Abstract

The invention discloses a high-precision temperature monitoring and alarming system for greenhouse planting of figs. The high-precision temperature monitoring and alarming system is characterized by mainly comprising a temperature sensor G, a trigger switch circuit, a non-linear compensation circuit connected with the trigger switch circuit, a linear amplifying circuit connected with the temperature sensor G and the like. The high-precision temperature monitoring and alarming system can filter noise signals in detection signals, so as to improve the precision of greenhouse temperature monitoring, thus growers can better adjust the temperature in a greenhouse. The high-precision temperature monitoring and alarming system can amplify weak voltage signals outputted by the temperature sensor so as to provide high-precision voltage signals for the trigger switch circuit, thus the trigger switch circuit can control an alarm to operate according to the voltage signals more accurately, and the monitoring precision of the high-precision temperature monitoring and alarming system is improved. The high-precision temperature monitoring and alarming system can eliminate the influence of nonlinearity of the temperature sensor on temperature detection, thereby improving monitoring effect thereof.

Description

technical field [0001] The invention relates to a monitoring and alarm system, in particular to a high-precision temperature monitoring and alarm system for growing figs in greenhouses. 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 ...
