[0025] Figure 1 It is a schematic structural diagram of an industrial camera based on a high-speed transmission channel provided by an embodiment of the present invention. As Figure 1 shown, the industrial camera includes: an image sensor 10, an image processor 20, an optical module 30, and a heat dissipation module 40 (not shown in the figure). The following will specifically describe the structural composition of the industrial camera in this embodiment.

[0026] The image sensor 10 is used to collect image data.

[0027] Specifically, the image sensor 10 is a photosensitive element that converts optical signals into electrical signals, and is used to convert the light (optical signal) passing through the camera lens into an electrical signal, and then generate a corresponding digital image, that is, image data.

[0028] In some embodiments, the image sensor 10 includes at least one of the following: a CCD image sensor, a CMOS image sensor.

[0029] Specifically, the image sensor 10 may employ a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor for high-speed acquisition of high-quality image signals. In this embodiment, no specific restrictions are imposed on the sensor parameters of the image sensor 10.

[0030] It should be understood that the number of image sensors 10 may be one or more, which can be specifically configured according to actual application requirements. This embodiment does not limit this.

[0031] The image processor 20 includes a sensor data receiving module 21, an image processing module 22, and a high-speed transmission channel 23. The sensor data receiving module 21 is connected to the image sensor 10 and is used to transmit the received image data to the image processing module 22. The high-speed transmission channel 23 is used to transmit the image data processed by the image processing module 22 to the optical module 30 through a high-speed serial interface.

[0032] Specifically, the image processor 20 may refer to the main control module of an industrial camera, which specifically includes a sensor data receiving module 21, an image processing module 22, and a high-speed transmission channel 23. Among them, the sensor data receiving module 21 is connected to the image sensor 10 through multiple channels and is used to receive the image data collected by the image sensor 10 at a high rate and transmit the image data to the image processing module 22 for subsequent processing. Since there is no direct connection between the image data received by the sensor data receiving module 21 and the subsequent high-speed transmission channel 23, the image processing module 22 is set to be responsible for reasonably segmenting and repackaging the image data and sending it to the high-speed transmission channel 23. The high-speed transmission channel 23 is used to transmit the image data processed by the image processing module 22 to the optical module 30 at a high frame rate and high resolution through the set high-speed serial interface, so as to realize lossless transmission of the image data to the image acquisition card outside the industrial camera.

[0033] In some embodiments, the image processor 20 includes a programmable gate array chip.

[0034] Specifically, the image processor 20 may use a Field-Programmable Gate Array (FPGA) chip as the main control chip of the industrial camera, and a very mature FPGA solution on the market can be adopted. That is, the type and parameters of the FPGA chip adopted in this embodiment are not specifically limited.

[0035] In some embodiments, the sensor data receiving module 21 is provided with at least 180 differential IO interfaces.

[0036] Specifically, in order to improve the efficiency of the sensor data receiving module 21 in receiving image data, a certain number of differential IO interfaces may be set in the sensor data receiving module 21. For example, Low-Voltage Differential Signaling (LVDS) IO interfaces can be used to connect to the image sensor 10, so as to receive image data with low power consumption, low bit error rate, low crosstalk, and low radiation. Among them, the number of differential IO interfaces set can be specifically configured according to actual needs. For example, it can include at least 180 differential IO interfaces.

[0037] In some embodiments, the high-speed serial interface includes at least: a high-speed SerDes interface.

[0038] Specifically, in order to transmit the image data processed by the image processing module 22 to the optical module 30 with high frame rate and high resolution, the high-speed serial interface set in the high-speed transmission channel 23 may include at least: a high-speed SerDes interface. Among them, SerDes (Serializer / Deserializer) is a high-speed time-division multiplexing, point-to-point serial communication technology, that is, at the sending end, multiple low-speed parallel signals are converted into high-speed serial signals, passed through the transmission medium (optical cable or copper wire), and finally at the receiving end, the high-speed serial signals are converted back into low-speed parallel signals. This point-to-point serial communication technology makes full use of the channel capacity of the transmission medium, reduces the number of required transmission channels and device pins, and improves the signal transmission speed, thus greatly reducing the communication cost. In this embodiment, the high-speed SerDes interface can support an interface rate of 40 Gbps and higher to ensure that the image data can be transmitted to the image acquisition card without loss, and at the same time support the function of retransmitting lost packets, ensuring the high reliability of data transmission.

[0039] The optical module 30 is connected to the image sensor 10 through the image processor 20 and is used to transmit the image data processed by the image processor 20 to the image acquisition card.

[0040] Specifically, in order to achieve high-speed and long-distance transmission of image data, an optical module 30 can be set in the industrial camera, so as to provide high frame rate, high resolution and high bandwidth support for data transmission between the industrial camera and the image acquisition card.

[0041] In some embodiments, the optical module 30 at least includes a 40G optical module.

[0042] Specifically, in order to enable the industrial camera to adapt to various application scenarios and meet richer application requirements, the optical module 30 can at least adopt a 40G optical module, that is, to ensure that the data transmission rate is at least 40 Gbps; at the same time, corresponding types of 40G optical modules can be adopted according to actual application requirements. For example, according to the distance of transmission, 40G optical modules with corresponding interface types and channel numbers can be selected. This embodiment does not make specific limitations on this.

[0043] In some embodiments, the 40G optical module is provided with a plurality of QSFP fiber optic interfaces.

[0044] Specifically, the 40G optical module can be provided with several QSFP (Quad Small Form-factor Pluggable) fiber optic interfaces for efficiently transmitting image data to one or more image acquisition cards, so as to realize the sharing of the same image data among multiple host computers and the simultaneous reception and access of image data by multiple host computers. Further, this embodiment does not make specific limitations on the number of QSFP fiber optic interfaces. For example, it can at least include 2.

[0045] In some embodiments, fiber optic connection is made with the image acquisition card through the QSFP fiber optic interface.

[0046] Specifically, through the set QSFP fiber optic interface, the industrial camera can be fiber-optically connected to one or more image acquisition cards, so as to realize efficient and long-distance transmission of image data between the camera and the image acquisition card.

[0047] The heat dissipation module 40 includes a heat dissipation fan embedded and installed on the top layer of the housing of the industrial camera.

[0048] Specifically, since the image processor 20 in the industrial camera consumes a large amount of power when processing high-speed image data, and at the same time the image sensor 10 and the optical module 30 also generate more heat during long-term operation, a heat dissipation module 40 is provided in the camera, specifically including a heat dissipation fan embedded and installed on the top layer of the camera housing, which is used to quickly export the hot air inside the camera to the outside of the camera, so as to realize rapid heat dissipation of the camera. Further, the heat dissipation module 40 can adopt a silent and high-performance fan to reduce equipment noise while achieving efficient heat dissipation.

[0049] In some embodiments, a T-shaped heat dissipation copper block is further installed under the cooling fan.

[0050] Specifically, in order to further improve the heat dissipation effect of the industrial camera, a heat dissipation copper block with a specific shape, such as a T shape, can be installed under the cooling fan to quickly dissipate the heat generated by the image sensor 10 and the image processor 20, thereby extending the service life of the camera and improving the reliability and quality of the camera.

[0051] In some embodiments, the industrial camera further includes a data storage module for caching the image data collected by the image sensor 10 and the corresponding algorithm program of the image processor 20.

[0052] Specifically, the industrial camera in this embodiment further includes a data storage module for caching the algorithm program corresponding to the image processor 20 and the image data collected by the image sensor 10 during the operation of the camera. Among them, the data storage module can be set outside the image processor 20 or other positions in the camera, and data memories such as non-volatile memory (NVM), double data rate synchronous dynamic random access memory (DDR) can be used, such as but not limited to Flash memory, DDR2 memory, DDR3 memory, and DDR4 memory, etc.
