Description

Technical Field

[0001] This invention belongs to the field of communication wiring technology, and relates to an optical fiber wiring system, especially an optical fiber wiring system with information acquisition function. Background Technology

[0002] Existing optical distribution units (ODFs) are all passive devices and mostly modular in design. Because they lack the ability to collect operational information, their operational status cannot be monitored in real time during remote communication system operation monitoring, resulting in monitoring blind spots. In communication resource management, the frequent discrepancies between diagrams and reality cause many inconveniences for operational mode planning and emergency fault handling.

[0003] A search revealed no publicly available literature of the same or similar prior art as this invention. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and propose an optical fiber distribution system with information acquisition function, which can collect and monitor optical fiber distribution data in real time.

[0005] The present invention solves its practical problem by adopting the following technical solution:

[0006] A fiber optic distribution system with information acquisition function includes: a modular fiber optic distribution unit, a switch data acquisition unit, and a multi-channel signal acquisition device; the switch data acquisition unit is installed in the modular fiber optic distribution unit, and multiple data lines are led out from the switch data acquisition unit and connected to the signal acquisition devices of each junction box in the modular fiber optic distribution unit to realize the acquisition of flange operating status information in the fiber optic distribution unit.

[0007] Moreover, the multi-channel signal acquisition device consists of multiple sets of signal acquisition units and spring trigger plates. The signal acquisition units and spring trigger plates in each set are combined together to acquire the operating status of a single flange in the junction box.

[0008] Moreover, multiple signal collectors are uniformly fixed inside the junction box by the fixing clamps above them. Each signal collector is located inside the flange on the junction box, and its contact is facing (or inserted) into one of the mounting holes on the flange. The spring trigger plate is installed on the outside of the flange and fixed to one mounting hole on the flange with bolts. The other end serves as a moving head and extends into another mounting hole on the flange to achieve cooperation with the signal collector.

[0009] Furthermore, the operating status of each flange is acquired using an independent single-channel flange switching signal acquisition circuit. This single-channel flange switching signal acquisition circuit includes: two parallel resistors R1 connected in series with a current-limiting resistor R2 to form an input circuit; an optocoupler is connected across the current-limiting resistor R2 to control the conduction of the optocoupler by the current flowing through the circuit; a pull-up resistor R3 is connected in series at the output of the optocoupler to ensure that the phototransistor enters the saturation region as soon as possible; and a Schottky diode is connected in parallel across the current-limiting resistor R2 to prevent large input voltage surges.

[0010] Furthermore, the switch data acquisition unit includes an acquisition unit, a buffer unit, a communication interface unit, and multiple data cable connector areas; the output end of the acquisition unit is connected to the buffer unit and is used to store the operating status information of each fiber optic distribution unit flange collected by the acquisition unit; the output end of the buffer unit is connected to the communication monitoring system through the communication interface unit and is used to send the operating status information of each fiber optic distribution unit flange to the communication monitoring system when the switch data acquisition unit communicates with the communication monitoring system.

[0011] Furthermore, the data cable is a 13-core chromatographic data cable with a shielding layer, and both ends are equipped with ribbon cable plugs. One end is connected to the socket area on the switch data acquisition unit system, and the other end is connected to the data cable socket of the fiber optic distribution unit. Each data cable contains a common signal line, which is connected to the common ground in the junction box to ensure that the loop connection of the other single-core lines through each flange is achieved.

[0012] Advantages and beneficial effects of the present invention:

[0013] 1. This invention modifies the structure of the original modular ODF by adding a switch data acquisition unit system and a multi-channel signal acquisition device to monitor the operating conditions of each fiber optic flange. The collected information is then uploaded to the communication monitoring system via the communication port on the switch data acquisition unit system, thereby achieving real-time acquisition of operating data.

[0014] 2. This invention can be applied to all ODF modules to collect ODF operational information, filling a gap in the digital operation and maintenance of communication systems. This invention eliminates blind spots in real-time monitoring of ODF operational status, enabling online management of ODF resources. Utilizing constantly updated information, it assists master station monitoring personnel in making decisions regarding changes occurring at remote stations. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings:

[0023] A fiber optic distribution system with information acquisition capabilities, such as Figures 1 to 5 As shown, it includes: a modular fiber optic distribution unit, a switch data acquisition unit, and a multi-channel signal acquisition device; the switch data acquisition unit is installed on the modular fiber optic distribution unit, and multiple data lines are led out from the switch data acquisition unit to connect to the signal acquisition devices of each junction box in the modular fiber optic distribution unit, so as to realize the acquisition of flange operating status information in the fiber optic distribution unit.

[0024] In this embodiment, a multi-channel signal acquisition device is designed. The multi-channel signal acquisition device consists of multiple sets of signal acquisition units and spring trigger plates. Each signal acquisition unit and spring trigger plate is combined together to acquire the operating status of a single flange in the junction box.

[0025] In this embodiment, multiple signal collectors are uniformly fixed inside the junction box using mounting clips on top of them. Each signal collector is located inside the flange on the junction box, with its contact facing (or inserted into) one of the mounting holes on the flange. The spring trigger plate is installed on the outside of the flange and fixed to one mounting hole on the flange with bolts. The other end serves as a moving head, extending into another mounting hole on the flange to cooperate with the signal collector. Each signal collector is connected to a data cable socket inside the junction box via a single-core wire.

[0026] When the flange is not in use, the moving head does not contact the collector contact. When the flange is inserted into the fiber optic patch cord, the moving head triggers the collector via a spring plate and sends a signal.

[0027] The fixing clamps are installed in suitable positions inside the junction box (such as the sides or middle of the fixing clamps) and secured with bolts or optimized molds.

[0028] In this embodiment, the operating status of each flange is acquired using an independent single-channel flange switch signal acquisition circuit, as shown in the schematic diagram of the single-channel flange switch signal acquisition circuit. Figure 4 As shown, it can be set that when the OUT1 output is high, the flange is in an unused state; when the output is low, the flange is in a used state.

[0029] The single-channel flange switch quantity acquisition circuit includes: two parallel resistors R1 and a current-limiting resistor R2 connected in series to form an input circuit; the two ends of the current-limiting resistor R2 are connected to an optocoupler so that the current flowing through the circuit can control the conduction of the optocoupler; a pull-up resistor R3 is connected in series at the output end of the optocoupler to ensure that the phototransistor enters the saturation region as soon as possible; and a Schottky diode is connected in parallel across the current-limiting resistor R2 to prevent large input voltage sudden changes.

[0030] An optocoupler is used to perform an electro-optical-electro-electrical conversion of the signal, thereby isolating the input and output and avoiding interference caused by electrical characteristics and harsh working environments.

[0031] In operation, the circuit consists of two resistors R1 and a current-limiting resistor R2 forming the input loop. The resistance values ​​are adjusted to control the current flowing through the loop and thus the conduction of the optocoupler. Resistor R3 is a pull-up resistor; an appropriate value is selected to ensure the phototransistor enters the saturation region as quickly as possible. Simultaneously, to protect the optocoupler and prevent large input voltage surges, a Schottky diode is connected in parallel across the current-limiting resistor R2.

[0032] In application, when the flange is not plugged in with a jumper, the terminal is in an inactive state, the contacts of the signal collector are not triggered, the acquisition circuit is in an open circuit state, the optocoupler is not conducting, and the output terminal OUT1 is at a high level. When the flange is plugged in with a jumper, the terminal is engaged, the contacts of the signal collector are triggered, the acquisition circuit is conducted, thus the optocoupler conducts, the output terminal OUT1 is at a low level, and a signal is emitted.

[0033] In this embodiment, the switch data acquisition unit is as follows: Figure 1 As shown, it includes a data acquisition unit, a buffer unit, a communication interface unit, and multiple data cable connector areas; the output end of the data acquisition unit is connected to the buffer unit and is used to store the operating status information of each fiber optic distribution unit flange collected by the data acquisition unit; the output end of the buffer unit is connected to the communication monitoring system through the communication interface unit and is used to send the operating status information of each fiber optic distribution unit flange to the communication monitoring system when the data acquisition unit communicates with the communication monitoring system.

[0034] It is equipped with a communication address DIP switch for the acquisition unit, has an n*12 channel acquisition capacity, and adopts serial data acquisition and parallel output mode.

[0035] The communication interface unit is equipped with an RS485 interface, an RS232 communication interface, or an IP Ethernet interface.

[0036] The communication interface unit includes an RS485 interface, an RS232 communication interface, or an IP Ethernet interface. It is used to meet the different communication interface requirements of the communication monitoring system.

[0037] In this embodiment, the data cable is a 13-core colorimetric data cable with a shielding layer, and both ends are equipped with ribbon cable plugs. One end is connected to the socket area on the switch data acquisition unit system, and the other end is connected to the data cable socket of the fiber optic distribution unit. The data cable socket ensures that the junction box and the switch data acquisition unit system are independent of each other. This separate design facilitates the installation and maintenance of the junction box.

[0038] Each data line contains a common signal line connected to the common ground in the junction box, ensuring that the loop connection of the remaining single-core lines through the information acquisition circuits of each flange is achieved.

[0039] In practical applications, the switch data acquisition unit system collects the operating status information of the flanges in each fiber optic distribution unit in real time through the single-channel flange acquisition circuit and stores it in the buffer unit. When a flange inserts (or removes) a jumper fiber to change its usage status, it triggers the single-channel flange acquisition circuit OUT1 to output a low level (or high level), and the acquisition unit collects this change information in real time and stores it in the buffer unit.

[0040] The communication monitoring system can communicate with the switch data acquisition unit system in real time through a certain type of port (RS485 interface, RS232 communication interface or IP Ethernet interface), receive the stored data of the switch data acquisition unit system's buffer unit, and realize the real-time display of flange operating status information in each fiber optic distribution unit at the main station.

[0041] This invention comprehensively considers the characteristics of existing modular ODFs and the influence of external factors, and proposes an optical fiber distribution system with information acquisition function. Its implementation process is as follows:

[0042] 1. Packaging and testing of the switch data acquisition unit circuit board. The acquisition unit adopts opto-isolation mode, the buffer unit completes the serial-to-parallel conversion of data, and the communication interface unit completes the data communication between the upper-level master station and the unit module. External interfaces include the data cable pin area socket for data acquisition, D9 interface, and IP network port, etc. Please see the system structure diagram and single-channel flange acquisition circuit diagram in the figure.

[0043] 2. Modification of the fiber optic tray and design and installation of the signal acquisition unit: A fixing clamp for securing the signal trigger is added inside the fiber optic tray. A special spring plate is installed on the flange, and the signal is triggered after inserting the fiber optic jumper. Please refer to the flange modification structure diagram in the attached figure.

[0044] 3. System integration, completing the signal acquisition and uploading function test.

[0045] The innovation of this invention lies in:

[0046] 1. This invention adds a switch data acquisition unit to a modular fiber optic distribution unit. Multiple data lines are led out from the acquisition unit and connected to each junction box within the fiber optic distribution unit. Each data line contains a common signal line, and the remaining single-core wires are connected to each fiber optic flange. A signal acquisition device is installed at each flange to collect the usage status of each fiber optic flange.

[0047] 2. Develop a dedicated switch data acquisition unit, including functional areas such as acquisition unit, buffer unit, communication interface unit, and data cable connector area. It is equipped with a communication address DIP switch for the acquisition unit, has an n*12 channel switch acquisition capacity, adopts serial data acquisition and parallel output mode, and the communication interface unit is equipped with RS485 interface, RS232 communication interface or IP Ethernet interface.

[0048] 3. Dedicated data cable: A 13-core shielded color-coded data cable is used, with a ribbon cable connector at one end and the other end connected to the junction box of the fiber optic distribution unit, fixed to the signal acquisition unit at each fiber optic flange. This separate design of the data cable and switch data acquisition unit facilitates fiber optic splicing and tray mounting.

[0049] 4. Design a multi-channel signal acquisition device, consisting of multiple sets of acquisition units and spring trigger plates. Each set of acquisition units and spring trigger plates is used to acquire the in-use status of a single fiber optic flange within a junction box. Each acquisition unit is fixed inside the junction box on the flange by a clamp and connected to a data cable to form a closed loop for data acquisition. Each spring trigger plate is mounted on the flange; when a fiber optic patch cord is inserted into the flange, the spring trigger plate triggers the acquisition unit to send a signal.

[0050] It should be emphasized that the embodiments described in this invention are illustrative rather than limiting. Therefore, this invention includes, but is not limited to, the embodiments described in the specific implementation. Any other implementations derived by those skilled in the art based on the technical solutions of this invention are also within the scope of protection of this invention.
