Description

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

The present invention relates to an illumination condition transmission apparatus, an illumination condition transmission method, a lighting condition control system, a program, and a recording medium for controlling illumination of an automatically operable device.

Generally, in a facility (for example, a factory) that performs production activities using a large processing device or the like, power is consumed in a ratio as exemplified in FIG. FIG. 7 is a circular chart showing an example of the ratio of power consumption in a production activity facility such as a general factory. As shown in the figure, among the power consumption as a whole, the power consumption due to the production power that is caused by the processing device for the production activity is the largest. On the other hand, the power consumption of lighting in the factory also accounts for a large proportion.

In the past, in reducing the power consumption of such lighting, (1) the unnecessary illumination is turned off by manual diligence; (2) the illumination of the fluorescent lamp or the like is reduced to a minimum required; or (3) A method of investing in LED lighting or the like that consumes less power. However, due to recent years The increase in awareness of carbon dioxide reduction is required to reduce power consumption more than the power consumption reduced by such conventional methods. Therefore, there has been a demand for a control system that can automatically select and turn off unnecessary lighting to suppress power consumption to a minimum.

An example of a method according to this requirement is proposed in Patent Document 1 and Patent Document 2. In particular, the documents disclose an invention in which the movement of a person in a facility is detected using a human body detecting sensor, and the illumination is turned on or off in conjunction with the movement. However, in the case where the movement of the person is small, or the number of illuminations to be controlled is large, there are many problems such as erroneous operation such as turning off the light even if it is necessary, or even if it is unnecessary. . Moreover, in the case where a plurality of human body detecting sensors are disposed in a moving range of a person, there is also a problem that the so-called control program becomes complicated.

On the other hand, techniques for avoiding such problems have been proposed in the past. For example, Patent Document 3 discloses a method of controlling an illumination using an IC tag to confirm an individual's ID and matching an individual's operation mode. Further, Patent Document 4 discloses a method of forcibly controlling the demand control of lighting in a case where the amount of electric power used in the entire factory exceeds a threshold value.

[Embodiment 1]

The first embodiment of the present invention will be described below with reference to Figs. 1 to 4 .

(Production line 50)

First, the configuration of the production line 50 and the illumination control system 100 of the present embodiment will be described with reference to Fig. 2 . FIG. 2 is a view showing a configuration of a 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, the production line 50 is arranged in the order of the press processing apparatus 2a, the integrated molding apparatus 2b, the terminal processing apparatus 2c, and the quality inspection apparatus 2d. The production line 50 is a production facility for continuously arranging various general self-operating manufacturing apparatuses for manufacturing a predetermined product at a production site of a factory or the like. In the present embodiment, the press working apparatus 2a is a metal part such as a terminal required for press working a product. The integrally formed device 2b integrally forms the terminal and the resin material of the casing constituting the product with the product. The terminal processing device 2c is a terminal for processing a product. The quality inspection device 2d checks the quality of the products and arranges the products.

In the production line 50, the press processing device 2a, the integrated molding device 2b, the terminal processing device 2c, and the quality inspection device 2d are all ones that can be automatically operated. That is to say, the devices are related to the automatic manufacture of articles by automatic operation, for example, in an unmanned environment in the middle of the night.

Since the production line 50 has these four manufacturing apparatuses, it is very large. Because it is impossible to illuminate the production line 50 with a lighting device Therefore, there are a plurality of lighting devices 6a to 6f in the factory having the production line 50. The illuminating devices 6a to 6f are all disposed on the upper portion of the production line 50, that is, the ceiling of the factory, and are illuminated from above the corresponding manufacturing device.

In the present 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 illuminable unit 2b can be illuminated. The illuminating device 6e is provided at a position where the terminal processing device 2c can be illuminated. The illuminating device 6f is provided at the position of the illuminable quality inspection device 2d.

(lighting control system 100)

In the present embodiment, the illumination of the illumination devices 6a to 6f in the production line 50 is controlled by the illumination control system 100. As shown in FIG. 2, the illumination control system 100 is provided with illumination condition transmission devices 1a to 1d and illumination control devices 4a to 4f.

The illumination condition transmission devices 1a to 1d are respectively provided in the press processing device 2a, the integrated molding device 2b, the terminal processing device 2c, and the quality inspection device 2d. In other words, the illumination condition transmitting devices 1a to 1d are incorporated in the manufacturing device as constituent elements of the respective manufacturing devices. As will be described in detail later, each of the illumination condition transmitting apparatuses 1a to 1d determines the operation state of the corresponding manufacturing apparatus, and transmits the predetermined lighting conditions based on the result to at least one of the corresponding lighting control apparatuses.

Further, the illumination condition transmitting devices 1a to 1d are not necessarily provided in the corresponding manufacturing device. For example, the illumination condition transmitting apparatuses 1a to 1d can be arranged in a form connected to the corresponding manufacturing apparatus in any place in the factory where the press processing apparatus 2a or the like exists.

The illumination control devices 4a to 4f are respectively provided in the illumination devices 6a to 6f. 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 in accordance with the illumination conditions received from the corresponding illumination condition transmission device.

(illumination condition transmitting device 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. 1 . Fig. 1 is a block diagram showing the configuration of an illumination condition transmission device 1a and the illumination control devices 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 transmission device includes a power meter 10a, a sensor 11a, an operation state determination unit 12a (determination unit), an illumination condition acquisition unit 13a (acquisition unit), and a transmission unit 14a (transmission unit). Although not described in detail, the illumination condition transmitting devices 1b to 1d are also provided with the same members as those of the members included in the illumination condition transmitting device 1a. In the present specification, each member included in each of the illumination condition transmitting devices 1a to 1d is distinguished by the letter of the member number constituting the providing member. For example, the illumination condition transmitting device 1c includes an operation state determination unit 12c and an illumination condition acquisition unit 13c.

Hereinafter, the functions of the respective members included in the illumination condition conveying device 1a will be briefly explained. The electric power meter 10a measures the power consumption of the press working apparatus 2a. The sensor 11a detects the state of the operating portion of the press working apparatus 2a. The sensor 11a is mounted, for example, as a position sensor or an image sensor.

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

In the present embodiment, the types of operation states determined by the operation state determination unit 12a are in operation, during standby, during stop, during startup adjustment, during program change, and during repair. According to the different operating states that the press processing device 2a can take, the corresponding lighting conditions are assigned and associated with the operating state, and are stored in advance in the memory. Each lighting condition defines information on the control content of the lighting. In the present embodiment, the illumination conditions are used to specify the illumination (dimming) of the illumination, or the designation of the illumination to be turned on or off.

The specific content of the lighting conditions is predetermined in advance for each manufacturing device and for each operating state depending on the type of the corresponding manufacturing device and the type of the corresponding operating state. For example, the lighting conditions for "lighting on" are specified for the "stop" operating state. Even in the same operational state, there are cases where the lighting conditions are different depending on the type of the manufacturing device. For example, in the manufacturing apparatus that does not require the operator to perform the illumination for monitoring during the automatic operation of the unmanned person, such as the quality inspection device 2d, the operation state of the "operational operation" is "lighting off". On the other hand, in a manufacturing apparatus such as the integrated molding apparatus 2b that does not require a certain amount of illumination for monitoring by the operator during the automatic operation of the unmanned person, the "operational" operation state is not "lighting off". Correspond to "dimming (for example, lighting with 10% of the maximum light)".

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

As far as the lighting control system 100 is concerned, since the lighting conditions are transmitted by wireless signals, it is not necessary to additionally set the complicated wired device for transmitting the unlit condition to the ceiling. Moreover, it is not necessary to make the lighting device corresponding to the specific manufacturing device different from the system of the other lighting device. Therefore, the configuration of the lighting control system 100 can be further simplified, and the cost for installing the lighting control system 100 can be further reduced.

As shown in Fig. 2, the illumination condition conveying device 1a is provided at the highest position in the press working device 2a. Although not explicitly illustrated, the transfer portion 14a among the members constituting the illumination condition transmitting device 1a is disposed at a position closest to the ceiling in the press working device 2a. Therefore, the wireless signal (illumination condition) transmitted from the transmission unit 14a can be minimized due to the state of the illumination condition transmission device 1a or the state of another manufacturing device. Further, although not described in detail, the illumination condition transmitting devices 1b to 1d are also the same.

(lighting control devices 4a to 4c)

As shown in Fig. 1, the illumination control device 4a includes a receiving unit 41a (receiving unit) and an illumination control unit 42a (control unit). Moreover, the lighting control device 4b A receiving unit 41b (receiving unit) and an illumination control unit 42b (control unit) are provided. Further, the illumination control device 4c includes a receiving unit 41c (receiving unit) and an illumination control unit 42c (control unit). Although not described in detail, the illumination control devices 4d to 4f are also provided with the same members as the illumination control device 4a and the like. In the present specification, each member included in each of the illumination control devices 4a to 4f is distinguished by a letter of a member number constituting the member to be provided. For example, the illumination control device 4f includes a receiving unit 41f and an illumination control unit 42f.

Hereinafter, the functions of the respective members included in the illumination control device 4a will be briefly explained. The receiving unit 41a receives the lighting conditions transmitted from the illumination condition transmitting device 1a. The illumination control unit 42a controls the illumination in the illumination device 6a in accordance with the received illumination conditions.

(transmission range 60a~60d)

In the present embodiment, the illumination control devices 4a to 4c individually control the illumination of the illumination devices 6a to 6c in accordance with the illumination conditions transmitted from the illumination condition transmission device 1a. Further, the illumination control device 4d controls the illumination of the illumination device 6d in accordance with the illumination conditions transmitted from the illumination condition transmission device 1b. Further, the illumination control device 4e controls the illumination of the illumination device 6e in accordance with the illumination conditions transmitted from the illumination condition transmission device 1c. Further, the illumination control device 4f controls the illumination of the illumination device 6f in accordance with the illumination conditions transmitted from the illumination condition transmission device 1d.

The precise individual control of such illumination is achieved in accordance with the transmission ranges 60a to 60d defined in each of the illumination condition transmission devices 1a to 1d. As shown in FIG. 2, the illumination control devices 4a to 4c are present in the transmission range 60a. On the other hand, the illumination control devices 4d to 4f are not present in the transmission range 60a. Therefore, it is transmitted from the illumination condition transmitting device 1a. The lighting conditions are sent to only a part of the lighting control devices 4a to 4c among all the lighting control devices 4a to 4f. Thereby, the illumination condition transmitting device 1a can illuminate only the illumination devices 6a to 6c corresponding to the illumination condition transmission device 1a among all the illumination devices 6a to 6f in accordance with the determination result of the operation state in the press processing device 2a. It is controlled by the illumination control devices 4a to 4c. Therefore, for example, during the stop of the press working apparatus 2a, since the illumination of the illuminating devices 6d to 6f of the press processing apparatus 2a cannot be irradiated without opening, it is possible to prevent an unnecessary increase in power consumption in the factory.

Similarly, the illumination condition transmission device 1b provided in the integrated molding device 2b transmits only the illumination condition to the transmission range 60b. As a result, the lighting conditions are sent to the lighting control device 4d existing in the transmission range 60b, but are not sent to other lighting control devices. Therefore, it is possible to control the illumination of the illumination device 6d which can only illuminate the integrated molding device 2b.

Further, the illumination condition transmitting device 1c included in the terminal processing device 2c transmits only the illumination condition to the transmission range 60c. As a result, the lighting conditions are sent to the lighting control device 4e existing in the transmission range 60c without being sent to other lighting control devices. Therefore, it is possible to control the illumination of the illumination device 6e which can only illuminate the terminal processing device 2c.

Further, the illumination condition transmitting device 1d included in the quality inspection device 2d transmits only the illumination condition to the transmission range 60d. As a result, the lighting conditions are transmitted to the lighting control device 4f existing in the transmission range 60d without being transmitted to the other lighting control devices. Therefore, it is possible to control only the illumination of the illumination device 6f that can illuminate the quality inspection device 2d.

As described above, in the present embodiment, the relationship between each manufacturing device such as the illumination condition transmitting device 1a in the production line 50 and the individually controlled lighting device depends on the transmission ranges 60a to 60d in the respective lighting condition transmitting devices 1a to 1d. It is pre-specified. Therefore, after moving the press processing apparatus 2a to another location, for example, it is not necessary to select a controlled lighting apparatus corresponding to the press processing apparatus 2a and perform resetting. The reason is that the lighting device 60a newly provided in the illuminating condition conveying device 1a of the press working device 2a is newly set up corresponding to the illuminating device of the press working device 2a.

(Details based on the judgment of the operating state of power consumption)

As described above, the operational state determining unit 12a can determine the operational state of the press working apparatus 2a based on the output from the sensor 11a. In this case, it is necessary for the sensor 11a to directly detect whether or not the metal part (work or the like) is conveyed in the press working apparatus 2a, or whether the press mold is moved up and down, or the like, and the operation state in the press working apparatus 2a. Therefore, in order to determine whether or not there is any position of the workpiece or the mold in the press working apparatus 2a, it is necessary to provide a plurality of sensors 11a as position sensors on the press working apparatus 2a. Further, there is a possibility that the operational state of the press working apparatus 2a during operation or stop is difficult to be correctly distinguished.

Therefore, it is preferable that the operational state determining unit 12a determines the operational state of the press working apparatus 2a based on the measurement result of the power consumption by the electric power meter 10a, based on the detection result of the sensor 11a. The reason is that if it is the electric power meter 10a, it is different from the position sensor, and it is not necessary to provide a plurality of parts in the press processing apparatus 2a. And it is also the operational status judgment. The fixed portion 12a can more easily and accurately determine the operational state of the press working device 2a based on the measurement result of the power consumption.

The details of the lighting condition determination based on the measurement result of the power consumption will be described below with reference to FIG. 3. FIG. 3 is a view showing changes in the time of power consumption in each of the manufacturing apparatuses such as the press processing apparatus 2a disposed in the production line 50.

The graph 70a in Fig. 3 shows the change in the time of 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 a threshold value of 80 or more. Therefore, the operational state determining unit 12a determines that the press working device 2a is in operation during the period 71a. During period 72a, the power consumption is below a threshold of 80. However, since a certain amount of electric power is consumed due to one of control, etc., the power consumption becomes a certain amount more than zero. In response to this, the operation state determining unit 12a determines that the press working apparatus 2a is in standby during the period 72a. During period 73a, the power consumption is below the threshold of 80 and is substantially near zero. In response to this, the operation state determining unit 12a determines that the press working device 2a is in the period 73a.

The graph 70b in Fig. 3 shows the change in the time of power consumption in the integrally formed device 2b. The vertical axis represents power consumption, and the horizontal axis represents time. During the period 71b, the power consumption is increased stepwise. The operation state determining unit 12b determines that the integrated molding apparatus 2b is in the startup adjustment in the period 71b in accordance with the change in the power consumption time in the period 71b. In general, even if it is based on the value of the power consumption at a certain point in time, it is impossible to determine whether or not the integral molding apparatus 2b is in the startup adjustment. The operation state determination unit 12b determines the operation state by transmitting a change in the power consumption time, thereby more accurately determining the operation state.

In the period 72b, the power consumption is equal to or higher than the threshold value (not shown). Therefore, the operation state determining unit 12b determines that the integrated molding apparatus 2b is in operation during the period 72b. In the period 73b, the power consumption is lower than a threshold value (not shown) and is substantially close to zero. Accordingly, the operation state determining unit 12b determines that the integrated molding apparatus 2b is in the middle of the period 73b.

The graph 70c in Fig. 3 shows the change in the time of power consumption in the terminal processing device 2c. The vertical axis represents power consumption, and the horizontal axis represents time. In the period 71c, the power consumption is lower than a threshold value (not shown) and is substantially close to zero. In response to this, the operation state determining unit 12c determines that the terminal processing device 2c is in the period 71c. In the period 72c, the power consumption is equal to or higher than the threshold value (not shown). Therefore, the operation state determining unit 12c determines that the terminal processing device 2c is in operation during the period 72c.

The graph 70d in Fig. 3 shows the change in the time of power consumption in the quality inspection device 2d. The vertical axis represents power consumption, and the horizontal axis represents time. In the period 71d, the power consumption is lower than a threshold value (not shown) and is substantially close to zero. In response to this, the operation state determining unit 12d determines that the quality inspection device 2d is in the period 71d. In the period 72d, the power consumption is equal to or higher than the threshold value (not shown). Therefore, the operation state determining unit 12d determines that the quality inspection device 2d is in operation during the period 72d.

(Flow of lighting control processing)

The flow of the illumination control processing in the present embodiment will be described below with reference to Figs. 2 to 4 . 4 is a flow chart showing the flow of lighting control processing in the lighting control system 100 according to the first embodiment of the present invention. Hereinafter, illumination control of the illumination condition transmission device 1a and the illumination control devices 4a to 4c will be described as an example.

In the production line 50 at night, the press processing apparatus 2a is automatically operated in an unmanned state. In the operation of the press processing apparatus 2a, the electric power meter 10a measures the power consumption of the press processing apparatus 2a (step S1), and outputs it to the operation state determination part 12a. The operation state determination unit 12a determines whether or not the measured power consumption is lower than a predetermined threshold value (step S2). When the result of the determination in step S is "NO" (No), the processing shown in Fig. 4 returns to step S1.

On the other hand, when the determination result in step S2 is YES (Yes), the operation state determining unit 12a determines that the operation state of the press working apparatus 2a is stopped (step S3). Here, the power consumption of the press working apparatus 2a is set to substantially zero. In accordance with the result of the determination, the illumination condition acquisition unit 13a acquires the illumination condition corresponding to the stop from the memory (not shown) (step S4), and outputs it to the transmission unit 14a. This lighting condition specifies that the lighting is turned on. As shown in FIG. 2, the transmission unit 14a transmits the input illumination conditions to the transmission range 60a (step S5). As a result, the transmitted illumination conditions are sent to the illumination control devices 4a to 4c.

The receiving unit 41a of the illumination control device 4a receives the illumination conditions transmitted from the illumination condition transmitting device 1a, and outputs it to the illumination control unit 42a. The illumination control unit 42a controls the illumination device 6a in accordance with the input illumination conditions. As a result, the illumination of the illumination device 6a is turned on (step S6). For the same reason, the illumination of the illumination devices 6b and 6c is also turned on. As a result, the press processing apparatus 2a is irradiated by the illumination devices 6a-6c. At this time, for example, the operator can visually check the press working apparatus 2a in order to ascertain the cause of the stoppage of the press working apparatus 2a.

After the illumination is turned on, the illumination condition transmitting device 1a also continues to operate. The electric power meter 10a measures the power consumption of the press processing apparatus 2a (step S7), and outputs it to the operation state determination part 12a. The operation state determination unit 12a determines whether or not the measured power consumption is equal to or greater than the threshold value (step S8).

When the result of the determination in step S8 is YES (Yes), the operational state determining unit 12a determines that the operational state of the press working apparatus 2a is in operation (step S9). In accordance with the result of the determination, the illumination condition acquisition unit 13a acquires illumination conditions corresponding to the operation from the memory (not shown) (step S10), and outputs it to the transmission unit 14a. This lighting condition specifies that the lighting be turned off. As shown in FIG. 2, the transmitting unit 14a outputs the input lighting conditions to the transmission range 60a (step S11). As a result, the transmitted lighting conditions are sent to the illumination control devices 4a to 4c.

The receiving unit 41a of the illumination control device 4a receives the illumination conditions transmitted from the illumination condition transmitting device 1a, and outputs it to the illumination control unit 42a. The illumination control unit 42a controls the illumination device 6a in accordance with the input illumination conditions. As a result, the illumination of the illumination device 6a is turned off (step S12). For the same reason, the illumination of the illumination devices 6b and 6c is also turned on. As a result, the illumination is no longer irradiated during the operation of the press processing apparatus 2a. Therefore, in the automatic operation of the illumination condition transmitting device 1a, the power consumption in the illumination devices 6a to 6c can be reduced.

Further, the processing shown in FIG. 4 returns to step S1 after step S12. That is, as long as no special conditions are established, the processing of steps S1 to S12 can be repeated.

An example of the departure from the reverse processing will be described below. This is an exception to the processing in the lighting control system 100. As shown in FIG. 4, when the determination result in step S8 is No (No), the operation state determination unit 12a determines whether or not the illumination ON time in the illumination devices 6a to 6c is equal to or greater than a predetermined set value (step S13). This illumination on time is determined, for example, after the illumination condition is transmitted in step S5, and a timer (not shown) starts measurement. This setting value is, for example, 10 minutes.

When the result of the determination in step S13 is "NO" (No), the processing shown in Fig. 4 returns to step S7. That is, as long as the illumination on time is not equal to or greater than the set value, the processing of steps S7, S8, and S13 is repeated.

On the other hand, when the determination result in the step S13 is YES (Yes), the illumination condition acquisition unit 13a acquires the illumination condition for specifying the illumination off from the memory (step S14), and outputs it to the transmission unit 14a. The transmitting unit 14a transmits the input lighting conditions to the transmission range 60a (step S15). As a result, the illumination of the illumination devices 6a-6c is turned off.

The series of processes of steps S13 to S16 is for forcibly turning off the illumination when the illumination on time continues to be above the set value. That is, in order to prevent unnecessary lighting from being continuously turned on, the power consumption in the factory is increased in vain. After the illumination is forcibly turned off in step S16, if it is necessary to continue illumination for some reason, the operator of the factory turns on the illumination of the illumination devices 6a-6c.

(Advantages of Lighting Control System 100)

Although there are a plurality of illuminations of the various devices in the illumination line 50 in the large production line 50, the number of illuminations associated with each device varies, particularly depending on the size of the device. Although not shown in Figure 2, there are also A device that does not require illumination is disposed in the production line 50. Therefore, if the lighting is not properly controlled, it will result in waste of unnecessary places.

It is necessary to illuminate the illumination of each device in the time zone in which the device is set in the processing conditions, program change, maintenance, etc., but it is not required during the automatic operation of the device in the absence of the device. Therefore, if the lighting is not properly controlled, a large waste of power is generated due to unnecessary illumination in the operation of the device.

As described above, the illumination control system 100 of the present invention appropriately determines various operational states (e.g., during operation, standby, and stop) of the press processing apparatus 2a in the production line 50, and automatically performs device-related illumination depending on the result. A system that turns on, off, or dims (amount of light adjustment).

In the lighting control system 100, the lighting conditions of the lighting devices 6a to 6c are obtained and transmitted to the lighting control devices 4a to 4c according to the power consumption of the press working device 2a or the processing position detection result of the product in the press working device 2a. . Therefore, it is possible to dim or turn off the unnecessary illumination of the illumination condition transmitting device 1a in the case of no one and automatic operation. Therefore, unnecessary power consumption can be suppressed.

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

As described above, in the illumination control system 100 of the present embodiment, only the illumination, the light-off, the brightness adjustment, and the like of the related illumination are performed depending on the individual operation state of the device such as the illumination condition transmission device 1a constituting the production line 50. Thereby, the following advantages can be enjoyed.

(1) Stable and reliable lighting control can be realized as compared with a conventional control system based on the movement of a person who moves irregularly and hardly moves.

(2) The waste of power consumption of the illumination can be minimized by the illumination of unnecessary illumination in the operation of the finer control device.

(3) It is possible to prevent the illumination required by the operator from being turned off during the maintenance of the apparatus, the setting of the processing conditions, or the change of the program.

(4) Since the control range is limited to the illumination device of only the illumination device, accurate illumination control can be performed by the illumination control system 100 of a relatively simple configuration.

According to the present embodiment, it is possible to construct a lighting control system 100 that can be applied to a facility such as a factory having a wide illumination range and a wide range of illumination.

Further, in the present embodiment, the connection between the manufacturing apparatus such as the illumination condition transmission device 1a in the production line 50 and the illumination devices 6a to 6f is determined in advance based on the wireless communication range in the transmission units 14a to 14d. In other words, the communication range is set in advance by the illumination device, and the illumination conditions are individually set by the device based on the size of the press processing device 2a, the required illumination time, the illuminance, and the like, and the illumination required by the manufacturing device. As a result, in addition to the advantages of the above (1) to (4), the following advantages can be enjoyed without requiring a complicated system configuration.

(5) Since it is not necessary to select an operation of illuminating the illumination device of the manufacturing apparatus, the movement of the manufacturing apparatus accompanying the change of the production line 50 or the like There is no need to reset the relevant lighting device when introducing new or new manufacturing equipment.

(6) The conditions for lighting, turning off or dimming in the lighting control system 100 are not necessarily set by the manual each time.

[Embodiment 2]

A second embodiment of the present invention will be described below with reference to Fig. 5 . In addition, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In the present embodiment, the illumination condition transmitting device 1a automatically sets the transmission range when the illumination conditions are transmitted in accordance with various parameters. The parameters include, for example, the size of the press working device 2a, the illumination range required for the press working device 2a, and the like. According to such automatic setting, the controlled lighting devices 6a to 6c can be appropriately changed in accordance with the operation state of the press working device 2a.

For example, in the specific operational state in the illumination condition transmitting device 1a, it is only necessary to control only the illumination devices 6b and 6c among the illumination devices 6a to 6c. That is, in this operational state, it is assumed that the illumination device 6a does not need to illuminate the illumination condition transmission device 1a. The operation state determination unit 12a determines that the press processing apparatus 2a is in such an operation state, and sets the transmission range 60 narrower than the transmission range 60a in the first embodiment to the transmission unit 14a as shown in Fig. 5 . Fig. 5 is a view showing a transmission range 60e of the illumination condition transmitting device in the illumination control system 100 according to the second embodiment of the present invention. Accordingly, the transmitting unit 14a outputs the lighting conditions to the transmission range 60e. As a result, the transmitted lighting conditions are not sent to the lighting control device 4a but only to the lighting 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 of the present embodiment can more appropriately control the corresponding illumination devices 6a to 6c in response to the operation state of the press processing device 2a.

[Embodiment 3]

A third embodiment of the present invention will be described below with reference to Fig. 6 . In addition, the same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.

(lighting control system 100')

In the present embodiment, the illumination of the illumination devices 6a to 6f in the production line 50 is controlled by the illumination control system 100'. Fig. 6 is a view showing the configuration of a lighting control system 100' according to a third embodiment of the present invention. As shown in the figure, the illumination control system 100' includes illumination condition transmission devices 1a, 1b, and 1d and illumination control devices 4a to 4f. Unlike the first embodiment, the illumination control system 100' does not include the illumination condition transmission device 1c. Therefore, the individual illumination condition conveying device 1c is not provided in the terminal processing device 2c.

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

Then, in the present 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 device 2c is not measured, and the operation state of the terminal processing device 2c is determined based on the measurement result. Instead, the illumination device 6d of the illumination terminal processing device 2c is controlled in accordance with the illumination conditions transmitted from the illumination condition transmission device 1d provided in the quality inspection device 2d.

As shown in FIG. 6, the quality inspection device 2d sets a transmission range 60f wider than the transmission range 60d of the first embodiment. The transmitting unit 14d transmits the lighting conditions to the transmission range 60. Illumination control devices 4e and 4f are present in the transmission range 60f. Therefore, the lighting conditions transmitted from the illumination condition transmitting device 1d are sent to both of the lighting control devices 4e and 4f. The illumination control device 4e controls the illumination device 6e corresponding to the illumination condition transmission device 1c in accordance with the received illumination conditions. On the other hand, the illumination control device 4f controls the illumination device 6f corresponding to the quality inspection device 2d in accordance with the received illumination conditions.

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

Also in the present embodiment, it is preferable that the conveying portion 14d is located closest to the ceiling in the quality inspection device 2d. Further, the quality inspection device 2d for setting the illumination condition transmitting device 1d is processed by the terminal. It is preferred that the device 2c is also taller. Therefore, since the transfer unit 14d can be placed at the highest back position among the serially connected device groups in association with each other, the possibility that the wireless signal (illumination condition) transmitted from the transfer unit 14d is blocked by communication can be minimized.

This can also be realized by using a CPU (Central Processing Unit) and by software.

In the latter case, the illumination condition transmission device 1a includes a CPU that executes a program command for realizing the software of each function, and a ROM (Read Only Memory; read only) that records the program and various materials readable by a computer (or CPU).

Furthermore, the present invention can also be realized by electronically transmitting the realized data signal of the buried carrier by the above program.
