Description

The present invention relates to a system that can remotely monitor the state of a home or office and issue an alarm using a mobile phone.

In a monitoring alarm system using a network, image information, alarm information, sound information of a monitoring place, and the like to be monitored are analyzed, and when it is determined to be abnormal, the network is used to notify a distant place. When the home or office is absent, the monitoring alarm information is notified to the mobile phone on the go, so that it is possible to promptly respond to an abnormal situation such as issuing an alarm to an intruder.

In such a remote monitoring alarm system, an information collecting function for collecting image information to be monitored, alarm information, etc., an information storing / analyzing function for analyzing collected information and judging whether it is abnormal or not An alarm notification function for notifying a mobile terminal of an abnormality as a result and an instruction relay function for relaying a terminal command to a monitoring target are required. Two methods can be roughly classified according to where these functions are arranged. Method 1 is a method in which all functions are centrally arranged in a communication control device installed in a home or office. Method 2 is a method in which only the information collection function is arranged in the communication control device, and the information storage / analysis function, the alarm notification function, and the command relay function are arranged in the service center server via the network.

FIG. 1 shows a specific configuration of method 2 in which a communication control device 1 and a server 5 are installed. On the other hand, method 1 is a method for providing the communication control device 1 with the function of the server 5, in which case the server 5 is not required, the communication control device 1 directly notifies the mobile phone 6 of an alarm, and if necessary Then, the communication control device is directly accessed from the mobile phone, and stored image information or the like is taken out, or a command is issued to a monitoring target alarm device or the like.

On the other hand, method 2 is a method of sharing various functions between the communication control device 1 and the server 5, and the communication control device 1 shares the collection of monitoring alarm information from the camera / sensors 2, and the server 5 Is a method of sharing monitoring alarm information storage / analysis, alarm notification to the mobile phone 6, and command relay from the mobile phone. This method 2 requires a new function for sending the monitoring alarm information collected by the communication control device 1 to the server 5. Access from the mobile phone 6 to the communication control device 1 is performed via the server 5. The mobile phone 6 accesses the server 5, retrieves image information stored in the server 5, and transmits an instruction to the alarm device or the like to be monitored to the server 5. The server 5 relays the command to the communication control device 1, and the communication control device 1 issues a command to the monitoring target.

The main difference between the method 1 and the method 2 is whether the functions of the communication control device 1 and the server 5 are integrated or separated, but the qualitative and quantitative functions of hardware and software functions required for the communication control device 1 A large difference occurs between the two, and a large-scale remote monitoring and warning system using a large number of communication control devices 1 leads to a large difference in cost.

For example, when constructing a remote monitoring alarm system in which one communication control device 1 is installed in each home or office and a large number of communication control devices 1 are installed as a whole, the communication control device 1 and the server 5 are integrated. In the system 1, the communication control device 1 needs to be equipped with a storage device that records a large amount of information collected from the camera / sensors 2, and must have a processor and a Web function for acting as a server. By implementing these hardware and software functions, it is essential to increase the cost of the communication control device 1. Even if the cost per unit is small, the overall cost will increase significantly.

In the method 2 in which the communication control device 1 and the server 5 are separated, the communication control device 1 immediately transfers the information collected from the cameras / sensors 2 to the server via the network, so that a large amount of information is stored in the communication control device. A storage device for recording can be dispensed with. The server 5 provides a Web function for exchanging information with the mobile phone 6. Therefore, the communication control device 1 can reduce the hardware and software functions as compared with the method 1, and the cost reduction can be significantly reduced as a whole even though the cost reduction is small per unit.

However, even if the method 2 is adopted, a large amount of information acquisition processing that is continuously generated from the camera / sensors 2 that the communication control device 1 is responsible for, the instruction processing to the alarm lamp / alarm device 3, via the network The amount of hardware and software necessary for information transmission / reception processing with servers and related information recording and storage processing is still large (Patent Documents 1 and 2). Many communication control devices 1 are installed in each home or office. When constructing a remote monitoring and alarming system, it is a challenge to reduce the amount of these hardware and software to reduce the total cost.

Further, in the conventional method, in the case of the method 1 for accessing the communication control device 1 from the mobile phone 6 and the method 2 for accessing the communication control device 1 from the server 5, the URL or It is necessary to purchase an IP address from a network operator (Patent Document 3, Non-Patent Document 1), and the Internet usage fee will be added accordingly. Although there is a method called Dynamic DNS as a means of building a similar system without purchasing a URL or IP address from a network operator to avoid this usage fee, Dynamic DNS uses a fixed URL as an address. The IP address allocation corresponding to the URL changes over time, and there is a concern that the reliability of the service provided by the remote monitoring alarm system may be adversely affected by the reliability of the dynamic DNS service.

Furthermore, in remote alarm monitoring systems, it is expected that there will be an increasing demand for simultaneous image collection from multiple cameras in the same home or office, and a method for economically transferring a large amount of image information generated at that time to a server. Development is a challenge.

In addition, when many sensors such as door sensors and vibration sensors are used, there are wired or wireless systems as means for collecting alarm information issued by the sensors. The ratio of the cost increase due to the addition of the information collecting means is large, and there is a problem that increases the cost of the entire system.
JP 2004-072702 JP Japanese Patent Laid-Open No. 2002-034029 JP 2004-326623 A Paragraph 0081 Junichi Mizusawa, “Introduction to Information and Communication Networks” Baifukan, May 27, 2005, P149-154

The invention of claim 1 aims to reduce the hardware and software burden of the communication control device 1 and to provide an inexpensive communication control device 1. The inventions of claims 2, 5 and 6 are provided for each communication control device. The invention of claim 3 is an economical device that accommodates multiple cameras, with the purpose of providing a service that allows the communication control device to be accessed from a mobile phone without purchasing an IP address or URL. An object of the present invention is to provide an economical alarm system using commercially available inexpensive sensors.

The present invention is based on the method 2, and in order to realize the monitoring image / alarm information transfer function between the communication control function 1 and the server 5 required for the method 2, the communication control device 1 in FIG.・ Communication method that immediately sends acquired monitoring images / alarm information to the server 5 via the network for the purpose of minimizing the storage area required for recording and storing large amounts of information that is continuously acquired from the sensors 2 In addition, the communication control device 1 and the server 5 are integrated by integrating communication means that always secures a communication link between the communication control device 1 and the server 5 to solve the above-mentioned problems.

In the remote monitoring alarm system in which a large number of communication control devices 1 of FIG. 1 are introduced for each home or office, the present invention temporarily stores the monitoring alarm information of the communication control device 1 that handles a large amount of monitoring alarm information. As a result, the capacity of the storage device can be reduced to reduce the cost, and a significant economic effect can be achieved as a whole system.

In the conventional method, it is necessary to purchase a URL or IP address for the communication control device 1 from a network operator, and an Internet usage fee is added accordingly. However, in the present invention, the communication control device 1 and the server 5 are added. Since there is always a communication link between and the network, there is no need to purchase a URL or IP address from the network operator, and there is an economic effect that the Internet usage fee can be reduced.

Furthermore, in the conventional method, there is a method called dynamic DNS as a means to construct a similar system without purchasing a URL or IP address from a network operator, but a remote monitoring alarm system is provided by the reliability of the dynamic DNS service. However, according to the present invention, it is not necessary to purchase a URL or IP address from a network operator, and it is not necessary to use dynamic DNS. This has the effect of eliminating the concerns.

In the present invention, in the environment where the Internet 4 shown in FIG. 1 is established as a social infrastructure and the mobile phone 6 capable of displaying a Web page is also widely used, it is intended for homes and offices. When the remote monitoring alarm system is introduced in the camera, the communication control device 1 is installed indoors or outdoors, and the cameras and sensors 2 for collecting the information to be monitored are appropriately installed at the necessary locations. 2 and the communication control device 1 are connected to the communication control device 1 by a wired or wireless line, and the alarm lamp / alarm device 3 that operates by receiving command information from the mobile phone 6 is connected to the communication control device 1 by a wired or wireless line. The communication control device 1 is provided with a stable and always-on communication link with the server 5 via the Internet 4, and the mobile phone 6 also accesses the server 5 at any time to receive a stable Web service. This is the best mode for carrying out the present invention.

An overall system configuration diagram of the remote monitoring alarm system is shown in FIG. 1, and an embodiment of a communication sequence performed between the communication control device 1 and the server 5 according to the present invention is shown in FIG. In the initial stage until the remote monitoring alarm system is started up, it operates as follows. That is, when the communication control device 1 installed in a home or office is turned on 8, it periodically transmits an IP packet 9 a to establish a link to the server 5 via the Internet 4. When the server 4 is not ready, no response is returned from the server 4 to the communication control device 1. However, by periodically retransmitting the IP packet 9 a, the server 5 is ready when the server 5 is ready. Is sent back to the communication control device 1 as a confirmation response IP packet 9b. The communication control device 1 receives the confirmation response IP packet 9b from the server 5 to confirm that a network layer communication link has been established between the communication device 1 and the server 5. The IP packets 9a and 9b serve to function only for network layer link establishment.

In other words, in the IP packets 9a and 9b, when the link in the network layer is established, if the upper protocol indication of the IP header is set to a default protocol such as “6” TCP or “17” UDP, there is a restriction on the protocol of the default protocol. For example, by specifying “63” Any local network, link establishment between the communication control device 1 and the server 5 can be achieved by a unique protocol.

When the communication link of the network layer is established with the server 5 by the above procedure, the communication control device 1 starts acquiring information from the camera / sensors 2. The types of information acquired from the camera / sensor 2 are image information from the Web camera, ambient acoustic information collected by the microphone, ON / OFF signal from the door sensor that detects the opening and closing of the door, and vibration detected when the window glass is opened and closed. This is the ON / OFF signal from the vibration sensor. In a remote monitoring alarm system, there are cases where a large amount of image information, acoustic information, etc. must be obtained and recorded continuously. In such a case, recording information with the communication control device 1 requires a large-capacity storage device for recording, which increases the device cost. In order to avoid information recording with the communication control device 1, The image information 10b acquired from the sensors 2 is immediately transmitted to the server 5 via the Internet. The server 5 records and saves received image information and the like, and performs appropriate image analysis and image processing as necessary, thereby realizing a significant reduction in storage and processing load of the communication control device 1.

Specifically, in a state in which a network layer communication link is established between the communication control device 1 and the server 5, the communication control device 1 can send out a transport layer packet at any time. The transport layer packet is typically a connectionless UDP packet or a connection type TCP packet. However, the transport layer packet is not limited to this, and a similar packet format may be used.

Therefore, the communication control device 1 stores the image information sent from the camera / sensors 2 etc. in a reception buffer (not shown), and transmits the reception buffer immediately after storing the image information etc. for one preset packet. Switching to the buffer starts transmission of image information and the like in the transmission buffer to the server 5 as a UDP packet or a TCP packet.

When transmission of the packet is completed, the transmission buffer is switched to the reception buffer to prepare for storing the next image information and the like. In the case of a UDP packet, the completion of transmission is determined when the packet transmission operation in the transmission buffer is completed. However, in the case of a TCP packet, the transmission is not completed when the packet transmission operation is completed. Transmission is completed when an acknowledgment packet indicating that the TCP packet has been received is received. As described above, in the communication control device of the present invention, the image information and the like are stored in the reception buffer, the reception buffer is switched to the transmission buffer, and the image is temporarily stored only for the time until transmission of the contents of the transmission buffer is completed. Other than storing information or the like in the apparatus, the image information or the like is not stored in the communication control apparatus.

As described above, in the remote monitoring alarm system of the present invention, image information and the like are stored only temporarily in the communication control device 1 but stored and stored in the server 5 for a long time. Therefore, the required capacity of the storage device must be considered not only for the communication control device 1 but also for the server 5 as a whole system.

Therefore, in order to examine it concretely, when calculating the number of facilities in a large-scale remote monitoring and warning system assuming 10,000 users, the communication control device 1 requires 10,000 units, whereas the server About 5 is sufficient for 5 units. When the communication control device 1 is provided with a function for recording information such as camera images, the cost of the entire system increases in proportion to the number of communication control devices 1, whereas a cost item is generated via the network. In the case of recording in the server 5, a large-scale storage device is used for the server 5. However, the storage device has a mechanism that the bit unit price decreases as the scale increases and a storage area is shared by many users. Because it can be applied, it is possible to reduce the equipment investment for storage as a whole remote monitoring and warning system because it is possible to reduce the equipment for information storage.

Here, the effect of a large-scale remote monitoring and warning system with 10,000 subscribers was evaluated, but the effect can be expected from the tens of subscribers below, and if it exceeds 10,000 and tens of thousands to hundreds of thousands Needless to say, the effect is even greater.

Next, the server 5 analyzes the contents of the image information and the like received from the communication control device 1, and provides alarm information 11a to the mobile phone 6 using an e-mail if necessary. For example, when the user desires to receive a door open / close alarm detected by the door sensor with a mobile phone, the mobile phone 6 is notified 11b. Alternatively, if the server 5 performs motion detection software processing on the continuous image information of the Web camera and detects a motion in the image, an e-mail is sent to the mobile phone 6 11a to notify the user of an alarm 11b. To do.

When the user wishes to see the situation at home or office using the mobile phone 6 when receiving the mail, the mobile phone 6 accesses the server 5 for the purpose of examining the Web camera image or the like. . The operation on the mobile phone 6 can be easily accessed by clicking 12a in the URL described in the received mail. When the communication control device 1 is in the continuous transfer operation mode 12b in which the information of the camera / sensors 2 is continuously transferred to the server 5, the server 5 receives the image information of the Web camera being received when accessed from the mobile phone 6. Is immediately transmitted 12c to the mobile phone 6. After confirming the image information and the like with the mobile phone 6, the user can perform an operation such as an alarm command.

When the communication control device 1 maintains the communication link with the server 5 and is not in an operation mode in which Web camera information is continuously sent to the server 5, the server 5 performs communication control in response to a request from the mobile phone 6. An instruction is issued to the apparatus 1, and image information and the like are acquired from the cameras and sensors via the Internet 4 and transmitted to the mobile phone 6.

It will be described in detail how the instructions and commands given by the user to the server 5 from the mobile phone 6 are relayed and correctly sent to the communication control device 1 of the user.
First, the server 5 stores the table information shown in Table 1 in a storage device. The device number of the communication control device in Table 1 is a device number unique to each device called a MAC address assigned to the communication control device installed in the user's home or office, and the subscriber name is a contract. The mobile phone device number is the MAC address assigned to the mobile phone number, and the subscriber can register the device number for multiple mobile phones and is communicating. The IP address is an IP address indicating the communication control device 1 among the IP addresses currently used in the link established by the communication control device 1 and the server 5.

When the mobile phone 6 receives an e-mail and clicks 12a on the URL described in the received e-mail, a wireless IP packet is transmitted from the mobile phone 6 and received by a mobile phone base station (not shown). The URL is analyzed by a server (not shown) in the mobile IP network, and the wireless IP packet is transferred to the Internet 4 and received by the server 5.

The wireless IP packet received by the server 5 describes an IP address of a server (not shown) in the mobile IP network 7 and a MAC address that is a unique device number of the mobile phone. Therefore, the server 5 refers to Table 1 and reads out the subscriber name and the IP address during communication corresponding to the unique device number of the mobile phone. After that, when an instruction / instruction issued by the user according to the screen display of the mobile phone is sent to the server 5, the server 5 is in communication with the communication control device 1, and therefore the communication link is established. By assembling a packet as one of the communication messages with the IP address in communication as the destination, and describing the command / instruction to be relayed in the packet, the command / instruction is correctly transmitted to the communication control device 1 of the user. Will be sent. It is also possible to read out the image corresponding to the subscriber name from the image file being stored and send it to the mobile phone, or to send the image information during communication corresponding to the IP address during communication as it is to the mobile phone.

Since the user may wish to use a plurality of mobile phones, the device numbers of a plurality of mobile phones can be registered in the table shown in Table 1. The same IP address during communication can be read from the table even if the server is accessed from any of the mobile phones, and which mobile phone is used among a plurality of mobile phones registered by the user. However, the command / instruction intended by the user is transmitted to the intended sensors or alarms.

In addition, it is considered that the method of determining the subscriber name based on the MAC address of the telephone and reading out the IP address during communication is not preferable because the mobile phone is stolen or a command / instruction by a malicious third party is transmitted. As a countermeasure against this, there is a method in which a user ID and password, which are widely used, are notified from the subscriber in advance and used.

In this method, the server has a table shown in Table 2. In Table 2, the device number, subscriber name, and communicating IP address of the communication control device are the same as in Table 1. The user ID and password are reported in advance by the contract subscriber, and replace the device number of the mobile phone. In this case as well, a plurality of user IDs and passwords can be registered.

When the mobile phone 6 receives an e-mail and clicks 12a on the URL described in the received e-mail, a wireless IP packet is transmitted from the mobile phone 6 and received by a mobile phone base station (not shown). Table 1 shows that the URL is analyzed by a server (not shown) in the mobile IP network, the wireless IP packet is forwarded to the Internet 4 and received by the server 5. It is the same as the case of.

In the wireless packet received by the server 5, the IP address of the server (not shown) and the MAC address of the mobile phone in the mobile IP network are described, but the user ID and password are not described. 5 sends a packet prompting the user to input a user ID and password to a server (not shown) in the mobile IP. At this time, since the MAC address of the portable terminal is also sent from the server 5 to a server (not shown), the server (not shown) sends a user ID and password input promotion packet to the portable terminal having the MAC address. As a result, a screen prompting the user ID and password is displayed on the display screen 6f of the mobile phone.

In response to this, when the user inputs the user ID and password using the operation buttons of the mobile phone, the information is converted into a wireless packet and transferred to the server 5. The server 5 that has obtained the user ID and password refers to Table 2, searches using the user ID as a key, confirms that the corresponding password is correct, and reads the corresponding subscriber name and IP address during communication. . After that, when a command / instruction issued by the user according to the screen display of the mobile phone is sent to the server 5, a packet is assembled as one of the messages being communicated with the IP address during communication as the destination, and the command / instruction is transmitted. The point that the command / instruction is sent to the communication control device 1 of the user by relaying is the same as the case of using the MAC address. Similarly, the image corresponding to the subscriber name is read from the image file being saved and recorded and sent to the mobile phone, or the image information being communicated corresponding to the IP address being communicated is directly sent to the mobile phone.

FIG. 3 shows an example of a display screen 6f of a mobile phone. The image information and the like sent from the communication control device 1 to the server 5 has a large amount of information, so it is difficult to display all on the display screen 6f of the mobile phone 6 at a time. In FIG. 3, the communication control device 1 transmits information from three Web cameras to the server, and transmits three Web camera information 6 a, 6 b, 6 c from the server to the mobile phone 6, which is displayed on the display of the mobile phone 6. It is an example displayed above. The display screen of the mobile phone 6 displays the operating status of the camera / sensors 2 and alarm lamp / alarm sound device 3 in addition to the image captured by the Web camera 6d, and the alarm lamp / alarm sound device ON / OFF Buttons 6e for issuing commands are also displayed.

When there is a large amount of information and it is difficult to display all the information at once, there is a method of switching the display page, etc., but in FIG. Shows an example of displaying a part 6g and browsing the necessary part by scrolling the screen.

A user who wants to issue an alarm to an intruder at home or office by looking at the Web camera image displayed on the mobile phone, uses the screen that the server 5 sends to the mobile phone 6 to issue the alarm. Can be sent. As shown in the lower part of FIG. 2, when the alarm lamp ON13a is instructed by the mobile phone 6, the information is transmitted to the server, the server 5 transmits the alarm lamp ON instruction 13b to the communication control device 1, and the communication control device 1・ Turn 13d on the alarm lamp mounted on alarm sound device 3

When the number of Web cameras accommodated in the communication control device 1 is plural, a large amount of image information is collected, and at the same time, it is necessary to devise a method for recording the information. By adopting the storage and transmission method of image information and the like in the above-described communication control device 1 of the present invention, the communication control device 1 can transfer such a large amount of information to the server 5 without having a function of recording and storing such information. Is possible.

FIG. 4 shows an example of a communication sequence when three Web cameras are connected as the cameras / sensors 2 of one communication control apparatus 1. Web camera 1, Web camera 2, and Web camera 3 simultaneously capture images and send them to communication control device 1 14 a, 14 b, and 14 c.

First, the communication control device 1 starts storing the image information from the Web cameras 1, 2, 3 in the corresponding reception buffers 1, 2, 3 (not shown). Switch to 2 and 3, and connect to a transmission queue (not shown) for the server 5 and simultaneously store the subsequent image information using the new reception buffers 4, 5 and 6 that have been secured. Next, the communication control device 1 starts transmission of the contents of the transmission buffer 1 to the server 5, and immediately starts transmission of the contents of the transmission buffer 2 to the server 5 without waiting for completion of transmission when the transmission operation ends, and transmits when the transmission operation ends. By immediately starting transmission of the contents of the transmission buffer 3 to the server 5 without waiting for completion, the image information of any Web camera is not stored in the communication control device 1 over a long period of time, and a large-capacity storage device is provided. A communication control device that accommodates multiple Web cameras without having them can be realized.

As the importance of ensuring safety in social life increases, various alarm devices are commercially available at low cost. However, if such an inexpensive alarm device is incorporated in the remote monitoring alarm system, a wired or wireless circuit must be added between the communication control device 1 as information collecting means from the inexpensive alarm device. Since the alarm device itself is inexpensive, the cost of the additional circuit is relatively large, raising the overall cost of the remote monitoring alarm system. Therefore, we will try to solve the problem by constructing a remote monitoring alarm system using acoustic information emitted by low-cost alarm devices without using wired or wireless lines.

In FIG. 5, a commercially available alarm device 16 is linked to a remote monitoring alarm system, and an alarm sound emitted by the commercially available alarm device 16 is picked up by a microphone 2d connected to the communication control device 1, so that an inexpensive commercial product is used as a sensor. In addition, a wired / wireless line that is normally required between the sensor and the communication control device 1 is not required, and further, construction costs associated with installing the sensor can be saved.

In the communication sequence of FIG. 5, as a commercially available alarm device 16, an alarm sound 15a generated by a door sensor, a vibration sensor, etc. is picked up by a communication control device 1 with a microphone 2d, 15b, transmitted to a server 5, 15c, and collected by the server 5. It is determined that the alarm sound is an alarm for notifying an abnormal situation 15e, and a communication sequence of 15f case of alarm notification to a mobile phone is shown.
