Description

Mobile Refueling System, Refueling Method, and Apparatus for Detecting Fuel Residual and Sending Detection Signal}

The present invention relates to a system for selling oil. More particularly, the present invention relates to a system and a fueling method for mobile oiling, and a fuel level meter and signal transmission device mounted to a fuel tank suitable for use in such a system and method.

In general, oil is mainly traded at gas stations, and in particular, gasoline is purchased entirely at gas stations. The driver checks the gasoline level through the fuel gauge while driving, and if the amount is not large, the motorist visits a gas station or gas station designated as a regular place to refuel. However, in the case of a driver who prefers a specific refinery or a particular gas station, there is a time when it is impossible to refuel in a timely manner. In particular, when these drivers are busy and are chased by schedules, they often feel nervous or embarrassed by refueling. On the other hand, when the driver neglects to check the remaining gasoline level, a situation may occur in which the remaining amount is impossible to operate the floor or the vehicle.

On the other hand, in the case of heating oil used in homes or business buildings or fuel used in factories, an oil delivery service is provided in which even oil visits a factory or home to refuel. However, the conventional oil delivery service is based on such an application when a person in charge of a factory or a building or a house resident checks the fuel level directly and makes an application by telephone. Thus, the conventional oil delivery service eliminates the hassle of having to visit a gas station or the person in charge of a factory or building to purchase a gas, but these people have to check the fuel level of the fuel tank from time to time. It does not let you avoid.

On the other hand, with the increase of vehicles, the number of gas stations also continues to increase, which generates harmful evaporative gases that not only discomfort to nearby residents, but also to fire insecurity for nearby residents or building owners. Will cause. In addition, due to fructose competition among refiners, refiners are making constant efforts to secure new gas stations and provide economic support for each new gas station. This phenomenon has aggravated the overall efficiency of society by deteriorating the balance of oil refiners or passing on to consumers. Thrown away. Therefore, it is possible to reduce the need for new gas stations and further reduce the number of existing gas stations.

As described above, in a preferred embodiment such a database 28 is such that the ADO object 24 is managed through the ODBC protocol 26. However, in another embodiment of the present invention, the database 28 may be linked to the application program 18 by other interlocking means such as JDBC.

Referring to FIG. 3, the member DB 31 stores a user name (ID), a password, and other personal information assigned by the system to each registered member. In a preferred embodiment, the cost according to the fueling service is settled through the member credit card. For this purpose, the member DB 51 stores the card number and password of each member. In addition, a mileage point field is provided to grant additional benefits according to the frequency of use and the cumulative purchase amount. On the other hand, it may be collected by subtracting the cost according to the fueling service from the deposit in advance, in this case, the deposit balance data of each member is stored in the member DB (31).

The oil even DB 32 stores a vehicle number, a loading type and capacity for each oil 70, a driver's name, address, a mobile phone number, and other communication terminal numbers such as a PDA, and the host 10 With this data it is possible to send a fueling command message to each oil 70 and the host 10 operator can even contact each driver. The inventory DB 33 stores data on the inventory of each oil type currently owned by the reservoir or even the oil of the host operator.

The visitor record DB 38 includes fields such as a serial number, a visitor's name, a visit date, and a message left for each post.

4 shows an embodiment of the fuel amount reading and signal transmission device 52 mounted on the vehicle. In a preferred embodiment, the fuel level reading and signal transmission device 52 includes a fuel level detection sensor 55, a microcontroller 56, a GPS receiver 57, a modulator 58 and a transmitter 59.

The fuel amount detection sensor 55 detects the amount of fuel remaining in the fuel tank 54 and outputs the detected fuel amount to the microcontroller 56. The fuel amount detection sensor 55 may be implemented by using a fuel gauge that is conventionally mounted on an automobile and is in use. The GPS receiver 57 receives the position data transmitted from the GPS satellites and outputs it to the microcontroller 56. The microcontroller 56 continuously determines whether the fuel amount has fallen below a certain criterion, and forms a data packet to be transmitted to the radio data exchange station (40 in FIG. 1) when the fuel amount has fallen below the predetermined criterion. The transmission data packet includes a unique number for the vehicle or device and GPS data indicating the current vehicle location. The modulator 58 modulates the transmission data packet and modulates it according to the signal format of the wireless data transmission system, and the transmitter 59 amplifies the modulated signal and outputs it through the antenna.

In one embodiment of the present invention, such transmission data packet formation and signal transmission may be performed immediately after the fuel amount drops below a certain criterion. However, in another embodiment of the present invention, the fuel quantity detection and determination is continuously made in consideration of the constantly changing position of the vehicle in operation, but the signal transmission is performed at the moment when the start of the vehicle is turned off or at a certain time such as in the evening This may be done at the time when the driver's activity generally ends. In addition, as described later, a signal may be transmitted when the driver presses a fueling application button of the input unit 64.

On the other hand, it is preferable that the vehicle to be refueled through the system of the present invention further includes a door open signal receiver 61 and a fuel filler door opening 62 so that even oil can be easily supplied to the vehicle. Do. The fuel filler door 63 is also provided with a barcode 64 on which information on the member ID is recorded. In addition, the input unit 65 may be additionally provided for the convenience of the vehicle driver.

The door open signal receiver 61 receives the door open signal from the outside and transmits the door open signal to the microcontroller 56. Here, the door open signal is generated even from the terminal possessed by the driver or the petrol station, and includes a password registered in advance for the vehicle by the member. The microcontroller 56 receives the door open signal and determines whether the password included in the door open signal is the same as that stored therein. If the password included in the door open signal is the same as that stored therein, the microcontroller 56 drives the fuel filler door opening 62 to open the fuel filler door 63. Accordingly, the fuel supply source can open the fuel filler cap and perform fueling. The fuel filler door opening 62 may be implemented using a solenoid.

The input unit 65 provides a fuel supply request button 65a used to artificially request fuel for the host and an emergency button 65b for making a request to the host in case of an accident, vehicle breakdown, or other disaster. Include. When the lubrication request button 65a is pressed, the microcontroller 56 forms a data packet to be transmitted to the radio data exchange station (40 in Fig. 1) and outputs it through the modulator 58 and the transmitter 59. When the rescue request button 65b is pressed, the microcontroller 56 forms a rescue request data packet. At this time, the rescue request data packet includes a specific data stream indicating the location information of the vehicle and the rescue request message. The rescue request data packet is also modulated by the modulator 58 and transmitted to the radio data exchange station 40, and the radio data exchange station 40 transmits the rescue request data packet back to the host 10.

Upon receipt of the rescue request data packet, the host 10 issues a rescue order to the jurisdiction 70, or even to the nearest location, or other service personnel. The rescue order includes vehicle number and position data of the vehicle. Accordingly, even the commanded driver or service agent moves to the vehicle location based on the vehicle number and the vehicle position data included in the rescue order, and rescues the vehicle driver who is in a rescue or repairs the vehicle.

FIG. 5 shows an example of equipment mounted on the oil tank 70 shown in FIG. 1. According to the embodiment shown in FIG. 5, the oil even 70 includes an oil tanker 120 for fueling a fuel tank, a PDA 140 for communicating with a host 10, and an oil operator or a gas source. A mobile phone 150 is provided which is used to talk to an operator or a customer.

The lubricator 120 is connected to the oil tank 122 through an oil tank 122, an oil supply hose, and an oil supply gun 124 for supplying fuel to a filler of a fuel tank to be refueled, and an oil supply gun 124. The flow meter 126 for measuring the flow rate of the oil supplied through the oil feeder, the oil feeder control unit 128 for controlling the operation of the lubricator 120 as a whole, and the flow rate data measured by the flow meter 126 through the oil feeder control unit 128. It includes a display 130 for receiving and converting the unit price and the amount per liter, and a communication interface 132 that enables communication with an external device such as a PDA 132.

The PDA 140 is connected to the host 30 through the wireless data exchange station 30 and the barcode reader 142 for reading the barcode 64 attached to the fuel filler door 63 of the vehicle near the member's fuel tank. A transmission / reception module 144 for carrying out data communication and transmitting a door open signal to the microcontroller 56 of the vehicle at the time of refueling is loaded. Meanwhile, as described above, the PDA 140 is preferably provided with a navigation system 146 so that the driver can easily grasp the location of the oil supply target, and the navigation system 146 is implemented in software.

Meanwhile, in FIG. 1, the fuel amount reading and signal transmission device 96 attached to the fuel tank of a building or a house may be configured similarly to the vehicle fuel amount reading and signal transmission device 96 shown in FIG. 4. However, in the case of a building or a house, since the position is fixed, in this case, the GPS receiver 57 becomes unnecessary. In addition, the input unit 65 may also be omitted in the building or house device. Furthermore, the fuel filler door opening mechanism, which is indicated by reference numerals 61 to 63 in FIG. 4, may also be selectively employed in the building or house apparatus.

The mobile fuel supply system of the present invention as described above operates as follows.

Figure 6 shows an embodiment of a mobile fuel supply method according to the present invention. The embodiment of FIG. 6 is suitable for refueling a vehicle. Referring to FIG. 6, first, the fuel amount reading and signal transmitting device 52 periodically reads the fuel remaining amount of the vehicle (operation 200). Then, the microcontroller 56 attached to the vehicle determines whether or not the amount of fuel is less than the first reference at every reading (operation 202). The first criterion is that the fuel tank is not emptied within a short time, but indicates a level at which fuel supply is required early, for example, about 1/4 of the fuel tank volume.

If it is determined in step 202 that the fuel amount is less than the first criterion, the fuel level reading and signal transmission device 52 transmits a fueling request packet of the first pattern to the host 10 (step 204). When the host 10 receives the refueling request packet, the host 10 stores information on the time and place where the driver desires to be refueled at the time of membership registration in the order DB.

On the other hand, the microcontroller 56 attached to the vehicle periodically determines whether the fuel amount is less than the second reference after the fuel amount is lower than the first reference (step 206). The second criterion is a level at which the fuel tank may be emptied within a short time, and may be, for example, the amount of fuel that a warning light enters the vehicle dashboard.

If the amount of fuel does not become less than the second standard before the time when the driver wants to be fixedly refueled at the time of membership registration (step 208), in principle, the fuel is supplied at a place previously set by the member in the desired time period (the Step 210). However, if the fuel amount becomes less than the second reference before the desired time period arrives, the fuel amount reading and signal transmitting device 52 periodically transmits a fueling request packet of the first pattern (step 212).

The host 10 checks whether the vehicle is in the location of the vehicle and whether the vehicle is in a stopped state based on the periodically received fuel request packet (step 214). If the vehicle is not in a stopped state and is on the move, and receives refueling from a nearby gas station, transmission of the refueling request packet is terminated (step 216). In this case, the host 10 deletes the order information about the vehicle from the order DB and ends the monitoring. However, if the vehicle is in a stationary state for a predetermined time in step 214, the host 10 writes the corresponding order information to the delivery DB and instructs to immediately refuel even for oil (step 218). Refueling is performed accordingly (step 220).

At the time of refueling, the refueling source operates the PDA 140 at refueling and inputs a predetermined password for the vehicle, thereby transmitting a door open signal to the microcontroller 56 of the vehicle. If the password is correct, the fuel filler door 63 is opened, and thus fueling is possible. When refueling is completed, the gas source reads the barcode attached to the fuel filler door 63 using the barcode reader 142, and the read vehicle owner or driver data is transmitted to the host 10 in real time along with the fuel flow information. . Meanwhile, in another embodiment of the present invention, vehicle owner or driver data and fuel flow information may be uploaded to the host 10 by a batch operation at a predetermined time or aperiodically.

On the other hand, when the fuel amount is less than the second reference in step 206 of FIG. 6, the driver may request to refuel immediately by pressing the oil filling request button 65a attached to the vehicle. 7 shows the refueling procedure in this case. First, when the driver presses the oil filling request button 65a, the fuel level metering and signal transmitting device 52 transmits the oil filling request packet of the second pattern to the host 10 (operation 230). The oiling request packet of the second pattern includes a unique vehicle identification number (ID) and vehicle position data similarly to the oiling request packet of the first pattern, but a field indicating a priority is configured differently from the packet of the first pattern. do. Receiving the oil request packet of the second pattern, the host 10 records the order information in the order DB and the delivery DB, and instructs to immediately refuel even for oil (step 232). (Step 234).

8 shows another embodiment of a mobile fuel supply method according to the present invention. 8 is suitable for refueling a fuel tank of a building or a house. Referring to FIG. 8, first, the fuel amount reading and signal transmission device 96 attached to a fuel tank of a building or a house periodically reads the remaining fuel amount, and determines whether the fuel amount is less than the third standard at every reading (first step). Step 240, step 242). The third criterion is a level at which the fuel tank is likely to be empty within a short time, and specific values may be set differently according to the volume of the tank and the fuel use.

If it is determined in step 242 that the fuel amount is less than the third criterion, the fuel amount reading and signal transmission device 96 transmits a fueling request packet to the host 10 (step 244). At this time, the fueling request packet transmitted from the device 96 does not include the position data of the fuel tank. When receiving the fuel request packet, the host operator may check whether to refuel to the manager or the owner of the building (step 246). If the building manager or house owner disagrees (step 248), the refueling process ends. However, if the building manager or house owner agrees to refueling in step 248, the host operator stores the order information in the order DB and the delivery DB. Accordingly, the host 10 instructs to refuel even oil (step 250), and thus oil supply is performed (step 252).

The above description illustrates a preferred embodiment of the present invention, and the present invention is not limited thereto and may be variously modified. For example, in the embodiment of FIG. 1, the RF data 40 directly receives the RF signals transmitted from the vehicle or the building fuel tank, but in another embodiment of the present invention, separate base stations receive the RF signals after receiving the RF signals. The received signals may be transmitted to the radio data switching center 40.

Meanwhile, in the above description, the fuel supply system of the present invention is mainly focused on the fuel supply system. In the mobile fuel supply system of the present invention, the microcontroller 56 of FIG. After installing sensors and transducers in place, these transducers can be interfaced to the microcontroller 56. An example of where transducers are installed may be a odometer. In this case, the host 10 may recommend a time of exchanging consumables such as engine oil to the corresponding member based on the mileage data of each member vehicle.

In addition, in the above description, communication between the fuel amount reading and signal transmission device 52 mounted on the vehicle and the host 10 is one-way, but in another embodiment, the vehicle device and the host 10 may perform bidirectional communication. have. In such an embodiment, the host 10 may provide additional services for traffic information, living information, or the like, or provide music data to the vehicle driver.

On the other hand, while in the preferred embodiment, the refueling vehicle 50 or even oil 70 uses a wireless data network for transmitting and receiving data with the host 10, in another embodiment of the present invention, other wireless communication networks such as bidirectional. A wireless call network or the like may be used. In addition, by designing a terminal that can implement only the data transmission function of the cellular phone and mounted in the vehicle, it is also possible to transmit and receive data through the cellular communication network. Since such modified embodiment can be easily implemented by those skilled in the art or wireless communication field, the detailed description thereof will be omitted.

In another variant of the system for refueling fuel tanks in homes or buildings, the fuel supply request signal is transmitted through the Internet, which is expected to be fully supplied to each home and the like in connection with a home networking system or a home automation system that will be common in the future. It can also be sent. In this case, by connecting the fuel level sensor of the fuel tank to a network adapter for internet connection, a signal indicating a fuel shortage or fuel supply request may be transmitted to the host 10 by the TCP / IP protocol.
