The spectrum analysis terminal comprises an audio receiver (22), a filter (23), an audio converter (26), and an audio spectrum output device connect in sequence for signal transmissions. Owing to the sound sensor (21) configured to collect audio signal from the pot body (11) of the cooking pot, a user can hear a degree of doneness of food and gain knowledge of cooking status of the food in the pot without opening the pot. The signal collected by the sound sensor (21) is received by the spectrum analysis terminal, and is then subject to noise filtering performed by the filter (23) and conversion to form an audio spectrum segment. The audio spectrum segment can be displayed in various audible or visible formats so as to provide a more direct sound or view for understanding the cooking status within the pot, thereby offering an ergonomic means of assessing and determining a degree of doneness of food. A culinary mapping and evaluation method is also provided which allows visual understanding of cooking status within a pot and can be used to evaluate a degree of doneness of food. ## Claims ### Claim 1 A culinary mapping tool for detecting cooking status in a pot, comprising a sound sensor capable of directly or indirectly collecting an audio signal within the pot, and a spectrum analysis terminal for receiving the audio signal from the sound sensor, wherein the spectrum analysis terminal comprises an audio receiver, a filter, an audio converter, and an audio spectrum output device, connected in sequence for signal transmission. ### Claim 2 (depends on 1) The culinary mapping tool of claim 1, wherein the audio converter is connected to a comparison processor comprising a comparison unit and an output control unit. ### Claim 3 (depends on 1) The culinary mapping tool of claim 1, wherein the sound sensor collects the audio signal conducted through solid material or is directly in contact with a body or lid of the pot. ### Claim 4 (depends on 1) The culinary mapping tool of claim 1, wherein the sound sensor is a microphone or a microelectromechanical sensor. ### Claim 5 (depends on 1) The culinary mapping tool of claim 1, wherein the sound sensor is a laser monitor comprising a laser transmitter, and a photoelectric detector for receiving a laser transmission signal and converting it into an electrical signal. ### Claim 6 (depends on 1) The culinary mapping tool of claim 1, wherein the spectrum analysis terminal is a computer, a smartphone, a smartwatch or a dedicated terminal device that is preloaded with an analysis software. ### Claim 7 (depends on 1) The culinary mapping tool of claim 1, wherein the spectrum analysis terminal further comprises a warning indicator connected to the audio converter, and the warning indicator comprises at least one of a sound warning unit, a visual flashing warning unit, and a vibration warning unit. ### Claim 8 (depends on 1) The culinary mapping tool of claim 1, wherein the spectrum analysis terminal is connected with the audio converter and further comprises a circuit breaker for controlling the pot to cut off heat source, and wherein the spectrum analysis terminal further comprises a storage unit connected with the audio converter. ### Claim 9 (depends on 1) The culinary mapping tool of claim 1, wherein the audio spectrum output device is a display that presents sound spectrum or a lamp that reflects status of sound spectrum by color and/or brightness. ### Claim 10 A culinary mapping and evaluation method, comprising: S1. installing a sound sensor by direct contacting or conductively contacting the sound sensor in a body or a lid of a cooking pot, or installing a laser monitor against a body of a cooking pot as a non-contact type of sound sensor, and the sound sensor transmitting collected audio signal to a spectrum analysis terminal; and S2. filtering environmental noises through a filter, and converting audio signals over a continuous time period into audio spectrum segments which are visually displayed or restored to sound and played by a loudspeaker, whereby food status and degree of cooking in the pot is determined according to a relationship between an audio spectrum segment and food status. ### Claim 11 (depends on 10) The culinary mapping and evaluation method of claim 10, wherein the spectrum analysis terminal is equipped with a timer, and time signal output of the timer is taken as a culinary evaluation parameter. ### Claim 12 (depends on 10) The culinary mapping and evaluation method of claim 10, wherein the spectrum analysis terminal is inbuilt with a culinary experience database, or linked to an Internet experience sharing database, and wherein in step S2, an empirical value and a feedback audio signal are presented in a same visible format and compared, and a warning is generated in audible or visible format at the moment when the value and the signal coincide. ### Claim 13 (depends on 10) The culinary mapping and evaluation method of claim 10, wherein an alarm signal is emitted when the feedback audio signal reaches a dry pot threshold or an audio generated by spilled liquid in contact with a high temperature object is detected. ### Claim 14 (depends on 13) The culinary mapping and evaluation method of claim 13, wherein an intervention signal is emitted simultaneously to trigger cutting off the heating source or an anti-scorching intervention action of the cooking pot. ### Claim 15 (depends on 10) The culinary mapping and evaluation method of claim 10, wherein the audio spectrum segment corresponding to a specific process of cooking of a designated food is recorded and stored as a standard spectrum segment, and the standard spectrum segment so stored or otherwise introduced externally is extracted, based on which a control signal is output to regulate the flux of heating source to allow real-time audio spectrum to coincide with the standard spectrum segment.
