Digital display touch controller of full-automatic feeder

Abstract

The invention discloses a digital display touch controller of a full-automatic feeder. An electric loop of the controller is formed by connecting a power switch (1), a safety circuit (2), a clock circuit (3), a relay J1 drive protection circuit (5), a relay J1 contact protection circuit (6), a material throwing indication circuit (7), a relay J2 drive protection circuit (8), a relay J2 contact protection circuit (9), a touch input set circuit (11), a display drive circuit (12), a power indication circuit (13), a rectification and voltage stabilizing circuit (14), a transformer (15), an emergency switch (16) and a binding post (10). A single-chip microcomputer high in interference prevention performance serves as a core control element, input setting is easy, the time precision is high, the control performance is good, using is safe, and the working reliability is high.

Description

technical field [0001] The invention relates to a controller, in particular to a digital display touch controller of 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 generally have low timing accur...

Problems solved by technology

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 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 Due to the influence of the environment, it is difficult to achieve consistent time accuracy for controlling the feeding gap, and the performance is unstable; ⑤ There is no automatic control function, so that there is no automatic feeding machine on the market
