S301, obtains the operating condition signal of described rotary kiln.
S302, according to described operating condition signal, judges whether described rotary kiln shuts down.
Master control system due to backstage is responsible for the running controlling rotary kiln, so in embodiments of the present invention, can obtain the operating condition signal backhauling kiln, and then judge whether rotary kiln shuts down from master control system there.
Shown in Figure 4, in the present embodiment or the present invention's some other embodiments, described method can also comprise:
Make before described temperature measuring equipment enters park mode:
S401, the temperature data gathered when record shuts down.
S402, at interval of the first preset duration, whether the difference of the temperature data gathered when judging current gathered temperature data and shut down exceedes first threshold; If exceed described first threshold, then allow to perform to make described temperature measuring equipment enter the step of park mode.
This is because consider in the practical work process of rotary kiln, due to a variety of causes, such as short time maintenance etc., there will be the of short duration situation about shutting down of rotary kiln.Now because rotary kiln will operate very soon again, therefore can enter park mode without the need to making rotary kiln, pattern also can be avoided to switch as responsive.And if reduced first threshold, then illustrate now rotary kiln the long period stopped work, can be judged as YES really to stop kiln, temperature measuring equipment therefore can be made to enter park mode.
The size of first threshold according to the size of the actual scene sets itself first threshold of rotary kiln, such as, can be set to 10 DEG C by technical staff.
In addition, in the present embodiment or the present invention's some other embodiments, described method can also comprise:
When described temperature measuring equipment is in park mode, at interval of the 3rd preset duration, judge whether described rotary kiln operates, if described rotary kiln operates, then make described temperature measuring equipment enter normal mode of operation.

Fig. 5 is the electricity-saving control method flow chart of a kind of temperature measuring equipment according to an exemplary embodiment.Shown in Figure 5, the method can comprise the following steps:
Before outwards sending described temperature data:
S501, calculates the difference of current gathered temperature data and the last temperature data gathered.
S502, judges whether described difference is greater than Second Threshold.
S503, if described difference is greater than Second Threshold, then allows outwards to send described temperature data; Otherwise do not allow outwards to send described temperature data.
Comparing power consumption owing to wirelessly sending data, so in order to reduce temperature measuring equipment power consumption further, when it is in mode of operation, data transmission times can be reduced as much as possible.In the present embodiment, whether can determine whether more greatly to need outwards to send data by the change compared with the last time of current gathered temperature data, if change is little, namely difference is not more than Second Threshold, then illustrate that the temperature fluctuation of rotary kiln is less, master control system still can adopt the last temperature data sent to control rotary kiln, so temperature measuring equipment need not send temperature data again.And when described difference is greater than Second Threshold, illustrate that the temperature fluctuation of rotary kiln is comparatively large, current gathered temperature data need be sent, with the situation making master control system know rotary kiln in time.In addition, it is easily understood that above-mentioned difference is an absolute value.
Technical staff can according to the concrete scene of rotary kiln the size of sets itself Second Threshold, such as, 2 DEG C can be set to.

Whenever running into the situation always outwards not sending described temperature data in the second preset duration, when the second preset duration timing is arrived, then described temperature measuring equipment is made outwards to send current gathered temperature data.
This is because, in actual applications, if kiln temperature stablizes ripple disable, when judging whether to need to send temperature data according to the difference of current temperature data and last temperature data, likely there will be the phenomenon that temperature measuring equipment does not send gathered temperature data for a long time, namely temperature signal is in the state of Transmission for a long time.But the fault due to temperature measuring equipment also may cause the interruption of transmission, so now staff may be difficult to determine whether the end is the Transmission caused due to the fault of temperature measuring equipment.
So a timer t can be arranged, when the timing of timer t is more than or equal to the second preset duration, then activate the process of transmitting of a temperature signal, make temperature measuring equipment send current gathered temperature data, then timer t reset and restart timing.If during timer t timing, when temperature measuring equipment sent the temperature data gathered, also needed timer t is reset and reclocking.
Like this, if when temperature measuring equipment did not send the temperature data gathered all the time more than the second preset duration, then can judge that fault has appearred in temperature measuring equipment.
Technical staff according to the size of field condition sets itself second preset duration of rotary kiln, such as, can be set to 30 minutes.
