Background technology
Along with boiler in the fields such as large-scale thermal power, petrochemical industry power station, city heat supply, blast furnace waste gas burning use increasing, the safety of boiler is more and more important to personal security, economic benefit, social stability.Therefore, implosion and quick-fried, the generation that reduces boiler explosion accident outward occur in order to prevent boiler, national regulation must be equipped with " boiler furnace safety monitoring system (FSSS) " to large-sized boiler, and wherein flame detection equipment is the core of FSSS system.
At present domesticly mostly adopt split type flame detecting device, but in long-term application process, find, this fire inspection exist steal a glance at serious, safeguard complicated situation.Analyze its reason, mainly contain 2 points:
(1) early stage flame detection theory and technology are not very perfect, make the reality genus that of the problem of stealing a glance at be difficult to avoid;
(2) split type fire inspection is made of flame detecting probe and fire inspection processor two parts, and needs cable to connect between the two, and this has just increased complicacy and the degree of difficulty safeguarded.
Based on above analysis, the inventor studies improvement to existing flame detecting device, and this case produces thus.
Summary of the invention
Technical matters to be solved by this invention is at the defective in the aforementioned background art and deficiency, and a kind of integral intelligent flame detecting device is provided; it can effectively solve the problem of stealing a glance at of existing structure; guarantee flame burning stability and security, good economy performance is easy to safeguard.
The present invention is for solving above technical matters, and the technical scheme that adopts is:
A kind of integral intelligent flame detecting device, comprise the flame sensor, select filtration module, automatic gain amplification module, central processing module, first via voltage detection module, the second tunnel voltage detection module, display module, communication module and output module, select the output terminal of the input end connection flame sensor of filtration module, flame sensor sensed data is carried out sending into the automatic gain amplification module after the filtering; The input end of first via voltage detection module connects the flame sensor, and output terminal connects central processing module; The input end rabid ox disease of automatic gain amplification module connects selects filtration module and central processing module, and output terminal then connects the second tunnel voltage detection module; The input end of central processing module also connects the second tunnel voltage detection module, and output terminal connects display module, output module and communication module respectively.
After adopting such scheme, the present invention can reflect current flame burning situation immediately exactly, avoid stealing a glance at phenomenon and safeguarded complicated situation, intelligentized parameter selects software can meet the parameter of the present situation according to the automatic adjustment of different combustion positions most, by quantizing to express flame combustion degree and state, guarantee that boiler safely and steadily runs continuously, reduce cost and maintenance simultaneously effectively.

Select the input end of filtration module to connect the flame sensor, according to low frequency, the high-frequency parameter that the user selects, select filtering to handle, can adopt circuit structure shown in Figure 2.
The input end of first via voltage detection module also connects the flame sensor, AC signal is changed into the direct current signal of effective value, by integral operation circuit and smoothed filter circuit, to the mean direct voltage of central processing module output waveform.
The input end of automatic gain amplification module connects output terminal and the central processing module of selecting filtration module respectively, size according to first via voltage detection module output voltage, automatically select the gain multiple, to amplify through filtered data and handle, send into the second tunnel voltage detection module again, its circuit structure can be with reference to shown in Figure 3.
The input end of the second tunnel voltage detection module connects the output terminal of automatic gain amplification module, by the mean direct voltage of computing waveform after the central processing module output filtering.
Cooperate shown in Figure 4, the main output according to the second tunnel voltage detection module of the computing of central processing module, the output of the second tunnel voltage detection module divided by general enlargement factor and auto-gain enlargement multiple, again in conjunction with other parameters such as flame background values, calculate the final mass of flame, and the having or not of definite flame.
Display module, output module and communication module are connected the output terminal of central processing module respectively, wherein, display module is used for showing in real time that current flame burning situation, output module are used for the previous combustion data are exported, as shown in Figure 5, communication module then is used for carrying out telecommunication.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of doing on the technical scheme basis all falls within the protection domain of the present invention.
