FIG. 6 is a block diagram showing the main part of the internal circuit of the first embodiment of the portable radio device 4 of the present invention. In the figure, reference numeral 20 indicates whether or not the fall detection signal input from the fall detection unit 2 is information that should be truly issued, cancel it if it is an erroneous report, and fall only when it should be true. It is a fall alarm control unit for notifying a signal to the wireless unit 3. The fall warning control unit 20 is inserted between the wireless unit 3 and the fall detection unit 2.

The internal configuration of the fall alarm control unit 20, which is a characteristic feature of this embodiment, will be described with reference to FIG. As shown in FIG. 7, the fall alert control unit 20 is composed of a fall alert determination means 21, a fall alert advance notice means 22, a time monitoring means 23, and a fall alert cancel switch 24.

The fall alert notification means 22 is connected to the fall alert determination means 21 and is means for giving notice to the wearer of the fall alert. Specifically, it is configured by a sounding medium such as a buzzer, a light emitting medium such as an LED, and the like, and has an effect that the wearer can detect the fall alarm by hearing or sight in advance.

The time monitoring means 23 is a fall warning determination means 2
It is configured by using a timer LSI or the like which is connected to 1 and is capable of electrically measuring a fixed time. The time monitoring unit 23 is used to generate a certain grace period between the fall detection unit 2 detecting a fall and the wireless unit 3 issuing a fall alarm. Since this grace period is generated, there is an effect that the carrier can use the fall reporting cancellation switch 24 to cancel the fall reporting.

The fall alarm cancel switch 24 is a mechanical switch connected to the fall alarm judging means 21, and when the wearer puts this switch in a short-circuited state, the fall alarm judging means 21 detects from the fall detector. There is an effect that it is possible to judge that the fall detection information that has been received is erroneous information and stop the reporting in advance.

FIG. 8 is an operation flowchart in the embodiment of the present invention shown in FIG. The operation of this program will be described with reference to FIG. (Step 100) Whether or not fall detection information is received from the fall detection unit 2 is monitored. When the fall detection information is not received, it loops without doing anything. When the fall detection information is received, the process proceeds to step 110. (Step 110) Time monitoring is started. A grace time, for example, 20 seconds is given to the time monitoring means 23 as an initial value. After that, the time monitoring means 23 starts time measurement. (Step 120) After the grace period has elapsed, in order to make the wearer recognize that a fall alert will be issued, the fall alert advance notice means 22
To start. For example, a buzzer sounds or an LED emits light. (Step 121) It is monitored whether or not the fall alarm cancellation switch 24 has been pressed. Due to the effect of step 120, when the carrier knows the notice of the report and determines that the report is unnecessary, the fall report cancel switch is pressed and the process proceeds to step 122. If the fall alarm cancellation switch 24 is not pressed, step 125 is performed.
Go to.

(Step 122) This is the case where the fall alarm cancellation switch 24 is pressed. In this case, the fall alert notification means 22 is immediately stopped (the buzzer stops, LED
Even if the light is turned off, etc., the fall detection information (fall signal) received from the fall detection unit 2 is still active,
Further, since it is immediately determined in step 100 that the fall signal has been received, the fall detection unit 2 is instructed to reset the fall detection information (fall signal). The latch of the fall signal is released. (Step 125) This is the process when the carrier cancels the overturned state of the wireless device 4 without pressing the overturning report cancellation switch 24. In this case, since the fall detection information from the fall detection unit 2 is reset, it is monitored whether or not the fall detection information from the fall detection unit 2 is continuously active. When the fall detection information (fall signal) is reset, the process proceeds to step 150. Otherwise, step 1
Proceed to 30. (Step 130) It is determined whether or not the grace time set in Step 110 has elapsed. If the grace period has not elapsed, steps 121 and thereafter are repeated. If the grace period has elapsed, the process moves to step 140. (Step 140) The fall signal is notified to the wireless unit 3.
This is the case where no cancellation operation was made within the grace period after the notice of a fall alarm was issued. (Step 150) This process is performed when the fall alarm cancel switch 24 is pressed or the fall detection information (fall signal) received from the fall detection unit 2 is reset. In this case, the fall warning notice means 22 is immediately stopped (buzzer sound is stopped, LED is turned off, etc.).
