Grain depot intellectualization integrated control system and application method thereof

Abstract

A grain depot intellectualization integrated control system comprises an upper computer. The upper computer is connected with output ends of a plurality of repeaters sequentially through a terminal receiver and a router, the repeaters are connected with a warehouse-outside air temperature-humidity sensor, a ventilating device, an LED screen and a plurality of optical fiber temperature-humidity sensor systems, and the input end of each optical fiber temperature-humidity sensor system is connected with a warehouse-inside air temperature-humidity sensor, a gas detector and a plurality of optical fiber temperature sensors. When the grain depot intellectualization integrated control system is used, the optical fiber temperature-humidity sensor systems send the grain temperature, air temperature and humidity and gas information measured by the optical fiber temperature-humidity sensor systems to superior equipment according to communication requirements, and the upper computer carries out monitoring according to downstream data received by the upper computer and gives an alarm when an abnormal condition occurs. According to the grain depot intellectualization integrated control system, not only is distribution of temperature measuring points wide and is positioning performance strong, but also the situation that electronic parts and components are resistant to phosphine corrosion when used for detecting the temperature of grains can be eliminated, a wireless communication structure is adopted so that grain conditions can be monitored remotely, both monitoring effects and safety are strong, and the application range is wide.

Description

technical field [0001] The invention relates to a grain depot control system, in particular to an intelligent comprehensive control system for a grain depot and a method for using the same. It is particularly suitable for combining an optical fiber temperature sensor and a wireless communication structure to improve the monitoring effect and safety of the grain depot. Background technique [0002] Grain reserves are an important guarantee for maintaining national stability and development. Grain temperature detection is an important link to prevent grain from rotten and to preserve quality. In the process of grain temperature detection, due to the large amount of grain and the large volume of the granary, the temperature at different locations is different, so it is necessary to measure at multiple points. [0003] The traditional granary temperature monitoring system uses the thermistor as the temperature sensitive element, and mostly adopts the wired communication structu...

AI Technical Summary

Problems solved by technology

[0003] The traditional granary temperature monitoring system uses the thermistor as the temperature sensitive element, and mostly adopts the wired communication structure. It has the following problems: ①Use the thermistor to detect the temperature, and it is necessary to compensate and correct the output signal of each sensor; ②There is an electrical signal, There are potential safety hazards in the use of granaries ③Electronic components are prone to aging, moisture, and easy to false alarms or even failures ④High false alarm rate and frequent failures, which bring inconvenience to construction and maintenance and high maintenance costs Mechanical damage will occur, and electromagnetic interference will also occur at the same time, affecting the accuracy of the measured temperature ⑥ Phosphine gas used in fumigation is easy to corrode electronic components, especially metal copper, making expensive equipment a disposable product
