Description

A method and system for rotating pump station scheduling Technical Field

[0001] This application relates to the field of pump station rotation scheduling technology, specifically to a pump station rotation scheduling method and system. Background Technology

[0002] In intelligent production at fully mechanized mining faces, pump stations, as the power source for key equipment such as hydraulic supports, directly affect the production safety and efficiency of the entire working face through their continuous, stable, and efficient operation. To achieve balanced wear and long-term reliable operation of pump station equipment, a scheduling strategy of rotating multiple pump stations is typically adopted.

[0003] Currently, most common pump station rotation scheduling schemes in the industry are based on simple logic, such as using the cumulative operating time of the equipment as the core rotation criterion, or adopting a fixed "master-standby" pump switching mode. While these traditional methods have achieved the alternating use of equipment to some extent, their inherent limitations are becoming increasingly apparent. First, the rotation conditions are relatively simple, often only considering operating time or simple start / stop commands, failing to fully integrate and utilize multi-dimensional information reflecting the real-time health status of the equipment (such as temperature, current, and pressure), resulting in the system's inability to promptly detect and predict potential failure risks caused by overload, abnormal wear, etc. Second, the rotation logic is rigid and fixed, lacking flexibility. When multiple operating parameters simultaneously become abnormal, the system cannot intelligently determine the processing priority, making it difficult to adapt to the complex and ever-changing dynamic needs of downhole operations. Furthermore, existing solutions typically do not provide convenient parameter customization interfaces, making it difficult for control personnel to flexibly adjust the rotation strategy according to specific equipment characteristics and actual production needs, affecting the system's applicability and operational experience. Summary of the Invention

[0004] The purpose of this application is to provide a pump station rotation scheduling method and system to at least solve the technical problems of insufficient equipment health status perception and poor adaptability to dynamic operating conditions caused by the single rotation conditions and rigid logic in the prior art.

[0005] To solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a method for rotating and scheduling pumping stations, including:

[0007] Obtain the operating status information of the pumping station;

[0008] Determine the rotation dimension corresponding to the running status information;

[0009] The pumping station is scored based on the operational status information and the priority of the rotation dimension corresponding to the operational status information.

[0010] The pump stations are scheduled for rotation based on the rotation score results.

[0011] In some embodiments, the pumping station is scored for rotation based on the operating status information and the priority of the rotation dimension corresponding to the operating status information, including:

[0012] The scoring weights of the rotating dimensions are determined according to their priority order.

[0013] The running status information of different rotation dimensions is normalized, and the status score corresponding to the running status information of each rotation dimension is calculated.

[0014] The rotation score of the pump station is calculated by weighting the status scores and score weights of each rotation dimension.

[0015] In some embodiments, the rotation dimension includes at least one of fault state, current, temperature, and single-run duration, and the rotation score is calculated using the following formula:

[0016] Rotation score = (fault status percentage × fault weight) + (current percentage × current weight) + (temperature percentage × temperature weight) + (single run duration percentage × duration weight).

[0017] In some embodiments, the operation status information of different dimensions is normalized, and a status score corresponding to the operation status information of each rotation dimension is calculated, including:

[0018] If the pumping station is fault-free, the fault percentage of the pumping station is determined to be 0%; if the pumping station issues a fault warning, the fault percentage of the pumping station is determined to be 100%.

[0019] If the current of the pumping station is greater than a preset current threshold, the current percentage of the pumping station is determined to be 100%.

[0020] If the temperature of the pumping station is greater than a preset temperature threshold, the temperature percentage of the pumping station is determined to be 100%.

[0021] If the single run duration of the pumping station is greater than the first preset duration, the percentage of the single run duration of the pumping station is determined to be 100%.

[0022] In some embodiments, the pumping stations are scheduled for rotation based on rotation scoring results, including:

[0023] If the rotation score exceeds a preset rotation trigger threshold, and the duration for which the rotation score exceeds the preset rotation trigger threshold is greater than a second preset duration;

[0024] It has been determined that the pumping stations need to be rotated.

[0025] In some embodiments, determining that multiple pumping stations need to be rotated, and scheduling the pumping stations for rotation based on rotation scoring results, includes:

[0026] Pump station rotation scheduling is carried out according to the rotation score of each pump station.

[0027] If the rotation scores of all the pump stations are the same, the pump station rotation scheduling shall be carried out according to the priority order of each rotation dimension.

[0028] In some embodiments, the method further includes:

[0029] Traverse the list of pump station equipment and determine the available pump stations from the list of pump station equipment;

[0030] If the next pumping station of the currently operating pumping station is not in operation, the pumping station parameters of the next pumping station are within the preset parameter range, and the time interval between the next pumping station and the last rotation is greater than or equal to the minimum rotation interval, then the next pumping station is determined to be an available pumping station.

[0031] Control the currently operating pump station to stop operating, and control the available pump stations to start operating.

[0032] In some embodiments, the method further includes:

[0033] If the currently operating pump station or the available pump station fails to start or stop, the rotation scheduling mode will be switched to manual mode;

[0034] If the currently operating pump station fails to stop, the currently operating pump station is disabled and switched to manual mode; if the currently operating pump station stops successfully but the first available pump station fails to start, the first available pump station is disabled and the pump station equipment list is traversed to find a second available pump station that can be successfully started; if all available pump stations traversed fail to start, the system switches to manual mode.

[0035] In some embodiments, the method further includes:

[0036] During the pump station rotation process, monitor the communication status between the currently operating pump station and the host computer;

[0037] If communication is interrupted, the rotation scheduling mode will be switched to manual mode.

[0059] Example 1

[0060] Figure 1 is a flowchart of the pump station rotation scheduling method according to an embodiment of this application. As shown in Figure 1, the pump station rotation scheduling method provided in this embodiment includes:

[0061] S101: Obtain the operating status information of the pumping station.

[0062] The pump station rotation scheduling method is applied to a pump station rotation scheduling system, which may include a controller and at least one sensor. The sensor is installed at the pump station to monitor the pump station's operating status in real time, acquire the pump station's operating status information, and send it to the controller. The controller is used to analyze and process the operating status information.

[0063] Before step S101, as shown in Figure 2, the controller of the pump station rotation scheduling system opens the data listening and sending ports, and initializes the pump station rotation list, rotation condition list, priority circle weights, and other setting parameters. The system has parameter adjustment functions, and editable parameters include: the rated threshold and priority weight for each rotation judgment dimension; the total score threshold for triggering rotation, delay time h, and minimum rotation interval time t; equipment start timeout time p and stop timeout time q; and the control mode (automatic / manual). In automatic mode, the rotation function is executed automatically; in manual mode, it is operated manually by the central control personnel.

[0064] In step S101, if the pump station is currently in automatic mode, the system collects operating status information in real time through temperature sensors, current sensors, pressure sensors, etc. deployed on each pump station.

[0065] Operational status information refers to a multi-dimensional set of parameters collected in real time by sensors and the pump station control system, comprehensively reflecting the current working condition and health level of the pump station equipment. This includes fault status, current parameters, temperature parameters, and single-run duration. Fault status information includes, but is not limited to, hard faults such as overload alarms, short-circuit alarms, abnormal phase sequence, and communication interruptions, as well as potential early warning information, such as filter blockage warnings. This information is the direct basis for determining whether the equipment should be immediately taken out of service.

[0066] S102: Determine the rotation dimension corresponding to the running status information.

[0067] Specifically, the corresponding rotation dimensions are determined based on the operating status information obtained in step S101. These rotation dimensions include at least one of fault status, current, temperature, and single-run duration. The system primarily evaluates the pump station based on fault status, current parameters, temperature parameters, and single-run duration; therefore, this embodiment sets the aforementioned four rotation dimensions. Fault status directly relates to the bottom line of safe equipment operation; current parameters reflect the real-time load intensity of the equipment; temperature parameters reflect heat accumulation and loss during equipment operation; and single-run duration is used to balance the frequency of equipment use. Each dimension characterizes the health status and risks of the equipment from different perspectives.

[0068] S103: The pump station is scored based on the operation status information and the priority of the rotation dimension corresponding to the operation status information.

[0069] In step S103, the calculation of the rotation score is a systematic quantitative process. Specifically, based on the operating status information and the priority of the rotation dimension corresponding to the operating status information, the pump station is scored for rotation, including:

[0070] S1031: Determine the scoring weight of the rotation dimension according to the priority order of the rotation dimension;

[0071] S1032: Normalize the running status information of different rotation dimensions, and calculate the status score corresponding to the running status information of each rotation dimension;

[0072] S1033: Calculate the rotation score of the pump station by weighting the status scores and score weights of each rotation dimension.

[0073] First, step S1031 assigns specific scoring weights to each dimension according to the preset priority order of the rotation dimensions to reflect the relative importance of different dimensions in the rotation decision. For example, the default weight configuration is as follows: fault status weight 40%, highest priority; current parameter weight 30%; temperature parameter weight 20%; single run duration weight 10%, lowest priority. Users can adjust these weights according to actual needs, but the total must be 100%.

[0074] Next, in step S1032, the original operating status information of different dimensions is normalized and uniformly converted into a status score between 0% and 100%, so that the data of different dimensions are comparable.

[0075] Finally, step S1033 weights the status scores of each dimension with their corresponding score weights to generate a comprehensive rotation score, which can characterize the overall urgency of the pump station needing to be rotated.

[0076] S104: The pumping stations are scheduled for rotation based on the rotation score results.

[0077] After obtaining the rotation score results by performing rotation scoring on each pumping station in step S103, the pumping stations are scheduled for rotation based on the rotation score results.

[0078] Specifically, as shown in Figure 2, step S104 involves rotating and scheduling the pumping stations based on the rotation scoring results, including:

[0079] S1041: If the rotation score exceeds a preset rotation trigger threshold, and the duration for which the rotation score exceeds the preset rotation trigger threshold is greater than a second preset duration;

[0080] S1042: Determine that the pumping station needs to be rotated.

[0081] In step S1041, the system first determines whether the real-time rotation score of the pump station is higher than the preset rotation trigger threshold (e.g., 80 points). At the same time, the system continuously monitors the duration of this over-threshold state and confirms that it is greater than the set second preset duration, which is the delay time.

[0082] In step S1042, the system will only officially mark the pump station as "needing rotation" and include it in the subsequent rotation scheduling queue after the conditions in step S1041 are fully met. This application, by introducing a time-dimensional judgment, effectively filters false alarms caused by instantaneous sensor fluctuations or short-term parameter disturbances, preventing frequent system malfunctions, thereby significantly improving the accuracy of rotation decisions and the stability and reliability of the entire control process.

[0083] This application embodiment implements a rotation scoring algorithm based on multi-dimensional operating status parameters and priority weights, which realizes on-demand rotation scheduling based on the real-time health status of the equipment. It can effectively warn and avoid potential fault risks caused by overload, overheating, etc., and reduce the probability of unplanned downtime.

[0084] In some embodiments, step S1032 involves normalizing the running status information of different dimensions and calculating the status score corresponding to the running status information of each rotation dimension, including:

[0085] S201: If the pumping station is fault-free, determine the fault status percentage of the pumping station as 0%; if the pumping station issues a fault warning, determine the fault status percentage of the pumping station as 100%.

[0086] S202: If the current of the pumping station is greater than the preset current threshold, determine that the current percentage of the pumping station is 100%;

[0087] S203: If the temperature of the pumping station is greater than a preset temperature threshold, the temperature percentage of the pumping station is determined to be 100%.

[0088] S204: If the single running time of the pumping station is greater than the first preset time, the percentage of the single running time of the pumping station is determined to be 100%.

[0089] In this embodiment, the normalization process in step S1032 is a key step to ensure that multi-source heterogeneous data can be weighted and calculated. It converts physical quantities of each dimension into dimensionless state scores through unified rules.

[0090] Specifically, the raw data for each monitoring dimension are converted into a unified percentage format, calculated using the formula: Monitoring Value Percentage = (Actual Monitoring Value / Rated Threshold) × 100%. In step S201, the fault status is a binary variable; the percentage is 0% when there is no fault and 100% when a fault warning is issued. In steps S202, S203, and S204, when the actual monitored values ​​of temperature, current, and single-run duration exceed their corresponding preset thresholds, the percentage is calculated as 100%. This setting preserves the trend of each dimension's parameters within the normal range while ensuring that any parameter exceeding the standard significantly increases the rotation score through a full score, thus achieving sensitive perception and rapid response to abnormal equipment conditions.

[0091] In some embodiments, the formula for calculating the rotation score in step S1033 is:

[0092] Rotation score = (fault status percentage × fault weight) + (current percentage × current weight) + (temperature percentage × temperature weight) + (single run duration percentage × duration weight).

[0093] In this embodiment, the rotation score calculation formula is a weighted summation model determined according to the rotation dimensions. Multi-dimensional parameters reflecting different aspects such as equipment safety (fault status), real-time load (current), operating losses (temperature), and balanced usage (duration) are normalized to percentages and assigned differentiated weights (e.g., the default fault weight is 40%, the highest), and then integrated into a unified comprehensive health index (rotation score). This index not only quantifies the urgency of rotation but also ensures the dominant role of safety-related parameters in rotation decisions through the priority setting of weights, thereby solving the problem of traditional methods having single criteria and being unable to comprehensively assess equipment health status.

[0094] In some embodiments, it is determined that multiple pumping stations need to be rotated. In step S104, the pumping stations are scheduled for rotation based on the rotation scoring results, including:

[0095] S301: Pump station rotation scheduling is carried out according to the rotation score of each pump station.

[0096] S302: If the rotation scores of each pump station are the same, the pump station rotation scheduling shall be carried out according to the priority order of each rotation dimension.

[0097] In step S301, the system sorts all pump stations requiring rotation in descending order according to their calculated rotation scores. The pump station with the highest rotation score indicates the worst overall health status or the strongest urgency for rotation, and therefore receives the highest priority for rotation scheduling. The system will first execute the rotation operation for that pump station.

[0098] In step S302, when two or more pump stations have identical rotation scores, the system uses a preset priority order of rotation dimensions as the discrimination rule. This priority order is predetermined, for example: fault status > current > temperature > single run duration. The system will compare the status of these pump stations with the same score in the highest priority dimension, and the pump station with a worse status in that dimension will be rotated first. If they are still the same in the highest priority dimension, the status of the next lower priority dimension will be compared in turn until the scheduling order is determined.

[0099] In some embodiments, as shown in FIG2, the method further includes:

[0100] S401: Traverse the list of pump station equipment and determine the available pump stations from the list of pump station equipment;

[0101] S402: Wherein, if the next pumping station of the currently operating pumping station is not in operation, the pumping station parameters of the next pumping station are within the preset parameter range, and the time interval between the next pumping station and the last rotation is greater than or equal to the minimum rotation interval, the next pumping station is determined to be an available pumping station.

[0102] S403: Control the currently operating pump station to stop operating and control the available pump station to start operating.

[0103] In step S401, once the system determines that a rotation needs to be performed, it checks each pump station in the pump station equipment list (pump station rotation list) one by one according to the preset pump station equipment list order to filter out pump stations that meet the operating conditions, i.e., "available pump stations". Users can add or delete specific pump station equipment, enable / disable equipment to participate in the rotation, and adjust the equipment order.

[0104] In step S402, determining an "available pump station" requires the following conditions to be met simultaneously: the pump station is not in operation; all parameters (such as temperature, current, and fault status) are within the preset normal threshold range; and the time interval between the pump station's last exit from operation is not less than the minimum rotation interval set by the system. This prevents the equipment from being started and stopped too frequently. Users can add or delete monitoring data items, enable / disable certain rotation conditions, and set logical combinations of monitoring items (simultaneous or any one of these conditions triggers rotation).

[0105] In step S403, after identifying an available pump station, the system sends a command to the controller to first stop the currently running pump station. After the pump station is successfully stopped, the selected available pump station is then started to ensure a smooth transition of power supply.

[0106] In some embodiments, as shown in FIG2, the method further includes:

[0107] S501: If the currently operating pump station or the available pump station fails to start or stop, the rotation scheduling mode will be switched to manual mode;

[0108] S502: Wherein, if the currently operating pump station fails to stop, the currently operating pump station is disabled and switched to manual mode; if the currently operating pump station stops successfully but the first available pump station fails to start, the first available pump station is disabled and the pump station equipment list is traversed to find a second available pump station that can be successfully started; if all available pump stations traversed fail to start, the system switches to manual mode.

[0109] In this embodiment, steps S501 and S502 together constitute a multi-level fault protection mechanism for equipment start-up and shutdown anomalies. When a start-up or shutdown failure occurs during the rotation execution process, the system intelligently adopts differentiated recovery strategies based on the different fault points.

[0110] In step S502, if the currently operating pump station fails to stop, it is identified as a faulty device and immediately disabled. Simultaneously, system control is switched to manual mode, allowing intervention from centralized control personnel, preventing forced operation of the faulty device. If the currently operating pump station stops successfully but the selected first available pump station fails to start, the system automatically disables the failed pump station and continues to traverse the pump station equipment list to find a second available pump station. This second available pump station serves as the next available backup pump station. This automatic retry mechanism maximizes the automated operation of the system. Only when all available pump stations fail to start does the system ultimately degrade to manual mode. This process significantly improves the robustness and continuity of the system under partial equipment failure conditions, ensuring production safety.

[0111] In some embodiments, step S103, the method further includes:

[0112] S601: During the pump station rotation process, monitor the communication status between the currently operating pump station and the host computer;

[0113] S602: If communication is interrupted, switch the rotation scheduling mode to manual mode.

[0114] In step S601, at any stage of the pump station rotation process, the system continuously monitors the connection status of the bidirectional communication link between the host computer (monitoring center) and the currently controlled operating pump station.

[0115] In step S602, when a communication interruption is detected between the host computer and the currently operating pump station (e.g., signal loss, data packet timeout), the system immediately and automatically performs protective operations, switching the control mode of the entire rotation scheduling system from automatic to manual. This effectively prevents the risk of field equipment being in an "out-of-control" state due to control link breakage, ensuring that in extreme cases such as communication failure, system control can be safely and clearly returned to the central control personnel, thereby greatly improving the robustness and safety of the entire control system.

[0116] This application constructs a multi-dimensional quantitative judgment system integrating fault status, current, temperature, and single-run duration, and assigns differentiated weights to drive the priority algorithm, achieving more scientific and forward-looking scheduling decisions and effectively identifying potential risks. Specifically, its scheduling flexibility is significantly enhanced, supporting self-determined configuration of core parameters such as weights and thresholds, and can flexibly adapt to different dynamic operating conditions. In the event of multiple condition conflicts, a strategy combining total score sorting and default priority is adopted to ensure that critical safety factors are responded to first, making conflict handling more reasonable. At the same time, the system integrates multiple fault response mechanisms, including retrying after start / stop failure, disabling faulty equipment, and communication interruption protection, further improving the safety of the operation process and the stability of the overall system.
