Intelligent monitoring device of biogas engineering anaerobic fermentation system

Abstract

The invention discloses an intelligent monitoring device of a biogas engineering anaerobic fermentation system, which comprises a parameter acquisition system, an executive system, a singlechip control system, an HMI (human machine interface) touch screen and a remote communication control system, wherein the parameter acquisition system comprises a sensor group arranged in a biogas fermentation tank; the singlechip control system comprises a singlechip, a first operational amplifier, a second operational amplifier, a relay group and a first GPRS (general packet radio service) module capable of communicating with a network base station; the singlechip is respectively connected with the parameter acquisition system, executive system, HMI touch screen and first GPRS module; the executive system comprises a feeder, a temperature control device and an alkali addition device; the remote communication control system is provided with a GPRS module group; and the GPRS module group can perform signal transmission with the first GPRS module through the network base station. The intelligent monitoring device can monitor the anaerobic fermentation system in time in places covered with network base station signals without in-situ monitoring of operators.

Description

technical field [0001] The invention relates to the technical field of biogas, in particular to an intelligent monitoring system capable of monitoring the anaerobic fermentation state of a biogas project in real time. Background technique [0002] The core of the biogas project is anaerobic fermentation. The anaerobic fermentation process refers to the process in which organic matter is continuously metabolized and grown by anaerobic microorganisms under certain moisture, temperature and anaerobic conditions to produce flammable gas—biogas, which improves biogas production. The key to the efficiency lies in whether it can provide a stable and good living environment for anaerobic microorganisms, and the most important factors affecting the living environment of anaerobic microorganisms are the temperature of the biogas slurry and the pH value of the biogas slurry. [0003] In the actual biogas engineering anaerobic fermentation system, the biogas slurry formed by mixing orga...

AI Technical Summary

Problems solved by technology

At present, the monitoring equipment for the operation status of the anaerobic fermentation system of the biogas project is not perfect. During the operation process, the manager still needs to monitor and grasp the operation status of the biogas fermentation tank on the project site and make appropriate adjustments. The labor cost of equipment operation is relatively high
