Waiting signal reception waiting process (S310) and, when the scream detector 200 receives a visitor call signal from the household entrance camera 300, whether or not the door is opened during the preset door open detection waiting time from the time of receiving the visitor call signal When the door open detection waiting process (S320) to detect and the door open signal from the home door magnetic detector 400 is received within the door open detection waiting time by the scream detector 200, the scream is screamed during the preset scream detection waiting time. It may include a scream detection waiting process (S330) of detecting whether or not occurrence, and an emergency alarm generation process (S334) of generating an emergency alarm when the scream is detected within the scream detection waiting time by the scream detector 200 (S334). It will be described in detail below.

The signal reception waiting process (S310) is a process in which the scream detector 200 waits for reception of a visitor call signal from the household entrance camera 300 and a door open signal from the household entrance magnetic detector 400.

Waiting for such signal reception may be performed in four ways as follows.

The first method is a method of waiting for reception of a visitor call signal and a door open signal from the household video phone 100 as shown in FIG. 4. It waits for reception of a visitor call signal and door open signal through RS-485 or a contact point from the household video phone 100.

The second method is a method of waiting for reception of a visitor call signal and a door open signal via a gateway, as shown in FIG. 5. The visitor call signal and the door open signal are primarily transmitted to the household video phone 100, and the visitor call signal and the door open signal relayed from the household video phone 100 pass through the gateway through the Ethernet communication to the scream detector 200. Is provided as.

The third method is a method of waiting for reception of a visitor call signal and a door open signal from a household wall pad, as shown in FIG. 6. Through the generation wall pad, it can be received through RS485 or Ethernet communication.

The fourth method, as shown in FIG. 7, is a method of waiting for a direct reception of a visitor call signal from the household door camera 300 and a direct reception of a door open signal from the household door magnetic detector 400. The signals directly received in this way are relayed and transmitted to the generation video phone 100.

In the door open detection waiting process (S320), when the scream detector 200 receives a visitor call signal from the household entrance camera 300, a preset door open detection waiting time (e.g., 3 minutes) from the time of receiving the visitor call signal It is the process of detecting whether the door is open for ~5 minutes). For example, when the waiting time for door open detection is set to 3 minutes, whether or not the door is opened is monitored and detected until 3 minutes elapse from the time when a visitor call signal is received.

In the scream detection waiting process (S330), when the door open signal is received from the home door magnetic detector 400 within the door open detection waiting time, the scream detector 200 detects a preset scream from the time when the door open signal is received. It detects whether or not scream has occurred during the waiting time (10~60 seconds). For example, when the scream detection waiting time is set to 10 seconds, whether or not screaming occurs for 10 seconds from the time when the door open signal is received is detected. For reference, in the scream detection waiting process (S330), even if there is no visitor call signal, the scream detection wait is performed, but even if the scream is recognized, the alarm call is not made.

The emergency alarm generation process (S340) is a process of generating an emergency alarm when a scream is detected within the scream detection waiting time. An emergency alarm signal may be transmitted to the household video phone 100 to generate an emergency alarm sound from the household video phone 100. In addition, an emergency alarm signal can be transmitted to a separate alarm so that an emergency alarm sound can be generated from the alarm. Therefore, it is possible to request help by notifying neighboring households that there is an intruder through an emergency alarm sound.

Furthermore, in the emergency alarm generation process (S340), in the emergency alarm generation process (S340), when a scream is detected within the scream detection waiting time, an emergency rescue message (emergency rescue SMS, emergency rescue MMS) is sent to a previously registered mobile phone. Can be sent. That is, a rescue request can be made by sending a text message to the current location of the house and an emergency rescue request through the mobile phone of a friend, family member, or relative registered in advance.

On the other hand, the present invention may be provided with a switch capable of stopping the function of detecting a scream, which is an abnormal sound source, when necessary. That is, as shown in FIG. 8, when the scream detector 200 is installed on the interior wall of the entrance of the household, the scream detector 200 may have a scream detection on/off switch capable of turning on/off the scream detection function. have. When the scream detection on/off switch is turned on, the scream detection function is activated and the detection function is activated for a specified time (10 to 300 seconds). On the other hand, when the scream detection on/off switch is turned off, the scream detection function is stopped. A switch that turns “ON” when a visitor does not call the house entrance camera and calls by knocking or yelling at the door, and “OFF” when there is a risk of malfunction of the scream detector due to a large internal noise such as a dog barking when visiting a visitor. to be.

Therefore, in the scream detection waiting process (S330), when turned on by operating the scream detection on/off switch, even if there is no visitor call signal from the household entrance camera 300, an alarm call is made when a scream is detected within a specified time, and scream detection on/off If the off switch is turned off, the alarm will not be called even if a scream is detected for the specified time.

Meanwhile, information such as a visitor call signal and a door open signal received are stored in a storage and can be used later. In particular, a visitor call signal including a visitor image during screaming may be stored in an internal storage device other than the household video phone 100, so that it can be used as evidence later.

However, the internal storage provided inside the scream detector 200 is a flash memory, a compact flash card, an SD card (Secure Digital Card), a SM card (Smart Media Card), and an MMC card. -Media Card), memory stick (Memory Stick), etc., because it is implemented as a memory card with a small storage capacity, it is necessary to efficiently store the sensing information during the scream detection waiting time. That is, it is necessary to implement so that only necessary information at an important moment, such as when a scream is detected, is stored and the rest is not stored.

To this end, when scream is not detected during the scream detection waiting time, only essential information is stored. That is, when the scream is not detected during the scream detection waiting time, only the visitor image in the visitor call signal collected during the door open detection waiting time is stored in the internal storage of the scream detector 200.

On the other hand, when screaming is detected during the scream detection waiting time, all various pieces of information are stored. That is, when scream is detected during the scream detection waiting time, the visitor image in the visitor call signal received during the door open detection waiting time and the scream detection waiting time is stored in the internal storage of the scream detector 200, and scream is detected. The ambient sound collected during the waiting time is implemented to be stored in the internal storage of the scream detector 200.
