Array valve

Abstract

The invention provides an array valve, which comprises a plurality of valve groups and a control module, wherein each valve group is used for controlling corresponding control points and comprises more than N electrorheological fluid monomer valves which are connected in series, and N is not less than 2; and the control module comprises a plurality of control lines and switching tubes for controlling the control lines; each valve group is penetrated by N control lines; each electrorheological fluid monomer valve in each valve group corresponds to one control line; and the control module is used for controlling the on / off of a corresponding valve group through a switching tube via the control line. A mode of connecting the electrorheological fluid monomer valves in series is changed into acontrol mode that each control line needs a switching tube; by the array valve, on the basis of greatly reducing the number of the switching tubes, each valve is independently controlled; on one hand, the system cost is reduced; and on the other hand, the heat of the switching tubes is greatly reduced, so that the heat dissipation problem is solved.

Description

technical field [0001] The invention relates to an array valve, in particular to an array valve based on electrorheological fluid. Background technique [0002] With the popularization of computer and network technology, the information age has come. However, for the visually impaired, they mainly use electronic information through listening, and it is difficult to enjoy the joy of reading. [0003] In order to establish a harmonious society with "information barrier-free" and meet the reading needs of the visually impaired, it is necessary to convert electronically stored data into Braille character display, that is, e-books for the blind. Each character of a Braille character consists of 1 to 6 protruding dots arranged in a rectangle with 6 dots. To display Braille characters, it is necessary to solve problems such as how to control the dot protrusions, the size of e-books for blind users, and heat dissipation. . [0004] In order to intelligently control the bulge of th...

AI Technical Summary

Problems solved by technology

At present, due to the inability to solve the problem of heat dissipation under the limited size of blind e-books, it is limited to produce e-books with single-line output, and the price is as high as 50,000 yuan, which is difficult to popularize

[0006] Similar to the development bottleneck of blind e-books, in order to independently control several points in a limited size, it is necessary to configure corresponding electrorheological fluid valves and corresponding switching tubes for each point, which will involve manufacturing costs, heat dissipation, etc. question
