[0047] See also Figure 1 The embodiment of the present invention provides a camera driving function automatic test system, including a simulation test device 1 and a signal acquisition device 2. The simulation test device 1 is connected to a camera lens driving circuit interface 3, and the signal acquisition device 2 is connected to the simulation test device 1. The simulation test device 1 includes a simulation focusing device 11 and a simulation aperture adjustment device 12. The simulation focusing device 11 and the simulation aperture adjustment device 12 perform mechanical actions according to the driving electrical signal of the camera lens driving circuit interface 3. The signal acquisition device 2 acquires the square wave electrical signal generated by the mechanical actions of the simulation focusing device 11 and the simulation aperture adjustment device 12, so as to determine whether the camera lens driving circuit function is normal.

[0048] Specifically, the simulated focusing device 11 and the simulated aperture adjustment device 12 respectively simulate the focusing and aperture adjustment functions of the camera lens. When initiating the camera lens drive circuit function test, the main board of the camera can send a driving electrical signal to the simulated focusing device 11 and the simulated aperture adjustment device 12 through the camera lens drive circuit interface 3 according to the set rules (which can be pre-set) to drive the simulated focusing device 11 and the simulated aperture adjustment device 12 to perform corresponding mechanical actions, thereby generating corresponding square wave electrical signals, and the signal acquisition device 2 acquires the square wave electrical signals for processing and determines whether the camera lens drive circuit function is normal.

[0049] It should be noted that the signal acquisition device 2, such as a data acquisition card (DAQ) or a microcontroller (MCU), etc., can be integrated on the camera under test or exist independently of the camera under test.

[0050] The present invention utilizes the simulated focusing device 11 and the simulated aperture adjustment device 12 to simulate the focusing and aperture adjustment of a physical lens, thereby determining whether the camera lens driving circuit functions normally according to the simulated situation. No physical lens is required, and no manual operation is required, which greatly improves the test efficiency and avoids the problem of misdetection and missed detection in manual testing.

[0051] See also Figures 2 to 3 The simulated focusing device 11 and the simulated aperture adjustment device 12 both include a motor 111, a transmission mechanism 112, a light shielding plate 113 and a photoelectric sensor 114. The transmission mechanism 112 is connected to the motor 111, and the light shielding plate 113 is connected to the transmission mechanism 112. Under the transmission action of the transmission mechanism 112, the light shielding plate 113 rotates to periodically shield the photoelectric sensor 114.

[0052] The motor 111 may be a stepper motor for precise control. The transmission mechanism 112 may be a gear transmission, a belt transmission, a screw transmission, or a rack and pinion transmission, etc. In this embodiment, a gear transmission is adopted, and a gear set composed of a plurality of gears is used for precise control. The photoelectric sensor 114 may be a beam type photoelectric sensor 114, a diffuse reflection type photoelectric sensor 114, or a laser displacement sensor, etc.

[0053] After the motor 111 in the analog focusing device 11 receives the focusing signal from the camera lens driving circuit interface 3, it drives the light shielding plate 113 to rotate through the transmission mechanism 112, thereby periodically shielding the photoelectric sensor 114 and generating a series of square wave electrical signals. Similarly, after the motor 111 in the analog aperture adjustment device 12 receives the aperture adjustment signal, it also drives the light shielding plate 113 to rotate through the transmission mechanism 112 and generates square wave electrical signals. The signal acquisition device 2 collects these square wave electrical signals and transmits them to the processing unit for further analysis and processing.

[0054] In one embodiment, the light shielding plate 113 is a plate-like structure, including a connecting plate portion, a shielding plate portion, and a connecting transition plate portion. The connecting plate portion is in a circular ring shape and is connected to the transmission mechanism 112. The shielding plate portion is in a semicircular ring shape. One side of the connecting transition plate portion is connected to the edge of one side of the connecting plate portion, and the other side of the connecting transition plate portion is connected to the center of the inner ring of the shielding plate portion. The photoelectric sensor 114 is arranged below the shielding plate portion. When the shielding plate portion rotates to the position where the photoelectric sensor 114 is located, a part of the shielding plate portion can be located between the transmitter and the receiver of the photoelectric sensor 114, thereby shielding the photoelectric sensor 114. When working, the light shielding plate 113 rotates along the Z axis of the spatial rectangular coordinate system under the action of the transmission mechanism 112 to periodically shield the photoelectric sensor 114, thereby generating a standard square wave electrical signal.

[0055] See also Figure 4 The embodiment of the present invention further provides a camera driving function automatic testing method, which is applied to the above-mentioned camera driving function automatic testing system, and the method includes the following steps: S10-S30.

[0056] S10 , collecting square wave electrical signals generated when the photoelectric sensor 114 is periodically blocked by the light shielding sheet 113 .

[0057] By controlling the motor 111 to rotate, the motor 111 drives the light shielding plate 113 to periodically block or not block the light of the photoelectric sensor 114, so that a periodic square wave can appear in the photoelectric sensor 114. Through the detection of the photoelectric sensor 114, the movement state of the light shielding plate 113 can be obtained in real time, ensuring that the obtained square wave electrical signal has clear periodicity and accuracy.

[0058] In order to save testing time, the two motors 111 of the simulated focusing device 11 and the simulated aperture adjustment device 12 can be controlled to rotate synchronously, so that the square wave electrical signals during focusing and aperture adjustment can be obtained synchronously.

[0059] S20 , processing the square wave electrical signal to obtain rotation data of the motor 111 .

[0060] In one embodiment, step S20 specifically includes the following steps: S201 - S203 .

[0061] S201, calculating the time difference between two adjacent square wave edges in the square wave electrical signal.

[0062] Receive the square wave electrical signal, identify the time points of the adjacent rising or falling edges, and calculate the time difference between these time points. By accurately calculating the time difference between the adjacent square wave edges, the time information of the motor 111 passing a certain angle can be obtained, laying the foundation for further calculating the rotation time and speed of the motor 111.

[0063] S202, calculating the time taken by the motor 111 to rotate one circle according to the time difference between two adjacent square wave edges.

[0064] The time required for the motor 111 to rotate one circle is calculated by accumulating the angle of rotation of the motor 111 corresponding to the known square wave edge. Specifically, each square wave period corresponds to a specific rotation angle θ of the motor 111. According to the size of θ, the number of square wave periods n required for one circle (360 degrees) is calculated, and then the total time T for the motor 111 to rotate one circle is obtained by accumulating the corresponding time difference ΔT. By calculating the total time for the motor 111 to rotate one circle, the rotation period of the motor 111 can be accurately obtained, which provides an accurate basis for the subsequent calculation of the rotation speed.

[0065] S203 , calculating the rotation speed of the motor 111 according to the time taken for the motor 111 to rotate one circle.

[0066] By accurately calculating the rotation speed of the motor 111 , the operating state of the motor 111 can be obtained in real time.

[0067] S30 , driving the camera lens driving circuit according to the rotation data of the motor 111 to determine whether the function is normal.

[0068] In one embodiment, step S30 specifically includes the following steps: S301 - S303 .

[0069] S301 , comparing the rotation data of the motor 111 with the reference data.

[0070] The reference data may be a rotation speed range or rotation time range of the motor 111 under normal working conditions obtained through experiments. For example, the preset reference range of the motor 111 speed is 1000RPM±50RPM. The actual rotation data is numerically compared with the reference data, and the difference Δ between the actual rotation data and the reference data is calculated, Δ=|actual rotation data-reference data|.

[0071] By comparing the actual rotation data of the motor 111 with the reference data, it is possible to quickly identify whether the motor 111 is running in the expected working state, providing a reliable basis for judging the functional state of the camera lens driving circuit interface 3 .

[0072] S302: If the comparison results are consistent or within the set threshold range, it is determined that the camera lens driving circuit functions normally; otherwise, it is determined that the function is abnormal.

[0073] Set an allowable error range according to actual needs, for example, set the threshold range to ±5RPM.

[0074] Decision logic: If the difference Δ≤threshold, the drive circuit is considered to be functioning normally; otherwise, it is considered that the drive circuit may be faulty and an alarm or further detection is triggered.

[0075] By setting a reasonable threshold range, small errors and noise can be effectively filtered out to ensure the accuracy and reliability of the judgment results. At the same time, abnormal circuits can be alarmed and processed in time to improve the stability and safety of the system.
