DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail based on examples. FIG. 1 is a configuration diagram showing a radio paging system and an operation state monitoring device of the radio paging system according to an embodiment of the present invention.

In FIG. 1, a telephone set 11 can be connected to a radio paging exchange 13 via a public telephone network 12. The wireless paging exchange 13 can be connected to the local controller 14 according to the contents of the wireless paging when there is a wireless paging. The local control device 14 can drive the transmitting station 15 in accordance with the content of the wireless call. The transmitting station 15 can transmit a paging radio wave into the radio paging area 16 in accordance with the drive control from the area control device 14. An unspecified number of ordinary people are working with the pager 17 in the wireless calling area 16. Further, a monitoring pager 20 is arranged in the wireless calling area 16.

The monitoring pager 20 includes a decoding circuit (call signal decoding unit) 21 for checking the normality of a signal, a timer circuit (timer unit) 22 for monitoring the presence or absence of a call signal within a predetermined time, and a call signal. An alarm circuit (alarm unit) 23 for notifying an abnormality when the abnormality detection information is output from the decoding unit 21 or the timer unit 22 is provided.

Here, when the paging signal decoding section 21 receives the paging signal, for example, it detects whether the paging signal has a predetermined signal format, and can output abnormality information when the paging signal is not in the predetermined format. It is configured as follows.

The timer section 22 can set a timer expiration value in advance in accordance with traffic. The timer unit 22 counts time from the reset time, and is reset if there is a calling signal before the expiration value of the timer elapses. If there is no calling signal until the expiration value of the timer elapses, the timer unit 22 times out. I have.

The call of the wireless pager 17 is as follows.
It is performed as follows. That is, the calling party is the telephone 1
The first receiver is off-hook, and a call number for a predetermined pager 17 is dialed in through a push button.
Then, the telephone 11 is connected to the paging exchange 13 via the public telephone network 12. In the paging exchange 13, announcements such as "Please input a message.", "Please press the sharp key twice and then hang up the receiver and wait for a call from the other party" are made.

Then, the caller presses the push button of the telephone set 11, inputs a predetermined message, and finally inputs the sharp twice, and then goes on-hook the receiver.

Then, the paging exchange 13 edits the paging data in accordance with the calling number and sends it to the local control unit 14. The regional control device 14 edits the paging data into transmission data and sends the data to the transmission station 15. The transmitting station 15 transmits the transmission data as radio waves. As a result, a predetermined pager 17 in the wireless call area 16 is called.

Next, the operation of the operating state monitoring device of this system will be described. A call to an unspecified number of pagers 17 in the radio call area 16 always occurs. The monitoring pager 20 receives a calling signal to an unspecified number of pagers that is constantly occurring, and a calling signal decoding unit 21 checks the normality of the data. Here, it is not necessary to check all the paging signals, and in this embodiment, the first paging signal for each paging batch is targeted.

Further, in the monitoring pager 20, the timer section 22 monitors that no calling signal is generated.
That is, the timer unit 22 counts the time from the reset time, and is reset if there is a call signal before the timer expiration value elapses, and outputs a timeout signal if there is no call signal until the timer expiration value elapses. .

The paging signal decoding section 21 issues a reset instruction to the timer section 22 every time a paging signal is received.
By this reset instruction, the timer section 22 clears the time measurement. In this example, the timer expiration value of the timer section 22 is set to 3 minutes. If the ringing signal does not last for 3 minutes,
The timer section 22 times out and the abnormality information is sent to the alarm section 2
Enter 3 Thus, the alarm unit 23 issues an alarm. Further, the calling signal decoding unit 21 checks the normality of the data of the calling signal, and if there is an abnormality, inputs abnormality information to the alarm unit 23. Thus, the alarm unit 23 issues an alarm.

According to the embodiment described above, (a) it is not necessary to add a device capable of transmitting a signal or the like for monitoring the operation state in the radio paging exchange 13; (b)
There are advantages that it can be easily applied to an active paging system and (c) it is not necessary to change the monitoring method for each type of paging system.

FIG. 2 shows another embodiment of the present invention. The wireless paging system of this embodiment is a telephone 1 shown in FIG.
1, since it has exactly the same configuration as the wireless paging system including the public telephone network 12, the paging exchange 13, the local control unit 14, and the transmitting station 15, it is not shown.

The operation state monitoring device of the system shown in FIG. 2 is greatly different from the operation state monitoring device of FIG. 1 in that the timer expiration value of the timer section 22a can be changed and the timer expiration value can be changed with time. It is in the point which was made. This will be described in detail below.

The monitoring pager 20a includes a calling signal decoding unit 21 for checking the normality of a signal, and a timer for setting the timer expiration value variably and monitoring the presence or absence of a calling signal within the set time. Unit 22a, an alarm unit 23 for notifying an abnormality when abnormality detection information is output from the call signal decoding unit 21 or the timer unit 22,
A time section 24 for providing time data.

Here, the timer section 22a is reset by a call signal. The timer section 22a keeps measuring the time from the reset point, and is reset if there is a call signal before the set time has elapsed. If there is no signal, it will time out. Also, the timer unit 22a
, The timer expiration value can be automatically changed according to the time of the time section 24.

When a signal from, for example, midnight to 7:00 am is output by the time unit 24, the timer unit 2
The timer expiration value of 2a is set to 30 minutes. Further, the timer section 22a sets the timer expiration value of the timer section 22a to 3 minutes from, for example, 7:00 am to 0:00 am by the time section 24. When the timer expiration value of the timer section 22a is automatically set in this way, it is possible to reliably and labor-saving monitoring.

According to this embodiment, the timer section 22a
Although the timer expiration value is automatically set by the time of the time section 24, it may be set manually by the time.
