Further, in other embodiments, step S3 includes: judging whether the navigational speed of the ship belongs to a first speed level or not; if so, setting the AIS device to be in a second working mode, wherein the AIS device has a second transmitting frequency; judging whether the navigational speed of the ship belongs to a second speed level or not; if so, setting the AIS device to be in a third working mode, wherein the AIS device has a third transmitting frequency; judging whether the navigational speed of the ship belongs to a third speed level or not; if so, setting the AIS device to a fourth operating mode in which the AIS device has a fourth transmit frequency; the navigational speed of the first speed level is lower than the navigational speed of the second speed level, the navigational speed of the second speed level is lower than the navigational speed of the third speed level, the second transmitting frequency is lower than the third transmitting frequency, and the third transmitting frequency is lower than the fourth transmitting frequency.

Existing AIS equipment typically includes lithium batteries and solar panels, the capacity of which is limited by the size of the AIS equipment. Under the condition of limited lithium battery capacity, in order to prolong the service time of the electric quantity of the lithium battery, the embodiment of the invention analyzes the current state of the ship, namely the working environment and the working state of the AIS equipment through various sensors, and further controls the working mode of the AIS equipment according to the analysis result to achieve the aim of saving electricity.

Fig. 2 is a schematic composition diagram of an AIS device according to an embodiment of the present invention. As shown in fig. 2, the AIS apparatus includes: the lithium battery and the solar panel are used for supplying power to the AIS equipment; the volume sensor is used for detecting volume information of the environment; the vibration sensor is used for detecting the vibration frequency of the environment; the positioning module is used for acquiring navigation information of the ship, judging whether the running state of the ship is navigation or berthing according to the navigation information, and determining the navigation speed of the ship when the ship navigates; the processor is used for acquiring the volume information and the vibration frequency and judging whether the engine of the ship is started or not according to a preset volume threshold and a preset vibration frequency threshold; specifically, whether the sound volume is larger than a preset sound volume threshold and the vibration frequency is larger than a preset vibration frequency threshold is judged, if yes, the engine is determined to be in a starting state; otherwise, the engine is determined to be in the off state, and other circuit devices except the volume sensor, the vibration sensor and the processor of the AIS equipment are enabled to be in the sleep mode, such as the positioning module is enabled to be in the sleep mode. Preferably, the audio threshold is set according to the starting volume of the ship engine, and the vibration frequency threshold is set according to the vibration characteristic value of the ship engine. Preferably, the vibration characteristic value of the engine is extracted by a previously established model.

In a further embodiment, the processor further obtains the driving status and the speed of the vessel from the positioning module when the engine is started, and sets the AIS equipment to a first operating mode having a first transmitting frequency when the engine is started and the vessel is in a stopped state; when the engine is started and the ship is in a sailing state, the operating modes of the AIS equipment are set according to the speed level to which the ship speed belongs, different speed levels correspond to different operating modes, and the AIS equipment has different transmitting frequencies under the different operating modes, wherein the different transmitting frequencies are all larger than the first transmitting frequency.

Because the ship engine has certain vibration frequency and noise when being started, whether the engine is started or not can be judged by combining a vibration threshold and a noise threshold by utilizing the vibration sensor and the volume sensor. And when the volume sensor detects that the current volume is larger than a preset volume threshold value, namely a noise threshold value, and the vibration sensor detects that the current vibration is larger than a preset vibration frequency threshold value, determining that the engine of the ship is in a starting state. Generally, when a ship is on the sea, the frequency of the ship swing is determined by the wave frequency. The vibration frequency is the frequency of sea waves when the ship is parked, and is below 1 Hz. Illustratively, the selected shock sensor may detect shock frequencies above 20 Hz. Preferably, the threshold value for the vibration frequency is 60HZ and the volume threshold value, i.e. the noise threshold value, is 55 db. The corresponding vibration frequency threshold and volume threshold can be set according to the performance and noise of the specific engine, and the corresponding vibration sensor and volume sensor can be selected. Further, when the engine is judged not to be started, other parts of the AIS except the volume sensor, the vibration sensor and the processor are made to enter a sleep state, wherein the other parts comprise a positioning module and other peripheral circuits; and when the engine is judged to be started, the positioning module is awakened. Therefore, the positioning module and some peripheral circuits do not need to be in working states all the time, and the power saving effect of the AIS equipment is improved.

In fig. 3, compared to the embodiment shown in fig. 2, the AIS apparatus further includes: the brightness sensor is arranged on the solar panel, can sense the position of illumination and is used for detecting the brightness of the environment; the processor is connected with the brightness sensor and used for judging whether the current day or night is the daytime or the night according to the brightness information detected by the brightness sensor; setting the working mode of the AIS equipment according to the speed level of the navigational speed of the ship in the daytime or at night; wherein, for the same speed level: the AIS device is configured to operate in different modes with different frequencies of transmission during the day and at night, with the frequency of transmission during the day being higher than the frequency of transmission during the night.

Fig. 4 is a flowchart illustrating a method for controlling the AIS device according to this embodiment. In this embodiment, as shown in fig. 4, it is determined whether the engine is started or shut down by the vibration sensor and the volume sensor in the AIS device. If the engine is off, the AIS device is set to a sleep mode and the AIS does not transmit. If the engine is started, the positioning module is used for continuously judging whether the ship is in a sailing state or a parking state currently. If the vessel is moored, the AIS equipment is set to the working mode 5: the AIS transmission frequency was once 6 minutes. For example, the positioning module determines whether the ship is currently in a sailing state or a berthing state according to the displacement of the ship, and further determines the current sailing speed of the ship. If the ship is in a sailing state, further judging whether the current ship is in the daytime or at night through a brightness sensor; different working modes are set in the day and at night according to the speed of the same level, and different AIS transmitting frequencies are used. Illustratively, during the daytime, when the speed is above 10 knots, the AIS equipment is set to operating mode 1: the AIS emission frequency is 5 seconds; when the navigational speed is 6-10 knots, the AIS equipment is set to be in the working mode 2: the AIS emission frequency is once in 10 seconds; when the navigational speed is 2-6 knots, the AIS equipment is set to be in a working mode 3: the AIS transmit frequency is once every 30 seconds. At night, when the navigational speed is more than 10 knots, the AIS equipment is set to be in an operating mode 2: the AIS emission frequency is 10 seconds; when the navigational speed is 6-10 knots, the AIS equipment is set to be in the working mode 3: the AIS emission frequency is once every 30 seconds; when the navigational speed is 2-6 knots, the AIS equipment is set to be in the working mode 4: the AIS transmission frequency was once for 1 minute. It follows that AIS is transmitted less frequently when the vessel is at a transmitter off or the speed is at a lower speed level. By using the method of the embodiment of the invention, the power saving of the AIS equipment is realized by identifying the state of the ship, the transmitting frequency of the AIS equipment can be reduced when the ship is parked or approaches the shore, and the transmitting frequency at night is lower than that in the daytime for the same speed level, so that the power consumption of the AIS equipment is saved, and the normal running of the ship is not influenced.

In the prior art, the AIS is transmitted at least once every 6 minutes, so that the AIS equipment is normally transmitted at least 240 times (1 transmission per 6 minutes) for 1 day when the ship is even in a berthed state. By using the method of the embodiment of the invention, after the actual state of the ship is comprehensively judged, the ship is launched for 24 times (1 time in 1 hour) in 1 day under the berthing state, and the power consumption can be saved by 10 times. Furthermore, in the prior art, the positioning module needs to work all the time to monitor whether the navigational speed of the ship changes, but the scheme of the invention judges the starting state of the ship engine by adopting the vibration sensor and the volume sensor, and does not need the positioning module to work all the time. When the engine of boats and ships is not started, the location module can be in sleep mode, and other working circuit also can be in sleep state or outage state this moment, and from this, the AIS equipment can further save electricity.

Of course, in a specific implementation, the speed may be divided into more or less levels according to needs, corresponding operating modes may be set according to different levels, and AIS transmission frequencies of corresponding values may be set according to the operating modes.

In one specific implementation, the processor is connected with the sensors of the AIS equipment, acquires information of the sensors, and determines the state of the ship according to the acquired information of the sensors, namely, judges whether an engine of the ship is turned on or off; whether the vessel is underway or moored; how much the speed is; whether daytime or evening at present, then set up the different mode of AIS equipment correspondingly for the AIS is in different transmission frequency, from this when boats and ships berth or land, reduces the transmission frequency of AIS, thereby realizes the power saving of AIS equipment.
