CONSTITUTION:The system is provided with a radio equipment 70 able to process plural reply frequencies installed at a stationary side and plural kinds of TRCs 91, 92 having a single transmission frequency communicating with the radio equipment able to process plural reply frequencies and having different transmission frequencies in one and same time slot. Position information from an infrared ray transmitter ITX 63 is sent to the TRCs 91, 92, and received by an infrared ray receiver IRX 82 via a light receiving face 80 and fetched by a microcomputer MPU 81. Then information such as an ID code is added to the position information and the result is sent to the radio equipment TRT 70. In this case, the TRC 91 sends a transmission frequency f1 and the TRC 92 sends a transmission frequency f2 and the respective information is received by the radio equipment TRT 70. Thus, the processing capability of the TRC is increased.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a wireless transmission communication system using an IC card (transbonding card) having a wireless transmission/reception function, and particularly to a method for increasing the processing capacity of the transbonding card. Regarding.

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

In these facilities, it is desirable for many users to be able to work efficiently, comfortably, and safely, thereby increasing the functionality of the facilities themselves and making them more attractive to users.

From that meaning, v! In the event of an emergency, it is essential that users within the facility be notified promptly and accurately.

In view of this situation, the applicant of this patent has already developed a communication system for transbonding equipment (Japanese Patent Laid-Open No. 62-269
(See No. 50).

FIG. 6 is an overall configuration diagram of a communication system of such a conventional transbonding device.

In the figure, l is a management center equipped with a computer installed on the fixed side, and this management center l has a file l-
1, data terminal 1-2, etc. are connected. 2 is LAN
(local area network), etc.,
This transmission line 2 has a local radio control device 7LR.
c3 and a central radio control device CRC4 having a built-in memory 5 are connected thereto. Reference numeral 6 denotes a wireless device TPT, which is installed at various locations in the facility or premises, and can perform wireless communication with the transbonding card TRC 8 via the antenna 7. This TRC8 can be worn by people to perform TRT.
This enables wireless communication with 6.

Here, the TRC 8 is an IC card equipped with a transmitter/receiver section 8-1 having a wireless transmitter/receiver function, as shown in FIG. This TRC 8 also includes a 'M control section 8-2, a memory 8-3, a display section 8-4, a key manual section 8-5, and a clock section 8-2.
6. It has a built-in power supply section 8-7, etc., and the key human power section 8-7.
Personal identification information ([D code etc.],
Position information, time information, input data (dark blue type, numeric keypad data, etc.) and other data within the TRC can be transmitted to the fixed station radio.

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

First, the LRC 3 issues a polling signal to each TRC via each TPT 6 at fixed time intervals T, and requests a response. TRT6 divides this fixed special period 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, t4, that is, LL = (T/ (M/N)) - Radio detection is performed for each TRC8 (the number of TRCs to be transmitted and received) within α (, = 1.2. . . . , M/N).

Therefore, if there is a radio detection from TRC8, LRC3
The CRC 4 is notified via the transmission path 2, and the location, time, notification information from the TRC 8, etc. are stored in the memory 5 within the CRC. Further, when there is a request to read this data from the management center 1, etc., the CRC 4 reads the pig from the memory 5 and transfers it to the management center 1.

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

FIG. 8 is a diagram showing the logical structure between the LRC and CRC.

In FIG. 8(a), 11 is an upper interface connected to the management center 1, 12 is a second data processing unit, 13 is a second data processing unit, and 14 is a lower interface connected to a transmission path such as a LAN. , 15 is a verification logic for each LRC, and the other configurations are the same as those in FIG. 6 above.

As mentioned above, for TRC8 where radio detection occurred,
Its location, special rules, and notification information are stored in the memory 5 of its CRC4.
The TRC data structure is as shown in FIG. 8(b). That is, T.R.
Starting with C address 21, location information 22, time information 23
, personal identification information (ID code) 24, TRC input data (input data from iD, numeric keypad, sensor, etc.) 25
, TRC output data (buzzer, lamp, input data to LED character display) 26, and others 27 are provided.

FIG. 9 is a timer diagram showing an example of the wireless communication.
It is 1.

Here, the wireless communication system in this embodiment is implemented under the following conditions.

(a) The maximum number of TRCs handled by a wireless transceiver is 1920, (
b) The number of fivAa is 250, and (c) The number of II large TRC is 1920, divided into 4 groups and sent and received at regular intervals.

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

As shown in FIG. 9, when the position identification signal and the polling signal (2) are issued, polling responses (2) of 8×4 groups of TRCs are made in response to the position identification signal and the polling signal (2) in a time period of 7, for example, 1 second. In this way, 1. ．． 13. ...t.

Polling and response exchanges are performed. and,
The frames of the position identification signal ■ and polling signal ■ at this time are determined from the data string shown in the figure, and these are
(250 units). Note that the polling signal (■) can be used to specify sequential responses for all TRCs, random responses for specific TRTs, and individual TRCs.
Classified according to specifications. Also, the polling response ■ is 1
Although the time is allocated within seconds as shown in the table of FIG. 9, the above-mentioned time T, that is, t, (,=1°2, . . . ) can be shortened as appropriate. Here, for example, if there is no response to random response designation polling, sequential designation is performed in the order shown in the table in Figure 9, and a response corresponding to the polling is performed.In addition, if there is a random polling response ■ is the TR of the sequential response at that time
C No response.

Furthermore, in order to improve the position recognition accuracy of such a communication system, the applicant of the present patent has further proposed a data communication system (see Japanese Patent Application No. 107814/1983) that uses a combination of infrared rays and radio waves.

That is, FIG. 10 is a configuration diagram of such a conventional data communication system using a combination of infrared rays and radio waves, in which a portable transbonding card is attached to a moving object and the position of the moving object is detected. . Figure 11 shows the constituent countries of the transbonding card.

In addition, the transbonding card 50 individually stores individual recognition information such as an ID code, additional information required by the system, etc., and attaches this transbonding card to a moving object such as an animal or a human to be managed.
