[0001] The present invention relates to the technical field of civil aviation equipment monitoring and management, and in particular to a centralized monitoring system for air traffic control equipment. Background Art

[0002] Currently, domestic civil airports involve many different types of air traffic control equipment. Due to the scale of the airports, the number of each type of air traffic control equipment is extremely large. Therefore, in the existing technology, air traffic control equipment is generally monitored and managed separately according to its field of use and location. This makes the management of air traffic control equipment difficult and extremely consumes the human resources of management personnel. This not only causes great work pressure on air traffic control equipment maintenance personnel and management personnel, but may even affect the flight safety of aircraft. Summary of the Invention

[0009] The VHF communication device is connected to the air traffic control equipment data acquisition unit via the VHF data acquisition unit;

[0010] The relay machine is connected to the air traffic control equipment data collection unit through the relay data collection unit.

[0011] Compared with the prior art, the centralized monitoring system for air traffic control equipment of the present invention utilizes the air traffic control equipment data acquisition unit to obtain various data of the local navigation data acquisition components, local radar stations, very high frequency communication devices, and relay machines through the navigation data acquisition unit, radar data acquisition unit, very high frequency data acquisition unit, and relay data acquisition unit of the centralized monitoring cabinet. Then, the air traffic control equipment data acquisition unit transmits the obtained various data to the centralized monitoring equipment network through the centralized monitoring server. The centralized monitoring equipment network then transmits the obtained various data to the centralized monitoring terminal, so that the administrator can centrally monitor and manage the air traffic control equipment, thereby strengthening the maintenance and management of the air traffic control equipment, alleviating the pressure on equipment maintenance personnel and management personnel, and ensuring the flight safety of aircraft.

[0012] In one embodiment, the local navigation data acquisition component includes a DVOR / DME navigation station, a beacon data acquisition unit and several optical terminals.

[0024] When the remote terminal device enters the LAN coverage of the centralized monitoring device LAN through the entrance and exit, the second low-frequency wake-up receiver and the first low-frequency wake-up receiver are woken up in sequence, the network switching module switches the connection object to the centralized monitoring device LAN, and connects to the control signal switch through the centralized monitoring device LAN, and the network switching module shuts down and locks the mobile communication network.

[0025] According to the setting direction order of the first low-frequency transmission band and the second low-frequency transmission band and the wake-up order of the second low-frequency wake-up receiver and the first low-frequency wake-up receiver, it can be determined that the remote terminal device has entered the local area network coverage range of the centralized monitoring device local area network, thereby driving the network switching module to connect to the control signal switch through the centralized monitoring device local area network.

[0056] The remote terminal device is connected to the centralized monitoring device network 24 or the centralized monitoring device local area network, wherein the remote terminal device is provided with a first low-frequency wake-up receiver, a second low-frequency wake-up receiver, and a network switching module; in response to the wake-up order of the first low-frequency wake-up receiver and the second low-frequency wake-up receiver, the network switching module switches the connection object from the centralized monitoring device network 24 and the centralized monitoring device local area network;

[0057] See also Figure 4 The access management device 9 includes a first low-frequency transmission band 91 and a second low-frequency transmission band 92. The first low-frequency transmission band 91 and the second low-frequency transmission band 92 are arranged in parallel at the entrance and exit of the local area network coverage range of the centralized monitoring device local area network. When the remote terminal device passes through the first low-frequency transmission band 91, the first low-frequency wake-up receiver is awakened; when the remote terminal device passes through the second low-frequency transmission band 92, the second low-frequency wake-up receiver is awakened.

[0058] Since the centralized monitoring equipment LAN is limited in coverage, a first low-frequency transmission band 91 and a second low-frequency transmission band 92 are set at the entrance and exit of the LAN coverage. According to the order in which the remote terminal device passes through the first low-frequency transmission band 91 and the second low-frequency transmission band 92, the network switching module switches the connection object from the centralized monitoring equipment network 24 and the centralized monitoring equipment LAN, so that the administrator who enters the LAN coverage can connect to the control signal switch through the centralized monitoring equipment LAN, and the administrator who leaves the LAN coverage can connect to the control signal switch through the centralized monitoring equipment network 24, avoiding all patrolling administrators from obtaining monitoring data through one server, reducing the operating pressure of a single server when transmitting monitoring data, and also improving the operating efficiency and practical life of the server.

[0059] In a feasible embodiment, the first low-frequency transmission band 91 and the second low-frequency transmission band 92 are sequentially arranged in a direction away from the LAN coverage range of the centralized monitoring device LAN;

[0060] When the remote terminal device enters the LAN coverage of the centralized monitoring device LAN through the entrance and exit, the second low-frequency wake-up receiver and the first low-frequency wake-up receiver are woken up in sequence, the network switching module switches the connection object to the centralized monitoring device LAN, and connects to the control signal switch through the centralized monitoring device LAN, and the network switching module shuts down and locks the mobile communication network.

[0067] For example, when the remote terminal device leaves the LAN coverage of the centralized monitoring device LAN through the entrance and exit, the second low-frequency wake-up receiver and the first low-frequency wake-up receiver are woken up in sequence, and the network switching module switches the connection object to the centralized monitoring device network 24. The network switching module unlocks and starts the mobile communication network, connects to the centralized monitoring device network 24 through the mobile communication network, and connects to the control signal switch through the centralized monitoring device network 24.

[0068] In this embodiment, based on the setting direction order of the first low-frequency transmission band 91 and the second low-frequency transmission band 92 and the wake-up order of the second low-frequency wake-up receiver and the first low-frequency wake-up receiver, it can be determined that the remote terminal device has left the local area network coverage of the centralized monitoring device local area network, thereby driving the network switching module to connect to the control signal switch through the centralized monitoring device network 24.
