[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Ocean-going merchant ships, scientific research vessels, warships, etc., all need to be equipped with high-frequency communications, medium-frequency communications or satellite communications, so that they have the ability to communicate over long distances. Among them, high-frequency communications, medium-frequency communications or satellite communications all have long antennas to ensure the stability of their long-distance communications. However, an antenna that is too long will affect the movement of the ship. For example, when entering a low-altitude area, it is easy to hit obstacles, causing damage to the antenna.

[0032] The present invention provides an antenna lying device, which is intended to be able to switch the position of the antenna between a horizontal state and a vertical state to adapt to use on a water body.

[0033] See also Figures 1 to 7 In one embodiment of the present invention, the antenna lodging device 100 includes a device housing 1, a rotating mounting portion 2 and a driving mechanism 3; the rotating mounting portion 2 has a mounting end 21 and a connecting end 22 opposite to each other in a first direction, the mounting end 21 is for antenna installation, and the connecting end 22 can rotate relative to the device housing 1 along an axis extending in a second direction, so that the antenna can switch between a horizontal state and a vertical state, wherein the first direction and the second direction are two directions perpendicular to each other; the driving mechanism 3 is used to drive the connecting end 22 of the rotating mounting portion 2 to move.

[0034] The technical solution of the present invention adopts the setting of the driving mechanism 3 to provide power to the connecting end 22 of the rotating mounting portion 2, thereby driving the connecting end 22 to rotate. Through the setting of the mounting end 21, the antenna can be fixed at the mounting end 21, so that the antenna can be freely switched between the horizontal state and the vertical state, thereby meeting different usage requirements.

[0035] It is understandable that there are many ways to set up the drive mechanism 3, for example, it can be electric, pneumatic, hydraulic or manual. Please refer to the following description for the specific setting method.

[0036] Furthermore, in one embodiment, the antenna falling device 100 also includes a worm gear transmission mechanism 4, the worm gear transmission mechanism 4 includes a worm 42, a worm wheel 41 and a connecting shaft 43, the worm 42 is drivingly connected to the driving mechanism 3; the worm wheel 41 is meshingly connected to the worm 42; and one end of the connecting shaft 43 is passed through the worm wheel 41, and the other end of the connecting shaft 43 is fixedly mounted on the connecting end 22.

[0037] With such arrangement, the connecting shaft 43 can be more conveniently connected to the rotating mounting portion 2 , and the meshing arrangement of the worm wheel 41 and the worm 42 can provide different driving modes for the driving mechanism 3 , thereby improving flexibility.

[0038] Specifically, in an embodiment of an electric drive arrangement, the driving mechanism 3 is an electric driving mechanism, which includes a driving motor, and the driving motor is drivingly connected to the worm gear 42; the antenna falling device 100 also includes a control device, which is used to be installed on the hull, and the control device is electrically connected to the driving motor.

[0039] Such an arrangement, through the electric drive arrangement, has the effects of fast start-up acceleration, strong power, time saving and labor saving, etc., and can directly drive the worm 42 to rotate, thereby driving the worm wheel 41 to rotate, driving the connecting shaft 43 to rotate, so that the connecting end 22 rotates, driving the antenna to switch between the horizontal state and the vertical state, and achieving the purpose of lodging. Moreover, through the arrangement of the control device, different usage requirements of the drive motor can be controlled.

[0040] Considering the limited service life of the driving motor, in one embodiment, a speed reducer is further provided on the transmission link between the worm 42 and the driving motor.

[0041] With such a configuration, the reducer can improve the load capacity of the drive motor and reduce energy consumption, thereby protecting the drive motor.

[0042] In one embodiment, the drive motor includes a bidirectional permanent magnet DC motor.

[0043] In this configuration, a permanent magnet is used as an excitation source, and the bidirectional permanent magnet DC motor does not need to consume input power for excitation like a traditional motor, which can improve efficiency. And due to its simple and strong structure, the bidirectional permanent magnet DC motor has strong anti-vibration ability and is suitable for various complex working environments. At the same time, the bidirectional permanent magnet DC motor can meet different load and operation requirements.

[0044] In an embodiment of a manual drive setting, the driving mechanism 3 includes a rocker 31 and a gear transmission assembly 32, wherein the rocker 31 is arranged outside the device housing 1; the gear transmission assembly 32 includes a driving gear 321 and a driven gear 322, wherein the driving gear 321 is drivingly connected to the rocker 31, and the driven gear 322 is drivingly connected to the worm 42.

[0045] Such a configuration, by adopting a manual configuration, has an emergency effect and can adapt to different needs. Considering that there may be a power outage on the ship, the antenna lodging device 100 can still be used normally through a manual configuration. The driving gear 321 is rotated by the rocker 31, so that the driven gear 322 rotates to drive the worm 42 to rotate, so that the worm wheel 41 rotates to mobilize the rotating mounting part 2 to rotate, so as to switch the antenna between the horizontal state and the vertical state for lodging.

[0046] In order to improve the flexibility of the antenna lodging device 100, in one embodiment, the control device includes a main control unit, a power supply unit and a light key unit, the main control unit is used to be electrically connected to the driving motor; the power supply unit is used to be electrically connected to an external power supply and the main control unit; and the light key unit is used to be electrically connected to the main control unit.

[0047] With such a configuration, the main control unit, the power supply unit and the light key unit adopt a modular design, which is convenient for maintenance and replacement. When a component fails, there is no need to replace the entire control device, only the failed component needs to be replaced, which reduces maintenance costs. At the same time, this configuration method makes the control device highly flexible, and the functions and parameters of each unit can be adjusted according to actual needs to meet different application scenarios and requirements.

[0048] It should be added that the main control unit is also provided with a sensor switch quantity, a control interface and a communication interface for easy connection and use.

[0049] The power supply unit is mainly responsible for power input, and the light key unit is responsible for panel control and display.

[0050] In one implementation, the antenna lodging device 100 further includes a water immersion sensor, and the water immersion sensor is electrically connected to the main control unit.

[0051] With such a configuration, the water immersion sensor can monitor the water immersion around the antenna lodging device 100 in real time, ensuring that the device can still work normally in a humid or waterlogged environment, thereby reducing the possibility of equipment damage or performance degradation caused by water immersion.

[0052] It should be explained that the water immersion sensor is electrically connected to the main control unit and can transmit the detected water immersion signal to the main control unit in real time. The main control unit can perform corresponding processing according to the received signal, such as issuing an alarm message.

[0053] It is worth noting that the water immersion sensor can be implemented by means of a resistive sensor, a capacitive sensor or a conductive probe. Among them, when water contacts the resistive sensor, the resistance value will change, and by measuring the change in resistance, it can be determined whether there is water. The capacitive sensor uses the difference between the dielectric constant of water and air to change the capacitance value of the sensor, thereby detecting the presence of water. The conductive probe simply inserts two probes into a place where water may accumulate. If there is water, a current path will be formed between the probes, thereby outputting a corresponding electrical signal. It can be understood that when a ship is traveling on the water, the part that is in direct contact with the water is the bottom of the ship.

[0054] In one embodiment, a position detector is further provided on the device housing 1 , and the position detector is used to detect the position of the rotating mounting portion 2 .

[0055] In this way, the position of the rotating mounting part 2 can be monitored in real time by the in-position detector, so that it can accurately reach the preset target position during the movement. By detecting the position of the rotating mounting part 2, the in-position detector can send a signal to control the further action of the control device, thereby achieving precise control.

[0056] In one embodiment, a limiting portion is further provided on the device housing 1 to limit the movable stroke of the rotating mounting portion 2 .

[0057] With such arrangement, the movement of the rotating mounting portion 2 can be controlled by the limiting portion, so that the antenna can be switched between a horizontal state and a vertical state at will.

[0058] It can be understood that in this embodiment, there is no specific limitation on the arrangement of the limiting portion, for example, a limiting block is fixedly arranged on the device housing 1 .

[0059] In order to ensure the stability of the antenna during rotation and to adapt to the use requirements of different antenna installations, in one embodiment, two rotating mounting parts 2 are provided, and are respectively arranged at two opposite side ends of the device housing 1; a support plate 23 is provided at the mounting end portions 21 of the two rotating mounting parts 2, and a mounting bracket 24 is provided on the support plate 23, and the mounting bracket 24 is used for antenna installation.

[0060] In this way, the mounting bracket 24 can be supported by the support plate 23 , and the antenna can be installed and used through the mounting bracket 24 , and then the antenna can be rotated and used by rotating the rotating mounting portion 2 .

[0061] It is worth noting that in this embodiment, there is no specific limitation on the arrangement of the support plate 23 and the mounting bracket 24, which can be fixedly installed or movably installed.

[0062] Considering that there are many types of antennas, in order to adapt to the installation and use of different types of antennas, specifically, in one embodiment, the support plate 23 is detachably connected to the mounting end portions 21 of the two rotating mounting portions 2 .

[0063] With such arrangement, the support plate 23 and the mounting end portion 21 can be disassembled through the detachable connection, so as to facilitate replacement and flexible use.

[0064] It can be understood that in this embodiment, there is no specific limitation on the configuration of the detachable connection, such as bolt connection, screw connection, etc.

[0065] More specifically, in one embodiment, the mounting bracket 24 is detachably connected to the support plate 23 .

[0066] In this way, through the detachable connection of the mounting bracket 24 , different types of antennas can be replaced, installed and used, thereby improving the practicality of the antenna lodging device 100 .

[0067] It can be understood that in this embodiment, there is no specific limitation on the configuration of the detachable connection, such as bolt connection, screw connection, etc.

[0068] It should be added that a power supply and control cable interface is also provided on the device housing 1 to facilitate the device to be powered on and operate.

[0069] The present invention also provides a control method for an antenna inverting device, which includes an antenna inverting device 100. The specific structure of the antenna inverting device 100 refers to the above embodiment. Since the control method of the antenna inverting device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The control method of the antenna lodging device includes a control device, an antenna lodging device 100, a ship speed detection device, and a water immersion sensor. The control device is electrically connected to the antenna lodging device 100, the ship speed detection device, and the sensor, respectively. The control method also includes: See also Figure 8 , step S100: obtaining a ship speed detection signal output by the ship speed detection device and a water immersion detection signal output by the water immersion sensor; Step S200: Outputting an antenna control signal according to the ship speed detection signal and / or the water immersion sensor to switch the antenna between a horizontal state and a vertical state.

[0070] In this embodiment, the ship speed detection device can be implemented by a ship speed propeller frequency measuring instrument, an electromagnetic speed meter, etc. Among them, the ship speed propeller frequency measuring instrument is a sensor system based on single-chip microcomputer control, which can estimate the ship speed according to the rotation speed of the propeller. When the ship is stationary, the sensor output is zero; once it starts to move, the corresponding ship speed can be calculated based on the rotation speed. The electromagnetic speed meter measures the ship speed by sensing the electromotive force generated when the water flows through the sensor. It can be understood that both the ship speed detection signal output by the ship speed detection device and the water immersion detection signal output by the water immersion sensor are corresponding electrical signals. The control module receives the corresponding voltage signal and obtains the ship speed of the ship after analog-to-digital conversion, as well as whether there is water seepage at the bottom of the ship.

[0071] Further, refer to Fig. 9 The step of outputting an antenna control signal according to the ship speed detection signal and / or the water immersion sensor so as to switch the antenna between the horizontal state and the vertical state specifically includes: Step S210: when the ship speed corresponding to the ship speed detection signal is greater than a first preset ship speed, outputting an antenna horizontal control signal to make the antenna enter a horizontal state; Step S220: when the ship speed corresponding to the ship speed detection signal is greater than a first preset ship speed and the signal corresponding to the water immersion detection signal does not confirm contact with liquid, output an antenna horizontal control signal to make the antenna enter a horizontal state; Step S230: When the ship speed corresponding to the ship speed detection signal is less than the first preset ship speed, and the signal corresponding to the water immersion detection signal confirms contact with liquid, output an antenna vertical control signal to put the antenna into a vertical state.

[0072] In this embodiment, when the control device receives the water immersion detection signal to confirm that water seepage occurs at the bottom of the vessel, the control device will further determine whether the speed of the vessel meets the requirement of switching the antenna from the horizontal state to the vertical state by receiving the speed detection signal output by the speed detection device, so as to avoid the antenna from breaking due to its long length when the ship speed is high. Therefore, by setting the first preset ship speed, it is confirmed that the antenna will not be damaged when switching from the horizontal state to the vertical state when the ship speed is below the first preset ship speed. Among them, when the antenna is in the vertical state, the control device confirms whether the speed of the vessel is greater than the first preset ship speed through the speed detection signal output by the speed detection device. When the speed of the vessel is greater than the first preset ship speed, the control device will output the corresponding antenna horizontal control signal to the antenna retracting device 100, so that the antenna retracting device 100 controls the antenna to switch from the vertical state to the horizontal state. It can be understood that the direction of change of the antenna retracting device 100 controlling the antenna to switch from the vertical state to the horizontal state is opposite to the direction of the ship's forward travel, so as to further avoid the antenna from being damaged due to wind resistance. Further, when the ship speed corresponding to the ship speed detection signal is greater than the first preset ship speed, and the signal corresponding to the water immersion detection signal is not confirmed to be in contact with liquid, the control device will also output the corresponding antenna horizontal control signal to the antenna inverting device 100, so that the antenna inverting device 100 controls the antenna to switch from a vertical state to a horizontal state. When the ship speed corresponding to the ship speed detection signal is less than the first preset ship speed, and the signal corresponding to the water immersion detection signal is confirmed to be in contact with liquid, the control device will output an antenna vertical signal to the antenna inverting device 100, so that the antenna inverting device 100 controls the antenna to switch from a horizontal state to a vertical state. Among them, when the ship speed is greater than the first preset ship speed, and the signal corresponding to the water immersion detection signal is confirmed to be in contact with liquid, the control device will output a prompt signal through the host computer to enable the ship's management personnel to reduce the ship speed. When the ship speed is lower than the first preset ship speed, the control device will output an antenna vertical signal to the antenna inverting device 100, so that the antenna inverting device 100 controls the antenna to switch from a horizontal state to a vertical state.

[0073] In this embodiment, the state of the vessel at this time is judged by using the water immersion detection signal output by the water immersion sensor arranged at the bottom of the vessel to confirm whether the vessel currently has water seepage and other problems. When the water immersion detection signal output by the water immersion sensor confirms that the vessel has water seepage problems, the control device will further receive the ship speed detection signal output by the ship speed detection device to confirm whether the current speed of the vessel is suitable for controlling the antenna inversion device 100 to control the antenna to switch from a horizontal state to a vertical state, thereby avoiding damage to the antenna due to excessive ship speed. It is understandable that when a ship has problems such as water seepage, the information of the problem needs to be quickly transmitted to the ship management personnel, so that the ship management personnel can promptly check the area of ​​the corresponding water immersion sensor, and transmit the information to the emergency personnel on the shore through the antenna, so as to facilitate timely rescue. Through this detection control method, the time required for the relevant message to be transmitted to the emergency personnel on the shore can be effectively reduced, and the stability of the antenna communication is also ensured.

[0074] refer to Fig.10 In one embodiment of the present invention, the control method of the antenna lodging device further includes a host computer, the control device includes a data processing module, and the host computer is communicatively connected with the data processing module; before the step of obtaining the ship speed detection signal output by the ship speed detection device and the water immersion detection signal output by the water immersion sensor, the method further includes: Step S300: Acquire serial port communication data output by multiple serial port devices of different types, and convert the multiple serial port communication data into IP communication data according to a preset configuration program and output; Step S400: Acquire IP communication data outputted from the cloud, and convert the IP communication output into serial communication data of multiple different types of serial port devices according to a preset configuration program and output the data; Among them, the preset configuration program is an editable script program corresponding to the ship speed detection device and the water immersion sensor; the serial port device includes the antenna lodging device 100, the ship speed detection device and the water immersion sensor.

[0075] It should be understood that in the antenna lodging control system, multiple devices are usually included, and there is a cooperative working relationship between the multiple devices. For example, the antenna lodging control system includes devices with different interfaces such as the antenna lodging device 100, the ship speed detection device, and the water immersion sensor. Therefore, it is necessary to set a set of control devices in the antenna lodging device 100 to achieve close cooperation between the various devices. In addition, in the antenna lodging device 100, each device also needs to establish a communication connection with the external terminal through the control device. The control device collects the operating data of each device and outputs it to the external terminal. In addition, the control device can also obtain the control instructions issued by the external terminal and output them to the corresponding device so that the device performs the corresponding action.

[0076] However, the communication connection between the control device and each device usually adopts a wired connection method of serial communication, while the communication connection established with the external terminal is a wireless connection method through IP communication. In addition, there are many different types of serial port data collected by the control device, and different types of serial port data will cause errors in the integrated control device when summarizing and outputting the information to the external terminal. For example, temperature may be expressed in Celsius or Fahrenheit, and voltage may be in Volt, and their data packet structures (such as start bit, end bit, check bit, etc.) may be different depending on the application scenario. This also means that if the control device needs to pre-process the collected data, it needs to apply the corresponding parsing rules according to the specific format of the received serial port data. This means that for temperature and voltage data, the control device may need to configure different parsing logic or parameters to correctly identify and format these data.

[0077] With the development of information technology, the communication system on board ships has gradually shifted from traditional analog and dedicated digital networks to IP-based network architecture. This shift enables shipboard systems to more easily integrate various modern services and technologies. Through satellite communications, radio signals, or using cellular networks when the ship is close to the coast, the ship can establish an IP connection with a land base station. This allows the crew to send emails, access the Internet, transfer files, and conduct video conferences. Computers, servers, navigation equipment, radars, automatic identification systems, ship management systems, and other electronic control systems on board can be connected through a local area network and use the IP protocol to exchange information. For example, the bridge can monitor the engine status or cargo loading and unloading in real time. Among them, the ship is usually equipped with a variety of devices that require data feedback and receive data control, and the required devices are serial port devices, such as antenna lodging devices 100, ship speed detection devices, water immersion sensors and other serial port devices, and different types of serial port devices may have different formats for the serial port communication data fed back to the control device. In order to realize data communication between the serial port device and the host computer, it is necessary to convert the serial port data output by the serial port device into IP communication data so that the host computer can effectively obtain the data output by the serial port device. Therefore, the conversion of serial communication data into IP communication data needs to be based on the corresponding communication protocol to facilitate the correct conversion of data, thereby enabling multiple different types of serial port devices to establish communication connections with the host computer through the control device. The host computer obtains the IP communication data output by the control device to confirm the working status of each serial port device. It is understandable that the above data conversion process will be implemented by the data processing module in the control device.

[0078] In this embodiment, when multiple serial port devices (antenna lodging device 100, ship speed detection device, water immersion sensor, etc.) generate data, the control device will collect these data through its serial port communication module (such as RS232, RS485 or RS422), and these data are usually encoded in a specific serial communication protocol format, such as MODBUS, TCP / IP over Serial, etc., and then the data processing module in the control device executes the corresponding programmable script program to convert these serial port communication data formats into IP data packets that can be transmitted on the Internet. This process includes data encapsulation, that is, the original data is packaged according to the requirements of the TCP / IP protocol, which includes adding IP headers, TCP / UDP headers, etc., to ensure the addressing, routing and transmission of data in the network, so that it can be sent to the host computer through an IP communication module (such as 2G, 3G, 4G, 5G or Wi-Fi). Among them, in order to ensure the security of data transmission, the control device can support various security measures, such as SSL / TLS encryption, VPN tunnel technology, etc., to encrypt the IP data packets to be sent to prevent the data from being stolen or tampered with during transmission. In addition, the control device can also implement a confirmation mechanism for data transmission according to application requirements, such as the TCP ACK mechanism, to ensure reliable transmission of data packets. If no confirmation is received, the control device can automatically retransmit the data packet.

[0079] In this embodiment, the control device continuously monitors or waits for IP data packets sent from the host computer through an IP communication module (such as 4G, 5G, etc.). When a data packet arrives, the control device first receives and processes the data. The control device decapsulates the received IP data packet, removes the network layer and transport layer packaging such as the IP header, TCP or UDP header, and extracts the original payload data. If the data is encrypted, the control device will also perform a decryption operation. The data processing module in the control device executes an editable script program to convert the decapsulated data into a format suitable for serial port transmission. This may involve adjustment of the data format, instruction parsing, error checking, etc. to ensure the correctness and integrity of the data. After the conversion is completed, the control device sends the data to the corresponding serial port device through a serial port communication module (RS232, RS485, RS422, etc.), thereby achieving the purpose of remote control or configuration. In the process of serial port communication data output, the control device needs to implement a flow control mechanism to ensure that the data transmission rate does not exceed the maximum transmission capacity of the serial port, and at the same time handle possible transmission errors, such as parity errors, timeout retransmission, etc. In addition, the control device will also report the status of data transmission to the data center through the network, such as successful reception confirmation, error report, etc., to achieve communication synchronization and management between the two parties.

[0080] Among them, the editable script file can be implemented by, for example, JavaScript programming language or lua programming language. In order for the data processing module in the control device to effectively execute the editable script file, it is necessary to configure the corresponding parsing program. For example, when the editable script program adopts JavaScript programming language, an embedded JavaScript engine needs to be used; when the editable script program adopts lua programming language, the virtual machine needs to use Lua interpreter, so as to realize the conversion of the code in the editable script program into machine code or instructions that can be directly executed by the control device CPU. By adopting a virtual machine compatible with the editable script file, the data processing module in the control device can effectively execute various instructions of the editable script file. Compared with C / C++ firmware that needs to be compiled, the editable script program can be directly loaded, modified and executed immediately on the control device without recompiling the entire firmware, which greatly shortens the cycle from modification to testing, thereby achieving the technical effect of rapid deployment work. In addition, the scripting language supports dynamic types and advanced data structures, which provides more convenience for processing complex logic and data, making it easier for the device to adapt to diverse business scenarios. For example, in an antenna lodging control system, when it is necessary to increase or decrease the number of input serial port devices, it is only necessary to add or delete the editable script program corresponding to the serial port device to ensure communication between the serial port device and the host computer.

[0081] In one embodiment of the present invention, the antenna lodging device 100 includes a horizontal limit switch and a vertical limit switch, the horizontal limit switch is used to output a horizontal switch signal when triggered, and the vertical limit switch is used to output a vertical switch signal when triggered. The specific steps for switching the antenna between a horizontal state and a vertical state are: Upon receiving the horizontal switch signal, confirming that the antenna is in a horizontal state and stopping further movement of the antenna; When the vertical switch signal is received, it is confirmed that the antenna is in a vertical state, and further movement of the antenna is stopped.

[0082] In this embodiment, the horizontal limit switch and the vertical limit switch can be implemented by a limit detection switch, a photoelectric detection component, an image detection component, etc. Among them, the limit detection switch is taken as an example, and the limit detection switch includes a horizontal limit switch and a vertical limit switch respectively. By setting the horizontal limit switch and the vertical limit switch at the vertical boundary and the horizontal boundary of the antenna inversion device 100 respectively. When the antenna inversion device 100 pushes the antenna inversion base to move to the vertical boundary or the horizontal boundary, the horizontal limit switch and the vertical limit switch will be triggered by the antenna inversion base, thereby outputting a horizontal switch signal or a vertical switch signal, so that the control circuit in the antenna inversion device controls the antenna inversion base to stop moving from the horizontal to the vertical direction or controls the antenna inversion base to stop moving from the vertical to the horizontal direction. By setting the horizontal limit switch and the vertical limit switch, the antenna inversion base can stably move between the vertical boundary and the horizontal boundary, avoiding the antenna inversion damage caused by the extrusion of the antenna inversion base and the movement boundary due to excessive movement.

[0083] In one embodiment of the present invention, after the step of confirming that the signal corresponding to the water immersion detection signal is in contact with liquid, the method includes: The water immersion detection signal is converted into IP communication data according to a preset configuration program and output to a host computer; The host computer outputs a prompt signal according to the IP communication data.

[0084] In this embodiment, the control device establishes a communication connection with the water immersion sensor through a serial communication module, and executes a corresponding programmable script program through the data processing module in the control device to convert the serial communication data format into IP communication data that can be transmitted on the Internet, so that the host computer can still accurately obtain the water immersion detection signal output by the water immersion sensor under the condition that it is not connected to the control device by wired communication, so that the host computer can confirm whether it is necessary to output a corresponding prompt signal according to the detection signal. Optionally, the control device can also obtain the detection result by processing the water immersion detection signal in advance, and convert the detection result into IP communication data and output it to the host computer, so that the host computer can directly confirm whether it is necessary to control the prompt circuit to output the prompt signal through the detection result. Among them, the prompt circuit can be implemented by a voice prompt circuit or a visual prompt circuit. Further, when the host computer receives the IP communication data and confirms that the information corresponding to the water immersion detection signal is a water seepage problem at the bottom of the ship according to the IP communication data, the host computer will control the prompt circuit to output the corresponding prompt signal, so that the management personnel of the ship can make corresponding inspections and processing in time.

[0085] It should be supplemented that, in an embodiment of the present invention, the control method of the antenna lodging device 100 further includes a positioning device. After the step of confirming that the signal corresponding to the water immersion detection signal is in contact with liquid, the method includes: After the antenna enters a vertical state, the positioning device outputs a positioning signal via the antenna.

[0086] In this embodiment, the positioning device can be implemented by a satellite navigation receiver, an inertial navigation device, etc. Among them, a satellite navigation receiver is one of the most commonly used positioning methods for modern ships. For example, GPS receives signals from satellites in the earth's orbit and uses time signals from multiple satellites to calculate the position of the ship. China's Beidou satellite navigation system can also provide high-precision positioning services and can be used worldwide. After the antenna enters the vertical state, the positioning device can output a positioning signal to the emergency personnel on the shore through the antenna, so as to confirm with the ship management personnel in time whether to provide emergency rescue work.

[0087] The present invention also proposes a control device, the control device comprising: a memory, a processor, and an antenna lodging device 100 control program stored in the memory and running on the processor, the antenna lodging device 100 control program being configured to implement the steps of the control method of the antenna lodging device 100 as described in any one of the above. It is worth noting that since the control device of the present invention is based on the control method of the antenna lodging device 100 described above, the embodiments of the control device of the present invention include all technical solutions of all embodiments of the control method of the antenna lodging device 100 described above, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0088] The present invention also proposes an antenna retracting system, which includes an antenna retracting device 100, a ship speed detection device, a water immersion detection device, a positioning device, a host computer, and the control device as described above. It is worth noting that since the antenna retracting system of the present invention is based on the above-mentioned control device, the embodiments of the antenna retracting system of the present invention include all technical solutions of all embodiments of the above-mentioned control device, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0089] In an embodiment of the present invention, the antenna lodging device 100 further includes a waterproof structure.

[0090] It is understandable that in the technical solution of the present application, the antenna lodging device 100 is used on ships. Therefore, the antenna lodging device 100 needs to have IP67 waterproof capability to avoid damage to the circuit therein. Among them, the waterproof structure can use high-quality rubber sealing rings or O-rings to form a tight seal at moving parts such as hinges, shafts, etc., to ensure that moisture cannot penetrate through these parts. In addition, waterproof glue is used to seal between fixed joint surfaces (for example, between the base and the housing) to prevent water from entering through the gaps. For the electrical connection part, specially designed waterproof connectors should be used. These connectors can prevent moisture from intrusion while maintaining electrical connection.
