Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of depurator autocontrol method, and this depurator autocontrol method is applied to depurator, it is also possible to be applied to have air cleaning can the equipment such as air-conditioner.
With reference to the schematic flow sheet that Fig. 1, Fig. 1 are depurator autocontrol method one embodiment of the present invention.
In one embodiment, the depurator autocontrol method of the present invention comprises the following steps:
Step S10: when depurator start runs, the state of detection depurator overhead door, and the State-output according to described overhead door detect signal.
In depurator start running, the overhead door of depurator should be at complete raised configuration under normal circumstances, is opened by the air outlet of depurator so that depurator can pass through its air outlet.Thus starting shooting under running status at depurator; for guaranteeing that depurator is properly functioning and does not damage because overhead door is abnormal; the present embodiment is by detecting the state of depurator overhead door; and detect signal accordingly according to the State-output that overhead door is current; with when detecting that overhead door occurs abnormal; control depurator automatic shutdown, enter depurator guard mode.
The present embodiment is set in and detects when overhead door rises above a predeterminated position, it is judged that overhead door is in normal condition, and output level state is preset the detection signal of shutdown level；When detecting that overhead door is decreased below above-mentioned predeterminated position, it is judged that overhead door is in abnormality, output level state is preset the detection signal of start level.Specifically, above-mentioned default shutdown level is low level, and above-mentioned default start level is high level.
Step S20: detect the level state of described detection signal, when the level state of described detection signal is for presetting shutdown level, it is determined that described overhead door occurs abnormal, controls depurator shutdown.
In the state of detection depurator overhead door, and after output corresponding detection signal, by detecting the level state of this detection signal, it may be determined that the state that overhead door is current, and then determine whether to control depurator automatic shutdown.
Owing to starting shooting in running at depurator, detect when overhead door is in abnormality, the level state of the detection signal of output is for presetting start level, thus, when detecting the level state of described detection signal, if detecting, the level state of this detection signal is for presetting shutdown level, it is determined that now overhead door occurs abnormal, controls depurator shutdown.
Thus; if starting shooting under running status at depurator; occur that overhead door is constantly in closed mode, the air outlet of depurator is blocked, or overhead door is artificially forced down pressure and the air outlet of lower general who has surrendered's depurator such as blocks at the abnormal conditions; then control depurator automatic shutdown; making depurator be in guard mode, now the blower fan of depurator is out of service, thus avoiding owing to air outlet is closed; blower fan still runs and causes that noise increases, and it also avoid the parts damages such as the motor of depurator, blower fan.
On the contrary, if starting shooting under running status at depurator, detect that the level state of detection signal is for presetting start level, then illustrate that now overhead door is in normal condition, be namely in complete raised configuration, now control depurator and maintain running status of currently starting shooting.
Depurator autocontrol method provided by the invention, first when depurator start runs, the state of detection depurator overhead door, and the State-output according to described overhead door detects signal, then the level state of this detection signal is detected, when the level state detecting signal shuts down level for presetting, determine that described overhead door occurs abnormal, control depurator shutdown, thus realizing depurator automatic shutdown when overhead door occurs abnormal, depurator air outlet under open state is avoided to be blocked and increase noise, guarantee that the parts such as motor of depurator do not damage because overhead door is abnormal, it is thus possible to extend the service life of depurator.
Referring again to Fig. 2, Fig. 2 is the schematic flow sheet of step S10 in Fig. 1.
As in figure 2 it is shown, the step S10 in Fig. 1 includes:
Step S11: when depurator start runs, after a Preset Time, the state of detection depurator overhead door.
When just starting shooting due to depurator, the blower fan of depurator has been turned on, and now overhead door should be at complete raised configuration under normal circumstances, now by the state of detection overhead door, it can be determined that whether overhead door exception occurs.The present embodiment, when depurator start runs, detects the state of overhead door again, it can be ensured that overhead door is in normal condition after Preset Time, and namely overhead door is in complete raised configuration, is located higher than above-mentioned predeterminated position, it is to avoid the state of erroneous judgement overhead door.In actual applications, can be set in depurator start after Preset Time open blower fan so that overhead door rise completely after air-out eloquence air-out.
Above-mentioned Preset Time can according to the speed of service of overhead door and travel settings, this Preset Time is preferably set for the time needed for rising to extreme higher position more than or equal to overhead door from extreme lower position, such as overhead door rise to extreme higher position from extreme lower position needed for time be 30s, after 30s started shooting by depurator, then detect the state of overhead door again, to guarantee when starting the state detecting overhead door, overhead door, already at complete raised configuration, is located higher than above-mentioned predeterminated position, it is ensured that testing result is accurate.
Step S12: judge whether described overhead door is in abnormality.
In the state procedure of detection depurator overhead door, the state of the depurator overhead door detected should be normal condition or abnormality, therefore when detecting the state of depurator overhead door, it is judged that whether overhead door is in abnormality, if described overhead door is in abnormality, then enter step S13；If described overhead door is in normal condition, then enter step S14.
Step S13: output level state is preset the detection signal of shutdown level.
When detecting that overhead door is in abnormality, fault as own in overhead door and be constantly in closed mode, position is lower than above-mentioned predeterminated position, the air outlet of depurator is blocked, or overhead door is pressed under being forced and is decreased below above-mentioned predeterminated position, when blocking the air outlet of depurator, the level state of the detection signal of output is for presetting shutdown level.
Step S14: output level state is preset the detection signal of start level.
On the contrary, when detecting that overhead door is in normal condition, namely overhead door is already at complete raised configuration, is located higher than above-mentioned predeterminated position, and when making the normal air-out of the air outlet of depurator, the level state of the detection signal of output is for presetting start level.
Referring again to Fig. 3, Fig. 3 is the schematic flow sheet of step S20 in Fig. 1.
As it is shown on figure 3, the step S20 in Fig. 1 includes:
Step S21: detect the level state of described detection signal.
After detecting state the output corresponding detection signal of overhead door in step 10, need to detect the level state of this detection signal, determine the state of overhead door with the level state according to this detection signal for presetting start level or default shutdown level, and then judge that overhead door is in normal condition or abnormality.
Step S22: when the level state described detection signal being detected is preset shutdown level always, it is determined that described overhead door is constantly in closed mode, controls depurator shutdown.
When running due to depurator start, if overhead door is in normal condition, then the level state of described detection signal is for presetting start level.Therefore; in the level state process detecting described detection signal; if detecting, the level state of described detection signal is always for presetting shutdown level; then illustrate that overhead door is constantly in lower than above-mentioned predeterminated position; the perfect condition that now should be at being higher than above-mentioned predeterminated position with overhead door is not inconsistent; thus it is abnormal to judge that overhead door occurs, now control depurator shutdown, make depurator automatic shutdown enter guard mode.
Step S23: when the level state described detection signal being detected is become presetting shutdown level from presetting start level, and when being not detected by shutdown command, it is determined that described overhead door is in and is forced pressed status, controls depurator shutdown.
In like manner, in the level state process detecting described detection signal, if detecting, the level state of described detection signal is from the situation presetting start level and become presetting shutdown level, then illustrate that overhead door is decreased below predeterminated position from higher than predeterminated position, namely overhead door becomes closed mode from raised configuration, if being now not detected by shutdown command, then illustrate that overhead door is not that depurator to shut down and to decline, now it is judged as that elevator is pressed under being forced and declined, thus it is abnormal to judge that overhead door occurs, now control depurator shutdown, depurator automatic shutdown is made to enter guard mode.
Refer again to the schematic flow sheet that Fig. 4, Fig. 4 are depurator another embodiment of autocontrol method of the present invention.
Based on above-described embodiment, as shown in Figure 4, in another embodiment of depurator autocontrol method of the present invention, also include after step S20:
Step S30: when start-up command being detected, controls described overhead door and rises, make described overhead door be in complete raised configuration.
When pressing under overhead door is forced, if overhead door does not drop to extreme lower position, namely overhead door does not run a complete stroke, then when depurator causes start because overhead door is forced to press down after automatic shutdown, overhead door will rise less than extreme higher position, be not in complete raised configuration.Such as, the rise stroke of overhead door is to run 150 degree clockwise under normal circumstances, then after overhead door rises, if the situation of normal shutdown, then overhead door needs to run 150 degree counterclockwise, and overhead door just can be made in the completely closed state；If overhead door is down pressed by external force, and make the situation of depurator automatic shutdown, if overhead door has only run 20 degree counterclockwise when depurator shuts down, if now detecting, start-up command after-purification device is started shooting at once, owing to when depurator shuts down, overhead door has only run 20 degree counterclockwise, therefore, when depurator is started shooting again, overhead door only runs 20 degree clockwise, namely think that overhead door is already at complete raised configuration, but actually now overhead door does not rise completely.
Thus, during for preventing depurator from again starting shooting after automatic shutdown because overhead door is forced to press down, start shooting immediately after start-up command being detected, then there is no complete raised configuration owing to overhead door is in, and cause the misjudgment phenomenon to overhead door state, the present embodiment is detecting that overhead door occurs extremely, after depurator automatic shutdown, if start-up command being detected, then need first to control overhead door to rise, described overhead door is made to run a complete upward stroke, overhead door is made again to reset, it is in complete raised configuration, control depurator starting up's fan operation again, guarantee the normal air-out of air outlet of depurator, guarantee that depurator normally can stably run and not damage because of overhead door fault.
The present invention also provides for a kind of depurator automaton.
With reference to the structural representation that Fig. 5, Fig. 5 are depurator automaton one embodiment of the present invention.
In depurator automaton one embodiment of the present invention, as it is shown in figure 5, described depurator automaton includes position detecting module 100 and switching on and shutting down control module 200.
Wherein, position detecting module 100 is for when depurator start runs, detecting the state of depurator overhead door, and the State-output according to described overhead door detects signal.
In depurator start running, the overhead door of depurator should be at complete raised configuration under normal circumstances, is opened by the air outlet of depurator so that depurator can pass through its air outlet.Thus starting shooting under running status at depurator; for guaranteeing that depurator is properly functioning and does not damage because overhead door is abnormal; the present embodiment detects the state of depurator overhead door by position detecting module 100; and detect signal accordingly according to the State-output that overhead door is current; with when detecting that overhead door occurs abnormal; control depurator automatic shutdown, enter depurator guard mode.
The present embodiment is set in and detects when overhead door rises above a predeterminated position, it is judged that overhead door is in normal condition, and output level state is preset the detection signal of shutdown level；When detecting that overhead door is decreased below above-mentioned predeterminated position, it is judged that overhead door is in abnormality, output level state is preset the detection signal of start level.Specifically, above-mentioned default shutdown level is low level, and above-mentioned default start level is high level.
Switching on and shutting down control module 200 for detecting the level state of described detection signal, when the level state of described detection signal is for presetting shutdown level, it is determined that described overhead door occurs abnormal, control depurator shutdown.
The state of depurator overhead door is detected in position detecting module 100, and after exporting corresponding detection signal, the present embodiment controls module 200 by switching on and shutting down and detects the level state of this detection signal, it may be determined that the state that overhead door is current, and then determines whether to control depurator automatic shutdown.
Owing to starting shooting in running at depurator, position detecting module 100 detects when overhead door is in abnormality, the level state of the detection signal of output is for presetting start level, thus, switching on and shutting down control module 200 when detecting the level state of described detection signal, if detecting, the level state of this detection signal is for presetting shutdown level, it is determined that now overhead door occurs abnormal, controls depurator shutdown.
Thus; if starting shooting under running status at depurator; occur that overhead door is constantly in closed mode; the air outlet of depurator is blocked; or overhead door is artificially forced down pressure and the air outlet of lower general who has surrendered's depurator such as blocks at the abnormal conditions; then switching on and shutting down control module 200 and control depurator automatic shutdown; depurator is made to be in guard mode; now the blower fan of depurator is out of service; thus avoiding owing to air outlet is closed; blower fan still runs and causes that noise increases, and it also avoid the parts damages such as the motor of depurator, blower fan.
On the contrary, if starting shooting under running status at depurator, switching on and shutting down control module 200 and detect that the level state of detection signal is for presetting start level, then illustrate that now overhead door is in normal condition, namely overhead door is in complete raised configuration, and now switching on and shutting down control module 200 controls depurator and maintains running status of currently starting shooting.
Depurator automaton provided by the invention, when depurator start runs, the state of depurator overhead door is detected by position detecting module 100, and the State-output according to described overhead door detects signal, then pass through switching on and shutting down control module 200 and detect the level state of this detection signal, when the level state detecting signal shuts down level for presetting, determine that described overhead door occurs abnormal, control depurator shutdown, thus realizing depurator automatic shutdown when overhead door occurs abnormal, depurator air outlet under open state is avoided to be blocked and increase noise, guarantee that the parts such as motor of depurator do not damage because overhead door is abnormal, it is thus possible to extend the service life of depurator.
Specifically, described position detecting module 100 specifically for:
When depurator start runs, after a Preset Time, the state of detection depurator overhead door；When detecting that described overhead door is in abnormality, output level state is preset the detection signal of shutdown level；When detecting that described overhead door is in normal condition, output level state is preset the detection signal of start level.
When just starting shooting due to depurator, the blower fan of depurator has been turned on, and now overhead door should be at complete raised configuration under normal circumstances, now by the state of detection overhead door, it can be determined that whether overhead door exception occurs.In the present embodiment, position detecting module 100, when depurator start runs, detects the state of overhead door again after Preset Time, it is able to ensure that overhead door is in normal condition, namely overhead door is in complete raised configuration, is located higher than above-mentioned predeterminated position, it is to avoid the state of erroneous judgement overhead door.In actual applications, can be set in depurator start after Preset Time open blower fan so that overhead door rise completely after air-out eloquence air-out.
Above-mentioned Preset Time can according to the speed of service of overhead door and travel settings, this Preset Time is preferably set for the time needed for rising to extreme higher position more than or equal to overhead door from extreme lower position, such as overhead door rise to extreme higher position from extreme lower position needed for time be 30s, after 30s started shooting by depurator, then detect the state of overhead door again, to guarantee when starting the state detecting overhead door, overhead door, already at complete raised configuration, is located higher than above-mentioned predeterminated position, it is ensured that testing result is accurate.
In the state procedure of detection depurator overhead door, the state of the depurator overhead door detected should be normal condition or abnormality, therefore when detecting the state of depurator overhead door, it is judged that whether overhead door is in abnormality.When detecting that overhead door is in abnormality, fault as own in overhead door and be constantly in closed mode, position is lower than above-mentioned predeterminated position, the air outlet of depurator is blocked, or overhead door is pressed under being forced and is decreased below above-mentioned predeterminated position, when blocking the air outlet of depurator, the level state of the detection signal of position detecting module 100 output is for presetting shutdown level.On the contrary, when detecting that overhead door is in normal condition, namely overhead door is already at complete raised configuration, is located higher than above-mentioned predeterminated position, when making the normal air-out of the air outlet of depurator, the level state of the detection signal of position detecting module 100 output is for presetting start level.
Specifically, described switching on and shutting down control module 200 specifically for:
Detect the level state of described detection signal；When the level state described detection signal being detected is preset shutdown level always, it is determined that described overhead door is constantly in closed mode, controls depurator shutdown；When the level state described detection signal being detected is become presetting shutdown level from presetting start level, and when being not detected by shutdown command, it is determined that described overhead door is in and is forced pressed status, controls depurator shutdown.
After position detecting module 100 detects state the output corresponding detection signal of overhead door, switching on and shutting down control module 200 and receive this detection signal, and detect the level state of this detection signal, determine the state of overhead door with the level state according to this detection signal for presetting start level or default shutdown level, and then judge that overhead door is in normal condition or abnormality.
When running due to depurator start, if overhead door is in normal condition, then the level state of described detection signal is for presetting start level.Therefore; in the level state process detecting described detection signal; if shutdown controls module 200 detects that the level state of described detection signal is always for presetting shutdown level; then illustrate that overhead door is constantly in lower than above-mentioned predeterminated position; the perfect condition that now should be at being higher than above-mentioned predeterminated position with overhead door is not inconsistent; thus it is abnormal to judge that overhead door occurs, now shutdown controls module 200 and controls depurator shutdown, makes depurator automatic shutdown enter guard mode.
In like manner, in the level state process detecting described detection signal, if shutdown controls module 200 detects that the level state of described detection signal is from the situation presetting start level and become presetting shutdown level, then illustrate that overhead door is decreased below predeterminated position from higher than predeterminated position, namely overhead door becomes closed mode from raised configuration, if being now not detected by shutdown command, then illustrate that overhead door is not that depurator to shut down and to decline, now it is judged as that elevator is pressed under being forced and declined, thus it is abnormal to judge that overhead door occurs, now shutdown controls module 200 and controls depurator shutdown, depurator automatic shutdown is made to enter guard mode.
With reference to the structural representation that Fig. 6, Fig. 6 are depurator another embodiment of automaton of the present invention.
With the depurator automaton shown in Fig. 5 the difference is that, as shown in Figure 6, the depurator automaton of the present invention also includes elevating control module 300, this elevating control module 300 is for when start-up command being detected, control described overhead door to rise, make described overhead door be in complete raised configuration.
When pressing under overhead door is forced, if overhead door does not drop to extreme lower position, namely overhead door does not run a complete stroke, then when depurator causes start because overhead door is forced to press down after automatic shutdown, overhead door will rise less than extreme higher position, be not in complete raised configuration.Such as, the rise stroke of overhead door is to run 150 degree clockwise under normal circumstances, then after overhead door rises, if the situation of normal shutdown, then overhead door needs to run 150 degree counterclockwise, and overhead door just can be made in the completely closed state；If overhead door is down pressed by external force, and make the situation of depurator automatic shutdown, if overhead door has only run 20 degree counterclockwise when depurator shuts down, if now detecting, start-up command after-purification device is started shooting at once, owing to when depurator shuts down, overhead door has only run 20 degree counterclockwise, therefore, when depurator is started shooting again, overhead door only runs 20 degree clockwise, namely think that overhead door is already at complete raised configuration, but actually now overhead door does not rise completely.
Thus, during for preventing depurator from again starting shooting after automatic shutdown because overhead door is forced to press down, start shooting immediately after start-up command being detected, then there is no complete raised configuration owing to overhead door is in, and cause the misjudgment phenomenon to overhead door state, in the present embodiment, abnormal detecting that overhead door occurs, after depurator automatic shutdown, if start-up command being detected by elevating control module 300, then need first to control overhead door to rise, described overhead door is made to run a complete upward stroke, overhead door is made again to reset, it is in complete raised configuration, control module 200 again through switching on and shutting down and control depurator starting up's fan operation, guarantee the normal air-out of air outlet of depurator, guarantee that depurator normally can stably run and not damage because of overhead door fault.
The present invention also provides for a kind of depurator further, and this depurator includes above-mentioned depurator automaton, and structure that this depurator automatically controls dress and the beneficial effect that brings, all with reference to above-described embodiment, repeat no more herein.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
