Embodiment Construction

[0021] The invention discloses an oven temperature rise monitoring and alarm system for a heating furnace. In order to make the advantages and technical solutions of the invention clearer and clearer, the invention will be described in detail below in conjunction with specific embodiments.

[0022] Such as figure 1 As shown, the hardware structure of the alarm system of the present invention includes a server connected to the real-time database of the enterprise through the local area network, and provides other devices or the client of the server through the local area network. The client mainly has query and viewing functions. The main functions are realized through the establishment of the temperature rise warning unit, real-time data collection, monitoring condition reasoning machine, real-time alarm reasoning machine and client-end result display.

[0023] Among them, the server includes a temperature rise warning unit, a real-time data acquisition unit, a monitoring unit...

Abstract

The invention discloses a monitoring and alarming system for a temperature rise of an oven of a heating furnace. A temperature rise curve module is used for carrying out configuration on a temperature rise curve of an oven by alarm rule configuration software to form an alarm rule base, and an alarm rule table module stores parameter setting; a device real-time database module stores real-time data of needed monitoring parameters collection of a boiler control system or enterprise database into parameter historical data tables in a time sequence; the real-time parameter obtained by refreshing are provided for a real-time alarming unit; and then on the basis of connection of an operation trend module of a client and a real-time data acquisition unit, a current temperature rise curve operation state of the oven is checked, and whether alarming needs to be carried out is selected according to parameters in the historical table based on connection of an alarm implementation module of the client and the real-time alarming unit. According to the invention, the system collects the operation data and carries out real-time reasoning; and when a temperature offset occurs, alarming prompting is carried out.

Description

technical field [0001] The invention relates to the technical field of heating furnace temperature control, in particular to an oven temperature rise monitoring and alarm system for a heating furnace. Background technique [0002] Heating furnaces are used in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries. Due to the relatively poor heat transfer performance of the refractory bricks in the heating furnace, the influence of the temperature difference between the inside and outside of the bricks caused by excessive heating will cause potential safety hazards in later use. Therefore, general heating furnaces have special heating curves when they are baked. These graphs are calculated based on empirical data, physical properties and heat transfer properties of bricks. [0003] When a newly built or overhauled heating furnace is p...
