Abstract

PURPOSE:To easily restore as data contents of a memory circuit that are lost by a service interruption by calling the destructed data out of an external data base via a telephone circuit and restoring the contents of the memory circuit. CONSTITUTION:A memory circuit 7 which stores the data on the system function, etc., for control of each terminal equipment is provided to a signal control part 6 which controls the terminal equipment (a telephone terminal 3, a home controller 2, etc.) of a master device 1. At the time of a service interruption occurs, the device 1 first checks whether the contents of the circuit 7 are correct or not. In case the contents of the circuit 7 are destructed, a MODEM 8 extracts the data on the system function, etc., registered to an external data base A via a telephone circuit L and a network control unit (NCU) 9. Then the part 6 restores the destructed contents of the circuit 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a load control system that controls a load according to data in a memory circuit that stores system functions and the like.

1 Background Art 1 FIG. 3 shows a configuration diagram of a home system which is a conventional load control system. , No. 2 home telephone system includes a signal control unit 6 for controlling the terminal device of the thumb 1, and a memory circuit 7 storing data such as system functions for controlling each terminal device. In this case, the loads on the memory circuit 7 are the thumb 1 and the terminal device. In this conventional example, the terminal equipment includes a 'Ki talk terminal 3, a control load 4, a sensor 5, and a home controller 2 that has these functions in a concentrated manner. Here, if the home controller 2 is large, it can also display a map of the room. The system configuration of the entire home telephone system is stored in the memory circuit 7 of the thumb 1 at the time of setting, and the thumb 1 receives a control signal for controlling the terminal via the control signal #l+ of the path line to the terminal. Equipped with transmission function, and thumb 1 is between telephones #aL
This type of phone call is connected to a telephone office at the telephone line, and calls are made to outside parties via this telephone line, or calls are made between the thumb 1 and the terminal device via the pass line audio number IC2. In case of a power outage, the home telephone system has a thumbs up.
The memory circuit 7 is backed up, but if the contents of the memory circuit 7 are lost for some reason,
It is necessary to input all the settings into the memory circuit 7 again, and the data settings are complicated, requiring time and effort for manual work. However, there was a problem in that the user could not restore the system and had to ask a maintenance company to do the work, which resulted in high costs.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned points, and its purpose is to easily restore the data contents when the contents of the memory circuit are lost due to a power outage. Our goal is to provide a load control system that can.

Disclosure of the Invention 1 (Example) Figures 1 and 2 are diagrams showing an example of the present invention.
In this embodiment, thumb 1 is connected to external database 8 via telephone line I-, and data for restoring the contents of memory circuit 7 is exchanged between external database 8 and thumb 1 via telephone line #XL. The thumb 1 is equipped with a modem 8. ,
Further, in this embodiment, the thumb 1 has a function of checking the contents of the memory circuit 7.

Now, if a power outage occurs, the thumb 1 checks whether the contents of the memory circuit 7 are correct, as shown in FIG. Also, if the memory circuit 7 is damaged, the modem 8 automatically disconnects it! 'lS7' - queries the database A, that is, retrieves data such as system functions registered in the external database Al using the modem 8 via the telephone line and network control unit 9, and destroys it using the signal control unit 6. ij! memory circuit 7
This is to restore the contents of the file. Further, immediately after the home telephone system of this embodiment is newly installed, the contents of the memory circuit 7 can be automatically registered in the external database 8 via the modem 8. Furthermore, the load control system of this embodiment can also change the contents of the memory circuit 7 from the thumb 1 or the home controller 2 to the external database 8. For example, if the contents of the memory circuit 7 change due to a partial change in the system configuration, etc., the new contents of the memory circuit 7 can be transferred from the thumb 1 to the external database 8 via the modem 8. It is possible to register. This external database A is managed by the manufacturer, maintenance company, etc. In this way, in the past, when the contents of the memory circuit 7 were destroyed due to a power outage, etc., it was necessary for a maintenance company to restore the contents of the memory circuit 7, but according to this embodiment, the contents of the memory circuit 7 are automatically restored to the modem 8. The contents of the damaged memory circuit 7 can be restored by querying the external database 8 via the telephone line mL. It goes without saying that this embodiment can also be applied to a terminal device such as the home controller 2 which has substantially the same functions as the thumb 1.

[Effects of the Invention 1] As described above, the present invention provides a load control system that includes a memory circuit in which an external database is stored in advance and controls the load according to the data of this memory circuit. When the memory circuit is destroyed, the contents of the memory circuit are restored by calling the destroyed data from an external database via the telephone line. By querying through the J! and retrieving the contents of the destroyed memory circuit from an external database, the memory circuit can be destroyed. ! Therefore, it is not necessary for a maintenance company to restore the contents of the memory circuit, resulting in an effect of saving cost and time.
