Description
Technical Field
The invention relates to the technical field of intelligent Internet of things construction, in particular to an Internet of things equipment integration system based on a mapping file.
Background
In the field of intelligent Internet of things construction, hardware equipment with a networking function is various in types. A huge device group comes from different hardware manufacturers, and each device group has a unique software environment and a unique data background. But overall, the method for accessing the internet of things device by a general user is similar, and a basic system model for accessing the internet of things device is shown in fig. 1. In this system model, three components are mentioned:
1. internet of things equipment located in specific equipment installation environment
2. Internet-based [ device access data platform ] is generally provided by device manufacturers
3. Device access operation interface for end user
Internet of things (lot) devices produced by device manufacturers are immutable objects with fixed functions and provided to users as final stable products. Although most devices are purchased and then put into use, and there may be processes for device installation and maintenance in a particular environment, these matters are generally relatively well-defined entity elements either because of their simplicity, their discretion by the user, or their responsibility within the manufacturer's lot of devices.
In the process that an end user accesses the equipment of the Internet of things, the actual end is directly faced with an equipment access operation interface; before the interface is contacted, an internet-based [ device access data platform ] is generally needed to realize basic function management of the target device. The two elements are the most different from the device in that the device is a physically present entity, and the two are software services in nature.
Admittedly, equipment manufacturers can take the equipment access data platform and the equipment access operation interface as the functions matched with the Internet of things equipment products, or directly or indirectly provide the functions for users, so as to achieve the closed loop of the Internet of things system; however, in this link, the [ device access operation interface ] that the end user contacts is not provided only by the manufacturer. In the prior art, a closed loop of an internet of things system can be formed in various ways, and a main implementation manner is shown in fig. 2.
In the practical application process, one user may need to purchase various physical devices, which is inevitable; but as a software service, it is not as simple as "more and better". The situation for this problem is: under the environment of a single Internet of things device, a device manufacturer can directly provide a device access operation interface for an end user, and the requirement of a single device user can be generally met; even though the user uses a plurality of or a plurality of devices, the devices are provided by the same manufacturer, so the device access operation interface provided by the device manufacturer can also incorporate the devices. The schematic diagram of the situation that the simultaneous existence of multiple internet of things devices from different manufacturers makes the end user face a plurality of devices to access the operation interface is shown in fig. 3. If the internet of things device environment where the user is located is not a single device any longer, not only the devices of one manufacturer but also multiple types of devices from different device manufacturers, in order to access multiple internet of things devices operating in the same device installation environment, the user may need to simultaneously contact and use multiple different sets of devices (device access operation interfaces), which undoubtedly brings great inconvenience to the daily use of the user. In this case, a "unified" device access operation interface is required to be the most desirable target for such users.
The method provides a uniform equipment access operation interface for the management of various Internet of things equipment of multiple manufacturers by an end user, and can be started from the following modes:
1. the user self-develops an interface meeting the self-demand based on the SDK provided by the manufacturer (the application technology threshold of the user is raised)
2. Seeking to concentrate on the integrator of the integrated service, to make a customized service to assist the solution (the user needs to pay extra high funds)
3. An existing and flexibly extensible integration platform is sought to carry out relatively simple self-defined integration so as to achieve the aim (the user needs to pay extra and less funds to achieve the aim)
The common point of the three modes is that the equipment access operation interface originally provided by the manufacturer is not used, and the equipment access operation interface is customized through different channels. Only by doing so can the problem be solved how the access operations from devices of different vendors are "unified". The users self-research and search integrators, which are essentially the same, need someone to integrate devices of different manufacturers, or do the integration by themselves or spend money for a person, and the result is that the end users pay more cost. And an existing 'integration platform' technically unifies the work, reusability of development investment is improved, and an end user only needs to spend little cost, namely the end user is customized compared with self-research and all entrusted integration merchants, which is undoubtedly the most friendly scheme for the end user. However, how to obtain an internet of things device integration mode with strong flexibility and strong expansibility is an urgent problem to be solved.

Compared with the prior art, the internet of things equipment integration system based on the mapping file provided by the embodiment can acquire the equipment target data of the internet of things equipment and store the acquired equipment target data in the form system by designing the mapping file used for indicating the equipment access interface information of the single internet of things equipment and utilizing the mapping file analysis system. Therefore, the integrated system in the embodiment has stronger flexibility and expandability; the implementation process is simple and efficient, so that the access cost of the Internet of things equipment can be reduced to the greatest extent; in addition, the integration system has high customization degree, and can achieve the best integration effect under the condition of lower cost.
The mapping file is the core for implementing the scheme in this embodiment, and therefore, the following description is first made for the mapping file:
when a manufacturer of the internet of things equipment wants to access the internet of things equipment through the equipment access data platform, equipment access interface information needs to be recorded: the manufacturer must cooperate with the parameters of the internet-of-things device to connect to the corresponding internet-of-things device according to a given network data interface (possibly with corresponding network protocol information). In the mapping file, the manufacturer needs to record the device access interface information. In order to enable different internet of things devices produced by different manufacturers to uniformly record device access interface information in a relatively simple and uniform manner, the device access interface information in the mapping file must also be provided in a uniform and agreed format (for example, in JSON text), and includes the following contents:
1. accessing interface configuration information, including: the following necessary options: accessing the interface address and the security verification information; optional items: specifying device data parameters; wherein,
the access interface addresses must be unified in a relatively universal and secure network protocol (e.g., https post); the equipment access interface platform of the equipment of the Internet of things can be linked through the access interface address.
The security verification information is used for accessing the device access interface platform, and illustratively, the security verification information may be a user access key, or an access token is generated based on the security verification information and the device unique identifier, so as to improve the access efficiency of the device access interface platform;
specifying device data parameters indicating parameter requirements for device target data that needs to be extracted, e.g., collecting data for a certain period of time, collecting data that exceeds a certain threshold, etc.
2. The equipment identification information comprises an equipment type unique identifier and an equipment unique identifier; wherein,
the unique equipment type identifier is used for uniquely identifying the equipment type of the current Internet of things equipment;
the unique equipment identifier is used for uniquely identifying the identification information of the equipment of the Internet of things equipment under the current equipment type;
the unique device type identifier and the unique device identifier are uniquely set by a manufacturer, and one piece of Internet of things device can be distinguished from other pieces of Internet of things device through the unique device type identifier and the unique device identifier.
3. A data format for an access interface comprising:
the data structure is used for describing key fields related to the device target data of the Internet of things device;
and the data structure unique identifier is used for uniquely identifying the data structure based on the equipment type unique identifier.
In addition, to further expand the functions of the integrated system, the device access interface information may further include the following:
4. data state alarm information; the data state alarm information comprises alarm fields and alarm conditions of each alarm field; wherein,
setting one or more key fields in the data structure as the alert field;
setting corresponding alarm conditions for each alarm field;
5. an access cycle;
the mapping file analyzing system periodically analyzes the mapping file according to the access period;
the device access interface information is information provided by a hardware manufacturer to create a corresponding "mapping file" for the device. The contents in the device access interface information are organized by some relatively simple structure (e.g. a text file in JSON format) to facilitate filling out by hardware manufacturers. That is, the contents in the mapping file are organized according to a convention format.
Here, the following description is also made of the mapping file stored in the cloud file system:
a mapping file of the Internet of things equipment is used as a computer file, and a file system is needed to manage the mapping file at a file level in the whole system. Because the internet of things device connection must pass through the internet to realize the functions of the internet of things device connection, the file system must also be a cloud file system. In the cloud file system, a device mapping file represents an actual physical hardware device — as long as an end user uploads and stores a valid device mapping file to a cloud disk, the end user can interface and manage access to the hardware device in the cloud file system (unless the device corresponding to the mapping file is offline or the data of the mapping file is incorrect).
As a cloud file system, the system has a basic file management function. Meanwhile, the file online display function is also supported: namely, the file is directly opened in the cloud file system without downloading. In the method, the management platform integrates the butted hardware equipment as if managing each file in the file system:
uploading and storing a mapping file, namely establishing connection with the Internet of things equipment indicated by the mapping file;
deleting a mapping file, namely disconnecting the connection with the Internet of things equipment indicated by the mapping file;
and opening a mapping file, opening a console of the equipment, and performing real-time control (the mapping file needs to contain a corresponding interface).
In this embodiment, when the mapping file analysis system monitors that a new mapping file is added to the cloud file system, the mapping file analysis system starts to analyze the new mapping file; when the mapping file analysis system monitors that the mapping file stored in the cloud file system is deleted, stopping executing analysis of the deleted mapping file; specifically, the mapping file parsing system parses the mapping file by performing the following operations:
1. analyzing the content of the mapping file; in particular, the amount of the solvent to be used,
the mapping file analyzing system analyzes the contents in the mapping file by executing the following operations:
carrying out format verification on the mapping file according to the agreed format;
if the format passes the verification, analyzing each content in the mapping file;
otherwise, prompting to report error and stopping the analysis of the mapping file.
2. And analyzing the device target data associated with the mapping file, wherein the analyzing comprises the following steps:
(1) sending the analyzed data format to a form system so that the form system can obtain a form template matched with the data format; the process is relatively simple and will not be described too much.
(2) Acquiring equipment target data of the Internet of things equipment according to the analyzed access interface configuration information and the equipment identification information, and sending the equipment target data to a form system; in particular, the amount of the solvent to be used,
the acquiring of the device target data of the internet of things device according to the access interface configuration information includes:
reading the access interface address and linking to an equipment access interface platform;
generating a device interface request using the security authentication information and the device unique identifier; the equipment interface request is used for inquiring equipment data of current Internet of things equipment;
if the equipment interface request is successful, the mapping file analysis system acquires the equipment data from the equipment access interface platform and extracts the equipment target data from the equipment data.
If the equipment interface request is wrong and the equipment is not available or the authority is invalid, marking the current Internet of things equipment as an invalid state, and interrupting the target data analysis of the equipment;
otherwise, marking the current Internet of things equipment in an offline state, and taking the obtained latest equipment data of the current Internet of things equipment in the offline state as the equipment target data.
In addition, if the access interface configuration information does not include the specified device data parameters, the latest data in the device data is directly extracted as the device target data; and if not, extracting the equipment data meeting the parameter requirement of the specified equipment data as the equipment target data.
In addition, in order to reduce unnecessary program execution, when the device target data associated with the mapping file is analyzed, whether the internet of things device is in an effective state or not can be judged on the basis of the analyzed device identification information, and if yes, the analyzed data format is sent to the form system; otherwise, the device target data parsing is interrupted.
In addition, after the form system stores the equipment target data in the form template, the form system also feeds back the equipment target data to a mapping file analysis system to finish the storage of the equipment target data; after receiving the storage of the finished equipment target data fed back by the form system, the mapping file analysis system judges whether a next access cycle exists, and if so, executes the analysis of the equipment target data associated with the mapping file again when the next access cycle is reached; otherwise, the device target data analysis related to the current mapping file is not executed.
Next, the form system in the present embodiment is described as follows:
the form is a system which can design a template of a form field, and then form instance data according to the form template to form a form with an uncertain data format. The form system is a common software system, and can well support various data, especially in the process of integrating internet of things devices, when various different devices face and the device data with different data structures needs to be stored, the form system is very necessary. The custom form in the form system needs to support the data types (character strings, integers, floating point numbers, enumerated values, embedded pictures, embedded sound files and the like) of common equipment state information, and supports format matching search form templates (used for corresponding interface requests and storage of different equipment data), and under a specific form template, data addition, deletion, modification and check of form instance data (forms) are performed, and the state information of each equipment is acquired and recorded in real time in cooperation with the equipment access interface analysis function in the mapping file analysis system.
In this embodiment, the form system mainly performs two operations:
1. after receiving a data format sent by a mapping file analysis system, obtaining a form template matched with the data format; in particular, the amount of the solvent to be used,
the form system inquires whether a form template with the same data structure unique identifier is stored in the form system according to the data structure unique identifier,
if the form template is stored, recording the form template as a form template matched with the data format; and if not, creating a new form template according to the unique identifier of the data structure, setting key fields in the new form template according to the data structure, and recording the form template with the set key fields as the form template matched with the data format.
2. After receiving device target data sent by a mapping file analysis system, storing the device target data into the form template;
and if the equipment access interface information also comprises data state alarm information and the equipment target data stored in the form template accords with the alarm condition, the form system also generates corresponding alarm information.
In this embodiment, a working flow chart of the mapping file analysis system and the form system cooperating to achieve the device target data acquisition and storage is shown in fig. 5, where the working flow chart describes in detail the whole process of the mapping file analysis system acquiring and storing one piece of device target data to the form system according to the device access interface information. Next, the work flow diagram in fig. 5 will be described in text:
step 5-1: when an access cycle entry is reached, the mapping file analysis system judges whether the Internet of things equipment is in an effective state or not (it needs to be stated that the default Internet of things equipment is in the effective state, but the Internet of things equipment may be marked as an invalid state in the process of analyzing equipment target data associated with the mapping file);
if yes, continuing to execute the mapping file analysis; performing step 5-2;
otherwise, the mapping file analysis is interrupted.
Step 5-2: the mapping file analysis system sends the analyzed data format to a form system;
step 5-3: the form system is based on obtaining a form template that matches the data format; in particular, the amount of the solvent to be used,
the form system inquires whether a form template with the same unique data structure identifier is stored in the form system according to the unique data structure identifier,
if the form template is stored, recording the form template as a form template matched with the data format;
if not, a new form template is created according to the unique identifier of the data structure; setting key fields in the new form template according to the data structure, and recording the form template with the set key fields as the form template matched with the data format;
meanwhile, if the equipment access interface information comprises data state alarm information, one or more key fields in the form template are set as alarm fields according to the data state alarm information;
after the complete information of the form template is obtained, recording the form template as a form template corresponding to the Internet of things equipment; feeding back the data format of the equipment to the mapping file analysis system;
step 5-4: after receiving the feedback and finishing the processing of the equipment data format, the mapping file analysis system starts to acquire equipment target data; in particular, the amount of the solvent to be used,
reading the access interface address and linking to an equipment access interface platform;
generating a device interface request using the security authentication information and the device unique identifier; the equipment interface request is used for inquiring equipment data of current Internet of things equipment;
if the equipment interface request is successful, the mapping file analysis system acquires the equipment data from the equipment access interface platform and extracts the equipment target data from the equipment data;
if the equipment interface request is wrong and the equipment is not available or the authority is invalid, marking the current Internet of things equipment as an invalid state, and interrupting the analysis of the mapping file;
otherwise, marking the current Internet of things equipment in an offline state, and taking the obtained latest equipment data of the current Internet of things equipment in the offline state as the equipment target data;
step 5-5: after the acquisition of the equipment target data is completed, the equipment target data is stored in a form template corresponding to the Internet of things equipment;
