Abstract

The invention discloses a non-contact magnetic measuring element, which relates to a detection control system. The technical scheme of the non-contact magnetic measuring element is as follows: the non-contact magnetic measuring element measures electrical pulse signals formed by the running of a fan blade; then the electrical pulse signals are subject to filtering isolation and pass through a trigger and a catcher; and finally, the processed electrical pulse signals are output to an MPU (micro processing unit) system to count, thereby obtaining the revolving speed value of the fan blade. The non-contact magnetic measuring element provided by the invention has the beneficial effects that because of adopting the technical scheme, the measuring element can measure the revolving speed value of the fan blade, and control the uniformity of a temperature field, thereby guaranteeing the consistency of temperatures of hatching eggs and the birth rate of the hatching eggs.

Description

technical field [0001] The invention relates to a detection control system, in particular to a non-contact magnetic measuring element. Background technique [0002] In the fields of incubation equipment, chemical industry, biopharmaceutical and environmental control, various parameter detection systems are usually installed to measure parameters such as temperature, humidity, air pressure and wind speed, so as to facilitate the operation of the equipment. The control method of the temperature field in the existing incubator is to install a plurality of heating pipes and fans in the incubator housing, install the heating pipes in the middle or rear of the housing, and install the fans vertically in the center of the housing or in a The upper part of the vertical side plate is stirred and blown by a fan to make the hot air circulate in the incubator. Therefore, the parameters of the wind field in the incubator are extremely important. It has a great influence on the uniformit...
