Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in more detail.
The present embodiment, for refrigerator product, is explained in detail the automatic identifying method of frequency conversion and constant speed compressor.
The refrigerator product of the present embodiment is in order to reduce material variety, convenient management, General design is carried out to the master control borad in refrigerator, master control borad is designed for the drive circuit (such as constant speed compressor being carried out to the relay etc. of on off control) that drives constant speed compressor to run and the primary processor of control signal needed for running for the drive circuit that drives frequency-changeable compressor to run and for generation of frequency-changeable compressor and constant speed compressor simultaneously.In order to reach energy-saving and cost-reducing purpose of design further, enabling the type of compressor of the different driving circuit on master control borad selected by refrigerator automatically realize selecting to start, needing master control borad to realize automatically identifying to selected type of compressor.In order to reach this purpose of design, the present embodiment arranges test circuit and first interface XP101 on master control borad, shown in Figure 1.Test circuit is split into two-part, and by two-part tie point separately, connects one to one with the pin of two in first interface XP101 1,3 respectively.Frequency conversion plate for connecting frequency-changeable compressor arranging circuit, making frequency conversion plate when being connected on first interface XP101, just two-part of described test circuit are connected.Specifically can the second interface XP201 be set on frequency conversion plate, communication line is designed between the pin 1 and pin 3 of the second interface XP201, like this, after master control borad and frequency conversion plate are linked together by first interface XP101 and the second interface XP201, two-part of test circuit are connected by the communication line on frequency conversion plate, and whether the signal circuit detecting described test circuit is connected, if connect, then think that frequency conversion plate is connected on master control borad, the compressor namely selected by refrigerator is frequency-changeable compressor; If access failure, then think that frequency conversion plate does not connect, the compressor namely selected by refrigerator is constant speed compressor.Thus, the automatic identification of master control borad to frequency conversion and constant speed compressor is just achieved.
For the communication line on the test circuit on master control borad and frequency conversion plate, multiple design can be adopted.Such as: the test circuit described in resistance R and DC electrical source+5V structure can be adopted, shown in Figure 1, DC electrical source+5V is connected the pin 1 of first interface XP101, by the pin 3 contact resistance R of first interface XP101, and by described resistance R ground connection.Adopt a wire as described communication line, be arranged on frequency conversion plate, and between the pin 1 being connected to the second interface XP201 and pin 3.Carry out input to the pin 3 of first interface XP101, if low level, then represent that two-part of test circuit are not connected, namely frequency conversion plate is not connected on master control borad, now can judge selected by refrigerator to be constant speed compressor; If the level of pin 3 is high, then represent that DC electrical source+5V and resistance R connect, namely frequency conversion plate is connected with master control borad, now can judge that frequency-changeable compressor selected by refrigerator.Thus, the accurate identification of master control borad to type of compressor is just achieved.
Adopt this test circuit design, need on master control borad, increase extra hardware circuit, therefore easily cause the rising of system hardware cost.In order to address this problem, the present embodiment preferably adopts and existingly on master control borad carries out amplifying the drive circuit of process as described test circuit for what export primary processor for the control signal driving frequency-changeable compressor to run.Described drive circuit is split, such as, is divided into two-part, and by two-part tie point separately, connect one to one for two the different pins 1,3 connected in the first interface XP101 of frequency conversion plate respectively from master control borad.After described drive circuit splits, two-part can not work alone, and the control signal that cannot export primary processor be carried out drivings and be processed, therefore can not control signal after output processing.Utilize this characteristic, as long as slightly design on frequency conversion plate, when making frequency conversion plate on the first interface XP101 being connected to master control borad, utilize the circuit on frequency conversion plate that two-part of described drive circuit are connected, described drive circuit is put into operation, and then control signal after output processing transfer to frequency conversion plate via one of them pin 3 of first interface XP101.Thus, while meeting frequency-changeable compressor drived control, whether only need detect has the control signal after process to export by described drive circuit, namely the signal for the identical type of control signal that drives frequency-changeable compressor to run exported with primary processor whether detected, just can pick out master control borad and whether be connected with frequency conversion plate; If master control borad is connected with frequency conversion plate, then can think that what select is frequency-changeable compressor; Otherwise, just can think that what select is constant speed compressor, just achieve the automatic identification of master control borad to frequency conversion and constant speed compressor thus.
As a kind of decision design mode of described drive circuit, the present embodiment adopts an a NPN type triode V1 and DC electrical source+5V, coordinates simple peripheral circuit, the drive circuit described in structure, driving process is carried out to the control signal that primary processor exports, shown in Figure 2.Described DC electrical source+5V is connected the pin 1 of first interface XP101 by current-limiting resistance R1; The base stage of NPN type triode V1 being connected the RA1 port of primary processor by resistance R3, receiving the control signal for driving frequency-changeable compressor to run that primary processor exports, the pulse signal of such as frequency-adjustable or the adjustable pwm signal of dutycycle; By the grounded-emitter connection of NPN type triode V1, collector electrode connects the pin 3 of first interface XP101, and by pin 3 by pull down resistor R5 ground connection.Like this, when constant speed compressor selected by refrigerator, because the first interface XP101 of master control borad suspends, namely do not connect frequency conversion plate, therefore the pin 1,3 of first interface XP101 is not communicated with.Now, no matter primary processor exports the control signal of which kind of level by its RA1 port, the equal remain off state of NPN type triode, and pin 3, by pull down resistor R5 ground connection, remains low level state.And when frequency-changeable compressor selected by refrigerator, because the first interface XP101 of master control borad connects frequency conversion plate, by the circuit on frequency conversion plate, the pin 1 of first interface XP101 is communicated with pin 3, thus make DC electrical source+5V transfer to the collector electrode of NPN type triode V1, drive circuit is connected and puts into operation.Now, when primary processor is high level by the control signal that its RA1 port exports, controls NPN type triode V1 saturation conduction, drag down the current potential of pin 3, by pin 3 to frequency conversion plate output low level signal; And when primary processor is low level by the control signal that its RA1 port exports, then NPN type triode V1 cut-off, the current potential on pin 3 is the dividing potential drop of the right+5V DC electrical source of resistance R1, R5, is therefore high level by pin 3 to the signal that frequency conversion plate exports.This shows, when frequency-changeable compressor selected by refrigerator, the control signal being exported to frequency conversion plate by first interface XP101 and primary processor are the signal of identical type by the control signal that its RA1 port exports, and are namely pulse signal or pwm signal, and just phase place is contrary.Therefore, primary processor by regulating its frequency of pulse signal exported or dutycycle of pwm signal, can realize the adjustment to frequency-changeable compressor frequency of okperation.
Because the pin 3 of first interface XP101 remains low potential when master control borad does not connect frequency conversion plate, what transmit after master control borad connects frequency conversion plate is then pulse signal, therefore, can using pin 3 as test point A, as long as detect the level state of test point A, can judge whether master control borad is connected with frequency conversion plate; If be connected with frequency conversion plate, then can think that what select is frequency-changeable compressor; If be not connected with frequency conversion plate, then can think that what select is constant speed compressor.The present embodiment utilizes an other road port RA0 of primary processor to connect the pin 3 of first interface XP101 by resistance R2, the potential state of read test point A, thus realizes the automatic identification to type of compressor selected by refrigerator.
Certainly, described drive circuit also can adopt other circuit design modes, such as utilizes PNP type triode or other switching elements to coordinate DC electrical source to set up and forms.Described drive circuit is split into two-part from the Nodes of the control signal after output processing, and guarantee drive circuit only ability startup optimization after two-part are connected, by two-part tie point separately, connect one to one from the different pin of two in first interface XP101 respectively, just can meet the designing requirement of the present embodiment thus.Therefore, the specific design mode of the present embodiment to drive circuit is not limited in above citing.
In frequency conversion plate side, in order to make frequency conversion plate when being connected on master control borad, the pin 1,3 in first interface XP101 can be connected on the one hand, being used in the drive circuit driving frequency-changeable compressor to run and putting into operation; The control signal that control panel exports can be transferred to frequency-changeable compressor on the other hand, realize the effective adjustment to frequency-changeable compressor frequency of okperation, first the present embodiment is designed for the second interface XP201 connecting master control borad on frequency conversion plate, shown in Figure 2, in described second interface XP201, the collocation form of each pin is identical with the collocation form of each pin in first interface XP101, interface can be adopted to dock or connection that the mode of external winding displacement realizes between master control borad and frequency conversion plate.Then, frequency conversion plate arranges optocoupler N201, the anode of light emitting diode in optocoupler N201 is connected the pin 1 of the second interface XP201, the negative electrode of Light-Emitting Diode (LED) is connected the pin 3 of the second interface, after the second interface XP201 is connected with first interface XP101, DC electrical source+5V on master control borad is communicated with the collector electrode of NPN type triode V2 by the light emitting diode in optocoupler N201, two-part master control borad being used for the drive circuit driving frequency-changeable compressor to run are connected, described drive circuit is put into operation, what export primary processor carries out amplification process for the control signal driving frequency-changeable compressor to run, then the negative electrode of Light-Emitting Diode (LED) in optocoupler N201 is transferred to, be low level or high level by putting the cathode potential of Light-Emitting Diode (LED), thus the break-make sequential of Light-Emitting Diode (LED) is controlled.By the grounded-emitter connection of illuminated triode in optocoupler N201, collector electrode connects+5V DC electrical source by current-limiting resistance R201, and connects the single-chip microcomputer on frequency conversion plate by resistance R202.When Light-Emitting Diode (LED) conducting in optocoupler N201 is luminous, illuminated triode conducting, drags down the current potential of single-chip microcomputer middle port RB0; When Light-Emitting Diode (LED) in optocoupler N201 turns off extinguishing, illuminated triode ends, and+5V DC electrical source acts on the port RB0 of single-chip microcomputer by resistance R201, R202, makes the current potential of port RB0 for high.The pulse signal that single-chip microcomputer receives according to its port RB0, output drive signal, to frequency-changeable compressor, drives frequency-changeable compressor startup optimization, and realizes automatically regulating to the frequency of okperation of compressor.
In the present embodiment, adopt the drive circuit through splitting on optocoupler N201 connection master control borad, while meeting the automatic identification requirement of type of compressor, Phototube Coupling process can also be carried out to the control signal that master control borad exports, to avoid the electronic circuit on frequency conversion plate to be damaged, frequency conversion plate is played to the effect of safety protection.
Below in conjunction with the hardware circuit shown in Fig. 2, the Software for Design flow process of frequency conversion and constant speed compressor automatic identifying method is explained in detail.
Shown in composition graphs 3, primary processor is after refrigerator startup optimization, first by its port RA1 output pulse signal (or pwm signal), preferably exporting the pulse signal (or pwm signal) for driving frequency-changeable compressor full speed running, then detecting the level state of its port RA0.
If port RA0 receives pulse signal (or pwm signal), then judge that compressor selected by refrigerator is as frequency-changeable compressor.Now, primary processor outputs control signals on master control borad out of service for the drive circuit driving constant speed compressor to run, such as, control constant speed compressor and drive relay power-off, to reach the purpose of design reducing power consumption.Experiment proves, can about energy efficient 1W.Meanwhile, according to the performance characteristic of constant speed compressor and frequency-changeable compressor, can also write different parameter values to the cooling parameters in compressor control program, such as, be 1 by the start-stop of refrigerator point optimum configurations, to reach the maximum utilization of refrigeration for refrigerator efficiency.
In the present embodiment, the cooling parameters of constant speed compressor and the cooling parameters of frequency-changeable compressor can be preserved in advance in primary processor.When the primary processor compressor identified selected by refrigerator is frequency-changeable compressor, directly can transfer the cooling parameters of the frequency-changeable compressor preserved in advance, the starting point of frequency-changeable compressor and break point are controlled.And when the primary processor compressor identified selected by refrigerator is constant speed compressor, the cooling parameters of the constant speed compressor preserved in advance directly can be transferred, the starting point of compressor and break point are adjusted.By being the different refrigeration control parameter of dissimilar compressor configuration, to realize the optimization of compressor efficiency.
After this, primary processor is according to the refrigerator room temperature situation of temperature sensor feedback, and the frequency (or dutycycle of pwm signal) of the pulse signal automatically regulating its port RA0 to export, to realize the automatic adjustment to frequency-changeable compressor frequency of okperation.
If primary processor detects that the current potential of its port RA0 is always low, then judge that compressor selected by refrigerator is as constant speed compressor.Now, the signal that primary processor turns off its port RA1 exports, the road port utilizing it independent exports the control signal for driving constant speed compressor to run, and controls the drive circuit startup optimization for driving constant speed compressor to run on master control borad, realizes the on off control to constant speed compressor.Meanwhile, transferring the cooling parameters of the constant speed compressor preserved in advance, be configured the cooling parameters in compressor control program, such as, is 2 by the start-stop of refrigerator point optimum configurations, to improve the accuracy that start/stop of compressor controls.
Frequency conversion of the present invention and constant speed compressor automatic identification technology, whether connected by the signal circuit detected on master control borad, thus can to automatically identify driven compressor be constant speed compressor or frequency-changeable compressor, solve frequency conversion and constant speed compressor thus when sharing one piece of master control borad, due to the extra power consumption problem not selecting the drive circuit continuous service corresponding to compressor to bring, while effective energy saving, the independence achieving frequency conversion and constant speed compressor refrigeration control parameter is arranged, and achieves the optimization of compression mechanism cold efficiency.
It is to be noted, frequency conversion proposed by the invention and constant speed compressor automatic identification technology, be not only applicable to refrigerator product, need other electronic products configuring frequency conversion or constant speed compressor applicable equally for air-conditioning etc., the present invention does not specifically limit this.
