Thus, in the center device 1, when there is a user of the room R in the room R, the security alert is released, so that there is no false alarm, and when the user of the room R goes out, the security alert is automatically given. Can be set dynamically.

Further, the center device 1 monitors the operation state of each facility, monitoring of security alarms and the like as shown in FIG. 6, and when the user leaves the room without closing the door, the center device is monitored. The electric lock was locked remotely from 1.

[0008]

However, the ID reading device stores a large number of IDs and performs collation and unlocking operations, and the ID data is registered and deleted from the center device 1 and managed. ing. Therefore, there is a problem that as the storage amount of the ID is larger, it takes more time to register and delete the ID in the ID reading device, which hinders the communication with the center device 1. This will be described below.

FIG. 7 shows the processing between the center device 1 and the ID reading device when the registration of the ID is deleted. Here, a case where, for example, there are ten new ID registrations will be described. The center device 1 transmits the first newly registered item as shown in FIG.
The (card reader A) completes after the time T1 required for the registration process and returns a confirmation signal ACK to the center device 1.
Then, the center device 1 transmits the second new registration as shown in FIG. 7C, and the ID reading device 2 completes after the time T1 required for the registration process and returns a confirmation signal ACK to the center device 1. . Thereafter, the tenth newly registered item is transmitted as shown in FIG. 7 (d), and the ID reader 2 completes the registration process after the time T1 required for the registration process, and receives the confirmation signal AC.
K is returned to the center device 1.

Next, as shown in FIG. 7 (e), the center device 1 transmits the first newly registered item to the ID reader 2 (card reader B), and the ID reader 2 (card reader B) performs registration processing. After the completion of the time T1, the confirmation signal AC
K is returned to the center device 1. The following is a repetition of this. FIG. 8 is a flowchart summarizing the above-described procedure. As a countermeasure for this, conventionally, the time for waiting for the next transmission in the center apparatus 1 has been compensated by extending the time, but there has been a problem that the processing time of the entire system becomes slow.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to use a communication line efficiently and to set a communication interval according to the processing capability of a terminal. An object of the present invention is to provide an excellent entry / exit management system that can make a terminal device inexpensive.
