Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a remote video transmission apparatus provided in an embodiment of the present application includes:
the camera module is used for converting a target scene into video data;
the main control chip is electrically connected with the camera module through an MIPI interface or an SPI interface and is used for converting the video data into transmission signals;
the wireless protocol chip is electrically connected with the main control chip and is used for converting the transmission signal into a transmission signal;
and the antenna is electrically connected with the wireless protocol chip and used for radiating the transmitting signal.
It can be understood that, when implementing the remote video transmission technical solution, the target scene needs to be converted into video data first. When acquiring video data, the video data can be acquired through a camera module. The video data here may be 1080P digital video. After the camera module acquires the video data, the video data can be converted into a transmission signal through a preset data transmission mode. In a specific embodiment, the number of the camera modules may be multiple, and under the cooperation of the wireless protocol chip and the main control chip, 1-to-many long-distance transmission is realized. Here, the video data may be converted into a transmission model through the main control chip. The main control chip can realize communication with the camera module through an MIPI interface or an SPI interface. Serial data transfer MIPI is a Mobile Industry Processor Interface (Mobile Industry Processor Interface). The MIPI interface signal is a low-voltage differential signal, the generated interference is small, and the anti-interference capability is strong. SPI is an abbreviation for Serial Peripheral Interface (Serial Peripheral Interface), a high-speed full-duplex synchronous communication bus. In a specific implementation process, the main control chip can adopt various models. In this application, the main control chip may adopt FHXXXX series chips, and the specific types are as follows: FH8856, FH8852, FH8856V200, FH8853V200, etc. The wireless protocol chip adopts the most advanced OFDM signal modulation and demodulation technology, the modulation bandwidth can be selected according to the actual situation, and the optimal phase modulation mode can be selected according to the signal quality and the data size, so that the transmission distance of the video is greatly increased, and the power consumption and the operation cost are reduced. The remote monitoring video is remotely transmitted to the monitoring center by combining the main control chip and the wireless protocol chip adopting the OFDM signal modulation and demodulation technology, so that the transmission efficiency of the video data can be effectively improved, and the implementation cost is reduced.
Further, the camera module comprises an image sensor and a camera;
the image sensor is electrically connected with the camera;
the image sensor is electrically connected with the main control chip.
It should be noted that the image sensor is a key device for converting a target scene into video data. In a specific embodiment, the model of the image sensor herein may employ a GC2053. The power supply and the reference ground of the image sensor can be provided by the main control chip, and can also be realized by other general ways.
Specifically, the camera adopts a pinhole camera.
It can be understood that the pinhole camera occupies a small space, has low power consumption and wide application scenes. In a specific embodiment, the maximum visual angle of the pinhole camera here may be 93 °, the hardware diameter of the pinhole camera may be 14mm, and the space occupied by the pinhole camera may be 15mm. Obviously, the power consumption of the remote video transmission device can be effectively reduced by shooting the target scene through the pinhole camera.
Further, the image sensor is connected with the main control chip through a 30AWG wire.
It is noted that AWG (American wire gauge), which is a standard for distinguishing wire diameters, is referred to as Brown & sharp gauge. The number of holes through which the wire passes before the last diameter is formed is indicated by the number of values preceding the AWG (e.g., 24AWG, 26AWG, 30 AWG), and the larger the number of values, the higher the grade of hole through which the wire passes, the smaller the diameter of the wire. The application connects the image sensor and the main control chip through the 30AWG wire, and reduces the power consumption of the remote video transmission device from another angle.
Specifically, the image sensor is electrically connected with the main control chip through an MIPI interface or an SPI interface.
It can be understood that there may be a plurality of communication modes between the image sensor and the main control chip, and different communication modes correspond to different pin connection modes. Referring to fig. 2, when the image sensor is electrically connected to the main control chip through the MIPI interface, the image sensor is mainly connected to the main control chip through the synchronous signal pin CKP, the synchronous signal pin CKN, the data pin D0P, the data pin D0N, the data pin D1P, the data pin D1N, the data pin D2P, and the data pin D2N. It should be noted that the above pins are only a part of MIPI interface pins, and other pins may also be used according to actual needs. Referring to fig. 3, when the image sensor is electrically connected to the main control chip through the SPI interface, the image sensor is mainly connected to the main control chip through the clock line pin SCL, the data line pin SDA, the clock pin CLK, the reset pin RES, the 3.3V voltage pin 3V3, and the ground pin GND. The SPI interface can select a 4-wire bidirectional data transmission mode according to actual needs, and can also select a 4-wire unidirectional data transmission mode according to actual working needs. It should be noted that the above pins are only a part of the SPI interface pins, and other pins may also be used according to actual needs.
Further, the main control chip is electrically connected with the wireless protocol chip through an SDIO interface.
Note that SDIO represents a secure digital input output. Referring to fig. 4, when the main control chip and the wireless protocol chip are connected by using the SDIO interface, the connection between the main control chip and the wireless protocol chip can be realized through the data pin SD0, the data pin SD1, the data pin SD2, the data pin SD3, the adapter clock pin CLK, and the command pin CMD. It can be understood that, by using the SDIO interface, high-speed input and output of data can be realized with lower power consumption, and the working efficiency of the long-distance video transmission device is effectively improved.
Specifically, the main control chip is electrically connected to the wireless protocol chip through an ethernet interface.
It is understood that ethernet is a widely used communication means for local area networks. An ethernet interface is a port for a network data connection. The connection between the main control chip and the wireless protocol chip is realized through the Ethernet interface, the performance is stable, and the failure rate is low.
Further, the wireless protocol chip adopts an 802.11ah protocol chip.
It is noted that 802.11ah is a specific protocol for the IoT scenario in the 802.11 protocol suite. The 802.11ah protocol chip applies the most advanced OFDM signal modulation and demodulation technology, can select modulation bandwidth according to actual conditions, and can also select an optimal phase modulation mode according to signal quality and data size. In a specific embodiment, when there are a plurality of camera modules, an 802.11ah chip can be used to cooperate with other components to implement 1-to-many long-distance transmission. By adopting the 802.11ah protocol chip, the transmission distance of the video can be greatly increased with extremely low power consumption and low cost.
Specifically, the antenna is a pen holder antenna.
It should be noted that, the pen holder antenna has simple manufacturing process, stable technology and low power consumption. In a specific implementation process, the antenna can adopt a pen-holder antenna with a frequency band within a range of 700M-900M.
Further, the size of the carrier for carrying the image sensor, the main control chip and the wireless protocol chip is 20mm × 65mm.
It should be noted that the image sensor, the main control chip, and the wireless protocol chip are collectively disposed on the same carrier. In a specific implementation process, the image sensor, the main control chip and the wireless protocol chip are longitudinally arranged to form a rectangle with the width of 20mm and the length of 65mm. The image sensor, the main control chip and the wireless protocol chip occupy 20mm in width, and the image sensor, the main control chip and the wireless protocol chip occupy 65mm in length. The distance between the camera and the image sensor is 20mm. The diameter of the circular space occupied by the camera is 15mm. Obviously, by controlling the size of the carrier, the occupied space can be effectively saved, and the power consumption of the remote video transmission device can be reduced.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrases "comprising a," "8230," "8230," or "comprising" does not exclude the presence of other like elements in a process, method, article, or apparatus comprising the element.
