[0017] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0019] Reference Figure 1 , which is a flow chart of a method for controlling clean room energy saving with an AI algorithm proposed by the present invention, comprising the following steps: S1, collects real-time environmental parameters and equipment power consumption data through temperature and humidity sensors, cleanliness monitors, dust particle collectors and smart meters deployed in the clean room; S2, associating the real-time environmental parameters, the equipment power consumption data and the production scheduling information to generate a dynamic control strategy; S3, based on the real-time environmental parameters, the equipment power consumption data, the dynamic control strategy and the historical energy consumption data, the start and stop strategy of the fan filter unit is calculated through the deep learning model, and the corresponding adjustment operation is performed.
[0020] As described in step S1 above, the real-time temperature and humidity fluctuations in the clean room are monitored by the temperature and humidity sensors deployed in the clean room to ensure compliance with the production process requirements; the cleanliness level is monitored in real time by a laser particle counter (such as ≥0.3μm particle concentration); the dust particle catcher is used to detect the particulate content in the air to assist in evaluating the cleanliness, and the dust particle catcher can capture particles with a particle size range of 0.5 microns or more; the smart meter is used to collect equipment power consumption data in real time, including fan FFU energy consumption (recording power consumption in different operating modes at full speed, half speed, and off), fresh air system dynamic energy consumption (monitoring real-time power consumption when valve opening changes), and filter additional energy consumption (collecting power consumption of the filter equipment required to maintain cleanliness). The Modbus / MQTT protocol is used to connect to the Internet of Things communication module, and the collected data is uploaded to the edge computing device in real time. The smart meter is integrated into the device controller to directly read the current and voltage parameters and calculate the power consumption.
[0021] As described in step S2 above, the real-time data collected in step S1 is associated with the planned capacity and operation period of the production scheduling system (MES / ERP) to generate a dynamic control strategy, which specifically includes: capacity period division, high capacity period corresponds to full production or overload production plan (such as chip manufacturing peak period), and cleanliness priority must be guaranteed; low capacity period corresponds to half production or shutdown plan (such as night maintenance), with energy saving as the main goal. Cleanliness threshold adjustment, according to ISO 14644-1 standard (i.e., international standard for clean rooms and related control environments), the cleanliness level is dynamically set, a stricter cleanliness threshold is used in high capacity period, and a relaxed cleanliness threshold is used in low capacity period (such as Class 5 in high capacity period, Class 7 in low capacity period), if the real-time cleanliness data is lower than the threshold, trigger an early warning and adjust the strategy. Energy consumption constraint setting, the energy consumption peak value in high capacity period is allowed not to exceed the maximum power consumption under the same historical working conditions (such as full speed operation of the fan), and the energy consumption limit is set to 75% of the historical average power consumption in the low capacity period (such as shutting down 50% of non-critical fans). Production priority strategy: Prioritize the operation of key fans FFU (such as around production equipment) during operating hours to ensure that cleanliness meets standards; shut down equipment in non-production areas during non-operating hours and reduce the fresh air volume to the minimum level to maintain basic cleanliness (such as maintaining only 30% fresh air volume).
[0022] As described in step S3 above, based on the real-time data of S1, the dynamic control strategy of S2 and the historical energy consumption data, the control instructions are calculated through the deep learning model and the equipment is driven to execute. Among them, the historical energy consumption data refers to the historical operation power consumption records of the equipment and scenes in the clean room, including the energy consumption data of the fan FFU in different time periods in the past (such as high capacity, low capacity), AC FFU at different operating frequencies, gears and DC FFU at different voltages and speeds, production scheduling-related energy consumption (overall equipment power consumption under historical production plans (such as full production, half production, and shutdown)) and environmental control energy consumption (records of additional energy consumption required to maintain specific temperature, humidity and cleanliness levels). The deep learning model structure includes an LSTM network module, which uses historical environmental parameters (temperature, humidity, cleanliness), equipment operation data (fan frequency, valve opening), and production scheduling as input to predict the energy consumption demand and cleanliness change trend in the next 1-4 hours. The reinforcement learning module uses real-time environmental parameters, equipment power consumption, and production scheduling status as the state space, fan filter unit opening adjustment value (0-100%), fan start and stop instructions (number + frequency) as the action space, and cleanliness standard reward + energy consumption penalty (if it exceeds the constraint threshold) as the reward function. The control instructions are generated through the model output results: fresh air volume adjustment, calculate the minimum fresh air volume that meets the predicted cleanliness requirements, and convert it into the valve opening percentage (for example, if the prediction needs to increase the cleanliness to Class 5, the opening increases from 40% to 60%); fan start and stop strategy, according to the operation period and energy consumption constraints, determine the fan number and operating frequency to be started (for example, start fan A / B during high-capacity period, frequency 50Hz); physical equipment drive, the fan filter unit (FFU) controller receives the gear and frequency instructions, adjusts the gear and frequency of each fan FFU; receives voltage and speed parameters, and controls the operation status of the DC FFU equipment. Collect actual cleanliness data, power consumption, and equipment status after adjustment; if the actual energy consumption exceeds the predicted threshold or the cleanliness does not meet the standard, trigger model parameter optimization (such as adjusting LSTM weights or reinforcement learning reward functions); adapt to environmental changes through online fine-tuning (such as daily incremental training).
[0023] The deep learning model is a multi-objective optimization model. The LSTM module uses mean square error and cross entropy loss to optimize the prediction accuracy. The reinforcement learning module iteratively optimizes the control strategy in a simulation environment through the Q-learning algorithm and adapts to the feature differences of different clean room scenarios through transfer learning.
[0024] Example 1: Company A's equipment configuration includes 6 EC fans with a total power of 55KW. The operation mode is traditional fixed rule control, and the fans run at full speed all day. The problem is high energy consumption and large fluctuations in cleanliness.
[0025] In this embodiment, by deploying temperature and humidity sensors, cleanliness monitors, dust particle collectors and smart meters, environmental parameters and equipment power consumption data are collected in real time; the data is transmitted to the edge computing device through the Modbus protocol. According to the production schedule, high-capacity periods (8:00-20:00) and low-capacity periods (20:00-8:00) are divided; during high-capacity periods: the cleanliness threshold is set to Class 5, and the energy consumption constraint is 95% of the historical maximum power consumption; during low-capacity periods: the cleanliness threshold is relaxed to Class 7, and the energy consumption limit is 65% of the historical average. Through AI dynamic control and execution, the LSTM network module predicts the cleanliness trend and energy consumption demand in the next 4 hours, and the reinforcement learning module generates fan start and stop instructions and fresh air humidity adjustment values; all 6 fans are started during the high-capacity period, and the fresh air valve opening is 80%, and 3 non-critical fans are turned off during the low-capacity period, and the fresh air valve opening is reduced to 30%.
[0026] The comprehensive energy saving rate is 35%; the cleanliness compliance rate is 98% during high-capacity periods and 100% during low-capacity periods.
[0027] Example 2: Company B has 32 EC fans, 37-75KW, and 18 fresh air FFU fans, 11-30KW. The operation mode is manual intervention control, and the energy consumption fluctuates greatly. The problem to be solved is the large number of equipment, high control complexity, and great energy saving potential.
[0028] This embodiment deploys multiple sets of sensors and smart meters to monitor environmental parameters and equipment power consumption in real time, and transmits data to the cloud database through the MQTT protocol. According to the production schedule, the high-capacity period (7:00-19:00) and the low-capacity period (19:00-7:00) are divided; the cleanliness threshold of the high-capacity period is set to Class 5, and the energy consumption constraint is 90% of the historical maximum power consumption; the cleanliness threshold of the low-capacity period is relaxed to Class 8, and the energy consumption limit is 60% of the historical average. The cleanliness trend and energy consumption demand for the next 6 hours are predicted through a deep learning model, and the fan start and stop instructions and fresh air humidity adjustment values are generated at the same time. All 32 fans (frequency 45Hz) are started during the high-capacity period, and the fresh air valve opening is 85%; 20 non-critical fans are turned off during the low-capacity period, and the fresh air valve opening is reduced to 25%.
[0029] The comprehensive energy saving rate is 38%, the cleanliness compliance rate is 97% during high-capacity periods and 100% during low-capacity periods.
[0030] Example 3: Company C has 6 EC fans with a total power of 22KW. The operation mode is fixed rule control, and the fans run at full speed all day. The needs of high energy consumption, low control accuracy and energy saving need to be solved. By deploying temperature and humidity sensors, cleanliness monitors, dust particle collectors and smart meters, environmental parameters and equipment power consumption data are collected in real time; data is transmitted to edge computing devices through the Modbus protocol. According to the production schedule, high-capacity periods (9:00-21:00) and low-capacity periods (21:00-9:00) are divided. The cleanliness threshold of the high-capacity period is set to Class 5, and the energy consumption constraint is 90% of the historical maximum power consumption; the cleanliness threshold of the low-capacity period is relaxed to Class 7, and the energy consumption limit is 60% of the historical average. Predict the cleanliness trend and energy consumption demand in the next 4 hours and generate fan start and stop instructions and fresh air humidity adjustment values. All 6 fans (frequency 40Hz) are started during the high-capacity period, and the fresh air valve opening is 75%; 3 non-critical fans are turned off during the low-capacity period, and the fresh air valve opening is reduced to 20%.
[0031] The comprehensive energy saving rate is 40%, and the cleanliness compliance rate is 99% during high-capacity periods and 100% during low-capacity periods.
[0032] Through the above examples, this technical solution demonstrates significant energy-saving effects (comprehensive energy-saving rate of 35%-40%) and improved cleanliness compliance rate (97%-100%). The present invention is applicable to clean room scenarios of different scales and configurations, and has wide applicability and economic value.
