Description
Technical field
The utility model relates to television set, especially a kind of moistureproof TV.
Background technology
TV has been indispensable household electrical appliance, and nowadays TV is more existed by as the one decoration inside house, seldom goes to use television set TV.At the environment of humidity, TV is infrequently energized work, and TV can make moist gradually, and the life-span of TV also can shorten.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of moistureproof TV.
The technical solution adopted in the utility model is:
A kind of moistureproof TV, comprise the humidity sensor, a timer, a single-chip microcomputer, the machine core board that are electrically connected successively, this humidity sensor is for detecting the humidity of environment residing for television set and exporting induced signal to timer according to humidity value change, timer triggers by this induced signal and exports induction frequencies signal to single-chip microcomputer, and Single-chip Controlling pin output level works with starter motor central layer.
Further, it also comprises the power supply main valve, power amplifier module, the backlight module that are electrically connected with machine core board.
Further, it also comprises a remote controller, and is arranged on the moistureproof button on this remote controller, and this moistureproof button is for sending moistureproof mode signal or exiting moistureproof mode signal to machine core board.
Further, described humidity sensor is HS1100 humicap, and timer is LMC555CH timer, is connected with electric capacity C between the pin of HS1100 humicap and LMC555CH timer, resistance R1, R2, R4, the output contact resistance R3 of LMC555CH timer is to single-chip microcomputer.
The beneficial effects of the utility model:
The moistureproof TV of the utility model is by arranging humidity sensor and 555 timers, and when inside television environment moisturizes, television set enters potential mode of operation, heat radiation makes environment desiccation, make electronic device be in dry environment, inside television circuit keeps away from moisture, and extends the useful life of TV.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the theory diagram of the moistureproof TV of the utility model;
Fig. 2 is the circuit diagram of humidity sensor and 555 timers;
Fig. 3 is the circuit diagram of single-chip microcomputer.
Embodiment
With reference to shown in Fig. 1, for the moistureproof TV of one of the present utility model, comprise the humidity sensor be electrically connected successively, one timer, one single-chip microcomputer, one machine core board, and the power supply main valve to be electrically connected with machine core board, power amplifier module, backlight module, this humidity sensor is for detecting the humidity of environment residing for television set and exporting induced signal to timer according to humidity value change, timer triggers by this induced signal and exports induction frequencies signal to single-chip microcomputer, Single-chip Controlling pin output level is with starter motor central layer, power supply main valve, power amplifier module, the work of backlight module.
As the further optimization of this programme, on the basis that above-mentioned humidity sensor is responded to automatically, an also auxiliary manual control program, namely one remote controller is set, and the moistureproof button be arranged on this remote controller, this moistureproof button is for sending moistureproof mode signal or exiting moistureproof mode signal to machine core board.
As Fig. 2, described humidity sensor is HS1100 humicap, and timer is LMC555CH timer, is connected with electric capacity C between the pin of HS1100 humicap and LMC555CH timer, resistance R1, R2, R4, the output contact resistance R3 of LMC555CH timer is to single-chip microcomputer.
The operation principle of this programme and process are cause the change of HS1100/1101 capacitance when ambient humidity changes, thus change the output frequency value in loop.As in Fig. 2 circuit, the capacitance of humidity sensor HS1100 must change the output frequency value causing 555 timer circuits, the value that out exports is connected on 51 series monolithic P3.5 pins, single-chip microcomputer inside programming, control pin output level (as Fig. 3), three port PWR-ON/OFF(machine core boards on controller central layer to be powered main valve), the mute signal of AMP-MUTE(power amplifier module), the control of ADJ/DIM(LED backlight module), realize potential mode of operation, reach the function of TV protection against the tide.
Just belong to moist when envionmental humidity reaches 80%, so when relative humidity reaches 75% in television set, feed high level to port PWR-ON/OFF, AMP-MUTE input high level, ADJ/DIM input low level, TV enters potential mode of operation; When inside television relative humidity lower than 75% time, PWR-ON/OFF input low level, just finishes the potential mode of operation of television set.
Potential mode of operation: each circuit of television set normally works, and television screen does not work, and television set speaker is quiet, and indicator light is in yellow.
In time entering potential mode of operation, indicator light is in yellow, wants to see TV when now, can by " protection against the tide " button on remote controller, and chip reset, exits moistureproof pattern.
The moistureproof TV of the utility model is by arranging humidity sensor and 555 timers, and when inside television environment moisturizes, television set enters potential mode of operation, heat radiation makes environment desiccation, make electronic device be in dry environment, inside television circuit keeps away from moisture, and extends the useful life of TV.
The foregoing is only preferred embodiments of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection range of the present utility model.
