Therefore, the monitoring reliability and the monitoring efficiency of the high-voltage cabinet are improved, the reliable operation of the high-voltage cabinet is ensured, and the probability of power failure of the high-voltage cabinet is reduced.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
As shown in fig. 1, in the embodiment of the present application, a method for monitoring a high voltage cabinet based on multiple parameters includes the following steps:
s1: synchronously acquiring a plurality of different parameters of a high-voltage cabinet;
s2: processing all the parameters according to a set constraint strategy and generating a corresponding driving signal;
s3: and controlling the high-voltage cabinet to execute corresponding actions according to the generated driving signal.
In the embodiment of the present application, the constraint strategy has different output results according to the difference of the input parameters, and different driving signals can be generated based on the constraint strategy.
In this embodiment, each monitored parameter is processed according to a set constraint strategy, and different driving signals can be obtained quickly, so that the high-voltage board executes different actions according to different driving signals, and the monitoring automation degree of the high-voltage board is high, that is, the monitoring efficiency is high; the parameters acquired synchronously can quickly obtain a corresponding driving signal based on a unified constraint strategy, and the high-voltage cabinet can execute corresponding actions according to the driving signal.
Different from the prior art, the parameters acquired in the embodiment of the application are diversified, the parameters acquired synchronously are processed and classified according to a constraint strategy set scientifically, a corresponding driving signal is determined according to a classification result, and different countermeasures of the high-voltage cabinet corresponding to different driving signals can simplify the complex multi-parameter acquisition control, improve the countermeasures of the high-voltage cabinet, ensure the reliable operation of the high-voltage cabinet and reduce the probability of power failure of the high-voltage cabinet.
Specifically, the constraint policy includes:
normalizing each parameter;
according to the set weighting coefficient, carrying out weighted summation on all the normalized parameters;
different drive signals are generated according to the result of the weighted summation.
It should be noted that the physical quantities of the parameters are different and are not suitable for direct operation, and the parameters are normalized and then weighted and summed according to the importance of the parameters, so that different driving signals can be generated according to the summation result.
Specifically, the result of the weighted summation is changed within a certain range, a safety boundary is set according to actual conditions or theoretical simulation conditions, in order to ensure the reliability of the electric power operation, the safety boundary is further refined and divided into a plurality of different boundaries to obtain a plurality of sections, each section corresponds to one driving signal, and the driving signals corresponding to different sections are different.
Further, the specific step of generating different driving signals according to the result of the weighted summation includes:
if the weighted summation result exceeds a set first threshold value, the generated driving signal is to cut off the power supply of the high-voltage cabinet;
if the weighted summation result is lower than a set second threshold value, generating a driving signal for keeping the power supply of the high-voltage cabinet on and stopping the high-voltage cabinet fan to sweep wind;
and if the weighted summation result is between the first threshold and the second threshold, generating a driving signal for controlling the high-voltage cabinet fan to sweep wind.
In this embodiment, the first threshold and the second threshold divide the result of weighted summation into three intervals from large to small. If the summation result falls into the interval with the maximum numerical value, directly cutting off the power supply of the high-voltage cabinet; if the summation result falls in the interval between the numerical values, controlling the high-voltage cabinet fan to sweep air so as to relieve the heating problem of the high-voltage cabinet; if the summation result falls in the interval with the minimum numerical value, the high-voltage cabinet is normal, intervention measures are not needed, the high-voltage cabinet is kept in a power supply conduction state, and the high-voltage cabinet fan is not started to sweep air.
Wherein, a plurality of different parameters of the high-voltage board are synchronously collected through the sensor group.
Preferably, the sensor group comprises a temperature sensor and a smoke sensor, wherein,
the temperature sensor is used for collecting the temperature parameters of the high-voltage cabinet, and the smoke intensity sensor is used for collecting the smoke intensity parameters of the high-voltage cabinet.
Still further, the weighting coefficient of the smoke intensity parameter is greater than the temperature parameter. And the weighting coefficient of both is equal to one.
If the smoke intensity parameter is excessive, indicating that there is a greater fire hazard, it is more important for the result of the weighted sum than for high temperatures, so the weighting coefficient of the smoke intensity parameter is required to be greater than the temperature parameter.
In a specific embodiment, a temperature sensor is used for collecting temperature parameters of the high-voltage cabinet, and a smoke degree sensor is used for collecting smoke degree parameters of the high-voltage cabinet; normalizing the collected temperature parameters and the collected smoke intensity parameters, and weighting and summing the normalized temperature parameters and the normalized smoke intensity parameters according to the set weighting coefficients of the parameters to obtain a numerical value; and comparing the value with a set first threshold value and a set second threshold value, generating a first driving signal if the value exceeds the first threshold value, generating a second driving signal if the value is between the first threshold value and the second threshold value, and generating a third driving signal if the value is lower than the second threshold value.
If the first driving signal is generated, the potential safety hazard of the high-voltage cabinet is the highest, and the power supply of the high-voltage cabinet is cut off; if the second driving signal is generated, the situation that a certain potential safety hazard exists in the high-voltage cabinet is shown, and the high-voltage cabinet fan sweeps wind at present; if the third driving signal is generated, the high-voltage cabinet is very safe, and no intervention measures are needed for the high-voltage cabinet.
As a preferred scheme of the embodiment of the present application, the method further includes the steps of:
and drawing a real-time curve graph of each parameter of the high-voltage cabinet according to all the parameters of the high-voltage cabinet which are synchronously acquired.
The real-time curve graph of each parameter reflects the change of the parameter along with time, so that a worker can clearly and intuitively determine the parameter change from the real-time curve graphs, can also predict the parameter trend in the later period according to all the real-time curve graphs, or discover hidden danger manual interference from the real-time curve graphs to assist intervention measures controlled by a driving signal, and the reliability of the high-voltage cabinet is further improved.
In practical applications, the number of the high-voltage cabinets is not unique, and further, if the number of the high-voltage cabinets is multiple, the method includes the following steps:
synchronously collecting all the parameters of the high-voltage cabinets;
according to the constraint strategy, all parameters of each high-voltage cabinet are processed respectively and corresponding driving signals are generated;
and controlling each high-voltage cabinet to execute corresponding action according to each generated driving signal.
In this embodiment, different high-voltage cabinets are independently controlled by respective driving signals according to respective constraint strategies, so that the high-voltage cabinet monitoring method can be applied to a single high-voltage cabinet to expand to a high-voltage cabinet group, and is more suitable for practical application.
Further, the method also comprises the following steps:
and drawing to obtain real-time curve graphs of different parameters of different high-voltage cabinets according to all the parameters of the high-voltage cabinets which are synchronously collected.
The real-time curve graph of each parameter reflects the change of the parameter along with the time, so that the staff can clearly and intuitively determine the parameter change from the real-time curve graphs and can find out the abnormal high-voltage cabinet according to all the real-time curve graphs.
Specifically, the method further comprises the following steps:
and periodically correcting the weighting coefficient according to the obtained real-time curve graphs of different parameters.
And when the high-voltage board is in continuous operation, the variation trend of the real-time curve graph of each parameter is continuously changed, and the weighting coefficient of each parameter is improved or reduced according to the variation trend of each parameter, so that the summation result is continuously adapted to the reality, the countermeasure of the high-voltage board is more accurate, and the monitoring reliability of the high-voltage board is improved.
