[0074] Furthermore, the output signal of the transistor-transistor logic circuit interface includes an RGB data signal, a clock signal and a control signal.

[0075] In order to deeply understand the composition structure of a resource extension protocol provided by the present invention, this article also defines the main format of the extension protocol mentioned in more detail.

[0076] Furthermore, the resource extension protocol in the present invention belongs to the electronic communication industry and is applied to the fields of microelectronic communication technology and computer science and technology. It is a type of network communication protocol and therefore has the main properties and characteristics of a network communication protocol.

[0077] Refer to the attached Figure 3 Specifically, there are 6 types of data types, namely: 1. Transparent transmission (marked as 0x01), used to support transparent transmission of AT commands, upgrades, 101 protocols, etc.; 2. Read time (0x02), that is, the time when the main module reads the extension module; 3. Write time (0x03), that is, the time when the main module sets the extension module; 4. Read parameters (0x04), that is, the main module reads the module extension and its global positioning system GPS, long-distance radio half-duplex wireless data transmission module LoRa, Bluetooth, etc. data; 5. Write parameters (0x05), that is, the main module sets the module extension and its GPS, LoRa, Bluetooth, etc. data; 6. Running status (0x06), that is, the main module notifies the extension module of its current running status.

[0078] Specifically, the AT command refers to a computer program instruction sent from a terminal equipment (TE) or a data terminal equipment (DTE) to a terminal adapter (TA) or a data circuit terminal equipment (DCE).

[0079] Specifically, the 101 protocol is a more popular communication protocol, which mainly includes the protocol structure, physical layer, link layer, and application layer. Specifically for the 101 protocol, the provisions for the physical layer are selected from ISO and ITU-T standards. The standard supports the following network structures, including point-to-point, multiple point-to-point, multi-point star, multi-point co-linear, multi-point ring, etc. In terms of electrical characteristics, V.24 / V.28 is used for unbalanced switching circuits, while X.24 / X.27 is used for balanced switching circuits.

[0080] Refer to the attached Figure 4 There are three definitions of transmission reasons. The ones in brackets in this paragraph are the identification of transmission reasons, which are: activation (0x06) is used for data request, activation confirmation (0x07) is used for data response, and activation denial (0x08) is used to indicate data abnormality or failure.

[0081] Refer to the attached Figure 5 There are 6 definitions of data channels, namely: 1. The local serial port channel of the main module or the expansion module itself (0x00); 2. The peripheral channel data of the non-expansion module (0x01), which means that the main module actively sends data to the expansion module; 3. Lora channel (0x02); 4. Bluetooth channel (0x03); 5. Ethernet channel (0x04); 6. 4G channel (0x05).

[0082] Refer to the attached Figure 6 There is a definition of the data area, whose message content is the data content DATA, the byte length is set to X, and its digital bit length is variable, reflecting its own data content.

[0083] Furthermore, the resource extension protocol mentioned above, as a computer language structure applied to the software part of the electronic communication system, refers to the rules and agreements that both entities must follow to complete communication or services. This extension protocol defines the format used by the data unit, the information and meaning that the information unit should contain, the connection method, and the timing of information sending and receiving, so as to ensure that the data in the network is smoothly transmitted to the determined address.

[0084] Furthermore, a resource extension protocol applied in the present invention is mainly composed of the following three elements: syntax, that is, how to communicate, including the format, encoding and signal level (electrical level) of data; semantics, that is, the content of communication, including data content, meaning and control information; timing rules (timing): that is, when to communicate, clarifying the order, rate matching and sorting of communication.

[0085] Furthermore, in the above-mentioned practical application examples of the present invention, the transmission of all data in the communication system is completed by the resource extension protocol.

[0086] Furthermore, in the actual application of this resource extension protocol in this field, due to the hierarchical, reliable and effective properties of the communication protocol, it greatly optimizes the data transmission and analysis processing between multiple different communication terminals in the network domain, and realizes long-distance interconnection between multiple communication devices.

[0087] In addition, specifically, in this embodiment of the present invention, by adding the use of the subsequent expansion module, the original finished module has only 2 maintenance interfaces, which is expanded to 5 maintenance and debugging channels, and the data channel has been increased from the original 3 channels (Ethernet, SFP, 4G) to 1 Ethernet data channel, and 3 FLASH chips have been expanded to store data, a GNSS positioning function has been added, and the LED module light group GPIO expansion has been added.

[0088] Furthermore, GNSS refers to the Global Navigation Satellite System. The positioning of the Global Navigation Satellite System uses a set of satellite pseudoranges, ephemeris, satellite launch time and other observations, and must also obtain the user's clock error. The Global Navigation Satellite System is an air-based radio navigation positioning system that can provide users with all-weather 3D coordinates, speed and time information at any location on the Earth's surface or near-Earth space.

[0089] Furthermore, for GPIO expansion, in embedded systems, it is often necessary to control many external devices or circuits with simple structures. Some of these devices need to be controlled by the central processing unit CPU, and some need the CPU to provide input signals. In addition, many devices or circuits only require two states of on / off, such as the on and off of LEDs. The control of these devices using traditional serial ports or parallel ports is more complicated, so a "general programmable I / O port", also known as GPIO, is provided on embedded microprocessors.

[0090] In the practical application example of the present invention, specifically, a GPIO port requires at least two registers, a "general I / O port control register" for control, and a "general I / O port data register" for storing data. Each bit of the data register corresponds to the hardware pin of the GPIO, and the data transmission direction is set by the control register, and the data flow direction of each pin can be set by the control register.

[0091] Through the application of the present invention, a resource extension protocol provided by the present invention on the basis of the original communication protocol realizes the interconnection and interoperability of data transmission between wireless communication modules, and effectively reduces the difficulty of rapid secondary development of wireless communication modules; by adding a post-stage expansion module, the flexibility of the original product is increased, and on the basis of the mature use of the original product, the cycle of secondary development is reduced, the development efficiency of the product is improved, and the existing technical problems in this field are well solved.

[0092] It should be noted that, in this article, the terms "include", "comprises" or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the above elements, but also other elements that have not been explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0093] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases, the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for a terminal device (including but not limited to a mobile terminal, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods of various embodiments of the present invention.

[0094] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
