[0002] High-temperature power rationing in industrial plants is a common energy regulation method that can effectively control the load of urban circuits. After obtaining the power rationing quota, the plant will effectively allocate it to ensure the normal operation of the plant's production lines and office areas as much as possible.

Therefore, there is an urgent need for a plant power regulation system for the special power consumption scenario of high-temperature power rationing, so that it can reasonably adjust and control the power consumption of a large number of refrigeration equipment in the plant under extreme power requirements.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] It should be noted that similar reference numerals or letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0019] Embodiment 1: Before explaining the plant energy regulation system, it is necessary to briefly explain the existing plant refrigeration system, such as Figure 2 As shown, a common factory refrigeration system includes multiple refrigeration links. Each refrigeration link includes at least one water tower, an air-conditioning main unit and multiple air-conditioning sub-units matched with the air-conditioning main unit. The air-conditioning main unit and the multiple air-conditioning sub-units are connected through multiple ventilation ducts. The water tower is used to dissipate heat for the air-conditioning main unit, thereby ensuring the refrigeration efficiency of the air-conditioning main unit.

[0020] like Figure 1 As shown, this embodiment provides a plant energy regulation system, the system comprising: A calculation module, the calculation module includes a meteorological data acquisition unit and a first calculation unit, wherein the meteorological data acquisition unit is connected to an external meteorological network and is used to obtain current temperature data. The temperature data will affect the cooling effect of the refrigeration equipment in the factory area, and is therefore an important basis for energy regulation; A regulating module, the regulating module comprising a data retrieval unit and a regulating unit, wherein the data retrieval unit is connected to the operation and maintenance database of the plant area and is used to retrieve the preset temperatures of multiple office areas in the plant area from the operation and maintenance data, the regulating unit is connected to multiple refrigeration links, office area temperature sensors and key channel temperature sensors, the refrigeration link comprises an air-conditioning host and multiple air-conditioning sub-units cooperating with the air-conditioning host, and the temperature control of a specific office area is achieved by controlling the switches of the multiple air-conditioning sub-units; Among them, the adjustment unit is used to adjust the operating power of multiple air-conditioning main units and air-conditioning sub-units matched with the air-conditioning main units based on the cooling level and population in and out of multiple office areas when the factory is power-limited, thereby reasonably adjusting the actual temperature of multiple office areas.

[0021] In this embodiment, the plant energy regulation system prioritizes the cooling needs of the plant sites. For some office areas with higher priorities, such as biological laboratories, the preset temperatures are not changed, and then the corresponding power consumption is adjusted in sequence according to the levels. For office areas with lower priorities, the operating power of the refrigeration equipment is appropriately reduced based on the flow of people, or even the corresponding refrigeration equipment is shut down, thereby achieving energy consumption regulation management while meeting the power limit requirements.

[0022] Secondly, there are significant differences in the spatial layout of factory areas and traditional office buildings. Therefore, it is not possible to uniformly schedule and adjust by simply raising the preset ambient temperature threshold. It is necessary to prioritize each area. For example, important production resource storage areas, important experimental areas, etc., are all areas that have rigid requirements on ambient temperature. Therefore, it is necessary to prioritize the stability of their temperature. Such places are classified as primary office areas in this embodiment, followed by conventional office areas, which are areas that can be appropriately adjusted.

[0023] Secondly, the activity patterns of personnel are quite different from those in traditional office buildings. Personnel are more active, that is, they move around a lot. Therefore, it is necessary to adjust the working temperature of the corresponding office area based on the activity level of personnel in the area.

[0024] Secondly, the above method for adjusting the actual temperature of multiple office areas includes step S100 and step S200.

[0025] Step S100, obtaining the current temperature data through the meteorological data acquisition unit and retrieving the target temperature of each office area in the factory through the data retrieval unit, and retrieving the first cooling power consumption corresponding to each office area and key channel per square in the operation and maintenance database based on the current temperature data and the target temperature, and calculating the total cooling power consumption corresponding to multiple office areas and multiple key channels based on the first cooling power consumption, the area of ​​the office area and the area of ​​the key channel; It should be noted that due to the architectural structure characteristics of the factory, there are large differences in the cooling power consumption per unit square corresponding to different office areas. For example, multi-story buildings and single-story buildings, the floor area of ​​the building, the location of the office area in the building, etc. will lead to certain differences in the cooling demand of the office areas under the same temperature conditions. It is necessary to conduct power consumption tests on each office area at different temperatures in advance, or to collect power consumption data of refrigeration equipment corresponding to each office area and key channels, and then obtain statistics on the cooling power consumption per unit square of each office area and key channel at different temperatures, and record them in the factory's operation and maintenance database.

[0026] Step S200, obtain the current power limit data, and retrieve the cooling power consumption quota in the power limit data. If the total cooling power consumption is greater than 115% of the cooling power consumption quota, adjust the operating power of multiple air-conditioning hosts and air-conditioning sub-units matched with the air-conditioning hosts based on the cooling levels and population in and out of multiple office areas, and then reasonably adjust the actual temperatures of multiple office areas. It should be noted that, in the case of no power limit, each office area in the factory is set with a target temperature and corresponding opening and closing time periods, so that the office areas and key channels are kept within a certain temperature range. However, the power consumption limitation caused by high temperature power limit will make it impossible to meet the cooling needs under normal circumstances. Therefore, it is necessary to meet them in turn according to the priority of the office areas, and eliminate some office areas and key channels with fewer people.

[0027] Secondly, the specific implementation method of adjusting the actual working temperature of multiple office areas based on the cooling levels and population inflow and outflow of multiple office areas in step S200 is: Step S210: acquiring target temperatures, office area areas, and weather data corresponding to multiple first-level office areas, and finding the second cooling power consumption corresponding to each first-level office area per square meter in the operation and maintenance database based on the target temperature and weather data corresponding to each first-level office area, and calculating the corresponding first-level cooling power consumption based on the second cooling power consumption corresponding to each first-level office area and the office area, and then calculating the first operation and maintenance power corresponding to the multiple first-level office areas; Step S220: obtaining current power-limiting data, and calculating a second operation and maintenance power threshold based on a difference between a cooling power consumption quota in the power-limiting data and the first operation and maintenance power; Step S230: acquiring monitoring images corresponding to a plurality of secondary office areas and monitoring images of a plurality of key channels in the first time period, and sequentially identifying the number of office workers corresponding to each secondary office area and the number of people passing through each key channel in the first time period, and eliminating a plurality of invalid key channels and secondary office areas based on a preset number threshold, thereby screening out a plurality of valid secondary office areas and valid key channels; Step S240, retrieve the maximum operating temperature thresholds corresponding to multiple valid secondary office areas and valid key channels, correct the maximum operating temperature thresholds corresponding to the valid secondary office areas based on the total lengths of the moving trajectories corresponding to multiple moving targets in the valid secondary office areas, and calculate the second operation and maintenance powers corresponding to the multiple valid secondary office areas and valid key channels based on the maximum operating temperature thresholds; It should be noted that the maximum working temperature threshold is the preset maximum working environment temperature and is written to the operation and maintenance server in advance. At the same time, the maximum working temperature threshold should be appropriately lowered for office areas with high human activity to improve the office experience.

[0028] Step S250: If the second operation and maintenance power is less than the second operation and maintenance power threshold, the corresponding operation instructions for the air conditioner host and the air conditioner slave are generated based on the maximum operating temperature thresholds corresponding to the multiple valid secondary office areas and the valid key channels.

[0029] Step S260: If the second operation and maintenance power is greater than or equal to the second operation and maintenance power threshold, based on the difference between the second operation and maintenance power threshold and the second operation and maintenance power, the maximum operating temperature threshold corresponding to the effective key channel in the non-direct sunlight orientation is increased or the operation of the air-conditioning host corresponding to the effective key channel is stopped, thereby reducing the second operation and maintenance power until it is lower than the second operation and maintenance power threshold.

[0030] Secondly, the specific implementation method of increasing the maximum operating temperature threshold corresponding to the effective key channel in the non-direct sunlight orientation or stopping the operation of the air conditioner host and the air conditioner slave corresponding to the effective key channel based on the difference between the second operation and maintenance power threshold and the second operation and maintenance power in step S260 is: Step S261, obtaining the current time node, and calling the corresponding lighting parameters and the three-dimensional virtual model of the factory area, thereby obtaining at least one first wall surface that is not directly exposed to sunlight, constructing a first radiation zone based on the first wall surface, wherein the width of the first radiation zone is set based on the current temperature, and querying whether there is a valid key channel in the first radiation zone. If the proportion of the valid key channel in the first radiation zone is greater than 55%, it is determined to be a second key channel; Step S262: reduce or even shut down the operating power consumption of the air conditioner slave and / or the air conditioner host corresponding to the second key channel until the adjusted second operation and maintenance power is less than the second operation and maintenance power threshold.

[0031] Secondly, the specific implementation method of correcting the maximum operating temperature threshold corresponding to the effective secondary office area based on the total length of the movement tracks corresponding to the multiple moving targets in the effective secondary office area in step S240 is: Step S241: dispatch multiple surveillance videos from different angles in an effective secondary office area, identify the human targets in each surveillance video based on the shape-based image feature extraction algorithm, and eliminate repeated human targets in multiple surveillance videos based on scene coordinates and target human features, thereby obtaining the number of human targets in the effective secondary office area; Step S242: construct multiple moving point monitoring coordinates based on the road distribution in the valid secondary office area, and when the person target in the monitoring video moves to the corresponding moving point monitoring coordinates, mark the moving path corresponding to the person target as the first valid path; Step S243, obtaining multiple first valid paths collected in the first time period, and eliminating first valid paths whose lengths are less than a minimum threshold, thereby obtaining multiple second valid paths; Step S244: based on the end vector direction of each second valid path and the coordinates of the doorway of the valid secondary office area, eliminate the second valid paths used to indicate that the paths have left the valid secondary office area within the first time period, thereby obtaining a plurality of third valid paths; Step S245: Calculate the average activity path length corresponding to the average effective secondary office area based on the number of third effective paths and the total length of multiple third effective paths; Step S246: based on the fluctuation of the number of target people in the effective secondary office area in the first time period, calculate the average total number of people in the effective secondary office area in the first time period; Step S247: Calculate the first activity level of the effective secondary office area through a weighted algorithm based on the ratio between the number of the third effective paths and the average total number of people and the average activity path length; Step S248: Correct the maximum operating temperature threshold corresponding to the valid secondary office area based on the first activity level.

[0032] Effective activity tracks within the office area should meet the following requirements: 1. The moving distance within a certain period of time must reach the preset distance value to prevent misjudgment of activity due to small-scale activities at the workstation; 2. If you leave the office area during this period, it will be considered an invalid trajectory, that is, the activity trajectory of the person leaving will not be counted as an evaluation parameter for the activity of the office area.

[0033] Secondly, the implementation method of correcting the maximum operating temperature threshold corresponding to the effective secondary office area based on the activity level in step S248 is: Step S2481, retrieve the activity threshold corresponding to the current valid secondary office area from the operation and maintenance database, the activity threshold is determined based on the employee position table, and the employee position table can be used to determine the number of long-term residents corresponding to each office area, and then determine different numbers of people (activity thresholds corresponding to different office areas); Step S2482: If the first activity level is greater than the activity level threshold, the maximum operating temperature threshold corresponding to the effective secondary office area is lowered based on the difference between the first activity level and the activity level threshold.
