Description

This invention relates to a data acquisition device, a program, and a data acquisition method. Conventional techniques for identifying the activity status of animals being kept in captivity are known. Examples of such techniques can be found in Patent Documents 1 and 2. Patent Document 1 describes a technique for identifying animal abnormalities from time-series animal observation data and individual animal information. Patent Document 2 describes a technique for obtaining rules regarding the state and behavior of animals from time-series data. Patent No. 6096738Patent No. 6057786 This is a schematic diagram illustrating the overall configuration of a data collection system in one embodiment of the present invention.This is a block diagram illustrating the configuration of the hardware and functional blocks of a sensor device in one embodiment of the present invention.This is a block diagram illustrating the configuration of the hardware and functional blocks of a data acquisition device in one embodiment of the present invention.This graph shows the results of an additive model used to identify the periodicity of activity levels over time periods using a data acquisition device in one embodiment of the present invention.This flowchart shows an example of a data acquisition process performed by a data acquisition device in one embodiment of the present invention. The present invention will be described below with reference to the accompanying drawings, in accordance with its embodiments. However, the present invention is not limited to the embodiments described below. Furthermore, the figures referenced in the following description merely provide a schematic representation of the shape, size, and positional relationships to the extent necessary to understand the content of this disclosure. In other words, the present invention is not limited to the shapes, sizes, and positional relationships illustrated in the figures. (Embodiment) <Data Collection System S> Figure 1 is a schematic diagram illustrating the overall configuration of a data collection system S in one embodiment of the present invention. As shown in Figure 1, the data collection system S of this embodiment has the function of collecting data indicating the activity level of, for example, cows C raised by a dairy farmer, analyzing the data, and adjusting the amount of data to be acquired. The animals from which data is collected are not limited to cows C, but may include all animals that are beneficial to identify and utilize the activity level of, such as pigs, sheep, horses, goats, and other animals that fall into the category of so-called farm animals, animals kept in zoos, so-called pets, and humans. Figure 1 is a schematic plan view showing three cattle pens (CB1-CB3) located within the barn. While Figure 1 shows 10 cows (C) being kept in one pen, the number of cows (C) in each pen is not particularly limited. For example, it could be less than 10 or 10 or more. Within each cattle pen (CB), feeding areas, nursing areas, and watering areas are provided in appropriate locations, allowing the cows (C) to eat (feeding), drink milk (sucking), and drink water (drinking) in their respective areas. The data acquisition system S comprises multiple sensor devices 2 (sensors) and a data acquisition device 1. As shown in Figure 1, all cows C in each barn CB are equipped with sensor devices 2 that include position sensors, and position information indicating the location of the cow C is acquired. The sensor devices 2 are provided with a data transmission function, and the acquired position information is transmitted to the data acquisition device 1, for example, by near-field communication (NFC). In this embodiment, the sensor devices 2 are fixed to tabs attached to the ears of the cows C, but they may also be fixed to collars and worn around the necks of the cows C, or configured to be attached to other parts of the body. The data collection device 1 is an information processing device that implements the main functions of the data collection process in this embodiment, located near the cowshed, including the cow pen CB, for example, in the dairy farm's management building. The data collection device 1 acquires and analyzes data indicating the activity level of each cow C, such as location information, from sensor devices 2 attached to each cow C, and performs processing to adjust the amount of data acquired based on the analysis results. <Sensor device 2> Next, the functional configuration of the sensor device 2 will be described. Figure 2 is a block diagram illustrating the hardware and functional block configuration of the sensor device 2. As shown in Figure 2, the sensor device 2 comprises a processing unit 21, a position information detection unit (data detection unit) 22, a power supply unit 23, and a communication unit 24. The location information detection unit 22 is a sensor for acquiring location information, which is data indicating the acti
