Abstract
The utility model discloses an analog instrument panel for engineering machinery. The analog instrument panel comprises an input module, a main control module, a key input module, an RS232 communication module, a relay power output module, a display driving module, a buzzer and a liquid crystal display module. The main control module is connected with the input module, the key input module, the relay power output module and the RS232 communication module. The RS232 communication module is connected with the display driving module. The display driving module is in an external connection with the buzzer and the liquid crystal display module. The analog instrument panel adopts a TFT color display screen, and corresponding instrument can be displayed according to different requirements. A pointer type instrument can be displayed, and digit display can be also realized. Display is visual and marked, integral moulding is beautiful, size is small, quality is light. Removal of connecting lines on the back of the circuit board is labor-saved and time-saved, and figure interfaces of the display instrument can be switched. The analog instrument panel is simple in operation, low in cost, convenient in use and is easy to popularize.
Description
Technical field
The utility model relates to a kind of panel board, and specifically a kind of engineering machinery analog meter dial plate, belongs to engineering mechanical instruments disk technology field.
Background technology
At present, known engineering machinery is all to install the circuit board top a perforate concentratedly with the little table of some block pointer formulas, the large table of some block pointer formulas and some pilot lamp etc. with working condition indicating instrument dish, adds the connecting line of back of circuit board and forms panel board.
