Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is provided with a plurality of lorry spots, such as a shipping base and a receiving base that are configured to load and discharge a liquid cargo such as LNG and LPG with respect to a lorry tank that enters each lorry spot. The present invention relates to a method and an apparatus for identifying a lorry tank for identifying which lorry tank is located in which lorry spot in a facility.
[0002]
[Prior art]
In general, trailer-type lorry vehicles are widely used as means for transporting a liquid cargo such as LNG and LPG.
[0003]
When such a trailer-type lorry vehicle is operated and, for example, LNG is shipped as a cargo, at the shipping base, there is a need to manage the shipping loading amount, so that there are a plurality of lorry vehicles at the shipping base. Of the provided lorry spots, it is necessary to know exactly how much LNG has been loaded and how much LNG has been loaded. In addition, the receiving base manages the amount of lorry vehicles to be paid out. From the necessity, it is necessary to know exactly which lorry vehicle is located in the lorry spot that is installed in the receiving base and how much LNG is paid out. Therefore, it is important to identify the lorry vehicle that is the target of the loading operation and the payout operation and the lorry spot where the lorry vehicle is installed.
[0004]
For this reason, conventionally, each lorry vehicle driver possesses an ID card, and the card reader provided for each lorry spot at the shipping base or receiving base reads the ID card. Each lorry car is identified by reading the license plate of the lorry car that has been installed, using a method that enables identification of the lorry car that has been installed in the vehicle, and an imaging device provided for each lorry spot at each shipping base and receiving base. I was trying to let them.
[0005]
By the way, in the conventional trailer type lorry vehicle, the lorry tank is integrated with the trailer, but in recent trailer type lorry vehicles, the lorry tank is separated from the trailer, and the lorry tank is attached to and detached from the trailer. In this type of trailer type lorry vehicle, for example, a lorry tank transported by a lorry vehicle is transferred to a certain point on a railroad by transferring the loaded cargo to a freight car and then transported to a certain point. There are cases in which the trailer and the lorry tank are separated from each other, for example, the tank is transferred from a freight car to another lorry and further transported.
[0006]
[Problems to be solved by the invention]
However, when the trailer and the lorry tank are separated and operated, the lorry tank mounted on one trailer is changed. Therefore, in the conventional method of reading the ID card or license plate, it is not possible to identify the trailer. Even if it is possible, there is a problem that the lorry tank cannot be identified, and if a tank identification defect occurs, there is a problem that it leads to a defect in the management and automation of the shipping load amount and the payout amount.
[0007]
In order to cope with this, a method of attaching a plate with an ID number to each lorry tank and identifying the plate by reading the ID number of the plate with an imaging device is conceivable. There is a problem that misidentification may occur due to a shift in the stop position, the weather, particularly the influence of snow in a cold region, and the like.
[0008]
Incidentally, if an ID number is assigned to each lorry tank and this is input by a human key operation, the possibility of erroneous identification as described above is reduced, but in this case, the possibility of human error cannot be excluded. There is a problem.
[0009]
Therefore, the present invention is intended to provide a lorry tank identification method and apparatus capable of reliably identifying a lorry tank that is a target of loading work and payout work by eliminating erroneous identification and human error. .
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention allows a lorry tank, which is detachably mounted on a trailer type lorry vehicle, to be inserted into a plurality of lorry spots by a trailer type lorry vehicle , and the liquid in the lorry tank is removed . the communication interface unit is installed in each of the one Raleigh spot in facilities you have to carry out the loading and / or payout of cargo, originating which had been equipped Raleigh tank of the trailer type lorry that entry permit to enter the b over Lee spots connect the instrument to communicate with the originating instrument and the communication interface unit with feeding to the calling instrument, based on the ID signal transmitted in the transmitting instrument at the communication interface unit, the originating instrument By identifying the low to which the transmitter is attached Identifies Tanku, and to the originating meter based on the communication interface unit in communication with the identified Raleigh tank entry permit to enter to have Raleigh tank identification method and apparatus to perform the identification of the lorries spots.
[0011]
After the lorry tank is installed in the lorry spot, when the transmitter instrument installed in the lorry tank and the communication interface unit installed in the lorry spot are communicably connected, the ID signal transmitted by the transmitter instrument is sent to the communication interface unit. In response, the communication interface unit identifies the transmitting instrument based on the ID signal, and identifies the lorry tank to which the transmitting instrument is attached. At this time, since the communication interface unit has a one-to-one correspondence with the lorry spot, the identified lorry tank is installed by specifying the communication interface unit communicating with the transmitter. A lorry spot is identified.
[0012]
In addition, the liquid level of the cargo stored in a lorry tank equipped with a transmitter that is configured to communicate with the communication interface unit by connecting to the communication interface unit provided for each lorry spot. the level of data, by transmitting along with the ID signal by the originating meter, at the communication interface unit performs identification of Raleigh tank, based on the shape data and the level data of the identified Raleigh tank, the identified Raleigh With the method and apparatus for calculating the amount of load in the tank, the amount of load stored in the lorry tank can be easily grasped simultaneously with the identification of the lorry tank.
