- FIG. 4 is a flowchart used for explaining the operation of the maintenance management system according to the present embodiment.
- the brake shoe will be described as an example of parts in the processing of the vehicle system 50.
- the brake shoe is an alloy made of cast iron.
- the brake shoe is a component that is pressed against the wheel tread by air pressure and flood control.
- the brake shoe is a component that generates a frictional force by sandwiching a brake disc mechanically coupled to the wheel to exert a braking force on the vehicle 5.
- Vehicle 5 is often equipped with a regenerative brake in addition to the brake mechanism using the brake shoes.
- the regenerative brake does not have sufficient performance when suddenly decelerating from a high speed. Therefore, the brake mechanism by the brake shoe is an indispensable component in the vehicle 5.
- the brake shoe is an important component that gives a sufficient braking force to the vehicle 5 under the condition that the regenerative brake does not function sufficiently.
- the brake shoes wear as they are used. Specifically, the greater the frictional force generated and the longer the frictional force is generated, the greater the amount of wear of the brake shoes. In other words, the greater the braking force and the longer the brake is applied, the greater the amount of wear on the brake shoes.
- the operating conditions of the vehicle 5 are various, and there are cases where the braking frequency is high due to operation on a slope line or a local train, and there are cases where the braking frequency is low due to limited express operation on a flat line.
- some vehicles 5 are equipped with a regenerative brake, while others are not. Therefore, the amount of wear of the brake shoes varies depending on the vehicle 5. Therefore, the detector 1 collects information on the amount of wear of the brake shoes for each vehicle 5 or each wheel (step S0).
- the amount of wear of the brake shoe may be output by directly detecting the thickness of the brake shoe.
- a method of outputting an estimated value of the amount of wear of the brake shoe based on the magnitude of the air pressure and the pressurizing time may be used. Further, a method other than these may be used.
- the data processing unit 2 generates life information based on the information from the detector 1 (step S2).
- the life information is information for estimating the deterioration status of parts.
- an example of life information is the ratio of the current thickness of the brake shoe to the thickness of the new brake shoe. Instead of this, the current thickness of the brake shoe itself may be used.
- Another example of life information is the product of the magnitude of air pressure and pressurization time. Instead of this, the ratio of the product of the magnitude of the air pressure and the pressurization time to the comparison value may be used.
- the data processing unit 2 calculates the remaining life of the brake shoe using the life information (step S3). In the following, for the sake of simplicity of explanation, it is assumed that the remaining life is included in the life information.
- the data processing unit 2 outputs the life information to the transmission processing unit 3 (step S4).
- the transmission processing unit 3 aggregates the life information of each component sent from the plurality of data processing units 2 in the vehicle or the formation (step S5), and transmits the life information to the maintenance management ground system 100 on the ground side (step S6). .. After that, the processes of steps S1 to S6 are repeated. In addition, the processes of step S7 and below are performed in parallel.
- the life information transmitted from the vehicle system 50 is input to and held in the data management unit 11 of the maintenance management ground system 100. Not only one organization but also the life information transmitted from the transmission processing unit 3 of the other organization is input to the data management unit 11.
- the data management unit 11 creates a database based on the life information of a plurality of organizations, and manages the created data (step S7).
- the database preferably includes the train number, vehicle number, reception time, device name, and part name in addition to the life information.
- the data management unit 11 calculates the average life of each part and holds it in the database (step S7). The calculation of the average life expectancy may be performed when the life information is received, or may be performed when the reception process is not performed.
- the data management unit 11 compares the received life information with the average life held in the database, and if the difference between them is equal to or greater than the determination value, generates the difference information (step S7).
- the difference information is, for example, information generated when the wear amount of the brake shoe of a certain vehicle is different from the average value, that is, when the difference between the wear amount and the average value of the same type of parts is large. Is. This difference information can be confirmed using the terminal devices 14, 15 and 16. When the difference information is generated, the generated difference information may be forcibly output to the terminal device 16 of the maintenance department. In this way, it is possible to quickly inform the maintenance personnel that the amount of wear of the brake shoes is excessive.
- the maintenance person can determine from the tendency of the difference information that the increase in the amount of wear of the brake shoes is due to an excessive air pressure or the like, which is due to an abnormality in the vehicle. As a result, the maintenance person can quickly take measures to reduce the amount of wear of the brake shoes.
- the life information received by the data management unit 11 is output to the subsequent determination unit 12 (step S7).
- the carry-in / out information is input to the determination unit 12 (see FIG. 2).
- the carry-in / out information includes train information, scheduled carry-in date information, scheduled carry-out date information, business return information, and the like.
- the train information is information on the train number and formation of the train on which the regular inspection is carried out.
- the scheduled delivery date information is information on the scheduled delivery date to the place where the periodic inspection is carried out.
- the scheduled delivery date information is information on the scheduled delivery date from the place where the periodic inspection is carried out.
- the business return information is information on the scheduled date when the train that has completed the regular inspection will return to commercial operation. Periodic inspections are planned and carried out in advance.
- FIG. 5 is a time chart used for explaining the operation of the maintenance management system according to the present embodiment.
- the horizontal axis represents time and the vertical axis represents the movement of maintenance work.
- periodic inspections are scheduled along the time axis.
- the "previous periodic inspection” is a periodic inspection that has already been carried out.
- “Next periodic inspection”, “one after another periodic inspection” and “one after another periodic inspection” are scheduled inspections in the future.
- the left end of the rectangle indicated by hatching represents the scheduled delivery date, and the right end of the rectangle represents the scheduled delivery date. Further, when the current time t is set to "t0", the determination unit 12 is always operating after the time t0.
- FIG. 5 shows part A, which is expected to reach the end of its life before the scheduled delivery date of the next periodic inspection.
- the determination unit 12 performs an order processing of the part A based on the predicted delivery date obtained by back-calculating the delivery date so that the replacement work of the part A can be carried out at the next periodic inspection.
- FIG. 5 shows part B, which is expected to reach the end of its life before the scheduled delivery date of the next periodic inspection. This determination is also carried out at time t0.
- the determination unit 12 determines a periodic inspection for carrying out the replacement work of the part B in consideration of the predicted delivery date.
- the replacement work can be performed in either the next periodic inspection or the next periodic inspection.
- the ordering process of the part B is performed so that the replacement work is carried out at the time of the next periodic inspection. By doing so, the order processing of the part B can be delayed, so that the current part B can be used for a longer time within the life range. As a result, the total amount of component B used can be reduced, and an increase in maintenance cost can be suppressed.
- the determination unit 12 determines whether or not there is a part that has reached the end of its life before the scheduled delivery date of the next periodic inspection (step S8). If there is no corresponding component (step S8, No), the process proceeds to step S13. When there is a corresponding part (step S8, Yes), the determination unit 12 extracts the part as a replacement-required part and gives an ordering instruction (step S9). Specifically, the determination unit 12 sends the ordering instruction information to the order processing unit 13. After the process of step S9, the processes of steps S10 to S12 and the processes of steps S13 and subsequent steps are performed in parallel.
- the delivery date information regarding the parts is also input to the order processing unit 13.
- the order processing unit 13 performs order processing of parts to the parts manufacturer based on the order instruction information and the delivery date information (step S10). For example, when the delivery date of a part is 30 days, the order processing is performed at least 30 days before the scheduled replacement date in the periodic inspection period for replacing the part in time for the replacement date of the part.
- the order processing unit 13 outputs the ordered part information to the terminal device 15 of the material department 62.
- the inventory information related to the ordered parts may be acquired from the inventory list managed by the inventory management unit 30, and the order processing may be performed based on the acquired inventory information. For example, if the in-stock item is not a part ordered for replacement at the time of periodic inspection but is acquired as a spare part, this may be utilized. In this way, the in-stock items can be effectively used.
- the material department 62 performs the receiving work (step S11).
- the received parts are stored in the parts warehouse 31. Further, when the parts are received, the arrival / departure information of the parts is input to the terminal device 15, and the number of arrivals / receipts, which is the number of the received parts, is reflected in the inventory list (step S12).
- step S9 the determination unit 12 determines whether the periodic inspection is currently being carried out (step S13). If the periodic inspection is not being carried out (steps S13, No), the process returns to step S7 and the processing from step S7 is repeated. On the other hand, if the periodic inspection is being carried out (steps S13, Yes), it is determined whether or not there is a part that has reached the end of its life before the scheduled delivery date of the next periodic inspection (step S14). If there is no corresponding component (step S14, No), the process returns to step S7 and the process from step S7 is repeated.
- step S14 when there is a corresponding part (step S14, Yes), the determination unit 12 instructs the part replacement instruction unit 20 to replace the part in order to replace the part (step S15). Specifically, the determination unit 12 outputs the component replacement instruction information to the component replacement instruction unit 20. After the process of step S15, the process of repeating the process of step S7 and subsequent steps and the process of step S16 are executed in parallel.
- the parts replacement instruction unit 20 outputs the replacement instruction information generated based on the parts replacement instruction information to the terminal device 16 of the maintenance department 63.
- the replacement instruction information is information necessary for the replacement work of the parts, and includes at least information on the replacement part name, the device name, the vehicle number, the replacement date, and the number of parts.
- instructions and information for parts replacement can be obtained through the terminal device 16.
- the parts replacement work is performed (step S16).
- the work completion report is made using the terminal device 16, and the number of used parts is reflected in the inventory list.
- the determination unit 12 determines whether or not the first part, which is expected to reach the end of its life after the scheduled delivery date of a certain periodic inspection, needs to be replaced with a new replacement part within the period of the periodic inspection. doing. Assuming that the "certain periodic inspection” referred to here is the “next periodic inspection” in FIG. 5, it is predicted that the "part A” in FIG. 5 will reach the end of its life after the scheduled delivery date of the "next periodic inspection”. It is a part. Therefore, the "first component” referred to here corresponds to "part A”. Further, assuming that the "certain periodic inspection” referred to here is the “sequential periodic inspection” in FIG. 5, it is predicted that the "part B” in FIG. 5 will reach the end of its life after the scheduled delivery date of the “sequential periodic inspection”. It is a part to be used. Therefore, the "first component” referred to here corresponds to "part B”.
- the judgment unit is predicted to reach the life after the scheduled carry-out date to the place where the periodic inspection is carried out. It is determined whether the part needs to be replaced with a new replacement part within the period of the periodic inspection. As a result, the first component can be used for a longer period of time within the life of the first component, so that the total amount of the first component used can be reduced. As a result, smooth maintenance services can be provided while suppressing an increase in maintenance costs.
- the order processing unit further orders the replacement parts based on the delivery date prediction information that predicts the delivery date of the replacement parts.
- the order processing unit can replace the first part with a replacement part when the periodic inspection is performed before the life prediction time, which is the time when the first part is predicted to reach the end of its life.
- the ordering process for replacement parts is performed as described above. By these processes, the quantity of inventories can be reduced and the storage period in the parts warehouse can be shortened. As a result, smooth maintenance service can be reliably performed.
- the inventory management department when the replacement parts arrive at the place where the periodic inspection is carried out, the inventory management department receives the arrival information indicating that the replacement parts have arrived and the number of the parts of the replacement parts that have arrived. This is reflected in the inventory information of the first part. Further, when the replacement work of the first part for the replacement part is completed, the inventory management unit receives the completion information to the effect that the part replacement is completed and the usage information of the first part and reflects them in the inventory information. Further, when the judgment unit determines that it is necessary to replace the first part with a replacement part within the periodic inspection period, the parts replacement instruction unit provides instruction information for replacing the first part with a replacement part. Generate and output. By these processes, smooth maintenance service can be surely carried out.
- the data management unit calculates the average life of a plurality of parts of the same type using the life information, and when the life of the first part is different from the average life, Generates and outputs difference information indicating that there is such a difference. As a result, it is possible to determine an abnormality in a part in a normal work that is separate from the inspection work, and it is possible to suppress an unexpected defect.
- FIGS. 1 and 2 up to the data processing unit 2 is mounted on the vehicle 5, and the data management unit 11 and subsequent units are arranged on the maintenance management ground system 100, but the configuration is not limited to this. These components may be arranged at any location on the vehicle or on the ground as long as information can be exchanged.
