Each of the plurality of IC tag detection areas 201 and 202 includes a radio station 203 connected to the hub device 220 and a radio station antenna 204 that detects the IC tags 81 and 82. Here, the IC tag detection area 201 detects the IC tag 81 mounted on the truck 91 that transports concrete from the BP2. The IC detection area 202 detects an IC tag 82 mounted on a bucket 92 of a crane that transports concrete to the GH 4. The wireless communication unit 210 includes a wireless AP 211 and a wireless AP antenna 212 that are connected to the hub device 220, and wirelessly connects between the hub device 220 and other bases (BP2 and GH4) other than CH3.

The wireless communication unit 360 includes a wireless AP 361 and a wireless AP antenna 212 connected to the hub device 370, and wirelessly connects between the hub device 370 and other bases (BP2 and CH3) other than the GH4. The IC tag detection area 201 includes a wireless station 351 connected to the hub device 220 and a wireless station antenna 352 that detects the IC tag 82 mounted on the bucket 92 that transports concrete from CH3.

The placement site display unit 380 includes a wireless AP 381 and a wireless AP antenna 382 that are connected to the hub device 370, and further includes a display panel 383 that is wirelessly connected to the wireless AP antenna 382. The display panel 383 is a large display panel with LED display installed in a place with a good view from the installation site (for example, within a maximum of 80 m), and is a wireless communication means (FIG. 3) for wireless connection with the wireless AP antenna 382. Not shown). The display panel 383 receives information on the quality of the concrete that has been received and managed by shipment and is properly transported (mixing type, mixing completion time), or information that has been transported and the concrete that has been transported. An error is displayed if an administrative failure occurs.
Thereby, it is possible to confirm the quality of the concrete (determined by the blending type and the elapsed time from the kneading manufacture) shipped at the time of placing and perform the placing.

  The hub devices 130, 220, and 370 to which the wireless stations 141, 203, and 351 and the wireless APs 151, 211, 361, and 381 are connected are PoE power supply switching hub devices (hubs) having a power supply function using PoE (Power over Ethernet). (Shown as a device).

  In the illustrated example, each of BP2, CH3, and GH4 is provided with one IC tag detection area (one lane) for detecting an IC tag mounted on the truck 91 and the bucket 92. May be installed. The track 91 and the bucket 92 on which the IC tag is mounted can be used in a plurality of lanes, and the track 91 can be used in and out of any lane of the plurality of lanes. In addition, the number of the trucks 91 and the buckets 92 is not limited to one, and a plurality of trucks 91 and buckets 92 may be provided.

Next, wireless communication used in this system will be described. The wireless communication used in this system includes IC tag communication (first communication means) for detecting the IC tags 81 and 82 by each hopper (BP2, CH3, GH4) and wireless communication between the hoppers. Wireless AP communication (second communication means) to be connected.
For the first communication means, a non-contact type IC tag and a radio station antenna are used with the electric field strength at a distance desired as a detection range as a threshold, and for communication between hoppers as a backbone to the second communication means. Wireless communication using a wireless AP and a wireless AP antenna is used.

  The first communication means is composed of, for example, a communication device of 2.4 GHz band (applied to IEEE: Institute of Electrical and Electron Engineers (802.11b)), and the radio wave arrival time difference between messages transmitted and received between the radio station and the tag. So, the time difference of arrival (TDOA) method, which calculates the distance between IC tags from a radio station and detects the position of the IC tag, and the shipment of concrete simultaneously in multiple transport lanes Considering the case, it is desirable to adopt a configuration using a received signal strength indicator (RSSI) based on the detected signal strength of the detected IC tag. When an IC tag detection area is installed in each of a plurality of transport lanes, an electric field strength at a distance to be set as a detection range is set as a threshold for each wireless station, and the IC tag is attached to the wireless station antenna. Since the electric field strength of the IC tag becomes stronger as the distance is closer, if the electrolytic strength is higher than that (with the electric field strength at the distance desired as the detection range as a threshold), the IC tag is judged to exist within the detection range. By detecting this, it becomes possible to simultaneously detect and operate IC tags in a plurality of transportation lanes.

  Next, the second communication means is composed of, for example, a communication device in the 2.4 GHz band (compliant with IEEE802.11b / g or IEEE802.11n), and relays between radio stations in each hopper, thereby shipping management device Wireless communication is performed up to 110. Since it is known in advance that the wireless AP 361 (including the wireless AP antenna 362) is moved or moved during the construction period of the dam construction, the installation position of the second communication means is stable in any state during the construction period. Wireless communication with each hopper is required. Specifically, elevation of elevation (water storage level) caused by the relocation and expansion of cranes (including buckets) and the progress of concrete placement in the dam body, the operation of multiple GH4 units, the right bank of the GH4 body And the left bank move up.

  In the wireless communication between the hoppers by the second communication means, the wireless device is appropriately adjusted by installing the antenna in a place where the antennas connected to the wireless AP can see each other. For example, at the beginning of the dam construction, it started with the installation of a bank wall at the bottom of the valley exceeding 250m as the difference in elevation (water storage level) at the time of completion, and it was operated while moving to the right and left banks of the bank (GH4) By performing adjustment and maintenance in response to changes in the operating environment, such as installing a wireless communication device including a wireless AP antenna at a position where communication can be performed, the operation can be continued favorably using the original device.

  In this embodiment, the second communication means is provided with detection technology based on the received signal strength method (RSSI), so that the transportation means can be made into a plurality of lanes, a plurality of IC tags, and a transportation means (IC tag) between lanes. Even in the event of a change or reversal (overtaking) of the transportation sequence, the number and position of the IC tag mounted on the transportation means can be identified and associated with the shipping management information, thus managing the shipment and transportation of concrete. Can be performed satisfactorily.

  In this embodiment, when concrete is sequentially transported from BP2 to CH3 through GH4 by a plurality of transport means, the presence of the IC tag is monitored over time by each hopper, and the truck on which the IC tag is mounted. Alternatively, by detecting in which lane the bucket is present, it is possible to manage the shipment of the concrete by associating the trajectory of the conveying means accompanied with the IC tag with the concrete placement information set in advance.

In addition, the operation display device 120 installed in the plant operation room 1 includes, for example, a triple (red / orange / green) lamp, and displays three operation states. The green lamp is turned on for notification when the normal connection is confirmed by the wireless communication communication confirmation at the initial setting or when the system is in a normal operation state. The red lamp is turned on for warning in a state where a disconnection is detected by communication confirmation at the time of initial setting or a communication failure has occurred. In addition, after the initial setting is completed (after the green lamp is lit), the orange lamp performs a process for checking the battery capacity of each IC tag that has been enabled and has a smaller capacity than the preset threshold (for example, The IC tag in a state where it is determined that the battery capacity is received from the IC tag and the remaining amount is 10% or less of the threshold value is in operation, and blinking (orange lamp) to notify the battery replacement To do.
The operation display device 120 is a display function that enables an administrator or the like in the plant operation room 1 to visually monitor the operation state of the system. When the lamp of the operation display device 120 is lit or blinks, the shipment management is performed. By confirming the detailed operation state with the display unit 115 of the apparatus 110, it is possible to easily identify whether the system is normal or faulty without a specialized operator.

Next, the functional configuration of the shipment management apparatus 110 will be described with reference to FIG.
In the shipping management apparatus 110, a setting information DB 301, an output log information DB 302, and a blending table 303 are formed in the DB 112. (The configuration of each DB and tables 301 to 303 will be described later with reference to FIGS. 3 to 5). Further, the control processing unit 330 includes an IC tag communication control unit 331, a shipment management control unit 332, a log output unit 333, a display control unit 334, and a combination information processing unit 335. These various functions are realized by the CPU 111 executing an application program unique to the present invention. Although not shown, a timer is provided to manage BP2, CH3, and GH4 in a uniform time. For example, the time of IC tag information detected at these bases is processed as time information for shipping management at each base using this timer.

The IC tag communication control unit 331 converts the IC tag information detected by the radio station antennas 142, 204, and 352 in the IC tag detection areas 140, 201, 202, and 350 of each hopper (BP2, CH3, GH4) into the hub device. Wireless AP antennas 152, 212, 362 are connected by wireless communication from wireless APs 151, 211, 362 via 130, 220, 370, received via hub device 130, and acquired via LAN / IF 113.
The shipment management control unit 332 mixes and finishes mixing of each concrete (mixing type), IC tag number, and position information where the tag is detected (information of IC tag detection location such as BP, CH, GH). , Based on these information, associating information from the mixing time of CH3, the arrival time of levee body to GH4, etc. Create a log. This information is appropriately managed as evidence of concrete quality in dam construction, and it is also possible to trace (trace) the shipment status of concrete later using this information.

The blending information processing unit 335 transfers the placement start information and placement end information for each placement unit received as the message type from the plant control apparatus 100, and each batch No (# 1 to #n concrete kneading times). Then, the blending information (including the blending type) managed in the shipping unit is transferred to the shipping management control unit 332.
The display control unit 334 performs display control on the operation display device 120 installed in the plant operation room 1 and the display panel 383 installed in the GH 4.

Next, each DB and table configuration will be described.
FIG. 3 shows the configuration of the setting information DB 301.
The setting information DB 301 stores information read for setting various conditions when an application program is started by the CPU 111. That is, the setting information DB 301 includes the manufacturer name of the operation panel of the plant control apparatus 100, the tag ID # associated with the IC tag number for each IC tag, and a plurality of wireless stations (141, 203, 351 in FIGS. 1A and 1B). ) Each RSSI threshold, coordinate range, definition area ID, etc., BP, CH, GH IC tag authentication count, tag battery information, log storage location information, IP address of equipment installed in radio station, display panel It consists of information such as IP address and password for input screen.

FIG. 4 shows the configuration of the output log information DB 302.
The output log information DB 302 stores all message information and placement amount logs that lead to placement start, composition information, and placement end, with a log type (log ID). A log type is assigned to each placement amount log (# 1 to #n), and blending information including a blending number (blending number) is stored. Each shipping unit log (for one truck) is assigned a log type, such as track tag ID #, (CH) passage time, bucket tag ID #, (GH) arrival time, mixing end time, etc. Trace information is stored together with the combination type (composition number).

FIG. 5 shows the configuration of the blending table 303.
The blending table 303 is composed of a blending number (mixing No.) indicating blending information of concrete and a blending type in which ranges of blending numbers are grouped. By indexing the blending table 303, the blending type is obtained from the group of the blending number range. For example, the combination number of 1101 to 1109 is “A1”. This combination type “A1” is displayed on the display panel 383 (see FIG. 13 for the display location).

FIG. 6 shows the configuration of message information 102 for each placing unit issued from the plant control apparatus.
The types of message information 102 include type A: placement start, type B (# 1 to #n): combination information, type C: placement end. The message type of the message information (starting start and end) is the start and end (date, time, altitude (water storage level): embankment height by dam placement, placement block name) information. The blending information includes batch No. (each kneading, blending No., placement amount [m ³ ] (= rice)) information. Of the blending information, the blending number is displayed on the display panel 383, for example, blending The number 1011 to 1109 is converted to the formulation type “A1”.

When the shipping management apparatus 110 is activated, the system enters a standby state for starting operation of the system.
The IC tag information detected by the first communication unit is collected in the shipping management apparatus 110 via the second communication unit. In this embodiment, each time an IC tag is detected, information on the battery capacity for driving the IC tag is also collected as IC tag information in addition to the tag number. The shipment management control unit 332 of the shipment management apparatus 110 monitors the battery capacity, and causes the display control unit 334 to blink the orange lamp of the operation display apparatus 120 when detecting a decrease in the battery capacity. This prompts replacement of the IC tag battery. In addition, the battery capacity of the IC tag acquired from the IC tag information is compared with a predetermined threshold value, and as a result, the remaining battery capacity is one of the IC tag operation information, and the tag operation over time is displayed on the screen of the display 115. It is displayed as information (FIG. 11B).

A series of processing operations of concrete shipment management in this system will be described later, but after the system is started, from the plant control device 100, “starting placement, finishing placement” is received in the placement unit as a message type, “Composition information” to be shipped is received for each shipping unit. When a placement start message for a placement unit is received first, the log output unit 333 stores the log in the placement start log of the output log information DB 302.
The blending information is received in batches (kneading) from one to several times. Each time it is received, the blending information processing unit 335 refers to the blending table 303 and converts from blending number to blending type. Is done. Here, the converted blending type is associated with the IC tag number mounted on the truck, which is one of the transportation means, so that the blended concrete information shipped and the IC tag number of the truck are associated with each other. Managed.

At CH3, which is the next concrete transport destination, the IC tag detection areas 201 and 202 monitor the arrival of the IC tag 81 of the truck 91 and the IC tag 82 of the crane bucket 92 resulting from GH4 over time. As information transmission in shipping management, information on IC tags mounted on the truck and bucket is transferred from the truck to the bucket in association with the combination type. At this time, the concrete is transferred (relayed) from the truck to the bucket.
In this way, each hopper monitors and detects the position of the IC tag over time, so that the shipping start time, CH3 passage time, and GH4 arrival time are detected each time the IC tag is detected in the IC tag detection area. It is acquired in real time and associated with the formulation information (message type B in FIG. 6). The shipment start time means the acquisition of the time when it is determined that the IC tag associated with BP2 has not been detected and shipped from BP2, and the CH3 passage time is the arrival of the truck loaded with the IC tag on CH3. In the case of multiple lanes, when the designated lane is detected from the presence position of this IC tag and is transferred to the bucket of the crane as the next transport means, it is further associated with the IC tag mounted on the bucket, It means acquisition of the time when it is determined that the IC tag further associated with CH3 has not been detected and shipped from CH3, and GH4 arrival time means acquisition of the time when the IC tag further associated with CH3 arrives at GH4. means.

  Then, in the GH4 of the levee body which is the next transport destination of concrete, the arrival of the IC tag 82 of the crane bucket 92 is monitored over time in the IC tag detection area 350 and detected. Then, under the control of the display control unit 334, information indicating the blending type regarding the blending information in the concrete shipment management is finally displayed on the display panel 383 from the wireless AP 381 via the wireless AP antenna 382.

Next, with reference to FIG. 7, the initial setting of the concrete shipment management system and the monitoring process during operation will be described.
When the administrator turns on the power of the shipping management apparatus 110, the system is started and the shipping management application is automatically started. The following processing is performed under the control of the shipment management control unit 332.
In the initial setting operation, first, various initial setting information is read from the setting information DB 301 (S701). Here, the initial setting value stored in the setting information DB 301 is acquired only at the time of initial setting, and exists as a file that is physically independent of the shipping management application. Therefore, even when the shipping management application is operating, It is possible to rewrite and overwrite information on the initial settings.

  When the initial setting in S701 is completed, a procedure for confirming communication as wireless communication, detecting an IC tag in the monitoring area of the IC tag as IC tag communication, and specifying the IC tag for operation of shipping management Transition to. Specifically, for wireless communication connecting between hoppers (BP, CH, GH), a network diagnosis program (for example, ping) for connection confirmation by communication toward a wireless AP (including an antenna) installed in each hopper : Specify the IP address of the computer or communication device that you want to check the connection, usually send data of about 32 bytes, whether there is a reply from the other party, how long it takes if there is a reply, etc. The network is diagnosed based on the data) (S702).

Next, from the result of the network diagnosis based on data such as whether or not there is a reply from the partner of the network diagnosis program executed in S702 and how long it takes, there is a connection between the device and The operating state is determined (S703).
As a result of the determination in S703, when it is determined that the device is operating normally, the green lamp of the operation display device 120 is turned on and the red lamp is turned off, and the connection information (FIG. 11D) is displayed on the display 115 of the shipping management device 110. ) Is displayed (S704). On the other hand, as a result of the determination in S703, if it is determined that a failure has occurred in a device including an unconnected device, the green lamp of the operation display device 120 is turned off and the red lamp is turned on, and connection information (FIG. )) Is displayed (S705).
When the green lamp is turned on in the previous S704, the initial setting is normally completed (S706).

  When the initial setting is completed and the actual operation is started, the operation status of the system by the IC tag detection from each hopper is displayed on the operation display device 120 and the display device 115. That is, the display 115 includes system operation information (FIG. 11A), IC tag operation information (FIG. 11B), (first communication means) device connection information (FIG. 11C), and The hopper connection information (FIG. 11D) by the second communication means is displayed. FIG. 11 shows an example in which a plurality of BPs, CHs, and GHs exist. The IC tag operation information (FIG. 11B) includes an IC tag detected in the IC tag detection area of each hopper, the tag number associated with the shipping management control unit 332, and the IC tag. , The position information (hopper name) obtained by detecting the IC tag, the combination type obtained from the associated combination information, and the battery capacity [%] of the IC tag.

  As described above, when the green lamp of the operation display device 120 is lit, the device has been operating normally since the initial setting as the completion of startup after startup, and the system is operating normally during operation Can be confirmed. In addition, when the red lamp of the operation display device 120 is turned on, it is possible to confirm that a failure including an unconnected device has occurred since the initial setting and that a system failure has occurred during operation. In this way, by displaying the system operation status on the operation display device 120, it is possible to confirm the normal operation / failure occurrence status of the system without being a dedicated administrator or operator.

FIG. 8 is a flowchart showing the process of checking the IC tag battery capacity in one embodiment.
After the initial setting is completed normally, IC tag information is received every time an IC tag is detected, and this processing is executed at that timing. This process is performed under the control of the shipment management control unit 332.

  First, the BP2, CH3, and GH4 hoppers check whether or not the IC tags attached to the trucks and buckets can be detected by the radio station antennas 142, 204, and 352, respectively (S801). If the IC tag has not been detected as a result of the confirmation, the processing in step S801 is repeated, and the IC tag information is read when the IC tag is detected (S802).

  The IC tag is detected by each hopper of BP2, CH3, and GH4, and the read IC tag information (IC tag number and battery capacity) is stored in each of the wireless AP antennas 152, 212, and 360 of the wireless communication units 140, 210, and 360. It is connected via 362 and transmitted to the shipment management apparatus 110 in the plant operation room 1. The IC tag number acquired from each IC tag is transmitted to the shipping management device 110 and collected, so that the shipping management control unit 332 confirms that the wireless communication status of this system in the operating status is normal. (S803).

  Then, the information indicating the battery capacity in the IC tag information acquired via wireless communication is compared with the threshold value (for example, 10% or less setting for the remaining amount set in advance by the initial setting). (S804). As a result of checking the remaining battery level, if it is determined that the current battery capacity is equal to or greater than the threshold value and the IC tag can be used continuously, the process proceeds to step S805 for displaying the battery capacity of the IC tag. Then, the IC tag operation information including the battery capacity of the IC tag (FIG. 11B) is displayed on the display 115. At the same time, the operation display device 120 installed in the plant operation room 1 is lit with a green lamp notifying that the system is operating normally (the red lamp warning the abnormality is turned off) (S805).

On the other hand, if the detected battery capacity is equal to or less than the threshold value as a result of the battery capacity check, it is necessary to replace the battery for the IC tag, and the process proceeds to step S806. Then, the IC tag operation information (FIG. 11B) including the battery capacity of the IC tag is displayed on the display 115, and the orange lamp of the operation display device 120 blinks to prompt the replacement of the battery for the IC tag. (S806).
Thereafter, the process proceeds to step S801 for IC tag detection confirmation in each hopper.

FIG. 9 is a flowchart showing a series of processing for concrete shipment management.
This process is performed after the initial setting process is normally completed under the control of the shipment management control unit 332.
In BP 2, a truck 91 with an IC tag 81 stands by at the entrance / exit gate where the IC tag detection area 140 is installed, and waits for loading of the concrete produced by mixing.

  This process is started when the message information 102 is transferred from the plant control apparatus 100 to the shipping management apparatus 110. When receiving the message information from the plant control apparatus 100 (S901), the shipping management control unit 332 determines whether the message type is a placement start received in the placement unit (S902). When message information is not received, this step S901 is circulated until concrete manufacture is completed.

If it is determined in step S902 that the message type for starting placement has been received, the placement start log is stored in the output log information DB 302 (S903).
In addition, when it is determined in step S902 that the blending information or the message type of placement completion has been received, the blending information received in the shipping unit (multiple times when concrete is shipped by truck from BP2) and the placing unit It is determined whether or not the placement end selection received is received (S904). As a result, in the case of the blending information received in the shipping unit, the process proceeds to S905 where the concrete shipping process is performed. In the case of the placement end received in the placement unit, the placement end log output (S907) for obtaining the placement end log in the output log information DB 302 is selected.

Here, the quality of the concrete until the concrete is transported to GH4 via CH3 after acquiring information about the blending based on the concrete punching design image from the blending information of message information 102 at BP2. Information related to this shall be managed. At that time, the received blending information is stored in the blending information column of the message information, and, for example, blending information and the manufacturing time are displayed on the display panel 383 of the placement site display unit 380 as the production-controlled concrete information. (S905).
This completes one transport of concrete from BP2 to GH4. After completion of shipment of the concrete, a shipping unit log is output to acquire the shipping unit log in the output log information DB 302 (S906).

When the concrete design needs to be shipped a plurality of times in the hit design image, the blending information shown in the message type is sent to all shipping units for the batch (mixed # 1 to #n). On the other hand, when it is determined that the message type of the placement end received in the placement unit has been received (S904), the placement completion log for obtaining the placement completion log in the output log information DB 302 is output. (S907).
This completes one shipment of concrete from BP2 to GH4.

  In this way, a series of processing in the concrete shipment management is executed, and a log is acquired in the output log DB 302 of the shipment management apparatus 110 when a placement start / shipment (composition information) / placement end message is received. In addition, information regarding the quality of the concrete (mixing type and mixing end time) is displayed on the display panel 383 installed at the placement site as a result of shipment management. Can confirm the quality of the concrete.

  Here, calculation of information on the quality of the concrete displayed on the display panel 383 (mixing type / mixing end time) will be described. The blending type is classified into detailed blending numbers from the combination of materials, and the type converted from blending number to blending type based on the blending table 303 is displayed on the display panel 383 at the placement site. For example, in the case of # 4 and formulation No. 2201, the formulation type “B2” is displayed.

According to the present embodiment, even after the concrete is shipped, it is possible to accurately grasp and manage the placement amount, the concrete manufacturing process, the transportation process, and the like based on the hitting design image.
Moreover, according to the present embodiment, not only the concrete shipment management but also the operation management of the transportation means such as trucks and buckets, the progress management to the placement work in the construction period, the management in the de-energization construction other than GH4, etc. Can be managed by skillfully using the information to be output and the log information to be output.
In addition, by moving the installation location within the construction period and transporting means that are added to the lane, by adding an IC tag or moving or adding the first communication means and the second communication means, It is possible to add to existing systems flexibly.

Next, the concrete shipment process will be described with reference to FIG.
Execution of the concrete shipment process is started from the transition of step S904 in which the blending information received in the above-described shipment unit is received.
First, at the beginning of shipping management, message information 102 including formulation information (composition number) 101 is generated while referring to the formulation information DB 103 of the plant control apparatus 100. Then, when receiving the message information 102 of the placement unit from the plant control apparatus 100, the blending type corresponding to the blending number is obtained while referring to the blending table 303 (S1001).

Here, when receiving the start of placing the message information of the placement unit from the plant control apparatus 100, the operation of the shipping management of this system is started. Each time concrete is mixed and manufactured in a predetermined unit, it enters a reception standby state for receiving the blending information.
At this time, in BP2, an empty track 91 loaded with an IC tag is waiting for entry in the IC tag detection area 140, and in CH3, an empty track 91 loaded with an IC tag and a bucket 92 are entered in the IC tag detection areas 201 and 202. In the waiting state, in GH4, an empty bucket 92 loaded with an IC tag is waiting to enter the IC tag detection area 350 of GH4.
Then, when the wireless communication unit 150 receives the blending information from the hub device 130 of the plant operation room 1, since the production of concrete has already been completed, the mixing production time and the filling time are considered from the reception time (for example, Start manufacturing time management (from about 1 minute before).

When the IC tag 81 mounted on the track 91 is detected in the IC tag detection area 140 of BP2 (S1002), the IC tag information is read and acquired (S1003). On the other hand, if the IC tag is not detected, the confirmation processing in step S1002 is repeated until it is detected.
Then, the shipment management control unit 332 associates the IC tag number obtained from the acquired IC tag information with the blending type corresponding to the concrete blending number obtained by referring to the blending table 303. Further, the combination information associated with the IC tag number in this way is created and output in a log for each batch (mixing), and stored in the placement amount log of the output log information DB 302 (S1004). At the site, a truck 91 loaded with concrete moves from BP2 to CH3 (arrow X in FIGS. 1A and 1B).

  After the blending information acquired at BP2 is stored in the placement amount log #i of the output log information DB 302, the same processing is performed at CH3. That is, it is confirmed whether the truck 91 loaded with concrete enters the IC tag detection area 201 of CH3 (arrow X in FIG. 1B) and detects the IC tag 81 (S1005). When the IC tag 81 of the track 91 is detected, the IC tag information is read and acquired (S1006). On the other hand, when the IC tag 81 is not detected, this process is repeated until the IC tag is detected.

Further, when the bucket 92 returns from GH4 to CH3 (arrow Y in FIG. 1B) and the detection of the IC tag 82 mounted on the bucket 92 is confirmed in the IC tag detection area 202 (S1007), at that time Then, the IC tag information is read and acquired (S1008). This detection process is also repeated until the IC tag 82 of the bucket 92 is detected.
Then, the concrete is transferred (taken over) from the truck 91 to the bucket 92. The bucket 92 loaded with concrete moves from CH3 to GH4 (arrow Y in FIG. 1B).
Here, the pouring of the concrete from the truck 91 into the bucket 92 is performed by automatic control or manual operation by an operator. In automatic control, it is possible to guarantee continuity in system processing by automatically detecting a delivery by a sensor or the like and detecting that a confirmation button by an operator or an operation start button of a transportation means is pressed by a manual operation. In any case, when the concrete is shipped from the previous hopper to the next hopper, the concrete is loaded during operation, and the IC tag detection at the end of transportation is judged as completion of shipment due to arrival of concrete, and the shipment is managed. The

  In steps S1006 and S1008, in confirming whether the IC tags 81 and 82 of both the truck 91 and the bucket 92 that take over the transport of concrete are detected (S1009), by detecting both the IC tags 81 and 82, It is determined that the concrete has been transshipped from the truck 91 to the bucket 92. And the IC tag information of the track and bucket acquired in the processing of steps S1006 and S1008, the position information (hopper name) obtained by detecting the IC tag in each hopper, and the blending information received by the plant control device 100 in the shipping unit Are managed in association with each other. If unconfirmed, this processing step S1009 is repeated.

Next, the same processing is performed in GH4. When the bucket 92 loaded with concrete enters the IC tag detection area 350 of GH4 (arrow Y in FIG. 1B), detection of the IC tag 82 mounted on the bucket 92 is confirmed in the tag detection area 350 (S1011). When the IC tag 82 is detected, the IC tag information is read and acquired (S1012). If the IC tag 82 has not been detected, this process S1011 is repeated.
The normality of the association between the IC tag information of the bucket 92 acquired in step S1012 and the blending information received from the plant control apparatus 100 in units of shipment is determined (S1013).
In the normality determination, the concrete blending information included in the message information received from the plant control apparatus 100 has been normally transmitted to BP2, CH3, GH4. In other words, the shipping unit blending information (mixing type from the blending table 303) In the order of the IC tag number of each transportation means detected at the bases from BP2 to CH3 and GH4. On the other hand, although concrete was shipped in BP2 and the IC tag number of the transportation means could be detected, if the IC tag of the transportation means could not be detected in the subsequent CH3 and GH4, it is determined as abnormal. In both cases of normal end and abnormal end, a shipment unit log as a concrete shipment result is created and stored in the output log information DB 302.

As a result of the determination, if it is determined to be normal, the shipment management control unit 332 calculates the blending type / mixing end time as information regarding the quality of the concrete, and the display control unit 334 includes the wireless AP 381 and the wireless AP antenna. The quality information of the concrete, which is “shipment management information”, for example, the blending type “A1” and the production time “15:35” is displayed on the display panel 383 via S382 (S1014). This display blinks for a few seconds and then remains lit until the next display switching.
On the other hand, if it is determined that there is an abnormality, the display control unit 334 controls the display of “ERROR” and displays “ERROR” on the display panel 383 (S1015). This display blinks for a few seconds and then turns off.
With these display controls, display information is transmitted to the display board 383 via the wireless AP 381 and the antenna 382.

  In the previous S1004, message types A, B, and C (placement start, blending information, placement end) of message information (FIG. 6) from the plant control apparatus 100 are received during concrete production, and a placement start log, Whereas the placement amount log (FIG. 4) is output and stored, the shipment unit log is stored as a result of shipment of the concrete produced by mixing as a management unit, which is a delimiter for one placement design fraction. When the placement is finished, a placement completion log is output and stored in the output log information DB 302 (S1016).

  According to this system, when the concrete shipment associated with the blending type in the placement unit and the shipping unit is normally performed from the message information, or when the association with the blending type is abnormal, such as during the placement, Since each log is stored in the output log information DB 302 when a change occurs in the log, the log information stored in the output log information DB 302 is output even after the bucket reaches the final point (the dam body hopper). Thus, the information displayed on the display unit 115 can be confirmed, and the concrete shipment management information can be traced.

FIG. 12 shows an example of displaying concrete quality information on a wireless terminal in another embodiment.
In the present invention, information on the quality of the concrete (mixing type and mixing end time) is displayed on the display panel 383 installed at the placement site using wireless communication means. According to another embodiment, a wireless terminal can be connected to the wireless AP antenna 382 of the placement site display unit 380 to display various information including concrete quality information. This wireless terminal has a display unit and an input unit, and is, for example, a wireless terminal possessed by a field supervisor. 12A to 12D show examples of display screens of the wireless terminal.

(A) shows a display example of “mixing type, production time (mixing end time)” of concrete manufactured in GH4 (Unit 1 and Unit 2) of the levee and transported to the setting site, and the menu column Includes “cumulative placement amount, cumulative placement amount (composition), blending switching” and the like.
The cumulative placement amount of (B) is calculated by calculating the cumulative value of the placement amount [m ³ ] (= rice) stored in the shipment unit in the shipment unit log (FIG. 4) and displaying it as the cumulative placement amount. .
The cumulative placement amount (mixing) in (C) displays information rearranged for each blending type as “cumulative placement amount by blending”. Further, in the composition switching, the cumulative value of the placement amount [m ³ ] (= rice) for each composition is calculated and displayed.
(D) Mixing switching displays the switching time for each mixing type and the mixing type before and after switching.
Note that the display in FIG. 12 is an example, and it is possible to display the display by modifying or applying the shipment management information according to the user's request.

  As described above, according to the concrete shipment management system of the present embodiment, only the tag number is written once in advance on the IC tag used in the shipment management and is mounted on the transporting means, and BP2, CH3, GH4. IC tag number and tag battery in the process of reading only by detecting the IC tag mounted on the concrete transportation means entering and exiting each base of the IC and operating the IC tag (without any writing process) By obtaining the information, the concrete blending information included in the message information output from the plant control device is BP2, CH3 by associating the blending information of the shipping units at the bases from BP2 to CH3, GH4 in order. It can be determined whether the signal has been transmitted normally to GH4.

In addition, since the composition information and IC tag information are associated and stored in the output log information DB as a log, the concrete information based on the striking design image in the dam construction and the shipment amount of concrete actually mixed and shipped Information can be managed centrally.
In addition, according to the present embodiment, since each base that relays the transport of concrete is wirelessly communicated, one control computer (shipment management device) is also provided for a base on the opposite shore over 50 m and a base on the bottom of the valley. 110), the transport status of the shipped concrete can be grasped and processed in real time, so that time stamps and communication of each data can be performed between multiple control computers and computers as in the prior art. Periodic time synchronization can be eliminated.

In addition, at the placement site where the placement is carried out while moving on the levee, information on the concrete quality (mixing type, mixing production time, etc.) is placed when the concrete is transported to GH4 of the levee. By displaying on the display panel provided at a position that can be seen by the site operator, the site supervisors perform the placement work while confirming the quality of the concrete that is manufactured according to the design site and transported to the site. can do.
In addition, as an incidental effect of using a non-contact type IC tag for the first communication means, operation management of a transport means (truck or crane bucket) for transporting concrete is raised. For example, when carrying concrete of buckets by using multiple lanes of multiple trucks and cranes, it may be several hundred units a day when there are many, and as a mechanism to monitor speed violations, overloading, etc. It is possible to use it as a truck and bucket operation management system by measuring, recording and managing departure / arrival times and loading capacity by tags.
And since the 2nd communication means is constructed by long-distance wireless LAN over 50 [m] by the backbone, it uses the wireless terminal etc. at the dam construction site to send the concrete shipment management information. It is possible to receive and display in real time.

Furthermore, concrete placement in dam construction is not limited to the elevation (storage level) in the dam body, but, for example, weakens the energy of water flowing down from the dam, called a damaging work. Since there are also shipments for placing concrete to facilities (not shown) constructed to prevent scouring such as revetments, even in the construction of equipment different from the dam body implemented during the construction period, It is possible to manage the shipment of concrete based on the hitting design drawing for the placing unit and the shipping unit.
In addition, this invention is not limited to the said Example, It can implement by changing variously and applying.
