The program circuit of incremental pid algorithm is as shown in Figure 9:
As above, first PID controller calculates inclined difference e (n) to the program circuit of incremental pid algorithm, by difference
Value e (n) calculates Proportional coefficient K P, and then passing ratio COEFFICIENT K p calculates Up、UI、UDFinally pass through U againp、UI、
UDCalculate output △ u (n), update e (n), e (n-1) afterwards and return.
The normal operation circumstances temperature of analyser is 10 DEG C～30 DEG C, it is demonstrated experimentally that identical design temperature
36 DEG C, the ambient temperature contrast of 10 DEG C and 30 DEG C, use air bath thermostatic mode, reactant liquor can be caused
Temperature deviation is more than 3 DEG C, it is impossible to meet the reaction requirement of specific protein reagent, therefore, the balance of reaction tray
Temperature needs to add the temperature-compensating with environmental change, finally makes which kind of ambient temperature no matter reactant liquor be in
Under can stablize on specified temp.
Ambient temperature use experiment calorstat simulated environment temperature realize, calorstat temperature according to 2 DEG C of step-lengths from
10 DEG C are incremented to 30 DEG C, at different ambient temperatures, regulate reaction tray design temperature so that reaction liquid temperature
Spend constant at 36 DEG C, thus draw the relation of ambient temperature and reaction tray design temperature, with 30 DEG C of environment temperature
The reaction tray temperature set when spending is as reference temperature, the reaction tray temperature set with variation of ambient temperature and reference
The difference of temperature is temperature-compensating, thus obtains the relation of temperature-compensating and ambient temperature, as shown in Figure 10.
This attemperating unit, for specific protein analyser reaction tray, uses air bath constant temperature system, uses
PID constant temperature algorithm directly heats reaction tray kerve, the then air around reacting by heating dish, and air heats indirectly
The temperature of liquid in reaction cup, reaction cup both sides have solid to depend on, play insulation effect, when kerve temperature is put down
Weighing apparatus is after certain specified temp, and the temperature of reactant liquor balances the most therewith in certain temperature.But, along with environment
The change of temperature, reacting liquid temperature can deviate default temperature, have impact on the test knot of specific protein analyser
Really precision.Therefore this temperature control system adds the temperature-compensating with variation of ambient temperature, in different environment temperature
Under degree, by the temperature that sets at certain plus corresponding temperature-compensating so that reactant liquor is stable at Qi Te
Fixed temperature.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
