Description of drawings
Fig. 1 is the modular construction sketch map of the described intelligent boiler control device of the utility model.
The specific embodiment
The specific embodiment one, combination Fig. 1 explain this embodiment, and intelligent boiler control device, this device comprise data acquisition module, protocol conversion module, logical relation processing module and logical relation processing module;
Data acquisition module is connected with protocol conversion module, and it is used to gather the high limit alarm switch amount signal of water level signal, temperature and resistance signal and the output of fuel gas secondary meter of boiler;
Protocol conversion module and logical relation processing module, it is used for the signal of data collecting module collected is carried out transfer of data through the MODBUS485 agreement; Realize the image data between the module and boiler carried out logic control;
The logical relation processing module shows with signal and output module is connected; It is used for the temperature and resistance signal to data collecting module collected; The high limit alarm switch amount signal of the water level signal of boiler and the output of fuel gas secondary meter carries out Treatment Analysis, realizes temperature control, water level control and security control to boiler;
Signal shows and output module is used to receive the collection signal of data acquisition module output and show, judges according to the logic state variation of current system.
The described data acquisition module of this embodiment is RTU, and described signal shows and output module is the industrial flat computer of touch-screen.
The described signal of this embodiment shows and output module is the core of this system; The signal that its acknowledge(ment) signal collecting unit collects is exported various instructions; And show operation information and the system information relevant with control through liquid crystal touch screen; In the various running statuses of LCD screen display device, when working state of system changed, system can note current working state information and carry out logic according to status information and judge.
Concrete running status can comprise:
One, by key text, key frame: press this function key interface and return key frame,
Manually automatically: manually switch with auto state, when manual state down during operation, system does not receive condition such as design temperature to control flame automatically, can directly press one section of control, control is carried out the flame size selection for two sections; When auto state this device of following time can be according to setting the automatic control that shell bound temperature realizes one section fire and two sections fire.
Historical temperature: the historical temperature of record shell temperature, outlet temperature, inlet temperature, inquire about according to the time.
Log: the operation conditions of record boiler, switch stove and fault etc. were inquired about according to the time.
Alarm settings: set upper lower limit value, the return difference setting of shell temperature.
Ann silence: system can cancel audible alarm after when reporting to the police, pressing ventil.
Control one section: control one section flame, control two sections: control two sections flames.
Two, explicit declaration
Outlet temperature: show current outlet temperature; Inlet temperature: show current inlet temperature; Shell temperature: show current shell temperature; Low liquid level warning indication: alarm lamp flicker when boiler water shortage; Combustible gas is reported to the police and is indicated: indicator lamp flicker when combustion gas is leaked to upper limit alarm; One section fire burns indication: one section flame combustion state indication; Two sections fire burns indications: two sections flame combustion state indications;
