Description

Refueling management device and method of self-lubricator {omitted}

The present invention relates to a refueling management device and method for a self-lubricating machine for recognizing an RF card possessed by a gasoline when refueling using a gasoline installed in a self-fueling station so that only the oil that can be handled by the gasoline can be supplied. .

In general, large factories, bus transportation companies, freight companies, car shipping sites, military units, etc. have their own gas stations, and a separate gasoline is assigned to refuel the vehicle.

However, such a conventional self-filled gas station has a high labor cost because it has to arrange a gasoline crew even if no gas is generated, and the burden on the double work is accompanied because it requires manual finishing of the filling data and the finishing data on the fueling vehicle. In addition, random data operations have led to unreliable data management.

At the time when oil management is important due to high oil prices, the company is always exposed to risks such as oil loss and theft, which are company assets.In addition, accurate shipping data are not provided even in the oil tank, ie inventory management. We have used a very primitive method of checking the amount of oil by inserting.

This primitive method of flow management raises the risk of fire and environmental problems due to the frequent opening and closing of manholes in oil tanks, and also involves unnecessary manpower consumption.

In addition, when a fuel tanker incorrectly classifies oil types (for example, when gasoline is supplied to a diesel vehicle), a serious problem may occur that causes damage to the vehicle.

The present invention is to solve such a conventional problem, the oil is authorized to have an own RF card, the oil permits and the type of oil to be handled is input to the RF card, it is recognized by the RF reader installed in the gas tank approved In addition, the lubricator operates only to those who are approved for lubrication, thereby providing a lubrication management device and method for self-lubricator to prevent unnecessary oil loss and theft.

In addition, the information on the tanker and the fueling is made into a database to automate the inventory management of the oil tank.

Oiling management device of the present invention self-lubricator for achieving this problem,

Lubricator for oiling,

An RF card reader installed in the lubricator,

RF card which is carried by the gasoline and records the information on the oil certification and the type of oil handled;

Enables fueling by lubricating the corresponding oiler according to the RF card information read by the RF card reader, and transfers the oiling information and flow level information read from the oil tank level gauge to the computer, and approval of the oiling machine transmitted from the computer. A controller for controlling the lubricator according to the flow rate information,

It consists of a computer to database the information sent from the controller.

The fuel management device of the self-lubricator according to the present invention having such a structure leads the oiler's authentication information from the RF card so that the oil and the flow rate can be accurately fed, thereby not only theft and waste of unnecessary oil, but also the damage of the vehicle due to incorrect fueling. It is effective to prevent.

In addition, there is no need to manage fueling, oiling information, etc. as a separate gas station resides to prevent unnecessary manpower consumption. Automated inventory management can be achieved by automatically identifying the information of oil supply and inventory of oil tanks and making them into a database.

As a result, it is possible to fully automate the entire filling operation at the self-service station.

Hereinafter will be described with reference to the accompanying drawings, the integrated control device of the fueling equipment according to the present invention.

1 is a view showing the entire system of the present invention, the RF card 600 is carried by a person authorized to refuel (for example, a vehicle driver), the chip inside the personal information (for example code number) ) And oil types (petrol or diesel) are stored.

The RF card 600 may use RF_TEG.

The lubricator 500 is equipped with an RF reader 510 for reading information stored in the RF card 600. When a person holding the RF card 600 approaches, the information is read from the controller 100 to the controller 100. Will be sent.

Then, the controller 100 confirms whether the member can be refueled from the read information, and also checks the handled oil to enable the corresponding fuel tanker.

That is, if the fuel permitting driver is a diesel vehicle driver, only the diesel fueling machine is enabled among several gasoline tankers to prevent erroneous fueling in advance.

When the lubrication permitter grabs the handle of the lubricator and grabs the handle, the controller 100 starts the lubrication by driving the motor inside the lubricator 500, but if the lubrication is not performed for a predetermined time (for example, about 30 seconds), the controller 100 disables the lubricator 500 to prevent oil from being made.

This is to prevent other people from refueling if the licensor leaves the lubricator for many reasons.

During refueling, the controller 100 confirms the approved refueling amount of the corresponding permit holder through communication with the computer 300 through the communication line 400, and then disables the refueler 500 when the cumulative refueling amount is exceeded, forcibly terminating the refueling. Let's do it.

This is to prevent unnecessary waste of oil by permitting only a certain amount of oil for a given period of time, and the fuel information of the gasoline permitter is stored in the database of the computer 300. Therefore, the controller 100 has the accumulated fuel flow information for a predetermined period, so that the controller 100 controls the oil pump 500 with this information.

When the fueling is forcibly terminated or normally terminated, the controller 100 transmits the fueling information to the computer 300 through the communication line 400 so that the computer 300 updates the database.

At the same time, the controller 100 reads the information on the flow level from the level gauge of the oil tank 700 and transmits the information to the computer 300 to update with the oiling information so that inventory management is integrated.

FIG. 2 is an internal circuit block diagram of the controller 100 of FIG. 1, in which a button unit 110 for setting the controller 100 and a display unit 120 for visually expressing an operation state are provided.

In addition, a port unit 130 including a plurality of serial ports and a LAN port 140 for communicating with a remote computer 300 through TCP / IP is provided.

Port 130 is composed of a serial port, such as RS485 or RS422 in order to connect with the level of the circuit and the oil tank 700 built in the oil tanker.

At this time, any one port of the port unit 130 is connected to the level gauge is set as a port for supplying power of 24-28V which is the operating power of the level gauge.

A communication line, that is, a LAN cable 400 is connected to the LAN port 140 and communicates with the remote computer 300 through the TCP / IP protocol to communicate data.

The communication unit 150 operates in accordance with the TCP / IP protocol and is responsible for converting data transmitted and received.

The program storage unit 180 stores an operation program for transmitting to each lubricator and setting it on its own, and a program for operating a level gauge. Such an operation program is performed to perform an operation according to the manufacturer, the lubricator model, etc. of the lubricator. The operating program stored therein can be updated by being received from the computer 300.

In other words, even if the lubricator or level gauge is replaced, by only updating the operation program accordingly, integrated control is possible without having a separate controller.

The coupler 170 performs physical and electrical interfacing between the port 130 and the CPU 160.

The power supply unit 210 converts and supplies external commercial power into a form of power for the controller 100 to operate, and at this time, a power of 24-28V supplied from the power supply unit 210 is applied to any of the port units 130. It is connected to one port 'D' port to apply the operating power when the level gauge of the oil tank 700 is connected thereto.

Since the level gauge of the oil tank 700 is not supplied with a separate power, the data sensed therefrom is input while supplying power using the port.

The backup battery 190 is used to maintain the data stored in the memory 200 transmitted from the lubricator and the backup battery during power failure so as not to be lost.

The CPU 160 collectively controls the operation of the present invention, and the operation relationship will be described based on this.

It is assumed that the lubricator 500 is connected to the 'A', 'B', and 'C' ports of the port unit 130, and the level gauge of the oil tank 700 is connected to the 'D' port.

When the administrator applies a command for setting the operation program of each lubricator 500 through the button unit 110, the CPU 160 receives the command and displays a list of the operation programs stored in the program storage unit 180. It is displayed through the unit 120.

Since the manager already knows the manufacturer and model name of the lubricator, when selecting the operation program corresponding to the lubricator 500 connected to each port of the port unit 130 while looking at the displayed list, the CPU 160 is a program storage unit The operation program of each lubricator 500 stored at 180 is supplied to each port 130 through the coupler 170.

Therefore, the selected operation program is transmitted to each lubricator connected to the port unit 130 and is set from the internal circuit so that the lubricator 500 operates according to the operation program, and the data from the lubricator 500 generated during operation is It is provided to the CPU 160 through the port 130 again.

The data transmitted from the lubricator 500 may be a variety of information such as information of the lubrication permitter read from the lubricator RF card 600, the lubricator unique ID, nozzle on / off, lubrication amount, lubrication time.

The CPU 160 updates the database by transmitting it to the computer 300 through the communication unit 150 accordingly. Also, when the operation program is received from the computer 300 through the communication unit 150, the program storage unit 180 is updated. Updates are made by storing them in.

The case of controlling the level gauge installed in the oil tank 700 is different from this, but since the level gauge does not have a function of storing and setting its own operation program, it must be controlled by operating it directly in the integrated control apparatus 100 of the present invention.

To this end, after the operating power is supplied from the power supply unit 210 through the 'D' port, the data sensed through the 'D' port is received by the CPU 160 and then the program is stored in the program storage unit 180. The data is analyzed and the analyzed data is transmitted to the computer 300 through the communication unit 150.

At this time, the CPU 160 becomes data such as a unique ID transmitted from the level gauge and the height of the oil level. Computer 300 is to use the database to manage the transmitted data.

On the other hand, when the computer 300 is powered off due to a power failure, the CPU 160 detects this through the communication unit 150 and then accumulates and stores the data transmitted from the lubricator and the level gauge in the memory 200. When the power failure is restored, the CPU 160 reads data stored in the memory 200 and transmits the data to the computer 300 through the communication unit 150.

In addition, when the power supply plug is unplugged or the power supply is not supplied to the controller 100 due to other reasons, the data input from the lubricator and the level gauge does not reach the computer 300 and all of them are lost.

This loss of data is a major obstacle to reliable business management.

In order to prevent this, a backup battery 200 is provided. In the event of power failure, the data transmitted from the lubricator and the level gauge are accumulated in the memory 200 by the CPU 160 by operating the present invention by the backup battery 200. When the power failure is restored, the CPU 160 reads the data stored in the memory 200 and transmits the data to the computer 300 through the communication unit 150.
