Specifically, as shown in fig. 1, the intelligent regulation and control system of the present invention includes: the system comprises a machine room control device 1 and an analysis device 2, wherein the machine room control device 1 is further detailed into an environment detection module 1-1, a temperature regulation module 1-2, a sub-strategy analysis module 1-3 and a temperature control temporary instruction module 1-4;
the environment monitoring module 1-1 is configured to uniformly manage all machine room environment information of the machine room, such as temperature, humidity and monitoring devices (for monitoring energy consumption, load, and the like), and share the machine room environment information in real time (or at a certain period) to the sub-policy analysis module 1-3 and the temperature control temporary instruction module 1-4. And the environmental information of the machine room between the last temperature control strategy update and the current temperature control strategy update is stored and processed to generate an environmental information log.
The environment monitoring module 1-1 may specifically include an infrared temperature measuring device, a humidity detecting device, and a network connection device to obtain local environmental information such as air temperature and air speed (for recording local climate environment differences and adjusting the temperature of the machine room according to the climate differences). The devices are arranged beside the servers in the machine room and are arranged according to the division of the machine room server groups. The devices are directly connected with a processor of the environment monitoring module 1-1 through a data line or through a wireless network signal connection, and are used for transmitting monitoring data in real time.
The temperature adjusting module 1-2 is used for controlling all temperature control equipment of the machine room in real time, cooling the equipment before a load peak comes, and controlling the temperature based on the instructions sent by the sub-strategy analysis module 1-3 and the temperature control temporary instruction module 1-4.
The temperature adjusting module 1-2 specifically comprises a cooler (an air conditioner and the like), a cooling water pump is uniformly installed indoors according to requirements, and is directly connected with a processor of the temperature adjusting module 1-2 through a data line or a wireless network. Every computer lab temperature control equipment all has 3 ~ 8 control by temperature change gears for realize the temperature control (cooling) intensity of different degrees.
The temperature adjusting module 1-2 usually performs a temperature reduction operation in advance on a predicted load peak according to a current temperature control strategy and machine room environment information, and if the temperature of a few servers in the machine room exceeds a temperature threshold value for several times within a certain period of time, the temperature adjusting module 1-2 may perform a temporary temperature reduction by temporarily increasing the operation of a cooling water pump or reducing the temperature of a cooler. However, if the cooling power consumption temporarily increases due to an increase in the operation of the cooling water pump or a decrease in the temperature of the cooling machine, and the PUE (total power consumption/energy consumption for IT) in the machine room fluctuates several times (exceeds the PUE threshold), the environmental information log is transmitted to the analysis device 2 for analysis.
And the sub-strategy analysis module 1-3 is a module for specifically bearing a load peak prediction task of the machine room. And can be primarily analyzed and adjusted when the temperature of the machine room is not adjusted conveniently. If the optimum level is not reached, it reports the existing strategy and allows the analysis device 2 to perform an in-depth analysis process.
The sub-policy analysis module 1-3 may specifically include a computing device with a relatively high performance, and the computing device is connected to the main processor of the machine room control apparatus 1 through a data line or a wireless network.
And the temperature control temporary instruction module 1-4 is used for sending a temperature control temporary instruction to the temperature adjusting module 1-2 or sending a strategy optimizing instruction to the sub-strategy analysis module 1-3 when the conditions are met.
The working process of the intelligent regulation and control system is that the machine room control device 1 monitors and records the environmental information of the machine room in real time through the environmental monitoring module 1-1; when the environmental temperature reaches a temperature threshold, the energy consumption of the machine room or the PUE of the machine room is abnormal (exceeds the threshold or other set values, such as the maximum value of the energy consumption of the machine room or the PUE of the machine room when the previous temperature control strategy works), or after strategy information is updated, the sub-strategy analysis module is called (a strategy optimization instruction is sent or the temperature control strategy is updated and other modules are called to work under the current temperature control strategy).
The analysis device 2 may be a server with strong computing capability, large memory space and good network bandwidth, software for analyzing the temperature control strategy is deployed on the server, and after receiving the environmental information log and the strategy optimization instruction uploaded by the machine room control device 1 and other relevant information of the machine room, the current temperature control strategy is analyzed by using a machine learning algorithm to obtain an optimized temperature control strategy, so that the machine room control device 1 performs temperature regulation and control based on the optimized temperature control strategy again.
The temperature control strategy is added manually (at the beginning or at any other stage) by an operator or automatically by a system, if the PUE of the machine room exceeds the past (exceeds the PUE threshold value or the maximum value of the PUE of the machine room when the previous temperature control strategy works), the energy consumption of the machine room is larger than that before the unmodified temperature control strategy (exceeds the energy consumption threshold value or the maximum value of the energy consumption of the machine room when the previous temperature control strategy works) or the temperature of the machine room exceeds the threshold value for a plurality of times in a certain time period, the temperature adjusting module 1-2 starts to call the sub-strategy analyzing module 1-3, the sub-strategy analyzing module 1-3 starts to enter an analyzing mode, and the specific action is to request the environment detecting module 1-1 for the environment information of the machine room around a server more frequently and perform temporary temperature adjustment.
If after the temporary adjustment, it is still detected for many times or once that the PUE of the machine room exceeds the threshold value or the average energy consumption of the machine room is higher than past within a period of time, the machine room control device 1 sends the environmental information log and other information obtained from the environmental monitoring module 1-1 to the analysis device 2. And after receiving the data, the analysis device 2 optimizes or corrects the current temperature control strategy, returns the optimized temperature control strategy to the machine room control device 1, and repeats the process until the energy consumption of the machine room returns to the point before the temperature control strategy is modified or is better than the prior art.
The temperature control strategy is a control protocol for managing the temperature of the machine room, and the temperature control strategy can be composed of a plurality of instructions, wherein the instructions can be composed of 4 tuples:
for example, < 'location _ id', 'average _ temperature', 'average _ load', 'action' >, the element location _ id represents an identifier that uniquely identifies a certain machine room, the average _ temperature represents the average temperature of the machine room reached, the average _ load represents the average load of the machine room, and the action represents the operation performed on the temperature adjustment module 1-2 when the average temperature of the machine room and the average load of the machine room reach corresponding values. The temperature control strategy is used for predicting the load peak of the machine room which is possibly reached in the future in advance and cooling in time.
And the information sent to the analysis means 2 may be constituted by the following elements:
for example, machine information in the environmental information log: < 'device _ position', 'log _ time', 'load', 'temperature', where 'device _ position' represents the location of the machine room where the machine is located, 'log _ time' represents the time of information recording, 'load' represents the load, 'temperature' represents the temperature of the machine at the time of recording.
The machine refers to energy consumption equipment such as a server and machine room temperature control equipment which work in a machine room.
And other information, including the machine room information: "location _ id '," local _ weather', "local _ hub '," server _ intensity', "temperature _ control _ intensity '," city', "availability _ info '," location _ id to uniquely identify a room, "server _ intensity' to represent room server density," "temperature _ control _ intensity 'to represent average density of room temperature control devices (number of room temperature control devices/number of servers)," city' to represent city of the room, "" availability 'to represent altitude information, "" wind _ info' to represent local weather information such as local wind speed, etc.

Specifically, the temperature of the machine room in the first embodiment may be subdivided into temperature information of a single server, average temperature information in the machine room area, or average temperature information of the whole machine room according to actual needs (i.e., the machine room area is set as the whole machine room).
The energy consumption of the machine room can be subdivided into energy consumption information of a single server, average energy consumption information in a machine room area, energy consumption information of temperature control equipment of the machine room and average energy consumption (total energy consumption/energy consumption equipment number) of the machine room according to actual needs.
The machine room PUE can be calculated according to a formula, and corresponding values are substituted.
The environmental information of the machine room is transmitted in real time or in a certain period, and the environmental information log can be regarded as a data table obtained by storing and processing the environmental information of the machine room for a period of time (between the last time of updating the temperature control strategy and the current time of updating the temperature control strategy).
The server temperature acquisition submodule is used for monitoring the temperature information of a single server;
the server load and energy consumption monitoring submodule is used for detecting the load information of a single server and calculating the energy consumption information;

the environment detection module 1-1 records information generated by each sub-module in real time, and records a generated log to be called by the temperature regulation module 1-2 and the sub-strategy analysis module 1-3.
The servers in each computer room may be divided, for example, into 8 groups of servers. When performing peak prediction, this group of servers is treated as one server. The data for this set of servers is made with the average temperature and average load of these servers.
And the energy consumption of the machine room also comprises the energy consumption of power consumption equipment such as machine room lamplight and an alarm, but the quantity of the devices is generally fixed and the energy consumption is fixed, so that the device only needs to count in advance and is added as a part of total energy consumption when average energy consumption is carried out every time, and the device can be ignored if the numerical value is small.
And the system is also provided with a local meteorological environment monitoring submodule for collecting local real-time information such as temperature, humidity, wind power, wind direction and the like. And storing specific information such as the altitude of the place where the machine room is located.
Further, the analysis device 2 comprises a learning balance combiner module, a strategy optimizer module 2-2 and a knowledge base module 2-1;
the learning balance combiner module comprises at least one learner module 2-3, is connected with the sub-strategy analysis module 1-3, the strategy optimizer module 2-2 and the knowledge base module 2-1, and is used for receiving the environmental information log and the strategy optimization instruction sent by the sub-strategy analysis module 1-3 and then inputting the environmental information log into a machine learning model in the learner module 2-3 to obtain an optimized temperature control strategy; sending the optimized temperature control strategy to a strategy optimizer module 2-2, and sending the environment information log to a knowledge base module 2-1;
the strategy optimizer module 2-2 is simultaneously connected with the sub-strategy analysis module 1-3 and the knowledge base module 2-1 and is used for receiving and processing the optimized temperature control strategy, wherein the processing comprises duplication removal processing and conflict removal processing; respectively sending the optimized temperature control strategy to the sub-strategy analysis module 1-3 to replace the current temperature control strategy, sending the optimized temperature control strategy to the knowledge base module 2-1, updating the knowledge base module 2-1, and marking the optimized temperature control strategy as the current temperature control strategy; the knowledge base module 2-1 is used for receiving all environment information logs sent by the learning balance combiner module and all temperature control strategies sent by the strategy optimizer module 2-2, storing the environment information logs and the temperature control strategies according to the corresponding relation, completing updating and sending an updating signal to the learning balance combiner module;
and the learning balance combiner module is also used for training the machine learning model in the learner module 2-3 by taking all the environmental information logs and all the temperature control strategies stored in the knowledge base module 2-1 as a training set according to the updating signal to obtain an optimized machine learning model.
Specifically, as shown in fig. 1, when the environmental information log and the policy optimization command sent by the sub-policy analysis module 1-3 are sent to the learning balance combiner module, the environmental information log is transmitted to different learner modules 2-3 to obtain at least one optimized temperature control policy, the newly learned optimized temperature control policies are combined, the combined optimized temperature control policies are transmitted to the policy optimizer module 2-2 to perform operations such as deduplication and conflict elimination, and finally the optimized temperature control policy is returned to the knowledge base module 2-1 to update the knowledge base module 2-1, and the optimized temperature control policy is returned to the machine room control device 1 to replace the current temperature control policy.
The knowledge base module 2-1 fully utilizes the difference data generated by each machine room to integrate. And the knowledge base module 2-1 is dynamically updated in real time because the strategy is continuously optimized. The learner modules 2-3 adopt different machine learning methods and apply machine learning algorithms to optimize strategies which possibly have problems, and energy wasted by a machine room is reduced as much as possible. After the temperature control strategy is updated, the learning balance combiner module takes out the environmental information logs collected from all the machine rooms and the corresponding temperature control strategies from the knowledge base module 2-1, and trains the machine learning model in each learner module 2-3 by calling the learner module 2-3.
The training process of the middle machine learning model of the learner module 2-3 is as follows: when the analyzer 2 receives the analysis request from the room control apparatus 1, the analyzer 2 first normalizes the environment log information into a pattern (pattern) having a format similar to a rule in a policy but lacking an action field. And then, the analysis end starts to call different learner modules 2-3, and inputs the converted environmental information log and the temperature control strategy into the learner modules.
The training process for the three classes of learner modules 2-3 is briefly set forth below:
1. neighbor learning device
The policies in the schema collection and the knowledge base are mapped into the same high-dimensional space. For each mode, several (set threshold) instructions similar to it are fetched (each rule in the policy is called an instruction). These similar vectors are voted and the final mode is marked as the most numerous actions.
2. Pattern rule distance learning device
And (4) establishing a tree for the strategies in the knowledge base, wherein each layer corresponds to one field in the strategy. And for each mode, comparing layer by layer according to the fields. When a field is matched and the matching depth exceeds a threshold value, the field cannot be matched. And counting decision fields of all subtrees under the field. Labeling is done in most cases.
3. Commonly-appearing learning device
Within a certain time period, certain two patterns occur in succession, referred to as co-occurrence.
The co-occurrence probability is represented by cij, and the calculation formula is as follows: number of co-occurrences of Pattern i and Pattern j/Total number of occurrences of Pattern i
The probability of the common occurrence of all n different access patterns occurring in the log can be represented by an n x n matrix
After the learner computes the matrix, the learner ranks the rows that first represent the new pattern from large to small. Thereafter, truncation is performed according to a threshold and voting is performed according to patterns known to occur in the strategy. The final majority of actions are the final actions of the current mode.
The strategy optimizer module 2-2 receives the updated strategy of the combination sent by the learning balance combiner module, optimizes the strategy (including the operation of removing the duplicate and conflict), and finally updates the knowledge base module 2-1 and returns the updated knowledge base module to the machine room control device 1.
