Temperature and humidity monitoring and recording integrated device for sweet cherry culturing greenhouse

Abstract

The invention discloses a temperature and humidity monitoring and recording integrated device for a sweet cherry culturing greenhouse, which relates to integrated equipment for agricultural greenhouse cultivation, and comprises a power transformation unit, a signal conversion unit, a signal processing unit, a signal amplification unit, a monitoring value and set value display unit, an intelligent processing unit, a data memory cell, a control unit and an execution unit. The device carrying out multipoint remote monitoring on the temperature and humidity in a sweet cherry culturing greenhouse, so the high-precision wide-range dynamic regulation and control on temperature fields and humidity fields which are formed at different heights and different positions are realized, the stable high yield of the sweet cherry culturing greenhouse are also realized, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to joint control equipment for agricultural greenhouse cultivation, in particular to a temperature and humidity monitoring and recording joint control device for sweet cherry cultivation greenhouses. Background technique [0002] The use of cultivation greenhouses to produce sweet cherries can make sweet cherry fruits ripen in advance, and the average annual income is increased by 5 to 10 times compared with the same area of ​​open field production. Due to the significant economic benefits, a large number of various forms of sweet cherries have appeared in domestic cherry production areas in recent years Cherry cultivation greenhouses, but limited by the technical level, economic base, and cultivation experience in protected areas, many problems have also appeared. Especially for the monitoring of temperature and humidity in the greenhouses, the traditional methods of mercury column, red mercury column, The kerosene column glass r...

[0002] The use of cultivation greenhouses to produce sweet cherries can make sweet cherry fruits ripen in advance, and the average annual income is increased by 5 to 10 times compared with the same area of ​​open field production. Due to the significant economic benefits, a large number of various forms of sweet cherries have appeared in domestic cherry production areas in recent years Cherry cultivation greenhouses, but limited by the technical level, economic base, and cultivation experience in protected areas, many problems have also appeared. Especially for the monitoring of temperature and humidity in the greenhouses, the traditional methods of mercury column, red mercury column, The kerosene column glass rod temperature and hygrometer and the mechanical induction temperature and hygrometer are used as the basis for regulation and control. Due to the slow response speed and backward function of the above-mentioned traditional instruments, the temperature and humidity formed by different positions, different heights and different times in the greenhouse The difference in temperature and humidity makes it difficult to accurately monitor, especially at night and in rainy and snowy weather. Frequent entry and exit of the greenhouse is required. Although the labor intensity is high, it is impossible to accurately monitor the temperature and humidity values ​​in the greenhouse. There are low temperatures below 5°C and 30 The risk of high temperature above ℃, and the sweet cherry produced in the greenhouse is an off-season fruit, which is particularly sensitive to low temperature below 5°C during the flowering stage and high temperature above 30°C during the ripening stage. Once it occurs, it will cause serious decline in yield and quality , and even cause partial extinction
