The utility model discloses the real-time measurement of the responsible temperature of well main control part (control mainboard) and the acceleration signal who judges that angle measuring instrument provides to whether the decision screen needs to change rotatory demonstration. The display part is mainly responsible for outputting numerical values, and is convenient for people to look up. The angle measurement part is responsible for measuring the angle of the current product.
Generally, an automatic rotating screen display food thermometer (hereinafter also simply referred to as "thermometer") is physically designed as an autonomous device with its own battery, the thermometer having a front side and a back side, the front side having a real time display screen for displaying temperature, wherein the display screen number of the thermometer is designed to be switched between display angles from 0-90 degrees-180 degrees-270 degrees-360 degrees, according to the functions as follows:
in general, the way in which the thermometer switches the display angle is based on the use of 3-axis acceleration sensors (X-axis, Y-axis and Z-axis) built into the thermometer to obtain separate acceleration signals for each of these 3 axes, which are compared by a processor (MCU-master control unit) with the corresponding idle acceleration signals. These angular acceleration signals are the previously recorded acceleration signals at each rest angle for a representative selected thermometer. Thus, a common threshold is determined, and for any thermometer the following is true.
a) By exceeding a common threshold in the axes, the use status of the thermometer can be determined, thereby determining the angle of the thermometer display.
b) If the acceleration signals on these axes are substantially coincident with the rotational acceleration signals, it can be determined that the thermometer is at rest.
And adjusting the display value of the numerical value on the screen after the temperature measurement of the thermometer to be displayed from each angle to the front 0 angle according to the comparison result.
Specifically, the above comparison is performed using the parameters of the acceleration signal. Therefore, a predetermined acceleration signal for each of the 3 axes is continuously sampled and determined by the amplitude (Amp) of the signal. These parameters are parameters for comparison with a predetermined common threshold, i.e. with a respective predetermined common threshold for the amplitude (Amp) of each of the 3 axes.
Therefore, no further signal processing is performed on the established acceleration signal.
The thermometer includes a 3-axis acceleration sensor that provides separate sensed acceleration signals for each of the 3 axes (X, Y and Z axes). The single chip microcomputer judges the actual use state and the screen angle state of the thermometer according to the detected signals, and changes the view on the display screen of the thermometer.
Here, it is to be understood that the signal from the acceleration sensor may be understood to represent "the actual relative movement state of the thermometer".
The thermometer switches the displayed view on the thermometer based on a comparison of the detected acceleration signal to a common idle threshold.
The measurement results are obtained as separate detected acceleration signals for each of the three axes (X, Y and Z), without filtering out subsequent signals according to direction, in particular the thermometer is therefore not designed to unconditionally measure a consistent direction.
The measurement in the thermometer is carried out continuously and therefore not within a defined time frame.
It can also be considered that the sampled acceleration signal represents the acceleration in the screen angle direction of the thermometer, i.e. in the three axis direction.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
