Abstract
The utility model discloses an LED display screen with a clock control device. The LED display screen comprises an LED screen body, a dial, pointers and the clock control device for controlling the rotation of the pointers. The clock control device comprises a controller and a stepping motor which is connected with the controller and drives the pointers to rotate. The controller is a programmable logic controller (PLC), and the stepping motor is connected with a pulse output port of the PLC. The clock control device further comprises a key connected with the controller. The LED display screen with the clock control device is good in display effect and easy to control.
Description
Technical field
The utility model relates to a kind of LED display with clock control device.
Background technology
At the big screen display screen of cue ball field use, only have for the electronics dial plate of displaying time with for the display screen that shows than the data of grading, but electronics dial plate sharpness is not high, therefore be necessary to show a kind of novel LED display.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of LED display with clock control device, should be good with the LED display display effect of clock control device, be easy to control.
The technical solution of utility model is as follows:
A kind of LED display with clock control device comprises LED screen, dial plate, indicator and is used for controlling the clock control device that indicator rotates; Described clock control device comprises controller and the stepper motor that is connected with controller, and stepper motor drives indicator rotation (stepper motor can by necessary gear train such as gear mechanism table-drive needle movement, be prior art).
Described controller is PLC, and stepper motor is connected with the pulse output end mouth of PLC.
Described clock control device also comprises the button that is connected with controller.
Button is used for PLC is resetted and is used for setup times etc.The LED screen is used for showing numeral or word.This LED display with clock control device is particularly useful for score and the time showing in football pitch.
Beneficial effect:
LED display with clock control device of the present utility model, due to employing indicator and this traditional mechanical mode displaying time of dial plate, thereby more clear than electronics dial plate and electronics indicator, and, adopt stepper motor and PCL as driver module, control accuracy is high, and easy to implement.
