Description
Technical field
It is more particularly to a kind of that there is combustible and explosive area explosion-proof tank panel type peace the present invention relates to a kind of explosion-proof man-machine interface
The explosion-proof man-machine interface of dress, belongs to inflammable and explosive hazardous area electric automatization control field.
Background technology
Man-machine interface product used in common field is basically designed to control cabinet, switch board at present（Typically use sheet metal
Into）Panel type mount scheme.Man-machine interface for combustible and explosive area must meet the explosion-proof man-machine interface of requirement of explosion proof.
The explosion-proof control box, the switch board that are used due to combustible and explosive area are common such as flame-proof type, its shell include panel using
Thicker steel plate or cast aluminium alloy is made.Flame-proof type control cabinet, switch board are not allowed using similar due to explosion-proof particular/special requirement
Panel type installation is carried out in the mode perforate of general control case, switch board, thus it is man-machine when being needed to use in combustible and explosive area
There are two kinds of common schemes during interface at present.Scheme one, independent explosion-proof human interface devices are designed, make it independent as one
Equipment and other equipment are connected to form control system, such as the explosion-proof man-machine interface of intrinsic safety type, fill explosion-proof man-machine interface of sand mold etc.；Side
Case two, common man-machine interface product is installed on inside Flameproof box, using safety glass after perforate on Flameproof box panel
Pour seal structure and formed and meet the form of requirement of explosion proof, can observe the picture of man-machine interface by the form, but safety glass
Failed in the presence of the touch controllable function caused in man-machine interface, to realize touch controllable function, current method is to use individually designed one
The scheme of intrinsic safety Trackpad, i.e., on the outside of safety glass（On the outside of Flameproof box）Increase a Trackpad, Trackpad electrical connection is led
Line is incorporated into box house by the explosion-proof seal structure that pours, then is connected to man-machine interface by guard grating, to realize touch controllable function.
In combustible and explosive area, scheme one is applied to control program of the man-machine interface as a specific installation, sometimes
Be for anti-explosion product can not panel installation a solution.Though scheme two realize man-machine interface with it is explosion-proof case integrated
The purpose of design, but have the defects of obvious：1. man-machine interface touch-control effect is poor, due to the interval of man-machine interface picture and Trackpad
Safety glass, the thickness for the safety glass that general flame-proof type product uses is directly proportional to the area of form, i.e., windows area is got over
Greatly, required safety glass is thicker, and by taking the windows area needed for 7 cun of man-machine interfaces as an example, the thickness of its safety glass is extremely
8-10mm is wanted less, i.e., at least 8mm distance, therefore the very easy collimation error that produces causes touch-control between Trackpad and picture
Invalid or malfunction, therefore touch-control effect is deteriorated, operator, which experiences, to be deteriorated；2. the man-machine interface size that can be realized has limitation
Property, as described above when man-machine interface size is bigger, required windows area is bigger, therefore safety glass must thicken with full
Sufficient requirement of explosion proof, according to practical experience when safety glass thickness is more than more than 12mm, touch controllable function can not produced specifically substantially
Realized on product, therefore the program is suitable only for the man-machine interface of small size；3. maintenance difficult, sealed knot is poured because Trackpad uses
Structure, once Trackpad damage can not be individually replaced substantially, then product can not repair substantially causes whole product rejection or loses tactile
Control function；4. program complex process, adds production difficulty, cost increase result in.
The content of the invention
The present invention proposes a kind of explosion-proof man-machine interface with the installation of combustible and explosive area explosion-proof tank panel type, solves
The man-machine interface size that man-machine interface touch-control effect is poor in combustible and explosive area of the prior art, can realize have limitation,
Maintenance difficult and solution process are complicated, add production difficulty, the problem of result in cost increase.
