The ready-mixed concrete management system according to the present invention is a system for managing ready-mixed concrete that is transported to a setting site after being mixed in a ready-mixed plant, and specifically,
・ Data on the mix of ready-mixed concrete,
・ Data on mixing time of ready-mixed concrete,
It is a system that manages the placement of ready-mixed concrete based on this.

In the present invention, the following steps are performed. That is, as shown in FIG.
・ Process to produce ready-mixed concrete by mixing in ready-mixed plant (see S1)
A process of transporting ready-mixed concrete from the ready-mixed plant to a setting site (a set-up site where a ready-mixed concrete is placed to construct a concrete structure, for example, a dam construction site) by a ready-mixed vehicle (see S2).
-Reloading the ready-mixed concrete car's ready-mixed concrete into a bucket at a predetermined place (hereinafter referred to as "reloading place") in the placement site (see S3)
・ Transporting the ready-mixed concrete in the bucket 4 to the place where the ready-mixed concrete is placed (see S4)
・ The process of placing ready-mixed concrete (see S5)

  In FIG. 1, reference numeral 1 indicates a raw concrete plant that manufactures ready-mixed concrete, reference numeral 2 indicates a placement site, and reference numeral 3 indicates a ready-mixed concrete that transports ready-mixed concrete from the ready-mixed plant 1 to the placement site 2. Reference numeral 4 indicates a bucket into which ready-mixed concrete is charged at the placement site 2, reference numeral 5 indicates a transport machine (for example, a crawler crane) that transports the bucket 4, and reference numeral 6 indicates A transshipment site for transshipment of ready-mixed concrete from the ready-mixed vehicle 3 to the bucket 4 is shown, and reference numeral 7 denotes a placement location for placing ready-mixed concrete.

And the ready-mixed concrete management system according to the present invention is:
A data storage medium 10 transported with the ready-mixed concrete from the ready-made plant 1 to the placing site 2;
A writing means 11 arranged on the side of the ready-mixed plant 1 (that is, in or near the ready-made plant 1) for writing data relating to ready-mixed concrete into the data storage medium 10;
Reading means 12 for reading the data written by the writing means 11 from the data storage medium 10 arranged on the side of the placement site 2 (that is, in or near the site of the placement site 2) When,
A display means (monitor) 13 that is arranged on the placement site 2 side and displays data read by the reading means 12;
It has. Here, the data written to the data storage medium 10 is at least
・ Data on the mix of ready-mixed concrete,
・ Data on mixing time of the ready-mixed concrete,
Is included. In addition, "data regarding mixing time of ready-mixed concrete"
-Mixing start time data-Mixing end time data-Time when predetermined work was performed in the ready-mixed concrete (for example, the time when ready-mixed concrete was loaded on the ready-mixed car 3 Means the time at which the kneading start time or the kneading end time can be obtained by calculation. Furthermore, in addition to the above data, the data storage medium 10 may store an identification ID (for example, an identification number) for identifying a live control car, a car number of the live control car, and the like.

  According to the present invention, in the placing site 2 where the ready-mixed concrete is placed, the data relating to the mix of ready-mixed concrete and the data relating to the mixing time of the ready-mixed concrete are displayed on the display means 13, so those data are displayed. Based on the above, it is possible to make an appropriate determination as to whether or not the ready-mixed concrete that has been conveyed can be placed.

  By the way, in the said raw plant plant 1, the process of FIG. 3 is implemented sequentially. That is, the ready-mixed concrete is mixed (see S11 and S12), the ready-mixed ready-mixed concrete is loaded into the ready-mixed car 3 (see S13), and data relating to ready-mixed concrete is written in the data storage medium 10 (S14). The raw concrete vehicle 2 leaves the raw concrete plant 1 together with the data storage medium 10 (see S15). Note that the data writing to the data storage medium 10 may be performed before loading, not after loading the ready-mixed concrete.

  The data storage medium 10 may be a contact type medium such as a USB memory or an SD card, but short-range communication (for example, wireless communication called Type A or Type B, such as an IC tag) (Felica (registered trademark) communication, Bluetooth (registered trademark) communication, infrared communication, etc.) may be used. In the case of the former contact type storage medium, adhesion of cement or mud to the terminal tends to cause a failure, but the latter non-contact type storage medium is preferable because there is no such problem. In the case of a non-contact type storage medium, data can be transmitted and received without an operation of connection or removal, which is also convenient in this respect.

  On the other hand, the writing unit 11 may be configured by a data input unit 110 that inputs the various data described above and a data output unit 111 that outputs the data to the data storage medium 10. Examples of the data input unit 110 include a personal computer having a keyboard, a mouse, and a monitor, and it is preferable that the person in charge inputs various data using the keyboard and the mouse. The data output unit 111 is selected according to the data storage medium 10 such as a USB terminal, an SD card slot, or an IC tag / writer. Note that the data input unit 110 and the data output unit 111 do not have to be arranged close to each other. For example, the data input unit 110 is installed in a raw plant office, and the data output unit 111 is arranged at a place where the ready-mixed concrete vehicle 3 is loaded with ready-mixed concrete or at the exit of the ready-mixed plant 1. And good. When the data output unit 111 is installed at a place where the ready-mixed concrete car 3 is loaded with ready-mixed concrete, the data is read at the timing when the ready-mixed concrete is loaded on the ready-mixed ready-made car 3 (by the ready-mixed car driver or another person in charge) The data may be written to the data storage medium 10 using the output unit 111. When the data output unit 111 is installed at the exit of the raw plant, when the raw control vehicle 3 passes through the outlet (the raw control vehicle Or the other person in charge) may use the data output unit 111 to write the data into the data storage medium 10.

  On the other hand, the above-mentioned reading means 12 includes a data reading unit 120 that reads data from the data storage medium 10 (that is, data related to the mixing of ready-mixed concrete, data related to the mixing time of ready-mixed concrete, and the like), and the data reading unit 120. It is good to comprise by the data transmission part 121 which transmits the data read by this to the said display means 13. FIG. The data reading unit 120 is selected according to the data storage medium 10 such as a USB terminal, an SD card slot, an IC tag reader, or the like. The data transmission unit 121 may include a wireless communication unit. The reading unit 12 and the display unit 13 do not need to be arranged close to each other. For example, the display means 13 is installed in the office of the placement site 2, and the reading means 12 is the transshipment site 6 (a place where the ready-mixed concrete of the ready-mixed car is transshipped into the bucket 4) or the transshipment. It should be installed at the entrance and exit of the place 6. When the reading means 12 is installed in the transshipment site 6, the data is read at the timing before or after the ready-mixed concrete is transferred from the ready-mixed car 3 to the bucket 4 (by the driver of the ready-mixed car or another person in charge). Data may be sent from the storage medium 10 to the data reading unit 120. When the reading means 12 is installed at the entrance / exit of the transshipment site 6, the data may be sent at the installation location. As a result, data stored in the data storage medium 10 is displayed on the display means 13. In that case, not only the data stored in the data storage medium 10 but also the time when the data is sent from the data storage medium 10 to the data reading unit 120 may be displayed on the display means 13. Thereby, the person in charge can know the “replacement time of ready-mixed concrete” from the displayed time (details will be described later).

  Next, an example of the work in the placement site 2 will be described with reference to FIG.

  When the ready-mix vehicle 3 arrives at the transshipment site 6 (see S31), the driver transmits the data in the data storage medium 10 to the display means 13 via the reading means 12 (see S32), and performs other operations. The person reloads the ready-mixed concrete of the ready-mixed car 3 into the bucket 4 (see S33). The display means 13 displays “data related to the mixing time of ready-mixed concrete (for example, shipping time data)”, but the person in charge who sees the display indicates “the time of mixing ready-mixed concrete (or Whether the time taken from “the time when the concrete was shipped” to “the time when the fresh concrete was reloaded” exceeded the reference time (for example, 1.5 hours in the summer and 2.0 hours in other than the summer) Judgment is made (see S34). When the reference time is exceeded, an instruction is issued to other workers, and the ready-mixed concrete in the bucket is disposed of (see S35).

By the way, the bucket 4 may not be filled with the ready-mixed concrete from one ready-mixed vehicle 3, and ready-mixed concrete may be supplied also from the subsequent ready-mixed vehicle 3. For example, when the loading capacity of the ready-mixed concrete car 3 is 4.2 m ³ and the loading capacity of the ready-mixed concrete of the bucket 4 is 2.8 m ³ , 2.8 m of 4.2 m ³ ready-mixed concrete is used. ^{If 3} is inserted, the bucket 4 will be full, but the ready-mixed concrete remaining in the ready-mix vehicle 3 will be 4.2-2.8 = 1.4 m ³ . It is necessary to add 3 ready concrete. For this reason, the person in charge (that is, the person in charge looking at the display means 13) puts the ready concrete into the bucket 4 from only one ready-mixed vehicle or from two ready-mixed vehicles. (See S36). In the former case (that is, when the ready-mixed concrete is put into the bucket 4 from only one ready-mixed vehicle), the bucket 4 is moved to the placement position by the transport device (for example, a crawler crane) 5. An instruction is issued (see S41). On the other hand, in the latter case (that is, when the ready-mixed concrete is put into the bucket 4 from two ready-mixed vehicles), the “data regarding the mixing of ready-mixed concrete” for the two ready-mixed vehicles is It will be displayed on the display means 13, but the person in charge sees the display, “mixing the ready concrete of the first ready-mixed car” and “mixing the ready-mixed concrete of the second ready-mixed car”. Are the same (see S37). If the blending is different, an instruction to dispose of the ready-mixed concrete in the bucket is issued (see S38). If the blending is the same, the bucket 4 is moved to the placement location by the transport device 5. An instruction is issued (see S41).

  Next, the person in charge determines whether or not the “mixing of ready-mixed concrete in the bucket 4” matches the mixing of the placement site (that is, the planned mixing) (see S42). If there is not, an instruction to change the placement location is given (see S43). If they match, the placement time of the adjacent section (that is, the section adjacent to the section where the ready-mixed concrete is to be placed, and the section where the ready-mixed concrete has already been placed, It is determined whether or not the elapsed time from the (time) (that is, the connecting time) exceeds a reference time (for example, 1.5 hours in summer and 2.0 hours in other than summer) (see S44). If the elapsed time is within the reference time, the concrete is instructed to be placed (see S45). If the elapsed time is outside the reference time, the placement location is instructed (see S46).

Incidentally, the data from the reading means 12 may be transmitted not only to the display means 13 but also to a predetermined personal computer or server via a LAN or a network. And that data, for example
・ Data on the preparation of ready-mixed concrete ・ Data on the mixing time of ready-mixed concrete ・ Identification ID to identify the ready-mixed car (for example, identification number)
-The car number of the ready-mixed car is stored in association with the placement location, and predetermined additional data, that is,
・ Transshipment time ・ Bucket identification ID
・ It is advisable to remember the placement time. The additional data may be input through a user interface (drop-down list or list box).

The data as described above may be input to the personal computer or server by the following method. That is, as shown in FIG.
A block diagram (see reference numeral 13A) showing a plurality of sections for placing ready-mixed concrete (for example, all sections for placing ready-mixed concrete);
-Data on ready-mixed concrete put into the bucket 4 (see reference numeral 13B. For example, data on blending of ready-mixed concrete and data on mixing time of ready-mixed concrete)
Is displayed. The numbers from 1 to 43 in the block diagram 13A shown in the figure indicate the planned placement order. Moreover, the table | surface shown by the code | symbol 13B has described the data of the ready-mixed concrete thrown in from the 2 ready-mixed concrete vehicles. When the person in charge designates the section where the ready-mixed concrete is placed next on the display means using a touch pen, mouse or keyboard, the displayed data 13B (that is, the data regarding the mix of ready-mixed concrete and the ready-mixed concrete) Data relating to the mixing time) is stored in the personal computer (storage means) in a state associated with the section. And it is good to print out data when the concrete placement of all the sections is completed.
