Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related toWhen attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodimentDescribed in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appendedThe example of device and method being described in detail in claims, some aspects of the invention are consistent.
Embodiment 1
Cooler compressor electric heating controlling method provided by the invention is illustrated with reference to the accompanying drawing.
Cooler compressor electric heating controlling method provided by the invention can be applied on domestic air conditioner, can be in quotientIt is realized in the commercial use air conditioners such as field or marine air conditioner equipment.Fig. 1 shows a kind of optional flow chart of this method, such as Fig. 1 instituteShow, which may comprise steps of:
S102, monitoring know that the cooler compressor time out of service is more than the first preset time threshold, send first and askAsk information to database server, to obtain the weather forecast number of air conditioner region in following second preset time thresholdAccording to；
Specifically, for example, when cooler compressor dwell time T >=1h is known in monitoring, the first solicited message is sentTo database server.Preferably, air conditioner region is positioned to determine air conditioner by the communication module of air conditioner built-inLocation information；Obtain preset second preset time threshold；Generation include air conditioner location information and second it is default whenBetween threshold value the first solicited message, and be sent to database server to obtain air conditioner institute in following second preset time thresholdData of weather forecast in region, wherein database server parses the first solicited message, accesses day by own network interfaceGas platform obtains the corresponding data of weather forecast of the first solicited message, and is back to the communication module of air conditioner.
S104, receives the data of weather forecast that database server returns, and generates control strategy according to data of weather forecastTo control the electrically heated start and stop of cooler compressor.
When specific implementation, in the data of weather forecast that database server returns, third after current time is filtered outData of weather forecast in preset time threshold；Analyze temperature value in the data of weather forecast determined in third preset time thresholdTrend is changed over time, is that control cooler compressor opens electric heating in the time increased in variation tendency, in variation tendencyElectric heating is closed to control cooler compressor in the non-time increased.
In of the invention one optional embodiment, a kind of simply and effectively analyze when determining that third is default is providedBetween in data of weather forecast in threshold value temperature value change over time the scheme of trend, specifically, by third preset time thresholdValue is divided into preset n unit interval, is denoted as F respectively1…Fk…Fn, wherein n, k are natural number, k ∈ [2, n]；Calculate nA unit interval F1…Fk…FnIn in each period temperature average value, be denoted as t respectively1…tk…tn；Compare per a period of timeBetween in section in the average value of temperature and the previous time period of the period temperature average value, determine in third preset time thresholdData of weather forecast in temperature value change over time trend.
When carrying out above-mentioned compare, it can be realized using following scheme, be calculated by the following formula and judge:
Work as tk-t(k-1)When > 0, determine in FkIt is the time increased that temperature value, which changes over time trend, in period；Work as tk-t(k-1)When≤0, F is determinedkIt is the non-time increased that temperature value, which changes over time trend, in period.
In addition, characterizing data of weather forecast in third preset time threshold as k=n and being disposed, continue transmission firstSolicited message is to database server, to obtain the weather forecast number of air conditioner region in following second preset time thresholdAccording to circulation carries out according to this.
2 pairs of cooler compressor electric heating controlling methods of the invention are further detailed with reference to the accompanying drawing, withJust the present invention is better understood.
Cooler compressor dwell time T >=1h is known in S201, monitoring, triggers step S202；
S202, communication module obtain its location information by cellular network location self-position；And communication module rootThe request for using data of weather forecast is sent according to demand；
Two information in S202 are sent to specified server (database clothes by cellular network by S203, communication moduleBusiness device)；
S204, the information that server receives communication module transmission obtain the local following weather forecast number by internet channelAccording to；
S205, server send the data of weather forecast of acquisition in communication module；
S206, communication module return to the information received into the controller of air conditioner；
S207, controller start T0 backward at the time of interception corresponding to compressor dwell time T according to data of weather forecastAll data of the weather forecast that=6h is included；
The data (data in the following T0) of interception are divided into n points, define every equal part and be recorded as F1 ... Fk ... by S208Fn.Every part of data processing is obtained into its average value, i.e., the average of every equal part are as follows: t1 ... tk ... tn；It defines k to take [2, n], n is extremelyIt is less 2；
S209 judges to detect tk-t (k-1) > 0, if so, executing step S210, otherwise, executes step S211；
S210, reservation electric heating unlatching at the time of waiting subregions Fk to correspond to；
S211, reservation electric heating closing at the time of waiting subregions Fk to correspond to；
S212 judges whether k=n, if so, the S202 that gos to step, otherwise, go to step S209.
It can be seen that from the above description, in the present invention, portion is provided with the communication mould for network communication in the air conditionerBlock, can with the database server connection communication comprising weather data, also, the default compressor of air conditioner time out of service whenBetween threshold value.When the cooler compressor time out of service being more than the first preset time threshold, pass through the communication module and dataLibrary server establishes connection, and transmission includes solicited message to the database server, and having time request is carried in solicited messageThe position request information of information and air-conditioning region is establishing connection with data server and is receiving the required weather of returnAfter forecast data, using the data of weather forecast as air conditioner be in the standby state compressor whether need it is electrically heated according toAccording to.This control program, which efficiently solves air conditioner in the prior art and is in the standby state compressor, still needs to a large amount of electric heatingThe problem for causing compressor of air conditioner stand-by power consumption big reduces the electric heating opening time under air-conditioner standby state, decreases energy consumption.
