FIG. 2 shows a functional block diagram of a method for displaying the inspection guide of the equipment. Equipment inspection is for equipment 10
When the operation time of a predetermined inspection cycle has passed since the completion date of the previous equipment inspection, the operation is periodically performed for each inspection item. Here, the operation time of the facility 10 is defined as the time from the start of the facility where the main power is turned on to the stop of the facility where the main power is shut off. The inspection information storage means 21 stores the equipment inspection data input by the setting input means 40 so that the equipment inspection is performed at a predetermined inspection cycle for each inspection item.

The elapsed time calculating means 22 is provided in the equipment 10
The operation time during which the vehicle has been operated is measured at predetermined time intervals, and based on the operation time, the elapsed inspection time is accumulated for each of the inspection items updated and stored as the latest data and stored. Here, the inspection elapsed time represents the total of the operation time since the previous inspection completion, and the operation time is the time from the time when the main power is turned on to the time when the main power is turned off, as described above. I do. This inspection elapsed time data is automatically updated to zero when information on the completion of inspection for each inspection item of the facility 10 is input by an operator using an operation button or the like provided on the operation instruction means 30.
Thereafter, the inspection elapsed time data is accumulated as described above until information on the completion of the next inspection is input.

The inspection margin time calculating means 23 calculates the difference between the inspection cycle data stored in the inspection information storing means 21 and the inspection elapsed time stored by the elapsed time calculating means 22, ie, the next time. Calculate the margin time until equipment inspection. Then, the calculated margin time is input to the guidance display determination means 24. The guidance display determining means 24 instructs the equipment inspection when the margin time before the equipment inspection is smaller than a predetermined time set in advance, that is, when the inspection time of the equipment approaches and reaches a predetermined time before the scheduled inspection date. The inspection information is displayed on the display device 50. At this time, a new screen (pop-up window) is automatically superimposed on the screen of the display device 50 on which information such as other driving conditions is already displayed. As a display method at this time, first, a message instructing the equipment inspection is displayed, and then, as the detailed contents of the inspection, information on each inspection item may be displayed on another screen. A predetermined number of items may be collectively displayed on the same screen as the message, or detailed information may be displayed for each inspection item.

The message for instructing equipment inspection displayed as described above is displayed such that the pop-up window is closed and disappears when the operator displays operating information for operating the equipment 10 on the same display device 50. Has become. However, when a predetermined time, for example, one hour, elapses after the disappearance of the instruction message, the guidance display determination means 24 again displays a message for instructing the equipment inspection. In this way, when the equipment inspection instruction message is erased from the screen of the display device 50, it is repeatedly displayed every time a predetermined time elapses, and this display is repeated by the operation instruction means 30 when the inspection is completed. Continue until information is entered. Further, when the inspection item of the facility 10 reaches the scheduled inspection date, the guidance display determination means 24 displays that the inspection date has been reached in a pop-up window. At this time, the display of the inspection information may be such that the color of the display and the inspection information of the inspection item that has not reached the inspection date may be changed, or the luminance of the display may be changed.

FIG. 3 shows a flowchart of a method for displaying the inspection guide of the equipment. When operating the equipment 10, first, in step S1, the equipment 10 is started, that is, the control device 20 is started. At this time, in step S2, the guidance display determination means 24 of the control device 20
For each of the inspection items, it is determined whether or not inspection information is displayed on the display device 50 as a message instructing an equipment inspection. That is, the guidance display determination means 24
Inputs the time data until the next equipment inspection, which is obtained by the inspection margin time calculating means 23 as the difference between the inspection cycle data and the inspection elapsed time for each inspection item. Then, the guidance display determination means 24 determines whether the time until the next facility inspection is shorter than the predetermined time for setting the display time of the inspection information for each inspection item. If it is also smaller, the process proceeds to step S3, and if it is longer than a predetermined time, step S6 is executed.

In step S3, the guidance display determination means 24 displays the inspection information of the equipment 10 for the corresponding inspection item in a pop-up window of the display device 50. Further, the guidance display determination means 24 displays the inspection items at predetermined time intervals not only at the time of starting the equipment but also during the operation of the equipment. The content of the displayed inspection information may be an instruction message indicating that the inspection is required within a predetermined time or within a predetermined number of days, or an inspection item or inspection schedule in which a predetermined number is displayed on one screen as shown in FIG. A list of days, a diagram showing one inspection item and the inspection site of this inspection item, and information for inspection support such as a past inspection history of this inspection item are used. In step S4, it is determined whether or not the information of the completion of the check has been input from the operation instructing means 30 for the check item. Update the elapsed time to zero. If the information of the completion of the inspection is not input in step S4, the process proceeds to step S6.

In addition, during steps S2 to S5, the equipment 1
0 indicates that the vehicle is in operation, and the inspection information displayed in the pop-up window of the display device 50 is erased by the operation of the operator as needed, or is continuously displayed as it is. Next, in step S6, the elapsed time calculation means 22 measures the operation time of the facility 10 at predetermined time intervals, accumulates this operation time in the inspection elapsed time stored as the latest data, and sets a new inspection elapsed time. The time, that is, the cumulative elapsed inspection time since the previous inspection was completed is updated and stored. In the next step S7, the inspection allowance time calculating means 23 checks the inspection cycle data stored in the inspection information storage means 21 and the elapsed time calculating means 2
The difference from the inspection elapsed time stored in step 2, ie, the time until the next equipment inspection is obtained. The time required for the next facility inspection is determined by the guidance display determining means 24.
And the step S2 is executed.

As described above, the inspection information is displayed to the operator in the pop-up window of the display device 50 at a predetermined time before the scheduled inspection date of the facility 10, and further, at a predetermined time interval until the inspection is completed. It is displayed repeatedly every time. Further, the display frequency may be increased according to the importance of the inspection items, and the inspection information may be reliably notified by a method such as displaying a warning if any inspection item has passed the scheduled inspection date. .

In this way, since the inspection information can be known in advance, the inspection work can be performed systematically while adjusting the operation time of the equipment. In addition, the inspection time can be estimated from the list of inspection items, and an operation plan can be made in consideration of the inspection time, so that the inspection can be performed as planned. Further, since the operator is alerted until the equipment inspection is completed, the inspection can be reliably performed. Further, on a separate screen, detailed information such as the details of treatment based on the inspection, or information missing on the message screen, for example, an inspection work procedure, may be supplemented. Thus, necessary information can be obtained each time the inspection work is required, so that the operator can easily and efficiently perform the inspection work.

Further, depending on each inspection item, the inspection cycle may be in days, weeks, or months. In addition, the inspection cycle time is the operation time of the equipment 10, but may be all elapsed time including the suspension of the equipment 10 depending on the inspection item. In this way, the inspection cycle data can be managed on an hourly or monthly basis according to the importance of each inspection item, and can be managed on calendar days in addition to operating hours, simplifying data management. it can. The scheduled inspection date may be input in advance as date data for a predetermined period, for example, one year. Accordingly, for the inspection items whose inspection cycle is shortened or changed with the lapse of time, the inspection cycle data is not changed every time the inspection is completed, so that data management becomes easy.

When a predetermined time comes before a scheduled equipment inspection date, inspection information is displayed in a pop-up window. The predetermined time may be a uniform time regardless of the inspection item, or may be different for each inspection item. Each may be set.
Accordingly, when there is a replacement member such as a consumable that requires replacement at the time of equipment inspection and takes a long time to arrange, by displaying an instruction to arrange the replacement member together with the inspection information in a pop-up window, Delivery time management from arrangement of replacement parts to procurement can be enhanced. Further, regarding the inspection information displayed during the operation of the equipment, the interval of the display time may be set for each inspection item. As a result, the display interval of important inspection items can be shortened, so that the operator can be alerted frequently.

If the equipment inspection has not been completed even after the inspection date, that is, if the information of the completion of the inspection has not been input, the inspection items of the equipment 10 are further noticeable.
For example, a warning may be given, such as blinking a pop-up window, or keeping the displayed pop-up window from disappearing unless a special operation is performed. In this way, the operator can be alerted to ensure that the equipment inspection is performed.

In this manner, the inspection information such as the inspection items of the equipment 10 is always notified to the operator before the scheduled inspection date, and the display frequency is increased as the scheduled inspection time approaches, and the inspection schedule is further increased. If the inspection is not completed even after the time has passed, a warning is displayed and the like, so that the operator can enhance the management of the inspection work and can easily perform the inspection work. As a result, the equipment inspection is performed reliably, the deterioration of the processing accuracy due to the deterioration or aging of the equipment 10 can be prevented, and the life of the equipment 10 can be improved.
