Baud rate adjustment device and method and cooking utensil

Abstract

The invention provides a Baud rate adjustment device and a Baud rate adjustment method which are used for a cooking utensil. The Baud rate adjustment device comprises a monitoring unit for monitoring communication data transmitted by the cooking utensil; a judgment unit for judging whether the communication of the cooking utensil is normal according to the communication data; and a processing unit for adjusting the Baud rate of the cooking utensil so as to enable the communication of the cooking utensil to be normal when the communication of the cooking utensil is judged to be abnormal. Through the technical scheme of the invention, when the cooking utensil cannot have normal communication due to the generation of relatively-large clock deviation, the cooking utensil can retrieve normal communication automatically through self-adaptive Baud rate adjustment, thereby guaranteeing the correctness of the communication data.

Description

technical field [0001] The present invention relates to the field of baud rate technology, in particular to a baud rate adjustment device, a baud rate adjustment method and a cooking utensil. Background technique [0002] In order to save costs and reduce peripheral electronic components, many MCUs (Micro Control Units, micro processing units) use RC (resistor-capacitor) oscillators that can be integrated inside to replace external clock generation circuits (such as ceramic oscillators, crystal oscillators, etc. ), and in general, the clock frequency generated by this oscillator can make the system work normally. However, when the operating environment is harsh (such as high temperature, ultra-low temperature), the RC oscillator will have a large drift, causing the clock deviation of the system to exceed the system's fault tolerance range, which in turn causes the baud rate of the system to deviate from the inherent baud rate, making There are many errors in system transmis...

Problems solved by technology

However, when the operating environment is harsh (such as high temperature, ultra-low temperature), the RC oscillator will have a large drift, causing the clock deviation of the system to exceed the system's fault tolerance range, which in turn causes the baud rate of the system to deviate from the inherent baud rate, making The system transmits communication data and generates many errors

[0003] However, since the baud rate of the existing system is fixed, when the RC oscillator produces a large clock deviation, the baud rate of the system cannot be adaptively adjusted. When the clock error occurs, the system cannot automatically restore normal communication or even go out of control
