Description

Wireless solar CCTV{WIRELESS SOLAR CCTV}

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

In general, a video surveillance (hereinafter referred to as CCTV) device is a device that acquires surveillance images through cameras to monitor or control a specific area. CCTV devices are mainly installed inside parking lots, facilities, and buildings, and electrical wiring is essential to receive the power needed for operation.

When supplying power to such a CCTV device, a separate terminal box is provided around the CCTV device, and the power supplied by the box is converted into usable power for the CCTV device and distributed. However, CCTV devices must be installed by drawing a commercial power source during electrical wiring, so they can only be installed and used through security service companies or professional CCTV companies due to complicated wiring methods and difficulties in installation.

There has been a need to develop CCTV that operates wirelessly to solve the inconvenience caused by electrical wiring. In particular, there has been a continued need for CCTV that can operate wirelessly for a long time to install CCTV necessary for crime prevention or forest fire surveillance in places where it is difficult to draw commercial power, such as remote or mountainous areas.

Figure 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 attached drawings.

1 is a configuration diagram of a wireless solar CCTV according to an embodiment of the present invention.

Referring to FIG. 1, the wireless solar CCTV 100 according to this 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 may be included.

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

The camera module 120 can 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 this embodiment must operate by solar charging without an external power supply, it is desirable to include a CMOS image sensor with relatively low power consumption. The camera module 120 may include a visible light image sensor for capturing visible light images and an infrared image sensor for capturing infrared images. During the day, the amount of light is sufficient, so clear images can be obtained from the visible light image sensor, but at night or in rainy weather, images taken in the visible light region may not be clear. In preparation for such cases, an infrared image sensor can be used to capture infrared images.

The solar charging module 130 may be a solar cell manufactured for the purpose of converting solar energy into electrical energy. The solar panel utilizes the photovoltaic effect that occurs when light is irradiated to the contact surface of a metal and a semiconductor or a PN junction of a semiconductor. Those that use contact between metals and semiconductors include selenium photovoltaic cells and copper sulfite photovoltaic cells, and those that use semiconductor PN junctions include silicon photovoltaics, which are used as solar cells. A solar cell has a structure in which an N (negative) type semiconductor and a P (positive) type semiconductor with different electrical properties are joined together. The boundary between the two semiconductors is called a PN-junction, and the solar cell is connected to the solar cell. When light hits, solar light is absorbed into the solar cell, and the energy contained in the absorbed solar light generates electrical particles such as holes and electrons within the semiconductor, which can each freely enter the solar cell. Although they move, electrons are concentrated toward the N-type semiconductor and holes are concentrated toward the P-type semiconductor, generating a potential, which causes current to flow.

The battery 140 can store electricity generated by the solar charging module 130. The types of batteries may be implemented in various ways. The battery is formed to be inserted into a certain area of the housing, and a separate cover can be formed to facilitate battery replacement. Although not separately shown, a separate charging terminal may be additionally formed to charge the battery with commercial power. If sufficient initial charging is not achieved by the solar charging module 130, the battery can 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 4.2 V.

The power supply unit 150 may serve to supply electricity stored in the battery to each part mounted in the housing. The power supply unit 150 can supply power to each part that requires electrical operation in the wireless solar CCTV according to this embodiment. In this embodiment, the minimum current required for each part requiring power can be calculated and the power supply unit 150 can be controlled to deliver only the current required for each part. By doing this, the operating current of the wireless solar CCTV according to this embodiment can be minimized.

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

The memory unit 129 can store image data compressed by the encoder. The memory unit may include a temporary memory such as SDRAM that temporarily stores the compressed image data. Additionally, the memory unit may include flash memory such as an SD Card.

The PIR (Passive Infra-Red) sensor 160 is a sensor that is arranged to face the direction in which the camera is shooting and detects motion in front of the camera. The PIR (Passive Infra-Red) sensor is also called an infrared human body detection sensor. The PIR sensor refers to a passive infrared sensor and can detect human movement in a certain section at an acute angle of 9 to 12 degrees through a Fresnel lens. Due to the nature of the sensor, errors in the number of counts may occur due to masking effects, etc., but an algorithm is adopted that can reduce the range of errors in the long term using statistical techniques. Instead, it consumes very little current and can be operated for a long period of time without external power. Since it can be manufactured in a small size, it is easy to design for waterproofing and spinning, and has the advantage of being able to operate for more than a year without special maintenance. In particular, when equipped with a mobile communication modem, 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 a WiFi antenna for communicating with external monitoring equipment. If multiple wireless solar CCTVs are installed, they can be formed into one network and monitored from one server terminal. At this time, multiple wireless solar CCTVs can be linked to a WiFi network NVR (Network Video Recorder) to simultaneously monitor and store multiple wireless solar CCTVs at the same time. In addition, by connecting the wireless solar CCTV to a WiFi router or LTE Internet, you can monitor multiple wireless solar CCTVs from a server terminal, smartphone, or tablet PC connected to the Internet through a gateway. Multiple users can also connect and monitor at the same time. .

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

The wireless communication module 173 can 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 this 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 smartphone. The wireless solar CCTV according to this embodiment may further include a speaker and a microphone, and a call may be made between the manager's smartphone and a person near the CCTV through these speakers and microphone.

The microcontroller (MCU, 180) can control the operation of each part connected to the power supply unit. Each component installed in the wireless solar CCTV according to this embodiment can be designed in a circuit configuration so that it can operate with minimal current. Accordingly, 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 this embodiment.

In addition, when movement is detected by the PIR sensor 160, the MCU 180 can operate the camera module 120 for a preset time to proceed with shooting and recording. If no movement is detected by the PIR sensor for a certain period of time, the MCU can switch the camera module to sleep mode and minimize power consumption of other components. When movement is detected by the PIR sensor, the camera module can be activated to proceed with shooting and recording. Even in this case, the camera module can be controlled to operate only for a set time of several seconds.

The MCU 180 can control the overall operation of the wireless solar CCTV according to this embodiment. For example, when movement is detected by the PIR sensor, an alarm signal can be transmitted to an external smartphone 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 smartphone, the MCU can proceed with shooting and recording of the camera or transmit shooting information to the external smartphone.

The wireless solar CCTV according to this embodiment may further include a warning lighting unit 190. The warning lighting unit 190 is disposed on the front part of the housing, and when movement is detected by the PIR sensor, the warning lighting unit 190 may light up in a preset pattern. The warning lighting unit 190 may use LED. For example, when the wireless solar CCTV according to this embodiment is installed in an area where illegal dumping of trash is prohibited, when someone shows up to dump trash without permission, the PIR sensor detects the movement and turns on the warning light unit 190 to prevent unauthorized dumping of trash. Speculation can be suppressed. These warning measures may use voice, but since voice warnings may cause civil complaints in residential areas, the intended purpose can be achieved with these warning lights.

Although not clearly shown in the drawing, LED lighting may be added for illumination in the lower area of the housing. Apart from the warning lighting unit 190, additional lighting may be added to improve shooting quality by illuminating the area around the CCTV. The LED lighting can be linked to a PIR sensor to operate only when motion is detected around the CCTV.

Figure 2 is a structural diagram of a wireless solar CCTV according to another embodiment of the present invention.

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

The housing 210 may configure the external appearance of the wireless solar CCTV according to this embodiment. Other components may be placed inside the housing or connected to the outside. The housing is formed to be long in one direction and may be formed in the form of a polygonal pillar with a mounting space formed therein. A camera module 220 may be placed on the front of the housing, a solar charging module 230 may be placed on the top, and a plurality of antennas 271 and 272 may be installed on the back. A battery 240, a power supply unit 250, a microcontroller 280, etc. may be placed inside the housing. Additionally, a PIR sensor 260 and a warning light 290 may be placed on the front of the housing where the camera module is placed.

A protruding cover may be formed on the top and both sides of the front part of the housing. Since the camera module, PIR sensor, warning light, etc. are disposed on the front part of the housing to be exposed to the outside, it is necessary to protect these components from the external environment. Accordingly, the components can be protected by forming the upper part and both sides of the front part of the housing to protrude beyond the front part of the housing where the camera module, PIR sensor, and warning lights are arranged.

The camera module 220 can 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 this embodiment must operate by solar charging without an external power supply, it is desirable to include a CMOS image sensor with relatively low power consumption. The camera module 220 may include a visible light image sensor for capturing visible light images and an infrared image sensor for capturing infrared images. During the day, the amount of light is sufficient, so clear images can be obtained from the visible light image sensor, but at night or in rainy weather, images taken in the visible light region may not be clear. In preparation for such cases, an infrared image sensor can be used to capture infrared images. The image captured by the camera module 220 may be compressed through an encoder and stored in 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 utilizes the photovoltaic effect that occurs when light is irradiated to the contact surface of a metal and a semiconductor or a PN junction of a semiconductor. Those that use contact between metals and semiconductors include selenium photovoltaic cells and copper sulfite photovoltaic cells, and those that use semiconductor PN junctions include silicon photovoltaics, which are used as solar cells. A solar cell has a structure in which an N (negative) type semiconductor and a P (positive) type semiconductor with different electrical properties are joined together. The boundary between the two semiconductors is called a PN-junction, and the solar cell is connected to the solar cell. When light hits, solar light is absorbed into the solar cell, and the energy contained in the absorbed solar light generates electrical particles such as holes and electrons within the semiconductor, which can each freely enter the solar cell. Although they move, electrons are concentrated towards the N-type semiconductor and holes are concentrated towards the P-type semiconductor, generating a potential, which causes current to flow. In this embodiment, the solar charging module 230 may be a film type and attached to the upper surface of the housing. The solar charging module may be additionally installed on the side of the housing. The position and form where the solar charging module is placed can be designed in various ways depending on the shape of the housing, the terrain and location where CCTV is installed, etc.

The battery 240 is disposed inside the housing and can store electricity generated by the solar charging module 230. The types of batteries may be implemented in various ways. The battery is formed to be inserted into a certain area of the housing, and a separate cover can be formed to facilitate battery replacement. Although not separately shown, a separate charging terminal may be additionally formed to charge the battery with commercial power. If sufficient initial charging is not achieved by the solar charging module 230, the battery can 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 250 is disposed inside the housing and may serve to supply electricity stored in the battery to each part mounted on the housing. The power supply unit 250 can supply power to each part that requires electrical operation in the wireless solar CCTV according to this embodiment. In this embodiment, the minimum current required for each part requiring power can be calculated and the power supply unit 250 can be controlled to deliver only the current required for each part. By doing this, the operating current of the wireless solar CCTV according to this embodiment can be minimized.

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

In particular, when equipped with a mobile communication modem, 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 a WiFi antenna for communicating with external monitoring equipment. If multiple wireless solar CCTVs are installed, they can be formed into one network and monitored from one server terminal. At this time, if multiple wireless solar CCTVs are formed on the same WiFi network, multiple CCTVs can be monitored directly from the server terminal. Additionally, using a router or gateway, the plurality of CCTVs can be monitored from a remote server.

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

The wireless solar CCTV according to this embodiment may include a wireless communication module for transmitting and receiving information through the first and second antennas. 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 this embodiment may include a wireless communication module for mobile communication such as 3G, 4G, LTE, and 5G. 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 smartphone. The wireless solar CCTV according to this embodiment may further include a speaker and a microphone, and a call can be made between the manager's smartphone and a person near the CCTV through these speakers and microphone.

The microcontroller (MCU, 280) can control the operation of each part connected to the power supply unit. Each component installed in the wireless solar CCTV according to this embodiment can be designed in a circuit configuration so that it can operate with minimal current. Accordingly, 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 this embodiment.

In addition, when movement is detected by the PIR sensor 260, the MCU 280 can operate the camera module 220 for a preset time to proceed with shooting and recording. If no movement is detected by the PIR sensor for a certain period of time, the MCU can switch the camera module to sleep mode and minimize power consumption of other components. When movement is detected by the PIR sensor, the camera module can be activated to proceed with shooting and recording. Even in this case, the camera module can be controlled to operate only for a set time of several seconds.

The MCU 280 can control the overall operation of the wireless solar CCTV according to this embodiment. For example, when movement is detected by the PIR sensor, an alarm signal can be transmitted to an external smartphone through the second antenna 272. In addition, even if there is no motion detection in the PIR sensor, when a preset signal is received from an external smartphone, the MCU can proceed with shooting and recording of the camera or transmit image information captured by the CCTV to the smartphone.

The warning light 290 is disposed on the front of the housing 210, and when movement is detected by the PIR sensor, the warning light 290 may turn on in a preset pattern. The warning light 290 may be an LED. For example, when the wireless solar CCTV according to this embodiment is installed in an area where illegal dumping of trash is prohibited, if someone shows up to dump trash without permission, the PIR sensor detects the movement and turns on the warning light 290 to prevent unauthorized dumping of trash. Speculation can be suppressed. These warning measures may use voice, but since voice warnings may cause civil complaints in residential areas, the intended purpose can be achieved with these warning lights.

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

Referring to FIG. 3, the wireless solar CCTV 300 according to this 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. It may include a sensor 360, a first antenna 371, a second antenna 372, a microcontroller 380, and a warning light 390. 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, the description will focus on this part. Since the characteristics of other components may be the same as the embodiment of FIG. 2, description of specific configurations will be omitted and description will be focused on the operating process.

In this embodiment, the solar charging module 330 may be formed on the 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 is a panel type and can be attached to the upper surface of the housing, and the angle formed between the solar charging module and the upper surface of the housing can be adjusted. In this embodiment, an articulated 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. You can. By implementing the solar charging module 330 so that the angle formed with the upper surface of the housing can be adjusted, 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 that best receives sunlight, the amount of charge charged by the solar charging module 330 can be maximized. The connection portion 335 connecting the solar charging module 330 and the housing 310 may be implemented in various forms.

The wireless solar CCTV 300 according to this embodiment can independently install and operate the CCTV without any wire work. When installing the wireless solar CCTV 300, the angle of the solar charging module 330 can be adjusted so that the solar charging module 330 can receive sunlight well throughout 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 can be charged to the battery 340 disposed within the housing. The microcontroller 380 may operate the wireless solar CCTV in sleep mode before a separate operation signal is received from the outside or movement is detected by the PIR sensor. In sleep mode, the electricity consumption inside the CCTV is minimized, allowing the CCTV to operate only with electricity charged by the solar charging module without applying a separate external power source.

When movement is detected by the PIR sensor 360, the microcontroller 380 operates the camera module 320 to record for a certain 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 movement, a few seconds of video is recorded based on a single movement detection, and the camera module can be switched back to sleep mode.

When movement is detected by the PIR sensor 360, the microcontroller 380 can turn on the warning light 390. When the warning light 390 is turned on, people passing in front of the camera can recognize that recording by the camera is in progress, thereby preventing unauthorized trash dumping. Additionally, the warning light 390 can serve as a light, improving image quality when recording by a camera module at night.

Additionally, when movement is detected by the PIR sensor, the microcontroller 380 can transmit an alarm signal to an external server or user terminal (smart phone, etc.). Since the wireless solar CCTV according to this embodiment includes a first antenna 371 for WiFi and a second antenna 372 for mobile communication, it can be directly connected to an external server or user terminal through the first antenna and the second antenna. Communication can be performed. By sending an alarm signal to the server or user terminal when motion is detected by the PIR sensor, an administrator or user can access the CCTV to monitor the camera video.

When a signal for accessing the CCTV from an external user terminal is received through the second antenna, the image being captured by the wireless solar CCTV can be transmitted to the user terminal in real time. Additionally, the video recorded and stored in the CCTV can be transmitted to the user terminal. In addition, even if the PIR sensor does not detect motion, 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 video.

The wireless solar CCTV according to this 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 voice calls while watching the video captured by the CCTV, the situation in the area where the CCTV is installed can be easily identified and appropriate measures can be taken.

Although the present invention has been described above with reference to preferred embodiments and examples, those skilled in the art may modify the present invention in various ways without departing from the spirit and scope of the present invention as set forth in the following patent claims. and that it can be changed. For example, the shape of the housing, the control and operation method of the microcontroller, etc. can be implemented in various ways.
