The fragrance may be applied to the interior of the vehicle by using such an effect, thereby being used for the purpose of preventing sleepiness of the driver.

In this case, the automatic injecting device is limited in that it can not enjoy various directional effects by only one incense being sprayed into the space where the automatic injecting device is installed. In addition, As the spraying method is sprayed in the discharge direction of the nozzle in spraying the fragrance agent, the fragrance is strongly exposed only to a specific part, and the diffusion of the exposed fragrance is dependent on the convection phenomenon of the space, .

In addition, the automatic injecting apparatus is designed to discharge a predetermined amount of fragrance from the container at a predetermined time unit, and even if the user does not stay in the space, directional compounds may be unnecessarily consumed.

To overcome these limitations, Korean Patent Laid-Open No. 2005-0032232 entitled " Vehicle automatic direction device and method thereof " is published. The prior art discloses an automatic direction device and method for a vehicle.

The above-described technology is implemented to enable various directional effects to be enjoyed by incorporating various kinds of fragrances injected selectively as needed, and to be controlled to be turned on only when necessary, thereby preventing unnecessary consumption. However, There is a possibility that the effect of the fragrance is not stably provided to the driver depending on the installation position of the perfume injection driver.

Further, it is described that the state of the driver can not be effectively controlled due to the low probability of the bar blood pressure being formed for sensing the blood pressure and injecting the specific fragrance based on the blood pressure and the driver's condition, and the blood pressure sensor used in the treadmill handle is used as it is It is unclear whether it is practically applicable.

Korean Patent No. 0536526 'Vehicle Incense Injection Apparatus' is composed of a self-direction injection switch, an ABS operation sensing unit which converts it into a certain electric signal when ABS is operated, a TCS operation detection unit which converts it into a certain electric signal during TCS operation, An ECS operation detecting unit for converting the ECS operation signal into a predetermined electrical signal during ECS operation, and an ECS operation detecting unit for converting the ECS operation signal into a constant electric signal when the ECS operation is performed, A control section for stopping the fragrance injection and outputting a control signal so as to inject aroma fragrance when the ECS or the emergency light is operated; a fragrance spraying section for stopping the spraying of the fragrance by the output signal of the control section; Aroma fragrance spraying is performed by the aroma incense sprayer, and when the emergency situation occurs, stop spraying the fragrance And the aroma incense is automatically sprayed so as to help the driver and the passenger to be psychologically stabilized.

The above-mentioned prior patents recognize only the operating states of various configurations of the vehicle including the ABS, the TCS, the ECS or the emergency light, and there is no parameter that can grasp the actual driver's condition. Therefore, there is no room for control in the case of driving the driver in the drowsy operation, and the configuration for effective diffusion of the fragrance is not provided.

Accordingly, it is possible to directly and clearly understand the states of the examinees and workers sitting at the driver or the desk in the vehicle, and to provide a specific incense based on this, thereby enhancing concentration and preventing drowsiness. It is necessary to develop a new and advanced intelligent direction system that efficiently diffuses the fragrance to deliver the effect of fragrance to the user more efficiently and double the efficacy.

The vaporized fragrance is diffused to the outside through the ventilation hole 241 along the airflow generated by the driving of the fan 243. At this time, depending on the angle formed by the fan 243 and the ventilation hole 241, But it is possible to obtain a desired effect more immediately by allowing the user to be exposed more directly to the fragrance. In addition, as the primary vaporization in the vaporization space 242, the liquid aromatic agent is directly discharged to the outside of the housing, so that it is prevented from directly touching the surface of the user's skin or the structure of the vehicle.

Referring to FIG. 1 again, the detailed configuration and operation of the state information generating apparatus 100 for transmitting various information to the controller 230 will be described. The state information generating apparatus 100 basically includes a smart band A lever cover 100b that covers one side of the surface of a gear shift lever or a steering device (steering wheel, steering wheel) of the vehicle that can be implemented as a handle 100a, As shown in FIG. The state information generating apparatus 100 includes a pressure sensor, a humidity sensor, a temperature sensor, and the like. The sensor 100 senses the user's heart rate, motion of the user, And transmits the generated information to the controller 230 of the perfume injection device 200.

When the state information generating apparatus 100 is implemented as the smart band 100a, the smart band 100a is formed in a shape similar to a wristwatch as shown in the figure, Respectively. The heart rate sensor is formed on a back surface of a clock-shaped circular ornament and senses a heartbeat of a user to generate heartbeat state information and transmits the generated heartbeat state information to the controller 230.

In addition, the smart band 100a may further include a pressure-sensitive motion sensor on a back surface of a portion of the band where the wrist inner tendon is formed, so as to generate activity information based on the pressure sensing applied by the movement of the tendon have. In other words, when the user moves his / her hand or arm to operate the steering wheel or the shift lever for driving, tendons and muscles passing through the inside of the wrist are inevitably moved. So that the user can grasp how active the hands or arms are.

The smart band 100a is applied to an in-vehicle driver. However, the user using the smart band 100a and the fragrance injection device 200 may be applied not only to a driver but also to an examinee or a worker sitting on a desk, , It can be used as a means to control stress and improve concentration in business.

When the state information generating apparatus 100 is formed of the lever cover 100b or the handle cover 100c described above, the lever cover 100b or the handle cover 100c may further include a grip sensor And a humidity sensor.

The grip sensor senses the pressure applied from the user's palm holding the lever or the handle for driving operation, and generates the grip state information. The grip sensor can be implemented as a pressure sensor. In addition, the humidity sensor senses the moisture contacted to the lever cover 100b and the handle cover 100c by sweat on the palm to generate sweat state information.

The various information generated by the above-described configuration is transmitted to the control unit 230 via the wireless communication means and serves as a basis for the selective driving of the jetting unit 222. For this purpose, And includes a drowsiness determination part and a stress determination part 231 as shown in FIG.

The drowsiness determination part 232 receives at least one of the activity state information and the grip state information and calculates an activity level based on a predetermined reference. If the activity level is less than a predetermined reference value, 210 to control the jetting unit 222 so that the awakening fragrance is sprayed from the one chamber 210 containing the awakening fragrance.

Described below is a process for calculating an activity level specified in numerical values from the activity status information. Basically, it is implemented in such a manner that a movement frequency of a hand or an arm is measured based on activity status information formed based on a movement of a hand or an arm It is also possible to determine the cause and type of the movement of the user on the basis of the predetermined activity pattern, and to calculate the activity based on this. Based on the grip state information, the degree of pressure or the frequency of depressurization can be grasped and utilized as an element in the calculation of the activity level. It is a matter of course that a known calculation method including a hierarchical analysis method may be applied to the method of calculating the activity using the activity state information and the grip state information. In addition, the activity level may be calculated using the electrocardiogram analysis method to be described later by receiving the heartbeat status information from the heartbeat sensor described above.

The stress determination part 231 receives the heartbeat status information from the heartbeat sensor, receives the sweat state information from the humidity sensor, and calculates the fatigue by analyzing the stress level of the user based on the received information. Since the principle of analyzing the stress level based on the electrocardiogram analyzed from the heartbeat state information is known through various documents published by the European Cardiac Society and the North American Heart Rate Electrophysiology Society, the data processing method of the stress determination part 231 May allow one or more of the various conventional approaches to be applied.

5 is a view illustrating an example of a fatigue determination process according to the present invention.

Referring to FIG. 5, the stress determination part 231 calculates the fatigue based on the heartbeat state information from the stress sensor 231, After receiving the state information, the heartbeat detection signal is amplified as shown in FIG. 6 (b), the amplified heartbeat detection signal is amplified as shown in FIG. 6 (c), the electrocardiogram signal is derived by second differentiation, Thereby detecting a peak point. 6 (d), the electrocardiogram determining part measures the interval between the PPs or RRs using the waveform capable of detecting the peak point, and calculates the RR data average interval, the standard deviation, the adjacent RR interval And the standard deviation is analyzed to estimate the stress and the fatigue is calculated.

The stress determination part 231 also uses the sweat state information to determine whether the humidity has increased in a large range from the average humidity based on the average humidity from the first time point at which the humidity is sensed by the user to the specific point in time, It is possible to deduce the tensions of fatigue and to use it as an element of fatigue calculation.

The fatigue may be calculated for each of the heartbeat state information and the sweat state information separately or in a summed manner.

The stress determination part 231 calculates the fatigue by determining the current stress state of the user by using the above-described method or the like, and when the fatigue becomes higher than a predetermined reference value, So that the calm fragrance agent can be injected by controlling the driving of the jetting section 222 connected to the chamber 210.
