Description

  The present invention relates to an improvement in a wireless alarm system that transmits a control signal to each other and outputs an alarm in conjunction with a plurality of alarm devices when any alarm device detects an abnormality to be monitored.

  In the wireless alarm system as described above, in order to identify the alarm device belonging to the system, the identification information assigned to each alarm device is registered in another alarm device as the identification information registration mode. . For example, in a system consisting of a parent alarm device that controls the interlocking operation of the system and a child alarm device controlled by the parent alarm device, after performing a predetermined registration operation on the parent alarm device to enter the registration mode, By performing registration operation on each alarm device, a registration request signal including identification information of the child alarm device is transmitted from the child alarm device to the parent alarm device, and the parent alarm device is identified from the parent alarm device to the child alarm device. The identification information is registered in the parent alarm device and the child alarm device by the procedure of transmitting the response signal including the information.

In Patent Document 1 below, in a meter reading terminal system including a slave unit connected to a sensor and a master unit that collects meter reading data of the slave unit, the master unit is transmitted as a transmission signal from the slave unit by a predetermined operation. When the slave unit presses the registration button, the slave unit adds identification information to the registration request command and sends it to the master unit. The master unit sends the registration request command to the registration request command. Register the added identification information, add the identification information of the parent device, and reply to the registration request. The slave device registers the returned identification information of the parent device, and further confirms the end of registration. A method for registering identification information to be transmitted to a machine is disclosed.

  However, in the wireless alarm system as described above, it is necessary to perform a registration operation in each of the parent alarm device and the child alarm device in the registration mode. Accordingly, the present invention provides a wireless alarm system having a novel configuration in which a registration mode is automatically executed after power is turned on.

  The wireless alarm system according to the present invention transmits a control signal to each other, and when any alarm device detects an abnormality to be monitored, the alarm system is linked with a plurality of alarm devices to output an alarm. Identification information for identifying alarm devices belonging to the same system is assigned to the parent alarm device and the child alarm device. A storage unit for registering identification information of the child alarm device, and upon receiving a predetermined operation, starts a registration mode, receives a registration request signal transmitted by the child alarm device, and is included in the registration request signal A control unit that registers the identification information of the child alarm device in the storage unit, and the child alarm device receives a power-on operation and a storage unit for registering the identification information of the parent alarm device When, Transmits the serial registration request signal, and a control unit for registering the identification information of the parent alarm device included in the registration notification signal sent back from the master alarm device in the storage unit.

  The parent alarm device may be configured to automatically end the registration mode when a predetermined time has elapsed since the registration mode was started.

  Alternatively, the parent alarm device may be configured to automatically end the registration mode when a predetermined time elapses without receiving the registration request signal after starting the registration mode.

  The parent alarm device may notify the number of child alarm devices whose identification information is registered in the storage unit of the parent alarm device when the registration mode ends.

  According to the present invention, when a predetermined operation and power-on operation (battery attachment) are performed on the parent alarm device, the registration mode is started. Thereafter, when a power-on operation is performed on the child alarm device, the parent alarm device receives a child alarm. Since the identification information of the alarm device is automatically registered and the identification information of the parent alarm device is automatically registered in the child alarm device, it does not take time. Here, the child alarm device is powered on after a predetermined operation is completed on the parent alarm device.

  In a configuration in which the parent alarm device automatically ends the registration mode when a predetermined time has elapsed after starting the registration mode or when the predetermined time has elapsed without receiving a registration request signal, There is no need to perform any special operations to end the mode.

  In addition, when the alarm device is configured to notify the number of child alarm devices whose identification information has already been registered when the registration mode ends, if there is a child alarm device that has failed to register, it can be simplified. Therefore, it is possible to take appropriate measures such as moving away the radio noise source.

  The present invention is suitable for an alarm system that transmits a control signal to each other and outputs an alarm in conjunction with a plurality of alarm devices when any alarm device detects an abnormality to be monitored. Examples of such an alarm system include other alarm systems such as a residential fire alarm system, a gas leak alarm system, and a crime prevention alarm system. Hereinafter, the fire alarm system will be described as an example.

FIG. 1 is a block diagram showing a schematic configuration of an alarm device to which the present invention is applied, and FIG. 2 is a perspective view showing an appearance of the alarm device.
The alarm device 1 includes, for example, a detection unit 11 that detects heat or smoke due to fire as a monitoring target, an operation unit 12 that receives an alarm stop operation, an audio output unit 13 that outputs an alarm sound, and an antenna 18. A communication unit 14 that transmits and receives control signals to and from other alarm devices 1, a storage unit 16 that stores identification information assigned to the alarm device 1, and a control unit 17 that controls these units. I have. Reference numeral 11 a denotes a protective cover for protecting the detection unit 11, 12 a denotes a push button provided on the operation unit 12, and 13 a denotes a sound passage hole for a speaker constituting the audio output unit 13.

  FIG. 3 is a block diagram of an alarm system according to the present invention. The alarm device 1 includes a parent alarm device 1 # 1 and child alarm devices 1 # 2 to 1 # 5. The basic configuration of the parent alarm device 1 # 1 and the child alarm devices 1 # 2 to 1 # 5 is almost the same, but there are differences in the control program executed by the control unit 17, the storage capacity of the storage unit 16, and the like. . Moreover, transmission of the control signal by radio is always performed between the parent alarm device 1 # 1 and the child alarm devices 1 # 2 to 1 # 5, and the child alarm devices 1 # 2 to 1 # 5 are Does not transmit control signals. Each alarm device 1 is assigned with unique identification information in advance, and the parent alarm device 1 # 1 has its own identification information and all the identification information of the child alarm devices 1 # 2 to 1 # 5. Is registered in the storage unit 16. On the other hand, the child alarm devices 1 # 2 to 1 # 5 register their own identification information and the identification information of the parent alarm device 1 # 1 in the storage unit 16. These pieces of identification information are used to identify the alarm device 1 belonging to the system and to specify the transmission source and the transmission destination in the transmission of the control signal.

  The transmission of the control signal is performed according to, for example, a low power security system standard. In this standard, a radio station is composed of a master unit and a slave unit, and selects one of the channels in which the 400 MHz band is divided into 48 channels so that the master unit and the slave unit transmit signals to each other. Yes. In the present invention, it is assumed that the same channel is preselected in all alarm devices 1.

  The basic operation by the alarm device 1 is performed as follows. That is, when the child alarm devices 1 # 2 to 1 # 5 detect an abnormality to be monitored, the child alarm devices 1 # 2 to 1 # 5 output an alarm and transmit an interlock request signal to the parent alarm device 1 # 1. When the master alarm device 1 # 1 receives the interlock request signal, the master alarm device 1 # 1 outputs the interlock command signal to the other child alarm devices 1 # 2 to 1 # 5 while outputting the alarm in conjunction with the alarm signal. When the parent alarm device 1 # 1 detects an abnormality to be monitored by itself, the parent alarm device 1 # 1 outputs an alarm and transmits an interlock command signal to all the child alarm devices 1 # 2 to 1 # 5. Then, the child alarm devices 1 # 2 to 1 # 5, when receiving the interlock command signal transmitted from the parent alarm device 1 # 1, outputs the alarm in conjunction with each other.

  And if alarm stop operation is received by child alarm device 1 # 2-1 # 5 while outputting an alarm, child alarm device 1 # 2-1 # 5 will be sent to parent alarm device 1 # 1. Send an alarm stop request signal. When the parent alarm device 1 # 1 receives the alarm stop request signal, the parent alarm device 1 # 1 stops the alarm for a predetermined time and transmits an alarm stop command signal to the other child alarm devices 1 # 2 to 1 # 5. Further, when the parent alarm device 1 # 1 accepts the alarm stop operation, the parent alarm device 1 # 1 stops the alarm for a predetermined time and transmits an alarm stop command signal to all the child alarm devices 1 # 2 to 1 # 5. The child alarm devices 1 # 2 to 1 # 5 stop the alarm for a predetermined time when receiving the alarm stop command signal transmitted by the parent alarm device 1 # 1.

  As described above, the transmission of the control signal between alarm devices includes alarm device identification information in order to specify the transmission source and the transmission destination. In order to realize this, the identification information of all the child alarm devices 1 # 2 to 1 # 5 belonging to the alarm system is registered in the parent alarm device 1 # 1, and the child alarm devices 1 # 2 to 1 # 5 are registered. Needs to execute in advance a registration mode for registering the identification information of the parent alarm device 1 # 1, but the present invention is characterized in that the registration mode is efficiently performed.

  That is, in the present invention, when the parent alarm device 1 # 1 receives a predetermined operation (for example, pressing of a registration button) or a power-on operation (including battery installation), the child alarm devices 1 # 2 to 1 # 5 Upon receiving the transmitted registration request signal, a registration mode for registering the identification information of the child alarm devices 1 # 2 to 1 # 5 included in the registration request signal in the storage unit 16 is started. In contrast, when the child alarm devices 1 # 2 to 1 # 5 accept the power-on operation, the child alarm devices 1 # 2 to 1 # 5 transmit a registration request signal and are included in the registration notification signal returned from the parent alarm device 1 # 1. The identification information of the parent alarm device 1 # 1 is registered in the storage unit 16. In such a configuration, the registration mode is automatically executed only by turning on the power or mounting the battery in order to start the operation of the alarm device 1, so that it does not take time and effort. In addition, when a power-on operation is performed on the child alarm devices 1 # 2 to 1 # 5, a registration request signal is transmitted to the parent alarm device 1 # 1 from the child alarm devices 1 # 2 to 1 # 5 side. If the devices 1 # 2 to 1 # 5 are sequentially turned on, the registration request signals are unlikely to be transmitted simultaneously from the plurality of child alarm devices 1 # 2 to 1 # 5. The registration of identification information fails due to collision of request signals.

  Further, the parent alarm device 1 # 1 may be configured to automatically end the registration mode when a predetermined time (for example, 8 minutes) has elapsed since the registration mode was started. Alternatively, the registration mode may be automatically terminated when a predetermined time (for example, 2 minutes) elapses without receiving the registration request signal after starting the registration mode. In this case, the parent alarm device 1 # 1 starts a timer when a power-on operation is received or each time a registration request signal is received, and ends the registration mode when a time-out occurs. In these configurations, even if no special operation is performed to end the registration mode, the registration mode is automatically ended, so that further labor is not required.

  Furthermore, the parent alarm device 1 # 1 causes the audio output unit 13 to notify the number of child alarm devices 1 # 2 to 1 # 5 whose identification information has been registered in the storage unit 16 when the registration mode ends. It is good also as a structure. As a result, if there is a child alarm device 1 # 2 to 1 # 5 that has failed to be registered, it can be easily known. Appropriate measures can be taken, such as moving the source away.

  FIG. 4 is a flowchart showing signal transmission between the parent alarm device 1 # 1 and the child alarm devices 1 # 2 to 1 # 4 in the registration mode in time series.

In the registration mode of the flowchart, the parent alarm device 1 # 1 accepts a power-on operation at time T1.
Child alarm device 1 # 2 receives a power-on operation at time T2, and transmits a registration request signal to parent alarm device 1 # 1 at time T3.

  Since the registration command signal includes the identification information of the child alarm device 1 # 2, the parent alarm device 1 # 1 that has received the registration request signal registers the identification information and measures the predetermined time. Start the timer. At time T4, a registration notification signal is transmitted to the child alarm device 1 # 2.

  Since the registration notification signal includes identification information of the parent alarm device 1 # 1 and registration information indicating registration states of the child alarm devices 1 # 2 to 1 # 4, the child alarm device 1 # 2 If the registration of the own device is successful, the identification information of the parent alarm device 1 # 1 is registered, and a response signal is transmitted to the parent alarm device 1 # 1 at time T5. On the other hand, if the registration of the own device has failed, a registration request signal is transmitted again to the parent alarm device 1 # 1.

  Similarly, the child alarm device 1 # 3 receives a power-on operation at time T7 and transmits a registration request signal to the parent alarm device 1 # 1 at time T3. Receiving this registration request signal, the parent alarm device 1 # 1 registers the identification information of the child alarm device 1 # 3 and starts a timer. At time T8, a registration notification signal is transmitted to the child alarm device 1 # 3. The child alarm device 1 # 3 that has received the registration notification signal registers the identification information of the parent alarm device 1 # 1, and transmits a response signal to the parent alarm device 1 # 1 at time T9.

  The child alarm device 1 # 4 receives a power-on operation at time T10 and transmits a registration request signal to the parent alarm device 1 # 1 at time T11. Receiving this registration request signal, the parent alarm device 1 # 1 registers the identification information of the child alarm device 1 # 4 and starts a timer. At time T12, a registration notification signal is transmitted to the child alarm device 1 # 4. Receiving the registration notification signal, the child alarm device 1 # 4 registers the identification information of the parent alarm device 1 # 1, and transmits a response signal to the parent alarm device 1 # 1 at time T13.

  At time T14, because the timer activated by parent alarm device 1 # 1 at time T11 has timed up, parent alarm device 1 # 1 ends the registration mode. At this time, the parent alarm device 1 # 1 notifies the number of child alarm devices 1 # 1 to 1 # 4 whose identification information has been registered. The parent alarm device 1 # 1 may automatically end the registration mode when a predetermined number (maximum) of child alarm devices 1 # 2 to 1 # 4 have been registered.

  If the child alarm devices 1 # 2 to 1 # 4 do not receive the registration notification signal transmitted by the parent alarm device 1 # 1 before the predetermined time elapses after the registration request signal is sent back, If it is set as the structure which notifies the failure of registration from the output part 13, since the child alarm device 1 # 2-1 # 4 which registration failed can be identified immediately, it can respond quickly.

It is the block diagram which showed schematic structure of the alarm device to which this invention is applied. It is the perspective view which showed the external appearance of the alarm device to which this invention is applied. It is a block diagram of the alarm system by this invention. It is the flowchart which showed the signal transmission in a registration mode.
