Description

Technical Field

[0001] The present invention belongs to the technical field of power management, and in particular to a power management system and method for a micro-loading device. Background Art

[0002] With technological advancements and the development of military modernization, micro-loading devices are widely used in various weaponry due to their compact size, powerful functionality, and portability. However, due to their high power requirements and complex and changing operating environments, effective power management and control to ensure stable operation have become pressing challenges.

[0003] Most existing power management systems for micro-loading devices can only set thresholds for the power output value, and directly alarm and shut down when the threshold is exceeded. This power management method is relatively crude. Under some heavy load or abnormal conditions, direct alarm will affect the loading efficiency. It cannot intelligently determine whether the power supply needs to be cut off or regulated based on the degree of abnormal changes, and the safety and stability of the power supply operation are poor.

[0004] To this end, the present invention provides a power management system and method for a micro-loading device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is: the power management system for a micro-loading device described in the present invention comprises:

[0007] Power input module: responsible for receiving external power and converting electrical energy into the form of electrical energy required by the micro-loading device;

[0008] Power supply monitoring module: monitors the power output value of the micro-loading device in real time and constructs an operation model of the micro-loading device; wherein, in the two-dimensional operation model of the micro-loading device, a first threshold line and a second threshold line are set;

[0009] Data processing module: based on the power output power data of the micro-loading device during the power working period, obtains the abnormal change value, makes judgment based on the abnormal change value, and generates a control signal;

[0010] Among them, the control signal includes a power-off signal and a signal to be processed;

[0011] Data analysis module: Based on the signal to be processed, it obtains the power output power abnormality value and the power mutation abnormality value, outputs the emphasized node value, and determines the power supply control time node of the micro-loading device according to the emphasized node value;

[0012] Based on the power supply control time node, the maximum output power value of the power supply and the total power abnormality value are obtained, and the difference is calculated to obtain the total power abnormality control value TKZ; combined with the power deviation value PC, the minimum control power of the power supply ZXT is obtained;

[0013] Power control module: reduces the current power output power according to the minimum control power ZXT.

[0014] Furthermore, the specific construction method of the micro-loading device operation model is as follows:

[0015] The operating time and operating power of the micro-loading device are obtained, and a two-dimensional model of the micro-loading device operation is constructed with time as the X-axis and the operating speed as the Y-axis.

[0016] Substitute the real-time operating power into the two-dimensional model of the micro-loading device and draw the power output power curve;

[0017] Wherein, in the two-dimensional model of the micro-loading device operation, a first threshold line and a second threshold line are set;

[0018] The first threshold line is located below the second threshold line. The area between the first threshold line and the X-axis is the safety zone, and the area between the first threshold line and the second threshold line is the control zone.

[0019] Furthermore, based on the power output power data of the micro-loading device during the power working period, the abnormal change value is obtained, specifically:

[0020] Obtaining the power output power of the micro-loading device at the start of the power working period and the power output power at the current moment;

[0021] Input the current power output of the power supply into the two-dimensional model of the micro-loading device to perform regional judgment;

[0022] If the current power output power is in the safe zone, that is, the current power output power is less than the first threshold, a normal signal is generated;

[0023] If the current power output power is in the control zone, that is, the current power output power is greater than the first threshold line and less than the second threshold line, then an analysis signal is generated;

[0024] Based on the analysis signal, the acquisition period is set, and the tilt value at the current moment and the tilt value at the start of the acquisition period are determined according to the power output power curve of the power supply;

[0025] Calculate the difference between the slope value at the current moment and the tilt value at the start of the acquisition period to obtain the acquisition period tilt change value;

[0026] The tilt value at the current moment and the tilt value at the start of the acquisition period are fed into the variance formula for calculation to obtain the acquisition period tilt variance value;

[0027] The acquisition cycle tilt change value is marked as CX, and the acquisition cycle tilt variance value is marked as FC. The abnormal change value BHZ of the power output power at the current moment is obtained by the formula BHZ=a1*CX+a2*FC, where a1 and a2 are both preset proportional coefficients, and a1+a2=1.

[0028] Furthermore, based on the abnormal change value, a judgment is made to generate a control signal, specifically:

[0029] Compare the abnormal change value BHZ of the power output power at the current moment with the abnormal change value threshold of the power output power at the current moment;

[0030] If the abnormal change value BHZ of the power output power at the current moment is greater than the abnormal change value threshold of the power output power at the current moment, it means that the power output power of the micro-loading device has increased significantly in the current period, and has entered the control area from the safe area with a large power output power, then a power-off signal is generated;

[0031] On the contrary, if the abnormal change value BHZ of the power output power at the current moment is less than or equal to the abnormal change value threshold of the power output power at the current moment, it means that the power output power of the micro-loading device has undergone a small increase in the current period, and has entered the control area from the safe area with a smaller power output power, and a signal to be processed is generated.

[0032] Furthermore, the emphasized node value is obtained as follows:

[0033] Based on the signal to be processed, the output power of the micro-loading device is continuously monitored to obtain the power output power abnormality degree value and the power mutation abnormality degree value. The power output power abnormality degree value and the power mutation abnormality degree value are added together to obtain the emphasized node value.

[0034] Furthermore, the method for obtaining the power control time node is:

[0035] comparing the emphasized node value to an emphasized node threshold;

[0036] If the emphasized node value is less than the emphasized node threshold, a normal signal is generated;

[0037] If the emphasis node value is greater than or equal to the emphasis node threshold, a signal to be processed is generated; and the time point at which the signal to be processed is generated is marked as a power supply control time node.

[0038] Furthermore, the power output power abnormality value is obtained in the following manner:

[0039] The time period from the start of monitoring to the current time is marked as the monitoring period, and several detection nodes are set within the detection period;

[0040] Obtain the power output power of each detection node during the monitoring period, mark it as the real-time power output power during the monitoring period, and calculate the difference between the real-time power output power during the monitoring period and the first threshold to obtain a power deviation value;

[0041] Obtaining a difference between the second threshold and the first threshold, and marking the difference as a power tolerance value;

[0042] Calculate the ratio of the power deviation value to the power tolerance value to obtain the real-time power mutation degree ratio;

[0043] The real-time power mutation degree ratios of all detection nodes within the monitoring period are summed up to obtain the power output power abnormality degree value.

[0044] Furthermore, the power mutation abnormality degree value is obtained in the following manner:

[0045] Obtain the real-time power output power of the power supply during the monitoring period, obtain the real-time power output power of each detection node, and obtain the difference in adjacent power output powers between adjacent detection nodes;

[0046] Comparing the adjacent power supply output power difference with a preset adjacent power supply output power difference threshold;

[0047] If the difference in adjacent power supply output power is greater than a preset threshold value, it indicates that the power supply output power at that moment has changed significantly compared to the previous detection node, and a power change signal is generated.

[0048] If the difference in adjacent power supply output power is less than or equal to the preset adjacent power supply output power difference threshold, it means that the power supply output power at this moment has changed slightly compared with the previous detection node, and a power change normal signal is generated;

[0049] The power output power difference of adjacent power supplies corresponding to the signal with large power change is calculated by ratio with the power tolerance value to obtain the real-time power mutation degree ratio of the detection node;

[0050] The real-time power mutation degree ratios of all detection nodes within the monitoring period are summed up to obtain the power mutation abnormality degree value.

[0051] Furthermore, the method for obtaining the total power abnormality value is:

[0052] When the power supply control time node is determined, the area of ​​the region enclosed by the power supply output power curve and the first threshold line within the monitoring period is obtained and marked as the total power abnormality value.

[0053] Furthermore, the minimum control power ZXT of the power supply is obtained as follows:

[0054] By formula Obtain the power abnormality control time ST; where k is the preset deviation coefficient factor, obtained based on historical data;

[0055] Then, the ratio of the power deviation value PC to the power abnormality control time ST is obtained to obtain the minimum control power ZXT of the power supply.

[0062] Figure 2 It is a structural schematic diagram of the mobile mechanism of the present invention. DETAILED DESCRIPTION

[0063] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0064] Example 1

[0065] like Figure 1-Figure 2 As shown, a power management system for a micro-loading device includes a power management system for a micro-loading device, including

[0066] Power input module: responsible for receiving external power and converting electrical energy into the form of electrical energy required by the micro-loading device;

[0067] Power supply monitoring module: monitors the power output value of the micro-loading device in real time and constructs an operation model of the micro-loading device; wherein, in the two-dimensional operation model of the micro-loading device, a first threshold line and a second threshold line are set;

[0068] Data processing module: based on the power output power data of the micro-loading device during the power working period, obtains the abnormal change value, makes judgment based on the abnormal change value, and generates a control signal;

[0069] Among them, the control signal includes a power-off signal and a signal to be processed;

[0070] Data analysis module: Based on the signal to be processed, it obtains the power output power abnormality value and the power mutation abnormality value, outputs the emphasized node value, and determines the power supply control time node of the micro-loading device according to the emphasized node value;

[0071] Based on the power supply control time node, the maximum output power value of the power supply and the total power abnormality value are obtained, and the difference is calculated to obtain the total power abnormality control value TKZ; combined with the power deviation value PC, the minimum control power of the power supply ZXT is obtained;

[0072] Power control module: reduces the current power output power according to the minimum control power ZXT.

[0073] In some embodiments, the operating time and operating power of the power supply of the micro-loading device are obtained, and a two-dimensional model of the micro-loading device operation is constructed with time as the X-axis and the operating speed as the Y-axis. The real-time operating power is substituted into the two-dimensional model of the micro-loading device operation, and a power supply output power curve is plotted;

[0074] Wherein, in the two-dimensional model of the micro-loading device operation, a first threshold line and a second threshold line are set;

[0075] The first threshold line is below the second threshold line. The area between the first threshold line and the X-axis is the safe zone, and the area between the first and second threshold lines is the control zone. The first and second threshold lines are empirical values ​​and are set by staff based on experience.

[0076] It should be noted that when the power output power of the micro-loading device is in the safe area, it means that the power operation status of the micro-loading device is normal and can continue to work; when the power output power of the micro-loading device is in the control area, it means that the power operation status of the micro-loading device is abnormal and the power output power of the micro-loading device needs to be controlled.

[0077] Data processing module: based on the power output power data of the micro-loading device during the power working period, obtains the abnormal change value, makes judgment based on the abnormal change value, and generates a control signal;

[0078] Among them, the control signal includes a power-off signal and a signal to be processed;

[0079] In some embodiments, based on the power output power data of the micro-loading device during the power working period, the abnormal change value is obtained, specifically:

[0080] Obtaining the power output power of the micro-loading device at the start of the power working period and the power output power at the current moment;

[0081] Input the current power output of the power supply into the two-dimensional model of the micro-loading device to perform regional judgment;

[0082] If the current power output power is in the safe zone, that is, the current power output power is less than the first threshold, a normal signal is generated;

[0083] If the current power output power is in the control zone, that is, the current power output power is greater than the first threshold line and less than the second threshold line, then an analysis signal is generated;

[0084] Based on the analysis signal, the acquisition period is set, and the tilt value at the current moment and the tilt value at the start of the acquisition period are determined according to the power output power curve of the power supply;

[0085] Calculate the difference between the slope value at the current moment and the tilt value at the start of the acquisition period to obtain the acquisition period tilt change value;

[0086] The tilt value at the current moment and the tilt value at the start of the acquisition period are fed into the variance formula for calculation to obtain the acquisition period tilt variance value;

[0087] The acquisition cycle tilt change value is marked as CX, and the acquisition cycle tilt variance value is marked as FC. The abnormal change value BHZ of the power output power at the current moment is obtained by the formula BHZ = a1*CX+a2*FC, where a1 and a2 are preset proportional coefficients, a1+a2=1, and the values ​​of a1 and a2 represent the degree of influence of the acquisition cycle tilt change value and the acquisition cycle tilt variance value on the abnormal change value;

[0088] Compare the abnormal change value BHZ of the power output power at the current moment with the abnormal change value threshold of the power output power at the current moment;

[0089] If the current power output power abnormal change value BHZ is greater than the current power output power abnormal change value threshold, it means that the power output power of the micro-loading device has increased significantly during the current period, entering the control zone from the safe zone with a large power output power, and a power-off signal is generated. The current power output power abnormal change value threshold is an empirical value set by the staff based on experience. It indicates that the power output power tilt value has changed significantly in a short period of time, resulting in the inability to timely and effectively control the power output power, causing the power output power to fail.

[0090] On the contrary, if the abnormal change value BHZ of the power output power at the current moment is less than or equal to the abnormal change value threshold of the power output power at the current moment, it means that the power output power of the micro-loading device has undergone a small increase in the current period, and has entered the control area from the safe area with a small power output power, and a signal to be processed is generated;

[0091] It should be explained that the abnormal change value of the power supply output power at the current moment indicates the degree of change in the slope of the power supply output power curve during the collection period ending at the current moment. The collection period slope change value is the change in the slope value from the endpoint at the start of the collection period to the endpoint at the current moment. The greater the change in the slope value between the two endpoints, the greater the change in the power supply output power curve during the current period. The collection period slope variance value is the degree of change in the slope value during the collection period. The greater the overall change, the greater the change in the power supply output power curve trend during the current period.

[0092] The technical solution of an embodiment of the present invention is as follows: power output power data of a micro-loading device during its working period is obtained, and a two-dimensional operation model of the micro-loading device is constructed; abnormal change values ​​are obtained based on the power output power data of the acquisition period, and judgment is performed to generate a control signal; the present invention monitors the power output power of the micro-loading device during its working period in real time, performs real-time analysis and processing based on possible sudden changes in the power output power, and controls whether the power supply is cut off for protection or forcibly regulated, thereby ensuring the safety of the power supply operation of the micro-loading device.

[0093] Example 2

[0094] Based on the signal to be processed, the power output power abnormality degree value and the power mutation abnormality degree value are obtained, and the emphasis node value is output. The power supply control time node of the micro-loading device is determined according to the emphasis node value;

[0095] In some embodiments, based on the signal to be processed, the output power of the power supply of the micro-loading device is continuously monitored to obtain a power supply output power abnormality degree value and a power mutation abnormality degree value, and the power supply output power abnormality degree value and the power mutation abnormality degree value are added and summed to obtain an emphasized node value;

[0096] comparing the emphasized node value to an emphasized node threshold;

[0097] If the emphasized node value is less than the emphasized node threshold, a normal signal is generated;

[0098] If the emphasis node value is greater than or equal to the emphasis node threshold, a signal to be processed is generated; the time point when the signal to be processed is generated is marked as a power supply control time node;

[0099] It should be explained that: the normal signal indicates that the output power of the micro-loading device power supply is operating under the condition that it is higher than the first threshold value, the continuity of the power supply output power and the degree of change in the power supply output power are low, and have not reached the warning level of the micro-loading device power supply, that is, the micro-loading device power supply can continue to complete the power output work without stopping operation; on the contrary, the emphasis signal indicates that the output power of the micro-loading device power supply is operating under the condition that it is higher than the first threshold value, the continuity of the higher power supply output power and the degree of change in the speed are large, reaching the warning level of the micro-loading device power supply. If the output power of the micro-loading device power supply is not adjusted in time, it is very likely to cause an overload fault to the micro-loading device power supply, resulting in damage to the micro-loading device power supply;

[0100] In some embodiments, the abnormality level of the power output power is obtained by:

[0101] The time period from the start of monitoring to the current time is marked as the monitoring period, and several detection nodes are set within the detection period;

[0102] Obtain the power output power of each detection node during the monitoring period, mark it as the real-time power output power during the monitoring period, and calculate the difference between the real-time power output power during the monitoring period and the first threshold to obtain a power deviation value;

[0103] Obtaining a difference between the second threshold and the first threshold, and marking the difference as a power tolerance value;

[0104] Calculate the ratio of the power deviation value to the power tolerance value to obtain the real-time power mutation degree ratio;

[0105] The power output power abnormality value is obtained by summing up the real-time power mutation degree ratios of all detection nodes during the monitoring period;

[0106] In some embodiments, the power mutation abnormality degree value is obtained as follows:

[0107] Obtain the real-time power output power of the power supply during the monitoring period, obtain the real-time power output power of each detection node, and obtain the difference in adjacent power output powers between adjacent detection nodes;

[0108] Comparing the adjacent power supply output power difference with a preset adjacent power supply output power difference threshold;

[0109] If the difference in adjacent power supply output power is greater than a preset threshold value, it indicates that the power supply output power at that moment has changed significantly compared to the previous detection node, and a power change signal is generated.

[0110] If the difference in adjacent power supply output power is less than or equal to the preset adjacent power supply output power difference threshold, it means that the power supply output power at this moment has changed slightly compared with the previous detection node, and a power change normal signal is generated;

[0111] The power output power difference of adjacent power supplies corresponding to the signal with large power change is calculated by ratio with the power tolerance value to obtain the real-time power mutation degree ratio of the detection node;

[0112] The real-time power mutation degree ratios of all detection nodes within the monitoring period are summed up to obtain the power mutation abnormality degree value;

[0113] Based on the power supply control time node, the current power supply output power is controlled and the minimum power supply control power ZXT is output;

[0114] In some real-time solutions, when determining the power supply control time node, the area enclosed by the power supply output power curve and the first threshold line during the monitoring period is obtained, marked as the total power anomaly value, and then the maximum output power value of the power supply is obtained; the maximum output power value of the power supply is the maximum output power value that the power supply can withstand when the output power exceeds the first threshold, and can be obtained based on historical data;

[0115] Calculate the difference between the maximum output power value of the power supply and the total power abnormality value to obtain the total power abnormality control value TKZ; combined with the power deviation value PC, through the formula Obtain the power abnormality control time ST; where k is the preset deviation coefficient factor, obtained based on historical data;

[0116] Then, the ratio of the power deviation value PC to the power abnormality control time ST is obtained to obtain the minimum power control power ZXT. The obtained minimum power control power ZXT is sent to the power control module, and the current power output power is reduced according to the minimum power control power ZXT.
