Description

Illumination condition transmission apparatus, illumination condition transmission method, illumination control system, program, and recording medium

The present invention relates to an illumination condition transmission device, an illumination condition transmission method, an illumination control system, a program, and a recording medium for controlling illumination to a device capable of automatic operation.

Usually, in facilities (for example, factories) that perform production activities using large-scale processing devices or the like, power is consumed at a rate illustrated in FIG. FIG. 7 is a pie chart showing an example of the ratio of power consumption in a production activity facility such as a general factory. As shown in this figure, among the entire power consumption, the power consumption due to the production power accompanying the operation of the processing apparatus for performing the production activity is the largest. On the other hand, the power consumption by lighting in the factory accounts for a relatively large proportion.

Conventionally, in order to reduce power consumption by such lighting, (1) unnecessary lighting is frequently turned off manually, (2) lighting such as fluorescent lamps is reduced to the minimum necessary, or (3) consumption A method such as investing in LED lighting with low power is adopted. However, with the recent increase in recognition regarding carbon dioxide reduction, it is required to reduce more power consumption than the power consumption reduced by these conventional methods. As a result, there has been a demand for a control system that automatically extracts unnecessary lights and turns them off to minimize power consumption.

An example of a method corresponding to such a request is proposed in Patent Document 1 and Patent Document 2. Specifically, these documents disclose an invention in which a motion of a person in a facility is detected using a human sensor, and lighting is turned on or off in accordance with the motion. However, in these inventions, when there is little movement of people or when the number of lights to be controlled is large, the lights are turned off even when necessary or turned on even when unnecessary. There are many malfunctions and problems. Furthermore, when a large number of human sensors are arranged in a range where a person moves, there is a problem that the control program becomes complicated.

On the other hand, techniques that can avoid these problems have also been proposed. For example, Patent Document 3 discloses a method of confirming an individual ID using an IC tag and controlling illumination according to an individual operation pattern. Furthermore, Patent Document 4 discloses a demand control method for forcibly controlling lighting when the power consumption of the entire factory exceeds a threshold value.

Japanese Patent Publication “Japanese Patent Laid-Open No. 2000-58273 (published on February 25, 2000)” Japanese Patent Publication “JP 2009-266605 A (published on November 12, 2009)” Japanese Patent Publication “Japanese Patent Laid-Open No. 2010-151341 (published July 8, 2010)” Japanese Patent Publication “Japanese Unexamined Patent Publication No. 2009-240054 (published on Oct. 15, 2009)”

However, the conventional technology as described above has a problem in that inappropriate lighting control is performed on the device because the state of the device in the factory is not taken into consideration. For example, there is a case where the lighting is turned off because the power consumption of the entire factory exceeds a threshold value, although the apparatus needs to illuminate with a certain amount of light.

Embodiment 1
A first embodiment according to the present invention will be described below with reference to FIGS.

(Production line 50)
First, the configuration of the production line 50 and the illumination control system 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram showing a configuration of the production line 50 according to the first embodiment of the present invention and a configuration of the illumination control system 100 according to the first embodiment of the present invention.

As shown in FIG. 2, in the production line 50, a press processing apparatus 2a, an integral molding apparatus 2b, a terminal processing apparatus 2c, and a quality inspection apparatus 2d are arranged in this order. The production line 50 is a production facility for continuously arranging various general automatic-operable production apparatuses for producing a predetermined product at a production site such as a factory. In this embodiment, the press working apparatus 2a presses metal parts such as terminals necessary for a product. The integral molding apparatus 2b integrally molds the terminal and a resin material that constitutes the housing of the product into the product. The terminal processing apparatus 2c processes a product terminal. The quality inspection apparatus 2d inspects the quality of products and aligns the products.

In the production line 50, the press processing device 2a, the integral molding device 2b, the terminal processing device 2c, and the quality inspection device 2d are all types of devices that can be automatically operated. That is, these devices are involved in the automatic production of products by, for example, automatic operation in an unattended environment at midnight.

The production line 50 is very large because it includes these four production devices. Since one lighting device cannot illuminate the entire production line 50, there are a plurality of lighting devices 6a to 6f in the factory having the production line 50. All of the illumination devices 6a to 6f are arranged on the upper part of the production line 50, that is, the ceiling of the factory, and illuminate the corresponding production device from above.

In this embodiment, as shown in FIG. 2, the illumination devices 6a to 6c are provided at positions where the press working device 2a can be illuminated. The illuminating device 6d is provided at a position where the integral molding device 2b can be illuminated. The lighting device 6e is provided at a position where the terminal processing device 2c can be illuminated. The illuminating device 6f is provided at a position where the quality inspection device 2d can be illuminated.

(Lighting control system 100)
In the present embodiment, the illumination control system 100 controls illumination of the illumination devices 6 a to 6 f in the production line 50. As shown in FIG. 2, the illumination control system 100 includes illumination condition transmission devices 1a to 1d and illumination control devices 4a to 4f.

The illumination condition transmission devices 1a to 1d are individually provided in the press processing device 2a, the integral molding device 2b, the terminal processing device 2c, and the quality inspection device 2d, respectively. That is, the illumination condition transmitters 1a to 1d are incorporated in the manufacturing apparatus as components of the corresponding manufacturing apparatuses. As will be described in detail later, each of the lighting condition transmission devices 1a to 1d determines the operating status of the corresponding manufacturing apparatus, and transmits a predetermined lighting condition based on the result to at least one of the corresponding lighting control devices.

Note that the illumination condition transmitters 1a to 1d are not necessarily provided in the corresponding manufacturing apparatus. For example, the illumination condition transmitting devices 1a to 1d may be arranged in any form in the factory where the press working device 2a and the like exist so as to be connected to the corresponding manufacturing apparatus.

The illumination control devices 4a to 4f are individually provided in the illumination devices 6a to 6f, respectively. As will be described in detail later, the illumination control devices 4a to 4f individually control the illumination of any of the corresponding illumination devices based on the illumination conditions received from the corresponding illumination condition transmission device.

(Lighting condition transmitter 1a)
The configuration of the illumination condition transmitting device 1a and the illumination control devices 4a to 4c constituting the illumination control system 100 will be described below with reference to FIG. FIG. 1 is a block diagram showing the configuration of the illumination condition transmitter 1a and the configurations of the illumination controllers 4a to 4c constituting the illumination control system 100 according to an embodiment of the present invention.

As shown in FIG. 1, the illumination condition transmitter includes a power meter 10a, a sensor 11a, an operating state determination unit 12a (determination unit), an illumination condition acquisition unit 13a (acquisition unit), and a transmission unit 14a (transmission unit). ing. Although not described in detail, the illumination condition transmitters 1b to 1d are also provided with the same members as the members included in the illumination condition transmitter 1a. In the present specification, each member included in each of the illumination condition transmitters 1a to 1d is distinguished by the difference in alphabets constituting the member numbers assigned to the members. For example, the illumination condition transmitter 1c includes an operating state determination unit 12c and an illumination condition acquisition unit 13c.

Hereinafter, the function of each member provided in the illumination condition transmitter 1a will be briefly described. The wattmeter 10a measures the power consumption of the press working apparatus 2a. The sensor 11a detects the state of the operating location of the press working apparatus 2a. The sensor 11a is mounted as a position sensor or an image sensor, for example.

The operating state determination unit 12a determines the operating state of the press working apparatus 2a based on the measurement result of the wattmeter 10a or the detection result of the sensor 11a. The illumination condition acquisition unit 13a acquires an illumination condition corresponding to the determined operation state from a memory (not shown) provided in the press working apparatus 2a.

In the present embodiment, the types of operating states determined by the operating state determination unit 12a include operating, standby, stopping, start-up adjustment, setup change, and repair. For each of the different operating states that can be taken by these press working apparatuses 2a, the corresponding illumination conditions are stored in advance in the memory in association with the corresponding operating states. Each illumination condition is information that defines the control content of illumination. In the present embodiment, the illumination condition stipulates illumination illuminance (dimming) or illumination on / off designation.

The specific contents of the lighting conditions are defined in advance for each manufacturing apparatus and each operating state depending on the type of the corresponding manufacturing apparatus and the corresponding operating state. For example, an illumination condition of “illumination on” is defined for an operation state of “stopped”. Even in the same operating state, illumination conditions may differ depending on the type of manufacturing apparatus. For example, in a manufacturing device that does not require any lighting for monitoring by workers during unattended automatic operation, such as the quality inspection device 2d, “lighting off” corresponds to the operating state of “in operation” To do. On the other hand, in a manufacturing apparatus that requires a certain amount of illumination for monitoring by an operator during unattended automatic operation, such as the integral molding apparatus 2b, the “in operation” operating state is not “illumination off”. "Dimming (for example, illumination with light of 10% of the maximum value)" corresponds.

The transmission unit 14a transmits the illumination condition given from the illumination condition acquisition unit 13a to a predetermined transmission range 60a defined in advance in the illumination condition transmission device 1a. In the present embodiment, the transmission unit 14a is implemented as a wireless communication device, and outputs the illumination condition as a wireless signal to the transmission range 60a. The transmission range 60a is a communication range in which a radio signal transmitted from the transmission unit 14a is transmitted. The transmission range 60a can be defined in advance in a desired range by adjusting the communication frequency or waveform of the radio signal or the shape of the communication antenna of the radio communication device.

Since the illumination control system 100 transmits the illumination condition as a wireless signal, it is not necessary to separately provide a complicated wire for transmitting the illumination condition to the ceiling. In addition, it is not necessary that only the lighting device corresponding to a specific manufacturing apparatus is provided in a separate system from other lighting devices. Therefore, the configuration of the illumination control system 100 can be further simplified, and the cost for mounting the illumination control system 100 can be further reduced.

As shown in FIG. 2, the illumination condition transmitting device 1a is provided at the tallest position in the press working device 2a. Although not clearly shown, among the members constituting the illumination condition transmitter 1a, the transmitter 14a is arranged at a position closest to the ceiling in the press working device 2a. Thereby, it is possible to minimize the possibility that the wireless signal (illumination condition) transmitted from the transmission unit 14a is subject to communication failure depending on the state of the illumination condition transmission apparatus 1a or another manufacturing apparatus. Although not described in detail, the same applies to the illumination condition transmitters 1b to 1d.

(Lighting control devices 4a to 4c)
As shown in FIG. 1, the illumination control device 4a includes a reception unit 41a (reception unit) and an illumination control unit 42a (control unit). The illumination control device 4b includes a reception unit 41b (reception unit) and an illumination control unit 42b (control unit). The illumination control device 4c includes a reception unit 41c (reception unit) and an illumination control unit 42c (control unit). Although not described in detail, the illumination control devices 4d to 4f also include the same members as the illumination control device 4a and the like. In the present specification, each member included in each of the lighting control devices 4a to 4f is distinguished by a difference in alphabets constituting a member number assigned to the member. For example, the illumination control device 4f includes a reception unit 41f and an illumination control unit 42f.

Hereinafter, functions of each member included in the illumination control device 4a will be briefly described. The receiving unit 41a receives the illumination condition transmitted from the illumination condition transmitting device 1a. The illumination control unit 42a controls illumination in the illumination device 6a based on the received illumination condition.

(Transmission range 60a-60d)
In the present embodiment, each of the illumination control devices 4a to 4c individually controls the illumination of the illumination devices 6a to 6c based on the illumination condition transmitted from the illumination condition transmission device 1a. Moreover, the illumination control device 4d controls the illumination of the illumination device 6d based on the illumination condition transmitted from the illumination condition transmission device 1b. The illumination control device 4e controls the illumination of the illumination device 6e based on the illumination condition transmitted from the illumination condition transmission device 1c. Further, the illumination control device 4f controls the illumination of the illumination device 6f based on the illumination condition transmitted from the illumination condition transmission device 1d.

Such precise individual control of illumination is realized by the transmission ranges 60a to 60d defined in each of the illumination condition transmitters 1a to 1d. As shown in FIG. 2, the illumination control devices 4a to 4c exist within the transmission range 60a. On the other hand, the illumination control devices 4d to 4f do not exist within the transmission range 60a. Therefore, the illumination condition transmitted from the illumination condition transmitter 1a reaches only some of the illumination controllers 4a to 4c among all the illumination controllers 4a to 4f. Thereby, the illumination condition transmitting device 1a, based on the determination result of the operating state in the press working device 2a, emits only the illumination devices 6a to 6c corresponding to the illumination condition transmitting device 1a among all the illumination devices 6a to 6f. It can be controlled through the illumination control devices 4a to 4c. Therefore, for example, when the press working apparatus 2a is stopped, the lighting devices 6d to 6f that cannot illuminate the press working apparatus 2a are not turned on, so that an unnecessary increase in power consumption in the factory can be prevented. .

Similarly, the illumination condition transmitter 1b provided in the integral molding apparatus 2b transmits the illumination condition only to the transmission range 60b. As a result, the illumination condition reaches the illumination control device 4d existing in the transmission range 60b, but does not reach the other illumination control devices. Therefore, it is possible to control the illumination of only the illumination device 6d that can illuminate the integrally molded device 2b.

Moreover, the illumination condition transmitter 1c provided in the terminal processing device 2c transmits the illumination condition only to the transmission range 60c. As a result, the illumination condition reaches the illumination control device 4e existing in the transmission range 60c, but does not reach the other illumination control devices. Therefore, it is possible to control the illumination of only the illumination device 6e that can illuminate the terminal processing device 2c.

Moreover, the illumination condition transmitter 1d provided in the quality inspection apparatus 2d transmits the illumination condition only to the transmission range 60d. As a result, the illumination condition reaches the illumination control device 4f existing in the transmission range 60d, but does not reach the other illumination control devices. Therefore, it is possible to control only the illumination device 6f that can illuminate the quality inspection device 2d.

As described above, in the present embodiment, the relationship between each manufacturing apparatus such as the illumination condition transmitting apparatus 1a in the manufacturing line 50 and the individually controlled lighting apparatus is the transmission range in each of the illumination condition transmitting apparatuses 1a to 1d. 60a to 60d are defined in advance. Therefore, for example, after moving the press processing apparatus 2a to another place, there is no need to reselect and reset the illumination device controlled corresponding to the press processing apparatus 2a. This is because a lighting device newly corresponding to the press working device 2a is automatically set by the transmission range 60a defined in advance in the lighting condition transmitting device 1a provided in the press working device 2a.

(Details of operating status judgment based on power consumption)
As described above, the operating state determination unit 12a can determine the operating state of the press working apparatus 2a based on the output from the sensor 11a. In this case, the sensor 11a needs to directly detect the operating state in the press working apparatus 2a, such as whether a metal part (workpiece or the like) is being conveyed in the press working apparatus 2a, or the press mold is moving up and down. is there. For this purpose, it is necessary to provide a large number of sensors 11a as position sensors in the press working apparatus 2a in order to determine in which position the workpiece or mold exists in the press working apparatus 2a. In addition, it may be difficult to accurately distinguish the operating state such as when the press working apparatus 2a is operating or stopped.

Therefore, it is preferable that the operating state determination unit 12a determines the operating state of the press working apparatus 2a based on the measurement result of the power consumption by the wattmeter 10a rather than the detection result by the sensor 11a. This is because the wattmeter 10a does not need to be provided in the press working apparatus 2a, unlike the position sensor. Moreover, it is because the operation state determination part 12a can determine the operation state of the press work apparatus 2a more easily and correctly based on the measurement result of power consumption.

Details of the determination of the illumination condition based on the measurement result of the power consumption will be described below with reference to FIG. FIG. 3 is a diagram illustrating a temporal change in power consumption in each manufacturing apparatus such as the press working apparatus 2 a arranged in the manufacturing line 50.

A graph 70a in FIG. 3 shows a temporal change in power consumption in the press working apparatus 2a. The vertical axis represents power consumption, and the horizontal axis represents time. In the period 71a, the power consumption is equal to or greater than the threshold value 80. Therefore, the operating state determination unit 12a determines that the press working apparatus 2a is operating in the period 71a. In the period 72a, the power consumption is below the threshold value 80. However, since a certain amount of power is consumed for control or the like, the power consumption is a certain amount greater than zero. Thereby, the operating state determination unit 12a determines that the press working apparatus 2a is on standby in the period 72a. In the period 73a, the power consumption is below the threshold value 80 and is nearly zero. Thereby, the operating state determination unit 12a determines that the press working apparatus 2a is stopped in the period 73a.

The graph 70b in FIG. 3 shows the time change of the power consumption in the integral molding apparatus 2b. The vertical axis represents power consumption, and the horizontal axis represents time. In the period 71b, the power consumption increases stepwise. The operating state determination unit 12b determines that the integral molding device 2b is being adjusted for startup in the period 71b based on the temporal change in power consumption in the period 71b. Normally, it is not possible to determine whether or not the integral molding apparatus 2b is being adjusted for startup based only on the power consumption value at a certain point in time. The operating state determination unit 12b can determine the operating state more accurately by determining the operating state based on a temporal change in power consumption.

In the period 72b, the power consumption is equal to or greater than a threshold (not shown). Therefore, the operating state determination unit 12b determines that the integral molding apparatus 2b is operating in the period 72b. In the period 73b, the power consumption is below a threshold value (not shown) and is nearly zero. Thereby, the operating state determination part 12b determines with the integral molding apparatus 2b being stopped in the period 73b.

The graph 70c in FIG. 3 shows the time change of the power consumption in the terminal processing apparatus 2c. The vertical axis represents power consumption, and the horizontal axis represents time. In the period 71c, the power consumption is below a threshold value (not shown) and is nearly zero. Thereby, the operating state determination part 12c determines with the terminal processing apparatus 2c being stopped in the period 71c. In the period 72c, the power consumption is equal to or greater than a threshold (not shown). Therefore, the operating state determination unit 12c determines that the terminal processing apparatus 2c is operating in the period 72c.

A graph 70d in FIG. 3 shows a temporal change in power consumption in the quality inspection apparatus 2d. The vertical axis represents power consumption, and the horizontal axis represents time. In the period 71d, the power consumption is below a threshold value (not shown) and is nearly zero. Thereby, the operation state determination unit 12d determines that the quality inspection apparatus 2d is stopped in the period 71d. In the period 72d, the power consumption is equal to or greater than a threshold (not shown). Therefore, the operating state determination unit 12d determines that the quality inspection device 2d is operating in the period 72d.

(Flow of lighting control processing)
The flow of the illumination control process in this embodiment will be described below with reference to FIGS. FIG. 4 is a flowchart showing a flow of illumination control processing in the illumination control system 100 according to the first embodiment of the present invention. Hereinafter, the illumination control by the illumination condition transmission device 1a and the illumination control devices 4a to 4c will be described as an example.

At night, in the production line 50, the press working apparatus 2a is automatically operated unattended. While the press working apparatus 2a is in operation, the wattmeter 10a measures the power consumption of the press working apparatus 2a (step S1) and outputs it to the operating state determination unit 12a. The operating state determination unit 12a determines whether or not the measured power consumption is less than a predetermined threshold (step S2). When the result of the determination in step S is “false” (No), the processing shown in FIG. 4 returns to step S1.

On the other hand, when the result of the determination in step S2 is “true” (Yes), the operating state determination unit 12a determines that the operating state of the press working apparatus 2a is stopped (step S3). Here, it is assumed that the power consumption of the press working apparatus 2a is almost zero. Based on the determination result, the illumination condition acquisition unit 13a acquires the illumination condition corresponding to the stop state from a memory (not shown) (step S4), and outputs it to the transmission unit 14a. This illumination condition defines that the illumination is turned on. As shown in FIG. 2, the transmission unit 14a transmits the input illumination condition to the transmission range 60a (step S5). As a result, the transmitted lighting conditions reach the lighting control devices 4a to 4c.

The reception unit 41a of the illumination control device 4a receives the illumination condition transmitted from the illumination condition transmission device 1a and outputs it to the illumination control unit 42a. The illumination control unit 42a controls the illumination device 6a based on the input illumination condition. As a result, the illumination device 6a is turned on (step S6). For the same reason, the illumination devices 6b and 6c are also turned on. As a result, the pressing device 2a is illuminated by the lighting devices 6a to 6c. At this time, for example, an operator visually recognizes the press working apparatus 2a in order to confirm the cause of the stop of the press working apparatus 2a.

Even after the illumination is turned on, the illumination condition transmitter 1a continues to operate. The wattmeter 10a measures the power consumption of the press working apparatus 2a (step S7) and outputs it to the operating state determination unit 12a. The operating state determination unit 12a determines whether or not the measured power consumption is now greater than or equal to a threshold value (step S8).

When the result of determination in step S8 is “true” (Yes), the operating state determination unit 12a determines that the operating state of the press working apparatus 2a is in operation (step S9). Based on the determination result, the illumination condition acquisition unit 13a acquires the illumination condition corresponding to the operation during operation from a memory (not shown) (step S10), and outputs it to the transmission unit 14a. This illumination condition specifies that the illumination is turned off. As shown in FIG. 2, the transmission unit 14a outputs the input illumination condition to the transmission range 60a (step S11). As a result, the transmitted lighting conditions reach the lighting control devices 4a to 4c.

The reception unit 41a of the illumination control device 4a receives the illumination condition transmitted from the illumination condition transmission device 1a and outputs it to the illumination control unit 42a. The illumination control unit 42a controls the illumination device 6a based on the input illumination condition. As a result, the illumination device 6a is turned off (step S12). For the same reason, the illumination devices 6b and 6c are also turned on. As a result, during the operation of the press working apparatus 2a, the illumination is not illuminated again. As a result, the power consumption in the lighting devices 6a to 6c can be reduced during the unmanned automatic operation of the lighting condition transmitter 1a.

The process shown in FIG. 4 returns to step S1 after step S12. That is, unless special conditions are satisfied, the processes in steps S1 to S12 are repeated.

An example of exiting this iterative process will be described below. This is a kind of exception processing in the lighting control system 100. As shown in FIG. 4, when the result of determination in step S8 is “false” (No), the operating state determination unit 12a determines that the lighting on time in the lighting devices 6a to 6c is equal to or greater than a predetermined set value. It is determined whether or not there is (step S13). For example, a timer (not shown) starts measuring the illumination on time after the illumination condition is transmitted in step S5. This set value is, for example, 10 minutes.

When the result of the determination in step S13 is “false” (No), the processing shown in FIG. 4 returns to step S7. That is, as long as the illumination on time does not become the set value or more, the processes of steps S7, S8, and S13 are repeated.

On the other hand, when the result of determination in step S13 is “true” (Yes), the illumination condition acquisition unit 13a acquires the illumination condition that defines illumination off from the memory (step S14), and outputs the illumination condition to the transmission unit 14a. . The transmission unit 14a transmits the input illumination condition to the transmission range 60a (step S15). As a result, the illumination devices 6a to 6c are turned off.

The series of processing in steps S13 to S16 is a measure for forcibly turning off the illumination when the illumination on time continues beyond the set value. In other words, this is a measure for avoiding that the power is unnecessarily increased and the power consumption in the factory is unnecessarily increased. If it is necessary to continue the illumination for some reason after the illumination is forcibly turned off in step S16, the worker in the factory turns on the illumination of the illumination devices 6a to 6c.

(Advantages of the lighting control system 100)
In the large production line 50, there are many illuminations that illuminate each device in the production line 50, but the number of illuminations associated with each device varies, particularly due to the size of the device. Although not shown in FIG. 2, an apparatus that does not require illumination may be arranged on the production line 50. Therefore, if lighting is not properly controlled, wasteful illumination of unnecessary places occurs.

The lighting that illuminates each device is necessary during the time period in which the person is involved, such as setting the processing conditions of the device, changing the setup, and performing maintenance, but is not necessary while the device is operating unattended. Therefore, if the lighting is not properly controlled, unnecessary power consumption is generated due to unnecessary lighting during operation of the apparatus.

As described above, the illumination control system 100 according to the present invention appropriately determines various operating states (for example, operating, waiting, stopped) of the press working apparatus 2a in the production line 50, and based on the results. This is a system for automatically turning on / off or dimming (adjusting the amount of light) the illumination associated with the apparatus.

In the illumination control system 100, the illumination control devices 4a to 4c are obtained by acquiring the illumination conditions of the illumination devices 6a to 6c based on the power consumption of the press working device 2a or based on the sensing result of the processing position of the product in the press working device 2a. Send to. Thereby, it is possible to adjust or turn off unnecessary illumination when the illumination condition transmitter 1a is unattended and automatically operated. Thereby, useless consumption of electric power can be suppressed.

At this time, the illumination condition transmission device 1a transmits the illumination condition only to the illumination control devices 4a to 4c existing in the transmission range 60a set in advance in the transmission unit 14a. Thereby, the illumination can be controlled only in the illumination devices 6a to 6c controlled by the illumination control devices 4a to 4c.

As described above, in the illumination control system 100 according to the present embodiment, based on the operating state of each device such as the illumination condition transmission device 1a constituting the production line 50, only the related illumination is turned on / off, the brightness is adjusted, and the like. Do. Thereby, the following advantage can be enjoyed.

(1) It is possible to realize more stable and reliable lighting control than the conventional control system based on the behavior of a person who moves irregularly such that a large number of people move or hardly move.

(2) Wasteful power consumption due to lighting can be minimized by controlling the lighting of unnecessary lighting while the device is in operation.

(3) It is possible to prevent a problem that even the lighting necessary for the operator is turned off during the maintenance of the apparatus, the processing condition setting, or the setup change.

(4) Since the control range is limited only to the illumination device that illuminates the device, the illumination control system 100 having a relatively simple configuration enables accurate illumination control.

In summary, according to the present embodiment, it is possible to construct the lighting control system 100 that can be applied to facilities such as factories where a large number of people move and lighting to be controlled covers a wide range.

Further, in the present embodiment, the association between the manufacturing apparatus such as the illumination condition transmitting apparatus 1a in the manufacturing line 50 and the illuminating apparatuses 6a to 6f is determined in advance based on the wireless communication range in the transmitting units 14a to 14d. . That is, by limiting the communication range in advance for each illumination condition transmitting device, the lighting conditions for each device are based on the lighting required by the manufacturing device, such as the size of the press processing device 2a, the required illumination time, the illuminance, etc. Is set. As a result, in addition to the advantages (1) to (4) described above, the following complicated system configuration change operation is not required.

(5) Since it is not necessary to select an illuminating device that illuminates the manufacturing apparatus, it is necessary to reset the related illuminating apparatus when the manufacturing apparatus is moved due to a change in the manufacturing line 50 or when a new manufacturing apparatus is introduced. Absent.

(6) In the lighting control system 100, it is not necessary to manually set lighting, extinguishing, or dimming conditions each time.

[Embodiment 2]
A second embodiment according to the present invention will be described below with reference to FIG. In addition, the same code | symbol is attached | subjected to each member which is common in 1st Embodiment mentioned above, and detailed description is abbreviate | omitted.

In this embodiment, the illumination condition transmitter 1a automatically sets the transmission range when transmitting the illumination condition based on various parameters. The parameters include, for example, the size of the press processing apparatus 2a and the illumination range necessary for the press processing apparatus 2a. Such automatic setting allows the lighting devices 6a to 6c to be controlled to be appropriately changed according to the operating state of the press working apparatus 2a.

For example, in a specific operating state of the illumination condition transmitter 1a, it is assumed that only the illumination devices 6b and 6c among the illumination devices 6a to 6c need to be controlled. That is, in this operating state, it is assumed that the illumination device 6a does not need to illuminate the illumination condition transmission device 1a at all. When the operation state determination unit 12a determines that the press working apparatus 2a is in such an operation state, as shown in FIG. 5, the transmission range 60 narrower than the transmission range 60a in the first embodiment is given to the transmission unit 14a. Set. FIG. 5 is a diagram showing a transmission range 60e of the illumination condition transmitter in the illumination control system 100 according to the second embodiment of the present invention. Thereby, the transmission part 14a outputs illumination conditions to the transmission range 60e. As a result, the transmitted illumination condition does not reach the illumination control device 4a, but only reaches the illumination control devices 4b and 4c. Therefore, only the illumination of the illumination devices 6b and 6c is controlled.

As described above, the illumination control system 100 according to the present embodiment can more flexibly control the corresponding illumination devices 6a to 6c in accordance with the operating state of the press working device 2a.

[Embodiment 3]
A third embodiment according to the present invention will be described below with reference to FIG. In addition, the same code | symbol is attached | subjected to each member which is common in 1st and 2nd embodiment mentioned above, and detailed description is abbreviate | omitted.

(Lighting control system 100 ′)
In the present embodiment, lighting of the lighting devices 6a to 6f in the production line 50 is controlled by the lighting control system 100 ′. FIG. 6 is a diagram showing a configuration of an illumination control system 100 ′ according to the third embodiment of the present invention. As shown in this figure, the illumination control system 100 ′ includes illumination condition transmitters 1a, 1b, 1d, and illumination controllers 4a to 4f. Unlike 1st Embodiment, illumination control system 100 'is not provided with the illumination condition transmitter 1c. Therefore, the terminal processing device 2c is not provided with a unique illumination condition transmitter 1c.

In the manufacturing line 50, the terminal processing device 2c is a manufacturing device that operates in conjunction with the quality inspection device 2d. For example, if the quality inspection apparatus 2d is operated, the terminal processing apparatus 2c is also operated. On the other hand, if the quality inspection apparatus 2d is stopped, the terminal processing apparatus 2c is also stopped. That is, the operating state of the terminal processing apparatus 2c is always the same as that of the quality inspection apparatus 2d.

Therefore, in this embodiment, the terminal processing device 2c is handled as one of the constituent devices of the quality inspection device 2d. Therefore, the power consumption of the terminal processing apparatus 2c is not measured, and the operating state of the terminal processing apparatus 2c is not determined based on the measurement result. Instead, the illumination device 6d that illuminates the terminal processing device 2c is controlled based on the illumination condition transmitted from the illumination condition transmission device 1d provided in the quality inspection device 2d.

As shown in FIG. 6, a transmission range 60f wider than the transmission range 60d according to the first embodiment is preset in the quality inspection apparatus 2d. The transmission unit 14d transmits the illumination condition to the transmission range 60. The lighting control devices 4e and 4f exist in the transmission range 60f. Therefore, the illumination condition transmitted from the illumination condition transmitter 1d reaches both the illumination controllers 4e and 4f. The illumination control device 4e controls the illumination device 6e corresponding to the illumination condition transmission device 1c based on the received illumination condition. On the other hand, the illumination control device 4f controls the illumination device 6f corresponding to the quality inspection device 2d based on the received illumination condition.

As described above, in the present embodiment, the illumination control for the terminal processing device 2c is realized by the illumination condition transmitting device 1d provided in the quality inspection device 2d interlocked with the terminal processing device 2c. Therefore, since it is not necessary to provide the illumination condition transmitting device 1c in the terminal processing device 2c, the configuration of the illumination control system 100 ′ can be further simplified and the cost for realizing the illumination control system 100 ′ can be further reduced. it can.

Also in this embodiment, it is preferable that the transmission unit 14d is provided at a position closest to the ceiling in the quality inspection apparatus 2d. Moreover, it is preferable that the quality inspection apparatus 2d provided with the illumination condition transmission apparatus 1d is taller than the terminal processing apparatus 2c. As a result, the transmitter 14d can be provided at the tallest position in a series of devices that are linked in association with each other, so that the radio signal (illumination condition) transmitted from the transmitter 14d causes a communication failure. The possibility of receiving can be minimized.
