Description

Technical Field

[0001] This invention belongs to the technical field of metallurgical hydraulic systems, specifically relating to a hydraulic energy-saving method, system, terminal, and storage medium for a rolling mill. Background Technology

[0002] The hydraulic system provides power to actuators and other systems. During operation, the flow rate varies significantly due to changes in production conditions. In standby mode, some field equipment has zero mechanical load, but the motors driving the hydraulic pumps are in full-run pressure-maintaining mode, resulting in substantial wasted power consumption. Manually switching these motors on and off is not only complex, but untimely activation can easily cause production delays. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a hydraulic energy-saving method, system, terminal and storage medium for rolling mills to solve the above-mentioned technical problems.

[0004] In a first aspect, the present invention provides a hydraulic energy-saving method for a rolling mill, comprising:

[0005] Monitor production data and issue management tasks based on the production data, which includes the inventory of production materials and the operating status of the production line;

[0006] Based on the aforementioned production status, the theoretical number of hydraulic pumps required for production in the short term is estimated.

[0007] The actual number of hydraulic pumps operating on the production line is collected, and the actual number of hydraulic pumps operating on the production line is adjusted to the theoretical number of hydraulic pumps by starting or stopping some of the hydraulic pump drive motors.

[0008] Furthermore, monitor production data and issue management tasks based on the production data, which includes production material inventory and production line operating status, including:

[0009] The raw material inventory is collected periodically. If the actual inventory is lower than the set raw material threshold, the raw material replenishment waiting time is obtained. The theoretical power of the production line is generated based on the actual inventory and the raw material replenishment waiting time.

[0010] When the billet waiting time and tapping time are obtained from the MES system, the docking heating furnace combustion system generates a corresponding management task, which is limited to minimizing the production line power during the waiting time.

[0011] Monitor the on-site data of key equipment on the production line, including voltage and current data. If abnormal on-site data of key equipment is detected, a management task is generated to reduce the power of the production line to a minimum.

[0012] Furthermore, raw material inventory is collected periodically. If the actual inventory is lower than a set raw material threshold, the raw material replenishment waiting time is obtained. Based on the actual inventory and the raw material replenishment waiting time, the theoretical power of the production line is generated, including:

[0013] A raw material monitoring thread is created, which uses a timer to determine whether the raw material inventory has been received from the manually maintained terminal within a set period.

[0014] If not, an alarm message will be generated.

[0015] Furthermore, the actual number of hydraulic pumps operating on the production line is collected, and the actual number of hydraulic pumps operating on the production line is adjusted to the theoretical number of hydraulic pumps by starting or stopping some of the hydraulic pump drive motors, including:

[0016] Maintain the hydraulic pump status list, which synchronously records the basic information of the hydraulic pumps currently in operation;

[0017] Retrieve the number of hydraulic pumps currently in operation from the list and compare the actual number of hydraulic pumps in operation with the theoretical number of hydraulic pumps.

[0018] If the actual number of hydraulic pumps in operation is greater than the theoretical number of hydraulic pumps, then some hydraulic pump drive motors will be shut down. The number of hydraulic pump drive motors shut down is equal to the difference between the actual number of hydraulic pumps in operation and the theoretical number of hydraulic pumps.

[0019] If the actual number of hydraulic pumps in operation is less than the theoretical number of hydraulic pumps, then some hydraulic pump drive motors will be started sequentially according to the preset start-up sequence. The number of hydraulic pump drive motors started is equal to the difference between the theoretical number of hydraulic pumps and the actual number of hydraulic pumps in operation.

[0020] In a second aspect, the present invention provides an energy-saving system for a rolling mill, comprising:

[0021] The data monitoring unit is used to monitor production data and issue management tasks based on the production data, which includes the inventory of production materials and the operating status of the production line.

[0022] The target calculation unit is used to estimate the theoretical number of hydraulic pumps required for production in the short term based on the management task.

[0023] The energy-saving execution unit is used to collect the actual number of hydraulic pumps operating on the production line, and adjust the actual number of hydraulic pumps operating on the production line to the theoretical number of hydraulic pumps by starting or stopping some hydraulic pump drive motors.

[0024] Furthermore, the data monitoring unit includes:

[0025] The first monitoring module is used to periodically collect the raw material inventory. If the actual inventory is lower than the set raw material threshold, the raw material replenishment waiting time is obtained, and the theoretical power of the production line is generated based on the actual inventory and the raw material replenishment waiting time.

[0026] The second monitoring module is used to connect to the heating furnace combustion system. When the billet waiting time and the tapping time are obtained from the MES system, a corresponding management task is generated. The management task is limited to reducing the production line power to the minimum during the gas supply shutdown period.

[0027] The third monitoring module is used to monitor the on-site data of key equipment on the production line. The on-site data includes voltage and current data. If abnormal on-site data of key equipment is detected, a management task is generated to reduce the power of the production line to the minimum.

[0028] Furthermore, the first monitoring module includes:

[0029] The deadline monitoring submodule is used to create a raw material monitoring thread. The monitoring thread determines whether the raw material inventory has been received from the manual maintenance terminal within a set deadline based on a timer.

[0030] The alarm generation submodule is used to generate an alarm prompt if the raw material inventory is not uploaded by the manual maintenance terminal within a set period.

[0031] Furthermore, the energy-saving execution unit includes:

[0032] The list maintenance module is used to maintain the hydraulic pump status list, which synchronously records the basic information of the hydraulic pumps that are currently running;

[0033] The quantity comparison module is used to retrieve the number of hydraulic pumps currently in operation from the list and compare the actual number of hydraulic pumps in operation with the theoretical number of hydraulic pumps.

[0034] The first execution module is used to shut down some hydraulic pump drive motors if the actual number of operating hydraulic pumps is greater than the theoretical number of hydraulic pumps. The number of hydraulic pump drive motors shut down is equal to the difference between the actual number of operating hydraulic pumps and the theoretical number of hydraulic pumps.

[0035] The second execution module is used to start some hydraulic pump drive motors in a preset starting sequence if the actual number of operating hydraulic pumps is less than the theoretical number of hydraulic pumps. The number of hydraulic pump drive motors started is equal to the difference between the theoretical number of hydraulic pumps and the actual number of operating hydraulic pumps.

[0036] Thirdly, an operating terminal is provided, comprising:

[0037] Processor, memory, among which,

[0038] This memory is used to store computer programs.

[0039] The processor is used to retrieve and run the computer program from memory, causing the terminal to perform the terminal method described above.

[0040] Fourthly, a computer storage medium is provided, wherein instructions are stored therein, which, when executed on a computer, cause the computer to perform the methods described in the above aspects.

[0041] The beneficial effects of the present invention are that the hydraulic energy-saving method, system, terminal and storage medium for rolling mills provided by the present invention can predict the flow demand of hydraulic stations in standby state by monitoring the production status of the production line, thereby generating management tasks, and controlling the number of hydraulic pumps running on the production line based on the management tasks, thereby avoiding the waste of energy caused by the full operation of hydraulic pumps.

[0042] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects. Attached Figure Description

[0043] 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, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0044] Figure 1 This is a schematic flowchart of a method according to an embodiment of the present invention.

[0045] Figure 2 This is a schematic block diagram of a system according to an embodiment of the present invention.

[0046] Figure 3 This is a schematic diagram of the structure of a terminal provided in an embodiment of the present invention. Detailed Implementation

[0047] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0048] Figure 1 This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The implementing entity can be a hydraulic energy-saving system for a rolling mill.

[0049] like Figure 1 As shown, the method includes:

[0050] Step 110: Monitor production data and issue management tasks based on the production data, which includes the inventory of production materials and the operating status of the production line;

[0051] Step 120: Estimate the theoretical number of hydraulic pumps required for production in the short term based on the management task;

[0052] Step 130: Collect the actual number of hydraulic pumps operating on the production line, and adjust the actual number of hydraulic pumps operating on the production line to the theoretical number of hydraulic pumps by starting or stopping some hydraulic pump drive motors.

[0053] By utilizing the working characteristics of the constant pressure variable displacement piston pump commonly used in hydraulic systems, the "one-key energy saving" mode is activated in the "standby state" to reduce the pump operation of the hydraulic station while the equipment remains in its initial state; in the "working state" to activate the "normal" mode, the hydraulic pumps are started in sequence according to the set number, thereby achieving energy saving in the hydraulic system.

[0054] To facilitate understanding of the present invention, the following description further illustrates the hydraulic energy-saving method for rolling mills provided by the present invention, based on the principle of the present invention and in conjunction with the process of energy-saving management of the hydraulic station of the rolling mill in the embodiments.

[0055] Specifically, the hydraulic energy-saving method for the rolling mill includes:

[0056] S1. Monitor production data and issue management tasks based on the production data, which includes the inventory of production materials and the operating status of the production line.

[0057] (1) Periodically collect raw material inventory. If the actual inventory is lower than the set raw material threshold, obtain the raw material replenishment waiting time and generate the theoretical power of the production line based on the actual inventory and the raw material replenishment waiting time.

[0058] A raw material monitoring thread is created. The monitoring thread determines whether the raw material inventory is received from the manual maintenance terminal within a set period based on a timer. If not, an alarm is generated.

[0059] Specifically, the system monitors raw material inventory data to scientifically plan production line capacity. For example, if the actual inventory is k and the manually uploaded next material arrival time is d, then the planned daily capacity is k / d, generating a management task that is limited to the next d days, with a daily capacity of k / d.

[0060] (2) When the billet waiting time and the tapping time are obtained from the MES system, the corresponding management task is generated. The management task is limited to reducing the power of the hydraulic station to the minimum during the waiting time.

[0061] The minimum power setting can be set to keep one hydraulic pump drive motor running normally.

[0062] (3) Monitor the on-site data of key equipment on the production line, including voltage and current data. If abnormal on-site data of key equipment is detected, a management task is generated to reduce the power of the hydraulic station to the minimum.

[0063] S2. Estimate the theoretical number of hydraulic pumps required for production in the short term based on the management task.

[0064] Based on the management task generated in step S1, it is parsed, and the required power in the management task is converted into the theoretical number of hydraulic pumps according to the power (or production capacity) corresponding to the number of hydraulic pumps.

[0065] S3. Collect the actual number of hydraulic pumps operating on the production line, and adjust the actual number of hydraulic pumps operating on the production line to the theoretical number of hydraulic pumps by starting or stopping some hydraulic pump drive motors.

[0066] Maintain a hydraulic pump status list, which synchronously records the basic information of the hydraulic pumps currently in operation. Retrieve the number of hydraulic pumps currently in operation from the list and compare it with the theoretical number of hydraulic pumps. If the number of pumps in operation is greater than the theoretical number, shut down some hydraulic pump drive motors; the number of shut-down drive motors equals the difference between the actual and theoretical number of hydraulic pumps. If the number of pumps in operation is less than the theoretical number, start some hydraulic pump drive motors sequentially according to a preset start-up order; the number of started drive motors equals the difference between the theoretical and actual number of hydraulic pumps.

[0067] The control system connects to the controllers of each hydraulic pump drive motor, or connects to a PLC, to control the start and stop of each hydraulic pump drive motor. When shutting down a hydraulic pump drive motor, multiple hydraulic pump drive motors can be shut down simultaneously; when starting a hydraulic pump drive motor, they must be started one by one according to a pre-set starting sequence.

[0068] The system automatically records the duration of energy-saving control activation (the duration of non-fully activated state). In energy-saving mode, a prompt is displayed on the control panel next to the hydraulic station.

[0069] This method boasts a reasonable and comprehensive optimization scheme, advanced and mature technology, and utilizes a simple and easy-to-use "one-click energy saving" button developed by the automated first-level program. The hydraulic stations achieve an "optimal pump operation" mode, with some stations not only enabling single-pump operation during "standby" but also reducing pump operation during operation. A simple touch of the on-screen button achieves energy savings across the entire line. When resuming normal production, simply toggling the restore button allows each hydraulic station to start sequentially, restoring production conditions within 2 minutes.

[0070] After implementation, it can significantly reduce annual electricity costs, demonstrating excellent energy-saving effects. Simultaneously, it can extend the equipment's service life and reduce the procurement costs of hydraulic station spare parts, resulting in substantial economic and social benefits and demonstrating promising application prospects and widespread value.

[0074] The energy-saving execution unit 230 is used to collect the actual number of hydraulic pumps operating on the production line and adjust the actual number of hydraulic pumps operating on the production line to the theoretical number of hydraulic pumps by starting or stopping some hydraulic pump drive motors.
