In some embodiments, fig. 2 is a schematic structural diagram of the display control apparatus 1 and the display screen 2 according to an embodiment of the present invention, and as shown in fig. 2, the signal output port 11 of the display control apparatus 1 can be connected to the signal input port 20 of the display screen 2 in an inline manner. It should be noted that, because of the particularity of signal transmission in the rail industry, the signal output port 11 of the display control apparatus 1 and the signal input port 20 of the display screen 2 are connected in a straight-line manner, so that the stability of signal transmission can be ensured. Specifically, the signal output port 11 of the display control apparatus 1 and the signal input port 20 of the display screen 2 are connected in a direct-plug manner by using a Harting DIN41612 connector.
In some embodiments, fig. 3 is another structural block diagram of the display control apparatus 1 according to the embodiment of the present invention, and as shown in fig. 3, the display control apparatus 1 further includes a power module 13, and the power module 13 is respectively connected to the main control module 10, the signal output port 11, and the network receiving port 12, so as to supply power to the main control module 10, the signal output port 11, and the network receiving port 12.
In some embodiments, in the case that the signal output port 11 of the display control apparatus 1 is connected to the signal input port 20 of the display screen 2, the other end of the power module 13 except for the connection with the main control module 10, the signal output port 11 and the network receiving port 12 can be connected to a backlight panel of the display screen 2, so as to supply power to the backlight panel (backlight driving module) of the display screen 2.
It should be noted that the network receiving port 12 adopts a four-core M12D snap-in connector; and an interface of the power module 13 connected with the backlight plate of the display screen 2 adopts a WAGO connector with a 4P 5.0 space. The display control device 1 and the display screen 2 which are independent of each other can realize the plug-in design through a unified standard interface, namely 2 independent modules establish a standard communication mode and a power supply mode through the standard interface.
In some of these embodiments, as shown in fig. 3, the display control apparatus 1 further includes a power management module 14; one end of the power management module 14 is connected to the power module 13, the other end of the power management module 14 is connected to the main control module 10, and when the power management module 14 detects the main control module 10, the power management module 14 controls the power management module 14 to supply power to the main control module 10. In some of these embodiments, the display screen 2 further comprises a signal conversion module; the signal conversion module is configured to convert the low voltage differential signal transmitted by the display control apparatus 1 into an HDMI signal.
In some embodiments, it should be noted that, after the display control apparatus 1 and the display screen 2 which are independent of each other are connected through a standard interface, that is, after the display control apparatus 1 and the display screen 2 are connected in an in-line manner by using a Harting DIN41612 connector, the power module 13 in the display control apparatus 1 supplies power to the backlight panel (backlight driving module) in the display screen 2 in addition to transmitting the low voltage difference signal to the display screen 2. In view of the above, in order to avoid that the power supply module 13 in the display control apparatus 1 supplying power to the backlight panel (backlight driving module) in the display screen 2 is powered down to affect the interaction between the display control apparatus 1 and the display screen 2, the power supply module 13 may be monitored by the power management module 14. In addition, the other end of the power module 13 is connected to a large-capacity power supply or can be directly connected to the commercial power, once the power management module 14 monitors that the electric quantity of the power module 13 is lower than a preset threshold, the power management module 14 can send a charging request instruction to the main control module 10, and then the main control module 10 can control the large-capacity power supply or the commercial power to charge the power module 13. It should be further noted that, in order to reduce the consumption of the backlight panel (backlight driving module) in the display screen 2 on the electric quantity of the power module 13, after the display control device 1 and the display screen 2 are connected in a direct-plug manner through the Harting DIN41612 connector, that is, after the main control module 10 establishes communication with the display screen 2, the main control module 10 sends a power request instruction to the power management module 14, and the power management module 14 wakes up the power module 13 to supply power to the backlight panel (backlight driving module) in the display screen 2 in response to the power request instruction, which one aspect of avoiding the situation that the power module 13 supplies power to the backlight panel (backlight driving module) in the display screen 2 before the display control device 1 and the display screen 2 communicate through the Harting DIN41612 connector, reduces the invalid power supply of the power module 13, reduces the consumption of the backlight panel (backlight driving module) in the display screen 2 on the electric quantity of the power module 13, the power shortage of the power module 13 can be attenuated to some extent.
An embodiment of the present invention further provides a display control system, and fig. 4 is a flowchart of the display control system according to the embodiment of the present invention, where the display control system includes a display screen 2 and a display control device 1 for controlling the display screen 2, the display screen 2 and the display control device 1 are separated from each other, and the display control device 1 is the display control device 1 in any one of the foregoing embodiments, and details are not repeated here.
The display control system is independent of the display screen 2 through the display control device 1, namely the display screen 2 and the display control device 1 are separated, and the display screen 2 and the display control device 1 are connected through the matched signal input port 20 and the signal output port 11, namely the display screen 2 and the display control device 1 are connected in a separable mode through a standard interface, so that the display control device 1 can be interchanged, and the universal matching performance of the display control device 1 is improved; compared with the traditional design scheme, the scheme is more convenient to maintain and disassemble.
