Device for detecting temperature and humidity in refrigerating space

Abstract

The invention relates to a device for detecting the temperature and the humidity in a refrigerating space. The device is technically characterized in that a temperature and humidity sensing unit comprises a sensing unit singlechip microcomputer, a temperature and humidity sensing element, a D / A converter, a signal amplifier, an A / D converter and a sensing unit resetting circuit; a detection unit comprises a detection unit singlechip microcomputer, an RS-485 chip, a power supply module and a detection unit resetting circuit; the detection unit singlechip microcomputer is connected with the sensing unit singlechip microcomputer and is used for receiving temperature and humidity data acquired by the sensing unit; the detection unit is connected with a main station through the RS-485 chip and an RS-485 bus to realize a data communication function of the main station. The device disclosed by the invention is reasonable in design; the temperature and the humidity in the refrigerating space can be detected in real time and be uploaded to the main station for processing, so that a main station monitor can learn about the temperature and humidity data of the refrigerating space in time, and the main station monitor can process the data in time; therefore the quality of agricultural product storage and transportation preservation is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of temperature and humidity detection, in particular to a temperature and humidity detection device in a refrigerated space. Background technique [0002] Due to the seasonal and regional characteristics of agricultural products, it is very important to refrigerate agricultural products to keep them fresh, so that consumers can enjoy healthy and diverse foods. However, there are also many problems in this process. How to ensure that the food is always in its most suitable environment during storage and transportation is the most important problem that needs to be solved. [0003] The storage temperature of most agricultural products is relatively low, and fruit and vegetable agricultural products need to be stored in a high humidity environment. Therefore, the temperature and humidity in the storage, transportation and preservation environment of agricultural products are two extremely important monitoring indicat...
