  By the way, in the said conventional system, there existed a problem that operation switching of the operation mode of a crime prevention receiver was performed by the operation input part of a crime prevention receiver, and an operator had to approach the crime prevention receiver and was troublesome. On the other hand, when the operation mode of the security receiver is switched using a wireless transmitter, there are problems that the system cost increases and the wireless transmitter may be lost.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a security system capable of suppressing an increase in system cost and easily switching the operation mode of the security receiver.

  In order to achieve the above object, the invention of claim 1 includes one or more security sensors that are installed in a dwelling unit and detect an abnormality such as an intrusion of a suspicious person and output a detection signal when the abnormality is detected, and a security sensor A security receiver that has two operation modes, a warning mode for issuing an alarm when an output detection signal is received and a non-warning mode that does not issue an alarm even when a detection signal is received; One or more devices that are installed in a dwelling unit and whose operation state is switched by manual operation, one or more monitoring terminals that are assigned a unique address and monitor the operation state of the device, and a security receiver and monitoring by a signal line The signal transmission means connected to the terminal device for transmitting signals between the security receiver and the monitoring terminal device via the signal line, and the security receiver at the address in advance. Storage means for storing addresses of one or more specific monitoring terminals for which a corresponding relationship is determined and conditions relating to an operating state of a device monitored by the specific monitoring terminal, and the operating state in the storage means And a signal processing means for transmitting a warning setting command for setting the warning mode to the security receiver via the signal line from the signal transmission means when the condition relating to the stored operation state is matched. To do.

  According to the first aspect of the present invention, the operation mode of the security receiver can be switched to the warning mode by changing the operation state of a device (for example, an air conditioner) installed in the dwelling unit. There is no need to perform the switching operation at the operation input unit of the security receiver, so that the troublesome approach of the operator to the security receiver is eliminated, and there is no possibility of increasing the system cost such as using a wireless transmitter.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The crime prevention system according to the present embodiment is installed in a dwelling unit as shown in FIG. 1, detects an abnormality such as an intrusion of a suspicious person, and outputs a detection signal when the abnormality is detected, and outputs from the crime prevention sensor 2 Security receiver 1 having two operation modes: a warning mode for issuing an alarm when receiving a detected signal and a non-warning mode for not generating an alarm even if a detection signal is received, and a device installed in a dwelling unit (for example, An air conditioner) 3, a monitoring terminal 4 for monitoring the operating state of the device 3, and a control terminal 5 to which the security receiver 1 and the monitoring terminal 4 are connected via a signal line Ls. Here, a unique address is assigned to each of the security receiver 1, the monitoring terminal 4, and the control terminal 5, and the security receiver 1, the monitoring terminal 4, and the control terminal 5 identify each other by the addresses. Thus, transmission signals can be exchanged via the signal line Ls.

  The security sensor 2 detects, for example, a vibration that occurs when a window of a dwelling unit is opened or a window glass is broken, a sensor that detects the presence of a person in a detection area, or a door lock is unlocked. When these abnormalities are detected, a detection signal is output to the security receiver 1 via the connection line Lx. However, since such a security sensor 2 is conventionally well-known, detailed illustration and description of the configuration will be omitted.

  The security receiver 1 includes a signal transmission unit 10 that transmits a transmission signal via a signal line Ls, and a security sensor interface (I / F) unit 11 that takes in a detection signal output from the security sensor 2 via a connection line Lx. And a control unit 12 having a CPU as a main component, and an alarm generation unit 13 that is controlled by the control unit 12 and generates an alarm by sound or light. Here, as described above, the control unit 12 has the two operation modes of the warning mode and the non-warning mode, and when the detection signal is output from any one of the security sensors 2 when the warning mode is set, the control is performed. The unit 12 controls the alarm generation unit 13 to generate an alarm, thereby notifying the dweller of the dwelling unit of the occurrence of an abnormality (for example, breaking of the window glass).

  The monitoring terminal 4 includes a signal transmission unit 40 that transmits a transmission signal via the signal line Ls, and a device interface (I / F) unit that is connected to the device 3 via the connection line and detects the operating state of the device 3. 41 and a control unit that notifies the control terminal device 5 of a change in the operating state via the signal line Ls when the device I / F unit 41 detects that the operating state of the device 3 has changed. 42.

  On the other hand, the control terminal 5 includes a signal transmission unit 50 that transmits a transmission signal between the crime prevention receiver 1 and the monitoring terminal 4 via the signal line Ls, a storage unit 51 including a nonvolatile memory, and a CPU. And a signal processing unit 52 as a main component. In the storage unit 51, the unique address assigned to the security receiver 1 and the addresses of one or more specific monitoring terminals 4 for which a correspondence relationship is determined by the address between the security receiver 1 and The condition regarding the operation state of the device 3 monitored by the monitoring terminal 4 is stored. For example, the condition that the address of the monitoring terminal 4 is associated with the address of the security receiver 1 and the device 3 monitored by the monitoring terminal 4 is in the ON state is set and stored in the storage unit 51.

  FIG. 2 shows a format of a transmission signal, which is composed of a transmission destination address, a transmission source address, a packet type, and control contents. The packet type includes a control request for requesting the security receiver 1 to set the alert mode, and a control result returned from the security receiver 1 to the control request transmission source (control terminal 5) (the control content is ACK). And NAK), and a state change notification (control content is in an off state and an on state) for notifying that the operation state of the device 3 has changed from the monitoring terminal 4 having an address correspondence relationship, Is assigned.

  Next, the operation for setting the security receiver 1 to the alert mode will be described with reference to the sequence flow of FIG. Note that a remote control transmitter 6 is attached to the device (air conditioner) 3 exemplified in the present embodiment, and a resident usually operates the remote control transmitter 6 to turn the device 3 on and off.

  First, it is assumed that the device 3 is in an off state. However, such a situation is also stored in the storage unit 51 of the control terminal 5. At this time, when the remote control transmitter 6 is operated and the device 3 is turned on, the device I / F unit 41 detects a change in the operation state of the device 3 (change from the off state to the on state) in the monitoring terminal device 4. The control unit 42 transmits a state change notification transmission signal to the control terminal 5 in order to notify the control terminal 5 that the operation state of the device 3 has changed from the off state to the on state.

  In the control terminal 5, the signal processing unit 52 that has received the state change notification matches the condition that the device 3 is in the ON state in comparison with the condition stored in the storage unit 51. The unit 52 generates control data (warning setting command) with the packet type as the control request and the control content as ON control, and uses the address of the security receiver 1 stored in the storage unit 51 as the transmission destination address, and the own address The transmission signal including the generated control data (packet type and control content) is transmitted from the signal transmission unit 50 via the signal line Ls. Then, the security receiver 1 whose destination address matches its own address captures the transmission signal from the signal transmission unit 10 to the control unit 12, and the control unit 12 switches the operation mode to the alert mode based on the control data. Furthermore, the control unit 12 generates control data with the packet type as the control result and the control content as ACK (set in the alert mode), and uses the address of the control terminal 5 that is the transmission source of the control request as the transmission destination address. Then, the transmission signal including the generated control data (packet type and control content) is transmitted from the signal transmission unit 10 via the signal line Ls using the self address as the transmission source address.

  Thus, according to the present embodiment as described above, the operation mode of the security receiver 1 can be switched to the alert mode by changing the operation state of the device (for example, air conditioner) 3 installed in the dwelling unit. Therefore, the operation mode can be easily switched at a place away from the security receiver 1 (where the device 3 is installed).

  In the present embodiment, the signal processing unit 52 serving as a signal processing unit and the storage unit 51 serving as a storage unit are provided in the control terminal device 5, but these units may be provided in the monitoring terminal device 4.

  Here, the use of a device-embedded network technology called EMIT (Embedded Micro Internetworking Technology) (a network technology having a function capable of easily incorporating middleware into a device and connecting to the network, hereinafter referred to as EMIT technology). From various external devices (not shown) such as mobile phones, PCs (Personal Computers), PDAs (Personal Digital Assistants), and PHSs (Personal Handy phone Systems), various equipment (lighting devices, air conditioners, power units, sensors) , An electric lock, a web camera, etc., hereinafter referred to as an EMIT terminal.) By accessing <not shown>, the EMIT terminal can be remotely monitored and controlled.

  Note that the EMIT terminal is a built-in device equipped with a microcomputer, and is a device-embedded middleware for connecting to the network and is equipped with EMIT software that realizes the EMIT technology. For example, in this embodiment, EMIT software may be installed in the security receiver 1, the monitoring terminal 4, and the control terminal 5.
