Then, the center instructs the parts subcontractor at what time to deliver a certain part to the loading station of the vehicle assembly line.The subcontractor then loads the instructed parts onto the vehicle. At a predetermined time, the part enters the factory, passes through a gate, and delivers the part to a predetermined parts delivery station.Then, at this delivery station, that is, the parts receiving station, the contents of the cargo are compared with the shipping slip, and the receipt is confirmed. It is done.

Thereafter, the receiving status of parts is input to the center from a terminal installed at this receiving station.

[Problem that the invention seeks to solve]

In such a system, it is necessary for the center to quickly and accurately grasp the flow of parts, production status, etc. throughout the factory in order to operate the manufacturing and assembly lines smoothly.

However, with the above conventional method, it is not possible to know when the vehicle from the outsourcing company arrives at the factory, and even if the cargo is received at the receiving station, this information is not input from the terminal at the receiving station. However, the center cannot confirm acceptance. Furthermore, in the conventional method, the contents of the cargo are manually checked at the receiving station, and the contents are inputted from a terminal, but errors in the confirmation or input operations on the terminal may occur.

In this way, with the conventional method, it is difficult for the center to accurately and quickly grasp the flow of parts throughout the factory, and there is a problem in that it is not possible to operate production lines such as 9 assembly lines smoothly. Ta.

This invention was made in view of the above points, and it is possible to use an IC card to accurately and quickly grasp the flow of objects in various systems such as a production management system, thereby facilitating smooth operation of the system. I that can be operated to
The purpose is to obtain a C card control system.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Here, a case where the IC card control system of the present invention is applied to a vehicle entrance/exit and cargo acceptance management system will be described. FIG. 1 shows an example of the configuration of this vehicle entry/exit and cargo acceptance management system. In the figure, 20 is a gate station that manages vehicle entry/exit, and 30 is a reception station that manages the acceptance of vehicle cargo. A station 40 is a processing device that processes each device at each of these stations, and is provided at the center.

At the gate station 20, 1 is a truck loaded with cargo 2, and 4 is an IC card owned by the driver of this trunk 1. As shown in FIG. It incorporates a one-chip microcomputer 41 having a storage memory 41b and a RAM 42 as a data memory. In this data memory 42, the vehicle number of the truck 1 is stored in a memory area 42a, and data regarding cargo is stored in an area 42b. Further, 51 is a card terminal for reading data from and writing data from the IC card 4;
8 is a sensor for detecting the arrival of truck 1; 10 is an illuminator for illuminating the license plate 3 of truck 1; 6
is a TV camera to read the number of track 1, 7
is a gate, and 9 is a destination indicator for displaying the destination for the trunk 1.

Further, at the receiving station 30, 52 is a card terminal similar to the terminal 51 at the gate station 20, 11 is a barcode reader that reads the barcode on the label 2a affixed to the cargo 2, and 12 is a display terminal.

Next, the operation will be explained.

FIG. 3 is a diagram for explaining the operation of the system of this embodiment, in which reference numeral 13 indicates entry management at the gate station 20, reference numeral 14 indicates cargo acceptance management at the receiving station 30, and reference numeral 15 indicates the flow of exit management at the gate station 20. It shows. The operation at each station will be explained below with reference to FIG.

First, entry management at the gate station 20 will be described. When the trunk 1 arrives at the factory entrance gate, the sensor 8 detects this arrival, and the detection signal is input to the processing device 40. As a result, the processing device 40
A drive signal is output to each device. That is, first, the illuminator 10 is driven as necessary to illuminate the license plate 3 of the trunk 1, and the TV camera 6 reads the vehicle license plate number. This data is sent to a processing device 40, which outputs the data to a card terminal 51. When the driver inserts the IC card 4 in hand into the card terminal v&51, the vehicle number data sent from the processing device 40 is temporarily stored at memory address A of the temporary storage memory 41b of the IC card 4. is memorized.

Then, this stored content is compared and verified within the card 4 with the content previously stored at the memory address 42a of the data memory 42 of the card, and if the verification results in a match, a match output is output to the processing device 40. The processing device 40 that receives this coincidence output outputs a drive signal to the gate 7, thereby opening the gate 7. At this time, the processing device 40
A time signal is output to the card terminal 51, and this signal, that is, a signal indicating the entry time of the truck 1, is written into the data memory 42 of the IC card 4.

Further, the data regarding the cargo written in the memory area 42b of the IC card 4 is transferred to the processing device 4 via the terminal 51.
Based on this, a predetermined arithmetic process is performed in the processing device 40, and a signal indicating the destination of the truck 1, which is the result of the arithmetic operation, is output to the destination display 9. As a result, the receiving station to which the truck 1 should go is displayed on the destination display 'a9. Seeing this, the driver of the trunk 1 removes the IC card 4 from the card terminal 51 and proceeds to the predetermined receiving station. The gate will be closed after passing through.

Next, at the receiving station 30, the barcode of the cargo 2 unloaded from the truck 1 is read by the barcode reader 11 and sent to the display terminal 12. On the other hand, as mentioned above, the data regarding the cargo 2 in the trunk 1 is written in advance in the data memory 42 of the IC card 4, and this
By inserting the C card 4 into the card terminal 52, the display terminal 12 reads data regarding the cargo.

Each of these data is compared and verified in the processing device 40, and if the verification matches after confirming receipt of the consignment, the processing device 40 outputs the confirmed data, and the data is displayed on the display terminal 12 and the card terminal 52. The data is written to the data memory 42 of the IC card 4 via the IC card 4, and the acceptance work is completed.

Furthermore, exit management at the gate station 20 is similar to the operation at the time of entry, and the exit time is written on the IC card 4.

Here, when writing or reading data to or from the IC card 4, the memory area 4 of the data memory 42 is
The type of data written to the card 2b corresponds to the program content of the program recording memory 41a, so by appropriately selecting the program content on the processing device 40 side, a predetermined type of data is written in the card 4 or Arithmetic processing is performed within the processing device 40, and the arithmetic results are written into and read out from the card 4.

In this embodiment, IC cards are used to manage the entrance and exit of vehicles and the acceptance of cargo, so that the vehicle, that is, the necessary parts, etc., can be monitored from the moment they enter the factory premises. Movement can be managed at the center, and since it is done with almost no human intervention, it can be managed accurately and quickly. In particular, at the gate station 20, intrusion of vehicles other than contracted vehicles can be prevented, and moreover, the working status of the vehicle can be confirmed based on the entry/exit time data written on the IC card 4. Furthermore, since the destination of the vehicle is automatically displayed according to the contents of the cargo, even if the driver of the vehicle does not know the inside of the factory, he or she can easily reach a predetermined receiving station.

In addition, at the receiving station 30, it is possible to confirm the acceptance of cargo without handling any slips, that is, in a paperless manner.Furthermore, since there is no human intervention unlike in the past, mistakes in cargo confirmation, terminal input errors, etc. is gone,
Accurate and prompt acceptance management can be performed. Incidentally, if a slip is required, it is also possible to easily issue a slip by providing a printer in the display terminal.

Furthermore, in the above embodiment, data is recorded on an IC card, so compared to conventional magnetic cards, a large amount of data can be handled, and moreover, the data can be lost.

There are no changes and there are no problems with reliability.

In addition, in the conventional system that handles slips, there is a possibility that the contents can be read by a third party, but as in this embodiment,
By adopting the C card, it is possible to prevent information from leaking to a third party.

In the above embodiment, the present invention is applied to a management system for vehicle entrance/exit and cargo acceptance, but it goes without saying that the present invention can also be applied to a system that manages either one of them. The present invention can also be similarly applied to shipment of cargo, that is, to a shipping system.

In particular, the vehicle entry/exit management system can also be applied to entry/exit management of parking lots and the like. That is, in conventional parking lot management, the contracted vehicle number is registered in a processing device in the management room, and the number of the entering vehicle and its registered number are compared and verified by the processing device, but the present invention In the accepted system, the registration number is recorded on the IC card, and
Comparison and verification is performed within the card, so the processing device in the control room simply reads the number of the entering vehicle, sends it to the card terminal, receives the verification result from the card, and sends out a gate control signal. That's fine.
