Description

[Technical field]

[0001] The present invention relates to an operating state determination system, and more particularly to one that receives light from a light-emitting display unit of an operating state display device. [Background technology]

[0002] A control panel, which is one of the operation status display devices for controlling control targets such as machine tools and electronic devices, will be explained using the control panel shown in Fig. 13. This information display device for control panels has an information display device main body 3 equipped with a small projector 6 and a microcomputer board section 7 installed inside a control panel 1, and the inside or surface of a door 4 of the control panel 1 is used as a screen 2 to display information such as equipment failures and operating status.

[0003] Conventionally, fault indications and operating status of equipment inside a control panel were indicated by LED lamps installed inside the panel, and the meanings of the lamps were confirmed by looking at a printed instruction manual. However, there were problems with this, as the lamps and letters were small and difficult to see, and the amount of information provided was small, making it difficult to understand (see Patent Document 1 for the above). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-78732 A Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned conventional operation status display device has the following points to be improved. With the conventional operation status display device, the information displayed by the small projector 6, such as the control panel, must be confirmed at the site where the control panel is installed. In other words, there is an issue to be improved in that it is not possible to remotely check the operation of the control panel or collect information about the control panel.

[0006] Furthermore, one option would be to modify the control panel, such as by adding a communications system to the control panel in order to enable remote checking of the control panel's operation or collection of information about the control panel. However, this would be costly and require a lot of effort to install, which is an area that needs improvement.

[0007] Furthermore, in general control panels that display the state of the controlled object by emitting light from light-emitting elements such as lamps and LEDs, it is necessary to ensure that the light emitted from the light-emitting elements is not obstructed from being visible from outside.

[0008] Therefore, an object of the present invention is to provide an operation status determination system that can more easily obtain the operation status of an operation status display device and determine the state of a control target. Another object of the present invention is to provide an operation status acquisition device that can more easily obtain the operation status of an operation status display device and easily network an operation status display device that is not networked. Effect of the Invention

[0009] The means for solving the problems in the present invention and the effects of the invention are described below.

[0010] The operating state determination system of the present invention is an operating state determination system that determines the operating state of an installation object in an operating state display device having a display light-emitting unit that emits light toward the outside depending on the operating state of a specified control object, using an operating state display acquisition device and an operating state determination device, wherein the operating state display acquisition device is arranged for each light-emitting display unit of the operating state display device, and has an operating state display acquisition unit that acquires the amount of received light and / or the color of the light emitted by the display issuing unit as light reception information, and a main body unit that transmits the light reception information to the operating state determination device, and the operating state determination device has a communication unit that receives the light reception information, and an operating state determination unit that uses the light reception information to determine the operating state of the installation object.

[0019] In the operation state display acquisition device according to the present invention, the operation state display acquisition section is cascade-connected to another one of the operation state display acquisition sections.

[0020] This simplifies the wiring structure and the wiring work.

[0022] This makes it possible to efficiently obtain light from the light-emitting display section of the operating status display device.

[0023] The operating state determination device of the present invention is an operating state determination device that determines the operating state of a specified installation object in an operating state display device having a display light-emitting unit that emits light toward the outside depending on the operating state of the installation object, and has a communication unit that receives light reception information indicating the amount of light emitted by the display light-emitting unit and / or the color of the light, and an operating state determination unit that uses the light reception information to determine the operating state of the installation object.

[0024] This makes it possible to easily determine the operating state of the installation object using the acquired light emission state of the display emitter.

[0025] The operating state determination program of the present invention is an operating state determination program that causes a computer to function as an operating state determination device that determines the operating state of a specified installation object in an operating state display device having a display light-emitting unit that emits light toward the outside depending on the operating state of the installation object, and causes the computer to function as a communication unit that receives light reception information indicating the amount of light emitted by the signal light and / or the color of the light, and an operating state determination unit that uses the light reception information to determine the operating state of the installation object.

[0026] This makes it possible to easily determine the operating state of the installation object using the acquired light emission state of the display emitter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. EXAMPLES

[0031] An operation state acquisition device according to the present invention will be described taking as an example a control panel operation state acquisition device 100 that uses a control panel as an operation state display device, which is one embodiment of the device.

[0032] 1. Configuration of control panel operation state determination system 100 The configuration of the control panel operation state determination system 100 will be described with reference to Fig. 1. The control panel operation state determination system 100 has a control panel operation state acquisition device 110 and a control panel operation state determination device 150. The control panel operation state acquisition device 110 identifies displays indicating the operation states of each electric device, etc. displayed by a control panel CP that houses electric devices, etc. for controlling machines, etc. installed in a factory, etc. The control panel operation state determination device 150 determines the operation state of the control panel CP from the display state, etc. of the control panel CP acquired by the control panel operation state acquisition device 100.

[0033] 1. Control panel CP The control panel CP on which the control panel operation state acquisition device 110 is installed will be described with reference to Fig. 2. The control panel CP has light-emitting display units CPa (CPa-1 to CPa-5), switches CPb (CPb-1 to CPb-5), and pointer display units CPc (CPc-1, CPc-2) at positions that can be seen from the outside when the door of the housing CPB is opened. The control panel CP has various electric devices and the like inside the housing CPB.

[0034] The light-emitting display unit CPa is disposed on the front panel of the control panel CP so as to emit light mainly from the front toward the outside. Therefore, a user who wishes to check the operating state of the controlled object by the light-emitting display unit CPa mainly checks the light emitted by the light-emitting display unit CPa from one direction of the control panel CP, the front.

[0035] The light-emitting display unit CPa has a thin, cylindrical, colored transparent housing. The light-emitting display unit CPa has a light-emitting unit such as an LED inside the transparent housing. The light-emitting display unit CPa emits the color of the transparent housing to the outside by the light-emitting unit inside the transparent housing emitting light.

[0036] In the control panel CP shown in FIG. 2, the light-emitting display units CPa-1, CPa-2, and CPa-5 have green transparent housings, the light-emitting display unit CPa-3 has a red transparent housing, and the light-emitting display unit CPa-4 has a yellow transparent housing.

[0037] 2. Control panel operation status signal acquisition device 110 The control panel operation state acquisition device 100 is installed in a control panel CP installed in a factory or the like, and identifies signals displayed by the control panel CP. The operation state determination device 150 determines the detailed operation state of an object controlled by the control panel CP from the display state of the control panel CP, etc.

[0038] The configuration of the control panel operational state acquisition device 110 will be described with reference to Fig. 3. Fig. 3 shows the control panel operational state acquisition device 110 as viewed obliquely from below.

[0039] As shown in FIG. 3, the control panel operation state acquisition device 110 has a main body 111, control panel display acquisition units 113 (113-1 to 113-5), and a connection line 115. The main body 111 is attached to the upper surface of the control panel CP. The control panel display acquisition unit 111 is attached to correspond to the emitting display unit CPa of the control panel CP. The control panel display acquisition unit 113 is attached above the light-emitting display unit CPa, at a position where the light emission of the emitting display unit CPa can be detected. The connection line 115 electrically connects between the main body 111 and a predetermined control panel display acquisition unit 113 (113-1) and between adjacent control panel display acquisition units 113. The main body 111 and the control panel display acquisition units 113 are connected in cascade by the connection line 115.

[0040] (1) Configuration of main body unit 111 The main body 111 has a main body housing 111a and a main body internal circuit 111b.

[0041] The configuration of the main body housing 111a will be described with reference to Fig. 4. Fig. 4 shows the main body housing 111a as viewed obliquely from above. The main body housing 111a has a hollow rectangular column shape. The main body housing 111a has an internal space 111a1 that houses the main body internal circuit section 111b, and a connection line opening 111a3 through which the connection line 115 passes.

[0042] The main body 111 is fixed to the upper surface of the control panel CP by a predetermined metal fitting via a main body mounting surface P111a, which is a predetermined surface of the main body housing 111a. The metal fittings are not shown in Figs. 3 and 4.

[0043] The hardware configuration of the main body internal circuit section 111b will be described with reference to Fig. 5. The main body internal circuit section 111b has a CPU 111ba, a memory 111bb, an interface section 111bc, a wireless communication section 111bf, and a power supply section 111bh.

[0044] The CPU 111ba performs processing based on the operating system (OS), the control panel display acquisition program, and other applications recorded in the memory 111bb. The memory 111bb provides a working area for the CPU 111ba. The memory 111bb records and holds the OS, the control panel display acquisition program, and other applications, as well as various data.

[0045] The interface unit 111bc is connected to the control panel display acquisition unit 113 via a connection line 115, and acquires light reception information (described later). The interface unit 111bc also transmits the acquired light reception information to the CPU 111ba.

[0046] The wireless communication unit 111bf is connected to the control panel operation state determination device 150 and transmits and receives data. The wireless communication unit 111bf performs wireless communication using, for example, wireless LAN (Local Area Network) technology. Note that an address that uniquely identifies a position on the network is set in advance in the wireless communication unit 111bf.

[0047] The power supply unit 111bh has an internal power supply 111bh1, such as a button battery, and a solar battery 111bh2 (see FIG. 4) that are housed inside the main body 111. The power supply unit 111bh supplies a predetermined amount of power to each component of the main body internal circuit unit 111b.

[0048] (2) Configuration of the control panel display acquisition unit 113 As shown in FIG. 3, the control panel display acquisition unit 113 has a control panel display acquisition housing unit 113a (hereinafter referred to as the acquisition housing unit 113a) and a control panel display acquisition internal circuit unit 113b (hereinafter referred to as the acquisition internal circuit unit 113b).

[0049] The configuration of the acquisition housing part 113a will be described with reference to Fig. 6. Fig. 6 shows the acquisition housing part 113a as viewed obliquely from below. The acquisition housing part 113a has a hollow rectangular column shape. The acquisition housing part 113a has an internal space 113a1 that houses the acquisition internal circuit part 113b, a connection line opening 113a3 that passes the connection line 115, and a light emission acquisition opening 11a5 that acquires light emitted by the light emitting display part CPa of the control panel CP.

[0050] The control panel display acquisition unit 113 can acquire the emission of the light-emitting display unit CPa in correspondence with the light-emitting display unit CPa of the control panel CP, and is fixed in a position that does not impede visibility from the outside. For example, in the case of the control version CP of FIG. 2, the emitting display unit CPa is disposed on the front panel of the control panel CP so as to emit light from the front toward the outside, so the control panel display acquisition unit 113 is fixed to the upper part of the light-emitting display unit CPa and acquires the emission of the light-emitting display unit CPa from the lower side. This allows the control panel display acquisition unit 113 to acquire the emission of the light-emitting display unit CPa without impeding the emission of light from the front of the emitting display unit CPa toward the outside.

[0051] The control panel display acquisition unit 113 is fixed to the surface of the control panel CP on which the light-emitting display unit CPa is arranged, via a control panel display acquisition unit attachment surface P113a, which is a predetermined surface, using adhesive tape or the like. The control panel display acquisition unit attachment surface P113a corresponds to the surface attached to the front panel of the control panel CP, that is, the surface along the front panel of the control panel CP.

[0052] The connection line openings 113a3 are arranged on the connection opening arrangement surfaces P113a3 that intersect with the control panel display acquisition unit mounting surface P113a1 and are positioned opposite each other. The light emission acquisition opening 113a5 is arranged on the light emission acquisition opening arrangement surface P113a5 that intersects with the control panel display acquisition unit mounting surface P113a1 and the connection opening arrangement surface P113a3 and is positioned on the light emission display unit CPa side. In other words, the light emission acquisition opening 113a5 is arranged so as to open toward the light emitting display unit CPa side of the control panel CP.

[0053] The hardware configuration of the acquisition internal circuit unit 113b will be described with reference to Fig. 7. The acquisition internal circuit unit 113b acquires the amount of light (illuminance) emitted by the light-emitting display unit CPa of the control panel CP. The acquisition internal circuit unit 113b has a condenser lens 113b1, a photodiode 113b3, an optical system (not shown) such as a color filter, a communication control unit 113b5 that transmits an output signal of the photodiode to the internal circuit unit, a first communication interface 113b7, and a second communication interface 113b9.

[0054] The condenser lens 113b1 condenses the incident light from the outside onto the photodiode 113b3. The photodiode 113b3 acquires the incident light condensed by the condenser lens 113b1 and converts it into an electrical signal as light reception information. The optical axis J113b1 of the condenser lens 113b1 is disposed in a direction toward the light-emitting display unit CPa of the control panel CP.

[0055] The color filter is disposed in front of the condenser lens 113b1 or the photodiode 113b3. The color filter is adjusted so that the light emitted from the light-emitting display unit CPa of the control panel CP corresponding to the control panel display acquisition unit 113 can be easily transmitted through the color filter.

[0056] The communication control unit 113b5 transmits to the main body internal circuit unit 111b of the main body unit 111, obtainment unit identification information that uniquely identifies itself and the amount of light received by the photodiode as light reception information.

[0057] In this way, the control panel display acquisition unit 113 acquires the amount of light emitted by each of the light emitting display units PLa1 to PLa3, which is associated in advance with the color emitted by each of the light emitting display units CPa.

[0058] Furthermore, the control panel display acquisition unit 113 acquires the light emitted by the display light-emitting unit CPa of the control panel CP without blocking the light emitted by the display light-emitting unit CPa, that is, at a position that does not impair visibility.

[0059] 3. Control operation state determination device 150 (1) Configuration of the control panel operation state determination device 150 The hardware configuration of the control panel operation state determination device 150 will be described with reference to Fig. 8. The control panel operation state determination device 150 includes a CPU 150a, a memory 150b, a hard disk drive 150c (hereinafter referred to as HDD 150c), a keyboard 150d, a mouse 150e, a display 150f, an optical drive 150g, and a wireless communication unit 150h.

[0060] The CPU 150a performs processing based on the operating system (OS), the control panel operation state determination program, and other applications recorded in the HDD 150c. The memory 150b provides a working area for the CPU 150a. The HDD 150c records and holds the operating system (OS), the control panel operation state determination program, and other application programs, as well as other data.

[0061] The keyboard 150d and mouse 150e receive commands from the outside. The display 150f displays images such as a user interface. The optical drive 150g reads the control panel operation state determination program from the optical media 150p in which the control panel operation state determination program is recorded, and also reads other application programs from other optical media, thereby reading data from the optical media. The wireless communication circuit 150h connects to a predetermined network and transmits and receives information to and from external communication devices such as the control panel operation state acquisition device 100. Note that an address that uniquely identifies a position on the network is set in advance in the wireless communication unit 150h.

[0062] Second, operation of the control panel operation state determination system 100 The operation of the control panel operational state determination system 100 will be described with reference to Figs.

[0063] 1. Operation of the control panel display acquisition unit 113 The control panel display acquisition process executed by the communication control unit 113b5 of the control panel display acquisition unit 113 will be described with reference to the flowchart shown in FIG.

[0064] 8, when the power is turned on (S901), after the received light amount acquisition time has elapsed (S911), the communication control unit 113b5 acquires the value of the photodiode 113b3, i.e., the amount of received light (S913). The communication control unit 113b5 transmits the acquired amount of received light to the main body unit 111 as light reception information (S915).

[0065] Furthermore, after the power is turned on (S901), when the communication control unit 113b5 acquires light reception information from another control panel display acquisition unit 113 (S921), it transmits the acquired light reception information as is to the main body unit 111 (S923).

[0066] The communications control unit 113b5 repeats the processes of steps S911 to S915 and steps S921 to S923 until the operation is completed (S903).

[0067] 2. Operation of the main body unit 111 The control panel display acquisition process executed by the CPU 111ba of the main body internal circuit section 111b of the main body section 111 based on the control panel display main body acquisition program will be described with reference to the flowchart shown in FIG.

[0068] 10, when the CPU 111ba is powered on (S1001), it enters a light reception information waiting state. When the CPU 111ba acquires light reception information from the control panel display acquisition unit 113 (S1003), it acquires acquisition unit identification information and the amount of received light (S1005). The CPU 111ba temporarily stores the acquired acquisition unit identification information and the amount of received light in the memory 111bb in association with the acquisition time as acquired light reception information (S1007).

[0069] The CPU 111ba transmits the acquired light reception information to the control panel operation state determination device 150 at a predetermined time interval (S1009) (S1011).

[0070] The CPU 111ba repeats the processes of steps S1003 to S1015 until the operation is completed (S1013).

[0071] By using the control panel operation status acquisition device 110 in the control panel CP, the control panel CP, which was not networked before, can be easily networked. This makes it possible to easily acquire and centrally manage the status of the control target controlled by the control panel CP.

[0072] 3. Operation of the control panel operation state determination device 150 The control panel operational state determination process executed by the CPU 150a of the control panel operational state determination device 150 based on the control panel operational state determination program will be described with reference to the flowchart shown in FIG.

[0073] When the CPU 150a acquires the acquired light reception information (S1101), it extracts the acquisition unit identification information and the amount of received light from the acquired light reception information (S1103), and judges the display state of the light-emitting display unit CPa that emits light acquired by the control panel display acquisition unit 113 corresponding to the acquisition unit identification information (S1105). For example, in the light reception information, if the amount of received light of the control panel display acquisition unit 113 corresponding to the acquisition unit identification information fluctuates at a predetermined cycle, it is judged that the light-emitting display unit CPa is blinking, and it is judged that the operation state corresponds to the blinking of the corresponding light-emitting display unit CPa. For example, if it is blinking in red, it is judged that the controlled object is in an abnormal operation state. Also, in the light reception information, if the amount of received light of the control panel display acquisition unit 113 corresponding to the acquisition unit identification information is stable at a predetermined amount or more, it is judged that it is continuously lit, and it is judged that the operation state corresponds to the continuous lighting of the corresponding light-emitting display unit CPa. For example, if it is continuously lit in green, it is judged that the controlled object is in a normal operation state.

[0074] In addition, to determine the display state of the light-emitting display unit CPa in the control panel operation state determination device 150, for example, a controlled object operation state table that associates the lighting state of the light-emitting display unit CPa of the control panel CP with the state of the controlled object is stored in advance in the memory 150b or the HDD 150c.

[0075] The CPU 150a repeats the operation state determination process of steps S1101 to S1105 until the operation is completed (S1107).

[0076] In this way, the operating state of the installation object can be easily determined based on the light emitting state of the display light emitting part CPa of the control panel CP.

[0077] [Other embodiments] (1) Control panel display acquisition unit 113: In the above-mentioned first embodiment, the control panel display acquisition unit 113 is attached to the upper part of the light-emitting display unit CPa of the control panel CP. However, the control panel display acquisition unit 113 is not limited to the illustrated position as long as it can acquire the light emission of the light-emitting display unit CPa and does not interfere with the light emission of the light-emitting display unit CPa. For example, it may be located to the side or below the light-emitting display unit CPa. In this case, the light emission acquisition opening 113a5 is arranged so as to open toward the light-emitting display unit CPa side.

[0078] (2) Method of mounting the control panel display acquisition unit 113: In the above-mentioned embodiment 1, the signal lamp display acquisition unit 113 is fixed to the control panel CP by adhesive tape or the like, but the method is not limited to the illustrated one as long as it can mount the control panel display acquisition unit 113 to the control panel CP. For example, as shown in Fig. 12A, the control panel display acquisition unit 113 may be mounted to a mounting bracket 201 that is sandwiched and fixed between the bezel of the light-emitting display unit CPa of the control panel CP and the front panel of the control panel CP. Note that in Fig. 12A, the connection wire 115 that connects the main body unit 111 and the signal lamp display acquisition unit 113 is omitted.

[0079] 12B, instead of using a mounting bracket arranged for each control panel display acquisition unit 113, the control panel display acquisition unit 113 may be attached to the control panel CP using a mounting bracket 301 capable of mounting multiple control panel display acquisition units 113. Note that, also in FIG. 12B, the connection wire 115 connecting the main body unit 111 and the signal lamp display acquisition unit 113 is omitted.

[0080] (3) Shape of the main body housing 111a and the control panel display housing 113a: In the above-mentioned embodiment 1, the main body housing 111a is a hollow prism, but the shape is not limited to the illustrated one as long as the main body internal circuit 111b can be disposed therein. For example, the main body housing 111a may be a hollow cylinder. The same applies to the control panel display acquisition unit 113.

[0081] (4) Configuration of the control panel display acquisition unit 113: In the above-mentioned embodiment 1, the control panel display acquisition unit 113 has the condenser lens 113b1, but is not limited to the illustrated one as long as the photodiode 113b3 can receive a predetermined amount of light. For example, the condenser lens 113b1 may not be used.

[0082] (5) Number of control panel display acquisition units 113: In the above-described first embodiment, the control panel display acquisition units 113 are arranged on some of the horizontally arranged light-emitting display units CPa of the control panel CP, but they may be arranged on only the necessary light-emitting display units CPa. For example, the control panel display acquisition units 113 may be arranged on all the light-emitting display units CPa of the control panel CP.

As a result, if the illuminance of the space in which the control panel display acquisition device 110 is installed is equal to or lower than a predetermined amount, it is determined that the time is outside the operating hours of the installation object, such as at night, and power can be saved by stopping the operation of the control panel display acquisition device 110. Note that a solar cell may be used as the illuminance acquisition unit.

[0091] (12) Addition of a vibration detection unit: In the above-described first embodiment, a vibration detection unit that detects vibrations may be further disposed in the main body unit 111. The vibration detection unit can detect an impact on the main body unit 111 and / or a control panel or the like to which the main body unit 111 is attached, and if the main body unit 111 has a door, the opening and closing of the door. If vibration or impact greater than expected is detected, or if vibration is detected at a time when opening and closing of a door is not expected, such as at night, the CPU 111ba of the main body internal circuit unit 111b may transmit an alarm via the wireless communication unit 111bf.

[0092] Also, by detecting vibrations of the main body 111, it may be possible to detect whether the control panel CP is operating or not.

[0093] (13) Illumination of the control panel CP: In the above-mentioned embodiment 1, as shown in Fig. 2, the light-emitting display CPa of the control panel CP has a flat light-emitting surface, but is not limited to the illustrated one as long as the light emission can be recognized from the outside. For example, it may have a dome-shaped light-emitting surface that protrudes in a hemispherical shape toward the outside.

[0094] (14) Configuration of the main body internal circuit unit 111b: In the above-mentioned first embodiment, the main body internal circuit unit 111b executes the control panel display acquisition program using the CPU 111ba, but is not limited to the example as long as it executes the control panel display acquisition program. For example, the control panel display acquisition program may be executed by a logic circuit.

[0095] (15) Processing executed by the main body internal circuit section 111b: In the above-described first embodiment, the flowchart of FIG. 10 was shown as the processing for realizing the control panel display acquisition program, but the processing is not limited to the illustrated flowchart as long as the control panel display can be acquired.
