トンネル内計測システム、計測地点ユニット及び計測地点ユニットの制御装置

Abstract

To provide a tunnel measurement system, a measurement point unit, and a control device of the measurement point unit to facilitate installation and removal of the measurement device when measuring pressure distribution in a tunnel and monitor the measurement status by the measurement device when controlling the measurement of pressure distribution inside the tunnel.SOLUTION: Communication cables are communicably connected in series via communication connectors for measurement points of a plurality of measurement point units and communication connectors for an arithmetic processing unit in an arithmetic processing unit. In addition, transmission paths are connected in series through transmission connectors for the measurement points of the plurality of measurement point units and transmission connectors for reference measurement points in a reference measurement point unit so as to be able to transmit the reference physical quantity. Further, each time the communication cable measurement value acquisition instruction signal is intermittently transmitted, a first display indicating that measurement value acquisition is instructed to the corresponding measurement point unit is made on the corresponding individual display unit, and the display unit is controlled so that a second display indicating an update of the measurement value is displayed on a separate display unit that can be distinguished from the first display at the corresponding measurement point unit each time an updated measurement value signal is received.SELECTED DRAWING: Figure 1
