In the situation that the temperature control thermistor does not access, utilize circuit characteristic, revise temperature and control true form, making the temperature control requirement is [FA with 2 16 system temperature control true form numeric representations of thermistor, FB], well heater is in closed condition because being provided with lower temperature value, thereby has intactly detected the test of well heater open and close functions.
Preferably, step 2 is specially: manage by number method that computing machine annotates number the threshold value of temperature control thermistor is arranged, and it is slightly higher than the actual thermally sensitive temperature scope recorded that the temperature control scope is set, by actual acquisition to thermistor temp value and setting value compare, when the temperature value collected, during lower than the low-temperature values of design temperature, well heater is opened; When the temperature value collected, during higher than the high temperature values of design temperature, well heater cuts out.
In the situation that thermistor access closed loop temperature control, revise the setting of temperature control threshold values, make set temperature control scope slightly higher than the actual thermally sensitive temperature scope recorded, if temperature controlling function is normal, well heater is started working, temperature starts to rise, when temperature is elevated to a certain degree, while having surpassed set temperature upper limit, well heater just has been in off-state, now temperature will descend, thereby has verified automatic temperature-adjusting control function.

The accompanying drawing explanation
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present invention will become:
The principle schematic of the method for testing that Fig. 1 is the temperature automatically controlled function of a kind of fast detecting of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art further to understand the present invention, but not limit in any form the present invention.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make some distortion and improvement.These all belong to protection scope of the present invention.
Refer to Fig. 1, the method for testing of the temperature automatically controlled function of a kind of fast detecting comprises the following steps:
Step 1: in the situation that thermistor does not access the temperature control loop: upload the temperature control threshold value to number pipe computing machine by annotating number, the temperature control threshold value when well heater opening/closing is set, observe whether opening/closing of well heater.
Whether step 11: the temperature control threshold value when well heater being set opening is [FA, FB], observe well heater and open;
Whether step 12: the temperature control threshold value when well heater being set closing is [F0, F8], observe well heater and close.
In the electrical testing process of whole star, the function that temperature is controlled software realizes being accomplished as early as possible test, can not complete performance test else if on time, ability exposure problem in whole star thermal vacuum test, will affect the effect of test, thereby have influence on the development effort of model.
Due to the restriction of condition, early stage in test, the thermistor of temperature control is not installed, the object that the temperature control loop does not have closed loop to get involved therefore be difficult to the testing heater function normally whether.Generally, when thermistor does not access, can think the resistance infinity, according to the characteristic (along with the rising of temperature, the resistance of thermistor reduces gradually) of thermistor, now corresponding temperature should be utmost point low value, according to the temperature control strategy, the state that now well heater is out.The function of closing in order to detect well heater, utilized especially the high-end numerical value of 2 16 system temperature control true forms of thermistor, according to circuit characteristic, when thermistor does not access, its former code value is F9, when we revise the temperature control threshold value for [FA, FB] time, be not difficult to find out, now well heater is in closed condition because being provided with lower temperature value, thereby has intactly detected the test of well heater open and close functions.
Step 2: in the situation that thermistor access temperature control loop: by annotating number, upload the temperature control threshold value to number pipe computing machine, temperature control threshold value when well heater being set opening is a little more than the actual temperature measured value, whether observe well heater opens, and observe when temperature is elevated to over the temperature control threshold value, whether well heater closes.
Managing by number method that computing machine annotates number is arranged the threshold value of temperature control thermistor, and it is slightly higher than the actual thermally sensitive temperature scope recorded that the temperature control scope is set, by actual acquisition to thermistor temp value and setting value compare, when the temperature value collected, during lower than the low-temperature values of design temperature, well heater is opened; When the temperature value collected, during higher than the high temperature values of design temperature, well heater cuts out.
In the situation that thermistor access closed loop temperature control, due to the environment temperature in the electrical testing situation generally near room temperature, in most cases may fall in the temperature range of actual temperature control, a kind of closed condition often only appears in the state of its well heater, the setting of now utilization modification temperature control threshold value completes the test of open and close function, can more intactly detect the function of temperature control.As the temperature temperature control scope of certain stand-alone device is [5 ℃, 25 ℃], and actual temperature control thermistor temp is 20 ℃, can find out, at this temperature, well heater is closed condition, the state of opening in order to detect well heater, can change the temperature control threshold value and be [21 ℃, 22 ℃], well heater just can be in open mode like this, and raises while surpassing 22 ℃ when the temperature of the temperature controlling instruments temperature of opening along with well heater, well heater there will be the state of disconnection, thus can detect temperature controlling function normally whether.
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present invention.
