Description

Technical Field

[0001] This invention relates to the field of optical fiber communication equipment technology, and in particular to an intelligent tray for monitoring the usage status of optical fiber ports using infrared sensors. Background Technology

[0002] With the development of fiber optic communication, fiber optic resources are used in all corners of society. However, since the fiber optic cable splicing carrier in the equipment room still adopts the tray splicing method, on-site personnel still need to perform the service activation fiber jumper operation at the tray port. Therefore, traditional trays cannot avoid situations such as non-compliance with the order, illegal fiber insertion, and random fiber insertion.

[0003] In actual use of tray-based fiber optic jumper operation, the lack of supervision during on-site construction leads to errors in port data recording, resulting in discrepancies between the on-site ports and the recorded occupancy status. This necessitates regular manual checks and reorganization of available ports, resulting in losses of time, manpower, and resources. Summary of the Invention

[0004] This invention provides an intelligent tray that uses an infrared sensor to monitor the usage status of fiber optic ports. Its advantage is that it uses an infrared sensor to monitor the occupancy status of the tray ports, thus avoiding the constraints of traditional intelligent monitoring equipment that still requires intelligent jumpers or intelligent jumper management after adopting an intelligent tray. Target monitoring can be achieved using only traditional jumpers, thereby reducing the cost of intelligent tray management and monitoring equipment.

[0005] The above-mentioned objective of the present invention is achieved through the following technical solution: an intelligent tray for monitoring the usage status of fiber optic ports using infrared sensors, characterized in that the tray includes a tray shell and a PCB control board disposed within the tray shell. The tray shell is provided with multiple fiber optic adapters, and the PCB control board is provided with infrared sensors corresponding to each fiber optic adapter. The detection direction of the infrared sensors faces the outer interface of the corresponding fiber optic adapter. When the infrared sensors are working, they emit infrared light to the outer interface of the fiber optic adapter. The PCB control board is communicatively connected to a separate upstream device.

[0006] The present invention is further configured such that the tray housing is provided with a port status indicator hole, and the PCB control board is provided with a port LED indicator corresponding to the position of the port status indicator hole.

[0009] The present invention is further configured such that the PCB control board is installed inside the upper cover, and the port status indicator light hole is disposed on the upper cover.

[0010] The present invention is further configured such that the upper cover has an outer edge on one side of the fiber optic adapter.

[0011] The present invention is further configured such that a support member for supporting and positioning the PCB control board is provided on the inner side of the upper cover, and the PCB control board is mounted on the upper cover by screws.

[0012] The present invention is further configured such that a main control ARM chip is provided on the PCB control board, and the infrared sensor is connected to the main control ARM chip through a circuit.

[0013] The present invention is further configured such that the PCB control board is provided with a communication network port, and the tray shell is provided with a network port mounting slot for the communication network port to extend out.

[0014] The present invention is further configured such that the infrared sensor is provided with an orientation differentiation mark.

[0015] The present invention is further configured such that the detection position of the infrared sensor is the outer sleeve of the optical fiber connector connected to the optical fiber adapter.

[0016] In summary, the beneficial effects of the present invention are as follows: 1. In this invention, the tray cover is easily disassembled and installed manually through the fasteners and slots connecting the bottom shell and the top cover; 2. In this invention, the PCB control board is equipped with an infrared sensor, which can detect whether the fiber optic connector has an inserted port, thereby determining the port occupancy status, without the need to use a specific smart fiber or to make intelligent modifications to the fiber optic connector; 3. In this invention, the port occupancy status is monitored by an infrared sensor, which eliminates the need for intelligent jumpers or intelligent jumpers. Target monitoring can be achieved using only traditional jumpers, thereby reducing the cost of intelligent pallet management and monitoring equipment. 4. The tray in this invention has a network port on one side, which facilitates power supply and data transmission to the smart tray via a network cable.

[0017] 5. In this invention, the infrared sensor determines whether the receiving port is affected by external light input when the power is on and off, thus preventing errors in port identification data. After detecting and identifying the influence of external light input, the network management platform proactively alerts the port to an external light input influence alarm, reducing the port information error rate.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example: Reference Figures 1-5 An intelligent tray for monitoring the usage status of fiber optic ports using an infrared sensor, the tray includes a tray housing 1 and a PCB control board 2 disposed inside the tray housing 1. The tray housing 1 is provided with multiple fiber optic adapters 3. In an embodiment of the present invention, as shown in the figure, taking a common tray with 12 fiber optic adapters 3 as an example, the fiber optic adapters 3 are SC / FC adapters, and the fiber optic adapters 3 are equipped with dust caps 4.

[0022] The tray housing 1 is provided with a fiber fusion tray 5. The tray housing 1 includes a bottom shell 6 and a top cover 7 that are interlocked. The fiber fusion tray 5 is disposed on the bottom shell 6, and the bottom shell 6 is provided with a plurality of first grooves 8 for installing the fiber optic adapter 3.

[0023] The PCB control board 2 is equipped with infrared sensors 9, each corresponding to one of the fiber optic adapters 3, i.e., there are 12 infrared sensors 9, as shown in the figure. The infrared sensors 9 are located inside the tray housing 1. The detection direction of each infrared sensor 9 faces the outer interface of the corresponding fiber optic adapter 3. When the infrared sensor 9 is working, it emits infrared light towards the outer interface of the fiber optic adapter 3. The detection position of the infrared sensor 9 is the outer sleeve of the fiber optic connector connected to the fiber optic adapter 3. When the fiber optic connector is inserted into the fiber optic adapter 3, the corresponding infrared sensor 9 can detect the fiber optic connector.

[0024] The tray housing is provided with port status indicator light holes, and the PCB control board is provided with port LED indicators corresponding to the positions of the port status indicator light holes. These port LED indicators are used to indicate the port status and are controlled by the PCB control board 2 to flash. Each port of the tray has a port LED indicator. When a port alarm occurs, the port LED indicator emits red light and flashes through the port status indicator light hole 10 to indicate the location of the corresponding port alarm.

[0025] The PCB control board 2 is installed inside the upper cover 7, and the port status indicator light 10 is set on the upper cover 7. The upper cover 7 has an outer edge 11 on one side of the fiber optic adapter 3. The outer edge 11 protects the PCB control board 2 and shields the infrared sensor 9 from light, reducing the possible influence of external light sources on the infrared sensor 9 and reducing the possibility of port identification errors.

[0026] The PCB control board 2 is communicatively connected to a separate upstream device. The PCB control board 2 is equipped with a communication network port 12, and the tray housing 1 is equipped with a network port mounting slot 13 for the communication network port 12 to extend out. The communication network port 12 is used to connect to the upstream device and power supply.

[0027] The inner side of the upper cover 7 is provided with a support member 14 for supporting and positioning the PCB control board 2. The PCB control board 2 is mounted on the upper cover 7 with screws. The PCB control board 2 is provided with a main control ARM chip. The infrared sensor 9 is connected to the main control ARM chip through a circuit, and the communication network port 12 is also connected to the main control ARM chip.

[0028] The infrared sensor 9 has a light-emitting port 15 and a light-receiving port 16, and an orientation identification mark 17. The infrared sensor 9 determines the usage status of the fiber optic port through light-emitting and light-receiving logic.

[0029] PCB control board 2 controls the power on and off of the light-emitting pin of infrared sensor 9. If the light-receiving port 16 does not detect light input when the infrared sensor 9 is powered off, but detects light input when the light-receiving port 16 is powered on, it can be proven that a jumper is inserted into the port corresponding to the infrared sensor 9 on site, and the port is identified as occupied.

[0030] PCB control board 2 controls the power on and off of the light-emitting pin of infrared sensor 9. If the light receiving port 16 can detect external light input in both the power-on and power-off states of infrared sensor 9, it can be proven that there is external ambient light input on site, causing the sensor to misjudge. The network management platform will receive an alarm and indicate strong light interference on site, and personnel need to be sent to the site to check and handle the relevant situation.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
