A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor based data loggers which communicate with 16-bit 8086 based microcomputers, and data base management software for archiving data. Various versions of the data aquisition system (DAS) exist. The latest version is based on the Timex/Sinclair 1000 (TS1000) microcomputer. It also contains the capability of controlling diversion structures in combined sewer networks. All data loggers can be connected to drop counting precipitation sensors or standard tipping bucket raingauges. Data is stored on audio cassette tapes in the field. The data can be transmitted to IBM-PC compatible microcomputers through their serial ports and archived in a central data base by a time series manager. The data is then easily retrievable for computer modelling.
