Description

  TECHNICAL FIELD The present invention relates to an equipment operation management apparatus, and more specifically, an equipment operation management apparatus and an equipment operation management method for monitoring the operating state of an equipment provided with an automatic operation device and managing a history of abnormalities occurring in the equipment. About.

  In recent years, automation has increased more and more in the manufacturing process and inspection process of various machines and devices, leading to the use of autonomous driving devices that operate autonomously such as various automatic assembly devices and automatic inspection devices. Yes. A production facility or the like is configured by using one or a plurality of such automatic driving devices.

  In addition, many automatic driving devices have a number of sensors in the device, and monitor the state of the device during automatic operation through these sensors, and have a function to determine whether it is in a normal operation state or an abnormal stop state. is doing. It also has a function of analyzing the cause of the abnormal stop state. Therefore, a facility operation management device that receives signals from each automatic operation device in the facility, such as the device state and the cause of the abnormal stop, and manages the entire facility is provided in the facility constituted by such an automatic operation device. If there is an automatic operation device that has stopped due to an abnormality, such an equipment operation management device identifies the automatic operation device, informs the facility administrator of the cause of the abnormal stop, and Maintenance and inspection work is facilitated. In addition, such equipment operation management devices record the history information of the operation status and abnormality occurrence status of each automatic driving device, and can be used as reference when discovering a failure that caused an abnormal stop or improving the equipment itself. Information is provided (see Patent Document 1).

  Conventionally, when an automatic operation device under the control of an equipment operation management device abnormally stops, the equipment operation management device assumes that the automatic operation device stops abnormally and then restarts operation once. Record.

  However, in the equipment as described above, if there is an automatic operation device that has stopped abnormally, the facility administrator will remove the cause of the abnormal stop and restart the operation continuously for the automatic operation device that has stopped abnormally. In addition, several trial runs are generally performed. If an abnormal stop occurs again during such a trial operation, the equipment operation management device records such an abnormal stop during the trial operation as a separate abnormal stop. Therefore, even if the facility administrator analyzes the abnormal stop information recorded in the equipment operation management device and identifies the abnormal stop cause that should be taken, the cause of the abnormal stop based on the analysis result is actually taken. It often happens that it is different from the cause of abnormal stoppage, and efficient improvements to the equipment cannot be implemented.

JP-A-5-264410

  In view of the above problems, an object of the present invention is to provide an equipment operation management apparatus and an equipment operation management method capable of more accurately recording the equipment state of an automatic operation apparatus under management.

  It is another object of the present invention to provide an equipment operation management apparatus and an equipment operation management method that can easily identify an abnormal stop factor that needs countermeasures against an abnormal stop that has occurred in a managed automatic driving apparatus.

  According to the form of claim 1 of the present invention, the equipment operation management device according to the present invention determines an abnormal stop caused by the same abnormal stop factor when a predetermined condition is satisfied for a plurality of abnormal stop information. Even if an abnormal stop occurs again by performing a trial operation in an automatic operation device that has generated an abnormal stop by having an abnormal stop information analysis unit that does not get caught in the abnormal stop during the trial operation, It is possible to easily identify an abnormal stop factor that truly requires countermeasures.

  In addition, as described in claim 2, an abnormal stop cancellation delay time is set, and an abnormal stop continuously generated within a certain period in the same automatic driving device is caused by the same abnormal stop factor. Therefore, it is possible to easily determine whether or not an abnormal stop is caused by the same abnormal stop factor without requiring a complicated determination process.

  Furthermore, as described in claim 3, by having a recording unit for recording an abnormal stop totaling table in which the abnormal stop information determined to be caused by the same abnormal stop factor is collected into one, it is really necessary to take measures. An abnormal stop factor can be easily acquired.

  In addition, as described in claim 4, by setting the abnormal stop cancellation delay time by the automatic operation device or the abnormal stop factor, a plurality of abnormal stops may be caused by the same abnormal stop factor or separately. It is possible to more accurately determine whether it is caused by an abnormal stop factor.

  Moreover, according to the form of Claim 5 of this invention, the equipment operation management method which concerns on this invention is an abnormal stop cancellation | release delay time at the time when the abnormal stop of the automatic driving device was complete | finished shown by abnormal stop total information. By comparing the abnormal stop release time obtained by adding the abnormal stop start time indicated in the abnormal stop information, the newly generated abnormal stop can be compared with the already recorded abnormal stop. It can be easily determined whether it is due to the same abnormal stop factor or due to a separate reason.

  Hereinafter, the facility operation management apparatus of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a production facility system including a facility operation management apparatus according to an example of the present invention.

  The production facility system 100 including the facility operation management device 1 according to an example of the present invention includes a plurality of automatic operation devices 2 to 6, and processes, assembles, and inspects workpieces and parts flowing through the production line 7 to manufacture products. To do. The automatic operation devices 2 to 6 are processing devices, assembly devices, inspection devices, or the like, autonomously determine their own device state, and transmit the device state information including the determination result to the equipment operation management device 1. In the device status information, in addition to the device ID for identifying the automatic driving device, if an abnormality has occurred in the automatic driving device, the abnormal code indicating the type of abnormality, the automatic driving device has stopped abnormally The abnormal stop start time that represents the completed time and the abnormal stop end time that represents the operation restart time are included. The equipment operation management apparatus 1 records and stores information on the apparatus state received from each of the automatic operation apparatuses 2 to 6 via the network 8. In addition, when an abnormality occurs in any of the automatic driving devices 2 to 6 and stops, information on when the abnormal stop factor is removed and the operation is restarted is received, and a record regarding the abnormal stop is left.

  Next, FIG. 2 shows a functional block diagram of the equipment operation management apparatus 1 according to an example of the present invention.

  As described above, the facility operation management apparatus 1 according to an example of the present invention receives information on the apparatus state from each of the automatic driving apparatuses 2 to 6, and particularly information on abnormal stop that has occurred in each of the automatic driving apparatuses 2 to 6. It is a recording device. And, in the same automatic driving device, when multiple abnormal stops occur, if the time difference between each abnormal stop is small, it is determined that those abnormal stops are caused by the same abnormal stop factor, This is an apparatus that allows the facility manager to easily identify the abnormal stop factor that should be taken by creating the result of counting as one abnormal stop information.

  As shown in FIG. 2, the facility operation management device 1 according to an example of the present invention is configured as a personal computer and software incorporated in the personal computer, and receives operation state information from each of the automatic driving devices 2 to 6. An information input unit 11, a control unit 10 for extracting and analyzing information related to an abnormal stop from the device state information received by the operation information input unit 11, and a recording unit for recording the abnormal stop information of the automatic driving device as a database 14.

  Furthermore, the facility operation management device 1 displays the abnormal stop information stored in the recording unit 14 and visually notifies the facility manager of the content of the abnormality that has occurred in each automatic driving device. Is provided.

  Hereinafter, each part of the equipment operation management apparatus 1 will be described in detail.

  The operation information input unit 11 includes a network communication device such as Ethernet (registered trademark) and a network driver, and performs network communication according to a communication protocol such as TCP / IP. And the apparatus status information from the automatic driving apparatuses 2-6 used as management object is received via the network 8. FIG. The received device status information is transmitted to the control unit 10.

  The recording unit 14 is composed of a secondary storage device such as a hard disk or an optical recording device and a recording medium, and records abnormal stop information relating to each abnormal stop generated in each of the automatic driving devices 2 to 6 as a history. The table 21 and the abnormal stop totaling table 31 that displays the abnormal stops caused by the same abnormal stop factor together as one abnormal stop are recorded.

  The display unit 15 is a monitor device such as a liquid crystal display, and displays the abnormal stop history table 21 and the abnormal stop total table 31 recorded in the recording unit 14 so that the facility manager can know the state of the facility and the state of occurrence of the abnormality. Visually communicate. In addition, the display unit 15 may be provided with an operation input device such as a touch panel or a touch pen, for example, so that the facility administrator can change the display content.

  The control unit 10 includes a computer arithmetic device, a read only memory (ROM) or a random access memory (RAM) that functions as a cache memory and a primary storage device, and software that is read and driven by the computer.

  In addition, the control unit 10 includes an abnormal stop information extraction unit 12 and an abnormal stop information analysis unit 13.

  Here, the abnormal stop information extraction unit 12 extracts abnormal stop information indicating an abnormal stop that has occurred in any of the automatic driving devices 2 to 6 from the device state information received from each of the automatic driving devices 2 to 6, and records it. The abnormal stop information is added to the abnormal stop history table 21 stored in the unit 14.

  Specifically, the device status information received from each of the automatic driving devices 2 to 6 is set in advance with a device status flag indicating different values depending on whether the automatic driving device is in a normal state or an abnormal state. (E.g., 0 for normal condition, 1 for abnormal condition). The abnormal stop information extraction unit 12 refers to the value of the device state flag to know that the automatic driving device is in an abnormal stop state. Here, the position of the device status flag in the data stream representing the device status information is determined in advance so that the abnormal stop information extraction unit 12 can refer to the device status flag (for example, it is arranged at the head of the data stream). .

  In each of the automatic driving devices 2 to 6, based on a signal from a sensor provided in the automatic driving device, whether the device is operating normally or an abnormal state in which some abnormality has occurred. judge. Then, the value of the apparatus state flag is set based on the determination result, and the apparatus state information is transmitted to the facility operation management apparatus 1 with other necessary information added. On the other hand, when the equipment operation management apparatus 1 receives the apparatus state information, it identifies the position of the apparatus state flag in the data stream representing the apparatus state information, and refers to the value of the apparatus state flag.

  Instead of setting the position of the device status flag in the data stream in advance, a unique tag may be set in the device status flag, and the value of the device status flag may be referred to based on the tag.

  The abnormal stop information extraction unit 12 refers to the device state flag from the device state information, and checks whether the value of the device state flag matches the value (0) indicating the normal state. If the value of the device state flag does not match the value indicating the normal state, information relating to the abnormal stop extracted from the device state information is recorded in the abnormal stop history table 21.

  Here, an abnormal stop history table 21 according to an example is shown in FIG.

  In the abnormal stop history table 21, an index 22 for distinguishing each abnormal stop that occurred, an identification number (device ID) 23 of the device that caused the abnormal stop, an abnormal code 24 indicating the cause of the abnormal stop of the device, an abnormal stop An abnormal stop start time 25 that indicates the time of occurrence, an abnormal stop end time 26 that indicates the time when the abnormal stop is exited and the apparatus resumes operation, and whether or not the abnormal stop is related to the previous abnormal stop that occurred in the same apparatus. The stop flag 27 is recorded as abnormal stop information in a record created for each abnormal stop. In the abnormal stop history table 21 of the example shown in FIG. 3A, one horizontal line is one record, and information described in that line represents abnormal stop information.

  Addition and update processing to the abnormal stop history table 21 in the abnormal stop information extraction unit 12 will be described below.

  First, when the abnormal stop information extraction unit 12 of the control unit 10 determines that an abnormal stop has occurred with reference to the device state flag included in the device state information, the abnormal stop history table 21 is read from the recording unit 14. Then, by referring to the index 22 in the abnormal stop history table 21, 1 is added to the index 22 having the highest number to generate a new record. Then, by referring to the equipment state information, the device ID 23 and the abnormality code 24 are acquired, and those values are written in the newly generated record. Further, the abnormal stop start time 25 included in the apparatus state information is written in the record. Then, the abnormal stop history table 21 to which the record is added and the abnormal stop information is added is stored in the recording unit 14 again. In addition, the control unit 10 stores the device ID 23 that is abnormally stopped in a cache memory or the like.

  Thereafter, every time device status information is received, the control unit 10 checks whether or not the device ID indicated in the device status information matches the device ID 23 stored in the cache memory as being abnormally stopped. If the device state information matches the device ID 23 of the device in the abnormally stopped state, the abnormal stop history table 21 is read from the recording unit 14 and passed to the abnormal stop information extracting unit 12 together with the device state information.

  The abnormal stop information extraction unit 12 refers to the device state flag from the device state information and determines whether or not the device is in a normal state. And when it determines with a normal state, the newest record (namely, the thing with the largest number described in the index 22 in the same apparatus ID23) from the abnormal stop log | history table 21 corresponds with apparatus ID23 of an applicable automatic driving | operation apparatus. ). The abnormal stop end time included in the device status information is written in the abnormal stop end time 26 of the specified record and stored in the recording unit 14.

  Next, the operation of the abnormal stop information analysis unit 13 will be described.

  The abnormal stop information analyzing unit 13 refers to the abnormal stop history table 21 and the abnormal stop totaling table 31 stored in the recording unit 14, and abnormally stops the latest abnormal stop information 28 recorded in the abnormal stop history table 21. Compared with the abnormal stop total information 37 recorded in the total table 31, the interval of occurrence of the abnormal stop is examined to determine whether it is due to the same abnormal stop factor or a separate abnormal stop factor. . Then, based on the determination result, when it is determined that it is caused by the same abnormal stop factor, the recorded content of the abnormal stop total information 37 is rewritten using the abnormal stop information 28 and the abnormal stop total table 31 is updated. On the other hand, the abnormal stop information 28 determined to be caused by a separate abnormal stop factor generates a new record in the abnormal stop total table 31 and records it as separate abnormal stop total information.

  Here, the abnormal stop totaling table 31 will be described with reference to FIG.

  In the abnormal stop total table 31, as in the abnormal stop history table 21, an index 32 assigned to each record, an identification number (device ID) 33 of the device that caused the abnormal stop, and the abnormal stop cause of the device stop are displayed. It is determined that an abnormal stop 34 indicating an abnormal code 34, an abnormal stop start time 35 indicating the time at which the abnormal stop has occurred, and an abnormal stop end time 36 indicating a time at which the apparatus has resumed operation are caused by the same abnormal stop factor. Record the abnormal stop information for each abnormal stop total information.

  Next, update processing of the abnormal stop total table 31 will be described.

  When new abnormal stop information is written in the abnormal stop history table 21 (here, the abnormal stop end time 26 is written), the abnormal stop information analyzing unit 13 stores the abnormal stop history stored in the recording unit 14. The table 21 and the abnormal stop total table 31 are read out. However, the abnormal stop history table 21 and the abnormal stop totaling table 31 may be read at regular intervals such as one hour, one day, and one week.

  Next, the device ID 23 is acquired from the abnormal stop history table 21 from the latest abnormal stop information 28 (the one with the largest number described in the index 22). Then, the latest abnormal stop total information 37 having the same device ID as the above-described device ID 23 is specified from the abnormal stop total table 31. Then, the abnormal stop end time 36 indicated in the abnormal stop total information 37 is acquired.

  Next, the abnormal stop information analysis unit 13 sets a time obtained by adding a preset abnormal stop release delay time td to the abnormal stop end time 36 of the automatic driving device acquired from the abnormal stop total information 37 as the abnormal stop release time tr. To do. If the abnormal stop start time 25 indicated in the latest abnormal stop information 28 acquired from the abnormal stop history table 21 is earlier than the abnormal stop release time tr, the latest abnormal stop information 28 is calculated as an abnormal stop count. It is determined that the abnormal stop indicated by the abnormal stop total information 37 acquired from the table 31 and the abnormal stop caused by the same abnormal stop cause are indicated.

  If the abnormal stop information analysis unit 13 determines that the abnormal stop is the same, the abnormal stop information analysis unit 13 sets the abnormal stop end time 36 of the abnormal stop total information 37 to the abnormal stop end time 26 included in the abnormal stop information 28. replace.

  On the other hand, when the abnormal stop start time 25 and the abnormal stop release time tr are the same or the abnormal stop start time 25 is later, the latest abnormal stop information 28 is the abnormal stop total information acquired from the abnormal stop total table 31. It is determined as an abnormal stop due to an abnormal stop factor that is different from the abnormal stop shown in FIG. When the abnormal stop information analysis unit 13 determines that these are abnormal stops due to separate abnormal stop causes, a new record is created in the abnormal stop information totaling table 31 and is indicated in the abnormal stop information 28. The information is added as separate abnormal stop total information.

  Then, the updated abnormal stop information totaling table 31 is recorded in the record 14.

  By updating the abnormal stop totaling table 31 as described above, the abnormal stop totaling table 31 is recorded with abnormal stops caused by different abnormal stop factors. Further, when there are a plurality of abnormal stops due to the same abnormal stop factor, the abnormal code related to the abnormal stop factor recognized by the automatic driving device at the first abnormal stop is recorded in the abnormal code 34 of the abnormal stop total table 31. . For this reason, it is necessary to take countermeasures even if the cause of the abnormal stop that occurred during automatic operation of the equipment differs from the cause of the abnormal stop when the trial operation is performed by taking measures against the generated abnormality. Only the former abnormal stop factor is recorded.

  After updating the abnormal stop information totaling table 31 described above, the value of the stop flag 27 is determined in the latest abnormal stop information 28 acquired from the abnormal stop history table 21. The stop flag 27 indicates whether or not an abnormal stop that has already occurred and is recorded in the abnormal stop information totaling table 31 is related to the abnormal stop indicated in the abnormal stop information 28. When it is determined that the abnormal stop information 28 is caused by the same abnormal stop cause as the abnormal stop shown in the abnormal stop total information 37, the stop flag 27 is 1, while the abnormal stop information 28 is the abnormal stop total. When it is determined that it is caused by an abnormal stop factor that is different from the abnormal stop shown in the information 37, the stop flag 27 becomes 0. In this way, by checking the value of the stop flag 27, the abnormal stop history table 21 also shows abnormal stop information that occurred during operation of the equipment, and abnormalities when the trial operation was performed by taking measures against the generated abnormality. A stop can be distinguished.

  Moreover, the equipment abnormal stop cancellation delay time td is, for example, when an abnormality occurs in each automatic driving device and the operation is stopped until the equipment manager removes a factor that can be considered as the cause of the abnormality and restarts the operation. For example, a value of about several seconds to one hour is set. As another example, the equipment abnormal stop cancellation delay time td is determined in advance based on the cycle time of the production equipment to be managed. For example, when the cycle time from part introduction to finished product discharge is 1 minute in the entire production facility, the equipment abnormal stop cancellation delay time td is set to 1 minute. Also, a numerical value determined by multiplying the cycle time by a certain factor, for example, for equipment with a cycle time of 1 minute, it is set to 30 seconds that is half the cycle time, or 2 minutes that is twice the cycle time. It may be set.

  Moreover, you may set the equipment abnormal stop cancellation | release delay time td for every automatic operation apparatus 2-6. Furthermore, the equipment abnormal stop cancellation delay time td may be set for each abnormal stop factor.

  In this case, the recording unit 14 records a correspondence table between the device ID 33 and the abnormality code 34 of the automatic driving device and the equipment abnormal stop cancellation delay time td. And the abnormal stop information analysis part 13 will acquire apparatus ID33 and the abnormal code 34 from the abnormal stop total information 37, if the abnormal stop total information 37 is acquired, an equipment abnormal stop cancellation | release delay time with reference to said correspondence table td is determined.

  In this way, by optimizing the equipment abnormal stop cancellation delay time td for each condition, it is possible to determine whether multiple abnormal stops are caused by the same abnormal stop factor or different abnormal stop factors. It can be determined accurately.

  This state will be described with reference to a timing chart of the automatic driving apparatus that has caused an abnormal stop. FIG. 4 shows a timing chart of the automatic driving apparatus that has caused an abnormal stop.

  In FIG. 4, a line 101 indicates whether or not automatic operation is in progress. When the vehicle is in the upper ON position, the automatic operation is in progress, and when it is in the lower OFF position, the vehicle is stopped. A line 102 indicates whether or not the automatic driving device has detected an abnormality. When the automatic driving device is in the upper position, the line 102 indicates a state in which the automatic driving device detects an abnormality and transmits an abnormal code. Is in the OFF position, it means that the automatic driving apparatus determines that the apparatus state is normal.

  First, when the automatic driving apparatus detects an abnormality at timing 120, it starts to send an abnormality code corresponding to the cause of the abnormality to the facility operation management apparatus 1. Thereafter, at timing 121, the automatic driving apparatus stops. This timing 121 is the first abnormal stop start time.

  Thereafter, the cause of the abnormal stop is removed, and automatic operation is restarted on a trial basis at timing 122. This timing 122 becomes the first abnormal stop end time.

  Thereafter, the automatic driving apparatus detects an abnormality again and starts to transmit an abnormal code, and at the timing 123, the automatic driving apparatus abnormally stops. This timing 123 becomes the second abnormal stop start time. When the automatic operation is resumed again at the timing 124, the timing 124 becomes the second abnormal stop end time.

  At this time, the abnormal stop 151 from the first abnormal stop start time to the first abnormal stop end time and the abnormal stop 152 from the second abnormal stop start time to the second abnormal stop end time are the equipment operation It is recorded as a separate abnormal stop in the abnormal stop history table 21 of the management apparatus 1. On the other hand, the first abnormal stop release time tr1 is set by adding the abnormal stop release delay time td to the first abnormal stop end time. Since the second abnormal stop start time is earlier than the first abnormal stop release time tr1, it is recorded as an abnormal stop due to the same factor in the abnormal stop count table 31 of the equipment operation management device 1. . At this time, in the abnormal stop total information, the period of the abnormal stop start time as the timing 121 and the abnormal stop end time as the timing 124 shown in the line 161 is recorded as an abnormal stop.

  After that, when the automatic driving device stops abnormally for the third time at timing 125 and restarts operation at timing 126, the abnormal stop start time (timing 125) of this third abnormal stop period 153 and the abnormal stop release at timing 124 The second abnormal stop cancellation time tr2 added with the delay time td is compared. Since the timing 125 is earlier than the second abnormal stop cancellation time tr2, the third abnormal stop 153 starting at the timing 125 is also regarded as an abnormal stop caused by the same abnormal stop factor in the abnormal stop count table 31. In the abnormal stop total information recorded, the abnormal stop end time is rewritten to the timing 126, and the period 162 in which the abnormal stop start time is the timing 121 and the abnormal stop end time is the timing 126 is recorded as an abnormal stop.

  In this way, it is possible to determine that abnormal stops that are repeated within a certain period are all abnormal stops due to the same abnormal stop factor.

  Up to now, the abnormal stop information analysis unit 13 introduces the concept of abnormal stop cancellation delay time td, so that the abnormal stop that is repeated within a short time for the same automatic driving device is caused by the same abnormal stop factor. It has been described as determining. However, the configuration of the abnormal stop information analysis unit 13 is not limited to this. For example, before receiving the device status information indicating that it has been operating normally for a certain period of time from another automatic driving device that follows on the production line 7 rather than the automatic driving device that caused the abnormal stop, the abnormal stop is again performed. If an error occurs, the abnormal stop that occurred first and the abnormal stop that occurred again may be totaled as an abnormal stop due to the same abnormal stop factor, and recorded in the abnormal stop total table 31 as described above. In addition, as the fixed period in this case, it is possible to use an empirically determined time such as several seconds to 1 hour, or a time until a predetermined number of workpieces pass at a certain point on the production line 7. .

  Next, the operation procedure of the facility operation management apparatus 1 according to an example of the present invention will be described with reference to the flowchart shown in FIG.

  First, the operation information input unit 11 receives the device state information transmitted from each of the automatic driving devices 2 to 6 under management (step 51).

  The received device status information is sent to the control unit 10. When the control unit 10 receives the device state information and detects the occurrence of an abnormal stop with reference to the device state flag, the abnormal stop information extraction unit 12 reads the abnormal stop history table 21 from the recording unit 14 and detects the abnormal stop. Information relating to the abnormal stop is extracted from the apparatus status information and added to the history table 21 (step 52).

  Thereafter, when the information on the resumption of operation is obtained from the automatic driving device that has transmitted the device state information indicating that the abnormal stop has occurred, and the abnormal stop period is determined, the abnormal stop information analysis unit 13 of the control unit 10 14, the abnormal stop history table 21 and the abnormal stop count table 31 are read out. And the automatic driving | operation apparatus shown by the newest abnormal stop information 28 added to the abnormal stop history table 21 is specified, and the abnormal stop total information 37 regarding the apparatus is extracted from the abnormal stop total table 31 (step 53). .

  Next, the abnormal stop information analysis unit 13 determines an abnormal stop cancellation delay time td (step 54). At that time, the abnormal stop cancellation delay time td may be determined based on the device ID 33 of the automatic driving device or the device ID 33 and the abnormal code 34.

  When the abnormal stop release delay time td is determined, the abnormal stop calculated by adding the abnormal stop release delay time td to the abnormal stop end time 36 indicated in the abnormal stop total information 37 extracted from the abnormal stop total table 31. A release time tr is set. Then, the abnormal stop release time tr is compared with the abnormal stop start time 25 of the latest abnormal stop information 28 added to the abnormal stop history table 21 (step 55).

  If the abnormal stop start time 25 is earlier than the abnormal stop release time tr as a result of the comparison, the abnormal stop end time 36 of the abnormal stop total information 37 is added to the abnormal stop history table 21 and the latest abnormality is added. The abnormal stop count table 31 is updated by rewriting the abnormal stop time 26 in the stop information 28 (step 56).

  On the other hand, if the abnormal stop release time tr is earlier than or the same as the abnormal stop start time 25, a new record is created in the abnormal stop count table 31, and the latest abnormal stop information 28 is added to the new abnormality. It adds as stop total information (step 57).

  As described above, the facility operation management device 1 according to an example of the present invention records an abnormal stop that has occurred in a managed automatic driving device. In addition, the facility operation management device 1 uses the same abnormal stop cause as an abnormal stop that occurred before that in the automatic operation device that resumed operation after returning from the abnormal stop. Aggregate as an abnormal stop. Therefore, even if the equipment administrator removes the abnormal stop factor of the automatic operation device and performs a trial operation, and the abnormal operation is stopped again with a separate abnormal stop factor in the trial operation, the trial operation is the same as the first abnormal stop. It can be counted as an abnormal stop factor. Therefore, since abnormal stop information can be collected and recorded in a form closer to the actual situation, it is easy to take measures without taking measures against abnormal stop of the automatic driving device.

  The equipment operation management device according to the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the facility operation management device is described as managing the operation status of the automatic operation device used in the production facility. However, the facility operation management device according to the present invention is a packaging facility or a delivery device. It can also be used for other sorting equipment.

  In the above embodiment, the facility operation management apparatus uses a personal computer as a component. However, when the scale of the facility to be managed is large and hardware with higher processing capacity is required, Instead, a workstation or a large computer may be used, or a dedicated hardware may be produced and used using a commercially available computing device or memory.

  Furthermore, in the above embodiment, the facility operation management device is configured to manage one production facility, but a plurality of production facilities may be managed by one facility operation management device. In addition, instead of connecting all the automatic operation devices of the production facility to one network, it is divided into a plurality of segments, and one to a plurality of automatic operation devices are connected to each segment to increase the network responsiveness. Also good.

  The recording unit of the facility operation management apparatus may be configured by a file server that can communicate with the facility operation management apparatus via a network.

  As described above, the facility operation management apparatus according to the present invention can be appropriately optimized within the scope of the present invention in accordance with the configuration of the facility to be managed.
