Air pressure sensor 1202 detects the air pressure at the location where work vehicle sensor device 12 is installed.

The acceleration sensor 1203 is a sensor that detects acceleration. Acceleration sensor 1203 detects the acceleration of work vehicle sensor device 12 . Since the acceleration sensor 1203 is installed on the aerial work platform 11 of the work vehicle 1, even if the work vehicle 1 is not moving, if the aerial work platform 11 is raised or lowered, the acceleration sensor 1203 will be detected by the aerial work platform 11. to detect the acceleration of

Note that the microcomputer 1201 does not have to transmit the detection value of the acceleration sensor 1203 if it is less than a preset threshold value. The work vehicle sensor device 12 may be set, for example, to generate an interrupt when a value indicating acceleration detected by the acceleration sensor 1203 is greater than or equal to a threshold. Then, when an interrupt occurs, the microcomputer 1201 associates the detection value indicating the atmospheric pressure detected by the atmospheric pressure sensor 1202 and the detected value indicating acceleration detected by the acceleration sensor 1203 with the vehicle name of the work vehicle 1 and transmits them to the server 2 . may Further, when no interrupt has occurred, the microcomputer 1201 associates the detected value indicating the atmospheric pressure by the atmospheric pressure sensor 1202 with the vehicle name of the work vehicle 1 and transmits it to the server 2 via the first communication unit 204 . may

The microcomputer 1201 transmits the value indicating the atmospheric pressure detected by the atmospheric pressure sensor 1202 to the server 2 via the first communication unit 204 at predetermined intervals (for example, every 5 seconds). Since the reference sensor device 13 receives power from the outlet installed in the building 4 as described above, power saving need not be taken into consideration. Therefore, the reference sensor device 13 can detect the air pressure at shorter intervals than the work vehicle sensor device 12 and transmit a detection value indicating the detected air pressure.

For example, by registering a comment such as "hope to use from XX day" in the "comment", the work vehicle 1 can be dispatched in consideration of the comment in the coordination meeting. "Personal name" is an example of "worker name".

The calculator 21 calculates the air pressure corresponding to each floor of the building 4 . When the calculation unit 21 receives the detected value of atmospheric pressure from the reference sensor device 13, the detected value received from the reference sensor device 13 is used as the atmospheric pressure corresponding to the floor on which the reference sensor device 13 is installed in the floor number/air pressure management table 261. Stores the indicated barometric pressure. The floor on which the reference sensor device 13 is installed is stored in advance in the auxiliary storage unit 203, for example. FIG. 8 is a diagram showing an example of the floor/atmospheric pressure management table 261 in which the atmospheric pressure indicated by the detected value received from the reference sensor device 13 is stored. In this embodiment, since the reference sensor device 13 is installed on the first floor of the building 4, the atmospheric pressure indicated by the detection value received from the reference sensor device 13 is stored in association with the first floor in the floor number/atmospheric pressure management table 261. It is

The calculator 21 calculates the atmospheric pressure on each floor of the building 4 based on the atmospheric pressure indicated by the detection value received from the reference sensor device 13 . For calculation of atmospheric pressure, for example, various known calculation methods can be employed using the height associated with each floor in the floor/atmospheric pressure management table 261 and the atmospheric pressure indicated by the detected value received from the reference sensor device 13. can.

As an example of the calculation method for calculating the atmospheric pressure, the calculation method described below can be cited. The height per 1 hPa of atmospheric pressure varies according to the altitude of the construction site where the building 4 is constructed. For example, 8.3 (m/hPa) at an altitude of 0m, 9.1 (m/hPa) at an altitude of 1000m, 10.1 (m/hPa) at an altitude of 2000m, and 11.2 (m/hPa) at an altitude of 3000m. be. Therefore, it is preferable to select the air pressure corresponding to the height of 1 m according to the altitude of the construction site where the building 4 is constructed.

In this embodiment, 8.4 (m/hPa) is selected assuming that the altitude of the construction site where the building 4 is to be constructed is several tens of meters to several hundreds of meters. Then, the calculating unit 21 calculates the atmospheric pressure corresponding to each floor by dividing the height difference (m) between the floor where the reference sensor device 13 is installed and each floor in the building 4 by 8.4 (m/hPa). be able to.

FIG. 9 is a diagram showing an example of the floor number/atmospheric pressure management table 261 after the calculation unit 21 has calculated the atmospheric pressure corresponding to each floor of the building 4 based on the atmospheric pressure indicated by the detection value received from the reference sensor device 13 . . The atmospheric pressure corresponding to each of the 2nd to 13th floors of the building 4 is calculated by the calculator 21 , and the calculated atmospheric pressure is stored in the floor/air pressure management table 261 . As a result of the calculation by the calculator 21, each floor of the building 4 is associated with the atmospheric pressure. A detection value is transmitted from the reference sensor device 13 at intervals of 5 seconds. Therefore, each time the calculation unit 21 receives a detection value from the reference sensor device 13, the calculation unit 21 calculates the pressure corresponding to each floor of the building 4 based on the pressure indicated by the newly received detection value, and calculates the floor number/pressure management table. H.261 may be updated.

The position acquisition unit 22 acquires the position of the work vehicle 1 based on the air pressure detected by the work vehicle sensor device 12 . The position acquisition unit 22 receives from the work vehicle sensor device 12 a detection value indicating the air pressure detected by the air pressure sensor 1202 . The position acquisition unit 22 refers to the floor/air pressure management table 261 to acquire the floor number corresponding to the air pressure indicated by the detection value received from the work vehicle sensor device 12 . The position acquisition unit 22 may set the acquired floor number as the position of the work vehicle 1 . The position acquisition unit 22 stores the number of floors where the work vehicle 1 exists in the work vehicle management table 262 in association with the vehicle name of the work vehicle 1 .

The work vehicle sensor device 12 is provided on the high work platform 11 of the work vehicle 1 as described above. Therefore, when the aerial work platform 11 is near the ceiling, the atmospheric pressure indicated by the detection value received from the work vehicle sensor device 12 is close to the atmospheric pressure corresponding to the floor above the floor on which the work vehicle 1 exists. is also conceivable. Therefore, in the floor number/atmospheric pressure management table 261, if the floor associated with the atmospheric pressure closest to the atmospheric pressure indicated by the detection value received from the work vehicle sensor device 12 is determined to be the floor on which the work vehicle 1 exists, the work vehicle 1 position may be erroneously detected. Therefore, the position acquisition unit 22 determines that the atmospheric pressure indicated by the detection value received from the work vehicle sensor device 12 is equal to or higher than the atmospheric pressure associated with a certain floor, and is associated with a floor one floor higher than the certain floor. If it is less than atmospheric pressure, it may be determined that the work vehicle 1 exists on the certain floor.

The operating status acquisition unit 23 acquires the operating status of the work vehicle 1 based on the acceleration detected by the work vehicle sensor device 12 . The operating status acquisition unit 23 receives from the work vehicle sensor device 12 a detection value indicating the acceleration detected by the acceleration sensor 1203 . The operating status acquisition unit 23 determines that the work vehicle 1 is operating when the received detection value indicating the acceleration is equal to or greater than the threshold. Further, the operating status acquisition unit 23 determines that the work vehicle 1 is not operating when the received detection value indicating the acceleration is less than the threshold. The operating status acquisition unit 23 stores the determined operating status in the work vehicle management table 262 in association with the vehicle name of the work vehicle 1 .

The usage accepting unit 24 accepts usage registration that associates the work vehicle 1 with the name of the worker who uses the work vehicle 1 . The usage reception unit 24 transmits a usage reception screen to the tablet terminal 3 in response to a request from the tablet terminal 3, for example.

The operating status 2534 indicates the operating status of the work vehicle 1 two days ago. The operating status 2535 indicates the operating status of the work vehicle 1 three days ago. The operating status confirmation screen 252 can show the operating status of the work vehicle 1 for four days including the current day using an operating status 2532, an operating status 2533, an operating status 2534, and an operating status 2535.

A comment mark 2536 is a mark displayed when there is a comment associated with the work vehicle 1 in the usage status management table 263 . For example, when a comment mark 2536 is specified, a comment stored in the usage status management table 263 is displayed in a balloon or the like. The warning mark 2537 is a mark that is displayed when detection values from the work vehicle sensor device 12 have not been received for three days or longer. By displaying the alert mark 2537, it becomes possible to recognize the possibility that there is an abnormality in communication.

(Processing Flow of Reference Sensor Device 13)
FIG. 18 is a diagram showing an example of the processing flow of the reference sensor device 13. As shown in FIG. An example of the processing flow of the reference sensor device 13 will be described below with reference to FIG.

At T1, initialization is performed. In the initial settings, for example, calibration of the air pressure sensor 1202 and registration of the server 2 to which detection values are to be sent are performed. Details of the calibration will be described later.

At T2, barometric pressure sensor 1202 measures barometric pressure. At T3, the microcomputer 1201 transmits to the server 2 via the first communication unit 204 the detection value indicating the air pressure measured by the air pressure sensor 1202 at T2.

At T4, the microcomputer 1201 determines whether 5 seconds have passed since the last transmission of the detected value. If 5 seconds have passed (YES at T4), the process returns to T2 to measure the atmospheric pressure (T2) and transmit the detected value (T3). If 5 seconds have not elapsed (NO at T4), the process of T4 is repeated.

At T11, initialization is performed. In the initial settings, for example, the calibration of the air pressure sensor 1202 and the acceleration sensor 1203 and the registration of the server 2 to which detection values are to be transmitted are performed. Also, a threshold for generating an interrupt (threshold for the detection value of the acceleration sensor 1203) is set. Details of the calibration will be described later.

At T12, barometric pressure sensor 1202 measures barometric pressure. Also, the acceleration sensor 1203 measures acceleration. If an interrupt occurs, that is, if the detected value indicating the acceleration detected at T12 is greater than or equal to the threshold value (YES at T13), the process proceeds to T14. If no interrupt occurs, that is, if the detection value indicating the acceleration detected at T12 is less than the threshold (NO at T13), the process proceeds to T15.

At T14, the microcomputer 1201 transmits to the server 2 via the first communication unit 204 the detection value indicating the air pressure measured by the air pressure sensor 1202 and the detection value indicating the acceleration measured by the acceleration sensor 1203 at T12.

At T15, the detection value indicating the air pressure measured by the air pressure sensor 1202 at T12 is transmitted to the server 2 via the first communication unit 204. FIG.

At T16, the microcomputer 1201 determines whether the switch 1205 has been pressed. If pressed (YES in T16), the process returns to T12 to measure atmospheric pressure and acceleration (T12) and transmit detected values (T14, T15). If not pressed (NO in T16), the process proceeds to T15.

At T17, the microcomputer 1201 determines whether or not 60 minutes have passed since the transmission of the previous detection value. If 60 minutes have passed (YES at T17), the process returns to T12 to measure air pressure and acceleration (T12) and transmit detected values (T14, T15). If 60 minutes have not passed (NO at T17), the process returns to T16.

(calibration)
Due to individual differences between the work vehicle sensor device 12 and the reference sensor device 13, the detection values of the respective sensors may differ even if the same atmospheric pressure is measured. The difference in detection values due to such individual differences has a width of about ±30 Pa, for example. Therefore, if the system is operated with such individual differences left as it is, the accuracy of detection of the position of the work vehicle 1 by the server 2 is lowered. Therefore, sensor calibration is performed at T1 in FIG. 18 and T11 in FIG. In the calibration, the working vehicle sensor device 12 and the reference sensor device 13 are arranged on the same floor (same height), and atmospheric pressure is measured simultaneously by each sensor. The detection values of each sensor are calibrated so that the detection values of each sensor indicate the same atmospheric pressure. Then, each of the work vehicle sensor device 12 and the reference sensor device 13 whose detection values have been calibrated is arranged on a predetermined floor of the building 4 .

The tablet terminal 3 outputs the usage confirmation screen 251 received from the server 2 to the display 301 .

(Action and effect of the embodiment)
In this embodiment, on the usage status confirmation screen 251, the usage status is output after being grouped by the name of the company and the name of the individual. Therefore, according to the present embodiment, it is possible to visually and clearly display which worker is using the work vehicle 1 .

In the present embodiment, the work vehicle sensor device 12 is provided on the work platform 11 of the work vehicle 1 . Therefore, even if the work vehicle 1 is not moving, if the aerial work platform 11 is raised and lowered according to the work, the acceleration sensor 1203 of the work vehicle sensor device 12 detects the acceleration of the aerial work platform 11 when the aerial work platform 11 is raised and lowered. detectable. That is, according to the present embodiment, it is possible to acquire the operating status of the work vehicle 1 even when the work vehicle 1 is not moving. If it is not necessary to detect the elevation of the work platform 11, the work vehicle sensor device 12 may be provided at a location other than the work platform 11 of the work vehicle 1, for example.

In this embodiment, the reference sensor device 13 transmits the detection value indicating the atmospheric pressure to the server 2 at a high frequency of once every five seconds. Each time the server 2 receives a detection value from the reference sensor device 13 , the server 2 updates the atmospheric pressure corresponding to each floor of the building 4 based on the atmospheric pressure indicated by the detection value received from the reference sensor device 13 . Even in the same place, atmospheric pressure fluctuates under various conditions. According to this embodiment, it is possible to update the atmospheric pressure corresponding to each floor by following changes in the atmospheric pressure at the place where the reference sensor device 13 is installed, thereby detecting the position of the work vehicle 1 with high accuracy. can be done.

In this embodiment, the work vehicle sensor device 12 transmits to the server 2 the detected value indicating the atmospheric pressure and the detected value indicating the acceleration with a low frequency of once every 60 minutes. Therefore, compared to the case where the detection values are transmitted with high frequency, the life of the battery 1204 of the work vehicle sensor device 12 can be extended, that is, the replacement frequency of the battery 1204 can be reduced. For example, if two AA batteries are used as the battery 1204, the frequency of replacement of the AA batteries can be about once a year.

In this embodiment, various sensors provided in the work vehicle 1 are packaged as a work vehicle sensor device 12 . Therefore, according to the present embodiment, by providing the work vehicle sensor device 12 in the work vehicle 1, the server 2 can acquire the operating status of the work vehicle 1 and the floor where the work vehicle 1 is arranged.

However, the sensors included in the work vehicle sensor device 12 are not limited to these, and the work vehicle sensor device 12 may include other sensors. Work vehicle sensor device 12 may further include, for example, a Global Positioning System (GPS) sensor. By providing the work vehicle sensor device 12 with a GPS sensor, the server 2 can identify the floor where the work vehicle 1 is arranged (identify the position in the height direction) by the air pressure sensor 1202, and also can detect the work vehicle 1 in the same floor. location (horizontal location) can also be performed.

In the embodiment, the reference sensor device 13 is installed on the first floor of the building 4, but the reference sensor device 13 may be installed on floors other than the first floor. In this case, the position of the reference sensor device 13 (installed floor number) may be stored in the auxiliary storage unit 203 of the server 2 .

In the embodiment, the microcomputer 1201 of the work vehicle sensor device 12 suppresses transmission of the detection value of the acceleration sensor 1203 to the server 2 when the detection value of the acceleration sensor 1203 is less than the threshold. However, the microcomputer 1201 may transmit the detection value of the acceleration sensor 1203 to the server 2 even if it is less than the threshold value. In this case, the server 2 may determine that the work vehicle 1 is not in operation when the received detection value of the acceleration sensor 1203 (or the acceleration indicated by the detection value) is less than the threshold.

The usage acceptance screen 241 may further include a time zone specification field for accepting specification of the time zone in which the work vehicle 1 is to be used. The time period may be, for example, a specific start time to end time, or a.m. or p.m. When the usage acceptance screen 241 accepts designation of the time zone, the usage status confirmation screen may also display the time zone.

A two-dimensional code may be used for acceptance of use of the work vehicle 1 . For example, a two-dimensional code including information indicating the vehicle name of the work vehicle 1 is attached to each work vehicle 1 . Then, the tablet terminal 3 may accept the use of the work vehicle 1 by photographing the two-dimensional code attached to the work vehicle 1 with the camera 303 .

In the embodiment, the work vehicle sensor device 12 and the reference sensor device 13 transmit the detection values at intervals set for each, but the timing at which the work vehicle sensor device 12 and the reference sensor device 13 transmit the detection values are set individually. are not limited to specified intervals. For example, the work vehicle sensor device 12 and the reference sensor device 13 may transmit detection values according to instructions from the tablet terminal 3 . If the battery 1204 included in the work vehicle sensor device 12 has sufficient remaining capacity, there is no problem even if the detection values are transmitted at high frequency. can be confirmed at the timing of

In the embodiment, the operating status confirmation screen 252 displays operating status icons 253 that schematically indicate the operating status of each work vehicle 1 . The operating status icon 253 allows the operating status of each work vehicle 1 to be visually grasped. By making it possible to grasp the operation status of the work vehicle 1, for example, it becomes possible to grasp the work vehicle 1 that has been registered for use but has not been in operation, and it is appropriate to prevent use registration more than necessary. It can also be used to alert workers to register for use. In addition, the operation status icon 253 may be displayed in a different color, for example, so that the user can easily recognize that it is not in operation despite being registered for use.

Although the tablet terminal 3 is used in the embodiment, the portable information processing device used by workers in the work vehicle management system 100 is not limited to the tablet terminal 3 . A portable information processing device used by a worker may be, for example, a smart phone, a mobile phone, a notebook personal computer, or a wearable terminal.
