Description
Technical Field
The invention belongs to the field of communication of the Internet of things, and particularly relates to a reverse docking method and device for an IOT protocol.
Background
With the continuous development of communication technology, computer technology and electronic technology, mobile communication is developing from Human-to-Human (Human-to-Human, H2H) to Human-to-animal (Human-to-Machine, H2M) and object-to-object (Machine-to-Machine, M2M) communication, and the interconnection of everything becomes a necessary trend of mobile communication development. The Internet of Things (IOT) is a forthcoming feature in this context, which is considered to be the third wave of the world information industry after the computer and Internet. The Internet of things adopts an information technology means, promotes the comprehensive upgrade of human life and production service, and has wide application and development prospect and strong industry driving capability. The European and American countries have brought development of the Internet of things into the whole information strategy, and China has also brought the Internet of things into the national middle and long-term scientific and technical development plans (2006-2020) and the 2050 national industry roadmap. In 1999, the automatic Identification center (Auto-ID Labs) of MIT (massachusetts institute of technology) first proposed the concept of the internet of things, which means that all articles are connected to the internet through Radio Frequency Identification (RFID) and other information sensing devices to realize intelligent Identification and manageable network.
When the intelligent equipment needs to access the cloud SAAS service in the Internet of things, the equipment needs to be ensured to be normally connected to the cloud server, and the equipment can normally communicate with the cloud server. For the networking problem, only an over-stable networking module needs to be provided, but the device and the cloud server need to have a uniform communication protocol when the device needs to communicate with the cloud server. For the intelligent device protocol, no special organization exists to customize the protocols (such as the international standards of TCP protocol and HTTP protocol). So the current protocols are mainly provided by SAAS service providers or smart device providers. If one of the SAAS service provider or the intelligent equipment provider has a mature protocol, the other party only needs to cooperate with the protocol to develop and interface. However, when both the SAAS service provider and the smart device provider have their own mature communication protocols, a conflict occurs, and both hopes that the other party adopts their own protocols. At this time, a completely new docking mode is required to adapt to the situation.
As a platform-type SAAS service provider, it is necessary to adapt to a motherboard protocol customized by each smart device provider. If each mainboard manufacturer needs a specially customized protocol conversion service, the whole system becomes large and bloated, the later maintenance cost becomes large, and a corresponding server is needed to be deployed, so that the cost of the machine is increased. Because the steps of protocol understanding, development, testing, deployment and the like are required before each protocol conversion service is online, the whole docking period is prolonged, the docking cost is increased, and the online risk is increased. In view of the above problems, no effective solution has been proposed.

Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 7 in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As a platform-type SAAS service provider, it is necessary to adapt to a motherboard protocol customized by each smart device provider. If each mainboard manufacturer needs a specially customized protocol conversion service, the whole system becomes large and bloated, the later maintenance cost becomes large, and a corresponding server is needed to be deployed, so that the cost of the machine is increased. Because the steps of protocol understanding, development, testing, deployment and the like are required before each protocol conversion service is online, the whole docking period is prolonged, the docking cost is increased, and the online risk is increased. As shown in fig. 1, the present invention thus provides a specialized reverse docking protocol resolution technique. Through the technology, the platform can be adapted to most mainboard protocols with custom formats in the market at the same time. The docking personnel only need to know the protocol and configure corresponding protocol content in the system according to the corresponding protocol, so that the whole docking process is simplified, the whole docking period is shortened, risks caused by steps of opening, testing, deploying and the like are reduced, and the machine cost for deploying other services is reduced.
By analyzing the protocols provided by main intelligent equipment providers in the market, the main format of the protocol in the market at present is byte stream, and byte contents in the format of the byte stream mainly comprise a frame head, a frame tail, length bits, check bits, specific data contents, instruction identification bits and the like. Byte stream format data refers to continuous stream data that does not contain boundary data, and the data content is composed of bytes. The byte content mainly comprises a frame head, a frame tail, length bits, check bits, specific data content, instruction identification bits and the like. The frame header is one or several fixed data contents for transmitting the beginning of a section of byte data and is used for indicating the beginning of the data. The end of frame is one or several fixed data contents for transmitting the end of a section of byte data and is used for indicating the end of data. The length bit is specially used for representing the length content of byte data and is mainly used for truncating the data content of a section of byte stream. The check bits are specially used for checking byte stream data, and data errors caused by interference of the data in a network transmission process are prevented. The instruction identification bit is mainly used to identify which specific command the instruction belongs to, and as shown in fig. 4, is a flow chart of parts of byte stream format data in protocol parsing and protocol assembling according to the present invention.
However, in data docking, because the data expression process of the byte stream is not clear enough, the meaning expressed by the byte stream cannot be directly known, and actually, in the interaction of the current server, the environment of the whole internet is relatively stable, the contents such as flow and verification do not need to be considered basically, and the problem needs to be treated in a simpler mode. Therefore, the JSON format character string data is adopted in the process of exchanging with the server, and general technicians can see the meaning expressed by the corresponding instruction through the data, so that the processing flow of the server is simplified. In the data in JSON format, the byte content mainly consists of an instruction identification bit and specific data content, as shown in fig. 5, which is a flow chart of each part of the JSON format data in protocol parsing and protocol assembly.
Based on the above situation, as shown in fig. 1, an embodiment of the present invention provides an IOT protocol reverse docking method, which includes two modes:
as shown in fig. 2, the first mode is that a terminal device between different protocols sends an instruction to a server, in this mode embodiment, a source control main body is the terminal device, a target control main body is the server, terminal device instruction content data is data in a byte stream format, and server instruction content data is data in a JSON format. The method comprises the following specific steps:
s101, receiving source protocol instruction content data sent by a source control main body, and checking data validity;
and receiving source protocol instruction content data sent by a source execution main body (namely the terminal equipment), and checking the validity of the data.
Further, the checking the validity of the instruction content data includes: and checking whether the head, tail, length bit and check bit data of the instruction content data are legal or not.
S102, illegal data in the instruction content data are processed to be legal.
In the embodiment of the present invention, if the result of verifying the data is illegal, basically, a sticky packet is removed, and sticky packets are two cases caused by the fact that the data content is inconsistent with the cache size on the network card of the sender or the receiver in the data transmission process: one situation is unpacking, i.e. a data content may be sent out in several packets; another case is sticky-packaging, i.e. a data packet is sent out that contains several data contents.
In the embodiment of the invention, the step of processing the illegal data in the instruction content data to be legal refers to the step of forwarding the illegal data content to a de-bonding package service to be de-bonded and bonded so as to be legal.
S103, when the instruction content data is legal, extracting the data content and the instruction identification bit.
In the embodiment of the invention, based on the verification of the frame head, the frame tail, the length bit and the check bit data of the instruction content data, when the instruction content data is legal, the data content and the instruction identification bit are extracted, wherein the instruction identification bit is mainly used for identifying which specific command the instruction belongs to.
S104, analyzing data content by matching the extracted instruction identification bits with specific protocol commands;
in the embodiment of the invention, the specific protocol command is matched based on the extracted specific data content and the instruction identification bit, and then the specific data content is analyzed.
S105, according to the target protocol requirement, performing data conversion on the analyzed data content to enable the data to be matched with the target protocol instruction data;
in the embodiment of the invention, based on the difference of the expression meanings of the data in the source protocol instruction and the target protocol instruction, the data needs to be converted according to the instruction meaning required by the target protocol before the instruction is reassembled.
In the process of reassembling the instruction, because the meaning of some data expressed in different instructions is different, for example, the motherboard startup result 0 indicates success, and 1 indicates failure, but the server side startup result 1 indicates success, and 0 indicates failure, based on which the motherboard startup result should be converted from 0 to 1, and 1 to 0, and then the result should be transmitted to the server side, therefore, some data conversion should be performed before assembling the instruction.
And S106, assembling the converted data to enable the converted data to become instruction content data meeting the requirements of the target protocol, and sending the instruction content data to the target execution main body.
In the embodiment of the invention, based on the converted data content, the data is assembled according to the data format defined by the JSON instruction, the corresponding data content is filled, the original instruction content is reassembled into a target protocol instruction content, and the target protocol instruction content is sent to a target execution main body (server).
As shown in fig. 3, the second mode is that a server between different protocols sends an instruction to a terminal device, in this mode embodiment, a source control main body is the server, a target control main body is the terminal device, terminal device instruction content data is data in a byte stream format, and server instruction content data is data in a JSON format. The method comprises the following specific steps:
s201, receiving source protocol instruction content data sent by a source control main body, and extracting data content and an instruction identification bit;
in the embodiment of the invention, the source protocol instruction data sent by the source execution main body (namely the server) is received, and the data content and the instruction identification bit are directly extracted without checking the data validity and processing illegal data in the instruction data because the server instruction content data is JSON (Java Server connection) format data.
S202, analyzing data content by matching the extracted instruction identification bits with specific protocol commands;
in the embodiment of the invention, the specific protocol command is matched based on the extracted specific data content and the instruction identification bit, and then the specific data content is analyzed.
S203, according to the target protocol requirement, data conversion is carried out on the analyzed data content, and the data are made to be adaptive to the target protocol instruction data;
in the embodiment of the invention, based on the difference of the expression meanings of the data in the source protocol instruction and the target protocol instruction, the data needs to be converted according to the instruction meaning required by the target protocol before the instruction is reassembled.
In the process of reassembling the instruction, because the meaning of some data expressed in different instructions is different, for example, the motherboard startup result 0 indicates success and 1 indicates failure, but the server side startup result 1 indicates success and 0 indicates failure, some data conversion should be performed before assembling the instruction.
S204, the converted data is assembled to form instruction content data meeting the requirements of the target protocol;
in the embodiment of the invention, based on the converted data content, filling the corresponding data content according to the byte stream format of the target protocol; then increasing the contents of a frame head and a frame tail; calculating length bit data and check bit data; and filling each item into a new instruction; and the reassembly of the source protocol instruction content into target protocol instruction data is completed.
And S205, after the data are assembled, sending the data to a target execution body.
In the embodiment of the invention, the assembled target protocol instruction data is sent to a target execution main body (terminal equipment).
The following is an example of a specific implementation: the terminal equipment sends a content instruction for finishing reporting the instruction to the server, and simultaneously after the terminal equipment reports the instruction, the server sends a response instruction to the terminal equipment, and the operation process is as follows:
receiving a byte stream format instruction reported by the terminal equipment:
aa152c01010000000a00000000001e00000400000f3f19
checking whether the frame head, the length bit and the check bit data are legal or not, and extracting and processing the data content after the validity is confirmed as follows:
aa2c01010000000a00000000001e00000400000f3f
and recognizing the instruction as a charge ending state (background starting) instruction according to the instruction identification bit.
According to the format defined by the submit charge end state (background start) instruction, the contents are extracted as follows:
{"result":[1],"head":[-86],"PORT":[1],"ELEC":[0,10],"CARD_TYPE":[0],"CARD_ID":[0,0,0,0],"TIME":[0,0],"cmd":[44],"SESSION_ID":[0,0,15,63],"REASON":[4],"CARD_OPE":[0],"CARD_CST":[0,30]}。
and judging whether an instruction needs to be sent to the server side or not, and knowing that the instruction needs to send a CHARGING END related instruction (the corresponding instruction code is CDZ _ AK _ CHARGING _ END) to the server side according to the configuration.
And converting the extracted content into data content which needs to be sent to a server, and sending JSON instruction data out. And if the information needs to be responded to the main board, the information is converted again according to the content extracted before, and then the information is assembled into a new direct instruction to be issued again.
