[0066] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0067] The industrial production equipment start-stop control method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown is illustrated. Server 102 communicates with industrial equipment 104. A data storage system can store the data that server 102 needs to process. The data storage system can be integrated onto server 102 or placed in the cloud or on another network server. Server 102 can communicate with industrial equipment 104 through a smart gateway. Server 102 obtains the basic energy data of industrial equipment 104 and determines a target duration based on the basic energy data. The target duration is the duration during which the cumulative electricity consumption of the target production equipment is the same in both continuous start-up mode and stop-start mode. When the current non-production time of the target production equipment exceeds the target time, server 102 determines a first total power consumption resource based on the electricity unit price data within a preset control period and the first cumulative power consumption of the target production equipment in continuous start mode. It then determines a second total power consumption resource based on the electricity unit price data within the preset control period and the second cumulative power consumption of the target production equipment in stop-start mode. Finally, based on the first and second total power consumption resource amounts, a target control mode is determined from the continuous start mode and the stop-start mode. This target control mode is then sent to industrial equipment 104 to control the start / stop of the target production equipment. Server 102 can be implemented using a standalone server or a server cluster consisting of multiple servers. Industrial equipment 104 can be a reflow oven or surface mount equipment, etc., in industrial production equipment.

[0068] In one embodiment, such as Figure 2 As shown, a method for starting and stopping industrial production equipment is provided, which can be applied to... Figure 1 Taking server 102 as an example, the explanation includes the following steps:

[0069] S201: Obtain the target duration, which is the duration during which the cumulative power consumption of the target production equipment is the same in both continuous start-up mode and stop-start mode.

[0070] Continuous start-up mode refers to the industrial production equipment being continuously powered on when it is not in production mode. Stop-start mode refers to the industrial production equipment being intermittently powered on when it is not in production mode, meaning the power is cut off for a period of time before being reconnected. When the target production equipment is in continuous start-up mode, the current power consumption of the target production equipment is measured at regular intervals from the initial moment to obtain the cumulative power consumption in continuous start-up mode. When the target production equipment is in stop-start mode, the current power consumption is measured at the same time intervals from the initial moment to obtain the cumulative power consumption in stop-start mode. At any given moment, the cumulative power consumption of the target production equipment in continuous start-up mode and the cumulative power consumption in stop-start mode are the same. The time length from the initial moment to this point of equality is defined as a target duration. In theory, when the target production equipment is in a non-production state for a sufficiently long time, there will be multiple moments when the cumulative power consumption of the target production equipment in continuous start mode is the same as the cumulative power consumption of the target production equipment in stop-start mode. However, considering the actual application requirements, the target production equipment will not be in a non-production state for a long time. Therefore, we only consider the first moment when the cumulative power consumption of the target production equipment in continuous start mode is the same as the cumulative power consumption of the target production equipment in stop-start mode.

[0071] S202: When the current non-production duration of the target production equipment is longer than the target duration, the first total amount of electricity resources is determined based on the electricity unit price data within the preset control cycle and the first cumulative electricity consumption of the target production equipment in continuous start-up mode.

[0072] Specifically, when the current non-production time of the target production equipment is less than or equal to the target time, in order to ensure that the target production equipment can quickly enter the production state, the target production equipment is usually controlled in continuous start mode. When the current non-production time of the target production equipment is greater than the target time, in order to reduce the power consumption cost of the target production equipment, the total power consumption of the target production equipment in continuous start mode and stop-start mode within a preset period is calculated to determine the target control mode.

[0073] The electricity unit price data refers to different electricity consumption periods and their corresponding electricity unit prices. Electricity consumption periods generally include peak periods, off-peak periods, and valley periods, and the corresponding electricity unit prices include peak period electricity unit prices, off-peak period electricity unit prices, and valley period electricity unit prices. Specifically, peak periods are generally from 5 PM to 9 PM, while off-peak periods are generally from 10 PM to 6 AM the next day. Based on the electricity unit prices for different periods and the power consumption of the target production equipment, the total electricity consumption of the target production equipment in continuous start-up mode is calculated, i.e., the total amount of the first electricity resource consumption.

[0074] S203: Based on the electricity unit price data within the preset control period and the second cumulative electricity consumption of the target production equipment in the stop-start mode, determine the second total amount of electricity consumption resources.

[0075] The calculation method for the second total amount of electricity consumption resources is similar to that for the first total amount of electricity consumption resources. The total amount of electricity consumption resources for the target production equipment in the stop-start mode is calculated based on the electricity consumption of the target production equipment in different electricity consumption periods and the electricity price per unit during those periods. This is the second total amount of electricity consumption resources.

[0076] S204: Based on the first total power consumption and the second total power consumption, determine the target control mode from the continuous start mode and the stop-start mode, and control the stop-start of the target production equipment based on the target control mode.

[0077] Specifically, based on the relationship between the first total power consumption and the second total power consumption, a target control mode is determined from the continuous start mode and the stop-start mode. When the first total power consumption is less than the second total power consumption, the target control mode is determined to be the continuous start mode. When the first total power consumption is greater than or equal to the second total power consumption, the target control mode is determined to be the stop-start mode.

[0078] In the above-mentioned industrial production equipment start-up method, by obtaining the duration for which the cumulative power consumption of the target production equipment is the same in both continuous start-up mode and stop-start mode, when the current non-production duration of the target production equipment is greater than the target duration, the total power consumption of the target production equipment in both continuous start-up mode and stop-start mode is calculated respectively. Based on the first total power consumption and the second total power consumption, the target control mode is determined from the continuous start-up mode and the stop-start mode. The stop-start of the target production equipment is controlled based on the target control mode, which can accurately control the start-stop state of the target production equipment and reduce the power consumption of the target production equipment.

[0079] In one embodiment, such as Figure 3 As shown, the target acquisition time mentioned above includes:

[0080] S301: Accumulate the power consumption of the target production equipment in continuous start-up mode from the initial moment.

[0081] The server communicates with the target production equipment through a smart gateway to collect temperature data. Assuming a collection frequency of once every 15 minutes, the server calculates the electricity consumption of the target production equipment for 15 minutes per day in continuous start-up mode when the equipment is not in production operation. The specific calculation formula is as follows:

[0082] Ep(t) = EPz(t) - EPz(t-15)

[0083] Where Ep(t) represents the energy consumption in 15 minutes at time t; EPz(t) represents the total positive active energy (cumulative value) at time t; and EPz(t-15) represents the total positive active energy (cumulative value) at time t-15.

[0084] S302: Accumulate the power consumption of the target production equipment in stop-start mode from the initial moment.

[0085] The method for accumulating the electricity consumption of the target production equipment in the stop-start mode is similar to that in the continuous start mode. When the target production equipment is in a non-production condition, the electricity consumption of the target production equipment in the stop-start mode for 15 minutes a day is calculated.

[0086] S303: Obtain the target time when the cumulative power consumption in continuous start mode is equal to the cumulative power consumption in stop-start mode.

[0087] Within a single start-stop cycle, the power consumption of the target production equipment is EPa(t). In continuous start-up mode, the power consumption of the target production equipment every 15 minutes is Ep(t). Therefore, in continuous start-up mode, the power consumption per hour is Ep(t) × 4. When the cumulative power consumption in continuous start-up mode equals the cumulative power consumption in start-stop mode, it can be expressed by the formula: EPa(t) = (Ep(t) × 4) × T. Thus, after a time period T, the cumulative power consumption in continuous start-up mode equals the cumulative power consumption in start-stop mode.

[0088] S304: Use the interval between the target time and the initial time as the target duration.

[0089] The target duration is T, which can be calculated using the formula above.

[0090] In this embodiment, by accumulating the power consumption of the target production equipment in continuous start mode from the initial moment and accumulating the power consumption of the target production equipment in stop-start mode, the accumulated power consumption in continuous start mode can be obtained, and the target moment when the accumulated power consumption in stop-start mode is equal can be accurately obtained, thereby accurately controlling the start-stop state of the target production equipment based on the target moment.

[0091] In one embodiment, such as Figure 4 As shown, the steps for determining the first cumulative electricity consumption include:

[0092] S401: Within a preset control cycle, acquire multiple power data of the target production equipment in continuous start-up mode at preset time intervals.

[0093] The preset control cycle refers to a start-stop cycle in which the target production equipment is in stop-start mode. The preset duration interval can be set according to actual needs, such as 15 minutes. Specifically, the power data can be obtained by measuring the multi-function meter. The server communicates with the multi-function meter through network equipment to obtain multiple power data.

[0094] S402: Calculate the power consumption of the target production equipment based on multiple power consumption data.

[0095] The electricity consumption is the difference between the current electricity consumption data and the initial electricity consumption data. It is calculated using the electricity consumption data on the multi-function meter and the preset multiplier corresponding to the multi-function meter. The preset multiplier refers to the multiplier of the current transformer matched with the electricity meter, also known as the transformation ratio, current (voltage) ratio, or current (voltage) ratio. It is a scaled-down ratio. The actual electricity consumption is equal to the meter reading multiplied by the multiplier.

[0096] S403: Calculate the sum of multiple electricity consumption values ​​to obtain the first cumulative electricity consumption of the target production equipment in continuous start-up mode.

[0097] Among them, the multiple power consumptions within the preset control period represent the power consumption within different time periods, and the sum of the values ​​of the multiple power consumptions is the first cumulative power consumption of the target production equipment in continuous start-up mode within the preset control period.

[0098] In this embodiment, by acquiring multiple power consumption data of the target production equipment in continuous start mode at preset time intervals within a preset control cycle, and calculating multiple power consumptions of the target production equipment based on the multiple power consumption data, and then calculating the sum of the multiple power consumption values, the first cumulative power consumption of the target production equipment in continuous start mode can be accurately obtained, providing a data basis for subsequently determining the target control mode from the continuous start mode and the stop-start mode.

[0099] In one embodiment, such as Figure 5 As shown, the preset control cycle is one of the shutdown / start cycles in the shutdown / start mode. The steps for determining the second cumulative power consumption include:

[0100] S501: When the target production equipment is in stop-start mode, acquire the periodic power data of each preset control cycle within multiple preset control cycles.

[0101] When the target industrial equipment is in stop-start mode, in order to avoid mutual interference during each stop-start cycle, the average value of each preset control cycle is calculated. Therefore, the cycle power data of each preset control cycle within multiple preset control cycles is obtained. In order to simplify the calculation, the number of preset control cycles should not be too many.

[0102] S502: Calculate the electricity consumption for each cycle based on the electricity consumption data for each cycle.

[0103] The system obtains cycle power data for each preset control cycle through a multi-functional meter, and calculates the corresponding power consumption for each cycle based on the cycle power data and a preset multiplier.

[0104] S503: Calculate the average value of electricity consumption in each cycle to obtain the second cumulative electricity consumption of the target production equipment in the stop-start mode.

[0105] The average electricity consumption in each cycle is used as the second cumulative electricity consumption when the target production equipment is in stop-start mode.

[0106] In this embodiment, when the target production equipment is in the stop-start mode, the cycle power data of each preset control cycle within multiple preset control cycles is obtained, and the power consumption of each cycle is calculated based on the power consumption data of each cycle, thereby calculating the average value of the power consumption of each cycle. This can accurately obtain the second cumulative power consumption of the target production equipment in the stop-start mode, providing a data basis for subsequently determining the target control mode from the continuous start mode and the stop-start mode.

[0107] In one embodiment, the aforementioned first cumulative electricity consumption includes first electricity consumption in multiple different periods. Based on the electricity unit price data within a preset control period and the first cumulative electricity consumption of the target production equipment in continuous start-up mode, the total amount of the first power consumption resource is determined, including: obtaining the first electricity consumption of each target period within each preset control period; the target periods include peak periods, off-peak periods, and valley periods; obtaining the electricity unit price corresponding to each target period in the electricity unit price data; obtaining the first peak period power consumption resource based on the product of the first electricity consumption of the peak period and the corresponding electricity unit price of the peak period; and obtaining the first peak period power consumption resource based on the product of the first electricity consumption of the peak period and the corresponding electricity unit price of the peak period. The first peak-period power consumption resource is obtained by multiplying the electricity unit price of the first peak period; the first neutral-period power consumption resource is obtained by multiplying the first electricity consumption of the neutral period and the corresponding electricity unit price of the neutral period; the first valley-period power consumption resource is obtained by multiplying the first electricity consumption of the valley period and the corresponding electricity unit price of the valley period; the first peak-period power consumption resource, the first neutral-period power consumption resource, and the first valley-period power consumption resource are added together to obtain the initial total first power consumption resource; multiple initial total first power consumption resources corresponding to multiple preset control cycles are obtained; the minimum value of the multiple initial total first power consumption resources is determined as the total first power consumption resource.

[0108] The first cumulative electricity consumption includes the first electricity consumption during peak periods, the first electricity consumption during off-peak periods, the first electricity consumption during normal periods, and the first electricity consumption during valley periods. The electricity price data includes the electricity price during peak periods, the electricity price during off-peak periods, the electricity price during normal periods, and the electricity price during valley periods. This electricity price data is usually obtained by staff from the information published on the power grid platform and manually stored in the server.

[0109] The calculation is as follows: First peak period electricity consumption = First peak period electricity consumption × Peak period electricity price; First off-peak period electricity consumption = First peak period electricity consumption × Peak period electricity price; First neutral period electricity consumption = First neutral period electricity consumption × Neutral period electricity price; First valley period electricity consumption = First valley period electricity consumption × Valley period electricity price. Therefore, the initial total first electricity consumption = First peak period electricity consumption + First peak period electricity consumption + First neutral period electricity consumption + First valley period electricity consumption. To ensure the accuracy of the total first electricity consumption, the initial total first electricity consumption is obtained multiple times according to a preset control cycle. The final total first electricity consumption is then calculated based on this initial total, and the smallest initial total first electricity consumption among the multiple totals is taken as the final total first electricity consumption.

[0110] In this embodiment, by acquiring the first electricity consumption of each target period within each preset control cycle and acquiring the electricity unit price corresponding to each target period in the electricity unit price data, the first electricity consumption resource of each target period is calculated to obtain the initial total amount of the first electricity consumption resource. This is then calculated multiple times to determine the total amount of the first electricity consumption resource from multiple initial total amounts of the first electricity consumption resource. This allows for accurate calculation of the total amount of the first electricity consumption resource, providing a data basis for subsequently determining the target control mode from the continuous start mode and the stop-start mode.

[0111] In one embodiment, the aforementioned second cumulative electricity consumption includes second electricity consumption for multiple different periods. Based on the electricity unit price data within a preset control period and the second cumulative electricity consumption of the target production equipment in a stop-start mode, the total amount of second power consumption resources is determined, including: acquiring the second electricity consumption for each target period within each preset control period; obtaining the second peak-period power consumption resources by multiplying the second electricity consumption of the peak period by the corresponding electricity unit price; obtaining the second peak-period power consumption resources by multiplying the second electricity consumption of the peak period by the corresponding electricity unit price; and obtaining the second peak-period power consumption resources by multiplying the second electricity consumption of the off-peak period by the corresponding electricity unit price; and obtaining the second peak-period power consumption resources by multiplying the second electricity consumption of the off-peak period by the corresponding electricity unit price. The second flat-period power consumption resource is obtained by multiplying the second electricity consumption during the off-period period and the corresponding electricity price during the off-period period; the second off-period power consumption resource is obtained by multiplying the second electricity consumption during the off-period period and the corresponding electricity price during the off-period period; the second peak-period power consumption resource, the second flat-period power consumption resource, and the second off-period power consumption resource are added together to obtain the initial total amount of the second power consumption resource; multiple initial total amounts of the second power consumption resource corresponding to multiple preset control cycles are obtained; the minimum value of the multiple initial total amounts of the second power consumption resource is determined as the total amount of the second power consumption resource.

[0112] The second cumulative electricity consumption includes the second electricity consumption during peak periods, the second electricity consumption during off-peak periods, the second electricity consumption during normal periods, and the second electricity consumption during valley periods. Then, the second electricity consumption resources corresponding to each target period are calculated based on the electricity unit price obtained from the electricity unit price data for each target period.

[0113] Specifically, the second peak period electricity consumption resource = peak period second electricity consumption × peak period electricity price; the second high-peak period electricity consumption resource = peak period second electricity consumption × peak period electricity price; the second flat period electricity consumption resource = flat period second electricity consumption × peak-flat period electricity price; and the second low-peak period electricity consumption resource = low-peak period second electricity consumption × low-peak period electricity price. Therefore, the initial total second electricity consumption resource = second peak period electricity consumption resource + second high-peak period electricity consumption resource + second flat period electricity consumption resource + second low-peak period electricity consumption resource. To ensure the accuracy of the total second electricity consumption resource, the initial total second electricity consumption resource is obtained multiple times according to a preset control cycle. The final total second electricity consumption resource is then calculated based on this initial total, and the smallest initial total is taken as the final total second electricity consumption resource.

[0114] In this embodiment, by acquiring the second electricity consumption for each target period within each preset control cycle and acquiring the electricity unit price corresponding to each target period in the electricity unit price data, the second electricity consumption resources for each target period are calculated respectively to obtain the initial total amount of the second electricity consumption resources. Multiple calculations are performed to determine the total amount of the second electricity consumption resources from multiple initial total amounts of the second electricity consumption resources. This can accurately calculate the total amount of the second electricity consumption resources, providing a data basis for subsequently determining the target control mode from the continuous start mode and the stop-start mode.

[0115] In one embodiment, determining the target control mode from the continuous start mode and the stop-start mode based on the first total power consumption and the second total power consumption includes: if the first total power consumption is less than the second total power consumption, then the continuous start mode is selected as the target control mode; if the first total power consumption is greater than the second total power consumption, then the stop-start mode is selected as the target control mode.

[0116] Specifically, when the total first power consumption is less than the total second power consumption, it means that the target production equipment consumes less power in the continuous start mode, so the continuous start mode is selected as the target control mode. When the total first power consumption is greater than the total second power consumption, it means that the target production equipment consumes less power in the stop-start mode, so the stop-start mode is selected as the target control mode.

[0117] In this embodiment, by determining the target control mode from the continuous start mode and the stop-start mode based on the first total power consumption resource and the second total power consumption resource, the start-stop state of the target production equipment can be precisely controlled, so that the power consumption of the target production equipment is smaller in non-production conditions, thereby reducing the power consumption of the target production equipment.

[0118] In another embodiment, such as Figure 6 As shown, a method for starting and stopping a reflux furnace is provided, which includes the following steps:

[0119] Step 1: Obtain the basic energy data for the reflow oven: The sources of the basic energy data for the reflow oven are as follows... Figure 7 As shown, the server communicates with the reflow oven equipment and the multi-function meter through a smart gateway to obtain the reflow oven's power consumption data, temperature data, and peak and off-peak electricity price data.

[0120] The data includes: Electricity consumption data: Three-phase current transformers and multi-function meters are installed in the reflow oven's distribution cabinet. These meters contain electricity consumption parameters. The data is collected via a smart gateway and transmitted to the system through an IoT platform. Data is collected every 15 minutes. Temperature data: A new smart gateway communicates with the reflow oven to collect temperature data, which is also transmitted to the system through an IoT platform. Temperature data is collected every 15 minutes. Peak, off-peak, and valley electricity price data: This includes peak time periods, peak-hour electricity prices, off-peak time periods, off-peak electricity prices, valley time periods, and valley electricity prices. This data is obtained from publicly available electricity prices published by the power grid and manually entered into the system once a month.

[0121] Step Two: Based on the reflow oven's basic energy data, calculate the 15-minute power consumption trend of the reflow oven under a continuous start-up strategy during non-production operation, and the corresponding temperature change trend. Taking a 60kW reflow oven as an example, the correlation trend chart of 15-minute power consumption and temperature is shown below. Figure 8 As shown.

[0122] Step 3: Based on the reflow oven's basic energy data, calculate the daily electricity consumption trend during the shutdown and restart strategy under non-production conditions, and the corresponding reflow oven temperature change trend. Taking a 60kW reflow oven as an example, output a 15-minute correlation trend chart between electricity consumption and reflow oven temperature, as shown below. Figure 9 As shown.

[0123] Step 4: Under non-production conditions of the reflow oven, calculate the time required for the cumulative power consumption of the reflow oven in the continuous start-up strategy to equal the cumulative power consumption of the reflow oven in the shutdown and restart strategy, and obtain the first target time.

[0124] Step 5: When the non-production time of the reflow oven is less than or equal to the first target time, output the continuous start-up strategy.

[0125] Step Six: When the non-production time of the reflow oven exceeds the first target time, calculate the minimum electricity cost based on the cumulative electricity consumption of the reflow oven in the shutdown and restart strategy and the electricity price during peak and off-peak periods. When the minimum electricity cost is greater than or equal to the cumulative electricity cost of the reflow oven in the continuous start strategy, output the continuous start strategy; when the minimum electricity cost is lower than the cumulative electricity cost of the reflow oven in the continuous start strategy, output the shutdown and restart strategy for the reflow oven.

[0126] In this embodiment, based on energy data such as temperature, power consumption, and electricity cost of the reflow oven equipment, the temperature, power consumption, and electricity cost trends of the reflow oven under different start-up and shutdown strategies during non-production conditions are analyzed. The correlation between temperature, power consumption, and electricity cost is analyzed, and combined with equipment power consumption optimization and electricity cost optimization models, start-up and shutdown optimization strategies are provided for the reflow oven to achieve the goal of energy saving and consumption reduction of the reflow oven equipment.
