Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings 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 of the 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.
Fig. 1 is a block schematic diagram of a communication system based on internet of things devices according to an embodiment of the present invention, as shown in fig. 1, the communication system includes: at least one input internet of things device 1 (1 is taken as an example in fig. 1), a configuration internet of things device 2, and a receiving internet of things device 3 corresponding to the input internet of things device 1, wherein the input internet of things device 1 is used for sending a data sending request, and the data sending request includes data information; the configuration internet of things equipment 2 comprises at least one channel, and the configuration internet of things equipment 2 is used for receiving a data sending request sent by the input internet of things equipment 1 through the channel, filtering, processing and storing data information according to the data sending request, acquiring an information flow strategy according to the data sending request, and sending the data information to the corresponding receiving internet of things equipment 3 through the channel according to the information flow strategy.
In an embodiment of the present invention, the data information may be industrial field data information, and the filtering the data information includes: and filtering invalid information and bad information, and processing the data information, including performing analog-to-digital conversion on the data information.
When the internet of things transmits data information, personal privacy or important information may be involved, and in order to avoid data information leakage caused by hijacking of the data information by a third party, the device 2 for configuring the internet of things is provided with a storage unit, the storage unit and the device 2 for configuring the internet of things are provided with an associated encryption private key and a public key certificate corresponding to the private key, and the public key certificate comprises an information flow strategy.
That is to say, when the internet of things device 2 is configured to transmit data information, the data information is transmitted in an encryption mode, the storage unit and the internet of things device are configured to have a related encryption private key, and a public key certificate corresponding to the private key is created, wherein the public key certificate contains related information flow strategies, and is signed by a user; and when the information flow strategy is received by the equipment for receiving the Internet of things, the private key carries out digital signature. Specifically, when the input internet of things device 1 needs to send data information to the receiving internet of things device 3, the input internet of things device 1 sends a data sending request to the configuration internet of things device 2, where the data sending request includes the data information and information (number, name, bandwidth, etc.) of the receiving internet of things device 3. The internet of things equipment 2 is configured to receive the data sending request, then the data information is filtered, processed and stored according to the data sending request, for example, invalid information and bad information in the data information are filtered, then analog-to-digital conversion is carried out on the filtered data information, then the data information is stored in a memory in a safe mode, then a corresponding information flow strategy is obtained according to the data sending request, and the data information is sent to the corresponding receiving internet of things equipment 3 through a channel according to the information flow strategy. Therefore, the system can transmit the information to the receiving end in a safe mode based on different information flow strategies after filtering, processing and storing the information transmitted by the transmitting end, thereby not only ensuring the safe transmission of the information, but also avoiding the channel delay phenomenon and ensuring the reliability of the information data transmission.
In the present invention, channels are media through which information flows, each channel having a type defined by "channel type", each channel type providing a set of events, including event names and event parameters, which may be external or internal. The channels may be static or dynamic. Static channels are channels that are declaratively specified in a program and automatically created at runtime, while dynamic channels are channels that are explicitly created at runtime according to information flow policies. The handler adapts to the particular channel and handles the events defined by the particular channel.
The channel is further divided into an inner channel and an outer channel. The external channels are similar to sensors that retrieve data from the outside world and other internet of things devices, and the internal channels are used for data processing, each with its own processing program that communicates with each other and the outside world through the channels. The events for each channel are stored in a queue called a pending event queue. The corresponding parameters for each event are stored as a list. Each event may be triggered and mapped to the active channel queue and the next event invoked or invoked accordingly. Runtime may not allow the same event to be run multiple times at a time, thereby regulating the flow of information. When the queue is full, the channel must either block (e.g., when a memory queue is specified) or the operation simply returns without effect (lossy, distributed channel), or it simply pushes out the oldest entry (real-time data flow).
According to one embodiment of the invention, configuring an internet of things device to acquire an information flow strategy according to a data sending request comprises the following steps: acquiring the information type of the data information according to the data sending request; acquiring a bandwidth and a desynchronizing time window according to the information type; and sending the data information to corresponding receiving Internet of things equipment through a channel according to the bandwidth and the desynchronization time window.
In particular, the type of information, i.e., the type of event parameter, the bandwidth can control the amount of information that may flow through the channel, and the desynchronization time window can adjust the time that information flows through the channel. The bandwidths and the desynchronization time windows corresponding to different information types can be prestored in advance, the internet of things equipment 2 is configured to acquire the information type of the data information according to the data sending request, acquire the corresponding bandwidth and the desynchronization time window according to the information type, and send the data information to the corresponding receiving internet of things equipment 3 through the channel according to the bandwidth and the desynchronization time window. Therefore, different information flow strategies are adopted for different data sending requests, the data transmission efficiency can be optimized, and the data transmission effect is ensured.
The current data channel processing technology mainly adopts a polling algorithm, wherein polling refers to that a data processing center sends data receiving requests to data front ends of different channels at a certain time interval, sequentially inquires whether each data front end needs the service, if yes, the data front ends give the service, and inquires the next data front end after the service is finished, and the process is circulated continuously. However, since the data volumes carried by the front ends of different data are different, when the data volume of a certain channel is large, the channel may always occupy the control right, so that the data of other channels cannot be written in real time, and even the data is lost, and therefore, a channel hysteresis phenomenon occurs when a polling algorithm is adopted. In addition, when a polling algorithm is adopted, due to the fact that polling is performed continuously in each data channel, the data processing center needs to repeatedly serve industrial field data with a large amount of repeated data, and operation time is wasted.
Therefore, the invention provides a new channel data processing mode, which comprises the following steps:
according to one embodiment of the invention, the configuring of the internet of things device to process data information according to the data sending request comprises: if the number of the data sending requests is smaller than a preset value and the data volume of the data information carried by the data sending requests is smaller than the preset data volume, configuring the Internet of things equipment to process the data information in a polling mode; if the number of the data sending requests is larger than or equal to a preset value or the data volume of the data information carried by the data sending requests is larger than or equal to the preset data volume, configuring the Internet of things equipment to perform equal-length segmentation on the data information, comparing each segment of information of the data information with the linked list information in the RAM, and if the similarity between the information segment of the data information and the information segment in the linked list information exceeds a preset threshold value, processing the information segment of the data information according to the linked list information; and after the information segments of the data information of which the similarity of the information segments in the linked list information exceeds a preset threshold value are removed, processing the data information in a polling mode. The preset value and the preset data size may be preset according to actual conditions, for example, the preset value may be 20, and the preset data size may be 4 GB.
Specifically, if the current request data sending request is less and the data volume of the data information carried by the data sending request is also less, the internet of things device 2 is configured to process the data information in a polling manner; if the quantity of the data sending requests is large, or the data volume of the data information carried by the data sending requests is large, the Internet of things equipment 2 is configured to equally divide the data information, each piece of information of the data information is compared with the linked list information in the RAM, and common industrial data has large repeatability, so that the linked list information in the RAM can be formed by historical information and updated regularly, if the information fragment of the data information is the same as the information fragment in the linked list information, the linked list information is directly called to process the information fragment, all the same information fragments are stored after being processed, and then the same information fragments as the linked list are removed, and the rest data information fragments are processed in a polling mode. Therefore, by adopting a mode of combining fixed polling and cyclic polling, the data processing capacity can be greatly reduced, particularly for industrial field data information with a large number of repeated information segments, and relevant tests prove that in a data stream saturation transmission mode, the packet loss rate is less than ten thousandth, even no data loss is generated, the channel data transmission has no hysteresis, the channel data feedback time is 0.001S, and the interactive screening of the multichannel queue data can be effectively realized.
It can be understood that the linked list information is stored in the RAM, and the data stream is stored in the data channel memory; the linked list is defined as two kinds of linked lists: a data valid linked list and a data invalid linked list; when a new data stream is written in the memory of the data channel, writing the information and the storage address of the data stream into the effective linked list of the data; when a data packet starting from a certain address in the data channel memory is read, the address information released by the packet is recorded in the data invalid linked list.
In summary, according to the communication system based on the internet of things device in the embodiment of the present invention, the input internet of things device sends a data sending request, the data sending request includes data information, the configured internet of things device includes at least one channel, the configured internet of things device receives the data sending request sent by the input internet of things device through the channel, filters, processes and stores the data information according to the data sending request, obtains the information flow policy according to the data sending request, and sends the data information to the corresponding receiving internet of things device through the channel according to the information flow policy. The system can transmit information to a receiving end in a safe mode based on different information flow strategies after filtering, processing and storing the information transmitted by a transmitting end, thereby not only ensuring the safe transmission of the information, but also avoiding the channel delay phenomenon and ensuring the reliability of the information data transmission.
