JP 2002-278773 A

  FIG. 10 is a configuration block diagram showing an example of such a conventional position information collection system. In FIG. 10, 1 is a database in which location information is stored, 2 is a data processing device having wireless communication means, 3 is a relay device that relays wireless communication, 4 is a control device that controls a specific device, and 5 is an operator. is there.

  The database 1 is connected to the data processing device 2, and the data processing device 2 is connected to the relay device 3 through a wireless communication path. The relay device 3 is connected to the control device 4 through a wireless communication path. Further, the worker 5 can access the database 1 from a terminal device (not shown).

  Specifically, the control device 4 is installed in a belt conveyor of a factory production line, a pipeline in a plant, a railroad crossing or a station, etc., and acquires data of various sensors and measuring instruments, measuring instruments and other It has functions such as device control and wired and wireless network interfaces.

  For example, assuming that the control device 4 is installed on a belt conveyor of a factory production line and obtains data of a sensor for identifying a transported material flowing on the belt conveyor, control is performed during a test operation before the belt conveyor is operated. The installation position of the device 4 may move for adjustment.

  IPv6 is the name of the next generation Internet protocol. The upper limit of the Internet protocol (IPv4) address of the 32-bit address system currently used is about 4.3 billion, and the shortage of addresses is getting serious with the rapid expansion of the Internet. Therefore, as the next generation specification of the Internet in which several functions are added to IPv4 by the IETF (Internet Engineering Task Force / Internet Technical Special Investigation Committee), 128 bits (address is 128 bits (about 3.4 × 10 38)). IPv6 that has been extended to a certain number) has been developed.

  Furthermore, in recent years, mobile IPv6 has attracted attention. In Mobile IPv6, MN (Mobile Node: mobile terminal: hereinafter simply referred to as MN), HA (Home Agent: home agent: hereinafter simply referred to as HA), CN (Correspondent Node: communication partner: hereinafter simply referred to as CN) There are three types of nodes. CN relays HA and connects with MN.

  In Mobile IPv6, the MN is assigned two types of addresses. These two types of addresses are an address on the network where the HA exists and an address that is automatically acquired after the movement. By setting these two types of IP addresses in the IP packet, communication can be performed without worrying about the IP address.

  In the embodiments shown in FIGS. 1, 3, 5, 7, and 9, the control device is replaced with MN and the relay device is replaced with HA. In the embodiments shown in FIGS. The data processing device is replaced with CN. That is, even when the control device is moved, the IP address is automatically assigned.

  As a result, the identification information of the moving object is read by the control device and the passage time is stored, and the position of the control device can be specified based on the passage time. Therefore, even when the position of the control device is changed, Collection is possible. Furthermore, since the IP address is automatically assigned even when the control device is moved by using mobile IPv6 for wireless communication, the man-hours required for network setting can be greatly reduced.
