The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the dye liquor concentration on-line measuring device of dual-wavelength spectrophotometry has mechanical system, circuit unit, light path system.The device of the utility model adopt two independently monochromator produce the light of two bundle different wave lengths; Promptly use dual-wavelength spectrophotometry; Handle in conjunction with langbobier law and ARM7 processor data; Thereby it is big to eliminate mixing dye liquor phase mutual interference or ambient interferences to a great extent, realizes the measurement of muddy or many components dye liquor concentration.Native system adopts PC control operation mode, and operating personnel do not need very strong professional knowledge and only need on computer interface, carry out some simple parameters settings and just can start this device completion dye liquor concentration surveying work easily.
Before starting this device; Need guarantee that at first sensor signal lines in the circuit unit correctly is connected with signal conditioning circuit, host computer PC correctly is connected through serial ports with slave computer ARM7TDMIS (being the ARM7 processor); Parts such as diffraction grating, plano-concave spherical reflector do not change between damage, each position in the light path system, and selector valve correctly is connected with two-way pump, reservoir, diluent aperture etc. in the SIA system (being the sequential injection system).
After inspection work was accomplished, at first with pump control circuit and signal conditioning circuit energising in drive circuit, slave computer ARM7TDMIS, the SIA system, slave computer ARM7TDMIS was in running status to the operator afterwards, and whole device is in holding state.
Prepare before the operation; The operator need set suitable systematic parameter on the PC interface; The time that stream cleans in the SIA system at first need be set, two-way pump slewing rate, direction transformation frequency and running time are set then, light path system medium wavelength size then is set.Set the preorder preparation of whole system later on of above parameter and accomplish, system just can carry out measurement of concetration.
The operator clicks the " RUN " button, and host computer PC can be sent to order among the slave computer ARM7TDMIS, the corresponding action of command execution that slave computer ARM7TDMIS sends according to PC according to the program that sets in advance, and the course of work of system is following:
At first this device receives the zeroing order that is sent to slave computer ARM7TDMIS by host computer PC; Thereby the rotation of slave computer ARM7TDMIS control step driven by motor sine mechanism is rotated the grating that connects together with sine mechanism, and to a certain degree signal of optical coupler feedback is modulated to zero point to slave computer ARM7TDMIS explanation when turning to.And then host computer PC is sent wavelength and order is set to slave computer ARM7TDMIS, and slave computer ARM7TDMIS calculates according to programming and drives stepper motor and rotate the wavelength that certain step number just can make light path reach setting and penetrate from slit.
Then, host computer PC is sent and is cleaned the stream order of SIA system, the time that slave computer ARM7TDMIS cleans according to command execution.The host computer PC order of sending afterwards is exploitation speed, the order of direction change frequency of pump, and slave computer ARM7TDNMIS is fill order action repeatedly constantly, ceases and desist order or reset command up to occurring.At first sending selector valve that order control opens the SIA system by host computer PC opens it to lead to dye bath one end; Host computer PC is sent to order and is made selector valve turn to dilution one end subsequently; And then push the dye liquor after its dilution to reservoir through two-way pump, flow into the cuvette that flows.When dye liquor dilution back flows into the cuvette that flows; Photoelectric sensor is just started working; Through the continuous acquisition process data of signal conditioning circuit, send to its dye liquor concentration of PC interface display to the data after handling then, concentration range can be reported to the police if dye liquor concentration exceeds setting.Simultaneous temperature working sensor collecting temperature signal; Through sending to slave computer ARM7TDNMIS and host computer PC after the signal conditioning circuit processing; Because SIA system dilution flow rate etc. is brought the hysteresis of time, temperature; This checkout gear can have been accomplished the variation of real-time detectable concentration through setting up the model of temperature, concentration and time, flow velocity.
Carry out and can operate again by reset key when above step appears in system, after each concentration determination was accomplished, system write down automatically and adds up, and statistics can be consulted and used for dyeing scheme in the future provides.
The utility model host computer PC can be connected with the CAN fieldbus, realizes that a PC can measure the concentration of the different dye bath dye liquors in different dyehouses.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection domain of the utility model.
