[0003] At present, in the area of ​​power consumption supervision of security equipment, only the actual power consumption value of security equipment is supervised, while there is a lack of supervision on the operating status of security equipment during work and the impact of the environment in which it is located. On the one hand, it is easy to lead to inaccurate prediction of power consumption of security equipment, and on the other hand, it is easy to cause security equipment to run for a long time in high temperature and high heat environment, which not only increases power consumption, but also damages the normal use of security equipment. In the later stage, a lot of manpower and material resources will be spent on the maintenance of security equipment.

[0004] To this end, we propose an intelligent monitoring system for power consumption of security equipment suitable for the maintenance of public security equipment to address the above issues. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a system principle block diagram of the present invention. DETAILED DESCRIPTION

[0029] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention. Example 1

[0030] The present invention discloses an intelligent monitoring system for power consumption of security equipment applicable to the maintenance of public security equipment. Figure 1 , including an equipment status information collection unit, an equipment operation supervision unit, an environmental interference supervision unit, a power consumption assessment unit, a feedback analysis unit and an early warning control unit. The equipment status information collection unit is connected to the equipment operation supervision unit and the environmental interference supervision unit in a one-way communication manner, the equipment operation supervision unit and the environmental interference supervision unit are connected to the power consumption assessment unit in a one-way communication manner, the power consumption assessment unit is connected to the feedback analysis unit in a one-way communication manner, and the equipment operation supervision unit, the environmental interference supervision unit, the power consumption assessment unit and the feedback analysis unit are connected to the early warning control unit in a one-way communication manner.

[0031] The device status information collection unit is used to collect the operating data of the security equipment in the operating state and the environmental interference data of the environment in which it is located, wherein the operating data includes the actual power consumption value and the operating parameter value, and sends the operating data and the environmental interference data to the device operation supervision unit and the environmental interference supervision unit respectively;

[0032] After receiving the operation data, the equipment operation supervision unit obtains the operation parameter values ​​within the preset monitoring period and immediately performs power consumption estimation analysis on the operation parameter values. The operation parameter values ​​include the operation power value, operation time effective value and operation temperature value of the security equipment, which are marked as YP, YT and YW respectively. , T 工总 Indicates the working time, T 总 Indicates the total duration of the monitoring period, T 工长 Indicates the maximum single working time, a indicates the preset weight coefficient;

[0033] Generate the equipment power consumption operating value HY through the formula, , where b represents the power coefficient, c represents the temperature coefficient, and the equipment power consumption operation value HY is compared with the preset equipment operation threshold. When the equipment power consumption operation value is greater than or equal to the preset equipment operation threshold, an operation risk signal is generated; when the equipment power consumption operation value is less than the preset equipment operation threshold, no signal is generated;

[0034] The operating power, operating time and operating temperature of security equipment during operation are all factors affecting its power consumption. That is, high operating power, high operating time and high operating temperature will lead to increased power consumption of security equipment. The larger the power consumption value of the equipment used as a reference for power consumption standards, the higher the operating risk.

[0035] The equipment operation supervision unit obtains the actual power consumption value within the preset monitoring period, creates a rectangular coordinate system with the collection time t as the x-axis and the actual power consumption value as the y-axis, and draws a curve of actual power consumption data change in the rectangular coordinate system by plotting points;

[0036] The stored preset critical power consumption value is marked on the y-axis as the preset power consumption value, and a preset straight line is drawn horizontally from the preset power consumption value and horizontally with the x-axis. The power consumption data change curve intersects with the preset straight line, and the monitoring period corresponding to the actual power consumption value above the preset straight line is marked as the peak power consumption period, and the monitoring period corresponding to the actual power consumption value below the preset straight line is marked as the low power consumption period;

[0037] Obtain the total period value of peak power consumption and the total high power consumption within the total period value of peak power consumption, mark the ratio of the total high power consumption to the total period value of peak power consumption as the average peak power consumption, compare the average peak power consumption with the preset peak power consumption value, and generate a peak power consumption danger signal when the ratio of the average peak power consumption to the preset peak power consumption value is greater than or equal to 1; and generate no signal when the ratio of the average peak power consumption to the preset peak power consumption value is less than 1.

[0038] By obtaining multiple actual power consumption values ​​within the monitoring period, and anchoring the multiple actual power consumption values ​​to draw an actual power consumption data change curve, a chart can be used to more clearly show the peak power consumption period within the monitoring period;

[0039] The equipment operation supervision unit sends the actual power consumption value and the obtained equipment power consumption operation value HY to the power consumption assessment unit, and sends the obtained operation risk signal and peak power consumption danger signal to the early warning and control unit. The early warning and control unit displays the risk level of the security equipment operation through text. Example 2

[0040] The environmental interference monitoring unit obtains environmental interference data of the environment in which the security equipment is located within a preset monitoring period, and performs risk assessment on the environmental interference data, wherein the environmental interference data represents the sum of the parts of the environmental parameters exceeding the preset environmental values, and then the product value obtained by normalizing the sum of the parts of the environmental parameters exceeding the preset environmental values ​​and the total number of environmental parameter values ​​corresponding to the parts exceeding the preset environmental values, wherein the environmental parameter represents the product value between the temperature jump value and the humidity jump value, wherein the temperature jump value represents the difference between the maximum environmental temperature value and the average environmental temperature, and the humidity jump value represents the difference between the maximum environmental humidity value and the average environmental humidity;

[0041] The environmental interference data is compared with the preset environmental data. When the environmental interference data is greater than or equal to the preset environmental data, an environmental interference signal is generated, and the difference between the environmental interference data and the preset environmental data is marked as the environmental impact value HQ. When the environmental interference data is less than the preset environmental data, no signal is generated.

[0042] The environmental interference monitoring unit is used to obtain environmental interference data and integrate them to obtain the environmental impact value HQ. The environmental impact value HQ includes the degree of influence of high temperature and high humidity on the operation of the security equipment. That is, the greater the jump in temperature and humidity, the more unstable the environment is and the environment is in an unfavorable environment of high temperature and high humidity. The environmental impact value HQ is sent to the power consumption evaluation unit, and the environmental interference signal is sent to the early warning control unit. The early warning control unit uses text to display the risk warning of the high temperature and high humidity environment in which the security equipment is located during operation.

[0043] After receiving the equipment power consumption operation value HY and environmental impact value HQ, the power consumption evaluation unit obtains the power consumption estimate YG through the formula. , where Q1 and Q2 are preset proportional factor coefficients of the operating power consumption value and the environmental impact value, respectively, to perform power consumption estimation analysis, and obtain the current evaluation floating value and power consumption abnormality signal based on the power consumption estimation value and the actual power consumption value analysis;

[0044] Specifically, a rectangular coordinate system is created with the collection time t as the x-axis and the power consumption estimate YG as the y-axis, and a curve of the estimated power consumption value change is drawn in the rectangular coordinate system by plotting points;

[0045] The actual power consumption data change curve and the estimated power consumption value change curve are uniformly plotted in the same coordinate system, and straight lines are drawn from the beginning and end of the estimated power consumption value change curve to the beginning and end of the actual power consumption data change curve. The two change curves form a closed figure, and the total area value of the closed figure is obtained and marked as the current evaluation floating value;

[0046] Compare the current evaluation floating value with the preset power consumption floating value. If the current evaluation floating value is greater than or equal to the preset power consumption floating value, a power consumption abnormality signal is generated. If the current evaluation floating value is less than the preset power consumption floating value, no signal is generated and the power consumption abnormality signal is sent to the early warning control unit. The early warning control unit also displays the power consumption abnormality warning in the form of text display.

[0047] The power consumption of the security equipment is evaluated and predicted by combining the operating status of the security equipment itself with the environmental conditions. The obtained equipment power consumption operating value HY and environmental impact value HQ are estimated and analyzed to obtain the estimated power consumption value. The estimated power consumption value is compared and analyzed with the actual power consumption value. The accuracy of the power consumption estimate is analyzed through the results, thereby improving the accuracy of the power consumption prediction. Example 3

[0048] The power consumption evaluation unit sends the current evaluation floating value to the feedback analysis unit, and the feedback analysis unit obtains the historical power consumption floating value. The feedback analysis unit performs risk analysis on the current evaluation floating value and the historical power consumption floating value. The specific risk analysis process is as follows: the current evaluation floating value is compared and analyzed with the historical power consumption floating value. The historical power consumption floating value is the evaluation floating value obtained in the same way in the previous monitoring period. It is marked as the historical power consumption floating value and stored in the database, which plays a role in comparing the power consumption floating trends of the previous and next monitoring periods, so as to further improve the accuracy of the current power consumption prediction;

[0049] If the current evaluation floating value is greater than the historical power consumption floating value, an optimization control signal is generated; if the current evaluation floating value is less than or equal to the historical power consumption floating value, no signal is generated, and the obtained optimization control signal is sent to the early warning control unit;

[0050] The accuracy of the estimated power consumption is verified based on the comparison results to improve the accuracy of power consumption prediction. The early warning and control unit makes optimized control processing after receiving the optimized control signal, such as energy-saving measures to avoid long-term opening of security equipment in high temperature and high humidity environments, as well as other optimized system measures, thereby protecting the security equipment.

[0051] In summary: the present invention evaluates and predicts the power consumption of security equipment by combining the operating status of the security equipment itself with the environmental conditions, and estimates and analyzes the obtained equipment power consumption operation value HY and environmental impact value HQ to obtain the power consumption estimate value, thereby improving the accuracy of the power consumption estimate value;

[0052] And based on the estimated power consumption during the monitoring period and the actual power consumption value, a point plotting and drawing analysis is performed to obtain the current assessment floating value. Finally, a risk analysis is performed on the current assessment floating value and the historical power consumption floating value. The accuracy of the estimated power consumption is verified based on the comparison results to improve the accuracy of power consumption prediction. When combined with the analysis from two perspectives: the equipment itself and the environment, it is easy to formulate energy-saving measures to avoid long-term opening of security equipment in high temperature and high humidity environments, as well as other optimization system measures. Not only can reasonable energy-saving measures be formulated according to the power consumption situation, but it also protects the security equipment.
