The invention discloses an intelligent stepless speed regulation controller of a feeder. The intelligent stepless speed regulation controller of the feeder is formed by connecting a safety circuit (1), a reset switch (2), an emergency switch (3), a self-locking circuit (4), a transformer T1 (15), a rectifying voltage-stabilizing circuit (5), a zero cross detection circuit (13), a single-chip microcomputer U2 (18), a power indication circuit (6), an input setting circuit (7), a drive protecting circuit (14) of a relay J1, a drive protecting circuit (9) of a relay J2, a material flinging indication circuit (8), the relay J1, the relay J2, a speed regulation drive output circuit (10), an output protecting circuit (11) and a binding post (12) in a circuit mode. According to the intelligent stepless speed regulation controller of the feeder, the AD-interface single-chip microcomputer is used as a core control element, and input setting is easy; in this way, the intelligent stepless speed regulation controller of the feeder has the advantages of being good in control performance, convenient and safe to use, high in reliability, convenient to produce and debug and simple in structure.
Description
technical field [0001] The invention relates to a controller, in particular to an intelligent stepless speed regulation controller of a feeding machine. Background technique [0002] With the development of mechanization in the aquaculture industry, feeding machines are widely used, and the work of feeding machines is realized by the controller. Up to now, there is no stable stepless speed regulation controller, even if some only use the The rectangular wave that changes the duty ratio formed by the time base block, the band switch, and the resistance-capacitance element drives the thyristor to change the output voltage with step-by-step speed regulation. Due to the influence of the performance of electronic components, parameter accuracy, poor contact of mechanical contacts and the use environment, the failure rate of mechanical timers is extremely high, the speed regulation of the motor is very unstable, it is easy to stall, and the use effect is extremely poor, so it cann...
