The present invention relates to an apparatus for recognizing a fuel in a vehicle between a lubricator used at a gas station and a fuel inlet of an automobile.

The fuels used in automobiles are expected to be used not only for gasoline, but also for hydrogen, oxygen, and methanol due to diesel, LPG and more environmentally friendly issues.

In the current situation where only diesel and gasoline are being used, as the diesel of passenger cars is being used, disputes, financial and time loss continue to occur due to problems such as gasoline filling of diesel cars by driver and gasoline mistake.

As a conventional technique, there is a domestic registered utility model No. 0380898, 'Oil detection device'. This technology is equipped with an oil sensor that detects the type of oil with the smell of oil on the gas gun, and the sensor detects the fuel type of the car's oil tank in advance. It is a device that sounds an alarm automatically.

Korean Patent Publication No. 10-2006-0023658 'Diesel fuel injection port' is a resilient white paper that supports the conical shape of the cap and the lower outer surface of the cap at the inlet of the diesel vehicle so as to be elastically rotatable in the filling pipe, It characterized in that it consists of a locking projection protruding on the lower outer surface of the cap to correspond to the gas oil.

Domestic Patent Publication No. 10-2006-0023280 'Diesel fuel refueling device for diesel vehicles' installs a number of contact sensor means in the filling port and detects the difference in diameter between gasoline fuel tanker and diesel fuel tanker, thereby making mistakes of gas stations. By injecting gasoline fuel into a low-diesel vehicle, it is possible to prevent serious damage to the vehicle.

Domestic Patent Publication No. 10-2005-0022521 'Auto fuel fractionation system' is installed in the fuel system of the vehicle pressure sensor for measuring the pressure by using the density of gasoline and diesel, the signal of the pressure sensor received The control unit judges whether or not the valve means installed in the fuel discharge line is operated by comparing with the preset pressure value of the fuel. At this time, if the pressure value is determined to be suitable fuel by matching the reference value, the valve means is opened to supply fuel. And, when it is determined that the fuel is not suitable other fuels inconsistent with the range of the input value, shuts off the valve means and lights a warning light so that the driver can recognize the fuel.

However, the above inventions all require the structural change of the fuel inlet of the vehicle except for the domestic registered utility model No. 0380898, 'Oil detection device', thereby including problems that the vehicle company should adopt the invention.

Domestic Patent Publication No. 10-2006-0023658 'Diesel fuel injection port' and Domestic Patent Publication No. 10-2006-0023280 'Diesel fuel prevention device for diesel vehicles' Discrimination is performed. However, this is only true for domestic cars, cars currently imported from Europe such as Mercedes-Benz, Audi, and Volkswagen are mainly in the situation that the gas is not as small as gasoline. For this reason, because gas stations are similar, gas station employees often use gasoline instead of diesel.

Domestic registered utility model No. 0397671, 'Vehicle mixing prevention alarm device' is equipped with an alarm device at the fuel inlet and driver's side of a car or taxi, and sends a mixture prevention message for diesel and gasoline to send fuel injection appropriate to the vehicle. The present invention relates to a vehicle anti-mixing warning device for guiding the user to be without confusion. However, since the user relies on the announcement, there is no device for detecting diesel or gasoline, so if the user does not hear or recognize the announcement, there is no blocking device even if other oil is in the vehicle. There is a problem.

In addition, the above inventions all focus on the determination of gasoline and diesel. Due to the increased awareness of environmental issues in parallel with the recent high oil price era, various fuels such as hydrogen, oxygen, and methanol, as well as gasoline and diesel, will be used for vehicle fuel. As various fuels are used in the future, problems related to oil discrimination will gradually increase in various forms.

The present invention is to solve the above problems, after determining whether the fuel injected from the vehicle fuel inlet and the fuel gun and the fuel inlet is a fuel that is compatible with each other after the refueling is not made automatically and a warning means expressed by sound It is an object of the present invention to provide a device having a characteristic of generating.

The present invention to solve the above problems,

Equipped with a wireless communication device 11, an oil filling hole closing unit 12, a control unit 13, a fuel information memory 14, or provided only with a wireless communication device 11, located around the gas filling port 40 An identification device (10) by means of radio;

When vehicle fuel information is transmitted to the radio communication apparatus 21 of the radio means discrimination apparatus 20 by the radio communication 30 to the radio communication apparatus 11 of the identification apparatus 10 by radio means, radio means discrimination is carried out. The control unit 13 of the device 10 recognizes whether the fuel is suitable for the vehicle by referring to the vehicle fuel information and the fuel information of the lubricator, and controls the fuel valve 24 to allow or block fueling and to generate a sound. We will provide a fuel recognition device that tells whether or not to determine through.

When the fuel oil proximity check unit 22 of the discriminating device 20 confirms the proximity of the vehicle filling port and sends a signal to the control unit 23 of the determining device 20, the control unit 23 controls the wireless communication device 21. The vehicle fuel information request signal is transmitted to the radio 30 to the radio communication device 11 of the vehicle identification device 10, and the radio communication device 11 of the vehicle identification device 10 receives the signal. When sent to the control unit 13, the control unit 13 reads the fuel information of the vehicle from the fuel information memory 14, and sends the fuel information of the vehicle to the radio 30 through the radio communication device (11). When the wireless communication device 21 of the determination device 20 receives the vehicle fuel signal and sends the vehicle fuel signal to the controller 23, the controller 23 recognizes whether the fuel is suitable for the vehicle by referring to the fuel information of the vehicle and the fuel information of the lubricator. By controlling the fuel valve 24, the fuel supply is allowed or blocked, and the sound generator 25 informs whether or not the discrepancy is determined. The sound that can be generated by the sound generator may be applied in various ways, such as a warning sound and voice guidance.

Since the radio communication device 11 of the identification device 10 communicates with the radio communication device 21 of the discriminating device 20 of the lubricator by radio 30, the radio communication device 11 may be positioned around the lubrication port 40. In FIG. 2, the gas supply gun 50 of the fuel tanker is shown, and the wireless communication device 21 of the determination device 20 is also located at the upper end of the fuel port of the fuel tank 50. However, the wireless communication device 21 of the determination device 20 is not necessarily limited to this position. In addition, the wireless communication device 21 of the determination device 20 is not necessarily located in the main fuel tank 50.
