Description

Technical Field

[0001] The invention relates to the technical field of electric baking pans, and in particular to an oil-sprayable electric baking pan. Background Art

[0002] Cooking oil, also known as "edible oil", refers to animal or plant oils used in the process of making food. It is liquid at room temperature. Due to the source of raw materials, processing technology and quality, most common cooking oils are plant oils, including corn oil, rapeseed oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, palm oil, canola oil, sunflower oil, soybean oil, sesame oil, flaxseed oil (sesame oil), grape seed oil, walnut oil, peony seed oil, etc.

[0003] It can be seen that cooking oil is one of the important materials for people to make food. The electric baking pan is a new cooking tool. It is simple to operate and easy to use, and can heat both the upper and lower sides at the same time. When people use the electric baking pan to make food, according to the needs of the food production process, sometimes they need to apply cooking oil on the bottom and top of the food. The cooking oil applied to the bottom of the food will exist for a long time due to the effect of gravity, while the cooking oil applied to the top of the food will instantly flow to the bottom of the food due to the effect of gravity. Therefore, the operator needs to constantly open the electric baking pan and apply cooking oil on the top of the food frequently. Such operation is not only time-consuming and laborious, but also frequently opening the electric baking pan to allow steam to flow out, which seriously affects the quality of food production.

[0032] A liquid level meter is arranged in the kettle body, and the liquid level meter is connected to the controller, and the controller is connected to the host computer, so that the liquid level data collected by the liquid level meter can be first transmitted to the controller, and then the controller sends the liquid level data to the host computer. The controller can be a single-chip microcomputer or a PLC, and the host computer can be a PC or a laptop computer. The controller is connected to a wireless communication module 1, and the host computer is connected to a wireless communication module 2. The wireless communication module 1 is connected to the wireless communication module 2 via a wireless network. The wireless communication module 1 can be a WIFI module or a 3G module, and the wireless communication module 2 can be a WIFI module or a 3G module, and the wireless network can be a WLAN or a 3G network;

[0033] If the host computer frequently runs the startup module to send liquid level data to the controller via the wireless network, the controller will also frequently transmit feedback message 1 and feedback message 2 to the host computer via the wireless network, that is, the controller and the host computer perform data interaction, and the interaction method includes the following process:

[0034] A-1: Get the data to be transmitted;

[0035] Here, if the process is applied on a host computer, the host computer regards the liquid level data as data to be transmitted;

[0036] If the process is applied to a controller, the data to be transmitted includes feedback message 1 and feedback message 2, and the feedback message 1 and feedback message 2 are regarded as the data to be transmitted;

[0037] A-2: Based on the data to be transmitted, a corresponding data frame is constructed, where the frame header of the data frame includes 8*t bits, and k is greater than 8*t, where k is the number of bits in the frame header in the 802.11 standard, the 3G standard or the 4G standard.

[0038] At present, when the host computer and the controller execute data frame transmission, they follow the 802.11 standard, 3G standard or 4G standard. When the data transmission between the host computer and the controller is executed via the 802.11 standard, 3G standard or 4G standard, the frame header of the transmitted data frame often contains redundant idle data, so that the frame header contains a large number of bits, which will occupy a lot of data in the data link.

[0039] However, in the improved process, the host computer or controller sets a unique standard in advance. After obtaining the data to be transmitted, the host computer or controller constructs the corresponding data frame based on the unique standard. The frame header in the data frame is 8*t bits, and the 8*t bits often contain the number of bits of the data frame; the number of bits of the data frame is often 24 bits. If the frame header only contains the number of bits of the data frame, then the value of 8*t is 24. In addition, the frame header can also carry other data, but it must meet the condition that k is greater than 8*t.

[0040] The beneficial effects of the present invention are:

[0041] When using the oil-spraying electric baking pan of the present invention, there is no need to repeatedly open the electric baking pan as in the case of using an ordinary electric baking pan. When oil spraying is required, the user can press down the pressing block to raise the upper hot pan, and then press the oil spray button. Press the button lightly to spray a small amount of oil from a single hole, and press the button hard to spray oil from multiple holes at the same time. After the oil spraying is completed, the user pulls the pull rod to lower the upper hot pan under the action of gravity to continue making. According to the needs of the food production process, when oil spraying is required, the upper hot pan can be sprayed directly without raising it. The two production methods allow users to choose at any time according to their needs, and are highly flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The host computer runs the startup module to send the liquid level data to the controller via the wireless network. In addition, the controller will also transmit feedback message 1 and feedback message 2 to the host computer via the wireless network. Here, when data is transmitted between the host computer and the controller, the standard relied on is often the 802.11 standard, 3G standard or 4G standard. When data transmission is performed via the 802.11 standard, 3G standard or 4G standard, the data transmitted between the host computer and the controller is in a data frame format. The data frame includes a frame header and a data part. Here, the frame header generally contains 8*t bits, and the data part contains the secondary transmitted data.

[0061] However, in practice, if the host computer frequently runs the startup module to send liquid level data to the controller via the wireless network, and the controller frequently transmits feedback message 1 and feedback message 2 to the host computer via the wireless network, that is, when the controller and the host computer interact with each other, the data frame length will be large, which will occupy a lot of data in the data link between the controller and the host computer.

[0062] After improvement, the structure of connecting the controller with the host computer generally adopts the following method:

[0063] A liquid level meter is arranged in the kettle body, and the liquid level meter is connected to the controller, and the controller is connected to the host computer, so that the liquid level data collected by the liquid level meter can be first transmitted to the controller, and then the controller sends the liquid level data to the host computer. The controller can be a single-chip microcomputer or a PLC, and the host computer can be a PC or a laptop computer. The controller is connected to a wireless communication module 1, and the host computer is connected to a wireless communication module 2. The wireless communication module 1 is connected to the wireless communication module 2 via a wireless network. The wireless communication module 1 can be a WIFI module or a 3G module, and the wireless communication module 2 can be a WIFI module or a 3G module, and the wireless network can be a WLAN or a 3G network;

[0064] If the host computer frequently runs the startup module to send liquid level data to the controller via the wireless network, the controller will also frequently transmit feedback message 1 and feedback message 2 to the host computer via the wireless network, that is, the controller and the host computer perform data interaction, and the interaction method includes the following process:

[0065] A-1: Get the data to be transmitted;

[0066] Here, if the process is applied on a host computer, the host computer regards the liquid level data as data to be transmitted;

[0067] If the process is applied to a controller, the data to be transmitted includes feedback message 1 and feedback message 2, and the feedback message 1 and feedback message 2 are regarded as the data to be transmitted;

[0068] A-2: Based on the data to be transmitted, a corresponding data frame is constructed, where the frame header of the data frame includes 8*t bits, and k is greater than 8*t, where k is the number of bits in the frame header in the 802.11 standard, the 3G standard or the 4G standard.

[0069] At present, when the host computer and the controller execute data frame transmission, they follow the 802.11 standard, 3G standard or 4G standard. When the data transmission between the host computer and the controller is executed via the 802.11 standard, 3G standard or 4G standard, the frame header of the transmitted data frame often contains redundant idle data, so that the frame header contains a large number of bits, which will occupy a lot of data in the data link.

[0070] However, in the improved process, the host computer or controller sets a unique standard in advance. After obtaining the data to be transmitted, the host computer or controller constructs the corresponding data frame based on the unique standard. The frame header in the data frame is 8*t bits, and the 8*t bits often contain the number of bits of the data frame; the number of bits of the data frame is often 24 bits. If the frame header only contains the number of bits of the data frame, then the value of 8*t is 24. In addition, the frame header can also carry other data, but it must meet the condition that k is greater than 8*t.

[0071] Also, in the data frame, the data portion has data to be transmitted;

[0072] A-3: transmitting the data frame;

[0073] If the process is applied to a host computer, the host computer transmits the corresponding data frame to a controller after constructing the data frame; if the process is applied to a controller, the controller transmits the corresponding data frame to the host computer after constructing the data frame.

[0074] A-1 to A-3 are data transmission processes used in the interactive system composed of the controller and the host computer. This process is used in the host computer or controller in the interactive system composed of the controller and the host computer. In this process, the data to be transmitted is first obtained, and the corresponding data frame is constructed based on the data to be transmitted. Here, the frame header of the data frame includes 8*t bits, and k is greater than 8*t, k is the number of bits in the frame header in the 802.11 standard, 3G standard or 4G standard, and then the data frame is transmitted. Through this process, the number of bits of the data frame to be transmitted is reduced, which can save the amount of data in the data link between the controller and the host computer. In particular, when the number of data transmissions between the host computer and the controller is not small, it can often be hundreds or thousands of times, and the data transmitted is not small, so through this process, a lot of data in the data link between the controller and the host computer can be saved.

[0075] In addition, the method of transmitting the data frame in A-3 includes:

[0076] A-3-1: After constructing the data frame, temporarily storing the data frame;

[0077] A-3-2: Determine whether the temporarily stored data frame meets the preset transfer limit value, where the transfer limit value includes: a duration limit value or a bit number limit value. If yes, execute A-3-3; if not, execute A-3-4;

[0078] A-3-3: If the determination value indicates that the temporarily stored data frame meets the preset transfer threshold value, then transfer each temporarily stored data frame;

[0079] A-3-4: If the determination value indicates that the temporarily stored data frame does not meet the pre-set transfer threshold, continue to temporarily store the data frame;

[0080] From A-3-1 to A-3-4, after constructing the corresponding data frame based on the data to be transmitted, the data frame is temporarily stored, and it is determined whether the temporarily stored data frame meets the pre-set transmission limit value. When the temporarily stored data frame meets the pre-set transmission limit value, each temporarily stored data frame is transmitted.

[0081] In this way, the data frame can be transmitted only when the constructed data frame meets the pre-set transmission limit value, thereby reducing the number of times the host computer or controller transmits data frames, and saving a lot of data in the data link between the controller and the host computer.

[0082] Here, the pre-set transmission limit value includes two types: a duration limit value or a bit quantity limit value. Using different transmission limit values, the method of determining whether the temporarily stored data frame meets the pre-set transmission limit value is also different.

[0083] If the transfer limit value is a duration limit value, determining whether the temporarily stored data frame meets the preset transfer limit value includes:

[0084] If no data frame has been transmitted before, determine whether the time period between the current and first data frame formation times is higher than the duration limit value. If so, determine that the temporarily stored data frame meets the pre-set limit value. If not, determine that the temporarily stored data frame does not meet the pre-set limit value, and continue to temporarily store the data frame.

[0085] Here, the first data frame refers to the first temporarily stored data frame.

[0086] In addition, if a data frame has been transmitted before, determine whether the time period between the composition time of the data frame and the time of the previous data frame transmission is higher than the duration limit value. If so, determine that the temporarily stored data frame meets the pre-set limit value. If not, determine that the temporarily stored data frame does not meet the pre-set limit value and continue to temporarily store the data frame.

[0087] Here, the duration limit value can be set according to the specific data transmission requirements, for example, the duration limit value can be set to 1500ms. Naturally, the duration limit value can also be set to another amount without any constraints.

[0088] Here, it is determined whether the temporarily stored data frame meets the pre-set transfer limit value through the current construction time of the data frame, or the time period between the construction time of the data frame and the last transmitted data frame; in this way, when executing data transmission, the constructed data frame cannot be transmitted in time, but the data frame is temporarily stored until there is a constructed data frame that meets the time limit value, and each temporarily stored data frame can be transmitted; through the said method, the number of data frame transmissions can be reduced, and the amount of data in the data link between the controller and the host computer can be saved; in particular, at present, the time length for executing data transmission between the host computer and the controller is generally several hundred ms, and the number of times is not small. Under this method, the time limit value is set according to the specific transmission requirements, just like the time limit value can be set to 1500ms, thereby reducing the number of data transmissions and saving the amount of data in the data link between the controller and the host computer.

[0089] Furthermore, if the pre-set transfer limit value is a bit quantity limit value, then the step of determining whether the temporarily stored data frame meets the pre-set limit value includes:

[0090] Determine whether the sum of the capacities of the temporarily stored data frames is greater than the bit quantity limit value. If so, determine that the temporarily stored data frames meet the pre-set transmission limit value. If not, continue to temporarily store the data frames.

[0091] In this way, after constructing the data frame, the data frame will be temporarily stored until the total size of the bits of each temporarily stored data frame is higher than the preset bit quantity limit value. Then, it is determined that the temporarily stored data frame meets the preset transmission limit value, and then each temporarily stored data frame is transmitted. This can reduce the number of data frame transmissions and save the amount of data in the data link between the controller and the host computer.

[0092] Here, in the data frame corresponding to the data to be transmitted, the number of bits in the frame header is not large, so that the number of bits in the entire data frame is not high. In this way, after the data frame is constructed, the data frame can be temporarily stored until the temporarily stored data frame meets the transmission limit value, and then each temporarily stored data frame is transmitted together. Because the number of bits in each data frame is reduced, it is difficult to cause congestion during the transmission.

[0093] In addition, during the execution, the execution performance of the controller will also change. In order to obtain the changing performance of the controller in real time, the data transmission method used in the interactive system composed of the controller and the host machine also includes:

[0094] Decoding the data to obtain the current variable performance of the controller;

[0095] By virtue of the variable performance, the previously set transfer limit value is changed.

[0096] The host computer arranged in the interactive system composed of the controller and the host computer can obtain the data transmitted by the controller, and the data includes the CPU usage rate and memory occupancy of the controller which can reflect the performance of the controller. In addition, the host computer can transmit the data of the controller performance to the controller. The host computer or the controller can decode the data, obtain the current performance of the controller through such data, and change the pre-set transfer limit value based on the performance data.

[0097] For example, when it is determined that the current performance of the controller is acceptable based on the decoded value, the transmission limit value can be improved to reduce the number of data transmissions; when it is determined that the current performance of the controller is poor based on the decoded value, the transmission limit value can be reduced to increase the number of data transmissions to obtain performance data in a timely manner.

[0098] The data transmission method applied to the interactive system composed of the controller and the host machine also includes:

[0099] B-1: after listening to the wireless communication module 1 or the wireless communication module 2 receiving the termination message, obtaining the data transmitted by the wireless communication module 2 or the wireless communication module 1;

[0100] The host computer and the controller are connected via wireless communication module 1 and wireless communication module 2. If the host computer detects that the wireless communication module 1 connected to it receives a stop message, it means that the controller has transmitted data to the host computer; if the controller detects that the wireless communication module 2 connected to it receives a stop message, it means that the host computer has transmitted data to the controller.

[0101] B-2: Determine whether the number of received bits is not higher than 8*t. If yes, execute B-3. If not, return to B-1 to continue receiving data after the last wireless serial port reception termination message is intercepted. t is a natural number, k is a natural number.

[0102] B-3: If it is determined by the determination value that the number of received bits is not less than 8*t, the received bit stream is decoded to obtain the number of bits of the data frame in the bit stream;

[0103] If the number of received bits is not less than 8*t, it means that all frame headers are received; because in this method, the frame header of the constructed data frame contains the number of bits of the data frame, the number of bits of the data frame can be obtained by decoding the frame header.

[0104] B-4: Determine whether all data frames transmitted by wireless communication module 1 or wireless communication module 2 are received based on the number of bits of the data frame. If yes, execute B-5. If not, return to B-1 and wait for the next wireless communication module 1 or wireless communication module 2 to receive a stop message. After the wireless communication module 1 or wireless communication module 2 receives the stop message, continue to receive data.

[0105] B-5: If all the data frames transmitted by the serial port are determined to be received based on the judgment value, the data type contained in the data part is obtained, and the data frame is stored accordingly based on the data type.

[0106] The data portion contains data to be transmitted and also contains the data type of the data to be transmitted. The data type is often in the format of a data identifier. Depending on the data type contained in the data portion, corresponding storage is performed on the data.

Those skilled in the art should understand that the present disclosure is not limited to the embodiments described above, and that various changes, modifications and substitutions may be made without departing from the scope of the present invention.
