Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a remote monitoring and control system for security such as crime prevention and disaster prevention in the home and for controlling home appliances.

[Prior Art] Conventional systems of this type include those shown in FIGS. 9 to 11. FIG. 9 is a diagram showing the configuration of a conventional remote control monitoring system based on Matsushita Electric Industrial ■'s light line HALS home controller (HY-120) and adapter (12-911) > (1) construction manual. in,
In the figure, (IOA) and (IOB) are respectively adapters, and (2) are these adapters (IOA>, (1
Loads and sensors connected to 0B>, (30) the home controller, (50) each adapter (IOA), (
IOB) and the home controller (30), and (70) are the respective adapters (IOA),
(IOB) own station address setting switch, and the home controller (30) has an operation display (91), an operation switch (92), a partner station (that is, an adapter (IOA),
(IOB)) is provided with an address switch (93), which superimposes a signal for data transmission onto the power line (50) and takes measures to prevent this signal from being transmitted outside the home. ) is also used as a data transmission line.

In addition, Figure 1O and Figure 11 respectively show this electric light line HA.
The address table and address number entry form attached to the LS and used when installing (or changing) this system are shown.

Each adapter (IOA), (IOB) and the home controller (30) are connected by a communication means using a power line (50), and each adapter (IOA), (IOB)
(IOB) includes loads and sensors that you want to monitor and control (
2) is connected and monitored by the operation display (91) of the home controller (30) or controlled by the operation switch (92).

On the other hand, in the home controller (30), the respective addresses of the loads and sensors (2) to be controlled or monitored are set in the partner station address switch (93), and these addresses are set in the respective adapters <IOA>, (10B)
The same address setting switch (70) is set. When you want to control or monitor each load or sensor (2), use the partner station address switch (93) of the home controller (30) to call up the adapter to which the desired load or sensor is connected.
), and controls and monitors loads and sensors through this adapter. Therefore, if there are loads or sensors that you want to control or monitor independently, it is necessary to assign individual addresses to each load or sensor.

Conventional remote monitoring and control systems have the above-mentioned configuration, so when installing or changing the system, it is necessary to check which one corresponds to the local address of each adapter (IOA) and (IOB). For example, enter the name of the load (or sensor) installed in the room in the address table shown in Figure 10, and make it correspond to the operation display (91) and operation switch (92) of the home controller (30). In order to do this, for example, check the adapter's own station address from the entries in the address table of Figure 10 such as "room" and "load" (or "sensor"), and then send the same address to the home controller (30). It is necessary to set the address as the station address, and the contents of the address must be set in the address number entry table in FIG. It becomes necessary to fill it out and securely store it. In other words,
If these tables are not filled in, it will be very difficult to add or change loads or sensors.

1 Problems to be Solved by the Invention] The conventional remote control monitoring system as described above is configured as described above, so when setting or changing the system, the address table and address number entry form are used to As user requirements become more diverse, more loads and sensors will be added after the system is set up, and each time the address table and address numbers for all adapters and home controllers will need to be set up. There was a problem in that the entry form had to be rewritten.

FIG. 4 is a flowchart for explaining the operation of the system according to the present invention, in which MC (3) initializes the RC number pointer and timer after a certain period of time when the system starts up, and (1), packets are sequentially sent to each RC (1) to request transmission of load and sensor (2) connection information and room code information. If the RC (1) corresponding to this RC number is not connected and the transmission from this RC (1) does not arrive, a timeout occurs and a similar packet is sent to RC (1) with the next RC number. Send out.

If the RC (1) corresponding to the RC number in question returns connection information, RC number information, and room code information for the sensor or load, set these information in the connection table and transfer it to the next RC number.
