Description

Technical Field

[0001] The present invention belongs to the field of communication technology, in particular to the field of wireless communication network technology, and specifically relates to a remote communication system and a communication method. Background Art

[0002] The sea area is relatively wide, and the communication signal between the sea and the land is poor and unstable. If there is a danger such as people falling into the water or the ship taking on water, it is difficult to ensure a stable communication connection with the land management and rescue personnel, which makes it difficult for the rescue personnel to quickly and accurately find the location of the danger. If a high-performance communication module is directly installed on the distress device installed on the personnel or the ship, a large amount of electricity will be consumed when the device is turned on, which is difficult to maintain for a long time. The time-consuming rescue at sea is also long and cannot meet the needs.

[0003] Therefore, based on the above technical problems, it is necessary to design a new remote communication system and communication method. Summary of the invention

[0004] The object of the present invention is to provide a remote communication system and a communication method.

[0005] In order to solve the above technical problems, the present invention provides a remote communication system, comprising:

[0006] Mobile terminals, host computers and several marine communication devices;

[0007] The water communication device is set in the sea area, and the water communication device communicates with other water communication devices when set, and each water communication device records the signal strength of the communication with other water communication devices;

[0008] After the mobile terminal falls into the water, the mobile terminal communicates with the water communication device. After the mobile terminal establishes communication with the water communication device, the water communication device sends the information sent by the mobile terminal to the host computer, and establishes communication between the host computer, the water communication device and the mobile terminal.

[0009] Further, the mobile terminal includes: a terminal processor, a terminal low-power Bluetooth module and a trigger switch;

[0010] The trigger switch is electrically connected to the terminal processor;

[0011] The terminal low-power Bluetooth module is electrically connected to the terminal processor;

[0012] After the trigger switch contacts water, the terminal low-power Bluetooth module is started, and a communication signal is sent to the water communication device through the terminal low-power Bluetooth module.

[0013] Furthermore, the mobile terminal further comprises: a terminal sound and light module, a terminal communication module, a terminal positioning module and a plurality of terminal water immersion sensors electrically connected to the terminal processor;

[0014] The terminal positioning module is adapted to obtain location information of the mobile terminal;

[0015] The terminal sound and light module is suitable for sound and light alarm;

[0016] The terminal water immersion sensor is suitable for detecting the immersion of a person or object on which the mobile terminal is installed;

[0017] The terminal processor is suitable for sending the location information and the flooding condition to the water communication device through the terminal communication module.

[0018] Furthermore, when the mobile terminal is set on a life buoy on a person, when the person falls into the water, the low-power Bluetooth module of the terminal is activated and sends a trigger message to the water communication device immediately;

[0019] When the mobile terminal is set on the hull, when the hull is flooded, the low-power Bluetooth module of the terminal is started and sends a trigger message of a preset time length to the water communication device.

[0020] Furthermore, the above-water communication device includes: a low-power processor, a high-performance processor and a plurality of buoy low-power Bluetooth modules;

[0021] The buoy low-power Bluetooth module is electrically connected to the low-power processor module;

[0022] The low power consumption processor is electrically connected to the high performance processor;

[0023] The buoy low-power Bluetooth module is suitable for receiving information sent by the terminal low-power Bluetooth module of the mobile terminal;

[0024] The buoy low-power Bluetooth module starts a high-performance processor after receiving the information;

[0025] The high-performance processor is electrically connected to the low-power Bluetooth module.

[0026] Furthermore, the above-water communication device further comprises: a high-performance antenna, a buoy sound and light module, a buoy positioning module and a buoy communication module electrically connected to the high-performance processor;

[0027] The buoy positioning module is suitable for obtaining the position information of the water communication device;

[0028] The buoy sound and light module is suitable for sound and light alarm;

[0029] The high-performance processor is adapted to receive the location information and water immersion condition of the mobile terminal sent by the terminal communication module through the buoy communication module;

[0030] The high-performance processor is suitable for sending the location information of the mobile terminal, the water immersion condition and the location information of the water communication device to the host computer through the buoy communication module.

[0031] Furthermore, the high-performance processor is started after the low-power processor receives the trigger information sent by the mobile terminal through the buoy low-power Bluetooth module.

[0032] Furthermore, after being started, the high-performance processor sends a feedback signal to the low-power processor. If the low-power processor does not receive the feedback signal, it is determined that the high-performance processor fails to start. At this time, the buoy low-power Bluetooth module sends a trigger message to another water communication device with the strongest communication signal with the water communication device, and the other water communication device starts the corresponding high-performance processor until the high-performance processor of the water communication device is successfully started.

[0033] When the water communication device is set up, it communicates with other water communication devices and sorts the communication signal strength from high to low. When the high-performance processor of the water communication device fails to start, the trigger information is forwarded in the order of the communication signal strength from high to low.

[0034] Furthermore, after the high-performance processor is started, the high-performance processor receives the signal sent by the terminal low-power Bluetooth module of the mobile device through the buoy low-power Bluetooth module, and determines the situation of the sea area where the mobile device is located according to the signal.

[0039] After the mobile terminal falls into the water, the mobile terminal communicates with the water communication device. After the mobile terminal establishes communication with the water communication device, the water communication device sends the information sent by the mobile terminal to the host computer, and establishes communication between the host computer, the water communication device and the mobile terminal.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0050] Embodiment 1, as Figures 1 to 5 As shown, this embodiment 1 provides a remote communication system, including: a mobile terminal, a host computer and several water communication devices; the water communication device is set in the sea area, and the water communication device communicates with other water communication devices when set, and each water communication device records the signal strength of communication with other water communication devices; after the mobile terminal falls into the water, the mobile terminal communicates with the water communication device, and after the mobile terminal and the water communication device establish communication, the water communication device sends the information sent by the mobile terminal to the host computer, and establishes communication between the host computer, the water communication device and the mobile terminal; when a person falls into the water or a ship sinks in the sea area, long-term stable communication is established to facilitate timely and accurate rescue. The water communication device can be set on a buoy or other device.

[0051] In this embodiment, the mobile terminal includes: a terminal processor, a terminal low-power Bluetooth module and a trigger switch; the trigger switch is electrically connected to the terminal processor; the terminal low-power Bluetooth module is electrically connected to the terminal processor; the terminal low-power Bluetooth module is started after the trigger switch contacts water, and a communication signal is sent to the water communication device through the terminal low-power Bluetooth module; the terminal low-power Bluetooth module has lower consumption, which can increase the maintenance time of the mobile terminal; the trigger switch will be started after contacting water; the mobile terminal can be set on a life jacket, and when a person falls into the water, the trigger switch in the mobile terminal on the life jacket is triggered after contacting sea water, and communication can be established with the water communication device at the first time, and stable and long-term communication can be established with the host computer via the water communication device, so that rescue personnel can carry out rescue in a timely and accurate manner.

[0052] In this embodiment, the mobile terminal also includes: a terminal sound and light module, a terminal communication module, a terminal positioning module and several terminal water immersion sensors electrically connected to the terminal processor; an antenna can be provided on the mobile terminal to increase the signal strength; the terminal positioning module is suitable for obtaining the location information of the mobile terminal; the terminal sound and light module is suitable for sound and light alarm; the terminal water immersion sensor is suitable for detecting the water immersion of a person or object with a mobile terminal installed; the terminal processor is suitable for sending the location information and water immersion condition to the water communication device through the terminal communication module. The terminal communication module uses bandwidth for communication, and has certain distance range requirements; the terminal positioning module can be a GPS module, which obtains the location information of the mobile terminal through satellite communication, and can accurately obtain the location information of the person after the person falls into the water; the terminal communication module can adopt Ethernet communication, 5G and other communication methods. These communication methods are affected by the bandwidth. The range is limited. If only this type of communication is used in the sea area, it is difficult to establish stable and long-term communication with the host computer corresponding to the rescue personnel and management personnel; the terminal water immersion sensor can be set at different positions to facilitate the judgment of the person falling into the water. For example, the terminal water immersion sensor is set at the chest, waist and other positions of the person. When the water immersion sensor is immersed in water for a long time, it will send a signal. At this time, it can be judged that the corresponding part of the person is immersed in water; the terminal sound and light module can facilitate rescue personnel to find people who have fallen into the water.

[0053] In this embodiment, when the mobile terminal is set on a lifebuoy on a person, the low-power Bluetooth module of the terminal is started and sends a trigger message to the water communication device as soon as possible after the person falls into the water; when the mobile terminal is set on the hull, the low-power Bluetooth module of the terminal is started and sends a trigger message of a preset time length to the water communication device after the hull is flooded; the hull may accidentally infiltrate water, so the trigger signal sent when the mobile terminal is installed on the hull is for a period of time, which is convenient for the crew to cancel the false triggering.

[0054] In this embodiment, the water communication device includes: a low-power processor, a high-performance processor and several buoy low-power Bluetooth modules; the buoy low-power Bluetooth module is electrically connected to the low-power processor module; the low-power processor is electrically connected to the high-performance processor; the buoy low-power Bluetooth module is suitable for receiving information sent by the terminal low-power Bluetooth module of the mobile terminal; the buoy low-power Bluetooth module starts the high-performance processor after receiving the information; the high-performance processor is electrically connected to the low-power Bluetooth module; the low-power processor and the buoy low-power Bluetooth module remain in a triggered state, and due to the low power consumption, they can be used for a long time, so that communication can be established as soon as someone falls into the water or the ship is submerged. An antenna can be set on the water communication device to increase the coverage range of the buoy low-power Bluetooth module.

[0055] In this embodiment, the water communication device also includes: a high-performance antenna, a buoy sound and light module, a buoy positioning module and a buoy communication module electrically connected to the high-performance processor; the buoy positioning module is suitable for obtaining the location information of the water communication device; the buoy sound and light module is suitable for sound and light alarm; the high-performance processor is suitable for receiving the location information and water immersion condition of the mobile terminal sent by the terminal communication module through the buoy communication module; the high-performance processor is suitable for sending the location information, water immersion condition of the mobile terminal and the location information of the water communication device to the host computer through the buoy communication module; the buoy communication module can adopt Ethernet communication, 5G and other methods, and the high-performance antenna can greatly amplify the performance and range of the buoy communication module; the buoy sound and light module can assist rescue personnel in locating people who have fallen into the water or dangerous areas.

[0056] In this embodiment, the high-performance processor is started after the low-power processor receives the trigger information sent by the mobile terminal through the buoy low-power Bluetooth module; normally, the high-performance processor and other devices are in a turned-off state, which reduces consumption and increases the maintenance time of the low-power processor and the buoy low-power Bluetooth module.

[0057] In this embodiment, the high-performance processor sends a feedback signal to the low-power processor after being started. If the low-power processor does not receive the feedback signal, it is determined that the high-performance processor fails to start. At this time, the buoy low-power Bluetooth module sends a trigger message to another water communication device with the strongest communication signal with the water communication device, and the other water communication device starts the corresponding high-performance processor until the high-performance processor of the water communication device is successfully started.

[0058] When the water communication device is set up, it communicates with other water communication devices, and sorts the communication signal strength from high to low. When the high-performance processor of the water communication device fails to start, the trigger information is forwarded in the order of the communication signal strength from high to low; ensuring that when the first water communication device that establishes communication is damaged, it can quickly match the second water communication device; after the high-performance processor is started, the low-performance processor is turned off, and at this time the location information of the mobile terminal is sent to the buoy communication module through the terminal communication module. The high-performance processor can send its own location information and the location information of the mobile device to the host computer through the buoy communication module. The rescue personnel and management personnel at the host computer can communicate with the fallen person through the terminal communication module and the buoy communication module, and know the status of the fallen person at the first time, so as to arrange the corresponding rescue method and rescue task. The terminal communication module and the buoy communication module have strong communication capabilities and can meet the needs of voice communication; the terminal communication module can send the detection results of the immersion sensor to the host computer through the buoy communication module, so that the management personnel can know the corresponding situation in time.

[0059] In this embodiment, after the high-performance processor is started, the high-performance processor receives the signal sent by the terminal low-power Bluetooth module of the mobile device through the buoy low-power Bluetooth module, and determines the situation of the sea area where the mobile device is located based on the signal; the high-performance processor can determine the situation of the sea area where the person who fell into the water is located based on the signal received by the buoy low-power Bluetooth module. If the sea area where the person who fell into the water is located has strong winds and waves, the terminal low-power Bluetooth module on the mobile terminal may be repeatedly submerged by sea water, resulting in the inability to send continuous signals. The high-performance processor can determine the wind and wave conditions of the corresponding sea area based on the intermittent signals, and adjust the rescue method in time.

[0060] In this embodiment, after the high-performance processor is started, communication is established through the terminal communication module and the buoy communication module, and communication is established with the host computer through the buoy communication module; the signal communication strength is enhanced by the high-performance antenna, and long-term and stable communication is established between the person who falls into the water and the host computer.

[0061] In this embodiment, the terminal communication module and the buoy communication module enable the staff at the host computer to establish voice communication with the person who falls into the water.
