INFORMATION PROCESSING
Analogue / digital signal processing is realized by one or more modules endowed with a microprocessor, by means of electronic units, such as: optocouplings, optical transistors, galvanic transformers, separation transformers, video survey cameras, infra-red passive sensors, thermal resistors, capacitive microphones, etc.
These transducers ensure the necessary voltage by means of some digital circuits (called A/D or D/A converters) to the microprocessor system for transforming the signals in data packages.
Data packages are transformed in communication protocols, such as:
RS232, TCP/IP, etc.
The radio unit (GSM/GPRS/PCS) transforms these protocols in radio waves of 900/1800/1900 MHz and at the other end of the receiving point, will take place the opposite process, necessary for decoding and transforming the signals in the data base compatible with the PC system.
