Embodiment Construction

[0018] As shown in Figure 2, the distributed formaldehyde monitoring system based on CAN bus is mainly composed of a central monitoring host (host computer), PC-CAN adapter card, and intelligent nodes.

[0019] The monitoring software runs on the central monitoring host, which can monitor each section in the wood-based panel manufacturing process in real time, including alarm, ventilation and data recording. At the same time, on the central monitoring host computer, using modern control theory, neuron and other methods, a self-learning expert model with multi-variable uncertain systems is constructed. This model can find out the nonlinear relationship in the existing complex record data, and can Prediction to achieve process optimization. In order to use the central monitoring host as a node on the CAN bus, a data card with bus control function is required: PC-CAN bus adapter card, on this basis, the central monitoring PC can be used as the upper computer. At the same time, t...

Abstract

The computerized intelligent on-line monitoring system for the harmful volatile amount of artificial board and its product in timber industry includes front end devices, formaldehyde monitoring network based one CAN bus and one computerized control terminal. One self-learning expert model containing multiple variable uncertainty system is established by means of modern control theory, neuron, etc for the statistical treatment and analysis of acquired monitoring data and the remote diagnosis and calibration of in-situ units.

Description

technical field [0001] The invention relates to a monitoring and control technology and method for controlling the environmental indicators of wood-based panels in the production process, which is used for monitoring and controlling various related processes in the production process, so as to optimize the environmental indicators such as formaldehyde of the product and meet the requirements of the national wood-based panel release standard. Limited mandatory standards to ensure the health and safety of our people. The invention belongs to the field of wood-based panel production and detection, and can monitor and control the formaldehyde release amount and concentration of each process link in the wood-based panel production process in real time. The relationship between the release of volatile matter in the production process and the qualified rate of finished products, establish a relationship model between product qualification and product production process, and then real...
