Abstract: The present invention relates to a system for light-based signal exchange between a plurality of formwork panels (P). The formwork panels (P) are equipped with a light hub (LH) which serve to transmit light pulses in a light channel inside the formwork panel (P) to the directly adjacent panels. Respective acknowledgment signals are received in order to discover the existence of the other light hubs (LH) being present in the constructional setting. All the signals are aggregated in one master light hub (mLH) which is in data exchange to a main unit (MU), which may serve as gateway to a secondary computer system (2C). The data transmission is executed according to a predefined protocol.

Abstract: A transmitter for predicting stress on a formwork element during and/or after pouring a building material, in particular concrete, into a space enclosed by a formwork including the formwork element, the formwork element comprising a form face and a support structure which is attached to the form face and supporting the form face, wherein the form face is separated from or integrated into the support structure, the system comprising data acquisition means, at least one sensor unit, a control unit and a transmission unit.
