  In FIG. 1, the example in which the data transmission unit 41 transmits the temperature data to the data reception unit 11 based on the timing measured by the timer 51 is shown. However, the data transmission unit 41 and the data reception unit 11 are Instead of a device capable of transmitting and receiving data, the management device 1 side is requested to transmit temperature data from the temperature sensor side, and the temperature data is transmitted from the temperature sensor side to the management device 1 accordingly. Also good. By doing in this way, it becomes possible to acquire temperature data at the timing of the management apparatus 1 side.

  Next, a method for installing the temperature sensor 31 on the concrete member 2 to be managed will be described with reference to FIG. FIG. 2 is a schematic diagram showing a state in which the temperature sensor 31 shown in FIG. 1 is installed on the concrete member 2. As shown in FIG. 2, the temperature sensor 31 embeds a sheath tube and installs it inside. As the material for the sheath tube, a material having a high thermal conductivity and a smooth outer surface is selected. As a result, the temperature inside the sheath tube becomes the same as the temperature near the surface of the concrete member 2, and accurate temperature detection is possible. After the concrete is hardened, the sheath tube can be easily removed. The sheath tube and sensor can be removed. The hole formed in the trace of the removal of the sheath tube is filled by repair, and the removed sheath tube and the temperature sensor are used for measurement of the next member.

  Next, with reference to FIG. 3, the structural example of the whole intensity | strength management apparatus in the construction site of a building is demonstrated. A management apparatus 1 shown in FIG. 1 is installed in a data management room such as an office. The place where the concrete member is placed is divided into three types, “manufacturing yard”, “stock yard”, and “building”. The temperature sensor 31 that detects the temperature of the concrete member 2 in each yard and the ambient temperature are detected. A temperature sensor 32 is installed. The temperature sensors 31 and 32 and the management apparatus 1 are connected by a wireless communication line.

  Next, the operation of the management apparatus 1 will be described with reference to FIG. First, an operation in which the management device 1 collects temperature data of the temperature sensors 31 and 32 will be described. First, the timers 51 and 52 output date information at a predetermined time interval (for example, every 20 minutes). The data transmitters 41 and 42 that have received the date information read the detected temperature values output from the temperature sensors 31 and 32. Then, the data transmission unit 41 transmits temperature data including date and time information output from the timer 51, an identification number assigned in advance to the temperature sensor 31, and the read detected temperature value to the data reception unit 11. . The data transmission unit 42 transmits temperature data including date and time information output from the timer 52, an identification number assigned in advance to the temperature sensor 32, and the read detected temperature value to the data reception unit 11. .

  The data receiving unit 11 receives the temperature data transmitted by each of the data transmitting unit 41 and the data transmitting unit 42 and outputs the temperature data to the temperature data collecting unit 13. In response to this, the temperature data collection unit 13 can uniquely identify a concrete member (here, the concrete member 2) corresponding to the identification number of the temperature sensor included in the temperature data received by the data receiving unit 11. And the installation location (manufacturing yard, stock yard, building). In the temperature data collection unit 13, a temperature sensor identification number, a member ID, and installation location information are stored in association with each other in advance. When the temperature sensor detects the ambient temperature, the member ID is an ID that can be identified as the ambient temperature. The temperature data collection unit 13 stores the date and time information and the detected temperature value (the surface temperature or the ambient temperature of the concrete member) in the temperature database 12 for each identified member ID and installation location. As a result, the surface temperature of the concrete member 2 detected at predetermined time intervals and the ambient temperature of the place where the concrete member 2 is installed are written in the temperature database 12.

  Next, an operation in which the management device 1 performs strength management of the concrete member 2 will be described. First, the operation in which the temperature determination unit 15 and the estimation unit 17 estimate the effective age and member strength of the concrete member 2 based on the detected temperature of the concrete member 2 will be described. When the initial strength is developed, the member temperature becomes significantly higher than the ambient temperature due to the neutralization heat generation. For this reason, it is necessary to estimate the member strength at that time based on the member temperature. On the other hand, after the initial strength is developed (after 7 to 10 days after placement), the generation of neutralization heat is converged, and the member temperature gradually matches the ambient temperature. At this time, the member strength can be estimated based on the ambient temperature. In the present invention, using this principle, in addition to the member temperature, the ambient temperature of the member installation location (manufacturing yard, stock yard, and building) is also measured.

  At the time of initial strength expression, the estimation unit 17 estimates the hardening strength of the concrete member 2 based on the member temperature stored in the temperature database 12, and the estimated hardening strength data and identification information for identifying the concrete member 2 The installation location information is written in the management database 14. Curing strength data here is effective age and member strength. Since the process of estimating the effective age and the member strength from the detected temperature is performed using a known process, a detailed description of the process operation of the estimation process is omitted here. On the other hand, the temperature determination unit 15 determines whether or not the member temperature is the same as the ambient temperature with reference to the ambient temperature (air temperature) of the member installation location that is simultaneously detected.

  When it is determined that the member temperature and the ambient temperature match, the temperature determination unit 15 associates the identification information for identifying the concrete member 2 having the matching temperature with the installation location information, and displays information indicating that the temperatures match. Write to the management database 14. The estimation part 17 switches the temperature data used for the strength estimation with respect to the concrete member 2 in which the information indicating that the temperatures match in the management database 14 is written to the atmospheric temperature data. Then, the worker removes the temperature sensor 31 and the data transmission unit 41 embedded in the concrete member 2. The removed temperature sensor 31 and data transmission unit 41 are used for the next member measurement. With this processing operation, the hardening strength data is written in the management database 14 for each concrete member 2.

  In addition, since the temperature sensor 31 shown in FIG. 2 detects only the temperature near the surface of the concrete member 2, the temperature of the center (inside) portion of the concrete member 2 cannot be confirmed. Therefore, the analysis unit 16 may obtain the temperature of the central portion from the temperature near the surface of the concrete member 2 by analysis. At this time, the estimation unit 17 estimates the hardening strength of the central portion of the concrete member 2 based on the temperature data of the central portion obtained by the analysis by the analysis unit 16 and writes the estimated hardening strength in the management database 14. As a result of this processing operation, hardening strength data (effective ages and member strengths for the surface and the center) is written in the management database 14 for each concrete member 2 placed for each installation location.

  Next, an operation for displaying the hardening strength data of the concrete member 2 based on the data stored in the temperature database 12 and the management database 14 will be described. First, the operation of the curing state display unit 19 shown in FIG. 1 will be described with reference to FIG. First, when the operator performs an operation for displaying the hardening state on the management device 1, the hardening state display unit 19 sets the value of the member strength of the hardening strength data stored in the management database 14 to the concrete member 2. It reads out every time and compares with the threshold value memorize | stored in the determination-data memory | storage part 20, and it is determined whether each concrete member 2 is the following three states. The three states here are "curing" indicating that curing is in progress, "demolding OK" indicating that the mold may be removed, and a state where the mold may be moved to another location. There are three "lifting OK" to indicate that there is.

  The determination data storage unit 20 stores two threshold values T1 and T2 that can specify these three states in advance, and the threshold values T1 and T2 have a relationship of T1 ≦ T2. It has become. When the strength of the concrete member 2 is equal to or less than T1, the cured state display unit 19 is “curing”, exceeds T1, and is equal to or less than T2, “demolded OK”, and exceeds T2, “lifting OK”. Is determined. And the hardening state display part 19 performs color classification based on the determination result, and displays each concrete member 2 on the display part 18 by the graphic. FIG. 4 is a screen display example that is displayed in different colors according to the hardening strength (member strength) of each concrete member 2. For example, a member being cured is displayed in “gray” color, a member that is demolded OK is displayed in “green” color, and a member that is lifting OK is displayed in “red” color. Thereby, an administrator or a worker can instantaneously determine the workable state of each member.

  In addition, about the member which has not measured temperature, you may make it estimate and display intensity | strength by numerical analysis, the concrete implantation time difference, etc. In this case, since all the members are displayed, the number of display screens increases, and switching thereof becomes complicated. Therefore, for example, the members to be displayed are not displayed when the predetermined period has elapsed since the expression of strength that can be lifted. do it.

  Next, the operation of the time change display unit 21 shown in FIG. 1 will be described with reference to FIG. First, when the operator performs an operation for displaying the time change of the curing state on the management apparatus 1, the time change display unit 21 stores the temperature data stored in the temperature database 12 and the management database 14. The set hardening strength data is read for each concrete member 2, graphed, and displayed graphically on the display unit 18. FIG. 5 is a screen display example in which the change in time is graphed and displayed on the display unit 18 for the member temperature, effective age, and estimated strength of each concrete member 2. For example, in the member temperature graph, the member temperature is plotted in blue, and the ambient temperature at the installation location of the member is plotted in green. Thereby, an administrator or a worker can instantly determine the time change state of each member.

  Next, the operation of the data list display unit 22 shown in FIG. 1 will be described with reference to FIG. First, when an operation for displaying a data list is performed on the management apparatus 1 by an operator, the data list display unit 22 is stored in the temperature database 12 and the management database 14. The hardening strength data is read for each concrete member 2 and subjected to a data list process, and is displayed graphically on the display unit 18. FIG. 6 is an example in which the basic data of the graph shown in FIG. 5 is displayed as a numerical value, and is displayed when an administrator or the like needs detailed data. FIG. 7 shows an example of displaying a member strength list of all members that have been manufactured. In the example shown in FIG. 4, a limited member is displayed, but this function displays a list of member strengths of all members. To do. This makes it possible to estimate and manage long-term strength.

  In order to manage the strength of members using the principle of estimating the strength of the same material by calculating the effective age from the results of measuring the temperature of the concrete and the surrounding temperature (atmosphere temperature) in this way The member curing period can be shortened by transmitting the detected temperature to the management device one by one by communication and estimating the hardening strength in real time during the production of the concrete member. Further, since the temperature sensor is attached to the concrete member so as to be removable, the removed temperature sensor can be reused, and the measurement cost can be reduced. In addition, since the temperature detected by the temperature sensor is collected at a remote place, the initial and long-term strength of the concrete can be rationally measured. Moreover, since the detected temperature data and the estimated curing strength data are displayed, the manager and the worker can easily recognize the strength development status.

  Next, the intensity | strength management apparatus by the 2nd Embodiment of this invention is demonstrated with reference to drawings. FIG. 8 is a block diagram showing the configuration of the embodiment. In this figure, the same parts as those in the apparatus shown in FIG. The apparatus shown in FIG. 8 is different from the apparatus shown in FIG. 1 in that the data receiving unit 11, the temperature data collecting unit 13, and the temperature database 12 provided in the management device 1 are separated and installed as a data collecting device 10 in a remote place. Is a point. And in order to install the data collection apparatus 10 in the place away from the management apparatus 1, the communication part which performs information communication via the network N which comprises each of the management apparatus 1 and the data collection apparatus 10 with the internet or an intranet 23, 24. Further, when it is detected that the new temperature data is stored in the temperature data database 12, the data collection device 10 attaches the newly stored temperature data to an e-mail and transmits it via the communication unit 24. A mail sending unit 25 is provided. The temperature determination unit 15, the analysis unit 16, the estimation unit 17, the curing state display unit 19, the time change display unit 21, and the data list display unit 22 are attached to an email transmitted by the mail transmission unit 25 via the communication unit 23. The received temperature data is received, and first, the processing operation similar to the processing operation described in the embodiment is executed.

  As described above, since the data collection device 10 and the management device 1 are connected so as to enable information communication via the network 10, the data collection device 10 and the management device 1 are installed at a location far from the site where the concrete member 2 is placed. The management device 1 can perform the determination, analysis, estimation, and display processing of the temperature data. By doing in this way, since the intensity | strength of the concrete member 2 can be estimated from a remote place, a centralized management center is installed in arbitrary places and the member intensity | strength of several site | parts is managed by the management apparatus 1 of one place. It becomes possible. Thereby, since member strength management can be managed collectively, it becomes possible to improve the efficiency of management work.

In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.
