Temperature real-time collection device

Abstract

The invention belongs to the technical field of temperature measurement, and discloses a temperature real-time collection device. The temperature real-time collection device is provided with temperature measurement devices, each temperature measurement device is connected with a temperature measurement cable, each temperature measurement cable is provided with a plurality of temperature measurement points, and a digital temperature sensor is arranged at each temperature measurement point; each temperature measurement device is connected with a repeater through wireless signals, the repeaters are located at the outer side of a granary and are connected with concentrators through wireless signals, and the concentrators are connected with a main control computer through data buses. Accordingto the temperature real-time collection device, the temperature measurement devices automatically read temperature data and measurement point position data of the temperature measurement cables, in wireless modes such as LORA, the temperature data and the measurement point position data are sent to the repeaters, each temperature measurement device supports the temperature measurement cables of 32temperature measurement points at most, advanced wireless spread spectrum communication technologies and sensor technologies in current Internet-of-Things technologies are adopted, temperature parameters of the granary are remotely and automatically measured, collected, subjected to data statistics, and analyzed; compared with traditional manual measurement modes, the temperature measurement efficiency and the temperature measurement accuracy are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of temperature and humidity measurement, in particular to a real-time temperature acquisition device. Background technique [0002] Grain temperature and humidity are one of the important indicators to ensure the safe storage of grain. Only by timely and accurately measuring the temperature and humidity data at all levels of the grain pile, and analyzing the grain storage situation based on the detected temperature data, make decisions and take measures , in order to minimize the loss of grain during storage. [0003] my country is a large country with a large population. Scientific grain storage is a major event to ensure people's food supply and promote social stability. The monitoring of granary temperature plays an important role in scientific grain storage. In most grain storage enterprises, it is still mainly relying on manual detection of the temperature of the granary. Due to the large area of ​​th...

AI Technical Summary

Problems solved by technology

[0006] (1) Manually monitoring the temperature of the granary has a large workload and a long detection cycle, which is easy to miss; due to the untimely detection and alarm, the phenomenon of grain loss in the warehouse occurs from time to time;

[0007] (2) The degree of intelligence is low, the monitoring data can only be uploaded by cable, the monitoring data cannot be stored, or the amount of stored data is limited, and the data cannot be fully utilized for analysis and early warning;

[0008] (3) The wiring is complicated, the wiring of the whole granary is complicated, the cost is high, and the upgrade is difficult; the existing wireless monitoring method has a short transmission distance, which is not suitable for granaries in remote areas, and only traditional wired methods can be used

[0009] (4) There are few detection items. The existing system mainly focuses on temperature and humidity, which cannot be extended to measure other data, such as CO 2 Gas concentration, pest density, air pressure, etc.
