Abstract:
1. A system for measuring a load on a bridge when being traversed by a vehicle, the system comprising: a plurality of measuring modules each having a plurality of measuring channel units with A/D converters; a plurality of separate strain gauge sensors associated with said measuring modules, and provided for attaching on the bridge, said strain gauge sensors transmitting analog measurement signals in a wired manner to said measuring channel units assigned to them in each case, said measuring channel units deriving digital measurement data from the analog measurement signals by means of said A/D converters; a POE switching module; a local server/router; a remote evaluation unit, the digital measurement data being transmitted from said local server/router via a radio data transmission to said remote evaluation unit; and said measuring modules each having a respective transmission interface and connected in parallel and in a wired manner to said PoE switching module and via said PoE switching module to said local server/router, as a result of which a local network (LAN) is formed, in that said local server/router keeping said measuring modules in synchronicity.
