2. Problem Analysis of Conventional Pet Care

Due to the demand for efficient management of dogs at home, interest in management systems for dogs has been amplified. However, pet management systems are limited to areas such as automatic temperature control or automatic food feeders in tropical fish aquariums.

Recently, there has been a study of reactions and behaviors between humans and animals (9, 10). These studies focus on the analysis of the dog's behavior based on physical cues such as behavior, Utterance and heart rate counts. The results of these studies could be applied to dog management systems.

The main problem with a dog management system is in voice generation, food supply or the treatment of urine / feces, such as in apartments. The requirements of a dog management system using a wireless sensor network are affected by various environmental factors such as temperature and living patterns. Therefore, the present invention considers a form of residence such as an apartment.

The first problem is the noise produced by dogs. Dogs build to protect their range of power against people or things they are not instinctively familiar with. However, this is a cause of discord between apartment residents and dog owners.

Figure 4 is a table comparing the voice frequency range and the audible frequency range of the person and dog used in the present invention. In Figure 4 the audible frequency range of the dog is four times wider than the human audible frequency range.

Figure 5 is a table showing the frequency according to the situation of the dog used in the present invention.

So, when the dog feels lonely, the gate frequency of the dog's barking is 90 ~ 100Hz or 450 ~ 600Hz, when it feels threatening, it shows 700 ~ 900Hz, when it feels fun, it shows 950 ~ 1050Hz It shows 550 ~ 700Hz. This frequency analysis of dog barking has recently been studied, suggesting a common pattern for emotion in many types of dogs [9].

Figure 6 is a view showing the glottal frequency density of the pet dog used in the present invention, Figure 7 is a graph showing the glottal frequency graph of the pet dog used in the present invention, the barking sound when the dog is frustrated and threatened by a frequency analyzer to be.

The frequency analysis of the dog's barking can be used to analyze the dog's needs and health status. As shown in FIG. 7, it can be seen that the glottal frequency has a different frequency distribution depending on the dog emotion.

If you manage a dog, you can determine the dog's needs and emotional state by comparing the waveforms for each bark. It can be used as a device to manage several dogs.

8 is a view showing an example of the waveform of the glottal frequency of the dog used in the present invention.

9 is a flow chart showing an example of the waveform pattern analysis of pet dogs in the present invention. 9 shows an example of analyzing a pet dog gate frequency generated as shown in FIG. 8.

A wireless management system using a wireless sensor network consists of a multi-node connection. This wireless management system can therefore be extended to multifunctional applications for managing dogs.

The second problem is that the timer-based automatic feeder can be operated unnecessarily even without a dog. Therefore, a timer-based automatic feeder would have to go through additional set-up procedures manually for proper operation when people and pets are outside the home. If the feeder can automatically detect that the dog is at home, it will be able to feed the dog more effectively.

A third problem is the environmental changes caused by the urine / feces excreted by dogs. This is due to temperature change. These feces can be detected by the temperature sensor 120 mounted on the neck of the dog. The temperature data measured from the sensor may be used to control the temperature control unit 430 composed of a fan or a heater. In addition, the temperature sensor 120 may be applied to monitor the health status of the dog by sensing the temperature of the dog body.

In addition, by operating the pet dog induction mini-robot 410 so as to attract the attention of the dog can be used to reduce the unnecessary noise generated by the food supply is automatically operated at night.

In consideration of these problems, the present invention implements a pet dog management system.

3. Structure of Dog Management System

The present invention uses basic blocks for a ubiquitous computing environment.

3-1. Configuration and operation of pet dog sensor

The pet dog sensor unit 100 includes a light sensor 110, a temperature sensor 120, an acoustic sensor 130, and an electronic and acceleration sensor. The wireless sensor network may also include a microphone-based sound system that can be used to measure the dog's glottal frequency range. Wireless sensor networks also apply the standard ([11]. [12]) IEEE 802.15.4 communication protocol for low-speed local area network (PAN).

The main manager 200 may collect sensor information from each wireless sensor node of the pet dog sensor unit 100, and transmit the collected information to the controller 310 of the wireless controller 300. The control command from the wireless control unit 300 is transmitted to each device. Each control operation such as mini-robot control 410, food supply 420 control, and temperature control unit 430 control by sensor information such as light, temperature, and sound is used to attract attention of the dog using mixed sensing information. It can be used to.

10 is a table showing a control target using the data sensed in the present invention.

So, if the item managed by the dog sensor unit 100 is the light by the light sensor 110, the control target may be an automatic food supply by the food supply unit 420. In addition, an electric fan or heater (heater) control using the temperature controller 430 may be performed by temperature management through the temperature sensor 120. In addition, by controlling the sound by the acoustic sensor 130, the mini-robot 410 which is a small induction robot can be controlled to attract the dog's attention. In addition, in the case of the complex detection through the pet dog sensor 100, it is possible to perform a health check or security check of the dog.

Thus, when the dog detects the barking sound through the acoustic sensor 130, the mini robot 410 or another device can be operated. When the pet dog approaches the food supply unit 420 that operates wirelessly, the light sensor 110 of the pet dog sensor unit 100 checks the light sensitivity and the food supply unit 420 automatically operates. When the room temperature changes, the temperature sensor 120 detects this and delivers it to the main manager 200, and the main manager 200 controls the temperature controller 430 through the wireless controller 300 to control the temperature of the fan or heater. Temperature control through the control unit 430 may be executed.

In addition, in FIG. 1, the main manager 200 may be connected to a PDA or a mobile phone (not shown). Thus, the PDA or mobile phone receives the measured data wirelessly through each sensor node of the pet dog sensor 100.

All these components are controlled via wired or wireless links.

While the wireless sensor network is operating, the sensed data such as light, temperature, and sound are transmitted to the main manager 200 and the wireless controller 300. In addition, the communication between the mini robot 410 constituting the actuator, the food supply unit 420, the temperature control unit 430, and the wireless control unit 300 may be performed through RF communication having a frequency of 433 Hz bandwidth.

Include. In addition, a timer and a light emitting diode (LED) may be supported for operation of each module.

12 is a detailed block diagram illustrating reception data management in a data processing unit according to the present invention.

The data processor 220 may be configured as an I / O (input / output, input / output) process, a library, and an RfmToIntM module. RfmToIntM converts the received I / O data into integer (Integer, Int) type. The data processing unit 220 that is RfmToInt receives data from the receiving module and transmits the data to the controller 300 of the wireless controller 300. The controller 310 of the wireless control unit 300 transmits a control command to each of the wireless devices, such as the mini robot 410, the food supply unit 420, the temperature control unit 430, and the like.

3-2-2. Packet Structure of Main Administration

The transmission protocol of the wireless sensor network consists of 36 bytes.
