Abstract
The utility model discloses an intelligent oil gas flame detection device which comprises a flame sensor, a signal processing module, a singlechip, a display module and a communication module, wherein the flame sensor collects the flicking frequency of the flame and the radiation intensity of light and transmits the collected signals to the signal processing module; and the signal processing module processes the signals and then transmits the signals to the singlechip, and the output end of the singlechip is connected with the display module and the communication module respectively. The flame detection device can effectively solve the flame-less phenomenon of the existing flame detection device and ensures the combustion safety and stability of a boiler.
Description
Technical field
The utility model belongs to the electronic measurement and control field, particularly a kind of flame detector system that is used for various fuel oils, gas fired-boiler.
Background technology
In the large electric power plant unit; In order to guarantee boiler safety, operation reposefully; Must carry out real time monitoring to the flame combustion situation of boiler,, stop the fuel supply when guaranteeing boiler extinguishment so that interlock with the fuel control unit of boiler; Prevent that inflammable substance from building up in burner hearth or pipeline, detonation takes place even cause the bursting of boilers.
In order to overcome the problems referred to above, mode commonly used at present is to adopt visible light formula flame detecting device, yet, in long-term application process, can find that fiery situation of difficult often appears seeing in this fire monitor equipment.Analyzing its reason, mainly is that flame is blocked by impurity in the combustion process, causes flame intensity to weaken greatly, loses fiery phenomenon; In addition; When the sight line of this fire monitor equipment through or near the Hei Long district; When then inactive when burner and other burner in the burner hearth still continued the operation burning, the signal strength signal intensity that said fire monitor equipment senses had increased than original on the contrary, and phenomenon has just taken place to steal a glance at for this; Cause testing result inaccurate, thus the security that influence is produced.
The utility model content
The utility model technical problem to be solved is to defective and deficiency in the aforementioned background art, and a kind of oil gas intelligent flame checkout gear is provided, and it can effectively solve the fiery phenomenon that loses of existing fire monitor equipment, guarantees the security and the stability of boiler combustion.
The utility model is for solving above technical problem, and the technical scheme that is adopted is:
A kind of oil gas intelligent flame checkout gear comprises flame sensor, signal processing module, single-chip microcomputer, display module and communication module, and the flame sensor is gathered the flicker frequency of flame and the radiation intensity of light, and sends into signal processing module; Signal processing module is sent into single-chip microcomputer after signal is handled, and the output of single-chip microcomputer connects display module and communication module respectively.
Above-mentioned flame sensor comprises probe, photoelectric switching circuit and the core circuit that is linked in sequence.
The front end of above-mentioned probe also is provided with dustproof eyeglass.
Above-mentioned signal processing module comprises filter amplification circuit and the D/A converting circuit that is linked in sequence.
After adopting such scheme, the utility model can reflect current flame burning situation immediately exactly, has avoided loseing fire and has stolen a glance at phenomenon; The adding of single-chip microcomputer can gather and handle signal fast; Intelligentized parameter management software can meet the parameter of the present situation according to the automatic adjustment of different combustion positions most; Go out flame burning degree and state through quantization means, guarantee that boiler safely and steadily runs continuously.
Description of drawings
Fig. 1 is the integrated stand composition of the utility model.
The specific embodiment
Below will combine accompanying drawing, the technical scheme of the utility model will be elaborated.
As shown in Figure 1, the utility model provides a kind of oil gas intelligent flame checkout gear, comprises flame sensor, signal processing module, single-chip microcomputer, display module and communication module, introduces respectively below.
The flame sensor is used for the flicker frequency of sensing flame and the radiation intensity of light, and sends into signal processing module and carry out data, and described flame sensor comprises probe, photoelectric switching circuit and the core circuit that is linked in sequence; Wherein, probe can adopt optical sensor, is used to gather optical signal; And send into photoelectric switching circuit, and convert optical signal into the signal of telecommunication, carry out noise processed through core circuit again; Send into signal processing module, thereby improve the accuracy of data; In addition, in order to improve certainty of measurement, also the front end at probe is provided with dustproof eyeglass, to isolate flame and probe.
Signal processing module comprises filter amplification circuit and D/A converting circuit; Wherein, The input of filter amplification circuit connects the output of aforementioned core circuit, and signal is carried out filter amplifying processing, sends into D/A converting circuit then; Convert data signal into analog signal, send into single-chip microcomputer again and further handle.
Single-chip microcomputer is handled to the received signal, and sends into display module, shows the analog signals consistent with current flame intensity, thereby flame burning degree and state are quantized, and supplies operating personnel's reference; In addition, single-chip microcomputer also can carry out telecommunication through communication module, thereby the parameter current of flame is sent to DCS (Distributed Control System, scattered control system) system.
Need to prove; Consider the practicality of practical operation, can the flame sensor be integrated on the circuit board, and other parts all are integrated on another piece circuit board; (be flame sensor with signal processing module between) uses cable to be connected between two circuit boards; Can reduce volume on the one hand, be convenient to operation, also can reduce whole cost in addition.
In sum; A kind of oil gas intelligent flame of the utility model checkout gear; Focus on utilizing the radiation intensity of flicker frequency and the light of flame come comprehensive judge flame to have that it's too late strong and weak; And utilize single-chip microcomputer to handle the signal that probe is sent here fully independently, show the actual value of flame, and can select 0 to 10 volt of voltage range and 4 to 20 milliamperes of outputs of current range.
Above embodiment is merely the technological thought of explanation the utility model; Can not limit the protection domain of the utility model with this; Every technological thought that proposes according to the utility model, any change of on the technical scheme basis, being done all falls within the utility model protection domain.
