Description

  The present invention relates to a facility management system and a facility management method for preventing an inspection omission when performing an inspection according to a maintenance inspection plan determined for each facility.

  Conventionally, various maintenance inspections such as an elevator apparatus are periodically performed according to a maintenance inspection plan determined for each facility for maintenance inspections. Specifically, for example, when the maintenance inspection plan corresponding to the elevator apparatus includes four inspection items, that is, safety switch operation inspection, brake torque inspection, chain lubrication, and rail lubrication, These four inspection items must be inspected without omission.

  Here, in order to grasp whether the inspection items included in the maintenance inspection plan are executed without omission, if the worker who possesses the terminal device executes inspections regarding the inspection items included in the maintenance inspection plan, A maintenance inspection management system has been proposed in which an inspection item registered in the terminal device is manually registered as an executed inspection item, and the inspection item registered in the terminal device is notified to an external monitoring center as an operation result (for example, Patent Document 1). reference).

JP 2007-137658 A

  In the conventional system in which the inspection items that have already been executed are manually registered in the terminal device, the operator does not carry out inspections for some of the inspection items included in the maintenance inspection plan. There is a possibility that the item is erroneously registered in the terminal device.

  In such a case, even though an inspection omission has actually occurred, it is registered in the terminal device as having been inspected without omission, so no one notices that an omission has occurred, As a result, inspection omission cannot be prevented. Therefore, in order to prevent an inspection omission, it is assumed that if an inspection omission actually occurs, the inspection omission is detected with high accuracy.

  The present invention has been made in order to solve the above-described problems, and has a simple configuration and accuracy to prevent an inspection omission that may occur when an inspection is performed according to a maintenance inspection plan determined for each facility. The object is to obtain an equipment management system and equipment management method that can be detected well.

In the equipment management system according to the present invention, a maintenance inspection plan for equipment that is a maintenance inspection object is associated with an estimated work time estimated to be required when inspections are performed without omission on inspection items included in the maintenance inspection plan. A storage unit for storing the working time table, an actual working time measuring unit for measuring the actual working time that elapses between the start of execution of inspection according to the maintenance inspection plan and the end of execution, and terminal control for controlling operation The estimated work time corresponding to the current maintenance inspection plan is extracted from the terminal device having a work section and the work time table, and the estimated work time and the current work inspection plan measured by the actual work time measurement section are extracted. by comparing the actual operation time required for, and a determining inspection leak judgment unit whether the inspection leak, the terminal device is operated to begin executing the inspection It is configured so that the power supply is turned on, the terminal control unit and the equipment are connected, and the operation state of the equipment is switched from the normal mode to the maintenance mode. The operation state is switched from the maintenance mode to the normal mode, the connection between the terminal control unit and the equipment is disconnected, and the power is turned off. The actual work time measurement unit is turned on in the terminal device. The time that elapses from when the state is entered until the state is turned off is measured as the actual work time .

  According to the present invention, the actual work time measured as the time elapsed from the start of the inspection to the end of the execution according to the current maintenance inspection plan, and the current maintenance inspection extracted from the work time table. By comparing the estimated work time corresponding to the plan, a configuration for determining whether there is an inspection omission is provided. As a result, it is possible to obtain an equipment management system and equipment management method capable of accurately detecting an inspection omission that may occur when performing an inspection in accordance with a maintenance inspection plan determined for each equipment with a simple configuration. it can.

It is a block diagram which shows the structure of the equipment management system in Embodiment 1 of this invention. It is a flowchart which shows a series of operation | movement of the equipment management system in Embodiment 1 of this invention.

  Hereinafter, the equipment management system by this invention is demonstrated using drawing according to suitable embodiment. Hereinafter, a case where the present invention is applied to an elevator apparatus will be described as an example.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a facility management system according to Embodiment 1 of the present invention. The facility management system in FIG. 1 includes a terminal device 10 owned by an operator who performs maintenance and inspection of an elevator, and an elevator device 20 that is a facility to be subjected to maintenance and inspection.

  Here, in the maintenance and inspection of the elevator apparatus 20, generally, an operator (field engineer) holds the terminal device 10, visits the building where the elevator apparatus 20 in charge is installed, and has a determined maintenance inspection plan. Perform inspection according to In the maintenance inspection of the elevator apparatus 20, a plurality of types of maintenance inspection plans are determined in advance, and the terminal device 10 includes inspection items (that is, work items included in the maintenance inspection plan executed in the current maintenance inspection). The type of inspection that the person should perform this time) is displayed on the screen. The operator must perform inspection without omission on the inspection items displayed on this screen.

  The terminal device 10 includes a terminal control unit 11 and an actual work time measurement unit 12. The elevator apparatus 20 includes an elevator control unit 21, a storage unit 22, an inspection omission determination unit 23, a work time table update unit 24, and a notification unit 25.

  The terminal control unit 11 controls the operation of the terminal device 10. Further, when starting maintenance and inspection of the elevator apparatus 20, the operator operates the terminal apparatus 10 to turn on the terminal apparatus 10 and connect the terminal control unit 11 and the elevator control unit 21. The operation state of the elevator apparatus 20 is switched from the normal mode to the maintenance mode. Thus, when the inspection is being performed by switching to the maintenance mode, the elevator control unit 21 does not notify the external monitoring center that monitors the elevator device 20. Further, the terminal control unit 11 outputs a maintenance inspection plan to be executed in the current maintenance inspection to the elevator control unit 21.

  In addition, since the terminal control unit 11 and the elevator control unit 21 are connected, an inspection (for example, a safety switch operation inspection or a brake torque inspection) that can acquire an electrical signal as performance data from the equipment side has been performed. In this case, an electrical signal corresponding to the type of inspection is input from the elevator control unit 21 to the terminal control unit 11. Further, if an electrical signal is input to the terminal control unit 11, the inspection corresponding to the electrical signal is automatically registered in the terminal device 10 as a completed inspection item. On the other hand, when a manual inspection (for example, lubrication of the chain or lubrication of the rail) is performed, such inspection is manually registered in the terminal device 10 as an performed inspection item.

  Therefore, regarding the inspection items that must be manually registered in the terminal device 10 as described above, the operator mistakenly registers the inspection items in the terminal device 10 as the inspection items that have been performed even though the inspection has not been performed. There is a possibility. In the facility management system according to the first embodiment, it is possible to accurately detect an inspection omission that may occur when such an erroneous registration is performed with a simple configuration.

  Further, if inspections are performed on the inspection items included in the maintenance inspection plan and all the inspection items are registered in the terminal device 10, the maintenance inspection of the elevator apparatus 20 is completed. In this case, the operator operates the terminal device 10 to switch the operation state of the elevator apparatus 20 from the maintenance mode to the normal mode, disconnects the terminal control unit 11 and the elevator control unit 21, and Turn off the power.

  The actual work time measurement unit 12 measures the time that elapses between the start of execution of inspection according to the maintenance inspection plan and the end of execution, and outputs the measurement result to the elevator control unit 21. Note that this elapsed time corresponds to the actual work time required when inspections are performed on the inspection items included in the maintenance inspection plan. Thus, the terminal device 10 automatically transmits the measured actual work time to the elevator device 20.

  Specifically, the actual work time measurement unit 12 measures the time that elapses from when the terminal device 10 is turned on until it is turned off as the actual work time. That is, as described above, the worker turns on the power supply of the terminal device 10 at the start of the maintenance inspection and turns off the power supply at the end of the maintenance inspection. Therefore, it can be said that the elapsed time elapsed from when the power supply of the terminal device 10 is turned on to when it is turned off is equivalent to the actual work time. Note that the actual work time measurement unit 12 may be configured in any manner as long as the actual work time can be measured. For example, the time that elapses between the switch to the maintenance mode and the switch to the normal mode, or the terminal What is necessary is just to comprise so that the time which passes after connecting the control part 11 and the elevator control part 21 until it disconnects may be measured as real work time.

  The elevator control unit 21 controls the operation of the entire elevator. In addition, the elevator control unit 21 acquires the current maintenance inspection plan and the actual work time from the terminal device 10, and outputs the acquisition result to the inspection omission determination unit 23.

  The storage unit 22 is associated with a maintenance inspection plan for equipment that is a maintenance inspection target, and an estimated work time estimated to be required when the inspection items included in the maintenance inspection plan are executed without omission. A time table is stored in advance. The estimated work time may be set in advance according to work conditions (for example, elevator model, car capacity, number of floors of the building in which the elevator is installed, or the technical level of the worker). . Further, the elevator control unit 21 is configured to acquire a work condition corresponding to the worker who possesses it from the terminal device 10 and appropriately change the estimated work time included in the work time table based on the acquired work condition. May be.

  The inspection omission determination unit 23 acquires the current maintenance inspection plan and the actual work time from the elevator control unit 21. Further, the inspection omission determination unit 23 extracts the estimated work time corresponding to the current maintenance check plan from the work time table stored in the storage unit 22, and extracts the estimated work time and the acquired actual work time. To determine whether there is an inspection omission. In other words, if an inspection omission has occurred, the inspection that should have been performed is not actually executed, so the work time is shortened by that amount, and the obtained estimated work time is obtained. Actual work time is shortened. Therefore, the inspection omission determination unit 23 can determine the presence or absence of inspection omission by comparing the extracted estimated work time with the acquired actual work time.

  Specifically, the inspection omission determination unit 23 determines that there is an omission if, for example, the ratio of the acquired actual work time to the extracted estimated work time is less than a preset threshold ratio (for example, about 50%). If it is determined that the ratio is greater than or equal to the threshold ratio, it is determined that there is no inspection omission.

  In this way, by comparing the actual work time acquired from the actual work time measuring unit 12 with the estimated work time extracted from the work time table, it is determined whether there is a check omission, thereby accurately detecting the check omission. Can be detected.

  When the inspection omission determination unit 23 determines that there is no inspection omission, the operation time table update unit 24 acquires the current maintenance inspection plan and the actual operation time from the inspection omission determination unit 23, and uses the acquired actual operation time. The estimated work time corresponding to the current maintenance inspection plan in the work time table stored in the storage unit 22 is updated. Specifically, the work time table update unit 24 calculates, for example, an average value of the estimated work time extracted by the inspection omission determination unit 23 and the acquired actual work time, and performs the current maintenance in the work time table. The estimated work time corresponding to the inspection plan is replaced with the calculated average value and updated. Note that the estimated work time corresponding to the current maintenance inspection plan in the work time table may be updated by directly replacing the acquired actual work time.

  In this way, by updating the estimated work time corresponding to the current maintenance check plan in the work time table based on the actual work time obtained by executing the current maintenance check plan, When the same thing is executed after the next time, the presence or absence of inspection omission can be determined with higher accuracy.

  When the inspection omission determination unit 23 determines that there is an inspection omission, the notification unit 25 notifies that an inspection omission has occurred. Specifically, for example, the notification unit 25 notifies the operator or the administrator who manages the worker on-site that a warning mail is transmitted to notify that there is an inspection failure. In addition, you may comprise so that it may alert | report that there was an inspection omission by sounding an alarm sound or displaying an alarm screen. Further, when the inspection omission determination unit 23 determines that there is an omission in the inspection, the elevator apparatus 20 may be prevented from performing a normal operation, for example, to stop the traveling of the car.

  Thus, when it is determined that there is an inspection omission by the inspection omission determination unit 23, it is possible to make the operator or the administrator aware that there is an omission in inspection by the above-described means. Therefore, it is possible to prevent an inspection omission when the inspection is executed according to the maintenance inspection plan.

  Next, a series of operations of the facility management system according to the first embodiment will be described with reference to the flowchart of FIG. FIG. 2 is a flowchart showing a series of operations of the facility management system according to Embodiment 1 of the present invention.

  In step S <b> 101, the inspection omission determination unit 23 determines whether or not the current maintenance inspection plan and the actual work time are input from the elevator control unit 21. If the inspection omission determination unit 23 determines that the current maintenance inspection plan and the actual work time have been acquired (that is, YES), the process proceeds to step S102. On the other hand, if the inspection omission determination unit 23 determines that the current maintenance inspection plan and the actual work time have not been acquired (that is, NO), the process of step S101 is repeated again. That is, the inspection omission determination unit 23 repeats the process of step S101 until the current maintenance inspection plan and the actual work time are acquired from the elevator control unit 21.

  In step S102, the inspection omission determination unit 23 extracts the estimated work time corresponding to the acquired current maintenance check plan from the work time table stored in the storage unit 22, and proceeds to step S103.

  In step S103, the inspection omission determination unit 23 compares the acquired actual work time with the extracted estimated work time, and proceeds to step S104.

  In step S104, the inspection omission determination unit 23 determines the presence or absence of inspection omission based on the comparison result in step S103. Here, if the inspection omission determination unit 23 determines that there is an inspection omission (that is, YES), the process proceeds to step S105. On the other hand, if the inspection omission determination unit 23 determines that there is no inspection omission (that is, NO), the process proceeds to step S106.

  In step S105, the notification unit 25 notifies that there is an inspection omission and ends a series of processing.

  In step S106, the work time table update unit 24 acquires the current maintenance inspection plan and the actual work time from the inspection omission determination unit 23, and uses the acquired actual work time to store the work stored in the storage unit 22. The estimated work time corresponding to the current maintenance inspection plan in the time table is updated, and the series of processes is terminated.

  As described above, according to the first embodiment, the actual work time measured as the time elapsed from the start of the inspection to the end of the execution according to the current maintenance inspection plan is extracted from the work time table. A configuration is provided in which the presence or absence of inspection omission is determined by comparing the estimated work time corresponding to the current maintenance inspection plan. Thereby, the inspection omission which may occur when the inspection is executed according to the maintenance inspection plan determined for each facility can be detected with a simple configuration and with high accuracy.

  If it is determined that there is no inspection omission, the estimated operation time corresponding to the current maintenance inspection plan included in the operation time table is updated using the measured actual operation time. Thereby, when the same thing as this maintenance inspection plan is performed after the next time, the presence or absence of inspection omission can be determined more accurately.

  Furthermore, when it is determined that there is an inspection omission, a configuration for notifying that an inspection omission has occurred is provided. Thereby, it is possible to prevent an inspection omission when performing an inspection in accordance with a maintenance inspection plan determined for each facility. In addition, it is possible to prevent omission of inspection due to a registration error in the terminal device, and it is possible to contribute to the maintenance and improvement of the equipment quality higher than the conventional one.

  In the first embodiment, as a specific example of the equipment management system, the actual work time measurement unit 12 is configured to be included in the terminal device 10, and the storage unit 22, the inspection omission determination unit 23, and the work time table update unit are configured. Although the case where it comprised so that 24 and the alerting | reporting part 25 may be included in the elevator apparatus 20 was illustrated, it is not limited to this. That is, since the terminal device 10, the elevator device 20, and the external monitoring center can communicate with each other, the actual work time measurement unit 12, the storage unit 22, the inspection omission determination unit 23, the work, which are technical features of the present invention. If each of the time table update unit 24 and the notification unit 25 is included in any of the terminal device 10, the elevator device 20, and the external monitoring center, the same effect can be obtained.

  In the first embodiment, the case where the present invention is applied to an elevator has been described as an example. However, the present invention is not limited to this, and various maintenance inspections are periodically performed according to a determined maintenance inspection plan. The present invention can also be applied to such facilities (for example, passenger conveyor devices such as escalators and moving walkways).
