Storehouse temperature and humidity environment monitoring system

Abstract

The invention relates to a storehouse temperature and humidity environment monitoring system, and belongs to the field of measurement. The storehouse temperature and humidity environment monitoring system comprises a temperature-humidity sensor, a digital transmitter, a communication bus, a monitoring center, upper computer management software, a temperature adjusting device and a humidity adjusting device; a distributed intelligent network-based monitoring system is used herein, the system is based on field bus transmission mode and has 'serial' network connection structure, field wiring is facilitated, up to 32 acquisition terminals may be connected through a pair of twisted-pair wires, wiring work is reduced, and signal transmission distance is longer than 1,200 m; digital signal transmission is adopted so that no transmission error or signal loss occurs; temperature and humidity of storehouse environment can be detected and monitored and may also be automatically adjusted under uniform control of the monitoring center, storehouse environment temperature-humidity adjusting capacity and management level can be increased greatly, temperature-humidity monitoring can be finished for all storehouse environments with one monitoring computer, management is simplified, and the system is applicable particularly for upgrade modification of existing storehouses.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a detection and monitoring system for a storage object environment. Background technique [0002] The temperature and humidity in the warehouse environment (referred to as temperature and humidity) often affect the quality and performance of the stored goods, and it is necessary to monitor and control the parameters such as ambient temperature and humidity. [0003] At present, many domestic warehouses are equipped with testing equipment such as hygrometers, thermometers, and humidity test paper. Although the temperature and humidity can be continuously monitored manually, this manual testing method is time-consuming, laborious, inefficient, and the temperature and humidity of the test have large errors. Great randomness. [0004] With the rapid growth of the national economy, the circulation of various goods has increased sharply, and various large warehouses have emerged...

AI Technical Summary

Problems solved by technology

[0007] However, these existing warehouse temperature and humidity monitoring systems have the following problems: one is "passive" monitoring, which can only monitor but not control, and the temperature and humidity adjustment of the storage environment still needs to be carried out manually according to the monitoring results; The "parallel" network structure is adopted, and each temperature and humidity transmitter is connected to the monitoring center through a router / switch, forming a "parallel" network connection relationship, which requires a lot of on-site wiring. For large warehouses or field The "reconstruction and expansion" project with warehouses has poor adaptability
