Green storage and transportation and cold chain logistics supervision system and method based on Beidou system

Abstract

The green storage, transportation and cold chain logistics supervision system based on the Beidou system of the present invention includes an environmental parameter monitoring device, a remote monitoring management system and a remote query platform; it is characterized in that: the environmental parameter monitoring device includes a BD positioning module connected to a microcontroller , temperature sensor, humidity sensor, pressure sensor and weight sensor. The output end of the microcontroller is connected to an alarm circuit, compressor control circuit and pressure supply control circuit, TCP / IP network module and GPRS module. The control method of the environmental parameter monitoring device includes: a) collecting environmental information; b) uploading information; c) judging the weight; d) judging whether the temperature reaches the alarm value; e) judging whether the temperature reaches the automatic cooling value. The system and method of the present invention ensure that agricultural products, aquatic products, food, and beverages are in the best preservation state during preservation, transportation, and storage, avoid previous rot and deterioration, and ensure the safety of stored and transported items.

Description

technical field [0001] The invention relates to a green storage and transportation and cold chain logistics supervision system and method based on the Beidou system, and relates to the field of refrigerated transportation of goods. Background technique [0002] my country is a large agricultural country, and the three rural issues have always played a pivotal role in the development of national production, and agriculture is the foundation of national economic and social development. However, due to the serious lag in the fresh-keeping technology of agricultural products, aquatic products, food and beverages, the quality of the products is unstable, the added value of the products is not high, and even the value is depreciated after the season. This situation has seriously restricted the modernization of the rural economy. According to statistics, about 25% of the fruits and vegetables in the country are lost due to rot and deterioration every year. Yunnan, Guangxi, Fujia...

Problems solved by technology

Grapes and honeydew melons are two famous brand fruits in Xinjiang. However, due to the lack of cold storage and fresh-keeping technology in our country, only 80,000 tons of honeydew melons can be exported out of 600,000 tons, and a large number of grapes cannot be sold to other regions because of poor refrigeration and freshness.
