Note that in each drawing, the same or corresponding components are designated by the same reference numerals, and description thereof will be omitted as appropriate.

[0011] As shown in Fig. 1, a maintenance support system 100 according to this embodiment includes a maintenance support device 200. In this embodiment, the maintenance support system 100 is configured as a system that presents candidates for parts to be reused when parts removed from a plurality of devices (lane devices LE, described later) used in a toll collection system 1 on a toll road as shown in Fig. 2 are reused in the device or other devices.

[0012] First, with reference to Figure 2, a toll collection system 1 to be maintained in the maintenance support system 100 of this embodiment will be described. As shown in Figure 2, the toll collection system 1 according to this embodiment is installed, for example, at a toll gate (entrance toll gate or exit toll gate) of a toll road, and collects tolls from both ETC vehicles and non-ETC vehicles traveling on a lane L connecting the toll road and an ordinary road. Here, ETC (registered trademark) (Electronic Toll Collection System) is an electronic toll collection system. An ETC vehicle is a vehicle equipped with an on-board unit for ETC, and a non-ETC vehicle is a vehicle not equipped with an on-board unit. Note that Figure 2 illustrates a vehicle A equipped with an on-board unit α.

[0013] In this embodiment, an example will be described in which the toll collection system 1 is installed at an exit toll gate. Hereinafter, the direction in which the lane L extends (±X direction) will be referred to as the "lane direction." The toll road side of the lane direction (-X side) will also be referred to as the "upstream side," and the general road side (+X side) will also be referred to as the "downstream side." Furthermore, the width direction of the lane L (±Y direction) will be referred to as the "lane width direction."

[0014] 2 shows an example in which only one lane L is provided at the toll gate, but this is not limiting. In other embodiments, multiple lanes L may be provided at the toll gate.

[0015] As shown in Figure 2, the toll collection system 1 includes an ETC facility 2, a lane control device (or lane monitoring equipment) 10, and a remote monitoring device 11. The toll collection system 1 also includes vehicle detectors S1-1, S1-2, S2, S4-1, and S4-2, a vehicle type discrimination device 4, a departure controller 25, a crossing gate 26, a lane monitoring control panel 27, a roadside indicator 28, an entrance light 51, a lane sign board 52, a loudspeaker 53, a lane monitoring camera 6, and a toll gate data server 12. The remote monitoring device 11 is installed in a maintenance office 71 located away from the toll collection system 1. The toll gate data server 12 is installed in a toll gate office 72.

[0016] The ETC equipment 2 is a group of devices that executes a toll collection process to automatically collect tolls from ETC vehicle A equipped with an on-board unit α via wireless communication. Specifically, the ETC equipment 2 includes, for example, a roadside wireless device (also referred to as a roadside antenna) 21, an intercom slave 22, etc., and executes toll collection process under the control of a lane control device 10 in cooperation with vehicle detectors S1-1, S1-2, S2, S4-1, and S4-2, a vehicle type discrimination device 4, etc. The ETC equipment 2 can also be considered as a configuration including the lane control device 10, vehicle detectors S1-1, S1-2, S2, S4-1, and S4-2, and a vehicle type discrimination device 4, etc. The intercom slave 22 is installed on island I near and upstream of the start control device 25, and performs voice communication, for example, between vehicle A that has failed to collect tolls properly and the toll gate office 72. For example, a call is initiated when the driver of vehicle A or the like presses the call button on the intercom handset 22 and an operator such as a toll collector at the toll gate office 72 answers the call.

[0017] Vehicle detectors S1-1 and S1-2 are installed on islands I provided on both sides of lane L at vehicle detection positions next to the crossing barrier 26 in the lane direction on the most upstream side (-X side), and detect vehicles entering lane L. Vehicle detectors S1-1 and S1-2 are, for example, transmission-type vehicle detectors as shown in FIG. 2, and have a pair of a light emitter and a light receiver installed opposite each other across lane L. Vehicle detectors S1-1 and S1-2 output detection signals that can distinguish the presence or absence of a vehicle at the entry detection position based on whether the light emitter receives the light and the receiver receives it. Vehicle detectors S1-1 and S1-2 output detection signals indicating that no vehicle is present at the entry detection position while the receiver receives light. On the other hand, vehicle detectors S1-1 and S1-2 output detection signals indicating that a vehicle is present at the entry detection position while the receiver does not receive light. The vehicle detectors S1-1 and S1-2 are arranged in a double row to detect forward and backward movement of the vehicle.

[0018] The roadside device 21 is installed above the road surface downstream (+X side) of the vehicle detectors S1-1 and S1-2 in the lane direction. When the vehicle detectors S1-1 and S1-2 detect that a vehicle has entered the lane L, the roadside device 21 emits radio waves for wireless communication toward a predetermined communication area R1 on the lane L. For example, as shown in FIG. 1, the communication area R1 is set to the range from the vehicle detectors S1-1 and S1-2 to the vehicle detector S2. The roadside device 21 transmits and receives various commands and information for executing toll collection processing to and from the on-board device α of the ETC vehicle A present within the communication area R1 via wireless communication.

[0019] The vehicle type discrimination device 4 includes a front photographing unit 41, an image processing unit 42, and an axle detector 43. The front photographing unit 41 is an imaging device that photographs in the -X direction and photographs a front image of vehicle A. The image processing unit 42 recognizes the license plate information of vehicle A based on the front image of vehicle A photographed by the front photographing unit 41. The axle detector 43 has a tread as a replaceable part and detects the number of axles of vehicle A. The vehicle type discrimination device 4 discriminates the vehicle type of vehicle A based on the information recognized by the image processing unit 42 and the information detected by the axle detector 43, and transmits the photographed image and information indicating the discriminated vehicle type to the lane control device 10.

[0020] The vehicle detector S2 is installed on the island I at a communication end position downstream (+X side) of the roadside device 21 in the lane direction, and detects the passage of a vehicle. The vehicle detector S2 has the same device configuration as the vehicle detectors S1-1 and S1-2. When the vehicle detector S2 detects that a vehicle has passed, the roadside device 21 stops emitting radio waves.

[0021] The lane control device 10 executes a toll collection process to collect a toll from ETC vehicle A. For example, the lane control device 10 acquires information including the model of ETC vehicle A, the position (entrance toll gate) and date and time when ETC vehicle A entered the toll road, and the method of payment for the toll (credit card number, etc.) from the on-board device α via the roadside wireless device 21, and performs processes such as calculation and settlement of the toll according to the model and mileage of ETC vehicle A based on this information. The lane control device 10 may be installed on island I as shown in FIG. 1 or in the toll gate office 72.

[0022] In addition, in this embodiment, the lane control device 10 acquires sensor information, image information, discrimination information, identification information, and call data acquired or generated by vehicle detectors S1-1, S1-2, S2, S4-1, and S4-2, vehicle type discrimination device 4, lane monitoring camera 6, etc., and transmits them to the remote monitoring device 11 and the toll booth data server 12.

[0023] The departure controller 25 is installed on the island I downstream (+X side) of the intercom handset 22 in the lane direction. The departure controller 25 opens (allows vehicles to pass) or closes (restricts vehicle passage) the lane L by raising and lowering an opening / closing bar (hereinafter referred to as a barrier bar) in accordance with opening / closing commands from the lane control device 10 or the like. When the toll collection process is completed, the lane control device 10 outputs an opening command to the departure controller 25 to allow vehicles to pass. Furthermore, when the lane control device 10 detects a vehicle's exit from the lane L using vehicle detectors S4-1 and S4-2 (described below), it outputs a closing command to the departure controller 25 to restrict the passage of following vehicles. When the barrier bar is closed and vehicle A is about to collide with (or has collided with) the barrier bar, the departure controller 25 has the function of preventing the barrier bar from being destroyed by tilting it in the traveling direction of vehicle A. The launch controller 25 includes replaceable parts such as a blocking rod, an opening / closing motor for opening and closing the blocking rod, and a blocking rod breakage recovery motor for returning a broken (fallen) blocking rod to its normal state.

[0024] Vehicle detectors S4-1 and S4-2 are installed on island I at the exit detection position on the most downstream side (+X side) in the lane direction, and detect the passage of vehicles (exiting from lane L). Vehicle detectors S4-1 and S4-2 have the same equipment configuration as vehicle detectors S1-1 and S1-2.

[0025] 1 shows an example in which the vehicle detectors S1-1, S1-2, S2, S4-1, and S4-2 are transmission-type vehicle detectors, but the present invention is not limited to this. In other embodiments, the vehicle detectors may be reflection-type vehicle detectors.

[0026] The crossing barrier 26 opens (allows vehicles to pass) or blocks (restricts vehicle passage) the lane L by raising or lowering the barrier bar in accordance with opening / closing commands from the lane control device 10. The crossing barrier 26 includes replaceable parts such as a barrier bar, an opening / closing motor, and an LED (light-emitting diode) display unit. The entrance light 51 switches the display of the entrance light in accordance with control commands from the lane control device 10 to allow or restrict passage through the lane L. The lane display board 52 displays the lane L's operating status (e.g., closed, ETC-only, etc.) under the control of the lane control device 10. The lane display board 52 includes replaceable parts such as an LED display unit. The loudspeaker 53 outputs, for example, a predetermined sound under the control of the lane control device 10. The lane monitoring camera 6 captures images of the lane L and transmits the captured image (video) information to the lane control device 10. The roadside indicator 28 is a display board that displays the toll to be collected, vehicle classification, etc. to the vehicle A. The toll booth data server 12 is configured using a computer such as a personal computer equipped with an input unit and a display unit, and receives monitoring data, history information, information representing the forward image of vehicle A, etc. from the lane control device 10, displays it on the display unit, and transmits predetermined information such as the history information and information representing the forward image of vehicle A to the remote monitoring device 11, etc.

[0027] In this embodiment, the vehicle detectors S1-1, S1-2, S2, S4-1 and S4-2, the axle detector 43, the start control device 25, the roadside indicator 28, the roadside wireless device 21, etc. are collectively referred to as lane equipment LE. The lane control device 10 also collects information indicating the operating status of each lane equipment LE (information indicating the number of times the sensor is turned on / off, the number of times the blocking bar is opened / closed, the number of communications, etc.).

[0028] Returning to FIG. 1, in the maintenance support system 100 of this embodiment, parts (also referred to as units) removed from lane equipment LE are stored in multiple maintenance areas MA-1, MA-2, ..., which are units for allocating maintenance work for lane equipment LE. A unit is a part that is a unit for replacement among the parts provided in the lane equipment LE. In the example shown in FIG. 1, the maintenance area MA-1 includes a maintenance office 71 and multiple toll gates TG including toll gate A TG-A, and the maintenance area MA-2 includes the maintenance office 71 and multiple toll gates TG including toll gate B TG-B. The maintenance office 71 includes a remote monitoring device 11 and a storage facility 114.

[0029] New parts for lane equipment LE, parts removed from lane equipment LE before or after repair, etc. are stored as spare parts SP in the storage 114. The spare parts SP are replacement parts stored as spares for parts of lane equipment LE that are in operation.

[0030] The remote monitoring device 11 is configured using a computer such as a personal computer, and includes functional blocks formed by a combination of hardware and software, such as an operation status collection unit 111, a spare part information registration unit 112, and an output unit 113. The operation status collection unit 111 collects information indicating the operation status of each lane device LE from each lane control device 10 via a communication line CL, and transmits the collected information to the maintenance support device 200. The spare part information registration unit 112 inputs information about each spare part SP in accordance with an input operation by an operator, and registers the information in a database 202 managed by the maintenance support device 200. The output unit 113 outputs information output by an output unit 203 included in the maintenance support device 200 by displaying, printing, or the like.

[0031] The maintenance support device 200 is configured using a computer such as a personal computer, and includes an acquisition unit 201, a database 202, and an output unit 203 as functional blocks configured by a combination of hardware and software. The maintenance support device 200 is a device that presents candidates for units to be reused when a unit removed from a lane equipment LE is to be reused in that lane equipment LE or another lane equipment LE. The maintenance support device 200 may be installed, for example, in one of the maintenance offices 71, or may be installed in a building separate from the maintenance office 71.

[0032] The acquisition unit 201 periodically (for example, once a day) acquires information indicating the operating status of units attached to lane devices LE and in operation from each lane control device 10. The database 202 includes a plurality of device management tables CT and a determination parameter table PT. In the example shown in FIG. 1, the plurality of device management tables CT are tables that record information about lane devices LE and the like for each maintenance area MA-1, MA-2, ..., and include a device management table CT-1 for maintenance area MA-1 and a device management table CT-2 for maintenance area MA-2. Each device management table CT stores information about units in operation and information about units removed from the lane devices LE. The determination parameter table PT stores conditions for determining whether to replace (rotate) a unit.

[0033] An example of the configuration of the device management table CT will be described with reference to Figures 3 to 6. Figures 3 and 4 show an example of the configuration of the device management table CT-1 in two separate figures. Figures 5 and 6 show an example of the configuration of the device management table CT-2 in two separate figures.

[0034] As shown in Figures 3 to 6, each record (row) in the equipment management table CT-1 and the equipment management table CT-2 stores information about units in operation and units that are not in operation as spare parts SPs, etc., for each unit. Each record includes multiple fields representing "No.", "Tollgate, etc.", "Lane, etc.", "Equipment," "Unit," "Identification Number," "Number of Days in Operation," "Number of Times in Operation," and "Number of Times Repaired." "No." indicates the record number. "Tollgate, etc." indicates the name of the tollgate, such as Tollgate A or Tollgate B, if the unit is in operation, and indicates that it is a spare part if it is not in operation. "Lane, etc." indicates the lane number within the tollgate if the unit is in operation, and indicates whether it is under repair if it is a spare part. If the unit is under repair, it cannot be used until the repair is completed. In this embodiment, "Number of Days in Operation" and "Number of Times in Operation" are information that indicates the operating status of each unit.

[0035] "Device" indicates the type (name) of the lane equipment LE to which the unit is attached. In the examples shown in Figures 3 to 6, a lane sign board 52, a departure controller 25, a crossing gate 26, and an axle detector 43 are exemplified. "Unit" indicates the type (name) of the unit. In the examples shown in Figures 3 to 6, an LED display unit is exemplified as a unit of the lane sign board 52, an opening / closing motor, a blocking bar, and a blocking bar broken recovery motor are exemplified as units of the departure controller 25, a blocking bar, an opening / closing motor, and an LED display unit are exemplified as units of the crossing gate 26, and a footboard is exemplified as a unit of the axle detector 43. "Identification number" is identification information that uniquely identifies each unit. "Number of operating days" indicates the number of days since each unit started operating (or since it was attached to the lane equipment LE). "Number of operations" indicates the number of times each unit has operated since it started operating (or since it was attached to the lane equipment LE). For example, the number of times a blocking rod breaks in the case of a blocking rod; the number of times a display signal is switched in the case of an LED display unit; the number of times a motor is started or reversed; and the number of times an axle passes in the case of a tread. The "number of repairs" indicates the number of repairs (maintenance) for each unit. In this embodiment, the "number of operating days" and "number of operations" are initialized to zero upon repair. However, they may be initialized to a value other than zero upon repair depending on the number of repairs.

[0036] In the example shown in Figure 3, for example, in the record with "No." A1, the "toll booth, etc." is Toll Booth A, the "lane, etc." is Lane 1, the "equipment" is Lane sign, the "unit" is LED display unit, the "identification number" is SN001, the "number of days in operation" is 900 days, the "number of times in operation" is 50,010, and the "number of times repaired" is 0. Also, for example, in the record with "No." A101, the "toll booth, etc." is a spare part, the "lane, etc." is not under repair, the "equipment" is Lane sign, the "unit" is LED display unit, the "identification number" is SN017, the "number of days in operation" is 0 days, the "number of times in operation" is 0, and the "number of times repaired" is 0. In this case, the unit with identification number SN017 is a new unit.

[0037] Next, an example of the configuration of the judgment parameter table PT will be described with reference to FIG. 7. The judgment parameter table PT is a table that represents the judgment conditions for whether or not to replace an operating unit with a spare part SP, for each pair of the type of lane equipment LE and the type of unit. In the example shown in FIG. 7, the judgment conditions are defined by a combination of the number of operating days and the number of times of operation. When the number of operating days or the number of times of operation of an operating unit exceeds (or becomes equal to or greater than) the value set in the judgment parameter table PT, the output unit 203 judges that the operating unit is to be replaced. For example, the record with "No." P1 indicates that the "equipment" is a lane signboard, the "unit" is an LED display unit, the judgment criterion for "number of operating days" is 1,000 days, and the judgment criterion for "number of times of operation" is 50,000 times.

[0038] Furthermore, when the operating status of a unit satisfies a predetermined condition, the output unit 203 extracts and outputs a unit that is a candidate for reuse from the database 202. The predetermined condition is, for example, that the "number of operating days" or "number of operating times" of an operating unit exceeds the "number of operating days" or "number of operating times" set in the judgment parameter table PT (corresponding to the second condition described later). For example, in the example shown in FIGS. 3 and 4, the operating times "50,010" of the LED display unit whose "No." is A1 in the device management table CT-1 exceeds the operating times "50,000" in the judgment condition for the LED display unit whose "No." is P1 in the judgment parameter table PT, so the output unit 203 determines that the operating status of the unit satisfies the predetermined condition. Then, the output unit 203 refers to the equipment management table CT-1 and extracts from the spare parts SP the LED display unit with "No." A101 and the LED display unit with "No." A109 that are candidates for replacement (or candidates for reuse), and further extracts the LED display unit with "No." A101 that has been repaired less frequently as a candidate unit for reuse.

[0039] The predetermined condition may include a first condition and a second condition corresponding to an operating condition in which the degree of deterioration is greater than that of the first condition. The output unit 203 may attempt to extract a reuse candidate from other operating units when the operating condition of a unit satisfies the first condition, and may attempt to extract a reuse candidate from a unit that has already been removed (or is new), as described above, when the operating condition of the unit satisfies the second condition. The first condition is a condition for leveling the operating condition, for example, by replacing a unit operating in a different lane with an operating unit that satisfies the first condition. For example, if the deterioration of a unit progresses depending on the number of times it is operated, the first condition may include a condition related to the number of times it is operated per hour.

[0040] For example, in the example shown in FIG. 3, the number of operations of the opening / closing motor of the launch control device with "No." A2 is 25,000 times after 500 operating days, and the number of operations per hour is 50 times per day. Furthermore, the number of operations per hour calculated from the "number of operating days" of 1,000 days and the "number of operations" of 50,000 times, which are the judgment conditions for the opening / closing motor of the launch control device set in the judgment parameter table PT, is 50 times per day, which matches the number of operations per hour of the opening / closing motor of the launch control device with "No." A2. Meanwhile, the number of operations per hour calculated from the "number of operating days" of 500 days and the "number of operations" of 500 times, which is the opening / closing motor of the launch control device with "No." A10, is 1 time per day. For example, if toll gate A has three or more lanes, it is estimated that if traffic in lanes 1 and 2 is temporarily blocked and the open / close motor of the launch control unit with "No." A2 (identification number "SN002") is replaced with the open / close motor of the launch control unit with "No." A10 (identification number "SN010"), the number of days until the open / close motor with identification number "SN002" exceeds the judgment condition set in the judgment parameter table PT can be extended. Also, the number of days until the open / close motor with identification number "SN010" exceeds the judgment condition set in the judgment parameter table PT can be shortened, and the operating conditions between the replaced units can be equalized. For example, the first condition can be set as a condition that the number of operations is equal to or greater than half (25,000 times) of the number of operations set in the judgment parameter table PT and equal to or greater than the number of operations per hour calculated from the number of operating days and number of operations set in the judgment parameter table PT (or the number of operations per hour exceeds a predetermined threshold value), and further, the number of operations per hour of the unit to be replaced is sufficiently smaller (for example, smaller by a predetermined percentage or more) than the number of operating days per hour of the unit that satisfies the first condition, and there is a certain margin in the number of operating days, etc., thereby making it possible to appropriately perform replacement between operating units to level out the operating status.

[0041] Furthermore, as in the present embodiment, in the case where units removed from lane devices LE are stored in each of a plurality of maintenance areas MA-1, MA-2, ..., which are units for allocating maintenance work for the lane devices LE, and the database 202 stores information on units in operation and information on units removed from the lane devices LE in association with the maintenance areas MA-1, MA-2, ..., the output unit 203 may extract and output units that are candidates for reuse from the database 202 based on the priority set for each maintenance area MA-1, MA-2, .... For example, replacement candidate units may first be extracted from within the same maintenance area MA-1, MA-2, ..., and if there are no replacement candidate units in the same maintenance area MA-1, MA-2, ..., a search may be made for replacement candidate units from spare parts SP stored in other maintenance areas MA-1, MA-2, ..., which are, for example, shorter in travel time or travel distance. In this case, the same maintenance areas MA-1, MA-2, ... have the highest priority, and the priorities of other maintenance areas MA-1, MA-2, ... are set to different values ​​depending on the travel time and travel distance. In this embodiment, for the maintenance area MA-1 which is the local area, the priority of the maintenance area MA-2 is set to the second highest value after the local area.

[0042] 3 to 6, for example, the operation count "70,001" of the circuit breaker opening / closing motor with "No." A6 in the equipment management table CT-1 for maintenance area MA-1 exceeds the operation count "70,000" of the circuit breaker opening / closing motor with "No." P2P6 in the judgment parameter table PT. In this case, the output unit 203 searches for replacement candidates in the equipment management table CT-1 for maintenance area MA-1. However, as shown in FIG. 4, it is assumed that all spare parts SP for circuit breaker opening / closing motors are currently under repair. In this case, the output unit 203 searches for replacement candidates, for example, for spare parts SP registered in the equipment management table CT-2 for maintenance area MA-2, which has the next highest priority. In the example shown in FIG. 6, the output unit 203 extracts the spare part SP for the circuit breaker opening / closing motor with "No." B106 in the equipment management table CT-2 as a replacement candidate.

[0043] Next, with reference to Fig. 8, an example of the operation of the maintenance support system 100 described with reference to Figs. 1 to 7 will be described. The processing shown in Fig. 8 is executed, for example, every day and for each maintenance area MA-1, MA-2, ... For example, in the processing for the maintenance area MA-1, the acquisition unit 201 acquires the latest information on the operating status (number of operating days and number of operating times) of each unit from each lane control device 10 in the maintenance area MA-1, and updates the contents of the equipment management table CT-1 (step S11). Note that the information on each spare part SP in the equipment management table CT-1 is updated as needed by the spare part information registration unit 112.

[0044] Next, the output unit 203 searches the equipment management table CT-1 for replacement targets for units between lanes, and extracts all replacement target units (units that satisfy the first condition) (step S12). Next, if there is at least one replacement target unit (step S13: YES), the output unit 203 searches the equipment management table CT-1 for replacement candidates that will be the replacement partners for each replacement target unit (step S14). Next, if there is at least one replacement candidate unit (step S15: YES), the output unit 203 outputs information indicating each replacement target and information indicating each replacement candidate, and outputs it from the output unit 113 (step S16).

[0045] If there is no replacement target (step S13: NO), if there is no replacement candidate (step S15: NO), or if replacement candidates have been output (step S16), the output unit 203 searches the equipment management table CT-1 for operating units (units that satisfy the second condition) that are to be replaced with the spare parts SP, and extracts all operating units that are to be replaced (step S17). Next, if the output unit 203 has extracted at least one operating unit that is to be replaced (step S18: YES), it searches the equipment management table CT-1 for spare parts SP that are replacement candidates (step S19). If replacement candidate spare parts SP have been extracted for all replacement target units (step S20: YES), the output unit 203 outputs information indicating each replacement target and information indicating each replacement candidate, outputs the information from the output unit 113 (step S23), and ends the processing shown in FIG. 8.

[0046] If there is even one replacement target unit for which no replacement candidate spare part SP has been extracted (step S20: NO), the output unit 203 searches for replacement candidate spare part SPs from the equipment management tables CT-2, ... of the other maintenance areas MA-2, ... (step S21). If replacement candidate spare part SPs have been extracted for all replacement target units (step S22: YES), the output unit 203 outputs information indicating each replacement target and information indicating each replacement candidate, and outputs the information from the output unit 113 (step S23), thereby ending the processing shown in FIG.

[0047] If there is any unit to be replaced for which no replacement candidate spare part SP has been extracted (step S22: NO), the output unit 203 outputs information indicating each replacement target and information indicating each replacement candidate or information indicating that no replacement candidate has been extracted, and outputs this from the output unit 113 (step S24), and the processing shown in Figure 8 is terminated.

[0048] On the other hand, if no operating units to be replaced are extracted (step S18: NO), the output unit 203 ends the processing shown in FIG.

[0049] (Action and effect) In the maintenance support system and maintenance support method configured as described above, when a unit (component) removed from a lane device LE (an example of "device" in the present disclosure) is reused in that device or another device, candidate units for reuse are presented. The maintenance support system and maintenance support method configured as described above periodically acquire information indicating the operational status of units currently attached to the lane device LE, and use a database 202 that stores information on currently operating units and information on units removed from the lane device LE. If the operational status of a unit satisfies a predetermined condition, candidate units for reuse are extracted from the database 202, and information indicating the extracted units is output. Therefore, the maintenance support system and maintenance support method of this embodiment enable appropriate selection of candidate units for reuse.

[0050] Furthermore, the predetermined conditions include a first condition and a second condition corresponding to an operating condition when the degree of deterioration is greater than that of the first condition (when the number of operating days or the number of operating times is greater), and when the operating condition of a unit satisfies the first condition, an attempt is made to extract a candidate for reuse from other operating units (for example, units operating in other lanes), and when the operating condition satisfies the second condition, an attempt is made to extract a candidate for reuse from units that have already been removed (spare parts SP). This configuration may enable the operating conditions of each unit to be leveled out.

[0051] Furthermore, if the units deteriorate in accordance with the number of times they are operated, the first condition may include a condition relating to the number of times they are operated per hour. With this configuration, the units can be rotated in accordance with the number of times they are operated per hour.

[0052] Furthermore, in the above configuration, units removed from lane equipment LE are stored for each of a plurality of maintenance areas MA-1, MA-2, ..., which are units for allocating maintenance work for the lane equipment LE, and the database 202 stores information on units in operation and information on units removed from the lane equipment LE, in association with the maintenance areas MA-1, MA-2, .... Then, based on the priority set for each maintenance area MA-1, MA-2, ..., units that are candidates for reuse are extracted from the database 202 and output. With this configuration, it is possible to appropriately extract units that are candidates for reuse.

[0053] (Other embodiments) Although the embodiments of the present disclosure have been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design modifications and the like are also included within the scope of the present disclosure. In the above embodiment, the conditions set in the judgment parameter table PT were constant regardless of the number of repairs, but this is not limited to this. For example, multiple values ​​that differ depending on the number of repairs may be set as conditions. Furthermore, the elements indicating the operating status are not limited to the number of operating days and the number of operating times, but may include other elements related to, for example, the operating temperature, ambient temperature, operating time, the number and magnitude of impacts (vibrations above a predetermined level), the number and magnitude of occurrences of (or occurrences of) overcurrent or overvoltage, etc.
