Upon the switching of the operation state, the monitoring device transmits a security start signal or a cancellation completion signal while adding information indicating power supply voltage or power supply voltage and a monitoring result to the signal. Based on the signal, the remote control device reports the operation result, a voltage drop in the monitoring device 30 and the monitoring result of the monitored area by voice. Also, when a user inputs a confirmation request, the monitoring device transmits the monitoring result (S340) and the remote control device reports the monitoring result by voice (S160).

Description

  The present invention relates to a security system that detects intrusion of a suspicious person into a predetermined monitoring target area such as a house, a monitoring device that configures the system, and a remote control device.

  Conventionally, a monitoring device that detects intrusion of a suspicious person into a monitoring target area has been provided with a human sensor for detecting the suspicious person, and a human (suspicious person) is detected by the human sensor. The control circuit performs a predetermined alarm operation (for example, generation of an alarm sound, notification of abnormality to a security company, etc.) (see, for example, Patent Documents 1 and 2).

  In addition, in this type of monitoring device, since the human sensor cannot identify a person, if the monitoring device is operating, even if a user of the monitoring device enters the monitoring target area, The user is detected by the human sensor, and the control circuit performs an alarm operation.

  For this reason, the monitoring device is provided with a remote control device for remote operation (hereinafter also referred to as a remote control device), and the operation / stop of the monitoring device is switched by remote operation when the user operates the remote control device. It is possible to do.

  As such a remote control device for remote control, a wireless remote control capable of notifying operation results is known (see, for example, Patent Document 3).

JP 2010-152777 A JP 2006-4040 A Japanese Patent Application Laid-Open No. 2002-252884

  According to the remote control device described in Patent Document 3, when a user performs a remote operation on a control target, an operation command is transmitted to the control target, and then an operation result transmitted from the control target is received and received. Since the voice representing the operation result is generated, the user can confirm the operation result by voice.

  For this reason, if a security system is configured by using this remote control device and the monitoring device, and the monitoring device can be remotely operated using the remote control device, the user can suspicious the monitoring device after operating the remote control device.

Then, a confirmation request transmission means for notifying the user of the monitoring result corresponding to the confirmation signal via the notification means,
It is provided with.

The invention according to claim 12 is the remote control device according to claim 10 or 11,
The remote control device has a built-in battery as a power source,
The notification means includes a speaker that receives power supply from the battery and notifies the reception information by voice,
The power supply path from the battery to the speaker is made of a semiconductor and is provided with a voltage drop means for generating a voltage drop when energized.

  According to the security system of the first aspect, in the remote control device, when the user inputs a warning command by operating the operation unit, the warning request transmission means sends a warning request signal from the second communication means to the monitoring device. To send.

  Then, on the monitoring device side, the warning request signal is received by the first communication means, and the warning start means activates the monitoring means. Further, the warning start means transmits a warning start signal indicating that the monitoring device has entered a warning state from the first communication means to the remote control device.

For this reason, on the remote control device side, when the warning request transmitting means transmits a warning request signal from the second communication means, the warning start signal is received by the second communication means.
And when a warning start signal is received by the 2nd communication means in this way, a warning request transmission means notifies a user that the monitoring apparatus was in a warning state via a notification means.

  Therefore, according to the security system of the present invention, when the user operates the operation unit of the remote control device and inputs a warning command, the user can confirm that the monitoring device has been switched to the warning state as a result of the operation. .

  Further, in the remote control device, when the user operates the operation unit to input a release command, the release request transmission unit transmits a release request signal from the second communication unit to the monitoring device.

  Then, on the monitoring device side, the cancellation request signal is received by the first communication unit, and the warning cancellation unit stops the operation of the monitoring unit. The warning canceling means reads out the monitoring result stored during the operation of the monitoring means, and gives the monitoring result to the cancellation completion signal indicating that the monitoring device has released the warning, from the first communication means. Send to remote control device.

For this reason, on the remote control device side, when the release request transmitting means transmits a release request signal from the second communication means, the release completion signal is received by the second communication means.
Then, when the release completion signal is received by the second communication means in this way, the release request transmission means reads the monitoring result given to the monitoring completion signal and sends the monitoring result to the user via the notification means. To inform.

  Therefore, according to the security system of the present invention, when the user inputs the release command by operating the operation unit of the remote control device, as a result of the operation, the monitoring device has released the warning state, The monitoring result in the alert state can be confirmed.

  Therefore, according to the security system of the present invention, the user prevents the monitoring device from entering the monitored area without releasing the alert state and not knowing that the suspicious person is detected by the monitoring device. It is possible to improve the safety of the user.

Next, in the security system according to the second aspect, monitoring confirmation means is provided in the monitoring device, and confirmation request transmission means is provided in the remote control device.
Then, in the remote control device, when the user inputs a confirmation command via the operation unit, the confirmation request transmission unit causes the second communication unit to transmit a confirmation request signal to the monitoring device.

  Then, on the monitoring device side, the confirmation request signal is received by the first communication means, and the monitoring confirmation means transmits the monitoring result stored by the monitoring means as a confirmation signal from the first communication means to the remote control device. .

  For this reason, on the remote control device side, when the confirmation request transmitting unit causes the second communication unit to transmit a confirmation request signal, the second communication unit receives a confirmation signal representing the monitoring result by the monitoring device. .

When the confirmation signal is received by the second communication unit in this way, the confirmation request transmission unit notifies the user of the monitoring result corresponding to the confirmation signal via the notification unit.
Therefore, according to the security system of the second aspect, only when the user inputs a release command by operating the operation unit of the remote control device (in other words, when monitoring by the monitoring device is stopped). Even when the confirmation command is input by operating the operation unit, the monitoring result by the monitoring device can be confirmed.

  Therefore, if the user is in a range where the transmission radio wave from the remote control device reaches the monitoring device, the remote control device can be used at any time even if the monitoring device is in a warning state or in a warning release state. As a result, it becomes possible to check the monitoring result by the monitoring device, so that the usability of the remote control device can be improved and the safety of the user can be further improved.

  As described in claim 2, when the user can check the monitoring result by the monitoring device by operating the operation unit of the remote control device and inputting the confirmation command, the warning of the monitoring device is canceled. The means may be configured as described in claim 3.

  That is, in the security system according to claim 3, the warning canceling means of the monitoring device is configured such that the monitoring confirmation means transmits the monitoring result as a confirmation signal from the first communication means after the monitoring device enters the warning state. Prohibits the monitoring result from being added to the release completion signal.

  That is, when the user confirms the monitoring result by inputting a confirmation command from the operation unit of the remote control device before the monitoring device is released from the warning state, the monitoring device is released from the warning state. In this case, since it is not necessary to notify the monitoring result, unnecessary transmission of the monitoring result is prohibited.

And even if it does in this way, since the user can confirm the monitoring result by a monitoring apparatus as needed, it can acquire the effect similar to the security system of Claim 2.
Next, in the security system according to the fourth aspect, the monitoring device is provided with a displacement sensor that detects that the monitoring device has been moved.

  When the monitoring device is in the monitoring state, the monitoring means not only operates the human sensor to monitor the intrusion of the suspicious person into the monitoring target area, but also operates the displacement sensor to move the monitoring device. Monitoring is performed, and both of these monitoring results are stored as monitoring results to be transmitted to the remote control device.

  As a result, when the user inputs a release command or confirmation command by operating the operation unit on the remote control device side, the user is not limited to the detection result of the suspicious person by the human sensor as the monitoring result. The detection result of the movement of the monitoring device by the sensor is also notified.

  Therefore, according to the security system of the fourth aspect, in order for the suspicious person to avoid detection by the human sensor, the user enters from behind the monitoring device (in other words, the direction away from the monitoring target area). Even when the monitoring device is moved, this can be detected by operating the remote control device.

  By the way, the remote control device starts the monitoring device when the user leaves the monitoring target area by the monitoring device, and stops the monitoring by the monitoring device when the user enters the monitoring target area. For this purpose, it is necessary to incorporate a battery as a power source in the remote control device.

  In addition, if the notification means notifies the user of the monitoring result with a notification sound that can identify the monitoring result or a sound such as a sound, the user can easily detect the monitoring result. In this case, if power is directly supplied from the battery to the speaker in order to generate sound, it is considered that the power supply voltage decreases due to the current that flows when the speaker rings, affecting the operation of other components. .

  Thus, when the remote control device has a built-in battery as a power source, and the notification means includes a speaker that receives power supply from the battery and notifies the reception information by voice, As described in 5, the voltage drop means made of a semiconductor is provided on the power supply path from the battery to the speaker so as to suppress the power supply voltage drop.

  In this way, it is possible to prevent other components from stopping operation or becoming in an abnormal operation state due to a decrease in power supply voltage. In this way, since the power consumption of the battery can be reduced, the life of the battery can be extended.

Next, the invention described in claims 6 to 9 is an invention relating to a monitoring device suitable for realizing the security system of the present invention.
And the monitoring apparatus of Claim 6 is equipped with the 1st communication means, the monitoring means, the warning start means, and the warning cancellation | release means like the thing of Claim 1.

  Further, the monitoring device according to claim 7 is provided with monitoring confirmation means, similar to that according to claim 2. For this reason, according to the monitoring device of the seventh aspect, the security system according to the second aspect can be constructed to obtain the same effect as the second aspect.

  Further, in the monitoring device according to claim 8, the warning release means operates in the same manner as that according to claim 3. For this reason, according to the monitoring device of the eighth aspect, the security system according to the third aspect can be constructed to obtain the same effect as the third aspect.

  Further, the monitoring device according to claim 9 is provided with a displacement sensor as in the case of claim 4, and the monitoring means operates in the same manner as in the case of claim 4. For this reason, according to the monitoring device of the ninth aspect, the same effect as that of the fourth aspect can be obtained by constructing the security system according to the fourth aspect.

Next, the invention described in claims 10 to 12 is an invention relating to a remote control device suitable for realizing the security system of the present invention.
The remote control device according to claim 10 includes an operation unit, second communication means, notification means, warning request transmission means, and release request transmission means, as in the first aspect.

Embodiments of the present invention will be described below with reference to the drawings.
The security system according to the present embodiment is installed in a desired room in a building such as a house or office, and detects a suspicious person who has entered the room, and a user monitors the building from outside the building. A remote control device (remote control device) 30 for instructing start / stop of the device 10 is configured.

  FIGS. 1A-1 and 1A-2 are a front view and a side view showing the appearance of the monitoring device 10, and FIGS. 1B-1 and 1B-2 show the appearance of the remote control device 30. It is a front view and a side view. 2A is a block diagram illustrating a circuit configuration of the monitoring device 10, and FIG. 2B is a block diagram illustrating a circuit configuration of the remote control device 30.

  As shown in FIGS. (A-1) and (a-2), the monitoring device 10 houses various components shown in FIG. 2 (a) in a housing that can be installed on a shelf or a desk. The operation switch 12, the display panel 14, the display lamp 16, and the human sensor 18 are provided on the front surface of the housing.

  In addition, as shown in FIGS. 1B-1 and 1B-2, the remote control device 30 can be operated by being held by a user and can be carried in a portable case as shown in FIG. The operation switch 32 including a warning / confirmation switch 32a and a release switch 32b is provided on the front surface of the housing. In addition, a hole for releasing sound from the internal speaker 34 to the outside of the housing is formed in the front surface of the housing.

  In the monitoring device 10, the operation switch 12 includes a main switch and up / down selection key switches arranged on both sides thereof, and the user displays a menu on the display panel 14 and selects a desired item. By doing so, the operation setting of the monitoring apparatus 10 and confirmation of the monitoring result are performed.

  The display panel 14 is for displaying various information with characters and symbols, and is composed of a liquid crystal display panel. Moreover, the display lamp 16 is comprised from LED, for example, is utilized for alerting | reporting that the battery remaining charge of the power supply part 28 fell.

  Next, the human sensor 18 is for detecting an intruder into the monitoring target area with the periphery of the front side of the monitoring device 10 as a monitoring target area, and is configured by a known pyroelectric sensor. Yes.

  In addition to the pyroelectric sensor that detects the movement of a person with light including infrared rays, the human sensor 18 uses an ultrasonic sensor that detects a person using ultrasonic waves, or both infrared rays and ultrasonic waves. Thus, a sensor for detecting a person can be used. That is, the human sensor 18 may be any sensor that can detect the intrusion of a suspicious person.

The monitoring device 10 includes a control unit 20, a displacement sensor 22, an antenna 24, and a wireless communication unit 26 in addition to a power supply unit 28 made of a battery.
The displacement sensor 22 is for detecting that the monitoring device 10 has been moved by an intruder, and is composed of a biaxial or triaxial acceleration sensor or an angular velocity sensor (so-called gyro sensor). The displacement sensor 22 may be a ball sensor that includes a ball-shaped weight and detects the movement of an object by the movement of the weight.

  The antenna 24 and the wireless communication unit 26 are for performing wireless communication using radio waves with the remote control device 30. The wireless communication unit 26 can perform wireless communication as long as the communication channel (frequency / modulation method) is the same, but the control unit 20 has the ID of the remote control device 30 capable of wireless communication with the monitoring device 10. The communication devices registered in advance and performing wireless communication by the wireless communication unit 26 are limited to one or a plurality of remote control devices 30 registered in advance.

Next, the control part 20 is comprised with the microcomputer (microcomputer) which consists of CPU, ROM, RAM, etc., and each said part is connected.
The control unit 20 operates in accordance with a command input from the operation switch 12 or the remote control device 30. For example, when a warning request signal transmitted from the remote control device 30 is received by the wireless communication unit 26, the human sensor 18 and the displacement sensor 22 are operated to enter a warning state where the intrusion of the suspicious person and the movement of the monitoring apparatus 10 itself are monitored.

  In addition, when the release request signal transmitted from the remote control device 30 is received by the wireless communication unit 26, the control unit 20 stops the operation of the human sensor 18 and the displacement sensor 22 to release the warning state, and wirelessly When the confirmation request signal transmitted from the remote control device 30 is received by the communication unit 26, the monitoring result by the human sensor 18 and the displacement sensor 22 (in other words, the suspicious person and the movement by the human sensor 18 and the displacement sensor 22). Is detected from the memory (RAM) and transmitted from the wireless communication unit 26 to the remote control device 30.

The power supply unit 28 is for supplying a DC voltage Vcc to each of the above-described units, and operates by receiving power supply from a battery.
On the other hand, in the remote control device 30, the warning / confirmation switch 32 a transmits a warning request signal or a confirmation request signal from the remote control device 30 to the monitoring device 10 when the user inputs a warning command or a confirmation command to the remote control device 30. The content of the command from the user is identified based on the pressing time of the warning / confirmation switch 32a.

  In other words, in this embodiment, when the pressing time of the warning / confirmation switch 32a exceeds the set time T1 (for example, 2 seconds), it is determined that the user has input a warning command, and a warning request signal is transmitted. If the pressing time of the switch 32a is equal to or shorter than the set time T1, it is determined that the user has input a confirmation command and a confirmation request signal is transmitted.

  The release switch 32 b is for causing the remote control device 30 to transmit a release request signal to the monitoring device 10 when the user inputs a release command to the remote control device 30.

  In the present embodiment, when the pressing time of the release switch 32b exceeds a set time T2 (for example, 2 seconds), it is determined that the user has input a release command, a release request signal is transmitted, and the warning / confirmation switch 32a If the pressing time is equal to or less than the set time T1, it is determined that the release command has not been input, and transmission of the release request signal to the monitoring device 10 is prohibited.

  Next, the remote control device 30 includes a speaker 34, a sound amplifying unit 36 that outputs a sound signal to the speaker 34 to generate sound, and a control unit 40 configured by a microcomputer including a CPU, a ROM, a RAM, and the like. In addition, an antenna 44 and a wireless communication unit 46 for performing radio communication with the monitoring apparatus 10 using radio waves, and a power supply unit 48 for supplying power to each of the above units are incorporated.

The control unit 40 operates in accordance with commands input from the warning / confirmation switch 32a and the release switch 32b that constitute the operation switch 32.
That is, the control unit 40 transmits each of the request signals to the monitoring device 10 via the wireless communication unit 46 in accordance with a command input from each of the switches 32 a and 32 b, and then a response transmitted from the monitoring device 10. Based on signals (a warning start signal, history confirmation signal, and release completion signal described later), an operation result from the speaker 34 and a monitoring result on the monitoring device 10 side (suspicious person and movement detection history by the human sensor 18 and displacement sensor 22) ) Is generated and output to the audio amplifying unit 36, thereby generating audio representing the operation result and the detection history from the speaker 34.

  In addition, each of the above components constituting the remote control device 30 operates by receiving power supply from the battery constituting the power supply unit 48. However, since the battery that can be built into the portable remote control device 30 is small, the battery capacity is also small. When power is supplied from the power supply unit 48 to the speaker 34, it is considered that the power supply voltage decreases due to the current that flows when the speaker 34 rings and affects the operation of each unit including the control unit 40.

  Therefore, in the present embodiment, a pair of diodes D1 and D2 shown in FIG. 3A or a pair of diodes D1 and D2 shown in FIG. 3A on the power supply path from the power supply line of the DC power supply (voltage Vcc) to the speaker 34 is shown. By providing the voltage drop means 50 composed of the Zener diode ZD1 and the transistor TR2, it is possible to prevent a drop in the power supply voltage that occurs when the speaker 34 rings, and the control unit 40 and other circuits stop operating due to the drop in the power supply voltage. To prevent abnormal operation.

  3A and 3B, the resistors R1 and R2 and the transistor TR1 are the audio amplifying unit 36. The audio amplifying unit 36 converts the audio signal output from the control unit 20 into the resistors R1 and R1. The audio signal is amplified by inputting to the transistor TR1 via the resistor R2, and the speaker 34 is caused to ring by flowing the amplified audio signal to the speaker 34.

  And the voltage drop means 50 is provided on the path | route of the audio | voice signal which flows into the speaker 34 from a power supply line, and in the thing of Fig.3 (a), the forward voltage drop (about 0.7V) of the diode D1. A voltage drop is generated by the amount. Therefore, in FIG. 3A, in order to increase the voltage drop due to the voltage drop means 50, a plurality of diodes D1 may be connected in series.

  In FIG. 3 (a), the diode D2 is connected in parallel with the diode D1 with the polarity reversed, but this causes a current to flow to the power supply line when a reverse voltage is generated in the speaker 34. Is for.

  3B, the transistor TR2 includes an NPN transistor having a collector connected to the power supply line, an emitter connected to the speaker 34, and a Zener diode ZD1 connected between the base and the collector. It is composed of.

The Zener diode ZD1 has an anode connected to the base of the transistor TR2 and a cathode connected to the collector of the transistor TR2.
For this reason, in the voltage drop means 50 shown in FIG.3 (b), the voltage drop according to the breakdown voltage of Zener diode ZD1 generate | occur | produces.

  Next, FIG. 4 to FIG. 7 show control processes executed by the control unit 40 of the remote control device 30 and the control unit 20 of the monitoring device 10 when the user operates the operation switch 32 on the remote control device 30 side. It is a flowchart to represent.

  As shown in FIG. 4A, in the control unit 40 of the remote control device 30, in order to determine that the user has operated the operation switch 32, first in S110 (S represents a step), warning / confirmation is performed. It is determined whether or not the switch 32a has been pressed. If the warning / confirmation switch 32a has not been pressed, the process proceeds to S170 to determine whether or not the release switch 32b has been pressed, and the release switch 32b has been pressed. If not, the process waits for any one of the operation switches 32 to be pressed in a procedure such as once ending the control process and proceeding to S110 again.

  When it is determined in S110 that the warning / confirmation switch 32a has been pressed, in S120, for example, an operation sound of "P" is generated from the speaker 34, and then the process proceeds to S130, where the warning / confirmation switch 32a It is determined whether or not the pressing time has exceeded the set time T1 described above.

  If it is determined in S130 that the time for pressing the warning / confirmation switch 32a exceeds the set time T1, for example, in S140, an operation sound of “pippy” is generated from the speaker 34, and then the process proceeds to S150. 5 is executed. Then, when the warning request transmission process is executed, the control process is once ended, and the process proceeds to S110 again.

  In S130, if it is determined that the pressing time of the warning / confirmation switch 32a does not exceed the set time T1, the process proceeds to S160, and the confirmation request transmission process shown in FIG. 6 is executed. When the confirmation request transmission process is executed, the control process is temporarily terminated, and the process proceeds to S110 again.

  Next, when it is determined in S170 that the release switch 32b is pressed, in S180, for example, an operation sound of “Piece” is generated from the speaker 34, and then the process proceeds to S190, where the release switch 32b is pressed. It is determined whether or not the set time T2 described above has been exceeded.

  If the depressing time of the release switch 32b does not exceed the set time T2, the control process is terminated once and the process proceeds to S110 again. Conversely, the depressing time of the release switch 32b exceeds the set time T2. For example, in S200, for example, an operation sound “Pippy” is generated from the speaker 34, and then the process proceeds to S210, and the release request transmission process shown in FIG. 7 is executed. Then, when the release request transmission process is executed, the control process is temporarily ended, and the process proceeds to S110 again.

  In contrast, the control unit 20 of the monitoring device 10 determines whether or not a remote control signal (specifically, any one of a warning request signal, a confirmation request signal, and a release request signal) has been transmitted from the remote control device 30. First, in S310, the wireless communication unit 26 determines whether or not a remote control signal transmitted from the previously registered remote control device 30 is received, and waits for reception of the remote control signal.

  If it is determined in S310 that a remote control signal has been received, in S320, the received remote control signal is identified as a warning request signal, a confirmation request signal, or a release request signal, and the remote control signal is identified. If the signal is a warning request signal, the process proceeds to S330 and the warning start process shown in FIG. 5 is executed.

  If the remote control signal is a confirmation request signal, the process proceeds to S340, and the confirmation process shown in FIG. 6 is executed. If the remote control signal is a release request signal, the process proceeds to S350, and the warning cancellation shown in FIG. Execute the process.

Then, after executing the processes of S330 to 350, the control process is temporarily terminated, and the process proceeds to S310 again.
Next, a warning request transmission process and a warning start process executed by the control unit 40 of the remote control device 30 and the control unit 20 of the monitoring device 10 will be described using the flowchart shown in FIG.

As shown in FIG. 5, in the alert request transmission process, first, in S410, the alert request signal is transmitted from the wireless communication unit 46 to the monitoring device 10.
Then, the warning request signal is received by the wireless communication unit 26 of the monitoring device 10, and a warning start process is executed on the monitoring device 10 side.

  In this warning start process, the detection history stored in the previous warning state is reset in S510, and the human sensor 18 and the displacement sensor 22 are activated in S520. , 22 (monitoring start).

  When the monitoring device 10 enters the monitoring state in this way, the power supply voltage (in other words, battery voltage) Vcc supplied from the power supply unit 28 is confirmed (detected) in S530, and the detection result is obtained in S540. A warning start signal including (power supply voltage) is generated and transmitted from the wireless communication unit 26 to the remote control device 30 that has transmitted the warning request signal.

  For this reason, in the alert request transmission process executed on the remote control device 30 side, whether or not the alert start signal transmitted from the monitoring device 10 is received by the wireless communication unit 46 during the predetermined standby time in S420. If a warning start signal is received, the process proceeds to S440, and the monitoring device 10 enters a warning state by generating, for example, a sound “warning has started” from the speaker 34. The user is notified.

  On the other hand, if it is determined in S420 that the warning start signal is not received, the process proceeds to S422, the transmission output from the wireless communication unit 46 is maximized, and the warning request signal is retransmitted from the wireless communication unit 46. Let

  Then, after retransmitting the warning request signal, in S424, it is determined whether or not the warning start signal transmitted from the monitoring device 10 is received by the wireless communication unit 46 during the predetermined standby time. If the start signal has been received, the process proceeds to S440 to provide voice guidance that the monitoring device 10 has entered the alert state.

  In S424, if it is determined that the warning start signal is not received, it is determined that some abnormality has occurred, such as a communication failure between the remote control device 30 and the monitoring device 10, a failure of the monitoring device 10, and the like. The process proceeds to S430, and the user is notified that communication with the monitoring apparatus 10 cannot be normally performed by generating a voice indicating communication failure such as “cannot communicate with the sensor” from the speaker 34. Then, after voice guidance in S430, the process proceeds to S470.

  Next, when the warning start is voice-guided in S440, the process proceeds to S450, and the power supply voltage (hereinafter referred to as a sensor) on the monitoring device 10 side given to the warning start signal transmitted from the monitoring device 10 is transferred. It is determined whether or not the sensor voltage is decreased by determining whether or not the voltage is lower than a preset decrease determination value V1.

  If it is determined in S450 that the sensor voltage has decreased, the process proceeds to S460, and a sound such as “Please replace the sensor battery” is generated from the speaker 34, for example. The user is informed that the battery level (sensor battery level) of the monitoring device 10 is low and the monitoring device 10 may not operate normally, and the process proceeds to S470. If it is determined in S450 that the sensor voltage has not decreased, the process proceeds to S470 as it is.

  Next, in S470, the remote control voltage is determined by determining whether or not the power supply voltage (in other words, the battery voltage) Vcc supplied from the power supply unit 48 to the control unit 40 is lower than a preset decrease determination value V2. It is determined whether or not the value has decreased.

  If it is determined in S470 that the remote control voltage has decreased, the process proceeds to S480, and a sound such as "Please replace the remote control battery" is generated from the speaker 34. The user is notified that the battery level of the remote control device 30 (remote control battery level) is low and the remote control device 30 may not operate normally, and the warning request transmission process ends.

  If it is determined in S470 that the remote control voltage has not decreased, the warning request transmission process is terminated. After this process is completed, the process proceeds to S110 in FIG.

  Next, in the alert start process executed on the monitoring device 10 side, after the alert request signal is transmitted from the wireless communication unit 26 in S540, the remote controller transmitted from the remote control device 30 by the wireless communication unit 26 is then performed. Until the signal is received, the processes of S550 to S580 are repeatedly executed.

  In the processing of S550 to S580, the detection state by the human sensor 18 and the displacement sensor 22 is monitored, and when a suspicious person enters or the movement of the monitoring device 10 is detected, the detection result is stored in the memory as a detection history. It is a process to do.

  That is, in S550, it is confirmed whether or not a detection signal of a suspicious person is input from the human sensor 18, and in S560, whether or not a detection signal indicating that the remote control device 30 has moved is input from the displacement sensor 22. In S570, when the input of the detection signal is confirmed in S550 or S560, the detection result indicating the type of the detection signal (that is, the intrusion of the suspicious person or the movement of the monitoring device 10) and the detection time are stored in the memory ( The detection history is updated (added) by writing to the RAM.

  In subsequent S580, the wireless communication unit 26 determines whether or not the remote control signal transmitted from the remote control device 30 is received. If no remote control signal is received, the process goes to S550 again, and the remote control signal is received. If so, the warning start process is terminated, and the process proceeds to S320 in FIG.

Next, a confirmation request transmission process and a confirmation process executed by the control unit 40 of the remote control device 30 and the control unit 20 of the monitoring device 10 will be described using the flowchart shown in FIG.
As shown in FIG. 5, in the confirmation request transmission process, first, in S <b> 610, a confirmation request signal is transmitted from the wireless communication unit 46 to the monitoring device 10.

Then, the confirmation request signal is received by the wireless communication unit 26 of the monitoring device 10, and confirmation processing is executed on the monitoring device 10 side.
In this confirmation process, first, in S710, the detection history stored in the memory (RAM) is confirmed, and in S720, the current time is confirmed. In subsequent S730, a history confirmation signal indicating the detection history and the current time obtained by the confirmation is generated, and the wireless communication unit 26 transmits the confirmation request signal to the remote control device 30 that has transmitted the confirmation request signal.

  In S730, after the history confirmation signal is transmitted from the wireless communication unit 26, the fact that the history confirmation signal is transmitted to the remote control device 30 is stored in S740, and then the process proceeds to S750. 10 determines whether it is in the alert state.

  If the monitoring device 10 is in a warning state, the confirmation process is terminated, and the process proceeds to S550 to S580 repeatedly executed in the warning start process shown in FIG. If it is not in the alert state (in other words, if it is in the alert release state), the confirmation process is terminated, and the process proceeds to S310 in FIG.

  As described above, when a confirmation request signal is transmitted from the remote control device 30 to the monitoring device 10, a history confirmation signal is transmitted from the monitoring device 10 to the remote control device 30. Therefore, in the confirmation request transmission process executed on the remote control device 30 side, After the confirmation request signal is transmitted in S610, it is determined in S620 whether or not the history confirmation signal transmitted from the monitoring apparatus 10 is received by the wireless communication unit 46 during a predetermined standby time.

  Then, when the history confirmation signal is received, the process proceeds to S640, and a voice message corresponding to the history confirmation signal is generated from the speaker 34 to notify the user of the monitoring result by the monitoring device 10, The confirmation request transmission process ends.

  In S640, if there is no intruder or movement detection history, for example, a voice message such as “sensor does not respond” is generated, and the detection time and current time of the intruder by human sensor 18 are detected. If the difference is short (for example, less than a few minutes), a voice message such as “Peepy” or “Sensor is responding” is generated. In addition, if the difference between the intruder detection time by the human sensor 18 and the current time is long (for example, several minutes or more), a voice message such as “Peep” or “Sensor has responded” is generated. If there is a detection history of the movement of the monitoring device 10 by the displacement sensor 22, a voice message such as “Peep” or “Sensor is being moved” is generated.

  On the other hand, if it is determined in S620 that the history confirmation signal is not received, the process proceeds to S622, and the transmission output from the wireless communication unit 46 is maximized, and the confirmation request signal is retransmitted from the wireless communication unit 46. Let

  Then, after retransmitting the confirmation request signal, in S624, it is determined whether or not the history confirmation signal transmitted from the monitoring apparatus 10 is received by the wireless communication unit 46 during the predetermined standby time. If the confirmation signal has been received, the process proceeds to S640, where the voice message corresponding to the history confirmation signal is generated from the speaker 34, thereby notifying the user of the monitoring result by the monitoring device 10 and transmitting the confirmation request. End the process.

  If it is determined in S624 that the history confirmation signal has not been received, it is determined that an abnormality such as a communication failure has occurred with the monitoring apparatus 10, and the process proceeds to S630. By generating a voice indicating communication failure such as “cannot communicate with the sensor”, the user is notified that communication with the monitoring apparatus 10 cannot be performed normally, and the confirmation request transmission process is terminated. Note that after the voice guidance in S630 or S640, the process proceeds to S110 in FIG.

  Next, a cancellation request transmission process and a warning cancellation process executed by the control unit 40 of the remote control device 30 and the control unit 20 of the monitoring device 10 will be described using the flowchart shown in FIG.

As shown in FIG. 5, in the cancellation request transmission process, first, in S810, the wireless communication unit 46 transmits a cancellation request signal to the monitoring device 10.
Then, the release request signal is received by the wireless communication unit 26 of the monitoring device 10, and the warning release processing is executed on the monitoring device 10 side.

  In this warning cancellation process, in S910, the confirmation process shown in FIG. 6 is executed after the monitoring device 10 enters the warning state until the warning cancellation process is started, and the history confirmation signal is displayed. It is determined whether or not is transmitted.

  If the history confirmation signal has been transmitted, the process proceeds to S930. If the history confirmation signal has not been transmitted, the process proceeds to S920, where the detection history stored in the memory (RAM) is confirmed, and the process proceeds to S930. Transition.

In S930, by stopping the operation of the human sensor 18 and the displacement sensor 22, the monitoring operation using these sensors 18 and 22 is stopped (warning release).
In subsequent S940, the power supply voltage (battery voltage) Vcc supplied from the power supply unit 28 to the control unit 20 is confirmed, and in S950, the detection result (power supply voltage) and the detection history confirmed in S920 are included. A cancellation completion signal is generated and transmitted from the wireless communication unit 26 to the remote control device 30 that has transmitted the cancellation request signal.

  For this reason, in the release request transmission process executed on the remote control device 30 side, whether or not the release completion signal transmitted from the monitoring device 10 is received by the wireless communication unit 46 during the predetermined standby time in S820. If the release completion signal is received, the process proceeds to S840. If the release completion signal is not received, the process proceeds to S822, and the transmission output from the wireless communication unit 46 is maximized. The cancel request signal is retransmitted from the wireless communication unit 46.

  Then, after re-transmission of the release request signal, in S824, it is determined whether or not the release completion signal transmitted from the monitoring apparatus 10 is received by the wireless communication unit 46 during the predetermined standby time. If the completion signal has been received, the process proceeds to S840, and if the release completion signal has not been received, the process proceeds to S830.

  In S830, the speaker 34 notifies the user that communication with the monitoring apparatus 10 cannot be normally performed by generating a voice indicating communication failure such as “cannot communicate with the sensor” from the speaker 34. The process proceeds to S880.

  Next, in S840, it is determined whether or not a detection history is given to the release completion signal transmitted from the monitoring device 10, and if a detection history is given to the release completion signal, the process proceeds to S850, By generating a voice message corresponding to the detection history given to the cancellation completion signal, the monitoring result by the monitoring device 10 is notified to the user, and the process proceeds to S860. In S850, the voice message generated corresponding to the detection history is the same voice message as in S640 described above.

  In subsequent S860, for example, by generating a sound “released” from the speaker 34, the user is notified that the monitoring device 10 has released the warning state, and the process proceeds to S870.

  Next, in S870, as in S450 described above, it is determined whether the sensor voltage has decreased. If the sensor voltage is lowered, the process proceeds to S880, and the speaker 34 generates a sound such as “Please replace the battery of the sensor”, thereby allowing the user to monitor 10 Is notified that the remaining battery level (sensor battery level) is low.

  If the process of S880 is executed or if it is determined in S870 that the sensor voltage has not decreased, the process proceeds to S890, and whether or not the remote control voltage is decreased as in S470 described above. to decide.

  If the remote control voltage is lowered, the process proceeds to S895, and a sound such as “Please replace the battery of the remote control” is generated from the speaker 34, so that the user can control the remote control device 30. Notify that the battery level (remote control battery level) is low.

  Then, the process of S895 is executed, or if it is determined in S890 that the remote control voltage has not decreased, the cancel request transmission process is terminated, and the process proceeds to S110 in FIG.

  As described above, according to the security system of the present embodiment, when the user inputs a warning command or a release command by long pressing the warning / confirmation switch 32a or the release switch 32b in the remote control device 30, the remote control device A warning request signal or a release request signal is transmitted from 30 to the monitoring device 10, and the operation state of the monitoring device 10 is switched from the warning release state to the warning state or vice versa.

  When the monitoring device 10 switches the operation state, a warning start signal including the sensor voltage or a release completion signal including the sensor voltage and the monitoring result (detection history) in the monitoring state is transmitted from the monitoring device 10 to the remote control device. 30.

  Then, on the remote control device 30 side, based on the warning start signal or release completion signal, in addition to the sound indicating that the switching of the operating state of the monitoring device 10 is completed, the sensor voltage and the monitoring result ( Based on the detection history, a sound indicating a decrease in sensor voltage or a monitoring result is output from the speaker 34.

  For this reason, when the user operates the remote control device 30 to switch the operation state of the monitoring device 10, the user can not only check the switching state on the monitoring device 10 side but also check the battery voltage on the monitoring device 10 side. Decrease (in other words, necessity of battery replacement) and monitoring results can be confirmed.

  Therefore, according to the security system of the present embodiment, the user enters the monitoring target area without knowing that the monitoring device 10 has detected the suspicious person after canceling the warning state of the monitoring device 10. Can be prevented and the safety of the user can be improved.

  Further, in the remote control device 30, if the user presses the warning / confirmation switch 32a for a short time, a confirmation request signal is transmitted from the remote control device 30 to the monitoring device 10, and the monitoring device 10 is in a monitoring state. Or, even in the monitoring state, the past monitoring result (detection history) is transmitted to the remote control device 30 as a history confirmation signal.

Then, on the remote control device 30 side, a voice message indicating the monitoring result is output from the speaker 34 based on the history confirmation signal.
For this reason, the user can enter the confirmation command to the remote control device 30 by operating the warning / confirmation switch 32a at any time within the range in which the transmission radio wave reaches the monitoring device 10 from the remote control device 30. The monitoring result can be confirmed.

Therefore, according to the present embodiment, the usability of the remote control device 30 can be improved and the safety of the user can be improved.
Further, the monitoring device 10 of the present embodiment is provided with a displacement sensor 22 for detecting that the monitoring device 10 has been moved by the suspicious person, in addition to the human sensor 18 for detecting the suspicious person. The detection result by the displacement sensor 22 is also transmitted from the monitoring device 10 to the remote control device 30 as a detection history.

  Therefore, for example, even if a suspicious person enters from behind the monitoring device 10 and moves the monitoring device 10 in order to avoid detection by the human sensor 18 visible from the outside of the monitoring device 10, the user This can be confirmed by operating the remote control device 30.

Therefore, according to the security system of the present embodiment, the safety of the user can be improved also by the detection history by the displacement sensor 22.
Further, in the present embodiment, in the remote control device 30, the voltage drop means 50 configured using the diode D1 or the Zener diode ZD1 is provided on the power supply path from the power supply line to the speaker 34. When the speaker 34 is ringed for guidance, it is possible to prevent the power supply voltage Vcc from being significantly reduced and the operation of the control unit 40 and the like from being stopped or abnormal.

  In this embodiment, the antenna 24 and the wireless communication unit 26 provided in the monitoring device 10 correspond to the first communication means of the present invention, and the antenna 44 and the wireless communication unit 46 provided in the remote control device 30 are The audio amplifying unit 36 and the speaker 34 provided in the remote control device 30 correspond to the second communication unit of the present invention, and correspond to the notification unit of the present invention.

  Moreover, the warning start process shown in FIG. 5 among the control processes executed by the control unit 20 of the monitoring device 10 corresponds to the warning start means of the present invention, and after the warning start signal is transmitted in the warning start process. The processes of S550 to S580 that are repeatedly executed correspond to the monitoring means of the present invention. Moreover, the warning cancellation | release process shown in FIG. 7 is corresponded to the warning cancellation | release means of this invention, and the confirmation process shown in FIG. 6 is equivalent to the monitoring confirmation means of this invention.

  Of the control processes executed by the control unit 40 of the remote control device 30, the warning request transmission process shown in FIG. 5 corresponds to the warning request transmission means of the present invention, and the release request transmission process shown in FIG. Corresponds to the cancellation request transmission means of the present invention, and the confirmation request transmission processing shown in FIG. 6 corresponds to the confirmation request transmission means of the present invention.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various aspect can be taken in the range which does not deviate from the summary of this invention.
(Modification of remote control device)
For example, in the above-described embodiment, the remote control device 30 has been described as having two operation switches, ie, a warning / confirmation switch 32a and a release switch 32b, as the operation switches 32. However, it is only necessary that a warning command, a confirmation command, and a release command can be input to the remote control device 30, so that three operation switches may be provided corresponding to each command, or two operation switches are used. The input method of each command may be set differently from the above embodiment.

  Further, for example, in the remote controller 30, when the user operates the two operation switches 32a and S32b at the same time, the control unit 40 may output an alarm sound from the speaker 34 during the operation or for a certain period of time. Good.

  And if it does in this way, remote control device 30 can be used as a security buzzer, and the use of remote control device 30 can be expanded. In this case, the operation method of the operation switch may be set as appropriate.

  Further, in the remote control device 30, the notification of the monitoring result (detection history) to the user is not a notification using sound or voice, but a notification by light using an LED or the like, or a notification by vibration using a vibration element such as a vibrator. , Or may be used to combine these notifications.

  In addition, the remote control device 30 can perform wireless communication using radio waves with the monitoring device 10 and can be carried by the user. You may make it incorporate in another portable communication apparatus.

If the portable communication device can realize various functions by writing application software in the memory, application software for realizing the function as the remote control device 30 (that is, FIGS. 4 to 7). Is written in the memory of the communication device so that the communication device can be used as the remote control device 30 easily. become.
(Modification of monitoring device)
On the other hand, in the monitoring device 10, the detection history obtained by the human sensor 18 and the displacement sensor 22 when in the alert state may be automatically displayed on the display panel 14.

  In the above embodiment, the power supply unit 28 of the monitoring device 10 has been described as receiving power from a battery and supplying power to the internal circuit, like the power supply unit 48 of the remote control device 30. Since it is installed indoors, it may be operated by receiving power supply from an external power source such as a commercial power source or an AC adapter.

  In addition, the power supply unit 28 can use both an external power supply and a built-in battery. When power is supplied from the external power supply, the power supply is supplied to the internal circuit using the external power supply. When there is no supply, power may be supplied to the internal circuit using a battery.

  Also in this case, as in the above embodiment, if the power supply voltage (sensor voltage) of the monitoring device 10 is transmitted to the remote control device 30, a decrease in the remaining battery level of the monitoring device 10 is detected on the remote control device 30 side. Thus, the user can be notified.

  In addition, when a search command for the remote control device 30 is input by operating the operation switch 12 in the monitoring device 10, a search signal is transmitted from the monitoring device 10 to the previously registered remote control device 30, and the search signal is received. On the remote control device 30 side, a predetermined search sound may be generated from the speaker 34 for a predetermined time.

In this way, when the location of the remote control device 30 becomes unknown in the room, the remote control device 30 can be easily found.
Further, when the monitoring device 10 is in the alert release state, the monitoring device 10 and the remote control device 30 periodically perform location confirmation communication, and when the communication is interrupted, the monitoring device 10 side The control unit 20 may determine that the remote control device 30 has gone out of the communicable area (that is, the user has gone out) and automatically shift to the alert state.

  Further, in this case, when communication between the monitoring device 10 and the remote control device 30 is resumed, the control unit 20 on the monitoring device 10 side determines that the user has returned home, cancels the warning state, and The monitoring result (detection history) may be transmitted to the remote control device 30, and the control unit 40 may notify the user of the monitoring result (detection history) on the remote control device 30 side.

  In addition, when the monitoring device 10 is in a warning state and a detection signal is output from the human sensor 18 or the displacement sensor 22, the control unit 20 activates the alarm device so that light, flash, sound, sound, etc. May be used to threaten suspicious persons.

  In addition, when the monitoring device 10 receives the warning cancellation signal transmitted from the remote control device 30, the control unit 20 may generate a sound such as “I will come home soon” to an audio device in the room. In this way, when there is an intruder in the room, it is possible to prevent the intruder and the user from matching each other by leaving the intruder.

  Further, when the monitoring device 10 is in a warning state and a detection signal is output from the human sensor 18 or the displacement sensor 22, detection information corresponding to the detection signal is sent to a preset telephone terminal or information terminal. You may make it notify. For this notification, sound, voice, or mail may be used.

  In addition, as one of the operating states, the monitoring device 10 notifies the remote control device 30 when a person is not detected by the human sensor 18 for a certain period of time, separately from the warning state and the warning release state. The monitoring target person detection state may be set.

In this way, for example, it is possible to detect that an elderly person or a child as a monitoring target has gone out of the room and notify the remote control device 30 to that effect. Can be secured.
(Modification of security system)
Next, in the above-described embodiment, it has been described that there is one monitoring device 10, but, for example, a plurality of monitoring devices 10 are distributed in a building, and a network is constructed by the plurality of monitoring devices 10. You may do it.

In this case, it is preferable that the monitoring devices 10 operate as in the following a) to e) by communicating via a network.
a) Priorities are assigned to a plurality of monitoring devices 10, and the main monitoring device 10 having the highest priority order periodically communicates with other monitoring devices 10 to confirm the location.

b) The detection history of each monitoring device 10 is collected from the other monitoring devices 10 by the main monitoring device 10 and distributed to all the monitoring devices 10 so that the information is shared by all the monitoring devices 10.
