Description

Technical Field

[0001] This utility model relates to the field of intelligent controller technology, and in particular to a mine-use explosion-proof and intrinsically safe intelligent controller. Background Technology

[0002] Existing mining controllers are too limited in function, either with overly simple output ports and functions, or they are controlled by a PLC and only isolate bus signals, making it difficult to achieve simultaneous isolated output of most signals in complex mining environments. Furthermore, most mining controllers are intrinsically safe, requiring additional explosion-proof carriers for use in complex environments, which greatly increases the cost. Therefore, this application proposes a mining explosion-proof and intrinsically safe intelligent controller. Utility Model Content

[0006] The intrinsically safe cavity includes a display screen, a keypad, a wireless receiver, and an information acquisition board. The keypad, display screen, and wireless receiver are all connected to the information acquisition board. A through-wall terminal connects the isolation plate and the information acquisition board. The intrinsically safe power supply, display screen, and keypad are all connected to the through-wall terminal. The through-wall terminal is also connected to a USB flange and an RJ45 flange. The information acquisition board is connected to an external wiring port.

[0009] Preferably, the intrinsically safe power supply is used to output an intrinsically safe 12V DC power supply to power the isolation board, and outputs the 12V intrinsically safe power supply to the information acquisition board through the wall-penetrating terminal.

[0010] Preferably, the display screen is a 10.4-inch touchscreen.

[0011] Preferably, the LVDS, USB, RS485 and RJ45 signals on the industrial control computer are isolated by an isolation plate and then led out to the intrinsically safe cavity through a wall-penetrating terminal. The display screen is connected to the isolated LVDS and USB signals through the wall-penetrating terminal to realize microcomputer control.

[0012] Preferably, the signal acquisition board is connected to an external port via an external wiring port to acquire external data. The acquired external data is sent to the industrial control computer via a bus, and the acquired data is directly displayed on the display screen via bus software.

[0013] Compared with existing technologies, the beneficial effects of this utility model are:

[0014] This invention, through the arrangement of a series of components, ensures that all signals of the intelligent controller are processed in the explosion-proof cavity before being output to the intrinsically safe cavity through the wall-penetrating terminal, achieving the effect of multi-signal isolation output.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-2 A mine-use explosion-proof and intrinsically safe intelligent controller includes an intelligent controller body, which includes an explosion-proof cavity and an intrinsically safe cavity. The explosion-proof cavity includes a horn-shaped opening 1, a switching power supply 2, an intrinsically safe power supply 3, an industrial control computer 4, and an isolation plate 5. The intrinsically safe power supply 3 is connected to the isolation plate 5, and the switching power supply 2 is connected to the horn-shaped opening 1, the industrial control computer 4, and the intrinsically safe power supply 3. The switching power supply 2 is used to output 12V DC power to power the intrinsically safe power supply 3 and the industrial control computer 4, and the horn-shaped opening 1 is used to input AC 127V AC power to power the switching power supply 2.

[0020] The intrinsically safe cavity includes a display screen 8, a keypad 9, a wireless receiver 10, and an information acquisition board 7. The display screen 8 is a 10.4-inch touchscreen. The keypad 9, display screen 8, and wireless receiver 10 are all connected to the information acquisition board 7. A through-wall terminal 6 connects the isolation plate 5 and the information acquisition board 7. The intrinsically safe power supply 3, display screen 8, and keypad 9 are all connected to the through-wall terminal 6. The through-wall terminal 6 is also connected to a USB flange 12 and an RJ45 flange 13. The information acquisition board 7 is connected to an external wiring port 11. The intrinsically safe power supply 3 is used to output intrinsically safe 12V DC power to power the isolation plate 5 and outputs 12V intrinsically safe power to the information acquisition board 7 through the through-wall terminal 6.

[0021] The LVDS, USB, RS485, and RJ45 signals on the industrial control computer 4 are isolated by the isolation plate 5 and then led out to the intrinsically safe cavity through the wall-penetrating terminal 6. The display screen 8 connects to the isolated LVDS and USB signals through the wall-penetrating terminal 6 to realize microcomputer control. The signal acquisition board 7 is connected to the external port through the external wiring port 11 to acquire external data. The acquired external data is sent to the industrial control computer 4 through the bus and the acquired data is directly displayed on the display screen 8 through the bus software. Through the setting of a series of components, this utility model ensures that all signals of the intelligent controller body are processed in the explosion-proof cavity before being output to the intrinsically safe cavity through the wall-penetrating terminal 6, achieving the effect of multi-signal isolation output. This makes the signal transmission stability of the intelligent controller body very reliable, convenient and easy to operate, and does not require the addition of an additional explosion-proof carrier, thus reducing the cost of use.

[0022] Working principle: AC 127V AC power is input through the horn port 1 to power the switching power supply 2. The switching power supply 2 outputs 12V DC power to power the intrinsically safe power supply 3 and the industrial computer 4. At the same time, the intrinsically safe power supply 2 outputs intrinsically safe 12V DC power to power the isolation board 5. Then, the 12V intrinsically safe power is output to the signal acquisition board 7 through the wall terminal 6 to power it. The industrial computer 4 is connected to the USB flange 12 and RJ45 flange 13 through the isolation board 5 and the wall terminal 6 to the outside. It can be used by directly plugging in USB or RJ45 from the outside.

[0023] During use, the isolation plate 5 isolates the LVDS, USB, RS485, and RJ45 signals of the industrial control computer 4 and then inputs them to the signal acquisition board 7, display screen 8, keypad 9, and wireless receiver 10 via the wall-penetrating terminal 6. The display screen 8 realizes microcomputer control by connecting the isolated LVDS and USB signals. At the same time, the user can directly operate the industrial control computer 4 through the keypad 9. The external wiring port 11 is connected to the signal acquisition module 7 through the connecting cable. The signal acquisition module 7 collects data through the external wiring port 11 and the collected data is directly input into the signal acquisition module 7. At the same time, the signal is sent to the industrial control computer 4 through the bus and the collected data is directly displayed on the display screen 8 through the bus software. Since all signals are processed in the explosion-proof cavity before being output to the intrinsically safe cavity through the wall-penetrating terminal 6, the signal transmission stability of the intelligent controller body is very reliable and the operation is convenient and easy. No additional explosion-proof carrier is required, reducing the cost of use.
