The application discloses a remote one-key starting pump station method and system, and can solve the problem that the water pump controlled remotely in the pump station cannot be actually started due to damage although the remote control instruction has been sent. Specifically, after the water pump controller receives the water pump starting instruction, one water pump is started every first preset time length, and the sum of all outlet flow rates is calculated again every second preset time length after one water pump is started each time. The sum of all outlet flow rates obtained by calculation is the common flow value reached by all the started water pumps, and if the sum of all outlet flow rates is greater than or equal to the first target flow value, it is indicated that the started water pump in the pump station reaches the first target flow value required by the water pump starting instruction, and the next water pump does not need to be started.

Description

Technical Field

[0001] This invention relates to the field of pump station management technology, specifically to a method and system for remotely starting a pump station with one click. Background Technology

[0002] A pumping station is a complex of electromechanical equipment and buildings used to pump water from a lower elevation to a higher elevation. The electromechanical equipment mainly consists of water pumps and power units (usually electric motors and diesel engines), while auxiliary equipment includes systems for water filling, supply, drainage, ventilation, compressed air, fuel supply, hoisting, lighting, and fire protection. The buildings include intake structures, pump houses, outlet structures, substations, and administration buildings.

[0003] Pumping stations play an increasingly important role in flood control, drainage, irrigation, water diversion, urban and rural water supply, industrial water supply, navigation, and ecological environment improvement. Currently, to reduce labor costs, remote control is often used to start and stop pumps in these stations. However, pump damage may occur and go undetected. In such cases, although remote control commands may be issued, the pumps that should be started remotely may not actually start due to damage, which is particularly dangerous during the flood season. In other words, existing remote control solutions for pumping stations cannot effectively solve the problem of starting damaged pumps. Summary of the Invention

[0004] The main objective of this invention is to provide a method and system for remotely starting a pumping station with one click, which aims to solve the problem that although a remote control command has been issued, the water pumps in the pumping station that are supposed to be started by remote control may actually not start due to damage.

[0005] The technical solution proposed in this invention is as follows:

[0006] A method for remotely starting a pumping station with one click is applied to a remote one-click pumping station system. The system includes a management terminal, a cloud server, and a pumping station terminal installed at the pumping station. The pumping station terminal includes a pump controller and a flow sensor communicatively connected to the pump controller. Both the pump controller and the management terminal are communicatively connected to the cloud server. The pump controller is used to control the start and stop of each pump in the pumping station. The number of flow sensors is consistent with the number of pumps in the pumping station, and each flow sensor corresponds one-to-one with a pump in the pumping station. The flow sensors are installed at the outlet of the corresponding pump. The method includes:

[0007] The water pump controller acquires the outlet flow rate value of the water pump collected in real time by each of the flow sensors;

[0008] The cloud server obtains the water pump start command input by the management terminal and sends the water pump start command to the water pump controller, wherein the water pump start command includes a first target flow rate value;

[0009] The water pump controller starts one water pump every first preset time interval based on the water pump start command, and after a second preset time interval after starting one water pump, it calculates the sum of all outlet flow values ​​and determines whether the sum of the outlet flow values ​​is greater than or equal to the first target flow value, wherein the second preset time interval is less than the first preset time interval.

[0010] When the sum of the outlet flow rates is greater than or equal to the first target flow rate, the pump controller stops starting the pump and generates a start-up completion command.

[0011] The water pump controller sends the start-up completion command to the cloud server.

[0012] Preferably, the water pump controller starts one water pump every first preset time interval based on the water pump start command, and after a second preset time interval after each water pump is started, calculates the sum of all outlet flow rates and determines whether the sum of the outlet flow rates is greater than or equal to the first target flow rate value, and then further includes:

[0013] When the sum of the outlet flow rates is greater than the first target flow rate, the pump controller marks all started pumps as running pumps.

[0014] The water pump controller reduces the operating power of the running water pump once every first preset time interval, and the power reduction value is a preset power value. After a second preset time interval after each reduction in operating power, the sum of all outlet flow values ​​is calculated to obtain the reduction value of the sum of outlet flow after each reduction in operating power, and it is determined whether the difference between the sum of outlet flow values ​​and the first target flow value is less than the reduction value.

[0015] When the difference between the sum of the outlet flow rates and the first target flow rate is less than the reduction value, the pump controller stops reducing the operating power of the pump.

[0016] Preferably, the water pump controller starts one water pump every first preset time interval based on the water pump start command, and after a second preset time interval after each water pump is started, calculates the sum of all outlet flow rates and determines whether the sum of the outlet flow rates is greater than or equal to the first target flow rate value, and then further includes:

[0017] When the outlet flow rate is equal to the first target flow rate, the pump controller marks all started pumps as running pumps and controls all running pumps to maintain their current operating power.

[0018] Preferably, the start-up completion instruction includes the number of running water pumps; the management terminal includes a display module; the water pump controller sends the start-up completion instruction to the cloud server, and then further includes:

[0019] The cloud server sends the startup completion command to the management terminal;

[0020] The management terminal displays the number of operating water pumps through the display module.

[0021] Preferably, each water pump is assigned a unique water pump number; the method further includes:

[0022] The water pump controller starts one water pump every first preset time interval based on the water pump start command, and after a second preset time interval after starting each water pump, it calculates the sum of all outlet flow values ​​and determines whether the current outlet flow value is consistent with the sum of the outlet flow values ​​before the first preset time interval.

[0023] If so, the pump controller will mark the most recently started pump as a faulty pump;

[0024] The water pump controller sends the pump number of the faulty water pump to the cloud server;

[0025] The cloud server sends the pump number of the faulty water pump to the management terminal.

[0026] Preferably, the cloud server obtains the water pump start command input by the management terminal and sends the water pump start command to the water pump controller, and then further includes:

[0027] The pump controller marks all pumps except the faulty pump as normal pumps.

[0028] The water pump controller obtains the sum of the rated pump water flow values ​​of each normal water pump under full load operation and marks it as the normal maximum flow value.

[0029] The water pump control determines whether the first target flow rate value is greater than or equal to the normal maximum flow rate value;

[0030] If so, the water pump controller controls all water pumps to start and sends the normal maximum flow rate value to the cloud server;

[0031] The cloud server sends the normal maximum traffic value to the management terminal.

[0032] Preferably, the pump control determines whether the first target flow rate value is greater than or equal to the normal maximum flow rate value, and then further includes:

[0033] If not, the pump controller starts one pump every first preset time interval based on the pump start command, and after a second preset time interval after each pump is started, calculates the sum of all outlet flow values, and determines whether the sum of the outlet flow values ​​is greater than the first target flow value, and then proceeds with the following steps.

[0034] Preferred options also include:

[0035] When all water pumps have started and the sum of the outlet flow rates is still less than the first target flow rate, the water pump controller controls all water pumps to start.

[0036] Preferred options also include:

[0037] The cloud server obtains the flow reduction instruction input by the management terminal and sends the flow reduction instruction to the water pump controller, wherein the flow reduction instruction includes a second target flow value;

[0038] The water pump controller acquires the outlet flow rate value corresponding to each of the operating water pumps and marks it as the current flow rate value;

[0039] The pump controller calculates the number of pumps to be shut down based on the current flow rate and the second target flow rate, wherein the product of the number of pumps to be shut down and the current flow rate is greater than the second target flow rate;

[0040] The water pump controller controls the number of water pumps to be shut down among the operating water pumps to stop working.

[0041] This invention also proposes a remote one-click start pumping station system, which is applied to a remote one-click start pumping station method as described in any of the above-mentioned methods. The system includes a management terminal, a cloud server, and a pumping station terminal located at the pumping station. The pumping station terminal includes a pump controller and a flow sensor communicatively connected to the pump controller. Both the pump controller and the management terminal are communicatively connected to the cloud server. The pump controller is used to control the start and stop of each pump in the pumping station. The number of flow sensors is consistent with the number of pumps in the pumping station, and each flow sensor corresponds one-to-one with a pump in the pumping station. The flow sensors are located at the outlet of the corresponding pump.

[0042] The above technical solution can achieve the following beneficial effects:

[0043] The remote one-button start method for pump stations proposed in this invention can solve the problem that although a remote control command has been issued, the pumps in the pump station that are supposed to be started by remote control may not actually start due to damage. Specifically, after receiving the pump start command, the pump controller starts one pump every first preset time interval. After each pump is started, a second preset time interval is elapsed, and the sum of all outlet flow rates is calculated again. The calculated sum of all outlet flow rates is the common flow rate value achieved by all currently started pumps. If this sum of all outlet flow rates is greater than or equal to the first target flow rate value, it means that the pumps currently started in the pump station have reached the first target flow rate value required by the pump start command, and no further target flow rate is needed. To continue starting the next pump, even if a pump malfunctions and stops working, the final startup effect will not be affected. This is because the pump controller will start the pumps in the pumping station sequentially. If a malfunctioning pump fails to increase the outlet flow rate after starting, the next pump will be started until the sum of all outlet flows is greater than or equal to the first target flow rate value. In other words, this solution determines whether the pumping station is successfully remotely controlled based on whether the final pump flow rate reaches the user-set first target value, rather than on whether the pumps accept the start command. This results in higher accuracy and better control. It effectively solves the problem that existing remote control solutions for pumping stations cannot effectively solve the startup problem of damaged pumps. Attached Figure Description

[0044] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the structures shown in these drawings without creative effort.

[0045] Figure 1 This is a flowchart of the first embodiment of a remote one-button start-up method for a pumping station proposed in this invention. Detailed Implementation

[0046] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0047] This invention proposes a method and system for remote one-button start-up of a pumping station.

[0048] As attached Figure 1As shown, in the first embodiment of the remote one-click start pumping station method proposed in this invention, the remote one-click start pumping station method is applied to a remote one-click start pumping station system; the system includes a management terminal, a cloud server, and a pumping station terminal set up at the pumping station; the pumping station terminal includes a water pump controller and a flow sensor communicatively connected to the water pump controller; both the water pump controller and the management terminal are communicatively connected to the cloud server; the water pump controller is used to control the start and stop of each water pump in the pumping station; the number of flow sensors is consistent with the number of water pumps in the pumping station, and the flow sensors correspond one-to-one with the water pumps in the pumping station; the flow sensors are set at the outlet of the corresponding water pump; this embodiment includes the following steps:

[0049] Step S110: The water pump controller acquires the outlet flow rate value of the water pump collected in real time by each of the flow sensors.

[0050] Step S120: The cloud server obtains the water pump start command input by the management terminal and sends the water pump start command to the water pump controller, wherein the water pump start command includes a first target flow rate value.

[0051] Specifically, the first target flow rate value here is the flow rate that the user inputs to be achieved after starting the water pump, for example, 3000 m³ / h. 3 / h.

[0052] Step S130: The water pump controller starts one water pump every first preset time interval (e.g., 10 seconds) based on the water pump start command, and after a second preset time interval (e.g., 5 seconds) after each water pump is started, it calculates the sum of all outlet flow values ​​and determines whether the sum of the outlet flow values ​​is greater than or equal to the first target flow value, wherein the second preset time interval is less than the first preset time interval.

[0053] Specifically, after receiving the pump start command, the pump controller starts one pump every 10 seconds, and calculates the sum of all outlet flow rates 5 seconds after each pump starts (because under normal circumstances, the flow sensor at the pump outlet will detect the flow rate 5 seconds after the pump starts). In other words, the sum of all outlet flow rates calculated 5 seconds after each pump starts is the common flow rate value reached by all the pumps that have started. If this sum of all outlet flow rates is greater than or equal to the first target flow rate value, it means that the pumps currently started in the pumping station have reached the first target flow rate value required by the pump start command, and the next pump will not be started.

[0054] Step S140: When the sum of the outlet flow rates is greater than or equal to the first target flow rate, the pump controller stops starting the pump and generates a start-up completion command.

[0055] Step S150: The water pump controller sends the start-up completion command to the cloud server.

[0056] The remote one-button start method for pump stations proposed in this invention can solve the problem that although a remote control command has been issued, the pumps in the pump station that are supposed to be started by remote control may not actually start due to damage. Specifically, after receiving the pump start command, the pump controller starts one pump every first preset time interval. After each pump is started, a second preset time interval is elapsed, and the sum of all outlet flow rates is calculated again. The calculated sum of all outlet flow rates is the common flow rate value achieved by all currently started pumps. If this sum of all outlet flow rates is greater than or equal to the first target flow rate value, it means that the pumps currently started in the pump station have reached the first target flow rate value required by the pump start command, and no further target flow rate is needed. To continue starting the next pump, even if a pump malfunctions and stops working, the final startup effect will not be affected. This is because the pump controller will start the pumps in the pumping station sequentially. If a malfunctioning pump fails to increase the outlet flow rate after starting, the next pump will be started until the sum of all outlet flows is greater than or equal to the first target flow rate value. In other words, this solution determines whether the pumping station is successfully remotely controlled based on whether the final pump flow rate reaches the user-set first target value, rather than on whether the pumps accept the start command. This results in higher accuracy and better control. It effectively solves the problem that existing remote control solutions for pumping stations cannot effectively solve the startup problem of damaged pumps.

[0057] In a second embodiment of a remote one-click pump station start method proposed in this invention, based on the first embodiment, step S130 is followed by the following steps:

[0058] Step S210: When the sum of the outlet flow rates is greater than the first target flow rate, the pump controller marks all started pumps as running pumps.

[0059] Specifically, if the sum of the outlet flow rates is greater than the first target flow rate, it means that the sum of the outlet flow rates generated by each operating pump exceeds the first target flow rate and needs to be reduced.

[0060] Step S220: The water pump controller reduces the operating power of the running water pump once every first preset time interval. The power reduction value is a preset power value (e.g., 0.5 kW). After a second preset time interval after each power reduction, the sum of all outlet flow values ​​is calculated to obtain the reduction value of the sum of outlet flow values ​​after each power reduction. The controller then determines whether the difference between the sum of outlet flow values ​​and the first target flow value is less than the reduction value.

[0061] Specifically, the water pump controller reduces the operating power of the water pump by 0.5 kW every 10 seconds. Five seconds after each power reduction, the controller recalculates the sum of the outlet flow rates to obtain the decrease in the sum of the outlet flow rates after each power reduction (this decrease is the reduction in the sum of the outlet flow rates caused by each 0.5 kW reduction in the operating power of the water pump). The controller then determines whether the difference between the sum of the outlet flow rates and the first target flow rate is less than the decrease.

[0062] Step S230: When the difference between the sum of the outlet flow rates and the first target flow rate is less than the reduction value, the pump controller stops reducing the operating power of the pump.

[0063] Specifically, when the difference between the sum of the outlet flow values ​​and the first target flow value is less than the reduction value, it means that the sum of the outlet flow values ​​has been reduced to the closest to the first target flow value (further reduction would cause the sum of the outlet flow values ​​to be less than the first target flow value, which does not meet the user's original intention). Therefore, the pump controller will no longer reduce the operating power of the pump (i.e., the pump will maintain the current operating power).

[0064] In the third embodiment of the remote one-button start-up method for a pumping station proposed in this invention, based on the second embodiment, step S130 is followed by the following steps:

[0065] Step S310: When the outlet flow rate value is equal to the first target flow rate value, the pump controller marks all started pumps as running pumps and controls all running pumps to maintain the current operating power.

[0066] Specifically, when the sum of the outlet flow rates equals the first target flow rate, it means that the pumps in the current pumping station are just meeting the user's needs. In this case, the pump controller controls all the operating pumps to maintain their current operating power.

[0067] In the fourth embodiment of the remote one-click start method for a pump station proposed in this invention, based on the second embodiment, the start-up completion command includes the number of running water pumps; the management terminal includes a display module (e.g., a display screen); step S150, followed by the following steps:

[0068] Step S410: The cloud server sends the startup completion command to the management terminal.

[0069] Step S420: The management terminal displays the number of operating water pumps through the display module.

[0070] Specifically, the number of operating water pumps is displayed on the management terminal's display module, allowing managers to have a more detailed understanding of the pump station's operating status.

[0071] In the fifth embodiment of the remote one-button start method for a pumping station proposed in this invention, based on the first embodiment, each water pump is assigned a unique water pump number; this embodiment also includes the following steps:

[0072] Step S510: The water pump controller starts one water pump every first preset time interval based on the water pump start command, and after a second preset time interval after starting one water pump, it calculates the sum of all outlet flow values ​​and determines whether the outlet flow value at the current moment is consistent with the sum of the outlet flow values ​​before the first preset time interval.

[0073] Specifically, after each pump is started, the sum of all outlet flow values ​​is calculated every 5 seconds, and it is determined whether the current outlet flow value is consistent with the sum of outlet flow values ​​before the first preset time. If they are consistent, it means that the pump started most recently did not increase the sum of outlet flow values, which means that the pump started most recently did not successfully pump water, and is therefore a faulty pump.

[0074] If so, proceed to step S520: the pump controller marks the most recently started pump as a faulty pump.

[0075] Step S530: The water pump controller sends the pump number of the faulty water pump to the cloud server.

[0076] Step S540: The cloud server sends the pump number of the faulty water pump to the management terminal.

[0077] Specifically, this embodiment provides a specific solution for determining the faulty water pump.

[0078] In the sixth embodiment of the remote one-button start-up method for a pumping station proposed in this invention, based on the fifth embodiment, step S120 is followed by the following steps:

[0079] Step S610: The water pump controller marks the remaining water pumps, except for the faulty water pump, as normal water pumps.

[0080] Step S620: The water pump controller obtains the sum of the rated pump water flow values ​​of each normal water pump under full load operation and marks it as the normal maximum flow value.

[0081] Specifically, the normal maximum flow rate here is the sum of the maximum outlet flow rates that all the pumps in the pumping station can achieve when starting at full load (that is, the maximum pumping flow rate of the pumping station).

[0082] Step S630: The water pump control determines whether the first target flow rate value is greater than or equal to the normal maximum flow rate value.

[0083] If so, proceed to step S640: the water pump controller controls all water pumps to start and sends the normal maximum flow value to the cloud server.

[0084] Specifically, if the first target flow rate is greater than or equal to the normal maximum flow rate, it means that the first target flow rate entered by the user exceeds or is exactly equal to the maximum pumping flow rate of the pumping station, and all the pumps in the pumping station will be started directly.

[0085] Step S650: The cloud server sends the normal maximum traffic value to the management terminal.

[0086] In the seventh embodiment of the remote one-button start-up method for a pumping station proposed in this invention, based on the sixth embodiment, after step S630, the following steps are further included:

[0087] If not, proceed to step S130 and the subsequent steps.

[0088] Specifically, if the first target flow rate is less than the normal maximum flow rate, it means that the pumping station does not need to start all the water pumps, and the water pumps are started normally in sequence according to the method of the first embodiment.

[0089] In the eighth embodiment of the remote one-button start-up method for a pumping station proposed in this invention, based on the first embodiment, this embodiment further includes the following steps:

[0090] Step S810: When all water pumps have been started and the sum of the outlet flow rates is still less than the first target flow rate, the water pump controller controls all water pumps to start.

[0091] Specifically, if it is not determined whether there is a faulty pump in the pumping station (for example, when the pumping station is remotely started for the first time and the first target flow value is less than the normal maximum flow value of the pumping station), the pumps in the pumping station can only be started sequentially. If all the pumps have been started and the sum of the outlet flow values ​​is still less than the first target flow value, it means that there is indeed a faulty pump in the pumping station. Therefore, in order to meet the pumping demand, the pump controller controls all the pumps to start.

[0092] In the ninth embodiment of the remote one-button start-up method for a pumping station proposed in this invention, based on the second embodiment, this embodiment further includes the following steps:

[0093] Step S910: The cloud server obtains the flow reduction instruction input by the management terminal and sends the flow reduction instruction to the water pump controller, wherein the flow reduction instruction includes a second target flow value.

[0094] Specifically, the second target flow rate value here is the value at which the user wants to reduce the pump water flow rate (e.g., 1000m³ / h). 3 / h).

[0095] Step S920: The water pump controller obtains the outlet flow rate value corresponding to each of the operating water pumps and marks it as the current flow rate value.

[0096] Specifically, in this embodiment, the outlet flow rate of each operating water pump is set to be the same, which is the current flow rate (e.g., 300m³). 3 / h).

[0097] Step S930: The pump controller calculates the number of pumps to be shut down based on the current flow rate and the second target flow rate, wherein the product of the number of pumps to be shut down and the current flow rate is greater than the second target flow rate.

[0098] The specific formula for calculating the number of water pumps to be shut down is as follows:

[0099]

[0100] In the formula, S d Q1 represents the number of water pumps to be shut down; Q2 represents the second target flow rate value, in m³ / s. 3 / S;Q d The current flow rate value is expressed in milliseconds (m). 3 / S.

[0101] Specifically, in this embodiment, the number of pumps to be shut down is 4. That is, 4 operating pumps need to be shut down. In this embodiment, the product of the number of pumps to be shut down and the current flow rate is set to be greater than the second target flow rate. This ensures that more pumps can rest, and the missing pumping flow can be made up by increasing the operating power of the remaining operating pumps.

[0102] Step S940: The water pump controller controls the number of water pumps to be shut down among the operating water pumps to stop working.

[0103] In the tenth embodiment of the remote one-button start-up method for a pumping station proposed in this invention, based on the ninth embodiment, after step S940, the following steps are further included:

[0104] Step S1010: The water pump control subtracts the second target flow value from the first target flow value to obtain the third target flow value.

[0105] Specifically, since the product of the number of pumps to be shut down and the current flow rate is greater than the second target flow rate, it is necessary to increase the operating power of the remaining pumps to ensure that the pumping station's water flow rate is closer to the third target flow rate.

[0106] Step S1020: The water pump controller increases the operating power of the running water pump once every first preset time interval. The power increase value is a preset power value (e.g., 0.5 kW). After a second preset time interval after each power increase, the sum of all outlet flow values ​​is calculated to obtain the increase value of the sum of outlet flow values ​​after each power increase. The difference between the sum of outlet flow values ​​and the third target flow value is determined to be less than the increase value.

[0107] Specifically, the pump controller increases the operating power of the pump every 10 seconds by 0.5 kW each time. Five seconds after each power increase, the sum of the outlet flow values ​​is recalculated to obtain the increase in the sum of the outlet flow values ​​after each power decrease (this increase is the increase in the sum of the outlet flow values ​​caused by each 0.5 kW power increase of the pump). The controller then determines whether the difference between the sum of the outlet flow values ​​and the third target flow value is less than the increase.

[0108] Step S1030: When the difference between the sum of the outlet flow rates and the third target flow rate is less than the increase value, the pump controller stops increasing the operating power of the pump.

[0109] Specifically, when the difference between the sum of the outlet flow values ​​and the third target flow value is less than the increment, it means that the sum of the outlet flow values ​​has been increased to be closest to the third target flow value (continuing to increase it will cause the sum of the outlet flow values ​​to be greater than the third target flow value, which does not meet the user's original intention). Therefore, the pump controller will no longer continue to reduce or increase the operating power of the pump (i.e., the pump maintains the current operating power).

[0110] This invention also proposes a remote one-click start pumping station system. This system is applied to a remote one-click start pumping station method as described in any of the above-mentioned methods. The system includes a management terminal, a cloud server, and a pumping station terminal installed at the pumping station. The pumping station terminal includes a pump controller and a flow sensor communicatively connected to the pump controller. Both the pump controller and the management terminal are communicatively connected to the cloud server. The pump controller is used to control the start and stop of each pump in the pumping station. The number of flow sensors is consistent with the number of pumps in the pumping station, and each flow sensor corresponds one-to-one with a pump in the pumping station. The flow sensors are installed at the outlet of the corresponding pump.
