Description

System and Method for Controlling Remotely Located Building Using Communication Device

The present invention relates to a system and a method for managing a building, such as a house, an apartment, or a building using a communication device, and more particularly, an owner of a building located at a remote location is connected to a door of a building using a wired or wireless communication device. The present invention relates to a system and method for controlling access of an installed interphone to manage access of external visitors.

The most common way to manage doors in houses, apartments, buildings, etc. (hereinafter referred to as buildings) is to use locks and keys. Locks and keys range from mechanical, the most classic form, to electronics such as the most advanced electronic locks and electronic keys with integrated circuits.

In particular, with the recent development of electronic technology, in general houses and apartments, integrated circuits that recognize passwords are built into locks so that even if a key is lost, the user can conveniently open and close the door. In large buildings, such as buildings that many people come and go, a card-type key (commonly called a "card key") that stores certain information is used to control access.

However, in the case where the above-described conventional mechanical and electronic lock and key (hereinafter, referred to as a lock) are installed in a door of a building, the owner directly couples the key (in the case of a mechanical lock) to a lock installed in the door or reads a predetermined reading. Only after work (in the case of an electronic lock) could access be made.

However, this conventional building management method has the following problems.

That is, when an outside visitor who does not have a key (mechanical or electronic key) visits, the problem is that the outside visitor cannot enter the building unless the manager or owner of the building is in or inside the building.

At this time, the external visitor may be largely divided into the following two classes. The first class is outside visitors who have no interest in the owner of the building, such as a merchandise salesman. They are third parties. The second group is outside visitors who have a stake in friends, family, or owners of the building. Can be.

If the owner of the building is external, that is, remote, it is not a problem as it is usually not necessary to respond to the first class of external visitors. However, if a second class of visitors visits, there is a possibility that a difficult situation may occur that prevents the user from entering the room. Of course, in these days when a mobile communication means such as a mobile phone is popularized, it is possible to talk directly to the owner of the building. However, even in this case, it is inconvenient that the external visitor still cannot enter the building until the owner arrives and opens the door.

For this reason, there is a demand for the construction of a system that enables the owner of a building to check external visitors and control their access even from a remote place far from the building.

In order to solve the above-mentioned problems of the prior art, the present invention is to provide a system and a method that can manage the entrance and exit of the building of the external visitors even in a remote place far from the building.

Another object of the present invention is to provide a system and method for controlling and managing access to a building from a remote location using wired or wireless communication technology.

It is still another object of the present invention to provide a building management system and method having a function of detecting when an external visitor wants to invade a building and notifying a building owner, a building manager, a police station, or the like by using wired or wireless communication technology. It is.

In order to achieve the above technical problem, the present invention system for managing the opening and closing of the building door using a communication device at a remote location far from the building,

Has an interphone installed in the building,

The interphone consists of a communication chip for transmitting a first signal to a communication device and receiving a second signal from the communication device, a microprocessor connected to the communication chip to transmit and receive the first and second signals, and a memory element connected to the microprocessor. The opening and closing of the building entrance door is controlled by the interphone remotely controlled by the communication device.

The method of the present invention for managing the opening and closing of the building door using a communication device at a remote location far from the building,

(a) operating the interphone installed in the building to transmit the first signal to the communication device,

(b) communicating with external visitors and building owners through intercoms and communication devices;

(c) transmitting a second signal from the communication device to a communication chip in the interphone;

(d) controlling the microprocessor in the interphone to control the opening and closing of the building door.

In the present invention, the first signal is the call number of the communication device, and the second signal is the call number of the communication chip in the interphone.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a block diagram for schematically illustrating a building management system of the present invention in which a building owner having a communication device can manage opening and closing of a building door even in a remote place using a communication network.

As shown, when an external visitor visits a building in which the system of the present invention is installed, the building owner 10 (a family of buildings, etc.) includes a communication chip, a microprocessor, and a memory device installed in the building using a communication device. By controlling the interphone, it is possible to control the opening and closing of the building door even at a remote location. In the present invention, a communication device is a concept including a wireless mobile phone, a wired phone, a computer (which can use an Internet phone), etc., capable of transmitting a call signal to a communication chip installed in the interphone. When the building owner 10 transmits a call number (generally a phone number) of the communication chip 30 using a communication device, the call number via the communication relay station 20 is transmitted to the communication chip 30 in the interphone. Is received. The called communication chip 30 is switched to the call mode, and the call mode of the communication chip 30 is recognized by the microprocessor 40. Thus, the building owner can transmit a specific control signal (eg, a signal to open the door) to his communication device, and the microprocessor 40 receives this control signal and performs a corresponding operation. As will be described later, the memory element 50 not only stores the information of the building owner but also pre-stores predetermined control signal information transmitted from the communication device of the building owner. In addition, the communication cable is connected to the outside, generally connected to the building manager, security company, or police station. Since the communication cable is connected to the microprocessor 40 to receive a predetermined control signal, remote control by a communication device is possible, and in some cases, the microprocessor 40 itself can also be controlled. The communication cable can also be used when the building owner wants to control and manage his building as a regular landline telephone (in this case, controlling the microprocessor 40 directly via the communication cable). This operation will be described later with reference to FIGS. 3 to 5.

Before explaining the operation sequence of the system of the present invention shown in FIG. 3, the conventional system shown in FIG. 2 will first be described in order to aid the conceptual understanding of the present invention.

Figure 2 is a simplified diagram of the operation sequence of a building access control system having a conventional electronic locking device in a flowchart.

In the drawing, step 200 is a step in which an electronic lock, a camera, a sensor, and the like are installed at a door of a building.

In step 201, an external visitor is located near a door or presses a bell or the like. In step 201, if the external visitor is within a certain distance from the door, the sensor detects this and enters step 202. Likewise, when an external visitor presses a bell installed at the door, step 202 is entered.

In step 202, if an external visitor holds an electronic (or in some cases mechanical) key, the door can be opened directly. You can open the door after checking. In this case, the state of the initial stage 200 is maintained via the stage 207 which is the reset stage indicating the end operation mode.

However, in step 202, if the electronic key used by the external visitor does not match the data (that is, the serial number) already input, a predetermined number of times of reconfirmation is performed. If the key does not match, the steps 203, 204, Step 205 may be executed selectively, sequentially or simultaneously. Here, step 203 is a step of transmitting an alarm signal to the owner of the building, the manager of the building, a private security company, or a police station, and step 204 is a step for threatening external visitors and obtaining evidence by operating an alarm or a camera. In operation 205, the voice sensor is operated to record a voice of an external visitor.

Whether the above steps are normally executed sequentially, selectively or simultaneously is determined at step 206. In the case of normal execution, the initial stage 200 is maintained via the reset stage 207. If not normally executed, steps 203 to 205 are re-executed sequentially, selectively or simultaneously.

The above has outlined the operation of the building management system using a conventional general electronic lock. However, such a conventional building management system has the following problems.

That is, in steps 201 and 202, when the external visitor does not have an electronic key or when nobody is in the room, there is no way for the external visitor to open the door.

The present invention provides a building management system that solves these problems raised in the conventional building management system.

Hereinafter, the building management system of the present invention will be described with reference to FIG.

First, step 300 represents a step in which an outside visitor presses the bell in front of the entrance of a building. For reference, even if the external visitor is located within the detection range of the sensor in step 300 has the same effect as pressing the bell.

Next, step 301 is to identify external visitors. For reference, in the present invention, the step of identifying an external visitor is based on assuming that there are no people indoors, that is, there is a building owner in a remote place (when there are people in the room, there is no difference from the conventional case). Description is omitted).

A specific example of step 301 of identifying external visitors is shown in FIG. 4. As will be described in detail with reference to FIG. 4, the external visitor identification step of step 301 is performed by a communication technique. That is, a building owner who receives a call signal from a wireless communication device embedded in an interphone that is triggered by a sensor or a bell signal and transmits the call signal to a communication device (for example, a landline phone or a mobile phone) of the building owner. Performs a predetermined procedure using its communication device that receives the call signal. In this case, the predetermined procedure refers to a call with an external visitor who pressed the bell of the interphone to confirm its identity, and when the external visitor is a guest, it is programmed by a small microprocessor 40 and a memory element 50 embedded in the interphone of the building. Means to perform the procedure to open the door by sequentially executing the process, which is described in detail in FIG.

Next, step 303 is a step in which the owner of a building located at a remote site performs an external visitor identification process in step 302, and then opens a door using the building owner's own communication device. Is the step to perform the function as well. When step 303 is completed, all situations are terminated (step 305) and the system returns to step 300 which is in the initial state. However, if it is determined that the external visitor is not a normal visitor while performing the external visitor verification process of step 301, after a predetermined time elapses (for example, when an outsider who is determined to be an intruder lingers there) Step 304 is performed by performing a predetermined procedure. In step 304, an alarm signal is sent to a management office or a police station, and a surveillance camera or the like is operated.

As can be seen in the description of FIG. 3, the building owner can communicate with an external visitor who visited his building using a communication device even when he is not indoors, that is, in a remote location, and checks the external visitor. You can open the door or let go of your absence.

FIG. 4 specifically illustrates an operation process performed in step 301 of FIG. 3.

In Figure 4, the transmitter means a communication device of the building owner, the remote control means another communication device that is connected to the intercom of the building and can transmit and receive signals with the communication device of the building owner. The remote control unit stores a communication chip 30 capable of transmitting and receiving a telephone number (in the present invention, a CDMA chip for wireless communication), a memory device 50 storing a telephone number, and the like, and a telephone number to be transmitted and received. It basically includes a microprocessor 40 having a function of comparing with the phone number stored in the basic, as well as further includes an external interphone installed in the vicinity of the door and an internal interphone connected to the room installed therein. The communication chip 30, the microprocessor 40, and the memory device 50 may be installed in one of an internal interphone or an external interphone. Interphones used without special mention in this specification refer to external interphones, but in practice these configuration means are not significantly different wherever installed in the internal and external interphones. Therefore, the remote control unit described with reference to FIG. 4 may be understood as virtually the same as an interphone installed outside.

In connection with the operation, when the external visitor presses the bell, the remote control is operated. That is, when a bell signal is applied, the communication device number of the building owner stored in the memory device 50 is read by the control of the microprocessor 40, and the read phone number is a communication chip capable of transmitting and receiving a phone number. It is input to 30. The microprocessor 40 transmits a control command to the communication chip 30 to transmit the telephone number input to the communication chip 30. As a result, the communication chip 30 performs an operation of calling the owner's communication device, and step 400 of FIG. 4 illustrates this operation.

The owner of the building, which receives the call of step 400, makes a call with an external visitor. That is, the external visitor can talk to the building owner at a remote location through the intercom, and the building owner can talk to the external visitor using his or her communication device such as a mobile phone.

If the result of a call with an external visitor is that the door should be opened, ask the external visitor to wait for a while and disconnect the communication device.

After ending the call with the external visitor, the building owner again calls the telephone number of the communication chip 30 stored in the remote control unit with his communication device. This step is step 401.

The remote control checks whether the telephone number of the calling communication device calling the telephone number of the communication chip 30 is the same as the telephone number of the building owner. If the telephone number of the calling communication device is the same as the phone number of the building owner, the communication chip 30 enters a busy state, and sends an acknowledgment signal for the call of step 401 to the calling unit (step 402). The reason for this check is to prevent unauthorized access to the remote control of the building owner by anyone other than the building owner.

The building owner then enters the user ID and sends it to the remote control (step 403). In general, a user ID transmitted to a remote control unit is transmitted in a DTMF signal. The remote control confirms the user ID and transmits the result of the verification to the transmitter as a DTMF signal or an ARS automatic voice service signal (step 404). The reason for the user ID verification process is to prevent unauthorized access to the remote control unit by a communication device of the building owner other than the building owner.

If a normal user ID is input and the verification process is completed, the remote controller can be controlled. That is, the control of the microprocessor 40 as part of the contents stored in the memory device of the remote controller to input a predetermined control code for performing a specific operation by the ARS automatic voice service signal in step 404. The owner of the building, which has been sent through the communication chip 30, sends the predetermined control code to the remote controller (step 405).

The remote controller checks the control code received through the communication chip 30 with the control code previously stored in the memory and generates a predetermined control signal. This process is performed by the microprocessor 40. The remote controller checks the status of the operation processed by the control signal and sends the result to the transmitter as a DTMF signal or an ARS automatic voice service signal, as well as an automatic voice service for inputting an additional control code (step 406). ).

For example, the process of steps 405 and 406 will be described below.

Sender:

Enter 1234 # (eg, a control code number to open the door).

Remote control:

1234 Receive and verify the contents of 1234 stored in the memory device 50.

Microprocessor 40 generates a control signal to open the door.

-The microprocessor 40 checks the situation (when the door is opened).

Send a signal to the calling station that the door is normally open (send an automatic voice service to enter the control code for further action).

Sender:

-Receive operation completion signal.

Input a control code corresponding thereto to change the user ID or terminate the operation (substantially repeating steps 305 and 306).

If there is no additional operation, the building owner sends out a control code corresponding to the termination signal to the remote control unit to terminate the operation of the system (step 407). When the operation ends, the entire system remains in an initialized state.

3 and 4, when using the building management system of the present invention, even if the building owner is in a remote location, it is possible to check the external visitors, as well as to remotely open the door if necessary. Able to know.

In the present invention, the interphone installed near the entrance of the building basically includes a bell signal reception function, a video function, and an alarm function, which are usually used for the interphone.

In the present invention, the building owner is controlling the door of the building in the remote place using a wired telephone or a mobile phone, but also of course, it is also possible to control via the Internet or IMT-2000 capable of video communication. Using the IMT-2000 to control the remote control has the advantage of observing external visitors.

In the present invention, in the example of the present invention described in steps 400 and 401 of FIG. 4, after ending a call with an external visitor, the remote controller is controlled starting with step 401. Therefore, it was not possible to talk to external visitors while controlling the remote control. However, as another example of the present invention, by connecting the communication chip 30 in the remote control unit with the interphone, it is also possible to build a system that can communicate with an external visitor while controlling the remote control unit if necessary.

The remote building management system of the present invention described so far relates to operation when the building owner is not in the building (more specifically, indoor) (operation of the present invention system when the building owner is indoors). This prevents the interphone signal from being transmitted to the building owner's communication device (for example, a mobile phone) unnecessarily. That is, when the building owner goes out of the building, the building owner switches the operation mode of the system to the outgoing state so that the signal of the interphone can be received by the communication device.

The present invention described above has no inconvenience when applied to a management system and a management method for a building. However, if the present systems are built in a large building of a certain size or more, such as an apartment, a multi-row apartment building, or a building with a large number of offices, there is a need for a management office to manage them effectively.

5 is for explaining how to effectively manage individual buildings in a management center, such as a large apartment equipped with the present invention system.

In Fig. 5, the systems of the present invention, which are built in individual buildings constituting a large-scale apartment or the like, are connected to a management station by a communication network (for example, a LAN). The station can determine whether or not there is a person in each building by managing a computer or an electronic board connected to this communication network (in the drawing, the hatched area indicates the outing mode).

As an example, if there is a person in building A and no person in building B, look at how the present system is applied. Since there is a person in building A, the operation of the present invention system installed in building A will be blocked. Therefore, an indication that a person is present in the computer or electronic dashboard of the station. However, since there is no person in the building B, the operation mode of the system of the present invention installed in the building B will be switched out (normal operation of the system of the present invention). Therefore, there may be an indication that there is no person in the station computer or electronic status board. As a result, it is possible to perform the management work efficiently by periodically observing or managing individual buildings marked as no people at the station. For example, a station can manage a whole building in a short time by operating a camera installed near the entrance of each building through a computer connected to a communication network.

As can be seen from the above, the present invention system can be applied not only to individual houses, but also to large-scale apartments or buildings composed of many offices, and, if there is a management station of the building, the entire building can be efficiently managed.

In addition, although not mentioned above, when the door is open for a predetermined time such as the door is not completely closed, the present system automatically sends an alarm signal to the communication device of the building owner and simultaneously operates a camera installed near the door. In addition, the station can detect this and perform special management. Eventually, building owners will be able to manage their buildings efficiently from remote locations.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, the remote building management system of the present invention, because the building owner can control the opening and closing of the building door at a remote location, it can cope with the case of unexpected visitor, and the remote control system for home automation It can be sufficiently applied even when constructing a.
