Technical Field

The application relates to the technical field of aviation, in particular to a parallel single-lamp control system based on optical fiber communication and applied to airport navigation aid.

Background

An advanced scene activity guidance and control system (A-SMGCS) is a system for improving the operation efficiency of an airport, ensuring the operation safety and meeting the requirements of the airport, and is defined by the International civil aviation organization as follows: a system for providing surveillance, routing and guidance for control of aircraft and vehicles in order to maintain published rates of movement while maintaining required safety under all weather conditions that meet airport visibility operating levels.

At present, in airport navigation light systems with A-SMGCS below level 2 or even without A-SMGCS introduced, a single-light monitoring system based on PLC carrier communication is generally adopted. However, the single-lamp monitoring system based on PLC carrier communication has many disadvantages, and especially when the whole single-lamp control system is applied to a 3-level or 4-level a-SMGCS monitoring system in a large airport, the a-SMGCS system may not monitor the whole light guiding system, and even may not bear the overall cooperative operation of a high load.

Therefore, there is a need in the art for a system that can monitor the entire light guidance system reliably for a long period of time in practical applications.

It is noted that in the following description, reference is made to the accompanying drawings which illustrate several embodiments of the present application. It is to be understood that other embodiments may be utilized and that mechanical, structural, electrical, and operational changes may be made without departing from the spirit and scope of the present application. The following detailed description is not to be taken in a limiting sense, and the scope of embodiments of the present application is defined only by the claims of the issued patent. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It will be further understood that the terms "comprises," "comprising," and/or "comprising," when used in this specification, specify the presence of stated features, operations, elements, components, items, species, and/or groups, but do not preclude the presence, or addition of one or more other features, operations, elements, components, items, species, and/or groups thereof. The terms "or" and/or "as used herein are to be construed as inclusive or meaning any one or any combination. Thus, "A, B or C" or "A, B and/or C" means "any of the following: a; b; c; a and B; a and C; b and C; A. b and C ". An exception to this definition will occur only when a combination of elements, functions or operations are inherently mutually exclusive in some way.

In order to realize the basic functions of safety, high efficiency, smoothness and no error in the operation of the whole airport scene, the following basic requirements must be met for the whole airport navigation light/single light monitoring under the A-SMGCS 4 level condition, including the whole light communication control system: 1) at least 45 central line light (TCL) groups can be sent with switch/feedback commands every second, and at most 400 stop lights around the take-off and landing runway are issued with switch commands; 2) the lighting change caused by the change of the running direction and the like can be processed at any time, namely 500 switch/feedback instructions per second need to be processed; 3) for each cluster of center line lights (TCLs), the system must have a processing power of at least 10 switches per second. For the take-off and landing runway to stop lights, the system must have a processing capability of switching on and off at least 30 times per second; 4) for taxiway stop lights, the system must have at least 65 switches per second, and the entire A-SMGCS/ALCMS coordinated command and monitoring system must have the capability to send at least 120 switch/feedback commands per second, in addition to other required commands.

However, the PLC cable carrier communication scheme has relatively strict requirements in terms of system response time, hardware requirements, installation, maintenance, and the like, so that the PLC cable carrier communication scheme is not satisfactory for application in an aid-to-navigation light guidance system with more than three levels of a-SMGCS, and specific disadvantages are described as follows.

1) The deficiency of the PLC power carrier communication scheme in terms of system response time is that once the response time exceeds 80 lamps, the response time is much longer than 1 second, and the system does not meet the requirements of a-SMGCS level 3 or level 4, and when a plurality of single lamps fail, the reliability of the system is significantly reduced or even out of control.

2) The deficiency of the PLC power carrier communication scheme in terms of hardware requirements is that the requirements for lamps and related hardware are high and the carrier loop is easily interfered (for example, interference waves generated between cables of the primary loop easily affect the light monitoring communication signals, extra shielding is required, the number of cables in the pipeline is also limited, otherwise, interference which is difficult to eliminate is easily formed); the quality requirement on the lamp transformer is high; the requirements on the dimmer are high; the insulation requirements for the whole loop are high (for example, when a new system is put into an operating state, the insulation requirements are higher than 50 megaohms, and the requirements for the water resistance and the low impedance of a plug and a socket of a cable in the loop and even the bending radius in the installation of the cable are high); the skill level of the installation worker is highly required.

3) The defects of the PLC power carrier communication scheme in the aspect of installation are represented by high requirements on the installation scheme and materials and high requirements on the technical level of installation operators.

4) The defects of the PLC power carrier communication scheme in maintenance are that personnel who participate in maintenance and repair daily, including field-resident after-sales service personnel, have high professional skill requirements, and the later maintenance cost is high.

Therefore, even the most excellent PLC cable carrier communication scheme at present cannot reliably execute the tasks for a long time in practical application, so that the PLC cable carrier communication scheme cannot be applied to the navigation light guide system with more than three levels of A-SMGCS.

In view of the above, the invention provides a parallel single-lamp control system based on optical fiber communication for airport navigation aid, which adopts optical fiber communication to replace the traditional power line carrier communication scheme, and can be well applied to navigation aid light guide systems with more than three levels of A-SMGCS. The invention has excellent performance on the system reaction time (even if the number of single loop single lamps is more than 200, the system reaction time is less than 1 second, and the invention meets the requirements of A-SMGCS grade 3 or grade 4); no special requirements are made on the aspects of the dimmer or the insulation of the whole loop and the like in terms of hardware; the installation aspect has low requirements on experience of installation personnel; the maintenance is simple and convenient. In addition, the sunken type concentration box body adopted by the invention is arranged in the underground space outside the taxiway, so that the influence on the ground taxiway is greatly reduced; because the control devices are connected in parallel, any plurality of control devices can be arranged within the construction allowable range; the invention does not need to change the existing situation of the taxi track centerline light, and is particularly suitable for the upgrading and updating transformation of the navigation aid light of the airport which is normally operated.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention are further described in detail by the following embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 is a schematic structural diagram illustrating a parallel single-lamp control system based on optical fiber communication for airport navigation aid according to an embodiment of the present invention. The parallel single-light control system of the present embodiment includes a plurality of navigation lights 11, a plurality of single-light control units 12, one or more communication modules 13, and a housing case (not shown). The single lamp control unit 12 is powered by a field power supply circuit 14 and performs lamp control management on the navigation aid lamp 11 connected with the single lamp control unit; the accommodating box body is used for accommodating all the single lamp control units; the communication module 13 is responsible for communication transmission of all the single lamp control units 12 in the accommodating box body; all the communication modules 13 are connected in series to form an optical fiber ring network, each communication module 13 is connected in parallel with the single lamp control unit 12 which is in charge of communication transmission, and optical fibers are used as transmission media to carry out parallel single lamp control; the light control instruction of the navigation aid light is transmitted to each communication module by the airport navigation aid light monitoring system or the A-SMGCS system through the optical fiber ring network, and then transmitted to each single light control unit connected with the communication module in parallel.

Specifically, the communication module 13 is connected with the airport navigation light monitoring system 16 or the a-SMGCS system through the ring bus 15 (i.e. directly connected with the a-SMGCS integrated platform SMAN). The light control instruction of the navigation aid light is sent to each communication module by the airport navigation aid light monitoring system or the A-SMGCS system through the optical cable bus, and then sent to each single light control unit connected in parallel by each communication module.

Optionally, each communication module 13 and each single lamp control unit 12 in the corresponding group may be implemented based on RJ45 interfaces, RJ45 interfaces equal to the number of the single lamp control units in the group are provided in the communication module 13, and each RJ45 interface is correspondingly connected to a communication interface module in the single lamp control unit, thereby implementing communication connection. However, it should be understood that the communication interface related to this embodiment is not limited to the RJ45 interface, and RS232, RS485, RS422, etc. may also be used, and this embodiment is not limited.

In the embodiment, the communication mode of the lamp control system is changed from the traditional PLC power carrier communication scheme to the communication through the optical fiber, and the communication through the optical fiber has excellent system response time and has no harsh requirements on hardware, installation, maintenance and the like of an airport, so that the lamp control system can be well applied to the navigation light guide system with more than three levels of A-SMGCS.

In an implementation manner that may be selected in this embodiment, the single lamp control unit specifically includes a control module, a communication interface module, and a power supply module. The communication interface module is connected with the corresponding communication module and used for receiving the lamp control instruction through the communication module; the control module is connected with the corresponding navigation aid lamp and performs lamp control management on the navigation aid lamp according to the lamp control instruction; the power module is connected with the power supply circuit 13, the power supply circuit 13 is connected with a plurality of transformers 17, and each transformer 17 is correspondingly connected with the single lamp control unit 12 or the communication module 13 so as to supply power to the connected single lamp control unit 12 or the communication module 13.

To facilitate understanding of those skilled in the art, the single lamp control unit in the present embodiment will be further explained and illustrated with reference to fig. 2. In fig. 2, the single-lamp control unit 20 includes a cable interface 21, an optical fiber interface 22, an output interface 23, a photoelectric conversion module 24, an a/D conversion module 25, and a central processing unit 26, and the photoelectric conversion module and the a/D conversion module are connected to each other and are connected to the central processing unit. The cable interface 21 is from an isolation transformer and is used for supplying power to the single lamp control unit; the photoelectric conversion module is connected with the optical signal through the optical fiber interface 22 and then converts the optical signal into a corresponding electric signal; the a/D conversion module 24 converts the analog electrical signal into a digital signal and transmits the digital signal to the central processing unit 26; the central processing unit 26 sends a light control instruction to the navigation aid light connected with the central processing unit through the output interface 23.

In an optional implementation manner of this embodiment, the accommodating box body is a sunken concentration box body, and is arranged in an underground space outside the taxiway; the communication module, the power supply cable, the optical cable, the monitoring unit of the single lamp and the power supply transformer of the single lamp are correspondingly placed in the sunken concentrated box body. Specifically, the submerged centralized box is connected with a power supply cable and an optical cable connected with the light station, and can also be provided with monitoring units of all single lamps, power supply transformers of all single lamps and power supply for each single lamp through the transformers.

Fig. 3 is a schematic layout diagram of a sunken concentrating box according to an embodiment of the invention. Each sunken type concentration box body 31 controls a plurality of surrounding single lamps (indicated by black dots), when the surrounding single lamps are not linearly arranged and have high density, the sunken type concentration box body which bears a one-to-many parallel communication function is adopted in the embodiment, and it needs to be explained that serial communication is not suitable in this case, so that the optical cable layout is complicated and circuitous, and the reconstruction cost is high.

Therefore, the technical scheme of the sunken type concentration box body adopted by the embodiment has the advantages that the sunken type concentration box body is convenient to install and maintain, the influence on the operation of the taxiway is greatly reduced, any plurality of control devices can be placed in a construction allowable range, any plurality of single lamps in a peripheral range are monitored, the existing situation of the centerline lights of the taxiway is not required to be changed, and the sunken type concentration box body is particularly suitable for the upgrading and updating transformation of the navigation aid lights of the normally operated airport.

In alternative implementations of the present embodiment, the navigational lights include center line lights and/or stop bank lights. The light control instruction of the navigation aid light comprises the following steps: sending switching and/or feedback commands to at least 45 of said groups of neutral lamps; and sending a switch command to at most 400 stop lights arranged at the periphery of the take-off and landing runway.

In an optional implementation manner of this embodiment, the parallel single-lamp control system issues a lamp control command through an optical cable bus, and can switch on and off the center line lamp group at least 10 times per second.

In an optional implementation manner of this embodiment, the parallel single-lamp control system issues a lamp control command through an optical cable bus, and can turn on and off the take-off and landing runway for at least 30 times per second after stopping the lights.

In an optional implementation manner of this embodiment, the parallel single-lamp control system issues a lamp control command through the optical cable bus, and can turn on and off the taxiway stop lights at least 65 times per second.

In an optional implementation manner of this embodiment, the parallel single-lamp control system issues the lamp control command through the optical cable bus, and can send at least 120 switching/feedback commands per second.

The light control instruction is designed for realizing the basic functions of safety, high efficiency, smoothness and no error of the whole airport scene operation, meets the control of the whole airport navigation light/single light under the A-SMGCS 4-level condition, and can realize the requirements after the PLC cable carrier communication technology is replaced by optical fiber transmission.

In summary, the parallel single-lamp control system based on optical fiber communication applied to airport navigation aid adopts optical fiber communication to replace the traditional power line carrier communication scheme, and can be well applied to navigation aid light guide systems with more than three levels of A-SMGCS. The invention has excellent performance on the system reaction time (even if the number of single loop single lamps is more than 200, the system reaction time is less than 1 second, and the invention meets the requirements of A-SMGCS grade 3 or grade 4); no special requirements are made on the aspects of the dimmer or the insulation of the whole loop and the like in terms of hardware; the installation aspect has low requirements on experience of installation personnel; the maintenance is simple and convenient. In addition, the sunken type concentration box body adopted by the invention is arranged in the underground space outside the taxiway, so that the influence on the ground taxiway is greatly reduced; because the control devices are connected in parallel, any plurality of control devices can be arranged within the construction allowable range; the invention does not need to change the existing situation of the taxi track centerline light, and is particularly suitable for the upgrading and updating transformation of the navigation aid light of the airport which is normally operated. Therefore, the application effectively overcomes various defects in the prior art and has high industrial utilization value.

Any person skilled in the art can modify or change the above-described embodiments without departing from the spirit and scope of the present application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of the present application.
