In the maintenance work management apparatus of this embodiment, maintenance work belonging to a sales office in charge of an area installed in a building, for example, an elevator, is performed by a maintenance department 3 for a maintenance work of an equipment. Is performed periodically, and when a part is replaced due to a failure or preventive maintenance, the part is handled in the following procedure. In other words, the maintenance worker can enter the above part name, part model number, replacement date, replacement reason,
Parts replacement information such as failure content is input to the portable terminal device 7a, and is collected from the building where the elevator is installed to a sales office. For each of the collected parts, recyclable products and non-recyclable products are separately packed. It is sent to the recycling factory 4.

Next, in the recycling factory 4, if the sent collected parts, for example, the printed board B for controlling the elevator as shown in FIG. 2A is a collected part for which no part management number is set, the terminal It is registered in the apparatus 4a and numbered as a reception number of the reproduced part, and the number is issued as a part management number together with information on the part name and the part type as a barcode label A by the barcode printer 4c and printed. Affixed to the plate B, the collection reception date of each collection component, collection information of the branch office / sales office, etc. of the collection source are stored in the component history management information storage unit 6e of the database 6 via the terminal device 4a and the network 5. On the other hand, in the case of a component for which a component management number has already been set, the barcode label A is read using the barcode reader 4b and input to the terminal device 4a. Next, the terminal device 4a searches the component history management information storage unit 6e via the network 5 based on the read information, and newly registers it as a collected component. At this time, if the limit frame of the number of times of reproduction is determined for the collected part, and the input collected part exceeds the maximum number of times of reproduction, the terminal device 3a
Is displayed on the reception screen. If the number of times of reproduction has not exceeded, the parts management section 1
When the performance information at the time of replacement is registered in the database 6 of the work performance management information storage unit 6c, the replacement reason code, the replacement date, the collection source branch / office code, the failure code, etc. The information is read out and stored in the part history management information storage unit 6e as collection information.

The diagnosis section collects the collected parts via the terminal device 4a and the network 5. Maintenance department 3 by part number
Diagnosis and diagnostic tests of the reusability and rehabilitation method are performed while referring to the parts replacement information input in step 4.
Information such as a diagnosis result and a content of a diagnostic test is input to the terminal device 4a for each collected part number. Next, the recycling department, which recycles recovered parts, recycles recovered parts based on the results of diagnosis, such as the repaired part of the recovered parts and the repair method. Is input to the terminal device 4a.

The parts (for example, the printed board B) reproduced in this manner are represented by bar codes (not shown) that code the part management numbers and the part models registered in the part history management information storage unit 6e of the database 6. After being issued by the code printer 4c and affixed to a packing box (not shown), it is sent to the central parts warehouse 2. Further, the recycled parts (for example, the printed board B) recycled in the recycling factory 4 are temporarily stocked in the central parts warehouse 2 as the base warehouse before being sent to the branch office or the sales office as the maintenance department 3. In the central parts warehouse 2, as a warehousing operation, a packing box (not shown) for packing the recycled parts and a bar code label A attached to a printed board B as a recycled part are read by a bar code reader 2b, and the recycled part is sent to the terminal device 2a. The user inputs a number, a department code, and the like, updates the database 6 via the network 5, and performs the same operation when leaving the warehouse. Also, in the warehouse provided at the branch office / sales office, which is the maintenance department 3, the bar code is read and updated every time the warehouse is moved in and out, similarly to the central parts warehouse 2.

Next, the processing performed by the portable terminal device 7a at the time of component replacement will be described with reference to the flowchart of FIG. That is, first, in step S1, when a part replacement occurs in the maintenance work, the result is input to the portable terminal device 7a and stored in the database 8. At this time, the result registration screen of the portable terminal device 7a is started, and the barcode label D of the delivery slip C shown in FIG.
And temporarily stores it in the memory of the portable terminal device 7a. Here, the bar code label D includes, for example, a slip number, a customer name, a part number, a part number, a part number, a part number, a part number, a part number, a part number, a part number, a part number, a part number, a part number, a part number, etc. Printed.

Next, in step S2, the part removed for replacement, for example, the bar code label A on the printed board B is read and stored in the same manner as described above, and in step S3, a new part prepared for replacement is Read a bar code (not shown). Next, in step S4, the portable terminal device 7a
Compares the part type information of the delivery slip C read in step S1 with the part type information of the old part read in step S2, and determines whether or not the part types are the same.
If the part types are the same, the flow proceeds to the next customer collation processing determination (step S7), while if the part types are different, the flow proceeds to the part type compatibility determination processing (step S5). In this step S5, the portable terminal device 7a refers to the type information of the input component from the component type information storage unit 8b of the database 8, and
It is determined whether or not there is compatibility between the old and new parts. If there is compatibility between the old and new parts, the process proceeds to the next customer verification processing determination (step S7). If there is no compatibility between the old and new parts, After the caution message is displayed on the display screen of the portable terminal device 7a, the process proceeds to a determination input waiting process (step S6) as to whether to continue the registration process. Next, when the input result indicates that the registration has been canceled in step S6, the registration is canceled (step S8).
Then, in step S8, the part result registration process is stopped. On the other hand, when the registration process is continued in step S6, the process proceeds to the next customer collation process determination (step S7).

Next, in step S7, the portable terminal device 7a refers to the type information of the input component from the component type information storage section 8b of the database 8 to determine whether the component needs to be verified by the customer, If it is not necessary, the process proceeds to a registration process (procedure S13). On the other hand, if customer verification is required, the process proceeds to a customer management number input waiting process (procedure S9). In addition,
This customer management number input waiting process is a process for preventing misuse of parts. It is not necessary for low-priced consumable parts, etc. Is a process for confirming that the process has been correctly used for the target customer equipment. Whether this process is necessary is set in advance for each component model and is stored as component model information.

Next, in step S9, an input message of the customer management number is displayed on the display screen of the portable terminal device 7a, and input wait processing is performed. At this time, the customer management number is input, in principle, by reading a barcode (not shown) provided in advance in the customer equipment using the barcode reader 7b. Alternatively, the customer management number may be directly input by a key or a predetermined code may be input.

Next, when the customer management number is input in the above step S9, the next customer management number collation processing (step S10).
If the customer management number registered in the delivery slip C read in step S1 matches the number entered in step S9 as a match in step S10, the process proceeds to the next registration process (step S13). On the other hand, if the customer management number does not match the input number, the correction registration process (step S
Proceed to 11). In this step S11, a message is displayed as to whether or not to make a correction registration, a key input is waited, and if the input result does not require correction, the process proceeds to the registration process (step S13). Proceed to S12). In this step S12, the corrected items such as the customer's name are directly changed and registered. In step S13, information such as the outgoing slip C, the replaced old parts, and the new parts for replacement are stored in the replacement work result information. Database 8 as
Is stored in the work result information storage unit 8c.

After the work record information is stored in the portable terminal device 7a in this way, the work record information is temporarily input to the terminal device 3a by connecting the portable terminal device 7a to the terminal device 3a of the maintenance department 3, Further, since the information is transmitted to the parts management section 1 via the network 5, the related items in the database 6 are updated based on the work result information. At this time, examples of information updated in the database 6 include a part type in the customer product specification chart information storage unit 6b, a replacement date and a work execution date in the work result management information storage unit 6c, a delivery number, and a replacement of part history management information. For example, the date and the customer management number of the use destination.

In the maintenance work management apparatus of this embodiment configured as described above, the component information and the delivery information identified by the bar code labels A and D are stored in the bar code readers 2b to 4b and 7b.

Can be prevented from being misused.

Further, in the maintenance work management apparatus of the present embodiment, when the information identified by the bar code labels A and D with respect to the collected parts is fetched by the bar code readers 2b to 4b and 7b, the terminal device 4a of the regeneration factory 4 Collects data based on the results of parts replacement, creates a list of parts that have already been replaced, and uses this data to collate collected parts with returned parts and manage the number of parts. It is possible to estimate the amount of work required to regenerate parts. For example, information on the exchange of the printed board B at the recycling factory 4 is obtained daily from the work result management information storage unit 6c of the database 6, and the obtained printed board exchange work data and the information for regenerating the printed board B are sent. By checking the bar code label A of the printed board B with the reception data read by the bar code reader 4b, it can be confirmed that the printed board B is not sent from the maintenance department 3, and the printed board B not sent is sent. The request can be accurately sent to the corresponding maintenance department 3 and the waste that the maintenance department 3 discards the printed board B that can be reused can be reliably prevented. In addition, since the number of exchanged printed boards B can be ascertained before being sent, it is possible to plan the work time and personnel required for the printed board B regeneration. Furthermore,
The replacement reason and the like registered when the maintenance department 3 replaces the printed board B can be used as a diagnostic material for specifying a defective portion in the part regenerating process, and efficient and accurate regenerating work can be performed.

Further, in the maintenance work management apparatus of the present embodiment, the reproduction part number,
