[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0034] In the following description, it is necessary to understand that the directions or positional relationships indicated by “front”, “back”, “up”, “down”, “left”, “right”, “longitudinal”, “horizontal”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “head”, and “tail”, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are constructed and operated in specific directions. They are only for the convenience of describing the technical solution, and do not indicate that the device or element referred to must have a specific direction. Therefore, they should not be understood as a limitation on the present utility model.

[0035] Figure 1 The following is a circuit diagram of an image data acquisition device in some embodiments of the present invention. The acquisition device is used to acquire image data of security inspection equipment and send the image data to Ethernet so that the image data can be collected and summarized. Figure 1 As shown, the image data acquisition device includes a protocol conversion module 2, a control module 3 and an Ethernet communication module 4.

[0036] The protocol conversion module 2 can be connected to the security inspection equipment to obtain the image data transmitted from the security inspection equipment to the display (the image data is used to control the display content of the display). The protocol conversion module 2 is used to convert the video communication protocol of the image data and transmit the image data through the first communication protocol. Specifically, the protocol conversion module 2 obtains the image data by connecting to the security inspection equipment, wherein the video communication protocol includes at least one of the VGA communication protocol, the HDMI communication protocol and the DVI communication protocol. However, no matter what communication protocol the video communication protocol of the image data belongs to, the protocol conversion module 2 will eventually convert the communication protocol of the image data transmission into the first communication protocol to facilitate the acquisition by the control module 3.

[0037] Since the single-chip microcomputer or microprocessor included in the control module 3 is commonly configured with a USB communication interface, in order to facilitate information interaction with the control module 3 and reduce the number of unnecessary hardware settings, the first communication protocol is preferably a USB communication protocol. Of course, the first communication protocol can also be other forms of communication protocols, such as a serial port, etc.

[0038] In some embodiments, the protocol conversion module 2 includes several interface conversion modules.

[0039] It should be noted that the security inspection equipment includes a host and a display. Since there are many types of communication protocols for the host to send image data to the display, including but not limited to VGA communication protocol, HDMI communication protocol and DVI communication protocol, in order to facilitate the control module 3 to obtain image data, the communication protocol of the image data needs to be unified into the first communication protocol. Accordingly, in some embodiments, the protocol conversion module 2 includes several interface conversion modules, specifically, several interface conversion modules include but are not limited to VGA to USB module, HDMI to VGA module, DVI to VGA module, VGA to USB module, HDMI to USB module and DVI to USB module. In this embodiment, various types of protocol conversion modules can be matched with each other, and finally the image data can be sent to the control module 3 with the same communication protocol. It should be noted that the VGA to USB module, HDMI to VGA module, DVI to VGA module, VGA to USB module, HDMI to USB module and DVI to USB module can all adopt existing conversion modules on the market.

[0040] Since most of the old security inspection equipment transmits image data between the host and the display via a VGA interface. Figure 2 As shown, the plurality of interface conversion modules may include a VGA to USB module 211. The VGA to USB module 211 is connected to the control module 3 and can be connected to the security inspection device to obtain image data.

[0041] Since some old security inspection equipment transmits image data between the host and the display via a DVI interface or an HDMI interface, in some embodiments, such as Figure 2 As shown, the plurality of interface conversion modules also include an HDMI to VGA module 212 and / or a DVI to VGA module 213; the HDMI to VGA module 212 and the DVI to VGA module 213 are connected to the VGA to USB module 211, and the HDMI to VGA module 212 and the DVI to VGA module 213 can be connected to the security inspection equipment to obtain image data. In this embodiment, the communication protocol of the image data is first uniformly converted to the VGA communication protocol through the HDMI to VGA module or the DVI to VGA module, and then the communication protocol of the image data is converted to the USB communication protocol by using the VGA to USB module, so that the control module 3 can obtain it.

[0042] Since the communication between the security inspection equipment and the image data acquisition device will use at most two types of interface conversion modules, in order to save costs, in some embodiments, such as Figure 3As shown, the image data acquisition device may also include a first circuit board 5. A VGA to USB module 211, a control module 3 and an Ethernet communication module 4 are arranged on the first circuit board 5. A first card slot 51 detachably connected to the HDMI to VGA module 212 and a second card slot 52 detachably connected to the DVI to VGA module 213 are provided on the first circuit board 5; the first card slot 51 and the second card slot 52 are connected to the VGA to USB module 211. In this embodiment, when the user configures the image data acquisition device for the security inspection device, the interface conversion module can be selected according to the actual communication protocol mode of the security inspection device to transmit the image data. For example, if the security inspection device transmits the image data through the VGA communication protocol, then there is no need to install the HDMI to VGA module 212 and the DVI to VGA module 213 on the first circuit board 5. If the image data is transmitted through the DVI communication protocol, the DVI to VGA module 213 can be installed in the second card slot 52, thereby saving the cost of the utility model.

[0043] Some security inspection equipment has multiple video output interfaces. In this regard, in some embodiments, such as Figure 2 or Figure 3 As shown, the image data acquisition device may also include a first VGA interface 25, an HDMI interface and a DVI interface. The VGA to USB module 211 may be connected to a redundant VGA interface in the security inspection device via the first VGA interface 25 and a VGA data line to obtain video data, the HDMI to VGA module 212 may be connected to a redundant HDMI interface in the security inspection device via an HDMI interface 26 and an HDMI data line to obtain video data, and the DVI to VGA module 213 may be connected to a redundant DVI interface in the security inspection device via a DVI interface 27 and a DVI data line to obtain video data.

[0044] Some security inspection equipment may have a single video output interface (such as only one VGA interface). Since the security inspection equipment needs to be connected to a monitor, there is no extra interface to connect the image data acquisition device. Figure 4 As shown, in Figure 2 Based on the embodiment shown, the protocol conversion module 2 may also include a VGA distributor 22, an HDMI distributor 23 and a DVI distributor 24. The VGA distributor 22 is connected to the VGA to USB module 211 and can be connected to the security inspection equipment, the HDMI distributor 23 is connected to the HDMI to VGA module 212 and can be connected to the security inspection equipment, and the DVI distributor 24 is connected to the DVI to VGA module 213 and can be connected to the security inspection equipment. In this embodiment, the VGA distributor 22, the HDMI distributor 23 and the DVI distributor 24 can all be existing distributors on the market, and their function is to expand the communication interface. Figure 5As shown, taking the VGA distributor 22 as an example, the VGA distributor 22 includes two second VGA interfaces 221, one of which is used to communicate with the security inspection equipment through a VGA data line, and the other second VGA interface 221 is also used to communicate with the display through a VGA data line. Under the action of the VGA distributor 22, the image data acquisition device and the display can both obtain image data. The HDMI distributor 23 and the DVI distributor 24 each include two interfaces of corresponding communication protocol types, and their usage is the same as that of the VGA distributor 22, which will not be repeated here.

[0045] In order to save costs, in some embodiments, such as Figure 6 As shown, in Figure 4 Based on the embodiment shown, the image data acquisition device may further include a second circuit board 7; a VGA to USB module 211, a control module 3 and an Ethernet communication module 4 are arranged on the second circuit board 7. The HDMI distributor 23 is connected to the HDMI to VGA module 212 to form a first optional module 100, and the DVI distributor 24 is connected to the DVI to VGA module 213 to form a second optional module 200. The second circuit board 7 is provided with a third card slot 71 detachably connected to the VGA distributor 22, a fourth card slot 72 detachably connected to the first optional module 100 and a fifth card slot 73 detachably connected to the second optional module 200. The third card slot 71, the fourth card slot 72 and the fifth card slot 73 are connected to the VGA to USB module 211. In this embodiment, the VGA distributor 22, the first optional module 100 and the second optional module 200 can be selected according to actual application requirements whether to be installed on the second circuit board 7.

[0046] In some embodiments, Figure 7 As shown, the several interface conversion modules may include a VGA to USB module 211, an HDMI to USB module 214, and a DVI to USB module 215. The VGA to USB module 211, the HDMI to USB module 214, and the DVI to USB module 215 are respectively connected to the control module 3 and can be connected to the security inspection equipment to obtain image data.

[0047] Some security inspection equipment may have a single video output interface. Figure 8 Based on the embodiment shown, the image data acquisition device may further include a VGA distributor 22, an HDMI distributor 23 and a DVI distributor 24 (not shown). The VGA to USB module 211 is connected to the security inspection device through the VGA distributor 22, the HDMI to USB module 214 is connected to the security inspection device through the HDMI distributor 23, and the DVI to USB module 215 is connected to the security inspection device through the DVI distributor 24.

[0048] The control module 3 is connected to the protocol conversion module 2. The control module 3 is used to receive the converted image data.

[0049] The Ethernet communication module 4 is connected to the control module 3. The Ethernet communication module 4 is used to transmit the image data to the Ethernet. The Ethernet communication module 4 can be an existing network communication module, as long as it can communicate with the wired network, and is not limited here. In addition, the communication connection method between the Ethernet communication module 4 and the control module 3 includes but is not limited to serial port, parallel port, I2C, USB and other communication methods, as long as the image data can be sent to the existing Ethernet communication module 4 and its operation can be controlled. For details, reference can be made to the existing technology, and no further description is given here.

[0050] In some embodiments, Figure 1 As shown, the image data acquisition device further includes a housing 1 for accommodating a protocol conversion module 2 , a control module 3 and an Ethernet communication module 4 .

[0051] It can be understood that by implementing the technical solution of the present invention, it is possible to collect image data of security inspection equipment through an image data acquisition device without replacing old security inspection equipment, and send the image data to Ethernet, so that the relevant system or server can obtain image data of multiple security inspection equipment through Ethernet, which can not only effectively improve the efficiency of image data aggregation and collection, but also effectively save transformation costs and avoid waste of resources.

[0052] like Figure 8 As shown, the utility model also constructs a security inspection equipment image data acquisition system, which includes multiple image data acquisition devices provided by the embodiments of the utility model, and a server connected to each image data acquisition device via Ethernet. The server is used to collect and manage image data from multiple image data acquisition devices, so that the staff at the server end can monitor the image data of security inspection equipment located at different locations (or stations) in real time.
