Abstract

PURPOSE:To increase the speed of measure per truck scale so as to improve the measure capacity by removably fitting an ID card to a car body of a truck, and disposing an antenna and a controller in a position of a truck scale site where communication is possible, thereby performing unmanned giving and receiving of information. CONSTITUTION:An ID card 5 where information is written by a computer 12 of an office is fitted to a designated spot of a truck, the truck starts for A measure place. When the truck is put on truck scales 31, 32, truck management information is read from micro waves generated from antennas 61, 62, and the complete vehicle dead weight is written in the ID card through controllers 71, 72 to be printed by printers 81, 82 and be sent to a computer 11. Subsequently, when the truck is loaded with cargo in a cargo handling place, and the truck is again put on the track scales, the loading weight is written to be printed and stored in the computer 11, and the loadage is calculated from a difference between the loading weight and the vehicle dead weight.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management system for grasping an accurate amount of cargo unloaded from a bulky ship.

[0002]

2. Description of the Related Art The amount of ore received by a bulk carrier is finally checked by trucks (usually by accumulating the load of dump trucks, and the amount of valuable metals in ores is sampled for each truck). The weight of the truck is measured in the loaded state and the weight of the empty truck is subtracted from the content of the analytical sample and the amount of the received sample.

By the way, the above-mentioned ore is normally received by a plurality of trucks, and empty truck weight measurement, loading, loading weight measurement and unloading are repeated. However, the truck scale 1 is used to record and calculate the weighing result. At least one person was required.

Recently, in order to reduce errors in calculation and recording and speed up acceptance management, a small computer is connected to the truck scale, and a unique number (abbreviated as car number) is assigned to each truck each time it is weighed. Although it is only necessary to input, one truck scale requires two weighings in order to obtain the loading capacity at one time, which was a bottleneck in the receiving work.

The above problem can be solved by adding a truck scale and connecting it to a computer, but the number of scales is increased due to the input of the vehicle number.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a system that eliminates the number of personnel to be placed on a truck scale and is capable of unmanned and speedy receipt management.

[0007]

To achieve the above object, the system of the present invention comprises a plurality of track scales,
An antenna unit and controller of a remote ID system arranged at each track scale site, a computer for processing information from each controller and the track scale, and connected to the computer for inputting and recording identification information in each ID card The computer is equipped with a remote ID system and the ID card is attached to the bodies of a plurality of trucks and is capable of reading and writing information by the antenna unit.

[0008]

The system of the present invention owes much to the remote ID system. This remote ID system is a mobile body identification system that uses microwaves, and it uses radio wave communication between a controller, an antenna unit, and an ID card so that data on an ID card at a remote position can be read and written. The communication is possible if the distance between the antenna and the ID card is within several meters.

In the present invention, the ID card is removably attached to the body of the truck, while the antenna and the controller are arranged in a communicable position on the truck scale site.
We made it possible to send and receive information unattended.

FIG. 1 is a diagram showing an embodiment of the system of the present invention. It is composed of an A weighing station system, a B weighing station system and an office system, and a BASIC language parallel computer is installed in a computer 11 installed in the A weighing station. Converters 41 and 42 for converting the weight signals of the track scales 31 and 32 into electric signals via a progressive programmable logic controller (hereinafter abbreviated as high-performance PLC) 21, and an antenna unit for reading and writing information in the ID card 5. 6
Controllers 71 and 72 for controlling 1 and 62, and printers 81 and 82 for printing these information are connected, and
It is also connected to the PLC 22 of the weighing station, the computer 12 of the office, and the auxiliary storage device 91 so as to collect all the information. PLC22 has a track scale 33
Controller 73 of the antenna unit 63 that reads and writes the information of the weight signal converter 43 and the ID card 5
And a printer 83 are connected to the computer 12
Antenna unit 64 for writing identification information to D card 5
A controller 74 for controlling the printer, a printer 84, and an auxiliary storage device 92 are connected.

On the day of unloading work, truck management information such as a car number and a cargo handling location is input from the terminal of the computer 12 in the office according to the work allocation to the trucks that can be operated on that day, and the ID card is input through the controller 74 and the antenna 64. The information is written in 5, and printed by the printer 84, and at the same time, the same information is sent to and stored in the computer 11 at the weighing station A. When the ID card 5 is attached to a predetermined location of the truck and facing the A weighing station, and the truck is placed on any of the truck scales 31 or 32, the truck management information is read by the microwaves emitted from the antenna 61 or 62. If the cargo handling location corresponding to the vehicle number is correct, the empty vehicle weight is written in the ID card 5 via the controller 71 or 72, printed by the printer 81 or 82, and also sent to the computer 11.

Next, when the truck is loaded with cargo at the loading area and placed on any of the truck scales again, the loaded weight is written in the same procedure as described above, printed by the printer and stored in the computer 11, and the empty vehicle weight is recorded. The loaded luggage amount is calculated from the difference between It is sufficient that the truck lowers the load to a predetermined storage place and repeats the operation from weighing of the empty vehicle again, and during this period, the weight measurement proceeds completely unattended. The driver just puts the truck on the scale and does not have to do anything outside.

FIG. 1 is representatively shown at the B weighing station to show that a plurality of weighing stations can be used. When weighing is performed at a distant place, PLCs may be placed and connected to the computer 11.

The computer 12 at the office is used to check the received amount.
Can be performed in real time and can be printed by the printer 84. If a display panel is provided at each truck scale site, the destination of the truck can be used as the truck management information, and the work can be continued without any trouble even if the driver changes during the loading and unloading.

If the load is powdery or lumpy, it is transferred from the ship to a hopper by a belt conveyor or the like, and a predetermined amount is cut out from this hopper and loaded on a truck. It can be used to detect scale anomalies.

In addition, the data of the ID system abnormality is PLC.
If it does not come in for a certain period of time, an alarm can be issued and it can be detected early.

[0017]

According to the present invention, the weighing per truck scale is speeded up, and the weighing capacity is greatly increased together with the addition of the truck scale.
It was possible to raise 00T / hour to 800T / hour.
