The system can be applicable to the protective systems of various boilers, moreover, the actual flame change can be seen directly by inspectors by the monitor, parameters can be set conveniently by using a touch screen, the debugging is simple, and the occurrence of the situations of misinformation and omission can be precluded.
Description
Technical field
The present invention relates to a kind of a kind of intelligent integral flame checking system that boiler furnace flame is carried out Intelligent Measurement, processing, demonstration and setting protection.
Background technology
At present; in the fuel-burning power plant; boiler furnace safety system (F S S S) all uses conventional fire inspection carrying out burner hearth flame failure protection; this conventional fire inspection is main to rely on photovalves such as ultraviolet, infrared and visible light that flame intensity and frequency are detected, and judges the situation of single burner flame.The probe visual angle of this class flame detector is fixed, and it is very little, and probe is the position of aiming at flame initial combustion district all the time, because the flame of combustion zone is dynamic change, therefore situation takes place the time wrong report to be arranged, fail to report etc., the commissioning staff can't see that also actual flame changes in addition, and parameter tuning is also very numerous and diverse, seriously influences the safe operation of boiler.
Summary of the invention
In order to solve the existing problem of present boiler furnace safety guard (F S S S); the invention provides a kind of burner hearth intelligent integral flame checking system; this system can import the situation that the flame vision signal is surveyed burner flame; and can export flame status switching value signal according to situation; it is fit to the protection system of various boilers; can make the testing staff see that directly real flame changes by display in addition; can be convenient to use the touch-screen setup parameter; debug easy, the generation that can stop to report by mistake and fail to report situation.
The present invention solves the concrete scheme that its technical matters adopts: this system has one by probe, processor, display, parameter setting device and relay are electrically connected integrated integrated package, the form of this kind integrated package, can avoid probe to separate, institute's transmission distortion that causes and loss, the signal waveform of reservation flame that can be complete to greatest extent with processor; The processor of this system is electrically connected with communication converter, and carries out communication by communication converter and host computer PC and be connected, and forms LAN (Local Area Network); The probe detecting device has the 24V direct supply; Between host computer PC and communication converter and probe detecting device, be connected in series and lays 2 core multiple twin thigh shielded cables, by the detector output signal of popping one's head in to all system units, thereby form an intelligent integral flame checking system.
Its beneficial effect is: this system can import the situation that the flame vision signal is surveyed burner flame; and can export flame status switching value signal according to situation; it is fit to the protection system of various boilers; can make the testing staff see that directly real flame changes by display in addition; can be convenient to use the touch-screen setup parameter; debug easy, the generation that can stop to report by mistake and fail to report situation.
Description of drawings
The invention will be further described below in conjunction with drawings and the embodiments;
Accompanying drawing 1 is a square principle schematic of the present invention;
Accompanying drawing 2 is for illustrating communication converter of the present invention and being connected of host computer PC and probe detecting device schematic diagram;
Among the figure, 1 probe, 2 processors, 3 displays, 4 communication converters, 5 parameter setting devices, 6 relays, the detecting device of 7. popping one's head in, 8 host computer PC, 9 terminal boxes, the bifilar shielded cable of 10,11 cores, 12 communication converters, 13 probe detecting devices.
Embodiment
In Fig. 1,2, this system has one by probe 1, processor 2, display 3, parameter setting device 5 and the integrated integrated package of relay 6 electrical connections, the form of this kind integrated package, can avoid popping one's head in and separate transmission distortion and the loss that is caused, the signal waveform of reservation flame that can be complete to greatest extent with processor; The processor 2 of this system is electrically connected with communication converter 4,12, and carries out communication by communication converter 4,12 with host computer PC 8 and be connected, and forms LAN (Local Area Network); Probe detecting device 7,13 has the 24V direct supply; Between host computer PC 8 and communication converter 4,12 and probe detecting device 7,13, be connected in series and lays 2 core multiple twin thigh shielded cables 10,11, by the detector output signal of popping one's head in to all system units, thereby form an intelligent integral flame checking system.
In Fig. 2, all " communication A " lines are received together, all " communication B " lines are received together, determine on " communication A " and " communication B " correct respective terminal that is connected to converter.
In Fig. 2, cable must be 2 core multiple twin thigh shielded cables, and shielding line is only host computer PC end one place's ground connection, in case ground loop, the specification of arranging cable should directly be shown to determine according to the wiring distance line between host computer and the distal-most end numerically controlled intelligent flame detector.
In the drawings, distal-most end numerically controlled intelligent probe detecting device 7,13 terminal resistance switches must place the NO open position, and all the other terminal resistance switches must place open position (placing NO when dispatching from the factory).
