Abstract

PURPOSE:To monitor the operating state of a radio equipment in a line connection terminal station from a line connection control station by arranging a monitoring transmitting equipment for transmitting a monitor signal in the line connection terminal station and arranging a monitoring receiving equipment for receiving the monitor signal in the line connection control station. CONSTITUTION:In the line connection control station 1, a test calling code is sent from a control part 12 to a line control device 3. In the line connection terminal station 6, the test calling code is received, and at the time of deciding that the received code is sent for the self-station, a line control device 8 sends a test call response code to the station 1 and successively starts a control part 17 and a monitor signal sending circuit 16. At the time of receiving said test call response signal by the station 1, the control part 12 connects the line to a monitor signal receiving circuit 11. When a monitor signal from a radio equipment 7 is received by the circuit 11, the control part 12 restores a switching circuit 10 and commands the device 3 to restore the line connection.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a single radio telephone system monitoring system, and particularly to a single radio telephone system in which a line connection control station and a line connection terminal station are connected via a wireless line. The present invention relates to a single radio telephone system monitoring method for performing line connection operation tests and monitoring the operating status of radio equipment in the system.

[Conventional technology]

Conventionally, in this type of single radio telephone system, in order to check whether the line connection between the line connection control station and the line connection terminal station is established normally, the line connection control station side and the line connection terminal station side are connected to each other. It has a function to perform a line connection test with the wireless line, and is operated while checking whether the line connection is properly established when the wireless line is empty.

[Problem to be solved by the invention]

The conventional single radio telephone system described above can perform a line connection test to check whether the line connection between the line connection control station and the line connection terminal station is established normally. Another problem is that the line connection control station cannot monitor the operating status of the wireless equipment of the terminal station.

SUMMARY OF THE INVENTION An object of the present invention is to provide a single radio telephone system monitoring method that allows a line connection control station to monitor the operating status of a radio device in a line connection terminal station.

[Means to solve the problem]

The single radio telephone system monitoring method of the present invention includes (A) a first switching circuit that switches lines, a supervisory signal transmitting circuit that transmits a supervisory signal indicating the operating state of a wireless device, the first switching circuit, and (B) a second switching circuit that switches the line; and a monitor that receives the supervisory signal; (B) a second switching circuit that switches the line; The monitoring receiving device is installed in a line connection control station and includes a signal receiving circuit and a second control unit that controls operations of the second switching circuit and the monitoring signal receiving circuit.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

The single radio telephone system monitoring system shown in FIG. 1 is comprised of a monitoring/receiving device 5 installed in a line connection control station 1 and a monitoring transmitting device 9 installed in a line connection terminal station 6.

The monitoring and receiving device 5 also includes a switching circuit 10 for switching lines;
A monitoring signal receiving circuit 11 that receives a monitoring signal, and a switching circuit 1
0 and the control unit 1 that controls the operation of the supervisory signal receiving circuit 11.
The monitoring transmitting device 9 includes a switching circuit 15 that switches lines, a monitoring signal transmitting circuit 16 that sends out a monitoring signal, and a control section 17 that controls the operation of the switching circuit 15 and the monitoring signal transmitting circuit 16. has been done.

Next, the operation will be explained.

In a normal call connection from the line connection control station 1, when a call is made from the telephone 13, the dial signal passed through the exchange 4 is converted into a call code at the line control device 3, and then transmitted from the radio device 2. 0 line connection terminal station 6
Then, the call code received by the wireless device 7 is verified by the line control device 8, and the corresponding telephone 14 is called.

When the telephone 14 is hooked off, a response signal is sent from the line control device 8, and the wireless bag W7 sends a response signal to the line connection control station 1.
In the 0-line connection control station 1, the response signal received by the wireless device 2 is converted into a signal in the line control device 3, the ring tone of the telephone 13 is stopped in the exchange 4, and the communication path is connected.

Now, suppose that a line connection test operation is performed between the line connection control station 1 and the line connection terminal station 6 when the wireless line is in an empty state.

In the line connection control station 1, the control unit 12 sends a test call code to the line control device 3 for the target terminal station for the line connection test.0 When the line connection terminal station 6 receives the test call code, the line control device 8 compares the received test call code with the call code assigned to the own station, and when they match, determines that the terminal station to which the line connection test is to be performed is the own station;
The specified line connection is made, a test call response code is sent to the line connection control station 1, and the control unit 17 of the monitoring and transmitting device 9 is activated. The activated control unit 17 switches the switching circuit 1
The monitoring signal transmitting circuit 16 is switched by switching the contact 5 from the a side to the b side.
Start.

The line connection control station 1 receives the test call response signal from the line connection terminal station 6 and checks the line connection status with the line connection terminal station 6. The line is connected to the supervisory signal receiving circuit 11 by switching the contact point from a to b side.

When the supervisory signal receiving circuit 11 receives a supervisory signal indicating the status monitoring information of the wireless device 7 sent from the supervisory signal transmitting circuit 16 of the line connection terminal station 6, the control unit 12 switches the contact of the switching circuit 10 to the a side. At the same time, it instructs the line control device 3 to restore the line connection. In the line connection terminal station 6 as well, after a certain period of time, the control unit 17 restores the contact of the switching circuit 15 to the a side, and instructs the line control device 8 to restore the line connection to restore the original state.

〔Effect of the invention〕

As explained above, the present invention allows the line connection control station to perform a line connection test between the line connection control station and the line connection terminal station, and simultaneously monitor the status of the wireless device of the line connection terminal station. It has this effect.
