Storage environment monitoring system

Abstract

The invention discloses a storage environment monitoring system which is composed of a wireless data collection terminal, an integral total control end and a remote data server. The wireless data collection terminal uses a single-chip microcomputer as a core controller. A temperature sensor, a humidity sensor and a carbon dioxide sensor collects real-time air data. The collected data is sent to the integral total control end through 433MHz wireless communication. The integral total control end stores received data in a micro hard disk and displays real-time data, queries historical data and carries out data upper and lower limit alarming through a touch screen. The integral total control end is further connected with an internet through a 4G wireless network, transmits warehouse integral data to the remote data server, stores the large data of a plurality of warehouses for a long term and carries out publishing through the internet, in this way, the related personnel can queries the environment condition of the warehouse by mobile phones at any place. According to the invention, the cost is low, the structure is simple, the transmission is reliable, and the cost performance is relatively high.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a storage environment monitoring system. Background technique [0002] In recent years, with the continuous development of the fresh fruit and vegetable market, the number of fresh fruits and vegetables stored has gradually increased, the storage time has been further extended, and the requirements for the storage environment have become higher and higher. Environmental factors that affect the storage of fresh fruits and vegetables mainly include temperature, humidity, and carbon dioxide concentration. If these conditions are not met, a large amount of storage loss will be caused. Therefore, the requirements for intelligent storage monitoring technology are getting higher and higher, and the existing technical equipment is not enough to meet the requirements of modern storage monitoring systems. A modern intelligent storage monitoring system is urgently needed t...

Problems solved by technology

This technology has the following disadvantages: ①Warehouse monitoring points often change the location of the monitored object due to various reasons, but the wired cables cannot be flexibly re-deployed with environmental changes, and the flexibility is poor; ②The temperature and humidity in the traditional wired online monitoring system The positions of the monitoring instrument and the carbon dioxide monitoring instrument are fixed, and it is inconvenient to disassemble, install, debug, and calibrate. Moreover, the wiring of the wired network is complicated, and it is difficult to check line faults, which increases construction and maintenance costs. Re-layout of the instrument requires re-wiring; ③For In places where the working environment is relatively harsh, the data signal line is easily damaged and aged. For some reasons, the cable may be disconnected or short-circuited. In addition to affecting the normal operation of the monitoring system, it may also become a hidden danger of storage accidents.
