[0009] The instruction execution monitoring module 11 obtains and analyzes the control performance data of the pressure regulating pump 21 and the needle valve 22, and generates a qualified signal or an unqualified signal according to the analysis results, and sends the signal to the display terminal 30 for display; when the display terminal 30 receives the unqualified signal, it will issue a warning message;

[0010] Based on the early warning information, the management personnel use the control system 10 to improve and optimize the pressure regulating pump 21 and the needle valve 22.

[0011] In one embodiment of the present invention, the workflow of the instruction execution monitoring module 11 includes:

[0017] The interval between the third moment and the fourth moment is marked as the needle valve control time value;

[0018] When the control opening instruction is completed, the deviation value of the actual opening data of the needle valve 22 compared with the standard opening data corresponding to the corresponding control opening instruction is marked as the opening deviation value;

[0021] Obtain instruction execution detection values ​​based on the pressure-stabilizing pump control detection value, the pressure-stabilizing pump control abnormal value, the needle valve control detection value, and the needle valve control abnormal value;

[0022] The instruction execution detection value is compared with the preset instruction execution detection threshold; if the instruction execution detection value exceeds the preset instruction execution detection threshold, it indicates that the control execution status of the control system 10 is poor, and corresponding improvement and optimization measures need to be taken in time, and an instruction execution unqualified signal is generated; if the instruction execution detection value does not exceed the preset instruction execution detection threshold, it indicates that the control execution status of the control system 10 is good, and an instruction execution qualified signal is generated.

[0023] In one embodiment of the present invention, the needle valve control value is obtained by the following formula:

[0024] RF=ew1*RP+ew2*RL;

[0025] Where RF is the needle valve control measurement value, RP is the needle valve control time value, RL is the opening deviation value, and ew1 and ew2 are two different needle valve control preset proportional coefficients.

[0036] The brightness adjustment value is compared with all preset brightness adjustment value ranges one by one, and the display brightness corresponding to the preset brightness adjustment value range containing the corresponding brightness adjustment value is marked as the adjustment brightness, so that the display terminal 30 displays according to the adjustment brightness.

[0037] In one embodiment of the present invention, the brightness adjustment value is obtained by the following formula:

[0038] ;

[0039] Where LP is the brightness adjustment value, LX is the ambient brightness, LH is the ambient dust value, LR is the human-machine distance detection value, LY is the human-machine angle deviation value, and h1, h2, h3, and h4 are different brightness adjustment preset proportional coefficients.

[0040] In one embodiment of the present invention, the display control module 12 evaluates the operating status of the display terminal 30 through display operation analysis to generate a display operation unqualified signal or a display operation qualified signal, and when the display operation unqualified signal is generated, the display terminal issues a corresponding early warning to remind the management personnel to inspect and repair the display terminal in time.

[0041] In one embodiment of the present invention, the display control module 12 evaluates the operating status of the display terminal 30 through display operation analysis, including the following steps:

[0042] Collect the actual display brightness of the display terminal 30, and mark the deviation value of the actual display brightness compared to the set standard brightness as the display brightness detection value;

[0043] Collect the internal temperature of the display terminal 30 and mark it as a display temperature detection value, and collect the vibration data and noise data generated by the display terminal 30 during operation, and mark them as a display vibration detection value and a display noise detection value respectively;

[0044] Obtain the display operation value based on the display brightness inspection value, display temperature inspection value, vibration data and noise data;

[0045] The display operation value is numerically compared with the preset display operation threshold. If the display operation value exceeds the preset display operation threshold, it indicates that the display performance of the display terminal is poor, and a display operation unqualified signal is generated; if the display operation value does not exceed the preset display operation threshold, it indicates that the display performance of the display terminal is good, and a display operation qualified signal is generated.

[0046] In one embodiment of the present invention, the pipeline leakage simulation test device 20 includes a flow meter 23, a measuring cup 24 and a gravity sensor 25; the flow meter 23 is located on the water pipe between the pressure-stabilizing pump 21 and the needle valve 22, and the measuring cup 24 is set on the gravity sensor 25 and is located at the water outlet of the water pipe, which receives the water discharged from the water pipe; the gravity sensor 25 is used for weighing; the flow meter 23 and the gravity sensor 25 are communicated with the control system 10 and feed back flow data and weight data to the control system 10.

[0051] To facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described with reference to the accompanying drawings.

[0052] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0053] Example 1

[0054] See also Figure 1 and Figure 2 As shown, the present invention provides a pipeline leakage simulation test system, which includes a control system 10 , a pipeline leakage simulation test device 20 and a display terminal 30 .

[0055] The control system 10 is communicatively connected to the display terminal 30 and includes an instruction execution monitoring module 11. The pipeline leakage simulation test device 20 includes a pressure-stabilizing pump 21 and a needle valve 22, which are sequentially arranged on the water pipe according to the flow direction of the water. The control system 10 is communicatively connected to the pressure-stabilizing pump 21 and the needle valve 22.

[0056] The instruction execution monitoring module 11 acquires and analyzes the control performance data of the pressure-stabilizing pump 21 and needle valve 22. Based on the analysis results, it generates a pass signal or a fail signal, which it then sends to the display terminal 30 for display. Upon receiving a fail signal, the display terminal 30 issues an early warning. Based on this warning, management personnel use the control system 10 to optimize the pressure-stabilizing pump 21 and needle valve 22 to ensure subsequent control performance.

[0057] In one embodiment of the present invention, the specific operation process of the instruction execution monitoring module 11 is as follows:

[0058] The time when the control system 10 issues a control state instruction to the pressure stabilizing pump 21 is collected and marked as the first time, and the time when the pressure stabilizing pump 21 executes the control instruction is collected and marked as the second time.

[0059] The interval between the first moment and the second moment is marked as the voltage-stabilizing pump control time value.

[0060] Calculate the average of all the voltage-stabilizing pump control time values ​​within unit time to obtain the voltage-stabilizing pump control detection value.

[0061] The percentage of the number of stabilizing pump control time values ​​exceeding the preset stabilizing pump control time threshold per unit time is marked as the stabilizing pump control abnormal value. The larger the value of the stabilizing pump control check value and the stabilizing pump control abnormal value, the worse the control execution efficiency of the stabilizing pump 21.

[0062] The time when the control system 10 issues the opening control instruction to the needle valve 22 is recorded as the third time, and the time when the needle valve 22 completes the opening adjustment is recorded as the fourth time.

[0063] The interval between the third moment and the fourth moment is marked as the needle valve control time value.

[0064] When the control opening instruction is completed, the deviation value of the actual opening data of the needle valve 22 compared with the standard opening data corresponding to the corresponding control opening instruction is marked as the opening deviation value.

[0065] The needle valve control measurement value is obtained based on the needle valve control time value and the opening detection value.

[0066] In this embodiment, the needle valve control value is obtained by the following formula:

[0067] RF=ew1*RP+ew2*RL;

[0068] Where RF is the needle valve control value, RP is the needle valve control time value, RL is the opening deviation value, and ew1 and ew2 are two different preset proportional coefficients for needle valve control. The values ​​of ew1 and ew2 are both greater than zero, and a larger value of the needle valve control value RF indicates worse performance of the corresponding control process for needle valve 22.

[0069] The average of all needle valve control measurement values ​​within a unit time is calculated to obtain the needle valve control detection value. The percentage of needle valve control measurement values ​​exceeding the preset needle valve control measurement value threshold within a unit time is marked as the needle valve control abnormal value. It should be noted that the larger the needle valve control detection value and the needle valve control abnormal value, the worse the overall performance of the needle valve 22 control execution.

[0070] The instruction execution detection value is obtained according to the pressure-stabilizing pump control detection value, the pressure-stabilizing pump control abnormal value, the needle valve control detection value and the needle valve control abnormal value.

[0071] In this embodiment, the instruction execution detection value is obtained by the following formula:

[0072] ;

[0073] Where WX is the instruction execution detection value, WF is the pressure regulating pump control error value, WP is the needle valve control error value, WY is the pressure regulating pump control detection value, WK is the needle valve control detection value, ry1, ry2, ry3, ry4 are different comprehensive control proportional coefficients. The values ​​of ry1, ry2, ry3, ry4 are all positive numbers, and the larger the value of the instruction execution detection value WX, the worse the control execution status of the control system 10 is.

[0074] The instruction execution detection value is compared with a preset instruction execution detection threshold. If the instruction execution detection value exceeds the preset instruction execution detection threshold, it indicates that the control execution status of the control system 10 is poor, and corresponding improvement and optimization measures need to be taken in a timely manner, and an instruction execution failure signal is generated. If the instruction execution detection value does not exceed the preset instruction execution detection threshold, it indicates that the control execution status of the control system 10 is good, and an instruction execution pass signal is generated.

[0075] See also Figure 1As shown, in one embodiment of the present invention, the pipeline leakage simulation test device 20 includes a flow meter 23, a measuring cup 24, a gravity sensor 25, and a pressure sensor 26; the flow meter 23 is located on the water pipe between the pressure regulating pump 21 and the needle valve 22, the measuring cup 24 is set on the gravity sensor 25 and is located at the water outlet of the water pipe, which receives the water discharged from the water pipe, and the gravity sensor 25 is used for weighing. The flow meter 23 and the gravity sensor 25 are connected to the control system 10 for communication, and the flow data and weight data are fed back to the control system 10. The data can be compared and used to measure the amount of pipeline leakage. The pressure sensor 26 detects the pressure in the water pipe and feeds the pressure data back to the control system 10. Preferably, the length of the water pipe is 400 meters.

[0076] Example 2

[0077] See also Figure 1 and Figure 2 As shown, based on Example 1, a display control module 12 is further included. The display control module 12 is in communication with the display terminal 30, and the display control module 12 automatically controls the display brightness of the display terminal 30 through brightness self-adjustment analysis. No manual brightness adjustment of the display terminal is required, which ensures the display effect of the display terminal 30 and has a high degree of intelligence and automation. The specific analysis process of the brightness self-adjustment analysis is as follows:

[0078] The area where the display terminal 30 is located is marked as the target area; the ambient brightness and ambient dust value of the target area are collected; wherein the ambient dust value is a data value indicating the dust concentration in the target area.

[0079] A monitoring facility is provided on the display terminal 30 , and the monitoring facility captures the administrator of the display direction of the display terminal 30 .

[0080] A two-dimensional plane submodule is provided in the display control module 12. The two-dimensional plane submodule marks the straight-line distance between the corresponding manager and the display terminal 30 as the human-machine distance detection value. The center point of the manager and the display terminal 30 is connected by a line segment, and the corresponding line segment is marked as the human-machine line segment, and the acute angle formed between the human-machine line segment and the display terminal 30 is marked as the human-machine angle deviation. It should be noted that when the value of the human-machine angle deviation is 90°, it indicates that the manager is facing the display surface of the display terminal 30, which helps to see the display content clearly. When the value of the human-machine angle deviation is less than 90°, it indicates that the manager is not facing the display surface of the display terminal 30. The smaller the value of the human-machine angle deviation, the more difficult it is for the manager to see the display content clearly. When multiple people are in the display direction at the same time, the display control module 12 can only select a manager with the best angle to adjust the brightness.

[0081] According to the ambient brightness, ambient dust value, human-machine distance detection value and human-machine angle deviation value, the brightness adjustment value is obtained. In this embodiment, the brightness adjustment value is obtained by the following formula:

[0082] ;

[0083] Where LP is the brightness adjustment value, LX is the ambient brightness, LH is the ambient dust level, LR is the human-machine distance detection value, LY is the human-machine angle deviation value, and h1, h2, h3, and h4 are different preset brightness adjustment proportional coefficients. The values ​​of h1, h2, h3, and h4 are all positive numbers, and the larger the brightness adjustment value LP, the more the display brightness of the display terminal 30 needs to be increased.

[0084] The display control module 12 is pre-set with several groups of preset brightness adjustment value ranges, and each group of preset brightness adjustment value ranges corresponds to a group of display brightness.

[0085] The brightness adjustment value is compared with all preset brightness adjustment value ranges one by one, and the display brightness corresponding to the preset brightness adjustment value range containing the corresponding brightness adjustment value is marked as the adjustment brightness, so that the display terminal 30 displays according to the adjustment brightness. This achieves automatic adaptive adjustment of the display brightness of the display terminal 30, making the brightness adjustment more reasonable.

[0086] In one embodiment of the present invention, the display control module 12 evaluates the operating status of the display terminal 30 through display operation analysis to generate a display operation failure signal or a display operation success signal. When a display operation failure signal is generated, the display terminal issues a corresponding warning to remind management personnel to promptly inspect and repair the display terminal to ensure the display performance and diverse functions of the display terminal. The specific analysis process of the display operation analysis is as follows:

[0087] The actual display brightness of the display terminal 30 is collected, and the deviation value of the actual display brightness compared to the set standard brightness is marked as the display brightness detection value. The internal temperature of the display terminal is collected and marked as the display temperature detection value. The vibration data (i.e., vibration amplitude) and the noise data (i.e., noise decibel value) generated by the display terminal 30 during operation are collected and marked as the display vibration detection value and the display noise detection value, respectively.

[0088] The display brightness detection value XL, display temperature detection value XP, display vibration detection value XR and display noise detection value XW are numerically calculated using the formula XF=(rq1*XL+rq2*XP+rq3*XR+rq4*XW) / 4 to obtain the display operation value XF, wherein rq1, rq2, rq3 and rq4 are preset proportional coefficients, and the values ​​of rq1, rq2, rq3 and rq4 are all positive numbers; and the larger the value of the display operation value XF, the worse the display performance of the display terminal.

[0089] The display operation value XF is numerically compared with a preset display operation threshold. If the display operation value XF exceeds the preset display operation threshold, it indicates that the display performance of the display terminal is poor, and a display operation failure signal is generated. If the display operation value XF does not exceed the preset display operation threshold, it indicates that the display performance of the display terminal is good, and a display operation pass signal is generated.

[0090] See also Figure 1 and Figure 2 As shown, in one embodiment of the present invention, when in use, the opening of the needle valve 22 is adjusted to control the leakage amount, the pressure sensor 26 is used to monitor the pipeline pressure, and the flow meter 23 is used to detect the pipeline flow data to determine the leakage amount. The control system 10 controls the pressure-stabilizing pump 21 and the needle valve 22, and receives the detection data of the flow meter 23, the pressure sensor 26 and the gravity sensor 25. The instruction execution detection module 11 in the control system 10 analyzes the control performance of the control system 10 for the pressure-stabilizing pump 21 and the needle valve 22, and when an instruction execution failure signal is generated, the display terminal 30 issues a corresponding early warning to remind management personnel to make reasonable improvement and optimization measures for the control system 10 and the corresponding equipment in a timely manner, thereby ensuring subsequent control performance, and being able to automatically and reasonably adjust the display brightness of the display terminal 30 and promptly feedback abnormal conditions of the display terminal 30, with a high degree of intelligence.
