Description

Technical Field

[0001] This application belongs to the field of optical detection technology, specifically relating to an automatic light-emitting device, an operating system, and its usage method. Background Technology

[0002] Lasers, compared to ordinary light sources, possess monochromaticity, directionality, and high brightness. Therefore, laser beams have highly concentrated energy, allowing them to travel long distances without attenuation, and are widely used in scientific research, medicine, and industrial processing. During laser use, baffles are often used to block the laser beam. When the laser power is high, there is a risk of burns or scalds to the human body. Even when looking directly at the point where the light is blocked by the baffle, the diffused light entering the eye is still quite strong, posing a risk of decreased vision.

[0003] Currently available automatic light-blocking devices mainly use slide rails or other electrically operated telescopic devices to control the movement of the baffle. However, devices that allow the baffle to move back and forth along the slide rail, or light-blocking devices that include a baffle, rocker arm, telescopic unit, and power-on unit, all require a large amount of space. Furthermore, the method of moving the baffle back and forth along the slide rail or having the telescopic unit drive the rocker arm to swing back and forth to move the baffle is inefficient. In addition, current light-blocking devices have limited functionality, only able to simply block and release a single laser beam. Summary of the Invention

[0004] The purpose of this application is to provide an automatic light-emitting device and system to solve the problems mentioned in the background art.

[0005] The technical solution to achieve the purpose of this application is as follows:

[0016] The serial port connection module is used to establish a communication connection between the motion control card and the host computer;

[0017] The fine-tuning module fine-tunes the angle of the stepper motor, causing the baffle to rotate so that the laser beam is incident perpendicularly onto the baffle;

[0018] The single-channel blocking / releasing module rotates a stepper motor 90° to perform light blocking or light releasing operations;

[0019] The parameter setting status query module allows for setting and querying stepper motor parameters;

[0020] Complex function modules are used to set up and store different tasks, and the set tasks will be executed automatically after operation.

[0021] Optionally, the fine-tuning module and the single-channel stop module can set the stepper motor rotation angle by inputting the number of pulses;

[0022] When the single-channel baffle module is set to 800 pulses, the stepper motor rotates 90° clockwise, causing the baffle to emit light; when the pulse count is set to -800, the stepper motor rotates 90° counterclockwise, causing the baffle to block the light.

[0023] Optionally, the fine-tuning module, single-channel stop module, and parameter setting status query module can operate the corresponding stepper motor by inputting the stepper motor number;

[0024] Enter 0 when operating all stepper motors simultaneously; enter the corresponding stepper motor number when operating each stepper motor individually.

[0025] Optionally, there is a parameter setting status query module, which allows setting and querying parameters including the stepper motor's speed, acceleration, maximum speed, and deceleration.

[0026] Optionally, the complex functional module can store three different tasks;

[0027] Complex function modules are also used to display task progress.

[0028] The third aspect of this application provides a method for using an automatic transmission light-emitting operating system, including the following steps:

[0082] The following detailed explanation, using a specific example, illustrates the usage method of an automatic light-emitting operating system provided in this application.

[0083] The automatic light emission device has four light sources, corresponding to four stepper motors 3 and baffles 2. The motion control card used can be a four-axis control card.

[0084] 6. Select stepper motors 3, numbered sequentially from 1 to 4.

[0086] Enter the USB serial port card number connecting the host computer 7 and the motion control card 6 into the serial port connection module, and click the "Open Serial Port Card" button. A dialog box will pop up indicating whether the serial port card was opened successfully or failed.

[0087] If it fails, check the USB interface and re-enter the correct serial port card number.

[0088] In the parameter setting status query module, enter stepper motor number 3 as 1, and enter the speed, acceleration and other parameters of the first stepper motor; during operation, switch to parameter acquisition to obtain the above parameters of the first stepper motor.

[0089] When the stepper motor 3 is input as number 1 in the single-channel baffle module and the pulse count is 800, the first stepper motor will rotate 90 degrees clockwise, causing the baffle 2 to emit light; when the pulse count is set to -800, the first stepper motor will rotate 90 degrees counterclockwise, causing the baffle 2 to block the light.

[0090] If the operation is mistakenly repeated, it will not be executed; instead, a dialog box will pop up indicating that the action has been placed or blocked.

[0091] In the fine-tuning module, input stepper motor number 3 as 1 and input pulse number -790 to fine-tune the angle of the first stepper motor.

[0092] Enter the stepper motor numbers 2 to 4 in the fine-tuning module, single-channel stop-release module, and parameter setting status query module in sequence, and repeat the above operations to complete the automatic stop-release of all four channels.

[0093] For directional operation, three different tasks were set and stored in the complex function module during the above process. Clicking the button can automatically execute the corresponding task. After clicking the button on the left to start executing the task, the task progress will be displayed on the right.

[0094] The Task 1 button stores the following operation tasks: First, control the second stepper motor to emit light for 60 seconds; then, control the second stepper motor to block light for 10 seconds; next, emit light completely for 120 seconds; finally, control the second stepper motor to block light for 10 seconds, and then emit light again. This cycle repeats 5 times.

[0095] The Task 2 button stores the following operation tasks: First, perform a full release operation for 120 seconds; then perform a full block operation for 120 seconds, and then perform a full release operation again, repeating this cycle 5 times in total.

[0096] The Task 3 button stores the following operation tasks: First, illuminate the second to fourth stepper motors for 120 seconds; then, perform a full-speed operation for 2 seconds; next, illuminate the first to third stepper motors for 120 seconds; finally, perform a full-speed operation.
