[0030] Figure 1 A flow chart of a method for controlling water supply to a mixing station provided in an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a method for controlling water supply to a mixing station. The mixing station includes a water supply system. The water supply system includes a water pump, a water supply pipe, a water storage device, a flow detection device and a water quantity detection device. The flow detection device is used to detect the water flow in the water supply pipe, and the water quantity detection device is used to detect the water quantity in the water storage device. The method is described by taking the application of the method to a processor as an example. The method may include the following steps.

[0031] Step S101, obtaining the actual required water volume of the mixing station.

[0032] Step S102, determining the target water supply according to the actual water demand.

[0033] Step S103, controlling the water pump to start.

[0034] Step S104, obtaining the accumulated flow detected by the flow detection device.

[0035] Step S105, converting the accumulated flow into accumulated water supply.

[0036] Step S106: When the accumulated water supply reaches the target water supply, the water pump is controlled to stop working.

[0037] Step S107, obtaining the measured water volume detected by the water volume detection device.

[0038] Step S108: When the actual required water volume is equal to the measured water volume, it is determined that the water supply is completed.

[0039] In the embodiment of the present application, the flow detection device can be a flow meter, such as an orifice flow meter, a rotor flow meter, a velocity tube and a differential pressure flow meter, etc. The flow detection device is arranged on the pipeline of the water supply pipe, near one end of the water storage device. The water quantity detection device can be a level meter (including a radar water level meter, a float level meter, a pressure level meter or an ultrasonic level meter, etc.), a water quantity sensor and a weight sensor, etc., and the installation position is different according to the different equipment used. It can be understood that the water quantity in the embodiment of the present application can refer to the weight or volume of water, etc. In one example, the water quantity detection device can be a weight sensor, which is arranged at the bottom of the water storage device and is used to detect the weight of the water in the water storage device. In another example, the water quantity detection device can be a level meter or a water quantity sensor, which determines the amount of water in the water storage tank by measuring the change of the water level in the water storage device and combining the basic parameters of the water storage device. In the embodiment of the present application, during the operation of the water supply system, the water pump extracts the amount of water required for the mixing operation into the water supply pipe, and flows into the water storage device through the water supply pipe for temporary storage for use during the mixing operation.

[0040] Specifically, taking the water supply of a certain round of operation in a mixing station as an example, the processor can first obtain the actual water demand of the mixing station for this round of mixing operation. The actual water demand can be directly input by the operator through the display device after conversion. Then the target water supply is determined according to the actual water demand. The target water supply refers to the amount of water that needs to flow through the flow detection device. In one example, the target water supply can be equal to the actual water demand. In another example, considering the impact of pipeline transmission, there may be a situation where some water remains in the pipeline. At this time, the target water supply needs to be determined based on the residual water situation in the pipeline and the actual water demand.

[0041] Furthermore, after the target water supply is determined, the processor sends an instruction to control the water pump to start and start continuous water supply. After the water pump is started, the water flow in the water supply pipe, that is, the accumulated water volume, is monitored and recorded in real time through the flow detection device. At the same time, the processor determines the accumulated water supply in real time based on the accumulated water volume obtained in real time, combined with the pipe diameter and water flow velocity of the water supply pipe and other parameters. At the same time, the accumulated water supply and the target water supply are compared in real time. When it is detected that the accumulated water supply reaches the target water supply, the processor sends an instruction to control the water pump to stop working to prevent excessive water supply and affect the proportion of subsequent mixing station operations.

[0042] It can be understood that after the water pump stops working and the water in the water supply pipe falls into the water storage device, that is, the measured value of the water volume detection device no longer changes, in order to further ensure accurate water supply, the water volume in the water storage device can be detected by the water volume detection device, that is, the water volume is measured. Then, the measured water volume is compared with the actual required water volume for further verification. When the actual required water volume is equal to the measured water volume, it means that the effect of accurate water supply has been achieved, and it is determined that this round of water supply is completed.

[0043] In this way, the embodiment of the present application eliminates the components such as the precision scale box and precision metering valve in the traditional water supply system, simplifies the liquid pipeline structure, reduces space occupancy, and is conducive to the compact layout of the mixing station. And only by collecting the signal feedback of the flow detection device and the water volume detection device, it is only necessary to control the water pump, avoiding the control of multiple control points in sequence and optimizing the control program. And by accurately controlling the start and stop of the water pump, and real-time monitoring and calculation of the water supply, the stability and accuracy of the water supply system of the mixing station are ensured. The cross-section of the liquid pipeline profile does not change in diameter, and the supply efficiency is better than that of the traditional water supply system, which shortens the loading time and is conducive to improving the overall production efficiency.

[0044] The above technical scheme proposes a water supply system, which includes a water pump, a water supply pipe, a water storage device, a flow detection device and a water volume detection device. The flow detection device is used to detect the water flow in the water supply pipe, and the water volume detection device is used to detect the water volume in the water storage device. Furthermore, by obtaining the actual required water volume of the mixing station and determining the target water supply volume according to the actual required water volume, the water pump is controlled to start, and then the cumulative flow detected by the flow detection device is obtained in real time, and the cumulative flow is converted into the cumulative water supply volume. When the cumulative water supply volume reaches the target water supply volume, the water pump is controlled to stop working, and then the measured water volume detected by the water volume detection device is obtained. When the actual required water volume is equal to the measured water volume, it is determined that the water supply is completed. The present application simplifies the composition of liquid pipeline components, reduces the installation space, is conducive to the compact layout of the mixing station, and by collecting the signal feedback of the flow detection device and the water volume detection device, only the water pump needs to be controlled, avoiding the control of multiple control points in sequence and optimizing the control program.

[0045] In an embodiment of the present application, obtaining the actual required water volume of the mixing station may include: obtaining the mix ratio and production volume of the mixing operation; and determining the actual required water volume of the mixing station based on the mix ratio and production volume.

[0046] It can be understood that the mix ratio refers to the ratio between the various components of concrete (such as cement, water, sand, gravel, etc.). The production volume refers to the amount of concrete that the mixing station needs to produce in this operation, usually in cubic meters (m 3 ) as a unit. Specifically, the processor can obtain the mix ratio and production volume of this mixing operation, and then determine the amount of water required per cubic meter of concrete (i.e., water-cement ratio) based on the mix ratio. Then, the amount of water required per cubic meter of concrete is multiplied by the production volume to obtain the actual water demand of the mixing station.

[0047] In an embodiment of the present application, determining the target water supply according to the actual required water volume may include: obtaining the remaining water volume in the water storage device through a water volume detection device; and determining the target water supply according to the actual required water volume and the remaining water volume.

[0048] It is understandable that before water supply, there may be residual water in the water storage device. For example, if the water in the water storage device was not used up in the last round of water supply, there will be residual water. In order to save water resources and ensure the accuracy of this round of water supply, the residual water in the water storage device can be detected by a water quantity detection device, and then the target water supply of this round can be determined based on the actual required water quantity and the residual water quantity. In one example, the target water supply can be the difference between the actual required water quantity and the residual water quantity. In this way, the accuracy of water supply can be ensured while saving water resources.

[0049] In an embodiment of the present application, determining the target water supply based on the actual water demand and the remaining water volume may include: obtaining the historical average error value and the historical average loss; determining the target water supply based on the actual water demand, the remaining water volume, the historical average error value and the historical average loss.

[0050] It can be understood that the historical average error refers to the average value of the water supply error in the historical water supply process. The water supply error of each round of water supply is the difference between the measured water volume and the actual required water volume in each round of water supply. The historical average loss is the average value of the water supply loss in the historical water supply process. The water supply loss of each round of water supply can be determined based on the cumulative water supply, measured water volume and remaining water volume of each round. If it is the first round of water supply, the historical average error value and the historical average loss are both zero.

[0051] In order to improve the accuracy of water supply, the target water supply volume of this round of water supply can be determined in combination with the actual demand water volume, the remaining water volume, the historical average error value and the historical average loss volume. It should be noted that the specific calculation method of the target water supply volume can be adaptively adjusted according to the calculation method of the historical average error value and the historical average loss volume. In this way, the accuracy of water supply can be further improved.

[0052] In an embodiment of the present application, the method may further include: when the actual required water volume is not equal to the measured water volume, determining that the difference between the measured water volume and the actual required water volume is a water supply error; judging whether the water supply error is within a preset error range; when the water supply error is within the preset error range, determining that the water supply is completed, and correcting the historical average error value according to the water supply error.

[0053] It can be understood that when the actual demand water volume is not equal to the measured water volume, it means that there is a certain error in this round of water supply. At this time, the processor can determine the water supply error according to the difference between the measured water volume and the actual demand water volume. Considering that there may be a certain error range in the actual operation scene, it can be judged whether the water supply error is within the preset error range. Among them, the preset error range refers to the error tolerance range corresponding to the actual operation standard, which is a set value. In one example, when the water supply error is within the preset error range, it means that the error of this round of water supply is within the error tolerance range, which can be directly used for the next link to determine that the execution of this round of water supply task is completed. Preferably, in order to improve the accuracy of subsequent water supply, the processor can correct the historical average error value according to the water supply error, that is, combine the historical average error value and the water supply error of this round to re-determine the historical average error value, and update the historical average error value set in the system. In this way, through the collection, analysis and summary of big data, the system can continuously learn, improve and upgrade to achieve high-precision control requirements.

[0054] In another example, when the water supply error is not within the preset error range, it means that the error of this round of water supply exceeds the error tolerance range and the water supply needs to be further adjusted. Therefore, the processor can compare the measured water volume and the actual required water volume. When the measured water volume is less than the actual required water volume, the water pump is controlled to turn on until the measured water volume reaches the actual required water volume. When the measured water volume is greater than the actual required water volume, a prompt message is output to prompt the operator of the water supply error so that the operator can carry out targeted processing. It can be understood that in the actual operation process, oversupply usually does not occur. In this way, the water supply requirements are met by further adjusting the water supply.

[0055] In an embodiment of the present application, when the water supply error is within a preset error range, the method may further include: determining the water supply loss amount based on the cumulative water supply, the measured water volume and the remaining water volume; and correcting the historical average loss amount based on the water supply loss amount.

[0056] It can be understood that in order to improve the accuracy of subsequent water supply, when the water supply error is within the preset error range, the processor can correct the historical average loss according to the water supply error. Specifically, the water supply loss is first determined based on the cumulative water supply, the measured water volume and the remaining water volume, and then the historical average loss is re-determined based on the historical average loss and the water supply loss of this round, and the historical average loss set in the system is updated. In one example, the difference between the measured water volume and the remaining water volume can be determined first to obtain the measured water supply, and then the water supply loss of this round can be determined based on the difference between the cumulative water supply and the measured water supply. In this way, through the collection, analysis and summary of big data, the system can continuously learn, improve and upgrade to achieve high-precision control requirements.

[0059] Specifically, the water supply system in the embodiment of the present application includes a processor, a water pump, a water supply pipe, a water storage device, a flow detection device and a water volume detection device. Among them, the water supply pipe includes a water inlet pipe and a water outlet pipe, one end of the water inlet pipe is connected to the water pump, and one end of the water outlet pipe is connected to the water storage device. The water storage device can be a container for storing water such as a water tank, and its size is determined by the working scale of the mixing station. During the operation of the water supply system, the water pumped by the water pump flows into the water supply pipe and flows out of the water outlet pipe to the water storage device.

[0060] In the embodiments of the present application, the flow detection device may be a flow meter, such as an orifice flow meter, a rotor flow meter, a velocity tube and a differential pressure flow meter, etc. The flow detection device is arranged on the pipeline of the water supply pipe, near one end of the water storage device.

In another example, the water quantity detection device may be a level meter or a water quantity sensor, which determines the amount of water in the water storage tank by measuring the change of the water level in the water storage device and combining the basic parameters of the water storage device.

[0061] In the embodiment of the present application, the water pump, the flow detection device and the water volume detection device communicate with the processor respectively, and the processor can receive the detection data sent by the flow detection device and the water volume detection device, and control the opening and closing of the water pump by sending instructions according to the control logic in the above-mentioned embodiment. During the operation of the water supply system, the water pump extracts the amount of water required for the mixing operation into the water supply pipe, and flows into the water storage device through the water supply pipe for temporary storage for use during the mixing operation.
