1 to 9 show an embodiment of the present invention. As shown in FIG. 1, the integrated supervisory control system of the present embodiment,
A human body detection system A including a plurality of sensors 1 that function as a crime prevention system at least at night, a lighting control system B that controls lighting of a plurality of lighting fixtures 2, and an air conditioning control system that controls operation of a plurality of air conditioners 3. It is constructed by combining multiple systems such as C. As other systems, a key management system D that manages the storage status of keys in the key box 4 and a sign system E that displays the usage status of a conference room, reception room, etc. on a plurality of display devices 5 are provided. There is. The system configuration of FIG. 1 is merely an example, and it goes without saying that other systems may be combined.

Each of the systems A to E is provided with a control device 6 to 10 composed of a CPU as a master unit, and each of the control devices 6 to 10 is a bus type transmission line L _0.
It is connected to a central control unit 11 composed of a CPU that performs comprehensive monitoring control of E to E or signal transmission control. In the following description, the control devices 6 to 10 of the above systems
Will be collectively referred to as a master unit.

The sensor 1, the lighting fixture 2, the air conditioner 3, the key box 4 and the display 5 have a function as a terminal of a so-called multiplex transmission system, and each has a unique address. .. In the following description, when these devices are collectively called, they will be called terminals. In addition, the setting of each unique address is provided by the DIP switch or E ² PROM provided in the part that functions as a terminal.
It can be set at any time, and can be set or changed at any time.

Then, each of the above-mentioned terminals is connected to each system.
2-wire transmission line L₁~ L _FiveConnect with
Each terminal can be accessed individually to control and operate the terminal.
The work status can be monitored. Where each
Transmission signal V sent from the base unit of the stems A to E to each terminal
_SIs a start signal indicating the start of signal transmission, as shown in FIG.
Pulse ST, mode data MD indicating signal mode,
Address indicating the address (8 bits) of the terminal to access
Data AD, load (in the case of this embodiment, the terminal itself is negative
Control data CD indicating the control content for controlling the
Checksum data CS for detecting transmission error and
Return signal period WT that sets the return waiting period from the terminal
Pulse-width modulated bipolar (± 24V) time division
It is transmitted by multiple signals.

Normally, the master unit sequentially transmits the transmission signal to each terminal unit to perform signal transmission. That is, when the master unit controls the operation of a specific terminal, the address of the corresponding terminal is set in the address data AD of the transmission signal, and the transmission signal is sent to each terminal. Then, when the address set in the address data AD of the transmission signal coincides with its own address, each terminal takes in the transmission signal and reads the contents of the control data CD following the address data AD.
Then, it operates according to the contents of the control data CD. For example, in the lighting control system, lighting and extinguishing control of the lighting fixture 2 (including dimming control in some cases) are performed, and in the air conditioning control system, operation and stop control of the air conditioner 3 (in this embodiment, the strength of the operating state is strong or weak). (Including variable control). Then, during the return signal period WT following the control data CD, the monitoring data indicating the operation status is returned to the parent device. For example, in the case of the human body detection system A, the control device 6 can determine the human body detection status of each sensor 1 from this monitoring data, and the key management system D can display the storage status of the keys in the key box 4. The control device 7 can make the determination.

In the case of controlling the operation of a plurality of terminals, the master unit sequentially sets the address data AD in a variable manner according to the corresponding terminal, and controls the operation of the plurality of terminals in the same manner as the above case. Are performed sequentially. By doing so, the operations of the terminals can be centrally controlled by the master devices A to E of each system, and the operational status can be centrally monitored. By the way, in this type of multiplex transmission system, when the terminal urgently wants to send a return signal to the master unit, as shown in FIG. 2, it is synchronized with the start pulse ST and shown in FIG. It is possible to return the monitoring data and the like even if the master unit does not make a selection by transmitting the interrupt pulse Vi and issuing an interrupt request.

At this time, the master unit receiving the interrupt pulse Vi sets the mode signal MD of the transmission signal in the interrupt address polling mode and transmits it to specify the interrupt request terminal unit. When the interrupt request terminal is specified, the master sets the mode signal MD of the transmission signal to the monitor mode, sets the address of the interrupt request terminal to the address signal AD, and sets the interrupt request terminal. Receive a return signal from. Upon receiving this return signal, the master sets the mode signal in the response mode and transmits it to the interrupt request terminal, stops the transmission of the interrupt pulse Vi from the interrupt request terminal, and ends the interrupt processing. To do.

The above is a description of signal transmission for each of the systems A to E, but for the overall supervisory control system as a whole,
The master unit of each of the systems A to E is the terminal unit in the case of the above-mentioned signal transmission, and the central control unit 11 is the master unit. That is, in the case of the present embodiment, the entire system is configured to transmit information by multiplex transmission. However, in some cases, some of the systems may be systems that do not perform multiplex transmission.

In the integrated supervisory control system of this embodiment, the respective systems A to E are organically connected. For example, the result of monitoring the human body detection status of each sensor 1 by the human body detection system A is given to the lighting control system B and the air conditioning control system C. The monitoring result of the human body detection sensor A is given to the sign system E. For example, when the monitoring result of the human body detection status of each sensor 1 by the human body detection system A is given to the lighting control system B and the air conditioning control system C as described above, the human body detection system A used as a crime prevention system at night is specified. It can be used to detect the presence of a human body in space. By doing so, the lighting control system B can perform automatic lighting control of the lighting fixture 2 in accordance with the monitoring result indicating the human body detection status of the human body detection system A. Further, in the air conditioning control system C, the air conditioner 3 can be automatically operated according to the monitoring result of the human body detection system A.

By the way, each sensor 1 of the human body detection system A is provided in plural in a specific space, for example, in each room,
If the lighting device 2 is turned on according to the human body detection condition of the sensor 1, that is, the lighting device 2 in a predetermined area corresponding to the sensor 1 detecting the human body is turned on, it is possible to detect the presence of a person. Instead, the lighting device 2 is not turned on unnecessarily (so-called thinning-out lighting can be performed), and thus an energy saving effect can be expected. Further, the air conditioner 3 can be similarly thinned out.

This point will be described with reference to FIG. here,
An outer frame surrounding the whole shows a space to which this comprehensive monitoring and control system is applied, and each of the partitioned spaces a to f shows a specific space such as a room. Then, in each of the specific spaces a to f,
A plurality of sensors 1 indicated by circles are arranged. Now, assuming that the human body is detected by the shaded sensor 1 of the space c in the figure, the lighting fixture 2 corresponding to this sensor 1 is turned on. In addition, at the time of this lighting, you may use the pattern control which carries out batch lighting control of several arbitrary lighting fixtures. For example, when the output of any one of the sensors 1 is obtained, a plurality of lighting fixtures 2 for only a predetermined block in a specific space are provided.
May be turned on, or the lighting fixture 2 may be turned on alternately. In addition, when there are a plurality of air conditioners 3 in this space, the air conditioner 3 is operated in a state in which the area where the human body is detected by the sensor 1 can be efficiently performed. You can also do it.

Further, when a plurality of sensors 1 are arranged in a specific space, the number of persons existing in the specific space based on the human body detection status of each sensor 1, that is, the number of persons existing in the specific space depends on the frequency of human body detection. It is possible to determine whether the number of people to do is large or small. Therefore, according to the number of persons existing in the specific space, the air conditioner 3 is controlled by the air conditioning control system B.
The air conditioning level may be variably controlled.
With this configuration, comfortable air conditioning can be performed according to the number of people.

Here, a specific description of the human body detection system A in the case where the control device 6 is provided with the function of judging the number of persons is described below. As shown in FIG. 4, the sensor 1 includes a human body sensing unit 1a that senses a human body, and a terminal function unit that converts the sensing signal into a transmission signal and performs signal transmission by the above-described time division multiplex transmission with the control device 6. 1b and. The human body detection unit 1a also has a function of performing sensing signal processing. As shown in FIG. 5, the terminal function unit 1b includes a detection unit 31 that detects a sensing signal and a detection unit 3 that detects the detection signal.
A transmission unit 32 that performs signal transmission with the control device according to the output of 1; a power supply unit 33 that creates a constant voltage from the transmission signal superimposed on the transmission line L ₁ and supplies it to each unit as a power source;
The current limiting circuit section 34 limits the current supplied to the human body sensing section 1a.

As shown in FIG. 6, the control device 6 reads the monitoring data from each sensor 1 and determines the human body detection status of each sensor 1. Then, the number of times the human body detection output of each sensor 1 is obtained is counted. That is, the number of persons existing in the specific space is judged by this counting. Then, this counting result is sent to the control device 8 of the air conditioning control system C as output data. In this way, the air conditioning control system B can be adjusted according to the number of people in the specific space.
Thus, the air conditioning level of the air conditioner 3 can be variably controlled.

By the way, the human body detection sensor A and the illumination control system B are organically combined even at night. That is, as shown in FIG. 1, the lighting control system B incorporates various intimidating devices 13, a video camera 14, and the like in addition to the lighting fixture 2, for example, the human body detection sensor A.
When an intruder is detected at, the intruder is intimidated by using the intimidating device 13, the lighting device 2 is turned on, and the intruder is photographed by the video camera 14.

In this way, the human body detection system A as the crime prevention system can be used for control of other systems even during the daytime and can be effectively used. Moreover, by organically coupling the human body detection system A with other systems, it is possible to reduce the overall system cost. Furthermore, the monitoring result of the human body detection sensor 6 in the daytime is also used in the sign system E. The sign system E is used, for example, to display the usage status of a conference room or a reception room, and receives the human detection status of the human body detection sensor 6 in the conference room or the reception room as the usage status, and Display the usage status of the reception room.

By the way, in the case of the conventional crime prevention system, in order to identify and judge the human body detection condition of each sensor 1, the wiring between the control device 6 and each sensor 1 must be star wiring. Therefore, the workability was poor. However, in the case of this embodiment, the two-wire transmission line L
_{Since the} human body detection system is constructed by the time division transmission method using 1, the human body detection status of each sensor 1 can be identified and judged without using the star wiring, and the workability is improved.

The operation of the human body detection system A of this embodiment as a security system at night will be described below. The conventional crime prevention system had a high false alarm rate. Therefore, in this type of conventional security system, it has been attempted to reduce the false alarm rate by increasing the function of each sensor 1. However, there is a limit to improving the function of each sensor 1 in this way, and there is a problem that the cost increases.

In order to improve this point, in the case of this embodiment, the following method is used to reduce the false alarm rate as a crime prevention system. When this method is adopted, as described above, a plurality of sensors 1 are provided in a specific space, for example, in each room.
Need to be placed. Here, individual human body detection areas of the respective sensors 1 are shown by square areas in FIG. 7. Then, the room is further divided into a plurality of areas. That is, the area (shown by the diagonal line descending to the left in the drawing) facing the door 20 and the window 21 is the first warning area, and the area between them (shown by the diagonal line descending to the right in the drawing) is the second warning area. In addition, a region farther away from the door 20 and the window 21 (shown by a slanting line formed by a dash-dotted line in the figure in the figure) is a third warning region, and a region farthest from the door 20 and the window 21 (in the diagram The fourth warning area is defined by the diagonal line (dashed line consisting of the one-dot chain line descending to the right).

First, when the human body detection output is obtained on the route from the area A to the area C and the area B via the area B, it is determined that the human body detection output in this case is caused by the intruder. Further, when the human body detection output is continuously obtained a plurality of times by the same sensor 1 in each of the areas A to D, it is determined that the human body detection output is also caused by the intruder. Here, for example, if the human body detection output is obtained in the area C from the area A without passing through the area B, in this case, it is not immediately determined that the person is an intruder, and the operation of monitoring the human body detection state thereafter is performed. continue. By doing so, it is possible to comprehensively determine whether or not the person is an intruder based on the human body detection status by the plurality of sensors 1, and therefore the false alarm rate can be reduced even if the performance of each sensor 1 alone is not high.

In the case where area D in FIG. 7 is an area that requires special caution, it is determined that an intruder exists if human body detection output is obtained even once in this area D. By doing so, it is possible to prevent a false alarm in a particularly important warning area, which is preferable. By the way, as a method of transmitting the human body detection status in each of the above-mentioned warning areas A to D to the control device 6 of the human body detection system A, the following method is adopted. For example, if a return signal of a plurality of bits is sent during the return signal period of the above-mentioned transmission signal, the upper several bits of the above return signal are used as bits indicating the type of each sensor 1, and the lower several bits belong to itself. Areas I to II are indicated. For example, area a is "00",
Region b is "01", region c is "10", region d is "1"
1 ”, and when a human body is detected by each sensor 1, the monitoring data is returned to the control device 6 when accessed by the control device 6. When the human body is not detected, the monitoring data is not returned, or the monitoring data indicating that the human body is not detected is returned.
In the case described above, the control device 6 cyclically accesses each sensor 1 at night to perform continuous warning, but the sensor 1 that has obtained a human body detection output.
May send an interrupt request to the control device 6 and return the monitoring data.

In this way, it is not necessary for the control device 6 to store in which area each sensor 1 is installed, and the configuration and processing of the control device 6 can be simplified. Moreover, there is an advantage that the warning area to which each sensor 1 belongs and the type of the sensor 1 can be arbitrarily changed. By the way, it is preferable to use, for example, a pyroelectric sensor using a pyroelectric element (PIR) as the sensor 1 because the human body can be satisfactorily detected in its own human body detection region. In addition to the pyroelectric sensor, a sensor using light or ultrasonic waves may be used.

Here, as the optical sensor, for example, in order to detect a human body in a specific area, a sensor including a light projector and a light receiver, which generates a human body detection output when light from the light projector is blocked, is used. For detecting the door 20, the window 21, or the area near the wall, a device that emits light to or receives light from the wall and detects the light reception level or its change to generate a human body detection output may be used.

In the case of the above-mentioned optical sensor, so-called linear human body detection is performed, but in the case of using an ultrasonic sensor, for example, three-dimensional human body detection is performed almost as in the case of a pyroelectric sensor. It is possible. Further, in order to further reduce the false alarm rate, a composite sensor in which the above various sensors are combined may be used. Further, a magnetic sensor is installed on the door 20 or the window 21 to warn the opening / closing state of the door 20 or the window 1.
May be incorporated into the security system.

By the way, the human body detection status of the human body detection system A at night is sent to the central controller 11 in real time. When the human body detection system A detects an intruder, the central control device 11 receives the output via the control device 6 and outputs the output to the outside via the output device 12. In this case, for example, the output device 12 makes an external transfer via a dedicated telephone line or a public telephone line, or makes an emergency call to a security guarantee company. In addition, it is preferable to be able to report to the security guarantee company in this way because the number of personnel required for security can be reduced. Needless to say, intrusion of an intruder is also notified to the manager's office. further,
The video camera 14 as the above-described image capturing device and the central control device 11 are connected using an image transmission line, and the image captured by the video camera 11 when an intruder is detected is also transmitted to the outside together with the notification. It may be transmitted. By doing so, there is an advantage that it is possible to appropriately deal with the case where the intruder has a weapon or the like.

In the above case, the case where the intruder is detected from the intruding state has been described. However, this can be used in reverse (in some cases, the monitoring area is widened) to determine the route that the last exiter leaves. Is also possible. In the above-mentioned case, for example, the comprehensive monitoring control system in which the entire building is centrally monitored and controlled has been described. However, for example, the comprehensive monitoring control used when performing comprehensive monitoring control for each tenant like a tenant building. In the case of system,
As shown in FIG. 8, a control device 19 may be provided for each area in which each tenant has moved in, and the control device 19 may collectively monitor and control the terminals.

Further, the lighting fixture 2 and the air conditioner 3 whose operation is controlled according to the output of the sensor 1 during the daytime may be incorporated in the human body detection system A as shown in FIG. In addition, in the human body detection system in this comprehensive monitoring and control system, a light emitter 13a, a speaker 13b, and a video camera 14 as the intimidating device 13 for intimidating at night are also integrally incorporated, and the switching between day and night is for timekeeping. The timer 18 or the output of the key management system indicating that a specific key has been returned to the key box 4. Further, in this comprehensive supervisory control system, the transfer output system F is provided separately from the central control unit 11, and the transfer output can be sent to the central monitoring room.
