The mobile terminal can provide the user with the name of the electric appliance which is set manually, so that the user can conveniently manage the electric appliance, and the current reference standby and working power loss parameter values can be obtained from the server terminal and displayed to the user.
Referring to fig. 3, fig. 3 is a flowchart illustrating an initial detection of an operating state of an electrical device of an intelligent control system based on an intelligent socket according to an embodiment of the present application. The working state initial detection flow chart of the electrical equipment of the intelligent control system based on the intelligent socket mainly judges the working state by sampling the real-time power value, so that a relative standby power reference value is converted and sent to the server for storage. The electrical equipment working state initial detection of the intelligent control system based on the intelligent socket specifically comprises the following steps:
after the intelligent socket module is plugged in an electric appliance, the electric quantity detection module connected to the socket starts electric quantity detection for 1s and samples, a sequence is formed, and three continuous sample points { P ] of anti-shake processing are listed in fig. 2m ,Pm+1 ,Pm+2When the condition P is satisfiedm 、Pm+1、Pm+2 >Triggering state detection to start at 0;
in the embodiment of the invention, the specific values of the working power and the stable output fluctuation range of different electrical equipment are not concerned, and the fluctuation range of the standby stable operation is more concerned. When three consecutive sample points satisfy the following relation:
Δ|Pmm+1| < P b ①
| Pmm+2 - Pm| < P b ②
in the above relation, PbFor the fluctuation factor parameter, Pmm +2 is the mean of three consecutive samples
When the relational expressions (i) and (ii) are satisfied simultaneously, the electrical appliance on the socket may be in a standby state or in a working state with a high probabilityA state; when not satisfied, the electrical equipment may be in an operation critical state (a rising edge ready to start operation or a falling edge standby or off state), and thus may be used for the preliminary operation state reference power value PwAnd (4) obtaining.
When the stable standby working condition is met, the judgment of P is carried out in four modessiParameter (wherein Ps0Corresponding to a standby state, a minimum standby power; ps1Corresponding to a state operating in standby): the four states are respectively according to Ps0、Pw、Ps1Comparing the corresponding parameter value with the sampling mean value to obtain the minimum reference standby power Ps0And Ps1In which P iss1Not all electrical devices are necessarily present, and are acquired only as the state determination value.
When the steady standby operating condition is not met and the continuous sampling power is greater than 0, the device may be in a large fluctuation state: the rising edge starts working, the falling edge turns to standby or the falling edge turns to off state. The determination conditions are respectively determined according to whether the reference working power is set: if not, then P ismSequence value is incremented and rising edge maximum value Pm+2Greater than Ps0Then, the working power P is referencedwIs Pm+2(ii) a When P is presentmSequence value is incremented and rising edge maximum value Pm+2Less than Ps0When it is, then PwValue is set to Ps0While the reference standby power P is explaineds0If the acquisition is not accurate, the power is required to be updated and reset to 0 immediately to wait for the acquisition of the stable standby power; if P is setwThen P is required to be adjusted according to the maximum power value pairwThe update is done to ensure that the operating power is greater than the standby power, a basic requirement.
After the state value is determined, the smart jack module needs to send the reference standby power data to the server for storage. The basic parameter validity conditions are listed in FIG. 3, only if Ps0Not equal to 0 and PwDetection is considered valid only if not equal to 0.
The state detection process described in this embodiment is directed to the state determination without initial data, and the state with reference dataThe values may also change in accordance with the operating parameters as the appliance is replaced. Therefore, for this situation, it is only necessary to buffer the previous reference power data and automatically reset P when the power value of the corresponding electrical appliance on the smart jack is detected to be 0 when the smart jack is turned off or turned on according to the above-mentioned flowchart descriptions0、Ps1、PwThe parameter values. And (4) continuing self data sampling detection according to the illustrated flow, and when the new standby reference power value is changed, sending the changed parameter value to a server for storage processing.
Referring to fig. 4, fig. 4 is a flowchart illustrating a process of preprocessing data reported by an intelligent socket module of an intelligent control system based on an intelligent socket according to an embodiment of the present application. Fig. 4 shows the turn-on time of the electrical device during operation, which is listed on a certain day, and respectively shown in 8: 00-9: 00 and 19: 10-22: 20 are opened.
The sampling time interval of the real-time power reported by the intelligent socket is 30 minutes, so that the server receives a sequence { P with the length of 48 in one day0,P1, ......, P47It should be understood that, in the embodiment of the present application, other times may also be used as the sampling time interval;
the server performs state conversion processing on each sample point, and defines P asn <= (Ps + Pb) When the sample is in a standby state, the recorded value of the sample is '0', and the sample is represented to work in a standby state or no load state; otherwise, the record value is '1', which represents the working state, and thus can be converted into a binary data sequence {0, 0. According to the working conditions shown in FIG. 4, the serialized data would be "0000000000000000000111111000000000000000000000110000000000000000", converted to hexadecimal 0x00001F8000030000, and saved in a database table with the current working date.
For data uploaded by the intelligent socket module, the abnormal situation that the intelligent socket module is connected with the server needs to be considered, and the processing aiming at the abnormal situation is as follows: when the intelligent socket module is disconnected from the server due to external reasons, the acquired data needs to be cached in local Flash for storage so that the server can accurately record the data; and after the intelligent socket module is restored to be connected with the server, sending the cache data to the server, and emptying the local cache to release the storage space after the cache data is successfully connected with the server.
The interpolation of the sample point of the intelligent socket module in the off state and the power-off state (the intelligent socket has no data cache) is recorded as '0'.
Referring to fig. 5, fig. 5 is a flowchart illustrating a process of predicting and recommending stored data by a server of an intelligent control system based on a smart socket according to an embodiment of the present application. The server of the intelligent control system based on the intelligent socket specifically performs prediction processing and recommendation on the stored data, and includes:
the server preprocesses the data, and according to the preprocessing result data, the server stores a period sequence { { d ] corresponding to a parameter table every dayt0 ,W0}, {dt1 ,W1}, ......, {dtn,Wn}}；
After receiving the standby reference power and the working power value, the server needs to process the data. In the control system, a main purpose is to extract a working state period distribution rule value meeting the system requirement, so that the working distribution value in the future time can be accurately predicted. In the server data processing, because the work of the intelligent device follows the living habits of the user, the intelligent device has obvious periodicity and holiday rules, the minimum time granularity of 30 minutes is used as statistics in the embodiment of the invention, and it can be understood that other times can also be used as the minimum time granularity. The general periodic prediction model adopts autoregressive average prediction or autoregressive and moving average prediction, the prediction methods need to combine with the actual demand environment to make selection and corresponding data preprocessing, the selection of the model depends on more data preprocessing modes, and the invention adopts an exponential weighted average prediction model after preprocessing the data according to the demand of system design.
In the embodiment of the invention, the basic scheme of data preprocessing is as follows: the actual working state of the electrical equipment needs to be determined, and the specific working energy consumption value in the current state is not concerned. Therefore, certain conversion is made to the working state: when the standby state is defined, the value is 0; in the operating state, the value is 1. The data statistics and prediction period is in week units, the minimum statistical data record is stored according to the day, the record value conversion according to half an hour is that the data in each day is 48 values, and the data is correspondingly converted into binary data (the lower bit corresponds to 12 points at night, and the upper bit has no data value of 0), so that the consumption of a large amount of data storage and operation is reduced, the server requires a 64-bit CPU and an arithmetic logic unit architecture, and the server can adopt other architectures and CPUs. Assuming monday of a week, the device on-time is 18: 30-21: 30, at this time, the data of the current day will be "0000000000000000000000111110000000000000000000000000000000000000" after being converted. Similarly, if monday of a week, the device turn-on time is 7: 30-9: 00, 19 pm: 00-22: 00, the data will be "0000000000000000000011111100000000000000000000111000000000000000" after conversion.
The discrete data sequence generates different data values along with the increase of time or the change of seasons, the change of the data has certain regularity all the time and has strong correlation degree with the time, so the prediction by adopting an exponential weighted average method is more accordant with the actual environment of a user, and a more accurate schedule for turning on the electric appliance every week in the future is formed.
In the embodiment of the invention, the storage time of the statistical data records of the server is defined as one year, and the accuracy of the predicted data is slightly influenced by the low relevance of the data of more than one year; the minimum period for server data record saving is defined as two weeks, and data below two weeks will only be saved and preprocessed and not used for prediction.
Server prediction result processing, wherein the intelligent system design is concerned, so that the prediction result automatically pushes corresponding prediction timing information to a mobile application program user using an intelligent socket by the server; the user can view the recommended timing task list and adopt the recommended timing task by one-key permission. The later working mode of the intelligent socket does not need additional manual control, and whether the power supply is forgotten to be turned off or not is considered.
And (3) fault-tolerant processing of the prediction result of the server, wherein when the prediction result is inconsistent with the actual use of the user, the server needs to execute an automatic identification turn-off timing task, take the operation behavior of the user as a main control party on the basis of not influencing the use control of the user, and simultaneously perform friendly message processing to remind the user of the working task state of the current household equipment.
After the server acquires the information of the intelligent socket, automatic preliminary preprocessing is required to be carried out, and the state of the socket is judged to be four states: off state (W)0) No load state (W)1) Standby state (W)2) And an operating state (W)3) Here standby state (W)2) The main points are that the power supply is not on when the electric appliance is plugged; the working state (W3) comprises a normal working state and a state of not working for a period of time and being in a dormant state, such as a standby state of a television set-top box. Wherein, the closed state W0The intelligent socket actively sends the information to the server; no load state W1Determining according to the actual idle power value (0 watt) of the intelligent socket; standby state W2And operating state W3The judgment is carried out by taking the rising edge time or the falling edge time as a sampling point, the sampling time interval of the electric quantity detection module inside the intelligent socket is 1 second, and it can be understood that the sampling time interval of the electric quantity detection module inside the intelligent socket can also be set to other times. Assuming that the socket is in the open to closed state, the power sequence for obtaining the sample is { P }0,P1,P2,P3,...,PnAnd ensuring data acquisition of interpolation sampling points in order to avoid the occurrence of sampling points on rising edges or falling edges, namely
ΔPn = (Pn - Pn-1), (n ≥ 2)
Will correspond to | Δ PnThe | value is stored in the Pn corresponding table of the server-side database at the same time, and for n<The value at 1 is taken to be 0 and the parameter is ignored. According to the principle that the fluctuation range of the standby power is smaller than the reference Pb value, generally 0.3W, | delta P is obtained when the intelligent socket is powered on for the first time or is started for the first time1The value of is greater than 0 and P0When 0 is equal to the above-mentioned value, its working stateIs judged as W2Recorded simultaneously as the standby power reference value Ps0And reporting to a server for storage; when | Δ P1When the value of | is always equal to 0, recording the working state as W1At this time, the standby power reference value is not recorded yet, and the continuous sample point detection waits for the mth | Δ PmStandby power reference value P with | value greater than 0s0At this time, it is possible to directly raise the electric appliance to the working state W within the sampling interval3(for example, a mobile phone charger and a mobile phone are connected in the closed state of the smart socket, and the smart socket is opened at the moment, so that the instantaneous power is the working state power). Therefore, the standby power at this time is only a reference value, and | Δ P corresponding to a certain sampling point m after the time shiftm+1The range of | fluctuation is larger than PbJudging the rising edge or the falling edge of the signal, and when the rising edge is the rising edge, Ps0The initial value can correspond to the initial standby state judgment (the power is connected with the equipment, and the equipment is not started up); when the sampling point is a falling edge, the average value and the | delta P of three continuous sampling points are ensured because the power consumption value of part of equipment in the working state is not fixedmI meets the standby condition and records the standby Ps1The last time Ps is the working power PwA reference value. Sequentially and periodically sampling in real time and converting the corresponding Ps0、Ps1、PwThe reference is pushed to the server.
After the last working state reference power value is obtained, two situations may exist in the subsequent electric equipment working: a user always uses the same electrical equipment to work; the user irregularly changes the electrical equipment on the intelligent socket. Therefore, the state reference value is not always fixed, and for the first case, the smart jack module only needs to perform a simple reference standby power comparison without sending a reference power value update to the server again; for the second case, after the electrical equipment working on the smart socket at a certain stage is replaced, the electrical performance index of the electrical equipment will change. And the server stores and processes the working state of the intelligent socket according to the standby reference power value each time.
In the embodiment of the invention, the working state of the intelligent socket and the reference standby power and working power value are defined, which actually refers to the working state of the electrical equipment on the intelligent socket, and the intelligent socket of the electrical equipment cannot judge which electrical equipment is used. As a part of system control, in the application program of the mobile terminal, the name of the electric appliance can be set manually by a user for facilitating user management, and meanwhile, the current reference standby and working power loss parameter values can be obtained from the server side and displayed to the user side.
The server regularly acquires an API (application program interface) of annual festivals and holidays and records the festivals and holidays; the server separates the stored data according to the holidays, thereby forming two data sequences of the holidays and the weekdays;
establishing a multidimensional entropy prediction model Vij= β*Vij-1 + (1-β)*（（Wi/2j) % 2), (j = 0,1,. 47), wherein T ≈ 1/(1- β); t corresponds to a period value; v0j = 0，VijThen the corresponding prediction parameter value is obtained;
for the prediction parameter with the maximum redundancy, a reference judgment value V is takenb(the value of this value is set depending on the actual scene requirement test) only if Vij < VbWhen the value is '0'; otherwise, the value is '1'.
The server derives the prediction sequence data of one week according to the flow, converts the prediction sequence data into a work task data table of one week according to the sequence prediction data, and simultaneously pushes a message to the mobile user application program; the mobile application program can check the recommended timing task message pushed by the server; when the user authorizes the work adopting the work task table, the server pushes the timing task table to the intelligent socket.
Because the life rule has obvious periodicity, the required statistical data does not need a very long period, the invention only needs to meet the statistical data requirements of maximum one year and minimum two weeks, and the time correlation degree of more than one year is small and can be almost ignored.
The invention adopts an intelligent recommending and authorizing mode, which does not need to destroy the original use habit of the user and force the user to execute according to the intelligent mode, and only needs one-key authorization to use the user with the requirement.
In the intelligent control method based on the intelligent socket, the application program of the mobile terminal comprises the alias of the self-defined intelligent socket, the push message (comprising information such as intelligent recommendation, abnormal power alarm and user management) of the server, the control interaction with the server, the intelligent recommendation of the authorized user and the recommendation task information checking.
The implementation process of the embodiment of the invention is described and completed, the actual use environment is fully considered in the whole embodiment, the establishment of the sequence analysis table corresponding to the environment division of the actual life law is included, and meanwhile, the intelligent operation mode of the use habit of the consumer is also included. The embodiment changes the traditional system control method for only performing electric quantity data statistics display for the user, and adopts the system control method intelligently set for the user. In the whole embodiment, the implementation mode of the system is different from that of the traditional method: firstly, the states of the intelligent sockets are clearly divided, and the standby state with high attention is treated as special treatment; secondly, on the basis of the adopted prediction model method, the data is subjected to own data preprocessing according to the actual operation scene, so that the resource occupation of a large amount of data statistics on the server is greatly reduced, and the operation efficiency in the implementation process is correspondingly improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
