Obviously, the drawings described below are only some embodiments of the present application, and for those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative work.

[0068] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0069] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0070] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0071] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of an energy management method shown in an exemplary embodiment of the present application. Figure 1 As shown, in an exemplary embodiment, the energy management method includes steps S110 to S150, which are described in detail as follows:

[0072] Step S110, when the first production line of the factory needs to produce the first product, determine the quantity of the first product produced by the first production line within a preset period;

[0073] Step S120, obtaining the energy consumption required to produce one unit of the first product;

[0074] Step S130, determining the predicted energy consumption of the first production line within the preset period based on the energy consumption required to produce one of the first products and the quantity of the first products;

[0075] Step S140, obtaining the actual energy consumption of the first production line in the preset period;

[0076] Step S150, when the deviation between the actual energy consumption and the predicted energy consumption meets a preset energy consumption abnormality condition, executing an alarm process.

[0077] In step S110, the first production line can be any production line in the factory. When the first production line needs to produce the first product, the number of first products that can be produced in the preset period can be calculated based on the production rhythm of the first production line. Among them, the preset period can be determined based on the frequency of abnormal energy consumption judgment of the production line, and the frequency of abnormal energy consumption judgment of the production line can be determined based on the importance of the production line and the products to be produced. For example, when the importance of the product to be produced and the production line is high, the judgment frequency can be set higher and the above preset period can be shorter (for example, every minute is used as a preset period to perform energy consumption abnormality detection); when the importance of the product to be produced and the production line is relatively low, the judgment frequency can be set relatively low, and the above preset period can be set longer (for example, every hour is used as a preset period to perform energy consumption abnormality detection).

[0078] In step S120, the energy consumption required to produce one of the first products refers to the energy consumption required for one production line to produce one of the first products. In some embodiments, the energy consumption required for any production line to produce the same product can be regarded as the same value. In other embodiments, due to certain differences in the performance and aging of the production equipment in each production line, the energy consumption required to produce the same product may be different. Based on this, the energy consumption required for each production line to produce the same product can be determined separately, for example, the energy consumption required for the first production line to produce one of the first products and the energy consumption required for the second production line to produce one of the first products can be determined. When it is necessary to determine whether the energy consumption of the first production line is abnormal, the energy consumption required for the first production line to produce one of the first products can be obtained.

[0079] It is worth mentioning that the production line mainly consumes electricity when producing products. Based on this, the energy consumption of the production line in this application can generally be regarded as the power consumption of the production line. To determine the power consumption of a production line in producing a product, the power consumption can be estimated based on the production situation of each line recorded on the production management system. For example, based on the number of Class 001 products produced by the production line in a specified time period and the power consumption of producing Class 001 products in the above-mentioned specified time period, the average power consumption for producing a Class 001 product can be used as the power consumption for producing a Class 001 product; or, directly based on the above-mentioned production situation, the power consumption for producing a Class 001 product can be given based on expert experience.

[0080] In step S140, the production line is provided with an energy collection unit, and the actual energy consumption of the first production line within the above-mentioned preset period can be obtained based on the energy collection unit provided on the first production line.

[0081] In step S150, an abnormal energy consumption condition is met, for example, the difference between the actual energy consumption and the predicted energy consumption is outside the preset normal difference range, or the percentage between the actual energy consumption and the predicted energy consumption is outside the preset normal percentage range, etc. In the case where the deviation between the actual energy consumption and the predicted energy consumption meets the preset abnormal energy consumption condition, an alarm process is executed. Execution of the alarm process includes at least one of the following: popping up an alarm message for alarm, executing a telephone alarm, sending a message reminder to a related application on the server, and sending an email reminder to a related staff member.

[0082] This application combines the production data of the product to determine the predicted energy consumption of the production line, so as to judge whether the actual energy consumption of the production line is abnormal, which is conducive to improving the accuracy of the judgment.

[0083] Optionally, when the second production line is not open and it is detected that the energy consumption of the second production line is greater than a first preset threshold, the alarm process is executed;

[0084] If no feedback information is received from the staff based on a value greater than the first preset threshold value after exceeding the preset time period, the production equipment in the second production line is controlled to be shut down.

[0085] In this implementation, the energy consumption of the second production line may be the power consumption of the second production line. The feedback information may be that the staff shuts down the production equipment of the second production line, or determines that the second production line needs to be opened, or indicates that there is no relevant abnormality.

[0086] In the embodiment of the present application, when it is detected that the energy consumption of the unopened production line exceeds the above-mentioned first preset threshold, an alarm notification is issued. If the staff does not handle it within the preset time, the relevant equipment will be automatically shut down, which is beneficial to improving the safety of the production line.

[0087] In some embodiments, the operation status can be monitored in conjunction with the production system. If the production system shows that the production line is currently producing product No. 001, but no operation signal (such as power usage signal, or production signal of product No. 001) is collected for a long time, then relevant personnel can be notified to handle the issue.

[0088] Optionally, the energy management method is executed by an energy management system, which is communicatively connected to a plurality of energy collection units, and the plurality of energy collection units are respectively installed on energy-consuming units at various levels in the factory area. The energy management system is used to monitor the energy consumption data of the energy-consuming units at various levels through the plurality of energy collection units.

[0089] In this embodiment, multiple energy collection units are respectively installed on energy consumption units at various levels in the plant area. The energy consumption units in the plant area are diverse, mainly including water, electricity, gas and oil units. Based on the diversity of energy consumption units in the plant area, the multiple energy collection units may include an electric power collection unit for collecting power consumption, a water consumption data collection unit for collecting water consumption, a gas consumption data collection unit for collecting gas consumption, and an oil consumption data collection unit for collecting oil consumption.

[0090] Taking the power consumption unit as an example, the power collection unit of this embodiment can be respectively set up in the factory area, transformers for processing and converting electrical parameters, departments, workshops, production lines in workshops, power consumption equipment in production lines, and other large power consumption equipment (such as air conditioning units and air compressors).

[0091] Taking the water use unit as an example, the water use data collection unit of this embodiment can be respectively set up in the factory area and the main water use area (such as office buildings and fire water use areas), etc.

[0092] This embodiment refines the energy collection unit and sets it on the energy-consuming units at each level respectively, so that the energy consumption of the energy-consuming units at each level can be monitored, which is beneficial to improving energy safety.

[0093] In some embodiments, the annual energy-saving target threshold of the factory (including water, electricity, gas and oil, etc.) can be obtained, and based on the corresponding energy collection units set up in the factory, the real-time total energy consumption of the factory within the year can be obtained. When the real-time total energy consumption is greater than the above-mentioned annual energy-saving target threshold (power consumption exceeds the annual power-saving target threshold or water consumption exceeds the annual water-saving target threshold, etc.), the alarm process is executed.

[0094] In some embodiments, the annual energy-saving target threshold of each department (including water, electricity, gas and oil, etc.) can also be obtained, and based on the corresponding energy collection units set up by each department, the real-time total energy consumption of each department within the year can be obtained. When the real-time total energy consumption of a department is greater than its corresponding annual energy-saving target threshold (power consumption exceeds the annual power-saving target threshold or water consumption exceeds the annual water-saving target threshold, etc.), the alarm process is executed.

[0095] Optionally, the method further comprises:

[0096] Receiving first energy usage data of M first energy consuming units sent by M first energy collection units, wherein the M first energy consuming units are all energy consuming units of the Nth level, and M and N are positive integers;

[0097] receiving second energy usage data of K second energy consuming units sent by K second energy collection units, wherein the K second energy consuming units are all energy consuming units of the (N+1)th level, the energy consuming units of the Nth level are used to transmit energy to the energy consuming units of the (N+1)th level, and K is a positive integer;

[0098] determining whether a deviation between the first energy usage data and the second energy usage data satisfies a preset loss abnormality condition;

[0099] When the deviation between the first energy usage data and the second energy usage data meets a preset loss abnormality condition, the alarm process is executed.

[0100] The upper-level energy-consuming unit is used to transmit energy to the lower-level energy-consuming unit. For example, the factory area is used to transmit water, electricity and other energies to each power-consuming department, and the production line is used to transmit electric energy to each power-consuming equipment of the production line. The energy consumption data of the energy-consuming unit at the Nth level is supposed to be equal to the sum of the energy consumption data of the energy-consuming unit at the (N+1)th level, but in fact there will be a certain line loss. For example, the power collection value of the upper-level meter is the sum of the power collection values ​​of each lower-level meter, but in actual circumstances, there may be reasonable differences due to line losses; but if the difference is too large, it means that there is power consumption outside the control, such as random connection of lines. If the energy transmission pipeline between the Nth level and the (N+1)th level is abnormal, there is an abnormal loss, so that the deviation between the first energy consumption data and the second energy consumption data meets the preset loss abnormality condition. Among them, the abnormal loss condition is met, for example, exceeding the preset normal loss range.

[0101] It is worth mentioning that this embodiment is for explaining the abnormal loss determination between energy consumption units of adjacent levels. In other embodiments, abnormal loss determination between energy consumption units of non-adjacent levels may also be performed, and the specific implementation method thereof may refer to the above embodiment. Since the line between energy consumption units of non-adjacent levels becomes longer, the normal loss range may be correspondingly expanded.

[0102] In this embodiment, abnormal loss is determined and an alarm is issued in the event of abnormal loss, which is beneficial to improving factory safety.

[0103] Optionally, the method further comprises:

[0104] Receiving energy consumption data of a third energy consuming unit at a first moment sent by a third energy collection unit, wherein the third energy consuming unit is any energy consuming unit among the energy consuming units at each level;

[0105] receiving energy consumption data of the third energy consumption unit at a second moment sent by the third energy collection unit;

[0106] Determining whether a deviation between the energy consumption data at the second moment and the energy consumption data at the first moment satisfies a preset abnormal energy consumption growth condition;

[0107] When the deviation between the energy usage data at the second moment and the energy usage data at the first moment meets the preset abnormal energy consumption growth condition, the alarm process is executed.

[0108] In this implementation, the second moment is the moment after the first moment. By determining the deviation between the energy consumption data at the second moment and the energy consumption data at the first moment, it is possible to determine whether the energy consumption growth is abnormal. In the event of an abnormality, an alarm is issued, which is conducive to promptly reminding the staff to take corresponding measures.

[0109] Optionally, the method further comprises:

[0110] Obtaining power-limited loads corresponding to the plant area at different time periods;

[0111] Receiving the power load of the plant area sent by the target power collection unit according to a preset frequency;

[0112] When it is detected that the power load of the factory area in a first time period is continuously greater than the power limit load corresponding to the first time period, power is cut off for target power equipment in a target area of ​​the factory area, wherein the first time period is any one of the different time periods.

[0113] In some embodiments, when it is detected that the power load of the factory area in the first time period continues to be greater than the power limit load corresponding to the first time period, an alarm process can be executed at the same time.

[0114] Due to the high temperature in summer and the low temperature in winter, the power demand increases, which may lead to power rationing in the factory area. This embodiment can determine whether the power load of the factory area in the corresponding period continues (the duration can be set) to exceed the corresponding limited load according to the power rationing load of the factory area in different periods, and if it exceeds, the target power equipment in the target area is powered off to meet the power rationing requirements.

[0115] The target electrical equipment may be an auxiliary electrical equipment, such as an air conditioner.

[0116] Among them, the target area can be divided according to the importance of each area, for example, divided into the first area, the second area, the third area and the fourth area with gradually increasing importance, etc. When it is detected that the power load of the factory area in the first time period continues to be greater than the power limit load corresponding to the first time period, the target power equipment in the first area is firstly powered off; after the target power equipment in the first area is powered off, if the power load is still greater than the power limit load corresponding to the first time period, the target power equipment in the second area can be powered off. In some embodiments, some equipment can also be set as power equipment that can never be powered off. When it is impossible to provide power to the power equipment that can never be powered off due to power limiting, the emergency power supply is started.

[0117] Optionally, the method further comprises:

[0118] Receive the air pressure value of the nitrogen outlet sent by the air pressure sensor, where the nitrogen outlet is an outlet for multiple nitrogen generators to output nitrogen to the outside;

[0119] When the pressure value of the nitrogen outlet is greater than a second preset threshold, controlling at least one nitrogen generator in an on state to be turned off;

[0120] When the pressure value of the nitrogen outlet is less than a third preset threshold, at least one nitrogen generator in a closed state is controlled to be turned on.

[0121] The above-mentioned multiple nitrogen generators are networked and output nitrogen together based on the nitrogen outlet. The nitrogen outlet is equipped with a pressure sensor, and the pressure value of the nitrogen outlet can be detected based on the pressure sensor. As an example, a programmable logic controller (PLC) can be installed to control the valves of the above-mentioned multiple nitrogen generators.

[0122] This embodiment can monitor the air pressure value of the nitrogen outlet. When the air pressure value of the nitrogen outlet is greater than the second preset threshold value, at least one nitrogen generator in the turned-on state is automatically controlled to be turned off; when the air pressure value of the nitrogen outlet is less than the third preset threshold value, at least one nitrogen generator in the turned-off state is automatically controlled to be turned on, which is conducive to achieving the best energy-saving state.

[0123] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
