Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Refer to an embodiment of the air-conditioning Bluetooth remote control control method of the present invention shown in Fig. 1 and Fig. 2, wherein, Fig. 1 is the main flow chart of this embodiment, and Fig. 2 is a flow chart of refrigeration mode.
As shown in Figure 1, the main flow that this embodiment realizes air-conditioning Bluetooth remote control control method comprises the steps:
Step 101: air-conditioning receives Bluetooth control signal, judges Bluetooth control signal type.
By arranging Bluetooth signal receiving circuit on air-conditioner host control panel, the Bluetooth control signal that blue Tooth remote controller sends can be received.And Bluetooth control signal or be close machine control signal, or is a key control signal.After Bluetooth signal receiving circuit receives Bluetooth control signal, according to the decoding corresponding with remote controller rule, signal is decoded, just can judge that Bluetooth control signal is a key control signal or closes machine control signal.
Step 102: judge whether the Bluetooth control signal received is a key control signal.If so, the key control process of step 104 to step 109 is performed; Otherwise, perform step 103.
Step 103: if judge that the Bluetooth control signal received is not a key control signal, then for closing machine control signal, control air-conditioning shutdown.
Step 104: if step 102 judges that the Bluetooth control signal received is a key control signal, perform a key control process.First, obtain current indoor light intensity, and make comparisons with setting light intensity.
Indoor light intensity can be detected by the photosensitive sensor be arranged on air-conditioning and be obtained by the processor process on air-conditioner host.Setting light intensity is for judging that indoor light is strong and weak, presetting and be stored in a value in air-conditioner host processor memory cell.The default value that this value is arranged when can be and dispatch from the factory also can be that user is according to the amended value of actual conditions.
Step 105: judge whether current indoor light intensity is less than setting light intensity.If so, step 106 is performed; If not, step 108 is performed.
Step 106: if step 105 judges that current indoor light intensity is less than setting light intensity, show that indoor light is weak, then control air-conditioning and enter sleep pattern.And, need to judge it is perform refrigeration mode under sleep pattern or heating mode according to current indoor temperature.Specifically, obtain current indoor temperature, and compare with the first design temperature or the second design temperature.
Wherein, current indoor temperature can be detected by the temperature sensor be arranged on air-conditioning and be obtained by the processor process on air-conditioner host.First design temperature and the second design temperature are the values presetting and be stored in air-conditioner host processor memory cell, and the default value arranged when can be and dispatch from the factory also can be that user is according to the amended value of actual conditions.Wherein, the first design temperature is as judging whether a reference value entering refrigeration mode, and its value is greater than the second design temperature as a reference value judging whether to enter heating mode.Such as, the first design temperature is 28 DEG C, and the second design temperature is 22 DEG C.
Step 107: according to the refrigeration mode under comparative result execution sleep pattern or heating mode.
Specifically, if when current indoor temperature is greater than the first design temperature, show that indoor environment temperature is too high, then control air-conditioning and enter refrigeration mode under sleep pattern; If current indoor temperature is less than the second design temperature, represent that indoor environment temperature is too low, then control air-conditioning and enter heating mode under sleep pattern.
For the heating mode under sleep pattern, existing control procedure can be adopted realize.Such as, heating mode adopts PID to control compressor operating frequency, and after operating 1 hour under sleep pattern, setting target temperature reduces by 2 DEG C; 3 DEG C are reduced again after rerunning 1 hour; After running reaches 8 hours total time, air-conditioning will shut down.And refrigeration mode preferably adopts the control procedure described by Fig. 2, refer to subsequent descriptions.
Step 108: if step 105 judges that current indoor light intensity is not less than setting light intensity, shows that indoor light is strong, does not then perform sleep pattern.And, need to judge it is perform refrigeration mode under non-sleep pattern or heating mode according to current indoor temperature.Specifically, obtain current indoor temperature, and compare with the first design temperature or the second design temperature.
Step 109: according to the refrigeration mode under comparative result execution non-sleep pattern or heating mode.
Specifically, if when current indoor temperature is greater than the first design temperature, show that indoor environment temperature is too high, then control air-conditioning and enter refrigeration mode under non-sleep pattern; If current indoor temperature is less than the second design temperature, represent that indoor environment temperature is too low, then control air-conditioning and enter heating mode under non-sleep pattern.
For the heating mode under non-sleep pattern, existing control procedure can be adopted realize, and refrigeration mode preferably adopts the control procedure described by Fig. 2, refers to subsequent descriptions.
No matter be sleep pattern or non-sleep pattern, if current indoor temperature does not meet the condition entering heating mode or heating mode, air-conditioning can not do any action.As one preferred embodiment, can also pre-set the 3rd design temperature between the first design temperature and the second design temperature, such as, getting the 3rd design temperature is 23 DEG C.When current indoor temperature is not more than the first design temperature but is greater than the 3rd design temperature, control air-conditioning enters the refrigeration standby mode under sleep pattern or the refrigeration standby mode under non-sleep pattern.And when current indoor temperature is not more than the 3rd design temperature and is also not less than the second design temperature, control air-conditioning enters the heating standby pattern under sleep pattern or the heating standby pattern under non-sleep pattern.Under refrigeration standby mode, in advance cross valve, expansion valve opening etc. are adjusted to refrigeration mode state, and under heating standby pattern, in advance cross valve, expansion valve opening etc. are adjusted to heating mode state.Thus, can when meeting heating mode or refrigeration mode condition, air-conditioning can start fast from standby mode and run and freeze accordingly or heat, and improves response speed and the impression of user's comfortableness of air-conditioning.
Adopt this embodiment, air-conditioning enters automatic control mode according to the key control signal received, according to indoor light and indoor environment temperature selected suitable operational mode and target component startup optimization automatically, the indoor environment residing for user to be adjusted to automatically a comfortable state, achieve the one-touch manipulation to air-conditioning products.
As shown in Figure 2, this embodiment refrigeration mode comprises the steps:
Step 201: air-conditioning is started shooting, controls compressor operating.
Air-conditioning start after, by set according to user or acquiescence operational mode and operational factor, according to predetermined control program control compressor operating.
Step 202: judge whether compressor operating time reaches and set running time.If so, step 204 is performed; If not, step 203 is performed.
Wherein, setting running time is the time value prestoring, can call at any time, is obtained by special experiment condition and the test of special test means and be written to the numerical value in accumulator for air conditioner before air-conditioning dispatches from the factory, by air-conditioning research staff.
In air-conditioning, be provided with timer, timing can be carried out to the running time of compressor.Air-conditioning start, compressor starts run time, timer starts timing, when timing reach setting running time time, output time signal.In airconditioning control process, whether will reach according to compressor operating time and set running time, perform different control.Specifically, compressor operating time whether reach setting running time be the necessary condition determining whether to compensate indoor temperature.
Step 203: if step 202 judges that compressor operating time does not also reach set running time, conveniently control method controls compressor.
Namely, if compressor is started shooting, rear running time does not also reach and sets running time, then do not perform the process that indoor temperature compensates, but conveniently control method controls compressor yet.Wherein, conventional control methods refers to the control method of existing transducer air conditioning.Such as, the control method of existing air-conditioner is: the temperature difference between indoor temperature and indoor objects temperature is greater than when setting the temperature difference, controls compressor high frequency and runs, until the temperature difference of indoor temperature and indoor objects temperature is not more than the setting temperature difference.So, when compressor operating time does not also reach setting running time, if compressor wants high frequency to run in conventional control methods, then maintenance high frequency running status, make indoor temperature can approach indoor objects temperature fast, rapidly for user provides an indoor environment be comparatively suitable for.
Conveniently control method controls in compressor operating process, still constantly performs and judges whether compressor operating time reaches the process of setting running time.
Step 204: if step 202 judges that compressor operating time reaches set running time, will compensate indoor temperature, then, utilizes the indoor temperature after compensating to calculate the compressor frequency of room temperature PID control.
Specifically, running time after compressor start obtains the current indoor temperature that indoor temperature transmitter detects, as the first indoor temperature after reaching and setting running time, calculate the difference of the first indoor temperature and setting compensation temperature, as the second indoor temperature.
Wherein, setting compensation temperature is the temperature value prestoring, can call at any time, is also obtained by special experiment condition and the test of special test means and be written to the numerical value in accumulator for air conditioner before air-conditioning dispatches from the factory, by air-conditioning research staff.When reaching setting running time when the compressor is operating, meet condition indoor temperature being compensated to control, then obtain current indoor temperature detected by indoor temperature transmitter, using this current indoor temperature as the first indoor temperature.Then, obtain setting compensation temperature, calculate the difference of the first indoor temperature and setting compensation temperature, using this difference as the second indoor temperature.Then, step 105 is performed.
Step 205: the temperature difference calculating the second indoor temperature and indoor objects temperature, obtains the indoor temperature difference, carries out room temperature PID computing according to the indoor temperature difference, obtains compressor first object frequency.
Wherein, carry out room temperature PID computing according to the indoor temperature difference, obtain and can adopt prior art to realize to the concrete grammar of the target frequency that compressor controls.But unlike the prior art, the indoor temperature calculating the indoor temperature difference is not the temperature that indoor temperature transmitter detects, but the second indoor temperature obtained after temperature-compensating has been carried out to the temperature detected.
Step 206: whether the second indoor temperature that determining step 204 obtains is less than comfort temperature.If so, the dual PID performing step 208 and subsequent step controls; Otherwise the room temperature PID performing step 207 controls.
This step 206 can be carried out with step 204 and step 205 simultaneously, is divided into that to describe sequentially be only control procedure in order to clearly state this embodiment at this.After step 204 obtains the second indoor temperature, the comfort temperature of the second indoor temperature and setting is made comparisons, and judge whether the second indoor temperature is less than comfort temperature.Wherein, comfort temperature can be a default setting temperature of air-conditioning when dispatching from the factory, and also can be selected voluntarily by user and arrange design temperature.If by user's sets itself, air-conditioning can provide a reference temperature value, for reference.Such as, advise this comfort temperature to be set as 27 DEG C.
Step 207: if the second indoor temperature is not less than comfort temperature, performs room temperature PID and controls, according to first object FREQUENCY CONTROL compressor.
If step 206 judges that the second indoor temperature is not less than comfort temperature, show that now indoor temperature is higher, then perform room temperature PID and control, according to first object FREQUENCY CONTROL compressor, make indoor temperature fast cooling to indoor objects temperature.
Step 208: if the second indoor temperature is less than comfort temperature, performs dual PID and controls.
If step 206 judges that indoor temperature is less than comfort temperature, cause body sense uncomfortable for avoiding the too fast decline of temperature, perform dual PID to control, so that adjustment compressor operating frequency in time, make evaporator coil temperature can be stabilized to coil pipe target temperature, to adjust air conditioning exhausting temperature, reach cool and not cold comfortable air-out effect.The process that concrete dual PID controls is see the description of step 209 and step 210 below.
Step 209: the coil temperature detecting evaporimeter, carries out coiling warm PID arithmetic according to the coil pipe temperature difference, obtains the second target frequency.
The detection of the coil temperature of evaporimeter detects by set temperature sensor on evaporator coil.After detecting coil temperature, calculate the temperature difference between coil temperature and the coil pipe target temperature of setting, using this temperature difference as the coil pipe temperature difference.Wherein, coil pipe target temperature can be a default setting temperature of convertible frequency air-conditioner when dispatching from the factory, and can certainly be selected voluntarily by user and arrange design temperature.If by user's sets itself, because user is not very clear and definite for the concept of coil temperature and the performance indications of representative thereof, preferably provide a reference temperature value by convertible frequency air-conditioner, for reference selected.Such as, advise this coil pipe target temperature to be set as 14 DEG C.Then, carry out coiling warm PID arithmetic according to the coil pipe temperature difference, obtain the target frequency that compressor is controlled, and this target frequency is defined as the second target frequency.Coil warm PID arithmetic and obtain the method that can obtain compressor target frequency to the method for the target frequency that compressor controls with reference to room temperature PID computing of the prior art.Wherein, the original frequency coiling warm PID arithmetic can be the original frequency of a setting.Preferably, the original frequency coiling warm PID arithmetic is step: 106 judge that indoor temperature is less than comfort temperature, performs the current operation frequency of compressor when dual PID controls.And this current operation frequency is at least a running frequency after compressor operating a period of time (as 3min).
Step 210: the smaller value in the second target frequency that the first object frequency calculated according to step 205 and step 209 calculate controls compressor.
When indoor temperature is less than comfort temperature, warm PID arithmetic is coiled in coil pipe target temperature execution according to coil temperature and setting, and according to room temperature PID computing export first object frequency and coil warm PID arithmetic export the second target frequency in smaller value control compressor operating, while refrigeration cool-down, adjust coil temperature, coil temperature can be approached to coil pipe target temperature.
As previously indicated, when air-conditioner running refrigerating pattern, the temperature that indoor temperature transmitter detects is higher than the temperature in user's main activities space.If the temperature still detected according to indoor temperature transmitter participates in PID arithmetic as indoor temperature, indoor temperature difference during PID arithmetic is bigger than normal, the compressor target frequency calculated is higher, controls compressor and runs according to higher target frequency, cause air-conditioner energy consumption bigger than normal.And adopt the method for this embodiment, first the indoor temperature of detection is deducted a compensation temperature, obtain the second indoor temperature being less than the current indoor temperature of detection, and this second indoor temperature reflects the temperature in user's main activities space more realistically.When the second indoor temperature utilizing this less than normal participates in PID arithmetic, can obtain less compressor target frequency, the target frequency utilizing this less controls compressor operating, reduces energy consumption.And, because this second indoor temperature reflects the temperature in user's main activities space more realistically, thus, the indoor temperature after regulating also can be made more close to indoor design temperature, and there will not be the problem of overshoot, while satisfied temperature regulates comfortableness, reduce air-conditioner energy consumption.Meanwhile, by arranging comfort temperature, the second indoor temperature and comfort temperature being made comparisons, when indoor temperature is higher, adopts room temperature PID to control compressor operating, make indoor temperature fast cooling and approach indoor objects temperature.When indoor temperature is less than comfort temperature, adopt room temperature PID to control to control with the dual PID that controls of the warm PID of dish: just to enter coil warm PID control time, coil warm PID to control to play a major role, while cooling, preferentially make coil temperature rise to approach coil pipe target temperature; And when coil temperature is close to coil pipe target temperature, room temperature PID plays a major role, make indoor temperature be stabilized in indoor objects temperature, avoid causing because of room temperature overshoot air-conditioning to shut down the generation of phenomenon.Thus, in whole refrigeration control process, the basis approaching indoor objects temperature making indoor temperature making coil temperature approach coil pipe design temperature, both having met room temperature and having regulated, having realized again the comfortableness of air conditioning exhausting, reach cool and not cold refrigeration.
It should be noted that, in the process performing dual PID control, still constantly compare the size of the second indoor temperature and comfort temperature.Once indoor temperature is not less than comfort temperature, then exits dual PID control procedure, be transferred to room temperature PID control procedure.
And, in whole control procedure, not compressor runs the compensation just performing indoor temperature at the beginning, but first keep compressor conveniently control strategy operation, ensure that indoor temperature can conveniently control mode, rapidly near indoor objects temperature, the speed of indoor temperature comfort conditioning can not be affected.
As preferred embodiment, when indoor temperature is not less than comfort temperature and the difference of indoor temperature and comfort temperature is greater than the difference of setting, then exit dual PID control procedure, be transferred to room temperature PID control procedure.By the difference that choose reasonable sets, such as, be set as 1 DEG C, can guarantee that coil temperature is not less than coil pipe target temperature, ensure out cool and not cold comfortableness.
And, run in control procedure, if the non-wind speed setting of user at the air conditioner refrigerating of this embodiment, then control air-conditioning draught fan to run according to highest wind velocity, because under same refrigerating capacity, the leaving air temp of high wind speed is higher than the leaving air temp of low wind speed, guarantees that leaving air temp can not be too low further.And if the wind speed that user sets detected, then control blower fan according to setting wind speed run.
In the above-described embodiments, when performing the compensatory control of indoor temperature, perform how many temperature-compensatings to indoor temperature, is concern the key factor that air-conditioner controls comfortableness and energy saving.Also namely, setting selecting of running time and setting compensation temperature is key factor wherein.
As preferred embodiment, setting running time of prestore in air-conditioning, calling at any time is a running time corresponding with indoor objects temperature and outdoor temperature, and prestore, the setting compensation temperature called at any time is a compensation temperature corresponding with indoor objects temperature and outdoor temperature.Setting running time and setting compensation temperature is determined based on indoor objects temperature and outdoor temperature, can realize the Reasonable Regulation And Control of function of temperature compensation control on make-up time and degree of compensation based on operation of air conditioner load, reach the equilibrium of Thermal comfort adjustment and low energy consumption energy saving.
And what prestore in air-conditioning is indoor objects temperature range, outdoor temperature scope and the multiple running time corresponding with indoor objects temperature range and outdoor temperature scope and multiple compensation temperature.When performing function of temperature compensation control in operation of air conditioner process, setting running time and setting compensation temperature are called respectively by following process:
Set running time by following method call: the current indoor target temperature detected by indoor temperature transmitter is made comparisons with the indoor objects temperature range prestored, and judges the indoor objects temperature range belonging to current indoor target temperature; The current outdoor temperature detected by outdoor temperature sensor is made comparisons with the outdoor temperature scope prestored, and judges the outdoor temperature scope belonging to current outdoor temperature; According to searching in that prestore, corresponding with indoor objects temperature range and outdoor temperature scope multiple running times with the indoor objects temperature range belonging to current indoor target temperature and the outdoor temperature scope belonging to current outdoor temperature corresponding running time as setting running time, and call;
Setting compensation temperature is by following method call: current indoor target temperature and the indoor objects temperature range prestored are made comparisons, judge the indoor objects temperature range belonging to current indoor target temperature; Current outdoor temperature and the outdoor temperature scope prestored are made comparisons, judges the outdoor temperature scope belonging to current outdoor temperature; According to searching in that prestore, corresponding with indoor objects temperature range and outdoor temperature scope multiple compensation temperatures with the indoor objects temperature range belonging to current indoor target temperature and the corresponding compensation temperature of the outdoor temperature scope belonging to current outdoor temperature as setting compensation temperature, and call.
Certainly, in working control process, indoor objects temperature range belonging to current indoor target temperature and the outdoor temperature scope belonging to current outdoor temperature only need to judge once, then go to search according to result of determination and call corresponding setting running time and setting compensation temperature, and without the need to judging twice to affiliated scope, foregoing description is only in order to complete description calls the process of setting running time and setting compensation temperature.
The above-mentioned mode with temperature range is determined and is called setting running time and setting compensation temperature, and data processing amount is little, and control procedure is simple, is more conducive to carrying out controlling in time, effectively to air-conditioner, improves the speed that Thermal comfort regulates, and reduces operation energy consumption.
