Description

The present invention relates to a location information system for confirming or tracking the location and movement route of people and objects.

Conventionally, a beacon system using BLE (Bluetooth Low Energy, Bluetooth is a registered trademark) that performs location information, location management, and flow line analysis of people and moving objects in a facility has been installed at a fixed location in the facility. ) device and a smartphone as the receiving (central) device.
This makes it easy to install by making the sending device that consumes less power intermittent operation battery-powered, and since it consumes a lot of power in a constant reception state, the receiving device can be repeatedly charged and connected to the Internet. This is because smartphones are convenient.
However, since the above system is based on the assumption that a smartphone is used and a dedicated application must be installed on the smartphone, it has been difficult to manage all the people who enter the facility.
In order to solve this problem, it is necessary to give the user an admission pass or the like in which the transmitting device is built in, and to use the permanently installed device on the facility side as the receiving side.
However, since the receiving side consumes a large amount of power as described above, it must be driven by a constant power supply, which requires occupying an AC outlet.

In order to overcome the problem that occupancy of AC outlets often becomes a problem in operation, if the receiving side equipment is built into LED lighting, which has become popular in recent years, a stable power supply will be supplied, no electrical work will be required, and fluorescent lamps will be replaced. Installation is possible only by exchanging.
For example, Japanese Patent Application Laid-Open No. 2017-212228 discloses a lighting fixture comprising a control device having a wireless tag in which a predetermined tag ID is written, and a lighting device attached to the control device,
A lighting fixture has been proposed in which the control device transmits a tag ID written in the wireless tag to the lighting device when the lighting device is attached to the control device.
However, in these conventional configurations, installation of the receiver requires opening a hole in the ceiling and wiring work for the AC power supply.
In addition, since the receiver is installed on the ceiling, the users of the facility may feel unsafe. "
Furthermore, by sending the detection information of people and objects from the receivers installed in each room, corridor, etc. in the facility to the server along with the receiver ID, it is possible to grasp where they are in the facility. It is necessary to register the ID and link the receiver ID to the facility map.
In other words, in the conventional system, installation of equipment requires workers with specialized skills and construction licenses. It had to be done by the seller.

9:15:31 2F-001
9:15:39 2F-004
9:15:44 2F-003
9:15:50 2F-002
9:15:58 2F-202
9:18:55 2F-002
9:19:01 2F-003
9:19:07 2F-004
9:19:48 2F-102 (warning)
9:20:11 2F-006
9:20:17 2F-004
9:20:21 2F-001

In this way, the flow line of the terminal ID can be tracked in real time, so for example, if the area to which 2F-102 belongs is set as a restricted area for T615, the tracking server 30 will detect that it is entering the restricted area. An alarm signal is sent to the computer unit 10 of 2F-102, and an alarm device (not shown) connected to the computer unit 10 sounds an alarm and turns on a warning light.
