Abstract

PURPOSE:To detect the state and the cause of abnormality of a system with a telephone set and to shorten a time necessary for the restoration from a fault by monitoring the state of the communication between a communication line and a second interface with a diagnosing means, and confirming the result of the monitoring from a telephone set through a first interface at the time of the occurrence of a fault. CONSTITUTION:The control means 8 of the diagnosing, device 10 is connected to a telephone line 5 through the first interface I/F 6. On receiving a specific code signal predetermined from the telephone line 5 through the I/F 6, the device 10 actuates the diagnosing means 9, and connects it to the second I/F 7 via the means 8. This I/F 7 monitors the state of the communication on a communication line 1 and the state of function in order to read the address, etc. of a faulty terminal equipment. The results of the monitoring and the reading by the I/F 7 are transmitted the telephone line 5 via the means 8 and the I/F 6. Thus the time necessary for restoring from the fault is shortened.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a diagnostic device using a telephone line for a home automation system.

2. Description of the Related Art As shown in FIG. 3, a conventional home automation system sends a signal to an adapter 3a or an adapter 3b via a communication line 1 by operating a controller 2, thereby controlling an i-device 4a or a device 4b. The adapter 3a and the adapter 3b control the device 4a and the device 4, respectively.
The operating state of unit b is communicated to controller 2 via communication line 1, and sent to unit 3.

The controller 2 displays (monitors) the status of each of the devices 4a9 and 4b using indicator lights and the like (not shown).

At this time, the controller 2, adapter 3a, adapter 3
b are distinguished from each other using different index numbers (addresses), and therefore, the signals on the communication line 1 always include an address signal.

Problems that the invention aims to solve Removing faults requires special skills, and service personnel always have to go to the site, and the time, effort, and cost required from the occurrence of a fault to recovery is enormous.

The present invention solves the above problems and provides a means for easily discovering the cause of a communication failure when it occurs.

Means for Solving Problems The home automation system diagnostic device of the present invention includes a first interface that is located between a telephone line and a communication line and that transmits and receives signals to and from the telephone line; a second interface to perform, converting the reception number 4 of one interface into the transmission number 4 to the other interface, and controlling the two interfaces to connect the telephone line and the communication line; a control means; and a diagnostic means connected to the control means to monitor the communication state of the second interface and the communication line and to report the presence or absence of a communication abnormality to the telephone line via the control means and the first interface. Consists of.

In the above configuration, the diagnostic means monitors the communication state of the communication line and the second interface, and when a communication failure occurs, the telephone transmits the monitoring results of the diagnostic means from the telephone via the first interface. You can check it by Therefore, service personnel can now give accurate instructions to home automation system users without having to go to the site, reducing the time from communication failure to recovery.

5 Bae.

Labor and costs are significantly reduced.

Embodiment FIG. 1 is a block diagram showing an embodiment of a diagnostic device for a home automation system of the present invention.

In the same figure, the control means 8 is connected to the telephone line 6 via a first interface 6 and normally converts the signal received from the telephone line 6 to the communication line 1 via a second interface 7. Alternatively, the signal received from the communication line 1 is converted and sent to the telephone line 5 via the first interface 6. That is, the control means 8
The telephone line 6 and the communication line 1 are connected by controlling two interfaces 6.7.

Here, when the control means 8 receives a predetermined specific code signal from the telephone line 6 via the first interface 6, the diagnostic means 9 is activated and the second
It is connected to the interface 7 of the second interface 7 and monitors the functional status of the second interface 7 (for example, whether the operation is good or bad), the communication status page 6 on one communication line 1 (for example, whether there is a communication failure), and the terminal that is the cause of the failure. The control means 8 reads the address of 8.
The telephone line 6 is notified via the first interface 6 .

The above-mentioned parts constitute the diagnostic device 10 of the home automation system.

FIG. 2 is an example of a home automation system incorporating the diagnostic device 10.

In the figure, a controller 2, an adapter 3a, and an adapter 3b, which are system terminals, are connected to a communication line 1, and each has a different index number (address).

Here, if adapter 3a and adapter 3b have the same index number due to initial incorrect settings, normal communication over communication line 1 cannot be maintained.

At this time, if a specific code signal is sent from the telephone line 6 and the diagnostic device 1 of the home automation system is activated, it will be possible to determine whether the communication status on the communication line 1 is good or not, and whether the terminal (in this case the adapter) is the cause of the communication failure. ) 7base〉゛ index number usage status can be checked, and service personnel can immediately assess the situation and issue instructions to solve problems without having to go to the construction site of the home automation system.

Effects of the Invention As described above, according to the device of the present invention, even if a highly skilled service person is not present at the construction site of the home automation system, if an abnormality occurs in the system, the status of the system can be determined by telephone. It is possible to immediately know the cause of an abnormality and give instructions for resolving it, and the time, effort, and cost from the occurrence of a failure to the point of recovery can be greatly reduced, and its practical value is extremely high.
