Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and particularly relates to an interactive control data cable or docking station structure for large medical equipment. Background Art

[0002] Large medical equipment (such as X-ray machines / CT machines, etc.) is expensive and has a long service life. Once purchased and installed, it is used for at least 5 - 10 years, and in many cases, 20 years or even longer. If more intelligent functions are needed during the process, one can only wait for the manufacturer to upgrade the software or replace the new equipment. However, with the rapid development of information technology in today's world, artificial intelligence and the Internet of Everything in China have quietly entered various industries. It is very difficult to quickly realize the intelligent use of existing large medical equipment, and most medical imaging equipment is an intranet device and cannot be safely connected to the Internet.

[0003] Since the communication protocol of USB is a master-slave relationship, in theory, all USB devices should be controlled by the host computer, and two computers cannot communicate crosswise through a direct connection of USB male-to-male. To solve this problem, in the invention patent application with the application number CN202110476225.4, two network cards are used to achieve the communication of USB male-to-male, so as to realize mouse control and data copying. However, large medical equipment is basically an intranet device, and using a network card connection is likely to allow criminals to invade through the host computer and obtain the data of the slave computer. In terms of video acquisition and signal transmission, there are already many user-friendly designs, and it can be made driver-free and miniaturized. For example: the invention patent application with the application number CN202310218766.6 discloses a USB video capture card based on FPGA and its working method, and the invention patent with the patent number ZL201511005697.2 discloses a data acquisition method for a USB driver-free video capture card. However, this type of technology mainly solves the problem of acquisition input, and the signals it acquires are all HDMI signals, and the addition of an HDMI acquisition signal line increases the complexity, while the available HDMI interfaces of existing large medical equipment are often occupied. Therefore, the above-mentioned existing technologies are not applicable to the data transmission of large medical equipment. Summary of the Invention

The RS232 serial port signal mutual transmission circuit 6 is used to realize the communication between the first USB 3.0 splitter 3 and the second USB 3.0 splitter 4 in the form of serial port signals. The HDMI signal acquisition and conversion circuit 7 is used to receive the signals sent by the second USB 3.0 splitter 4, so as to simulate a group of HDMI screen projection signals and send them to the host computer. The first USB 3.0 splitter 3 is respectively connected with a plurality of devices to be controlled in the large medical device examination room through a USB radio frequency transmission module 8.

[0058] For the interactive control data cable or docking station structure of large medical equipment of the present invention, through the reasonable selection of components, the power consumption is reduced and the power supply stability of the power supply is optimized. In order to prevent all the HDMI interfaces of the device from being used up, a secondary conversion route is specifically designed. Since the USB is designed in a master-slave relationship and does not allow two computers to directly use USB to transmit video signals, but currently the HDMI signal acquisition circuit can be made very small, so the conversion of HDMI signals in the USB line can also be miniaturized. Apparently, the host computer acquires the picture of the slave computer through USB, but actually it is a process in which the USB simulates the display card to output HDMI signals to the video acquisition circuit; a USB radio frequency transmission module is added in the data cable or docking station because when large medical equipment performs photographic examinations, it is necessary to control auxiliary devices such as the switch of the radiation shielding door, play prompt voices, control the height of the detector, and the switch of the turnstile. Therefore, the intelligent control program can complete the control of most auxiliary devices (i.e., devices to be controlled) through the USB radio frequency transmission module, thereby intelligently controlling the entire inspection process.

[0059] Combined with the reference to Figure 8 As shown in the figure, the specific scenario where the interactive control data cable or docking station structure of large medical equipment of the present invention is applied to automatic and self-service chest radiography is as follows: To realize the automatic shooting of chest radiographs of a certain brand of X-ray machine, the dedicated intelligent control program of the present invention only needs to Figure 8 brush the patient information barcode at.D, and then at Figure 8.The master computer can be operated with one key: when the one-key operation is confirmed, the software starts to obtain the patient's RIS information through the internal network and through the data cable of the present invention Figure 8 .Q Control Figure 8 .F The slave computer (chest radiograph machine) fills in the content with the mouse and keyboard, selects the shooting conditions, and radio frequency control Figure 8 .C Gate, radio frequency control Figure 8 .L The speaker reminds the patient to enter and guides the patient to assume the position and posture, and radio frequency control to turn off the radiation Figure 8 .E Shielding door, artificial intelligence model judges whether the position is correct or makes adjustments Figure 8 .I Detector position, confirm authorized exposure, trigger Figure 8 .G Voice breath-holding prompt, after exposure Figure 8 .L The speaker prompts and opens the shielding door, control Figure 8 .F The slave computer returns to the interface waiting for inspection and a series of operations.
