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.

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 series-connection type 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 an navigation aid light guide system 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; in the aspect of hardware requirements, no special requirements are made on aspects such as lamps and related hardware, the quality of a lamp transformer, a dimmer or the insulation of the whole circuit and the like; in the aspect of installation, the optical fiber standard installation specification is met, and the experience requirement on installation personnel is not high; in the aspect of maintenance, the operation and the maintenance are convenient.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In this embodiment, the single-lamp control units 12 are connected by communication via the optical cable line 15, instead of using a PLC power carrier communication scheme in the prior art, and because the system response time of the optical fiber communication is excellent and the requirements on hardware, installation, maintenance and the like of an airport are not strict, the system can be well applied to a navigation light guidance system with more than three levels of a-SMGCS. In addition, in the present embodiment, the individual lamp control units 12 perform serial communication through an optical cable line, for example, the structure diagram shown in fig. 1, and the optical cable line 15 passes through the individual lamp control units one by one and performs serial communication; because the channel is many in the airport, and a lot of channels are rectangular shape moreover, and the lamp accuse system of rectangular shape channel is applicable to the series communication, and it can realize to assign the lamp accuse instruction by the system through the optical cable circuit, convenient management and maintenance.

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 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 series single-lamp control system issues the lamp control command through the optical cable line, 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 series single-lamp control system issues the lamp control command through the optical cable line, 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 serial 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; in the aspect of hardware requirements, no special requirements are made on aspects such as lamps and related hardware, the quality of a lamp transformer, a dimmer or the insulation of the whole circuit and the like; in the aspect of installation, the optical fiber standard installation specification is met, and the experience requirement on installation personnel is not high; in the aspect of maintenance, the operation and the maintenance are convenient.
