Abstract

The invention discloses a constant-flow automatic water replenishment control system based on signal peak-cutting processing, which is characterized in that it mainly consists of a single-chip microcomputer, a solenoid valve and a peak-cutting circuit connected to the single-chip microcomputer, and a V / It consists of an F conversion module and a water level sensor connected to the V / F conversion module. The V / F conversion module in the present invention can limit and filter the waveform of the detection signal while converting the detection signal, so as to improve the stability of the detection signal, so that the single-chip microcomputer can better identify the detection signal, Compared with the comparison, it is better to control the opening and closing of the solenoid valve, so that the water volume of the feeding pool can be more accurately controlled to meet the drinking water needs of poultry.

Description

technical field

[0001] The invention relates to the field of automatic control, in particular to a constant-flow automatic water replenishment control system based on signal peak-shaving processing. Background technique

[0002] During the poultry breeding process, the breeder must feed the poultry with water every day. The traditional method is to manually feed the poultry. However, with the continuous expansion of the breeding scale, the traditional water feeding method will cost a lot of labor costs. In order to solve the above problems, an automatic water feeding device has appeared on the market at present. The automatic water feeding device uses a water level sensor to monitor the water volume in the feeding pool. water volume. The automatic water feeding device is used to feed poultry, which can effectively replace manual water feeding and save a lot of labor costs. Yet the automatic water feeding device that uses at present still has very big defect, promptly the c...

Embodiment

[0023] Such as figure 1 As shown, the present invention is mainly composed of a single-chip microcomputer, a solenoid valve, a peak clipping circuit, a V / F conversion module and a water level sensor. Wherein, the signal output interface of the water level sensor is connected with the input terminal of the V / F conversion module, which is used to detect the water level in the water feeding pool and output corresponding electrical signals to the V / F conversion module, which needs to be set inside the water feeding pool ;The water level sensor adopts AL200W piezoresistive water level sensor, the AL200W piezoresistive water level sensor can accurately measure the liquid pressure proportional to the liquid level depth, and convert it into a standard electrical signal output, and establish the output signal and liquid depth The linear corresponding relationship, so that the liquid level from the end of the water level sensor to the liquid surface can be measured, and the water volume...
