Description

Technical Field

[0001] The utility model relates to the field of remote control of air traffic management equipment, and particularly relates to a remote control system for an aviation marker beacon. Background Art

[0002] The civil aviation communication, navigation and surveillance system mainly includes three parts: communication, navigation and surveillance, providing accurate, timely, continuous and reliable communication, navigation and surveillance services for civil aviation activities. Among them, the navigation equipment provides flight positioning and guidance information for aircraft through radio, including providing navigation services at airport terminals, en-route and airway.

[0003] Currently, with the continuous expansion and increasing perfection of the construction scale of air traffic management equipment, its computer room equipment is relatively scattered and requires long-term on-site personnel, which greatly increases the investment in manpower and material resources. How to timely reflect the equipment operation status, real-time collect equipment status data, and have functions such as remote control and abnormal alarm has become an urgent problem to provide decision-making support for the decision-making level.

[0004] In air traffic equipment, the marker beacon is a ground radio equipment in the aviation navigation system. It belongs to a very high frequency radio beacon in aviation navigation and is usually used in combination with the instrument landing system to provide a determined position in the flight route. The marker beacon is generally divided into outer marker beacon, middle marker beacon and inner marker beacon.

[0005] Generally speaking, at the airport terminal, the equipment computer room of the marker beacon is set on the extension line of the airport runway.

The involved remote control is based on the remote device data monitoring and control of the centralized monitoring system, including application scenarios such as computer room management, oil and gas pipelines, highways, power environments, and video monitoring. The remote control of the marker beacon involves the integrated application of technologies such as modulation and demodulation, signal conversion, signal transceiver and forwarding.

The signal therein is a copper cable signal and is transmitted through a telephone line. In the promotion of the centralized monitoring project of air traffic management equipment, using a telephone line to transmit a copper cable signal has weak anti-interference ability.

[0058] Embodiment 2

[0059] A remote control system for an aviation marker beacon, and the whole process of remote control - status signal feedback is carried out in this embodiment.

[0060] First, a remote control operation is performed. The remote control unit generates a remote control signal, and the generated remote control signal is in the form of an FSK signal. The remote control signal is input into the first protection module.

[0061] The first protection module filters other DC signals in the remote control signal to prevent the DC electricity generated at the control end from affecting the subsequent multiplexing equipment. The filtered remote control signal is input into the first multiplexing module through an RJ45 line signal.

[0062] The first multiplexing module, in which the FSK - E1 electrical signal conversion device converts the filtered remote control signal from an FSK signal to an E1 electrical signal, and the converted signal is transmitted into the optical terminal through the switch. The optical terminal converts the E1 electrical signal into a remote control signal in the form of an optical signal, which is transmitted into the second multiplexing module through an optical fiber.

[0063] The second multiplexing module, in which the optical terminal converts the remote control signal in the form of an optical signal into an E1 electrical signal, and the converted signal is sent into the FSK - E1 electrical signal conversion device through the switch, and is converted into the restored remote control signal, which is input into the second protection module through an RJ45 line signal.

[0064] The restored remote control signal is a signal in FSK format.

[0065] The second protection module is used to prevent the DC voltage generated by the voltage restoration module from flowing back to the second multiplexing module, directly outputting the restored remote control signal. When performing remote startup, it cannot complete the startup alone. It requires ±28V voltage to be applied to both ends of the relay in the control circuit of the marker beacon simultaneously. After the relay is attracted, a circuit is formed, and only then can the power supply of the marker beacon be turned on.

[0066] Therefore, the voltage restoration module generates ±28V voltage and outputs the signal to the marker beacon. When the restored remote control signal is input into the marker beacon, it acts together with the ±28V voltage to successfully remotely control the startup of the marker beacon.

[0067] The ±28V voltage generated by the voltage restoration module is always applied to the marker beacon. When the startup signal of the remote control signal is input into the marker beacon, the marker beacon starts up. When performing other remote control operations, the ±28V voltage is only applied to the marker beacon, only ensuring that the marker beacon is in the startup state, and then performing shutdown and switching operations, without acting together with other remote control signals except the startup command.

[0068] After the marker beacon receives the restored remote control signal and ±28V voltage, the device starts up. At this time, the marker beacon will generate a status signal and transmit the status signal back. The generated status signal is a signal in FSK format, which does not contain DC signals. The status signal is input into the second protection module.

[0069] The second protection module is used to prevent the voltage generated by the voltage restoration module from flowing back to the second multiplexing module, and directly inputs the status signal into the second multiplexing module through the RJ45 line signal.

[0070] The second multiplexing module, where the FSK-E1 electrical signal conversion device converts the status signal from FSK signal to E1 electrical signal, and transmits it into the optical terminal through the switch, converts the E1 electrical signal into the status signal in the form of optical signal, and transmits it into the first multiplexing module through the optical fiber.

[0071] The first multiplexing module, where the optical terminal converts the status signal in the form of optical signal from optical signal to E1 electrical signal, sends it into the FSK-E1 electrical signal conversion device through the switch, converts it into the restored status signal, and inputs it into the first protection module through the RJ45 line signal.

[0072] The restored status signal is a signal in FSK format.

[0073] Then, through the first protection module, the restored status signal is directly sent into the remote control unit.

[0074] The remote control unit receives the restored status signal, and after demodulation, the current status of the marker beacon is displayed on the front panel. Thus, the entire process of remote control - status signal feedback ends.

[0075] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
