[0053] The overall concept of the technical solution in this application embodiment is as follows:

[0054] Taro typically only lasts 2-3 days; it spoils easily if left out for too long. Figure 1 As shown, the taro on the left is a normal taro, while the taro on the right is a spoiled taro. It is difficult to distinguish the two with the naked eye alone. Figure 2 As shown, during the secondary processing, workers need to cut the taro to determine whether it has spoiled. Furthermore, despite the large workload, the color of spoiled taro is not always very obvious. Figure 2 (The image on the right shows a cross-section of a spoiled taro.) Workers may also package spoiled taro, which not only causes a huge waste in terms of cost, but may also bring great food safety risks to the company. Example 1

[0055] like Figure 5 As shown in the figure, this embodiment of the present invention provides a method for detecting spoilage of taro, including a first ultrasonic probe and a second ultrasonic probe, specifically including the following steps:

[0056] Step 1: Place the first ultrasonic probe and the second ultrasonic probe into contact with the surface of the areca nut, with the angle between the second ultrasonic probe and the first ultrasonic probe being 180 degrees; the first ultrasonic probe sends ultrasonic waves into the areca nut.

[0057] Step 2: The second ultrasonic probe receives the echo information generated by the ultrasonic waves in the areca nut.

[0058] Step 3: Analyze the echo information and determine whether the echo information contains a penetrating wave;

[0059] Step 4: If the echo information does not contain the penetrating wave, then the taro has spoiled; otherwise, the taro has not spoiled. Example 2

[0060] like Figure 12 As shown, this embodiment provides a method for detecting spoilage of taro, including a first ultrasonic probe and a second ultrasonic probe, specifically including the following steps:

[0061] Step 1: Place the first ultrasonic probe and the second ultrasonic probe into contact with the surface of the areca nut, with the angle between the second ultrasonic probe and the first ultrasonic probe being 90 degrees; the first ultrasonic probe sends ultrasonic waves into the areca nut.

[0062] Step 2: The second ultrasonic probe receives the echo information generated by the ultrasonic waves in the areca nut and obtains the energy corresponding to the echo information;

[0063] Step 3: Determine whether the energy corresponding to the echo information shows an increasing trend, and use this determination to generate the warning information when the transmitted wave shows an increasing trend in the echo information.

[0064] Step 4: If the energy corresponding to the echo information shows an increasing trend, a deterioration warning is issued.

[0065] In another embodiment, determining whether the energy corresponding to the echo information shows an increasing trend specifically includes:

[0066] The echo information is divided according to a first preset duration to obtain multiple sub-echo information;

[0067] Calculate the energy of each of the sub-echo information;

[0068] Based on the energy of multiple sub-echo information, determine whether the energy corresponding to the echo information shows an increasing trend.

[0069] In another embodiment, the moment when the first ultrasonic probe injects ultrasonic waves into the areca nut is set as the start time of the echo information; the start time plus a second preset duration is set as the end time of the echo information; the second preset duration is divided according to the first preset duration to obtain multiple sub-echo information.

[0070] In another embodiment, after obtaining the multiple sub-echo information, the method further includes:

[0071] Multiple sub-echo information are acquired and identified, with the identifiers arranged in ascending order according to the time corresponding to the sub-echo information;

[0072] Determining whether the energy corresponding to the echo information shows an increasing trend based on the energy of multiple sub-echo information includes:

[0073] Obtain the nth energy of the sub-echo information of the nth preset identifier;

[0074] Obtain the (n+1)th energy of the sub-echo information of the (n+1)th preset identifier;

[0075] Determine whether the energy value after multiplying the nth energy by a preset multiplier is less than the (n+1)th energy. If it is less, then it is determined that the energy corresponding to the echo information shows an increasing trend, and the taro has spoiled; otherwise, the taro has not spoiled. Since the first preset duration is very short, if the taro spoils, the energy corresponding to the echo information will show an increasing trend. Example 3

[0076] like Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a taro spoilage detection system 20, including a terminal device 21, a first ultrasonic probe 22, and a second ultrasonic probe 23. The contact surfaces of the first ultrasonic probe 22 and the second ultrasonic probe 23 are coated with a coupling agent. Alternatively, the detection system 20 further includes a water immersion tank 24, in which the taro 10 is immersed. The contact surfaces of the first ultrasonic probe 21 and the second ultrasonic probe 22 are respectively in contact with the surface of the taro 10 in the liquid of the water immersion tank 24. The liquid in the water immersion tank 24 is water. Specifically, the system includes the following steps:

[0077] Step 1: The first ultrasonic probe 22 and the second ultrasonic probe 23 are brought into contact with the surface of the taro 10, and the angle between the second ultrasonic probe 23 and the first ultrasonic probe 22 is 180 degrees; the first ultrasonic probe sends ultrasonic waves into the taro.

[0078] Step 2: The second ultrasonic probe 23 receives the echo information generated by the ultrasonic waves in the areca nut 10;

[0079] Step 3: Analyze the echo information and determine whether the echo information contains a penetrating wave;

[0080] Step 4: If the echo information does not contain the penetrating wave, then the taro has spoiled; otherwise, the taro has not spoiled.

[0081] In some embodiments, the terminal device 21 is used to receive data for judgment; the terminal device 21 may be a computer or a development board with a processing chip. The terminal device 21 only needs to be able to implement the areca nut detection method provided in any embodiment of this application; therefore, this application does not limit the type of terminal device 21.

[0082] like Figure 6 As shown, the terminal device 21 uses a development board with a processing chip. The first ultrasonic probe 22 and the second ultrasonic probe 23 are connected to the surface of the areca nut 10 at a 180-degree angle, allowing the first ultrasonic probe 22 and the second ultrasonic probe 23 to emit signals through the areca nut 10. The terminal device 21 then determines whether the echo information sent by the second ultrasonic probe contains a penetrating wave. For example... Figure 7 and Figure 8 As shown, Figure 7 This is an echo diagram of an unspoiled taro provided in an embodiment of this application. Figure 8 This is an echo diagram of a deteriorated areca nut provided in an embodiment of this application. (Through...) Figure 7 Figure 8 It is known that, under ultrasonic beam transmission, the echo from an unspoiled taro contains a significant penetrating wave. Therefore, when the terminal device resolves the echo information and finds that it does not contain a penetrating wave, a warning message can be generated to confirm that the currently detected taro has spoiled. Example 4

[0083] like Figure 3 , Figure 4 and Figure 12 As shown, this embodiment provides a taro spoilage detection system 20, including a terminal device 21, a first ultrasonic probe 22, and a second ultrasonic probe 23. The contact surfaces of the first ultrasonic probe 22 and the second ultrasonic probe 23 are coated with a coupling agent. Alternatively, the detection system 20 further includes a water immersion tank 24, in which the taro 10 is immersed. The contact surfaces of the first ultrasonic probe 21 and the second ultrasonic probe 22 are respectively in contact with the surface of the taro 10 in the liquid of the water immersion tank 24. The liquid in the water immersion tank 24 is water. Specifically, the system includes the following steps:

[0084] Step 1: The first ultrasonic probe 22 and the second ultrasonic probe 23 are brought into contact with the surface of the taro 10, and the angle between the second ultrasonic probe 23 and the first ultrasonic probe 22 is 90 degrees; the first ultrasonic probe 22 sends ultrasonic waves into the taro 10.

[0085] Step 2: The second ultrasonic probe 23 receives the echo information generated by the ultrasonic wave in the areca nut 10 and obtains the energy corresponding to the echo information;

[0086] Step 3: Determine whether the energy corresponding to the echo information shows an increasing trend, and use this determination to generate the warning information when the transmitted wave shows an increasing trend in the echo information.

[0087] Step 4: If the energy corresponding to the echo information shows an increasing trend, a deterioration warning is issued.

[0088] In another embodiment, determining whether the energy corresponding to the echo information shows an increasing trend specifically includes:

[0089] The echo information is divided according to a first preset duration to obtain multiple sub-echo information;

[0090] Calculate the energy of each of the sub-echo information;

[0091] Based on the energy of multiple sub-echo information, determine whether the energy corresponding to the echo information shows an increasing trend.

[0092] In another embodiment, the moment when the first ultrasonic probe injects ultrasonic waves into the areca nut is set as the start time of the echo information; the start time plus a second preset duration is set as the end time of the echo information; the second preset duration is divided according to the first preset duration to obtain multiple sub-echo information.

[0093] In another embodiment, after obtaining the multiple sub-echo information, the method further includes:

[0094] Multiple sub-echo information are acquired and identified, with the identifiers arranged in ascending order according to the time corresponding to the sub-echo information;

[0095] Determining whether the energy corresponding to the echo information shows an increasing trend based on the energy of multiple sub-echo information includes:

[0096] Obtain the nth energy of the sub-echo information of the nth preset identifier;

[0097] Obtain the (n+1)th energy of the sub-echo information of the (n+1)th preset identifier;

[0098] Determine whether the energy value after multiplying the nth energy by a preset multiplier is less than the (n+1)th energy. If it is less, then it is determined that the energy corresponding to the echo information is increasing, and the taro has spoiled; otherwise, the taro has not spoiled.

[0099] In some embodiments, the terminal device 21 is used to receive data for judgment; the terminal device 21 may be a computer or a development board with a processing chip. The terminal device 21 only needs to be able to implement the areca nut detection method provided in any embodiment of this application; therefore, this application does not limit the type of terminal device 21.

[0100] like Figure 9 As shown, the first and second ultrasonic probes are connected to the surface of the areca nut at a 90-degree angle, allowing the first and second ultrasonic probes to project at an oblique angle through the areca nut. Figure 10 and Figure 11As shown, Figure 10 This is an echo diagram of another undeteriorated taro provided in an embodiment of this application. Figure 11 This is an echo diagram of another type of deteriorated areca nut provided in an embodiment of this application. (Through...) Figure 10 Figure 11 It is known that when ultrasound is projected at a 90-degree angle, the energy of the echo from spoiled taro shows a significant increasing trend. Therefore, when the terminal device detects an increasing energy trend in the echo information, an early warning message can be generated to confirm that the currently detected taro has spoiled.

[0101] The terminal device divides the echo information according to a first preset duration. For example, when the echo information corresponds to a time length of 200ms, the echo information is divided into 20 sub-echo information with a first preset duration of 10ms. By calculating the energy corresponding to the sub-echo information, the changing trend of multiple sub-echo information can be obtained. Then, the terminal device can determine whether the energy corresponding to the echo information is increasing, thereby confirming whether the taro to be detected has spoiled.

[0102] By acquiring the identifiers corresponding to multiple sub-echo information, for example, dividing the 0-200ms echo information into 20 sub-echo information in 10ms increments, the sub-echo information with a time of 0-10ms is identified as 1, the sub-echo information with a time of 10-20ms is identified as 2, and so on, with the sub-echo information with a time of 190-200ms identified as 20. Then, the first energy of the sub-echo information with a first preset identifier can be acquired. For example, in the 20 sub-echo information, if the first preset identifier is set to 5, the sub-echo information with identifier 5 (time of 40-50ms) can be acquired. Then, the second energy of the sub-echo information with a second preset identifier can be acquired. For example, in the 20 sub-echo information, if the first preset identifier is set to 15, the sub-echo information with identifier 10 (time of 90-100ms) can be acquired. By multiplying the first energy by a preset multiplier, such as 1.1, if the energy value of the first energy multiplied by the preset multiplier is still less than the second energy, it can be confirmed that the energy corresponding to the echo information is increasing, and the taro to be detected has spoiled.

[0103] It should be noted that in some embodiments, the preset magnification can be 1.1 or 1.2, and this application does not limit the value of the preset magnification.
