Abstract
An exemplary system for measuring operational life of a computer mouse wheel is disclosed. The system includes a computer (10), a control card (11), a stepper motor servo controller (12), a stepper motor (13), a vertical servo axle (14), and a measurement platform (15). The vertical servo axle is structured and arranged for maintaining contacting with the computer mouse wheel (16). The computer is configured for sending an instruction for controlling operations of measuring the operational life of the computer mouse wheel, and includes a file module (20), a setting module (21), and a performing module (22). The control card is configured in the computer. A related method is also disclosed.
Claims8
A system for measuring operational life of a computer mouse wheel, the system comprising:
- a vertical servo axle being structured and arranged for maintaining contacting with the computer mouse wheel;
- a stepper motor connected with the vertical servo axle and controlling the vertical servo axle to do up-and-down movements which in response driving the computer mouse wheel to roll in opposite directions;
- a computer configured for setting a total running distance for the computer mouse wheel according to a standard operational life specification of the computer mouse wheel, setting running tasks for the computer mouse wheel according to the total running distance, and sending an instruction for controlling operations of measuring operational life of the computer mouse wheel following the running tasks;
- a stepper motor servo controller electrically connected between the computer and the stepper motor for sending an impulse control signal to control operation of the stepper motor;
- and
- a control card configured in the computer for controlling the stepper motor servo controller to send the impulse control signal to the stepper motor to drive the vertical servo axle and the computer mouse wheel to run following the running tasks.
A computer-based method for measuring operational life of a computer mouse wheel, the method comprising the steps of:
- initializing a communication port for a computer, in order that the computer communicates with a stepper motor servo controller via the communication port;
- setting a total running distance for the computer mouse wheel according to a standard operational life specification of the computer mouse wheel;
- setting running tasks for the computer mouse wheel according to the running measurement distance;
- sending an instruction for controlling operations of measuring operational life of the computer mouse wheel following the running tasks;
- receiving and processing the instruction from the computer, and sending a control signal to a stepper motor servo control;
- and
- sending an impulse control signal to a stepper motor to drive a vertical servo axle and the computer mouse wheel to run following the running tasks, in order to check whether the computer mouse wheel completes all the running tasks to meet the standard operational life specification of the computer mouse wheel.
