Abstract

PURPOSE:To attain two-way radio communication for lots of TRCs and to attain quick response to a required specific TRC by applying two-way radio transmission communication between a fixed side radio equipment and a transponding card with a radio transmission/reception function to an IC card. CONSTITUTION:A local radio control equipment LRC 3 gives a polling signal for reply to each transponding card TRC via each radio equipment TRT 6 at every prescribed time T. The TRT 6 applies the radio detection of each TRC 8 (by number of TRCs being transmission and reception object number) at a time being nearly equal division of the prescribed timer T by the transmission/reception object TRC number, that is, M/N, where M is the maximum TRC number and N is number of groups. When the radio detection comes from a TRC 8, it is informed to a central radio control equipment CRC 4 from the LRC 3 via a transmission line 2 and its location, time and notice information from the TRC 8 are stored in a memory 5 in the CRC 4. When the data read request exists from a center 1, the data is read from the memory 5 by the CRC 4 and the result is sent to the center 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wireless transmission communication system using an IC card (transbonding card) having a wireless transmission/reception function.

(Conventional Technology) Recently, intelligent buildings and hotels that have both advanced information communication functions and building management functions have been constructed.

It is desirable that many users of these facilities be able to work efficiently, comfortably, and safely, thereby increasing the functionality of the facilities themselves and making them more attractive to users. For this reason, it is essential to promptly and accurately notify users of the facility in the event of an emergency.

By the way, in the case of a conventional transponder having a detection function using radio waves or a wireless function, (1) a specific transponder is detected;

(2) Send a message or the like to a specific transponder to provide one-way notification to the transponder holder.

This is becoming possible.

(Problems to be Solved by the Invention) However, the device with the above configuration only specifies a target transponder and unidirectionally notifies a specific transponder.

However, despite the need to simultaneously send and receive information to and from a large number of transponders during emergencies, it has not yet been possible to simultaneously send and receive information from many transponders. Not yet.

In view of this situation, the present invention provides a communication system for a transbonding device that can simultaneously send and receive information to and from a large number of transponders, and can also send and receive information to a specific transponder immediately. The purpose is to provide a method.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides communication by bidirectional wireless transmission between a transbonding card, which is an IC card with a wireless transmission/reception function, and a fixed-side radio device. (Function) According to the present invention, personal identification information (ID code, etc.), location information, time information, etc. are transmitted to a radio device by inputting from a transbonding card attached to a moving object. do. In addition, all transformer bonding cards and specific transformer bonding cards F' (
TRC group), transmits a response request signal, responds to each detected TRC within a fixed time, and transmits response data if there is response data. It is something.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The first rffl is an overall configuration diagram of a communication system of a transbonding device according to the present invention.

In the figure, numeral 1 is a center provided on the fixed side in which a computer is installed, and a file 1-1, a data terminal 1-2, etc. are connected to this center 1.

2 is a transmission line such as a LAN (low power area network), and this transmission line 2 has a local radio station 1 -
r:1-le device '1j (1, RC) 3 and central non-cotton control device 4 are connected. This CRC4 is
It has built-in memory 5, etc. Reference numeral 6 denotes a radio device (TPT), which is installed at various locations in the facility or inside the building, and can perform wireless communication with the transbonding card via the antenna 7. 8 is a transbonding card (TRC), which is worn by a person and enables wireless communication with the TPT 6.

Here, as shown in FIG. 2, the TRC 8 is an IC card having a wireless transmission/reception function and has a transmission/reception section 8-1. 3. It has a display section 8-4, a key power section 8-5, a clock section 8-6, etc., and personal identification information (ID code, etc.), location information, time, etc. are displayed by inputting the key power section 8-5. Information, input data (button type, numeric keypad numeric data, etc.)
In addition, data within the TRC can be transmitted to a wireless device on the fixed station side.

Next, an application example of this communication method will be explained.

First, L and RC3 issue a polling signal to each TRC via each TRT6 at fixed time intervals T, and seek a response. TPT6 divides this constant time T into the number of TRCs to be transmitted and received, that is, the maximum number of TRCs M divided into N groups, approximately equally divided by M/N, t i = CT/ (M/N)) - α (i = 1, 2.
..., M/N>, radio detection is performed for each TRC8 (as many as the number of TRCs to be transmitted and received).

Therefore, if there is a radio detection from TRC8, L, R
Transmission line 2 from C3 via T: CRC4 ni+m,
The location, time, notification information from TRC8, etc. are CRC
It is stored in the memory 5 in J. When there is a request to read this data from the center 1 or the like, the CRC 4 reads the data from the memory 5 and transfers it to the center 1.

Next, a specific application example for performing the above operation will be described.

FIG. 3 is a diagram of the logical structure between LRC and CRC.

In the figure, 11 is an upper interface connected to the center 1, 12 is a first data processing unit, 13 is a second data processing unit, 14 is a lower interface via a transmission path such as a LAN, and 15 is an interface for each LRC. This is the verification logic.

As mentioned above, the location, time, and notification information from the TRC8 are recorded in the CRC4 for the rRC8 where the radio was detected.
The TRC1 data structure* to be stored in the memory 5 is as shown in FIG. 3(b). That is, starting with TRC address 21, location information 22, time information 23, personal identification information (In code) 24.1'RC
Input data (manual data from il+, numeric keypad, sensor, etc.)25, TRC output data (buzzer, lamp,
(Manual data for L E D character display) 26, others 27
is provided.

FIG. 4 is a time chart showing an embodiment of wireless communication according to the present invention.

Here, this example is carried out under the following conditions.

(a) The maximum number of TRCs handled by a wireless transceiver is 1920, (
b) Number of S line devices i; I: 250, (C) Maximum number of TRCs, 1920, divided into 4 groups,
Send and receive at regular intervals.

(d) All 1920 TRCs are sequentially detected wirelessly in one minute.

As shown in Fig. 4, a position identification signal ■ and a polling signal ■ are issued, and 8 x 4 groups of TRs respond to them.
C's polling response is made at time t3, for example, 1 second. In this way, polling and response exchanges are performed sequentially with "Z+L3+...t60. At this time, frame J9 of the position identification signal ■ and polling signal ■ consists of the data string shown in the figure, and each of these Radio (2)
50 units). Note that the polling signal specifies a sequential response for all TRCs, and specifies a specific TRC.
It is classified into random response designation for T and individual TRC designation. Also, polling responses are allocated within one second as shown in the table of FIG. In addition, the above-mentioned times T, t
i (+ = 1.2...) can be shortened as appropriate. For example, if there is no response to the random response designation polling, the polling response is sequentially designated in the order shown in the table of FIG. 4, and a response corresponding to the polling is made. If there is a polling response for lamp J, there is no TRC response for the sequential response at that time.

For example, in places where a large number of users are active within a certain area, such as an intelligent building, each user can be equipped with a transbonding cart and can communicate wirelessly with a fixed wireless device. . especially,
Through input operations from the TRC, it is possible to transmit TIC codes, location information, time information, human data, and other TRC data to the fixed side, and from the fixed side radio, all TRC and A response request signal is sent to a specific TRC (TRC group), and each 'T'
The RC responds within a fixed time and, if there is response data, transmits the response data. For example, when this communication system is applied to an intelligent building control system J, it is possible to perform various controls such as electric heater control, air conditioning control, lighting control, etc. without specifying the TRC holder and knowing the number of people. I can do it.

(2) It can be used for guidance, communication, etc., such as in-building calls, in-building guidance, and congestion situation notifications for an unspecified number of people.

(3) It can be used for targeting specific people, etc.

(4) The light, thin, short, and small card-shaped transbonding card is easy to attach to the user. It can also be configured to serve as a name plate.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

(Effects of the Invention) As described in detail above, according to the present invention, the present invention includes a radio device provided on a fixed side and a transbonding card mounted on a moving body, and an interface between the radio device and the transbonding card. Since it is possible to perform bidirectional wireless transmission and reception, it is possible to perform bidirectional wireless communication targeting a large number of TRCs, and to quickly respond to a necessary specific TRC. In addition, the miniaturized transbonding card does not feel strange and is difficult to install. Therefore, when the IM borrowing system of the present invention is adopted in intelligent buildings, hotels, etc., users will be provided with a comfortable and safe environment.
