[0020]

FIG. 1 shows a first embodiment of the present invention.
A description will be given based on FIG. FIG. 1 is a system configuration diagram,
FIG. 2 is a configuration diagram of the monitoring control device.

As shown in FIG. 1, the monitoring and control device connects lighting equipment, air conditioning equipment, and the like as equipment equipment 10, and enables on / off control of switches 11, 11 near the equipment equipment 10. ing. The monitoring control device is LA
N, and the personal computer 12,
.. Can also control the equipment 10.

As shown in FIG. 2 and FIG. 6, the monitoring control device uses the unique “equipment ID” as an index for the equipment connected to the equipment system, and sets the “current state”.
And a status table 6 for managing information of the "request source" controlled to that status. Further, there is provided a priority setting table 7 for managing the "priority" of the request source when transitioning from the first state to the second state using the equipment 10 as a unique "device ID" as an index.

The CPU 1 executes the monitoring control program 51 to decode a signal input from the LAN interface unit 3 and, if the request is for control of the equipment 10, the request source (current request source), the control target device, Request status information is
Expand on M2. Further, the CPU 1 searches the state table 6 for information on the current state of the device to be controlled and information on the request source that controlled the state (this is referred to as a previous request source) and extracts it.

The CPU 1 searches the priority order setting table 7 using the control target device, the requested state transition, the previous request source, and the current request source as keys, and determines whether or not the current control can be performed in priority order. I do.

As a result of the determination, if control is possible, the CPU 1 transmits a control command from the equipment system interface unit 4 to the equipment system. If control is not possible due to low priority, appropriate error processing is executed (see FIG. 3).

As described above, the RAM 2 temporarily stores the result of decoding the contents of the request source packet, and is used for comparison with the table information.

The LAN interface unit 3 is a connection unit with a network such as an Ethernet interface, and assumes a standard protocol such as TCP / IP as an upper layer protocol. Extract the data of the received signal,
Deliver to CPU1. It also sends the data passed from the CPU 1 to the LAN.

The equipment system interface unit 4 is B
A connection with devices to be managed such as A, HA, FA, etc.
The data of the received signal is extracted and delivered to the CPU 1. It also sends the data passed from the CPU 1 to the equipment system.

The file 5 contains a monitoring control program 5
1. A configuration file 52 necessary for operating the monitoring control device, and a GUI construction content 53 to be displayed on a LAN personal computer are recorded.

The file 6 manages the current state and information on the request source that controlled the state by using the unique equipment ID of the equipment 10 connected to the equipment system as an index. In the case of claims 9, 10, 11, and 12,
Further, the set key information is added, and the priority order setting table 7 becomes unnecessary. In claim 11, the set time information is added, and in claim 12, the set time information is further added.

The file 7 manages the priority of the request source when transitioning from the first state to the second state, using the equipment device as a unique device ID as an index. In the case of claims 3, 4, 5, as the priority of the request source, information unique to the device is entered. For example, for a TCP / IP network, I
The P address corresponds to this. In the case of claims 6, 7, and 8, information unique to the user is entered. For example, a user ID corresponds to this (in the case of a user ID, confirmation with a password is required as normal authentication).

This file 7 can be set and modified from the MMI of the monitoring and control device or a device on the network.

According to the second aspect, the information of the file 7 is managed by a separate information management device, and does not exist in the monitoring control device. In this case, to confirm the validity of the control, the CP
U1 inquires of the information management device on the network about the priority setting data via the LAN interface unit 3.

(Operation) The operation of the present monitoring and control apparatus program will be described with reference to the processing flow of FIG. When a control request is issued from a device on the network, information on the request source, the device to be controlled, and the request state is extracted (step
1).

The status table and the priority setting table are searched to determine the validity of the control. Alternatively, the key information is requested and the validity is determined (step 2).

If it is valid, control is executed (step
3). If it is improper (low priority), control is not performed and appropriate error processing is performed (step 4).

(Embodiment) The LAN side has a network configuration of TCP / IP and Ethernet, and WWW (World)
Wide Web) realizes a man-machine interface for monitoring and control. The management target is a lighting control device. The monitoring control program 51 at this time is HTTP
It becomes a lighting control program by server software and GGI, and GUI (Graphical User Inte
rface) Construction content 52 is HTML, Java
a, JavaScript. In the configuration information 52, setting items such as network information of the monitoring control device (HTTP server) itself, browser access right information, and setting of the number of server tasks are set.

The lighting control system has a control unit 13 for decoding a request command when the switch 11 or the like is operated, and transmits a control command to the lighting to be controlled. In the present monitoring and control device, a request command is transmitted to the control unit 13 for actual control, similarly to the switch 11. Therefore, the system operates independently even if the monitoring control device is not connected.

Example (1). FIG. 6 shows the states of the state table and the priority setting table. Priorities are set between the IP addresses of (browser) devices on the network. As an example, two types of IP-A and IP-B are assumed for the purpose of simplification (however, A and B may be individual addresses or subnet addresses). The state transition is
There are two types: ON → OFF and OFF → ON. In addition, there is a device for which a priority is not set.

The devices ID1 and ID2 are lights for the conference room A, and the device having the IP-A is a network-connected personal computer installed in the conference room A. IP-B is assumed to be installed in a remote office. In this case, the lighting of the conference room A can be controlled from off to on without any restrictions. However, the control from ON to OFF depends on the request source that has turned ON. That is, if the IP-B is turned on, the IP-B
Both A and IP-B can be turned off. However, if the IP-A is turned on, it cannot be turned off from the IP-B, and if it is desired to be turned off, it must be executed from the IP-A.

This setting prevents the user of the conference room A from being accidentally turned off from a remote device (IP-B) during the conference room.

Example (2). Assume the same conference room as above. FIG. 7 shows the states of the state table and the priority setting table.
Shown in For the device ID1 and ID2, the time during which the same priority order as in (1) is valid (time since turning on, interval) is set to 1 hour.

In this case, if the ON-control is performed by the IP-A, the off-control cannot be initially performed from the IP-B, or the priority becomes invalid one hour after the ON-control, and the IP-A becomes invalid.
-B can be turned off.

According to this setting, if the user of the conference room A forgets to turn off the lighting after the conference, remote control from the browser can be performed one hour later, thereby realizing energy saving.

Example (3). Assume the same conference room as above. FIG. 8 shows the states of the state table and the priority setting table.
Shown in The device ID1 and ID2 have the same priority order as in (1) and the time when the priority order is valid is 22:00.

In this case, if it is IP-A that the on-control was performed before 22:00, the off-control cannot be performed from IP-B at first, or if the time reaches 22:00, this priority becomes invalid, and the IP-A becomes invalid. B can be turned off.

With this setting, if the user in the conference room A forgets to turn off the lighting after the conference, remote control from the browser becomes possible after 22:00, and energy saving can be realized.

Example (4). The devices ID1 and ID2 are illuminations for a showroom. FIG. 9 shows the states of the state table and the priority setting table. In this case, the priority is set to the user ID, and the priority is set for the control from ON to OFF. Here, for the purpose of simplification, the user ID is set to "sup
er "and" users ", and a unique password exists as authentication for each. In addition, su
Only the showroom manager knows the password for per.

When the showroom manager turns on the lighting of the showroom, it cannot be turned off by anyone other than the manager (users level). For example, after the showroom is closed, the responsible person turns off the lights, which enables individual-dependent lighting control, thereby improving malfunctions and improving security.

Example (5). Next, a line of the FA system is assumed. FIG. 10 shows the status table. The administrator performed off-control from a personal computer in a remote control room in order to perform maintenance work on the manufacturing facilities of the devices ID1 and ID2. At that time, key information was set. Although the key information is displayed as it is in FIG. 10, the security is improved by displaying the key information in an encrypted form in an actual file. Since this key information is information set by the administrator as he or she can think of, it is possible to prevent another person from inputting and turning on the key information. Therefore, the administrator can perform the maintenance work of the manufacturing equipment with peace of mind, and the manager himself turns on the control after the work is completed. This prevents the manufacturing equipment from being erroneously operated by another person during the operation, thereby improving safety.

Example (6). Next, an example is shown in a building group management system (see FIG. 5). A plurality of buildings are monitored and controlled by a management computer of a remote group management center via an ISDN public network. The building to be managed is 22 at night
By the time all employees have left, monitoring and control will be entrusted to the group management center.

Here, the same priority order setting table as in (3) of the example is set. Here, IP-A refers to all the personal computers in the managed building (specifying the subnet address),
-B is the management computer of the group management center. 22
When the time has passed, it is possible to turn off the lights from the management computer, and it is possible to turn off the lights that have been forgotten to be turned off all at once.
