One end of described motor is with gear, and a side of described Air Filter is slide bar, and the one side of described slide bar is tooth bar, and motor is receiving after Air Filter OPEN, and driven wheel rotates, and the motion of band moving slide-bar, opens Air Filter.
The electronic system that the embodiment of the present invention provides is by monitoring temperature, dust guard condition monitoring and business monitoring interlock.In embodiments of the present invention, temperature controller obtains the temperature value that temperature sensor detects, in the time that the temperature sensor of internal system detects that temperature exceedes predefined threshold temperature, controller determines that now Air Filter stops up, the Air Filter of controller control motor Unscrew dust screen apparatus, recovery system ventilates, the overheated risk of deactivation system, avoid the just unexpected interruption in operating business, also avoided the risk reducing at the temperature lifetime of system that operation brings higher than alarm threshold in the situation that for a long time due to system simultaneously.On the other hand, temperature controller sends temperature alarming message to service controller, and service controller guarantees just to carry out smoothly in operating business, and refusal Added Business, changes Air Filter immediately by the mode reminding user of this refusal new business.
As shown in Figure 6, the control method process flow diagram of the another kind of dust guard providing for the embodiment of the present invention, described method comprises:
Step 601: temperature sensor detected electrons internal system temperature, sends to temperature controller by the temperature value detecting.
Electronic system and system fan are in the time of normal operating conditions, because Air Filter needs the particle in filtered air, cause dust to be deposited in gradually in Air Filter, cause system ventilation amount to decline, system radiating ability declines, device temperature and temperature sensing actuator temperature rise gradually, but because not exceeding predefined notice thresholding and alarm threshold, system is in normal operating conditions.
Step 602: along with the accumulation of the particles such as dust, system radiating continues to worsen, temperature controller determines that according to the temperature value receiving electronic system internal temperature reaches predefined notice thresholding, and temperature controller is changed Air Filter in time by service controller reminding user.If user has changed Air Filter in time, whole system is recovered normal operation; Otherwise, carry out more than 603.
Step 604: temperature controller sends Air Filter OPEN to described motor, controls described motor and opens described Air Filter.Now Air Filter is opened, make system air intake without Air Filter, but enter system through in the breach of opening, because there is no the inhibition of Air Filter, the intake of system increases greatly, heat in system is taken away in a large number, and intrasystem temperature sharply declines, thereby reaches the object of eliminating system overheat risk.
Step 605: after Air Filter is opened, the temperature controller in system records the open mode of Air Filter, and sends warning information, reminding user need to be changed Air Filter immediately.If now Air Filter is changed, and obtain that Air Filter has been changed to instruction and send to temperature controller, temperature controller control motor cuts out Air Filter, and system reenters normal operating conditions.
If step 606. system Air Filter in step 605 is changed not yet, system continues to carry out periodicity alarm to user, and shows risk duty.Temperature controller suspends indication to described service controller transmission business, and described business is suspended indication and is used for notifying described service controller refusal to accept new business.This step, by controlling in business, does not allow new business to carry out, but guarantees that the business of having carried out proceeds, until Air Filter is changed.
Because system does not allow its device temperature to exceed its specification in working order, and device temperature all needs to feed back by temperature sensor, under certain duty, there is one-to-one relationship in temperature sensor and device temperature, understand this corresponding relation and just can understand the device temperature under this duty, because the temperature specification of device is clear and definite, can obtain thus the most responsive device of whole system under this duty and the temperature conditions of this device, notice thresholding and alarm threshold that accordingly can initialization system.Conventionally, notice temperature value corresponding to thresholding is less than the temperature value that alarm threshold is corresponding, and two temperature value corresponding to thresholding temperature sensor reading all should be less than in electronic system Sensitive Apparatus and reach its temperature specification time.
In step 601 and 602, fan can also carry out speed governing and delay the time that Air Filter dust stratification causes warning to start as far as possible.
Just start the application stage at Air Filter, because it does not pile up dust, therefore intrasystem temperature is in lower state, and now corresponding rotation speed of the fan is also lower.
Along with the accumulation of Air Filter dust, the lower temperature that the system that maintain is initial, just needing increases by the air quantity of system.Therefore, the rotating speed of fan can be divided into abundant gear, in the time that temperature sensor in system detects that system temperature increases, promote by the air quantity of system by the rotating speed gear that increases fan, thereby heat radiation ability is dealt with, because of the rotating speed gear of fan cut apart enough little, therefore, can the temperature of temperature sensor in system be controlled to the initial lower state of temperature of system within the regular hour.
Because of the requirement that system noise requires and the limit speed of fan own is set, the rotating speed of fan can not infinitely increase, therefore along with the lasting obstruction of Air Filter, carrying out the method for control system temperature rise in lower state by lifting rotation speed of the fan can arrive critical point in the some time, along with the rising of temperature will trigger the notice thresholding in step 602.
In above-mentioned steps 603, the object of notice thresholding is to make user before temperature reaches alarm threshold, change Air Filter, although initiate notification now, system now still can be thought safe operation state.Alarm threshold can be set in the risk critical point of system, once temperature reaches alarm threshold, Air Filter will be opened automatically, and system overheat risk can be removed.But now limit adding of new business, only maintain existing business and do not interrupt.By this kind of mode, can urge user to change in time Air Filter electric in the situation that system is lower.In addition, notice thresholding also can be set, in the time that system reaches alarm threshold, directly open Air Filter.
In above-mentioned steps 605, when temperature controller control motor is opened after Air Filter, the state that now temperature controller records Air Filter is for opening, if change Air Filter under this state, Air Filter is changed and is confirmed to realize in the following way: mode one, Air Filter can manual-lock, and after completing, the state of system log (SYSLOG) Air Filter, for closing, sends and changed Air Filter instruction to temperature controller; Mode two can arrange dialog box in system, in the time that system detection Air Filter open mode is long, ejects dialog box, inquiry user " your system equipment Air Filter is in open mode, and whether PLSCONFM has completed the replacing of Air Filter ".If confirmed, send and changed Air Filter instruction to temperature controller, notice temperature controller control motor cuts out Air Filter.If not, keep Air Filter open mode.
In above-mentioned steps 606, for preventing that user from still not changing Air Filter under the condition of business limited (not accepting new business), now Air Filter, for a long time in open mode, cannot be realized dust-proof effect.The operation that now can take is as follows: described temperature controller obtains current service condition from service controller, when described Air Filter opening time be greater than default maximum time and determine current without moving business time, control described motor and close Air Filter, send shutdown message to service controller, close described electronic system.
It should be noted that, the state of Air Filter and opening time can be recorded in the miscellaneous part of temperature controller or system, and the embodiment of the present invention does not limit this.
The electronic system that the embodiment of the present invention provides is by monitoring temperature, dust guard condition monitoring and business monitoring interlock.In embodiments of the present invention, temperature controller obtains the temperature value that temperature sensor detects, in the time that the temperature sensor of internal system detects that temperature exceedes predefined threshold temperature, controller determines that now Air Filter stops up, the Air Filter of controller control motor Unscrew dust screen apparatus, recovery system ventilates, the overheated risk of deactivation system, avoid the just unexpected interruption in operating business, also avoided the risk reducing at the temperature lifetime of system that operation brings higher than alarm threshold in the situation that for a long time due to system simultaneously.On the other hand, temperature controller sends temperature alarming message to service controller, service controller guarantees just to carry out smoothly in operating business, refusal Added Business, make temperature alarming can obtain effective attention of user by the mode of this refusal new business, reminding user is changed Air Filter immediately.Further, by recording Air Filter open mode and opening time, can follow the tracks of in time the state of Air Filter, avoid Air Filter to open for a long time the impact on damaging property of system.
