Suppose that during the broiling summer, automobile berths after a period of time out of doors, vehicle interior temperature has reached 40--50 ℃.According to prior art, after the car owner need open driving engine into the car, open air conditioning for automobiles again and regulate temperature; If it is not long that the people leaves the car time, the car owner who has just can not kill engine and air-conditioning, does very like this and consumes energy.If but use the present invention, then the car owner need only prepare to enter in the love car first few minutes, with remote controller B with car in 200 meters the scope, by remote controller directly the master control system A in car send control information, (master control system A also can pass through the prior setting automatically regulating temperature of car owner---such as system can automatically regulating vehicle interior temperature between user's range of set temperature: 30--20 ℃), system will connect automobile power system 6-1-3 automatically, the starting ignition system, open driving engine 6-2-4 and air-conditioning 6-3-3, rapidly vehicle interior temperature is adjusted within the range of set temperature.Its process is as follows: air-conditioning is the necessary link of in time regulating vehicle interior temperature in the car owing to start, so when the user configures corresponding temperature value by remote controller (if or automobile control panel-people in car), and the instruction of sending the unlatching air-conditioning, system enters mode of operation immediately, as shown in Figure 3, the steps include:
1. system judges at first whether the user requires Energy Saving Control 101, in this way, then enter next step 103, whether promptly do not detect shifter bar at 0 grade.
2. infrared pickoff 7 will detect shifter bar and whether place 0 P PARK Position P, with the safety of guaranteeing to use.If shifter bar does not place 0 grade, then send warning signal 117, withdraw from the operation of the air-conditioning of unlatching, if place 0 grade then to enter next step,
3. system will connect the control end opening automobile power-supply system 6-1-3 of automobile power system relay 6-1-1; After 1 second, whether power supply opened detect 104, confirm to change next step immediately over to behind the power connection, otherwise system will send warning signal 117, jump out whole start-up routine,
4. judge whether the user requires Energy Saving Control 105, if, then enter 109, promptly do not start automotive engine,
5. system sends instruction: by automotive ignition relay 6-2-1, connect starter motor (electrical motor) power supply 106, starter motor 6-2-3 starts working.The time set of electrical motor work is 10S during each the startup.And when driving engine 6-2-4 started in the time that starter motor is set, system will close starter motor power supply 108 immediately, guarantee that starter motor can not damage because of overrunning; When the starter motor time of run can not make engine start above specific time, system was with the automatic cutout automobile power system, and 112 systems incite somebody to action once more power-on and make starter motor task again after waiting for 10 seconds, and such work will be carried out three times continuously.
6. if starter motor still can not make the driving engine normal operation through continuous three times running, though perhaps driving engine is launched, but its running condition mal 113, this moment, system was with the closing automobile power-supply system, withdraw from this start-up operation, and send and report to the police 117, if driving engine enters normal operation, then enter next step
7. close starter motor 108,
8. after a period of time, system sends the instruction 109 of opening air-conditioning, connects air conditioning switch relay 6-3-1,
9. similar to the 6th step, still can not normally move 115 through continuous three times opening automobile air-conditioning, perhaps air-conditioning is under the state of improper running, then system will send instruction and close air-conditioning, while closing automobile driving engine, automobile power system 114, and send and report to the police 117, withdraw from this start-up operation, if successfully enter next step.
10. be in the following time of state of normal operation when air-conditioning, system is with the signal 111 of feedback operation success.
By above step as can be seen, finished the startup of air-conditioning when system after, promptly finished testing simultaneously to automobile power system, starter motor, driving engine, electrical generator, and this system can apply to all processes of automobile normal operation and the whole process of air conditioning for automobiles running simultaneously, if in this process, break down in a certain position of automobile, the present invention also will send warning automatically, thereby improved car opertion efficient and safety performance widely, above-mentioned flow process also is adapted to the general startup automobile scavenger fan down of regulating.
Can enter the system temperature self-regulating process behind the starting of air conditioner, not close air-conditioning and must be more manually do not open or close into the car by car owner or other people.
Fig. 3 shows the process of system's remote manual control and automatically regulating temperature, and 200 expressions all can be sent automatic temperature-adjusting regulating command 223 or 201 by remote controller B or master control system A.By as can be known aforementioned, owing to adopted micro controller system and bi-directional communication modules, the outer remote controller information transmission of master control system A in the car and car is a beidirectional, compare with the temperature of user or default by the actual temperature inside and outside the car of various sensor acquisition through micro controller system, regulate algorithm E and general-purpose energy-saving automatic temperature-adjusting adjusting algorithm F according to general automatic temperature-adjusting, can judge needs refrigeration still to heat in the car, air-conditioning or scavenger fan need be opened or close; Its output signal can the follow procedure design open or close air-conditioning or scavenger fan.And whether the operation conditions that system also can detect air-conditioning or scavenger fan voluntarily is normal, unusually then reports to the police.Its working process is as follows:
After remote controller B or master control system A send the instruction of automatic temperature-adjusting adjusting, system controls opening or closing of air-conditioning or scavenger fan with following three kinds of modes, with automatic rising or reduce vehicle interior temperature: 1. general regulative mode 202 (not power save mode), 2. energy-conservation regulative mode 214,3., 4. remote controller direct control mode 223,231.Described power save mode promptly refers to not need to start automotive engine 6-2-4, and is directly powered to scavenger fan 6-4-3 or miniwatt air-conditioning 6-3-3 by automobile power system 6-1-3.
1. general regulative mode can start air-conditioning 204, also can start scavenger fan 203 (when the two splits).Control process is earlier will be by temperature, water tank, the sunshine recorder 8-1 to 8-4,7,9 of the inside and outside setting of car, and collecting temperature data 205 are sent into micro controller system 1A, and micro controller system is judged the needs startup according to the E algorithm of automatic temperature-control and still closed air-conditioning or scavenger fan.Start as need, then, connect automobile power system 6-1-3 207 by starting AUTOMOTIVE RELAY coil 6-1-1, closed its switch 6-1-2.In like manner, restart automotive engine 6-1-4 208, start air-conditioning 6-3-3 or scavenger fan 6-4-3 then.Close air-conditioning or scavenger fan as need, then system will judge that also whether air-conditioning is turning round 210, in running, then carries out 211 and closes air-conditioning or scavenger fan, closing automobile power-supply system 212 in this way.No matter be to start or close air-conditioning or scavenger fan, system all will check and have or not other control signal 213, if any, enter 229, otherwise return 205, continue the collecting temperature signal and carry out automatic temperature-control;
2. energy-conservation regulative mode 214: the special energy-conservation miniwatt air-conditioning of only controlling scavenger fan or directly driving by automobile power system.Similar to general regulative mode, also need pick-up transducers data 215, judge the needs startup according to automatic temperature-control E, F algorithm 216 and still close scavenger fan or special energy-conservation miniwatt air-conditioning.Start as need, then directly start automobile power system 217 and scavenger fan 218.Close as need, need check equally also then whether scavenger fan is turning round 219, then enters 220,221,222 as turning round, and closes air-conditioning, as stop then directly jumping to 222;
3. remote controller direct control mode: this method is sent the instruction 223 that starts air-conditioning or scavenger fan by remote controller B, after master control system A receives, handles, can directly open automobile power system 224, judge 225 through power save mode, as not energy-conservation, then open automotive engine 226 earlier, open air-conditioning or scavenger fan 227 again; As energy-conservation, then directly open air-conditioning or scavenger fan 227.
4. remote controller B also can directly start automotive engine 6-2-4, can finish through step 231,232,233,234.
In above-mentioned general regulative mode and the energy-conservation regulative mode, the present invention is provided with general automatic temperature-adjusting and regulates algorithm E and two kinds of algorithms of general-purpose energy-saving automatic temperature-adjusting adjusting algorithm F, is illustrated by Fig. 9, Figure 10 respectively.Fig. 9 shows general automatic temperature-adjusting and regulates algorithm E diagram of circuit, this algorithm at first has been set by the user air conditioner refrigerating and has started, stopped temperature BC, SC, the air conditioner refrigerating warm start, stop temperature BH, SH, otherwise master control system will adopt the numerical value 300 of systemic presupposition.Such as, system can be set at: BC is a numerical value between 30 to 40 degree, and SC is the poor of BC and X; SH is BH and X sum.Wherein must satisfy SC＞SH.X be one of default greater than, equal 4, less than, equal 10 numerical value, can adjust according to the intensity at sunshine and the water temperature of water tank: during refrigeration, intensity of sunshine is strong more, and then the X value is big more; Sunshine is weak more, and then the X value is more little.When heating, the water tank water temperature is low more, and then the X value is big more; The water tank water temperature is high more, and then the X value is more little.Then according to the different needs of system's cooling and warming, vehicle interior temperature aviation value AT 308 that different C.T CT 304,305,306,307 collects according to master control system A at last is set to be compared with different C.T CT, with reference to the running condition of current air-conditioning, determine opening or closing of air-conditioning.
If by Fig. 9,11 as can be seen the householder set or master control system A self sets and adopts the mode of refrigeration that the temperature in the car is remained between 30 ℃-20 ℃ by remote controller is remote in summer, then divide two kinds of situations:
1. when air-conditioning is out of service, it is starting of air conditioner temperature BC that system chooses C.T CT, by two interior sensor 8-1 that are provided with in the automobile, the aviation value that 8-2 gathers actual temperature numerical value is made as AT, aviation value AT and C.T CT (starting of air conditioner temperature BC) are compared, with reference to season and by sunshine, sensors such as water tank temperature 9, the detected actual temperature value of 8-4, if X=4, BC=32, then SC=BC-X=28 establishes vehicle interior temperature aviation value AT greater than C.T CT, as AT=35 ℃, CT=BC=32 ℃, SC=28 ℃, by step 300-301-302-304-308-310-312-316 as can be seen, at vehicle interior temperature aviation value AT greater than air conditioner refrigerating start-up temperature BC, need refrigeration, and this moment, air-conditioning was out of service, and then system enters 316, started air-conditioning.As judging that through 312 air-conditionings move, then return through 320, continue refrigeration, step is 300-301-302-304-308-312-320.If AT=31 ℃ of the indoor actual average temperature of automobile, during less than C.T CT (air conditioner refrigerating start-up temperature BC), air-conditioning will can not start, and step is 300-301-30-304-308-310-313-320.
When 2. air-conditioning was moving, the then selected C.T CT of system equaled air conditioner refrigerating and stops temperature SC.Two kinds of situations of same branch, look vehicle interior temperature aviation value AT is higher than or being lower than air conditioner refrigerating stops temperature SC, if average temperatures AT also promptly freezes greater than C.T CT and stops temperature SC, as AT=31 ℃ of this moment, judge that through step 302-305-308-310-312 air-conditioning should return 320 and continue refrigeration.Otherwise if AT=26 ℃ of this moment, be lower than C.T CT also promptly refrigeration stop temperature SC, judge that air-conditioning still in operation, then should enter 317 and close air-conditioning through 313, step is 300-301-302-305-308-310-313-317-320.Because of temperature AT has entered in the temperature control zone.Actual temp is set by accompanying drawing 11 as can be seen.
Under the situation that air-conditioning heats, system heats actual temperature aviation value AT in the car startup with air-conditioning, stops temperature BH, SH and compare, if actual temperature AT is lower than when heating start-up temperature BH, if then air-conditioning stops, then enters 318 and starts air-conditionings.Stop temperature SH if instead actual temperature AT is higher than to heat, also in operation, then enter 319, close air-conditioning, because entered temperature controlled region this moment as air-conditioning.
Figure 10 shows the general-purpose energy-saving automatic temperature-adjusting and regulates algorithm F diagram of circuit, and what Figure 12 showed it stops to follow the tracks of temperature embodiment automatically, and it only is applicable to automobile power system and directly starts scavenger fan or special energy-conservation miniwatt air-conditioning.Equally, the user at first must set to start automatically and follow the tracks of temperature value BTT, stops to follow the tracks of temperature value STT automatically, or puts two values with systemic presupposition.Such as, system can be set at: automatically start follow the tracks of temperature value BTT for greater than, equal 4, less than, equal 10 a numerical value, stop to follow the tracks of temperature value STT automatically and equal to start and follow the tracks of the poor of temperature BTT and X.Wherein X be one of default less than, equal 5 numerical value, adjust according to the intensity at sunshine and the water temperature of water tank as algorithm E.Its dominant ideas are no matter winter or summer, with indoor and outdoor temperature difference order of magnitude, and with automatic startup with stop to follow the tracks of the contrast of temperature automatically, decision startup or close scavenger fan and will monitor scavenger fan and whether really open or close with program step.The inside and outside temperature difference absolute value of car is followed the tracks of temperature BTT greater than starting automatically, starts scavenger fan, and is also little if car internal-external temperature difference absolute value ratio stops to follow the tracks of temperature value STT, illustrates that car internal and external temperature value is close, then turns off scavenger fan.Divide two kinds of situations:
1. scavenger fan stops; getting C.T CT and equal start to follow the tracks of temperature value BTT402; by temperature sensor 8-1; 8-2 gathers two indoor temperatures; get its aviation value ATI; sensor 8-3 gathers outdoor temperature value ATO404; the absolute value of the difference of the two is followed the tracks of temperature BTT and compared 405 with starting automatically; with reference to season with by sunshine; sensors such as water tank temperature 9; the detected actual temperature value of 8-4; establish X=5; BTT=10; STT=BTT-X=5 then; establish ATI=43 ℃ of vehicle interior temperature aviation value; the outer temperature of car is ATO=30 ℃, this moment, the absolute value of difference of ATI and ATO was 13, the absolute value of the difference of the two is followed the tracks of temperature BTT=10 greater than starting automatically; need to start scavenger fan 408; on the contrary the absolute value of the difference of the two less than the warm BTT=10 of startup tracking automatically, as ATI=37 ℃, step is 400-401-402-404-405-406-408-410.Other conditions are constant, then temporarily do not start scavenger fan, and step is 400-401-403-404-405-407-409-410.
1. scavenger fan moves; get C.T CT and equal to stop automatically following the tracks of temperature STT=5; in car; the absolute value of the difference of outer temperature is greater than stopping to follow the tracks of temperature STT=5; as ATI=37 ℃ of vehicle interior temperature aviation value; the outer temperature of car is ATO=30 ℃, by as can be known aforementioned, establishes: BTT=10; STT=5; this moment, the absolute value of difference of ATI and ATO was 7, and the absolute value of the difference of the two then directly returns 410 greater than stopping to follow the tracks of temperature STT=5 automatically; step is: 401-403-404-405-406-410; when the car internal-external temperature difference less than stopping to follow the tracks of temperature, as ATI=32 ℃, other conditions are constant; if then at this moment scavenger fan move; then close, because of indoor/outdoor temperature-difference is very little, then close scavenger fan; step is: 401-403-404-405-407-409-410, as shown in figure 12.
