Description

Technical Field

[0001] This invention relates to the field of wildlife monitoring technology, and in particular to an energy-saving method and device for monitoring bird vital signs. Background Technology

[0002] When studying wild birds, it is necessary to collect and analyze their vital signs data. In order to obtain the vital signs data of the research subjects without affecting their normal lives, they are usually released after being fitted with mobile monitoring devices. The monitoring devices are then used to collect relevant information about the birds and transmit it wirelessly to a receiving station for analysis and research.

[0003] Due to the small size and poor load-bearing capacity of birds, the size and weight of monitoring devices are severely limited, thus only small-capacity batteries can be used. However, once wild birds are released, they are difficult to recapture, making battery replacement and recharging impossible. This means that the normal operating time of battery-powered monitoring devices is very short. Bird monitoring is a long-term research project, and to extend the normal operating time of monitoring equipment, current technology typically uses solar panels to charge the batteries, thereby extending the power supply. However, monitoring devices are often worn on the neck, abdomen, or legs of birds, and the solar panels are often blocked by the body of the research subject or vegetation, making it difficult to receive direct sunlight for extended periods. Therefore, the battery charging efficiency is low, resulting in the monitoring devices remaining in a state of constant power shortage. Under such power shortage conditions, how to optimize energy conservation and minimize unnecessary power consumption is a major challenge in the development and advancement of monitoring devices.

[0004] Ornithological research often focuses on specific environments or specific bird activities. For example, studies on the high-altitude flight of bar-headed geese only require collecting vital sign data at an altitude of approximately 9,000 meters. Similarly, studies on the breeding patterns of bar-headed geese only require collecting vital sign data during mating. However, current monitoring devices continuously monitor bird vital signs, resulting in the acquisition of a large amount of useless information during non-required periods and wasting energy. This method of vital sign monitoring not only wastes data processing resources but also severely limits the uptime of monitoring equipment. Therefore, there is an urgent need for an energy-efficient vital sign monitoring method tailored to the specific monitoring target of birds, as well as a corresponding vital sign monitoring device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an energy-saving method and device for monitoring bird vital signs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An energy-saving method for monitoring vital signs in birds includes the following steps: Step A1: Obtain motion information and / or flight altitude information of the monitored object; Step A2: Initiate or deactivate vital signs monitoring based on motion information and / or flight altitude information.

[0008] As a further improvement to the above technical solution: The step A1 of obtaining the motion information of the monitored object includes the following steps: Step A11: Obtain the measured triaxial acceleration values; Step A12: Compare the measured triaxial acceleration values ​​with the standard triaxial acceleration values, and infer the motion information of the monitored object based on the comparison results.

[0009] The method for determining the standard triaxial acceleration value includes the following steps: Step B1: Simultaneously acquire motion images and measured triaxial acceleration values ​​of the monitored object; Step B2: Identify the motion type of the monitored object based on the motion images; Step B3: Extract and mark the measured triaxial acceleration values ​​corresponding to each motion type as the standard triaxial acceleration values ​​for that motion type.

[0010] Obtaining flight altitude information in step A1 includes the following steps: Step A13: Obtain the measured air pressure value; Step A14: Calculate the air pressure error caused by wing flapping based on the motion information of the monitored object; Step A15: Calculate the actual air pressure value based on the measured air pressure value and the air pressure error, and then calculate the flight altitude information based on the actual air pressure value.

[0011] Step A14 includes the following steps: Step A141: Identify the wingbeat frequency based on the motion information; Step A142: Obtain the corresponding standard wing-beating air pressure value based on the wing-beating frequency; this is the air pressure error.

[0012] The method for determining the standard flapping air pressure value includes the following steps: Step C1: Under known air pressure conditions, simultaneously acquire motion images and air pressure fluctuation values ​​of the monitored object; Step C2: Identify the wingbeat frequency of the monitored object based on the motion images; Step C3: Extract and mark the air pressure fluctuation value corresponding to each wing-beating frequency, and use it as the standard wing-beating air pressure value for that wing-beating frequency.

[0013] Then, the present invention discloses an energy-saving bird vital signs monitoring device for implementing the above-mentioned energy-saving bird vital signs monitoring method, comprising: a data acquisition unit for acquiring motion information and / or flight altitude information of the monitored object, as well as vital signs information; a communication unit for receiving control commands and transmitting information data; a main control unit for data processing and analysis; and a power supply unit for providing power to the data acquisition unit, the communication unit, and the main control unit; wherein the main control unit is signal-connected to the data acquisition unit, the communication unit, and the power supply unit respectively, and the power supply unit is electrically connected to the data acquisition unit, the communication unit, and the main control unit respectively.

[0014] As a further improvement to the above technical solution: The acquisition unit includes a three-axis accelerometer for acquiring motion information of the monitored object, the motion information including at least one of motion type, motion amount and wingbeat frequency; and / or a barometric pressure sensor for acquiring flight altitude information of the monitored object; and a photoelectric sensor for acquiring vital signs information of the monitored object, the vital signs information including at least one of respiratory rate, heart rate and blood oxygen concentration.

[0015] Compared with the prior art, the advantages of the present invention are as follows: By continuously collecting motion and altitude information of the monitored object and comparing it with thresholds, vital sign monitoring is initiated when the motion and / or altitude information reaches the activation threshold and terminated when the threshold is reached. This allows for the control of vital sign monitoring using motion and altitude information. In other words, vital sign monitoring in this solution only occurs when preset conditions are met. When these conditions are met, it indicates that the monitored object is in a state of investigation, ensuring that the collected vital sign information is within the effective timeframe. Compared to existing methods that continuously collect vital sign information, this solution not only saves data processing resources but also conserves energy and extends the normal operating time of the monitoring equipment.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1 The energy-saving bird vital sign monitoring method of this embodiment includes the following steps: Step A1: Obtain motion information of the monitored object; Step A2: If the motion information reaches the activation threshold, then activate vital sign monitoring. Step A3: If the motion information reaches the stopping threshold, then stop monitoring vital signs.

[0019] In the technical solution disclosed in this embodiment, motion information of the monitored object is continuously collected, and the collected motion information is continuously compared with a threshold. When the motion information reaches the activation threshold, vital sign monitoring is initiated; when the motion information reaches the deactivation threshold, vital sign monitoring is deactivated. This enables the control of the start and stop of vital sign monitoring using motion information. In other words, in this technical solution, vital sign monitoring is only performed when preset conditions are met. When the preset conditions are met, it indicates that the monitored object is in a state awaiting investigation, thus ensuring that the collected vital sign information is within the effective time period. Compared to existing monitoring methods that continuously collect vital sign information of monitored objects, this technical solution not only saves data processing resources but also saves electricity and helps extend the normal operating time of the monitoring equipment.

[0020] In this embodiment, obtaining the motion information of the monitored object in step A1 includes the following steps: Step A11: Obtain the measured triaxial acceleration values; Step A12: Compare the measured triaxial acceleration values ​​with the standard triaxial acceleration values, and infer the motion information of the monitored object based on the comparison results.

[0021] Specifically, the method for determining standard triaxial acceleration values ​​includes the following steps: Step B1: Simultaneously acquire motion images and measured triaxial acceleration values ​​of the monitored object; Step B2: Identify the motion type of the monitored object based on the motion images; Step B3: Extract and mark the measured triaxial acceleration values ​​corresponding to each motion type as the standard triaxial acceleration values ​​for that motion type.

[0022] Birds exhibit regular movement patterns. We first use sensors worn on their bodies to acquire their current triaxial acceleration values ​​during a specific movement, and then correlate these values ​​with that particular movement. When monitoring birds, if similar or identical triaxial acceleration values ​​are obtained, we can infer that the monitored bird is performing a movement corresponding to that value.

[0023] Example 2 The energy-saving bird vital sign monitoring method of this embodiment includes the following steps: Step A1: Obtain the flight altitude information of the monitored object; Step A2: If the flight altitude information reaches the activation threshold, then activate life sign monitoring; Step A3: If the flight altitude information reaches the stop threshold, then stop monitoring for life signs.

[0024] In the technical solution disclosed in this embodiment, flight altitude information of the monitored object is continuously collected, and the collected flight altitude information is continuously compared with a threshold. When the flight altitude information reaches the activation threshold, vital sign monitoring is initiated; when the flight altitude information reaches the deactivation threshold, vital sign monitoring is deactivated. This enables the control of the start and stop of vital sign monitoring using flight altitude information. In other words, in this technical solution, vital sign monitoring is only performed when preset conditions are met. When the preset conditions are met, it indicates that the monitored object is in a state of investigation, thus ensuring that the collected vital sign information is within the effective time period. Compared with existing monitoring methods that continuously collect vital sign information of monitored objects, this technical solution not only saves data processing resources but also saves electricity and helps extend the normal operating time of the monitoring equipment.

[0025] In this embodiment, obtaining flight altitude information in step A1 includes the following steps: Step A13: Obtain the measured air pressure value; Step A14: Calculate the air pressure error caused by wing flapping based on the motion information of the monitored object; Step A15: Calculate the actual air pressure value based on the measured air pressure value and the air pressure error, and then calculate the flight altitude information based on the actual air pressure value.

[0026] Further, step A14 includes the following steps: Step A141: Identify the wingbeat frequency based on the motion information; Step A142: Obtain the corresponding standard wing-beating air pressure value based on the wing-beating frequency; this is the air pressure error.

[0027] Furthermore, the method for determining the standard flapping pressure value includes the following steps: Step C1: Under known air pressure conditions, simultaneously acquire motion images and air pressure fluctuation values ​​of the monitored object; Step C2: Identify the wingbeat frequency of the monitored object based on the motion images; Step C3: Extract and mark the air pressure fluctuation value corresponding to each wing-beating frequency, and use it as the standard wing-beating air pressure value for that wing-beating frequency.

[0028] Generally, atmospheric pressure decreases with increasing altitude. Within a 3000-meter range, atmospheric pressure decreases by approximately 133 Pa for every 12 meters of elevation gain. By obtaining the atmospheric pressure of the environment in which a monitoring object is located, its altitude can be deduced. However, birds need to generate updrafts through wingbeats to maintain flight, and the airflow disturbances caused by wingbeats alter the atmospheric pressure, resulting in data corruption. To obtain more accurate altitude data, the influence of wingbeats needs to be eliminated during the analysis of atmospheric pressure data. Under known atmospheric pressure conditions, we first use sensors worn on a bird's body to obtain the current measured atmospheric pressure value during flight. Under the influence of wingbeats, this measured atmospheric pressure value will fluctuate with the wingbeat movement. Simultaneously, the wingbeat frequency is recorded through imaging, and this wingbeat frequency is correlated with the atmospheric pressure fluctuation value for calibration. This atmospheric pressure fluctuation value is the standard wingbeat pressure value at the corresponding wingbeat frequency. When monitoring birds, the wingbeat frequency of the monitored object is obtained through motion information, and the corresponding standard wingbeat pressure value is retrieved in sequence. The actual air pressure value can be calculated by using the measured air pressure value and the standard wingbeat air pressure value, and the flight altitude information can be obtained by deducing from the actual air pressure value.

[0029] Example 3 The energy-saving bird vital sign monitoring method of this embodiment includes the following steps: Step A1: Obtain the motion information and flight altitude information of the monitored object; Step A2: If the motion information and / or flight altitude information reach the activation threshold, then activate vital sign monitoring; Step A3: If the motion information and / or flight altitude information reach the stop threshold, then stop monitoring for vital signs.

[0030] In this embodiment, obtaining the motion information of the monitored object in step A1 includes the following steps: Step A11: Obtain the measured triaxial acceleration values; Step A12: Compare the measured triaxial acceleration values ​​with the standard triaxial acceleration values, and infer the motion information of the monitored object based on the comparison results.

[0031] In this embodiment, the method for measuring standard triaxial acceleration values ​​includes the following steps: Step B1: Simultaneously acquire motion images and measured triaxial acceleration values ​​of the monitored object; Step B2: Identify the motion type of the monitored object based on the motion images; Step B3: Extract and mark the measured triaxial acceleration values ​​corresponding to each motion type as the standard triaxial acceleration values ​​for that motion type.

[0032] In this embodiment, obtaining flight altitude information in step A1 includes the following steps: Step A13: Obtain the measured air pressure value; Step A14: Calculate the air pressure error caused by wing flapping based on the motion information of the monitored object; Step A15: Calculate the actual air pressure value based on the measured air pressure value and the air pressure error, and then calculate the flight altitude information based on the actual air pressure value.

[0033] In this embodiment, step A14 includes the following steps: Step A141: Identify the wingbeat frequency based on the motion information; Step A142: Obtain the corresponding standard wing-beating air pressure value based on the wing-beating frequency; this is the air pressure error.

[0034] In this embodiment, the method for determining the standard wing-beating pressure value includes the following steps: Step C1: Simultaneously acquire motion images and measured air pressure values ​​of the monitored object; Step C2: Identify the wingbeat frequency of the monitored object based on the motion images; Step C3: Extract and mark the measured air pressure value corresponding to each wing-beating frequency as the standard wing-beating air pressure value for that wing-beating frequency.

[0035] In the technical solution disclosed in this embodiment, motion information and flight altitude information of the monitored object are continuously collected, and the collected motion information and flight altitude information are continuously compared with thresholds. When the motion information and / or flight altitude information reach the activation threshold, vital sign monitoring is initiated; when the motion information and / or flight altitude information reach the deactivation threshold, vital sign monitoring is deactivated. This enables the control of the start and stop of vital sign monitoring using motion information and flight altitude information. In other words, in this technical solution, vital sign monitoring is only performed when preset conditions are met. When the preset conditions are met, it indicates that the monitored object is in a state of investigation, thus ensuring that the collected vital sign information is within the effective time period. Compared with existing monitoring methods that continuously collect vital sign information of monitored objects, this technical solution not only saves data processing resources but also saves electricity and helps extend the normal operating time of monitoring equipment.

Or / and a barometric pressure sensor used to acquire flight altitude information of the monitored object; And photoelectric sensors for acquiring vital signs information of the monitored object, including at least one of respiratory rate, heart rate and blood oxygen concentration.

In other words, in this technical solution, vital sign monitoring only occurs when preset conditions are met.
