However, embodiments of the present invention illustrated below may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below.

1 is a conceptual diagram of a home automation system using an infrared sensor and a network of the present invention.

The server system 100 includes an infrared sensor 101, a DAQ system, and a digital camera.

The infrared sensor 101 transmits a signal of the infrared sensor according to the presence / absence of the entrance object to the DAQ system 102 of the server system 100.

The DAQ system 102 generates a camera operation signal using a signal of an infrared sensor that can be monitored through a computer and a DAQ (signal converter).

DAQ stands for Data Acquisition. The purpose of a DAQ system is to measure physical phenomena such as light, temperature, pressure, or sound. In other words, the DAQ system is a system that receives signals from the real world, that is, analog signals, and converts them to digital, and analyzes the converted data according to user requirements.

The building blocks of a DAQ system consist of transducers, signals, signal conditioning, DAQ devices, driver levels, and application level software. These components can be used to bring the physical phenomena you want to measure into your computer.

The digital camera 103 captures a still image or a video of the object according to a signal input through the DAQ.

The manager 110 is a management servo system. For example, the management servo system can convert an image signal captured by the digital camera 103 into an extension that can be easily attached by e-mail, for example, a JPG file, and send it by a conventionally designated e-mail. The management servo system can output the captured video signal directly to the display means.

Preferably, the entire system can be managed and operated on a LabVIEW basis.

In order to carry out the present invention, it is possible to experimentally grasp the characteristics of the device, check whether the device can be controlled between the devices, and use the camera to visually check the visual surface of the device and the operation of each device. And then you can make that signal work and program it.

First, understand the characteristics of the device and understand the power supply and the applied voltage and current.

FIG. 2 shows an example of a relay circuit that allows sufficient voltage to be applied to the elements when implementing the present invention.

The output voltage using DAQ is 5V voltage, so the 12V relay (DY1S-12H) as shown in Fig. 2 is installed for sufficient effect of current transfer. Can be installed and confirmed so that voltage is applied.

Second, to check the visual side of each device and whether each device works by using the camera, you can write a program that binds the signal out through DAQ to the device and checks whether the device works normally. However, if the camera information is not entered, it will not be recognized. Therefore, when you install LabVIEW, the library file for the Web Cam must be saved, specified in the folder, and executed in order to receive the correct image from the camera. .

Third, by using a wired network, communication between a server and another PC, which is a client, can control the image sent from the server to the camera module through a switching operation at the client.

Therefore, when the server computer is connected to the DAQ and connected to the relays and circuits of each device, the server's IP is entered into the client search box using the web publishing tool in the LabVIEW program toolbar before the program is executed. Run-time settings in the window allow the client computer to control the server. In this case, the web publishing tool can be replaced with software that can implement similar operations in addition to the LabVIEW program.

You can manage devices in your home (door, window, temperature) using a client program via a monitor or wireless LAN. Therefore, by using a wireless network through other wired computers, laptops, PDAs, etc. with the server as the center, wireless network communication using the wired network communication up to now is also possible, and using a conventional wireless LAN device AP (Access Point) Can be connected and controlled

The connecting page of this home control scenario is managed through an important web-based interface that enables its control by a web interface.

With wired connections, you can use LabVIEW run-time modules to develop techniques and systems for controlling run times. It is also possible to take pictures through crash spots, monitor financial societies or prisons with a web server, and analyze the degree of crowding of complex places. For example, as shown in FIG. 1, it is possible to operate the fan, the motor, and the light in addition to the camera operation, which can be controlled using a communication network based on the web rather than just a manual operation. .

According to the present invention, to complement the above-mentioned disadvantages of CCTV and to implement the home automation network system of the concept of economical and efficient maximization to inform the administrator of the information and control it by using the web camera and infrared sensor in the building. Can be.

6 is a flowchart illustrating a method of implementing a home automation system using an infrared sensor and a network according to another embodiment of the present invention.

First, the entire system is maintained in the standby mode and the infrared sensor is operated (step 610).

Next, a signal (related to entry and exit) is captured through the infrared sensor (step 620).

In this case, when the signal of the infrared sensor is generated (step 620), it is sent to the DAQ system (step 630), or otherwise (step 620), the infrared sensor continues to operate (step 610).

Next, the infrared sensor signal is sent to the DAQ of the server to send the converted camera operation signal to the camera (step 630).

Next, the camera is operated according to the signal from the DAQ (step 640).

Finally, the captured photographing information, that is, the camera file is transmitted from the server to the administrator, and the manager or the management system checks the transferred file through the process of displaying the photographing information (step 650). At this time, the manager or the management system can release the lock of the access opening and closing means in real time as needed. At this time, when an unauthorized person tries to enter, the manager or the management system may keep the lock at the same time as the report.

Because LabVIEW is a graphical environment, you can use software objects to create what are called “virtual instruments” (VIs), in which VIs use the Internet for many VIs (VI Server, data socket server, visual). basic, active X, Java, and Java Script), and the easiest way to control and view VIs in a web browser, allowing you to run your application from anywhere on the Internet. As such, the utilization can be greatly improved.

A notable characteristic of VIs is the transparency of the network. This transparency allows you to process all instructions generated by VIs or LabVIEW itself on other machine systems over the network in the same way they are on your computer. Therefore, by creating a program as shown in Figure 6, the server and the client can be linked to send and receive data on the Internet. For example, when a web camera is activated through the detection of an infrared sensor when entering or exiting a door, the image information can be sent to a resident's e-mail to check who has been in and out of the door.

The invention can be implemented via software. When implemented in software, the constituent means of the present invention are code segments that perform the necessary work. The program or code segments may be stored in a processor readable medium or transmitted by a computer data signal coupled with a carrier in a transmission medium or communication network.

The computer-readable recording medium includes all kinds of recording devices in which data is stored which can be read by a computer system. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, DVD ± ROM, DVD-RAM, magnetic tape, floppy disks, hard disks, optical data storage devices, and the like. The computer readable recording medium can also be distributed over network coupled computer devices so that the computer readable code is stored and executed in a distributed fashion.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary and will be understood by those of ordinary skill in the art that various modifications and variations can be made therefrom. However, such modifications should be considered to be within the technical protection scope of the present invention. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, according to the present invention, when the web camera is activated through the detection of the infrared sensor when entering or exiting the door in the building or other structures that require this function, the image file is transferred to the Internet mail of the residents. The object can be identified, and at the same time, the manager can easily and efficiently check the control and the inside of the building. In addition, it is possible to interoperate with various programs that control various devices in a building with one wireless device, and can use a wireless LAN method well equipped with infrastructure in Korea. In particular, it is possible to implement a surveillance system that can perform simple functions by using a popularized USB web camera without a capture board. In addition, by using only 12Volt element voltage and server system in general house, it can reduce power consumption and reduce the cost of other additional equipment, and it can be configured relatively inexpensively than the conventional security system. It has an effect.
