[0045] The present invention uses a flow chart to illustrate the operations performed by the system according to an embodiment of the present invention. It should be understood that the preceding or following operations are not necessarily performed precisely in order. Instead, various steps may be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0046] Photovoltaic tracking controller is an electronic product designed and used by combining a variety of electronic components. It is mainly used for tracking solar radiation outdoors and controlling the photovoltaic tracking bracket to follow the sun. The typical operation of photovoltaic tracking controller is intermittent operation, that is, running for a period of time and then stopping for a period of time. The typical application scenario is that the outdoor working environment has a large temperature span, the humidity environment is uncontrolled, and some electronic devices run intermittently. Therefore, the life of its electronic devices is mainly affected by the external temperature and humidity environment and operating characteristics.

[0047] Accurately setting the operating mode of the tracking controller during the test is an important parameter for evaluating the accuracy of the test. For example, in an accelerated life test, the setting of the operating mode of the tracking controller is an important parameter for evaluating the accuracy of the accelerated life test corresponding to the actual application life of the product. Accelerated life testing is a method for evaluating the life of electronic products. It significantly shortens the test cycle by increasing the test stress and setting a reasonable operating mode.

[0048] The method for setting the operating mode of a photovoltaic tracking controller for testing provided in an embodiment of the present invention mainly includes: analysis of the target application scenario, setting the operating state during the test, and determining the photovoltaic tracking bracket motor reducer current simulation device. Among them, the analysis of the target application scenario refers to the operating status of the photovoltaic tracking controller under actual operating conditions. The setting of the operating state during the test refers to designing the operating state of the simulated operation during the test based on the analysis of the target application scenario. The photovoltaic tracking bracket motor reducer current simulation device refers to a device that simulates the photovoltaic tracking bracket motor reducer current based on the photovoltaic tracking bracket motor reducer current, using a programmable electronic load or the like. The present invention can accurately design the operating conditions when conducting a photovoltaic tracking controller test, ensure that the actual operating conditions are restored in the test link, and improve the accuracy of the test results.

[0049] Figure 1 FIG. 1 is a flow chart of a method for setting an operating mode of a photovoltaic tracking controller for testing provided by an embodiment of the present invention. Figure 1 As shown in the figure, the method for setting the operating mode of the experimental photovoltaic tracking controller includes the following:

[0050] Step 101: Acquire actual operation information of a photovoltaic tracking controller in a target scene.

[0051] The operation status of the photovoltaic tracking controller in different application scenarios may be different, such as the tracking range and tracking time may vary according to different geographical locations. Therefore, it is necessary to analyze the actual operation information of the photovoltaic tracking controller in the target scene. In some embodiments, the actual operation information of the photovoltaic tracking controller in the target scene obtained includes the tracking range of the photovoltaic tracking controller, the total operation time to achieve the tracking range, and the speed of the motor reducer.

[0052] When the photovoltaic tracking controller is running, the current will change due to wind resistance and the change of the tracking bracket torque. Relevant operating data needs to be obtained for analysis, and the speed of different motor reducers may also be different. For example, the maximum tracking angle of the photovoltaic tracking controller is 60° east-west, and the tracking rotation is 240° every day, and the east-west direction runs 120° each. When the photovoltaic tracking controller is running, the maximum current is 6A, the average current is 4A, and the minimum current is 1A. The speed of a motor reducer is about 1 degree / 15s.

[0053] Step 102, determining the actual operation cycle, actual operation time and actual load current according to the actual operation information, wherein the actual operation cycle is the time for the photovoltaic tracking controller to control the photovoltaic tracking bracket to rotate once to track the target angle, the actual operation time is the time required for the motor reducer of the photovoltaic tracking bracket to operate the target angle, and the actual load current includes at least the rated current of the motor reducer. In the embodiment of the present invention, the photovoltaic tracking controller controls the photovoltaic tracking bracket to track a target angle of 1 degree each time it rotates. It should be understood that in some other embodiments, the photovoltaic tracking controller controls the photovoltaic tracking bracket to track a target angle of 1 degree each time it rotates.

[0054] In some embodiments, the actual operation cycle can be determined according to the tracking range of the photovoltaic tracking controller, the total operation time to achieve the tracking range and the target angle, and the actual operation time can be determined according to the speed of the motor reducer. Specifically, assuming that the tracking range of the photovoltaic tracking controller is α (degrees) and the operation time is t (s), the actual operation cycle total time T1 (s) of the operation target angle β (degrees, such as 1°) can be obtained, that is,

[0055]

[0056] For example, in the normal tracking stage, it runs from 60° east to 0° horizontally, and then from 0° horizontally to 60° west, which takes about 6 to 8 hours in total. It is related to the sunshine duration of each day. It needs to track 15° to 20° per hour, and rotate once every 3 to 4 minutes, with an angle of 1° each time. In the reverse tracking stage, it runs from 0° horizontally to 60° east or from 60° west to 0° horizontally. It takes about 4 to 6 hours in total. It is related to the sunshine duration of each day. It needs to track 20° to 30° per hour, and rotate once every 2 to 3 minutes, with an angle of 1° each time. According to formula (1), in the normal tracking stage of running from 60° east to 60° west, the actual operation period of running 1° is T1=(6-8)*60*60 / 120=180-240(s). In the reverse tracking stage, the actual operation period of running 1° is T1=(4~6)*60*60 / 120=120~180(s).

[0057] Assuming that the rated operating speed of the motor reducer is n (r / min), the actual operating time T2 (s) required to rotate the target angle β to 1° can be obtained from the rated speed of the motor reducer, that is,

[0058]

[0059] For example, if the rated speed of the motor reducer is 0.0111 rpm, then according to formula (2), the actual running time for running 1° is T2=1 / (6*0.0111)=15 (s).

[0060] It should be noted that the actual operation information obtained in step 101 may also directly include information such as the actual operation cycle, the actual operation time and the actual load current, and then there is no need to perform calculation in step 102.

[0061] Step 103: Determine the simulated operation time, simulated intermittent time and simulated operation current of the photovoltaic tracking controller according to the actual operation cycle, the actual operation time and the actual load current.

[0062] In general, the maximum operating current of the motor reducer will correspond to its load conditions. According to the actual application conditions, its operating current is basically close to the rated current of the motor reducer. Therefore, the simulated operating current of the photovoltaic tracking controller can use the rated current of the motor reducer. For example, the rated current of a motor reducer is 4A, which is in line with the load conditions in actual applications.

[0063] In some embodiments, the operating time percentage N may be determined according to the actual operating cycle and the actual operating time. or Then, the simulated running time and simulated intermittent time of the photovoltaic tracking controller are determined according to the actual running cycle and the running time ratio. For example, according to the running condition described in step 102, it runs once every 3 to 4 minutes or once every 2 to 3 minutes, and takes the middle value, and runs once every 3 minutes. Then, the actual running time of each 1° operation is 15s, which accounts for about 1 / 12 of the 3-minute interval period of each operation, that is, 15s / (3*60)s=1 / 12. According to this ratio, the simulated running time of the photovoltaic tracking controller is 15s, and the simulated intermittent time is 165s.

[0064] In some other embodiments, the simulated running time can be directly determined as the actual running time, and the simulated intermittent time can be determined as the difference between the actual running cycle and the actual running time. For example, according to the running condition described in step 102, the running time is once every 3 to 4 minutes or once every 2 to 3 minutes, and the middle value is taken, and the running time is once every 3 minutes. The actual running time of each running of 1° is 15 seconds, then the simulated running time can be directly determined to be 15 seconds, and the simulated intermittent time is 180-15=165 seconds.

[0065] Optionally, in order to set the simulation operation mode more carefully or accurately, the average mode may not be used, and the operation cycle may be subdivided and set according to the normal tracking stage and the reverse tracking stage, that is, different operation cycles are set according to the actual operation mode. For example, the actual operation cycle of the photovoltaic tracking controller can be divided into a first sub-cycle (corresponding to the normal tracking stage) and a second sub-cycle (corresponding to the reverse tracking stage). Accordingly, the simulation operation time includes a first sub-operation time and a second sub-operation time, and the simulation interval time includes a first sub-interval time and a second sub-interval time, wherein the first sub-operation time and the first sub-interval time are determined according to the first sub-cycle and the actual operation time, and the second sub-operation time and the second sub-interval time are determined according to the second sub-cycle and the actual operation time. For example, in the actual operation cycle, the first sub-cycle of the normal tracking stage is 2 minutes, the second sub-cycle of the reverse tracking stage is 4 minutes, and the actual operation time is 15 seconds, then it can be determined that the first sub-operation time is 15 seconds, the first sub-interval time is 105 seconds, the second sub-operation time is 15 seconds, and the second sub-interval time is 225 seconds.

[0066] It should be understood that the above is only an exemplary method for determining the simulated operating time, simulated intermittent time and simulated operating current of a photovoltaic tracking controller. However, changes in the tracking angle range and changes in the motor reducer speed affect the parameter settings of the operating cycle, operating time length and proportion in the simulation scheme, as well as the determination of the load current. That is, the actual operating time in the operating cycle and its proportion of the total cycle can be reasonably determined by using the tracking range, motor reducer speed, and operating time of each stage, so as to set the operating mode of the photovoltaic tracking controller under test in the test.

[0067] Step 104: setting the operation mode of the photovoltaic tracking controller according to the simulated operation time, the simulated intermittent time and the simulated operation current.

[0068] For example, the operation mode of the photovoltaic tracking controller can be set to run for 15s and stop for 165s, which is closer to the operating and stopping time ratio working conditions of the electronic devices of the actual product. Optionally, if the actual operation cycle of the photovoltaic tracking controller is divided into a first sub-cycle (corresponding to the normal tracking stage) and a second sub-cycle (corresponding to the reverse tracking stage), the photovoltaic tracking controller is set to alternately operate according to the first sub-operation mode and the second sub-operation mode accordingly. The first sub-operation mode is set according to the first sub-operation time and the first sub-interval time, and the second sub-operation mode is set according to the second sub-operation time and the second sub-interval time. For example, the first sub-cycle of the normal tracking stage in the actual operation cycle is 2min, the second sub-cycle of the reverse tracking stage is 4min, and the actual operation time is 15s. Then, it can be determined that the first sub-operation mode is to run for 15s and stop for 105s, and the second sub-operation mode is to run for 15s and stop for 225s. It should be understood that the actual operation cycle can also be divided into more sub-cycles, and more sub-operation modes are set accordingly.

[0069] Furthermore, a suitable current simulation device may be used according to the determined simulated operating current, such as a programmable electronic load for load simulation. In some embodiments, the motor reducer has different driving directions, and an H-bridge circuit is generally used for drive adjustment, while the electronic load has the characteristics of a unidirectional load. To ensure balanced use of the left and right bridge arms, a non-polarity load may be used for load simulation instead of the electronic load, such as a pure resistor or a motor transmission system with a damping device.

[0071] It should be noted that the above-mentioned test photovoltaic tracking controller operation mode setting device can be a host computer connected to the photovoltaic tracking controller.
