TMS is a system to measure temperatures (T), calculate maturity (M) values at critical locations, such as those identified by B4Cast simulations, and estimate in-place strength (S) at early ages, based on a provided strength-maturity relationship. TMS provides remote monitoring capabilities similar to those described for HeatWatch.
Alarms stored in the TMS software alert the operator if preset temperatures or temperature differences have been exceeded. The TMS also permits automatic control of cooling or heating measures designed by B4Cast simulations.
Besides measuring temperatures, TMS can monitor other sensors that provide an appropriate electrical output. For example, TMS can monitor wind speed, relative humidity, barometric pressure, water levels, strains, corrosion parameters, and crack movement.
Thermocouples are installed at pre-established locations in the structure and connected to the data logger. The TMS software (same as used for HeatWatch) is installed on a PC with a Windows® operating system. Temperatures are recorded by the data logger at desired time intervals from the time of casting. The data are transferred to a PC, either by local area network connection to the logger or by a wireless cell phone connection, allowing remote monitoring of the temperatures and other measured parameters. Strength development at the thermocouple locations can be estimated through the use of pre-established strength-maturity relationship.
The data logger is kept on-site in a watertight case, allowing it to operate in all kinds of weather conditions. Each logger can accommodate up to 48 channels. The amount of data that can be recorded is limited only by the amount of RAM in the computer. The unit has a back-up battery ensuring continuous operation should a power outage occur.
For remote monitoring, the purchaser needs to provide two SIM cards, one for the data logger´s modem and one for a SGM mobile phone connected to the office computer. As many data loggers as desired can be mounted at building sites, each with 48 channels. By phoning the modem of each data logger, the temperature data can be transferred wirelessly to the office computer with the installed software.
The software allows the user to display the temperature history of each channel together with the maturity and estimated strength development. Reports can be printed with full documentation of temperature history, maturity and estimated strength.
