Description

Technical Field

[0001] The present application relates to the field of optical cross-box technology, for example, to an intelligent optical cross-box access control system based on laser energy fiber optic transmission technology. Background Art

[0002] With the development of optical communication networks, optical cross-connect boxes (CNCs), essential equipment for terminating and patching optical cables at the backbone and distribution layers of optical cable transmission, are deployed in large numbers and play a crucial role in the transmission links of optical communication networks. Managing CNCs, enhancing their routine maintenance, and ensuring their safe operation are core tasks in optical communication network operations and maintenance.

[0003] Because optical cross-connect boxes are mostly installed outdoors in uncontrolled locations and are passive enclosures, conventional cross-connect boxes lack monitoring equipment to monitor and control them. If the door is unlocked or the lock is damaged, it can remain open and unattended for extended periods. This can lead to casual fiber optic disconnection by passersby, nibbling and tearing by small animals, and fiber optic transmission failures due to human and climatic factors such as humidity and freezing in rainy and snowy weather, and dust contamination in windy and sandy weather. When the door, box, or internal cables are damaged, management and maintenance personnel cannot promptly monitor the cross-connect box's status and location, compromising the reliability, security, and confidentiality of the optical communication network.

[0004] Currently, the main solution to this problem on the market is to use an intelligent electronic door lock system. The system includes a battery, an electric door lock, a management controller with a wireless communication module, and a monitoring and management platform. It can realize remote authorization management of unlocking and real-time reporting of door status. Its monitoring and management platform mainly receives and processes information related to the optical cross-connect box through the wireless communication module. However, the wireless communication module has the disadvantages of unstable signal and easy shielding or interference. In addition, the battery also needs to be replaced frequently, which has the disadvantage of high maintenance cost.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present disclosure provides an intelligent optical cross-connect access control system based on laser energy fiber 1-3 transmission technology. Figures 1 to 3 , including a communication-connected intelligent optical cross-box access control network management system 1-1 and a computer room gateway 1-2, each computer room gateway 1-2 is connected to multiple optical cross-boxes, and the computer room gateway 1-2 is provided with an integrated module for generating energy laser and communication laser and coupling them, and the optical cross-box is provided with an optical cross-box controller 1-4 for separating the energy laser and the communication laser, and the integrated module is connected to the optical cross-box controller 1-4 through the optical fiber 1-3, so that the computer room gateway 1-2 is connected to the optical cross-box through the optical fiber 1-3 for communication and powering the equipment in the optical cross-box.

[0021] An integrated module generates energy lasers and communication lasers, which are coupled and then transmitted to the optical cross-box controller 1-4. The optical cross-box controller 1-4 separates the energy lasers and communication lasers into communication lasers and energy lasers, uses the communication lasers for communication, and uses the energy lasers to power the smart electronic locks 1-9 and multiple sensors within the optical cross-box. In this way, energy and data communication are combined and transmitted via optical fiber 1-3, solving the power supply and information transmission problems of the passive optical cross-box simultaneously through a single optical fiber 1-3. This enables real-time monitoring of environmental variables within the optical cross-box and timely response to remote control of the electronic locks. This significantly addresses the problems of low security and reliability of information transmission and high operation and maintenance costs in existing optical cross-box monitoring.

[0022] In one embodiment, referring to Figure 2 The integrated module includes a first control module 2-1, an electro-optical conversion module 2-2, a first optical communication module 2-3 and a first coupling module 2-4. The first control module 2-1 is communicated with the intelligent optical cross-box access control network management system 1-1. The electro-optical conversion module 2-2 and the first optical communication module 2-3 are respectively connected to the first control module 2-1 and the first coupling module 2-4. The first coupling module 2-4 is connected to the optical cross-box through the optical fiber 1-3.

[0023] The integrated module inside the computer room gateway 1-2 integrates the first control module 2-1, the electro-optical conversion module 2-2, the first optical communication module 2-3, and the first coupling module 2-4. The first control module 2-1 performs various logical controls on the entire computer room gateway 1-2, including turning the electro-optical conversion module 2-2 on and off, controlling the amount of transmitted electrical energy, and forwarding data between the network management system and the optical cross-connect controller 1-4. The electro-optical conversion module 2-2 primarily converts electrical energy into laser light of a specific wavelength that can be transmitted in the optical fiber 1-3 and that can carry a certain amount of energy. The first optical communication module 2-3 primarily converts data information between optical and electrical sources. The first coupling module 2-4 primarily couples the laser light generated by the electro-optical conversion module 2-2 with the laser light of the optical communication module 2-3.

[0024] In one embodiment, referring to Figure 3 The optical cross-box controller 1-4 includes a second coupling module 3-4, a light energy conversion electric energy module 3-2, a second optical communication module 3-3, and a second control module 3-1. The second coupling module 3-4 is connected to the computer room gateway 1-2 through the optical fiber 1-3, and the light energy conversion electric energy module 3-2 and the second optical communication module 3-3 are respectively connected to the second coupling module 3-4 and the second control module 3-1.

[0025] In one embodiment, referring to Figure 1 and Figure 3The optical cross-box is equipped with an access control sensor 1-5, a water immersion sensor 1-7, a vibration sensor 1-6 and a temperature and humidity sensor 1-8, and the optical cross-box controller 1-4 is also equipped with a sensor detection module 3-5; the sensor detection module 3-5 is connected to the second control module 3-1, and the access control sensor 1-5, the water immersion sensor 1-7, the vibration sensor 1-6 and the temperature and humidity sensor 1-8 are connected to the sensor detection module 3-5.

[0026] In one embodiment, referring to Figure 1 and Figure 3 , an intelligent electronic lock 1-9 is also provided in the optical cross-box, and the optical cross-box controller 1-4 is also provided with an electronic lock control module 3-6, which is connected to the intelligent electronic lock 1-9 and the electronic lock control module 3-6 is connected to the second control module 3-1.

[0027] The optical cross-connect box controller 1-4 integrates a second control module 3-1, a light-to-electrical energy module 3-2, a second optical communication module 3-3, a second coupling module 3-4, a sensor detection module 3-5, and an electronic lock control module 3-6. The second coupling module 3-4 primarily separates the laser light transmitted by optical fiber 1-3 into energy laser light and communication laser light. The light-to-electrical energy module 3-2 primarily converts the energy-carrying laser light of a specific wavelength transmitted through optical fiber 1-3 into electrical energy, thereby powering the access control system within the optical cross-connect box. The second optical communication module 3-3 primarily converts data between optical and electrical sources. The second control module 3-1, through the sensor detection module 3-5 and the electronic lock control module, collects real-time information from the access control sensor 1-5, vibration sensor 1-6, water sensor 1-7, temperature and humidity sensor 1-8, and smart electronic door lock 1-9, and transmits this information to the network management system via the computer room gateway 1-2.

[0028] In this embodiment, the sensor detection modules 3-5 are specifically access control, water immersion, vibration, and temperature and humidity detection modules. The intelligent optical cross-connection box access control network management system 1-1 can use sensors to collect, present, and manage the status information of the optical cross-connection box in real time, support remote control of the intelligent electronic lock 1-9 of the optical cross-connection box, and support the management of multiple optical cross-connection boxes.

[0029] During a complete operational process, the computer room gateway 1-2 generates energy lasers for power transmission and communication lasers for communication as needed. These lasers are coupled via a coupler. After coupling, the energy lasers and communication lasers are transmitted via optical fiber 1-3 to the optical cross-box controller 1-4. The optical cross-box controller 1-4 separates the energy lasers from the communication lasers via a coupler. The energy lasers are then connected to the optical energy conversion module 3-2, which converts the collected energy into power for the optical cross-box controller 1-4. The optical cross-box controller 1-4 collects real-time information from the smart electronic lock 1-9, access control sensor 1-5, temperature and humidity sensor 1-8, vibration sensor 1-6, and water level sensor 1-7, converting it into communication optical signals. These signals are then transmitted to the smart optical cross-box access control network management system 1-1 via the computer room gateway 1-2. The optical cross-box controller 1-4 can also control the opening and closing of the smart electronic door lock 1-9 based on commands transmitted from the smart optical cross-box access control network management system 1-1 via the computer room gateway 1-2. The computer room gateway 1-2 receives the information reported by the optical cross-connect box controller 1-4 and uploads it to the network management system simultaneously. The intelligent optical cross-connect box access control network management system 1-1 monitors, manages, and presents the optical cross-connect box intelligent electronic lock 1-9, temperature and humidity and other information in real time based on the information uploaded by the controller, and remotely opens the door of the optical cross-connect box intelligent electronic lock 1-9 as needed.
