The alarm device 260 operates under the control of the control node 262, for example, the monitoring camera 250 or the human sensor 240.
It has a function of notifying an abnormality in the facility based on information from the computer or an instruction from the management computer 100.
For example, when an abnormality occurs, the abnormality is notified by an alarm device, or when an abnormality occurs at night, the abnormality is notified by turning on all of the illumination lamps 210.

The control system network 270 is an autonomous distributed intelligent control network, and is an LON (Local
Operating Network), and various actuators, sensors, and the like are connected via the control nodes.

The gateway 280 has a communication platform LSI 500 therein and an information network 400

Next, the operation and operation of the above configuration will be described.

The management computer 100 is connected to the LON control system network 270 in each of the outdoor lighting / security systems 200 and 300 via the information network 400.
Via a gateway 280. As a result, in each of the outdoor lighting and crime prevention systems 200 and 300, the change of the timer setting time of the clock 220 and the setting of the optical sensor 230 are collectively changed while the remote location is present, with respect to the change of the sunshine time due to the seasonal change. Is what you can do. Also, by grasping the information in the outdoor lighting / security system at regular intervals, it is possible to remotely monitor whether or not there is a malfunction in the surrounding environment.

Next, the control of turning on / off the illuminating lamp will be described with reference to the flowchart of FIG.

Here, the terms used in the following are briefly explained. That is, “morning / noon” refers to a time period during which normal lighting 210 is not required, and “evening” refers to the light sensor 23.
A time zone to determine if lighting is necessary by 0,
"Night" refers to a time period during which the lighting lamp 210 needs to be turned on, and "midnight" refers to a time period during which there is little human traffic. “Light” related to the amount of light indicates that
"Dark" means the amount of light that requires the illumination lamp 210 in cloudy or rainy weather. Furthermore, the human motion is detected by the motion sensor 2 in the outdoor lighting / security system.
40 means to monitor / detect human traffic,
When there is no traffic, the "power saving operation" is performed by suppressing the brightness of the illumination lamp 210 or reducing the number of lighting.

Now, in such a system, at the start of the operation of the lighting system, the current time zone is determined by the clock 210 (step S302). Illumination light 210
If the time is not required ("Morning / Lunch"),
The optical sensor 230 measures the current amount of light ("bright" / "dark") to determine the necessity of turning on the illumination lamp 210 (step S304), and performs an operation ("" ON "(step S306) /" OFF "(step S308)). At the time of lighting, the lighting amount of the illumination lamp 210 is controlled based on the amount of ambient light.

After a predetermined time has elapsed, the time zone is measured again by the clock 220 (step S302), and the illumination lamp 210 is measured.
Even when the time period in which it is determined that lighting is necessary (“evening”), the lighting operation of the illuminating lamp by the optical sensor 230, that is, the amount of ambient light (“bright” / “dark”) Is determined (step S310). If the light amount is “bright” for the time period, the illumination lamp 210 is off (step S312), and the process proceeds to step S302. On the other hand, if the light amount is “dark”, the illumination lamp 210 is turned on, and the process proceeds to step S314.

In step S314, a time zone is determined by the clock 220 ("morning" / "night" / "midnight"). If the time zone is in the “night” state, the illuminator is in the lighting continuation state (step S316), and the process proceeds to step S314. In the case of “late night”, the human sensor 240
, The presence or absence of human traffic in the facility is checked (step S318). If there is traffic, the lighting is turned on (step S320). If traffic is not detected, the power saving operation of the lighting is performed (step S32).
2).

The flow of processing when an abnormal situation occurs in the facility will be described with reference to the flowchart of FIG.

For example, when the human sensor 240 detects the traffic of a person in the facility (step S402), the monitoring camera 2
50 starts shooting and sends the shot image information to the management computer 100 (step S40).
4). On the management computer 100 side, for example, if the administrator recognizes that an abnormal situation has occurred (step S4).
(YES in 06), the management computer 100 sends instruction information to activate the alarm device 260 (step S408). Thus, for example, an abnormality is notified by an alarm device, or in the case of an abnormality at night, all the illumination lamps 210 are turned on.

As described above, according to the present embodiment, it is possible to centrally monitor the lighting equipment and security of a plurality of parks, bicycle parking lots, arcade streets and the like at one place, thereby reducing the management cost.

FIG. 5 shows a modification of the embodiment of the present invention.
In the figure, the same parts / functions as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. In this modification, the control node 600
A communication platform LSI 500 is applied to each of the control nodes 600, and an illumination lamp 210, a clock 220, an optical sensor 230, a human sensor 240, a monitoring camera 250,
The alarm device 260 is configured to be controlled individually. The operation / action is the same as in the example shown in FIG.

[0033]

As described above in detail, according to the present invention, the control of the outdoor lighting equipment can be performed autonomously by the distributed intelligent control network independently of the management computer system, so that the system can be constructed at low cost. Since it is possible to control nighttime illumination, power consumption can be reduced by controlling the illumination light amount when it is not necessary. In addition, a security system conventionally constructed separately can be connected to the control network similarly, and the system can be simplified.

According to the present invention, a communication platform LSI integrated into one chip is used as a bridge for directly connecting a distributed control network and an information system network, so that lighting and security equipment existing at a plurality of remote locations are provided. Management / control can be performed centrally at one location, so that an inexpensive and simple management system can be realized.
