Online performance and durability monitoring system for pulsator of milking machine

Abstract

The invention relates to an online performance and durability monitoring system for a pulsator of a milking machine. The online performance and durability monitoring system is especially suitable for online performance and durability monitoring of the pulsator of the milking machine under experimental and production conditions. During monitoring, analog quantity signals outputted by each high-frequency-response vacuum sensor connected into a pulsation pipeline are acquired in real time by an AD (analog-to-digital) acquisition board, and monitoring of 15 vacuum pulsation signals can be realized maximally at the same time by the system. A computer reads digital quantity signals converted by the AD acquisition board through a USB (universal serial bus) signal amplification extension cord and performs analysis, calculation and storage to automatically complete various tests of the pulsator of the milking machine. A transmission distance of the USB signal amplification extension cord is longer than 10m, so that testing personnel can avoid a noisy operating environment of the milking machine as far as possible. Due to portability of a test chamber, the requirement on mobile testing can be met.

Description

technical field [0001] The invention relates to an on-line performance and durability monitoring system of a milking machine pulsator, which is particularly suitable for on-line performance and durability monitoring of the milking machine pulsator under test and production conditions. Background technique [0002] With the popularization of milking mechanization technology, the performance and working conditions of milking equipment have gradually become the focus of the industry. The pulsator is the key executive part of the milking machine, and its performance and reliability directly affect the performance of the milking machine. In order to ensure that the performance and reliability of the milking machine pulsator meet the design requirements, the on-line performance and durability monitoring of the milking machine pulsator must be carried out under test or production conditions. At present, domestic enterprises and institutions do not have a dedicated on-line performa...

AI Technical Summary

Problems solved by technology

The problem with this method is that the operator must operate and be on duty on site, and it is difficult to achieve automatic real-time online performance and durability monitoring requirements. At the same time, the working environment of the milking machine is very noisy, which has a great impact on the test operators, especially in It is very inconvenient to monitor the durability of the milking machine pulsator
