Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1, an industrial camera based on a radio frequency circuit includes an image sensor 1, a first radio frequency chip 2, a second radio frequency chip 3, and an image processor 4, where the image sensor 1 is installed in a lens of the industrial camera, the image sensor 1 is bidirectionally connected to the first radio frequency chip 2, the first radio frequency chip 2 may adopt a parallel-serial converter with a model of MAX96705, a parallel pixel signal of the image sensor 1 is transmitted to the first radio frequency chip 2, the first radio frequency chip 2 converts the parallel pixel signal into a high-frequency serial pixel signal, which may reach up to 1.6Gbps, and the first radio frequency chip 2 may also transmit a photographing trigger signal and a control signal I2C to the image sensor 1, so that the image sensor 1 performs a photographing operation.
The first radio frequency chip 2 is bidirectionally connected with the second radio frequency chip 3 through a coaxial cable 21, the coaxial cable 21 can adopt a radio frequency coaxial cable of HRCAY-50-9, two concentric conductors are arranged in the coaxial cable 21, the conductors and the shielding layer share the cable with the same axis, and the second radio frequency chip 3 can adopt a serial-parallel converter with the model of MAX 96706.
The second radio frequency chip 3 is bidirectionally connected with the image processor 4, the second radio frequency chip 3 converts the high-frequency serial signal into a parallel pixel signal which can be processed by the image processor 4, and then the parallel pixel signal is transmitted to the image processor 4, so that the image processor 4 processes the photo data. The image processor 4 may be a DSP processor, and the image processor 4 may transmit the photographing trigger signal and the control signal I2C to the second rf chip 3, so that the second rf chip 3 transfers the photographing trigger signal and the control signal through the coaxial cable 21.
The image processor 4 is electrically connected to an external power source 5, and the coaxial cable 21 is used for transmitting pixel signals and simultaneously providing power signals for the first rf chip 2 and the second rf chip 3. The coaxial cable 21 is therefore responsible for supplying power during the transmission of information. The output end of the image processor 4 is bidirectionally connected with an external photo output system through a cable, and the photo output system is positioned in an external computer.
In this industry camera, power supply, data transmission and set up camera parameter command transmission and all share a cable, trigger camera signal of shooing and I2C signal and can also pass through coaxial cable 21 through the two-way transmission of first radio frequency chip 2 and second radio frequency chip 3's conversion back, avoid industry camera interconnect's cable more like this to can further reduce the inner space of industry camera, thereby reduce the overall dimension of camera.
Because of adopting coaxial cable 21 transmission signal and power supply, can reduce the filter circuit volume of camera pcb circuit board by a wide margin. The connection stability of the internal circuit of the industrial camera is improved, the data transmission bandwidth can be improved, and the effective signal transmission distance is greatly increased. After the appearance volume of the industrial camera is reduced, the industrial camera can adapt to installation tasks under complex production conditions, and products needing to be photographed and scanned are better monitored.
