  Hereinafter, a control device 10 according to an embodiment of the present invention will be described in detail with reference to the drawings.

Embodiment 1
The control device 10 according to the present embodiment is a PLC installed in a factory. The control device 10 configures a control system 100 as an FA (Factory Automation) with the device 40 connected via the communication path 30 as shown in FIG. 1. The control system 100 corresponds to a production system for producing a product. The control system 100 performs various processes represented by processing, monitoring and inspection on a workpiece flowing in a manufacturing line.

  The communication path 30 connects the control device 10 and the device 40 so that they can communicate with each other. The communication path 30 is an industrial control network implemented by communication lines installed in a factory. However, the communication path 30 may be an information network represented by LAN (Local Area Network), or may be a dedicated line.

  The device 40 is a device typified by a sensor device, an actuator or a robot installed in a manufacturing line. For example, in accordance with the detection value of the device 40 which is a sensor device, the control device 10 controls the operation of the device 40 which is a robot.

  Further, in addition to the control device 10 and the device 40, the control system 100 has a portable terminal 20 for displaying abnormality information notified from the control device 10. The abnormality information is information related to an abnormality occurring in the control device 10. The portable terminal 20 is a small computer device represented by a smartphone, a tablet terminal, and a wearable device. The user U1 operates the mobile terminal 20 to capture the control device 10 to obtain abnormality information.

  The control device 10 is a computer device that operates the manufacturing line by controlling the device 40. Further, when an abnormality occurs in the operation, the control device 10 notifies the outside of the occurrence of the abnormality by emitting light.

  Subsequently, hardware configurations of the control device 10 and the portable terminal 20 will be described. The control device 10 and the portable terminal 20 each include a processor 51, a main storage unit 52, an auxiliary storage unit 53, an input unit 54, an output unit 55, and a communication unit 56, as shown in FIG. The main storage unit 52, the auxiliary storage unit 53, the input unit 54, the output unit 55, and the communication unit 56 are all connected to the processor 51 via the internal bus 57.

  The processor 51 includes a central processing unit (CPU) or a micro processing unit (MPU). The processor 51 implements various functions of the control device 10 and the portable terminal 20 by executing the program 58 stored in the auxiliary storage unit 53, and executes the processing described later.

  The main storage unit 52 includes a random access memory (RAM). The program 58 is loaded from the auxiliary storage unit 53 into the main storage unit 52. The main storage unit 52 is used as a work area of the processor 51.

  The auxiliary storage unit 53 includes a non-volatile memory represented by an EEPROM (Electrically Erasable Programmable Read-Only Memory). The auxiliary storage unit 53 stores various data used for the processing of the processor 51 in addition to the program 58. The auxiliary storage unit 53 supplies the data used by the processor 51 to the processor 51 according to the instruction of the processor 51, and stores the data supplied from the processor 51.

  The input unit 54 includes an input device represented by a switch, an input key, a pointing device, and a camera. The input unit 54 acquires the information input by the user U1 and notifies the processor 51 of the acquired information.

  The output unit 55 includes output devices represented by an LED, a liquid crystal display (LCD), and a speaker. The output unit 55 presents various information to the user U1 according to the instruction of the processor 51.

  Communication unit 56 includes a communication interface circuit for communicating with an external device. The communication unit 56 receives a signal from the outside and outputs data indicated by the signal to the processor 51. Also, the communication unit 56 transmits a signal indicating data output from the processor 51 to an external device.

  The control device 10 and the portable terminal 20 may be configured by omitting a part of the hardware configuration shown in FIG. For example, when the control device 10 receives a user operation from the outside through communication by the communication unit 56, the input unit 54 of the control device 10 may be omitted. In addition, when the portable terminal 20 does not have a function of communicating with the outside, the communication unit 56 of the portable terminal 20 may be omitted.

  A front view of the control device 10 is schematically shown in FIG. As shown in FIG. 3, the control device 10 includes a plurality of LEDs 110 indicating the state of the control device 10, an execution switch 122 for causing the control device 10 to execute or stop the program written thereto, and the communication path 30. And a terminal 130 for connection. The terminal 130 corresponds to the communication unit 56.

  Each of the plurality of LEDs 110 corresponds to the output unit 55. The plurality of LEDs 110 have a ready LED 111 indicating whether the control device 10 is in a ready state, and an error LED 112 indicating the occurrence of an abnormality. When an abnormality occurs in the control device 10, the error LED 112 emits light according to the type of the abnormality.

  A visible light emission pattern of the error LED 112 is shown in FIG. As shown in FIG. 4, the error LED 112 lights up when a serious abnormality occurs in the control device 10 and blinks when a slight abnormality occurs in the control device 10. The error LED 112 is turned off when there is no abnormality in the control device 10.

  However, the light emission pattern shown in FIG. 4 is a pattern that can be visually recognized by the user U1, and the error LED 112 is a high speed light emission pattern in order to notify the portable terminal 20 of adding abnormality information. It emits light. Details of these patterns will be described later.

  The control device 10 and the portable terminal 20 exhibit various functions by the cooperation of the above-described hardware configuration. As shown in FIG. 5, the control device 10 determines, as its function, an abnormality detection unit 11 that detects an abnormality that occurs in the control device 10, and a determination unit that determines the type of the abnormality and acquires abnormality information related to this abnormality. 12 includes a storage unit 13 that stores various data, a light emission control unit 14 that causes the light emitting unit 15 to emit light, and a light emitting unit 15 that emits light.

  The abnormality detection unit 11 is mainly realized by the processor 51. The abnormality detection unit 11 monitors the operating state of the control device 10 and detects an abnormality that occurs in the control device 10. Specifically, the abnormality detection unit 11 monitors the information output from the components of the control device 10, and when there is information indicating an abnormality, notifies the determination unit 12 of information indicating that an abnormality is detected. . This information also includes the details of the anomaly. The abnormality detection unit 11 functions as an abnormality detection unit.

  The abnormality is that the control device 10 operates according to an instruction from the outside, and as a result, it becomes a state different from the state indicated by the instruction, which deviates from the intention of the user U1 who gave the instruction to the control device 10. It is a state. For example, when the control device 10 is powered on, it is expected that the control device 10 is ready to execute a program. In this case, when the program can not be executed due to a memory abnormality represented by, for example, a battery shortage or a buffer overflow, the abnormality detection unit 11 detects an abnormality.

  The abnormality may include various states, but in the following description, the unit configuration relating to the arithmetic abnormality of the processor 51, the memory card access abnormality with respect to the memory card which is an external recording medium, the battery error, and the configuration of the control device 10. An abnormality and a memory abnormality will be described as an example of the abnormality. However, the anomalies are not limited to these, and may include other types of anomalies.

  The determination unit 12 is mainly realized by the processor 51. The determination unit 12 determines the type of the abnormality detected by the abnormality detection unit 11 based on the determination information 131 stored in the storage unit 13. Further, the determination unit 12 acquires the abnormality information indicating the content of the abnormality detected by the abnormality detection unit 11 by reading the determination information 131 from the storage unit 13. The determination unit 12 functions as a determination unit.

  The storage unit 13 is mainly realized by the auxiliary storage unit 53. In FIG. 6, the discrimination information 131 stored in the storage unit 13 is illustrated. In the example illustrated in FIG. 6, the determination information 131 is data in a table format in which the abnormal content, the type of abnormality, and the error code as the abnormality information are associated. By referring to the discrimination information 131, the discrimination unit 12 discriminates the type of the abnormality corresponding to the content of the abnormality detected by the abnormality detection unit 11, and acquires the abnormality information on the detected abnormality.

  The determination information 131 may be information defined in advance when the control device 10 is shipped, or may be changed by the user U1. Further, the type of abnormality is an abnormality degree indicating the degree of abnormality in FIG. 6, but may be another type. For example, it may be a type indicating whether the cause of the abnormality relates to software or hardware. Further, the abnormality information is an error code, but may be other information.

  Returning to FIG. 5, the light emission control unit 14 is mainly realized by the processor 51. The light emission control unit 14 controls the timing of light emission by the light emitting unit 15 in a pattern according to the type of abnormality determined by the determination unit 12 and the abnormality information. The light emission control unit 14 functions as a light emission control unit.

  FIG. 7 shows an example of a light emission pattern according to the type of abnormality. In the example of FIG. 7, the type of the abnormality “severe” corresponds to the lighting pattern in which lighting is continued, and the type of the abnormality “mild” alternately repeats the lighting period of one second and the extinguishing period of one second. Corresponds to the blinking pattern. Below, the light emission pattern according to the classification of abnormality is called 1st waveform pattern.

  The first waveform pattern is a pattern indicating information by a waveform having a relatively longer time scale than a second waveform pattern described later. Specifically, the blinking pattern as the first waveform pattern is a pattern in which a lighting period longer than the lower limit value and a light-off period longer than the lower limit value are repeated, and the lower limit value indicates that the user U1 visually recognizes blinking. It is a value determined to the extent possible. Preferably, the lower limit corresponds to the critical fusion frequency of humans. The critical fusion frequency changes according to the conditions including the light source luminance, but is approximately 24 fps or more, so it is desirable to set the lower limit value to 42 milliseconds. However, it is more preferable to set the lower limit value to 80 milliseconds, since blinking may be caused when blinking can not be recognized depending on the degree of fatigue of the user U1 if blinking occurs in a period close to such critical fusion frequency. Furthermore, it is more preferable to set the lower limit value to 1 second in consideration of the elderly person or the user U1 with low vision. In addition, it can be said that the lighting pattern as a 1st waveform pattern is a pattern which repeats the lighting period which comprises a blink pattern.

  In the blink pattern of FIG. 7, although the lighting period and the lighting period having the same length are alternately repeated, the present invention is not limited thereto. For example, a lighting period of 1 second and a lighting off period of 2 seconds may be alternately repeated, or a lighting period of 1 second, a lighting off period of 2 seconds, a lighting period of 3 seconds, and a lighting off period of 4 seconds The cycle of seconds may be repeated. Moreover, in FIG. 7, although one of the lighting pattern and the one blinking pattern corresponds to the type of abnormality, it is not limited thereto. For example, any one of a plurality of different blinking patterns may correspond to the type of abnormality.

  By deforming part of the first waveform pattern as described above, a light emission pattern corresponding to an error code can be obtained as illustrated in FIG. In FIG. 8, lines L11, L12 and L13 correspond to the lighting patterns in FIG. 7, and lines L14 and L15 correspond to the blinking patterns in FIG. Further, lines L21, L22, L23, L24, and L25 respectively indicate a second waveform pattern as a light emission pattern modified from the first waveform pattern indicated by lines L11 to L15.

  In the example of FIG. 8, the error code "0100" corresponds to the second waveform pattern indicated by the line L21. Further, the error code "0101" corresponds to the second waveform pattern indicated by the line L22, and the error code "0110" corresponds to the second waveform pattern indicated by the line L23. The error code “1111” corresponds to the second waveform pattern indicated by the line L24, and the error code “1000” corresponds to the second waveform pattern indicated by the line L25.

  The second waveform pattern is a light emission pattern for causing the user U1 to recognize it as a pattern substantially equal to the first waveform pattern. The second waveform pattern indicates information including the type of abnormality determined by the determination unit 12 and the abnormality information. As shown in FIG. 8, the second waveform pattern is formed by providing a partial period 60 in which the light quantity is different from other periods in the lighting period of the first waveform pattern according to the error code, and deforming from the first waveform pattern. It is formed. Here, the partial period 60 is a light-off period shorter than the upper limit value. The upper limit value is a value defined to such an extent that the user U1 can not recognize blinking. The upper limit value is desirably 42 milliseconds corresponding to the critical fusion frequency of human being, similar to the above-mentioned lower limit value. However, depending on conditions, the critical fusion frequency may be 50 fps, and it is more desirable to set the upper limit value to 20 milliseconds. Furthermore, it can be said that it is preferable to make the upper limit smaller in order to ensure that the user U1 can not recognize blinking due to the provision of the partial period 60.

  The partial period 60 is imaged by the imaging unit 21 of the portable terminal 20 as a pattern indicating an error code. The frame rates of cameras that are becoming widespread in recent years are 60 fps, 120 fps, and 240 fps, and in order to support many such cameras, the upper limit mentioned above is 16 ms to 20 ms, or 16 ms It is suitable that it is within the range of 40 milliseconds.

  In FIG. 8, in the second waveform pattern corresponding to the error code "0100", the lighting period of four units is repeated four times, with one unit being 15 milliseconds, by providing the partial period 60 in the first waveform pattern. It becomes a pattern of 20 units. Similarly, the second waveform pattern corresponding to “0101” is a pattern including lighting periods of 5 units, 5 units, 3 units, and 3 units in order. The second waveform pattern corresponding to “0110” is a pattern including lighting periods of six units, two units, two units, and six units in order. The second waveform pattern corresponding to “1111” is a pattern including lighting periods of 5 units, 4 units, 3 units, and 4 units in order. The second waveform pattern corresponding to “1000” is a pattern including lighting periods of 6 units, 1 unit, 3 units, 3 units, and 2 units in order. Such a 20-unit-long pattern is periodically formed in the lighting period of the first waveform pattern.

  Note that, in FIG. 8, the time after 300 milliseconds corresponds to the turn-off period of the blinking pattern as the first waveform pattern. The partial period 60 is not provided in this turn-off period.

  Returning to FIG. 5, the light emitting unit 15 is realized mainly by the output unit 55 that is an LED, and corresponds to the error LED 112. The light emitting unit 15 is a monochrome LED element that emits orange light when current is supplied under the control of the light emission control unit 14 and turns off when the current supply is interrupted. By emitting light in the second waveform pattern, the light emitting unit 15 notifies the user U1 viewing the light emitting unit 15 of the type of abnormality excluding the abnormality information in the information indicated by the second waveform pattern, and The portable terminal 20 to be imaged is notified of information including the type of abnormality indicated by the second waveform pattern and the abnormality information. The light emitting unit 15 functions as a light emitting unit.

  As shown in FIG. 5, the portable terminal 20 has, as its function, an imaging unit 21 for imaging the light emitting unit 15, an analysis unit 22 for analyzing the imaged image, and a storage unit 23 for storing various data. , And a display unit 24 that displays the analysis result to the user U1.

  The imaging unit 21 is mainly realized by the input unit 54 which is a camera. The frame rate of this camera is 60 fps. The imaging unit 21 includes an array of imaging elements and a lens, and repeatedly transmits data indicating an image obtained by receiving light from the light receiving port to the analysis unit 22.

  The analysis unit 22 is mainly realized by the processor 51. The analysis unit 22 analyzes the light emission pattern of the error LED 112 captured in the image captured by the imaging unit 21 based on the analysis information 231 stored in the storage unit 23.

  The storage unit 23 is mainly realized by the auxiliary storage unit 53. Analysis information 231 stored in the storage unit 23 is illustrated in FIG. 9. In the example shown in FIG. 9, the analysis information 231 includes the first waveform pattern, the second waveform pattern in the lighting section of the first waveform pattern, the type of abnormality corresponding to the first waveform pattern, and an error as abnormality information. It is data in the form of a table in which codes are associated with each other. The second waveform pattern indicates the length of the lighting period formed by inserting the partial period 60 as shown in FIG. For example, in FIG. 9, "4-4-4-4" indicates that the lighting period of 4 units in length is repeated four times. By referring to the analysis information 231, the analysis unit 22 acquires the type of error and the error code from the captured image. The analysis information 231 may be information defined in advance when the portable terminal 20 is shipped, or may be changed by the user U1.

  The display unit 24 is mainly realized by the output unit 55. The display unit 24 displays the error code acquired by the analysis unit 22. An example of the screen 200 of the portable terminal 20 is shown in FIG. The example of FIG. 10 includes a sub screen 201 for displaying an image captured by a camera in real time, a guide 202 displayed in the sub screen 201, and a block 204 for displaying an abnormal content. When the user U1 adjusts the attitude of the portable terminal 20 and the image 203 of the error LED 112 appears in the guide 202, the result analyzed by the analysis unit 22 is displayed in the block 204.

  Subsequently, a notification process performed by the control device 10 will be described with reference to FIG. The notification process shown in FIG. 11 starts when the control device 10 is powered on.

  In the notification process, the abnormality detection unit 11 determines whether an abnormality has been detected (step S11). Step S11 corresponds to a detection step in which the abnormality detection unit 11 detects an abnormality in the control device 10. If it is determined that no abnormality is detected (step S11; No), the abnormality detection unit 11 repeats the determination in step S11 and waits until an abnormality is detected. On the other hand, when it is determined that an abnormality has been detected (step S11; Yes), the discrimination unit 12 discriminates the type of abnormality by referring to the discrimination information 131 for the abnormality determined to be detected in step S11. (Step S12), the abnormality information is acquired (step S13). Steps S12 and S13 correspond to a determination step in which the determination unit 12 in the control device 10 determines the type of abnormality and acquires the abnormality information.

  Next, the light emission control unit 14 causes the light emitting unit 15 to emit light with the second waveform pattern according to the type of abnormality determined in step S12 and the abnormality information acquired in step S13 (step S14). Thus, the user U1 can visually recognize the type of abnormality. Step S14 corresponds to a light emission control step in which the light emission control unit 14 causes the light emitting unit 15 to emit light in the control device 10. Thereafter, the notification process ends.

  Subsequently, display processing executed by the mobile terminal 20 will be described with reference to FIG. The display process shown in FIG. 12 starts when the application software of the portable terminal 20 is activated.

  In the display process, the imaging unit 21 images the light emitting unit 15 of the control device 10 (step S21). Specifically, the user U1 operates the mobile terminal 20 to photograph the light emitting unit 15.

  Next, the analysis unit 22 analyzes and acquires an error code indicated by the second waveform pattern of the light emitting unit 15 by referring to the analysis information 231 from the image captured in step S21 (step S22).

  Next, the display unit 24 displays the error code obtained as a result of the analysis in step S22 (step S23). Thereby, the user U1 can obtain the abnormality information by operating the mobile terminal 20. Thereafter, the display process ends.

  As described above, according to the control device 10, the light emitting unit 15 emits light in the second waveform pattern, whereby the user U1 who visually recognizes the light emitting unit 15 has an abnormality among the information indicated by the second waveform pattern. The type of abnormality excluding information is notified, and the type of abnormality and the abnormality information indicated by the second waveform pattern are notified to the portable terminal 20 that images the light emitting unit 15. Thereby, the user U1 can determine the type of abnormality by visually recognizing the LED without using the portable terminal 20 while providing the abnormality information to the outside. Thereby, the burden on the user U1 can be reduced.

  The first waveform pattern is a lighting pattern that repeats a lighting period longer than the lower limit, and a type of abnormality among a blinking pattern that alternately repeats a lighting period and a lighting period smaller than the lighting period and longer than the lower limit. Was the corresponding pattern. By using the first waveform pattern corresponding to such an abnormality type, the user U1 can easily judge the type of abnormality visually.

  Moreover, the above-mentioned lower limit was 42 milliseconds corresponding to human critical fusion frequency. Thus, the user U1 can reliably recognize different patterns.

  Further, the second waveform pattern is a pattern modified from the first waveform pattern by providing a partial period whose light intensity is different from other periods and shorter than the upper limit according to the abnormality information in the lighting period of the first waveform pattern. Met. Such a second waveform pattern can be easily generated by controlling the supply and interruption of the current to the light emitting unit 15. In addition, the second waveform pattern can be easily analyzed by the mobile terminal 20.

  Also, the above upper limit value corresponds to the critical fusion frequency of human being, and was 42 milliseconds longer than the length of one frame photographed by the camera. Thus, the user U1 does not recognize the second waveform pattern as it is, and the portable terminal 20 can reliably determine the second waveform pattern.

Second Embodiment
Subsequently, the second embodiment will be described focusing on differences from the above-described first embodiment. In addition, while using a code | symbol equivalent about the structure the same as that of the said Embodiment 1, or equivalent, the description is abbreviate | omitted or simplified. In the first embodiment, the period of the second waveform pattern is fixed, but a different period may be suitable depending on the camera of the portable terminal 20. In such a case, it is desirable to change the period of the second waveform pattern. Hereinafter, the form which adjusts this period is explained.

  As shown in FIG. 13, the control system 100 has a terminal 20a for changing the period of the second waveform pattern. The terminal 20a is an industrial computer or a general-purpose computer, and is connected to the control device 10 via a USB (Universal Serial Bus) cable or a LAN cable to communicate with the control device 10. The user U1 inputs a setting change command to the control device 10 by operating the terminal 20a.

  The control apparatus 10 has the reception part 16 which receives specification of the period of the light emission by a 2nd waveform pattern from the terminal 20a, as FIG. 14 shows. The reception unit 16 is mainly realized by the cooperation of the processor 51 and the communication unit 56. The receiving unit 16 functions as a receiving unit. The reception unit 16 notifies the light emission control unit 14 of the designated cycle. Then, the light emission control unit 14 causes the light emitting unit 15 to emit light repeatedly with the second waveform pattern of the cycle notified from the receiving unit 16.

  Subsequently, display processing executed by the mobile terminal 20 will be described with reference to FIG. As shown in FIG. 15, following step S22, the analysis unit 22 determines whether analysis is possible (step S24). Specifically, the analysis unit 22 determines whether it is possible to obtain an error code from the image captured by the imaging unit 21.

  If it is determined that analysis is possible (Step S24; Yes), the display unit 24 displays an error code (Step S23). On the other hand, when it is determined that analysis is not possible (Step S24; No), the display unit 24 acquires the frame rate of the imaging unit 21 (Step S25). Next, the display unit 24 displays an adjustment instruction of the cycle of the second waveform pattern (step S26). This enables analysis of the second waveform pattern at the frame rate acquired in step S25. For example, if the value of the frame rate acquired in step S25 is 30 fps, the unit time of the second waveform pattern illustrated in FIG. 8 is preferably 33 milliseconds or more, and the display unit 24 has a cycle An instruction to set to 700 milliseconds is displayed.

  The screen displayed in this example is shown in FIG. As shown in FIG. 16, in block 204, an instruction to set the period to 700 ms is displayed. Returning to FIG. 15, the display process ends following step S26.

  Thus, the user U1 can obtain the abnormality information by adjusting the light emission cycle using the terminal 20a and photographing the error LED 112 again. In addition, the control system 100 is configured using various portable terminals 20 having different frame rates, and the user U1 can obtain abnormal information.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  For example, in the above embodiment, the light emission pattern of the error LED 112 indicates both the type of abnormality and the abnormality information, but the present invention is not limited to this. For example, using the ready LED 111 and the error LED 112, the user U1 may be notified of the type of abnormality in a form that allows visual observation, and the abnormality information may be transmitted to the portable terminal 20. At that time, the first light emission pattern of the ready LED 111 and the error LED 112 may be a pattern according to the type of abnormality as shown in FIG. Then, a second waveform pattern may be formed that indicates the type of abnormality and the abnormality information by modifying the light emission pattern of one or both of the ready LED 111 and the error LED 112.

  Moreover, although the said embodiment demonstrated the example to which an error code is alert | reported as abnormality information, it is not limited to this. For example, as illustrated in FIG. 18, the abnormality information may include a “target unit” that is an identifier for identifying the control device 10 and a “station number” that is a communication identifier of the control device 10. Further, the abnormality information may include information indicating details of the abnormality, information indicating advice for coping with the abnormality, and access information represented by a URL address for accessing the information.

  Moreover, in the said embodiment, although the portable terminal 20 displayed the abnormality information shown by 2nd waveform pattern, it is not limited to this. For example, the portable terminal 20 may display the type of abnormality together with the abnormality information. In addition, the portable terminal 20 acquires the coping method corresponding to the error code by referring to the data stored in the storage unit 23 or by inquiring to an external server apparatus, as shown in FIG. It may be displayed on

  Moreover, although the partial period 60 was made into the light extinction period in the said embodiment, it is not limited to this. For example, as shown in FIG. 19, the second waveform pattern may be formed by providing a light reduction period having a smaller amount of light than the other period as the partial period 60 in the lighting period of the first waveform pattern. Further, as shown in FIG. 20, in the lighting period of the first waveform pattern, the second waveform pattern may be formed by providing, as the partial period 60, an enhancement period in which the light amount is larger than that of other periods. In general, the amount of light of the light emitting unit 15 which is an LED may be realized by blinking at a high speed to an extent that the portable terminal 20 can not recognize. By setting such a light reduction period or emphasizing period as the partial period 60, it is possible for the user U1 to recognize flicker in the lighting period as compared with the case where the non-lighting period is the partial period 60 as in the above embodiment. It can be avoided. Note that the turn-off period can be said to be a kind of light reduction period because the amount of light is smaller than the turn-on period.

  Further, as shown in FIG. 21, a second waveform pattern is formed by providing a partial period 60 in which the light quantity is different from the other periods in the light off period of the first waveform pattern, and deforming the first waveform pattern. It is also good.

  Moreover, although the example which employ | adopted monochrome LED as the light emission part 15 was demonstrated in the said embodiment, it is not limited to this. For example, a red LED and a green LED may be adopted as the light emitting unit 15, and a first waveform pattern and a second waveform pattern may be formed so as to change the color of light emitted by the light emitting unit 15. In the above embodiment, the discrimination unit 12 discriminates the type of abnormality by referring to the discrimination information 131 of the storage unit 13 and acquires the anomaly information, but the present invention is not limited to this. For example, the determination unit 12 may acquire at least one of the type of abnormality and the abnormality information by inquiring of a server device external to the control device 10.

  Also, the functions of the control device 10 and the portable terminal 20 can be realized by dedicated hardware or by a normal computer system.

  For example, the program 58 executed by the processor 51 is stored in a non-transitory computer-readable recording medium and distributed, and the program 58 is installed in a computer to configure an apparatus that executes the above-described processing. be able to. As such a recording medium, for example, a flexible disc, a compact disc read-only memory (CD-ROM), a digital versatile disc (DVD), and a magneto-optical disc (MO) can be considered.

  Alternatively, the program 58 may be stored in a disk device of a server device on a communication network represented by the Internet, for example, superimposed on a carrier wave and downloaded to a computer.

  The above-described process can also be achieved by executing the program 58 while transferring the program 58 via a communication network.

  Furthermore, the above-described processing can be achieved by executing all or a part of the program 58 on the server device and executing the program while transmitting and receiving information related to the processing via the communication network.

  When the OS (Operating System) shares and realizes the above functions, or when the OS and an application cooperate to realize it, etc., only the part other than the OS may be stored and distributed in the medium. You can also download it to your computer.

  Further, the means for realizing the functions of the control device 10 and the portable terminal 20 is not limited to software, and some or all of the means may be realized by dedicated hardware including a circuit.
