As shown in FIG. 2, the information output apparatus 1 is equipped with the control part 10, the memory | storage part 15, the communication part 16, etc.

The communication unit 16 includes a communication interface for communicating via the transmission line L1 with the control unit 6 by wire. The communication unit 16 transmits output information to the control unit 6.

The storage unit 15 is composed of a device selected from Read Only Memory (ROM), Random Access Memory (RAM), or Electrically Erasable Programmable Read Only Memory (EEPROM). The storage unit 15 stores information of reference images, history information, setting information, and the like used in the image processing and conversion processing, etc. in the control unit 10.

The control unit 10 is configured of, for example, a microcontroller having a central processing unit (CPU) and a memory as main components. Then, the microcontroller functions as the control unit 10 by the CPU executing the program stored in the memory. The program executed by the CPU is pre-recorded in the memory of the microcontroller here, but may be provided by being recorded on a recording medium such as a memory card or may be provided through an electric communication line such as the Internet. The control unit 10 is configured to control the communication unit 16 and the like.

As shown in Fig. 2, the control unit 10 includes an acquisition unit 11, a conversion unit 12, an output unit 13, and a reception unit 14. In other words, the control unit 10 has a function as the acquisition unit 11, a function as the conversion unit 12, a function as the output unit 13, and a function as the reception unit 14.

The acquisition unit 11 acquires the detection result (image information here) regarding the environment space SP1 from the detection unit 3 as detection information. Hereinafter, the detection information may be simply referred to as an “image”.

The conversion unit 12 converts the image (detection information) into output information about the sun according to the purpose of the output destination OT1. In other words, the conversion unit 12 extracts information according to the use of the output destination OT1 from the image. Here, the conversion unit 12 converts it to output information by applying predetermined conditions based on the aspect. Predetermined conditions may include one or more for each use. The predetermined conditions are stored in advance in the storage unit 15 (or the memory of the control unit 10).

The predetermined conditions may include, for example, the following first to eighth conditions, but are not limited to these. The first condition is that a person has entered (or has left) the environment space SP1. The second condition is that a moving object such as a person is moving in the environment space SP1. The second condition may be a condition relating to the specification of the moving direction (vector) other than the presence or absence of a movement state such as a simple person, or a condition such that the activity amount of a person during work is a constant amount. The third condition is that a person has been in the environment space SP1 for a period of time or longer. The fourth condition is that the number of people in the environmental space SP1 is equal to or greater than a certain number. The fifth condition is that in the environment space SP1, if there are sections in which a plurality of people are concentrated, the degree of concentration (congestion) is equal to or greater than a certain frequency. The sixth condition is that the person who has entered the environmental space SP1 is a specific person (or an unsuspecting person) (individual identification). The seventh condition is that the illuminance (brightness) in the environment space SP1 is equal to or higher than a predetermined value. The eighth condition is that a person is located in a specific section in the environmental space SP1 (location information).

The above-described condition may be an inverse condition with respect to the threshold value, for example, a condition that the illuminance is less than a predetermined value may be set. In addition, the numerical values (number of people, congestion, roughness, etc.) under the above-described conditions may be an average value or an amount of change in addition to the instantaneous value.

In the actual use mode, it is preferable that any one or more of the first to eighth conditions and the like can be set in advance so as to be applied as a predetermined condition. For example, it is preferable that the manager can set the conditions corresponding to each use for the image sensor device 200 via the control unit 6 using the monitoring device 7. For example, the first condition and the seventh condition may correspond to the lighting control. As other uses, for example, for the air conditioning control, the first condition and the fourth condition may be supported. As another use, for example, the eighth condition may correspond to LPS (Local Positioning System) control. On the other hand, with respect to the predetermined conditions, other conditions other than the above-described first condition to eighth condition may be set further later. Separate conditions may be added, for example, by updating the software of the information output device 1.

Further, an operation unit such as a dip switch that accepts an operation related to setting the condition, or a reception unit that receives a signal related to setting the condition from a remote controller may be provided in the housing of the image sensor device 200.

That is, the conversion unit 12 determines an aspect according to the use of the output destination OT1 from a plurality of different types of aspects (for example, the above-described conditions), and converts the detection information into output information. In the present embodiment, the reception unit 14 accepts settings from the monitoring device 7, the operation unit, the reception unit, and the like, which conditions correspond to which application. In other words, the reception unit 14 accepts settings related to a correspondence between a plurality of types of aspects and a plurality of uses. The storage unit 15 stores the contents (correspondence relationship) of the settings received by the reception unit 14. The conversion unit 12 determines an aspect according to the use of the output destination OT1 based on the contents of the setting stored in the storage unit 15. Therefore, conversion to output information can be performed more appropriately for each application.

The conversion unit 12 has, as a basic function, an image processing function and a conversion processing function. For example, the conversion unit 12 may have a function of sequentially acquiring images captured from the detection unit 3 at predetermined time intervals (sampling intervals) through the acquisition unit 11. The conversion unit 12 may have a function of creating a difference image between successively acquired images. The conversion unit 12 may have a function of comparing the reference image stored in advance in the storage unit 15 with the image acquired from the detection unit 3. The reference image may be, for example, an image of the environment space SP1 captured in the absence of a person, or an image of the environment space SP1 in a predetermined illumination environment state.

The conversion unit 12 creates a binarized image obtained by binarizing the differential image based on the sensitivity value set for the environment space SP1 and the differential image. And a function for determining location information and the like. The sensitivity value is a threshold (background difference threshold) that becomes a reference when binarizing the difference image. The binarized image is composed of, for example, white pixel values and black pixel values. The conversion unit 12 makes the pixel of the pixel value white when the pixel value of the pixel in the acquired image is greater than or equal to the background difference threshold, and the pixel of the pixel value when the pixel value is less than the background difference threshold. Make it black. An image area in a plan view viewed from the ceiling side of the environment space SP1 is divided into a plurality of sections (for example, one section is 8x8 pixels), and each of the plurality of sections is covered. The binarized image of the environment space SP1 may be created by comparing the average value of the pixels included in the partition and the background difference threshold.

In addition, the conversion unit 12 has a function of determining whether a person in the environment space SP1 is a specific person (for example, an employee) registered in advance, based on the face image of the person shown in the acquired image. May be The conversion unit 12 searches a group of information for reference (a plurality of face images) previously stored in the storage unit 15, and if there is a face image judged to correspond to a person in the acquired image, the face image Information including the corresponding personal name, affiliation name, and the like may be generated. The information group for reference may be regularly updated from the monitoring device 7 or the management server 8.

These functions of the above-described conversion section 12 can be performed according to predetermined conditions that are set in advance.

From the acquired image information, the conversion unit 12 is, for example, "the person has entered (departed) to the conference room", "the number of people in the conference room is 5 or more", and "to a specific section (location) of the conference room" Information such as "There is a person" and "Employee A is in the meeting room" is converted into output information including one or more. That is, the output information includes the result of the determination regarding the predetermined condition. The output information is output from the output unit 13 to the control unit 6 via the communication unit 16, converted into actual control commands (control information) in the control unit 6, and then output to OT1. It is transmitted to the lighting device 4.

In the present embodiment, data corresponding to the determination result in the output information and the control information is registered in advance in the storage unit of the control unit 6 for each use. When the use is lighting control, for example, the determination result of "the person has entered the meeting room" is the control result for lighting (on) the lighting device 4, and the determination result of "the person has left the meeting room" is The control information for turning off (off) the lighting device 4 corresponds to each. In addition, the determination result of "there is a person in a specific section of the conference room" corresponds to control information that turns on only the lighting device 4 located in the section. On the other hand, if the use is air-conditioning control, the determination result of "the person has entered or left the conference room" corresponds to control information that turns on / off air conditioning of the air conditioning device.

The control unit 6 identifies the image sensor device 200 that is the source of the output information, and controls the lighting device 4 in the environment space SP1 in which the image sensor device 200 is installed. A control signal containing information is transmitted.

(2.3) Operation description

Hereinafter, the operation of the management system 500 will be described with reference to the flowchart of FIG. 3. On the other hand, the usage form is an example, and assumes that the use is only lighting control.

For example, it is assumed that employee A has entered a conference room which is one of the plurality of environmental spaces SP1 (step ST1).

The image sensor device 200 executes image processing and conversion processing, and "from the captured image (image information)", "people entered the conference room" and "illuminance is less than a predetermined value according to the purpose of lighting control. It is converted into output information including information "(step ST2). The image sensor device 200 sends output information to the control unit 6.

The control unit 6 uses a control signal for turning on the lighting device 4 based on the output information (room information and illuminance information) received from the image sensor device 200, and the lighting device 4 in the conference room. It transmits to the transmission adapter 5 under control. As a result, the control signal is transmitted to the lighting device 4 of the whole conference room via the transmission adapter 5, and the lighting device 4 of the whole conference room lights up (step ST3). On the other hand, if the illuminance is higher than a predetermined value during the day or the like, the control unit 6 may keep the lighting device 4 in the conference room in an unlit state, even if there is a person's presence, for example, and only some lighting devices 4 You may turn it on (lighting off).

Subsequently, it is said that employee A sits on a chair or the like after entering the room, and is in a system in a certain section (step ST4).

The image sensor device 200 continuously converts the captured image (image information) into output information including information such as "People are set up in a certain section of the conference room" (step ST5), and the control unit 6 ).

On the basis of the received output information (compartment information in the system), the control unit 6 maintains lighting of only 100% of the dimming rate, for example, only the lighting devices 4 of the corresponding section, and the other surrounding sections. A control signal may be transmitted so that the lighting device 4 is turned on at a dimming rate of about 50% (step ST6). On the other hand, when the output information includes information (movement information) that a person is on the move, the control unit 6 may transmit a control signal so that the lighting device 4 lights up at a dimming rate of about 30%.

After that, it is assumed that employee A has left the meeting room (step ST7).

The image sensor device 200 converts the captured image (image information) into output information including information "a person has left the conference room" (step ST8), and sends it to the control unit 6.

The control unit 6 transmits, for example, a control signal for turning off all the lighting devices 4 in the conference room based on the received output information (departure information) (step ST9).

As described above, in the image sensor device 200 of the present embodiment, the conversion unit 12 converts the detection information into output information about the sun according to the use of the output destination OT1. Therefore, it is possible to suppress the increase in the number of detection results to be acquired while making it applicable to a wider variety of uses. In particular, an increase in the number of detection results acquired by the image sensor device 200 is suppressed, so that an increase in the number of sensor devices installed on the ceiling surface of the detection unit 3 or the like can also be suppressed. Therefore, the possibility that the outstanding appearance (aesthetics) of the environmental space SP1 is damaged can also be reduced.

When the management system 500 includes an air conditioning control system, the image sensor device 200 displays image information from the detection unit 3, and "the number of people in the conference room is 5 or more" (person count information). It may be converted into output information to be included and transmitted to the control unit of the air conditioning control system. The control unit of the air conditioning control system may transmit, to the air conditioning equipment of the conference room, a control signal for reducing the temperature of the air conditioning equipment of the conference room by, for example, 1 ° C from the received output information. In addition, when the output information includes "a person's activity amount is equal to or greater than a certain amount" (activity amount information), the control unit of the air conditioning control system lowers the temperature of the air conditioning equipment in the conference room, for example, by 1 ° C from the received output information. The control signal for this may be transmitted to the air conditioning equipment of the conference room.

When the management system 500 includes a security system, the image sensor device 200 outputs image information from the detection unit 3, and includes "employee A is in the conference room" (individual specific information). It may be converted into information and transmitted to the control unit of the security system. The control unit of the security system transmits, to the monitoring device, the purpose of not being unsuspecting from the received output information. If the specific information indicates that the corresponding employee information does not exist, that is, the probability of the unsuspecting is high, the control unit of the security system transmits the effect to the monitoring device. As a result, the safety of the office building is secured.

The information output device 1 can also be shared between various systems at the same time. For example, when the management system 500 includes both the lighting control system and the air conditioning control system, the image sensor device 200 receives image information from the detection unit 3, "a person entered the conference room." May be converted into output information including room information, and transmitted to their control unit. In this case, these control units may transmit on control signals of the lighting device 4 and the air conditioning device, respectively.

Regarding control units such as an air conditioning control system, a security system, an LPS control system, and an integrated management system, the control units 6 of the basic example may be common, or one or more different control units may be provided in each system. That is, the image sensor device 200 may transmit output information to the control unit 6, and may distribute and transmit control signals to the lighting device 4 and the air conditioning device from the control unit 6 side, and transmit the image information. The 200 may distribute the output information for each use and transmit it to the target control unit. Also for the monitoring device 7 of the basic example, the administrator may intensively monitor a plurality of systems by using one monitoring device 7, or even if one or more different monitoring devices are provided in each system. do.

By the way, it is preferable that the image sensor device 200 has an operation mode selection function for selecting what application it is used for. The operation mode is a lighting control mode, an air conditioning control mode, a security mode, and the like. The manager may be able to select a mode by operating the operating unit such as a plurality of switches in the housing of the image sensor device 200 or by setting from the monitoring device 7. When the reception unit 14 receives, for example, a switch operation from the lighting control mode to the air conditioning control mode, the conversion unit 12 receives the air conditioning control from the first condition and the seventh condition applied in the lighting control. Switch to the first and fourth conditions that apply. It is also possible to select both the lighting control mode and the air conditioning control mode at the same time. In this case, the conversion unit 12 applies the first condition, the fourth condition, and the seventh condition.

(3.2) Modification 2 (Generation of control information)

In the basic example, the output information of the information output device 1 includes room entering / exiting information, number of people information, personal specific information, and activity amount information, and does not include direct device control information. Then, the control unit 6 generates control information for instructing the control according to the sun to the device as the output destination OT1.

However, the information output device 1 may also generate control information for instructing control according to the sun with respect to the device that is the output destination OT1. That is, the output information of the information output device 1 may include control information. In this case, it is possible to cope with a case where the configuration for generating control information is not outside the information output device 1. For example, even if the control unit 6 is not provided, the information output device 1 directly transmits output information to the lighting device 4, and the lighting device 4 can be turned on and off.

Whether the conversion section 12 of the information output device 1 only converts information to and from the room-to-exit information, the number of persons, personal identification information, and activity amount information, or even to control information, the installation site It is desirable to be able to change from. Specifically, similarly to the operation mode selection function of the modified example 1, it is preferable that it can be changed by setting from the operation unit such as a switch in the housing of the image sensor device 200 or the monitoring device 7.

In particular, it is preferable that the control information is different information depending on the type of device. Even if there are a plurality of types of devices as the output destination OT1 (lighting device 4, air conditioning device, etc.), control information according to each type can be output.

On the other hand, when the information output device 1 converts to control information as in the present modification, even if it is the same information as "entered (departed)", the generated control command (control information) is used or the environment space SP1. Depends on. For example, the information of "entered (exited)" is converted to a command for controlling the lighting of the lighting device for lighting purposes, but can be converted to a command for notifying the invasion of a person for security purposes.

(3.3) Other modifications

In the basic example, the purpose of the output destination OT1 is only lighting control. On the other hand, when there are a plurality of uses, the output unit 13 of the information output device 1 may output the output information in different communication media according to the use of the output destination OT1. For example, output information may be transmitted by wired communication in lighting applications or wireless communication in air conditioning applications. In other words, the communication unit 16 may have a plurality of types of communication interfaces.

Alternatively, the output unit 13 of the information output device 1 may output output information in different communication standards according to the purpose of the output destination OT1. For example, output information may be transmitted by Wi-Fi (registered trademark) in lighting applications or by specific small-power radios in air conditioning applications.

In the basic example, the control unit 6 generates control information for instructing the control of the device as the output destination OT1, but some or all of the functions may be performed by the management server 8.

With regard to "individual identification (information)" in the basic example and the modification example 1, the output unit 13 of the information output device 1 does not include personal information and an aspect of output including personal information. The aspects of the output may be distinguished and output respectively. For example, according to each application, the output detail level for personal information is specified, such as the first level that is limited to the number of people, the second level that is limited to the name of the division, the third level that outputs image information, and the personal name. It may be possible to appropriately select and set from the fourth level to be output. In this example, the first level is an aspect of output that does not contain personal information, and the second to fourth levels correspond to an aspect of output that includes personal information. Specifically, the output unit 13 outputs image information (third level) for specifying an unsuspecting person, for example, for security purposes, while information that cannot identify an individual for lighting control purposes (several people in this room) You may output information about the level of human presence: first level).

In the basic example, the detection unit 3 is an imaging unit, and the detection information is image information, but is not particularly limited. For example, the detection unit 3 is a sound collection unit such as a microphone, and the detection information may be sound information. The information output device 1 may convert sound information (voice, footsteps, door opening / closing sounds, etc.) into output information including information such as a person's room, number of people, or location.

In the basic example, the information output device 1 has only one input destination, so that only image information, that is, only one type of input information is acquired and converted into output information. However, the information output device 1 may acquire two or more types of input information from a plurality of input destinations and convert them into output information. For example, the information output device 1, in addition to the image information from the detection unit 3, from the detection unit (sensor) different from the detection unit 3, the above-described sound information, temperature and humidity information, illuminance information, and CO _You may acquire at least one of the substance concentration information in the atmosphere, such as ₂ , and convert it into output information. The illuminance information may include illuminance measured by actually receiving light with a light receiving element of the first sensor device 301, not illuminance obtained by image processing. The output information may include, for example, two pieces of information such as "there was a room" obtained from the image information and "the concentration of CO ₂ is greater than or equal to a certain value" obtained from the substance concentration information. The control unit 6 may control the air conditioning equipment (for example, a ventilation fan) of the conference room to perform ventilation based on the received output information.

In the basic example, the information output device 1 converts to output information using the entirety of one image area. However, depending on the application, it may be converted into output information by using different division areas among one common image area. For example, even if it is the same single image, you may convert it into output information using the right half division area for lighting use, and the left half division area for air conditioning use, respectively.
