Abstract
The utility model discloses a keyboard device of a mining explosion suppression and essence safety type vacuum combination switch, which comprises an intrinsic safety cavity. A matrix keyboard is installed on a front panel of the intrinsic safety cavity, an intrinsic safety communication board electrically connected with the matrix keyboard is installed in the intrinsic safety cavity, a terminal insulated with the intrinsic safety cavity is installed on a back cover plate of the intrinsic safety cavity, and the intrinsic safety communication plate is connected with one end of the terminal through a communication bus. The intrinsic safety communication plate and all the independent control keys of the existing mining explosion suppression and essence safety type vacuum combination switch are integrated, so that the keyboard device is more convenient to operate, all the keys of the matrix keyboard and the intrinsic safety communication plate are in the same intrinsic safety cavity, and material consumption of equipment is saved.
Description
Technical field
The utility model relates to a kind of mine flameproof and intrinsic safety type vacuum combination switch, relates in particular to a kind of key board unit of mine flameproof and intrinsic safety type vacuum combination switch.
Background technology
As shown in Figure 1; Mine flameproof and intrinsic safety type vacuum combination switch generally comprises industrial computer, PLC, intrinsic safety communication board, control button and several protected locations; Adopt the RS-485 interface to carry out communication between industrial computer, PLC and the protected location, and the communication between PLC and control button and the protected location to be passed through the transfer of intrinsic safety communication board.Can carry out the setting of parameter, control mode and operating state as required through the control button; In the industrial computer menu, select needed function then; Industrial computer sends the required function command signal to PLC after confirming function; PLC is transmitted to each protected location by the intrinsic safety communication board and sends enabling signal to intrinsic safety communication board sending function initiating signal then.After each protected location started completion, its running status separately was transferred to industrial computer through intrinsic safety communication board and PLC more successively, and this moment, industrial computer just can show each protected location running status and parameter.The control button of common existing mine flameproof and intrinsic safety type vacuum combination switch is made up of the button that several independently disperse; Therefore operation inconvenience; And for satisfying the requirement that equipment has the flame proof function in the Safety of Coal Mine Production process; Need install a flameproof enclosure additional to each button that independently disperses of the control button of existing mine flameproof and intrinsic safety type vacuum combination switch, so just increase the material consumption of equipment.
The utility model content
The purpose of the utility model is to provide a kind of key board unit of being convenient to operate and economize on the mine flameproof and intrinsic safety type vacuum combination switch of material.
For achieving the above object; The utility model provides a kind of key board unit of mine flameproof and intrinsic safety type vacuum combination switch; Comprise an intrinsic safety cavity, on the front panel of said intrinsic safety cavity matrix keyboard is installed, the intrinsic safety communication board that is electrically connected with said matrix keyboard is installed in the said intrinsic safety cavity; Binding post with its insulation is installed on the back shroud of said intrinsic safety cavity, and said intrinsic safety communication board links to each other with an end of said binding post through communication bus.
The key board unit of the mine flameproof and intrinsic safety type vacuum combination switch of the utility model, said matrix keyboard is the 4*4 matrix keyboard.
The key board unit of the mine flameproof and intrinsic safety type vacuum combination switch of the utility model, said 4*4 matrix keyboard is fixed on the said front panel through bolt is embedded.
The key board unit of the mine flameproof and intrinsic safety type vacuum combination switch of the utility model, said binding post is provided with a plurality of, and an end of each said binding post is positioned at said intrinsic safety cavity, and the other end stretches out said intrinsic safety cavity.
The key board unit of the mine flameproof and intrinsic safety type vacuum combination switch of the utility model comprises an intrinsic safety cavity; On the front panel of intrinsic safety cavity matrix keyboard is installed; The intrinsic safety communication board that is electrically connected with matrix keyboard is installed in the intrinsic safety cavity; Binding post with its insulation is installed on the back shroud of intrinsic safety cavity, and the intrinsic safety communication board links to each other with an end of binding post through communication bus.The intrinsic safety communication board that is about to existing mine flameproof and intrinsic safety type vacuum combination switch becomes one with each discrete control key sets; Not only be more convenient for like this operating; And all buttons of matrix keyboard and intrinsic safety communication board are in an intrinsic safety cavity, the material consumption of having saved equipment.

Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model:
Referring to figs. 2 and 3 shown in; The key board unit of the mine flameproof and intrinsic safety type vacuum combination switch of present embodiment comprises an intrinsic safety cavity 4 that is roughly rectangle; On the front panel 6 of intrinsic safety cavity 4 through the embedded 4*4 matrix keyboard 1 that is equipped with of bolt; The intrinsic safety communication board 7 that is electrically connected with 4*4 matrix keyboard 1 is installed in the intrinsic safety cavity 4; At least two binding posts 2 with its insulation are installed on the back shroud 5 of intrinsic safety cavity 4, and (one is used for linking to each other with the PLC of mine flameproof and intrinsic safety type vacuum combination switch; And other be used for link to each other with the protected location of mine flameproof and intrinsic safety type vacuum combination switch, the number of binding post 2 is decided according to the number of protected location), an end of each binding post 2 is positioned at intrinsic safety cavity 4; And the other end is positioned at and stretches out intrinsic safety cavity 4, and intrinsic safety communication board 7 links to each other with an end that is positioned at intrinsic safety cavity 4 of each binding post 2 through communication bus 3 correspondences.
During use; The key board unit of the mine flameproof and intrinsic safety type vacuum combination switch of present embodiment embedded is installed on the panel of mine flameproof and intrinsic safety type vacuum combination switch; And the outer ends of intrinsic safety cavity 4 that are positioned at of one of them binding post 2 are linked to each other with the PLC of mine flameproof and intrinsic safety type vacuum combination switch, other binding posts 2 be positioned at the outer end of intrinsic safety cavity 4 then correspondence link to each other with the protected location of mine flameproof and intrinsic safety type vacuum combination switch and get final product.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection range that claims of the utility model confirm.
