Magnetic control type information recording equipment and recording method thereof

Abstract

The invention discloses magnetic control type information recording equipment and a recording method thereof. The structure of the magnetic control type information recording equipment comprises a plurality of display units arranged on the same plane in array arrangement and used for displaying information, wherein the structures of the respective display units are the same; each display unit comprises a main cavity capable of displaying two different signals, and a magnetic control plate arranged on one side of the main cavity and used for controlling the main cavity for signal display; and when the information displayed by the main cavity needs to be changed, the magnetic control plate generates magnetic field control through consuming electric energy and changes the information displayed by the main cavity, and then power failure is performed after the information is changed, so that the information does not disappear. The magnetic control type information recording equipment has the beneficial effects that by taking colors as signals, a permanent magnet, an iron core and an adsorption layer are attracted to each other, so that the signals do not disappear in a power-failure condition; and the signal switching control is facilitated through the magnetic control plate.

Description

technical field [0001] The invention relates to the field of information display equipment, in particular to a magnetically controlled information recording equipment and a recording method thereof. Background technique [0002] There are currently two ways to record and display information. One is to write text directly on paper with a pen without using electricity. The advantage of this method is that it is simple and fast, and does not require power supply, but the disadvantage is that it cannot be modified after leaving traces ; [0003] The second is to use electronic products, such as screens, monitors, and display screens. The advantage of this method is that the displayed information can be adjusted in real time, but the disadvantage is that the display of information requires a long-lasting power supply. The message disappears immediately. [0004] The former is suitable for situations where the information is never modified, the latter is suitable for situations ...

Problems solved by technology

[0002] There are currently two ways to record and display information. One is to write text directly on paper with a pen without using electricity. The advantage of this method is that it is simple and fast, and does not require power supply, but the disadvantage is that it cannot be modified after leaving traces ;

[0003] The second is to use electronic products, such as screens, monitors, and display screens. The advantage of this method is that the displayed information can be adjusted in real time, but the disadvantage is that the display of information requires a long-lasting power supply. message disappears immediately

[0004] The former is suitable for situations where the information is never modified, the latter is suitable for situations where the information is modified in real time, and for some situations that require information to stay for a certain period of time and then change, such as electronic information signs on expressways, warning signs or road construction deceleration Brand; equipment maintenance personnel information, maintenance time, these information will not change within a certain period of time, usually people use electronic displays to display constant information through continuous power supply, but this method will consume power, so now we need a A device that can consume power when the information is modified, but does not consume power when the information remains unchanged and continuously displayed
