The controller 11 may set various functions by the remote controller, and the remote controller may communicate with the controller 11 in a ZigBee manner.

3 is a flowchart illustrating a process of generating an event in the control device according to the present invention.

First, the control device according to the present invention receives a specific event (102) in the standby state (101). The event may be generated by various sensors, by a management system, or by a remote controller or a keypad.

When an event occurs, the controller 11 checks the event content (103). If the generated event is a mode setting (104), change the current mode state to the requested mode state and set (105). The mode includes an outing mode, a sleep mode, and a basic mode. The mode may be changed by a user by accessing a management system using a computer or a mobile phone, or may be changed through a remote controller or a keypad. The outing mode and the sleep mode are applied from 1 minute after the mode setting, and the basic mode is applied immediately after the mode setting.

In the process of changing and setting the mode of the control device at a remote location, the subscriber accesses the management system using a personal computer or a mobile phone. And enter their ID and password, subscriber authentication is performed. If the authentication is successful, the management system provides a menu for service selection, and the subscriber requests to change the mode of the control apparatus through the provided menu. Then, the management system generates a message for controlling the control device of the subscriber, and transmits a mode change control message to the control device. The control device changes its mode according to the mode change control message sent from the management system.

On the other hand, if the generated event is an event caused by gas or fire, the process is performed accordingly (106). This is as follows.

If a gas leak or fire is detected by a gas monitoring sensor or fire detection sensor, the control unit immediately generates an alarm, shuts off the gas, and turns on the light. In addition, the current mode is checked, and when the camera is in the outing mode or in the sleep mode, the image of the situation on the spot and the contents of the generated event (for example, whether it is a fire or a gas leak) are transmitted to the management system.

When the management system receives the contents of the event and the captured video information from the control device, the management system first checks the subscriber information by referring to the IP of the control device. Then, the transmitted image is stored in the subscriber area of the database, and at the same time, after confirming the contents of the event, a short message for notifying the subscriber of the event occurrence is constructed and transmitted to the mobile phone of the subscriber. The short message includes the content and time of occurrence of the event, and a callback URL for direct access to the management system. In this case, the management system transmits the short message to at least two mobile phones stored in the subscriber information in transmitting the short message.

On the other hand, if the generated event is an event related to the environment is processed through the following process (108).

First, the subscriber sets whether to perform automatic control in relation to the environment in the control apparatus. Environmental monitors measure and transmit environmental data related to temperature, humidity and air pollution in the home to the control unit. The control device receives environmental data and, in the case of automatic control, operates electronic devices such as a humidifier, an air purifier, a boiler, and an air conditioner to optimally maintain the environment in the home. In addition, the control unit transmits the input environmental data to the management system. Such environmental data is periodically transmitted to and stored in the management system. The management system stores the environmental data and notifies the subscriber's mobile phone in a short message if the criteria is exceeded. The subscriber can access the management system via a mobile phone or computer to change the automatic control setting of the control device.

When the generated event is a real-time monitoring 109 is processed through the following process.

Real time monitoring is required from the management system. That is, when the subscriber accesses the management system and requests real time monitoring, the management system checks the IP of the corresponding control device through the subscriber information and then requests the real time monitoring by the control device. Then, the controller controls the network camera to take an image, and the captured image is transmitted to the subscriber's mobile phone through the management system.

On the other hand, if the generated event is intrusion monitoring is processed in the process as shown in Figure 4 (107).

If an illegal intrusion is detected through the magnetic sensor or the fuselage monitoring sensor, the control unit checks the current setting mode (201). If the setting mode is the basic mode, the state transitions back to the standby state (202).

If the setting mode is out, the camera is turned on immediately and a picture is taken (203). It waits for a predetermined time (preferably 30 seconds) (204). The waiting time is for giving a time for the occupant who enters the house to release the intrusion monitoring state through a password input or the like, and the waiting time may be arbitrarily set by the subscriber. When the intrusion monitoring state is released (205) from the waiting state for a predetermined time, the state transitions to the waiting state (202). If the intrusion monitoring state is not released even after waiting for a predetermined time (205), the control device regards it as an illegal intrusion, generates an alarm sound and simultaneously transmits the event occurrence and the captured image to the management system (206 and 207).

When the intrusion monitoring event occurs in the outgoing mode, the management system uses the IP of the control device to check subscriber information, store captured images in the area, and records the event with at least two subscriber mobile phones already stored in the database. Send a short message containing the time of occurrence and a callback URL to connect to the management system. The subscriber can access the management system to check the stored video or to check the current situation inside the house in real time.

On the other hand, when the setting mode is the sleep mode, the control device turns on the light immediately, generates an alarm sound immediately without waiting time, and takes a picture. The captured image is transmitted to the management system. The management system does not send a short message to the subscriber's mobile phone in sleep mode.

On the other hand, when an event occurs, the control device takes five pictures in succession and transmits the pictures to the management system. The management system stores the pictures sent from the control device by subscribers, and the maximum storage period is one week.

5 is a flowchart for explaining a processing procedure in the management system when an event occurrence is notified from the control device.

When receiving event information in the standby state (301), the management system checks the IP of the control device included in the message sent from the control device (302). The management system checks subscriber information through the IP of the control device and checks the content of the event (303). If the event content is gas leak, fire occurrence, illegal intrusion monitoring, and store the video transmitted together in the subscriber's area (304), and transmits a short message to the subscriber's mobile phone previously stored in the database (305).

On the other hand, if the event transmitted from the control device is an environment-related event, the transmitted environment-related data is stored in the area of the subscriber, and it is checked whether the environment data exceeds the reference value (306). If the environmental data exceeds the reference value, a short message is transmitted to the subscriber's mobile phone (307).

6 is a flowchart illustrating a subscriber access in a management system according to the present invention.

The subscriber may access the management system by receiving a short message according to the occurrence of the event or may access the management system at any time if necessary.

When the subscriber station is connected (401), the management system performs subscriber authentication (402). If authentication is successful for the subscriber, the management system provides a menu (403). When the subscriber accesses the management system through the callback URL, a menu corresponding to the URL is provided. However, when the subscriber directly accesses, the upper menu is provided.

The subscriber selects the desired item through the provided menu. The subscriber can access the management system to request remote control of various electrical and electronic devices, to change the mode of the control device, to view stored images, to request real-time monitoring in the home, to make calls, and the like.

After the management system verifies the subscriber's requirements (404), it processes the requirements (405). In the case of the mode change setting, the subscriber may be notified of the processing result (406).

Although the above has been described with reference to the preferred embodiment according to the present invention, those skilled in the art to which the present invention pertains can be carried out by other specific forms of example without changing the technical spirit or essential features of the present invention. I can understand. Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all aspects.
