Description
Technical field
The present invention relates to field of household appliance control, particularly relate to a kind of electric blanket energy-saving control method based on pressure sensitive.
Background technology
Electric blanket, has another name called electrical blanket, and be a kind of contact electric heating appliance, it is by special, and the soft cable-styled heating that insulating property reach standard inweaves or sews up in dish serpentine in woollen blanket, during energising and the evolution of heat.Be mainly used in improving when people sleep temperature in quilt to reach heating object.What also can be used for bed clothes goes tide dehumidifying.Its power consumption is few, temperature is adjustable, easy to use, use is extensive, the history of existing more than 100 year.Had at present Novel non radiation electric blanket to obtain national patent, pregnant woman, children, old man can relieved use Nonradiative electric blanket.
Along with the development of science and technology, the application of sensor is increasingly extensive, sensor substitutes people and obtains various information, the ultimate principle of multi-sensor information fusion technology is just as the process of the brain overall treatment information of people, various sensor is carried out message complementary sense and the optimal combination process in multi-level, many spaces, final generation is explained the consistance of observing environment.Multi-source data will be utilized in this process fully to carry out rationally domination and use, and the final goal of information fusion is then the separation observation information obtained based on each sensor, derives more useful informations by, various combinations multi-level to information.This is not only and make use of the mutual crew-served advantage of multiple sensor, and the data in overall treatment out of Memory source improve the intellectuality of whole sensing system.
Pressure transducer is the most widely used a kind of sensor.Traditional pressure transducer is based on the device of physical construction type, and with the deformation indicated pressure of flexible member, but this physical dimension is large, quality weight, and electricity can not be provided to export.Along with the development of semiconductor technology, semiconductor pressure sensor also arises at the historic moment.Be characterized in that volume is little, quality is light, accuracy is high, good temp characteristic.Particularly along with the development of MEMS technology, semiconductor transducer is towards miniaturization, and its power consumption is little, reliability is high.
It is made up of parts such as matrix material, metal strain silk or strain paper tinsel, insulation protection sheet and extension lines.According to different purposes, the resistance of resistance strain gage can be designed by deviser, but the span of resistance should be noted: resistance is too little, required drive current is too large, the heating of foil gauge simultaneously causes the temperature of itself too high, uses, make the change in resistance of foil gauge too large in different environment, output zero point drift is obvious, and zeroing circuit is too complicated.And resistance is too large, impedance is too high, and the electromagnetic interference capability in the anti-external world is poor.About being generally tens Europe to tens kilo-ohm.
Resistance strain gage is a kind of Sensitive Apparatus strain variation on measured piece being converted into a kind of electric signal.It is one of chief component of pressure resistance type strain transducer.What resistance strain gage application was maximum is metal resistance strain gauge and semiconductor gauge two kinds.Metal resistance strain gauge has again thread foil gauge and metal foil-like foil gauge two kinds.Normally being bonded in closely by special bonding agent by foil gauge produces on mechanics strain matrix, when the stressed generation STRESS VARIATION of matrix, resistance strain gage also produces deformation together, and the resistance of foil gauge is changed, thus makes to be added in ohmically voltage and change.The change in resistance that this foil gauge produces when stressed is usually less, and general this foil gauge all forms strain bridge, and is amplified by follow-up instrument amplifier, then is transferred to treatment circuit (normally A/D conversion and CPU) display or topworks.
The principle of work of metal resistance strain gauge is adsorbed on strain resistor on matrix material to produce the phenomenon of change in resistance with mechanical deformation, is commonly called as resistance strain effect.The resistance value R of metallic conductor can be represented by the formula:
R=ρL/S
In formula, ρ is the resistivity of metallic conductor, and S is the sectional area of conductor, and L is the length of conductor.
We are for tinsel strain resistor, when tinsel is by External Force Acting, its length and sectional area all can change, can be easy to find out from above formula, namely its resistance value can change, if when tinsel extends by External Force Acting, its length increases, and sectional area reduces, resistance value just can increase.When tinsel compresses by External Force Acting, length reduces and cross section increases, and resistance value then can reduce.As long as measure the change (normally the voltage at measuring resistance two ends) being added in resistance, strain strain feelings wiry can be obtained.
Should be noted that a lot of problem when selection pressure sensor, such as, the temperature characterisitic of the range of pressure transducer, precision, pressure transducer, chemical characteristic all will be considered, and the operating type of pressure transducer is also the major issue needing to consider.
Such as, when sensor is used for measurement from fluid pressure of the measurement of gaseous tension, situation is just different.Gas is compressible fluid, increases when taking by force and can store certain compression energy, discharge again during decompression with kinetic energy, apply shock wave to sensor elastic membrane.Require that pressure transducer has larger overload capacity.Liquid is incompressible fluid, when pressure transducer is installed, tightens nut and fluid pressure then can be made to increase to over the withstand voltage limit of elastic membrane without compressible space again, cause elastic membrane to be broken.Because this situation occurs repeatedly, also require that pressure transducer has larger overvoltage capabilities.During the work under bad environment of pressure transducer, such as, there are large vibration, impact, large electromagnetic interference (EMI), more strict requirement is proposed to sensor.Not only overvoltage capabilities is strong, and requires that mechanical seal is reliable, and anti-loosening, sensor is installed correct.The lead-in wire of sensor self, pin and outer conductor all should electromagnetic screens in addition, and will shield good earth.In addition, the consistency problem of pressure transducer and fluid being measured medium should be considered.The elastic membrane structure of such as sensor should separate with Korrosionsmedium, has now adopted stainless steel radiation fins sensor, and pressure transmitting medium made by the interior silicone oil of sensor.When sensor detects inflammable, explosive pressure medium, use little exciting current, produce spark, Mars when preventing elastic membrane from breaking, and increase the voltage endurance capability of pressure transducer overcoat.
Existing electric blanket is the on-line operation when being energized generally, and do not judge whether have people above it, sometimes, people can forget the plug pulling out electric blanket, on the one hand, cause the long-time dry run of electric blanket, waste electric energy, on the other hand, be subject to fire, potential safety hazard is very big.
In addition, existing electric blanket is all generally the heating of full blanket, but on heating blanket, the area of human body parts is general quite limited, and all the other do not have the heating of human body parts to be unnecessary to a great extent, belong to idle running, waste electric energy.
