Description

Wireless Solar CCTV

The present invention relates to a wireless solar CCTV, and more particularly, to a CCTV that can be used wirelessly using a solar panel and can be driven with low power.

In general, a video surveillance (CCTV) device is a device that acquires surveillance images through a camera in order to monitor or control a specific area. CCTV devices are mainly installed inside parking lots, facilities, buildings, etc., and electrical wiring is essential to receive power required for operation.

When supplying power to such a CCTV device, a terminal box is provided separately around the CCTV device is installed, and the power supplied by the box is converted into usable power for the CCTV device to distribute power. However, since the CCTV device must be installed by drawing commercial power during electrical wiring, it is possible to install and use it only through a security service company or a specialized CCTV company due to complicated wiring methods and difficulties in installation.

In order to solve the inconvenience caused by such electrical wiring, there has been a need for the development of CCTVs that operate wirelessly. In particular, there has been a continuous need for CCTVs that can operate wirelessly for a long time to install CCTVs necessary for crime prevention or forest fire monitoring in places where commercial power is difficult to draw, such as remote areas or mountainous areas.

3 is a structural diagram of a wireless solar CCTV according to another embodiment of the present invention.

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

Referring to FIG. 1, the wireless solar CCTV 100 according to the present embodiment includes a housing 110, a camera module 120, a solar charging module 130, a battery 140, a power supply unit 150, and an encoder. 125, a memory unit 129, a PIR sensor 160, a first antenna 171, a second antenna 172, a wireless communication module 173, and a microcontroller 180.

The housing 110 may configure the exterior of the wireless solar CCTV according to the present embodiment. Other components may be placed inside or connected to the outside of the housing.

The camera module 120 may capture images and convert them into electrical signals. The camera module may include a CCD or CMOS image sensor. Since the wireless solar CCTV according to the present embodiment must operate by solar charging without external power supply, it is preferable to include a CMOS image sensor with relatively low power consumption. The camera module 120 may include a visible ray image sensor for capturing a visible ray image and an infrared image sensor for capturing an infrared image. During the daytime, since the amount of light is sufficient, a clear image can be obtained from the visible light image sensor, but at night or in rainy weather, an image captured in the visible light region may not be clear. In preparation for this case, an infrared image can be captured by using an infrared image sensor.

The solar charging module 130 may be a solar cell manufactured for the purpose of converting solar energy into electrical energy. The solar panel uses photovoltaic power generated by a photoelectric effect when light is irradiated on a contact surface between a metal and a semiconductor or a PN junction of a semiconductor. There is a selenium photovoltaic cell and a copper sulfite photovoltaic cell using the contact between a metal and a semiconductor, and a silicon photovoltaic cell used as a solar cell using a semiconductor PN junction. A solar cell has a structure in which an N (negative) type semiconductor and a P (positive) type semiconductor are bonded together, and the boundary between the two semiconductors is called a PN-junction. When light hits, sunlight is absorbed into the solar cell, and particles with electricity of holes and electrons are generated in the semiconductor by the energy of the absorbed solar light, respectively, and move freely into the solar cell. Although it moves, electrons gather toward the N-type semiconductor and holes gather toward the P-type semiconductor, and a potential is generated, which causes current to flow.

The battery 140 may store electricity generated by the solar charging module 130 . The type of battery may be implemented in various ways. The battery is formed to be inserted into a partial area of the housing, and a separate cover is formed so that the battery can be easily replaced. Although not separately shown, a separate charging terminal for charging the battery with commercial power may be additionally formed. When sufficient initial charging is not performed by the solar charging module 130, the battery may be charged by connecting a commercial power source or an external power source through a separate charging terminal. In this embodiment, the battery may have an output voltage of 3.7 to 4.2V.

The power supply unit 150 may serve to supply electricity stored in the battery to each part mounted on the housing. The power supply unit 150 may supply power to each part requiring electrical operation in the wireless solar CCTV according to the present embodiment. In this embodiment, it is possible to calculate the minimum current required for each unit requiring power and to transfer only the current required for each unit from the power supply unit 150 . By doing this, it is possible to minimize the operating current of the wireless solar CCTV according to the present embodiment.

The encoder 125 may be connected to the camera module 120 and compress image data photographed by the camera module in a predetermined format. In order to transmit image data captured by the camera module to an external device through wired or wireless communication, it is necessary to compress the image into a standardized format. In this embodiment, the encoder 125 may compress photographed image data into a format for wireless communication.

The memory unit 129 may store video data compressed by the encoder. The memory unit may include a temporary memory such as SDRAM for temporarily storing the compressed image data. Also, the memory unit may include a flash memory such as an SD card.

The PIR (Passive Infra-Red) sensor 160 is a sensor that is arranged to face a direction in which the camera captures and detects an operation in front of the camera. The PIR (Passive Infra-Red) sensor is also referred to as an infrared human body detection sensor. The PIR sensor means a passive infrared sensor and can detect the movement of a human body in a certain section at an acute angle of 9 to 12 degrees through a Fresnel lens. Due to the characteristics of the sensor, errors in the number of counts may occur due to masking effects, etc., but an algorithm that can reduce the range of errors in the long term with statistical techniques is adopted. Instead, it can be operated for a long time without an external power source with very low current consumption, and because it can be manufactured in a small size, it is easy to design waterproof and drip proof, and has the advantage of being able to operate for more than one year without special maintenance. In particular, when a mobile communication modem is installed, it has the advantage of being able to install and collect data anywhere in the country regardless of the installation location.

The first antenna 171 is attached to the housing and is an antenna for WiFi to communicate with external monitoring equipment. When a plurality of wireless solar CCTVs are installed, they can be formed into one network and monitored by one server terminal. At this time, a plurality of wireless solar CCTVs can be linked to a WiFi network NVR (Network Video Recorder) to simultaneously monitor and simultaneously store a plurality of wireless solar CCTVs. In addition, by connecting wireless solar CCTVs to a WiFi router or LTE Internet, multiple wireless solar CCTVs can be monitored on a server terminal or smartphone or tablet PC connected to the Internet through a gateway, and multiple wireless CCTVs can be simultaneously accessed and monitored. .

The second antenna 172 is attached to the housing and is an antenna for mobile communication for direct communication with an external smart phone.

The wireless communication module 173 may transmit and receive information through the first antenna and the second antenna. The wireless communication module may include a wireless communication module for WiFi and a wireless communication module for mobile communication. The wireless solar CCTV according to the present embodiment may include a wireless communication module for mobile communication such as LTE. At this time, the second antenna 172 can directly connect the CCTV and the user's smartphone using the wireless communication module 173 for mobile communication. The second antenna can enable direct wireless communication for mobile communication between the CCTV and the smart phone in this way. The wireless solar CCTV according to the present embodiment may further include a speaker and a microphone, and a call may be made between a manager's smartphone and a person near the CCTV through the speaker and microphone.

The microcontroller (MCU) 180 may control the operation of each part connected to the power supply unit. The circuit configuration can be designed so that each component installed in the wireless solar CCTV according to the present embodiment can operate with a minimum current. Therefore, the microcontroller can control the current supplied from the power supply unit to each unit so as to supply only the minimum current to each component of the wireless solar CCTV according to the present embodiment.

In addition, when motion is detected by the PIR sensor 160, the MCU 180 may operate the camera module 120 for a preset time to perform photographing and recording. When motion is not detected by the PIR sensor for a certain period of time, the MCU may switch the camera module to a sleep mode and minimize power consumption of other components. When motion is detected by the PIR sensor, photographing and recording may be performed by operating the camera module. Even at this time, the camera module can be controlled to operate only for a set time of several seconds.

The MCU 180 may control the overall operation of the wireless solar CCTV according to the present embodiment. For example, when motion is detected by the PIR sensor, an alarm signal may be transmitted to an external smart phone through the second antenna 172 . In addition, even if there is no motion detection in the PIR sensor, when a preset signal is received from an external smart phone, the MCU can perform photographing and recording of the camera or transmit photographic information to the external smart phone.

The wireless solar CCTV according to the present embodiment may further include a warning lighting unit 190 . The warning lighting unit 190 is disposed on the front portion of the housing, and when motion is detected by the PIR sensor, the warning lighting unit may be turned on in a predetermined pattern. As the warning lighting unit 190, an LED may be used. For example, when the wireless solar CCTV according to the present embodiment is installed in an area where illegal dumping of garbage is prohibited, the PIR sensor detects the movement and turns on the warning lighting unit 190 when someone appears to dump garbage without permission. You can suppress speculation. Such warning measures may use voice, but since civil complaints may occur due to voice warning in residential areas, the intended purpose can be achieved by such warning lighting.

Although not clearly shown in the drawing, an LED light for lighting may be added to the lower area of the housing. Separately from the warning lighting unit 190, a separate light may be added to improve shooting quality by illuminating the surroundings of the CCTV. The LED light can be operated only when motion is detected around the CCTV in conjunction with the PIR sensor.

Referring to FIG. 2, the wireless solar CCTV 200 according to the present embodiment includes a housing 210, a camera module 220, a solar charging module 230, a battery 240, a power supply unit 250, a PIR A sensor 260, a first antenna 271, a second antenna 272, a microcontroller 280, and a warning light 290 may be included.

The housing 210 may configure the exterior of the wireless solar CCTV according to the present embodiment. Other components may be placed inside or connected to the outside of the housing. The housing is formed long in one direction and may be formed in a polygonal column shape with a mounting space formed therein. A camera module 220 is disposed on the front surface of the housing, a solar charging module 230 is disposed on the upper surface, and a plurality of

antennas

271 and 272 may be installed on the rear surface. A battery 240, a power supply unit 250, a microcontroller 280, and the like may be disposed inside the housing. In addition, a PIR sensor 260 and a warning light 290 may be disposed on the front of the housing where the camera module is disposed.

Protruding covers may be formed on the top and both sides of the front portion of the housing. Since a camera module, a PIR sensor, a warning light, etc. are exposed to the outside on the front of the housing, it is necessary to protect these components from the external environment. Accordingly, the components may be protected by forming the top and both sides of the front portion of the housing to protrude beyond the front portion of the housing where the camera module, the PIR sensor, and the warning light are disposed.

The camera module 220 may capture images and convert them into electrical signals. The camera module may include a CCD or CMOS image sensor. Since the wireless solar CCTV according to the present embodiment must operate by solar charging without external power supply, it is preferable to include a CMOS image sensor with relatively low power consumption. The camera module 220 may include a visible ray image sensor for capturing a visible ray image and an infrared image sensor for capturing an infrared image. During the daytime, since the amount of light is sufficient, a clear image can be obtained from the visible light image sensor, but at night or in rainy weather, an image captured in the visible light region may not be clear. In preparation for this case, an infrared image can be captured by using an infrared image sensor. An image captured by the camera module 220 may be compressed through an encoder and stored in a memory.

The solar charging module 230 may be a solar cell manufactured for the purpose of converting solar energy into electrical energy. The solar panel uses photovoltaic power generated by a photoelectric effect when light is irradiated on a contact surface between a metal and a semiconductor or a PN junction of a semiconductor. There is a selenium photovoltaic cell and a copper sulfite photovoltaic cell using the contact between a metal and a semiconductor, and a silicon photovoltaic cell used as a solar cell using a semiconductor PN junction. A solar cell has a structure in which an N (negative) type semiconductor and a P (positive) type semiconductor are bonded together, and the boundary between the two semiconductors is called a PN-junction. When light hits, sunlight is absorbed into the solar cell, and particles with electricity of holes and electrons are generated in the semiconductor by the energy of the absorbed solar light, respectively, and move freely into the solar cell. Although it moves, electrons gather toward the N-type semiconductor and holes gather toward the P-type semiconductor, and a potential is generated, which causes current to flow. In this embodiment, the solar charging module 230 may be attached to the upper surface of the housing in a film type. The solar charging module may be additionally installed on the side of the housing. The position and shape at which the solar charging module is disposed may be variously designed according to the shape of the housing, the topography and position where the CCTV is installed, and the like.

The battery 240 is disposed inside the housing and can store electricity generated by the solar charging module 230 . The type of battery may be implemented in various ways. The battery is formed to be inserted into a partial area of the housing, and a separate cover is formed so that the battery can be easily replaced. Although not separately shown, a separate charging terminal for charging the battery with commercial power may be additionally formed. When sufficient initial charging is not performed by the solar charging module 230, the battery may be charged by connecting commercial power or external power through a separate charging terminal. In this embodiment, the battery may have an output voltage of 3.7 to 4.2V.

The power supply unit 250 is disposed inside the housing and may serve to supply electricity stored in the battery to each part mounted in the housing. The power supply unit 250 may supply power to each part requiring electrical operation in the wireless solar CCTV according to the present embodiment. In this embodiment, it is possible to calculate the minimum current required for each unit requiring power and to transfer only the current required for each unit from the power supply unit 250 . By doing this, it is possible to minimize the operating current of the wireless solar CCTV according to the present embodiment.

The PIR (Passive Infra-Red) sensor 260 is disposed on the front side of the housing to detect motion of the front side of the camera. The PIR sensor is also referred to as an infrared human body detection sensor. The PIR sensor means a passive infrared sensor and can detect the movement of a human body in a certain section at an acute angle of 9 to 12 degrees through a Fresnel lens. Due to the characteristics of the sensor, errors in the number of counts may occur due to masking effects, etc., but an algorithm that can reduce the range of errors in the long term with statistical techniques is adopted.

In particular, when a mobile communication modem is installed, it has the advantage of being able to install and collect data anywhere in the country regardless of the installation location.

The first antenna 271 is attached to the rear of the housing and is an antenna for WiFi to communicate with external monitoring equipment. When a plurality of wireless solar CCTVs are installed, they can be formed into one network and monitored by one server terminal. At this time, if a plurality of wireless solar CCTVs are formed in the same WiFi network, the plurality of CCTVs can be directly monitored by the server terminal. In addition, by using a router or a gateway, the plurality of CCTVs can be monitored even from a remote server.

The second antenna 272 is attached to the rear of the housing and is an antenna for mobile communication for direct communication with an external smart phone.

At this time, the second antenna 272 can directly connect the CCTV and the user's smartphone using the wireless communication module for mobile communication. The second antenna can enable direct wireless communication for mobile communication between the CCTV and the smart phone in this way. The wireless solar CCTV according to the present embodiment may further include a speaker and a microphone, and a call can be made between a manager's smartphone and a person near the CCTV through the speaker and the microphone.

The microcontroller (MCU) 280 may control the operation of each part connected to the power supply unit. The circuit configuration can be designed so that each component installed in the wireless solar CCTV according to the present embodiment can operate with a minimum current. Therefore, the microcontroller can control the current supplied from the power supply unit to each unit so as to supply only the minimum current to each component of the wireless solar CCTV according to the present embodiment.

In addition, when motion is detected by the PIR sensor 260, the MCU 280 may operate the camera module 220 for a preset time to perform photographing and recording. When motion is not detected by the PIR sensor for a certain period of time, the MCU may switch the camera module to a sleep mode and minimize power consumption of other components. When motion is detected by the PIR sensor, photographing and recording may be performed by operating the camera module. Even at this time, the camera module can be controlled to operate only for a set time of several seconds.

The MCU 280 may control the overall operation of the wireless solar CCTV according to the present embodiment.

In addition, even if there is no motion detection in the PIR sensor, when a predetermined signal is received from an external smartphone, the MCU can perform shooting and recording of the camera or transmit image information captured by the CCTV to the smartphone.

The warning lights 290 are disposed on the front of the housing 210, and when motion is detected by the PIR sensor, the warning lights 290 may be turned on in a predetermined pattern. As the warning light 290, an LED may be used. For example, when the wireless solar CCTV according to the present embodiment is installed in an area where illegal dumping of garbage is prohibited, the PIR sensor detects the movement and turns on the warning lamp 290 when someone appears to dump garbage without permission. You can suppress speculation. Such warning measures may use voice, but since civil complaints may occur due to voice warning in residential areas, the intended purpose can be achieved by such warning lighting.

Referring to FIG. 3, the wireless solar CCTV 300 according to the present embodiment includes a housing 310, a camera module 320, a solar charging module 330, a battery 340, a power supply unit 350, and a PIR. A sensor 360, a first antenna 371, a second antenna 372, a microcontroller 380, and a warning light 390 may be included. Since the wireless solar CCTV 300 according to this embodiment has a difference in the solar charging module 330 compared to the embodiment of FIG. 2, this part will be mainly described. Since characteristics of other components may be the same as those of the embodiment of FIG. 2 , detailed descriptions of configurations will be omitted and operation processes will be mainly described.

In this embodiment, the solar charging module 330 may be formed on an upper surface of the housing 310 . The solar charging module 330 may be a solar cell manufactured for the purpose of converting solar energy into electrical energy. In this embodiment, the solar charging module 330 may be attached to the upper surface of the housing in a panel type, and an angle between the solar charging module and the upper surface of the housing may be adjusted. In this embodiment, the joint structure connection portion 335 is formed on the lower surface of the solar charging module 330 and the upper surface of the housing 310 to position the solar charging module 330 at various angles. can In this way, by implementing such that the angle formed by the solar charging module 330 and the upper surface of the housing can be adjusted, the solar charging efficiency can be increased regardless of the installation direction of the wireless solar CCTV. That is, since the angle of the solar charging module 330 can be adjusted in a direction in which sunlight can be best received, the amount of charge charged by the solar charging module 330 can be maximized. The connection part 335 connecting the solar charging module 330 and the housing 310 may be implemented in various forms.

The wireless solar CCTV (300) according to the present embodiment can independently install and operate only the CCTV without wired work. When the wireless solar CCTV 300 is installed, the angle of the solar charging module 330 may be adjusted so that the solar charging module 330 can receive sunlight well during the day.

The wireless solar CCTV 300 installed in this way can receive sunlight through the solar charging module 330 and convert light energy into electrical energy. The electrical energy converted in this way may be charged in the battery 340 disposed in the housing. Before a separate operation signal is received from the outside or motion is detected by the PIR sensor, the microcontroller 380 may operate the wireless solar CCTV in a sleep mode. In the sleep mode, electricity consumption inside the CCTV is minimized, so that the CCTV can be operated only with the electricity charged by the solar charging module without applying a separate external power source.

When motion is detected by the PIR sensor 360, the microcontroller 380 may operate the camera module 320 to record for a predetermined period of time. At this time, the recording duration of the camera module 320 may be set to several seconds. Therefore, if there is no continuous motion, an image of several seconds is recorded according to one motion detection, and the camera module can be switched to the sleep mode again.

When motion is detected by the PIR sensor 360, the microcontroller 380 may turn on the warning light 390. When the warning light 390 is turned on, a person passing in front of the camera can recognize that recording by the camera is in progress, so that unauthorized dumping of garbage can be prevented. In addition, the warning light 390 can serve as a light, so that the image quality can be improved during recording of the camera module at night.

In addition, when motion is detected by the PIR sensor, the microcontroller 380 may transmit an alarm signal to an external server or user terminal (smart phone, etc.). Since the wireless solar CCTV according to the present embodiment includes a first antenna 371 for WiFi and a second antenna 372 for mobile communication, it can be directly communicated with an external server or user terminal through the first antenna and the second antenna. communication can be performed. When motion is detected by the PIR sensor, an alarm signal is sent to the server or user terminal, so that a manager or user can access the CCTV to monitor the corresponding camera image.

When a signal for accessing the CCTV is received from an external user terminal through the second antenna, an image captured by the wireless solar CCTV can be transmitted to the user terminal in real time. In addition, the video recorded and stored in the CCTV may be transmitted to the user terminal. In addition, even if there is no motion detection in the PIR sensor, when a signal for accessing the CCTV is received from an external user terminal, the microcontroller can operate the camera module and communication module to record and transmit images.

The wireless solar CCTV according to the present embodiment may include a microphone and a speaker. Therefore, a voice call may be possible between the external user terminal and the wireless solar CCTV using a mobile communication network. Since the user terminal side can make a voice call while watching the video captured by the CCTV, it is possible to easily grasp the situation in the area where the CCTV is installed and deliver appropriate measures.
