Embodiment 1

[0012] figure 1 It is a structural schematic diagram of a mobile phone with a weighing function according to an embodiment of the present invention. Such as figure 1 As shown, the mobile phone includes a display screen 11 and a microcontroller 12 connected to each other, and also includes a weight sensor 13 connected to the microcontroller 12, wherein:

[0013] The weight sensor 13 is used to generate an electrical signal according to the weight of the object to be measured, and send the electrical signal to the microcontroller;

[0014] The microcontroller 12 is used to process the electrical signal received from the weight sensor 13 to generate a digital weight signal, and control the display screen 11 to display the digital weight signal.

[0015] Specifically, any weight sensor in the prior art may be used as the weight sensor for sensing the weight of an object and converting it into an electrical signal for output. Depending on the type of weight sensor and the locati...

Embodiment 2

[0019] On the basis of the first embodiment above, the display screen is a resistive touch screen, including a first surface and a second surface. When the first surface bears the object to be measured, the resistive touch screen generates a The deformation corresponding to the weight of ;

[0020] The weight sensor is a pressure sensor, which is arranged on the second surface of the resistive touch screen, and is used to acquire the deformation generated when the resistive touch screen bears the object to be measured on the first surface, and generate a The electrical signal corresponding to the deformation.

[0021] Specifically, for the existing resistive touch screen, the user operation is sensed through the pressure exerted by the finger or other objects on the touch screen, which has better pressure conductivity. When the first surface of the resistive touch screen (that is, the surface of the mobile phone display facing the user) is used to carry the object to be measu...

Embodiment 3

[0043] On the basis of any of the above embodiments, the mobile phone also includes:

[0044] A piezoelectric vibration measuring film, the piezoelectric vibration measuring film is pasted on the first surface of the display screen, and wirelessly connected with the microcontroller, for when the object to be measured passes through the piezoelectric vibration measuring film When placed on the first surface of the display screen, obtain a vibration signal indicating the vibration amplitude of the display screen, and transmit the vibration signal to the microcontroller;

[0045] Correspondingly, the microcontroller is further configured to send an alarm signal if it is determined that the vibration signal exceeds a preset alarm threshold.

[0046] Specifically, the piezoelectric vibrating film (such as a polymer piezoelectric vibrating film) is pasted on the display screen of the mobile phone to sense the vibration emitted when the display screen is pressed, convert the vibratio...

Abstract

The invention provides a mobile phone with a weighing function, which comprises a display and a microcontroller that are mutually connected. The mobile phone is characterized by also comprising a weight sensor connected with the microcontroller, wherein the weight sensor is used for generating an electric signal according to the weight of an object to be measured, and sending the electric signal to the microcontroller; and the microcontroller is used for processing the electric signal received by the weight sensor, generating a digital weight signal and controlling the display screen to display the digital weight signal.

Description

technical field [0001] The invention relates to signal processing technology, in particular to a mobile phone with a weighing function, which belongs to the field of electronic technology. Background technique [0002] With the great progress of micro-processing technology and sensing technology, mobile phones have been widely used in people's life and work, and the functions realized are more and more diversified. However, the current mobile phone functions usually focus on the improvement of the wireless communication field, such as realizing the automatic positioning and navigation functions of the mobile phone. [0003] Mobile phones have gradually become a necessity in people's lives, and people have a wider demand for mobile phone functions to meet the needs of daily life. Among them, the demand for weighing with mobile phones is particularly urgent. Therefore, how to use mobile phones to realize electronic weighing is a very meaningful research topic. All current mo...
