Description

Technical Field

[0001] The 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 the advancement of science and technology and the development of military modernization, micro-loading devices are widely used in various types of weapons and equipment due to their small size, powerful functions, and easy portability. However, due to the high requirements of micro-loading devices on power supply and the complex and changeable working environment, how to effectively manage and control the power supply to ensure the stable operation of the micro-loading device has become an urgent problem to be solved.

[0003] Most of the existing power management systems for micro loading devices can only set a threshold for the power output power value, and directly alarm and shut down when it exceeds the threshold. This power management method is relatively rough. In some cases with heavy loads or abnormal conditions, direct alarms will affect the loading efficiency. It is impossible to intelligently judge whether the power supply needs to be cut off or adjusted according to 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: a 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 power supply of the micro-loading device during the working period, obtain the abnormal change value, make a judgment based on the abnormal change value, and generate 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, obtain the power output power abnormality value and the power mutation abnormality value, output the emphasized node value, and determine 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 power supply control power ZXT is obtained;

[0013] Power supply control module: reduces the current power supply 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 operation 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 power supply of the micro-loading device during the power supply 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] The power output of the power supply at the current moment is input into the two-dimensional model of the micro-loading device for regional judgment;

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

[0023] If the power output power of the power supply at the current moment is in the control area, that is, the power output power of the power supply at the current moment 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 collection period is set, and the tilt value at the current moment and the tilt value at the start of the collection period are determined according to the power output power curve of the power supply;

[0025] The slope value at the current moment and the tilt value at the start of the acquisition period are calculated to obtain the tilt change value of the acquisition period;

[0026] The tilt value at the current moment and the tilt value at the start of the acquisition period are input 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, wherein 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 greatly increased in the current period, and has entered the control area from the safe area with a larger power output power, and 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 enters the control area from the safety area with a smaller power output power, then a signal to be processed is generated.

[0032] Furthermore, the emphasized node value is obtained in the following manner:

[0033] Based on the signal to be processed, the output power of the micro-loading device power supply is continuously monitored to obtain the power supply output power abnormality degree value and the power mutation abnormality degree value, and the power supply 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 regulation time node.

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

[0039] The time period from the start time 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 tolerable power value;

[0042] The power deviation value is calculated by ratio with 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 added together 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] Compare 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 the preset adjacent power supply output power difference threshold, it means that the power supply output power at this moment has changed significantly compared with 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 difference between adjacent power supplies corresponding to the signal with a 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 added up to obtain the power mutation abnormality degree value.

[0051] Furthermore, the total power anomaly value is obtained in the following manner:

[0052] When the power supply regulation 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 abnormal regulation time ST; where k is a preset deviation coefficient factor, obtained based on historical data;

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

[0056] A power management method for a micro-loading device is applied to a power management system for a micro-loading device according to claim 1.

[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 easy to understand, the present invention is further explained 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 power supply of the micro-loading device during the working period, obtain the abnormal change value, make a judgment based on the abnormal change value, and generate 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, obtain the power output power abnormality value and the power mutation abnormality value, output the emphasized node value, and determine 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 power supply control power ZXT is obtained;

[0072] Power supply control module: reduces the current power supply 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 operation of the micro-loading device 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 operation of the micro-loading device, and a power supply output power curve is drawn;

[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 safety zone, and the area between the first threshold line and the second threshold line is the control zone; the first threshold line and the second threshold line are empirical values, which are set by the 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 in a normal state and can continue to work; when the power output power of the micro-loading device is in the control area, it means that there is an abnormality in the power operation status of the micro-loading device 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 power supply of the micro-loading device during the working period, obtain the abnormal change value, make a judgment based on the abnormal change value, and generate 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 power supply of the micro-loading device during the power supply 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] The power output of the power supply at the current moment is input into the two-dimensional model of the micro-loading device for regional judgment;

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

[0083] If the power output power of the power supply at the current moment is in the control area, that is, the power output power of the power supply at the current moment 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 collection period is set, and the tilt value at the current moment and the tilt value at the start of the collection period are determined according to the power output power curve of the power supply;

[0085] The slope value at the current moment and the tilt value at the start of the acquisition period are calculated to obtain the tilt change value of the acquisition period;

[0086] The tilt value at the current moment and the tilt value at the start of the acquisition period are input 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, wherein a1 and a2 are both preset proportional coefficients, a1+a2=1, and the values ​​of a1 and a2 represent the 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 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 greatly increased and changed in the current period, and has entered the control area from the safe area with a large power output power, and a power-off signal is generated; wherein, the abnormal change value threshold of the current power output power is an empirical value, which is set by the staff based on experience, indicating that the output power tilt value of the power supply has changed greatly in a short period of time, resulting in the inability to timely and effectively regulate the output power of the power supply, causing the output power of the power supply 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 a small increase change in the current period, and enters the control area from the safe area with a small power output power, and a signal to be processed is generated;

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

[0092] The technical solution of the embodiment of the present invention is as follows: the power output power data of the micro-loading device during the working period is obtained, and a two-dimensional model of the operation of the micro-loading device is constructed; based on the power output power data of the acquisition period, the abnormal change value is obtained, and a judgment is made to generate a control signal; the present invention monitors the power output power of the micro-loading device during the working period in real time, and according to the possible sudden changes in the power output power, real-time analysis and processing are performed to control whether the power supply is powered 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 emphasized node value is output, and the power supply control time node of the micro-loading device is determined according to the emphasized 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 the power supply output power abnormality degree value and the 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 the 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 emphasized node value is greater than or equal to the emphasized node threshold, a signal to be processed is generated; the time point at which the signal to be processed is generated is marked as a power supply control time node;

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

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

[0101] The time period from the start time 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 tolerable power value;

[0104] The power deviation value is calculated by ratio with the power tolerance value to obtain the real-time power mutation degree ratio;

[0105] The real-time power mutation degree ratios of all detection nodes within the monitoring period are added and summed to obtain the power output power abnormality degree value of the power supply;

[0106] In some embodiments, the power mutation abnormality degree value is obtained in the following manner:

[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] Compare 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 the preset adjacent power supply output power difference threshold, it means that the power supply output power at this moment has changed significantly compared with 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 difference between adjacent power supplies corresponding to the signal with a 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 added 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 schemes, when determining the power supply control time node, the area of ​​the region enclosed by the power supply output power curve and the first threshold line during the monitoring period is obtained, marked as the total power abnormality 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 can be tolerated when the power supply output power exceeds the first threshold, which can be obtained based on historical data;

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

[0116] Then obtain the ratio of the power deviation value PC to the power abnormality control time ST to obtain the minimum power control power ZXT; send the obtained minimum power control power ZXT to the power control module, and reduce the current power output power according to the minimum power control power ZXT.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
