Logic circuit for controlling rainfall intensity of rainfall hall area

The invention relates to a logic circuit for controlling the rainfall intensity of a rainfall hall area. The logic circuit is based on an electronic circuit formed by single-chip-microcomputer control latches, triodes, and a rainfall matrix switch. The single-chip-microcomputer control latches control emitters of the triodes and base electrodes of the triodes are controlled directly by a single-chip microcomputer. Turning on and off of rainfall switches are controlled by cutting off and conduction of triodes, so that rain spraying or stopping of rainfall sprayers can be controlled conveniently and rainfall spraying time of the rainfall sprayers as well as time for stopping rainfall spraying by the rainfall sprayers can be controlled effectively. Whether each rainfall sprayers carry out water spraying can be controlled precisely; time for rainfall spraying each time as well as a time interval for water spraying each two times can be controlled accurately; and the point rainfall intensity at each rainfall spray
