It is a general term for a 9m aerial work vehicle, a 6m aerial work vehicle, or something that has power, such as an elevator. Hereinafter, the region where the object can exist is referred to as a “target region”. For example, in each embodiment, a case will be described in which the target area is each floor of a building construction site. “Specify the operating status” means that the equipment is in operation (hereinafter referred to as “operating status”) or that the equipment is not operating (hereinafter referred to as “non-operating status”). It is not limited to specifying whether there is any, but includes specifying the operating rate of materials and equipment (the ratio of operating status within a predetermined period (for example, one day or one week)).

  Here, a plurality of workers are performing construction work in the target area, and those who are involved in the management of the site among the plurality of workers are hereinafter referred to as site managers. However, when it is not necessary to distinguish between normal workers and site managers, these are collectively referred to simply as “workers”. There are a plurality of workers, each of which has a receiving terminal. Each of these receiving terminals is a terminal that receives radio waves from equipment beacons and fixed beacons. Drawings of the construction site are displayed on the display of this receiving terminal, and equipment icons indicating the positions of the objects (materials and equipment) and worker icons indicating the positions of the workers are displayed on the drawings.

Further, the current position of the worker may be highlighted by inputting the name and searching.

(Configuration-Key beacon)
The key beacon 60 is a key transmitter arranged in the vicinity of the key for operating the equipment. Specifically, the key beacon 60 attaches a key beacon ID to the radio wave to uniquely identify itself, Transmits radio waves in all 360 ° directions. Here, “disposed near the key” means that the beacon 60 is disposed with respect to the key at such a short distance that there is no problem even if the position of the key beacon 60 is identified with the position of the key. For example, a state in which the key beacon 60 is attached to the key via a fitting such as a metal fitting or a string, or a state in which the key beacon 60 is housed in a common key bag together with the key. Including. One key beacon 30 is arranged near each key by an operator.

(processing)
Next, processing executed by the equipment / equipment operating status identification system according to the first embodiment will be described. In this equipment / equipment operating status specifying system, beacon registration processing, server DB update processing, application display log update processing, operating status specifying processing, and operating rate calculation processing are generally executed.

(Processing-Beacon registration processing)
First, a beacon registration process executed by the control unit 17 of the receiving terminal 10 according to the first embodiment will be described. This beacon registration processing is roughly performed by a worker who goes around the construction site while holding the receiving terminal 10, places the fixed beacon 20 on the construction site, and receives information about the arranged fixed beacon 20 on the receiving terminal 10. This process is executed when the touch pad 11 is registered in the drawing DB 18b or the transmission position DB 52a.

  Specifically, the worker first places the fixed beacon 20 on the construction site. Next, the worker registers the beacon ID and the transmission position information of the fixed beacon 20 arranged by himself / herself in the transmission position DB 52a of FIG. A specific method of this registration is arbitrary, and an example thereof will be described below.

  First, the control unit 17 displays a beacon registration icon on the display 12 and enters a beacon registration mode when the icon is pressed by an operator. In this mode, first, the setting of the drawing to be registered is accepted. Specifically, the control unit 17 displays a thumbnail of the drawing information stored corresponding to the item “drawing information” in the drawing DB 18b, and one of these thumbnails is selected by the worker (by tapping or the like). Then, the drawing information is displayed on the display 12. Further, a beacon icon indicating the position of the fixed beacon 20 is displayed at the center of the screen. And the control part 17 receives the movement of the display position of the said beacon icon. Specifically, for example, when pressing of an arrow-shaped beacon movement icon (not shown) displayed on the display 12 is received, the beacon icon may be received in the direction indicated by the arrow, or the beacon icon In a state where the display position is pressed by the operator's finger, when a finger slide is received, the beacon icon may be moved along the slide. And when a definite icon (illustration omitted) is pressed in the state which moved the beacon icon to the position which installed the fixed beacon 20, the window which receives input of beacon ID is displayed. And a user inputs beacon ID, confirming beacon ID described in fixed beacon 20, and when beacon ID is inputted, it specified with a publicly known method based on the position of the beacon ID and a beacon icon. The transmission position information is transmitted in association with the server 50 and stored in the transmission position DB 52a. Further, the beacon ID input as described above is stored in the information corresponding to the item “beacon ID” of the drawing to be registered in the drawing DB 18b of FIG. This completes the beacon registration process.

(Processing-Server DB update processing)
Subsequently, a server DB update process executed by the control unit 51 of the server 50 according to the first embodiment will be described. This server DB update process is a process for updating the server DB 52b to the latest one based on a signal transmitted from the receiving terminal 10 (hereinafter referred to as a log signal). In addition, the timing which performs this server DB update process is arbitrary, for example, may be performed when the power supply of the server 50 is turned on.

  First, when receiving a radio wave from the fixed beacon 20, the receiving terminal 10 specifies a fixed beacon ID (fixed beacon ID transmitted from the fixed beacon 20) attached to the received radio wave. At this time, when radio waves are received from a plurality of fixed beacons 20, the radio wave strengths of these are compared, and the fixed beacon 20 having the strongest radio wave intensity (that is, the closest to the receiving terminal 10 exists). A fixed beacon ID of the fixed beacon 20) is specified. Next, the floor corresponding to the fixed beacon ID specified in this way is specified from the drawing DB 18b shown in FIG.

  Similarly, when receiving the radio wave from the equipment / beacon 30, the receiving terminal 10 specifies the equipment / beacon ID attached to the received radio wave (the equipment / beacon ID transmitted from the equipment / beacon 30). Then, the radio field intensity from the equipment beacon 30 is specified by a known method. When radio waves from the equipment / beacon 30 are not received (that is, when the position of the receiving terminal 10 is not within a predetermined distance from the equipment / beacon 30), the equipment / beacon ID and radio wave intensity are not specified. Good.

  Similarly, when receiving the radio wave from the key beacon 60, the receiving terminal 10 specifies the key beacon ID (the key beacon ID transmitted from the key beacon 60) attached to the received radio wave. When the radio wave from the key beacon 60 is not received (that is, when the position of the receiving terminal 10 is not within a predetermined distance from the key beacon 60), the key beacon ID need not be specified.

  In addition to the time stamp of the transmission time and the terminal ID of the receiving terminal 10 itself, the receiving terminal 10 further includes the equipment / beacon ID, the fixed beacon ID, the key beacon ID, the floor, and the radio wave intensity specified as described above. The attached log signal is created and transmitted to the server 50 by a known method. Such transmission processing by the receiving terminal 10 may be executed at an arbitrary timing, and may be executed at a predetermined interval (for example, every 5 seconds), for example. Then, the log signal is transmitted from the plurality of receiving terminals 10 to the server DB 52b by performing the transmission process in the same manner by the plurality of receiving terminals 10.

  The control unit 51 of the server 50 sequentially updates the server DB 52b every time it receives a log signal from the receiving terminal 10 described above. Specifically, the information corresponding to the item “time” is updated based on the time stamp included in the received log signal, and the information corresponding to the item “terminal ID” is updated based on the terminal ID included in the log signal. The information corresponding to the item “equipment beacon ID” is updated based on the equipment beacon ID included in the log signal, and the information corresponding to the item “fixed beacon ID” based on the fixed beacon ID included in the log signal. Update the information corresponding to the item “key beacon ID” based on the key beacon ID included in the log signal, update the information corresponding to the item “floor” based on the floor included in the log signal, With reference to the transmission position DB 52a, transmission position information corresponding to the fixed beacon ID included in the log signal is specified, and the item “transmission position information” is based on the specified transmission position information. Update the response to information, to update the information corresponding to the item "Accuracy" on the basis of the radio wave reception intensity that is included in the log signal. As a method for obtaining accuracy, for example, the accuracy may be specified with reference to an accuracy specification table (not shown) that stores radio wave reception intensity and accuracy in association with each other, but is not limited thereto. Further, in the first embodiment, the accuracy is specified and stored on the server 50 side as described above. However, the present invention is not limited to this, and the accuracy is determined by the receiving terminal 10 and then transmitted in the log signal. The accuracy included in the signal may be stored. Alternatively, the transmission position DB 52a may be provided in the reception terminal 10, and the transmission position information may be specified on the reception terminal 10 side before being transmitted with the log signal. This completes the server DB update process.

  Thus, the control unit 51 of the server 50 is the receiving terminal 10 that moves with the worker by updating the information corresponding to the item “transmission position information” based on the log signal from the receiving terminal 10, It functions as terminal position specifying means for specifying the position of the receiving terminal 10 that receives radio waves from the equipment beacon 30 attached to the equipment. Further, by updating the information corresponding to the item “accuracy” based on the log signal, the receiving terminal 10 and the equipment beacon 30 can interact with each other based on the radio wave reception intensity from the equipment beacon 30 of the receiving terminal 10. It functions as an estimated distance specifying means for specifying the estimated distance between. Further, by updating the server DB 52b by associating the information of the item “transmission position information” and the item “accuracy”, the position of the receiving terminal 10 specified by the terminal position specifying means and the estimated distance specification at the position It functions as a log acquisition unit that acquires a log in which the estimated distance specified by the unit is associated with each other.

(Processing-Application display log update processing)
Subsequently, an application display log update process executed by the control unit 51 of the server 50 according to the first embodiment will be described. In the following description of processing, step is abbreviated as “S”. FIG. 12 is a flowchart of the application display log update process according to the first embodiment, and FIG. 13 is a flowchart of the application display log update process following FIG. This application display log update process is a process for updating the application display log based on the log signal received from the receiving terminal 10 and improving the accuracy of the display position of the equipment icon. Note that the application display log update process may be executed at any timing, and may be executed when the server 50 is powered on, for example.

  In SA1, the control unit 51 of the server 50 determines whether or not a log signal related to the position of the equipment is received. The specific method of this determination is arbitrary. For example, when information including the equipment / beacon ID is newly stored with reference to the item “equipment / beacon ID” in the server DB 52b, a log signal regarding the position of the equipment / equipment is displayed. It is determined that it has been acquired. For example, even if a log signal is received from the receiving terminal 10, it is assumed that there is no information regarding the position of the equipment unless the equipment / beacon ID is included in the log signal. And it waits until the log signal regarding the position of materials and equipment is received (SA1, No), and when it receives (SA1, Yes), it shifts to SA2.

  In SA2, the control unit 51 of the server 50 adds a log to the equipment position log table 52c (each item other than the item “continuity”) based on the received log signal. Specifically, a new log ID is added as information corresponding to the item “log ID” of the equipment / equipment position log table 52c, and the item “equipment beacon ID”, item “time”, and item “outgoing” of the added record are added. In the “location information” and item “accuracy”, information corresponding to the item having the same name in the server DB 52b is rearranged and stored in chronological order for each equipment beacon ID.

  In SA3, the control unit 51 of the server 50 determines the elapsed time t1 from the time of the log added in the previous SA2 process (hereinafter referred to as the previous log) to the log added in the current SA2 process (hereinafter referred to as the current log). Is calculated. Specifically, referring to the equipment position log table 52c of FIG. 8, the time from the time stored in the item “time” of the previous log to the time stored in the item “time” of the current log is calculated. This time is calculated as the elapsed time t1. For example, when L08 in FIG. 8 is the current log, the elapsed time from the previous log (L07) is 25 minutes.

  In SA4, the control unit 51 of the server 50 determines whether or not the elapsed time t1 calculated in SA3 is 1 minute or less. Although 1 minute is set in the first embodiment, this time is merely an example, and any time such as 3 minutes or 5 minutes can be applied. If the elapsed time t1 is not 1 minute or less (SA4, No), the process proceeds to SA5. If the elapsed time t1 is 1 minute or less (SA4, Yes), the process proceeds to SA7.

  In SA5, the control unit 51 of the server 50 sets a 0 flag (non-contiguous log) to the current log. Specifically, in the first embodiment, “0” is stored as information corresponding to the item “continuity” of the current log in the equipment position log table 52c shown in FIG. For example, if L08 in FIG. 8 is the current log, the elapsed time t1 from the previous log (L07) is 25 minutes and there is no continuity because 1 minute or more has passed, so the item “continuity” “0” is stored in.

  In SA6, the control unit 51 of the server 50 generates a new time pack log. For example, in the above example, a time pack log having the transmission position coordinates (X002, Y001) and accuracy (20) of the current log (L08) is added to the lower end of the time pack log table 52d in FIG. When a new time pack log is created in this way (hereinafter “current time pack log”), the current time pack log and the previously generated time pack log (hereinafter “previous time pack log”) are subsequently used. The application display log is updated based on the comparison. Details of updating the application display log will be described later.

  In SA7, the control unit 51 of the server 50 sets one flag (continuous log) in the current log. Specifically, in the first embodiment, “1” is stored as information corresponding to the item “continuity” of the current log in the equipment position log table 52c shown in FIG.

  In SA8, the control unit 51 of the server 50 compares the accuracy of the current log with other logs up to a log having a 0 flag before the current log. For example, if the current log is L07, the accuracy of the logs up to L05 having a 0 flag before L07 (ie, L05, L06) is compared with the accuracy of the current log (L07).

  In SA9, the control unit 51 of the server 50 determines whether or not the accuracy of the current log is equal to or less than the accuracy of all other compared logs. For example, in the above example, the accuracy (40) of L07 is not less than or equal to the accuracy (30) of L06, so it is determined that the accuracy of the current log is not less than or equal to the accuracy of all the compared logs. If the accuracy of the current log is less than or equal to the accuracy of all the compared logs (SA9, Yes), the current log is a log acquired closer to the equipment than the existing log. It is assumed that the current log is more suitable for representing the position of the equipment, and the process proceeds to SA10 to overwrite the time pack log with the current log. On the other hand, if the accuracy of the current log is not less than or equal to the accuracy of all the compared logs (SA9, No), the existing log is a log acquired closer to the equipment than the current log, It is assumed that the existing log is more suitable for indicating the position of the equipment, and the application display log update process is terminated without overwriting the time pack log.

  In SA10, the control unit 51 of the server 50 overwrites the transmission position coordinates of the time pack log. Specifically, the latest time pack log (current time pack log) shown in FIG. 2 is overwritten with the transmission position coordinates and accuracy of the current log. As described above, the control unit 51 of the server 50 overwrites the current time pack log with a log with a low accuracy among a plurality of logs, thereby allowing the log acquisition means to be within a predetermined time range (in the first embodiment, As described above in SA4, it functions as a log specifying unit that specifies a time pack log that is a log indicating the smallest estimated distance from a plurality of logs acquired in one minute).

  In SA11, the control unit 51 of the server 50 calculates an elapsed time t2 from the previous time pack log to the current time pack log. For example, referring to the item “time” in the equipment / equipment position log table 52c of FIG. 8, in the example of FIG. 8, the elapsed time t2 from the previous time pack log (L02) to the current time pack log (L06) is 5 minutes. I understand that there is.

  In SA12, the control unit 51 of the server 50 determines whether or not the elapsed time t2 calculated in SA11 is equal to or longer than a predetermined time (one day in the present embodiment). If the elapsed time t2 is 1 day or longer (SA12, Yes), the information of the previous time pack log is old and has low usefulness, so the process proceeds to SA 15 to overwrite it with the current time pack log. On the other hand, if the elapsed time t2 is not longer than one day (SA12, No), the information of the previous time pack log is not old, and the most useful one is selected from the current time pack log and the previous time pack log. To SA13. In the first embodiment, one day is used as a reference for determining whether or not the time pack log information is old. However, the present invention is not limited to this, and an arbitrary period can be set. For example, 6 hours or 12 hours may be used. . In the example of FIG. 8, it is determined that the elapsed time t2 from the previous time pack log (L02) to the current time pack log (L06) is 5 minutes and has not yet exceeded one day.

  In SA13, the control unit 51 of the server 50 compares the accuracy of the current time pack log with the accuracy of the previous time pack log. For example, the comparison is made with reference to the item “Accuracy” in the time pack log table 52d shown in FIG.

  In SA14, the control unit 51 of the server 50 determines whether or not the accuracy of the current time pack log is equal to or less than the accuracy of the previous time pack log. For example, in the example of FIG. 8, the accuracy of the current time pack log is 30, and the accuracy of the previous time pack log is 10. Therefore, it is determined that the accuracy is not less than the accuracy of the previous time pack log. If the accuracy of the current time pack log is less than or equal to the accuracy of the previous time pack log (SA14, Yes), the current time pack log is acquired closer to the equipment beacon 30 than the previous time pack log. It is assumed that the log is suitable for indicating the position of the equipment, and the process proceeds to SA 15 to update the application display log to the current time pack log. On the other hand, when the accuracy of the current time pack log is not less than or equal to the accuracy of the previous time pack log (SA14, No), the previous time pack log was acquired in a state closer to the equipment beacon 30 than the current time pack log. The log is suitable for representing the position of the equipment, and the application display log is not updated and the application display log process is terminated without changing the previous time pack log. In this way, the control unit 51 of the server 50 identifies the application display log by comparing the time pack logs, and thereby identifies the position of the object based on the time pack log identified by the log identifying means. It functions as a specifying means.

  In SA15, the control unit 51 of the server 50 overwrites the application display log with the current time pack log. In other words, when the elapsed time t2 is 1 day or more (SA12, Yes), the information in the previous time pack log is old and has low usefulness, so the application display log is overwritten with the current time pack log in order to overwrite it with the latest log. To do. Also, if the accuracy of the current time pack log is less than or equal to the accuracy of the previous time pack log (SA14, Yes), the current time pack log is acquired closer to the equipment beacon 30 than the previous time pack log. This log is suitable for representing the position of equipment, and the application display log is overwritten with the current time pack log. Above, description of an application display log update process is complete | finished.

(Processing-Operation status identification processing)
Next, the operation status specifying process executed by the control unit 51 of the server 50 according to the first embodiment will be described. This operation status specifying process is a process for specifying whether or not the equipment is operating (operation status) based on information from the equipment beacon 30 and the key beacon 60. In addition, the timing which performs this operation condition specific process is arbitrary, for example, may be performed when the power supply of the server 50 is turned on. FIG. 14 is a flowchart of the operation status specifying process.

  In SB1, the control unit 51 of the server 50 determines whether or not a log signal related to the key position has been received. The specific method of this determination is arbitrary. For example, referring to the item “key beacon ID” of the server DB 52b, when information including the key beacon ID is newly stored, the log signal regarding the key position is acquired. judge. And it waits until a log signal is received (SB1, No), and when a log signal is received (SB1, Yes), the process proceeds to SB2.

  In SB2, the control unit 51 of the server 50 adds a log to the key position log table 52e based on the received log signal. Specifically, a new key log ID is added as information corresponding to the item “key log ID” of the key position log table 52e, and the item “equipment beacon ID”, item “time”, item “ Information corresponding to the item having the same name in the server DB 52b is rearranged and stored in order of time series for each equipment beacon ID. In addition, the item “approach determination flag” refers to the item “transmission position coordinates” in the server DB 52b, extracts the position of the equipment at the peripheral time (for example, three minutes before and after the current time), and the key position and If the position of the material / equipment is within a predetermined distance, it is determined that it is approaching, and “1” is stored. If it is not within the predetermined distance, it is determined that it is not approaching and “0” is stored. Here, a specific method for determining whether or not the key and the equipment / equipment are within the predetermined distance is arbitrary. For example, whether the key beacon 60 and the equipment / beacon 30 are in the vicinity of the fixed beacon 20 adjacent to each other. Alternatively, when they exist in the vicinity of the same fixed beacon 20, they may be determined to be close to each other. However, the present invention is not limited to this method. For example, the position of the key beacon 60 or the equipment beacon 30 is specified based on the radio wave intensity from each beacon, the distance between these positions is calculated, and the calculated distance May be determined within a predetermined distance (for example, 5 m).

  In SB3, the control unit 51 of the server 50 updates the key time pack log table 52f. Specifically, all key logs within a predetermined time (10 minutes in the present embodiment) including the added key log are referred to, and at least one key log with an approach determination flag = 1 exists. When “1” is stored in the item “pack approach determination flag” of the key time pack log table 52f and there is no key log with the approach determination flag = 1, the item “pack approach” of the key time pack log table 52f is stored. “0” is stored in the “determination flag”.

  In SB4, the control unit 51 of the server 50 identifies the operating status of the equipment. Specifically, among the information stored in the key time pack log table 52f updated in SB3, with reference to the latest key time pack log (the log of determination ID 001 in FIG. 9), the item “pack approach determination” If “1” is stored in the flag, it is determined as “operating”, and if “0” is stored, it is determined as “non-operating”. As described above, in the present embodiment, the operation status is determined by referring to the key time pack log in which a plurality of key logs are combined into one. Therefore, the position coordinates are erroneously detected for some reason such as communication failure. A misjudgment caused by judging the operating status based on one key log can be eliminated. The operation status specifying process is thus completed.

(Processing-Occupancy rate calculation processing)
Next, the operation rate calculation process executed by the control unit 51 of the server 50 according to the first embodiment will be described. This operation rate calculation process is a process for calculating the operation rate of a plurality of materials and equipment to grasp unused materials and equipment and reduce the rental cost of the materials and equipment. In addition, the timing which performs this operation rate calculation process is arbitrary, for example, may be performed by the control part 51 of the server 50 at a predetermined timing once a day or once every half day.

First, the control unit 51 of the server 50 refers to the key time pack log table 52f, and for each key beacon ID, the number of logs in which the equipment is operating (that is, “1” is set in the item “key time pack log”). The number of logs stored) and the number of logs in which the equipment is not in operation (that is, the number of logs having “0” stored in the item “key time pack log”) are calculated. Next, the operation rate of the equipment is calculated based on the following formula (1).
R = n _on / (n _on + n _off ) (1)
here,
R = utilization rate of materials and equipment,
n _on = number of logs that the equipment is in operation,
n _off = number of logs when the equipment is not in operation.
For example, in the example of FIG. 9, n _on = 2, n _off = 1, and R = 2/3 (ie, approximately 66.7%). Use the same procedure to calculate the availability of all materials and equipment.

  Next, the calculated availability of the equipment is arranged in descending order, and the availability table 52g shown in FIG. 10 is updated. At this time, as information corresponding to the item “rank”, numbers representing rank (1 to 5 in the present embodiment) are stored in advance. Based on the equipment / beacon ID of the equipment / material, the equipment / material DB 18c may be referred to and acquired. For the item “operating rate”, the operating rate of the specified equipment is stored as described above. Thus, the information stored in the operating rate table 52g is transmitted to the receiving terminal and displayed on the display of the receiving terminal, so that the worker can grasp the operating status at a glance. In addition, since the position and availability of materials and equipment can be visualized at the same time, for example, materials and equipment with low availability can be easily found and returned from a wide construction site, improving convenience for workers and reducing construction costs. Can be reduced.

(Effect of Embodiment 1)
As described above, according to the equipment / equipment operating status specifying system of the first embodiment, the operating status of the equipment / equipment is specified based on the information transmitted from the equipment / beacon 30, so the position of the equipment / equipment is specified. Therefore, it is possible to easily identify the operation status of the equipment using the equipment beacon 30 for preventing the construction cost from being increased based on the use of an unnecessary number of equipment.

  In addition, since the operating status of the equipment is specified based on the radio waves from the key transmitter and the equipment beacon 30, the operating status of the equipment is determined based on the fact that the key of the equipment is located in the vicinity of the equipment. Can be easily identified, and convenience is improved.

  In addition, since the operation rate of materials and equipment is calculated as the operation status of materials and equipment, the operation status of materials and equipment can be easily grasped as numerical values, and the operation status of multiple materials and equipment can be easily compared, improving convenience. .

Moreover, the operating rate of the equipment, because the calculation by the equation _{R = n on / (n on} + n off), based on the equipment of the log can easily identify the operation status of the equipment, thereby improving convenience .

  In addition, if at least one key log specifying that the equipment is in operation is included in the plurality of key logs, the equipment is assumed to be in operation. Even if there is an omission of acquisition of a key log indicating that the key log is in an operational state, it can be determined that it is supplemented with another key log, and the specific accuracy is improved.

(Embodiment 2)
Next, the equipment / equipment operating status specifying system according to Embodiment 2 of the present invention will be described. Here, in the first embodiment, the operating status of the equipment is specified based on whether or not the key beacon 60 and the equipment beacon 30 are located in the vicinity. However, in the second embodiment, the detection of the magnetic sensor is performed. Based on the results, identify the operation status of materials and equipment. The configuration of the equipment / equipment operating status specifying system according to the second embodiment is substantially the same as the configuration of the first embodiment except for the case of special mention, and the configuration that is substantially the same as the configuration of the first embodiment. The same reference numerals as those used in the first embodiment are given as necessary, and the description thereof is omitted.

(Constitution)
First, the configuration of the second embodiment will be described. 15A and 15B are diagrams showing materials and equipment according to Embodiment 2, in which FIG. 15A shows materials and equipment in a non-operating state, and FIG. 15B shows materials and equipment in an operating state.

  As shown in FIG. 15, the equipment according to the second embodiment (in this example, an aerial work vehicle) includes a base 70, a scaffold 71, a magnet 72, and a magnetic sensor 73. Here, the magnet 72 and the magnetic sensor 73 together with the receiving terminal 10, the fixed beacon 20, the equipment beacon 30, and the key beacon 60 acquire operational status information for specifying the operational status of the equipment in the target space. The acquisition means is configured.

  The base 70 is a portion provided with wheels and the like located at the lower end of the equipment. The scaffold 71 is a part on which an operator gets on and works, and as shown in FIG. 15 (b), is separated from the base 70 when the equipment is in operation, as shown in FIG. 15 (a). As shown, the equipment is close to the base 70 when the equipment is not in operation. The magnet 72 is a known magnet installed on the scaffold 71. The magnetic sensor 73 is a magnetic detection unit that detects whether the magnet 72 is approaching. When the magnet 72 is not approaching (that is, when the equipment is in operation), the magnetic sensor 73 transmits a detection signal including information on the operation flag on to the equipment beacon 30, and the magnet 72 Such detection signals are not transmitted when approaching (that is, when the equipment is not in operation). In the second embodiment, the magnetic sensor 73 is installed on the base 70, and the magnet 72 is installed on the scaffold 71. However, these may be arranged opposite to each other.

(processing)
Next, processing executed in the second embodiment will be described. In the second embodiment, the magnetic sensor 73 always detects whether or not the magnet 72 is approaching, and when the magnet 72 is not approaching (that is, when the equipment is in operation), as described above. A detection signal is transmitted to the equipment beacon 30. As long as the equipment beacon 30 receives this detection signal, the equipment beacon 30 transmits the radio wave including the operation flag on information in addition to its own equipment beacon ID when transmitting the radio wave to the receiving terminal 10. If the operation flag ON information is included, the receiving terminal 10 assumes that the equipment is in operation, stores “1” in the approach determination flag described in Embodiment 1, and sets the operation flag ON. If the information is not included, it is assumed that the equipment is not in operation, and “0” is stored in the approach determination flag described in the first embodiment.

(Effect of Embodiment 2)
As described above, according to the material / equipment operating state specifying system of the second embodiment, either the scaffold 71 or the magnetic sensor 73 is provided with the magnet 72 and the other is provided with the magnetic sensor 73. Since the operating status of the equipment is specified based on the above, the operating status of the equipment can be easily specified based on the positional relationship between the magnet 72 and the magnetic sensor 73, and convenience is improved.

(Embodiment 3)
Next, the material / equipment operating status specifying system according to Embodiment 3 of the present invention will be described. Here, in the second embodiment, the operation status of the equipment is specified based on the detection result of the magnetic sensor 73, but in the third embodiment, the operation status of the equipment is specified based on the detection result of the atmospheric pressure sensor. To do. Note that the configuration of the equipment / equipment operating status specifying system according to the third embodiment is substantially the same as the configuration of the second embodiment unless otherwise specified, and the configuration that is substantially the same as the configuration of the second embodiment. The same reference numerals as those used in the second embodiment are attached as necessary, and the description thereof is omitted.

(Constitution)
First, the configuration of the third embodiment will be described. Here, the equipment of the third embodiment has an atmospheric pressure sensor (not shown) instead of the magnet 72 and the magnetic sensor 73 of the equipment of the second embodiment. This barometric pressure sensor is a barometric pressure measuring means for measuring the barometric pressure at the installation position, and is provided on the scaffold 71 of the equipment. Here, the atmospheric pressure sensor constitutes acquisition means for acquiring operating status information for specifying the operating status of the equipment in the target space, together with the receiving terminal 10, the fixed beacon 20, the equipment beacon 30, and the key beacon 60. To do. Then, the equipment 71 scaffold 71 transmits a detection signal to the equipment beacon 30 using the fact that the altitude changes between operating and non-operating (that is, the atmospheric pressure changes). Specifically, the atmospheric pressure at the time of non-operation is recorded in advance, and when the atmospheric pressure is different from the recorded atmospheric pressure, it is determined that the scaffold 71 is raised and is in an operating state, and a detection signal is Send. However, the method is not limited to this method. For example, when the atmospheric pressure is measured periodically at predetermined time intervals and the atmospheric pressure decreases by a predetermined value or more compared to the past measurement value, the scaffold 71 is raised and is operating. It may be determined that the state is present, and a detection signal may be transmitted. Since processing performed by the equipment beacon 30 and the receiving terminal 10 after transmitting the detection signal is the same as that of the second embodiment, detailed description thereof is omitted.

(Effect of Embodiment 3)
In this way, according to the equipment / equipment operating status specifying system according to Embodiment 3, the operating status of the equipment / equipment is specified based on the measurement result of the barometric sensor installed on the equipment / scaffold 71, so that the scaffold 71 The operational status of materials and equipment can be easily identified based on the change in atmospheric pressure due to the upper and lower sides of the door, improving convenience.

(Embodiment 4)

In particular, the material / equipment operating status specifying program according to the first embodiment is substantially installed in the server 110 via an arbitrary recording medium or network, thereby substantially configuring each unit of the server 110. "Equipment status identification program for materials and equipment" refers to the computer based on the status information acquired by the acquisition means for acquiring the operating status information for identifying the status of operation of materials and equipment in the target space. It is a program for functioning as a specific means for specifying the operating status of materials and equipment.

(Configuration-Server-Data recording part)
The data recording unit 112 is a recording unit that records a program and various data necessary for the operation of the server 110, and can be configured in the same manner as the data recording unit 52 of the first embodiment, for example. The data recording unit 112 generally includes a user DB 112a, an equipment / materials DB 112b, and a drawing DB 112c.

  The user DB 112a is a user information storage unit that stores information about a user who owns the reservation terminal 100. FIG. 17 is a diagram illustrating information stored in the user DB 112a. As shown in FIG. 17, the user DB 112a stores an item “user ID”, an item “name”, an item “company name”, an item “password”, and information corresponding to these items in association with each other. To do.

  Here, as the information corresponding to the item “user ID”, identification information for uniquely identifying each user is stored. For example, “UID0001” and “UID0002”, the alphabet “UID” and a 4-digit number are stored. Identification information consisting of numbers is stored. As information corresponding to the item “name”, the name of the user who owns each reservation terminal 100 is stored. As information corresponding to the item “company name”, the company name to which each user belongs is stored. As information corresponding to the item “password”, a password for performing login authentication of each user is stored.

  Returning to FIG. 16, the equipment / material DB 112 b is equipment / equipment information storage means for storing information on the equipment / materials existing in the target area and information for specifying the reservation status of each equipment / material. FIG. 18 is a diagram illustrating information stored in the material / material DB 112b. As shown in FIG. 18, the equipment DB 112b includes an item “equipment ID”, an item “high vehicle name”, an item “floor”, an item “type”, an item “dedicated”, and an item “reservation”. Information corresponding to each item is stored in association with each other.

  Here, as information corresponding to the item “material / equipment ID”, information for uniquely identifying each material / equipment (aerial work vehicle in the fourth embodiment) is stored, for example, “EID0001”. In addition, identification information including alphabet “EID” and a four-digit number is stored, such as “EID0002”. The item “elevation name” stores information for identifying the name of each equipment. For example, “9m1” indicating the first unit of the 9m aerial work vehicle, and the first unit of the 6m aerial work vehicle. “6m1 No.” shown is stored. As information corresponding to the item “floor”, information for specifying the number of floors of each equipment is stored. For example, “first floor”, “second floor”, and the like are stored. The item “type” stores information for identifying the type of each equipment, for example, “9 m aerial work vehicle” indicating a 9 m aerial work vehicle, “6 m high place indicating a 6 m aerial work vehicle.

  Returning to FIG. 16, the drawing DB 112 c is drawing information storage means for storing drawing information relating to a building. For example, from the information stored in the drawing DB 18 b of FIG. 4, the item “fixed beacon ID” and information corresponding to this item Stores information with and omitted.

(processing)
Next, processing executed by the equipment / equipment operating status identification system according to the fourth embodiment will be described. Prior to this processing, the above-described information is acquired and stored in advance in the user DB 112a, the equipment DB 112b, and the drawing DB 112c. This process includes a reservation process for reserving materials and equipment, and an operation rate specifying process for specifying the operation rate of materials and equipment.

(Processing-Reservation processing)
First, a reservation process for making a reservation for materials and equipment will be described. When the user makes a login request by inputting his / her user ID and password via the touchpad 101 of the reservation terminal 100 by any method, the control unit 104 of the reservation terminal 100 uses the user ID and password as a server. 110. The control unit 111 of the server 110 determines whether or not the combination of the user ID and the password is stored in the user DB 112a. If the combination is stored, the control unit 111 permits login, generates reservation screen information, and generates a reservation terminal. To 100. The control unit 104 of the reservation terminal 100 displays a reservation screen on the display 102 based on the reservation screen information.

  FIG. 19 is a diagram illustrating a display example of a reservation screen. As shown in FIG. 19, the reservation screen includes an item “reservation list”. This item “reservation list” is composed of an item “floor” and an item “high vehicle name”, and is acquired from the equipment DB 112b as information corresponding to the item “floor” and item “high vehicle name”. The information of the same item name is displayed. A free entry column is provided below each high vehicle name, and the user can enter arbitrary information (“Team A” in the example of FIG. 19). In the upper part of the reservation screen, as the information of the logged-in user, the company name (“XX Corporation” in the example of FIG. 19) and the name (“Yoshida” in the example of FIG. 19) acquired from the user DB 112a. ) Is displayed. The reservation screen also includes information for specifying the date (eg, “November 14” in the example of FIG. 19), information for specifying the day of the week (eg, “month” in the example of FIG. 19), and morning and afternoon. Information to be identified (“AM” in the example of FIG. 19) is displayed.

  In addition, “empty”, “done”, and “other” are displayed on the reservation screen as information for specifying the reservation status. The information specifying the reservation status is the equipment that is located on the floor specified by the information corresponding to the item “floor” and is specified by the information corresponding to the item “high vehicle name”. It is the date specified by the information specifying the date, and the information specifying the status of the reservation in the morning or afternoon specified by the information specifying morning and afternoon (hereinafter referred to as these date and morning) Or the combination in the afternoon is referred to as the “reserved time zone”). Of these, “empty” indicates that a reservation has not been made, “done” indicates that a reservation has been made by the logged-in user or another user of the same company as the user, and “other” Indicates that a reservation is made by a user of a company other than the company of the logged-in user. For example, “empty” indicated by reference numeral 120 in FIG. 19 indicates that the equipment of the high vehicle name “9m3” arranged on the floor “2” is reserved for “morning” on the date “November 15”. This indicates that no reservation has been made in the band. Further, for example, “Done” indicated by reference numeral 121 in FIG. 19 indicates that the equipment of the high vehicle name “9m3” arranged in the floor “2” is reserved for “afternoon” on the month “November 15”. This indicates that the reservation is being made by the logged-in user “Yoshida” or another user of the same company “00 Co., Ltd.” as the user “Yoshida” in the time zone. Or, for example, “other” indicated by reference numeral 122 in FIG. 19 indicates that the equipment of the high vehicle name “9m3” arranged on the floor “2” is reserved for “AM” on the date “November 16” This indicates that a reservation is made by a user of a company other than the same company “00 Corporation” as the logged-in user “Yoshida” in the time zone. These pieces of information are specified and displayed by the control unit 111 of the server 110 when the reservation screen is generated based on information corresponding to the item “reservation” in the material / material DB 112b of FIG. 18 and information input by the user at the time of login. The For example, when “20171114am-UID0001” is stored as information corresponding to the item “reservation” and the user ID “UID0001” is acquired as information input by the user at the time of login, the date “November 14” Since it is possible to specify that a reservation is made by a user who has logged in in the “am” reservation time zone of “day”, “done” is displayed at a corresponding portion of the reservation screen. Alternatively, when the user ID included in the information corresponding to the item “reservation” does not match the user ID included in the information input by the user at the time of login, or by referring to the user DB 112a based on each of these user IDs If the specified company name does not match, “other” is displayed in the corresponding part of the reservation screen. Alternatively, “reserved” is displayed in the corresponding part of the reservation screen for a reservation time zone that is not included in the information corresponding to the item “reservation” in the material / equipment DB 112b. However, as a method for specifying such a reservation information storage structure, a reservation time zone, etc., any known structure or method can be employed. As a result, the user can easily visually check the reservation status of each equipment. Note that FIG. 19 shows an example in which the reservation screen is displayed in black and white for convenience of illustration, but the visual effect may be further enhanced by color display. For example, the reservation status is displayed with the characters “empty”, “done”, and “other”, but the frame in which this character is displayed is displayed in a different color (for example, “empty” is “ “White” and “Done” may be displayed in “Blue”, “Other” in “Gray”, and the like. In addition, to distinguish between “dedicated” and “non-dedicated”, the floor number and high vehicle name of “dedicated” materials and equipment are displayed in “blue”, and the floor number and height of “non-dedicated” materials and equipment are displayed. The car name may be displayed in “gray”.

  Then, the user can reserve each material and equipment and cancel the reservation on this reservation screen. For example, when the user clicks a frame in which the reservation status is “empty”, the control unit 104 of the reservation terminal 100 corresponds to the equipment ID of the material and equipment corresponding to the clicked frame and the clicked frame. Information indicating the reserved time zone and the user ID acquired at the time of login are transmitted to the server 110. Based on these pieces of information, the control unit 111 of the server 110 stores the reservation information in the corresponding part of the item “reservation” in the material / material DB 112b. Further, the control unit 104 of the reservation terminal 100 displays “Done” instead of “Empty” in the frame of the reservation screen clicked by the user. This completes the reservation. Alternatively, when the user clicks a frame whose reservation status is “completed”, the control unit 104 of the reservation terminal 100 corresponds to the equipment ID of the material and equipment corresponding to the clicked frame and the clicked frame. Information indicating the reserved time zone and the user ID acquired at the time of login are transmitted to the server 110. Based on these pieces of information, the control unit 111 of the server 110 deletes the reservation information stored in the corresponding part of the item “reservation” in the material / material DB 112b. Further, the control unit 104 of the reservation terminal 100 displays “empty” instead of “done” in the frame of the reservation screen clicked by the user. This completes the cancellation of the reservation. In this way, it becomes possible to easily reserve materials and equipment, so that the operating rate of materials and equipment can be increased. Alternatively, since it is possible to easily cancel the reservation of the equipment and materials, it becomes possible for other users to reserve the equipment and equipment, and the operating rate of the equipment can be increased.

  Further, the reservation screen is provided with a “MAP” button 123 for confirming the position of the equipment, and when the user clicks the “MAP” button 123, it corresponds to the “MAP” button 123. You can check the location of equipment. The specific method of confirming the position is arbitrary. For example, when the user clicks the “MAP” button 123, the equipment ID of the equipment corresponding to the “MAP” button 123 is sent from the reservation terminal 100 to the server 110. The control unit 111 of the server 110 converts the equipment ID using the conversion information prepared in advance in the equipment beacon ID of the first embodiment (for example, the equipment ID “EID0001” is converted into the equipment / equipment ID). The beacon ID “E0001” is converted), and the converted equipment beacon ID is transmitted to the server 50 of the first embodiment. The control unit 51 of the server 50 acquires an application display log corresponding to the equipment beacon ID and transmits it to the server 110. The control unit 111 of the server 110 identifies the position of the equipment based on the application display log, and displays a predetermined thumbnail indicating the equipment at a corresponding position on the drawing stored in the drawing DB 112c. Drawing information is generated, and this drawing information is transmitted to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays a drawing on the display 102 based on the drawing information. As a result, the user can easily visually confirm the position of each equipment.

  Further, the reservation screen is provided with a “return” button 124 for requesting the return of the equipment, and the user clicks the “return” button 124 to correspond to the “return” button 124. You can request a return of equipment. For example, when the user clicks the “return” button 124 corresponding to the equipment to be returned, the control unit 104 of the reservation terminal 100 sends the equipment ID of the equipment corresponding to the clicked “return” button 124 to the server 110. Send. The control unit 111 of the server 110 refers to the equipment / equipment DB 112b based on the equipment / equipment ID, and changes the information of the item “dedicated” corresponding to the equipment / equipment ID to “non-exclusive”. In addition, the control unit 111 of the server 110 is a predetermined format email requesting a return to the equipment manager based on a preset email address of the equipment manager, and the return is requested. Send an email containing the equipment ID of the equipment. This makes it possible to request the equipment / equipment manager to return the equipment / equipment that is no longer needed to the rental company, so that the equipment / equipment manager can return the unnecessary equipment / equipment in a timely manner. Cost can be reduced.

  The reservation screen is provided with a “position check” button 125 for confirming the position of the equipment. The user clicks on the “position confirmation” button 125 to confirm the position of the equipment. be able to. Although the specific method of this position confirmation is arbitrary, for example, when the user clicks the “position confirmation” button 125, a position confirmation request is transmitted from the reservation terminal 100 to the server 110, and the control unit 111 of the server 110 This position confirmation request is transmitted to the server 50 of the first embodiment. The control unit 111 of the server 110 acquires an application display log corresponding to each equipment beacon ID and transmits it to the server 110. The control unit 111 of the server 110 identifies the position of the equipment based on the application display log, and displays a predetermined thumbnail indicating the equipment at a corresponding position on the drawing stored in the drawing DB 112c. Drawing information is generated, and this drawing information is transmitted to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays a drawing on the display 102 based on the drawing information. As a result, the user can easily visually confirm the position of each equipment. At this time, for example, a drawing of a specific floor number is displayed, icons are displayed at the positions of all the equipment arranged on the floor number, and corresponding information (high vehicle name, reservation, etc.) If there is, the user name or company name of the reserved user is displayed. In addition, a pull-down menu for switching the floor number is displayed on the screen. When a floor number to be viewed is selected via the pull-down menu, the drawing can be switched to display the drawing of the selected floor number. As a result, the user can easily visually check the position of each equipment and make a reservation for the equipment with reference to this position.

  In addition, the reservation screen is provided with a “search for empty vehicle” button 126 for searching for an empty material and equipment. When the user clicks this “search for empty vehicle” button 126, You can search for equipment. For example, when the user clicks the “search for an empty vehicle” button 126, a search request is transmitted from the reservation terminal 100 to the server 110, and the control unit 111 of the server 110 generates search screen information and transmits it to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays a search screen on the display 102 based on the search screen information.

  FIG. 20 is a diagram illustrating a display example of the search screen. As shown in FIG. 20, the search screen is configured in substantially the same manner as the reservation screen, but in the upper part, a frame 130 for displaying the number of floors of the equipment to be searched and the number of floors of the equipment to be searched are selected. A drop-down list 131, a frame 132 for displaying the type of equipment to be searched, a drop-down list 133 for selecting the type of equipment to be searched, and a “search” button 134 for instructing a search are provided. When the user selects these floors and types and clicks the “search” button 134, these floors and types are transmitted to the control unit 111 of the server 110. The control unit 111 of this server 110 refers to the equipment / equipment DB 112b based on the number of floors and types, and identifies the equipment / equipment that matches these floors and types and has “empty” in the reservation status. Then, search screen information is generated based only on the information related to the specified equipment and is transmitted to the reservation terminal 100. As a result, the user can easily visually check the equipment that meets the conditions desired by the user, and can reserve the equipment with reference to this position. The search screen includes a “position check” button 135 having the same function as the “position check” button 125 in FIG. 19 and a “reserve” button 136. When the user clicks the button 136, the reservation screen of FIG. 19 can be returned.

(Processing-utilization rate identification processing)
Next, the operation rate specifying process for specifying the operation rate of materials and equipment will be described. When the user logs in the reservation terminal 100 in the same manner as the reservation process and then requests operation rate specification by an arbitrary method, the control unit 104 of the reservation terminal 100 transmits an operation rate specification request to the server 110. The control unit 111 of the server 110 refers to the server DB, calculates the operating rate of each material and equipment, and transmits the calculated operating rate to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays the operation rate on the display 102.

  As this operating rate, for example, two types of operating rates can be calculated and displayed. One operation rate is the dedicated period usage rate, and it is calculated from the dedicated period usage rate = the usage rate of materials and equipment / the dedicated rate of materials and equipment. Here, the usage rate of materials and equipment is a time ratio during which the materials and equipment were used during a predetermined period (for example, a period specified by the user at the time of requesting the operation rate, for one week or one month). , Utilization rate of materials and equipment = Calculated based on the time when materials and equipment were used / predetermined period. The time during which the equipment is used can be acquired from, for example, the server 50 according to the first embodiment. The equipment / equipment dedicated rate is the time ratio during which a material / equipment was “dedicated” for a predetermined period (for example, the period specified by the user at the time of requesting the operation rate, for one week or one month). , Utilization rate of materials and equipment = Calculated based on the time when the materials and equipment is “dedicated” / predetermined period. By grasping such a dedicated period usage rate, it is possible to easily and accurately grasp how much the equipment has been used during the period when the equipment is "dedicated". Returning low-cost materials and equipment to the rental company makes it possible to reduce the rental cost of materials and equipment.

  Another operation rate is a dedicated rate (free input dedicated rate), and is calculated as follows: dedicated rate = reservation dedicated period / total dedicated period. Here, the reservation-only period is a period during which the equipment is “dedicated” and reserved. The total dedicated period is the period during which the equipment has been “dedicated”. By grasping such a dedicated ratio, it becomes possible to easily and accurately grasp how much the equipment was reserved during the period when the equipment is "dedicated". By returning to the rental company, it becomes possible to reduce the rental cost of materials and equipment.
