Description

  The present invention relates to a crime prevention device that detects and alerts an intruder.

  The conventional security alarm device issues a warning from the speaker installed in the master unit in conjunction with the movement of the human body or object detected by the human body detection sensor (security device), or pays attention to the surroundings by the light emitter. Encouraged and monitored house intruders.

  For example, FIG. 9 is a configuration diagram schematically showing a security device. The crime prevention child machine 11 processes the human body detection sensor output from the pyroelectric sensor 12 with a microcomputer (not shown), and sends the human body detection information of the processing result to the parent machine 21 through the antenna.

  When the main unit 21 receives the human body detection information from the security device 11 in the security mode, the base unit 21 emits an alarm sound from the speaker 22 or causes the light emitter 23 to emit light. You may make it report to the notified destination through a telephone line etc.

  Further, when the human body detection information is received from the security device 11 when the base unit 2 is in the non-guard mode, the received human body detection information is ignored and no alarm sound is generated or the light emitter 23 is not lit. You may do it.

The main power consumption in such a wireless crime prevention child machine 11 occurs when the human body detection information is transmitted to the parent machine 21 at the time of human body detection.

  However, it is more convenient for the security devices that need to be installed in various places, and it is more convenient to cover the power supply with batteries, and the power consumption of the batteries must be reduced as much as possible. It is unrealistic to realize.

  The conventional security alarm device can only perform one-way communication from the security device to the parent device, so the security device only transmits the input from the sensor, and the parent device receives the communication from the security device. It was only. Therefore, since it is not accurately known whether or not the security device is being alerted, an alarm sound cannot be emitted from the security device.

  The present invention solves the above-described conventional problems, and can suppress whether or not there is an alarm sound from the security device while suppressing power consumption of the battery as a power source of the security device as much as possible. It is.

  In order to solve the above-described problems, the present invention detects a movement of a human body or an object by a wireless communication means for wirelessly reporting to a parent machine if there is an input of a sensor for detecting the movement of a human body or an object in the house. The wireless communication means is configured to receive a report from the master unit for a predetermined period after the report to the master unit is transmitted, so that the reception circuit current significantly increases. This saves energy and reduces battery consumption.

  The wireless security device of the present invention can switch whether or not an alarm sound is emitted from the security device in accordance with a warning mode input to the parent device.

  1st invention is the radio | wireless communication means which alert | reports to a main | base station by radio | wireless if there exists the input of the sensor which detects the motion of the human body or object in a house, and the alerting | reporting means which alert | reports that the motion of the human body or the object was detected by the sensor The wireless communication means is in a reception state in which the notification from the parent device can be received for a predetermined period after the notification to the parent device is transmitted, thereby greatly saving the receiving circuit current and reducing the battery power. It is possible to reduce wear and improve the responsiveness that can cancel the notification means (alarm etc.) at any time.

  According to a second aspect of the invention, in particular, in the first aspect of the invention, the wireless communication means moves the human body or the object by the sensor using the notification means if there is no return from the parent machine for a predetermined period after the notification to the parent machine is transmitted. Is detected, and when the alert mode is not known due to a failure or communication failure of the master unit, it becomes fail safe and the crime prevention effect is enhanced.

  According to a third aspect of the invention, in particular, in the first or second aspect of the invention, the power supply specifying means is provided, and when the power supply specifying means is specified as a built-in battery, a response from the parent machine is waited after transmitting to the parent machine The notification from the master unit can be received for a certain period of time, and when the supply power supply specifying means specifies the external power supply, it can always be received. According to this, you can cancel the alarm sound at any time while suppressing battery consumption with a single security device, and use the alarm device to emit an alarm sound when other security devices detect an abnormality. You can do it.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a configuration diagram of a wireless alarm device according to the first embodiment of the present invention. It consists of a parent device 30 and a security device 31 that can communicate bidirectionally wirelessly. In order to detect a house intruder, a plurality of security terminals 31 are installed at various places in the house.

  A device number is assigned to each of the security devices 31 so as to distinguish each device, and a communication message with the parent device 30 is performed by specifying the device number. The security device 31 has a built-in sensor 32 for detecting movement in the house or is connected to the outside. The sensor 32 is realized by a human sensor that detects a change of infrared rays to detect the passage of a person, an open / close sensor that closes a contact when a door / window is opened, and can detect the movement of a human body or an object. A gas leak sensor or a water leak sensor may be used.

  The security device 31 operates with the built-in battery 34 because it is easy to install. When there is a change in the input of the sensor 32, the wireless communication means 33 notifies the parent device 30 wirelessly. The security device 31 has an alarm means 35 that emits an alarm sound. However, since it is not known whether the sensor 32 has reacted by the movement of the person or the sensor 32 has reacted by the intruder in the house while the person is out, it is still at this stage. Does not alarm.

The parent machine 30 includes a warning mode input means 36 and a storage means 37 for storing the inputted warning mode state. FIG. 2 is a front view of the base unit 30, which is an operation board for inputting a warning mode. When the buttons 38A to 38C indicating the place to be warned are pressed, the LEDs 39A to 39C are turned on to indicate that the place is being warned. In order to move to the bedroom at night, the user presses a button to place the living room and the entrance in the alert mode, and the bedroom in the alert release mode. On the other hand, in the daytime, the bedroom is set in the alert mode. When the outing warning button 40 is pressed, all the LEDs 39A to 39C are lit and the entire house is on alert. However, since only the entrance is on the alert after leaving the house, it enters the alert mode after about 1 minute.

  When the warning release button 41 is pressed, all the LEDs 39A to 39C are turned off, and the home warning mode is released. A plurality of security devices 31 installed in advance are grouped in advance according to the installation location and stored in the storage means 37. Since the master unit is connected to the AC power source 42 and there is no fear of running out of the battery, it can always be received.

  When the base unit 30 receives a signal indicating that the input from the security device 31 has been changed by the wireless communication unit 43, the storage unit stores whether the location to which the security device 31 belongs is in the alert mode or the alert release mode. The wireless communication means 43 transmits the alarm sound from the alarm means 35 of the crime prevention child machine 31 so as to sound an alarm sound if it is in the alert mode, and does nothing in the alert release mode.

  At this time, if the security device 31 is at the entrance, in the case of the alert mode, an alarm reservation message is sent to sound an alarm sound after one minute. This is because the sensor reacts by opening the entrance door because the user has returned home from the outside, but the alert may be released at the parent machine 30. If the alert mode is canceled within one minute, an alarm canceling message is transmitted to the security device 31 so that no false alarm is required. Even if a warning sound is generated by opening a window without canceling the warning mode, if the warning mode is canceled by the main unit 30, an alarm canceling message can be immediately transmitted to the security device 31 to cancel the warning sound. According to this, power consumption of the battery mounted on the security device 31 can be suppressed while realizing communication from the parent device 30 to the security device 31.

  The above operation will be described again using the sequence diagram (FIG. 3). FIG. 3 shows a case where the entrance is set to the alert mode in the base unit 30 and the sensor is abnormal. The security device 31 at the entrance inputs a change in sensor input and transmits a “sensor input change message” 44. From this time, the security device is in a receiving state. The master unit 30 transmits a “warning reservation message” 45 indicating that an alarm sound is sounded after one minute because the entrance is in the alert mode because the entrance is in the alert mode. During this waiting time, the user operates the master unit 30 to cancel the warning mode. Therefore, the master unit 30 transmits an “alarm stop message” 46, and the security slave unit 31 performs a series of operations without sounding an alarm. End and stop receiving.

  FIG. 4 shows a remote controller 47 only for setting whether to enter the alert mode or cancel the alert mode for the base unit 30. Master unit 30 can change the alert mode not only with its own operation panel but also with this remote controller. For example, it is not necessary to go to the main unit 30 each time if the warning mode is set when leaving the entrance when going out, or the warning mode is canceled before the entrance is opened when returning home. Also, if you carry it around the house, you can stop the alarm sound on the spot even if there is a false alarm.

  Next, an example of the operation using the remote controller 47 will be described with reference to a sequence diagram (FIG. 5). When the bedroom is set in the alert mode in the master unit 30 and the sensor is abnormal, the security device 31 in the bedroom inputs a change in the sensor input and transmits a “sensor input change message” 48. From this time, the security device 31 is in a receiving state.

  The master unit 30 transmits from the crime prevention device 31 installed in the bedroom from the device number, and transmits an “alarm telegram” 49 that immediately sounds an alarm sound because the bedroom is in the alert mode. The security device 31 outputs an alarm sound from the alarm means and maintains the reception state. When the user operates the remote controller 47, a “warning release message” 50 is transmitted to the parent device 30, and when the warning mode of the parent device 30 is released, an “warning stop message” 51 is transmitted from the parent device 30, and the crime prevention child The machine 31 stops the alarm sound, ends the series of operations, and stops receiving.

  As described above, the operation of the security device 31 is performed in response to the security device when the security mode is changed in the system in which the security device 31 is constantly receiving by intermittent reception with a short period of time. Can also be realized.

  By the way, in order for the security device 31 to respond to communication from the main device 30 without causing the user to feel stress, it must continue to receive at intervals of 3 seconds at the longest. Most of it is spent on reception. Therefore, in order to operate the security device 31 with an alkaline battery or a small lithium battery for more than one year, a method for reducing battery consumption is required. Therefore, the wireless communication means 33 of the crime prevention child machine 31 transmits a notification to the parent machine 30 and waits for a reply from the parent machine 30 for a certain period of time, only during the waiting time for generating an alarm sound and during the generation of the alarm sound, By operating the receiving circuit to enter the receiving state, and thereafter not operating the receiving circuit, a significant battery saving can be achieved, and a good response that can cancel the alarm at any time can be achieved.

  Also, the security device 31 transmits a signal indicating that the input has changed, and generates a warning sound if there is no return from the parent device 30 within a certain time, so that the parent device fails or a communication failure occurs due to jamming radio waves. When the alert mode is not known and the alert mode is not known, the alarm can be made safe and the crime prevention effect can be enhanced.

(Embodiment 2)
FIG. 6 is a configuration diagram of the wireless alarm device according to the second embodiment of the present invention. The security device 52 has a plurality of power supply means. In addition to the built-in battery 34, there is a power supply terminal 53 that can supply power from the outside, and an AC adapter 54 can be connected. The power supply switching means 55 has supply power supply detection means 56.

  FIG. 7 is a circuit diagram of the power supply switching means 55. The diode 57 prevents the current from the built-in battery 34 and the current from the power supply terminal 53 from flowing back to each other. There is a power supply voltage detection means 58 on the power supply terminal side. Further, there is a power supply detection means 56 that determines that power is supplied from the outside when a voltage is detected. When the supplied power source is the built-in battery 34, after transmitting to the main unit, it is received only for a certain period of time waiting for a reply from the main unit 30 and a waiting time for generating an alarm sound and during the generation of the alarm sound. Do not receive the time to prevent battery drain.

  On the other hand, when operating with the AC adapter 54 of the external power source, it always waits to receive a transmission from the parent machine and sound an alarm sound at any time. When there are many rooms, the threatening effect is greater when the alarm sound is sounded in more places than when the alarm sound is sounded only by the crime prevention child device 52 and the parent device 30 that are abnormal.

  FIG. 8 is a sequence diagram of the operation. In response to the “sensor input change message” 59 from the security device A operating with the built-in battery, the parent device returns an “alarm message” 60 to the security device A, and subsequently transmits the “alarm message” 61 in a simultaneous broadcast. To do. Security device B running on an internal battery other than the security device A is not receiving, but the security device C operating on an external power supply receives an “alarm telegram” 61 and can determine the alarm sound in advance. Sounds for a certain period of time and threatens.

  As described above, the wireless alarm device according to the present invention can switch the presence / absence of an alarm sound from the security device according to the alert mode input to the master unit.
