Description

Technical Field

[0001] The utility model relates to the technical field of mining screens, in particular to a spliced ​​mining intrinsically safe intelligent large screen. Background Art

[0002] Intrinsically safe type is an explosion-proof type of electrical equipment. It limits the energy of electric sparks or thermal effects that may be generated by connecting wires inside the equipment and exposed to potentially explosive environments to a level that cannot cause ignition, so that the electric sparks and thermal effects generated by the equipment under normal operation and specified fault conditions cannot ignite the explosive mixture in the surrounding environment. This type achieves the purpose of explosion protection by limiting various parameters of the circuit of the electrical equipment or taking protective measures to limit the spark discharge energy and thermal energy of the circuit. Electrical equipment that uses intrinsically safe circuits is called intrinsically safe electrical equipment. Its circuit itself has explosion-proof performance and is essentially safe.

[0003] At present, many mining areas use intrinsically safe LCD screens to display the conditions in every corner of the mining area. Fang Boni checked in time and found that intrinsically safe LCD screens are generally used in coal mines, metal and non-metal mines, petrochemicals, natural gas and other fields. However, the current intrinsically safe LCD screens are installed at a fixed height and cannot be flexibly adjusted. This is inconvenient for the complex terrain of the mining area.

[0004] The patent with announcement number CN202003651U discloses a large-size intrinsically safe liquid crystal display screen for use in mines. It mainly solves the problem that large-size liquid crystal display screens have too much power consumption and cannot be used in coal mines. It is characterized in that: the liquid crystal display screen also includes a parallel organic light-emitting diode backlight array, a backlight power supply circuit and a backlight control circuit; wherein the organic light-emitting diode backlight array serves as the backlight light source of the liquid crystal screen and outputs an image display signal to the liquid crystal screen; the backlight power supply circuit is composed of an input circuit, a conversion circuit and an output circuit, and the backlight control circuit is composed of a reference power supply circuit, a sampling circuit, a comparison amplifier circuit, a V / F conversion circuit, an oscillator, and a base drive circuit; the backlight control circuit modulates the rectangular pulse according to the modulation signal provided by the digital signal drive circuit, controls the switching frequency of the diodes in the organic light-emitting diode backlight array, and simultaneously adjusts the output current to control the brightness of the diodes. This type of liquid crystal display screen has low power consumption and can be used in coal mines.

[0005] However, the above-mentioned intrinsically safe LCD screen cannot be spliced, which is limited when more content needs to be displayed.
