Abstract
The invention discloses a projector and a control method of the running state of a cooling fan of the projector and is characterized in that temperature of essential parts in heat dissipation areas inside a case is detected, the corresponding cooling fan starts to run or keeps running when the detected temperature is higher than or equal to the given temperature while the corresponding cooling fan stops running when the detected temperature is lower than the given temperature. By detecting the temperature of selected corresponding essential parts inside the case of the projector, the control method of the invention controls the running states of corresponding cooling fans, optimizes the running time of the fans, ensures the service life of the machine, saves the energy and reduces the consumption at the same time.
Description
Technical field
The present invention relates generally to projector, also relates to the control method of projector heat radiation fan running status.
Background technology
Present most of projector----light source generally all adopts ultrahigh pressure mercury lamp.The heat of lamp own is higher, for life-span and the reliability that guarantees the machine intimate parts, needs to allow the case radiation fan work a period of time after shutdown again.Unused time is generally fixed, can not change because of the temperature conditions in the machine, so sometimes in the machine temperature still higher, but, influence service life of a machine because the heat radiation time is out of service and stop to dispel the heat to radiator fan; Sometimes machine belongs to of short duration start back shutdown, need not long-time heat radiation, and under this type of situation, radiator fan is delay working still, easily causes energy dissipation.
Summary of the invention
The invention of this group mainly is to solve the above-mentioned technological deficiency that the projector heat radiation fan operation control method is brought in the prior art, one of its task is to provide a kind of projector, two of its task is to provide the control method of projector heat radiation fan running status, and these technical measures can make the interior at random temperature variation of the running status of projector heat radiation fan and change.
For realizing task one of the present invention, its technical solution is:
A kind of projector, comprise at least one radiator fan, above-mentioned projector also comprises central controller and at least one hygrosensor, the said temperature detector is placed on the critical component heat release zone of projector, and link to each other with central controller, central controller is controlled corresponding radiator fan according to the temperature information that hygrosensor collects.
Above-mentioned central controller can be by a pwm pulse signal control of output radiator fan.
Above-mentioned central controller can be controlled the shutdown of described projector when all fans are out of service.
Above-mentioned critical component can comprise display chip, light source and circuit board.
For realizing task two of the present invention, its technical solution is:
A kind of control method of projector heat radiation fan running status comprises step:
The Current Temperatures at least one critical component heat release zone in a, the detection cabinet;
B, described Current Temperatures and a predefined temperature are made comparisons;
C, when Current Temperatures is greater than or equal to preset temperature:
C1, indication radiator fan bring into operation or keep operation;
D, when Current Temperatures is lower than preset temperature:
D1, the indication radiator fan out of service.
In the above-mentioned control method, its step c also comprises step:
Behind c2, the delay certain hour, repeating step a.
In the above-mentioned control method, its steps d also comprises step:
D2, the shutdown of the described projector of indication.
For realizing task two of the present invention, its technical solution is:
A kind of control method of projector heat radiation fan running status comprises step:
The Current Temperatures at least two parts heat release zones is labeled as first Current Temperatures and second Current Temperatures respectively in a, the detection cabinet;
B, first Current Temperatures and predefined first preset temperature are made comparisons, when first Current Temperatures is greater than or equal to first preset temperature:
B1, the first corresponding radiator fan of indication bring into operation or keep operation;
When first Current Temperatures is lower than first preset temperature:
First radiator fan of b2, indication correspondence is out of service;
C, second Current Temperatures and predefined second preset temperature are made comparisons, when second Current Temperatures is greater than or equal to second preset temperature:
C1, the second corresponding radiator fan of indication bring into operation or keep operation;
When second Current Temperatures is lower than second preset temperature:
Second radiator fan of c2, indication correspondence is out of service.
Also comprise step in the above-mentioned control method:
Behind d, the delay certain hour, repeating step a.
Also comprise step in the above-mentioned control method:
E, after all radiator fans all quit work, indicate the shutdown of described projector.
The invention of this group, by temp probe is set near the cabinet inside critical component this critical component heat release zone temperature information is detected in real time, by circuit and corresponding software control, allow corresponding radiator fan be in operation or run-stopping status with temperature conditions.The i.e. temperature of the relevant selected critical component of cabinet inside by detecting projector etc. is controlled running status of each relevant radiator fan, can optimize the working time of the aft-fan that shuts down, and in the assurance service life of a machine, can save energy again.
