Description

  The present invention relates to a crime prevention system, and more specifically, a communication device is provided that can suppress a communication amount for notifying a failure even when a failure occurs in a system component device. Is.

  Currently, security systems using security cameras and the like are becoming popular in ordinary homes. Such a security system generally includes a security device such as a device that detects the state of an intruder with a camera or a sensor, a storage device that stores a captured video of the intruder, a video stored in the storage device, It comprises a communication device that transmits intrusion information to a security company or owner. And when a suspicious person's intrusion is detected by a sensor, the video taken by the camera is extracted from a few seconds before the detected time and sent to a security company or the owner's computer via a communication device. I have to.

  By the way, in such a crime prevention system, it is designed to detect that a camera, sensor, storage device or the like has failed, and when the operation status of the device is regularly monitored and an abnormality of the device is detected. This is output to a communication device, and failure information is transmitted via the communication device (Patent Document 1).

JP 2002-44750 A

  However, when failure information is transmitted using such a crime prevention system, there are the following problems.

  That is, for example, when a failure occurs in the hard disk, information indicating that the failure is always “failure” is output from the failure detection unit, and therefore the same failure information is transmitted many times from the communication device. However, unlike intrusion detection information, such information is not as urgent as to compete for a moment, so if a large amount of the same data is transmitted in a short time, the receiving side will It is necessary to determine which data is highly urgent information, and the work takes time. In addition, when sending such data, mail will be sent via the Internet via a provider, but if a large amount of data is sent, if you have a dial-up contract, the communication cost will be Can be enormous. For this reason, in general, there has been a problem that it is necessary to make a high-priced contract with a fixed communication fee such as ADSL or optical service.

  Accordingly, the present invention has been made paying attention to the above-described problem, and can provide a crime prevention system that can transmit only necessary data while reducing the amount of communication even when a failure occurs in a device. It is intended to do.

That is, in order to solve the above problems, the present invention provides an intrusion information acquisition unit that acquires intrusion information of a suspicious person, a component device such as a storage device that stores video, and a failure detection unit that detects a failure of the component device. And when the intrusion information of the suspicious person has been output from the security device, the intrusion information is transmitted to the first transmission destination and from the security device. When failure information is output, the identification code and error code of the component device are stored in the storage unit, and at the preset timing, the number of times the failure is detected for each identification code and error code, the first failure And the last time when the failure was detected are extracted and transmitted to the second transmission destination .

In such an invention, when the failure information is output, the identification code and error code of the component device are compared with the information stored in the storage unit, and the identification code within a predetermined time range is obtained. Is not stored , or only the time of occurrence is additionally stored.

According to the present invention, when the intrusion information of the suspicious person has been output from the security device, the intrusion information is transmitted to the first transmission destination, and when the failure information has been output from the security device, the configuration The device identification code and error code are stored in the storage unit, and at the preset timing, for each identification code and error code, the number of times the failure was detected, the time when the failure was first detected, and finally the failure was detected. Since the time is extracted and sent to the second destination , intrusion information with high urgency is sent to the security company computer or owner computer that is the first destination, and the urgency Failure information that is not too high can be sent to the second destination computer, such as a maintenance company computer. Each time over data is transmitted, there is a merit that its importance is not necessary to select. In addition, when transmitting failure information, it is possible to reduce the cost by reducing the amount of communication.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the security system 1 in this embodiment includes a security device 2 that detects an intruder, and information detected by the management company side computer 51, owner side computer 53, and security company side computer 52. The communication device 3 is configured to transmit to the maintenance company side computer 54 and the like. Among these, the crime prevention device 2 includes an intrusion information acquisition unit 21 for acquiring intruder information as shown in FIG. A storage device 22 for storing the acquired information, a failure detection unit 23 for detecting a failure of a component device including the intrusion information acquisition unit 21 and the storage device 22, and the like. A transmission information creation unit 24 for creating a mail for notification, and a first communication unit 25 that outputs information created by the transmission information creation unit 24 to the communication device 3 Configured with the etc.. Characteristically, as the communication device 3 provided in association with the security device 2, the second communication unit 31 receives the security information and failure information output from the first communication unit 25 of the security device 2. When the determination unit 32 determines the type and determines that the information is security information, the information is transmitted to the security company computer 52, the owner computer 53, etc. as the first transmission destination. When the determination unit 32 determines that the failure information has been output, the failure information is temporarily stored in the storage unit 33 and transmitted to the maintenance company computer 54 as a second transmission destination. The communication unit 34 is configured. With this configuration, intrusion information with high urgency is quickly communicated, and failure information that is not very urgent is collectively notified to the management company or maintenance company at a certain timing. It is a thing. Hereinafter, the configuration of the present embodiment will be described in detail. 2 is realized by cooperating a storage device such as a CPU, a ROM, and a RAM constituting a computer, and a program stored in the storage device.

  First, the intrusion information acquisition unit 21 of the security device 2 includes a camera that acquires an intruder's image and video, a detection sensor such as infrared rays, and the like. These intrusion information acquisition units 21 are connected to the main body of the security device 2 in a wired or wireless manner, always acquire images and videos with a camera, and when an intruder is detected by a detection sensor such as an infrared ray, When any movement is detected on the video, the video is acquired and stored in the storage device 22.

  The storage device 22 is configured by a storage device such as a hard disk. In addition to the video acquired by the intrusion information acquisition unit 21, a program for operating the constituent devices and a first transmission for informing the intrusion information Information such as the second transmission destination for notifying the destination and failure information is stored. In addition, when storing the image | video for crime prevention in this memory | storage device 22, it is generally memorize | stored in the hard disk incorporated in the main body, but besides this, the large-capacity storage medium which can be taken out, or an external hard disk Or the like. In addition, when storing video in this way, the capacity increases depending on the image quality.For example, only when a motion is detected on the video, a video of several seconds before and after the detected time is stored. In addition, other videos may be deleted in order from the oldest one.

  The failure detection unit 23 is configured by a program stored in the storage device 22 and checks the operation state of the storage device 22 such as a camera, a detection sensor, and a hard disk at a predetermined timing. Detect whether or not there is. In such a failure detection unit 23, for example, a failure is detected when writing or reading of the hard disk becomes unstable. The timing for detecting this failure may be every time set in advance on the crime prevention apparatus 2 side, or the timing for spontaneous transmission from each component device, the timing for detecting the intrusion, the management company, etc. The timing at which the diagnostic command is transmitted from the communication device 3 through the communication device 3 may be used. However, if a management company or the like monitors the life and death state of the security device, communication costs are incurred. Therefore, preferably, a diagnostic command is transmitted from the communication device 3 to the security device 2 and there is no response. In this case, it is preferable that failure information can be transmitted to a management company.

  When such a failure is detected or an intrusion is detected, the transmission information creation unit 24 creates a mail for outputting information to that effect via the communication device 3. Specifically, when intrusion of a suspicious person is detected, the transmission information creation unit 24 extracts a video from a few seconds before the time from the storage device 22 and stores the first information stored in the storage device 22. Is acquired, and an e-mail is created so that the video file can be transmitted as an attached file to the first destination. On the other hand, when a failure is detected, in addition to the “information indicating failure”, an email including the identification code of the component device that has failed, the error code of the failure type, and the failure diagnosis time is created. At this time, for example, if a hard disk write error is detected, “information indicating failure information, hard disk identification code, write error code, time of occurrence ○ year ○ month ○ date ○ hour ○ minute”, etc. Create an email that contains the information and send it to the second destination.

  The first communication unit 25 outputs the mail information created by the transmission information creation unit 24 toward the second communication unit 31 of the communication device 3. This output can be output by wired or wireless LAN. The first communication unit 25 not only outputs information toward the second communication unit 31, but also accepts input of information from the communication device 3 as shown in FIG. Yes. As such reception of the input, for example, a failure diagnosis command from the communication device 3 side, information for time correction in the security device 2 and the like can be considered. For such time correction, the time disclosed on the Internet or the time acquired by using a mobile network or the like is used, and this is periodically output to the security device 2 to correct the system time. .

  In such a configuration, the communication device 3 which is a feature of the present invention is configured as follows.

  First, the second communication unit 31 transmits and receives information to and from the first communication unit 25 of the security device 2. Here, each information is set to be transmitted and received by wired or wireless LAN.

  Further, the determination unit 32 determines the type of information transmitted from the security device 2. Examples of the information type include intrusion information and failure information, and the failure information includes information such as a camera failure, a detection sensor failure, a hard disk failure, and a power failure. When the determination unit 32 determines that the intrusion information has been output as mail information, the information directly passes through the third communication unit 34, for example, the information flow of “a” in FIG. As shown in FIG. 4, the information is transmitted to the security company computer 52, the owner computer 53, or the management company computer 51 by e-mail.

  On the other hand, when failure information is output from the security device 2, it is memorize | stored in the memory | storage part 33 for every classification of the failure information. Since these pieces of information are transmitted from the security device 2 at each failure detection timing, for example, the same information is transmitted about once every few minutes, but the same information is stored in the storage unit 33 each time. Accumulate failure information. At this time, if an identification code of a different component device is output, as shown in FIG. 4, “information indicating failure information, component device identification code, write error” is newly added for each identification code. Information such as code, time of occurrence ○ year ○ month ○ day ○ hour ○ minute "is accumulated. Then, at a predetermined timing, these pieces of information are transmitted by e-mail to the second transmission destination via the third communication unit 34. At this time, if the failure information accumulated in large quantities is transmitted as it is, the amount of communication increases.For example, for each identification code and error code of the component device, the number of times the failure was detected, the time when the failure was first detected Finally, information such as the time when the failure was detected is extracted, and the information can be sent by e-mail. Here, when failure information is transmitted from the crime prevention device 2, the information is sequentially accumulated. For example, when failure information is transmitted, identification of the component device is performed. The code and the error code are compared with the information stored in the storage unit 33, and if the identification code and the error code are within the predetermined time range, the information is not stored or only the occurrence time is determined. Additional storage may be performed. In this way, even when the capacity of the storage unit 33 is small, various pieces of failure information can be accumulated, and the storage capacity is not filled up.

  Next, an operation flow in the crime prevention system 1 configured as described above will be described with reference to flowcharts shown in FIGS. 5 and 6. As a premise, it is assumed that the video is always acquired by the camera and the time corrected by the security device 2 is also stored.

  First, when the security device 2 detects the intrusion of a suspicious person (step S1), the video of several seconds before and after the detected time is read from the storage unit 33 (step S3), and an e-mail is created with the video as an attached file. (Step S4). When creating this e-mail, the e-mail address, which is the first destination information, is acquired based on the intrusion detection information, and the e-mail including the time and video is created. And the information which shows that it is intrusion information with this mail information is added, and it outputs to the 2nd communication part 31 of the communication apparatus 3 from the 1st communication part 25 (step S5).

  Then, in the communication device 3 (step T1 in FIG. 6) that has received this, when it is determined that the information output from the crime prevention device 2 includes information indicating intrusion information (step T2, T3) A communication state with the Internet is established, and the mail information is transmitted as it is to the first transmission destination (step T6).

  On the other hand, when the security device 2 side detects a failure of the system component device (step S2), the security device 2 always outputs information indicating “failure” while detecting the failure. In each case, the transmission information creation unit 24 of the security device 2 extracts the mail address of the second transmission destination from the storage unit 33 as the transmission destination, and “configuration indicating failure information, failure detected configuration” An email including information such as the device identification code, error code, time of occurrence (year, month, day, hour, minute) is created (step S4). And this mail information is output to the 2nd communication part 31 of the communication apparatus 3 via the 1st communication part 25 (step S5).

  Then, as the communication device 3 (step T1 in FIG. 6) that has received this information, the determination unit 32 determines that “information indicating a failure is included” (steps T2 and T3), and the information is temporarily stored in the storage unit. 33 (step T4). At this time, the failure information is stored for each failure type of the component device as shown in FIG. Then, as the preset timing, for example, the failure information stored in the storage unit 33 is read every predetermined time every day, and the information is sent to the maintenance company computer 54 or the like via the third communication unit 34. I will send it.

As described above, according to the present embodiment, component devices such as the intrusion information acquisition unit 21 that acquires intrusion information of a suspicious person and the storage device 22 that stores video, and failure detection that detects a failure of the component device. When the intrusion information of the suspicious person is output from the crime prevention device 2 in the communication device 3 connected to the crime prevention device 2 including the unit 23, the intrusion information is transmitted to the first transmission destination, When failure information is output from the security device 2, the identification code and error code of the component device are stored in the storage unit 33, and the failure is detected for each of the identification code and error code at a preset timing. number, first time of detecting a failure, since so as to transmit the second destination to extract the last time that has detected the failure, at a certain timing is not required failure information urgency It is possible to reduce the traffic by sending the like Mamoru company computer 54. As a result, it is possible to contract with a provider with a relatively cheap contract such as a dial-up contract, and the maintenance cost of the system can be reduced. In addition, for the existing crime prevention device 2, the communication amount can be reduced and the cost can be reduced without using the crime prevention device 2 itself by simply using the communication device 3.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, in the above embodiment, the crime prevention device 2 and the communication device 3 are connected via a LAN. However, the crime prevention device 2 and the communication device 3 may be connected using a cable that notifies intrusion information or failure information using an alarm signal. In this case, when a failure occurs in a component device, an alarm signal is always output to the communication device 3 side. However, the communication device 3 side also temporarily pools information on the alarm that is always output. In addition, by collectively transmitting at a fixed timing, it becomes possible to reduce the amount of communication at the time of failure.

  Moreover, in the said embodiment, information, such as a 1st transmission destination and a 2nd transmission destination, is memorize | stored in the crime prevention apparatus 2 side, and the transmission information preparation part 24 accompanying this is also in the crime prevention apparatus 2 side. However, such information may be provided on the communication device 3 side.

  Further, in the above embodiment, the management company side computer 51, the security company side computer 52 and the owner side computer 53 are used as the first transmission destination, and the management company side computer 51 and the maintenance company side computer 54 are used as the second transmission destination. However, these transmission destinations are not limited to this.
