The patrol DB 73 is a table for storing patrol information generated as shown in FIG. 4 and includes fields related to a PPA serial number, card serial number, patrol date, month, date and time, security code, status, and patrol share number. .

The smart card DB 75 defines fields for a smart card serial number, an installation address, an installation location (such as a wall, a wall, a pillar), an installation date, and the like.

The state DB 77 is a table for storing and retrieving only a state that is particularly abnormal during a state of patrol. For example, data such as non-patrol, patrol information error, card damage, card loss, and the like are stored together with the corresponding date and time.

6 is a system structural diagram showing a state where a plurality of client computers 80 according to the present invention are connected to a central server device 90 via a network 82. As shown in Fig. 6, the client computer 80 in each police box is connected to the central server device 90 through a network 82 such as the Internet, a leased line, or a dedicated administrative network.

In one embodiment of the present invention, when the wireless communication modem 48 is any one of a Bluetooth communication module and an infrared communication module, the information of the mobile terminal 40 is stored in the client computer 80-> network 82-> server device. If the wireless communication modem 48 is one of a CDMA communication module and a wireless LAN communication module, the information of the mobile terminal 40 is transmitted to the public backbone network-> mobile communication company server-> network->. It is transmitted to the server device 90.

The server device 90 receives the patrol information in real time or every predetermined period from the client computer 80 installed in the police box distributed in each region (for example, the entire city in Seoul) and stores it in a separate database. This database has a structure similar to that of the database device 70 shown in FIG.

Hereinafter, the operation of the patrol information management device using the smart card and the portable terminal having the above configuration will be described in detail.

First, in the preparation step of the patrol, the patrolman receives the portable terminal 40, enters its own unique number through the key input unit 43 and stores it in the memory 47.

Then, the first patrol place 10a of the determined patrol place arrives and checks the mark of the location where the smart card 20 is embedded. Then, the mobile terminal 40 is approached in the range of 1 cm to 10 cm. At this time, the passive RF unit 44 transmits a carrier wave, and the unique number of the smart card 20 is demodulated and reflected on the transmitted carrier wave.

Then, the CPU 41 checks the patrol information as shown in FIG. 4 based on the received unique number of the smart card 20, the current time from the clock 45, the patrol unique number stored in the memory 47, and the like. Save it. When the storage is completed and processed normally, " status " data is inputted as " normal ", and the relief 49 is set to output a normal process confirmation sound. In addition, the CPU 41 displays character information such as "processing completed", "normal processing" or "OK" through the LCD 46.

After the patrol hears the normal processing confirmation sound, it moves to the next patrol place 10b and repeats the above process. Through such an iterative process, patrol information is stored in the mobile terminal 40.

Hereinafter, a process of processing patrol information generated as described above and stored in the mobile terminal 40 by the client computer 80 and the server device 90 will be described in detail.

After the patrol process ends, the patrolman returns to the police box and connects his portable terminal 40 with the client computer 80. In this case, the USB terminal may be used in the case of a wired line, and in the case of a wireless line, the USB terminal may be positioned near the Bluetooth communication module or the infrared communication module.

The stored patrol information is stored in the database device 70 of the client computer 80. Then, it is transmitted from the client computer 80 to the server device 90 via the network 82 and stored.

In the present invention, as another embodiment of the wireless communication modem 48, when adopting a CDMA module or a wireless LAN module, patrol information generated at each patrol place 10 is a server in real time through a relay system of a mobile communication company. Stored in device 90. The patrol information stored in the server device 90 is searched for each corresponding police box again and downloaded to each client computer 80 through the network 82. Therefore, each police box can determine whether patrol is normally performed in the jurisdiction through its client computer 80.

In this embodiment, the passive method used for the RF communication is a frequency of 5.8GHz, the channel interval is 5MHz, and the modulation and demodulation method uses the ASK method when transmitted (downlink) and the PSK method when reflected (uplink). However, other 2.4GHz, 900MHz, and 480MHz bands can be replaced.

In the present invention, the police system of the police box is shown and described mainly, but the present invention is not limited thereto, and may be widely used in the fields of security, military security, schools, government offices, factories, and the like.

In addition, it can be utilized not only for patrol, security purposes, but also for maintenance of facilities, systems, and cleaning services.

The system of the present invention can be implemented as a series of instructions that can be read and executed by a computer, which instructions can be recorded on a record carrier. Examples of such a recording medium include a hard disk, a RAM device, a ROM device, a compact disk, a DVD, a CD-ROM, a magneto-optical disk, a floppy disk, a digital tape, a memory stick, and the like.

According to the patrol information management device using a smart card and a portable terminal as described above, by embedding a smart card in each patrol area, it is possible to accurately determine the patrol time because the data is recorded at the point of patrol. In addition, by integrated management of the relevant patrol data, there is an economical ability to significantly reduce the management cost and manpower related to the patrol business.

In addition, by centrally managing the patrol service in the wide area patrol area through the network, it is possible to share the work of each police box or police station, and to give systematic instructions on this.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
