BACKGROUND OF THE INVENTION
The present invention relates to an oil supply management system for an oil station when oil is supplied from a tank truck to an oil storage tank of the gas station.
[0002]
[Prior art]
Conventionally, when unloading to an underground storage tank of a gas station using a tank truck, a so-called witnessed unloading is performed, in which an administrator of the gas station witnesses and checks the unloading quantity and oil type on the spot after unloading. It was. On the other hand, from the viewpoint of improving transportation efficiency, so-called single unloading is also performed, in which unloading is performed at a time when the traffic volume is relatively low, such as early morning, late at night, or a holiday. A gas station that performs such unloading is equipped with a monitoring and control device to prevent over-injection in conjunction with the oil level gauge of the oil storage tank, and the tank truck manages the oil in each hatch. If the vehicle-mounted control device and the monitoring control device at the gas station are connected and communication is not normally performed, unloading cannot be performed.
[0003]
[Problems to be solved by the invention]
However, the gas stations that are equipped with monitoring and control devices and can be unloaded alone are part of the whole, and in gas stations with witnessed unloading, this type of on-board control device is connected to the monitoring and control device of the gas station. In some tank trucks that must communicate with each other, unloading may not be possible.
[0004]
The present invention has been made in view of the above circumstances, and an object thereof is to provide an oil supply management system for a gas station that enables unloading regardless of the presence or absence of a monitoring control device at the gas station.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the loading data storage means for storing the unloading destination data including the hatchery-controlled gas station code, the card reader, and whether or not unloading is possible are determined. An unloading determination unit and a valve opening / closing control unit that controls opening / closing of the unloading valve of each hatch by the unloading determination unit are provided in the oil storage tank of the oil filling station by a tank lorry. In an oil supply management system for a gas station that unloads with a connected oil supply pipe, an oil type key is provided in the vicinity of the oil supply port on the ground of the oil supply pipe, and the tank lorry has a valve opening / closing control unit for each hatch. A manual bottom valve having a lock means to be controlled is provided, and the discharge controlled by the valve opening / closing control unit between the connection port connected to one of the oiling hoses and the manual bottom valve. A valve is provided, and the other connection port of the oil supply hose has a connection part connected to the ground oil supply port of the oil supply pipe and an oil type sensor connected to the oil type key to detect the oil type. Provided with a monitoring control device that is connected so that a detection signal of the oil type sensor is transmitted to the unloading availability determination means of the in-vehicle control device and outputs a valve closing signal when the upper limit amount of the oil storage tank is exceeded. In the gas station, the monitoring control device and the in-vehicle control device are connected by a signal line to control the unloading. In the gas station not equipped with the monitoring control device, the unloading destination information including the gas station code is stored. The stored gas station card is read by the card reader, and unloading is controlled by determining the coincidence with the gas station code recorded in the loading data storage means. Unloading is possible regardless of the presence or absence of a monitoring control device at the gas station. Applicable to tank truck with manual bottom valve.

Next, when there is no gas station card 40, it is a gas station that can be unloaded with the monitoring control device 21, and the in-vehicle control device 37 of the tank truck 31 and the monitoring control device 21 are connected by a signal line 45 ( ST8) When the connection is correctly made (ST9), the supervisory control device 21 is enabled (ST10).
[0015]
Next, when the filling station card 40 is read and an unloading permission is output (ST4), or when the monitoring control device 21 becomes operable (ST10), one end of the oiling hose 36 is connected to the tank lorry 37. The oil type signal detected by the oil type sensor 35b is input in a state where the other connection part 35a and the oil type sensor 35b are connected to the predetermined oil supply port 13 and the oil type key 14 (ST5). The hatch number is input from the keyboard 38 (ST6). Next, when the oil type and the gas station code detected by the oil type sensor 14 coincide with the gas station code and the oil type stored in the cargo data storage unit 41 in advance (ST7), An open signal is output to the valve opening / closing control unit 44 (ST11), so that unloading is possible. The valve opening / closing control unit 44 that has received the valve opening signal opens the air-type bottom valve 33 corresponding to a predetermined hatch No, and starts to lubricate the oil storage tank 11. On the other hand, in the oil supply tank control device 16, the scanning means 17 scans the oil level gauge 15 (a, b, c) and stores it in the liquid amount storage means 18, and the comparison means 20 stores the liquid stored in the liquid amount storage means 18. The amount is compared with the upper limit amount stored in the upper limit amount storage means 19 in advance. When the monitoring control device 21 receives a signal exceeding the upper limit value from the comparison means 20 (ST21), the valve closing signal output means 22 outputs a valve closing signal to the in-vehicle control device 37 (ST22). Upon receiving this valve closing signal, the in-vehicle control device 37 outputs the valve closing signal to the valve opening / closing control unit 44 by the unloading availability determination means 44 and closes the pneumatic bottom valve 33, thereby preventing the loading oil type from flowing out. The
