The key beacon 60 is a key transmitter arranged at a position near the key for operating the equipment, and specifically, a key beacon ID for uniquely identifying itself is attached to the radio wave to surround the key beacon 60. Radio waves are transmitted in all directions of 360 °. Here, "placed near the key" means that the beacon 60 is placed with respect to the key at a short distance so that there is no problem even if the position of the key beacon 60 is equated with the position of the key. For example, a state in which the key beacon 60 is attached to the key via a connector 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. The key beacon 30 is arranged one by one in the vicinity of each key by the worker.

(processing)
Subsequently, the processing executed by the operating status specifying system of the materials and equipment according to the first embodiment will be described. In this system for specifying the operating status of materials and equipment, beacon registration processing, server DB update processing, application display log update processing, operating status specifying processing, and operating rate calculation processing are roughly executed.

(Processing-Beacon registration process)
First, the beacon registration process executed by the control unit 17 of the receiving terminal 10 according to the first embodiment will be described. In this beacon registration process, generally, a worker goes around the construction site while holding the receiving terminal 10, arranges a fixed beacon 20 at the construction site, and transmits information about the arranged fixed beacon 20 to the receiving terminal 10. This is a process 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 at the construction site. Subsequently, the worker registers the beacon ID and the transmission position information of the fixed beacon 20 arranged by the worker in the transmission position DB 52a of FIG. 6 by using the receiving terminal 10 possessed by the worker. The 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 when this icon is pressed by an operator, the beacon registration mode is set. In this mode, first, the setting of the drawing for which the fixed beacon 20 is registered is accepted. Specifically, the control unit 17 displays thumbnails of the drawing information stored corresponding to the item "drawing information" of the drawing DB 18b, and one of the 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 in the center of the screen. Then, the control unit 17 accepts the movement of the display position of the beacon icon. Specifically, for example, when the pressing of the arrow-shaped beacon movement icon (not shown) displayed on the display 12 is received, the beacon icon may be accepted in the direction indicated by the arrow, or the beacon icon of the beacon icon. When the display position is pressed by the worker's finger and the finger slide is accepted, the beacon icon may be moved along the slide. Then, when the confirmation icon (not shown) is pressed while the beacon icon is moved to the position where the fixed beacon 20 is installed, a window for accepting the input of the beacon ID is displayed. Then, the user inputs the beacon ID while confirming the beacon ID described in the fixed beacon 20, and when the beacon ID is input, the user identifies the beacon ID and the position of the beacon icon by a known method. It is transmitted to the server 50 in association with the transmission position information 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, the 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 of updating the server DB 52b to the latest version based on the signal transmitted from the receiving terminal 10 (hereinafter, log signal). The timing of executing this server DB update process is arbitrary, and may be executed, for example, when the power of the server 50 is turned on.

First, when the receiving terminal 10 receives the radio wave from the fixed beacon 20, the receiving terminal 10 identifies the 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 intensities are compared and the fixed beacon 20 having the strongest radio wave strength (that is, it exists in the vicinity of the receiving terminal 10 most). The fixed beacon ID of the fixed beacon 20) is specified. Next, the floor corresponding to the fixed beacon ID thus specified is specified from the drawing DB 18b shown in FIG.

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

Similarly, when the receiving terminal 10 receives the radio wave from the key beacon 60, the receiving terminal 10 identifies the key beacon ID (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 does not have to be specified.

Then, 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 obtains 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 a transmission process by the receiving terminal 10 may be executed at an arbitrary timing, and may be executed, for example, at a predetermined interval (for example, every 5 seconds). Then, when such a transmission process is similarly executed by the plurality of receiving terminals 10, log signals are transmitted from the plurality of receiving terminals 10 to the server DB 52b.

Then, the control unit 51 of the server 50 sequentially updates the server DB 52b every time the log signal from the reception terminal 10 is received. 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. Then, the information corresponding to the item "equipment beacon ID" is updated based on the material / equipment beacon ID included in the log signal, and the information corresponding to the item "fixed beacon ID" is updated based on the fixed beacon ID included in the log signal. Is updated, the information corresponding to the item "Key Beacon ID" is updated based on the key beacon ID included in the log signal, and the information corresponding to the item "Floor" is updated based on the floor included in the log signal. With reference to the transmission position DB 52a, the transmission position information corresponding to the fixed beacon ID included in the log signal is specified, and the information corresponding to the item "transmission position information" is updated based on the specified transmission position information, and the log is logged. The information corresponding to the item "Accuracy" is updated based on the radio wave reception strength contained in the signal. As a method for obtaining the accuracy, for example, the accuracy may be specified by referring to an accuracy specifying table (not shown) that stores the radio wave reception intensity and the accuracy in association with each other, but the method is not limited to this. Further, in the first embodiment, the accuracy is specified and stored on the server 50 side in this way, but the present invention is not limited to this, and the receiving terminal 10 obtains the accuracy and then includes the accuracy in the log signal and transmits the log. The accuracy contained in the signal may be stored. Further, the transmission position DB 52a may be provided in the receiving terminal 10, the transmission position information may be specified on the receiving terminal 10 side, and then the transmission may be attached to the log signal for transmission. This completes the server DB update process.

In this way, the control unit 51 of the server 50 is the receiving terminal 10 that moves together 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 a terminal position specifying means for specifying the position of the receiving terminal 10 that receives the radio wave from the material / equipment beacon 30 attached to the material / equipment. In addition, by updating the information corresponding to the item "accuracy" based on the log signal, the receiving terminal 10 and the material / equipment beacon 30 mutually interact with each other based on the radio wave reception intensity from the material / equipment beacon 30 of the receiving terminal 10. It functions as an estimated distance specifying means for specifying the estimated distance between them. Further, by updating the server DB 52b by associating the information of the item "transmission position information" and the information of the item "accuracy" with each other, the position of the receiving terminal 10 specified by the terminal position specifying means and the estimated distance specified at the position are specified. It functions as a log acquisition means for acquiring a log in which the estimated distance specified by the means is associated with each other.

(Processing-App display log update processing)
Subsequently, the 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 the process, the 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. The timing of executing this application display log update process is arbitrary, and may be executed, for example, when the power of the server 50 is turned on.

In SA1, the control unit 51 of the server 50 determines whether or not a log signal regarding the position of the equipment is received. The specific method of this determination is arbitrary. For example, when the item "equipment / equipment beacon ID" of the server DB 52b is referred to and information including the equipment / equipment beacon ID is newly stored, a log signal regarding the position of the equipment / equipment is output. Judge that it has been acquired. Even if a log signal is received from the receiving terminal 10, for example, if the log signal does not include the material / equipment beacon ID, there is no information regarding the position of the material / equipment. Then, it waits until the log signal regarding the position of the equipment is received (SA1, No), and when it is received (SA1, Yes), it shifts to SA2.

In SA2, the control unit 51 of the server 50 adds a log to the equipment / 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 material / equipment position log table 52c, and the added record item "material / equipment beacon ID", item "time", and item "transmission". In the "location information" and the item "accuracy", the information corresponding to the item having the same name in the server DB 52b is sorted and stored in chronological order for each material / equipment beacon ID.

In SA3, the control unit 51 of the server 50 has an elapsed time t1 from the time of the log added in the previous processing of SA2 (hereinafter, the previous log) to the time of the log added in the current processing of SA2 (hereinafter, the current log). Is calculated. Specifically, with reference to the material / 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 used as 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 by SA3 is 1 minute or less. Although it was set to 1 minute in the first embodiment, this time is merely an example, and any time such as 3 minutes or 5 minutes can be applied. Then, when the elapsed time t1 is not 1 minute or less (SA4, No), it shifts to SA5, and when the elapsed time t1 is 1 minute or less (SA4, Yes), it shifts to SA7.

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

In SA6, the control unit 51 of the server 50 generates a new timepack log. For example, in the above example, the time pack log having the transmission position coordinates (X002, Y001) and the accuracy (20) of the current log (L08) is added to the lower end of the time pack log table 52d of FIG. When a new time pack log (hereinafter, "current time pack log") is created in this way, the current time pack log and the previously generated time pack log (hereinafter, "previous time pack log") will be used thereafter. The app display log will be updated based on the comparison. The details of updating this 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 of the material / 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 the other logs up to the log having the 0 flag before the current log. For example, assuming that the current log is L07, the accuracy of the logs (that is, L05 and L06) up to L05 having the 0 flag before L07 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 less than or equal to the accuracy of all the other logs compared. For example, in the above example, since the accuracy (40) of L07 is not less than or equal to the accuracy (30) of L06, it is determined that the accuracy of the current log is not less than or equal to the accuracy of all the compared logs. Then, when 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 at a position closer to the equipment than the existing log. , It is assumed that the current log is more suitable for indicating the position of equipment and materials, and the time pack log is moved to SA10 to be overwritten by 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 at a position 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 materials, and the application display log update process is terminated without overwriting the time pack log.

In the 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. In this way, the control unit 51 of the server 50 overwrites the current time pack log with a log having a smaller accuracy among the plurality of logs, so that the log acquisition means within a predetermined time range (in the first embodiment, the present embodiment 1). As described above in SA4, it functions as a log identification means for identifying the time pack log, which is the log indicating the smallest estimated distance, from the plurality of logs acquired in 1 minute).

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

In the SA12, the control unit 51 of the server 50 determines whether or not the elapsed time t2 calculated by the SA11 is equal to or longer than a predetermined time (1 day in the present embodiment). Then, when the elapsed time t2 is one day or more (SA12, Yes), the information in the previous timepack log is old and less useful, so the process shifts to SA15 in order to overwrite it with the current timepack log. On the other hand, if the elapsed time t2 is not one day or more (SA12, No), the information in the previous time pack log is assumed to be not old, and the one with higher usefulness should be selected from the current time pack log and the previous time pack log. , SA13. In the first embodiment, one day is set as a criterion for determining whether or not the time pack log information is old, but 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, the elapsed time t2 from the previous time pack log (L02) to the current time pack log (L06) is 5 minutes, and it is determined that it 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 item "accuracy" in the time pack log table 52d shown in FIG. 8 is referred to for comparison.

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, since the accuracy of the current time pack log is 30 and the accuracy of the previous time pack log is 10, it is determined that the accuracy is not less than or equal to the accuracy of the previous time pack log. Then, when 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 equipment and materials, and the system shifts to SA15 in order to update the application display log to the current time pack log. On the other hand, if 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 closer to the equipment beacon 30 than the current time pack log. It is a log and is suitable for indicating the position of equipment and materials, and the application display log processing is terminated without updating the application display log and leaving the previous time pack log as it is. In this way, the control unit 51 of the server 50 specifies the application display log by comparing the time pack logs, and based on the time pack log specified by the log specifying means, the target position for specifying the position of the equipment and materials. Functions as a specific means.

In SA15, the control unit 51 of the server 50 overwrites the application display log with the current time pack log. That is, when the elapsed time t2 is one day or more (SA12, Yes), the information in the previous time pack log is old and less useful, 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. It is assumed that the log is suitable for indicating the position of equipment and materials, and the application display log is overwritten with the current time pack log. This is the end of the explanation of the application display log update process.

(Processing-Operation status identification process)
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 roughly identifying whether or not the equipment is operating (operating status) based on the information from the material / equipment beacon 30 and the key beacon 60. The timing of executing this operation status specifying process is arbitrary, and may be executed, for example, when the power 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 regarding the key position has been received. The specific method of this determination is arbitrary. For example, when the item "key beacon ID" of the server DB 52b is referred to and information including the key beacon ID is newly stored, a log signal regarding the position of the key is acquired. judge. Then, it waits until the log signal is received (SB1, No), and when the log signal is received (SB1, Yes), it shifts 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" in the key position log table 52e, and the added record items "equipment beacon ID", item "time", and item " The information corresponding to the item having the same name in the server DB 52b is sorted and stored in the "transmission position information" for each material / equipment beacon ID in chronological order. In addition, for the item "approach determination flag", the item "transmission position coordinates" of the server DB 52b is referred to, and the positions of the materials and equipment at the peripheral time of the current time (for example, 3 minutes before and after) are extracted to obtain the key position. If the positions of the materials and equipment are within a predetermined distance, it is determined that they are approaching and "1" is stored, and if they are not within a predetermined distance, it is determined that they are not approaching and "0" is stored. Here, the specific method for determining whether or not the key and the equipment are within a 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. Or, if they exist in the vicinity of the same fixed beacon 20, it may be determined that they are close to each other. However, the method is not limited to this method. For example, the positions of the key beacon 60 and the equipment beacon 30 are specified based on the radio wave intensity from each beacon, the distance between these positions is calculated, and this calculated distance is calculated. May be determined whether is within a predetermined distance (for example, 5 m).

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

In SB4, the control unit 51 of the server 50 specifies the operating status of the materials and equipment. Specifically, among the information stored in the key time pack log table 52f updated in SB3, the latest key time pack log (log of determination ID 001 in FIG. 9) is referred to, and the item "pack approach determination" is performed. If "1" is stored in the flag, it is determined to be "operating", and if "0" is stored, it is determined to be "non-operating". As described above, in the present embodiment, since the operating status is determined by referring to the key time pack log in which a plurality of key logs are combined into one, the position coordinates are erroneously detected for some reason such as a communication failure. It is possible to eliminate the erroneous judgment caused by judging the operating status based on one key log. This completes the operation status identification process.

(Processing-Operating rate calculation processing)
Next, the operating rate calculation process executed by the control unit 51 of the server 50 according to the first embodiment will be described. This operating rate calculation process is a process for grasping unused materials and equipment and reducing the rental cost of the materials and equipment by roughly calculating the operating rates of a plurality of materials and equipment. The timing of executing this operation rate calculation process is arbitrary, and may be executed by the control unit 51 of the server 50 at a predetermined timing, for example, once a day or once every half a 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 in operation (that is, "1" is added to the item "key time pack log"). The number of stored logs) and the number of logs in which the equipment is in a non-operating state (that is, the number of logs in which "0" is stored in the item "key timepack log") are calculated. Next, the operating rate of materials and equipment is calculated based on the following formula (1).
R = n _on / (n _on + no _off ) ... (1)
here,
R = availability of materials and equipment,
n _on = log the number of materials and equipment is in a working state,
no _off = Number of logs when equipment and materials are not in operation.
For example, in the example of FIG. _9, an _{n on} = _2, is _{n off = 1, R = 2} /3 ( i.e., about 66.7%) is. Use the same procedure to calculate the operating rate of all materials and equipment.

Next, the calculated operating rates of the materials and equipment are arranged in descending order, and the operating rate table 52 g shown in FIG. 10 is updated. At this time, as the information corresponding to the item "rank", a number indicating the rank (1 to 5 in the present embodiment) is stored in advance, and for the item "type", the material and equipment for which the operating rate is specified. You may obtain it by referring to the material / equipment DB18c based on the material / equipment beacon ID of. For the item "availability", the availability of the materials and equipment specified above is stored. 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 operating rate of materials and equipment can be visualized at the same time, for example, materials and equipment with low operating rates can be easily found from a wide construction site and returned, improving the convenience of workers and reducing construction costs. Can be reduced.

(Effect of Embodiment 1)
As described above, according to the material / equipment operation status identification system of the first embodiment, the material / equipment operation status is specified based on the information transmitted from the material / equipment beacon 30, so that the position of the material / equipment is specified. The operating status of the materials and equipment can be easily specified by using the material and equipment beacon 30 for the purpose, and the increase in construction cost due to the use of an unnecessary number of materials and equipment can be suppressed.

In addition, since the operating status of the equipment is specified based on the radio waves from the key transmitter and the material / equipment beacon 30, the material / equipment is in the operating state based on the fact that the key of the material / equipment is located near the material / equipment. It can be easily identified and the convenience is improved.

In addition, since the operating rate of materials and equipment is calculated as the operating status of materials and equipment, the operating status of materials and equipment can be easily grasped as a numerical value, and the operating 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 that identifies that the equipment is in operation is included in the plurality of key logs, it is considered that the equipment is in operation, so that the equipment is in operation. Even if there is an omission in the acquisition of the key log indicating, it can be determined that the key log is in operation by supplementing it with another key log, and the specific accuracy is improved.

For example, in the "sky" indicated by the reference numeral 120 in FIG. 19, the equipment and materials with the high vehicle name "9m3" arranged on the floor number "2" have the reserved time of "morning" on the date "November 15". In the obi, it indicates that no reservation has been made. Further, for example, "Done" indicated by reference numeral 121 in FIG. 19 is reserved for the "afternoon" of the date "November 15" by the equipment and materials of the high vehicle name "9m3" arranged on the floor number "2". It indicates that the reservation is made by the logged-in user "Yoshida" or another user of the same company "○○ Co., Ltd." as the user "Yoshida" in the time zone. Alternatively, for example, the “other” indicated by the reference numeral 122 in FIG. 19 is reserved for the “morning” of the date “November 16” by the equipment of the high vehicle name “9m3” located on the floor number “2”. It shows that the reservation is made by a user of a company other than the same company "○○ Co., Ltd." as the logged-in user "Yoshida" in the time zone. These information are specified and displayed by the control unit 111 of the server 110 when the reservation screen is generated, based on the information corresponding to the item "reservation" of the material / equipment DB 112b of FIG. 18 and the information input from the user at the time of login. To log in. For example, if "20171114am-UID0001" is stored as the information corresponding to the item "reservation" and the user ID "UID0001" is acquired as the information input by the user at the time of login, the date "November 14" Since it can be identified that the reservation is made by the user who is logged in to the reservation time zone of "AM" of "Sun", "Done" is displayed in the corresponding part of the reservation screen. Alternatively, when the user ID included in the information corresponding to the item "reservation" and the user ID included in the information input by the user at the time of login do not match, or by referring to the user DB 112a based on each of these user IDs. If the specified company names do not match, "Other" is displayed in the corresponding part of the reservation screen. Alternatively, for the reservation time zone that is not included in the information corresponding to the item "reservation" of the equipment DB 112b, "empty" is displayed in the corresponding part of the reservation screen. However, any known structure or method can be adopted for the specific method of storing the reservation information, the reservation time zone, or the like. As a result, the user can easily visually confirm the reservation status of each material and equipment. Although FIG. 19 shows an example in which the reservation screen is displayed in black and white for convenience of illustration, the visual effect may be further enhanced by displaying in color. For example, the reservation status is displayed with the characters "empty", "finished", and "other", but the frame in which these characters are displayed is displayed in a different color depending on the reservation status (for example, "empty" is "empty". "White" and "finished" may be displayed as "blue", and "other" may be displayed as "gray"). In addition, in order to distinguish between "dedicated" and "non-dedicated", the number of floors and high vehicle names are displayed in "blue" for "dedicated" materials and equipment, and the number of floors and high for "non-dedicated" materials and equipment. The vehicle name may be displayed in "gray".

Then, the user can make a reservation for each material / equipment or cancel the reservation on this reservation screen. For example, when the user clicks a frame whose reservation status is "empty", the control unit 104 of the reservation terminal 100 corresponds to the material / equipment ID of the material / equipment corresponding to the clicked frame and the material / equipment ID corresponding to the clicked frame. The information indicating the reserved time zone and the user ID acquired at the time of login are transmitted to the server 110. Based on this information, the control unit 111 of the server 110 stores the reservation information in the corresponding place of the item "reservation" of the equipment 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 material / equipment ID of the material / equipment corresponding to the clicked frame and the material / equipment ID corresponding to the clicked frame. The information indicating the reserved time zone and the user ID acquired at the time of login are transmitted to the server 110. Based on this information, the control unit 111 of the server 110 deletes the reservation information stored in the corresponding part of the item "reservation" of the equipment 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 the reservation of materials and equipment can be easily canceled, other users can reserve the materials and equipment, and the operating rate of the materials and equipment can be increased.

Further, the reservation screen is provided with a "MAP" button 123 for confirming the position of the equipment and materials, and when the user clicks the "MAP" button 123, the "MAP" button 123 is supported. You can check the position of materials and equipment. The specific method of this position confirmation is arbitrary, but for example, when the user clicks the "MAP" button 123, the material / equipment ID of the material / equipment corresponding to the "MAP" button 123 is transmitted from the reservation terminal 100 to the server 110. After being transmitted, the control unit 111 of the server 110 converts the material / equipment ID using the conversion information prepared in advance for the material / equipment beacon ID of the first embodiment (for example, the material / equipment ID “EID0001” is converted into the material / equipment. It is converted to the beacon ID "E0001"), and the converted material / equipment beacon ID is transmitted to the server 50 of the first embodiment. The control unit 51 of the server 50 acquires the application display log corresponding to the material / equipment beacon ID and transmits it to the server 110. The control unit 111 of the server 110 identifies the position of the material / equipment based on the application display log, and superimposes and displays a predetermined thumbnail indicating the material / equipment on the 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 the drawing on the display 102 based on the drawing information. As a result, the user can easily visually confirm the position of each material and equipment.

In addition, the reservation screen is provided with a "return" button 124 for requesting the return of materials and equipment, and when the user clicks the "return" button 124, the "return" button 124 is supported. You can request the return of materials and equipment. For example, when the user clicks the "return" button 124 corresponding to the material / equipment to be returned, the control unit 104 of the reservation terminal 100 transfers the material / equipment ID of the material / equipment corresponding to the clicked "return" button 124 to the server 110. Send. The control unit 111 of the server 110 refers to the material / equipment DB 112b based on the material / equipment ID, and changes the information of the item “dedicated” corresponding to the material / equipment ID to “non-dedicated”. Further, the control unit 111 of the server 110 is a predetermined format e-mail requesting the material / equipment manager to return the e-mail based on the preset e-mail address of the material / equipment manager, and the return is requested. Send an email containing the equipment ID of the equipment. As a result, it is possible to request the equipment manager to return the unnecessary equipment to the rental company, so that the equipment manager can return the unnecessary equipment in a timely manner and rent the equipment. The cost can be suppressed.

In addition, the reservation screen is provided with a "position confirmation" button 125 for confirming the position of the equipment and materials, and the user clicks the "position confirmation" button 125 to confirm the position of the equipment and materials. be able to. The specific method of this position confirmation is arbitrary, but for example, when the user clicks the "position confirmation" button 125, the position confirmation request is transmitted from the reservation terminal 100 to the server 110, and the control unit 111 of the server 110 receives. This position confirmation request is transmitted to the server 50 of the first embodiment. The control unit 111 of the server 110 acquires the application display log corresponding to each material / equipment beacon ID and transmits it to the server 110. The control unit 111 of the server 110 identifies the position of the material / equipment based on the application display log, and superimposes and displays a predetermined thumbnail indicating the material / equipment on the 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 the drawing on the display 102 based on the drawing information. As a result, the user can easily visually confirm the position of each material and equipment. At this time, for example, a drawing of a specific floor number is displayed, an icon is displayed at each position of all the materials and equipment arranged on the floor number, and the corresponding information (high vehicle name and reservation) is displayed. If there is, the user name, company name, etc. of the reserved user) is displayed. In addition, a pull-down menu for switching the number of floors is displayed on this screen, and when the number of floors for which the drawing is desired to be viewed is selected via this pull-down menu, the display of the drawing for the selected number of floors can be switched. As a result, the user can easily visually confirm the position of each material and equipment, and can reserve the material and equipment with reference to this position.

In addition, the reservation screen is provided with a "find vacant vehicle" button 126 for searching for vacant equipment, and when the user clicks this "find vacant vehicle" button 126, vacant equipment is provided. You can search for equipment. For example, when the user clicks the "search for 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 the search screen on the display 102 based on the search screen information.

FIG. 20 is a diagram showing 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 above, the frame 130 for displaying the floor number of the material / equipment to be searched and the floor number of the material / 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. Then, 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. By referring to the equipment DB 112b based on these floors and types, the control unit 111 of the server 110 identifies the materials and equipment that match these floors and types and have "empty" in the reservation status. Then, the search screen information is generated based only on the information about the specified equipment and materials and transmitted to the reservation terminal 100. As a result, the user can easily visually confirm the materials and equipment that meet the conditions desired by the user, and can reserve the materials and equipment with reference to this position. The search screen is provided with a "position confirmation" button 135 having the same function as the "position confirmation" button 125 in FIG. 19, and a "reserve" button 136, which is "reserved". The user can return to the reservation screen of FIG. 19 by clicking the button 136.

(Processing-Operating rate identification processing)
Next, the operating rate specifying process for specifying the operating rate of materials and equipment will be described. When the user requests the operation rate specification by an arbitrary method after logging in to the reservation terminal 100 in the same manner as the reservation process, the control unit 104 of the reservation terminal 100 transmits the 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 operating rate on the display 102.

As this operating rate, for example, two types of operating rates can be calculated and displayed. One operating rate is the dedicated period usage rate, which is calculated by the dedicated period usage rate = material / equipment usage rate / material / equipment dedicated rate. Here, the usage rate of materials and equipment is the time ratio during which the materials and equipment were used for a predetermined period (for example, a period specified by the user at the time of a specific request for the operating rate, which is one week or one month). , Material / equipment utilization rate = Calculated based on the time that the material / equipment was used / the specified period. The time during which the materials and equipment have been used can be obtained from, for example, the server 50 of the first embodiment. The dedicated rate of materials and equipment is the time ratio during which the materials and equipment were "dedicated" during a predetermined period (for example, the period specified by the user at the time of a specific request for the operating rate, which is one week or one month). , Material / equipment utilization rate = Calculated based on the time / specified period when the material / equipment was "dedicated". By grasping such a dedicated period usage rate, it becomes possible to easily and accurately grasp how much equipment and materials were used during the "dedicated" period, and the dedicated period usage rate can be reduced. By returning low-priced materials and equipment to the rental company, it is possible to reduce the rental cost of materials and equipment.

The other occupancy rate is the dedicated rate (vacant input dedicated rate), which is calculated by the dedicated rate = reservation dedicated period / total dedicated period. Here, the reservation-only period is a period in which materials and equipment are "dedicated" and reserved. The full-dedicated period is the period during which the equipment was "dedicated". By grasping such a dedicated rate, it becomes possible to easily and accurately grasp how much the equipment was reserved during the period when the equipment is "dedicated", and for materials and equipment with a low dedicated rate. By returning it to the rental company, it will be possible to reduce the rental cost of equipment and materials.

[III] Modifications to the Embodiment The embodiments according to the present invention have been described above, but the specific configuration and means of the present invention are within the scope of the technical idea of each invention described in the claims. Can be arbitrarily modified and improved. Hereinafter, such a modification will be described.

(About the problem to be solved and the effect of the invention)
First, the problem to be solved by the invention and the effect of the invention are not limited to the above-mentioned contents, and may differ depending on the implementation environment and the details of the configuration of the invention, and only a part of the above-mentioned problems. May be resolved or only some of the effects described above may be achieved.

(About distribution and integration)
Further, each of the above-mentioned electrical components is a functional concept, and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of distribution or integration of each part is not limited to the one shown in the figure, and all or part of the parts may be functionally or physically dispersed or integrated in arbitrary units according to various loads and usage conditions. Can be configured. For example, in each embodiment, the server 50 may include a part of the functions provided in the receiving terminal 10, or the receiving terminal 10 may provide a part of the functions provided in the server 50.

(About position)
In each embodiment, the two-dimensional position coordinates are specified, stored and displayed as the position coordinates, but the three-dimensional position coordinates including the position in the height direction may be stored and displayed. For example, the height position coordinates corresponding to each drawing (for example, (Z010) for the first floor, (Z020) for the second floor, etc.) are stored in the drawing DB 18b, and are based on the height position coordinates. May be specified.

(About receiving terminal)
In the present embodiment, the case where all the workers have the receiving terminal 10 has been described, but the present invention is not limited to this, and only the site manager may have the receiving terminal 10 or a part of the workers. May possess a beacon instead of the receiving terminal 10 and specify the position in the same manner as the equipment.

(About equipment beacons)
If there is a material / equipment beacon 30 that has not received radio waves for a predetermined time or more (for example, one day or more), the worker may be urged to confirm the material / equipment. For example, referring to the item "time" in the material / equipment position log table 52c, if the latest log is a predetermined time (for example, one day) before the current time, the material / equipment beacon of the material / equipment beacon 30 is used. A signal with an ID may be transmitted to the receiving terminal 10, and the receiving terminal 10 receiving this signal may highlight the material / equipment icon I2 of the material / equipment (for example, display in a color different from other beacons). ..

(Regarding specific aspects of materials and equipment)
In each embodiment, the method of specifying the operating status of the aerial work platform as materials and equipment has been described, but the operating status of other types of materials and equipment can also be specified in the same specific manner. In addition, the operating status may be specified in different specific modes depending on the type of equipment. For example, when specifying the operating status of an elevator, a material / equipment beacon 30 is attached to the elevator, and radio waves from the material / equipment beacon 30 are transmitted to receiving terminals existing on a plurality of floors within a predetermined time (for example, 10 minutes). When the radio wave is received, it may be determined that the elevator is moving across the floor and is in operation. According to such a modification, since the operating status of the equipment is specified in a specific mode different depending on the type of the material and equipment, the operating status can be specified and specified in the optimum mode according to the type of the material and equipment. Accuracy and speed are improved.

(About magnetic sensor and barometric pressure sensor)
In the second embodiment, an example in which the detection signal of the magnetic sensor 73 is transmitted to the receiving terminal via the material / equipment beacon 30 will be described, and in the third embodiment, the detection signal of the pressure sensor will be received via the material / equipment beacon 30. Although the example of transmitting to the terminal has been described, the detection signals of the magnetic sensor 73 and the pressure sensor may be transmitted to the receiving terminal via any other relay device without passing through the material / equipment beacon 30. , May be sent directly to the receiving terminal.

(About other sensors)
Although the operating status of the equipment is specified by using the magnetic sensor in the second embodiment and the barometric pressure sensor in the third embodiment, other sensors may be used. For example, the operating status of the equipment may be specified from the vibration status of the equipment using a vibration sensor. Since some vibration occurs in the equipment when the equipment is started or used, if the vibration sensor transmits radio waves including the operation flag-on information when the vibration is detected, the equipment is operated in the same manner as in the second and third embodiments. The situation can be identified.

(About calculation and output of operating status)
The system for specifying the operating status of the materials and equipment according to the fourth embodiment has been described as a system separate from the system for specifying the operating status of the materials and equipment according to the first to third embodiments. Some may be integrated. For example, the server 50 of FIG. 2 and the server 110 of FIG. 16 may be integrated, or the receiving terminal 10 of FIG. 2 and the reservation terminal 100 of FIG. 16 may be integrated. In these cases, by holding the information for associating the material / equipment beacon ID described in the first to third embodiments and the material / equipment ID described in the fourth embodiment with each other, the first to third embodiments are held. The operating rate of each material and equipment calculated in (hereinafter, transmitter operating rate) and the operating rate of each material and equipment calculated in the fourth embodiment (hereinafter, reserved operating rate) are associated with the same material and equipment. Can be done. Then, for example, by calculating the ratio of the transmitter operating rate to the reserved operating rate, the ratio of materials and equipment reserved and actually operating (actual operating rate) can be obtained, or the actual operating rate can be calculated from 100%. By subtracting, it is possible to obtain the ratio (empty reservation rate) that is not actually operating even though the materials and equipment are reserved, and it is possible to compensate for the low accuracy of the transmitter operation rate. It will be possible to evaluate the operating rate from a wider variety of perspectives.
