Description
Technical field
The utility model belongs to antiknock device control technology field, more particularly to a kind of explosion-proof man-machine interface.
Background technology
With the intellectuality of equipment progressively, most equipment all uses man-machine interface.And chemical plant, oil plant, mine etc. are quick-fried
Explosive and flammable material fills in fried property hazardous area, equipment and pipeline the setting off an explosion property or inflammable because of the poor sealing
Property material is excessive, the spark formed when the electric terminal and the electrical equipment short circuit that run into instrument, all may set off an explosion or burn.
Equipment and instrument resists the impulsive force of blast and heat remains to normal work without suffering a loss to enable, and need to use corresponding explosion-proof
Type instrument and electric apparatus for explosive gas.Current antiknock device is designed using explosion-proof cavity combinations mostly, complicated, installation behaviour
Make inconvenience.
The content of the invention
Problem to be solved in the utility model is to provide a kind of explosion-proof man-machine interface.
To solve the above problems, technical scheme provided by the utility model is:A kind of explosion-proof man-machine interface, including display
Shield, control the display screen and the mainboard being electrically connected with the display screen, in addition to touch-screen, be connected to the touch-screen with
Limit energy part between the mainboard, is provided with limit energy part between the touch-screen and mainboard, the explosion-proof man-machine interface is also wrapped
Explosion-proof casing is included, the touch-screen, the limit energy part, the mainboard, the display screen are all arranged at the explosion-proof casing
It is interior.
Further：The limit energy part is guard grating.
Further：The touch-screen is electric resistance touch screen.
Further：The explosion-proof casing include the bonnet positioned at rear portion, cover at it is described after the middle part that covers there is screen
The protecgulum of installing space, covered after described with the binding post for being used to install electric wire.
Further：The explosion-proof casing is wall-hanging explosion-proof housing.
In summary：The advantages of the utility model for the man-machine interface in the technical program due to provided with explosion-proof casing and every
It is quick-fried, and due to the guard grating provided with current limliting, pressure limiting between touch-screen and mainboard, ensure that the available energy of field instrument is being pacified
The external of touch-screen is realized in gamut, simple in construction, convenient operation.

Embodiment
Explosion-proof man-machine interface with reference to shown in Fig. 1-Fig. 4, including display screen 9, the control display screen 9 and with it is described aobvious
The mainboard 10 that display screen 9 is electrically connected, in addition to touch-screen 8, the limit energy portion that is connected between the touch-screen 8 and the mainboard 10
Part guard grating 7.The touch-screen 8 is electric resistance touch screen.Touch-screen 8 is by mutually transmitting signal between guard grating 7 and mainboard 10.
The explosion-proof man-machine interface also includes explosion-proof casing 5, the touch-screen 8, the limit energy part 7, the mainboard 10,
The display screen 9 is all arranged in the explosion-proof casing 5.
The explosion-proof casing 5 is wall-hanging explosion-proof housing, and the explosion-proof casing includes the bonnet positioned at rear portion, covers at institute
The middle part covered after stating has the protecgulum 6 of screen installing space, is covered after described with the binding post 1 for being used to install electric wire, described
Protecgulum 6 and bonnet are fixed by interior hexagonal cylindrical head screw assemblies 2, after cover and be provided with by cross recess coiled hair screw assemblies 4
Label 3 is grounded to be grounded.
During operation, the circuit board in touch-screen 8, which is under pressure, to be produced bias voltage and transmits signal to mainboard 10.Guard grating
7 between mainboard 10 and touch-screen 8 can bi-directional signal, and limited by current limliting and pressure limiting circuit and be sent to touch-screen 8
Energy, so as to prevent the danger energy of mainboard 10 from sealing in touch-screen 8, mainboard 10 is limited in plant failure to touch-screen 8
Energy transmission, it is external to reach good flame proof effect while convenient to operate in touch-screen 8.
For examples detailed above only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
People is can to understand content of the present utility model and implement according to this, can not limit the scope of protection of the utility model with this.It is all
The equivalent transformation done according to the utility model Spirit Essence or modification, should all cover the scope of protection of the utility model it
It is interior.
