Description

Technical Field

[0001] This invention relates to an electric probe multi-point illuminance meter and its measurement method. Background Technology

[0002] In existing illuminance measurement technologies, multi-point illuminance meters are widely used to measure the illuminance and uniformity of flashlights. Multi-point illuminance meters typically consist of multiple probes that are magnetically attached to the test panel. Different mobile phone models have different probe placement positions, requiring manual adjustment of the probe positions. This operation is both cumbersome and inaccurate, affecting the accuracy of the measurement results.

[0003] shortcoming:

[0004] 1. Instability: Due to the instability of manually adjusting the probe position, the probe may shift or sway during the measurement process, thus affecting the stability and consistency of the illuminance measurement results.

[0005] 2. Difficult to adjust: The placement of the probe varies greatly between different models of mobile phones, requiring users to have certain professional knowledge and experience to accurately adjust the position of the probe, which is quite difficult for non-professionals.

[0006] 3. Human error: Manually adjusting the probe position is susceptible to human error. If the operation is not careful or the hand is not positioned accurately, the probe position may be offset, which will affect the accuracy of the measurement results.

[0007] 4. Labor costs: Manually adjusting the probe position requires manpower, especially in large-scale or frequent measurement tasks, which increases labor costs and workload. Summary of the Invention

It analyzes and provides feedback on illuminance distribution in real time, offering accurate measurement results.

[0062] Once each probe is adjusted to its designated position, the current position information is fed back to the computer terminal to ensure that the probe has been accurately adjusted. This ensures the accuracy and reliability of the measurement data.

[0063] In one embodiment of the electric probe multi-point illuminance meter of the present invention, a third motor is also provided on each slide rail 7. The third motor is connected to the controller, and the computer terminal controls the third motor through the controller to adjust the rotation angle of each slide rail 7 around the rotation axis.

[0068] The above describes the connection relationships of the various components of the lux meter in its static state. Through these connections, the probe is fixed on the main slide rail, and precise position adjustment is achieved through the motor and control system. This connection configuration ensures the stability and accuracy of the lux meter during operation.

[0069] The following is a description of the usage process of the device of the present invention:

[0070] Step 1: Place the object to be measured on the object clamp 1, adjust the object clamp 1 up and down so that the object to be measured and the middle probe are on the same horizontal plane, adjust the elevation angle of the object clamp 1 so that the measured surface is parallel to the surface composed of 9 illuminance meter probes, adjust the clamp position adjustment device 2 left and right to align the center of the object to the first illuminance meter probe at the intersection point; adjust the object support bracket 3 back and forth to fix the plane of the object to be measured and the illuminance meter probe at a preset distance.

[0071] Step 2: The computer terminal outputs instructions to the controller 5 via wired or wireless means. The instructions include: testing the FOV size and aspect ratio, etc. The user can also edit the position of each probe individually. After receiving the instructions, the controller 5 converts them into position information and transmits the position information to the first drive motor of each illuminance meter probe and the third motor of the two slide rails 7 via wired or wireless means.

[0072] Here, the angle between the two slide rails can be adjusted by the third motor. After receiving the position information, the first drive motor drives the illuminance meter probe 9 to move to the position of the slide rail 7 through the drive wheel 11 and the auxiliary fixed wheel 12.

[0073] The third step is to control the illuminance meter probe to turn on the light-sensing mode to test the illuminance; the controller 5 transmits the tested illuminance to the computer terminal via wired or wireless means.

[0074] In this invention, nine probes are moved by motors on two intersecting inclined slide rails, and the position of the probes is precisely adjusted and controlled by a computer control system.

[0075] Each probe is equipped with a first drive motor 10, drive wheel 11, and auxiliary fixing wheel 12. It is connected to a computer terminal via wired or wireless means to receive instructions and precisely adjust the placement of the probe, and return data to the computer to confirm that it has been adjusted in place.

[0076] A rigid connection is used to fix the slide rail to the support column, ensuring the stability and accuracy of the probe during movement and adjustment.

[0077] Each illuminance meter probe is equipped with a first drive motor, and the probe position is adjusted and placed through precise control of the first drive motor.

[0078] The computer terminal can achieve precise control and adjustment of the probe position through the software interface.

[0079] The illuminance meter probe can be equipped with a high-precision sensor to detect illuminance and uniformity data in real time and transmit the data to a computer terminal for processing and analysis.

[0080] A dedicated connection circuit can be used to connect the probe to the computer terminal via wired or wireless means to ensure stable and reliable data transmission.

[0081] The computer control system employs advanced control algorithms to precisely adjust the probe position based on input measurement parameters and feedback data.
