Described is a process for monitoring in real time the differential subsidence of the ground in which a structural drawer is housed, the process starting by a sensing step using strain gages and temperature sensors coupled to the structural drawer and the rolling rails respectively, producing analogical signals due to the compression and tension stress of the structural drawer, the obtained analogical signals being subsequently conditioned by the instrumentation integrated circuits so as to be read, processed and converted by a micro controller into digital signals to be sent through wireless radiofrequency modules to the receptor, which performs the inverse process, i.e., receives the digital signals through an antenna and a radiofrequency module, and are processed by a microcontroller and sent to a Monitoring and Digital Communication Unit, which is intended to generate a database with the obtained signals and send it to the communication and services network of the Collective Trans port System. It is worthy to mention that the transmitter system is fed by solar power (clean power) obtaining therefore an autonomous power system. |
