The invention may be embodied in many other forms different from those described herein and similar modifications may be made by those skilled in the art without departing from the spirit and scope of the invention and, therefore, the invention is not to be limited to the specific embodiments disclosed below.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

As described in the background, imaging colorimeters have emerged to capture images on a display screen due to advances in flat panel display and like technologies. The imaging colorimeter is mainly applied to measurement of chromaticity parameters such as brightness, chromaticity, brightness uniformity, chromatic aberration and the like of light-emitting objects such as an LCD (liquid crystal display), an OLED (organic light emitting diode), a light source and the like. The imaging colorimeter converts optical signals into digital signals which can be identified by a digital programmable chip through an optical lens, a color filter, an ND filter, a CCD/CMOS image sensor and an ADC circuit, the digital programmable chip transmits the obtained digital signals to a computer through a network or a USB interface, and upper computer software performs optical and image algorithm processing on data to obtain optical parameters required by people, wherein the optical parameters comprise brightness, chroma, brightness runnability, chromatic aberration and the like. The digital programmable chip is an FPGA or a chip containing programmable logic.

In order to improve the transmission bandwidth, the same image is equally divided and transmitted through a plurality of network ports. However, when the data is transmitted through a plurality of network ports, if synchronization of each network port channel is not well done, the complexity of the upper computer for receiving the data is increased, the software in the upper computer considers which channel data is, and the splicing operation can be completed only after all the channel data are transmitted, and as the randomness of network transmission and the software in the upper computer run under a non-real-time operating system, a random time difference exists between each channel data, so that the data receiving efficiency is reduced, and the data bandwidth of the plurality of network ports and the computing resources of the upper computer are wasted.

Therefore, in order to solve the above problems, the present invention provides a transmission system and an imaging colorimeter, which are intended to solve at least partially the above problems.

Referring to fig. 1 and 2, fig. 1 and 2 show schematic structural diagrams of a transmission system in an embodiment of the present invention, and an embodiment of the present invention provides a transmission system, including: the data transmitting end 110 and the data receiving end 130 are connected through the transmission network interface 120. The data transmitting end 110 includes: a data acquisition module 112 and a data splitting module 114.

The data obtaining module 112 is connected to the data splitting module 114, and is configured to send the obtained data to the data splitting module 114. The data acquired by the data acquisition module 112 may include one or more of image data, video data, audio data, and the like. The data obtaining module 112 may obtain different types of data according to different requirements for transmitting data.

The data splitting module 114 is connected to the plurality of transmission network ports 120, and the user splits the data sent by the data obtaining module 112 into a plurality of subdata and sends the plurality of subdata through the transmission network ports 120.

The sub-data may be data obtained by splitting the data in this embodiment, for example, the data is image data, the image data may be split according to the number of rows and columns (height and width) of the image, and each image data obtained by splitting may be sub-data.

In some exemplary embodiments, taking the example of transmitting image data, the data acquisition module 112 may be a sensor driving module. As mentioned in the background, an imaging colorimeter is connected when it is desired to transmit the currently acquired image data. The sensor driving module drives a CCD/CMOS image sensor in the imaging colorimeter to indicate the CCD/CMOS image sensor to acquire image data, and after the acquisition is finished, the sensor driving module can acquire the image data.

In other embodiments, the data acquisition module 112 may also directly receive image data transmitted from other data sources.

The data receiving end 130 includes: a data merging module 132, connected to the plurality of transmission network ports 120, for receiving the sub-data through each transmission network port 120, and merging the sub-data according to the order of receiving the sub-data, so as to obtain the same data as that obtained by the data obtaining module 112.

Specifically, after the data splitting module 114 splits the data into the sub-data, the sub-data is usually sent through the corresponding transmission network ports 120 according to the splitting sequence. Therefore, after the data combining module 132 receives the data subdata in sequence through the transmission network port 120, the data combining module may combine the subdata in the received sequence to obtain the final data. For example, the sub-data is obtained by splitting the image data according to the number of lines, and the sub-data may be combined according to the received number of lines to obtain the final image data. In addition, by the method, all the sub-data can be combined when the transmission is not finished, and the transmission efficiency can be improved.

The data transmitter 110 and the data receiver 130 may be implemented by a Programmable logic device, such as an FPGA (Field Programmable Gate Array) or a custom ASIC (Application Specific Integrated Circuit) chip.

It is understood that the split data is usually data with a relatively large capacity, for example, data with a capacity of more than 500M or 1GB or more.

In the transmission system, large-capacity data is split and transmitted through a plurality of transmission network ports, so that the transmission bandwidth can be increased, and the data transmission time can be shortened. And the module is usually implemented by hardware because data is transmitted, split and combined by a data transmitting end and a data receiving end. Therefore, the split is realized in a hardware mode, and the time change is avoided. No time difference is generated in data transmission. The problem of data transmission asynchronism is solved. The efficiency of data reception is improved, and transmission resources can be utilized more reasonably. And the transmission network port is used for transmission, so that an additional transmission interface is not required to be added, the upgrading cost of the product can be reduced, and the design and use cost of the product can be reduced.

Referring to fig. 3, fig. 3 is a schematic diagram of a transmission network interface 120 of a transmission system in an embodiment of the present invention, and in some embodiments, the transmission network interface 120 includes a plurality of sending network interfaces 122 and receiving network interfaces 124 corresponding to the sending network interfaces 122.

Specifically, the multiple sending network ports 122 are connected to the data splitting module 114, and after the data splitting module 114 splits the subdata, each subdata may be sent to the receiving network port 124 through the same and/or different sending network ports 122 according to the order of the split subdata. In some preferred embodiments, the transmissions may be sent through different transmission portals 122 to increase transmission speed.

The receiving ports 124 are respectively connected to the data merging module 132 and the sending port 122, and are configured to receive the sub data transmitted by the sending port 122.

Specifically, a plurality of receiving ports 124 are connected to the transmitting port 122, and the receiving ports 124 and the transmitting port 122 are in one-to-one correspondence. Each receiving portal 124 receives the sub data transmitted by the transmitting portal 122. And then will interface with the data merge module 132. The data merge module 132 receives the sub-data through the receive portal 124.

The transmission network port 122 and the reception network port 124 are both gigabit network ports. The transmission network port 122 and the reception network port 124 are transmitted through a gigabit network.

In the present embodiment, the transmission rate can be increased by the transmission network port 122 and the reception network port 124 interacting with each other and both being gigabit network ports.

In one embodiment, as shown in fig. 4, the data transmitting end 110 further includes: a plurality of first network driver modules 116, respectively connected to the data splitting module 114 and the corresponding sending network ports 122, and configured to receive a plurality of subdata sent by the data splitting module 114; each of the first network driving modules 116 is configured to send each sub data through the corresponding sending network port 122.

Specifically, in general, the data splitting module 114 or the data merging module 132 cannot directly drive the corresponding network, and therefore, the first network driving module 116 and the second network driving module 134 are introduced. Each first network driver module 116 is connected to a corresponding transmission portal 122, and each first network driver module 116 is connected to the data splitting module 114. Each first network driver module 116 receives one or more sub-data (usually, one sub-data for increasing the transmission speed) sent by the data splitting module 114, and then sends the sub-data through the sending port 122 connected thereto. Each second network module is connected to a corresponding receiving port, and each second network driving module 134 is connected to the data merging module 132. Each second network driving module 134 receives the subdata sent by the first network driving module 116 through the sending port 122 through the receiving port, and sends the subdata to the data merging module 132.

In some exemplary embodiments, the first network driver module 116 and the second network driver module 134 may be generally PHY chips (Physical), such as DM9161AEP, RTL8201, DP83848CVV, LAN8720A, LAN8742A, etc., which may implement Physical layer communication of a computer network.

In one embodiment, as shown in fig. 5, the data receiving end 130 further includes a driving module 136, connected to the data merging module 132 and the upper computer, for sending data to the upper computer through the transmission interface.

Specifically, after the data receiving end 130 receives the sub-data and merges the sub-data into data, the data receiving end 130 needs to send the data to an upper computer, and the upper computer processes the data. Therefore, the data receiving end 130 may further include a driving module 136. The driving module 136 is connected with the data merging module 132 and the upper computer, and is configured to transmit the data obtained by merging the data merging module 132 to the upper computer through transmission and reception. And after the upper computer acquires the data, processing the data.

In some exemplary embodiments, the driver module may be a PCIE driver module in general. The PCIE driving module can send the data to the upper computer through the PCIE interface. In addition, the data receiving terminal 130 is normally installed in an upper computer. In addition, if the upper computer does not use the data receiving terminal 130 to receive data, if the data is directly merged, a time difference exists, because a WINDOWS operating system usually exists in the upper computer and a time difference exists when the instructions are executed through software, so that a non-real-time problem is caused.

In one embodiment, as shown in fig. 6, the data transmitting end 110 further includes: the first storage module 118 is connected to the data obtaining module 112 and the data splitting module 114, respectively, for storing the data.

Accordingly, the first storage module 118 and the second storage module 138 are added at the data sender 110 and the data receiver 130. The first storage module 118 is connected to the data obtaining module 112, and stores the data obtained by the data obtaining module 112. The first storage module 118 is connected to the data splitting module 114, and the data splitting module 114 can obtain the data in the first storage module 118. The second storage module 138 is connected to the data merging module 132, and when the data merging module 132 merges the sub-data to obtain data, the data may be stored.
