Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is a control block diagram of a Bluetooth camera device 10 and a security camera system 1 including the same according to a first embodiment of the present invention. As shown in FIG. 1, the security camera system 1 according to the first embodiment of the present invention includes a Bluetooth camera device 10 and a network communication module 20.

The Bluetooth camera apparatus 10 determines whether an intruder is present and transmits the image data and the audio data photographing the intruder to the network communication module 20 through Bluetooth communication, and the network communication module 20 transmits the image data and the audio. The data is transmitted to the predetermined user terminal 40 through the network communication network 30.

Accordingly, the user can know the external intrusion through the user terminal 40 and can take a prompt action accordingly.

For example, when the user knows an external intrusion fact, the user may transmit a warning voice to the network communication module 20 in real time through the user terminal 40, and the network communication module 20 may transmit the warning voice of the user to the Bluetooth camera device ( 10) can be output in real time through the speaker (15). Of course, you can report to the police or fire departments to effectively secure your facility without having a private security company.

As shown in FIG. 1, the Bluetooth camera device 10 according to the first embodiment of the present invention includes a CCD camera 11, an infrared sensor 12, a microphone 13, a Bluetooth communication module 14, and a speaker ( 15) and a control unit 16.

The CCD camera 11 is for capturing an image, and converts the image into an electrical signal using a CCD element, and a fixed camera or a mobile camera may be used. In particular, the CCD camera 11 may be equipped with an infrared LED to enable imaging even in the daytime as well as night light is dark.

The infrared sensor 12 detects a movement of an object using infrared rays, and is an active sensor that detects a signal by applying energy modified by the transmission, absorption, and reflection of energy applied to the object. Both passive and passive sensors that take energy from the object can be applied. Preferably, the use of an active sensor is more advantageous for identifying the movement of the object.

The microphone 13 is for converting an ambient signal into an electrical signal, and the Bluetooth camera device 10 includes an A / D converter (not shown) for converting an analog signal input to the microphone 13 into digital data. It may further include. As described above, according to the present invention, by adding the microphone 13, it is possible to verify whether an intruder is more accurate than the conventional method through not only the image data from the CCD camera 11 but also the audio data from the microphone 13.

The Bluetooth communication module 14 is for Bluetooth communication with the network communication module 20. Generally, a module capable of communicating with a distance of about 10m to 12m with an output of 10mw may be used, but in some cases, a frequency hopping method may be used. You can also use modules that can communicate from 100m to 1000m with a 2MHz 100mw output.

The speaker 15 is for outputting voice data, so that the warning voice of the user transmitted through the network communication module 20 can be output in real time. As a result, the intruder can be alerted.

The controller 16 is responsible for the overall control of the Bluetooth camera device 10, and may be implemented as a central processing unit (CPU), a microcomputer, or the like. The controller 16 operates the CCD camera 11 and the microphone 13 when the movement of the object is detected from the infrared sensor 12. That is, the CCD camera 11 and the microphone 13 do not operate normally, and the operation is activated according to the control signal of the controller 16 only when the movement of the object is captured from the infrared sensor 12.

At this time, the controller 16 analyzes the image data and audio data input from the activated CCD camera 11 and the microphone 13 to verify the presence of an intruder. The presence or absence of an intruder is verified by using various algorithms based on at least one of the motion vector of the object, the size of the object from which the motion is detected, the luminance difference between the object and the surroundings, and the amount of change of the audio data.

For example, when the motion is detected through the infrared sensor 12, by analyzing the image data input from the camera, if the size of the motion vector is larger than a predetermined reference value, it may be determined that there is an intruder. In addition, when the size of the object from which the motion is detected is larger than a predetermined reference value, or when the luminance difference between the object and the surrounding motion is larger than the predetermined reference value, it may be determined that there is an intruder.

On the other hand, even when the amount of change in the audio data is larger than the predetermined reference value, it can be determined that there is an intruder. For example, when the lighting is dark at night or when the intruder's visual identification is not easy, the audio data may contribute to the determination of the intrusion.

In addition to the image data and the audio data, the sensor detection amount from the infrared sensor 12 may also be a reference for determining whether an invasion occurs. The higher the detection amount of the sensor, the higher the probability of intrusion. As described above, one or more of the basic variables in the verification of the intrusion may be considered, and if the data to be derived from a plurality of variables are derived, it means that the probability of intrusion is further increased. In addition, each of these variables may be weighted.

Algorithm techniques used to verify the intrusions described above include, as is well known in the art, probabilistic Bayesian technique, Kalman technique, artificial intelligence fuzzy theory, neural network theory, expert theory, chaos theory, genetic algorithm And the like can be used. The controller 16 can be used to verify the likelihood of intrusion by assigning the aforementioned variables to the functions used in these techniques.

As described above, since the presence of an intruder is conventionally determined using only the infrared sensor 12, the reliability of the determination becomes a problem. However, the present invention analyzes the image data and audio data from the camera and the microphone 13 to determine whether the intruder exists. Because we verify, we can have higher confidence in the judgment.

If it is determined that there is an intruder through the above-described verification process, the controller 16 transmits the image data from the CCD camera 11 and the audio data from the microphone 13 through the Bluetooth communication module 14 to the network communication module ( 20). In this case, the controller 16 may include a codec processing module for digitally processing image data and audio data and decoding warning voice data transmitted from a network module.

The image data and audio data transmitted to the network communication module 20 are processed in accordance with a predetermined network transmission protocol and transmitted to the external user terminal 40 that is previously designated through the network communication network 30.

Meanwhile, the Bluetooth camera device 10 may further include a data storage unit (not shown), and the controller 16 transmits the image data and the audio data through the network communication module 20 and simultaneously stores them in the data storage unit. You can. Alternatively, the network communication module 20 may include a data storage unit, and transmit the image data and audio data transmitted from the Bluetooth camera device 10 through the network communication network 30 and simultaneously store the data data in the data storage unit. It may be. The data storage unit may be implemented as a hard disk, CD, or other memory device.

The network communication module 20 may include a modem, and the network communication network 30 includes a public telephone network (ISTN) 31, a wired / wireless repeater, an internet network 35, and a mobile communication network 36. The terminal can be connected to the mobile communication terminal 40A or the user's computer terminal 40B. In addition, the network communication network 30 has various forms of access for transmitting and relaying image data and audio data transmitted through the network communication module 20 to the user's mobile communication terminal 40A or the user's computer terminal 40B. It can include a server. DB server 32 Web server 33, WAP server 34 and the like can be used to store the transmitted data by date, time, and transmit the data to a predetermined user terminal. A detailed schematic diagram thereof will be described with reference to FIG. 2.

As described above, the user can transmit a warning voice through the user terminal 40, the access server transmits the warning voice data to the network communication module 20 so that the warning voice is a speaker ( 15) to enable real-time output. As such, according to the present invention, the intruder can be warned of danger.

Meanwhile, the Bluetooth camera device 10 according to the first embodiment of the present invention may further include a gas leak sensor 17 and / or a fire detection sensor 18.

The controller 16 operates the CCD camera 11 and the microphone 13 when a detection signal is input from the gas leak sensor 17 and / or the fire detection sensor 18. Then, the data from the gas leak sensor 17 and / or the fire detection sensor 18, the CCD camera 11, and the microphone 13 is analyzed, and the above-described algorithm is similarly applied to the sensor data change amount and the temperature change amount. In addition, at least one of brightness change is considered to determine whether a gas leak or a fire occurs. When the sensor data change amount, the temperature change amount and / or the luminance change amount with the surroundings are larger than predetermined reference values, it may be determined that a gas leak and / or a fire has occurred.

If it is determined that a gas leak and / or a fire has occurred, the controller 16 transmits the image data from the CCD camera 11 and the audio data from the microphone 13 to the Bluetooth communication module 14 similarly to the case of the intruder described above. And transmits to the network communication module 20. Accordingly, the network communication module 20 transmits the data to the predetermined user terminal 40 through the network communication network 30 to inform the user of the fact. Accordingly, the user can check the current situation and promptly contact the gas safety construction or fire department to take immediate action.

As such, the present invention further includes a gas leak sensor 17 and / or a fire detection sensor 18 in addition to the infrared sensor 12 to cope with various emergency situations.
