Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring / maintenance system, and more particularly to a remote monitoring / maintenance system capable of improving the efficiency of maintenance work.

[0002]

2. Description of the Related Art Devices such as cranes and heat exchangers are not mass-produced products, unlike general consumer goods. Even if there is a basic design, it is generally designed individually according to the customer's request. In order to fulfill those needs, complex mechanisms are incorporated into the basic design. In addition, when such a device is installed, the function of the device is often added or changed.

Control of such equipment is often realized by software. Therefore, when a failure occurs in the device, it is becoming difficult for the user of the device to independently find and repair the failure point. When an equipment failure is detected, in the case of a simple failure, the equipment administrator can perform repairs through a telephone conversation with the maintenance center, but if the failure situation is complex, the maintenance An expert will be there to repair it.

For example, conventionally, in order to perform maintenance of equipment such as a harbor crane, a monitoring device is provided at a place apart from the crane together with a control device for the crane. When the monitoring device detects that a failure has occurred in the equipment, the administrator of the equipment requests the maintenance center for repair, and a maintenance expert is sent to repair the equipment. If an expert visits and repairs, maintenance will be very expensive.

Further, in order to identify a faulty part at the time of repair, it is necessary to grasp the state of the equipment by various measuring instruments, but it is difficult to prepare various measuring instruments at the installation site of the equipment. is there. Therefore, it is common to actually operate the device and estimate the failure point from the state at that time. As such, repairs often require experience and tend to lack specialists.

Further, as described above, since the devices are often designed individually, it is difficult for even a maintenance expert to repair them unless there is information about the mechanism added to the basic design or the changed function. There are some cases. In that case, the developer / designer of the device is forced to go to repair. Therefore, the response to the obstacle may be delayed.

Further, conventionally, the operation / maintenance manual is distributed to customers as a printed matter. As the mechanism of the device becomes more complicated, the amount of manuals will become huge, and it will be difficult to find the manual part related to the failure.
In the case of multiple failures, repairs will be carried out with reference to many manuals. Therefore, the time required for recovery tends to be long.

Even if the location of the failure can be identified, repair cannot be performed without maintenance parts. Therefore, there is no problem if the customer has all the maintenance parts, but it is expensive to run the equipment if all the maintenance parts are prepared. Further, when a failure occurs in the individually designed mechanism, it is difficult to procure the parts. However, the parts may be located elsewhere. In such a case, if parts are interchanged, the stock of maintenance parts can be reduced. As a result, running costs can be reduced.

Written to 2. Further, the operation command and the state data are sent to the operation state display control unit 114-14. The operation state display control unit 114-14 controls the display unit 108 to display the operation command and the state data (step S15).

Next, the monitoring section 114-26 sends the status data to the failure occurrence processing section 114-18. The failure occurrence processing unit 114-18 determines each of the status data and the current reference data 1
Compare with the corresponding reference value of 14-16. If the state data is within the range of the standard value of the corresponding current standard data,
No special processing is performed assuming that there is no obstacle. When no fault has occurred, the above operation is repeated.

If any of the status data is out of the range of the current reference data, the failure occurrence processing section 116-
18 detects the occurrence of a failure (Yes in step S20).
s). At the same time, a recording stop instruction is issued to the operation data recording unit 112.
And the operation of writing the operation data to the operation data recording unit 112 is stopped. In addition, the occurrence of failure is displayed on the display unit 1.
It is displayed on 08 and informs the remote side engineer. Also,
The failure occurrence processing unit 114-18 notifies the recovery guidance processing unit 114-10 of the occurrence of a failure. The restoration guidance processing unit 114-10 identifies the corresponding portion of the restoration guidance 110-6 based on the location of the failure.

The remote engineer side engineer who knows the occurrence of the failure from the display on the display unit 108 operates the input unit 104 to
Create a failure notification that notifies you of a failure. At this time, the failure occurrence processing unit 114-18 reads out the operation data from the operation data recording unit 112, and also reads out the part of the recovery guidance specified by the recovery guidance processing unit 114-10 from the recovery guidance 110-6 and creates it. The read operation data and the restoration guidance section are transmitted to the center device 50 via the communication section 120 together with the failure notification (step S22).

In the above, when the failure occurrence notification is transmitted from the remote machine 40 to the center machine 50, the center machine 50 may be busy or unusable. At this time, when the failure occurrence processing unit 114-18 determines that the failure occurrence notification is not received by the center device 50 (step S24), it extracts the telephone number of the FAX 54 of the center side system 4 from the customer data 110-2, and the failure occurs. FAX only via the communication unit 120
It transmits to 54 (step S26).

The engineer on the side of the center machine sees the fault occurrence notification received by the FAX 54 and contacts the remote machine 40 when the center machine 50 becomes available. At this time, the entire customer data 132-2 is read from the storage unit 132 in response to the input from the input unit 136,
It is displayed on the display unit 140. The engineer on the center machine side extracts the telephone number of the remote machine 40 from the displayed total customer data and calls the remote machine 40 via the communication unit 142. Thus, as described below, the repair work is performed using the transmitted restoration guidance (step S
28). In response to the call from the center machine 50, the remote machine 40 transmits a failure occurrence notification, operation data, and restoration guide dice to the center machine 50 via the communication unit 120.

The processing unit 134 of the center machine 50 receives the failure occurrence notification via the communication unit 142. Processing unit 134
Responds to the reception of the failure occurrence notification, automatically receives the operation data and the recovery guidance unit, and automatically stores them in the storage unit 132. At the same time, the processing unit 134 automatically displays at least one of the operation data and the recovery guidance unit on the display unit 140. The engineer on the side of the center machine starts the failure recovery work from the displayed failure status or operation data. The engineer on the center machine side
The recovery work is instructed via the microphone 144.

The remote engineer opens a specific portion of the restoration guidance according to the voice instruction from the center engineer. In this way, the remote side engineer and the center side engineer can perform repairs while having a dialogue based on the recovery guidance of the same content.

In this example, in response to the reception of the failure occurrence notification, at least one of the operation data and the recovery guidance section of the display section 140 is automatically displayed. However, the center side engineer inputs a display instruction. However, in response to this, at least one of the operation data and the recovery guidance section and the display section 140 may be displayed. In addition, recovery guidance may be displayed, in which operation data may be displayed.

The technician on the remote side gives an instruction to another technician to photograph a specific portion with the camera 32, if necessary. The captured image is displayed on the display unit 1 of the remote device 40.
08 is displayed. This image is simultaneously sent to the center device 50 via the communication unit 120. The processing unit 134 of the center device 50 receives the image via the communication unit 142 and displays the image on the display unit 140. In this way, the engineer on the center machine side confirms the image. When another image is needed, the microphone 144 and the speaker 146 of the center unit 50 are used.
The technician on the center machine side and the technician on the camera side talk with each other through the microphone 34 and the speaker 36 on the remote machine side to photograph another place. At this time, the remote side engineer can hear the conversation between the center side engineer and the control room side engineer. If necessary, they can participate in the conversation.

In the mobile phone of this embodiment, the image data and the audio data are transmitted online, but they may be transmitted as files offline. The offline communication function is convenient when the crane cannot directly connect to the public line. When a mobile phone (PHS) is used as the communication unit 120 and the file size becomes large,
Since there is a high possibility that the line will be disconnected on the way, it is desirable to communicate in smaller size units for compression when transmitting an image.

When it is judged that the parts need to be replaced for repairing the trouble, the engineer on the center machine side instructs the engineer on the remote side to replace the parts. The remote engineer reads out the maintenance parts list 110-6 from the storage unit 110 and displays it on the display unit 108. In this way, the stock of maintenance parts is confirmed and repairs are performed. Replacement parts are maintenance parts list 110
If it is not found in -6, the remote side engineer contacts the center side engineer. The engineer on the side of the center machine reads out the entire maintenance parts data 132-8 from the storage unit 132 and causes the display unit 140 to display the data. Overall maintenance parts data 1
32-8 centrally stores the parts list in stock at the service station or other customers.
Check the inventory of necessary parts by looking at -8. If replacement parts exist at the service station or at another customer location, inform the remote technician of their location. Thus, the remote technician can obtain replacement parts and perform repairs.

In this way, it is sufficient for the customer to have temporary maintenance parts in stock. Even if you do not have all the maintenance parts in stock, you can reduce the inventory of maintenance parts by shortening the downtime of cranes by exchanging maintenance parts with service stations or other customers. You can

When the repair is completed, the flow shown in FIG. 6 is executed.

When the repair is completed, the remote engineer gives an instruction through the input unit 104 to create an inspection / repair report.
Form processing unit 114-8 of the processing unit 114 of the remote machine 40
Reads out the inspection and repair form form from the form form data 110-10 in the storage unit 110 and displays it on the display unit 108 (step S92). The remote engineer inputs necessary information such as date of repair, model to be repaired, failure status, repair contents, and replacement parts in the inspection and repair form form displayed from the input unit 104 (step S94). When the input is completed, the form processing unit 114-8 sends the completed inspection / repair form to the output unit 106 to print the inspection / repair form (step S96). Further, the form processing unit 114-8 updates the maintenance parts list 110-6 based on the input used replacement parts (S98). That is, the stock number of used replacement parts is reduced. At the same time, the form processing unit 114-8 updates the inspection and repair history data 110-12 based on the input contents (step S100).
In this way, the inspection / repair history data 110-12 holds the history of past inspection / repair.

Further, the form processing unit 114-8 transmits the inspection and repair form to the center unit 50 via the communication unit 120 (step S102). In the center machine 50, the communication unit 1
When the inspection and repair report is received via 42, the processing unit 13
4 is the entire inspection / repair history data 1 in the same manner as described above based on the received inspection / repair form and the sender customer data.
32-8 and the general maintenance parts list 132-6 are updated.
Thus, the remote machine 40 and the center machine 50 store the latest whole inspection and repair history data 132-8 and the whole maintenance parts list 132-6.

When the maintenance parts are newly prepared at the customer site, the remote engineer gives an instruction from the input unit 104 to update the maintenance parts list. In response to this instruction, the maintenance component processing unit 114-6 of the processing unit 114 reads out the maintenance component list 110-4 and displays it on the display unit 108. The remote engineer inputs from the input unit 104 and updates the maintenance parts list 110-4. In this case, the maintenance parts list 110-4 is automatically updated at the same time as the center device 5 is updated.
However, it may be read by the center device 50 later.

When the remote engineer is informed that there is a ship entry, the remote engineer instructs the input section 104 to create a cargo handling form. In response to this instruction, the operation data processing unit 114
-4 reads the form data 110-10,
The cargo handling schedule form is displayed on the display unit 108. The remote engineer inputs various data from the input unit 104 into the cargo handling schedule form. For example, the scheduled mooring date / time, the scheduled departure date / time, the loading / unloading container amount, the loading container amount, and the like.
When the input is completed, the operation data processing unit 114-4 sends the input cargo handling schedule form to the output unit 106 and prints the cargo handling schedule form. In addition, the cargo handling schedule form is used as operating data 11
0-4 is stored in the storage unit. In this case, the operation data 110-4 is automatically updated at the same time when it is updated.
However, the information may be read by the center device 50 later.

Operation data processing unit 114 of processing unit 114-
4 reads the operation data 110-4 and displays it on the display unit 108 in response to the operation data display instruction from the input unit 104. That is, the number of handled containers is displayed by day / month / year by a numerical value or a graph. Further, in the graph display, it is possible to display by weight and by time.

Next, the operation of the remote monitoring and maintenance system of the present invention will be further described with reference to FIG.

The engineer on the center side inputs various instructions from the input unit 136. These instructions are sent to the center machine 50.
The remote unit 4 via the processing unit 134 and the communication unit 142 of
Sent to 0. The instruction is the communication unit 12 of the remote machine 40.
It is received by the processing unit 114 via 0. Processing unit 11
4 determines whether the received instruction is a customer data update instruction (step S52). When the instruction is to update the customer data, the customer data processing unit 114-2 of the processing unit 114 is activated. Customer data processing unit 114
-2 reads the customer data, updates the customer data based on the received content, and stores it again in the storage unit 110 (step S54).

When the received instruction is not the customer data update instruction, it is determined whether it is an operation (cargo handling) data transmission instruction (step S56). When the transmitted instruction is a cargo handling data transmission instruction, the processing unit 114
Activates the operation data processing unit 114-4. The operation data processing unit 114-4 stores the operation data 1 from the storage unit 110.
10-4 is read and transmitted to the center device 50 via the communication unit 120 (step S58). The processing unit 134 of the remote machine 50 sends the cargo handling data 11 via the communication unit 142.
When 0-4 is received, the entire cargo handling history data 132-4 is read from the storage unit 132, and the received cargo handling data 11
The entire cargo handling history data 132-4 is updated based on 0-4.

In the center machine 50, the engineer on the center machine side later inputs an inspection plan preparation instruction from the input unit 136. In response to this instruction, the processing unit 134 causes the storage unit 13 to
The entire cargo handling history data 132-4 and the overall inspection / repair history data 132-8 are read from No. 2. When the customer name, the device name, and the device number are specified from the input unit 136, the processing unit 134 of the remote machine 50 stores the customer name, the device installed at the customer's destination, and the cargo handling history data related to the device number. Estimate the remaining life of each part of the equipment from inspection and repair history data. The center side engineer can determine the next inspection time based on this estimation result and the engineer's schedule.
In this way, the inspection time can be determined with a margin.

Further, the engineer on the side of the center machine outputs an instruction to update the reference data list to the remote machine 40, if necessary, based on the estimation result. Further, the center engineer side engineer reads out the entire maintenance parts data 132-6 from the storage unit 132, and inspects the maintenance parts related to the customer based on the estimated remaining life of each part and the next inspection time. If there is a shortage of maintenance parts, contact the customer, prepare the maintenance parts in advance, and deliver them to the customer.
In this way, the next inspection work can proceed smoothly.

When the received instruction is not the operation data transmission instruction, it is determined whether the reception instruction is the reference data update instruction (step S62). When the received instruction is an instruction to update the reference data, the processing unit 11
4 stores the current reference data 114-16 in the reference data list 110-14. The processing unit 114 then stores the received reference data as the current reference data 114-16 of the processing unit 114.

This is because it may be necessary to change the reference data when the next inspection time is determined. In some cases, it may be necessary to change the reference data on a test basis during repair. At this time, the current reference data is changed to the received reference data. In this way, it is possible to detect a failure occurrence based on various criteria instructed by the center machine 50.

When the received instruction is not the reference data list update instruction, it is determined whether or not the received instruction is the restoration guidance update instruction (step S64). When the received instruction is the restoration guidance update instruction, the processing unit 114 determines that the restoration guidance processing unit 114-1.
Start 0. The recovery guidance processing unit 114-10
The received restoration guidance is stored as the restoration guidance 110-8 in the storage unit 110 (step S66).

As described above, in response to the failure occurrence notification,
Repairs will be made based on the restoration guidance sent.
However, the recovery guidance may be difficult to understand, and the mechanism of the crane 10 may be changed during the repair. In such cases, the current recovery guidance will no longer be valid for subsequent repairs. Therefore, the engineer on the center side creates new restoration guidance by using the programming machine 52. The newly created restoration guidance is transmitted from the programming machine 52 to the center machine 50, and is transmitted from the center machine 50 to the remote machine 40 as described above. In this way, both the center device 50 and the remote device 40 can always hold the optimum recovery guidance.

When the received instruction is not the restoration guidance update instruction, it is determined whether the received instruction is a conditional data collection request (step S68). When the received instruction is a conditional data collection request, the processing unit 114 activates the monitoring unit 114-26. The monitoring unit 114-26 uses the processing unit 1 to check the received data collection condition.
It is stored as 14 collection conditions 114-22 (step S70). At the same time, the flag 114-20 is set. As a result, when the data collection conditions are met, the motion data is stored in the motion data recording unit 112.

When the received instruction is not the restoration guidance update instruction, it is determined whether the received instruction is a conditional data collection request (step S68). When the received instruction is a conditional data collection request, the processing unit 114 activates the monitoring unit 114-26. The monitoring unit 114-26 uses the processing unit 1 to check the received data collection condition.
It is stored as 14 collection conditions 114-22 (step S70). At the same time, the flag 114-20 is set. As a result, when the data collection conditions are met, the motion data is stored in the motion data recording unit 112.

In this conditional data collection function, (1)
PLC Conditional data collection (2) Conditional data collection (3)
There is periodic data collection. In the PLC conditional data collection, the PLC 20 needs a buffer memory for data collection. Since the crane that uses the microcomputer system for automatic operation is equipped with a non-volatile memory, it is also possible to realize high-speed data collection. The management tag in the system of the present invention is set to the input / output signal, and the collected signal is recorded and the trigger condition for the collection is set. On / off of digital signal,
It can be set so that the data collection for the specified time is performed even after the condition is satisfied. The data collection cycle is PLC2.
Although it depends on the connection specification with 0, the PLC field bus can collect data in 100 ms.

If the received instruction is not a conditional data collection request, it is determined whether the received instruction is a real-time collection request (step S72). When the received instruction is a real-time collection request, the processing unit 1
14 activates the monitoring unit 114-26. Monitoring unit 114
-26 sets the real time mode to the mode 114-24 (step S74).

The real-time signal display function is used for real-time confirmation of adjustment support and faulty operation. Basically, it is a function in which the recording function of the operation data in the operation data recording unit 112 from the periodic data collection function is omitted. The data collection cycle is PL
By using fieldbus for C20 communication, 10
A cycle of 0 ms has been realized.

If the received instruction is not a real-time collection request, it is determined whether the received instruction is a parameter setting request (step S76). When the received instruction is a parameter setting request, the parameter setting request is transmitted to the PLC via the communication unit 116 and stored in the parameter 126-2 of the control unit 124-1 (step S78). Each control unit in the control unit 124-1 changes the control value depending on the parameter to control each unit of the crane 10. As a result, the crane 10 can be drive-controlled in various states, and the operation of the crane when a failure occurs can be checked in any state. In addition, the parameters at that time can be set from the side of the center device 50.

Next, a second embodiment of the remote monitoring and maintenance system of the present invention will be described.

In the remote monitoring and maintenance system according to the first embodiment, the restoration guidance itself is transmitted from the remote machine 40 to the center machine 50 together with the failure occurrence notification. However, in the remote monitoring and maintenance system of the second embodiment, when the occurrence of a failure is detected, the data designating the customer, the data designating the device 10, and the recovery guidance specifying data including the version are regarded as the operation data. It is transmitted from the remote device 40 to the center device 50 together with the failure occurrence notification. In the center machine 50, the one corresponding to the recovery guidance specifying data transmitted from the remote machine 40 is read from the entire recovery guidance 132-10 of the storage section 132 and displayed on the display section 40. In this manner, the center-side system engineer and the remote-side system engineer cooperate to repair the failure of the device 10 according to the recovery guidance of the same content.

Here, when the content of the recovery guidance is updated by the programming machine 52, the center machine 50 updates the version and stores it in the overall recovery guidance 132-10 of the storage unit 132. Also, the center machine 5
0 transmits the updated recovery guidance to the remote machine 40 together with the recovery guidance specifying data for specifying the updated recovery guidance. The recovery guidance processing unit 114-10 of the remote machine 40 stores the received recovery guidance and the recovery guidance specifying data in the recovery guidance 110-8 of the storage unit 110. When a failure is detected, the recovery guidance processing unit 114-10 causes the recovery guidance 110 to be transmitted together with the failure occurrence notification.
Read the recovery guidance specific data from -8.

The rest of the configuration and operation are the same as in the first embodiment, so a description thereof will be omitted.

[0107]

As described above, according to the remote monitoring and maintenance system of the present invention, the technician on the remote side and the technician on the center side can efficiently perform repairs according to the same restoration guidance. Further, it is possible to reliably notify the occurrence of a failure from the remote side to the center side.

Further, the form for repair / inspection can be printed on the remote side, and the repair history data on the center side can be automatically updated in response to the input on the form. Also, the entire maintenance parts list on the center side can be automatically updated. Therefore, the parts can be procured among the distributed customers, and the running cost can be reduced.

Also, when a work plan is drafted and input on the remote side, the operation history data on the center side can be automatically updated. Further, the center side can automatically create an inspection plan from the inspection / repair history data and the operation history data. Therefore, it is possible to reduce sudden failures and improve the operating rate of the device.

Further, the acquisition condition of the operation data of the equipment can be set from the remote side or from the center side. Particularly, the operation data of the device can be transmitted from the remote side to the center side in real time. As a result, even when a failure with poor reproducibility occurs, the cause of the failure can be more reliably identified than in the past.
