Description

  The present invention provides a wireless crime prevention system including a wireless crime prevention sensor that outputs a ringing sound when an abnormality is sensed and transmits a detection signal thereof, and a wireless crime prevention receiver that receives a monitoring signal from the sensor and performs a predetermined processing operation. Regarding improvements.

  Recently, wireless security systems have become widespread in buildings that occupy a certain range such as residences, offices, apartment buildings, and buildings, and wireless security sensors that output sound and output detection signals when abnormalities are detected. And a wireless security receiver that receives a monitoring signal from the sensor and performs a predetermined processing operation.

  This wireless security sensor is divided into certain monitoring areas and installed, and each wireless security sensor has alarm sound switching means for switching what kind of sound is output when an abnormality is detected. The wireless security receiver also includes means for setting what processing should be performed when receiving a sensing signal from the sensor.

  That is, the wireless security sensor can be switched between alarm sound, notification sound, and silence (a state in which no sound is output), and the wireless security receiver can be set in any one of a warning mode, a notification mode and a non-warning mode. When the wireless security sensor detects an abnormality, it outputs an alarm sound that is switched at that time (nothing is output when silence is set).

On the other hand, the wireless security receiver can set a warning mode, a notification mode, and a non-warning mode that stipulate what kind of processing is performed when a sensing signal is received. When a sensing signal is received from either of them, an alarm sound (notification sound in the notification mode) is output and a monitoring area to which the sensor belongs is displayed. Then, a notification that a failure has occurred is notified to a preset report destination. In the non-warning mode, no processing is performed.

  By the way, as described above, in the conventional wireless security system, since the switching of the ringing sound on the wireless security sensor side and the mode setting on the wireless security receiver side are separately performed, these setting operations are troublesome. Met.

  For example, when you are away, it is necessary to switch so that alarm sounds or notification sounds are output from all sensors, and the receiver side must be set separately from the warning mode or notification mode. It is troublesome.

  The present invention is proposed in view of such circumstances, and automatically selects the type of ringing sound to be output on the wireless security sensor side in conjunction with the mode setting operation on the wireless security receiver side. An object is to provide a wireless crime prevention system that can be switched to.

In order to achieve the above object, in Claim 1 of the present invention, the wireless security receiver sets a mode in which a processing operation to be executed when a sensing signal is received from any one of the wireless security sensors is changed. Mode setting means,
Independent of the mode setting means, a sensor ringing sound changeover switch for switching the ringing sound of the wireless security sensor,
When any mode is set by the mode setting means and when at least one of the sensor ringing sound changeover switch is operated , a ringing sound switching signal is transmitted to the wireless security sensor. The wireless security sensor includes a sounding sound switching means for switching a sounding sound to be output at the time of sensing when receiving a sounding sound switching signal from the wireless security receiver. Here, with this sensor ringing sound changeover switch, the ringing sound of the sensor can be switched independently of the mode setting operation.

  Here, a ringing sound corresponding to the mode set by the receiver is defined in the ringing sound switching command signal, and the wireless security sensor that has received this command signal sets the defined ringing sound. Then, when an abnormality is detected, the receiver executes the set mode, while the sensor outputs a ringing sound corresponding to the mode.

  According to a second aspect of the present invention, the modes set by the mode setting means include at least a warning mode and a non-warning mode.

  The wireless security sensor returns a response signal to the wireless security receiver when receiving the ringing sound switching signal from the wireless security receiver.

According to a fourth aspect of the present invention , the ringing sound switching means includes ringing sound manual switching means for invalidating the input of the ringing sound switching signal from the wireless security receiver and switching the ringing sound to be output at the time of sensing. It is characterized by that.

  Here, according to the ringing sound manual switching means, the ringing sound can be switched independently on the sensor side by manual operation. Therefore, only a specific sensor can switch the ringing sound independently from the receiver, and a security system suitable for each user can be constructed.

In claim 5 , the wireless security receiver further comprises a remote controller for sending a warning temporary release signal to the wireless security receiver, the wireless security receiver executes the non-warning mode for a predetermined time when receiving the warning temporary release signal, and then Automatically return to the previous operating mode.

According to the first aspect of the present invention, in the first aspect of the present invention, when the mode is set by the wireless security receiver, the ringing sound switching signal is sent from the ringing sound switching command means to the wireless security sensor, Since the wireless security sensor switches the ringing sound to be output at the time of detection, the ringing sound setting of the sensor is switched in conjunction with the mode setting operation at the receiver, improving usability. Also, when the sensor ringing sound selector switch is operated, the ringing sound switching signal is sent from the ringing sound switching command means to the wireless security sensor, so that it is independent of the mode setting operation at the receiver. The sound of the sensor can be switched. Further, it is convenient because the ringing sound of the sensor can be switched by an operation at one place on the receiver side.

  In the second aspect, since the modes set by the mode setting means include at least a warning mode and a non-warning mode, the sound of the sensor can be switched at least by a setting operation of these modes. it can.

  In claim 3, when the wireless security sensor receives the ringing sound switching signal from the wireless security receiver, the wireless security sensor returns a response signal to the wireless security receiver, so that the receiver reliably transmits the ringing sound cutoff switching signal. It is possible to determine that the sound has been completed, and to reliably switch the ringing sound.

According to claim 4 , each wireless security sensor has a sounding sound manual switching means for invalidating the input of the sounding sound switching signal from the wireless security receiver and switching the sounding sound to be output at the time of sensing. The ringing sound can be switched independently on the sensor side. Therefore, only a specific sensor can switch the ringing sound independently from the receiver, and a security system suitable for each user can be constructed.

In claim 5 , the wireless security receiver executes the non-warning mode for a predetermined time when receiving the temporary warning release signal from the remote controller, and then automatically returns to the previous operation mode. In such a case, the alarm can be released by operating the remote controller without operating the sensor or the receiver one by one, which is convenient.

  Embodiments of the present invention will be described below.

  FIG. 1 is a diagram showing an example of a schematic configuration of a wireless crime prevention system according to the present invention. In this system, a wireless security receiver 1 installed at an appropriate location and a plurality of wireless security sensors 2 grouped for each monitoring area are combined. Here, as a method of grouping the sensors 2, a table in which the identification information of the sensor 2 and the corresponding monitoring area are registered may be provided in the receiver 1, and the frequency of the detection signal described later may be different for each group. It may be.

  When the wireless security sensor 2 in each monitoring area senses an abnormality, it transmits a sensing signal wirelessly and transmits it to the wireless security receiver 1. At that time, the wireless security sensor 2 that has detected the abnormality outputs the ringing sound set at that time. Note that the ringing sound to be output is any one of an alarm sound, a notification sound, and silence, and is switched and set by a process described later.

  The wireless security receiver 1 operates the mode setting switches B1 to Bn provided corresponding to each monitoring area, and can perform setting operation of a warning mode, a notification mode, and a non-warning mode for each monitoring area. When a detection signal is received from the wireless security sensor 2 during the execution of the mode or the notification mode, the display window W provided for each monitoring area is turned on or blinks, and an alarm sound (notification sound in the notification mode) ) Is output from the speaker SP, and notifications are made to the pre-registered report destinations P and Q through the networks N and N ′.

  Further, in the non-warning mode, even if a sensing signal is received from the wireless security sensor 2, the reception is not accepted.

  The remote controller 3 is used for a temporary alert release process described later, and is operated by a user to wirelessly transmit a temporary alert release signal, and the wireless security receiver 1 that receives this signal executes a non-alert mode described later. .

  In the present invention that performs such a basic operation, as described above, when the mode is set on the wireless security receiver 1 side, the ringing sound to be output by the wireless security sensor 2 is automatically set according to the mode. I am trying to switch.

  Therefore, each component is as shown below. That is, as shown in FIG. 2, the wireless security receiver 1 is composed of a microcomputer or the like, and a wireless signal such as a sensing signal between the signal processing unit 10 that controls the receiver 1 and the wireless security sensor 2. A wireless signal transmission / reception unit 11 for transmitting and receiving, a ringing sound output unit 12 for outputting a ringing sound according to a mode set by a process described later, and reporting that an abnormality has occurred in predetermined report destinations P and Q And an automatic notification unit 13 for performing the above operation.

  The signal processing unit 10 exhibits functions as external notification information setting means 10A, mode setting means 10B, discrimination control means 10C, ringing sound switching command means 10D, and notification control means 10E by software processing. The signal processing unit 10 may be configured by a dedicated LSI that exhibits an equivalent function.

  The external notification information setting means 10A is provided for setting information on whether or not to perform external notification for each monitoring area. In other words, in the alarm mode or the notification mode, when a detection signal is received from the sensor 2 in a certain monitoring area, an external notification is made, while when a detection signal is received from the sensor 2 in other monitoring areas. Is set to not make external notifications.

  The mode setting means 10B is provided for setting the execution of each mode of warning, notification, and non-warning for each monitoring area. Then, a ringing sound (alarm sound, notification sound, silence) corresponding to the set mode is also set.

  When receiving the sensing signal from the sensor 2, the discrimination control means 10C determines the monitoring area to which the sensor 2 belongs based on the above-described table and frequency, and the mode corresponding to the area, the type of ringing sound, The presence / absence of an external report is determined, and processing according to the determination result is performed.

  When the mode setting unit 10B sets the mode of a certain monitoring area, the ringing sound switching command unit 10D determines the set mode and outputs a ringing sound switching signal that defines the ringing sound according to the mode. It performs the function of sending to the sensor 2 in the monitoring area.

  Further, the ringing sound switching command means 10D includes a sensor ringing sound changeover switch 14 for switching the ringing sound corresponding to each of the warning, notification, and non-warning modes that each sensor 2 should output when an abnormality is detected. When this switch 14 is operated, regardless of the mode setting by the mode setting means 10B, a ringing sound switching command signal defining a ringing sound corresponding to each mode is output to all the sensors 2, and each sensor 2 In, it is switched to the prescribed ringing sound.

  The report control unit 10E registers a report destination for each monitoring area, operates based on an operation command from the discrimination control unit 10C, and sends an external report to the registered report destination via the automatic report unit 13. Eggplant.

  As shown in FIG. 3, one wireless security sensor 2 is configured by a microcomputer or the like, and a wireless signal such as a sensing signal is transmitted and received between the signal processing unit 20 that controls the sensor 2 and the wireless security receiver 1. A wireless transmission / reception unit 21, a sensor circuit 22 having a security sensor, and a ringing sound output unit 23 that outputs a ringing sound set by command from the wireless security receiver 1, as will be described later.

  The signal processing unit 20 includes a ringing sound switching unit 20A that switches ringing sounds based on a command from the wireless security receiver 1. The ringing sound switching unit 20A includes a ringing sound switching command invalidation switch 24 and a ringing sound. And a sound changeover switch 25.

  In the ringing sound output unit 23, an alarm sound, a notification sound, and silence are set as sounds to be output when the sensor 2 senses an abnormality. The sensor 2 receives the ringing sound switching command signal from the receiver 1. When this is done, the function of the signal processing unit 20 switches and sets the ringing sound of the type specified by the command signal in the ringing sound output unit 23.

  The ringing sound switching means 20 </ b> A can invalidate reception of the command signal from the receiver 1 by operating the ringing sound switching command invalidation switch 24. At that time, even if the command signal is received, it is invalidated, and switching of the ringing sound is determined only by operating the ringing sound changeover switch 25. That is, the ringing sound switching command invalidation switch 24 and the ringing sound switching switch 25 constitute ringing sound manual switching means.

  Here, the ringing sound switching invalidation switch 24 and the ringing sound switching switch 25 are provided independently, and the operation of the ringing sound switching switch 25 is accepted on condition that the switch 24 is valid. The present invention is not limited to this example, and one switch having both functions of the ringing sound switching invalidation switch 24 and the ringing sound switching switch 25 may be provided.

  For example, one slide switch is provided, and the position where the command signal is validated, the position where the alarm sound is switched as the ringing sound, the position where the notification sound is switched as the ringing sound, and the position where silence is switched as the ringing sound are defined. In addition, the ringing sound switching means 20A may determine the position.

  Next, a specific operation of the wireless crime prevention system having such a configuration will be described. FIG. 4 is a time chart showing an operation when the mode of the specific monitoring area is set to the warning mode in the receiver 1.

  That is, in FIG. 4A, a ringing sound switching command signal is sequentially sent from the receiver 1 to all the sensors 2 in one monitoring area. Moreover, in FIG.4 (b), the command signal is simultaneously transmitted to all the sensors 2 which belong to each of the monitoring areas G1, G5, and Gn. Furthermore, in FIG.4 (c), it transmits simultaneously with respect to all the sensors 2 which belong to all the monitoring areas.

  When transmitting by monitoring area and sensor, the command signal is added with a monitoring area code or sensor code, and each sensor determines that it is specified based on the monitoring area code or sensor code. To do.

  In any case, each sensor 2 sets the type of ringing sound to be output at the time of sensing based on the received ringing sound switching command signal. In this case, since the receiver 1 is set in the warning mode, the warning mode is set. Set the corresponding alarm sound. Note that notification sound is set in the notification mode, and silence is set in the non-warning mode.

  5 and 6, each sensor 2 returns a response signal when it receives a ringing sound switching command signal. In other words, when the receiver 1 is set in the alert mode, a ringing sound switching command signal is sequentially output to each sensor, but a response signal is returned for a predetermined time after the command signal is output to each sensor 2. If not, the command signal is sent to the sensor 2 again. Here, the response signal is returned not only when the receiver 1 is set to the alert mode, but also when the receiver 1 is set to the alert / non-alert mode.

  As shown in FIG. 5, the timing for retransmitting the command signal to the sensor 2 that has not returned a response signal for a predetermined time may be immediately after a predetermined time has elapsed without confirmation of the response. As shown in FIG. 6, it may be after the transmission of the command signal to all the sensors 2 is completed.

  FIG. 7 is a time chart showing an operation when a temporary alarm release signal is sent to the wireless security receiver 1 by operating the remote controller 3.

  That is, when a warning temporary cancellation signal is sent from the remote controller 3 to the receiver 1, the receiver 1 is switched from the warning or notification mode to the non-warning mode. At that time, a ringing sound switching command signal is transmitted from the receiver 1 to all the sensors 2 by the notification sound switching command means 10D, and all the sensors 2 set the type of the notification sound to “silence”.

  Then, the receiver 1 waits for the elapse of the predetermined time T in that state, and when it has elapsed, the receiver automatically returns to the previous operation mode, that is, the alert mode or the notification mode.

  Then, a ringing sound switching command signal is sent from the receiver 1 to all the sensors 2 by the ringing sound switching command means 10D, and all the sensors 2 are set to the type of the previous notification sound.

  Note that. In FIG. 7, an alarm sound is illustrated as a ringing sound from the sensor 2, but if the warning temporary release signal is in the notification mode before being sent from the remote controller 3, the ringing sound from the sensor 2 in that case is This is a notification sound.
