Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure sign of a transport device which gives a worker who carries out maintenance work of a transport device for transporting passengers such as elevators around a building to schedule information of work including inspection work of required places. It belongs to the technical field of inspection work support equipment.

[0002]

2. Description of the Related Art At present, many buildings are equipped with various types of building equipment such as a passenger transport device such as an elevator and an alarm device for detecting an abnormal situation such as a fire and issuing an alarm. Since these building facilities are closely related to the daily activities of the occupants, the failure of these building facilities causes a great deal of inconvenience to the occupants of the building and those who come and go. Therefore, it is necessary to always carry out proper maintenance and inspection (maintenance) of such building equipment. However, since accurate maintenance and inspection of such building equipment requires specialized knowledge, it is usually necessary to carry out the maintenance of building equipment. Maintenance work is often outsourced to specialized maintenance companies. The outsourced maintenance company regularly dispatches specialized workers to meet the needs of customers to perform inspection, repair, and maintenance of building equipment.

By the way, when performing maintenance work on building equipment, especially elevators, the work plan of the customer building equipment and the contents of the work at the site are created by the central information processing device of the maintenance company, and the work is now performed at each sales office. It is often given as instruction information. That is, this central information processing device provides work instruction information such as work type, work time, and repair plan for each month to each subordinate office, and each office uses the terminal information processing device installed there to perform work. A traveling work plan for each worker is created based on the instruction information. Each worker patrols each customer building according to the patrol work plan thus created,
Perform elevator maintenance work based on the instructed work plan.

[0004] Each worker carries a portable computer,
The maintenance work of each customer building is executed according to the work plan stored in the portable computer. The portable computer stores work instruction information transmitted from the central information processing device and transmitted through the terminal information processing device, and each worker displays the work instruction information on the display of the portable computer. Is displayed, the maintenance work of the day is executed according to the displayed information, and execution information (work type, work time, etc.) of the executed work is stored in the storage unit of the portable computer. When the scheduled work on that day is completed, the worker causes the terminal information processing device to transmit the work execution information stored in the storage unit of the portable computer. In the sales office, the terminal information processing device checks the contents of the work execution information received from the portable computer of the worker, and then transmits the information to the central information processing device. The central information processing device that has received the work execution information grasps and analyzes the progress of the scheduled work on that day based on the information, and reflects the result in the creation of the next work plan.

[0005] Incidentally, the maintenance work of the elevator includes the work of maintaining the operation of the elevator condition monitoring device connected to the elevator control device. The elevator status monitoring device checks whether the management values of the components included in the various devices, for example, the management values defining the range between the contacts and the adjustment range of the operating pressure are kept within a preset registration range. Some of the measurement and management of various control values for inspection work are performed on behalf of workers. More specifically, the number of times of the relay operation of the elevator control device, the number of times of opening and closing the door of the elevator, and the like are constantly measured to monitor whether the value is within the above set range. When it is detected that is not a normal value, the predictor detects the sign and issues the sign information before the elevator fails.

That is, the count values and measured values detected by the elevator control device and various detectors, such as the response time of the relay, the opening and closing operation time of the door, the amount of extension of the rope that suspends the car, and the like are registered in advance. When a sign of abnormality is shown beyond the range, a failure sign code predetermined according to the contents of the sign is read out, and is periodically transmitted to the central information processing apparatus as failure sign information together with the measurement data. The central information processing device creates failure sign work instruction information for each item based on the received failure sign information. The failure sign work instruction information is classified into two classes, A and B, according to the degree of urgency, and is periodically transmitted to a terminal information processing device of a business office that manages the elevator. It is to be noted that the class A sign has a high possibility of failure or malfunction in the near future if left unchecked, and the class B sign has a low possibility of failure in the near future, but a failure will occur in the medium term. There is a fear.

The terminal information processing apparatus creates work instruction information in which a change is made to the traveling work plan in accordance with the contents of the received failure sign work instruction information. That is, for the class A failure sign inspection work, a work execution instruction is issued in conjunction with the next scheduled patrol maintenance work, and for the class B failure sign inspection work, the manager of the sales office issues the failure sign work instruction information. In consideration of the contents of the above, a failure sign inspection work is appropriately instructed within a predetermined period.

The sign work instruction information is transferred to the portable terminal device of the worker together with the work instruction information for instructing the scheduled patrol maintenance work. The operator performs a failure sign inspection work in accordance with the failure sign work instruction information displayed on the display unit of the portable terminal device, and stores the contents of the performed work in the portable terminal device as execution information. The execution information of the failure sign inspection work stored in the mobile terminal device is later transferred to the terminal information processing device,
The information is transmitted to the central information processing device via the device. The central information processing device stores the received execution information of the failure sign inspection work as log information.

[0009]

In the above-described prior art, a failure sign work instruction issued to a worker is added to a maintenance work assigned according to a traveling work plan. It may interfere with the performance of the maintenance work and invite overwork. If the deviation from the setting range of the measured value is not so large, there is no worry about the left, so the failure sign inspection work included in the failure sign work instruction information has deteriorated to some extent, and the class that the sign of failure is clear Although there is a high possibility that the sign inspection work of A is performed, the normal maintenance work is given priority for the sign inspection work of class B, and as a result, it is often delayed and the execution is delayed.

[0010] Therefore, there is a problem that an instruction for a repair measure is issued only after the occurrence of the failure without any countermeasure being taken despite the sign of the failure. In addition, although the measured value detected by the detector is not outside the set range, there is a high possibility that the measured value will be out of the set range in the near future.However, conventionally, as a failure sign until the measured value actually falls outside the set range, It was not detected. The present invention solves such problems in the prior art, and does not hinder the execution of maintenance work, which is a routine work of workers, and further ensures the failure sign inspection work even if there is a minor sign of failure. It is an object of the present invention to provide a failure sign inspection work support device for a transport device that can perform the above.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention solves the above-mentioned problem by performing the above-mentioned inspection work in a case where the inspection work is related to a scheduled maintenance work. The schedule information of the work to be performed in conjunction with the work is given. Preferably, the schedule information of the work is given to the worker by displaying the schedule information on the display of the portable computer carried by the worker. When the measurement data obtained by measuring the operation state of the required portion of the transfer device is approaching or tends to approach the boundary of the pre-registered set range, it is determined that there is a sign of a failure of the portion of the transfer device. It is something to do.

[0012]

The elevator monitoring apparatus 2 has a tendency that the value of a detection signal obtained by detecting the operating state of the elevator 1 by various detectors is likely to reach an abnormal value that is not within a preset range or an abnormal value in the near future. If so, a sign detection code corresponding to the value is issued. The storage unit 4c of the terminal information processing device 4 installed in the sales office stores work contents, customer information, individual elevator information, maintenance work related to maintenance work of the elevator 1 installed in each customer building 10 controlled by the business office. Information such as a work plan, work history information, and measurement data detected by various detectors is stored.

Next, the operation of this embodiment will be described. First, normal patrol maintenance work will be described. The central information processing device 3 creates maintenance work instruction information for each elevator 1 installed in each customer building 10 based on the maintenance work execution information of each worker read from the storage unit 3c. The maintenance work instruction information includes information such as details of inspection and maintenance work of each building facility, a repair plan, and scheduled maintenance work time. The maintenance work instruction information is created at a fixed time every month, and is transmitted from the central information processing device 3 to the terminal information processing devices 4 installed in each of the subordinate business offices. This maintenance work instruction information is stored in the storage unit 4c as maintenance work instruction information for the next month.

The terminal information processing device 4 is a central information processing device 3.
A maintenance work plan for the next month is created based on the maintenance work instruction information received from the customer and the customer information and maintenance work execution information stored in the storage unit 4c in advance, and this information is stored in the storage unit 4c. It should be noted that the tour maintenance work plan is created for each group and each worker at each business office. Then, information necessary for the worker to perform the patrol maintenance work that is carried out every day is prepared for each worker. The on-site maintenance work planning procedure is performed as follows. First, a work plan for one day on the work day of each worker stored in the storage unit 4c, that is, tour maintenance work plan information such as a customer building 10 scheduled to be visited on the day, work contents, and scheduled work time. At the same time, it reads out the maintenance work information necessary for performing the maintenance work such as customer information, elevator individual information, work history information, measurement data, etc. for each elevator, and carries these tour maintenance work plan information and maintenance work information. It is converted into a format that can be received by the type computer 5.

On the day of the work, the portable computer 5 is connected to the terminal information processing device 4 and receives the traveling maintenance work plan information and the maintenance work information. The transferred information is stored in the storage unit 5
c. The worker goes to the work site with the portable computer 5 receiving the predetermined information. Upon arriving at the work site, the display section 5d of the portable computer 5 displays the tour maintenance work plan information and the maintenance work information, and performs the tour maintenance work according to the information.

The central information processing device 3 creates failure sign inspection work instruction information from the sign detection code received from each elevator monitoring device 2 several times a month from the elevator monitoring device 2 and the accompanying measurement data, etc. Transmit to the device 4. In the terminal information processing device 4, the failure sign detection code is A, B,
C is classified into three classes, and the failure sign of the class A is assigned as a failure sign inspection work to be performed together with the next round maintenance work as in the past, and the failure sign of the class B is For example, a failure sign inspection work is instructed by a manager of a sales office within a predetermined period. Therefore, in this specific example, the terminal information processing device 4 allocates the failure sign inspection work to the measurement data determined to be the class C failure sign. Note that the failure sign of class C is determined to be measurement data at the very end of a predetermined set range or measurement data that will be out of the set range in the near future.

Next, the operation of the failure sign inspection work assignment processing performed by the terminal information processing device 4 of the business office will be described. FIG. 2 is a table showing a failure sign inspection work correspondence table stored in the storage unit 4c of the terminal information processing apparatus 4. As shown in the figure, the failure sign inspection work correspondence table includes, from the left, a sign inspection work number C1, a sign inspection work instruction item C2, a device model code C3, a related maintenance work code C4, and a failure sign inspection work instruction. It is composed of a column C5. The sign inspection work instruction item C2 indicates the content of the sign failure inspection work performed by the operator, and the sign inspection work number C1 is a number for specifying the item.

The device model code C3 is a code for specifying a component of a different type of elevator, and the related maintenance work code C4 is a code of a maintenance work related to the item. When there is a predictive inspection work instruction item corresponding to the failure predictive inspection work instruction code C5 in the failure sign inspection work instruction code C5 column, a cross mark with the item is marked with a triangle, and at the same time, it corresponds to the work instruction item. When there is a device type, a cross mark at the intersection with the item is indicated.

Upon receiving the failure sign inspection work instruction information from the central information processing device 3, the terminal information processing device 4
2 is read out from FIG. 2C, and the intersection of the failure sign inspection work instruction code C5 and each sign inspection work instruction item in the failure sign inspection work instruction code C5 column is marked with a triangle. It is determined whether or not there is a warning sign inspection work instruction code C5, and a sign inspection work instruction item C2 and a sign inspection work number C1 thereof are extracted.
Then, the related maintenance work location code C4 related to the sign check work instruction item is extracted and stored in the storage unit 4c together with the sign check work number C1.

Next, the terminal information processing device 4 performs a normal maintenance work assignment process, and then reads out the related maintenance work location code C4 associated with the predictive inspection work number C1 from the storage unit 4c, and performs a round trip planning. It is determined whether there is a work location code that is identical to the work location code that specifies the work location of the elevator to be subjected to the maintenance work assigned to the table. If there is a sign having the same sign, the predictive inspection work number C1 is extracted, assigned to the traveling work plan table as a failure predictive check operation related to the maintenance work, and stored in the storage unit 4c.

As described above, only the predictive inspection work instruction item C2 in which the same work place as the work place of the elevator to be subjected to the maintenance work assigned to the patrol work schedule table is the related maintenance work place is regarded as the maintenance work. It is assigned to the patrol work schedule as a sign inspection work to be performed at the same time. For example, if the maintenance work of the brake device is assigned to the patrol work schedule table and the failure sign inspection work instruction code C5 indicating the sign inspection work instruction item C2 in which the brake device is a related maintenance work site is given. For example, the predictive inspection work instruction item C2 is assigned to the patrol work schedule so as to be performed together with the maintenance work. Thus, the failure sign inspection work can be performed without hindering the maintenance work, which is the regular work of the worker.

The data of the patrol work schedule table to which the failure sign inspection work is assigned in this manner is stored in the portable computer 5 before the worker goes to the work site to carry out the patrol work.
Is read from the storage unit 4c of the connected terminal information processing device 4, transferred to the portable computer 5, and stored in the storage unit 5c. The storage unit 5c stores a sign check item correspondence table in which the sign check operation number C1 and the sign check operation instruction item C2 are associated with each other. As the sign check operation instruction information, data of the sign check operation number C1 is used. Only is remembered.

The worker arriving at the work site operates the input unit 5e of the portable computer 5 to read the data of the tour schedule table from the storage unit 5c, and displays the tour schedule table on the display unit 5d. Display. When performing maintenance / inspection of the work location corresponding to the related maintenance work location code C4 in the course of performing the maintenance work, the failure predictive inspection designated by the predictive inspection work instruction item C2 corresponding to the predictive inspection work number C1. Perform the work together. When the scheduled maintenance work and the failure sign inspection work are completed, the operator operates the input unit 5e of the portable computer 5 to input information on the result of the maintenance work and the failure sign inspection work.

The work execution information is stored in the storage unit 5c. The worker who has returned to the office connects the portable computer 5 to the terminal information processing device 4 and causes the work execution information stored in the storage unit 5c to be transferred to the terminal information processing device 4. These pieces of work execution information are stored in the storage unit 4c of the terminal information processing device 4 as work history information, and the unexecuted work is required instruction work information during the next and subsequent round maintenance work.

As described above, in this specific example, even if the measurement data measured by the detector or the like does not fall outside the predetermined setting range, the value is very close to the boundary or likely to cross the boundary in the near future. In this case, it is determined that there is a sign of failure, and only the work that is related to the work location of the maintenance work, which is a regular operation, is assigned to the failure sign inspection work. Can be reduced,
Before a failure occurs in the elevator, a sign of failure can be reliably taken.

[0028]

As described above, according to the first aspect of the present invention, when the inspection work target location is related to a scheduled maintenance work target location, the inspection work is performed by the maintenance work. Since the schedule information of the work to be performed together with the work is given, the failure sign inspection work can be reliably performed without hindering the execution of the maintenance work which is the regular work of the worker. According to the second aspect of the present invention, the schedule information of the work is displayed on the display of the portable computer carried by the worker. Work schedule information can be reliably and simply given to the worker who performs the work. According to the third aspect of the present invention, when the measurement data obtained by measuring the operation state of a required portion of the transfer device is approaching or tends to approach the boundary of the pre-registered set range, Since it was determined that there was a sign of failure at the location,
Even if there is a slight failure sign, the failure sign inspection work can be reliably performed.
