Digital display touch type speed regulation controller of full-automatic feeder

Abstract

The invention discloses a digital display touch type speed regulation controller of a full-automatic feeder. An electric circuit of a controller is formed by connecting a power switch (1), a fuse circuit (2), a zero cross detection circuit (3), a relay J1 driving protection material throwing indication circuit (4), a relay J1 contact protection circuit (5), a speed regulation driving output circuit (6), a protection circuit (7), a touch input setting circuit (9), a display drive circuit (10), a single-chip microcomputer (11), a clock circuit (13), a power indication circuit (12), a rectification voltage stabilizing circuit (14), a transformer (15), an emergency switch (16), and a terminal (8). The digital display touch type speed regulation controller uses the strong anti-interference single-chip microcomputer as a core control element, and the controller is simple in input setting, high in time precision, good in control function, stable in speed regulation performance. The digital display touch type speed regulation controller realizes full-automatic speed regulation control of a feeder.

Description

technical field [0001] The invention relates to a controller, in particular to a digital-display touch-type speed-regulating controller for a fully automatic feeding machine. Background technique [0002] In the field of aquaculture, feeding machines have become an indispensable farming machinery in the aquaculture industry. The work of the feeding machine is realized by the controller. Existing controllers use mechanical timers to control the length of the feeding machine's working time and use resistance-capacity elements, time-based circuits, potentiometers or switch conversions to control the feeding gap time. There are many defects: ① using a metal gear type timer, it is easy to cause the gear to rust in a humid environment and cause the timing failure; ② using a timer with an all-plastic gear structure, although it is not easy to rust, it will If it is too large or too strong, it will easily cause the plastic shell to crack and be damaged; ③Mechanical timers generall...

AI Technical Summary

Problems solved by technology

There are many defects: ① the metal gear type timer is used, and the gear is easy to rust in a humid environment, resulting in failure of the timing time; If it is too large or too strong, it will easily cause the plastic shell to crack and be damaged; ③Mechanical timers generally have low timing accuracy; ④The time accuracy of the feeding gap is affected by the performance of electronic components, parameter accuracy, adjustment indicator position, installation position and use The impact of the environment makes it difficult to achieve consistent time accuracy for controlling the feeding gap, and the performance is unstable; ⑤There is no stable, non-pulsating speed control function; ⑥There is no automatic control function, so that there is no automatic control function on the market. feeding machine
