The present invention will be further described with reference to the following description and embodiments.
As shown in fig. 1 to 2, an automatic switching control system for a multi-port and multi-host medical display includes a display 100, where the display 100 includes an input device, a USB hub module 2, a USB automatic switching module 3, at least two computers 4, a display driving motherboard 5 and a display screen 6, where the input device is connected to the USB automatic switching module 3 through the USB hub module 2, the USB automatic switching module 3 is connected to each of the computers 4 through a USB cable, each of the computers 4 is connected to a video input interface of the display driving motherboard 5, the display driving motherboard 5 is connected to the display screen 6, the display driving motherboard 5 includes a display MCU51 and a data storage 52 connected to the display MCU51, and the USB automatic switching module 3 is connected to a GPIO2 port 2 of the display MCU51, respectively, And a GPIO3 port and a GPIO4 port are connected.
As shown in fig. 1 to 2, the input device includes a touch screen 11, a USB mouse 12, and a USB keyboard 13.
As shown in fig. 1 to 2, the USB automatic switching module 3 includes a U2 chip, an EN pin of the U2 chip is connected to a GPIO4 port of the display MCU51, an S1 pin of the U2 chip is connected to a GPIO2 port of the display MCU51, and an S0 pin of the U2 chip is connected to a GPIO3 port of the display MCU 51.
As shown in fig. 1 to 2, the U2 chip is PIUSB 14-ALE.
As shown in fig. 1 to fig. 2, a GPIO1 port of the display MCU51 is connected to a switch K1 and then to ground, and a GPIO1 port of the display MCU51 is connected to a resistor R1 and then to a power supply.
The utility model provides a pair of automatic switch-over control system of many net gapes many host computers medical display, its theory of operation as follows:
1, as shown in fig. 1, 4 computers 4 are installed in the display 100, and the computers 41, 42, 43, 44, 4 computers 4 can be independently connected to different networks. The networks are isolated from each other. The display driving main board 5 has 4 video input interfaces. The display 100 can display the video contents of different computers 4 respectively. All 4 computers 4 can work simultaneously.
2, when the display MCU51 is powered on and reset, the display MCU51 and the peripheral devices are initialized, and then the data of the previous video input interface is read from the data storage 52. If the video input signal of the computer 41 is not checked, it indicates that the computer 41 has no signal input. If the input signal of the computer 41 is normal, the input video of the computer 41 is displayed. Then, the GPIO2 and the GPIO3 of the display 100 input the corresponding potential data of the input interface of the computer 41, and the data is that both the GPIO2 and the GPIO3 are at a low potential. (it is seen from the logic diagram of the circuit diagram of the USB automatic switching module 3 that both GPIO2 and GPIO3 are low potentials) after the pins GPIO2 and GPIO3 of the display MCU51 output a low potential, the potentials of pins 2 and 14 of the chip U2 of the USB automatic switching module 3 are also low potentials. Then the GPIO4 pin of the display MCU51 outputs a low potential to turn on the USB automatic switching module 3. The USB cable connected to the computer 41 is thus connected to the USB of the USB hub module 2. The USB cables of the USB mouse 12 and the USB keyboard 13 are connected to the USB of the computer 41 through the touch screen 11 of the connected monitor. Thus, the touch screen 11, the USB mouse 12 and the USB keyboard 13 can control the computer 41.
3, when the GPIO1 of the display MCU51 detects a low potential, the video signal input is detected by the computer 42, the computer 43, the computer 44 and the computer 41 respectively in sequence, and the detection is performed 1 time after 1 time. The potentials of the GPIO2 and the GPIO3 are then configured in accordance with the logic diagram of the circuit diagram of the USB auto-switching module 3. This allows pairing the current display video with the corresponding control touch 11 screen. The USB cables switched to the touch screen 11, the USB mouse 12 and the USB keyboard 13 of that computer are connected to that computer. Automatic control switching is realized.
The utility model provides a pair of automatic switch-over control system of many net gapes many host computers medical display, the video input that can the different computers of automated inspection 4 and the touch-sensitive screen 11 that corresponds, USB mouse 12 and USB keyboard 13's automatic switch-over need not relapse the plug.
