  An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of the positional relationship between the departure point, the destination, and each facility. In the present embodiment, the data collection device is mounted on a vehicle (moving body) for which facility maintenance is not originally intended, for example, a business vehicle. The data collection device collects facility maintenance data indicating the state of the facility and the appearance image of the facility while reciprocating with the business vehicle from the departure point to the destination irregularly. Here, the destination may be a destination at a different position each time the business vehicle is dispatched.

  The data collection device includes a communication device that wirelessly transmits and receives data, an imaging device that captures the appearance of the facility, a positioning (eg, Global Positioning System, GPS) device, and a route guidance (navigation) device.

  Each of the facilities 600-1 to 600-48 is a facility to be monitored, that is, a facility to be collected and facility imaging data. Here, each of the facilities 600-1 to 600-48 is located along the road. In addition, the facilities 600-1 to 600-48 are managed in a database in terms of their positions and data collection information. The facilities 600-1 to 600-48 may be managed for each facility, but each facility group in which a plurality of facilities are collected is managed by the facility maintenance data collection system. By managing the equipment for each equipment group, the equipment maintenance data collection system can prevent the travel route of the business vehicle from becoming more complicated than necessary.

  In FIG. 1, three facilities facing the same road in one section are grouped to form one facility group. As an example, in FIG. 1, each facility is classified into facility groups 700-1 to 700-16 and managed for each facility group.

  The route management system of the equipment maintenance data collection system (to be described later with reference to FIG. 3) travels on the road facing the equipment for which equipment maintenance data has not been collected based on the destination and the target arrival time. In this way, information representing the route on which the business vehicle travels is transmitted to the route guidance device (navigation device) of the business vehicle.

  The business vehicle travels on the road according to the routes (outward and return routes) received by the route guidance device from the route management system. Further, the data collection device compares the current position information of the business vehicle with the position information of the facility, and when the business vehicle approaches the facility, it collects facility maintenance data and performs appearance imaging. When the business vehicle returns to the departure place (returns to work), the data collection device registers the collected data in the equipment maintenance database of the equipment maintenance data collection system. The equipment maintenance system manages equipment maintenance data for each equipment and manages state changes and the like.

  FIG. 2 shows an outline of a method for defining a route. Since maintaining the equipment is not the original purpose of the business vehicle, when the route from the start point of the business vehicle to the destination is changed, it is necessary to prevent the travel route from being changed excessively. In order to prevent the travel route from being changed excessively, a route changeable number (threshold) that is the upper limit of the number of route changes is determined in advance. Here, when the business vehicle is dispatched, the position of the destination (for example, longitude and latitude) and the arrival target time are determined in advance.

  The route is determined based on the combination of the positions of the facility groups designated by the passing point designation device (described later with reference to FIGS. 3 and 4) as a target for collecting data and the like. And will be described later. In this way, since the route is determined based on the equipment group, the number of parameters input to the route search device that searches for the route is reduced, so the estimated time required for calculating the route is shortened. Is done. The final route (final route) on which the business vehicle travels is selected by the passing point designation device based on the number of routes that can be changed from among a plurality of routes calculated by the route search device.

  In FIG. 2, it is assumed that an equipment group 700-a including equipments 600-a to 600-c faces a path 3100. The starting point 710-a is a starting point of a route in a section where the equipment group 700-a and the route 3100 face each other. The end point 720-a is the end point of the route in the section where the equipment group 700-a faces the route 3100. In addition, it is assumed that the facilities 600-a to 600-c of the facility group 700-a facing the path 3100 have passed 100 days since the previous monitoring (data collection or the like).

  In addition, it is assumed that the facility group 700-b including the facilities 600-d to 600-g faces a route 3000 (basic route) that connects the starting point and the destination in the shortest time. For example, the route 3000 is a route determined for a main road. The starting point 710-b is the starting point of the route in the section where the equipment group 700-b and the route 3000 face each other. The end point 720-b is the end point of the route in the section where the equipment group 700-b and the route 3000 face each other. Further, it is assumed that the facilities 600-d to 600-g of the facility group 700-b facing the route 3000 have passed five days since the previous monitoring.

  In addition, it is assumed that the facility group 700-c including the facilities 600-h to 600-j faces the path 3200. The starting point 710-c is the starting point of the route in the section where the equipment group 700-c and the route 3200 are facing. The end point 720-a is the end point of the route in the section where the equipment group 700-a faces the route 3100. Further, it is assumed that the facilities 600-h to 600-j of the facility group 700-c facing the route 3200 have passed 60 days since the previous monitoring.

  Here, the priority order of each route is determined according to the equipment status (priority information) for each equipment based on the collected equipment maintenance data. Further, the priority of each route may be set such that the route 3100 has the highest priority (priority) and the route 3000 has the lowest priority in the descending order of the number of days since the previous monitoring. Moreover, this priority may be valid only when the number of days elapsed since the previous monitoring exceeds a certain period (for example, 30 days).

  Further, T0 is an estimated time estimated to be necessary for the vehicle to travel from the departure point along the route 3000 (basic route) to the destination. Further, T1 is an estimated time estimated to be necessary for the vehicle to travel from the starting point along the route 3100 to the destination. Further, T2 is an estimated time estimated to be necessary for the vehicle to travel from the departure point along the route 3200 to the destination. In this case, the increment of the route 3100 with respect to the route 3000 which is the basic route (for example, the shortest route) is (T1−T0) / T0 × 100 [%]. By setting an upper limit value (threshold value) for increments with respect to the basic route in advance, a final route (final route) that falls within a range that does not exceed the upper limit value (below the upper limit value) is determined.

  The upper limit value (threshold value) may be an upper limit value of the expected time increment or may be an upper limit value of the predicted time itself. The routes may be compared based on the expected time or may be compared based on the route distance.

Next, the configuration of the equipment maintenance data collection system will be described.
FIG. 3 shows the configuration of the equipment maintenance data collection system. The equipment maintenance data collection system includes a route management system 2000, equipment database 300, and equipment maintenance apparatus 400. The equipment database 300 stores information about equipment (for example, information representing the position of equipment), and outputs information about equipment to the route management system 2000.

  The equipment maintenance apparatus 400 includes an equipment maintenance database 410. The equipment maintenance apparatus 400 acquires the equipment maintenance data collected by the data collection apparatus 530 from the data collection apparatus 530 mounted on the business vehicle 500 and stores the obtained equipment maintenance data in the equipment maintenance database 410. When the equipment maintenance data table stored in the equipment maintenance database 410 is updated by the equipment maintenance data acquired from the data collection device 530, the equipment maintenance apparatus 400 informs the route management system 2000 that the equipment maintenance data table has been updated. Notice.

  The route management system 2000 includes a passing point designation device 1000 and a route search device 200. The passing point designation device 1000 includes a monitoring target facility management database 1100. In the passing point designation device 1000, information indicating the departure location (latitude, longitude), the destination location (latitude, longitude), and the arrival target time are received from the route guidance device 540 via an input device having an input screen. Entered.

  The passing point designation device 1000 determines a facility for which facility maintenance data and the like are collected based on the departure location, the destination location, and the arrival target time. The passing point designating apparatus 1000 outputs information (for example, latitude and longitude) indicating the position of the equipment that is determined as a target for collecting equipment maintenance data and the like to the route search apparatus 200 as the passing point position. Further, the passing point specifying device 1000 acquires information representing the route calculated (searched) by the route search device 200 from the route search device 200.

  The passing point designating device 1000 also uses the data registered in the monitoring target table stored in the monitoring target facility management database 1100 to determine the final route traveled by the business vehicle 500 among the routes calculated by the route searching device 200. The route search apparatus 200 selects from a plurality of routes searched. The passing point designation device 1000 outputs information representing the selected route to the route guidance device 540 mounted on the business vehicle 500 (travel route instruction).

  Information indicating the passing point position (via point position) is input from the passing point specifying device 1000 to the route search device 200. The route search device 200 calculates (searches) a route along which the business vehicle 500 travels based on information representing the passing point position, and outputs information representing the calculated route to the passing point specifying device 1000.

  The business vehicle (moving body) 500 includes a communication device 510, an imaging device 520, a data collection device 530, and a route guidance device 540. The business vehicle 500 travels on the road in response to an operation instruction from the driver. Here, the driver causes the business vehicle 500 to travel along the route guided by the route guidance device 540.

  The route guidance device 540 receives an operation input by the driver, and outputs information indicating the input departure location, destination location, and arrival time to the passing point designation device 1000. In addition, the route guidance device 540 receives information representing the route from the passing point designation device 1000, and guides the driver the route designated by the received information representing the route. Here, the route guidance device 540 measures the position of the device itself, and notifies the driver and the data collection device 530 of the positioning result. The route guidance device 540 measures the position of its own device, for example, by receiving radio waves from a satellite.

  The imaging device 520 captures the appearance of each facility and causes the data collection device 530 to store the captured image. The communication device 510 wirelessly receives facility maintenance data from the facility via the communication device provided in each facility, and stores the received facility maintenance data in the data collection device 530.

  When the data collection device 530 approaches the facility based on the location information notified from the route guidance device 540 and the facility location information stored in advance, the data collection device 530 performs facility maintenance via the communication device 510. Receive data from the facility. In addition, the data collection device 530 stores the position information notified from the route guidance device 540 and the appearance image of the facility imaged by the imaging device 520 when the data collection device 530 approaches the facility as facility maintenance data. .

  The facility 600a includes a sensor 610, a storage unit 620, and a communication unit 630. For example, the sensor 610 senses temperature and humidity and causes the storage unit 620 to store the sensing data. The storage unit 620 stores predetermined facility maintenance data and sensing data. The communication unit 630 wirelessly transmits the facility maintenance data and sensing data stored in the storage unit 620 to the communication device 510 mounted on the business vehicle 500 approaching the facility 600a. The same applies to other facilities (such as facility 600b).

Next, the configuration of the passing point designating device and the relationship with other devices will be described.
FIG. 4 shows the configuration of the passing point designation device and the relationship with other devices. The passing point designation device 1000 transmits and receives predetermined data between the input device 800, the route search device 200, the equipment database 300, the equipment maintenance device 400, the equipment maintenance database 410, and the output device 900.

  The equipment maintenance apparatus 400 includes an equipment maintenance database 410.

Remember me. In addition, the equipment maintenance apparatus 400 stores a number (record number) for specifying a record in which the equipment maintenance data is registered in the equipment maintenance database 410. Further, the equipment maintenance apparatus 400 notifies the passing point designation apparatus 1000 that the equipment maintenance data table (described later with reference to FIG. 7) stored in the equipment maintenance database 410 has been updated. The equipment maintenance apparatus 400 acquires information about equipment (for example, equipment ID, which is equipment identification information) from the equipment database 300, and stores the acquired information in the equipment maintenance database 410 as equipment maintenance data.

  The equipment maintenance database 410 stores a management data table. FIG. 5 shows an example of a management data table stored in the equipment maintenance database. Items in the management data table include an equipment ID, a previous data collection date, a data collection state, and an equipment status. The equipment ID is equipment identification information. The previous data collection date is the previous date when the equipment maintenance data was collected. The data collection state indicates whether or not the equipment maintenance data has not been acquired (not collected). The equipment status is priority order information indicating a priority monitoring level (normal, priority monitoring 1, priority monitoring 2, priority monitoring 3, abnormality, etc.). These items are associated with each other and registered in the management data table. For example, “other data” representing the humidity of the facility, the temperature of the facility, the type of the facility, and the like may be further added to the items of the management data table.

  The facility maintenance database 410 stores a record number table. FIG. 6 shows an example of a record number table stored in the equipment maintenance database. Items in the record number table include equipment ID, previous data collection date, and record number. The previous data collection date is the date and time when the equipment maintenance data was collected last time.

The equipment maintenance data table is managed separately for each record. The items in the equipment maintenance data table include an address, year, month, day, hour, data 1 and data 2. The address represents a relative address where facility maintenance data is registered in the facility maintenance database 410. For example, 24 pieces of equipment maintenance data (for example, temperature data) are registered in the equipment maintenance data table as data for one day. For example, the equipment maintenance data (for example, temperature data) for 180 days is registered in the equipment maintenance data table as one record.

  The year, month, day, and hour represent the year, month, day, and hour when the equipment maintenance data was collected, respectively. Data 1 and data 2 represent the collected facility maintenance data by type (for example, temperature and humidity). In the equipment maintenance database, data “***” registered in data 1 and data 2 indicates that the equipment maintenance data that should have been registered at the address has not been acquired. These items are associated with each other and registered in the equipment maintenance data table.

  Returning to FIG. 4, the description of the configuration of the passing point designating device will be continued. The basic route calculation unit 1200 acquires information representing a departure location (latitude, longitude), a destination location (latitude, longitude), and an arrival target time from an input device 800 having an input screen. The basic route calculation unit 1200 inputs information representing the departure location, the destination location, and the arrival target time to the route search device 200. The basic route calculation unit 1200 causes the route search device 200 to calculate the passing point position (latitude, longitude) and the predicted time T0 based on information indicating the departure point position, the destination position, and the arrival target time. Here, the estimated time T0 is the time estimated to be necessary for movement from the departure place to the destination when traveling along the basic route.

  The basic route calculation unit 1200 acquires the passing point position and the expected time T0 from the route search device 200. Further, the basic route calculation unit 1200 uses the acquired passing point position, estimated time T0, departure point position, and destination position as data of a basic route table (described later with reference to FIGS. 13 and 14). The data is stored in the unit 1250 (see FIG. 4). Here, the basic route calculation unit 1200 causes the basic route table unit 1250 to store a basic route having the starting point position as the first passing point position and the destination position as the final passing point position.

  The basic route table unit 1250 (see FIG. 4) stores basic data and passing point data of the basic route table. FIG. 13 shows an example of basic data of the basic route table. The basic data items in the basic route table include a departure location, a destination location, and an estimated time. The departure location is the location of the departure location where the business vehicle 500 (see FIG. 3) is dispatched (for example, the location where the equipment maintenance device 400 is installed). The destination position is the position of the destination where the business vehicle 500 is dispatched (for example, a customer). These items are associated with each other and registered in the basic route table.

  FIG. 14 shows an example of passing point data in the basic route table. The items of passing point data in the basic route table include a passing point ID and a passing point position. The passing point ID is identification information for identifying an intersection and a corner position where the business vehicle 500 (see FIG. 3) can travel. The passing point position is information indicating the position of an intersection and a corner associated with the passing point ID.

  The peripheral equipment extraction unit 1300 (see FIG. 4) acquires the passing point position from the basic route table (see FIG. 14) of the basic route table unit 1250. The peripheral facility extraction unit 1300 calculates the distribution of the peripheral region of the route passing through each passing point based on the acquired passing point position. The peripheral equipment extraction unit 1300 is based on the equipment ID registered in the equipment position table (see FIG. 8) stored in the equipment database 300 (see FIG. 4), and the equipment position (latitude) is the position information of each equipment. , Longitude). The peripheral equipment extraction unit 1300 extracts the position of the equipment in the peripheral area based on the equipment position of each equipment and the calculated distribution of the peripheral area.

FIG. 15 shows a method of extracting the position of equipment located in the peripheral area of the route. When the business vehicle 500 passes the coordinates (x1, y1) and coordinates (x2, y2) of two passing points on the route calculated by the route search device 200, the following is considered.
The straight line f1 (x) connecting the two passing points is

  f1 (x) = (y2-y1) / (x2-x1) * x + (x1 * y2 + x2 * y1) / (x1-x2) (1)

  It becomes. Further, the straight line is parallel to the straight line f1 (x), and is a straight line between the straight lines f2 (x) and f3 (x) separated from the straight line f1 (x) by a predetermined interval r, and the passing point (x1, y1). A straight line f5 (x) orthogonal to f1 (x) and a straight line f4 (x) orthogonal to the straight line f2 (x) at the passing point (x2, y2) are determined.

  Further, a region surrounded by the straight line f2 (x), the straight line f3 (x), the straight line f4 (x), and the straight line f5 (x) is defined as a peripheral region in FIG. Further, in order to fill a gap between adjacent peripheral regions, a circular region having a radius r centering on the passing point (x1, y1) is also included in the peripheral region.

Therefore, the surrounding area is
y <f2 (x), y> f3 (x), y> f4 (x), y <f5 (x) (2)
as well as,
(x−x1) ² + (y−y1) ² <r ² (3)
It is expressed.

  The peripheral equipment extraction unit 1300 (see FIG. 4) extracts the position of equipment located in the peripheral area of the route. The peripheral facility extraction unit 1300 stores the facility ID indicating the extracted facility in the peripheral facility table unit 1350 as data of the peripheral facility table.

  The peripheral equipment table unit 1350 stores data of the peripheral equipment table. FIG. 16 shows an example of the peripheral equipment table. The items in the peripheral equipment table include equipment IDs for identifying equipment in the peripheral area of the route.

  The target facility extraction unit 1400 acquires the facility ID from the peripheral facility table stored in the peripheral facility table unit 1350. In addition, the target facility extraction unit 1400 has a monitoring target table (FIG. 10) in which the monitoring target facility management database 1100 (see FIG. 4) stores the data collection interval and data collection instruction associated with the acquired facility ID. To get from).

  The target equipment extraction unit 1400 indicates that the data collection instruction of the equipment ID acquired from the peripheral equipment table of the peripheral equipment table unit 1350 among “instructed”, “target”, or “non-target” that the data collection instruction can take is “target Is determined. When the data collection instruction associated with the acquired facility ID is “target”, the target facility extraction unit 1400 associates the acquired facility ID with the data collection interval and stores them in the buffer.

  The target facility extraction unit 1400 determines whether or not there is a facility ID that has not been acquired in the peripheral facility table unit 1350 (remains). When there is no equipment ID that has not been acquired in the peripheral equipment table unit 1350, the target equipment extraction unit 1400 arranges the data collection intervals stored in the buffer in order of increasing interval.

  The target facility extraction unit 1400 acquires the facility ID from the buffer. In addition, the target facility extraction unit 1400 acquires the group ID associated with the facility ID from the facility group table (see FIG. 11) stored in the monitoring target facility management database 1100. The target facility extraction unit 1400 stores the acquired group ID in the target facility table unit 1450. Here, when the group IDs overlap, that is, when the group ID is already stored in the target equipment table, the target equipment extraction unit 1400 does not newly store the group ID.

  The target facility extraction unit 1400 determines whether or not the buffer is empty. In addition, the target facility extraction unit 1400 determines whether or not processing has been performed up to the path changeable number, for example, whether or not the number of acquired group IDs is greater than or equal to the path changeable number. When the buffer is empty or when processing is performed up to the number of possible route changes, the target facility extraction unit 1400 calls the change route calculation unit 1500 (see FIG. 4).

  The target equipment table unit 1450 stores the target equipment table. FIG. 17 shows an example of the target equipment table. In the target equipment table, a priority order and a group ID are associated and registered.

  The change route calculation unit 1500 (see FIG. 4) obtains a predetermined number (number of route changeable) group IDs in descending order of priority from the target facility table stored in the target facility table unit 1450. To do. In the changed route calculation unit 1500, the monitoring target facility management database 1100 stores the start point (latitude, longitude) and end point (latitude, longitude) of the route in the section where the facility group indicated by the group ID and the route face each other. From the group position table (see FIG. 12).

  FIG. 18 shows an example of priorities used when calculating a route. Here, since the number of equipment groups is three (equipment groups 700-a to 700-c), the number of possible route changes is three. Further, the weight of the equipment group 700-a is set to 4 when the start point 710-a and the end point 720-a are designated as the passing point positions. Further, when the start point 710-b and the end point 720-b are designated as passing point positions, the weight of the equipment group 700-b is set to 1. Further, the weight of the facility group 700-c is set to 2 when the start point 710-c and the end point 720-c are designated as the passing point positions. In other cases, the weight of the equipment group is zero.

  In this case, the route that passes through all the equipment groups 700-a to 700-c has a weight of 7, and has the highest priority. Similarly, a route that passes only through the equipment groups 700-a and 700-c has a weight of 6, and is the route with the second highest priority. Hereinafter, each route is calculated by the route search device 200 in descending order of route priority.

  If the increment of the predicted time of the route with the highest priority does not exceed the predetermined upper limit (threshold value) with respect to the predicted time T0 of the basic route, the route is finally determined as a route. The If the increase in the estimated time of the route with the highest priority exceeds a predetermined upper limit value, the increase in the estimated time of the route with the second highest priority with respect to the expected time T0 of the basic route. Is determined to exceed a predetermined upper limit value. If the expected time increment of the route with the second highest priority does not exceed the predetermined upper limit value, the route is finally determined. Hereinafter, the final route is determined by making the same determination.

  The changed route calculation unit 1500 (see FIG. 4) includes the start point position of the route in the section where each group (in FIG. 2, the facility groups 700-a, 700-b, and 700-c) faces each route, and By inputting the end point position into the route search device 200 (see FIG. 4) as a pass point position, the route search device 200 calculates another pass point position of the changed route and the expected time Tn. The changed route calculation unit 1500 stores the group ID, the passing point position, and the estimated time Tn in the changed route table unit 1550 (see FIG. 4).

  The changed route table unit 1550 stores basic data of the changed route table and passing point data of the changed route table. FIG. 19 shows an example of basic data of the change path table. The items of basic data in the change route table include a departure position, a destination position, and an estimated time T0. These items are associated with each other and registered in the change route table. Here, n is the number of paths that can be changed.

  FIG. 20 shows an example of passing point data in the changed route table. The items of passing point data in the changed route table include a passing point ID and a passing point position. Here, n is the number of paths that can be changed.

  The route determination unit 1600 acquires the expected time Tn from the basic data of the changed route table (see FIG. 19) stored in the changed route table unit 1550. Further, the route determination unit 1600 determines whether or not the acquired predicted time Tn is equal to or less than the upper limit value (threshold value). When the acquired predicted time Tn is less than or equal to the upper limit (threshold value), the route determination unit 1600 stores the changed route table (FIG. 19 and FIG. 19) in which the changed route table unit 1550 stores the group ID, the passing point position, and the predicted time Tn. (See FIG. 20).

  The route determination unit 1600 stores the acquired group ID, passing point position, and estimated time Tn in the final route table unit 1650 (see FIG. 4) as data of the final route table. In this way, the route determination unit 1600 designates a facility group or facility for which data and the like are to be collected.

  The route determination unit 1600 acquires the equipment ID associated with the acquired group ID from the equipment group table (see FIG. 11) stored in the monitoring target equipment management database 1100. In addition, the route determination unit 1600 changes the data collection instruction associated with the acquired facility ID to “instructed” in the monitoring target table (see FIG. 10) stored in the monitoring target facility management database 1100.

  The final route table unit 1650 stores a final route table. Here, the final route table is a data table representing a route (final route) that is finally transmitted to the data collection device 530 as a route on which the business vehicle 500 (see FIG. 3) travels. The configuration of the final route table is the same as that of the basic route table (see FIGS. 13 and 14).

  The monitoring target equipment update unit 1700 refers to the equipment maintenance data table (see FIG. 7) stored in the equipment maintenance database 410, and among the equipment maintenance data whose last data collection date is today (collected this time) It is determined whether the maintenance data has not been acquired ("***" is registered in the equipment maintenance data table). When the equipment maintenance data has not been acquired, the monitoring target equipment update unit 1700 refers to the record number table (see FIG. 6) stored in the equipment maintenance database 410 and should register the equipment maintenance data that has not been acquired. The equipment ID associated with the record number of the record that was was acquired.

  Also, the monitoring target facility update unit 1700 refers to the management data table (see FIG. 5) stored in the facility maintenance database 410, and sets the data collection state associated with the acquired facility ID as “not yet acquired”. sign up.

  Further, the monitoring target equipment update unit 1700 refers to the management data table stored in the equipment maintenance database 410, and sets the equipment status (priority information) for each equipment based on the equipment maintenance data whose last data collection date is today. judge.

  Here, an example of a method for determining the equipment status will be described. The monitoring target facility update unit 1700 has one or more types of facility maintenance data (data 1 and data 2) registered in the facility maintenance data table (see FIG. 7) and signs that are different from normal (an example is illustrated in FIG. If the equipment maintenance data is found in the equipment maintenance data, the equipment status is updated for each equipment.

  When the sign indicates an abnormality (for example, the value of the equipment maintenance data is out of a predetermined range), the monitored equipment update unit 1700 determines the equipment status of the equipment as abnormal. In addition, a notification that the equipment status is abnormal is output from the monitored equipment update unit 1700 to the output device 900 or the like so that the equipment maintenance vehicle or the like can immediately confirm the equipment whose equipment status is determined to be abnormal.

  In addition, if the sign does not indicate an abnormality (for example, the value of the equipment maintenance data is within a predetermined range) but a sign different from the normal is found in the equipment maintenance data, the monitoring target equipment update unit 1700 The equipment statuses of the equipment are defined as priority monitoring 1, priority monitoring 2, and priority monitoring 3 in order of increasing signs that are different from normal.

  Moreover, the monitoring target equipment update unit 1700 associates a data collection interval, which is a time interval for collecting equipment maintenance data, according to the equipment status. For example, when it is determined that the facility maintenance data is collected from all facilities (see FIG. 1) within 180 days, the monitoring target facility update unit 1700 sets the data collection interval “within 90 days” to the priority monitoring 1. Associate. Also, the monitoring target equipment update unit 1700 associates the data collection interval “within 60 days” with the priority monitoring 2. Also, the monitoring target equipment update unit 1700 associates the data collection interval “within 30 days” with the priority monitoring 3. Moreover, the monitoring target equipment update unit 1700 associates the data collection interval “within 0 days (immediate confirmation)” with the equipment status “abnormal”.

<When equipment maintenance data (sensing data) is data representing the internal temperature and outside temperature of equipment>
The monitoring target facility update unit 1700 calculates a comparison result (difference) between the outside air temperature data or threshold value determined as a target to be compared and the collected internal temperature data, and based on the calculated comparison result, Equipment status (priority information).

  For example, the monitoring target equipment update unit 1700 determines the equipment status (see FIG. 5) for each equipment based on 24 pieces of equipment maintenance data collected every hour. FIG. 21 shows an example of the internal temperature and the outside air temperature of a road transformer that is an example of equipment. Here, the vertical axis represents temperature. The horizontal axis represents time.

When the internal temperature exceeds the upper management limit line (for example, 60 degrees Celsius) ten times or more, the monitoring target facility update unit 1700 determines the facility status of the facility as the priority monitoring 1.
When the internal temperature exceeds the upper control limit line for 1 day or more and less than 7 days, the monitoring target facility update unit 1700 determines the facility status of the facility as priority monitoring 2.
In addition, when the internal temperature exceeds the upper control limit line for 7 consecutive days or more and the internal temperature at the latest date and time when the facility maintenance data is collected (see FIG. 7) does not exceed the upper control limit line, The monitoring target equipment update unit 1700 determines the equipment status of the equipment as priority monitoring 3.
If the internal temperature exceeds the upper control limit line for 7 consecutive days or more and the internal temperature at the latest date and time when the equipment maintenance data is collected exceeds the upper control limit line, the monitored equipment update unit 1700 Defines the equipment status of the equipment as abnormal.

Further, when the internal temperature falls below the lower control limit line (for example, 0 degrees Celsius) for 10 times or more, the monitoring target equipment update unit 1700 determines the equipment status of the equipment as priority monitoring 1.
When the internal temperature falls below the lower control limit line for 1 day or more and less than 7 days, the monitoring target equipment update unit 1700 determines the equipment status of the equipment as priority monitoring 2.
Also, if the internal temperature is below the lower control limit line for 7 consecutive days or more and the internal temperature at the latest date and time when facility maintenance data was collected (see Figure 7) is not below the lower control limit line The equipment update unit 1700 determines the equipment status of the equipment as priority monitoring 3.

If the internal temperature is lower than the outside air temperature for seven consecutive days or more and the internal temperature at the latest date and time when the equipment maintenance data is collected is lower than the outside air temperature, the monitoring target equipment update unit 1700 Define the status as abnormal.
When the internal temperature falls outside a predetermined limit range (for example, -20 to +70 [degrees]), the monitoring target equipment update unit 1700 determines that the equipment status of the equipment is abnormal.

<When equipment maintenance data (sensing data) is data representing the internal humidity and external humidity of the equipment>
The monitoring target facility update unit 1700 calculates a comparison result (difference) between the outside air humidity data or threshold value determined as a target to be compared and the collected internal humidity data, and on the basis of the calculated comparison result, Equipment status (priority information).

  For example, the monitoring target equipment update unit 1700 determines the equipment status (see FIG. 5) for each equipment based on 24 pieces of equipment maintenance data collected every hour. FIG. 22 shows an example of internal humidity and external humidity of a road transformer that is an example of equipment. Here, the vertical axis represents humidity. The horizontal axis represents time.

When the internal humidity exceeds the upper control limit line (for example, 90 [%]) for 1 day or more and less than 7 days, the monitoring target facility update unit 1700 determines the facility status of the facility as priority monitoring 1.
When the internal humidity exceeds the upper control limit line for 7 consecutive days or more and less than 14 days, the monitoring target facility updating unit 1700 determines the facility status of the facility as priority monitoring 2.
When the internal humidity exceeds the upper control limit line for 14 consecutive days or more and less than 21 days, the monitoring target facility updating unit 1700 determines the facility status of the facility as priority monitoring 3.
If the internal humidity exceeds the upper control limit line for 21 consecutive days or more, and the internal humidity at the latest date and time when the facility maintenance data is collected (see FIG. 7), The monitoring target equipment update unit 1700 determines that the equipment status of the equipment is abnormal.

Further, when the internal humidity falls below the outside air humidity 10 times or more, the monitoring target equipment update unit 1700 determines the equipment status of the equipment as the priority monitoring 1.
When the internal humidity falls below the outside air humidity for 1 day or more and less than 7 days, the monitoring target facility update unit 1700 determines the facility status of the facility as priority monitoring 2.
In addition, when the internal humidity is lower than the outside air humidity for seven consecutive days or more and the internal humidity at the latest date and time when the facility maintenance data is collected (see FIG. 7) is not lower than the outside air humidity, the monitored equipment update unit 1700 Defines the equipment status of the equipment as priority monitoring 3.
If the internal humidity is lower than the outside air humidity for 7 consecutive days or more and the internal humidity at the latest date and time when the equipment maintenance data is collected is lower than the outside air humidity, the monitoring target equipment update unit 1700 Define the status as abnormal.

<When equipment maintenance data is data representing the appearance of equipment>
The monitoring target facility update unit 1700 determines the facility status (priority information) for each facility based on the tendency indicated by the collected appearance data of the plurality of facilities.

  For example, the monitoring target facility update unit 1700 sets the facility status (see FIG. 5) for each facility based on one point of facility maintenance data (image data) representing the appearance of the facility imaged every six months. Determine. FIG. 23 shows an example of the inclination of a utility pole, which is an example of equipment. Here, the vertical axis represents the inclination [degree] of the utility pole with respect to the installation direction (vertical direction). The horizontal axis represents the date.

When the inclination of the utility pole is increased 7 times or less and less than 14 times and the inclination of the utility pole is less than 5 degrees, the monitoring target equipment update unit 1700 determines the equipment status of the equipment as priority monitoring 1.
Further, when the inclination of the utility pole increases continuously 14 times or more and the inclination of the utility pole is less than 5 [degrees], the monitoring target equipment update unit 1700 determines the equipment status of the equipment as the priority monitoring 2.
When the inclination of the utility pole is not less than 5 [degrees] and less than 10 [degrees], the monitoring target facility update unit 1700 determines the facility status of the facility as priority monitoring 2.
When the inclination of the utility pole is 10 [degrees] or more and less than 20 [degrees], the monitoring target facility update unit 1700 determines the facility status of the facility as priority monitoring 3.
Moreover, when the inclination of the utility pole is 20 [degrees] or more, the monitoring target equipment update unit 1700 determines that the equipment status of the equipment is abnormal.
The above is an example of a method for determining the equipment status.

  Returning to FIG. 4, the description of the configuration of the passing point designating device will be continued. The monitoring target facility update unit 1700 determines whether or not the determined facility status includes at least one of abnormality and priority monitoring 1 to 3. When the determined equipment status includes at least one of abnormality and priority monitoring 1 to 3, the monitored equipment update unit 1700 displays the equipment status of the equipment in the management data table stored in the equipment maintenance database 410. To register the determined equipment status. On the other hand, when the determined equipment status includes neither abnormality nor priority monitoring 1 to 3, the monitoring target equipment update unit 1700 sets the equipment status of the equipment in the management data table stored in the equipment maintenance database 410 to “ Register “Normal”.

  Moreover, the monitoring target equipment update unit 1700 acquires the equipment ID whose last data collection date is today from the management data table (see FIG. 5) stored in the equipment maintenance database 410. Moreover, the monitoring object equipment update part 1700 determines whether the equipment ID whose last data collection date is today is acquired. When the equipment ID whose last data collection date is today can be acquired, the data collection state and the equipment status associated with the equipment represented by the acquired equipment ID are acquired from the management data table stored in the equipment maintenance database 410.

  Also, the monitoring target equipment update unit 1700 refers to the management data table stored in the equipment maintenance database 410 and determines whether or not the acquired equipment status is “normal”. When the acquired equipment status is not “normal”, the monitoring target equipment updating unit 1700 determines which of the priority monitoring 1 to 3 is the acquired equipment status.

  When the acquired equipment status is priority monitoring 1, the monitoring target equipment update unit 1700 acquires the information in the monitoring target table (see FIG. 10) stored in the monitoring target equipment management database 1100 (see FIG. 4). The data collection interval associated with the equipment ID is registered as a value (number of days) “90”.

The interval is registered as a value (number of days) “30”.

  The monitoring target facility updating unit 1700 changes the data collection instruction of the monitoring target table (see FIG. 10) stored in the monitoring target facility management database 1100 to “not applicable”. Also, the monitoring target facility update unit 1700 updates each data item of the monitoring target table stored in the monitoring target facility management database 1100.

  When the acquired equipment status is “normal”, the monitoring target equipment update unit 1700 determines whether or not the acquired data collection state is “not acquired”. When the acquired data collection state is not “not acquired”, the monitoring target facility update unit 1700 receives a data collection instruction for the monitoring target table (see FIG. 10) stored in the monitoring target facility management database 1100. Change to “Not applicable”. Furthermore, the monitoring target facility update unit 1700 registers the value (number of days) “0” as the data collection interval of the monitoring target table stored in the monitoring target facility management database 1100.

  The timer 1750 transmits a trigger signal to the monitoring target equipment update unit 1700 at a predetermined time. Here, the predetermined time is, for example, 3 am every day.

  The output device 900 stores information (departure location, destination location, and passage location) indicating the final route on a route guidance device 540 (see FIG. 3) mounted on the outgoing business vehicle 500, a storage medium or Transmit via a communication line.

The basic route calculation unit 1200 inputs information indicating the departure location, the destination location, and the arrival target time to the route search device 200 (see FIG. 4). The basic route calculation unit 1200 causes the route search device 200 to calculate the passing point position (latitude, longitude) and the predicted time T0 based on the information indicating the departure point position, the destination position, and the arrival target time (step S4). .

  The basic route calculation unit 1200 acquires the passing point position and the expected time T0 from the route search device 200 (step S5). In addition, the basic route calculation unit 1200 uses the acquired passing point position, predicted time T0, departure point position, and destination position as data of the basic route table (see FIGS. 13 and 14), and the basic route table unit 1250 ( (See FIG. 4). Here, the basic route calculation unit 1200 stores the departure point position as the first passing point position and the destination position as the final passing point position in the basic route table unit 1250 (step S6). The basic route calculation unit 1200 calls the peripheral facility extraction unit 1300 (see FIG. 4) (step S7).

  FIG. 26 is a flowchart showing an operation procedure of the peripheral equipment extraction unit when extracting the positions of equipment located around the route. The peripheral facility extraction unit 1300 acquires the passing point position from the basic route table (see FIG. 14) of the basic route table unit 1250 (step S8). The peripheral facility extraction unit 1300 calculates the distribution of the peripheral area of the route passing through each passing point based on the acquired passing point position (step S9).

  In addition, the peripheral equipment extraction unit 1300 is equipment location that is location information of each equipment based on the equipment ID registered in the equipment location table (see FIG. 8) stored in the equipment database 300 (see FIG. 4). Get (latitude, longitude). The peripheral equipment extraction unit 1300 extracts the position of the equipment in the peripheral area of the route based on the equipment position of each equipment and the calculated distribution of the peripheral area (step S10). The peripheral equipment extraction unit 1300 stores the equipment ID indicating the extracted equipment in the peripheral equipment table unit 1350 (see FIG. 4) as data of the peripheral equipment table (see FIG. 16) (step S11).

  The peripheral equipment table unit 1350 determines whether or not there is a passing point position that is not used for calculation of the peripheral region (step S12). When there is a passing point position that is not used for calculation of the peripheral region (step S12—Yes), the processing of the peripheral facility table unit 1350 returns to step S8. On the other hand, when there is no passing point position that is not used for calculation of the surrounding area (step S12—No), the surrounding equipment table unit 1350 calls the target equipment extracting unit 1400 (see FIG. 4) (step S13).

  FIG. 27 is a flowchart showing the operation procedure of the target facility extraction unit when extracting the position of the target facility for collecting data and the like. The target facility extraction unit 1400 acquires the facility ID from the peripheral facility table stored in the peripheral facility table unit 1350 (step S14). In addition, the target facility extraction unit 1400 has a monitoring target table (FIG. 10) in which the monitoring target facility management database 1100 (see FIG. 4) stores the data collection interval and data collection instruction associated with the acquired facility ID. (See step S15).

  The target equipment extraction unit 1400 indicates that the data collection instruction of the equipment ID acquired from the peripheral equipment table of the peripheral equipment table unit 1350 among “instructed”, “target”, or “non-target” that the data collection instruction can take is “target ] Is determined (step S16). When the data collection instruction associated with the acquired facility ID is “target” (step S16—Yes), the target facility extraction unit 1400 associates the acquired facility ID with the data collection interval and stores them in the buffer. (Step S17).

  The target facility extraction unit 1400 determines whether there is a facility ID that has not been acquired in the peripheral facility table unit 1350 (step S18). When there is no equipment ID that has not been acquired in the peripheral equipment table unit 1350 (step S18—No), the target equipment extraction unit 1400 arranges the data collection intervals stored in the buffer in order of increasing interval (step S19).

  The target facility extraction unit 1400 acquires the facility ID from the buffer. In addition, the target facility extraction unit 1400 acquires the group ID associated with the facility ID from the facility group table (see FIG. 11) stored in the monitoring target facility management database 1100 (step S20). The target facility extraction unit 1400 stores the acquired group ID in the target facility table unit 1450 as data of the target facility table (see FIG. 17). Here, if the group IDs overlap, that is, if the group ID is already stored in the target equipment table, the target equipment extraction unit 1400 does not newly store the group ID (step S21).

  The target facility extraction unit 1400 determines whether or not the buffer is empty. In addition, the target facility extraction unit 1400 determines whether or not the number of path changeable numbers has been processed, for example, whether or not the number of acquired group IDs is greater than or equal to the number of path changeable numbers (step S22). When the buffer is empty or when processing is performed up to the path changeable number (step S22—Yes), the target facility extraction unit 1400 calls the change path calculation unit 1500 (see FIG. 4) (step S23).

  On the other hand, if the data collection instruction for the acquired equipment ID is not “target” in step S16 (step S16—No), the processing of the target equipment extraction unit 1400 proceeds to step S18. In Step S18, when there is no equipment ID that has not been acquired in the peripheral equipment table 1350 (Step S18-Yes), the target equipment extraction unit 1400 returns the processing of the target equipment extraction unit 1400 to Step S14. In step S22, when the buffer is not empty and the number of routes that can be changed is not processed, the processing of the target facility extraction unit 1400 returns to step S20.

  FIG. 28 is a flowchart illustrating an operation procedure of the change route calculation unit when calculating the change route. The change route calculation unit 1500 acquires a predetermined number (number of route changeable) group IDs in descending order of priority from the target facility table (see FIG. 17) stored in the target facility table unit 1450. (Step S24). In the changed route calculation unit 1500, the monitoring target facility management database 1100 stores the start point (latitude, longitude) and end point (latitude, longitude) of the route in the section where the facility group indicated by the group ID and the route face each other. Is obtained from the group position table (see FIG. 12) (step S25).

  The changed route calculation unit 1500 determines the start point position and the end point position of the route of the section facing each group (in FIG. 2, the facility groups 700-a, 700-b, 700-c) and the passing points. By inputting the position into the route search device 200 (see FIG. 4), the route search device 200 is made to calculate another passing point position and the expected time Tn as the changed route (step S26). Further, the changed route calculation unit 1500 stores the group ID, the passing point position, and the estimated time Tn in the changed route table unit 1550 (see FIG. 4) (step S27). Also, the changed route calculation unit 1500 calls the route determination unit 1600 (see FIG. 4) (step S28).

  FIG. 29 is a flowchart illustrating an operation procedure of the route determination unit when determining a route. The route determination unit 1600 acquires the expected time Tn from the basic data of the changed route table (see FIG. 19) stored in the changed route table unit 1550 (step S29). Further, the route determination unit 1600 determines whether or not the acquired predicted time Tn is equal to or less than a threshold value (step S30). When the acquired predicted time Tn is less than or equal to the threshold value (step S30—Yes), the route determination unit 1600 stores the group ID, the passing point position, and the predicted time Tn in the changed route table (FIG. 19 and FIG. 20).

  The route determination unit 1600 stores the acquired group ID, passing point position, and estimated time Tn in the final route table unit 1650 (see FIG. 4) as data of the final route table (see FIGS. 13 and 14). (Step S31). In this way, the route determination unit 1600 designates a facility group or facility for which data and the like are to be collected.

  The route determination unit 1600 acquires the facility ID associated with the acquired group ID from the facility group table (see FIG. 11) stored in the monitoring target facility management database 1100 (step S32). In addition, the route determination unit 1600 changes the data collection instruction associated with the acquired equipment ID to “instructed” in the monitoring target table (see FIG. 10) stored in the monitoring target equipment management database 1100 (step S33). ).

  FIG. 30 is a flowchart illustrating an operation procedure of the output device when calculating the final route. The output device acquires the passing point position and the estimated time Tn from the final route table (see FIGS. 13 and 14) stored in the final route table unit 1650 (step S34). The output device 900 sends information (departure location, destination location, and passage location) indicating the final route to the route guidance device 540 mounted on the operating business vehicle 500 via a storage medium or a communication line. Transmit (step S35).

  Next, an operation procedure of the passing point designation device when the business vehicle equipped with the data collection device returns to the office and the facility maintenance data stored in the facility maintenance database of the facility maintenance device is updated will be described.

  FIG. 31 is a flowchart showing the operation procedure of the passing point designating device when notified from the equipment maintenance device that the equipment maintenance data table has been updated. The facility maintenance apparatus 400 acquires the facility maintenance data collected by the data collection device 530 from the data collection device 530 mounted on the business vehicle 500, and stores the acquired facility maintenance data in the facility maintenance data table ( (See FIG. 7) (step Sc1).

  Further, the facility maintenance apparatus 400 registers the facility ID, the previous data collection date, and the record number in the record number table (see FIG. 6) stored in the facility maintenance database 410. In addition, the facility maintenance device 400 notifies the passing point designation device 1000 that the facility maintenance data has been updated. The passing point designation device 1000 calls the monitoring target equipment update unit 1700 (step Sc2).

  The monitoring target equipment update unit 1700 refers to the equipment maintenance data table (see FIG. 7) stored in the equipment maintenance database 410, and among the equipment maintenance data whose last data collection date is today (collected this time) It is determined whether there is any unacquired maintenance data (step Sc3).

  When there is no acquisition in the equipment maintenance data (step Sc3-Yes), the monitoring target equipment update unit 1700 refers to the record number table (see FIG. 6) stored in the equipment maintenance database 410, and the equipment maintenance that has not been acquired. The equipment ID associated with the record number for which data should have been registered is acquired. And the monitoring object equipment update part 1700 refers to the management data table (refer FIG. 5) which the equipment maintenance database 410 memorize | stores, and the data collection state matched with acquired equipment ID is "Without acquisition." Register (step Sc4).

  Moreover, the monitoring object equipment update part 1700 determines an equipment status for every equipment based on the equipment maintenance data whose last data collection date is today (collected this time) (step Sc5).

  In addition, the monitoring target equipment update unit 1700 determines whether or not the determined equipment status includes at least one of abnormality and priority monitoring 1 to 3 (step Sc6). When the determined equipment status includes at least one of abnormality and priority monitoring 1 to 3 (step Sc6-Yes), the monitoring target equipment update unit 1700 stores the management data table stored in the equipment maintenance database 410 The determined equipment status is registered in the equipment status of the equipment in (Step Sc7).

  On the other hand, in step Sc6, when neither the abnormality nor the priority monitoring 1 to 3 is included in the determined equipment status (step Sc6-No), the equipment maintenance database 410 stores the monitoring target equipment update unit 1700. “Normal” is registered in the equipment status of the equipment in the management data table (step Sc8). In Step Sc3, when there is no unacquired equipment maintenance data (Step Sc3-No), the monitoring target equipment update unit 1700 advances the process to Step Sc5.

  FIG. 32 is a flowchart showing the operation procedure of the passing point designation device when notified from the equipment maintenance device that the equipment maintenance data table has been updated. The equipment maintenance apparatus 400 notifies the passing point designating apparatus 1000 that the equipment maintenance data stored in the equipment maintenance database 410 has been updated (step Sa1). The passing point designation device 1000 calls the monitoring target equipment update unit 1700 (step Sa2).

  FIG. 33 is a flowchart showing the operation procedure of the monitoring target equipment updating unit when updating the equipment to be monitored. The monitoring target equipment updating unit 1700 acquires the equipment ID whose last data collection date is today from the management data table (see FIG. 5) stored in the equipment maintenance database 410 (step Sa3).

  The monitoring target equipment update unit 1700 determines whether or not the equipment ID whose last data collection date is today has been acquired (step Sa4).

Obtained from the data table (step Sa5).

  Also, the monitoring target equipment update unit 1700 refers to the management data table (see FIG. 5) stored in the equipment maintenance database 410, and determines whether or not the acquired equipment status is “normal” (step Sa6). . When the acquired equipment status is not “normal” (step Sa6-No), the monitoring target equipment updating unit 1700 determines which of the priority monitoring 1 to 3 is the acquired equipment status (step Sa7).

  In step Sa7, when the acquired equipment status is priority monitoring 1, the monitoring target equipment update unit 1700 stores the monitoring target table (see FIG. 10) stored in the monitoring target equipment management database 1100 (see FIG. 4). The data collection interval associated with the acquired equipment ID is registered as a value (number of days) “90” (step Sa8).

The data collection interval is registered as a value (number of days) “30” (step Sa10).

  Then, the monitoring target facility updating unit 1700 changes the data collection instruction of the monitoring target table (see FIG. 10) stored in the monitoring target facility management database 1100 to “not applicable” (step Sa11). The monitoring target facility update unit 1700 updates each data item in the monitoring target table stored in the monitoring target facility management database 1100 (step Sa12), and returns the process to step Sa3.

  On the other hand, when the acquired equipment status is “normal” in step Sa6 (step Sa6-Yes), the monitoring target equipment updating unit 1700 determines whether or not the acquired data collection state is “not acquired”. (Step Sa13). When the acquired data collection state is not “not acquired” (step Sa13-No), the monitoring target facility update unit 1700 stores data in the monitoring target table (see FIG. 10) stored in the monitoring target facility management database 1100. The collection instruction is changed to “not applicable” (step Sa14). Also, the monitoring target facility update unit 1700 registers the value (number of days) “0” as the data collection interval of the monitoring target table stored in the monitoring target facility management database 1100 (step Sa15).

  In step Sa13, when the acquired data collection state is “not acquired” (step Sa13—Yes), the monitoring target equipment update unit 1700 advances the process to step Sa11. Moreover, in step Sa4, when the equipment ID whose last data collection date is today cannot be acquired (step Sa4-No), each part of the passing point designating apparatus 1000 ends the processing.

Next, an operation procedure of the passing point specifying device when the data collection interval is updated at a predetermined time will be described.
