Description

Embodiments of the present invention relate to a control system and a sensor device.

Generally, a control system has a control device and one or more terminal devices, and the control device and one or more terminal devices are connected by a signal transmission path. The terminal device is a sensor device such as a motion sensor or a controlled device such as a lighting device. For example, the control device receives a status signal or the like from the sensor device or the like via the transmission path. The control device transmits a control signal to the controlled device via the transmission path based on the received status signal and the like.

The terminal device includes a terminal device that performs a predetermined operation based on the received control signal, and a terminal device that has a set value such as an operating condition and can change the set value. For example, when the terminal device is a sensor device, there is a device in which the setting value information is stored in a storage unit such as a memory of the sensor device and the setting value information can be changed.

The setting value can be changed by using a setting switch such as a DIP switch for setting the setting value provided in the terminal device, and control information for changing the setting value is emitted to the terminal device having an infrared receiving unit. There is a method of using an infrared remote controller, and the like.

However, when changing the set value, the setting work is not easy when the position or place where the terminal device is installed is a high position in a building such as a warehouse. For example, a complicated work is required to install a stand or the like for a worker to stand up and perform a setting switch switching work in a building so that the worker can work in a high place. Also, when using an infrared remote controller, there is a limit to the distance that the infrared signal can reach, and it is necessary to avoid interference depending on the environment for transmitting and receiving the signal, so search for the position or place where the infrared ray reaches, etc. It requires complicated work.

Further, it is possible to provide the control device with a function of changing the setting value of the terminal device. However, if the control device does not originally have such a function, the control device is configured to set the terminal device. It is necessary to add a value setting change function, for example, a software program, which is costly.

(Constitution)
FIG. 1 is a configuration diagram of a lighting control system according to the present embodiment. The control system 1 of the present embodiment is a lighting control system including a control device 2 and a plurality of lighting devices 3 which are terminal devices to be controlled. Each lighting device 3 is connected to the blinker 4 which is a terminal device by a signal line 4a. Each lighting device 3 performs an on/off operation according to a drive signal from the blinker 4 connected to the power supply 4b. The control device 2 and the blinker 4 are communicably connected to each other via a transmission line 5.

The control system 1 further includes a wall switch 6 and a motion sensor 7. The wall switch 6 and the motion sensor 7 are also connected to the transmission path 5. The wall switch 6, which is a terminal device, is attached to the wall of the living room and has a plurality of operation buttons (not shown). The user in the living room can operate each operation button to turn on/off the desired lighting device 3.
When the operation button is operated, the wall switch 6 transmits an operation signal corresponding to the operation on the operated operation button to the control device 2. The operation signal is transmitted from the wall switch 6 to the control device 2 via the transmission path 5. That is, the control system 1 includes the control device 2 and a plurality of terminal devices, which are connected to each other via the transmission path 5. The control device 2 can communicate with each terminal device. Here, communication cannot be performed between a plurality of terminal devices, and communication is performed only between the control device 2 and each terminal device.

The control device 2 transmits a control signal to one or more lighting devices 3 designated in the received operation signal to the blinker 4 via the transmission path 5. The blinker 4 has a plurality of relay circuits, and outputs an on or off drive signal to one or more designated lighting devices 3 based on the control signal.

The human sensor 7, which is a terminal device, is a sensor device that detects the presence or absence of a person based on infrared rays emitted by the person. The human sensor 7 has a storage device 22 (FIG. 3) that stores set values such as operating conditions. Here, the holding time TS is stored in the storage device 22 of the motion sensor 7 as the set value. When the human sensor 7 detects a change in the output signal of the infrared detector, that is, when a person is detected, the human sensor 7 transmits the set holding time TS and the detection signal to the control device 2 via the transmission path 5. That is, the holding time TS is the time during which the detection signal is continuously output after the change in the infrared ray is detected, or the detection signal output by the motion sensor is held. In other words, the holding time TS is control information, which is information about the operating condition of the motion sensor 7. Then, the control device 2 controls at least one of the plurality of lighting devices 3 based on the received detection signal.

For example, a plurality of lighting devices 3 are installed on the ceiling of the living room, and the user can operate the wall switch 6 to turn on or off the desired lighting device 3. Further, a human sensor 7 is installed on the ceiling of a predetermined area in the living room, and when the human sensor 7 detects that there is a person in the area, the control device 2 detects the presence of the person based on the received detection signal. When the illumination device 3 of the area is turned on and no one is present in the area, the illumination device 3 of the area is turned off.

A setting device 8 can be connected to the wall switch 6. The setting device 8 has a display device 8a and an operating device 8b. The operation device 8b includes a plurality of operation buttons. The cable 8c extends from the setting device 8. The cable 8c has a connector 8d that can be connected to the connector 6a of the wall switch 6 at the tip.
That is, the wall switch 6 is a switch device that is connected to the transmission path 5 and has the operation unit 8b as an operation unit for instructing at least one operation of the plurality of lighting devices 3. The setting device 8 as a terminal device can be connected to the wall switch 6 and can transmit a transmission message via the wall switch 6 as described later.

A person who manages the control system 1 can connect the setting device 8 to the wall switch 6 through the connector 8d to check the operation and setting contents of the wall switch 6 and communicate with the control device 2. In addition, here, the setting device 8 and the wall switch 6 are communicably connected by a cable 8c by wire, but may be communicatively connected by wireless using infrared rays or the like.

Note that, in FIG. 1, the control system 1 has one human sensor 7 for the sake of simplicity of description, but it may have a plurality of human sensors as shown by the dotted lines. Furthermore, the control system 1 may control a plurality of lighting devices 3 in a plurality of living rooms such as buildings, in which case the wall switch 6 and the human sensor 7 are arranged for each living room.

FIG. 2 is a block diagram showing the configuration of the setting device 8. The setting device 8 includes a processor 11, a storage device 12, and a communication interface 13, and further includes the above-described display device 8a and operation device 8b. Each of the display unit 8a and the operation unit 8b is connected to the processor 11 via an interface (not shown).

The processor 11 includes a central processing unit (CPU), and is capable of executing various programs stored in the storage device 12. The storage device 12 also stores a change program 12a for changing the set value of the motion sensor 7 described later. The processor 11 may be composed of an electronic circuit such as an FPGA (Field Programmable Gate Array).

The setter 8 can transmit data to the transmission line 5 and receive data from the transmission line 5 via a communication interface (hereinafter, abbreviated as communication I/F) 13 connected to the cable 8c. .. In accordance with various programs, various information is displayed on the display 8a, and screens for inputting various data are displayed.

FIG. 3 is a block diagram showing the configuration of the motion sensor 7. The human sensor 7 includes a processor 21, a storage device 22, a detection element 23, and a communication I/F 24. The detection element 23 is, for example, a pyroelectric sensor that detects infrared rays, and is connected to the processor 21 via an interface (not shown).

Like the processor 11, the processor 21 includes a central processing unit (CPU) and can execute various programs stored in the storage device 22. The storage device 22 has a storage area 22a for storing information on the retention time TS. The processor 21 may be configured by an electronic circuit such as an FPGA (Field Programmable Gate Array).

The human sensor 7 can transmit data to the transmission line 5 and receive data from the transmission line 5 via the communication I/F 24 connectable to the transmission line 5. The human sensor 7 detects a change in the infrared rays detected by the detection element 23, and when the amount of the detected infrared rays changes, a detection signal is transmitted via the transmission path 5 for a set holding time TS. It is transmitted to the control device 2. When there is no change in the detected amount of infrared rays, the human sensor 7 stops transmitting the detection signal when the holding time TS has elapsed from the last change in the amount of infrared rays.

FIG. 4 is a diagram showing an example of a display screen of the setting device 8 when changing the set value of the motion sensor 7. The screen shown in FIG. 4 is a set value change screen G displayed on the display screen of the display 8a of the setting device 8. The setting value change screen G has two input fields 31 and 32 for inputting the sensor number SN and the holding time TS.

The operator who operates the setting device 8 operates the operating device 8b to move the cursor to the input field 31, and operates the operating device 8b to set the sensor number SN of the motion sensor 7 whose setting value is to be changed. You can enter. Further, the operator operates the operation unit 8b to move the cursor to the input field 32, and inputs the changed holding time TS by operating the operation unit 8b. In the setting value change screen G of FIG. 4, the sensor number SN is “001” and the holding time TS is “5” (seconds). The sensor number SN is identification information of the terminal device used in the control system 1, and is, for example, an identification code (ID) or address data.

After inputting the sensor number SN and the holding time TS, the operator operates the operation device 8b via the wall switch 6 and transmits the input information of the sensor number SN and the holding time TS to the control device 2. You can

FIG. 5 is a flowchart showing an example of the flow of a process of changing the set value of the motion sensor 7. FIG. 5 is executed in the setter 8. When the operator of the setting device 8 operates the operating device 8b and inputs an instruction to execute the change processing program for changing the set value of the motion sensor 7 into the setting device 8, the processor 11 changes the set value of FIG. The processing program is read from the storage area 12a of the storage device 12 and executed.

The processor 11 generates a set value change screen G (FIG. 4) for changing the set value and displays it on the display 8a (step (hereinafter abbreviated as S) 1). The operator can operate the operation device 8b on the displayed setting value change screen G to input the information of the sensor number SN and the holding time TS.

Unless the operator operates the operation device 8b to instruct the transmission of the input information, the process returns to S1, and the operator inputs or changes the information of the sensor number SN and the holding time TS. be able to. When the operator operates the operation device 8b to input the transmission instruction of the input information to the setting device 8, the processor 11 transmits the input information of the sensor number SN and the holding time TS to the control device 2 ( S3), the process of changing the set value ends. That is, the setting device 8 as the terminal device holds the sensor number SN as the identification information of the human sensor 7 which is another terminal device and the setting value information as the control information for controlling the operation of the human sensor 7. The information of the time TS is included in the data part 43 in the transmission message and is output to the control device 2 via the transmission line 5.

FIG. 6 is a diagram showing a structure of a transmission message transmitted to the transmission line 5 by the processing of S3. The transmission message 41 is a message transmitted/received on the transmission path 5, and has a predetermined format. The transmission message 41 includes a source address, a destination address, a control command signal, and the like. Data can be transmitted and received among the control device 2, the blinker 4, the wall switch 6, and the motion sensor 7 by a transmission message in a predetermined format.

The transmission message 41 also includes a header part, a source address, etc., but in FIG. 6, only the destination address part 42 and the data part 43 are shown, and other data are not shown. In the transmission message 41, the destination address part 42 is a field containing information on the destination address (ADD) of the other party to which the transmission message 41 is sent. The data portion 43 is a field including the sensor number SN and the holding time TS information (DATA) input on the setting value change screen G.

For example, when a user presses an operation button of the wall switch 6 to turn on a certain lighting device 3, the wall switch 6 sends a transmission message including a command signal according to the user's operation to the control device 2. To do. In the transmission message 41 at that time, the destination address part 42 includes the address of the control device 2, and the data part 43 includes the command signal for turning on the lighting device 3 designated by the user. When the control device 2 receives the transmission message 41 addressed to itself, the control device 2 performs processing according to the command signal included in the data portion 43. In the above case, a command signal for turning on the lighting device 3 is generated and transmitted to the blinker 4.

As described above, the transmission message 41 on the transmission path 5 includes the destination address portion 42 including the destination address and the data portion 43 including the command signal and the like. Each device connected to the transmission path 5 can determine whether the transmission message 41 is a message addressed to itself based on the destination address. Each device executes a process based on the data included in the data section 43 when the received transmission message is a message addressed to itself. In other words, each device such as the blinker 4, the wall switch 6, and the human sensor 7 as well as the control device 2 ignores the transmission message 41 when the received transmission message is not a message addressed to itself, and Also, the process of is not executed.

Further, here, the format of the data section 43 is predetermined so that the motion sensor 7 can perform a predetermined operation based on the control information in the data section 43 of the transmission message 41, which will be described later. That is, in order to make the human sensor 7 change the set value, identification information for identifying the human sensor 7 (for example, the sensor number SN of the human sensor 7) is arranged at a predetermined position in the data section 43. The setting value information of the setting value to be changed is also arranged at another predetermined position in the data section 43.

Therefore, the motion sensor 7 determines the presence or absence of its own identification information (for example, the sensor number SN of the motion sensor 7) in the data portion 43 even when the received transmission message is not a message addressed to itself. be able to. Further, the human sensor 7 extracts the setting value information from the data section 43 when the data section 43 includes its own identification information even when the received transmission message is not a message addressed to itself. You can also do it.

Note that, here, when the setting value of the motion sensor 7 is changed, the destination address in the transmission message generated by the setter 8 is the address of the control device 2, but the transmission message includes one specific address. It may be in a format such as broadcast without specifying.

FIG. 7 is a flowchart showing an example of the flow of setting value change processing in the human sensor 7. As described above, when the human sensor 7 detects a person, the human sensor 7 transmits a detection signal to the control device 2 via the transmission path 5. However, the processing of FIG. 7 is different from the human detection processing. It is constantly executed during the operation of the sensor 7. Therefore, the processor 21 constantly monitors the transmission message transmitted on the transmission path 5.

The processor 21 determines whether the message received via the transmission path 5 is a transmission message addressed to itself (S11). The determination as to whether or not the transmission message is addressed to itself is made based on the destination address included in the transmission message. Depending on whether the destination address matches the address of the motion sensor 7, it is determined whether the transmission message is addressed to itself.

When the destination address matches the address of the motion sensor 7 (S11: YES), since the received message is a transmission message addressed to itself, the processor 21 executes processing according to the transmission message including the command ( S12), the process returns to S11.

When the destination address does not match the address of the human sensor 7 (S11: NO), the processor 21 determines whether the data portion 43 in the received transmission message includes its own sensor number SN (S13). That is, the process of S13 executed in the processor 21 constitutes a determination unit that monitors the transmission path 5 and determines whether or not the identification information of the self is included in the data portion 43 of the transmission message transmitted to the transmission path 5. To do.

As described above, when the setting device 8 transmits a transmission message for changing the setting value of the motion sensor 7 via the wall switch 6 to the control device 2 (S3), the destination address portion 42 of the transmission message 41 is transmitted to the control device 2. Since the address of the control device 2 is set, the transmission message 41 is transmitted from the setting device 8 to the control device 2 via the wall switch 6. The control device 2 receives the transmission message 41, but since it does not include an instruction to instruct execution of some processing by itself, the control device 2 does not execute anything.

However, in the human sensor 7, when it is determined that the data section 43 includes the sensor number SN of its own (S13: YES), the processor 21 sets the setting value included in the data section 43 to the storage area of the storage device 22. The operation of rewriting the information of the holding time TS stored in 22a is performed (S14). After S14, the process returns to S11. When it is determined that the data unit 43 does not include the sensor number SN of the user (S13: NO), the process returns to S11.
Therefore, in the processing of S11, S13, and S14, when the identification information of the self is included in the data section 43, the processing using the control information in the data section 43 is performed (S14), and the identification information of the self is identified as the data section. When it is not included in 43, a process execution unit that does not perform the process using the control information is configured.

As described above, the human sensor 7 as the terminal device monitors the transmission path 5, determines whether or not the identification information of itself is included in the data portion 43 of the transmission message transmitted to the transmission path 5, and If the identification information is included in the data part 43, the process using the control information in the data part 43 is performed. If the identification information of the self is not included in the data part 43 of the transmission message, the data part 43 is transmitted. The process using the control information in 43 is not performed.
Therefore, the setting value of the motion sensor 7 can be changed by inputting the sensor number SN and the setting value on the setting device 8 from a predetermined screen.

Therefore, according to the above-described embodiment, it is possible to transmit the control signal for controlling the operation of the terminal device without requiring the complicated work of the related art and without adding the function of the control device. A control system and a sensor device can be provided.

In particular, as in the above-described embodiment, the setter 8 can transmit the set value to the motion sensor 7 without directly communicating with the motion sensor 7, and as a result, the motion sensor 7 can The setting value of can be changed.

Therefore, for example, when a sensor device is added to the already installed transmission path, if the sensor device has the processing function of FIG. 7 described above, the setting value of the added sensor device is changed by the setter 8. be able to.

The control system 1 of the above-described embodiment is an illumination control system that uses the motion sensor 7 as a sensor device and changes the set value of the motion sensor 7. These types of sensor devices may be used. For example, when the sensor device is an illuminance sensor, information about the calibration value of the illuminance sensor can be similarly transmitted from the setter 8 to the illuminance sensor to change the set value. Furthermore, the set value of the blinker 4 as the terminal device may be similarly transmitted from the setter 8 to the blinker 4 to change the set value.

Furthermore, although the control system described above is a lighting control system, the embodiments described above can also be applied to a building air conditioning control system and other systems.

Further, in the above-described embodiment, the setting device 8 is connected to the wall switch 6, and the setting device 8 sends the transmission message via the wall switch 6. However, the wall switch 6 sets the settings of the setting device 8. It may have a value changing function. For example, the wall switch 6 has a function of transmitting a transmission message for changing the set value to the human sensor 7 as one function, and the wall switch 6 does not have the setter 8 as described above. It is also possible to be able to send a transmission message for changing various setting values.

Furthermore, in the above-described embodiment, the sensor device as the terminal device changes the setting value, but the terminal device may be caused to perform another operation. For example, if the terminal device is an added lighting device, the setting device 8 may turn on/off the lighting device.

These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
