Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, be the process flow diagram of an embodiment of a kind of temperature rush compensation method of the present invention;
In the temperature control equipment of reality, can actual not contact between sensor and heater block, have certain space both, when causing the temperature rising of heater block when heater block begins to heat, due to and sensor between the space that exists cause the temperature of sensor senses lower than the actual temperature of heater block, be exactly the temperature value that self obtains and sensor sends to the temperature value of processing module; So the temperature value that processing module is obtained can not actually embody the actual temperature of heater block.
The embodiment of the present invention adopts after processing module gets the temperature value of sensor transmission, whether judges temperature lower than threshold value, described temperature value is added that a temperature compensation value is as the actual temperature value of the heater block of reality when lower than threshold value.
Step S101, heater block start, sensor obtains temperature value;
When heater block was started working heating, temperature began to rise gradually; Sensor obtains the test point temperature value, this moment, the temperature due to the test point that sensor obtains not was the temperature value of the heater block of reality, the temperature of test point can be lower than the temperature of heater block when heater block has just begun to start shooting heating, and the temperature value that sensor obtains also can be lower than the actual temperature value of heater block.
Step S102, sensor send described temperature value to processing module;
Sensor is converted to electric signal with the temperature value of test point, and sends described electric signal to processing module.
Step S103, the described temperature value of processing module contrast and the warm threshold value of rushing of presetting;
After processing module is obtained described temperature value, compare with the warm threshold value of rushing of presetting;
Carry out the temperature rush compensation step during lower than described punching temperature threshold value when described temperature value.
During greater than or equal to described punching temperature threshold value, can not take temperature rush compensation when described temperature value.
Step S104, processing module add that with described temperature value default temperature rush compensation value exports as measured value.
Lower than default when rushing warm threshold value, processing module adds that with described temperature value default temperature rush compensation value exports as measured value when described temperature value; Concrete, described temperature rush compensation value is successively decreased in time, and described temperature rush compensation value rate of decline increases progressively in time.Below adopt formula that temperature rush compensation is described further:
T=T1+ Δ T; Described T1 is the temperature value that sensor sends to processing module, Δ T temperature rush compensation value, and described T is the measured value of actual output.

t＝ΔT’/d
The temperature compensation value of described Δ T ' for calculating last time, d is proportionality constant, can regulate according to actual conditions.
Δ T initial value=T1/b
Described b is proportionality constant, can regulate according to actual conditions.
Described processing module reaches for the first time at the described temperature value that obtains and begins to reduce the temperature rush compensation value after rushing warm threshold value (namely first punching), accelerates gradually according to the numerical value rate of decline of described temperature rush compensation value, is decremented to 0 always, withdraws from temperature rush compensation.
When being in the temperature rush compensation state, output temperature is that the temperature value that sensor sends adds the temperature rush compensation value, and after temperature rush compensation finished, the temperature value that heater block surface temperature and sensor obtain was synchronous, and processing module stops temperature rush compensation.
Concrete, the temperature compensation value change curve is seen the N line of Fig. 2, the temperature rush compensation value diminishes gradually; The temperature value M line of the cumulative upper temperature-sensing element of temperature rush compensation value namely finally forms the K line in Fig. 2, thereby eliminates the phenomenon of punching temperature.
Further, when the temperature rush compensation method that adopts the present embodiment to provide carries out temperature control, carry out reference as actual temperature and control whether needs heat according to the temperature compensation value of initial setting temperature and calculating, after reaching design temperature for the first time, actual temperature begins to reduce temperature compensation value, accelerate gradually according to the numerical value rate of decline of temperature compensation value, be decremented to 0 always, withdraw from and rush temperature state, enter normal temperature control (whether needs continue heating namely to carry out reference according to the sensor temperature that gets).Consult Fig. 3.
When being in when rushing temperature state, design temperature is that the initial setting temperature adds temperature compensation value, and after the punching temperature finished, heater block surface temperature and sensor temperature were synchronous, enter normal temperature control, namely controlled temperature according to the initial setting temperature.
After the embodiment of the present invention adopts and gets the sensor senses temperature, after if described sensor senses temperature adds a temperature rush compensation value during lower than preset value, as the output of heater block temperature value, made up the difference of sensor senses temperature and actual heater block temperature.
