Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention monitors the signal transmission path of a home automation system in which each device constituting the system is given a unique number to distinguish it from other devices. The present invention relates to a power transmission line monitoring device.

2. Description of the Related Art In general, a home automation system for remotely controlling the power supply of loads such as lighting equipment and air conditioners in the home and for monitoring the status of the loads is configured as shown in FIG. In FIG. 3, la and 1b are loads in the home. 2a and 2b are connected to loads 1a and 1b, respectively, and load 1a according to the content of control signal 4 from signal transmission line 3.
・This is an adapter that controls 1b. Adapter 2a/2b
are assigned unique numbers (hereinafter referred to as addresses). A controller 5 controls and monitors the loads 1a and 1b in the home via the adapter 2 by transmitting a control signal 4 to the signal transmission line 3.

In such a home automation system, the controller 5 distinguishes the individual loads 1 (for example, the loads 1a and 1b) by the addresses given to the individual adapters, and controls and monitors them. Therefore, addresses must be assigned to each adapter without duplication, and a state in which the same address is assigned to multiple adapters in duplicate (hereinafter this state is referred to as one-address-duplicate state) correct control/monitoring cannot be carried out in this case.

To avoid this inconvenience, power line monitoring devices are connected to home automation systems.

The power line monitoring device detects when the home automation system is in an address duplication condition (for example, when multiple adapters are activated by a control signal sent by a controller to one adapter). It is a device to let people know.

FIG. 4 shows an example of the configuration of a conventional power transmission line monitoring device 6. As shown in FIG. Fourth
In the figure, reference numeral 7 denotes a monitoring means connected to the electrical transmission line 3 of the home automation system for monitoring address duplication. Reference numeral 8 denotes a display means for displaying whether or not there is an address duplication state in accordance with the monitoring result of the monitoring means 7, and for displaying the overlapping address when there is an address duplication state.

Problems to be Solved by the Invention In general, the address of an adapter is often assigned by an address setting switch included in the adapter, so the address duplication is caused by an error in the setting of this setting switch, or a problem with the contacts of this setting switch. Most of these occur due to aging. If the former is caused by an incorrect setting of the setting switch, address duplication will occur continuously, but
If the latter is due to age-related deterioration of the contacts, address duplication occurs intermittently (for example, address duplication may occur only in the middle of the night and for a short period of time due to changes in temperature). Conventional transmission line monitoring devices display duplicate addresses when the home automation system is in an address duplication state, but do not display anything when the home automation system is not in an address duplication state. Therefore, conventional transmission line monitoring devices are effective when address duplication occurs continuously, as in the former case, but are not suitable when address duplication occurs intermittently, as in the latter case. . In particular, when the period during which address duplication occurs is shorter than the period during which address duplication does not occur, it is extremely difficult to discover duplicate addresses.

The present invention solves these conventional problems,
To provide a transmission line monitoring device capable of displaying overlapping addresses not only during the period when the address duplication state is occurring but also during the period when the address duplication state does not occur when the address duplication state occurs intermittently. The purpose is to

Means for Solving the Problems In order to achieve this objective, the transmission line monitoring device of the present invention has the following features:
A monitoring means for monitoring whether addresses are duplicated; a storage means for storing the duplicated address if the address is duplicated according to the monitoring result of the monitoring means; and a display means for displaying the information.

Effect: With this configuration, the power transmission line monitoring device of the present invention can display and store the duplicate address when an address duplication occurs.

Therefore, according to the transmission path monitoring device of the present invention, even when address duplication occurs intermittently or instantaneously, duplicate addresses can be easily discovered by displaying the stored addresses. .

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. Reference numeral 9 denotes a power transmission line monitoring device, which includes the following elements. A monitoring means 10 is connected to the signal transmission line 3 and monitors whether or not the addresses of individual devices are duplicated. Reference numeral 12 denotes a storage means for storing overlapping addresses, if the addresses are overlapping, according to the monitoring result 11 of the monitoring means 10. 14 is a display means for displaying the memory contents 13 stored in the memory means 12, and is composed of a first indicator light 15 and a second indicator light 16 shown in FIG. The first indicator light 15 is for displaying a duplicate address when an address duplication condition is currently occurring in the home automation system. The second indicator light 16 is an indicator light that indicates whether the address is duplicated or has occurred in the past based on the memory contents 13 stored in the storage means 12. In the example of FIG. 2, the first indicator light is not displaying anything, indicating that no address duplication is currently occurring. Further, the second indicator light indicates that an address duplication has occurred in the past, and the duplicated address at that time was number 32.

Therefore, it can be seen that the home automation system to which this transmission monitoring device is connected is intermittently causing address duplication.

The operation of this embodiment will be explained below. When the monitoring means 10 detects that an address duplication state has occurred in the home automation system, the monitoring means 10 generates a monitoring result 11 indicating that an address duplication state has occurred and the number of the duplicated address. The information is transmitted to the storage means 12. The storage means 12 stores the duplicate address, and also informs the display means 14 that the address duplication has occurred and the stored contents (duplicate address) 13. The display means 14 displays the fact that address duplication has occurred in the home automation system and the duplicated address. Since this display is performed via the storage means 12, it can be performed according to the stored contents 13 even after the address duplication state has recovered to the normal state.

If it is discovered that the home automation system has a duplicate address, the address displayed by the power line monitoring device 9 (number 32 in the example in Figure 2) or the contact of the address setting switch may have deteriorated over time. For an adapter that has been assigned an address that can be a potential address, take measures such as assigning a new non-duplicate address or replacing the adapter to release the address duplication state. This allows home automation systems to be properly controlled and monitored.

In addition, after adding a switch to erase the memory contents 13 of the storage means 12 and canceling the address duplication state, both the first and second indicator lights are turned off until the next address duplication state occurs. It may also be possible to hide the display.

Effects of the Invention As described above, the power transmission path monitoring device of the present invention connects to the signal transmission path of a home automation system in which each device constituting the system is assigned a unique number to distinguish it from other devices. However, according to the monitoring means for monitoring whether the said number is duplicated or not, and the monitoring result of the said monitoring means, if the said number is duplicated, N is determined.
It is equipped with a storage means for storing the number stored in the storage means, and a display means for displaying the contents stored in the storage means, so that address duplication that occurs intermittently or instantaneously can be easily avoided. It is possible to find duplicate addresses in the home automation system, and is highly effective in maintaining and managing home automation systems.
