On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] The cloud terminal is a brand-new terminal form born with the development of technology and the progress of terminal technology. After the cloud terminal is connected to the cloud server through a protocol, during use, the cloud terminal itself does not perform computing and storage, but places computing-intensive tasks such as computing, storage, and control on the cloud server for processing. That is, the system and data displayed by the cloud terminal are determined by the cloud server, and the cloud terminal only plays a role of connection and display, so as to achieve the same use effect as the physical terminal, and at the same time realize the development trend of the physical form being thin and light and transparent, meeting various needs of users.

[0036] The cloud terminal is provided with a variety of hardware modules, for example, power supply, audio, image, display, image, sensor, etc. During use, multiple hardware modules generate data correspondingly. After the cloud terminal obtains the data generated by the hardware, it sends the data to the cloud server for processing by the cloud server.

[0037] Therefore, the present disclosure provides a data transmission method to achieve reasonable and effective transmission of data when the cloud terminal transmits data to the cloud server.

[0038] Figure 1 is a schematic diagram of the architecture of a cloud terminal and a cloud server shown according to an exemplary embodiment of the present disclosure. Referring to Figure 1 , the cloud terminal establishes communication with the cloud server through a network communication or a mobile communication network for data transmission, and the cloud server performs data processing, data storage, etc. The cloud terminal is provided with a variety of sensors for sensing physical quantities such as light, magnetism, force, heat, capacitance, etc. As the physical quantities sensed by the sensors are different, the sensors can be set in different physical spaces of the cloud terminal. For example, sensor 1 can be integrated in the display area of the cloud terminal, and sensor 2 is integrated in the non-display area of the cloud terminal.

[0039] Figure 2 is a flowchart of a data transmission method shown according to an exemplary embodiment of the present disclosure, which is applied to a cloud terminal. As Figure 2 shown, the data transmission method includes the following steps.

[0040] In step S101, it is determined that there is data to be transmitted to the cloud server, and the hardware that generates the data to be transmitted and the hardware category to which the hardware belongs are determined. The hardware category is pre-divided based on the functional attributes of the hardware for generating data.

[0041] In step S102, the target data packet format of the data to be transmitted corresponding to the hardware category is determined.

[0042] In step S103, based on the target data packet format, the data to be transmitted is transmitted to the cloud server.

[0043] In the embodiment of the present disclosure, the cloud terminal transmits data to the cloud server to enable the cloud server to process the data. Among them, the data to be transmitted is generated by the hardware of the cloud terminal. Based on the functional attributes of the hardware for generating data, the hardware categories that generate the data to be transmitted are pre-divided. When determining the data to be transmitted, the hardware that generates the data to be transmitted and the hardware category to which the hardware belongs are determined based on the data to be transmitted.

[0044] The cloud terminal transmits the data to be transmitted to the cloud server based on the set target data packet format. The target data packet format corresponds to the hardware category that generates the data to be transmitted, and different hardware categories correspond to different target data packet formats.

[0045] According to an embodiment of the present disclosure, a cloud terminal transmits data to be transmitted to a cloud server based on a target data packet format, and the target data packet format corresponds to the category of the hardware that generates the data to be transmitted, so as to achieve effective and reliable data transmission from the cloud terminal to the cloud server.

[0046] Figure 3 It is a flowchart of a method for determining a target data packet format of data to be transmitted corresponding to a hardware category according to an exemplary embodiment of the present disclosure. As Figure 3 shown, the method includes the following steps.

[0047] In step S201, determine the hardware sub-category corresponding to the hardware that generates the data to be transmitted. The hardware sub-category is pre-divided based on the functional attributes of the data generated by the hardware under the hardware category, and each hardware category includes one or more hardware sub-categories.

[0048] In step S202, map the hardware category, the hardware sub-category, and the data to be transmitted to the encoded byte positions of data transmission, so as to obtain the target data packet format of the data to be transmitted corresponding to the hardware category.

[0049] In an embodiment of the present disclosure, the cloud terminal transmits data to the cloud server to enable the cloud server to process the data. Among them, the data to be transmitted is generated by the hardware of the cloud terminal. The cloud terminal transmits the data to be transmitted to the cloud server based on the set target data packet format, and the target data packet format corresponds to the hardware category that generates the data to be transmitted. Based on the functional attributes of the data generated by the hardware, pre-divide the hardware category that generates the data to be transmitted, and the hardware sub-categories included under the hardware category. Each hardware category includes one or more hardware sub-categories. Determine the hardware sub-category corresponding to the hardware that generates the data to be transmitted, and the hardware category to which the hardware sub-category belongs.

[0050] In one implementation, the hardware for the cloud terminal to generate data to be transmitted is a sensor set for the cloud terminal, and the data to be transmitted is the detection data corresponding to the sensor. The cloud terminal is provided with multiple sensors, such as optical sensors, magnetic sensors, mechanical sensors, etc. The cloud terminal is provided with multiple sensor categories, and in a certain sensor category, it can include one or more sub-categories. For example, in the optical sensor category, it includes sub-categories such as light sensors, distance sensors, and time-of-flight sensors. For another example, in the magnetic sensor category, it includes sub-categories such as Hall sensors, geomagnetic sensors, and digital sensors. For another example, in the mechanical sensor category, it includes sub-categories such as pressure sensors and micro-mechanical sensors. It is pre-set that the optical sensor category is L, and the sub-categories corresponding to the light sensor, distance sensor, and time-of-flight sensor are L1, L2, and L3 respectively. The magnetic category is M, and the sub-categories corresponding to the Hall sensor, geomagnetic sensor, and digital sensor are M1, M2, and M3 respectively. The mechanical sensor category is F, and the sub-categories corresponding to the pressure sensor and micro-mechanical sensor are F1 and F2 respectively. That is, it is determined that the hardware sub-category corresponding to the Hall sensor data is M1, and the hardware category is M, and the hardware sub-category corresponding to the pressure sensor data is F1, and the hardware category is F.

[0051] In the data packet format, the hardware category, hardware sub-category, and data to be transmitted are mapped to the encoded byte bits of data transmission to obtain the target data packet format of the data to be transmitted corresponding to the hardware category. The target data packet format can include a header byte, a start bit, and an end bit. Among them, the header byte in the data packet format can be used to match the hardware category and the hardware sub-category. Each byte in the data packet format can include eight bit positions. The bit positions can include user id encoding, start bit, end bit, read / write bit, parity check bit, data transmission protocol header bit, and end bit, etc., as well as data bit positions for characterizing data values. After the cloud terminal obtains the sensor detection data, it communicates with the cloud server and sends the sensor data to the cloud server for processing.

[0052] According to the embodiments of the present disclosure, the cloud terminal transmits the data to be transmitted to the cloud server based on the target data packet format. The target data packet format of the data to be transmitted corresponds to the hardware category that generates the data to be transmitted, realizing effective and reliable data transmission from the cloud terminal to the cloud server.

[0053] Figure 4 It is a flowchart of a method for mapping a hardware category, a hardware sub-category, and data to be transmitted to encoded byte bits of data transmission according to an exemplary embodiment of the present disclosure, as Figure 4 shown, the method for mapping a hardware category, a hardware sub-category, and data to be transmitted to encoded byte bits of data transmission includes the following steps.

[0054] In step S301, in response to the hardware subcategories including multiple different hardware subcategories, at least the first hardware subcategory and the second hardware subcategory are included in the multiple different hardware subcategories.

[0055] In step S302, the first hardware subcategory and the first data to be transmitted corresponding to the first hardware subcategory are inserted into the encoded byte bits mapped to the second hardware subcategory and the second data to be transmitted corresponding to the second hardware subcategory according to a preset insertion method.

[0056] In the embodiment of the present disclosure, the cloud terminal transmits data to the cloud server to enable the cloud server to process the data. Among them, the data to be transmitted is generated by the hardware of the cloud terminal. The cloud terminal transmits the data to be transmitted based on a set target data packet format. The target data packet format of the data to be transmitted corresponds to the hardware category that generates the data to be transmitted. Based on the functional attributes of the hardware for generating data, the hardware categories that generate the data to be transmitted and the hardware subcategories included in the hardware categories are pre-divided. Each hardware category includes one or more hardware subcategories. Determine the hardware subcategory corresponding to the hardware that generates the data to be transmitted and the hardware category to which the hardware subcategory belongs.

[0057] In one implementation, the data to be transmitted by the cloud terminal is the detection data corresponding to the magnetic sensor. The hardware category that generates the data to be transmitted is the magnetic sensor set by the cloud terminal. The magnetic sensor category includes subcategories such as the first hardware subcategory Hall sensor and the second hardware subcategory geomagnetic sensor. The first data to be transmitted corresponding to the Hall sensor is the Hall status quantity, and the second data to be transmitted corresponding to the geomagnetic sensor is the magnetic field strength. Among them, the number of data bits occupied by the magnetic field strength can be 8 bits, while the Hall status only corresponds to the on or off state, that is, the Hall status quantity can be represented by only 1 bit. The 1-bit information of the Hall status quantity is randomly inserted into the information mapped to the 8-bit magnetic field strength.

[0058] According to the embodiment of the present disclosure, when mapping the hardware category, the hardware subcategory, and the data to be transmitted to the encoded byte bits of the data transmission, the hardware subcategory includes multiple different hardware subcategories, at least including the first hardware subcategory and the second hardware subcategory. The first data to be transmitted with a relatively small number of occupied data bits is inserted into the encoded byte bits mapped to the second hardware subcategory and the second data to be transmitted corresponding to the second hardware subcategory according to a preset insertion method. The preset method can be a random insertion method. It can reduce the occupancy of multiple data to be transmitted corresponding to multiple subcategories, thereby saving the network bandwidth required for transmitting data, reducing the data transmission time, and random insertion can achieve encrypted transmission of the transmitted data, improving the security of data transmission between the cloud terminal and the cloud server.

[0059] Figure 5It is a flowchart of a method for transmitting data to be transmitted to a cloud server according to an exemplary embodiment of the present disclosure. As Figure 5 shown, the method for transmitting data to be transmitted to a cloud server includes the following steps.

[0060] In step S401, in response to the hardware sub-category corresponding to the hardware that generates the data to be transmitted being multiple and / or the hardware category to which the hardware sub-category belongs being multiple, a cache space for data transmission based on the first-in-first-out cache mechanism is determined.

[0061] In step S402, the data to be transmitted is stored in the cache space.

[0062] In step S403, in response to the cache space being filled, the data to be transmitted is transmitted to the cloud server.

[0063] In the embodiment of the present disclosure, the cloud terminal transmits data to the cloud server to enable the cloud server to process the data. Among them, the data to be transmitted is generated by the hardware of the cloud terminal. The cloud terminal transmits the data to be transmitted to the cloud server based on the set target data packet format. The target data packet format of the data to be transmitted corresponds to the generated hardware category.

[0064] In the embodiment of the present disclosure, the cloud terminal can be a microcontroller unit that determines a cache space for data transmission based on the first-in-first-out (FIFO) cache mechanism, increases the data transmission rate, and facilitates the processing of a large amount of data streams. When the hardware sub-category corresponding to the hardware that generates the data to be transmitted is multiple, and / or the hardware category to which the hardware sub-category corresponding to the hardware that generates the data to be transmitted belongs is multiple, data transmission is performed based on the FIFO cache mechanism. Multiple data to be transmitted generated by multiple hardware are stored in the FIFO. The number of data bits in the FIFO cache space is determined based on the sum of the data bit quantities occupied by the data to be transmitted. When the FIFO cache space is filled, the microcontroller unit transmits the data to be transmitted to the cloud server, that is, operations such as encoding, encrypting, and encapsulating the data to be transmitted in the cache space are performed, and modulation and carrier are performed with the communication modem for radio frequency transmission to the cloud server.

[0065] For example, the number of multiple data to be transmitted corresponding to multiple hardware sub-categories, or multiple data to be transmitted corresponding to multiple hardware categories is n. The total sum of the data bit quantities occupied by n data to be transmitted is sum n . That is, a FIFO cache space is determined in the microcontroller unit, and the space capacity is sum n bits. The n data to be transmitted are stored in the FIFO. When the storage bits of the FIFO are filled, it is determined that the n data to be transmitted are transmitted to the cloud server.

[0066] According to an embodiment of the present disclosure, a cache space for data transmission based on a first-in-first-out cache mechanism is determined, and the data to be transmitted is stored in the cache space. When the cache space is filled, the data to be transmitted is transmitted to the cloud server, improving the data transmission efficiency and reducing the resource occupancy of the transmitted data.

[0067] Figure 6 FIG. is a flowchart of a method for storing data to be transmitted in a cache space according to an exemplary embodiment of the present disclosure. As Figure 6 shown, the method for storing data to be transmitted in a cache space includes the following steps.

[0068] In step S501, for each hardware sub-category corresponding to the data to be transmitted and / or the polling frequency corresponding to the hardware category, the data to be transmitted corresponding to the hardware sub-category and / or the hardware category is obtained based on the minimum polling frequency.

[0069] In step S502, the obtained data to be transmitted is stored in the cache space.

[0070] In an embodiment of the present disclosure, the cloud terminal transmits data to the cloud server to enable the cloud server to process the data. Among them, the data to be transmitted is generated by the hardware of the cloud terminal. The cloud terminal transmits the data to be transmitted to the cloud server based on a set target data packet format. The target data packet format of the data to be transmitted corresponds to the hardware category that generates the data to be transmitted. When there are multiple hardware sub-categories corresponding to the hardware that generates the data to be transmitted and / or multiple hardware categories to which the hardware sub-categories corresponding to the hardware that generates the data to be transmitted belong, the data to be transmitted corresponding to multiple hardware sub-categories and / or multiple hardware categories is transmitted. The data packet format of the data to be transmitted includes the data bit positions of the data value, as well as the user ID code, start bit, end bit, read / write bit, parity check bit, data transmission protocol header bit, and end bit, etc. The increase in the number of transmissions consumes computing resources, increases the transmission time, and increases the occupancy of the bandwidth and communication channels.

[0071] In an embodiment of the present disclosure, for each hardware sub-category corresponding to the data to be transmitted and / or the polling frequency corresponding to the hardware category is determined. For example, the polling frequencies of the hardware data corresponding to n data to be transmitted are f 1 、f 2 、f 3 ……f n . The microcontroller unit of the cloud terminal polls the polling frequencies of n hardware. It can be understood that the minimum polling frequency corresponds to the maximum polling period. Based on the minimum polling frequency, that is, the data to be transmitted corresponding to the hardware sub-category and / or the hardware category is obtained with the longest polling period, and the obtained data to be transmitted is stored in the cache space. This can not only ensure the effective acquisition of the data to be transmitted, but also avoid the waste of resources caused by multiple acquisitions of the data to be transmitted.

[0072] According to an embodiment of the present disclosure, determine the polling frequency corresponding to each hardware subcategory and / or hardware category of the data to be transmitted, and based on the minimum frequency among the polling frequencies, obtain the data to be transmitted corresponding to the hardware subcategory and / or hardware category, and store the obtained data to be transmitted in a buffer space, reducing the number of transmissions of multiple data to be transmitted and saving network resources.

[0073] Figure 7 is a flowchart of a method for storing data to be transmitted in a buffer space shown according to an exemplary embodiment of the present disclosure, as Figure 7 shown, the method for storing data to be transmitted in a buffer space includes the following steps.

[0074] In step S601, determine the polling frequency corresponding to each hardware subcategory and / or hardware category of the data to be transmitted.

[0075] In step S602, based on the minimum frequency among the polling frequencies, when it is determined that the data volume corresponding to the data to be transmitted corresponding to the hardware subcategory and / or hardware category is greater than a preset data volume threshold, obtain the data to be transmitted corresponding to the hardware subcategory and / or hardware category.

[0076] In step S603, store the obtained data to be transmitted in a buffer space.

[0077] In an embodiment of the present disclosure, the cloud terminal transmits data to the cloud server to enable the cloud server to process the data. Among them, the data to be transmitted is generated by the hardware of the cloud terminal. The cloud terminal transmits the data to be transmitted to the cloud server based on a set target data packet format, and the target data packet format of the data to be transmitted corresponds to the hardware category that generates the data to be transmitted. When there are multiple hardware subcategories corresponding to the hardware that generates the data to be transmitted, and / or when there are multiple hardware categories to which the hardware subcategories corresponding to the hardware that generates the data to be transmitted belong, transmit the data to be transmitted corresponding to multiple hardware subcategories and / or multiple hardware categories.

[0078] In an embodiment of the present disclosure, determine the polling frequency corresponding to each hardware subcategory and / or hardware category of the data to be transmitted. For example, the polling frequencies of the hardware data corresponding to n data to be transmitted are respectively f 1 、f 2 、f 3 ……f n。The micro - control unit of the cloud terminal polls the polling frequencies of n hardware components. Understandably, the minimum polling frequency corresponds to the maximum polling period. Based on the minimum polling frequency, that is, obtaining the data to be transmitted corresponding to the hardware sub - category and / or hardware category with the longest polling period. A data volume threshold for the data to be transmitted corresponding to the preset hardware sub - category and hardware category is set. When it is determined that the data volume of the data to be transmitted corresponding to the hardware sub - category and hardware category is greater than the preset data volume threshold, the data to be transmitted is obtained. That is, when the data volume of the data to be transmitted does not exceed the preset data volume threshold, the hardware is in the interrupt mode, the hardware that generates the data to be transmitted has not completed the data update, and the data to be transmitted is not obtained, reducing the number of data transmissions. When the data volume of the data to be transmitted is greater than the preset data volume threshold, the micro - control unit of the cloud terminal obtains the data to be transmitted and stores it in the cache space.

[0079] According to an embodiment of the present disclosure, the polling frequency corresponding to each hardware sub - category and / or hardware category of the data to be transmitted is determined, and based on the minimum polling frequency, when it is determined that the data volume of the data to be transmitted corresponding to the hardware sub - category and / or hardware category is greater than the preset data volume threshold, the data to be transmitted corresponding to the hardware sub - category and / or hardware category is obtained and stored in the cache space, reducing the number of transmissions of multiple data to be transmitted and saving network resources.

[0080] Figure 8 is a flowchart of a data transmission method shown according to another exemplary embodiment of the present disclosure, as Figure 8 shown, the data transmission method includes the following steps.

[0081] In step S701, it is determined that there is data to be transmitted to the cloud server, and the hardware that generates the data to be transmitted is determined.

[0082] In step S702, the target data packet format of the data to be transmitted corresponding to the hardware category is determined.

[0083] In step S703, based on the target data packet format, in response to the fact that there are multiple hardware sub - categories corresponding to the hardware that generates the data to be transmitted and / or there are multiple hardware categories to which the hardware sub - categories belong, the data to be transmitted of multiple hardware sub - categories and / or hardware categories is transmitted to the cloud server in a random sorting manner.

[0084] In the embodiments of the present disclosure, a cloud terminal transmits data to a cloud server to enable the cloud server to process the data.

The microcontroller unit of the cloud terminal randomly determines an arrangement mode among the arrangement modes, and uses the determined arrangement mode as a part of the data to be transmitted and transmits it to the cloud server. The cloud server and the cloud terminal share the corresponding arrangement mode sorting. The cloud server receives the data transmitted by the cloud terminal, obtains the arrangement mode at the corresponding data bit in the data, and decrypts the received data, further ensuring the security of data transmission.
