Regarding the construction support system, measurement management method and construction support method used.

Conventionally, there is a possibility that a track or a road surface may be displaced due to vibration during traveling and a natural environment to cause a problem. For example, Patent Document 1 proposes a track deviation measurement system for measuring the displacement of a track or the like. ..

In Patent Document 1, a plurality of reference rods having a predetermined length, one end of which is fixed to a structure and sequentially arranged in the horizontal direction, a target provided at the other end of each reference rod, and a position corresponding to each target. It is fixed to the structure and consists of a non-tactile displacement sensor that measures the horizontal distance from the target. For example, it is possible to measure vibration during train running and displacement due to the natural environment at low cost. Has been done.

Such displacement of the track or road surface may occur due to the action of the pressure of the chemical solution when, for example, construction such as injection of the chemical solution is performed in the vicinity. That is, since there is a possibility that the track or road surface may be displaced due to the construction in the vicinity of the track or road surface, for example, the construction is performed while monitoring the displacement of the track or road surface by the measurement method proposed in Patent Document 1. However, it is operated so that construction will be stopped when the tendency of displacement of the track or road surface is detected.

However, the place where the measurement result for measuring the track and the road surface is managed and the construction place where the chemical injection is performed are separated, and the place where the measurement result is managed and the construction place are connected by a communication line and transmitted. In many cases, the construction is performed while checking the measurement results at the construction site. Therefore, for example, there is a possibility that the measurement result cannot be received in real time due to a communication abnormality, and the construction cannot be stopped even if there is a problem in the track or the road surface due to the construction.

Sets the time required for one measurement by the link type displacement meter 100a to be 90 seconds. The predetermined time may be set as appropriate.

When the condition is set (step s1: Yes) or after the condition is set (step s2), the construction by the chemical injection device 210a and the measurement by the link type displacement meter 100a are started (step s3).
Then, when the construction by the track 120a and the measurement by the link type displacement meter 100a are started, the failure detection process is executed by the control unit 11 of the measurement result management terminal device 10, and the above-mentioned "double start", "disconnection", and so on. When any of "insulation failure", "failure", "level abnormality", and "communication abnormality" is detected and the information is received by the communication abnormality detection terminal device 40 (step s4: No), the monitoring monitor display unit Since the detection result may be displayed on the "error information" display unit 473 of 470 and the measurement result by the link type displacement meter 100a may not be reflected, the communication abnormality detection terminal device 40 may not be able to reflect the measurement result. The construction stop information is transmitted to the construction management terminal device 200, the construction is stopped by the chemical solution injection device 210a via the construction management terminal device 200 (step s9), and the measurement management is completed.

When a failure is not detected by the failure detection process by the control unit 11 of the measurement result management terminal device 10 (step s4: Yes), the measurement result information from the link type displacement meter 100a is actually stored in the storage unit 12 of the measurement result management terminal device 10. In addition to being stored as measurement result information, it is transmitted from the measurement result management terminal device 10 to the measurement result management server 20 via the Internet In, and is stored in the storage unit 22 as measurement result information. Further, the measurement result receiving terminal device 30 receives the stored measurement result information stored in the storage unit 22 of the measurement result management server 20 via the Internet In, and stores it in the storage unit 32 as the received measurement result information (step). s5).

Further, the measurement result management terminal device 10 executes the alarm determination process, compares the actual measurement result information stored in the storage unit 12 with the alert level which is the set condition, and the measurement result is among the alert levels. When the warning value level is exceeded (step s6: No), the determination result is displayed on the "warning value information" display unit 472 of the monitoring monitor display unit 470, and the warning display unit 462b of the warning light display unit 462 is displayed. The alarm unit 15 and the alarm unit 35 are operated (step s7).

If the determination result by the alarm determination process exceeds the alert level but is at the "alert value" level that can be constructed (step s8: Yes), the process returns to step s5 and the transmission / reception of measurement result information is continued.
On the contrary, when the judgment result by the alarm judgment process exceeds the warning level and the construction is impossible at the "stop value" or "limit value" level (step s8: No), the measurement result is received from the communication abnormality detection terminal device 40. The construction stop information is transmitted to the construction management terminal device 200 via the terminal device 30, the construction is stopped by the chemical solution injection device 210a via the construction management terminal device 200 (step s9), and the measurement management is completed.

If the alarm determination process by the measurement result management terminal device 10 does not exceed the alert level (step s6: Yes), the control unit 41 executes the time comparison process (step s10), and at that time, the comparison target is used. The actual measurement result information, the stored measurement result information, and the received measurement result information are displayed on the "measurement result time information" display unit 476.

As a result of the time comparison process, the time information (measurement time) included in the latest actual measurement result information among the actual measurement result information which is the measurement result information stored in the storage unit 12 of the measurement result management terminal device 10 and the measurement. Result The time during which the time information included in the latest received measurement result information among the received measurement result information, which is the measurement result information received by the result receiving terminal device 30 via the measurement result management server 20, does not match.

Since the time interval is set to be longer than the time interval based on the measurement time required for the measurement by the (link type displacement meter 100a), the measurement result information received by the measurement result receiving terminal device 30 can be used as the latest measurement result and for determining whether or not construction is possible. It is possible to determine whether or not the data is valid, and it is possible to determine whether or not the measurement result information stored in the measurement result management terminal device 10 is the latest measurement result. Therefore, it is possible to determine whether or not construction is possible based on the measurement result information in real time.

Further, when executing the time comparison process, the system and configuration of the management time in the measurement result management terminal device 10 and the measurement result receiving terminal device 30 are different from those of the measurement result management terminal device 10 and the measurement result receiving terminal device 30. Since the comparison is made with the management time in the communication abnormality detection terminal device 40, which is a control device, a more accurate comparison can be performed.

Further, since the link type displacement meter 100a, which is arranged along the track 120a and measures the displacement of the track 120a, is used as the measuring device 100, the displacement of the track 120a can be accurately measured and reflected in the construction. ..

Further, the measurement management system 1 is used to execute a failure detection process for detecting a failure between each device, and an alarm judgment process for outputting an alarm related to construction based on at least one of the judgment result by the measurement management and the detection result by the failure detection process. Therefore, it is possible to detect a failure in the measurement management system 1, for example, it is not possible to receive measurement result information in real time based on not only a communication abnormality but also a system failure, and a problem has occurred in the track 120a or the road surface due to construction. However, it is possible to reliably prevent the occurrence of a situation in which the construction cannot be stopped, and it is possible to output an alarm.
