The user can revise the report cycle of data as required, and the time that data report, shorter then corresponding power consumption was also just high more, thus can satisfy under the prerequisite of system requirements, prolong as far as possible data on call time and reduce power consumption; The temperature acquisition variable period
4) dormancy mechanism in employing cycle
Processor module will get into into dormant state after accomplishing corresponding temperature acquisition and data transmission, only remains with real-time clock work, reduces the power consumption of processor module with this;
5) processor module is closed peripheral circuit when dormancy
The power supply of temperature sensor, the detection of battery electric quantity all are to be controlled by triode; When need not carrying out temperature acquisition with the dump of temperature sensor; Same battery electric quantity module is also cut off its power supply in the time need not carrying out the battery electric quantity collection also by the control of triode type;
3, the variable mode of operation of temperature acquisition cycle and data transmitting period
It periodically can manually be formulated or regulate voluntarily in this patent; When being in automatic adjusting pattern; The temperature acquisition cycle can be adjusted according to the temperature of testee automatically; In the temperature range of safety,, and when detecting temperature value and reach fence coverage, then improve the frequency of its collection with slower frequency collection temperature value; Wherein, the user can be provided with safe temperature range voluntarily;
4, battery electric quantity measuring ability
This patent provides the function of battery voltage detection, the periodic measurement battery voltage value, and this magnitude of voltage sent the data to the external data collecting device with the mode that initiatively reports.External wireless device can in time obtain the battery electric quantity of temperature label to change timely.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
