  However, in the radio system having the communication state monitoring function as described above, when the radio system is stopped for battery replacement of the radio, etc., the radio set belonging to the radio system is reset. I had to. In other words, identification information (ID) of a communication destination wireless device is registered in the wireless device, and when one wireless device is stopped for battery replacement or the like, It was necessary to delete the registered ID by operating a dip switch or the like for all the wireless devices. If this processing is not performed, a communication error message is notified because communication cannot be performed with the stopped wireless device during communication status monitoring (periodic radio wave check). Therefore, the present invention is a wireless that can simply prohibit the communication status monitoring function of the radio system and not notify the abnormality of the communication status by simply performing a predetermined operation on the radio that is desired to be separated from the radio system. The issue is to provide a machine system.

The radio system according to the present invention includes a plurality of radios that monitor security factors, and when any of the radios detects a security abnormality, an alarm interlocking function in which other radios interlock and alarm, It has a communication state monitoring function that monitors the communication state between the wireless devices in a cycle and notifies when a communication abnormality is detected, and the wireless device in the system includes an operation detection unit and a communication control unit, When the operation detection unit detects a predetermined operation, the communication control unit transmits a disconnection signal to another wireless device, and receives the signal from the other wireless device, so that The communication state monitoring function is prohibited , and the alarm interlocking function of the entire radio system is prohibited.

  The wireless device includes an attachment base portion fixed to an installation location and a main body portion detachably attached to the attachment base portion, and the communication control unit is configured such that the operation detection unit is connected to the main body unit. When the removal is detected, the separation signal may be transmitted.

In the wireless system of the present invention, when the operation detection unit detects a predetermined operation, the wireless device transmits a disconnection signal to another wireless device, thereby prohibiting the communication state monitoring function. Alternatively, the communication state monitoring function can be simply prohibited during an operation test or the like so that a communication abnormality is not notified.

In addition , since the alarm interlocking function is further prohibited by transmitting a separation signal, noise can be suppressed by removing the subject main body for testing during an operation test. That is, if the main body is removed and tested, even if the main body is alarmed by the test, the other radios do not alarm and do not report any communication abnormality, so that noise does not disturb the surroundings.

  In particular, in a configuration that sends a disconnection signal when the main body is removed from the mounting base, the communication status monitoring function is automatically prohibited during maintenance or operation tests, so it is convenient to avoid forgetting to operate. is there.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a radio constituting the radio system of the present invention, and FIG. 2 is a joint between a main body portion and a mounting base portion of the radio constituting the radio system of the present invention. FIG. 3 is an overall configuration diagram of a radio system according to the present invention.

  This radio system 1 monitors the communication state between the radio units 10 at a predetermined cycle, and an alarm interlocking function in which another radio unit interlocks and alarms when any of the radio units 10 detects a security abnormality. And a communication state monitoring function for notifying when a communication abnormality is detected. Security factors may include fire, gas leakage, toxic gas generation, suspicious person intrusion, etc., but are not particularly limited.

  The radio device 10 has a distinction between a master radio device 10A and a slave radio device 10B, but the basic configuration is almost the same, and both of them are a mounting base portion 12 fixed to an installation place such as a wall surface or a ceiling surface. And a main body part 11 that is detachably attached to the mounting base part 12. The main body part 11 includes a detection part 11a that monitors security factors and, for example, “P, P, fire. An alarm output unit 11b that outputs an alarm sound, an operation detection unit 11c that receives a user operation, a communication control unit 11d that wirelessly communicates with another wireless device 10, and a control unit 11e that controls these units. Yes.

  The storage unit 11f is a memory for storing the identification information of the child radio device 10B belonging to the radio device system 1 by the parent radio device 10A, and is configured by a nonvolatile rewritable memory.

  As shown in FIG. 2, on the upper surface (joint surface) of the main body 11 of the wireless device 10, a dip switch 11h for setting identification information, a damper switch 11g for detecting removal from the mounting base, and An engagement portion 11 i that engages with an engagement claw of the mounting base portion 12 is provided. On the other hand, the lower surface (joint surface) of the mounting base portion 12 is provided with an engagement claw 12a and a screw hole 12b through which a screw for fixing to the installation surface is inserted. The damper switch 11g detects the removal from the mounting base portion 12 depending on whether or not the central protrusion is pressed by the mounting base portion 12.

  In the wireless device system 1, basically, the parent wireless device 10A and the child wireless device 10B communicate with each other by wireless communication so that alarms are interlocked. Note that such a communication mode has an advantage that the range in which wireless communication can be performed becomes wider by distributing the child wireless devices 10B around the parent wireless device 10A.

  The mechanism of the alarm linkage function is as follows. That is, when any of the slave radio devices 10B detects an abnormality, the slave radio device 10B warns and transmits an interlock request signal to the master radio device 10A. The master radio device 10A that has received the interlock request signal issues an alarm in conjunction with it, and transmits an interlock command signal to the other slave radio device 10B to cause an alarm in conjunction. Further, when the master radio device 10A detects an abnormality, the master radio device 10A issues an alarm and transmits an interlock command signal to all the slave radio devices 10B to cause the alarm in conjunction.

  The same applies to the alarm stop operation. That is, when any slave radio device 10B receives an alarm stop operation, the slave radio device 10B stops the alarm and transmits an alarm stop request signal to the master radio device 10A. The master radio device 10A that has received the alarm stop request signal stops the alarm and transmits an alarm stop command signal to the other slave radio device 10B to stop the alarm. When the master radio device 10A accepts an alarm stop operation, the master radio device 10A stops the alarm and transmits an alarm stop command signal to all the slave radio devices 10B to stop the alarm.

  In the communication status monitoring function, the parent radio device 10A sequentially transmits a call signal including the identification information of the child radio device B to all the child radio devices 10B in a predetermined cycle, and corresponds to the identification information. The communication state is monitored by determining whether or not there is a response signal from the slave radio device 10B. Here, if even one of the slave radio units 10B does not return a response signal, the master radio unit 10A determines that the communication is abnormal, and a communication error is generated by a message such as “A communication error has occurred”, for example. And a notification command signal is transmitted to all the slave radio devices 10B to notify the same.

  However, when the communication state monitoring as described above is constantly performed, for example, if maintenance of battery replacement is performed in the slave radio device 10B, the slave radio device 10B cannot return a response signal during the maintenance. Is regarded as a communication error. As a result, a communication abnormality is notified from all the radio devices 10, and there is a problem that it is very troublesome.

  Therefore, according to the present invention, when the operation detection unit 11c detects a predetermined operation in the slave radio device 10B, the communication control unit 11d adds identification information to the other radio device 10, that is, the parent radio device 10A. The communication state monitoring function is prohibited by transmitting a leave signal. When receiving the leave signal, the master radio device 10A identifies the transmission source child radio device 10B from the identification information, registers that the child radio device 10B has left the radio system 1 in the storage unit 11f, and communicates The monitoring function is automatically disabled. Note that the communication state monitoring function of the entire wireless device system 1 may be prohibited, or the child wireless device 10B that is the transmission source of the leaving signal may be specified, and only the child wireless device 10B may be excluded from the communication state monitoring target.

  When the slave radio device 10B detects an operation for returning to the radio device system 1, the communication control unit 11d transmits a return signal with identification information added to the master radio device 10A. Receiving the signal, the parent radio device 10A identifies the transmission source child radio device 10B from the identification information, and updates the storage unit 11f assuming that the child radio device 10B has returned to the radio device system 1. If all the slave radio devices 10B have returned to the radio device system 1, the communication state monitoring function is permitted. In this way, it is possible to prohibit the communication state monitoring function from being notified by a simple operation during maintenance or an operation test so as not to notify the communication abnormality, and to restore the original state.

  If only the communication state monitoring function in the radio system 1 is prohibited by the disconnection signal and the alarm interlocking function is not prohibited, for example, the main body part 11 removed from the attachment base part 12 is attached after battery replacement. Even if it is forgotten to return to the base part 12, it can be communicated only with the main body part 11, and it is safer because an interlocking alarm is given in the event of a fire.

  As the predetermined operation, for example, an operation of a maintenance button is conceivable. As another aspect, a damper switch 11g for detecting the removal of the main body 11 is provided in the operation detection unit 11c, and the main body 11 is detached from the mounting base 12. When this happens, a departure signal may be transmitted. In a configuration in which the main body 11 can be detached from the mounting base portion 12, the detection portion 11a, a battery, and the like are generally built in the main body portion 11 side. For this reason, the main body portion 11 is removed from the mounting base portion 12 during maintenance. It will be. Therefore, when the main body 11 is detached from the mounting base 12, the separation signal is automatically transmitted at the time of maintenance, so that the separation signal is automatically transmitted without maintenance. You can leave.

  Moreover, it is good also as a structure which prohibits not only a communication state monitoring function but an alarm interlocking | linkage function with a leaving signal. In this way, if the main body 11 to be tested is removed from the mounting base portion 12 during the operation test and the test is performed, even if the radio device 10 gives an alarm by the test, the other radio devices 10 will be alarmed in conjunction with each other. In addition, since no communication abnormality is reported, the surroundings are not disturbed by noise.

  FIG. 4 is a time chart for explaining an example of the basic operation of the radio apparatus system of the present invention. In this example, the communication state monitoring function is prohibited by the leave signal transmitted from the slave radio device 10B, but the alarm interlocking function is not prohibited.

  According to this time chart, the master radio device 10A monitors the communication state at a predetermined cycle, but the main body portion 11 of the slave radio device 10B is removed from the attachment base portion 12, and the slave radio device 10B transmits a disconnection signal. Then, during the period from when it is attached again to when the return signal is transmitted, monitoring of the communication state is prohibited. However, during the period, the master radio device 10A transmits an interlock command signal to cause an alarm in conjunction with another slave radio device 10B, and then transmits an alarm stop command signal to thereby transmit another slave radio device. The machine alarm is stopped.

  FIG. 5 is a time chart for explaining another example of the basic operation of the radio system of the present invention. In this example, the communication state monitoring function and the alarm interlocking function are prohibited by the leave signal transmitted by the slave radio device 10B.

  According to this time chart, the master radio device 10A monitors the communication state at a predetermined cycle, but the main body portion 11 of the slave radio device 10B is removed from the attachment base portion 12, and the slave radio device 10B transmits a disconnection signal. After that, the communication state monitoring function and the alarm interlocking function are prohibited during the period from when it is attached again to when the return signal is transmitted.
