Description

Technical Field

[0001] This application relates to the field of deep well casting equipment technology, and in particular to a method, device, system, equipment and storage medium for controlling cooling water pumps in deep well casting. Background Technology

[0002] Research has revealed that the traditional control method for cooling water pumps in deep well casting involves directly controlling the pump motor to start via a soft starter using a start button, and immediately stopping the pump when the stop button is pressed. During production, accidental operation can lead to pump shutdowns, resulting in a lack of cooling water in deep well casting. Currently, the control method for cooling water pumps in deep well casting machines suffers from simplistic logic and a lack of status recognition capabilities, making it difficult to effectively prevent unplanned shutdowns caused by human error or signal interference, thus posing a serious safety hazard of cooling water loss in deep well casting production. Summary of the Invention

[0003] This invention provides a method, apparatus, system, equipment, and storage medium for controlling cooling water pumps in deep well casting, to at least solve the problem of serious safety hazards caused by cooling water loss during deep well casting production due to unplanned shutdowns caused by human error. The technical solution of this invention is as follows: According to a first aspect of the present invention, a method for controlling a cooling water pump in a deep well casting machine is provided. The method includes: real-time acquisition of operating data of the cooling water pump and the operating status of the deep well casting machine; when a shutdown signal of the cooling water pump is detected, determining whether the operating data meets the operation stop condition, and determining whether the operating status meets the status stop condition; and generating a shutdown command for controlling the cooling water pump to stop when it is determined that the operating data meets the operation stop condition and the operating status meets the status stop condition.

[0004] As one implementation method, if it is determined that the operating data does not meet the conditions for stopping operation, or if it is determined that the operating status does not meet the conditions for stopping the status, the cooling water pump is controlled to continue injecting water.

[0005] As one implementation method, the operating data includes the water pump outlet pressure and the water pump motor current; the operating status includes the stopped casting status and the normal casting status; the method also includes: determining that the water pump outlet pressure is greater than a preset pressure threshold and the water pump motor current is less than a preset current threshold, determining that the operating data meets the operation stop conditions; and determining that the operating status of the casting machine is the stopped casting status, determining that the operating status meets the status stop conditions.

[0006] As one implementation method, it is determined that the pump outlet pressure is less than or equal to a preset pressure threshold, or the pump motor current is greater than or equal to a preset current threshold, and the operating data does not meet the operation stop conditions; and it is determined that the casting machine is in normal casting state, and the operating state does not meet the state stop conditions.

[0007] In this implementation, a dual interlocking judgment logic is constructed to ensure that shutdown is only permitted when the water pump is under light load or no load and the casting machine has stopped running. If casting is still in normal operation or the water pump is still running under load, shutdown and continued water injection are refused, effectively preventing the cooling water from being cut off due to false signals or misoperation during the casting process.

[0008] As one implementation method, the outlet flow rate of the cooling water pump is monitored in real time; when the outlet flow rate is detected to be lower than the preset flow rate threshold, an emergency protection command is automatically triggered; the emergency protection command includes starting the emergency cooling water source and controlling the casting machine to decelerate until it stops running.

[0009] In this embodiment, real-time monitoring of the cooling water pump outlet flow rate is added, and an emergency protection command independent of the shutdown signal is set. In this way, through a tiered response, the emergency water source is activated first to maintain cooling, while casting is stopped in an orderly manner to avoid molten metal accidents caused by sudden water cut-off.

[0010] As one implementation, when a shutdown signal of the cooling water pump is detected, after determining whether the operating data meets the operation stop conditions and whether the operating status meets the status stop conditions, the method further includes: visually displaying the operating data and the operating status; and after a second confirmation of the generated shutdown command, determining to execute the shutdown command.

[0011] In this implementation, the visualization of operating data and status allows operators to intuitively see the current pump pressure, current, casting status, and upcoming control commands. Furthermore, a secondary confirmation is added to the automated judgment to prevent misjudgments by the intelligent judgment logic due to abnormal monitoring data, significantly improving production safety and equipment reliability in the casting process.

[0012] According to a second aspect of the present invention, a control device for a cooling water pump in a deep well casting machine is provided. The device includes: a data acquisition unit configured to acquire, in real time, operating data of the cooling water pump and the operating status of the deep well casting machine; a judgment unit configured to, when a shutdown signal of the cooling water pump is detected, determine whether the operating data meets a shutdown condition and whether the operating status meets a shutdown condition; and a determination unit configured to, if it is determined that the operating data meets the shutdown condition and the operating status meets the shutdown condition, generate a shutdown command for controlling the cooling water pump to stop.

[0013] According to a third aspect of the present invention, a deep well casting cooling water pump control system is provided. The system includes a data acquisition module, a judgment module, and a determination module. The data acquisition module further includes a pressure sensor and a signal conversion unit. The data acquisition module, the judgment module, and the determination module are communicatively connected.

[0014] The data acquisition module is configured to acquire the operating data of the cooling water pump and the operating status of the deep well casting machine in real time; the pressure sensor is installed at the outlet of the cooling water pump to monitor the pump outlet pressure in real time; the signal conversion unit is configured to convert the analog quantity of the cooling water pump's operating data into a visualized engineering quantity.

[0015] The judgment module is configured to determine whether the operating data meets the operation stop conditions and whether the operating status meets the status stop conditions when a shutdown signal of the cooling water pump is detected.

[0016] The determination module is configured to generate a shutdown command to control the cooling water pump to stop when it is determined that the running data meets the running stop condition and the running status meets the status stop condition.

[0017] The system is configured to perform a deep well casting cooling water pump control method as described in the first aspect and any of its possible implementations.

[0018] According to a fourth aspect of the present invention, a deep well casting cooling water pump control device is provided, the device being configured to perform a deep well casting cooling water pump control method as described in the first aspect and any possible implementation thereof.

[0019] According to a fifth aspect of the present invention, a computer-readable storage medium is provided, on which instructions are stored, such that when the instructions in the computer-readable storage medium are executed by a processor of a deep well casting cooling water pump control device, the deep well casting cooling water pump control device is able to perform a deep well casting cooling water pump control method as described in the first aspect and any possible implementation thereof.

[0020] According to a sixth aspect of the present invention, a computer program product is provided, the computer program product including computer instructions, which, when the computer instructions are executed on a deep well casting cooling water pump control device, cause the deep well casting cooling water pump control device to perform the deep well casting cooling water pump control method of the first aspect and any possible implementation thereof.

[0021] The technical solution provided by the embodiments of the present invention brings at least the following beneficial effects: After receiving a shutdown signal, the present invention constructs an interlocking judgment logic based on the real-time operating data of the cooling water pump and the operating status of the foundry machine, respectively verifying whether the operating data meets the shutdown data conditions and whether the operating status meets the shutdown status conditions. Only when both of the above-mentioned shutdown conditions are met simultaneously is it determined that the cooling water injection can be stopped, thereby effectively identifying that the shutdown signal is not an invalid signal triggered by misoperation, but a valid shutdown signal. Then, based on the valid shutdown signal, a shutdown control command for controlling the shutdown of the cooling water pump is generated. Through the above-mentioned interlocking judgment logic control method, based on the intelligently identified casting conditions and cooling water pump conditions, invalid shutdown signals triggered by misoperation can be effectively screened, ensuring the validity and accuracy of the shutdown signal on which the shutdown control command is based, thereby reducing the probability of abnormal shutdown of the cooling water pump due to invalid shutdown signals, and significantly improving the production safety and equipment operation reliability of the casting process.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] Before providing a detailed description of the deep well casting cooling water pump control method provided in this application embodiment, let's briefly introduce the application scenarios and implementation environment involved in this application embodiment.

[0028] The traditional control method for cooling water pumps in deep well casting involves directly controlling the pump motor to start operation via a soft starter using a start button. Pressing the stop button immediately stops the pump. During production, accidental operation can lead to pump shutdowns, resulting in a lack of cooling water in the deep well casting process. Currently, the control method for cooling water pumps in deep well casting machines suffers from simplistic logic and a lack of status recognition capabilities. This makes it difficult to effectively prevent unplanned shutdowns caused by human error or signal interference, posing a serious safety hazard of cooling water loss in deep well casting production.

[0029] To address the aforementioned issues, this application proposes a control method for cooling water pumps in deep well casting. Upon receiving a shutdown signal, the method constructs an interlocking judgment logic based on real-time operating data of the cooling water pump and the operating status of the casting machine. This intelligently identifies the casting conditions and cooling water pump conditions, effectively identifying invalid shutdown signals triggered by misoperation. This ensures the validity and accuracy of the shutdown signals upon which the shutdown control commands are based, thereby reducing the probability of erroneous shutdowns of the cooling water pump due to invalid shutdown signals and significantly improving production safety and equipment reliability in the casting process.

[0030] Secondly, the implementation architecture involved in this application will be briefly introduced below.

[0031] Figure 1 This is a schematic diagram of a deep well casting cooling water pump control system provided in this application. Figure 1 .like Figure 1 As shown, the deep well casting cooling water pump control system includes a data acquisition module 11, a judgment module 12, and a determination module 13. The data acquisition module 11, judgment module 12, and determination module 13 are connected via communication.

[0032] The data acquisition module 11 is configured to collect real-time operating data of the cooling water pump and the operating status of the deep well casting machine.

[0033] The judgment module 12 is configured to determine whether the operating data meets the operation stop conditions and whether the operating status meets the status stop conditions when a shutdown signal of the cooling water pump is detected.

[0034] The determination module 13 is configured to generate a shutdown command for controlling the cooling water pump to stop when it is determined that the running data meets the running stop condition and the running status meets the status stop condition.

[0035] Among them, such as Figure 2 As shown, the data acquisition module 11 includes a pressure sensor 111 and a signal conversion unit 112.

[0036] Pressure sensor 111 is installed at the outlet of the cooling water pump and is configured to monitor the pump outlet pressure in real time.

[0037] The signal conversion unit 112 is configured to convert analog quantities of operating data of the cooling water pump into visualized engineering quantities.

[0038] In one implementation, the deep well casting cooling water pump control system is a PLC programmable logic control system.

[0039] The pressure sensor 111 has a measurement range of 0 MPa to 1.0 MPa and an analog output range of 4 mA to 20 mA.

[0040] The signal conversion unit 112 includes an analog input unit and a digital input unit. The analog quantity of the collected water pump outlet pressure and the analog quantity of the cooling water pump motor current are input to the signal conversion unit 112 through the analog input unit. In addition, the digital quantity of the status bit of the casting machine's operating status is input to the signal conversion unit 112 through the digital input unit.

[0041] For ease of understanding, the following detailed description of the deep well casting cooling water pump control method provided in this application is provided in conjunction with the accompanying drawings.

[0042] Figure 3 This is a flowchart illustrating a deep well casting cooling water pump control method according to an exemplary embodiment, such as... Figure 3 As shown, the deep well casting cooling water pump control method includes the following steps.

[0043] S21 collects real-time operating data of cooling water pumps and operating status of deep well casting machines.

[0044] The operating data includes the water pump outlet pressure and the water pump motor current.

[0045] The operating status includes the stopped casting status and the normal casting status.

[0046] There is a one-to-one correspondence between the cooling water pump and the casting machine; the casting machine's stop signal can only control the corresponding cooling water pump.

[0047] By integrating and judging multi-dimensional parameters, the system's ability to perceive operating conditions is effectively improved, enabling more accurate and reliable control decisions.

[0048] S22, when a shutdown signal of the cooling water pump is detected, determine whether the operating data meets the operation stop conditions, and determine whether the operating status meets the status stop conditions.

[0049] The operation stops when the pump outlet pressure is greater than the preset pressure threshold and the pump motor current is less than the preset current threshold.

[0050] The condition for stopping the state is that the casting machine is in a stopped casting state.

[0051] The status bit is 1 when the casting machine is in a stopped casting state; and 0 when it is in a normal casting state.

[0052] S23, if it is determined that the operating data meets the operation stop conditions and the operating status meets the status stop conditions, generate a stop command to control the cooling water pump to stop.

[0053] In one embodiment, it is determined that the water pump outlet pressure is greater than a preset pressure threshold and the water pump motor current is less than a preset current threshold, thus determining that the operating data meets the operation stop condition; and it is determined that the operating state of the casting machine is a stopped casting state, thus determining that the operating state meets the state stop condition.

[0054] Understandably, when the casting machine stops pouring, the cooling water valve automatically closes. At this time, the operating current value of the cooling water pump motor is detected to be less than the preset current threshold and the pump outlet pressure value is greater than the preset voltage threshold. The status bit of the casting machine ending casting jumps to 1, indicating that the casting machine is in a stopped casting state. Only then can the water pump be stopped, thereby generating a stop command to control the cooling water pump to stop.

[0055] In another implementation, if it is determined that the operating data does not meet the operation stop conditions, or that the operating status does not meet the status stop conditions, the cooling water pump continues to inject water.

[0056] Specifically, if the pump outlet pressure is less than or equal to a preset pressure threshold, or the pump motor current is greater than or equal to a preset current threshold, the operating data does not meet the operation stop conditions; and if the casting machine is in normal casting state, the operating state does not meet the state stop conditions.

[0057] Understandably, when the casting machine is in normal casting mode, the current value of the water pump motor is greater than the set value, the pressure value of the water pump outlet is less than the set value, and the status of ending casting is 0. Under these circumstances, it is not allowed to stop the water pump.

[0058] Thus, if any condition is not met, the shutdown signal is considered invalid. This ensures that the water pump will not stop due to misoperation during deep well casting production, thereby guaranteeing safe production.

[0059] As can be seen from the two implementation methods described above, by constructing a dual interlocking judgment logic for operation stop conditions and state stop conditions, it is ensured that the machine is only allowed to stop when the water pump is in a light load or no-load state and the casting machine has stopped running. If the casting is still in normal operation, or the water pump is still running under load, the machine is refused to stop and continue water injection, effectively preventing the cooling water from being cut off due to false signals or misoperation during the casting process.

[0060] Optionally, the outlet flow rate of the cooling water pump can be monitored in real time; when the outlet flow rate is detected to be lower than the preset flow rate threshold, an emergency protection command is automatically triggered; the emergency protection command includes starting the emergency cooling water source and controlling the casting machine to decelerate until it stops running.

[0061] In this way, by monitoring the cooling water flow rate in real time during production, the foundry machine automatically enters emergency mode when the flow rate suddenly decreases or disappears. Emergency water is automatically introduced, and the foundry machine is slowed down until it stops, ensuring the safety of deep well casting production. This step, by adding real-time monitoring of the cooling water pump outlet flow rate and setting emergency protection commands independent of the shutdown signal, allows for a tiered response. Emergency water is first activated to maintain cooling, while casting is stopped in an orderly manner, preventing molten metal accidents caused by sudden water outages.

[0062] Optionally, when a shutdown signal of the cooling water pump is detected, after determining whether the operating data meets the operation stop conditions and whether the operating status meets the status stop conditions, the operating data and operating status are visualized; and after a second confirmation of the generated shutdown command, the shutdown command is executed.

[0063] In one implementation, when the stop button of the cooling water pump is pressed, after intelligent interlock judgment logic identification, a pop-up prompt will appear on the human-machine interaction touch screen, displaying the current operating data of the water pump and the operating status of the casting machine. The water pump can only be stopped when the conditions for stopping the water pump are met after secondary confirmation.

[0064] In this implementation, the visualization of operating data and status allows operators to intuitively see the current pump pressure, current, casting status, and upcoming control commands. Furthermore, a secondary confirmation is added to the automated judgment to prevent misjudgments by the intelligent judgment logic due to abnormal monitoring data, significantly improving production safety and equipment reliability in the casting process.

[0065] In summary, after detecting a stop signal, a stop control command to stop the cooling water pump is only generated after receiving a stop signal from the casting machine, and when the water pump outlet pressure and water pump motor current values ​​meet the conditions, and after secondary confirmation on the touch screen. This ensures that the cooling water pump does not stop running in any state other than stopping casting, thus guaranteeing a smooth and safe casting process.

[0066] In one specific implementation, the control process of the deep well casting cooling water pump is as follows.

[0067] Firstly, it collects operational data in real time and converts analog signals into readable engineering quantities.

[0068] Convert the analog signal of the water pump outlet pressure into an engineering quantity value, specifically as follows: Figure 4 As shown.

[0069] Wherein, #"AI-input" is the analog input value of the pump outlet pressure; 27648 is the upper limit of the analog input, 0 is the lower limit of the analog input and the lower limit of the engineering quantity; #Median is the intermediate variable; #"Rating Value" is the upper limit of the engineering quantity, and #"Water Pressure" is the actual value of the pump outlet pressure.

[0070] The analog signal of the water pump motor current is converted into an engineering value through a program, specifically as follows: Figure 5 As shown.

[0071] Wherein, #"AI-input" is the analog input value of the water pump motor current; 27648 is the upper limit of the analog input; 0 is the lower limit of the analog input and the lower limit of the engineering quantity; #Median is the intermediate variable; #"Rating Value" is the upper limit of the engineering quantity; and #"Current Value" is the actual value of the water pump motor current.

[0072] Secondly, an interlocking judgment logic is constructed. In remote control mode, the water pump can only stop operating when the actual water pump motor current is less than or equal to a preset current threshold, the water pump outlet pressure is greater than or equal to a preset voltage threshold, the casting machine is in the finished casting state, and the status bit is 1. Specifically, as follows... Figure 6 As shown.

[0073] Among them, #"Remote / short-sangge" is the local / remote mode; #"Re-stop" is to remotely stop the water pump; #"Set-Current" is the preset current threshold; #"Set-Pressure" is the preset voltage threshold; #Static_7 is the casting machine operating status; and #Static_5 is the intermediate variable for stopping the water pump.

[0074] Third, after determining that all stopping conditions are met, output to stop the water pump operation, specifically as follows: Figure 7 As shown.

[0075] Fourth, after acquiring the operating data and status, and through the interlocking judgment logic, a shutdown control command for the cooling water pump is generated. This command calls the subroutine for starting and stopping the deep well casting cooling water pump, controlling the pump to stop. Specifically, as follows... Figure 8 As shown.

[0076] To achieve the above functions, the deep well casting cooling water pump control device includes corresponding hardware structures and / or software modules for performing each function.

Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0083] As one implementation method, the judgment unit 302 is specifically configured to: determine if the water pump outlet pressure is less than or equal to a preset pressure threshold, or if the water pump motor current is greater than or equal to a preset current threshold, and determine if the operating data does not meet the operation stop condition; and determine if the casting machine's operating state is a normal casting state, and determine if the operating state does not meet the state stop condition.

[0084] As one implementation method, the specific configuration of the unit 303 is as follows: it monitors the outlet flow rate of the cooling water pump in real time; when the outlet flow rate is detected to be lower than the preset flow rate threshold, it automatically triggers an emergency protection command; the emergency protection command includes starting the emergency cooling water source and controlling the casting machine to decelerate until it stops running.
