Abstract

The present invention discloses an offset temperature monitoring alarm system for fig plantation based on non-linear compensation. The system is mainly composed of a temperature sensor G, a triggering switch circuit, an offset circuit and a non-linear compensating circuit connected with the triggering switch circuit, and an amplifier P1. The offset temperature monitoring alarm system for plantation fig based on non-linear compensation can filter noise signals similar to detection signals so as to improve the accuracy of monitoring the greenhouse temperature and allow the farmer households to regulate the temperature in the greenhouse. The offset temperature monitoring alarm system for plantation fig based on non-linear compensation can perform non-distortion amplification of the detection signals to facilitate the comparison of the detection signals and the setting value so as to accurately monitor the temperature in the greenhouse. The offset temperature monitoring alarm system for fig plantation based on non-linear compensation can eliminate the influence of the nonlinearity of the temperature sensor on the temperature detection so as to improve the monitoring effect of the offset temperature monitoring alarm system provided by the invention.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an offset temperature monitoring and alarm system for planting figs based on nonlinear compensation. Background technique [0002] Figs are rich in nutrients such as amino acids, organic acids, magnesium, manganese, copper and vitamins, and are deeply loved by people. With the development of greenhouse planting technology, figs have been planted in greenhouses. If figs are planted in greenhouses, the yield of figs will increase, and the fruit will be larger and the juice will be more. Because figs are not cold-resistant and have high temperature requirements, a temperature monitoring system is usually used to monitor the temperature in the greenhouse when planting in a greenhouse. When the temperature is too low, the greenhouse needs to be heated in time to ensure the normal growth of figs. However, the existing temperature monitoring system is doped with a large noise signal in the signal...
