Description

Technical Field

[0001] The present invention relates to the technical field of power supply operation detection, and in particular to an AC / DC power supply operation detection and control system based on data analysis. Background Art

[0002] AC / DC power supplies are devices that can provide AC or DC output and are widely used in various electronic devices and power systems. They are used to drive various motors, automated production line equipment, and provide stable power for industrial control systems.

[0003] However, in the existing technology, it is impossible to evaluate the control performance of the power supply, nor is it possible to evaluate the operation compatibility, accurately perform operation inspection and control, and cannot detect the operating status of the power supply and cannot reasonably control it, which reduces the operating efficiency of the power supply and increases the risk of power supply operation failure.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and to propose an AC and DC power supply operation monitoring system based on data analysis.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The AC and DC power supply operation inspection and control system based on data analysis includes a power supply operation and control center, which is connected to a control performance evaluation unit, a compatibility detection unit, and a data processing and prediction unit;

[0008] The control performance evaluation unit evaluates the control performance of the power supply, collects control deviation information and deviation frequency information, and infers whether the control performance of the power supply is normal based on the information comparison. If not, the control performance is adjusted; if yes, the monitoring continues;

[0009] The compatibility detection unit performs compatibility detection on the power supply operation process, collects electromagnetic floating impact data and electromagnetic interference impact data, and infers whether the power supply compatibility test is qualified based on data analysis. If yes, it continues monitoring; if not, it performs operating environment control;

[0010] The data processing and prediction unit collects and processes the power supply operation data, and makes operation predictions based on the collected and processed data. It collects the minimum value deviation and floating information deviation, and makes operation predictions based on numerical comparison.

[0011] As a preferred embodiment of the present invention, the control deviation information and the deviation frequency information are respectively the deviation between the actual control value and the actual value of the operating parameters corresponding to different power supply operating scenarios, and the deviation rate floating span of the operating parameter regulation under different power supply operating scenarios.

[0012] As a preferred embodiment of the present invention, if the control deviation information exceeds a numerical deviation threshold, or the deviation frequency information exceeds a floating span threshold, a control performance adjustment signal is generated;

[0013] If the control deviation information does not exceed the numerical deviation threshold, and the deviation frequency information does not exceed the floating span threshold, a control performance qualified signal is generated and sent to the power supply operation and control center.

[0014] As a preferred embodiment of the present invention, the electromagnetic floating impact data and the electromagnetic interference impact data are respectively the frequency rise span of the deviation frequency of the power supply operation parameter control when the external electromagnetic intensity in the power supply operation environment increases, and the missed recognition deviation frequency of the power supply operation instruction transmission signal within the external electromagnetic intensity range of the current power supply operation environment.

[0015] As a preferred embodiment of the present invention, if the electromagnetic floating impact data exceeds the frequency rising span threshold, or the electromagnetic interference impact data exceeds the missed identification deviation frequency threshold, a low compatibility performance signal is generated;

[0016] If the electromagnetic floating impact data does not exceed the frequency rising span threshold, and the electromagnetic interference impact data does not exceed the missed identification deviation frequency threshold, a compatibility high-performance signal is generated.

[0017] As a preferred embodiment of the present invention, the process of the data processing prediction unit is as follows:

[0018] The operating parameters of the power supply are collected, and the tolerance range of the power supply corresponding to the electromagnetic intensity is collected, and the operating environment outside the electromagnetic intensity tolerance range is marked as an interference environment, and vice versa. The lowest value of the floating span mean of the power supply operating parameters after the interference environment is transformed into the normal environment, as well as the lowest value of the floating span mean of the power supply operating parameters under the normal environment are collected, and the lowest value deviation is obtained based on the comparison of the lowest values; the floating information of the power supply operating parameters under the interference environment is collected, and the specific floating information is the floating span and the floating frequency. The floating information of the power supply operating parameters under the normal environment is collected, and the floating information deviation is obtained based on the floating information comparison.

[0019] As a preferred embodiment of the present invention, the minimum value deviation and the floating information deviation amount are compared with the minimum value deviation threshold and the floating information deviation amount threshold respectively:

[0020] If the minimum value deviation exceeds the minimum value deviation threshold, or the floating information deviation amount does not exceed the floating information deviation amount threshold, a fault prediction risk signal is generated; if the minimum value deviation does not exceed the minimum value deviation threshold, and the floating information deviation amount exceeds the floating information deviation amount threshold, a fault prediction safety signal is generated.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the control performance of the power supply is evaluated, and whether the power supply control performance meets the actual needs is inferred based on the operation process of the power supply, so as to avoid the inability to accurately adjust parameters and control stability when the power supply is running, thereby reducing the operating efficiency of the power supply; a compatibility test is performed on the power supply operation process, and the electromagnetic influence of the operating environment around the power supply can be inferred based on the power supply compatibility test. At the same time, the degree of electromagnetic influence on the power supply can be inferred based on the compatibility performance, so as to facilitate timely electromagnetic interference control, reduce the risk of power supply failure, and ensure the real-time parameter control stability of the power supply operation task.

[0023] 2. In the present invention, the power supply operation data is collected and processed, and operation prediction is performed based on the collection and processing, so as to infer whether there is any abnormality in the power supply operation status, so as to facilitate timely fault warning, which is conducive to avoiding the fault before it occurs, and can also perform fault emergency control when the fault occurs to reduce the impact of the fault.

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1-Figure 2As shown, an AC / DC power supply operation inspection and control system based on data analysis includes a power supply operation and control center, which is communicatively connected to a control performance evaluation unit, a compatibility detection unit, and a data processing and prediction unit. This system is used for operation inspection and control of AC / DC power supplies, hereinafter collectively referred to as power supplies.

[0030] The power supply operation and control center generates a control performance evaluation signal and sends it to the control performance evaluation unit. After receiving the control performance evaluation signal, the control performance evaluation unit evaluates the control performance of the power supply and infers whether the power supply control performance meets the actual requirements based on the power supply operation process, so as to avoid the inability to accurately adjust parameters and control stability during power supply operation, thereby reducing the operating efficiency of the power supply.

[0031] The deviation between the actual control value and the actual value of the operating parameters corresponding to different operating scenarios of the power supply is collected. At the same time, the deviation rate floating span of the operating parameter regulation under different operating scenarios of the power supply is collected, and the deviation between the actual control value and the actual value of the operating parameters corresponding to different operating scenarios of the power supply and the deviation rate floating span of the operating parameter regulation under different operating scenarios of the power supply are marked as control deviation information and deviation frequency information respectively. It should be explained that the operating parameters are expressed as parameters such as the operating voltage and current of the power supply, and the deviation rate is expressed as the ratio of the actual gap value of the parameter to the regulation value;

[0032] Compare the deviation between the actual control value and the actual value of the operating parameters corresponding to different power supply operating scenarios, and the floating span of the deviation rate of the operating parameter control under different power supply operating scenarios with the numerical deviation threshold and the floating span threshold respectively:

[0033] If the deviation between the actual control value and the actual value corresponding to the operating parameter under different operating scenarios of the power supply exceeds the numerical deviation threshold, or the floating span of the deviation rate of the operating parameter regulation under different operating scenarios of the power supply exceeds the floating span threshold, it is inferred that the control performance evaluation of the power supply operation stage is abnormal, and a control performance adjustment signal is generated and sent to the power supply operation and control center. After receiving the control performance adjustment signal, the power supply operation and control center adjusts the operating parameter control performance of the power supply to reduce the numerical deviation of the operating parameter control;

[0034] If the deviation between the actual control value and the actual value corresponding to the operating parameter under different power supply operation scenarios does not exceed the value deviation threshold, and the floating span of the deviation rate of the operating parameter control under different power supply operation scenarios does not exceed the floating span threshold, it is inferred that the control performance evaluation of the power supply operation stage is normal, and a control performance qualified signal is generated and sent to the power supply operation and control center;

[0035] At the same time, a compatibility detection signal is generated and sent to the compatibility detection unit. After receiving the compatibility detection signal, the compatibility detection unit performs a compatibility detection on the power supply operation process. Based on the power supply compatibility detection, the electromagnetic influence of the operating environment around the power supply can be inferred. At the same time, the degree of electromagnetic influence on the power supply can be inferred based on the compatibility performance, so as to facilitate timely electromagnetic interference control, reduce the risk of power supply failure, and ensure the real-time parameter control stability of the power supply operation task;

[0036] The frequency rise span of the deviation frequency of the power supply operation parameter control when the external electromagnetic intensity in the power supply operation environment increases is collected, and the missed identification deviation frequency of the power supply operation instruction transmission signal within the external electromagnetic intensity range of the current power supply operation environment is obtained. The frequency rise span of the deviation frequency of the power supply operation parameter control when the external electromagnetic intensity in the power supply operation environment increases and the missed identification deviation frequency of the power supply operation instruction transmission signal within the external electromagnetic intensity range of the current power supply operation environment are marked as electromagnetic floating impact data and electromagnetic interference impact data, respectively, and compared with the frequency rise span threshold and the missed identification deviation frequency threshold, respectively:

[0037] If the frequency rise span of the deviation frequency of the power supply operation parameter control exceeds the frequency rise span threshold when the external electromagnetic intensity in the power supply operation environment increases, or the missed identification deviation frequency of the power supply operation instruction transmission signal within the external electromagnetic intensity range of the current power supply operation environment exceeds the missed identification deviation frequency threshold, it is inferred that the compatibility detection during the power supply operation process is abnormal, and a low compatibility performance signal is generated and sent to the power supply operation control center. After receiving the low compatibility performance signal, the power supply operation control center controls the electromagnetic intensity of the power supply operation environment to prevent the high electromagnetic intensity from affecting the power supply operation;

[0038] If the frequency rise span of the deviation frequency of the power supply operation parameter control when the external electromagnetic intensity in the power supply operation environment increases does not exceed the frequency rise span threshold, and the missed identification deviation frequency of the power supply operation instruction transmission signal within the external electromagnetic intensity range of the current power supply operation environment does not exceed the missed identification deviation frequency threshold, it is inferred that the compatibility detection during the power supply operation process is normal, and a high-performance compatibility signal is generated and sent to the power supply operation control center; after the power supply operation control center receives the high-performance compatibility signal, the current type of power supply is given priority when there is high magnetic field intensity interference in the power supply operation environment;

[0039] After completing the compatibility test, the power supply operation and control center generates a data processing prediction signal and sends the data processing prediction signal to the data processing prediction unit;

[0040] After receiving the data processing prediction signal, the data processing prediction unit collects and processes the power supply operation data, and performs operation prediction based on the collected and processed data, thereby inferring whether there is any abnormality in the power supply operation state, so as to provide timely fault warning, which is conducive to avoiding the fault before it occurs, and can also perform fault emergency control when the fault occurs to reduce the impact of the fault;

[0041] Collect the operating parameters of the power supply and the electromagnetic intensity tolerance range of the power supply. Mark the operating environment outside the electromagnetic intensity tolerance range as an interference environment, and mark it as a normal environment otherwise.

[0042] Collect the lowest mean floating span value of the power supply operating parameters after the interference environment is transformed into a normal environment, as well as the lowest mean floating span value of the power supply operating parameters under the normal environment, and obtain the lowest value deviation based on the comparison of the lowest values;

[0043] Collect floating information of power supply operating parameters under interference environment, specifically floating information is floating span and floating frequency. Collect floating information of power supply operating parameters under normal environment, and obtain floating information deviation based on floating information comparison, wherein the floating information deviation is expressed as floating span deviation value and floating frequency deviation value.

[0044] Compare the minimum deviation and the floating information deviation amount to the minimum deviation threshold and the floating information deviation amount threshold respectively:

[0045] If the minimum value deviation exceeds the minimum value deviation threshold, or the floating information deviation does not exceed the floating information deviation threshold, it is inferred that there is a performance impact risk in the current power supply operation process, and a fault prediction risk signal is generated and sent to the power supply operation and control center. After receiving the fault prediction risk signal, the power supply operation and control center performs internal component performance testing on the power supply to facilitate timely operation environment adjustment;

[0046] If the minimum value deviation does not exceed the minimum value deviation threshold, and the floating information deviation exceeds the floating information deviation threshold, it is inferred that there is no performance impact risk during the current power supply operation process, and a fault prediction safety signal is generated and sent to the power supply operation and control center.

[0047] When the present invention is in use, the control performance evaluation unit performs control performance evaluation on the power supply, collects control deviation information and deviation frequency information, and infers whether the control performance of the power supply is normal based on information comparison. If not, the control performance is adjusted; if yes, monitoring is continued; the compatibility detection unit performs compatibility detection on the power supply operation process, collects electromagnetic floating impact data and electromagnetic interference impact data, and infers whether the power supply compatibility detection is qualified based on data analysis. If yes, monitoring is continued; if not, operating environment control is performed; the data processing and prediction unit collects and processes the power supply operation data, and performs operation prediction based on the collected and processed data, collects the minimum value deviation and the floating information deviation amount, and performs operation prediction based on numerical comparison.
