Although this method solves the problem of digital pairing of fiber cores and ports, the efficiency of binding relationship input is still low, and the optical fiber plugging state cannot be monitored.

[0004] Therefore, it is necessary to design a new optical fiber port management device and an optical fiber port management system to overcome the above problems. SUMMARY

[0026] In order to make the technical solutions in the embodiments of the present application clearer, the accompanying drawings needed in the embodiment description will be briefly introduced. Obviously, the accompanying drawings in the following description only show some embodiments of the present application, and other drawings can be obtained by those skilled in the art without any creative effort.

[0027] The embodiments of the present application provide an optical fiber port management device and an optical fiber port management system, which can solve the technical problems of low entry efficiency and inability to monitor the optical fiber plugging state in the related art.

[0028] Referring to Figure 1 and Figure 2As shown in the figure, the optical fiber port management device provided by the embodiment of the application comprises: a plurality of electronic tags 1, which are used to be installed on optical fiber connectors; and an electronic tag collection disc 2, which is provided with a plurality of analog switches, each of which is electrically connected with an induction antenna 3, and the electronic tag collection disc 2 is further provided with a micro control circuit, which is electrically connected with the plurality of analog switches; and the micro control circuit is used to control the analog switches in time, so that the induction antenna 3 is gated and the identity information of the electronic tag 1 is collected.

[0029] Referring to Figure 1 In the embodiment, the electronic tag 1 is installed on the optical fiber connector when in use, and one electronic tag 1 is arranged on each optical fiber connector, which is used to uniquely identify the fiber core resource information. One row of induction antennas 3 is arranged on each electronic tag collection disc 2, and the induction antenna 3 in the embodiment is a near-field induction antenna 3. The induction antenna 3 corresponds to the electronic tag 1 one by one, and each induction antenna 3 is electrically connected with an independent analog switch, so that the micro control circuit can control the independent analog switch, and further control the induction antenna 3 electrically connected with the analog switch to be gated. Figure 1 N independent analog switches are shown, which are respectively arranged near N optical fiber ports.

[0030] In the embodiment, a plurality of analog switches are arranged on the electronic tag collection disc 2, and each analog switch is electrically connected with a corresponding induction antenna 3. The micro control circuit is electrically connected with each analog switch through different output ports, can control the gating and disconnection of the analog switch, and can independently control any analog switch to be opened or closed in time, so as to control the gating state of any induction antenna 3. When the channel of the induction antenna 3 is gated, the micro control circuit can control the corresponding induction antenna 3 to collect the identity information of the electronic tag 1 coupled at the corresponding channel, and can efficiently collect information. At the same time, if the identity information of the electronic tag 1 is not collected during the gating of the corresponding channel, it indicates that the optical fiber connector is not inserted into the port, so that the optical fiber plug state can be identified, and the technical problems of low recording efficiency and inability to monitor the optical fiber plug state in the related art are solved.

[0031] Further, in an embodiment, the electronic tag collection disc 2 is further provided with a radio frequency processing circuit, which is electrically connected with the micro control circuit and the analog switch. Referring to Figure 3As shown, the micro control circuit includes a synchronous communication serial port, and the micro control circuit is connected with the radio frequency processing circuit through the synchronous communication serial port (SPI). On one hand, the synchronous communication serial port is used for configuring the working state of the radio frequency processing circuit, and on the other hand, the synchronous communication serial port is used for triggering the radio frequency processing circuit to search and read the information of the electronic tag 1 in the vicinity and return the information to the micro control circuit. The radio frequency processing circuit is connected with the common end of the N independent analog switches through the internal impedance matching circuit. When the corresponding inductive antenna 3 channel is selected, the micro control circuit collects the identity information of the electronic tag 1 coupled at the corresponding channel by controlling and accessing the radio frequency processing circuit. The micro control circuit specifies a fixed storage area to record the identity information of the electronic tag 1 identified by the corresponding inductive antenna 3 channel.

[0032] Referring to Figure 1 As shown, preferably, the electronic tag collection disc 2 is further provided with a tuning circuit, and each of the analog switches is electrically connected to the inductive antenna 3 through an independent tuning circuit. In the embodiment, the open or closed contacts of the N independent analog switches are respectively connected with the tuning circuits of the N inductive antennas 3, and the tuning circuits of the inductive antennas 3 are connected with the N printed board near-field inductive antennas 3 at the corresponding ports.

[0033] Further, in an embodiment, the micro control circuit includes a micro controller and a decoder circuit, and the micro controller is electrically connected to the analog switches through the decoder circuit. Referring to Figure 3 As shown, the 16 general input and output ports of the micro controller are respectively connected with the switch direction control pins of the analog switches, and are used for controlling the selection and disconnection of the analog switches. In the collection process, only one analog switch channel is in the selected state, and when the channel is selected, the micro controller can quickly collect the identity information of the electronic tag 1 at the channel, and store the collected identity information and the channel number in the storage area of the micro controller. If the micro controller does not collect the information of the electronic tag 1 during the selection of the corresponding channel, the content of the storage area of the corresponding channel number is cleared or set. When the input and output pin resources of the micro controller are limited, another implementation form of the connection between the micro controller and the analog switch can be that the micro controller expands the required input and output pin resources through the decoder circuit to control the required analog switch. The cost of this implementation form is the lowest. Of course, when the input and output pin resources of the micro controller are not limited, the micro controller can also be directly connected to the analog switch.

[0034] Referring to Figure 1 As shown, in some embodiments, the electronic tag collection disc 2 is further provided with an external interface circuit, and the external interface circuit is electrically connected with the micro control circuit. In the embodiment, the external interface circuit is used for providing the power supply required by the electronic tag collection disc 2, and meanwhile, the external device can obtain the information of the electronic tag 1 corresponding to each channel of the electronic tag collection disc 2 through the corresponding external interface of the external interface circuit.

[0035] In some optional embodiments, the external interface circuit includes an external interface and a bus driver, and the external interface is electrically connected to the micro control circuit through the bus driver. Referring to Figure 3 As shown, in the embodiment, the bus driver can be an RS485 bus driver (of course, other types of bus drivers can also be used), the micro controller can be connected to the RS485 bus driver through an asynchronous communication serial port, and the bus side signal of the RS485 bus driver is connected to the external interface (for example, a mini connector) through a corresponding matching and surge protection circuit. The external data collector can obtain the content of the storage area of the micro controller through the RS485 communication interface. At the same time, the electronic tag collection disc 2 can obtain the required power through the external interface.

[0036] Further, in an embodiment, the micro control circuit has a Bluetooth communication module, and the Bluetooth communication module is used for wireless connection communication with the handheld terminal 5. Referring to Figure 4 As shown, another form of information interaction between the micro controller and the external is that the micro controller can select a radio frequency SoC chip with Bluetooth communication function, and the micro controller performs wireless connection communication with the external handheld terminal 5 through the internal Bluetooth function of the micro controller.

[0037] Preferably, referring to Figure 1 As shown, the electronic tag collection disc 2 is also provided with an indicator light 4, and the indicator light 4 is electrically connected to the micro control circuit. In the embodiment, the GPIO interface of the micro controller is connected to the indicator light 4 on the electronic tag collection disc 2. Each electronic tag collection disc 2 has a unique address information, which is associated and bound with the physical position of the electronic tag collection disc 2. When the physical position of the corresponding electronic tag collection disc 2 needs to be located, the address of the collection disc can be sent to the handheld terminal 5 to indicate the light, and the indicator light 4 of the corresponding electronic tag 1 collection disc is lit, so as to realize the rapid positioning indication of the specified optical distribution disc position.

[0038] The application can accurately collect the state of the corresponding port and the correspondence between the port and the optical fiber through the low-cost, multi-channel optical fiber port management device; and the optical fiber port management device is small in size and convenient to integrate at the fusion fiber disc. The independent channels will not introduce channel cross interference due to the centralized switching of radio frequency signals.

[0039] Referring to Figure 5 As shown, the application also provides an optical fiber port management system, which includes the optical fiber port management device and the handheld terminal 5, and the handheld terminal 5 is signal connected to the micro control circuit of the optical fiber port management device.

[0040] Further, in an embodiment, the handheld terminal 5 is connected to the micro control circuit of the fiber port management device through a wired bus or connected to the micro control circuit through a wireless connection. Referring to Figure 5 As shown, each electronic tag collection disc 2 can be connected to the handheld terminal 5 through a wired bus or wirelessly, the handheld terminal 5 can periodically poll the information of each electronic tag collection disc 2, and the information of the electronic tag collection disc 2 includes but is not limited to the machine room, the machine cabinet, the machine frame, the physical address, the connection state information of the optical distribution disc corresponding to the fiber port, and the unique identification information of the fiber connector of the corresponding port.

[0041] In the above embodiment, the electronic tag 1 located at the fiber connector can use an NFC near field communication electronic tag 1, and the corresponding attribute information can be directly written to the fiber connector electronic tag 1 through a mobile phone, and the attribute information includes but is not limited to the service attribute of the fiber, the fiber routing information, etc.

[0042] The fiber port management device of the present application can efficiently and in batches collect the information of multiple port states and corresponding fiber connectors through the electronic tag collection disc 2 installed at each fusion disc; the address of the electronic tag collection disc 2 is associated and bound with the physical position address, and the indication light 4 of the electronic tag collection disc 2 can quickly realize the positioning of the port position; at the same time, the independent analog switch can realize multi-channel electronic tag 1 data collection, which avoids the problems of large circuit volume and space, wiring difficulty, reading crosstalk, and poor impedance matching consistency in the related art.
