DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an urban information network system in a small area centered on a portal post station.

[0002]

2. Description of the Related Art There was a time when it was considered that more information was better, but today when information is flooding, it is necessary to select necessary information for local residents. In addition, it is impossible for elderly people to try to obtain information using complicated tools. In general, in the metropolitan areas, local communities are being lost more and more, such as construction of large skyscrapers.

On the other hand, various security systems such as an automatic lock have been proposed as security systems for condominiums and the like in a metropolitan area. For example, a camera that moves up, down, left and right with a remote control and has an intercom with camera that allows you to check the outside while in the room, a keyless system that can be locked and unlocked just by pressing a password, an IC card For example, a card key system capable of locking and unlocking is installed.

[0004] However, these systems simply include the response of the entrance door of the room to the room or the response of the entrance door to the room, and are far from comprehensive management.

[0005] On the other hand, it is general that a guardman rushes by a report in a home security service provided by a security company, which is the most advanced method.

[0006]

However, according to this method, in a small lot area (radius of 100 m to 1000 m),
For example, if two or three incidents occur at the same time, the guard cars and guards located in that area go straight to the first accident site, contact the police and fire department at the site, and explain the current situation And so on.

[0007] Continuously at the second point in the report that the accident occurred,
When accidentally or planned again with the third point, a support car and security guard outside the area are required, and it takes quite a long time to reach the site, so there are cases where it arrives after a crime. As a result, planned crimes are getting worse. Therefore, a security network close to the community is needed.

[0008] An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to easily manage a building that does not have an existing management system. Management can be strengthened after occupants are stationed, management menus can be enhanced and human errors can be prevented, management costs can be reduced, and advanced systems can be introduced by utilizing the high-performance security system of existing core buildings. Cost-effectiveness can be obtained by distributing common information in the local area, arriving at the site a few minutes after cycling or walking a few minutes in the event of a disaster, and communicating with local SMEs by computerizing in a small area utilizing the characteristics of each area It is an object of the present invention to provide an urban information network system in a small area centered on a portal post station, which can be expected to lead to rehabilitation and distribution of information on residents' lives.

[0009]

In order to achieve the above object, the present invention firstly has a display screen and a computer function, and further has a PHS data communication unit, an IC card card reader, a modem function, and a gateway server function. For connecting digital devices such as PCs and fax machines (D
SU), a connection function (TA) for connecting analog devices to digital lines, a router, and a device connected to a TV camera for monitoring is installed as a portal post station at the entrance of each building, and one of the buildings Is equipped with a provider function as the core building of the area network center, and the portal post station of the building within a radius of 100 to 1,000 m from this core building and the portal post station of the core building are connected by wire or telephone so that they can communicate with the Internet. Second, the telephone line must be a digital subscriber line. Third, the security staff must have a mobile phone such as a PHS, and connect the mobile phone with a portal. Two-way communication with the post station and direct communication between visitors and others at the portal post station It is an Abstract that it has a possible communication was attached.

[0010] Fourth, when the building is an apartment, the display screen of the portal post station is an LCD touch panel that displays guidance at the time of key input and displays a key symbol required at that time. Fifth, an intercom for conversation with the intercom at the portal post station, an automatic door unlock button at the apartment entrance, an unlock button at the home entrance door, etc. A sub-terminal equipped with an operation panel and a monitor TV that receives and broadcasts video signals from a TV camera is installed in each room, and an alarm device that outputs to the portal post station and issues an alarm is installed in the room. It is assumed that.

According to the first aspect of the present invention, first,
As a point of contact between people living in large and small condominiums in the area, especially the point of contact between the elderly and young people, common management information on condominium buildings and emergency accidents occurred through the portal post station at the entrance of the building. At the same time, the portal post station at the entrance of the participating condominium / building in the small area area displays the location of the accident and its contents simultaneously with flashing lights, and displays the surrounding situation on the screen with a surveillance television camera. First-aid measures such as fire trucks, ambulances, guards, etc. are actually the most important. In this way, by displaying the surrounding situation on the screen at the portal post station, you can see this and see the neighborhood, neighborhood residents It is possible to take countermeasures by security officers and companies.

Second, it is possible to make the building management using the Internet unmanned. Stores measurement data of customer buildings via the “Building Management Data Information Site” network at the portal post station of the core building at the base station.
We can propose individual energy savings by processing. Remote control is possible by adjusting the alarm transmission of mechanical security, adjusting the temperature, humidity and air volume operation time of the air conditioner.

Third, an intranet within a company is positioned as a system that allows anyone to easily exchange high-level information and to share and utilize information anytime and anywhere. This is performed using a portal post station for each small area, for example, at the size of the neighborhood association, and an intranet of the neighborhood association (necessary for the local residents, which is specific to the area, is immediately provided).

Fourth, it is possible to support next-generation communication. At present, the interconnection of communication networks of different transmission systems is handled by converting optical signals into electrical signals once and performing various processing. However, devices are placed at the connection between the backbone communication network and the LAN, and optical TDM is installed. (Time division multiplexing) and optical WDM (wave table division multiplexing). The technology of interconnecting fiber optic networks also allows the adoption of a method for converting the optical signal to the desired format-the corresponding function is installed in the portal post station.

Fifth, by placing the portal post station in the entrance lobby of a condominium or commercial building (including an office building), it becomes a place for information exchange and chat between well-end conference-like neighborhood associations, offices of different types of business, and in-house employees. Can be used as a salon. If you can use the Internet simply by talking to the screen board, you will be able to use the Internet with the voice recognition software and the (portal) post station with ease of dialogue with middle-aged and elderly people. For example, if you say "Internet", "administrative association", "medical care", "living information", "direct information on childbirth" or the like, the related site appears on the screen. In other words, a usage method that enables two-way correspondence between the community-based information and the transmission place can be considered.

[0016] Sixth, if the portal post station users are allowed to use the site only for the users (treated as members) who have acquired the IC card except for the response of the visitors, the neighborhood residents (the neighborhood association) Function) can also join an IC card at actual cost only. In order to provide site locations for the portal post station, determine the fee burden based on the number of uses and the number of hours used in operation, and to make the selection of site programs of interest more attractive, an IC card payment function that pays points x unit price as operating costs will be provided. (Or members can use a mobile payment terminal)

According to the second aspect of the present invention, in addition to the above-described operation, D.E. S. L asymmetric digital subscriber line (ADS
L) has a speed of fetching data from the Internet ten times or more as compared with the integrated digital communication network (ISDN) of NTT.

According to the third aspect of the present invention, in addition to the above-described operation, when an accident occurs, a report can be sent directly to a mobile phone (with an e-mail function) of a security officer in charge (including during patrol).

When a monitoring device such as a television camera installed at the site detects an abnormality, it sends an alarm to a portal post station installed at the entrance of each building through a telephone line,
The portal post station has software that converts the alert information into electronic mail, and the email alert is delivered to a portal post station equipped with a provider function as a core building. The core building's portal post station sends the email to the security guard's mobile phone.

The time, place, and information on the occurrence of the accident are reported to the alarm mail. At the same time, it is also reported to the monitoring center. In order to grasp the information required for quick response in the security area, it is possible to search for necessary information and share information in the security area by combining a mobile phone and the Internet.

According to the fourth and fifth aspects of the present invention, as an alternative to the manager in the manager's room at the entrance such as an entrance, security is secured by restricting the persons who can enter the building to some extent. It alerts and displays the intruder from outside through the veranda and the fire entrance to the room to prevent intrusion, and also has a 24-hour night-time security function, and a security function. Separately, when a resident returns home, a message indicating the arrival of parcels delivered to the relevant person and a function linked with the parcel box facility, a function to display an emergency call in the elevator if an emergency call is made, etc. Can be demonstrated.

Automatic doors and terminals are installed at the entrance of the apartment to restrict the number of persons who can enter the apartment to some extent and to secure security inside the apartment. The person who can pass through the automatic door is limited to the resident of the apartment or the person approved by the resident of the apartment, and even if there is an intruder other than the authorized person, the visitor can be confirmed again at the home entrance .

In the case of a resident of an apartment, the limiting method and the confirming method are performed by using an IC card, a password, a visitor, an intercom, and an image of a television camera installed near the entrance of the terminal. Through these, security at the apartment and at the individual level is ensured.

Further, security sensors are installed near the veranda of each home and near the emergency stairs, and a warning is issued and displayed at the portal post station to an intruder from outside, thereby preventing the intruder. Further, even in the event of an emergency in the elevator, an alarm can be issued and displayed at the portal post station by providing an emergency transmitting device in the elevator, so that it can be dealt with.

The emergency transmission device in the elevator is a voice recognition device and / or a shock recognition device for an emergency. Therefore, even if an operation such as pressing a button by hand is not performed, a voice such as "help!" This is an outgoing call operation, which can be reliably performed even when dealing with darkness or robbery. Further, even when an impact is applied to the car due to an emergency stop or the like, the impact recognition device can detect this and make an emergency call.
