It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The application discloses an experimental device for detecting the influence of environmental factors on animal navigation behavior, which is fixed on a migrating animal, for example, fixed on the animal by a fixing device, such as a ring or a belt, or implanted in subcutaneous tissue of the animal, for example, in the form of a chip. The device is used for collecting and recording environmental factor information in the animal migration process. By analyzing the information, the information of the key environmental factors influencing the navigation of the animal is found out.

As shown in fig. 1, according to one embodiment of the present application, the experimental apparatus includes an environmental detection sensor 10, an animal behavior sensor 20, an information recording module 30, a central processing module 40, a time base module 50, a communication module 60, and a drop-off device 70. Each module is described in detail below.

The environment detection sensor 10 is used for detecting environmental factors during animal migration, and may include, for example, a vision sensor, a temperature sensor, a salinity sensor, a wind direction sensor, a pressure sensor, a geomagnetic sensor, and the like. Wherein the content of the first and second substances,

the visual sensor is used for acquiring an image of the environment around the animal, and dynamic or static sampling can be adopted to record the visual image in the process of animal migration.

The temperature sensor is used to record the ambient temperature during the migration of the animal. Alternatively, with discrete sampling, the sampling period is related to the animal species and its behavior, which can range from hours to tens of minutes.

The salinity sensor is used for recording the salinity of the animals in the migration process, is mainly suitable for marine animals, and has a sampling period related to the species and the behaviors of the animals ranging from hours to tens of minutes. Alternatively, a fixed frequency sampling mode may be used.

The wind direction sensor is used for recording the wind direction of the animals in the process of migration and is mainly suitable for birds. Alternatively, real-time sampling may be employed and the apparent wind direction transition times and locations recorded.

The pressure sensor is used to record the air or water pressure in the environment of the animal migrating. The pressure sensor may take different forms and ranges depending on the animal species.

The geomagnetic sensor is used for recording the geomagnetic direction in the animal migration environment. Alternatively, sampling and recording of the sampled data may be performed at a fixed frequency.

It will be appreciated by those skilled in the art that the above-described sensors may be selected according to the actual requirements, e.g. the species of animal, the environment during migration, etc. Meanwhile, in addition to the sensors, other environmental sensors can be added according to specific requirements so as to detect environmental factor parameters related to animal migration. For example, for bird experiments, the environment detection sensors include a vision sensor, a temperature sensor, a wind direction sensor; corresponding to a land animal experiment, the environment detection sensor comprises a vision sensor, a temperature sensor, a wind direction sensor and a geomagnetic sensor; for marine animal experiments, the environment detection sensors comprise a vision sensor, a temperature sensor, a salinity sensor, a pressure sensor and the like.

The animal behavior sensor 20 is used for detecting the animal behavior posture, such as the direction, speed and the like of the movement, in the migration movement process. For example, a direction sensor, an acceleration sensor, a landmark orientation module, etc. may be included.

Wherein the content of the first and second substances,

the direction sensor is used for detecting the advancing direction of the animal and takes the geographic coordinates as reference.

The acceleration sensor is used for detecting the advancing speed and the advancing acceleration of the animal and accumulating to obtain the advancing distance. The sensor samples and records sampling data in an XYZ three-axis space.

The landmark orientation module, which may be, for example, a compass, a GPS or other positioning module, is configured to provide geographic coordinates as reference coordinates for experiments.

The information recording module 30 is used for storing the sampling information of the environment detection sensor 10 and the animal behavior sensor 20. Alternatively, the information recording module 30 may be a Micro memory card, a Micro SD card, or a flash chip.

The central processing module 40 is connected to the environment detecting sensor 10 and the animal behavior sensor 20, and is configured to acquire sampling information of the sensors, perform preprocessing on the sampling information by using an embedded program, such as filtering, interference removal, and the like, and store the preprocessed data in the information recording module 30. Alternatively, the central processing module 40 may adopt an embedded processor, such as a single chip microcomputer.

The time base module 50 is connected to the central processing module 40 and is used to provide time coordinates for information collection and recording. Alternatively, relative time or absolute time may be used, as desired for the experiment.

In the present application, the central processing module 40 forms a storage data structure according to (T, P, D) of the collected information according to the data of the time base module 50 and the landmark orientation module, where T represents the current time of information collection, P represents the current orientation of information collection, and D represents the data of the collected information.

The communication module 60 is connected to the central processing module 40, and is configured to transmit the data stored in the information recording module 30 to the server 100 at a predetermined cycle by wireless transmission. For example, data in the information recording module 30 is transmitted to the server at predetermined time intervals, or when the remaining storage space in the information recording module 30 is less than a predetermined value, the data is transmitted to the server.

In addition, since the movement track of the animal is difficult to be accurately determined, and strong wireless transmission signal strength may not be always maintained in some areas, the communication module 60 detects the wireless transmission signal strength and transmits the data in the information recording module 30 to the server when the strength is higher than a predetermined value.

Optionally, the communication module 60 employs iridium communication or a mobile communication link for data wireless transmission.

The server 100 receives the data sent by the experimental device, analyzes the data by using a built-in analysis algorithm, and determines environmental factors influencing animal migration navigation.

Because the animal movement track is unpredictable, under specific conditions, such as conditions that the collected information meets the analysis requirement, the electric quantity is about to be exhausted, the sensor is damaged, the wireless transmission signal is continuously weak, and the like, the falling device 70 is used for falling the experimental device from the animal body, so that the experimental personnel can conveniently check the experimental device.

The falling-off device is a micro mechanical device, and the experimental device is fixed on the mechanical device and is fixed to a part of the animal body through the mechanical device, such as a foot ring, a neck ring and the like.

Alternatively, the test device may be adhered to the appropriate part of the animal's body using a naturally aged adhesive, and naturally released from the animal's body after a predetermined time.

In order to facilitate the experimenter to find the experimental device quickly, the dropout device 70 further comprises a beacon 71. The beacon 71 may be a wireless signal generator, and may emit radio waves intermittently, so that experimenters may search for experimental devices.

For the experiment of marine animals, corresponding experimental apparatus can provide certain buoyancy, makes experimental apparatus can float in the surface of water after the animal body falls off.

Those skilled in the art will appreciate that the experimental set-up also includes a power supply for providing operating voltages to the various sensors and modules. The power source may be a primary battery, a rechargeable capacitor, or a solar cell, etc.
