Description

Door phone system, wireless device, and monitoring method

The present invention relates to a door phone system, a wireless device used in the door phone system, and a monitoring method using the door phone system.

In the past, in order to monitor the situation from the inside of the room to the outside, such as monitoring the intrusion of a suspicious person into the site from the inside, it has been conventionally performed. However, it is troublesome and expensive to install a communication cable between the outdoor monitoring camera and the indoor device that presents the camera video. On the other hand, since the outer wall of the building has a high radio wave shielding property, it is difficult to connect the surveillance camera and the indoor device by wireless communication.

Therefore, it has been proposed to add an outdoor monitoring function to a door phone system having an entrance slave unit installed at the entrance and a door phone master unit installed indoors (see, for example, Patent Document 1).

The entrance cordless handset is usually installed outside the exterior wall of the entrance. The technique described in Patent Document 1 (hereinafter referred to as “prior art”) arranges a surveillance camera with a human sensor outdoors, and receives information transmitted from the surveillance camera by wireless communication to the entrance unit. A wireless communication unit is provided. The entrance slave unit transmits the information received from the monitoring camera to the door phone master unit by wired communication, in the same manner as the information acquired by the normal door phone function. When receiving information indicating that a person has been detected, the door phone master unit outputs a predetermined alarm.

Such a conventional technique makes it possible to more easily introduce a system for monitoring the presence or absence of a suspicious person outdoors from the room.

However, in the prior art, for example, when a public parking lot near a gate near a road or other vehicles is monitored, a person who is not a suspicious person is detected and an alarm is output unnecessarily. There is a fear. For this reason, conventional surveillance cameras cannot be arranged in such places. Therefore, the prior art has a problem that the range that can be monitored is very limited.

An object of the present invention is to provide a door phone system, a wireless device, and a monitoring method capable of monitoring a wider range.

FIG. 3 is a diagram illustrating an example of the target information table.

As shown in FIG. 3, the target information table 610 describes a name 612, an image 613, an alarm condition 614, and a threatening action 615 in association with the identification information 611 of the wireless device 300.

Name 612 is a name representing the monitoring target. The image 613 is an image showing the appearance of the monitoring target, for example, an image obtained by photographing the monitoring target. That is, the name 612 and the image 613 are monitoring target information. The alarm condition 614 is a condition for outputting an alarm for alerting the user. Here, the alarm is, for example, a predetermined beep sound and display of a name 612 and an image 613. The monitoring target information is, for example, a display of the number of times motion detection information has been received in a predetermined period such as that day. The threatening action 615 is whether or not to perform a threatening action and the contents of the threatening action.

Note that the alarm condition 614 may be a condition including the type of movement, such as whether it is vibration or rotation, or a condition including the intensity of movement, such as an acceleration value. In this case, each wireless device 300 needs to include information necessary for determining whether or not each alarm condition 614 is satisfied on the side of the doorphone parent device 500 in the motion detection information. For example, the motion detection information may include tilt detection information indicating that the tilt is equal to or greater than a predetermined angle.

In addition, when the target processing unit 530 described later instructs the wireless device 300 to execute a threatening operation on the condition that the user presses a threatening button (not shown) provided in the doorphone master device 500, a threatening operation is performed.

The method of including is mentioned. In the former case, the information relay unit 430 of the front door device 400 needs to transmit threatening instruction information only to the instructed wireless device 300. In the latter case, the device communication unit 320 or the threatening operation unit 350 of the wireless device 300 determines whether or not the identification information included in the threatening instruction information matches the identification information stored in the identification information storage unit 310. It is necessary to determine whether to execute the process.

Note that the target-specific processing unit 530 may transmit the threatening instruction information on the condition that a threatening button (not shown) provided in the doorphone parent device 500 is pressed, as described above.

The device on / off control unit 540 controls on / off of an operation related to execution of the processing for each of at least one of the wireless device 300, the entrance slave device 400, and the door phone master device 500.

More specifically, the device on / off control unit 540 generates an on / off signal at a predetermined timing, and transmits the on / off signal to the entrance slave device 400 via the parent device communication unit 520. Here, the on / off signal is a signal for designating the wireless device 300 and instructing on / off of the monitoring operation (motion detection) of the wireless device 300. In addition, the predetermined timing (hereinafter referred to as “on / off timing”) refers to the on / off time scheduled via the user interface for each wireless device 300 (each monitoring target), or the wireless device via the above-described user interface. This is the timing when an on operation or an off operation is performed with 300 (monitoring target) specified.

When the motion detection information is received (S2100: YES), the target processing unit 530 advances the process to step S2200. Moreover, the process part 530 according to object advances a process to below-mentioned step S2500, when motion detection information is not received (S2100: NO).

In step S2200, the target processing unit 530 extracts identification information from the motion detection information.

In step S2300, the target processing unit 530 presents the monitoring target information corresponding to the extracted identification information to the user according to the target information table 610 (see FIG. 3). For example, when the motion detection information including the identification information “2” is received three times per minute, the target processing unit 530 outputs a beep sound from the doorphone parent device 500 and the name of the monitoring target “car”. And a car image.

If the alarm condition 614 of the target information table 610 includes a condition based on the reception history of the motion detection information, the target-specific processing unit 530 needs to record the timing at which the motion detection information is received for each identification information. is there.

In step S2400, the target processing unit 530 generates threat instruction information that instructs the wireless device 300 indicated by the extracted identification information to execute a threat action according to the target information table 610 (see FIG. 3). . Then, the target processing unit 530 transmits the generated threat instruction information to the entrance slave device 400 via the parent device communication unit 520.

For example, when the motion detection information including the identification information “2” is received three times per minute, the target processing unit 530 generates intimidation instruction information including content for instructing the beep sound to sound for 10 seconds. .

In step S2500, device on / off control section 540 determines whether the on / off timing of any wireless device 300 has arrived. As described above, this timing is, for example, the timing when the user performs an on / off operation.

The device on / off control unit 540 advances the process to step S2600 when the on / off timing has arrived (S2500: YES). In addition, when the on / off timing has not arrived (S2500: NO), apparatus on / off control unit 540 advances the process to step S2700 described later.

In step S2600, device on / off control unit 540 generates an on / off signal designating wireless device 300 and instructing on / off of the monitoring operation, and transmits the signal to entrance child device 400 via base unit communication unit 520. .

In step S2700, the target processing unit 530 determines whether or not an instruction to end the monitoring using the wireless device 300 is made by a user operation or the like.

If there is no instruction to end the monitoring (S2700: NO), the target processing unit 530 returns the process to step S2100. Note that the target processing unit 530 desirably performs the determination process in step S2100 at a predetermined time interval such as a communication interval with the entrance slave device 400 described later. Further, the target processing unit 530 ends the series of processes when there is an instruction to end the monitoring (S2700: YES).

By such an operation, the intercom base unit 500 performs target-specific processing such as displaying a corresponding monitoring target image or sounding a beep sound in the corresponding wireless device 300 every time motion detection information is received. It can be carried out. Further, door phone base unit 500 can control on / off of the monitoring operation for each wireless device 300.

<Operation of the entire system>
Next, the overall operation of the door phone system 100 when each device performs the above-described operation will be described.

FIG. 6 is a sequence diagram illustrating an example of an operation related to motion detection of the door phone system 100.

The front door device 400 transfers this motion detection information to the doorphone parent device 500 (S3040). In response to the transfer, the doorphone parent device 500 performs target-specific processing such as display of an image of a monitoring target whose motion has been detected and alarm sounding (S3050).

The user receives the alarm sound and approaches the doorphone base unit 500, and confirms in which monitoring target the motion is detected from the displayed monitoring target image. If the user determines that threatening is necessary as a result of the confirmation, the user presses the threatening button of the doorphone master unit 500 (S3060). The threatening button may be provided on the information terminal described above.

Then, door phone base unit 500 detects the pressing of the threatening button (S3070), and transmits the threatening instruction information to front door slave 400 (S3080). The front door device 400 transfers the threatening instruction information to the wireless device 300 (S3090). In response to the transfer, the wireless device 300 performs a threatening operation such as outputting a beep sound (S3100), and threatens and repels the suspicious person (S3110).

As described above, when the suspicious person applies a force to the monitoring target, the door phone system 100 can detect this by motion detection and perform processing according to the monitoring target.

FIG. 7 is a sequence diagram illustrating an example of an operation related to on / off of the monitoring operation of the door phone system 100.

When the user designates one of the wireless devices 300 (monitoring target) and performs an operation for instructing to turn on the monitoring operation (S4010), the doorphone parent device 500 detects this operation (S4020), and the wireless device 300 is operated. Is transmitted to the front door 400 (S4030). The front door device 400 transfers this ON signal to the wireless device 300 (S4040). In response to the transfer, the wireless device 300 starts motion detection (S4050).

When the user designates one of the wireless devices 300 (monitoring target) and performs an operation of instructing to turn off the monitoring operation (S4060), the doorphone parent device 500 detects this operation (S4070), and performs the above wireless communication. An off signal designating the device 300 is transmitted to the front door 400 (S4080). The front door device 400 transfers this off signal to the wireless device 300 (S4090). In response to the transfer, the wireless device 300 ends the motion detection (S4100).

Thus, the door phone system 100 can switch monitoring on and off from the room for each wireless device 300.

<Transmission / reception timing of wireless communication>
