Abstract:
A method for counting and measuring particles illuminated by a light beam, providing two-way wireless communication between a data processing and control system and a remote particle detecting system, said method comprising the steps of:forming in said data processing and control system at least one of control signals, which provide a turning-on, turning-off and switching of modes of operation of said remote particle detecting system; conversing said control signals to the form for wireless transmission; wireless transmitting of the conversed control signals from said data processing and control system to said remote particle detecting system; wireless receiving of the transmitted control signals by said remote particle detecting system; conversing the received control signals to the form for control of said remote particle detecting system; sensing by a light detecting means of a particle detecting means of said remote particle detecting system a light created by an intersection of said light beam and said particles within a particle monitoring region and providing an output, which is effectively indicative of a size of said particles; processing said output by a signal processing system of said remote particle detecting system; forming in said signal processing system of said remote detecting system a data, containing an information about a quantity and said size of said particles; conversing said data, containing said information about said quantity and said size of said particles to the form for wireless transmission; wireless transmitting of the conversed data, containing said information about said quantity and said size of said particles, from said remote particle detecting system to said data processing and control system; wireless receiving of the transmitted data, containing said information about said particle quantity and size, by said data processing and control system; conversing the received data, containing said information about said quantity and said size of said particles to the form for processing; processing the conversed data, containing said information about said quantity and said size of said particles, by said data processing and control system.
