First, the
In particular, the
Here, the environmental sensor 111 measures temperature, humidity, illuminance, electromagnetic wave, vibration, noise, etc. of the room or the vehicle.
A sensor for measuring various environments as described above is separately provided.
At this time, a temperature sensor for measuring the temperature of a room or a vehicle is widely used throughout the industry. For example, it is used not only for temperature control in home appliances such as air conditioners and refrigerators, but also in precision industries such as the semiconductor industry.
The current thermometer is classified according to the measurement principle as follows.
First, there is a thermometer using thermal expansion. There are gas thermometers and liquid thermometers bimetal thermometers. Among them, the liquid thermometer has a thermometer using mercury or kerosene. In the past, the red thermometer was mostly an alcohol thermometer (using alcohol with red paint), but because of condensation in the upper part of the liquid, it could lead to errors in the instructions, so they used kerosene for 30 years . Domestic thermometer and thermometer are also one of these liquid thermometers. There is also the highest and lowest thermometer · Beckman thermometer using this liquid thermometer. The bimetal thermometer uses two types of metal plates with different expansion coefficients, namely bimetal, in which two thin plates of copper and nickel are in close contact with each other. In this bimetallic thermometer, the expansion coefficient of copper is larger than that of nickel, so when it gets hot, it bends toward the nickel plate. When the temperature becomes low, the temperature is displayed using the principle of bending toward the copper plate.
Next, there is a thermoresistive thermometer using the temperature change of electrical resistance. This is a resistance thermometer, which is based on the fact that the electrical resistance of metals and semiconductors has temperature dependence.
A thermocouple thermometer connects two different types of metal or alloy wires to form a looped circuit that conducts electricity. When a temperature difference is applied to both ends of the contact, the thermoelectric power is generated at both ends of the contact so that a current flows. This is called the Peltier effect (thermoelectric effect), and the thermometer used is the thermocouple thermometer. The measurement of the generated thermoelectric power is measured by a potentiometer or a millivolt system with a large internal resistance, and is most widely used for temperature measurement in the temperature-thermoelectric power calibration. The reason for this is that the volume of the metal joint portion, which is the sensing portion, is very small, so that the tolerance according to the heat capacity is small and the response to heat is excellent. Thermocouples used include platinum wire, platinum-rhodium alloy wire, copper wire and constant wire.
There is a color thermometer according to the light. These include optical pyrometers (also called optical pyrometers) and radiation pyrometers.
The optical pyrometer is a method of obtaining the color temperature by comparing the color temperature of the measuring object with the standard color temperature, which can be measured to about 700 to 2500 ° C. The radiation pyrometer measures the temperature based on the change in the resistance value due to the temperature rise of the thermistor by condensing the heat energy radiated from the object to be measured with a lens or a concave mirror and placing a thermistor (a resistor sensitive to the ambient temperature) at the focus. As one of the radiation pyrometers, there is a thermometer for thermography using a semiconductor thermosensitive element for infrared rays. Using this, we investigate the surface temperature distribution of the Earth and the skin temperature distribution in the human body.
There are also Ger-con thermometers and thermo-color thermometers. Gerkhorn thermometer is a triangular pyramid with a height of 10 cm, made of silicate and metal oxide. It is used to examine the temperature distribution in the furnace by examining the degree of melting of the triangular pyramid by arranging and heating each place in the furnace. Thermo-color thermometer is a thermometer that uses the principle that the thermochrome, also called Zion paint, changes color.
A thermometer using a phenomenon in which a complex salt such as cobalt and chromium reversibly changes color depending on the temperature. This material is called a thermoclay after being dried with clay. Recently, a liquid-crystal thermometer using the temperature characteristic of a liquid crystal (liquid crystal) as a thermo-color thermometer has been introduced
Among the various methods described above, a temperature sensor suitable for the use environment is applied.
In addition, the humidity sensor for measuring the temperature of the room or the vehicle detects the humidity and outputs it as an electrical signal. The humidity is measured by using the fact that the electrical resistance and the electric capacity of the porous ceramics and the polymer electrolyte change due to the physical adsorption of moisture, the change of the resonance frequency of the piezoelectric body, and the electrolysis of water.
The illuminance sensor for measuring the temperature of a room or a vehicle is a method for forming an electrode pattern on a substrate in the production of a substrate used for PDP (Plasma Display Panel), LCD (Liquid Crystal Display) A method in which a formed mask is projected and irradiated onto a substrate to which a photoresist is applied to form a pattern of the mask on the substrate is used.
The electromagnetic wave sensor for measuring the temperature of the room or the vehicle includes a coil for receiving electromagnetic waves generated from the information communication device and generating a fine current, a coil for converting the analog voltage into an analog voltage according to the intensity of the micro current generated by the coil, Of the resistance value. When the coil receives an electromagnetic wave generated from the information communication device, a minute current change is detected. The change of the detected current is converted into an analog voltage by the resistor of the electromagnetic wave sensing unit and output.
In addition, the vibration sensor for measuring the temperature of the room or the vehicle is an apparatus for detecting the acceleration by converting the mechanical energy of the force into electric energy. According to the method of converting mechanical energy into electrical energy, the acceleration detector is classified into a piezoelectric type, a servo type, and a torsional gauge type. Among them, the piezoelectric type is the most widely used method in an acceleration sensor.
The piezoelectric acceleration detector uses a piezoelectric effect in which electric energy is generated in proportion to the magnitude of the force when an external force is applied to the piezoelectric element located at the detection portion and deformation occurs. The main components of the piezoelectric acceleration sensor are a basic structure, an inertial mass, and a sensing piezoelectric element. There are roughly three types of piezoelectric elements depending on the generation method of the piezoelectric element located at the sensing portion.
At this time, when the force F is applied to the inertial mass M, the piezoelectric element P between the inertial mass M and the base structure B is compressed and deformed in the same direction as the polarization direction of the piezoelectric element. If the force F is applied to the weight M mounted through the piezoelectric element P, the shearing force is applied to the piezoelectric element P, and the shear force is applied to the same direction as the polarization direction of the piezoelectric element P. In addition, when the force F is applied to the weight M mounted on the tip of the piezoelectric element P, the one-sided support arm is twisted at right angles to the polarization axis direction of the piezoelectric element.
These various types of piezoelectric acceleration sensors are classified according to conditions such as frequency, acceleration amount, and measurement range. For example, a compression type and a shearing type are used for detection of a used frequency, and a one-side supporting type which can detect a minute vibration with higher detection sensitivity than these methods is used.
The noise sensor for measuring the temperature of the room or vehicle is constituted by a noise detection circuit for calculating the sound pressure value of the entire frequency band based on the voltage signal amplified by the microphone preamplifier. The noise detection circuit consists of an RMS detector that calculates the sound pressure value of the entire frequency band by detecting the root mean square (RMS) value of the input voltage signal, and compares the calculated sound pressure value with an appropriate unit, for example, dB.
To simplify the operation of the noise measurement apparatus, the noise generated in the measurement object in the non-directional room is input to the microphone, converted into a voltage signal according to the sound pressure, and then amplified by the microphone preamplifier. The voltage signal amplified by the microphone preamplifier is calculated as the sound pressure value of the entire frequency band in the noise detection circuit, and the value is converted into dB and displayed through the deflections section.
As a result, the
Further, the contamination sensor 113 measures the carbon dioxide, carbon monoxide, formaldehyde, asbestos, ambien, volatile organic compounds, fine dust, etc. of the room or the vehicle.
A pollution degree detecting circuit diagram of a general air cleaner includes a contamination detecting sensor including an exothermic heating coil to which 5 V is applied and a gas electrode on which tin oxide (SnO 2) is surface-treated, And the contamination detection signal is applied to the microcomputer through the connected resistors R1 and R2.
When the +5 V constant voltage is applied to the contamination detection sensor, the heating coil is heated to generate heat, and the heated heat is transmitted to the gas electrode so that the resistance between the gas electrode and the resistor R1 And the output voltage appearing between the resistor R2 and the ground is applied to the microcomputer so that the air pollution degree is detected.
That is, when the oxygen is adsorbed on tin oxide (SnO2) surface-treated on the gas electrode, the oxygen has an electron affinity, which interferes with the flow of free electrons in tin oxide (SnO2) Increases resistance.
When such a reducing gas (for example, hydrogen) is introduced into the sensor, oxidation reaction of the gas with adsorbed oxygen occurs on the surface of tin oxide (SnO 2). As a result, adsorption occurs on the surface of tin oxide The amount of oxygen contained in the air is reduced and the electrons are easily moved, and the concentration of the gas contained in the atmosphere can be detected by the resistance change by the principle that the electrical resistance is reduced.
Therefore, when the pollutant is generated, the voltage across the gas electrode is significantly reduced, and the voltage between both ends of the resistors R1 and R2 is relatively increased, so that the output voltage of the contamination detecting sensor 1 is converted into a digital signal And the blowing fan is controlled according to various conditions by comparing the value obtained by the conversion with preset data.
The conventional method of controlling the air cleaner using the pollution detection sensor will be described in detail with reference to FIG. 1B. First, the contamination state of the room is divided into three or more conditions, and according to the clean condition classified into the respective conditions, The voltage output from the sensor is input to the microcomputer in advance and stored.
For example, assuming that the output voltage of the contamination detection sensor 1 is 0.7 V when the room is clean, assuming that the room is contaminated to some extent and the air purifier needs to be driven, the output voltage is 1 V, .
In this state, when the air purifier is supplied with power and is operated in the automatic operation mode, the microcomputer reads the output voltage Vo of the contamination detection sensor after warming up for about 3 minutes. The output voltage (Vo) is 0.7 V or less, it is judged as a clean state.
Particularly, sensors for measuring fine dust use an air quality mass measuring device using a beta ray absorption method, a moving type electric mobility classification device, an optical particle counter, and a vibration correction microbalance.
The fine dust detecting apparatus includes a MEMS sensor unit, a driving unit attached to the MEMS sensor unit to resonate the MEMS sensor unit, and a MEMS sensor unit that measures the mass density of the fine dust using the displacement of the MEMS sensor unit due to the fine dust adsorbed on the MEMS sensor unit. And an optical interferometer that can detect the light. The MEMS sensor part may include a MEMS structure and a suction electrode attached to the MEMS structure and generating an electrostatic force by an electric field supplied thereto. At this time, the end of the adsorption electrode may be connected to a power supply unit capable of applying an electric field to the adsorption electrode.
The MEMS structure may be formed in the shape of a cantilever, a bridge, a slope bridge or a thin film. The MEMS structure can be displaced by changing the shape by the mass of the adsorbed fine dust.
As a result, the
In addition, the travel sensor 115 measures the acceleration, the distance, and the fuel consumption of the vehicle.
As described above, a sensor for measuring various running situations is separately provided.
First, an acceleration sensor, which is generally used to measure acceleration, is a method of measuring displacement of a system made up of a spring and a mass called a size model system. When the angular frequency to be measured is lower than the natural angular frequency of the mass part, the displacement of the mass part almost corresponds to the acceleration. As this type of acceleration sensor, there are movable coil type, piezoelectric type, capacitive type, strain gauge type, servo type, and differential trans type.
As a result, the
