Detailed Description
Example 1
As shown in fig. 1 and 2, the automatic lottery pointer comprises a barrel-shaped shell 1, a stepping motor 2 fixed in the barrel-shaped shell, a pointer 3 driven by the stepping motor 2, and a controller 4 in the barrel-shaped shell, wherein a zero clearing pulse generating mechanism is further arranged in the barrel-shaped shell 1, a zero clearing pulse generated by the zero clearing pulse generating mechanism is input into the controller 4, and an output end of the controller 4 is connected with the stepping motor 2 through a stepping motor driver. In use, the output signal of the controller 4 is directed out of the barrel housing 1 in order to configure a display screen and/or a larger speaker. The zero clearing pulse generating mechanism is composed of a U-shaped photoelectric sensor 5 and a zero clearing trigger needle 6. In specific implementation, one end of the pointer 3 is provided with a rotating shaft perpendicular to the pointer 3, and a zero trigger needle 6 in the zero clearing pulse generating mechanism is vertically fixed on the rotating shaft. During specific implementation, a key is connected to the input end of the controller 4, the key is pressed, the controller 4 receives a key pressing signal, the controller 4 sends out continuous stepping pulses under the support of corresponding software, the key is released, and the controller 4 stops sending out the stepping pulses. Obviously, the rotation speed of the stepping motor should be higher than the dynamic visual acuity (dynamic vision) of the human body to prevent the lottery result from being artificially controlled.
When in use, the automatic lottery drawing rotary needle is arranged or fixed at the central position of the prize-giving disk in cooperation with the prize-giving disk printed by the printer; the automatic lottery drawing rotary needle can also be fixed on the simulation lottery disc on the display screen; and output equipment such as a display screen, a loudspeaker and the like connected with the output signal of the controller can realize lottery drawing. When the automatic counting machine works, a key is pressed, the controller 4 receives a key pressing signal, the controller 4 sends a continuous stepping pulse signal under the support of corresponding software, the stepping pulse signal enables the stepping motor to work through a stepping motor driver, and then the pointer 3 is driven to rotate around a prize-item disc at a high speed, the controller 4 counts the sent stepping pulse signal, the return-to-zero trigger needle 6 triggers the U-shaped photoelectric sensor 5 once, the U-shaped photoelectric sensor 5 sends a pulse signal to the controller 4, the controller 4 receives the pulse signal sent by the U-shaped photoelectric sensor 5, and the stepping pulse signal is counted, cleared and starts counting again; the key is released, after the controller 4 receives the key release signal, the controller 4 stops sending the stepping pulse signal, and the stepping motor stops rotating; the total number of the stepping pulses required by the stepping motor to rotate for one circle is fixed, and the stepping angle of the stepping motor corresponding to each stepping pulse is determined; the angle of each prize area on the prize disk and the number of the occupied stepping pulses are fixed, the controller 4 calculates the prize area pointed by the pointer 3 according to the number of the last non-full-circle stepping pulse signals and by combining the number of the stepping pulses occupied by each prize area on the prize disk, for example, the total number of the pulses required by one rotation of the stepping motor is 3600, the stepping angle of the stepping motor =360 °/3600=0.1 °, which represents that one stepping pulse stepping motor rotates 0.1 °, if the prize disk 2 is divided into three mutually adjacent fan-shaped prize areas, the number of the stepping pulses of the first prize area is 0 to 1199 from the zero position where the return-to-zero trigger needle 6 triggers the U-shaped photoelectric sensor 5, the number of the stepping pulses of the second prize area is 1200 to 2399, the number of the stepping pulses of the third prize area is 2400 to 3599, and by combining the number of the last non-full-circle stepping pulse signals counted by the controller after the stepping motor stops rotating, judging the prize area where the pointer 3 is located; the controller then outputs the lottery result signal and sends it to the loudspeaker and the display screen respectively to display or play the lottery result. As can be seen from the detailed working process, the whole control process is a conventional control, and therefore, the control software required by the controller is easily realized by those skilled in the art.
Further, since the stepping motor is controlled by the stepping motor driver, the controller can set the subdivision parameters of the stepping motor driver through software to adjust the precision of the stepping motor, for example: the stepping (distance) angle of the stepping motor is 3.6 degrees, the stepping motor driver can subdivide the stepping (distance) angle of the stepping motor, if 16 subdivisions are set, 3.6 degrees are equivalently divided into 16 parts, and the stepping angle of the final stepping motor under the control of the stepping driver is 0.225 degrees, so that the accuracy of what kind is needed can be adjusted only by subdividing the stepping motor driver through the controller (within the subdivision range supported by the stepping motor driver).
