BACKGROUND

[0002] Roast meat is a dish with unique flavor and is widely loved by people. However, the firewood needs to be accurately grasped during the roasting process of meat, and therefore the technical and experience requirements for roasting are relatively high. In order to reduce the difficulty of roasting meat, a food temperature probe is usually configured during roasting to monitor the temperature inside the roast meat.

[0003] The food temperature probe is usually configured with a charging device, and the data transmission between the food temperature probe and the charging device can be but is not limited to the functions of state monitoring, data recording and analysis, device configuration and update, user interaction and feedback of the device.

[0004] In some related technologies, the food temperature probe uses an automatic start-up broadcast mode to interact with the charging device to ensure that the charging device can effectively and accurately bind with the probe to establish a wireless communication connection. However, if there are too many broadcast signals in a certain wireless communication (such as Bluetooth 2.4 GHz) frequency band around, the signals in the same frequency band may be interfered, and misbinding and dead machine phenomena are likely to occur during the screening stage of the broadcast signal in the charging device. Therefore, how to improve the communication stability in the information interaction process between the food temperature probe and the charging device has become a problem to be solved. SUMMARY

Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0064] Please see Figure 1 One embodiment of this application provides a food temperature probe information interaction system, which includes a food temperature probe 10 and a charging device 20 capable of charging the food temperature probe 10.

[0065] The food temperature probe 10 is used to detect the internal temperature of food. The food temperature probe 10 is also used to communicate with a mobile terminal to transmit relevant temperature data. Users can understand the internal temperature of food based on the relevant temperature data displayed on the mobile terminal to determine whether the food is cooked.

[0066] Specifically, the charging device 20 is used to acquire the detection signal generated by the food temperature probe 10 being electrically connected to the charging device 20, and to send an interaction signal to the food temperature probe 10 based on the detection signal; the food temperature probe 10 is used to send a feedback signal to the charging device 20 based on the interaction signal; the charging device 20 is also used to bind to the food temperature probe 10 based on the feedback signal, so that the charging device 20 can communicate with the food temperature probe 10.

[0067] The charging device 20 can not only charge the food temperature probe 10, but also serve as a relay station between the food temperature probe 10 and the mobile terminal. In this case, the food temperature probe 10 communicates with the mobile terminal through the charging device 20. The food temperature probe 10 can first send a wireless signal to the charging device 20, and the charging device 20 sends the wireless signal to the mobile terminal, so that the user can understand the temperature inside the food according to the relevant temperature data displayed on the mobile terminal. Conversely, the mobile terminal can also send a wireless signal to the charging device 20, and the charging device 20 sends the wireless signal to the food temperature probe 10, so that the food temperature probe 10 performs corresponding operations (such as changing the cooking mode of the food temperature probe 10, which can but not limited to have "roast beef mode", "roast lamb mode" and "roast fish mode" and the like) according to the wireless signal. As a relay station, the charging device 20 can process the received signal, eliminate some interference and noise, and improve the clarity and integrity of the signal, so that the mobile terminal can more accurately receive the data sent by the food temperature probe 10. As a relay station, the charging device 20 can be placed in a relatively appropriate position to avoid these interference sources and shields, and ensure smooth signal transmission between the food temperature probe 10 and the mobile terminal. As a relay station, the food temperature probe 10 only needs to communicate with the charging device 20 at close range, which can simplify the design, reduce cost and power consumption, and also help to reduce the size of the food temperature probe 10, making it more convenient to use and insert into food.

[0068] Specifically, the food temperature probe 10 can include a first electrical connection end 12. The first electrical connection end 12 serves as a functional interface of the food temperature probe 10. Specifically, the first electrical connection end 12 can be used as a data transmission interface for data transmission on one hand, and as a charging interface for charging connection on the other hand.

[0069] The charging device 20 can include a second electrical connection end 22. The second electrical connection end 22 serves as a functional interface of the charging device 20. The second electrical connection end 22 can be used as a data transmission interface for data transmission on one hand, and as a charging interface for charging connection when charging the food temperature probe 10 on the other hand.

[0070] When the food temperature probe 10 is in electrical connection with the charging device 20, the first electrical connection end 12 of the food temperature probe 10 is in contact with the second electrical connection end 22 of the charging device 20. At this time, if the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 are used as a data transmission interface, data transmission between the food temperature probe 10 and the charging device 20 can be realized. At this time, if the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 are used as a charging interface, the food temperature probe 10 can obtain electrical energy from the charging device 20 for charging. When the food temperature probe 10 is in electrical disconnection with the charging device 20, the first electrical connection end 12 of the food temperature probe 10 is spaced apart from (i.e., not in contact with) the second electrical connection end 22 of the charging device 20. At this time, neither data transmission between the food temperature probe 10 and the charging device 20 nor the food temperature probe 10 obtaining electrical energy from the charging device 20 for charging can be realized.

[0071] As shown in FIG. 1, the charging device 20 can include a box body 21, and the second electrical connection end 22 can be disposed on the box body 21. The specific structure of the box body 21 is not limited here, and a designer can reasonably design according to actual needs. Figure 2

[0072] In some embodiments, the box body 21 has a receiving groove for accommodating the food temperature probe 10, and the food temperature probe 10 can be detachably arranged in the receiving groove of the box body 21. When a user needs to use the food temperature probe 10 to detect the temperature of food, the user can take out the food temperature probe 10 from the receiving groove of the box body 21. When the user does not need to use the food temperature probe 10 to detect the temperature of food (i.e., the food temperature probe 10 is idle), the user can put the food temperature probe 10 into the receiving groove of the box body 21 to store the food temperature probe 10, thereby avoiding loss of the food temperature probe 10.

[0073] As described above, the second electrical connection end 22 is disposed on the box body 21. The specific connection manner between the second electrical connection end 22 and the box body 21 is not limited here, and a designer can reasonably design according to actual needs. For example, the second electrical connection end 22 can be, but is not limited to, detachably fixedly connected with the box body 21 through clamping or plugging. For another example, the second electrical connection end 22 can be, but is not limited to, fixedly connected with the box body 21 through gluing or injection molding.

[0074] ​When the charging device 20 is in electrical connection with the food temperature probe 10, the second electrical connection end 22 of the charging device 20 is in contact with the first electrical connection end 12 of the food temperature probe 10. At this time, if the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as a data transmission interface, data transmission between the charging device 20 and the food temperature probe 10 can be realized. At this time, if the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as a charging interface, the charging device 20 can charge the food temperature probe 10. When the charging device 20 is in electrical disconnection with the food temperature probe 10, the second electrical connection end 22 of the charging device 20 is spaced apart from (i.e., not in contact with) the first electrical connection end 12 of the food temperature probe 10. At this time, data transmission between the charging device 20 and the food temperature probe 10 cannot be realized, and the charging device 20 cannot charge the food temperature probe 10.

[0075] Please refer to Figure 3 , Figure 3 The flowchart of the information interaction method between the food temperature probe and the charging device in an embodiment of the present application is shown in FIG. 2. As shown in FIG. 2, the method comprises the following steps: Figure 3

[0076] Step S202: The charging device 20 acquires a detection signal generated by the food temperature probe 10 when the food temperature probe 10 is electrically connected to the charging device 20.

[0077] It can be understood that there is a box insertion detection process between the charging device 20 and the food temperature probe 10. When the food temperature probe 10 is inserted into the charging device 20, the charging device 20 and the food temperature probe 10 are in electrical connection, the second electrical connection end 22 of the charging device 20 is in contact with the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal. When the food temperature probe 10 is not inserted into the charging device 20, the charging device 20 and the food temperature probe 10 are in electrical disconnection, the second electrical connection end 22 of the charging device 20 is not in contact with the first electrical connection end 12 of the food temperature probe 10 and will not generate the above-mentioned detection signal. Therefore, the "detection signal" is understood as a box insertion signal for confirming that the food temperature probe 10 has been inserted into the charging device 20.

[0078] ​After the food temperature probe 10 is inserted into the charging device 20, the charging device 20 and the food temperature probe 10 are in an electrical connection state, the second electrical connection end 22 of the charging device 20 contacts the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal, the first master control chip of the charging device 20 acquires the detection signal, and the first master control chip of the charging device 20 generates an interaction signal according to the detection signal. At this time, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 serve as a data transmission interface, and the interaction signal is sent to the second master control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10.

[0079] Step S204: The food temperature probe 10 sends a feedback signal to the charging device 20 according to the interaction signal.

[0080] It can be understood that after the interaction signal is sent to the second master control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, the second master control chip of the food temperature probe 10 generates a feedback signal according to the interaction signal. At this time, the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 serve as a data transmission interface, and the feedback signal is sent to the first master control chip of the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20.

[0081] Step S206: The charging device 20 binds with the food temperature probe 10 based on the feedback signal.

[0082] It can be understood that after the feedback signal is sent to the first master control chip of the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20, the first master control chip of the charging device 20 confirms to bind with the current food temperature probe 10 based on the feedback signal.

[0083] Based on the information interaction method of the food temperature probe 10 and the charging device 20 in the embodiment of the present application, after the charging device 20 is loaded with the food temperature probe 10, the second electrical connection end 22 of the charging device 20 contacts the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal, and the charging device 20 generates an interaction signal according to the detection signal. At this time, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as a data transmission interface, and the interaction signal is sent to the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10. After the interaction signal is sent to the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, the food temperature probe 10 generates a feedback signal according to the interaction signal. At this time, the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 are used for data transmission, and the feedback signal is sent to the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20. After the feedback signal is sent to the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20, the charging device 20 confirms the binding with the current food temperature probe 10 based on the feedback signal. In this way, the binding between the charging device 20 and the food temperature probe 10 is realized by using the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 as a data transmission interface. Compared with the related art which uses a USB interface to realize data transmission, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 can realize electrical connection to transmit data directly through contact, and the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are not easy to loosen, which can effectively enhance the stability of the communication connection.

[0084] It is worth mentioning that for the food temperature probe 10 which has requirements on the overall size, transmitting data by designing the second electrical connection end 22 of the charging device 20 to contact the first electrical connection end 12 of the food temperature probe 10 is more conducive to realizing the miniaturization design of the food temperature probe 10 and reducing the manufacturing cost.

[0085] Further, the above-mentioned interaction signal includes a handshake signal and a connection signal. The "handshake signal" is understood as "the electrical signal sent by the charging device 20 to the food temperature probe 10 through the second electrical connection end 22, used to confirm that the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 have been reliably contacted, so as to establish a communication link".

[0086] Please refer to Figure 4 , Figure 4Fig. 2 is a flowchart of the information interaction method between the food temperature probe and the charging device in another embodiment of the present application. As shown in Fig. 2, the above step S202 includes the following steps: Figure 4

[0087] Step S301: The charging device 20 acquires the detection signal when the first electrical connection end 12 of the food temperature probe 10 electrically connects the second electrical connection end 22 of the charging device 20.

[0088] Step S302: The charging device 20 sends the handshake signal to the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 according to the detection signal.

[0089] It can be understood that when the food temperature probe 10 is loaded into the charging device 20, the charging device 20 and the food temperature probe 10 are in an electrical connection state, the second electrical connection end 22 of the charging device 20 contacts the first electrical connection end 12 of the food temperature probe 10 and generates the detection signal, the first master control chip of the charging device 20 acquires the detection signal, the first master control chip of the charging device 20 generates the handshake signal according to the detection signal, at this time, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as a data transmission interface, and the handshake signal is sent to the second master control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10.

[0090] Step S303: The food temperature probe 10 interrupts the handshake detection according to the handshake signal.

[0091] It can be understood that the "handshake detection" refers to a short-time, low-power electrical identification process before formal communication after the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are physically connected (i.e., in contact), which is used to confirm whether the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are in good contact and whether the charging device 20 and the food temperature probe 10 can start communication. After the handshake signal is sent to the second master control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, the second master control chip of the food temperature probe 10 can confirm that the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are in good contact and that the charging device 20 and the food temperature probe 10 can start communication according to the handshake signal, and interrupts the handshake detection.

[0092] ​Step S304: The charging device 20 sends a connection signal to the food temperature probe 10 according to the detection signal through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10.

[0093] It can be understood that when the food temperature probe 10 is loaded into the charging device 20, the charging device 20 and the food temperature probe 10 are in an electrical connection state, the second electrical connection end 22 of the charging device 20 is in contact with the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal, the first main control chip of the charging device 20 acquires the detection signal, and the first main control chip of the charging device 20 generates a connection signal according to the detection signal. At this time, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 serve as a data transmission interface, and the connection signal is sent to the second main control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10.

[0094] The above step S204 specifically includes: the food temperature probe 10 sends a feedback signal to the charging device 20 according to the connection signal through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20.

[0095] It can be understood that after the connection signal is sent to the second main control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, the second main control chip of the food temperature probe 10 generates a feedback signal according to the connection signal. At this time, the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 serve as a data transmission interface, and the feedback signal is sent to the first main control chip of the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20.

[0096] In the present application, after the food temperature probe 10 is loaded into the charging device 20, the second electrical connection end 22 of the charging device 20 is in contact with the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal, the charging device 20 generates a handshake signal according to the detection signal to confirm that the second electrical connection end 22 of the charging device 20 is in good contact with the first electrical connection end 12 of the food temperature probe 10 and establishes a communication link, and the charging device 20 also generates a connection signal according to the detection signal. The second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 serve as a data transmission interface for realizing effective transmission of the handshake signal and the connection signal between the charging device 20 and the food temperature probe 10.

[0097] Specifically, please refer to Figure 5 , Figure 5This is a timing diagram illustrating the information interaction method between a food temperature probe and a charging device in one embodiment of this application. Figure 5 As shown, after executing step S302, the charging device 20 delays for a first preset time before executing step S304. That is, after the charging device 20 sends a handshake signal to the food temperature probe 10 based on the detection signal and through its second electrical connection terminal 22 and the first electrical connection terminal 12, a timer (which can be independent of the first main control chip of the charging device 20 or directly integrated into it) starts timing. The timer continues until the timing reaches the first preset time, at which point the charging device 20 sends an activation signal to the food temperature probe 10 based on the detection signal and through its second electrical connection terminal 22 and the first electrical connection terminal 12. The first preset time is greater than or equal to 30 milliseconds and less than or equal to 100 milliseconds; for example, the specific value of the first preset time can be, but is not limited to, 30 milliseconds, 40 milliseconds, 50 milliseconds, 60 milliseconds, 70 milliseconds, 80 milliseconds, 90 milliseconds, or 100 milliseconds. In this embodiment, the first preset time is 60 milliseconds. This design ensures that the handshake signal is effectively sent from the charging device 20 to the food temperature probe 10, establishing a communication link between the food temperature probe 10 and the charging device 20, and causing the food temperature probe 10 to interrupt the handshake detection based on the handshake signal.

[0098] Further, please refer to Figure 6 , Figure 6 This is a flowchart illustrating the information interaction method between a food temperature probe and a charging device in another embodiment of this application. Figure 6 As shown, the method also includes step S201, which is performed before step S202 described above.

[0099] Step S201: The charging device 20 enables charging, enables handshake detection, and disables serial port transmission; the food temperature probe 10 enables charging, enables handshake detection, disables serial port transmission, and disables serial port reception.

[0100] It is understandable that, for the charging device 20, "charging enable" refers to a logic signal issued by the first main control chip of the charging device 20, which enables or disables the charging device 20 from outputting charging voltage / current to the food temperature probe 10 (that is, determines whether the charging device 20 "starts to supply power"). Only when the signal is valid will the charging circuit of the charging device 20 be turned on and start supplying power to the food temperature probe 10. If the signal is invalid, the charging circuit of the charging device 20 will be cut off, and charging will not occur even if the second electrical connection terminal 22 of the charging device 20 and the first electrical connection terminal 12 of the food temperature probe 10 are in good physical contact.

[0101] For the food temperature probe 10, the "charge enable" refers to a logic signal sent by the second master chip of the food temperature probe 10, which functions to allow or prohibit the food temperature probe 10 from receiving the charging voltage / current output by the charging device 20 (i.e., determines whether the food temperature probe 10 "starts charging"); only when the signal is in an active state, the charging circuit of the food temperature probe 10 is turned on to start receiving the charging voltage / current output by the charging device 20; if the signal is invalid, the charging circuit of the food temperature probe 10 is cut off, and the food temperature probe 10 will not charge even if the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 are in good physical contact.

[0102] In step S201, the TX interface of the first master chip of the charging device 20 is placed in a high-impedance state or a logic idle state; the TX interface of the second master chip of the food temperature probe 10 is placed in a high-impedance state or a logic idle state, and the RX interface of the second master chip of the food temperature probe 10 is placed in a high-impedance state or a logic idle state; at this time, only the power supply and handshake detection lines are reserved between the charging device 20 and the food temperature probe 10, and the communication channel is actively closed.

[0103] Further, please continue to refer to Figure 6 The method further includes steps S305 and S306 performed after step S303 and before step S304.

[0104] Step S305: the food temperature probe 10 closes the charge enable, closes the handshake detection, closes the serial port sending, and opens the serial port receiving.

[0105] In step S305, the TX interface of the second master chip of the food temperature probe 10 is placed in a high-impedance state or a logic idle state, and the RX interface of the second master chip of the food temperature probe 10 is switched from a high-impedance state or a logic idle state to an active driving mode; at this time, only the communication channel is reserved between the food temperature probe 10 and the charging device 20, and the power supply and handshake detection lines are actively closed.

[0106] Step S306: the charging device 20 closes the charge enable, closes the handshake detection, opens the serial port sending, and closes the serial port receiving.

[0107] In step S306, the TX interface of the first master chip of the charging device 20 is switched from a high-impedance state or a logic idle state to an active driving mode, and the RX interface of the first master chip of the charging device 20 is placed in a high-impedance state or a logic idle state; at this time, only the communication channel is reserved between the charging device 20 and the food temperature probe 10, and the power supply and handshake detection lines are actively closed.

[0108] Further, please continue to refer toFigure 6 The method further comprises steps S307 and S308 performed after step S304 and before step S204.

[0109] Step S307: The charging device 20 closes the charging enable, closes the handshake detection, closes the serial port sending, and opens the serial port receiving.

[0110] In step S307, the TX interface of the first master control chip of the charging device 20 is placed in a high-impedance state or a logic idle state, and the RX interface of the first master control chip of the charging device 20 is switched from a high-impedance state or a logic idle state to an active driving mode; at this time, only a communication channel is reserved between the charging device 20 and the food temperature probe 10, and the power supply and handshake detection lines are actively closed.

[0111] Step S308: The food temperature probe 10 closes the charging enable, closes the handshake detection, opens the serial port sending, and closes the serial port receiving.

[0112] In step S308, the TX interface of the second master control chip of the food temperature probe 10 is switched from a high-impedance state or a logic idle state to an active driving mode, and the RX interface of the second master control chip of the food temperature probe 10 is placed in a high-impedance state or a logic idle state; at this time, only a communication channel is reserved between the food temperature probe 10 and the charging device 20, and the power supply and handshake detection lines are actively closed.

[0113] Further, please continue to refer to Figure 6 The method further comprises step S208, which specifically comprises: after the charging device 20 and the food temperature probe 10 complete binding, the food temperature probe 10 opens the charging enable, opens the handshake detection, closes the serial port sending, and closes the serial port receiving, and the charging device 20 opens the charging enable, closes the handshake detection, closes the serial port sending, and closes the serial port receiving, and then the charging device 20 charges the food temperature probe 10 through the second electrical connection end 22 and the first electrical connection end 12.

[0114] It can be understood that after the charging device 20 and the food temperature probe 10 complete binding, at this time the communication between the charging device 20 and the food temperature probe 10 is completed, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as charging interfaces, and the charging signal output by the first battery of the charging device 20 is transmitted to the second battery of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, so that the charging device 20 can charge the food temperature probe 10.

[0115] It should be noted that the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 not only serve as a data transmission interface for realizing data transmission between the charging device 20 and the food temperature probe 10, but also serve as a charging interface for realizing charging connection between the charging device 20 and the food temperature probe 10. In the present application, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are multiplexed to realize one-way communication, that is, when the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 serve as a data transmission interface to transmit data, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 cannot be used as a charging interface to realize charging connection, and vice versa, when the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 serve as a charging interface to realize charging connection, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 cannot be used as a data transmission interface to transmit data.

[0116] Specifically, as shown in Figure 5 After the charging device 20 executes the above step S306, the charging device 20 delays for a second preset time and then executes the above step S307. That is, after the charging device 20 closes the charging enable, closes the handshake detection, opens the serial port sending, and closes the serial port receiving, a timer (which can be independent of the first master control chip of the charging device 20, or can be directly integrated in the first master control chip of the charging device 20) starts timing, and the charging device 20 will not close the charging enable, close the handshake detection, close the serial port sending, and open the serial port receiving until the timing time of the timer reaches the second preset time. The second preset time is greater than or equal to 10 milliseconds and less than or equal to 50 milliseconds; for example, the specific value of the second preset time can be but is not limited to 10 milliseconds, 20 milliseconds, 30 milliseconds, 40 milliseconds, or 50 milliseconds, etc. In the embodiment of the present application, the second preset time is 10 milliseconds. In this way, it can be ensured that the handshake signal is effectively transmitted from the side where the charging device 20 is located to the side where the food temperature probe 10 is located (that is, waiting for the completion of the transmission of the handshake signal).

[0117] Please refer to Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the binding of the food temperature probe and the second charging device in an embodiment of the present application; Figure 8 is a flowchart of the information interaction method between the food temperature probe and the charging device in another embodiment of the present application. As Figure 8As shown in the above step S206, it is confirmed whether the food temperature probe 10 is a new needle that is not bound. When the food temperature probe 10 is a new needle that is not bound, a binding confirmation signal is sent to the mobile terminal. In response to receiving the user returning the confirmation binding signal through the mobile terminal, the new needle that is not bound is wirelessly bound.

[0118] It can be understood that the above communication signal includes an instruction for requesting to query the host information and the code information of the food temperature probe 10. The above feedback signal includes the host information and the code information of the food temperature probe 10. The host information can be the MAC address of the food temperature probe 10, and the code information can be the letter information or the number information currently assigned to the food temperature probe 10.

[0119] Each charging device 20 is configured with multiple (at least two) food temperature probes 10 that have different host information, and each charging device 20 assigns corresponding code information to the multiple food temperature probes 10 that have different host information and are configured therewith according to the binding order of the food temperature probes 10. For any charging device 20, the “new needle that is not bound” is the food temperature probe 10 that has not been bound to the charging device 20, and the charging device 20 determines whether the current food temperature probe 10 is a new needle that is not bound through the host information. When the charging device 20 determines that the current food temperature probe 10 is a new needle that is not bound according to the host information, the charging device 20 sends a binding confirmation signal to the mobile terminal. The user can select whether to send a confirmation binding signal to the charging device 20 through the mobile terminal according to actual needs, and the user sends the confirmation binding signal to the charging device 20 through the mobile terminal. The charging device 20 wirelessly binds the new needle that is not bound based on the confirmation binding signal.

[0120] Specifically, please refer to Figure 9 , Figure 9 The flowchart of the information interaction method between the food temperature probe and the charging device in another embodiment of the present application is shown in FIG. 4. Figure 12 As shown in the above step S206, in response to receiving the user returning the confirmation binding signal through the mobile terminal, the step of wirelessly binding the new needle that is not bound includes:

[0121] Step S402: The charging device 20 sends a binding signal and new code information to the new needle that is not bound through the second electrical connection end 22 and the first electrical connection end 12.

[0122] It can be understood that when the user selects to send the confirmation binding signal to the charging device 20 through the mobile terminal, the charging device 20 sends the binding signal and the new code information to the new needle that is not bound through the second electrical connection end 22 and the first electrical connection end 12.

[0123] Step S404: The unbound new probe initiates broadcasting and feeds back the new encoding information to the charging device 20 according to the binding signal and the new encoding information.

[0124] Step S406: The charging device 20 scans the obtained broadcasting and detects the new encoding information, and then completes wireless connection with the unbound new probe.

[0125] Specifically, the wireless connection is a 2.4G Bluetooth connection. The short-distance wireless communication between the charging device 20 and the food temperature probe 10 is realized through a Bluetooth wireless link in the 2.4GHz ISM frequency band, which can reduce the manufacturing cost and power consumption of the charging device 20 and the food temperature probe 10, and can also reduce the overall volume of the food temperature probe 10.

[0126] Please refer to Figure 10 - Figure 12 , Figure 10 for the frame diagram of the binding of the first charging device and the configured food temperature probe in an embodiment of the present application, and the binding of the second charging device and the food temperature probe configured therewith; Figure 11 for the frame diagram of the binding of the first food temperature probe as an unbound new probe and the second charging device in an embodiment of the present application; Figure 12 for the frame diagram of the binding of the fifth food temperature probe as an unbound new probe and the first charging device in an embodiment of the present application.

[0127] Hereinafter, the binding principle between the charging device 20 and the food temperature probe 10 will be introduced in detail taking the number of charging devices 20 as two and each of the two charging devices 20 being configured with four food temperature probes 10 as an example.

[0128] As shown in Figure 10 , the two charging devices 20 are a first charging device 201 and a second charging device 202; the first charging device 201 is configured with a first food temperature probe 101, a second food temperature probe 102, a third food temperature probe 103, and a fourth food temperature probe 104; and the second charging device 202 is configured with a fifth food temperature probe 105, a sixth food temperature probe 106, a seventh food temperature probe 107, and an eighth food temperature probe 108.

[0129] For the first charging device 201: in the binding order of the first food temperature probe 101→ the second food temperature probe 102→ the third food temperature probe 103→ the fourth food temperature probe 104, the first charging device 201 is sequentially bound with the first food temperature probe 101; when the first charging device 201 is bound with the first food temperature probe 101, the first charging device 201 counts once (num=0+1=1), at this time, the first charging device 201 assigns the code information of the first food temperature probe 101 as 1; when the first charging device 201 is bound with the second food temperature probe 102, the first charging device 201 counts again (num=1+1=2), at this time, the first charging device 201 assigns the code information of the second food temperature probe 102 as 2; when the first charging device 201 is bound with the third food temperature probe 103, the first charging device 201 counts again (num=2+1=3), at this time, the first charging device 201 assigns the code information of the third food temperature probe 103 as 3; when the first charging device 201 is bound with the fourth food temperature probe 104, the first charging device 201 counts again (num=3+1=4), at this time, the first charging device 201 assigns the code information of the fourth food temperature probe 104 as 4.

[0130] For the second charging device 202: in the binding order of the eighth food temperature probe 108→ the seventh food temperature probe 107→ the sixth food temperature probe 106→ the fifth food temperature probe 105, the second charging device 202 is sequentially bound with the eighth food temperature probe 108; when the second charging device 202 is bound with the eighth food temperature probe 108, the second charging device 202 counts once (num=0+1=1), at this time, the second charging device 202 assigns the code information of the eighth food temperature probe 108 as 1; when the second charging device 202 is bound with the seventh food temperature probe 107, the second charging device 202 counts again (num=1+1=2), at this time, the second charging device 202 assigns the code information of the seventh food temperature probe 107 as 2; when the second charging device 202 is bound with the sixth food temperature probe 106, the second charging device 202 counts again (num=2+1=3), at this time, the second charging device 202 assigns the code information of the sixth food temperature probe 106 as 3; when the second charging device 202 is bound with the fifth food temperature probe 105, the second charging device 202 counts again (num=3+1=4), at this time, the second charging device 202 assigns the code information of the fifth food temperature probe 105 as 4.

[0131] As Figure 11As shown, for the first charging device 201, the fifth food temperature probe 105, the sixth food temperature probe 106, the seventh food temperature probe 107 and the eighth food temperature probe 108 are all "new needles not bound"; if the fifth food temperature probe 105 needs to be bound with the first charging device 201, the first charging device 201 counts once (num = 4 + 1 = 5) at this time, the first charging device 201 gives the new code information of the fifth food temperature probe 105 as 5, and the first charging device 201 sends the binding signal and the new code information to the fifth food temperature probe 105 through the second electric connection end 22 and the first electric connection end 12 (at this time, the code information of the fifth food temperature probe 105 is from 4→5); since the new code is inconsistent with the original binding code of the probe stored in the second charging device 202, the fifth food temperature probe 105 is immediately disconnected with the second charging device 202, the fifth food temperature probe 105 initiates the broadcast and feedback of the new code information to the first charging device 201 according to the binding signal and the new code information, the first charging device 201 scans the broadcast obtained and detects the new code information, and then completes the wireless connection with the fifth food temperature probe 105. At this time, the first charging device 201 is bound with the first food temperature probe 101, the second food temperature probe 102, the third food temperature probe 103, the fourth food temperature probe 104 and the fifth food temperature probe 105. It should be noted that the number of food temperature probes 10 that can be bound by the first charging device 201 is not limited, and the user can wirelessly bind the first charging device 201 with the corresponding food temperature probe 10 according to the actual needs, and the first charging device 201 gives the new code information to the corresponding new needle not bound by the cumulative counting method.

[0132] As Figure 12As shown, for the second charging device 202, the first food temperature probe 101, the second food temperature probe 102, the third food temperature probe 103 and the fourth food temperature probe 104 are all "new needles not bound"; if the first food temperature probe 101 needs to be bound with the second charging device 202, the second charging device 202 counts once (num = 4 + 1 = 5) at this time, the second charging device 202 gives the first food temperature probe 101 a new code information 5, and the second charging device 202 sends a binding signal and a new code information to the first food temperature probe 101 through the second electrical connection end 22 and the first electrical connection end 12 (at this time, the code information of the first food temperature probe 101 is from 1→5), the first food temperature probe 101 initiates a broadcast and feeds back a new code information to the second charging device 202 according to the binding signal and the new code information, and the second charging device 202 scans the broadcast obtained and detects the new code information to complete wireless connection with the first food temperature probe 101. At this time, the second charging device 202 is bound with the first food temperature probe 101, the fifth food temperature probe 105, the sixth food temperature probe 106, the seventh food temperature probe 107 and the eighth food temperature probe 108. It should be noted that the number of food temperature probes 10 that can be bound by the second charging device 202 is not limited, and the user can wirelessly bind the second charging device 202 with the corresponding food temperature probe 10 according to actual needs, and the second charging device 202 gives the corresponding new needle a new code information by means of cumulative counting.

[0133] Please refer to Figure 13 , Figure 13 The flowchart of the information interaction method of the charging device in an embodiment of the present application is shown in FIG. 5. As shown in FIG. 5, the method comprises the following steps: Figure 13

[0134] Step S502: The second electrical connection end 22 of the charging device 20 is electrically connected to the first electrical connection end 12 of the food temperature probe 10 to generate a detection signal, and an interaction signal is sent to the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 according to the detection signal.

[0135] ​It can be understood that when the food temperature probe 10 is loaded into the charging device 20, the charging device 20 and the food temperature probe 10 are in an electrical connection state, the second electrical connection end 22 of the charging device 20 is in contact with the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal, the first master control chip of the charging device 20 acquires the detection signal, and the first master control chip of the charging device 20 generates an interaction signal according to the detection signal. At this time, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as a data transmission interface, and the interaction signal is sent to the first electrical connection end 12 of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20, and then sent to the second master control chip of the food temperature probe 10 through the first electrical connection end 12 of the food temperature probe 10.

[0136] Step S504: receiving the feedback signal of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and binding with the food temperature probe 10 based on the feedback signal.

[0137] It can be understood that after the interaction signal is sent to the second master control chip of the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, the second master control chip of the food temperature probe 10 generates a feedback signal according to the interaction signal. At this time, the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 are used as a data transmission interface, the feedback signal is sent to the second electrical connection end 22 of the charging device 20 through the first electrical connection end 12 of the food temperature probe 10, and then sent to the first master control chip of the charging device 20 through the second electrical connection end 22 of the charging device 20. The first master control chip of the charging device 20 confirms the binding with the current food temperature probe 10 based on the feedback signal.

[0138] Based on the information interaction method of the charging device 20 in the embodiment of the present application, after the food temperature probe 10 is loaded into the charging device 20, the second electrical connection end 22 of the charging device 20 contacts the first electrical connection end 12 of the food temperature probe 10 and generates a detection signal, and the charging device 20 generates an interaction signal according to the detection signal. At this time, the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 are used as a data transmission interface, and the interaction signal is sent to the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10. After the interaction signal is sent to the food temperature probe 10 through the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10, the food temperature probe 10 generates a feedback signal according to the interaction signal. At this time, the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20 are used for data transmission, and the feedback signal is sent to the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20. After the feedback signal is sent to the charging device 20 through the first electrical connection end 12 of the food temperature probe 10 and the second electrical connection end 22 of the charging device 20, the charging device 20 confirms the binding with the current food temperature probe 10 based on the feedback signal. In this way, the binding between the charging device 20 and the food temperature probe 10 is realized by using the second electrical connection end 22 of the charging device 20 and the first electrical connection end 12 of the food temperature probe 10 as a data transmission interface.
