Intelligent boiler control system

Abstract

The invention discloses an intelligent boiler control system, which comprises a controller, a keyboard module, a detection module, a failure processing module and an alarm prompting module, wherein the output end of the controller is further connected with a liquid crystal display. On the basis of a singlechip technology, a temperature sensor, a pressure sensor and a water level sensor are fully used for monitoring the temperature, pressure and water level of a boiler; when the boiler is in an unsafe state according to detection, the failure processing module is started automatically; an electromagnetic valve is used for controlling water feeding, a relay is used for controlling a blower, and the risks of water depletion, overpressure and over-temperature of the boiler are prompted and alarmed through voice prompts, LED (Light-Emitting Diode) prompts and a loudspeaker, so that the running reliability and safety of the boiler are effectively improved, the service life of the boiler is prolonged, and explosive incidents are reduced; and moreover, the intelligent boiler control system is low in production cost, and contributes to popularizing.

Description

technical field [0001] The invention belongs to the technical field of control systems, and in particular relates to an intelligent boiler control system capable of simultaneously monitoring water level, temperature and air pressure. Background technique [0002] The boiler is an energy conversion device. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc., and after conversion by the boiler, it outputs steam, high-temperature water or organic carrier with certain heat energy. Boilers play an important role in people's production and life, and the monitoring of boilers is particularly important. Currently, boiler systems are used to monitor and manage the safe operation of boilers. [0003] The traditional boiler control system has the following disadvantages: 1. It often only monitors a certain factor in the boiler environment, and the safety performance is not high; 2. The traditional bo...

AI Technical Summary

Problems solved by technology

[0003] The traditional boiler control system has the following disadvantages: 1. It often only monitors a certain factor in the boiler environment, and the safety performance is not high; 2. The traditional boiler control system generally only detects danger and alarms, and does not perform fault processing or backup processing There are too few measures, and the safety factor is low; 3. After the boiler is used for a certain period of time, its pressure resistance and stability will gradually decline, and its durability is not strong

[0004] There are various potential safety hazards in the existing boiler control system, especially boilers commonly used in domestic boilers and sugar factories, coal factories, steel factories, etc. Due to the relatively simple prevention and control settings and low safety, explosions occur from time to time, not only Caused casualties, but also brought certain economic losses
