[0077] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0078] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0079] Figure 1 A flow chart of a method for quickly detecting the power generation performance of a magnetic backseat generator according to the present invention is shown.

[0080] S101, obtaining the power generation voltage and power generation time on the oscilloscope;

[0081] S102, determining the transmission voltage corresponding to the power generation time according to the power generation time;

[0082] S103, dividing the generated voltage by the transmitted voltage to obtain the power generation efficiency of the corresponding generator;

[0083] S104, based on the preset first time period, performing mean calculation on the power generation efficiency of the generator in the preset first time period to obtain the average power generation efficiency of the generator in the preset first time period;

[0084] S105: If the average power generation efficiency of the generator in the preset first time period is greater than the preset first threshold, the corresponding magnetic back seat generator is qualified.

[0085] According to an embodiment of the present invention, the step of obtaining the generating voltage and generating time on the oscilloscope specifically includes turning on the power button, clamping the armature and the magnetic core, connecting the circuit (oscilloscope), setting the circular iron core, setting the transmitting voltage, clicking the transmitting, electromagnetically accelerating the iron core, striking the magnetic core, and the magnetic core passing through the armature to generate an induced voltage which is displayed by the oscilloscope, marking the generating voltage and the transmitting voltage according to the generating time, determining the time of each generating voltage and the transmitting voltage, and then dividing the generating point voltage at the same generating time by the transmitting voltage to obtain the generating efficiency of the corresponding generator at the generating time; for example, if the preset first time period is 1 minute, then the average generating efficiency of the generator within 1 minute is greater than the preset first threshold value, and the corresponding magnetic rear seat generator is qualified; if the average generating efficiency of the generator within 1 minute is less than or equal to the preset first threshold value, the corresponding magnetic rear seat generator is unqualified.

[0086] According to an embodiment of the present invention, it also includes:

[0087] Calculate the difference of power generation efficiency at adjacent power generation times to obtain the power generation efficiency difference at adjacent power generation times;

[0088] If the power generation efficiency difference between adjacent power generation times is greater than a preset first threshold, the corresponding adjacent power generation times are marked to obtain the marked adjacent power generation times;

[0089] Extract the overload impact force of the generator at different power generation times;

[0090] According to the overload impact force of the generator at different power generation times, the overload impact force of the generator at the marked adjacent power generation times is obtained;

[0091] Calculate the difference of the overload impact force of the generator at adjacent marked power generation times to obtain a first difference of the overload impact force;

[0092] If the first difference of the overload impact force is less than or equal to the preset second threshold, the adjacent power generation time corresponding to the mark is set as abnormal power generation, and the abnormal power generation is accumulated once;

[0093] Obtaining a total number of abnormal power generation within a preset second time period;

[0094] If the total number of abnormal power generation within the preset second time period is greater than the preset first number threshold, the corresponding magnetic back seat generator is set to be unqualified.

[0095] It should be noted that when the first difference in overload impact force is greater than the preset second threshold, it means that the transmission voltage of the generator may be adjusted during the corresponding adjacent power generation time, and therefore the corresponding power generation is normal. If the power generation efficiency difference between adjacent power generation times is less than or equal to the preset first threshold, it means that the power generation efficiency difference between the corresponding adjacent power generation times is normal. When the power generation efficiency difference between adjacent power generation times is greater than the preset first threshold and the first difference in overload impact force between the corresponding adjacent power generation times is less than or equal to the preset second threshold, it means that abnormal power generation occurs once during the corresponding adjacent power generation time, and the abnormal power generation is accumulated through the preset second time period, and the total number of abnormal power generation is determined by the preset first number threshold.

[0096] According to an embodiment of the present invention, after extracting the overload impact force of the generator at different power generation times, the method further includes:

[0097] Extract the overload impact force at any power generation time;

[0098] Determine whether the overload impact force at any power generation time is greater than a preset third threshold value. If so, set the overload impact force corresponding to any power generation time as an abnormal overload impact force; if not, extract the overload impact force corresponding to the adjacent power generation time;

[0099] The overload impact force at any power generation time is calculated to be different from the overload impact force at the corresponding adjacent power generation time to obtain a second difference in the overload impact force;

[0100] If the second difference of the overload impact force is less than or equal to the preset fourth threshold value, the overload impact force corresponding to any power generation time is normal;

[0101] If the second difference of the overload impact force is greater than the preset fourth threshold value, the overload impact force corresponding to any power generation time is set as an abnormal overload impact force;

[0102] The power generation time and power generation voltage corresponding to the abnormal overload impact force are deleted.

[0103] It should be noted that after the generator adjusts the emission voltage, if the emission voltage is increased, the faster the speed of the corresponding electromagnetic acceleration core, the greater the corresponding overload impact force. There is an acceleration process before reaching stability. At that time, this acceleration will set a threshold, that is, the fourth threshold is preset to prevent damage to the generator due to excessive acceleration.

[0104] According to an embodiment of the present invention, it also includes:

[0105] Obtaining the total number of abnormal overload impact forces occurring within a preset third time period;

[0106] Determine whether the total number of abnormal overload impact forces occurring within a preset third time period is greater than a preset second number threshold, and if so, generate generator instability information;

[0107] Send generator instability information to the preset management terminal to shut down the generator in time.

[0108] It should be noted that, for example, if the third time period is preset to 20 seconds, the total number of abnormal overload impact forces occurring within 20 seconds is recorded, and a judgment is made based on the preset third number threshold to improve the stability of the generator.

[0109] According to an embodiment of the present invention, it also includes:

[0110] Calculating the difference between the emission voltages at adjacent power generation times to obtain a first emission voltage difference;

[0111] If the first transmission voltage difference is greater than the preset first voltage difference threshold, the transmission voltage adjustment information is obtained, and the previous power generation time corresponding to the adjacent power generation time is recorded and set as the transmission voltage adjustment time;

[0112] Taking the time of adjusting the transmission voltage as the time node, extracting the power generation voltage within a preset fourth time period, and calculating the power generation voltage difference between adjacent power generation times within the preset fourth time period;

[0113] If the power generation voltage difference between adjacent power generation times is less than the preset second voltage difference threshold, stable power generation is recorded once;

[0114] Extracting the total value of stable power generation within a preset fifth time period;

[0115] If the total number of stable power generation times within the preset fifth time period is greater than the preset third number threshold, the start time of the preset fifth time period is extracted, and the corresponding power generation time is set as the stable power generation time;

[0116] Subtract the time of adjusting the transmitting voltage from the stable power generation time to obtain the stable power generation time of the generator;

[0117] Dividing the first transmission voltage difference by the stable power generation time of the generator to obtain the stable power generation efficiency of the generator;

[0118] If the power generation stability efficiency of the generator is greater than the preset power generation stability efficiency threshold, the corresponding generator is normal;

[0119] If the power generation stability efficiency of the generator is less than or equal to the preset power generation stability efficiency threshold, the corresponding generator is marked as unstable once;

[0120] Obtaining a total number of times that the generator is marked as unstable within a preset sixth time period;

[0121] When the total number of times that the generator is marked as unstable within the preset sixth time period is greater than the preset fourth number threshold, the corresponding generator is set as unqualified.

[0122] It should be noted that the first transmitting voltage difference threshold is judged by setting the first voltage difference threshold, and the power generation stability efficiency of the generator from the time of adjusting the transmitting voltage to the time when the power generation voltage is stable is found, and then the preset power generation stability efficiency threshold is used to determine whether the power generation of the generator is stable. Finally, the preset sixth time period is used as the deadline to determine the number of stable or unstable times of the generator, and accurately determine whether the corresponding generator is stable in power generation.

[0123] According to an embodiment of the present invention, it also includes:

[0124] Obtaining display characteristics and corresponding display characteristic values ​​of the generator when generating electricity;

[0125] Normalizing the display characteristic value according to a preset standard display characteristic range to obtain a normalized display characteristic value;

[0126] Multiply the normalized display feature value by the influence weight coefficient of the corresponding display feature to obtain the influence value of the corresponding display feature;

[0127] The influence values ​​of different display characteristics are accumulated to obtain the influence value of the corresponding generator when generating electricity;

[0128] Determine whether the impact value of the generator during power generation is greater than a preset impact threshold. If so, trigger a power generation warning message; if not, collect the corresponding power generation voltage and construct a power generation voltage set;

[0129] Extracting the maximum power generation voltage from the power generation voltage concentration and setting it as the optimal power generation voltage;

[0130] The optimal power generation voltage is sent to the preset management terminal for display.

[0131] It should be noted that the display characteristics of the generator when generating electricity, such as noise, vibration amplitude, etc., are counted. If the display characteristic is noise, the corresponding display characteristic value is the noise amount. The maximum value in the standard display characteristic range is subtracted from the corresponding display characteristic value to obtain a first value. The maximum value in the standard display characteristic range is subtracted from the minimum value to obtain a second value. The first value is divided by the second value to obtain a normalized display characteristic value of the corresponding display characteristic. The preset impact threshold is used as a limiting limit to exclude the power generation voltage greater than the preset impact threshold, and the maximum power generation voltage less than or equal to the preset impact threshold is found and set as the optimal power generation voltage, which is displayed on the preset management end to improve the power generation stability of the generator and reduce the generator loss.

[0132] According to an embodiment of the present invention, it also includes: if the display characteristic value is greater than a preset standard display characteristic range, triggering a power generation warning message.

[0133] It should be noted that, when the display characteristic value is smaller than the preset standard display characteristic range, the corresponding display characteristic value is set to the minimum value in the standard display characteristic range.
