Moreover, in the present invention, the monitoring device 10 does not necessarily transmit both the entry time and the exit time. For example, in a site where a plurality of transportation vehicles A1 continuously perform construction work, there is no problem even if only the entry time of each transportation vehicle A1 is recorded.

<2.2> Operation time of pump car (Fig. 2(b))
The start time and end time of the operation of the distribution board A21 for the pump provided in the pump car A2 for pumping concrete are regarded as the start and end time of placing the concrete C, and stored as the operation record D2 in the management terminal 30. It is a method to keep

For example, when a GPS 11 device attached to the transport vehicle A1 is used as the monitoring device 10, identification information of the transport vehicle A1 can be included in the information transmitted to the monitoring terminal.
Further, if the monitoring device 10 is a code reader prepared at the work site, the two-dimensional code attached to the transport vehicle A1 is read manually or automatically by a code reader or the like, and the information transmitted to the monitoring terminal is can include the identification information of the transport vehicle A1.
In addition, when the monitoring device 10 is configured by the gate sensor 12 or the like, even if the entrance and exit of the transportation vehicle A1 can be detected, the transportation vehicle A1 may not be identified. In this case, from other process management data such as a work plan table, the corresponding transportation vehicle A1 may be separately linked by the management terminal 30, which will be described later.

These are sent to the management terminal 30 by wireless communication or the like.

<3.1> Filling sensor (Fig. 1, Fig. 3)
The filling sensor 21 is a sensor for detecting whether or not concrete C is placed at the installation location of the sensor.
This detection information is sent to the management terminal 30 in real time or at predetermined time intervals.
As shown in FIG. 3, in the management terminal 30, based on the detection information sent from the filling sensor 21, a filling record E is generated in which the presence or absence of filling of the concrete C for each filling sensor 21 is recorded in units of time. .
By referring to this filling record E, the user can check the filling status of the concrete C in real time.

<3.2> Temperature sensor (not shown)
The temperature sensor is a sensor for measuring the temperature at the location where the sensor is installed, and by extension, the surface temperature of the placed concrete C.
By referring to this measured temperature, it is possible to manage the demolding strength of the concrete C after it has been placed, and it is possible to realize appropriate curing management.

<3.3> Pressure sensor (not shown)
A pressure sensor is a sensor for measuring the pressure received by the concrete C at the installation location of the sensor.

For example, if the monitoring device 10 acquires the identification number of the transportation vehicle A1 and the start time and end time of placing, the concrete C in the area filled by the filling sensor 21 within this time is detected by the transportation vehicle. It can be determined that it is the concrete C transported by A1.

<4.1.1> Matching Image FIG. 4 shows a matching image diagram of the concrete C mounted on the transport vehicle A1 and the placed concrete C. As shown in FIG.
In FIG. 4, the entrance/exit record D1 records the entrance time of the delivery vehicle A1 (NO.1) as 10:00 and the exit time as 10:30.
In the filling record EE, none of the filling sensors 21 indicate that the concrete C is filled at the stage of 10:00, and at the stage of 10:10, the filling sensor 21 (A-1) indicates that the concrete C is filled. It is recorded that it was filled.
Therefore, at the position where the filling sensor 21 (A-1) is provided, NO. It can be collated that the concrete C mounted on the 1 transportation vehicle A1 was used.

The transition (placement progress) of the setting completion area is illustrated like a so-called contour line display.
According to this contour diagram 70, the transition of the placement completion area of the concrete C can be easily visually recognized.

<4.4> Placement information display means (Fig. 1, Fig. 7)
The placement information display means 34 is a function that displays other placement information obtained from the in-form sensor 20 in a manner that can be confirmed by the user terminal 40 .
FIG. 7 shows an image diagram of a state in which a contour drawing 70 and other placing information are layer-displayed on the placing site drawing 60 at an intermediate stage of the placing work.
Since the contour drawing 70 is the same as the description relating to FIG. 6, detailed description thereof will be omitted. A bold line surrounding the contour diagram 70 is an inflow line 72 indicating the boundary of the filling position of the concrete C at the present stage.
In this embodiment, as the placement information, the measured values themselves (temperature value 81 and pressure value 82) by the temperature sensor and the pressure sensor, the separately calculated strength value 83 of the concrete C, and the coloring are changed according to these values. It contains configured blocks (temperature display block 91, pressure display block 92, intensity display block 93).
By confirming these placement information on the placement site drawing 60, it becomes easier to determine appropriate curing of the concrete C and grasp of the concrete C load related to the formwork B, and the quality control of the concrete C is further improved. It can be easily realized.

Next, a second embodiment of the invention will be described.
In the above-described first embodiment, as a method for detecting the usage status of concrete, the position of the transport vehicle on which concrete is loaded and the operation status of the distribution board of the pump for pumping the concrete are detected. However, the present invention is not limited to the above embodiments.
For example, the usage of concrete in the bucket may be detected by detecting the position of the concrete bucket used for placing the concrete.
Further, a sensor for detecting the passage of concrete may be provided on the way of a pipe for sending concrete or a flow path such as a hopper to detect the use condition of concrete in the pipe.

Next, a third embodiment of the invention will be described.
In the present invention, the measurement data obtained from other measuring devices in the process of placing concrete may be further associated with the usage and filling conditions of the concrete described above.
For example, if a concrete quality control measuring device (such as an RI moisture meter) is installed in the concrete delivery pipe described in the second embodiment, the measurement data obtained from these measuring devices can be managed. The quality control data of the concrete used in a specific area of the casting area can be easily grasped by acquiring the data with the device and linking it with the usage status and filling status of the concrete described above.
