Abstract
The invention relates to a mining ventilation calculator. The mining ventilation calculator is composed of an arithmetic unit, a controller, a memory, a keyboard, a displayer and a power source. The arithmetic unit, the controller and the memory are integrated on an integrated circuit board. One end of the integrated circuit board is directly connected with the displayer, and the displayer is used for displaying relevant content. A corresponding membrane circuit located below the keyboard is connected with a corresponding control portion on the integrated circuit board through a data line, so that the relevant content can be input. The keyboard is located above the integrated circuit board. The power source is located below the circuit board and is connected with the circuit board through a wire, so that the power source supplies power to the circuit board. According to the mining ventilation calculator, storage and calculation are achieved through the arithmetic unit and the controller. The keyboard is an input component of the calculator, and the sensing type is adopted by the keyboard. In order to reduce the size of the calculator, each key often has multiple functions. The displayer is an output component of the calculator, and the liquid crystal displayer is adopted and used for displaying a calculation result. A circuit used for automatic power-off when no operation is conducted within a certain time period is arranged in the mining ventilation calculator and is designed to be an intrinsically safe circuit.
Description
Technical field
The present invention relates to mining ventilation counter, belong to counter field.
Background technology
Current mining ventilation counter, calculation of complex, cost is high.At present should be not similarly, having is also long ago just to eliminate.
Summary of the invention

Accompanying drawing explanation
By describing in more detail exemplary embodiment of the present invention with reference to accompanying drawing, above and other aspect of the present invention and advantage will become more and be readily clear of, in the accompanying drawings:
Fig. 1 is the external structure schematic diagram of mining ventilation counter of the present invention;
Fig. 2 is the internal circuit configuration schematic diagram of mining ventilation counter of the present invention.
Embodiment
Hereinafter, now with reference to accompanying drawing, the present invention is described more fully, various embodiment shown in the drawings.But the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present invention is conveyed to those skilled in the art fully.
Hereinafter, exemplary embodiment of the present invention is described with reference to the accompanying drawings in more detail.
With reference to accompanying drawing 1,2, mining ventilation counter is made up of arithmetical unit, controller, storer, keyboard, display, power supply; What can see in appearance is shell, display and keyboard.(similar conventionally in counter, but its function changes, and is specifically designed to equipment used while surveying wind under coal mine.) as shown in Figure 2, arithmetical unit, controller, storer are integrated on a surface-mounted integrated circuit.Surface-mounted integrated circuit one end is directly connected with display, is used for showing related content; The corresponding thin film circuit in keyboard below is connected with corresponding controlling position on surface-mounted integrated circuit by data line, carries out related content input, and keyboard is positioned at the top of surface-mounted integrated circuit.Power supply, below circuit board, is connected and powers with circuit board by wire.
Mining counter is by arithmetical unit, controller and realize data storage and computing.Keyboard is the input block of counter, adopts sensor-type.For reducing the size of counter, a key usually has several functions.Display is the output block of counter, adopts liquid crystal display, for showing result of calculation.Counter power acquisition battery, battery adopts No. 5 dry cells of common 2 joints.For saving electric energy, adopt integrated circuit, timing inoperation automatic power-off circuit is equipped with in inside.Be designed to essential safe type circuit.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable changes and variation.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
