Hereinafter, it is referred to as a “pendant type slave unit”, and the configuration and reference numerals of the cordless slave unit 2 in FIG. 1 are used.

  The pendant type handset 2 requests (for example, an alarm sound) that the user (elderly person) presses a button periodically (for example, once a day, at a set time).

  Note that the pendant type handset 2 enters the sleep mode when the CPU (central processing unit) (main control unit 11) is turned off when wireless communication with the cordless base unit 1 is unnecessary. The active mode is activated only when the alarm time or button is pressed.

  Switching between the sleep mode and the active mode is performed only by the pendant type handset 2, and the cordless base unit 1 is always energized and is always in the reception state (active mode). In other words, the pendant type slave unit 2 is in an active mode only when an event occurs, and the cordless master unit 1 constantly monitors so that the pendant type slave unit 2 does not miss it whenever the pendant type slave unit 2 starts communication. ing.

  The pendant type handset 2 determines that if the user presses the button within a specified time (for example, within 3 minutes), the user is able to live as usual (= no particular problem), and nothing in particular do not do.

  In the case of the pendant type handset 2, if the button is not pressed even after the specified time has passed, there is a possibility that some kind of abnormal situation has occurred. An abnormal report is made.

  In the cordless base unit 1 shown in FIG. 1, the main control unit 11 performs overall system control and signal processing. The base unit receiving unit 12 receives a radio signal from the pendant type handset 2. The base unit transmission unit 13 transmits a radio signal to the pendant type handset 2. The line control unit 14 controls incoming and outgoing calls on a general public line.

  In the pendant type handset 2, the main control unit 21 performs overall system control and signal processing. The slave unit receiver 22 receives a radio signal from the cordless master unit 1. The handset transmission unit 23 transmits a radio signal to the cordless base unit 1. The button unit 24 is a man-machine interface of the pendant type handset 2. The user notification unit “1-9” requests the user to press the button.

  2 and 3 are sequence charts showing an operation example of the simplified safety confirmation system according to the first embodiment of the present invention. The operation of the simplified safety confirmation system according to the first embodiment of the present invention will be described with reference to FIGS.

  First, a normal safety confirmation operation of the simplified safety confirmation system according to the first embodiment of the present invention will be described with reference to FIG.

  When it is time to generate a button press request event for the user (a1 in FIG. 2), the pendant type handset 2 first notifies the cordless base unit 1 of a “press request start” by radio (FIG. 2). A2).

  When the cordless master unit 1 receives the wireless notification from the pendant type slave unit 2, the cordless base unit 1 returns a response “OK” meaning that the wireless connection with the pendant type slave unit 2 has been normally established (a3 in FIG. 2).

  Upon receiving the response from the cordless master unit 1, the pendant type slave unit 2 starts a monitoring timer (a4 in FIG. 2) and starts a request operation (for example, alarm ringing) (a5 in FIG. 2). At the same time, the pendant type slave unit 2 monitors button pressing by the user.

  When the button is pressed (a6 in FIG. 2), the pendant type handset 2 stops the monitoring timer and the request operation (a7, a8 in FIG. 2), and “presses the button” to the cordless base unit 1. Is wirelessly notified (a9 in FIG. 2).

  In this case, the cordless master unit 1 does not do anything in particular, and returns a response “OK” meaning that the safety can be normally confirmed to the pendant type slave unit 2 (a10 in FIG. 2), and is in a standby state (the above-mentioned constant monitoring). Return to the state.

  Next, a case where a timeout occurs in the safety confirmation operation of the simplified safety confirmation system according to the first embodiment of the present invention will be described with reference to FIG.

  In the above-described safety confirmation operation (b1 to b5 in FIG. 3), the pendant type slave device 2 stops the request operation (b7 in FIG. 3) when the monitoring timer times out (b6 in FIG. 3). 1 is notified by radio of “timeout” (b8 in FIG. 3).

  When the cordless master unit 1 receives the “timeout” wireless notification from the pendant type slave unit 2, the cordless master unit 1 makes a call to the set telephone number (center telephone number) and notifies the center of “abnormality occurrence”. . Thereafter, the cordless master unit 1 returns a response “OK” meaning that “abnormality occurrence” has been notified to the center to the pendant type slave unit 2 (b9 in FIG. 3), and is in a standby state (the above-described constantly monitoring state). Return to.

  As described above, in the present embodiment, the pendant type slave unit 2 receives a radio signal from the cordless master unit 1 only after the pendant type slave unit 2 sends a command to the cordless master unit 1. Therefore, there is no need for the pendant type slave unit 2 to be always in a receiving state, the power consumption of the pendant type slave unit 2 can be suppressed, and the battery life can be extended.

  FIG. 4 is a sequence chart showing an operation example of the simple safety confirmation system according to the second embodiment of the present invention. The simplified safety confirmation system according to the second embodiment of the present invention has the same configuration as that of the simplified safety confirmation system according to the first embodiment of the present invention shown in FIG. A case where the machine 2 is out of the range of the cordless master unit 1 can be handled.

  A case where the pendant type handset 2 is outside the service area of the cordless base unit 1 in the safety check operation of the simple type safety check system according to the second embodiment of the present invention will be described with reference to FIG.

  When the pendant type handset 2 is outside the service area of the cordless base unit 1, the “push request start” sent by the pendant type handset 2 does not reach the cordless base unit 1. That is, even if the pendant type handset 2 starts a button press request, the result (“button press”, “timeout”) cannot be notified to the cordless base unit 1.

  Therefore, the pendant type handset 2 starts a response timer (c2 in FIG. 4) when transmitting “press request start” (c1 in FIG. 4), and does not receive a response from the cordless base unit 1 within a specified time. In the case (c3, c4 in FIG. 4), the user is informed that he is out of service area (c5 in FIG. 4).

  Thereafter, when the pendant type handset 2 returns to the service area (c6 in FIG. 4), the sequence from the “press request start” is executed again (c7 to c18 in FIG. 4).

  In this embodiment, a button press request operation such as an alarm ringing or wireless transmission to the cordless master unit 1 is not small in power consumption of the pendant type slave unit 2, so the wireless connection with the cordless master unit 1 is not started at the start of the event. By confirming availability, it is possible to avoid wasteful power consumption.
