The invention provides an automatic switching control system of a multi-network-port multi-host medical display, which has the working principle 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 automatic switching control system and method for the multi-network-port multi-host medical display can automatically detect the video input of different computers 4 and the automatic switching of the corresponding touch screen 11, USB mouse 12 and USB keyboard 13, and do not need to be repeatedly plugged and unplugged.
