Abstract

PROBLEM TO BE SOLVED: To solve the problems that the conventional safety confirmation device for a solitary person is too expensive because many devices have a telephone function with an alarm function including a pyroelectric sensor and that expense is required because a construction is needed to install a device.SOLUTION: An inexpensive product can be provided by adopting a simple system which includes a pyroelectric sensor to automatically measure a time after the behavior of a solitary person is not detected any more, and performs an alarm output only when a time elapses more than a time set in advance.

Description

  The present invention relates to an alarm device.

  Up until now, there were alarm devices using pyroelectric sensors for confirming the safety of single persons, but there are many alarm notification systems that have a telephone function, and they simply output only alarms. Does not exist.

  Previous single-person safety confirmation devices have been expensive, with many devices having a telephone function with an alarm function incorporating a pyroelectric sensor.

  In addition, construction may be necessary during installation, which is expensive.

  The present invention is inexpensive by adopting a simple system that incorporates a pyroelectric sensor and automatically measures the time since the movement of a single person is no longer detected and outputs a warning only when a preset time or more has elapsed. New products can be supplied.

  In addition, installation is not required, and it is only necessary to place it in a living room where there are single persons who need safety.

  The safety confirmation device with built-in pyroelectric sensor according to the present invention may be placed in a room where the number of single persons who need safety is the largest in the house, and connected in combination with a commercially available alarm device, light bulb, buzzer, etc. This makes it possible to provide inexpensive products without installation work.

  In addition, by connecting a safety confirmation device with a built-in pyroelectric sensor in combination with a commercially available light bulb or buzzer, etc., when the operation of a single person has exceeded the time set in advance by the program in the device, the light bulb is turned on or The buzzer will sound. By installing a light bulb or buzzer at the entrance, etc., it becomes possible to inform the surroundings that there was an abnormality in the single person.

  FIG. 1 shows a block diagram of a safety confirmation device (2) with a built-in pyroelectric sensor (1). Connect the AC outlet (3) to 100V and supply it to the power circuit (4). The pyroelectric sensor (1) generates a minute signal when it detects a human motion. The signal is amplified by the amplifier circuit (5) and converted by the comparator circuit (7) so that it can be input to the microcomputer (6). Since the signal does not change when no human movement is detected, the microcomputer (6) measures the time during which the signal does not change, and when the preset time is reached, an output signal is sent and the relay drive circuit (8) To operate the relay contact (9) to generate an output signal. When the user goes out for a long time or goes to bed, the switch is operated to stop the operation.

  FIG. 2 shows an example of the appearance of a safety confirmation device (2) with a built-in pyroelectric sensor (1). AC outlet (3) connected to AC100V, pyroelectric sensor (1) for detecting human movement, switch (10) for stopping operation when going out or sleeping for a long time, and LED lamp ( 11) and a terminal (12) for outputting an alarm signal.

  FIG. 3 shows an example of a combination of a pyroelectric sensor (1) built-in safety confirmation device (2) and a commercially available light bulb (13). A commercially available light bulb (13) and an outlet (14) are connected to a terminal (12) for outputting an alarm signal, and connected to AC100V. Connect the AC outlet (3) built in the pyroelectric sensor (1), release the switch (10) that stops the operation when going out for a long time or sleeping, and confirm that the LED lamp (11) is in operation. In this state, when the pyroelectric sensor (1) has not detected a human motion for a preset time, the commercially available light bulb (13) is turned on. By installing a commercially available light bulb (13) at the entrance, etc., it is notified that there was an abnormality in the surroundings.

Claims (3)

  Always install a device with a pyroelectric sensor in the room where the number of single-persons who need safety confirmation is the largest in the house, and when a single person's movement is detected, no alarm signal is output and the single person is alone A safety alarm device with a pyroelectric sensor that measures the time when it is not detected and outputs an alarm signal when the time set in advance by a program in the device has elapsed.   When a single person who needs to check safety at all times installs a device with a built-in pyroelectric sensor in the room where there are the most people in the house and does not output an alarm signal when detecting the movement of the single person, When the operation is not detected, the time not detected is measured, and when the time set in advance by the program in the device has elapsed, an alarm signal is output, and the alarm signal can be easily connected to a commercially available emergency telephone device. Safety alarm device with pyroelectric sensor that can be connected and can notify the appropriate destination when no single person is detected.   When a single person who needs to check safety at all times installs a device with a built-in pyroelectric sensor in the room where there are the most people in the house, the alarm device is not output when the single person's movement is detected. When the operation is not detected, the time not detected is measured, and when the set time set in advance by the program in the device has elapsed, an alarm signal is output. A safety confirmation device with a pyroelectric sensor that can be easily connected to a light source and can turn on a light bulb or sound a buzzer when no single person is detected.
