Embodiment Construction

[0018] like figure 1 As shown, the present invention includes four components: a sound sensor 1 , a sensor interface circuit module 2 , a microprocessor 3 and a display hardware module 4 .

[0019] When the device is working, the sound sensor 1 is placed in the external auditory canal of the relevant person, collects the sound signal generated by chewing and swallowing and reaches the external auditory canal through bone conduction, and transmits the obtained sound signal to the microcomputer through the sensor interface circuit module 2. processor 3. The sound signal given by the sound sensor 1 is a voltage signal of millivolt level.

[0020] The sensor interface circuit module 2 realizes the amplification and conversion of the sound sensor signal, so as to meet the signal reading requirements of the microprocessor 3 . The sensor interface circuit module 2 includes a voltage amplifier circuit and an AD conversion circuit. The voltage amplifier circuit amplifies the millivol...

Abstract

The invention relates to an eating habit monitoring device, which comprises a sound sensor, a sensor interface circuit module, a microprocessor and a display hardware module. The microprocessor comprises a sound signal acquiring module, a signal pretreating module, a signal feature extracting module, a signal feature classifying module, an eating habit analyzing and calculating module and a display software module, and is implemented by the following steps of: when a person eats, continuously acquiring a sound signal in an external auditory canal by using the sound sensor arranged in the external auditory canal; pretreating the sound signal; performing feature extraction on the pretreated sound signal; classifying feature values, and distinguishing swallowing signals and chewing signals and time corresponding to the swallowing signals and the chewing signals; calculating eating habit index values of the person, including total swallowing times, average swallowing times in unit time, and the average chewing time and average chewing times of each time of swallowing; and displaying the habit index values. By the eating habit monitoring device, the eating habit of the person can be analyzed, calculated and displayed, and body health is benefited.

Description

technical field [0001] The patent of the present invention relates to an eating habit monitoring device, in particular to an eating habit monitoring device based on the sound signal of the external auditory canal. Background technique [0002] For a long time, many people generally have problems such as fast eating and less chewing when eating, and due to the temptation of food, the amount of food in each meal is often too much. These bad eating habits, such as eating too fast and chewing too few times, obviously have adverse effects on human health, and are one of the incentives for many people's stomach problems, obesity, excessive weight loss and other diseases. Correcting bad eating habits as much as possible is the goal that many people pursue in their lives. [0003] In addition to vigorously promoting the concept of "chewing slowly", you can also start from technical means and use the help of auxiliary equipment to achieve the purpose of developing healthy eating hab...
