Problems solved by technology
[0003] At present, the display method of the mine explosion-proof display is relatively simple, usually one signal source corresponds to one or more mine explosion-proof displays, and the display content of the mine explosion-proof display depends on a single signal source
Therefore, the content of this display mode is fixed, that is, only the content predefined by the signal source connected to it can be displayed, so it is impossible to switch to more important display content in case of temporary needs or emergencies

Embodiment Construction
[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0038] See figure 1 , The embodiment of the present invention discloses a schematic structural diagram of a mine explosion-proof display. The mine explosion-proof display includes: a motherboard 11, a signal switcher 12, a display screen 13, and a display driver 14;
[0039] among them:
[0040] The main board 11 is used to connect with the upper computer 01, and process, store, and decode and output the update resources downloaded by the up...

The invention provides a mining explosion-proof displayer and a control method thereof. The mining explosion-proof displayer comprises a main board, a signal switcher, a display screen and a display driver. The signal switcher is provided with a signal control port and a plurality of signal input ports, the signal control port is connected with an upper computer, each signal input port is connected with a signal source, and one signal source is the main board. Thus, when content displayed by the display screen needs to be changed, the upper computer will send a switching instruction to the signal switcher, and the signal switcher controls switching of the signal source corresponding to the switching instruction according to the switching instruction. It is observed that the mining explosion-proof displayer can correspond to the multiple signal sources simultaneously, and the signal sources can be switched to one another. Thus, the mining explosion-proof displayer can be switched to display more important content according to temporary needs or in an emergency state.
Description
Technical field [0001] The invention relates to the technical field of displays, and more specifically, to a mine explosion-proof display and a control method thereof. Background technique [0002] With the development of informatization in the coal mine industry, the means of information dissemination such as propaganda, notification and warning in the work of coal mine units have become more and more diverse. Among them, as a means of multimedia display, mine explosion-proof displays have become an important device for multimedia display in the coal industry. [0003] At present, the display method of explosion-proof displays for mining is relatively simple, usually one signal source corresponds to one or more explosion-proof displays for mines, and the display content of explosion-proof displays for mines depends on a single signal source. Therefore, the display content in this display method is fixed, that is, only the content predefined by the signal source connected to it ca...
