Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of underground coal mine computers, in particular to a large-screen display computer underground in a coal mine. Background Art
[0002] In some special environments (such as coal mines), there are a large number of flammable and explosive gases. In order to prevent these gases from exploding due to sparks generated when general equipment is working, people have developed a variety of special equipment for use in coal mines. Among them, explosion-proof computers are one of the most widely used special equipment in coal mines.
[0003] In existing explosion-proof computers: the display and the host are generally designed as an integrated whole, or the host and the display are assembled together through an explosion-proof cover. This design method will reduce the production cost of the explosion-proof computer. However, when the host and the display are concentrated in a smaller area, the heat dissipation effect of the host and the display will be affected. On the other hand, the data exchange interface on the host is located inside the explosion-proof cover, which limits the data exchange function of the industrial computer. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a large-screen display computer for underground coal mines.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A large-screen display computer in a coal mine comprises a rubber-sealed intrinsically safe display, a flameproof intrinsically safe host and an intrinsically safe keyboard. The rubber-sealed intrinsically safe display and the flameproof intrinsically safe host are connected by optical fiber cables, and the flameproof intrinsically safe host and the intrinsically safe keyboard are connected by explosion-proof cables.
[0007] Preferably, the glue-sealed and intrinsically safe display comprises a display body, on which a display flameproof quick-plug interface is provided, and the display flameproof quick-plug interface comprises a display flameproof quick-plug optical port and a display flameproof quick-plug power port.
[0008] Preferably, the adhesive-sealed and intrinsically safe display comprises a group of LED light strip structures, and the adhesive-sealed and intrinsically safe display is powered by an intrinsically safe V power supply.
[0009] Preferably, the flameproof and intrinsically safe host includes a host body, on which a host flameproof quick-plug interface and a host flameproof cable interface are provided, and the host flameproof quick-plug interface includes a host flameproof quick-plug network port, a host flameproof quick-plug optical port, a host flameproof quick-plug power port, a host flameproof quick-plug USB interface and a host flameproof quick-plug communication interface.
[0010] Preferably, the intrinsically safe keyboard adopts a quick-plug structure to be connected to the flameproof quick-plug interface of the flameproof and intrinsically safe host.
[0011] The beneficial effects of the utility model are:
[0012] 1. In the explosion-proof computer, the rubber-sealed intrinsically safe display and the flameproof intrinsically safe host communicate through optical fiber cables, which can transmit over a longer distance. The rubber-sealed intrinsically safe display and the flameproof intrinsically safe host have good heat dissipation effects and small signal attenuation, which can ensure the stability and reliability of the video signal; optical fiber cable communication is not affected by electromagnetic interference, has high anti-interference ability, and can ensure the confidentiality and stability of the signal.
[0013] 2. The glue-sealed and intrinsically safe display adopts a cast-sealed design and an intrinsically safe design, which can effectively protect the non-safe circuit and avoid direct contact between the non-safe circuit and the gas in the coal mine and cause accidents; the cast-sealed design and the intrinsically safe design are adopted, and the product shell can be designed as an intrinsically safe shell, which can effectively reduce the weight of the equipment, and the installation and movement are better than flameproof and intrinsically safe equipment, and the volume can be reduced at the same time; the cast-sealed design can effectively prevent dust, water vapor and corrosive gas from entering the interior of electrical equipment, which can more effectively protect electronic equipment.
[0014] 3. The glue-sealed and intrinsically safe display is composed of 4 sets of LED light strips and powered by intrinsically safe 12V. The 4 sets of light strip rings can automatically adjust the brightness and color temperature of the screen by sensing the color and intensity of the ambient light to provide the best viewing experience; at the same time, it can also prevent the constant current source from generating a large transient current at the moment of startup, causing the 12V intrinsically safe power supply to be protected and a black screen to occur.
[0015] 4. The flameproof and intrinsically safe host is provided with a host flameproof quick-plug interface and a host flameproof cable interface. The host flameproof quick-plug interface includes a host flameproof quick-plug network port, a host flameproof quick-plug optical port, a host flameproof quick-plug power port, a host flameproof quick-plug USB port and a host flameproof quick-plug communication interface. The host flameproof cable interface is used for the access of other devices. Through these flameproof interfaces, the data exchange function of the industrial computer can be improved to a limited extent.
[0016] 5. The explosion-proof and intrinsically safe host adopts explosion-proof and intrinsically safe design, which improves its explosion-proof performance. BRIEF DESCRIPTION OF THE DRAWINGS
