Liquid or solid particle monitoring system - has separate display monitors that record data and feed to master computer for processing

摘要

The particle monitoring system has separate particle monitors (1) that record and store data, each having their own key-pad and visual display unit. The data is read and processed by the central master computer (2), which represents the data graphically as a function of time and/or location. If only two monitors are deployed the master microcomputer is not absolutely necessary for possible processing of recorded data to reveal behavioural trends. Unlike the monitors (which would be battery powered), the master microcomputer 2 requires mains power. In operation, each monitor functions under its own real-time calendar clock. The clocks are used to control the acquisition of data and can be used to initiate a synchronised start between several remote monitors, the start-time having been programmed into the monitor some time earlier.
