[0050] Compared with the prior art, the present invention has the following beneficial effects: During the charging process of the traditional tower crane battery, the charging abnormal condition threshold is often fixed and cannot adapt to the battery changes under different environments and working conditions. However, the present invention dynamically adjusts the charging abnormal condition threshold by real-time monitoring the temperature and voltage change rate of the battery, making the charging process more flexible and safe. This can not only prevent the battery from being damaged due to overcharging or over-discharging, but also extend the service life of the battery. When the temperature or voltage of the battery monitored in real time exceeds the dynamically adjusted abnormal condition threshold, the charging will be immediately terminated and a warning will be issued to prevent further damage to the battery. This intelligent warning and intervention mechanism can greatly reduce the need for manual intervention, improving the automation level and safety. In the case where the charging abnormal condition threshold does not need to be adjusted, the cycle duration is adaptively adjusted according to the temperature and voltage change rate of the battery. This adaptive adjustment mechanism can make the charging process more in line with the actual needs of the battery, improving the charging efficiency and the performance of the battery. In summary, the present invention improves the safety, reliability and stability of the charging process of the tower crane battery, extends the service life of the battery, reduces the maintenance cost, and has broad application prospects and market potential by dynamically adjusting the charging abnormal condition threshold, intelligent warning and intervention, and adaptive adjustment of the charging cycle.

It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0055] Refer to Figure 1 As shown, this embodiment provides a method for protecting the charging of a tower crane battery, and the method includes:

[0056] S101: Obtain the initial battery state data of the tower crane battery, and determine whether to charge the tower crane battery according to the initial battery state data.

[0057] S102: When it is determined to charge the tower crane battery, preset the initial charging conditions, charge the tower crane battery based on the initial charging conditions, and obtain the real-time battery state data of the tower crane battery during the charging process.

[0058] Wherein, the initial charging conditions include: initial charging current and initial charging voltage.

[0059] S103: Preset the charging end condition threshold and the charging abnormal condition threshold, and determine whether to end the charging of the tower crane battery according to the relationship between the real-time battery state data and the charging end condition threshold.

[0060] S104: When it is determined not to end the charging of the tower crane battery, preset the initial adjustment cycle duration, process the real-time battery state data within the initial adjustment cycle duration to obtain the battery state cycle processing data, and determine whether to adjust the charging abnormal condition threshold according to the battery state cycle processing data.

[0061] S105: When it is determined to adjust the charging abnormal condition threshold, use the adjusted charging abnormal condition threshold as the charging abnormal condition cycle threshold. When the real-time battery state data is within the charging abnormal condition real-time threshold range, directly end the charging of the tower crane battery and give an alarm.

[0062] S106: When it is determined not to adjust the charging abnormal condition threshold, adjust the initial adjustment cycle duration according to the battery state cycle processing data to obtain the real-time cycle duration, and process the real-time battery state data within the real-time cycle duration.

[0063] It can be understood that in this embodiment, by obtaining the initial battery state data of the tower crane battery and determining whether to charge based on this data, the pertinence and rationality of the charging process are ensured, unnecessary charging operations are avoided, and the service life of the battery is extended. During the charging process, not only the initial charging conditions are preset, but also the charging state data of the tower crane battery is obtained in real time, which provides accurate and timely data support for subsequent charging control and abnormal warning. By setting the charging end condition threshold, it can be ensured that the battery stops charging in time after reaching the optimal state, preventing damage to the battery caused by overcharging. In this embodiment, the charging abnormal condition threshold is also set and dynamically adjusted during the charging process. This dynamic adjustment mechanism enables the system to flexibly respond to various abnormal situations according to the actual situation, improving the stability and safety of the system. When the real-time battery state data exceeds the charging abnormal condition cycle threshold, the system will immediately stop charging and give an alarm, thus effectively avoiding possible dangers and losses. Finally, by adjusting the initial cycle duration to obtain the real-time cycle duration and processing the real-time battery state data within the real-time cycle duration, this method further improves the fineness and accuracy of charging control. This refined charging control strategy can better meet the charging requirements of the tower crane battery and ensure its operation in the optimal state.

[0064] In some embodiments of the present application, the initial battery state data includes: initial battery power, initial battery voltage, and initial battery temperature.

[0065] In some embodiments of the present application, when obtaining the initial battery state data of the tower crane battery and determining whether to charge the tower crane battery according to the initial battery state data, it includes:

[0066] Preset the minimum power threshold and the minimum voltage threshold in advance;

[0067] When the initial battery power is less than the minimum power threshold or the initial battery voltage is less than the minimum voltage threshold, it is determined to charge the tower crane battery;

[0068] When the initial battery power is greater than or equal to the minimum power threshold or the initial battery voltage is greater than or equal to the minimum voltage threshold, it is determined not to charge the tower crane battery.

[0069] It can be understood that in this embodiment, by setting the minimum power threshold and the minimum voltage threshold, charging can be carried out only when the power or voltage of the tower crane battery truly needs to be charged, avoiding unnecessary energy waste. Frequent or improper charging will damage the battery and shorten its service life. This embodiment helps to extend the service life of the tower crane battery by intelligently judging the battery state and charging only when it is truly needed. By monitoring the initial battery state data of the tower crane battery in real time, including temperature, this embodiment can timely detect potential safety hazards such as overheating. When the battery temperature is abnormal, the system can take corresponding measures such as stopping charging and alarming to ensure the safe operation of the system.

[0070] In some embodiments of the present application, when determining whether to end the charging of the tower crane battery according to the relationship between the real-time battery state data and the charging end condition threshold, where the charging end condition threshold and the charging abnormal condition threshold are preset in advance, it includes:

[0071] The charging end condition threshold includes the maximum power threshold and the maximum charging duration;

[0072] The real-time battery state data includes the real-time charging duration, the real-time battery power, the real-time battery temperature, and the real-time battery voltage;

[0073] When the real-time charging duration is less than the maximum charging duration or the real-time battery power is less than the maximum power threshold, it is determined to end the charging of the tower crane battery;

[0074] When the real-time charging duration is greater than or equal to the maximum charging duration or the real-time battery power is greater than or equal to the maximum power threshold, it is determined to end the charging of the tower crane battery.

[0075] It can be understood that in this embodiment, when the real-time charging duration does not reach the set maximum charging duration or the real-time battery power does not reach the set maximum power threshold, the tower crane battery will continue to be charged to ensure its full charge and reach the best use state. This decision-making method based on multiple parameters can more precisely control the charging process, avoid overcharging or over-discharging phenomena, and thus extend the service life of the battery. At the same time, real-time monitoring of parameters such as battery temperature and voltage helps to timely detect potential charging abnormalities or safety hazards, ensuring the safety and stability of the charging process. When an abnormal situation is detected, the system can take corresponding measures such as pausing charging and issuing an alarm to prevent possible dangers.

[0076] In some embodiments of the present application, the charging abnormal condition threshold includes the battery voltage abnormal threshold and the battery temperature abnormal threshold.

[0077] In some embodiments of the present application, when it is determined not to end the charging of the tower crane battery, an initial adjustment cycle duration is preset. During the initial adjustment cycle duration, the real-time battery state data is processed to obtain battery state cycle processing data. When determining whether to adjust the charging abnormal condition threshold according to the battery state cycle processing data, it includes:

[0078] Obtain the real-time battery temperature and real-time charging duration, and calculate the real-time battery temperature change rate according to the real-time battery temperature, initial battery temperature, and real-time charging duration;

[0079] Preset the highest temperature change rate threshold;

[0080] When the real-time battery temperature change rate is less than the highest temperature change rate threshold, it is determined to assist in judging whether to adjust the charging abnormal condition threshold;

[0081] When the real-time battery temperature change rate is greater than or equal to the highest temperature change rate threshold, it is determined to adjust the charging abnormal condition threshold.

[0082] In some embodiments of the present application, when the real-time battery temperature change rate is less than the highest temperature change rate threshold and it is determined to assist in judging whether to adjust the charging abnormal condition threshold, it includes:

[0083] Obtain the real-time battery voltage and real-time charging duration, and calculate the real-time battery voltage change rate according to the real-time battery voltage, initial battery temperature, and real-time charging duration;

[0084] Preset the highest voltage change rate threshold;

[0085] When the real-time battery voltage change rate is less than the highest voltage change rate threshold, it is determined not to adjust the charging abnormal condition threshold;

[0086] When the real-time battery voltage change rate is greater than or equal to the highest voltage change rate threshold, it is determined to adjust the charging abnormal condition threshold.

[0087] It can be understood that in this embodiment, by real-time monitoring the change rates of the battery temperature and voltage and adjusting the charging abnormal condition threshold based on these change rates, it is possible to more accurately determine whether the battery is in an abnormal state, so as to take timely measures to prevent safety problems such as battery overheating and overcharging. The battery life is closely related to the temperature and voltage changes during its charging and discharging processes. By dynamically adjusting the charging abnormal condition threshold, it can ensure that the battery is charged under more stable and safe conditions, thereby extending the battery life. When the change rates of the battery temperature and voltage are small, maintaining the original charging abnormal condition threshold can ensure the continuous stability of the charging process, avoid frequent interruptions and resumptions of charging, and thus improve the charging efficiency. Since the charging abnormal condition threshold is dynamically adjusted, this embodiment can adapt to the charging requirements of the tower crane battery under different environments. Whether it is high temperature, low temperature or other complex environments, the threshold can be adjusted to ensure the safety and stability of the charging process.

[0088] In some embodiments of the present application, when it is determined to adjust the charging abnormal condition threshold, it includes:

[0089] The real-time threshold of the charging abnormal condition includes: the real-time threshold of battery temperature abnormality and the real-time threshold of battery voltage abnormality;

[0090] Determine a temperature adjustment coefficient according to the real-time change rate of the battery temperature, and multiply the battery temperature abnormality threshold by the temperature adjustment coefficient to obtain the real-time threshold of battery temperature abnormality;

[0091] Determine a voltage adjustment coefficient according to the real-time change rate of the battery voltage, and multiply the battery voltage abnormality threshold by the voltage adjustment coefficient to obtain the real-time threshold of battery voltage abnormality;

[0092] And the temperature adjustment coefficient is in a direct proportional relationship with the real-time change rate of the battery temperature, and the voltage adjustment coefficient is in a direct proportional relationship with the real-time change rate of the battery voltage;

[0093] After determining the real-time threshold of battery temperature abnormality and the real-time threshold of battery voltage abnormality;

[0094] When the real-time battery temperature is greater than the real-time threshold of battery temperature abnormality or the real-time battery voltage is greater than the real-time threshold of battery voltage abnormality, directly end the charging of the tower crane battery and give an early warning;

[0095] When neither the real-time battery temperature is greater than the real-time threshold of battery temperature abnormality nor the real-time battery voltage is greater than the real-time threshold of battery voltage abnormality, continue to charge the tower crane battery.

[0096] In some embodiments of the present application, when it is determined not to adjust the charging anomaly condition threshold, when adjusting the initial adjustment cycle duration according to the battery state cycle processing data to obtain the real-time cycle duration, it includes:

[0097] Select the larger value of the change rate between the real-time change rate of the battery temperature and the real-time change rate of the battery voltage, determine the cycle duration adjustment coefficient according to the larger change rate value, and the initial adjustment cycle duration is proportional to the real-time cycle duration adjustment coefficient, and multiply the initial adjustment cycle duration by the cycle duration adjustment coefficient to obtain the real-time cycle duration.

[0098] It can be understood that in this embodiment, when it is detected that the real-time temperature or voltage of the battery exceeds the dynamically set abnormal real-time threshold, the system will immediately stop charging and give an alarm. This real-time response mechanism ensures that the battery can be processed in a timely manner when an anomaly occurs, reducing the risk of a larger safety accident caused by battery failure. By introducing a temperature adjustment coefficient and a voltage adjustment coefficient, the present application can dynamically adjust the threshold of the charging anomaly condition according to the real-time change rate of the battery temperature and the real-time change rate of the battery voltage. This intelligent management method makes the battery charging process more flexible and efficient, improving the service life and performance of the battery. When it is determined not to adjust the charging anomaly condition threshold, the system will adjust the initial cycle duration according to the battery state cycle processing data to obtain the real-time cycle duration. This adjustment method can ensure that the system monitors the battery state more accurately and efficiently, reducing unnecessary resource waste.

[0099] Refer to Figure 2 As shown, on the other hand, the present invention proposes a tower crane battery charging protection system, which includes:

[0100] A charging judgment module, configured to obtain the initial battery state data of the tower crane battery, determine whether to charge the tower crane battery according to the initial battery state data, when it is determined to charge the tower crane battery, preset the initial charging conditions, charge the tower crane battery based on the initial charging conditions, and obtain the real-time battery state data of the tower crane battery during the charging process;

[0101] Wherein, the initial charging conditions include: an initial charging current and an initial charging voltage;

[0102] An end judgment module, configured to preset a charging end condition threshold and a charging anomaly condition threshold, and determine whether to end the charging of the tower crane battery according to the relationship between the real-time battery state data and the charging end condition threshold;

[0103] A threshold adjustment module, configured to preset an initial adjustment period duration when it is determined that the charging of the tower crane battery is not ended. During the initial adjustment period duration, the real-time battery state data is processed to obtain battery state period processing data, and whether to adjust the charging abnormal condition threshold is determined according to the battery state period processing data;

[0104] An abnormal judgment module, configured to use the adjusted charging abnormal condition threshold as the charging abnormal condition period threshold when it is determined to adjust the charging abnormal condition threshold. When the real-time battery state data is within the range of the charging abnormal condition real-time threshold, the charging of the tower crane battery is directly ended and a warning is given. When it is determined not to adjust the charging abnormal condition threshold, the initial adjustment period duration is adjusted according to the battery state period processing data to obtain a real-time period duration, and the real-time battery state data is processed within the real-time period duration.

[0105] It can be understood that in this embodiment, through the charging judgment module, the system can intelligently judge whether the tower crane battery needs to be charged based on the initial battery state data of the tower crane battery, and set the initial charging conditions after determining the charging. This ensures that the charging process can be carried out according to the actual state of the battery, avoiding unnecessary charging or overcharging, and extending the service life of the battery. By setting the charging end condition threshold and the charging abnormal condition threshold, the end judgment module can accurately judge when to end the charging and react in a timely manner when an abnormal situation occurs. This precise control ensures the safety and efficiency of the charging process. The threshold adjustment module and the abnormal judgment module endow the system with the ability of dynamic adjustment. During the charging process, the system can dynamically adjust the charging abnormal condition threshold and the real-time period duration according to the real-time battery state data, so as to adapt to the charging requirements in different situations. This dynamic adjustment ability makes the system more flexible and reliable. When the real-time battery state data exceeds the set charging abnormal condition period threshold, the system will immediately end the charging and give a warning. This warning mechanism can timely detect potential problems and take corresponding measures to prevent equipment damage or safety accidents caused by abnormal charging.
