Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, and specifically to a method, controller and pumping equipment for predicting the remaining operational status of pumping equipment. Background Technology

[0002] Currently, diesel engines remain the mainstream power source in the construction machinery industry, making diesel consumption a key variable of concern for construction workers. However, vehicle fuel tanks have limited capacity, and diesel consumption is enormous when the workload is large. If workers are not careful about the remaining fuel level, it is easy to run out of fuel and render the vehicle immobile. In such situations, the only option is to call for refueling with bottled fuel, which significantly delays the construction schedule and also poses certain safety hazards.

[0003] To address this, existing technologies display the remaining fuel percentage on the dashboard inside the driver's cab and provide low fuel level alerts, allowing operators to be aware of the remaining fuel situation. However, in the field of pumping equipment, this technology still has the following drawbacks:

[0004] 1. The fuel consumption of pumping equipment changes dynamically with the pumping conditions, and it is difficult for operators to predict the next operation of the equipment based solely on the percentage of remaining fuel.

[0005] 2. Construction workers cannot estimate how much fuel percentage needs to be left to ensure the pumping equipment can reach the nearest gas station. Summary of the Invention

[0033] In this embodiment of the application, the method further includes:

[0055] Figure 1 This is a flowchart illustrating a method for predicting the remaining operational availability of pumping equipment, provided as an embodiment of this application. Figure 1 As shown in the figure, this application provides a method for predicting the remaining operational status of a pumping device, applied to the controller of the pumping device. The method may include the following steps:

[0056] Step 101: During the operation of the pumping equipment, determine the remaining oil volume of the pumping equipment at the current moment;

[0057] Step 102: Obtain the fuel consumption of the pumping equipment.

[0058] Step 103: Compare the fuel consumption with the remaining fuel.

[0059] Step 104: If the remaining fuel is greater than the fuel consumption during driving, determine the fuel consumption parameters of the pumping equipment at the current moment;

[0060] Step 105: Determine the remaining pumpable volume and / or remaining working time of the pumping equipment under the current operating conditions based on the driving fuel consumption, remaining fuel volume, and fuel consumption parameters.

[0061] In this embodiment, the remaining operational status of the pumping equipment refers to the remaining operational time and remaining pumpable volume of the pumping equipment given the current remaining fuel level. The remaining fuel level is the amount of fuel remaining in the pumping equipment at the current moment, and the fuel consumption refers to the amount of fuel consumed by the pumping equipment to travel from the current construction site to the nearest gas station. To determine the remaining operational status of the pumping equipment at the current moment, the controller can determine the remaining fuel level and fuel consumption of the pumping equipment at the current moment.

[0062] In one example, during a complete construction process, the fuel quantity A0 of the pumping equipment before departure and the fuel quantity A1 after reaching the construction site can be recorded. The difference between the total fuel quantity A1 and the total fuel quantity A0 is determined as the driving fuel consumption of the pumping equipment, i.e., driving fuel consumption Q = A1 - A0.

[0063] In another example, the historical fuel consumption speed of the pumping equipment during its operation can be obtained, the average fuel consumption speed can be calculated based on the historical fuel consumption speed, and the distance from the current construction site to the nearest gas station can be obtained. The fuel consumption of the pumping equipment can then be calculated based on the distance and the average fuel consumption speed.

[0064] Furthermore, the controller can compare the pumping equipment's operating fuel consumption with the remaining fuel at the current moment. If the remaining fuel at the current moment is greater than the operating fuel consumption, it indicates that the remaining fuel of the pumping equipment can support continued operation. To determine the remaining operational capability of the pumping equipment under the current operating conditions, the controller can determine the pumping equipment's fuel consumption parameters at the current moment. In one example, the pumping equipment's fuel consumption parameters may include target pumping fuel consumption rate, target pumping speed, idle ratio, and idle fuel consumption rate; where, target pumping fuel consumption rate refers to the amount of fuel consumed by the pumping equipment per cubic meter of concrete pumped under the current operating conditions, target pumping speed refers to the amount of concrete pumped by the pumping equipment per hour under the current operating conditions, idle ratio refers to the proportion of the pumping equipment's idling time from the start of construction to the current moment, and idle fuel consumption rate refers to the amount of fuel consumed by the pumping equipment per hour of idling.

[0065] Furthermore, based on the driving fuel consumption, remaining fuel volume, and fuel consumption parameters, the remaining pumpable volume and / or remaining operating time of the pumping equipment under the current operating conditions can be calculated. The remaining pumpable volume refers to the amount of concrete that the pumping equipment can pump at the current moment, assuming it can reach the nearest gas station. The remaining operating time refers to the duration of operation that the pumping equipment can maintain under the current operating conditions, assuming it can reach the nearest gas station.

[0066] The above technical solution determines the remaining oil level and fuel consumption of the pumping equipment during operation. It then compares the fuel consumption with the remaining oil level; if the remaining oil level is greater than the fuel consumption, the current fuel consumption parameters are determined. Finally, based on the fuel consumption, remaining oil level, and fuel consumption parameters, the remaining pumpable volume and / or remaining working time under the current operating conditions are determined. This application enables the pumping equipment to determine its remaining pumpable volume and remaining working time during operation, allowing technicians to accurately grasp the remaining operational status of the pumping equipment, thus improving construction efficiency and safety.

[0067] Figure 2 This is a schematic diagram of a pumping device provided in an embodiment of this application. Figure 2 As shown in this embodiment, the controller 100 can communicate with the mobile terminal 200, and the method further includes:

[0068] Send the remaining pumpable volume and / or remaining working time to the mobile terminal 200.

[0069] Specifically, existing technology can only display the percentage of remaining fuel or a low fuel warning message on the driver's cab instrument panel. If the operator uses remote control to operate the pumping equipment, they will leave the cab and cannot promptly check the remaining fuel status displayed on the instrument panel. To address this, the controller 100 in this embodiment can also communicate with the mobile terminal 200. The controller 100 can send the calculated remaining working time and remaining pumpable volume of the pumping equipment under the current operating conditions to the mobile terminal 200. In this way, the operator can obtain real-time information about the remaining working status of the pumping equipment through the mobile terminal 200, and then control the pumping equipment based on this information, which helps improve construction efficiency and safety.

[0070] In this embodiment of the application, the method further includes:

[0071] If the remaining fuel level is less than or equal to the fuel consumption, a prompt signal is sent to the mobile terminal.

[0072] In one example, if the current remaining fuel level of the pumping equipment is equal to the amount of fuel used for driving, it means that the current remaining fuel level of the pumping equipment is only enough to drive to the nearest gas station for refueling. At this time, the controller can send a prompt signal to the mobile terminal to remind the operator to stop the operation and control the construction equipment to reach the nearest gas station for refueling.

[0073] In another example, if the remaining fuel level of the pumping equipment is less than the driving fuel level, it means that the remaining fuel level is insufficient to propel the equipment to the nearest gas station. In this case, the controller sends a warning signal to the mobile terminal to remind the operator that the fuel level is low. Upon receiving this warning, the operator can take appropriate action based on the actual construction situation.

[0074] It should be noted that the form of the above prompts can be freely set, such as outputting text prompts, voice prompts, and signal light prompts.

[0075] In this embodiment of the application, the fuel consumption parameters of the pumping equipment include the target pumping fuel consumption rate, the target pumping speed, the idle ratio, and the idle fuel consumption rate. Determining the remaining pumpable volume and / or remaining working time of the pumping equipment under the current operating conditions based on the driving fuel consumption, remaining fuel volume, and fuel consumption parameters includes:

[0076] determining the difference between the remaining fuel amount and the driving fuel consumption amount as the remaining working fuel amount of the pumping equipment;

[0077] determining the remaining pumpable volume and / or remaining operable duration according to the remaining working fuel amount, target pumping fuel consumption rate, target pumping speed, idling ratio and idling fuel consumption rate.

[0078] Specifically, the remaining pumpable volume of the pumping equipment refers to the volume of concrete that can be pumped by the pumping equipment with the remaining fuel amount of the pumping equipment at the current moment under the current working condition on the premise that the pumping equipment can drive to the nearest gas station. The remaining operable duration of the pumping equipment refers to the operable duration that can be operated by the pumping equipment under the current working condition with the remaining fuel amount of the pumping equipment at the current moment on the premise that the pumping equipment can drive to the nearest gas station. In the embodiment of the present application, when the current remaining fuel amount of the pumping equipment is greater than the driving fuel consumption amount, the difference between the remaining fuel amount and the driving fuel consumption amount may be determined as the remaining working fuel amount of the pumping equipment under the current working condition, and the remaining working fuel amount is the fuel amount that can be used for pumping operation.

[0079] In the embodiment of the present application, during the construction of the pumping equipment, the total fuel amount can be obtained by adding the operation fuel consumption during the pumping operation of the pumping equipment and the idling fuel consumption during idling, then based on the above relationship, according to the remaining operation fuel amount of the pumping equipment at the current moment, relational expression (1) can be constructed:[

[0080]

[0081] wherein, C is the remaining pumpable volume, unit: m 3 , cubic meter; H is the remaining operable duration, unit: h, hour; Q is the remaining working fuel amount, unit: L, liter; T is the idling ratio (0<T<1); S is the target pumping speed, unit: m 3 / h, cubic meter per hour; F is the target pumping fuel consumption rate, unit: L / m 3 , liter per cubic meter; D is the idling fuel consumption rate, unit: L / h, liter per hour; η is the fuel consumption coefficient of boom outriggers. In one example, considering that the pumping equipment has a certain working time of boom outriggers besides the pumping and idling processes, η is the consumption coefficient of fuel consumption of boom outriggers. Since the fuel consumption of the boom outriggers accounts for a relatively low proportion of the fuel consumed in a single construction process, the fuel consumption of the boom outriggers is not included in the prediction system, and the value of η is less than 1 and greater than 0.9.

[0082] The calculation formulas for the remaining operable duration and remaining pumpable volume of the pumping equipment under the current working condition can be respectively derived according to the above formula (1).

[0083] In the embodiment of the present application, the remaining pumpable volume satisfies formula (2):

[0084]

[0085] The remaining workable time satisfies formula (3):

[0086]

[0087] Where C is the remaining pumpable volume, H is the remaining working time, Q is the remaining working oil volume, T is the idle speed ratio, S is the target pumping speed, F is the target pumping oil consumption rate, D is the idle oil consumption rate, and η is the boom outrigger oil consumption coefficient.

[0088] In this embodiment of the application, when the pumping equipment is in the process of pumping operation, the current idle speed ratio of the pumping equipment can be determined by the ratio of the idle time of the pumping equipment from the start time of operation to the current time to the current total operation time.

[0089] In this embodiment, if the current time is the start time of the pumping operation, historical construction data of the pumping equipment can be obtained, and the average pumping fuel consumption rate, average pumping speed, idle ratio, and idle fuel consumption rate of the pumping equipment in a single historical construction process can be obtained based on the historical construction data. The average pumping fuel consumption rate, average pumping speed, idle ratio, and idle fuel consumption rate are then used as fuel consumption parameters of the pumping equipment at the start time of the operation to calculate the remaining working time and remaining pumpable volume of the pumping equipment at the start time of the operation.

[0090] In this embodiment of the application, determining the oil consumption parameters of the pumping equipment at the current moment includes:

[0091] Obtain multiple pumping oil consumption rates and multiple pumping speeds corresponding to multiple pumping cycles;

[0092] The average of multiple pumping oil consumption rates is determined as the target pumping oil consumption rate;

[0093] The average of multiple pumping speeds is determined as the target pumping speed;

[0094] Among them, multiple pumping cycles include the current pumping cycle.

[0095] Specifically, the target pumping oil consumption rate and target pumping speed can be determined by averaging the multiple pumping oil consumption rates and multiple pumping speeds corresponding to multiple pumping cycles.

[0096] In one specific embodiment, taking three pumping cycles as an example, the target pumping oil consumption rate and target pumping speed (F0, S0) of the current pumping cycle, as well as the previous pumping cycle (F1, S1) and the pumping cycle before that (F2, S2) of the current pumping cycle are obtained. Then the target pumping oil consumption rate and target pumping speed satisfy formulas (4) and (5) respectively:

[0097]

[0098]

[0099] Where S is the target pumping speed and F is the target pumping oil consumption speed.

[0100] This can improve the accuracy of the prediction results.

[0101] In this embodiment of the application, determining the oil consumption parameters of the pumping equipment at the current moment includes:

[0102] Obtain the historical pumping dataset of the pumping equipment;

[0103] Construct a load spectrum list for pumping equipment based on historical pumping datasets;

[0104] Obtain the current pumping pressure of the pumping equipment at the current moment;

[0105] Based on the current pumping pressure, the target pumping oil consumption rate and the target pumping speed are determined by the load spectrum list.

[0106] Figure 3 This is a schematic diagram of the load spectrum of a pumping device according to a specific embodiment of this application. Figure 3 As shown, the controller can construct a load spectrum list regarding "pumping pressure - pumping speed - pumping fuel consumption rate" based on the historical dataset of the pumping equipment. Furthermore, the controller can obtain the current pumping pressure of the pumping equipment at the current moment, and based on the current pumping pressure, derive the target pumping fuel consumption rate and target pumping speed of the pumping equipment from the load spectrum list. This load spectrum list contains all historical data for the pumping equipment, and its use can improve the accuracy of prediction results.

[0111] Obtain the fuel consumption of the pumping equipment;

[0112] Compare fuel consumption during driving with remaining fuel;

[0113] Determine the fuel consumption parameters of the pumping equipment at the current moment when the remaining fuel level is greater than the fuel consumption during driving.

[0114] The remaining pumpable volume and / or remaining operating time of the pumping equipment under the current operating conditions are determined based on the driving fuel consumption, remaining fuel volume, and fuel consumption parameters.

[0115] In this embodiment of the application, the fuel consumption parameters of the pumping equipment include the target pumping fuel consumption rate, the target pumping speed, the idle ratio, and the idle fuel consumption rate. Determining the remaining pumpable volume and / or remaining working time of the pumping equipment under the current operating conditions based on the driving fuel consumption, remaining fuel volume, and fuel consumption parameters includes:

[0116] The difference between the remaining oil level and the fuel consumption during driving is determined as the remaining working oil level of the pumping equipment;

[0117] The remaining pumpable volume and / or remaining working time are determined based on the remaining working oil volume, target pumping oil consumption rate, target pumping speed, idle ratio, and idle oil consumption rate.

[0118] In this embodiment of the application, the remaining pumpable volume satisfies formula (2):

[0119]

[0120] The remaining workable time satisfies formula (3):

[0121]

[0122] Where C is the remaining pumpable volume, H is the remaining working time, Q is the remaining working oil volume, T is the idle speed ratio, S is the target pumping speed, F is the target pumping oil consumption rate, D is the idle oil consumption rate, and η is the boom outrigger oil consumption coefficient.

[0123] Furthermore, the processor 120 can also be configured to:

[0124] Obtain multiple pumping oil consumption rates and multiple pumping speeds corresponding to multiple pumping cycles;

[0125] The average of multiple pumping oil consumption rates is determined as the target pumping oil consumption rate;

[0126] The average of multiple pumping speeds is determined as the target pumping speed;

[0127] Among them, multiple pumping cycles include the current pumping cycle.

[0128] Furthermore, the processor 120 can also be configured to:

[0129] Obtain the historical pumping dataset of the pumping equipment;

[0130] Construct a load spectrum list for pumping equipment based on historical pumping datasets;

[0131] Obtain the current pumping pressure of the pumping equipment at the current moment;

[0132] Based on the current pumping pressure, the target pumping oil consumption rate and the target pumping speed are determined by the load spectrum list.

[0133] Furthermore, the processor 120 can also be configured to:

[0134] Send the remaining pumpable volume and / or remaining working time to the mobile terminal.

[0135] Furthermore, the processor 120 can also be configured to:

[0136] If the remaining fuel level is less than or equal to the fuel consumption, a prompt signal is sent to the mobile terminal.

[0137] The above technical solution determines the remaining oil level and fuel consumption of the pumping equipment during operation. It then compares the fuel consumption with the remaining oil level; if the remaining oil level is greater than the fuel consumption, the current fuel consumption parameters are determined. Finally, based on the fuel consumption, remaining oil level, and fuel consumption parameters, the remaining pumpable volume and / or remaining working time under the current operating conditions are determined. This application enables the pumping equipment to determine its remaining pumpable volume and remaining working time during operation, allowing technicians to accurately grasp the remaining operational status of the pumping equipment, thus improving construction efficiency and safety.

[0141] In this application, the pumping equipment includes a controller 100 and a mobile terminal 200, which can communicate with the controller 100. Existing technology can only display the percentage of remaining fuel or a low fuel warning message on the driver's cab instrument panel. If the operator uses remote control to operate the pumping equipment, they will leave the cab and cannot promptly obtain the remaining fuel status displayed on the instrument panel. Therefore, in this embodiment, the controller 100 can also communicate with the mobile terminal 200. The controller 100 can send the calculated remaining working time and remaining pumpable volume of the pumping equipment under the current operating conditions to the mobile terminal 200. Thus, the operator can obtain real-time information about the remaining working status of the pumping equipment through the mobile terminal 200, and then control the pumping equipment based on this information, which helps improve construction efficiency and safety.
