Description

The present invention relates to a concrete pouring management system.

Patent Document 1 discloses a system for managing the concrete pouring status at a concrete pouring site. The management system in Patent Document 1 includes a host computer with a database and multiple communication devices that send data to the database and check the contents of the database. The management system in Patent Document 1 also allows ready-mixed concrete manufacturing companies, construction companies, sales companies, and others to check information on the number of concrete trucks being used for concrete pouring as needed.

Japanese Patent Application Laid-Open No. 2018-1658

However, the management system in Patent Document 1 requires on-site workers to manually confirm the number of concrete trucks being used for concrete pouring and input the delivery volume, etc. This increases labor costs and poses many problems in terms of the reliability of management and the speed of management work.
In particular, when there are multiple pouring areas at a pouring site, it becomes more complicated to check the number of concrete transport trucks and input the delivery volume, etc., so there was a demand to improve this.

The present invention aims to solve the above problems by proposing a concrete pouring management system that can reduce personnel costs, improve management reliability, and speed up management work.

To solve this problem, the present invention provides a concrete pouring management system for managing the pouring status of concrete at a concrete pouring site. The concrete pouring management system includes distance sensors installed around a concrete unloading area to measure the distance to a concrete transport vehicle and the height of the concrete transport vehicle ; a determination means for determining whether a concrete transport vehicle has entered the unloading area based on the measurements of the distance sensors; a measurement means for counting the number of concrete transport vehicles when the determination means determines that a concrete transport vehicle has entered the unloading area; and a display device capable of displaying the results measured by the measurement means. The determination means is preset with a distance threshold for determining the presence or absence of a concrete transport vehicle and a height threshold for distinguishing between the concrete transport vehicle and at least a site worker. The determination means determines that the concrete transport vehicle has entered the unloading area when the measured distance value is continuously smaller than the distance threshold value for a predetermined time and the measured height value is greater than the height threshold value.

In the present invention, the presence or absence of a concrete transport vehicle that has entered the unloading area (such as around the hopper of a concrete pump vehicle) can be automatically determined by the determination means based on the measurement values of the distance sensor. Therefore, there is no need for a site worker to wait near the unloading area and visually check and record the presence or absence of a concrete transport vehicle.
In addition, the number of concrete transport vehicles is counted by the measuring means and the results are displayed on the display device, which makes management more reliable and quicker. Furthermore, the display device allows not only on-site workers but also ready-mixed concrete manufacturers, construction companies, sales companies, etc. to conveniently share the pouring status.

It is also desirable that the measuring means be capable of measuring the amount of concrete poured.

This configuration allows you to accurately and easily grasp the progress of concrete pouring.

Furthermore, when a plurality of unloading locations are located at a concrete pouring site, it is preferable that the distance sensor, the determination means, and the measurement means are provided corresponding to each unloading location. It is also preferable that the results measured by each measurement means are collectively displayed on the display device.

By configuring it in this way, even if there are multiple areas where concrete is unloaded at a pouring site, the pouring status can be consolidated and displayed on the display device. Therefore, even at large-scale pouring sites, highly reliable management can be achieved, and management work can be carried out with great speed.

The concrete pouring management system of the present invention can reduce personnel costs, improve management reliability, and speed up management work.

FIG.

Embodiments of the present invention will be described below with reference to the drawings as appropriate. Below, we will explain a concrete pouring management system for a pouring structure (pouring site) K with multiple pouring areas A to F as shown in Figure 3, but this is not intended to limit the number of pouring areas A to F, and the system can also be applied to pouring sites with a single pouring area.

The concrete pouring management system of this embodiment counts the number of agitator trucks W, which are concrete transport vehicles, that have arrived at the multiple concrete pump trucks P1 to P6 stationed at the pouring site K, and displays the progress of pouring in each pouring area A to F on a display device 20 (see Figure 8). Each concrete pump truck P1 to P6 is equipped with a hopper H (see Figure 4) that receives concrete, and in this embodiment, hopper H is the concrete unloading location.

The concrete pouring management system includes a management and control unit 10 as shown in Figure 1. The management and control unit 10 is provided individually for each concrete pump vehicle (hereinafter referred to as each pump vehicle) P1 to P6. The management and control unit 10 may be installed in each pump vehicle P1 to P6, or may be provided separately from each pump vehicle P1 to P6. Furthermore, part of the configuration may be equipped on each pump vehicle P1 to P6. The following describes a management and control unit 10 installed on each pump vehicle P1 to P6. Note that power for the management and control unit 10 is supplied from each pump vehicle P1 to P6.

In this embodiment, pump vehicles P1 to P6 are arranged corresponding to pouring areas A to F. Information obtained by each management control unit 10 of each pump vehicle P1 to P6 is displayed on each display device 20 provided on each pump vehicle P1 to P6. Meanwhile, as shown in FIG. 2, the information obtained by each management control unit 10 is also stored on a server (not shown) on the Internet. Each management control unit 10 acquires information on other pouring areas stored on the server from the server, and consolidates and sends the information on the relevant pouring area to the display device 20. This allows each display device 20 to consolidate and display the pouring information for all pouring areas A to F (see FIG. 7).
The information for all pouring areas A to F stored on the server can be displayed via the Internet on mobile devices (display devices) such as smartphones carried by area workers, computers (display devices) in the site office, and tablets (display devices) carried by the shipping staff at the ready-mix concrete plant.
Since the management control units 10 have the same configuration, the following description will be given taking the management control unit 10 installed in the pump vehicle P1 as an example.

The management control unit 10 includes a determination means 11, a measurement means 12, and a pouring completion determination means 19. Two sensors, a left distance sensor 13 and a right distance sensor 14, are connected to the management control unit 10. A display device 20 is also connected to the management control unit 10.

The left distance sensor 13 and the right distance sensor 14 are sensors that utilize known optical means. In this embodiment, a laser is used as the light source for projection. As shown in Figures 4 and 5, the left distance sensor 13 and the right distance sensor 14 are supported by a support pillar 15 erected at the rear of the pump vehicle P1 (around the hopper H) via a hinge portion 16a and support arms 16, 16. The positions of the left distance sensor 13 and the right distance sensor 14 can be adjusted in the front-rear and left-right directions by the support arms 16, 16.
6, the left distance sensor 13 and the right distance sensor 14 can be tilted left and right and up and down (not shown) around the tip support portion 17 of the support arm 16. This allows for more accurate measurement of the distance to the agitator wheel W.

As shown in Figure 4, the left distance sensor 13 measures the distance from the left rear of the pump vehicle P1 to the agitator vehicle W approaching the hopper H. The right distance sensor 14 measures the distance from the right rear of the pump vehicle P1 to the agitator vehicle W approaching the hopper H.
The left distance sensor 13 and the right distance sensor 14 can also measure the height of the agitator vehicle W. By measuring the height, it is possible to avoid mistakenly measuring a field worker or the like approaching the hopper H of the pump vehicle P1 as the agitator vehicle W.
The measured values of the left distance sensor 13 and the right distance sensor 14 are sent to the determining means 11 of the management control unit 10 .

The determination means 11 acquires the measurement values of the left distance sensor 13 and the right distance sensor 14, and based on the measurement values, determines whether or not an agitator vehicle W has entered a predetermined position to the left rear of the hopper H of the pump vehicle P1 or to the right rear of the hopper H.
The determination means 11 is preset with a distance threshold for determining whether an agitator vehicle W is present at a predetermined position. The distance threshold is preferably set to, for example, 250 to 350 cm. In this embodiment, it is set to 300 cm. The determination means 11 also has preset a height threshold for distinguishing between an agitator vehicle W and a site worker or the like. The height threshold is set to, for example, 250 cm.

The determination means 11 then compares the distance threshold value with the measured value, and if the measured value remains smaller than the distance threshold value for a predetermined time, and compares the height measurement value with a height threshold value, and if the height measurement value is greater than the height threshold value, determines that the agitator vehicle W has entered a predetermined position behind the hopper H. This determination is made independently for each of the left distance sensor 13 and the right distance sensor 14. In other words, the determination means 11 can individually determine that the agitator vehicle W has entered the left rear or right rear of the hopper H. The predetermined time is set to, for example, 10 seconds.
When the determining means 11 determines that the agitator vehicle W has entered the rear of the hopper H, it sends the determination result to the measuring means 12.

On the other hand, the determining means 11 compares the distance threshold value with the measured value, and determines that the agitator vehicle W is not located behind the hopper H if the measured value is greater than the distance threshold value.
The determination means 11 may be configured to set a threshold value for standby determination that is greater than the distance threshold value, and to detect that the agitator vehicle W is waiting at a predetermined standby position behind the hopper H. This configuration makes pouring management clearer.

Furthermore, after determining that the agitator vehicle W has entered the rear of the hopper H, the determination means 11 determines that the agitator vehicle W has left the rear of the hopper H if the measurement value becomes greater than the distance threshold value.

When the determining means 11 determines that an agitator vehicle W has entered the rear of the hopper H, the measuring means 12 receives the determination result and counts (integrates) the number of agitator vehicles W.
The measuring means 12 also calculates the amount of concrete poured based on the count value of the number of agitator vehicles W. The volume of ready-mixed concrete per agitator vehicle W can be changed by inputting information on the display device 20 side.

The measuring means 12 sends information on the number of agitator vehicles W that have been counted and information on the accumulated amount of concrete poured to the display device 20.
Meanwhile, the measuring means 12 transmits the information to a server on the Internet via a communication device (not shown) provided in the management control unit 10. As a result, information corresponding to the pump vehicle P1 is stored in the server on the Internet. Similarly, information relating to the other pouring areas B to F is also stored in the server on the Internet.

The management control unit 10 acquires information about other casting areas B to F stored on a server on the Internet via a communication device (not shown), consolidates the acquired information, and sends it to the display device 20.

The concrete pouring completion determination means 19 determines whether pouring has completed in the concrete pouring area A. Specifically, the concrete pouring completion determination means 19 determines that pouring has completed when the number of pump trucks P1 counted by the measurement means 12 reaches the predetermined planned number of pump trucks to be poured in the concrete pouring area A.

The display device 20 has a display screen as shown in Figure 7. The display screen displays information on each of the pouring areas A to F, as well as other information, in an aggregated form. The display screen has three display regions R1 to R3. Each piece of information is displayed in a simplified format on the display screen.
Display area R1 on the left side of the display screen is a main area that displays information related to the pouring area A of the pump vehicle P1. Information on the number of agitator vehicles W and information on the pouring amount of concrete input from the measurement means 12 is displayed in display area R1. Specifically, the pouring area "Area A" is displayed in the frame indicated by reference numeral 21a in the figure, and the current number of agitator vehicles W and the positions where the agitator vehicles W have entered are displayed in the frame indicated by reference numeral 21b. In this case, if a triangle mark is displayed to the left of the number of vehicles, it indicates that an agitator vehicle W is located to the left of the hopper H, and if a triangle mark is displayed on the right, it indicates that an agitator vehicle W has entered the right of the hopper H.

The box indicated by reference symbol 21c in the figure displays the total pouring volume, which is the cumulative total amount of concrete poured, and the box indicated by reference symbol 21d displays the progress of pouring. Furthermore, the box indicated by reference symbol 21e in the figure displays the volume of ready-mixed concrete in the agitator truck W. This volume is a pre-registered default value, but can be changed manually each time. The total pouring volume is calculated based on the volume of ready-mixed concrete in the agitator truck W. Furthermore, the box indicated by reference symbol 21f in the figure displays the number of concrete pours planned for Area A.

The display area R2 on the right side of the display screen is a sub-area that displays the progress of the entire area and information about the concrete pouring areas B to F other than the concrete pouring area A. The information about the other concrete pouring areas B to F is obtained from a server on the Internet via the communication device of the management control unit 10.
Specifically, the progress of the entire area is displayed in the frame indicated by reference numeral 22a in the figure, and the number of agitator vehicles W, the positions of the agitator vehicles W, and the progress of the concrete pouring areas B to F are displayed in the frame indicated by reference numeral 22b in the figure.

A display area R3 at the bottom of the display screen is an area for displaying other information and settings.
Specifically, the concrete pouring history for three vehicles in Area A is displayed within the frame indicated by reference numeral 23a in the figure. The information displayed includes the position of the agitator vehicle W, the volume of ready-mixed concrete, the IN time (arrival time of the agitator vehicle W), the OUT time (departure time of the agitator vehicle W), the elapsed time since pouring, and a delete button. The IN time is the time when the determination means 11 of the management control unit 10 determines that the agitator vehicle W has entered the rear of the hopper H. The OUT time is the time when the determination means 11 determines that the agitator vehicle W has departed.
If the volume of ready-mixed concrete is changed, it can be changed by touching the volume field in the frame 23a. The changed information is reflected in the information on the cumulative pouring volume.

Other information is displayed within the frame indicated by reference symbol 23b in the display area R3. Subframe 24a within frame 23b displays the measured distance of the left distance sensor 13 and right distance sensor 14, the detected distance (threshold distance), the number of seconds elapsed (elapsed time), and the number of seconds detected (predetermined time: threshold of the elapsed time at which the detected distance is reached). Subframe 24b also displays the date and time and the elapsed time since the start of pouring. Subframe 24c is an operation field for acquiring information; a touch operation will start acquiring information for the entire area. It can also be set to update information in real time. Subframe 24c displays the communication status (radio wave strength) of the communication device.

Next, the operation control process of the concrete pouring management system of this embodiment will be described.
8A and 8B are flowcharts showing the operation control process.
8A, when the operation control process is started, various settings are input in step ST1. In step ST1, the management control unit 10 receives input of various settings related to pouring management, such as data on the detection distance (threshold distance) stored in advance in a memory unit (not shown), data on the number of seconds for detection (predetermined time), data on the height of the agitator vehicle W, data on the volume of ready-mixed concrete in the agitator vehicle W, and data on the number of vehicles planned to be poured.

In step ST2, the left distance sensor 13 and the right distance sensor 14 start measuring the distances to the left rear and right rear of the pump vehicle P1. The following steps ST3 to ST12 are operation control processes based on the measurement value of the left distance sensor 13.
In step ST3, the determination means 11 of the management and control unit 10 compares the measurement value of the left distance sensor 13 with the distance threshold and determines whether the measurement value of the left distance sensor 13 is smaller than the distance threshold. If the measurement value of the left distance sensor 13 is larger than the distance threshold, that is, if the agitator vehicle is not in the predetermined position to the left rear of the hopper H (if there is nothing within the distance threshold), the determination result in step ST3 is No, and the process proceeds to step ST9. In step ST9, the determination means 11 determines the state of the left rear based on the presence or absence of a flag. In this case, the determination means 11 determines whether the state of the left rear is a "non-detection" state with no flag set, a "provisional detection" flag set, or a "detection" flag set (detection in progress). In this case, the state is determined to be a "non-detection" state with no flag set, and the process proceeds to step ST13 (see FIG. 8B).

On the other hand, if the measurement value of the left distance sensor 13 is smaller than the distance threshold in step ST3, i.e., if the agitator vehicle W has entered a predetermined position to the left rear of the pump vehicle P1, step ST3 is judged as Yes and the process proceeds to step ST4.

In step ST4, the determination means 11 determines the state of the left rear. In this case, the determination means 11 determines whether the state of the left rear is the initial "non-detection" state, the "provisional detection" state before it is confirmed that the agitator wheel W has entered, or the "detection" state after it is confirmed that the agitator wheel W has entered. In this case, since it is the first time that the agitator wheel W has been detected as having entered, it is determined to be in the "non-detection" state, and the process proceeds to step ST5. In step ST5, the determination means 11 sets a "provisional detection" flag for the left rear state, starts counting the detection time of "provisional detection," and proceeds to step ST13. The process then proceeds to step ST2 via steps ST13 to ST27, which will be described later, and repeats the following steps.

If this repetition returns a Yes in step ST3, the process proceeds to step ST4, where it is determined that the state is a "tentative detection," and the process proceeds to step ST6. In step ST6, the determination means 11 starts counting the detection time for "tentative detection" and determines whether the detection time has exceeded a preset number of seconds. If the detection time has not exceeded the preset number of seconds, the process returns No in step ST6 and the process proceeds to step ST13. The process then proceeds to step ST2 via steps ST13 to ST27, described below, and the process is repeated. On the other hand, if the detection time has exceeded the preset number of seconds in step ST6, the process returns Yes in step ST6 and the process proceeds to step ST7.

In step ST7, the determination means 11 determines that the agitator vehicle W has entered the left rear of the hopper H, i.e., that ready-mixed concrete can be poured into the hopper H of the pump vehicle P1, and sets a "detection" flag. The time when the "detection" flag is set becomes the "IN time" of the agitator vehicle W.

In step ST8, the measurement means 12 counts (accumulates) the number of agitator vehicles W.

On the other hand, if the "provisional detection" flag is set and the repeated step ST3 returns No, the process proceeds to step ST9, where it is determined that the "provisional detection" flag was set, and the process proceeds to step ST10. In step ST10, the determination means 11 cancels the "provisional detection" flag for the left rear state and changes the left rear state to a "non-detection" state. This prevents vehicles and agitator vehicles W that temporarily come within the left rear distance threshold from being counted.

Furthermore, if the "detection" flag is set and the repeated step ST3 returns No, the process proceeds to step ST9, where it is determined that the "detection" flag was set, and the process proceeds to step ST11. In step ST11, the determination means 11 starts counting the "non-detection" detection time and determines whether the detection time has exceeded a preset number of seconds. If the detection time has not exceeded the preset number of seconds, the process returns No in step ST11 and proceeds to step ST13. The process then proceeds to step ST2 via steps ST13 to ST27, which will be described later, and the following steps are repeated. On the other hand, if the detection time has exceeded the preset number of seconds in step ST11, the process returns Yes in step ST11 and proceeds to step ST12.

In step ST12, the determination means 11 determines that the agitator vehicle W has left the left rear of the hopper H, cancels the "detected" flag, and changes the state of the left rear to "not detected." The time when the "detected" flag is canceled becomes the "OUT time" of the agitator vehicle W.

Next, the operation control process based on the measurement value of the right distance sensor 14 will be described with reference to steps ST13 to ST22 shown in Fig. 8B. The operation control process related to the right distance sensor 14 is similar to steps ST3 to ST12 of the operation control process based on the measurement value of the left distance sensor 13 described above.
That is, in step ST13, the determination means 11 compares the measurement value of the right distance sensor 14 with the distance threshold value and determines whether the measurement value of the right distance sensor 14 is smaller than the distance threshold value. If the measurement value of the right distance sensor 14 is larger than the distance threshold value, that is, if the agitator vehicle is not in the predetermined position to the right rear of the hopper H (if there is nothing within the distance threshold value), the determination result in step ST13 is No, and the process proceeds to step ST19. In step ST19, the determination means 11 determines the state of the right rear based on the presence or absence of a flag. In this case, the determination means 11 determines whether the state of the right rear is a "non-detection" state with no flag set, a "provisional detection" flag set, or a "detection" flag set (detection in progress). In this case, the state is determined to be a "non-detection" state with no flag set, and the process proceeds to step ST23.

On the other hand, if the measurement value of the right distance sensor 14 is smaller than the distance threshold in step ST13, i.e., if the agitator vehicle W has entered a predetermined position to the right rear of the pump vehicle P1, step ST13 is judged as Yes and the process proceeds to step ST14.

In step ST14, the determination means 11 determines the state of the right rear. In this case, the determination means 11 determines whether the state of the right rear is the initial "non-detection" state, the "provisional detection" state before it is confirmed that the agitator wheel W has entered, or the "detection" state after it is confirmed that the agitator wheel W has entered. In this case, since it is the first time that the agitator wheel W has been detected as having entered, it is determined to be in the "non-detection" state, and the process proceeds to step ST15. In step ST15, the determination means 11 sets a "provisional detection" flag for the right rear state, starts counting the detection time of "provisional detection," and proceeds to step ST23. The process then proceeds to step ST2 via steps ST23 to ST27, which will be described later, and repeats the following steps.

If this repetition returns a Yes in step ST13, the process proceeds to step ST14, where it is determined that the state is a "tentative detection," and the process proceeds to step ST16. In step ST16, the determination means 11 starts counting the detection time for "tentative detection" and determines whether the detection time has exceeded a preset number of seconds. If the detection time has not exceeded the preset number of seconds, the process returns No in step ST16 and the process proceeds to step ST23. The process then proceeds to step ST2 via steps ST23 to ST27, described below, and the process is repeated. On the other hand, if the detection time has exceeded the preset number of seconds in step ST16, the process returns Yes in step ST16 and the process proceeds to step ST17.

In step ST17, the determination means 11 determines that the agitator vehicle W has entered the rear right of the hopper H, i.e., that ready-mixed concrete can be poured into the hopper H of the pump vehicle P1, and sets the "detected" flag.

In step ST18, the measurement means 12 counts (accumulates) the number of agitator vehicles W.

On the other hand, if the "provisional detection" flag is set for the right rear state and then the repeated step ST13 returns No, the process proceeds to step ST19, where it is determined that the "provisional detection" flag was set, and the process proceeds to step ST20. In step ST20, the determination means 11 cancels the "provisional detection" flag for the right rear state and changes the right rear state to a "non-detection" state. This prevents vehicles and agitator vehicles W that temporarily come within the right rear distance threshold from being counted.

Furthermore, if the "detection" flag is set for the right rear state and the repeated step ST13 returns No, the process proceeds to step ST19, where it is determined that the "detection" flag was set, and the process proceeds to step ST21. In step ST21, the determination means 11 starts counting the "non-detection" detection time and determines whether the detection time has exceeded a preset number of seconds. If the detection time has not exceeded the preset number of seconds, the process returns No in step ST21 and proceeds to step ST23. The process then proceeds to step ST2 via steps ST23 to ST27, described below, and the following steps are repeated. On the other hand, if the detection time has exceeded the preset number of seconds in step ST21, the process returns Yes in step ST21 and proceeds to step ST22.

In step ST22, the determination means 11 determines that the agitator vehicle W has left the right rear of the hopper H, cancels the "detected" flag, and changes the state of the right rear to "not detected."

Next, the operation control process after determining the left rear and right rear states will be described with reference to steps ST23 to ST27.
In step ST23, the measuring means 12 calculates the cumulative pouring amount based on the data on the volume of ready-mixed concrete in the agitator vehicle W input in step ST1. In this case, the cumulative pouring amount is calculated only when the "detection" flag is set, and is not calculated when the "non-detection" state or the "provisional detection" flag is set.

Then, in step ST24, the measurement means 12 calculates the concrete pouring progress based on the planned number of concrete pouring vehicles input in step ST1 and the cumulative number of agitator vehicles W calculated in steps ST8 and ST18. In this case, too, the concrete pouring progress is calculated only when the "detection" flag is set; the concrete pouring progress is not calculated when the "non-detection" state or the "provisional detection" flag is set.

In step ST25, the management control unit 10 sends information on the number of agitator vehicles W counted by the measuring means 12, information on the accumulated pouring volume calculated by the measuring means 12, and information on the progress of pouring to the display device 20. The management control unit 10 also receives information on other pouring areas B to F from a server on the Internet via a communication device (not shown), consolidates this information, and sends it to the display device 20.

Then, in step ST26, the display device 20 consolidates the received information about pouring area A and the other pouring areas B to F and displays them on the display screen. In this case, information about pouring area A is displayed in display area R1 on the display screen, and the progress of the entire area and information about pouring areas B to F are displayed in display area R2. In addition, other information and settings are displayed in display area R3.

In step ST27, the pouring completion determination means 19 compares the number of agitator vehicles W counted by the measurement means 12 with the number of vehicles planned to be poured entered in step ST1, and determines whether the number of agitator vehicles W is equal to or greater than the number of vehicles planned to be poured. If the number of agitator vehicles W is smaller than the number of vehicles planned to be poured, i.e., if the number of agitator vehicles W is less than the number of vehicles planned to be poured, step ST27 is determined to be No and the process proceeds to step ST2. Then, step ST3 is repeated. On the other hand, if the number of agitator vehicles W is equal to or greater than the number of vehicles planned to be poured, i.e., if the number of agitator vehicles W has reached the number of vehicles planned to be poured, step ST27 is determined to be Yes and the process ends. Information on the completion of processing in pouring area A is stored and shared on a server on the Internet via the communication device of the management control unit 10.

With the concrete pouring management system of this embodiment described above, the determination means 11 can automatically determine whether an agitator vehicle W has entered the rear of the hopper H of pump vehicles P1 to P6 based on the measurements of the left distance sensor 13 and the right distance sensor 14. Therefore, there is no need for on-site workers to wait near pump vehicles P1 to P6 and visually check and record the presence or absence of an agitator vehicle W.

In addition, the measuring means 12 counts (adds up) the number of agitator vehicles W, and the results are displayed on the display device 20, resulting in highly reliable management and quick management work. Furthermore, the display device 20 allows on-site workers, as well as ready-mixed concrete manufacturers, construction companies, sales companies, etc., to conveniently share the pouring status. This allows ready-mixed concrete manufacturers to efficiently ship ready-mixed concrete, enabling concrete to be poured without interruption. It is also easy to order additional quantities to make up for any shortfalls, reducing the amount of surplus ready-mixed concrete.

In addition, since the measuring means 12 can measure the amount of concrete poured, the progress (progress status) of pouring can be accurately and easily grasped.

Furthermore, even if there are multiple areas where concrete is poured at a pouring site, the pouring status can be consolidated and displayed on the display device 20. Therefore, even at large-scale pouring sites, highly reliable management can be achieved, and management work can be performed quickly.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and each component can be appropriately modified within the scope of the invention.
For example, in the above embodiment, the left distance sensor 13 and the right distance sensor 14 are provided on each of the pump vehicles P1 to P6, but this is not limiting and they may be arranged using stands 18, 18 as shown in Fig. 9. In this case as well, the distance to the agitator vehicle W can be suitably measured.

Furthermore, the left distance sensor 13 and the right distance sensor 14 use lasers as the light source for projection, but this is not limited to this and other optical means may be used. Also, a single distance sensor may be provided.

Furthermore, the determination means 11 does not necessarily have to have a height threshold, and may determine that the agitator vehicle W has entered the unloading area based solely on a distance threshold.

The layout of display areas R1 to R3 shown in the embodiment is merely an example and can be modified as appropriate. The display items can also be selected as appropriate.

Furthermore, in the above embodiment, multiple pump vehicles P1 to P6 are deployed, but this is not limited to this and the system can also be applied to a concrete pouring site where only one pump vehicle P1 is deployed.

In addition, in the above embodiment, an agitator vehicle W was used as an example of a concrete transport vehicle, but this is not limited to this, and a transport vehicle using a bucket may also be configured to measure distance using a distance sensor.
