As shown in fig. 1, the method of the present embodiment may include the following steps S1100-S1300, which are described in detail below.
Step S1100, receiving a data packet sent by a target device, where the data packet includes status data representing a working status of the target device.
In this embodiment, the target device refers to an internet of things device, which may specifically be an internet of things device in one yard or multiple yards in the rail traffic field, and in different professions and different service systems in multiple train operation lines, for example, the target device may be an internet of things device such as a camera, a gate, a barrier gate, an entrance guard, a lighting device, an air conditioner, a remote control device, and the like, which is not limited in particular herein.
It should be noted that, before implementing the step S1100, that is, before receiving the data packet sent by the target device, the target device needs to be accessed to the internet of things platform first, specifically, the internet of things gateway device described in this embodiment may receive the device access request of the target device, and perform the device access processing on the target device.
That is, in this embodiment, before executing the step of receiving the data packet sent by the target device, the method further includes: receiving a first equipment access request sent by the target equipment; and responding to the first equipment access request, and performing equipment access processing on the target equipment.
In the implementation, the target device and the gateway of the internet of things can be connected through a wireless or wired network, and then the target device is controlled to enter a device access mode so as to send the first device access request to the gateway of the internet of things; after receiving the first device access request, the internet of things gateway device can perform access verification on the device through communication with an internet of things platform, for example, a rail transit internet of things platform.
In this embodiment, the responding to the first device access request performs a device access process on the target device, including: obtaining the equipment type of the target equipment from the equipment access request; according to the equipment type, sending a second equipment access request to the internet of things platform, wherein the internet of things platform is used for determining an object model corresponding to the target equipment and performing access authentication on the target equipment according to the equipment type; and under the condition that the second response message provided by the Internet of things platform represents that the access is successful, sending a first response message representing that the access is successful to the target equipment, wherein the second response message corresponds to the second equipment access request, and the first response message corresponds to the first equipment access request.
The gateway equipment is different from the existing gateway equipment of the internet of things, and needs to perform function upgrading aiming at each type of newly-added equipment, so that the problem of inconvenient use exists. In order to improve the application range of the internet of things gateway, in this embodiment, an object model (TSL, thingSpecificationLanguage) is introduced into an internet of things platform corresponding to the internet of things gateway device, for example, the rail transit internet of things platform in this embodiment, so that when a device is accessed, an association can be established between an actual device and the corresponding object model, and further dynamic configuration and access of the device are realized.
The object model specifically refers to a data model obtained by digitizing the device in the physical space, and specifically can be a JSON file, which can generally describe what the device is, what can do and which information can be provided externally from three dimensions of attributes, services and events. When the object model is used for performing the device access processing, the device can be dynamically configured according to the need, for example, when the device node in the object model corresponding to the target device is determined according to the device type of the target device, the object model can be dynamically expanded according to a communication protocol corresponding to the target device, for example, a Modbus communication protocol, wherein the Modbus communication protocol is a communication protocol which is commonly used by devices in the industrial field, and because the detailed description in the prior art is omitted here.
After the target equipment is accessed to the internet of things platform through the processing, the internet of things gateway equipment can be used for receiving the data message sent by the target equipment to obtain the state data of the target equipment, and the control instruction sent by the internet of things platform and used for controlling the target equipment is received and sent to the target equipment.
In this embodiment, the data packet sent by the target device may be generated by encoding, according to the communication protocol corresponding to the data packet, state data representing the working state of the device; in specific implementation, the status data may be time sequence data generated according to fixed time intervals, early warning data or event data, etc. according to different device types and different device configurations.
Please refer to fig. 2, which is a schematic structural diagram of an internet of things gateway device provided in an embodiment of the present disclosure. As shown in fig. 2, the gateway device of the internet of things according to the embodiment may include a first communication module, where the first communication module may include a first communication sub-module, and the first communication sub-module may be configured to receive a data packet sent by a target device in a manner of serial port communication, socket communication, bacnet, 103/104 protocol, and the like; in addition, the first communication module may further include application middleware (ApplicationMiddleware) that may be configured to receive state data transmitted in JSON format sent by the internet of things device via a protocol such as hypertext transfer protocol (HTTP, hyperTextTransferProtocol).
In the implementation, the internet of things platform can receive the data message sent by the target device through the first communication module, and directly receive the state data in the JSON format sent by the internet of things device, and the specific communication process is not described herein.
After step S1100, step S1200 is performed to parse the data packet through a communication protocol corresponding to the target device, so as to obtain the status data.
Referring to fig. 2 and fig. 3, fig. 3 is a schematic diagram of data processing in an internet of things gateway device according to an embodiment of the disclosure. As shown in fig. 2 and fig. 3, the gateway device of the internet of things may include a data parsing module, where the data parsing module may be a module supporting device communication protocols in various industrial fields, for example, may support communication protocols such as MQTT protocol, opcua protocol, modbus protocol, rola protocol, and the like, and is specifically configured to parse a data packet sent by a target device through a communication protocol corresponding to the target device, that is, decode the data packet, and obtain status data of the target device through further semantic parsing.
Specifically, the parsing the data packet through a communication protocol corresponding to the target device to obtain the status data includes: carrying out message analysis processing on the data message by using a communication protocol corresponding to the target equipment to obtain data to be subjected to semantic analysis; carrying out semantic analysis processing on the data to be subjected to semantic analysis to obtain semantic data corresponding to the target equipment; and generating the state data according to the semantic data.
Namely, after the gateway device of the internet of things receives the data message sent by the target device, the gateway device of the internet of things can firstly perform unshelling treatment through a transmission protocol to obtain an actual message; and then by using a corresponding communication protocol, for example, when the target equipment uses the Modbus protocol to carry out data communication, the gateway equipment of the Internet of things can carry out message analysis processing on the received data message subjected to the transmission protocol unshelling processing by using the Modbus, and carry out semantic translation on the data to be subjected to semantic analysis obtained by analysis to obtain state data representing the working state of the target equipment.
The semantic analysis processing is performed on the data to be semantically analyzed to obtain semantic data corresponding to the target device, and the method specifically comprises the following steps: and acquiring semantic analysis configuration information corresponding to the target equipment, and according to the semantic analysis configuration information, obtaining engineering data parameters, namely physical data parameters, such as voltage and current data of the equipment, of the target equipment by carrying out semantic translation on data in the data to be subjected to semantic analysis.
In the implementation, when the voice analysis configuration information corresponding to the target device is acquired, the device identifier of the target device can be acquired from the data to be semantically analyzed, and then the voice analysis configuration information corresponding to the target device is acquired according to the corresponding relation between the preset device identifier and the semantic analysis configuration information through the device identifier.
After the semantic analysis data of the target device is obtained through analysis, an object model corresponding to the device can be determined according to the device identification of the target device, and object packaging or objectification merging processing can be carried out on the semantic analysis data to obtain the state data.
After step S1200, step S1300 is executed to encrypt the status data, and send the encrypted status data to an internet of things platform, where the internet of things platform is used to monitor the working status of the target device, and the target device accesses the internet of things platform through a corresponding object model.
As shown in fig. 2 and fig. 3, in this embodiment, in order to improve security during data transmission, the gateway device of the internet of things may further include a second communication module, where the second communication module is configured to encrypt, after decoding, the state data of the target device by using a preset encryption algorithm, and send the encrypted state data to the platform of the internet of things, so as to avoid possible risk of data leakage during plaintext transmission.
The encrypting the state data and sending the encrypted state data to an internet of things platform comprises the following steps: and encrypting the state data by using a preset data encryption algorithm, and sending the encrypted state data to the Internet of things platform.
The preset data encryption algorithm may be a symmetric encryption algorithm, an asymmetric encryption algorithm, or the like, and is not particularly limited herein.
It should be noted that, the gateway device of the internet of things may also receive a control instruction for the target device sent by the platform of the internet of things and send the control instruction to the target device, that is, in this embodiment, the method further includes: acquiring a first encrypted control instruction sent by the Internet of things platform, wherein the first control instruction corresponds to the target equipment; decrypting the encrypted first control instruction by using a preset data encryption algorithm to obtain the first control instruction; and sending the first control instruction to the target equipment.
Wherein the sending the first control instruction to the target device includes: encoding the first control instruction by using a communication protocol corresponding to the target equipment to obtain an instruction issuing data message corresponding to the first control instruction; and sending the instruction sending data message to the target equipment.
That is, the control command may be encoded by driving the reverse encoding/interface as shown in fig. 2, and sending the command-issued data message to the target device.
As shown in fig. 3, in the implementation, the second communication module of the gateway device of the internet of things performs data interaction with the platform of the internet of things, that is, sends device state data to the platform of the internet of things, or receives a control instruction sent by the platform of the internet of things, and then performs data interaction with the platform of the internet of things in a manner of transmitting the encrypted JSON string through the industrial control real-time interface shown in fig. 3 by installing data synchronization application software in the gateway device of the internet of things.
It should be noted that in practice, the gateway device of the internet of things and the platform of the internet of things are often in a tight coupling relationship, that is, when the platform of the internet of things stops serving, the device state data collected by the gateway device of the internet of things cannot be normally sent to the platform of the internet of things, so that the problem that the data is interrupted in time sequence may be caused; during the period, the internet of things platform stops serving, and a user cannot remotely issue a control instruction to control the target device through the internet of things platform, so that the problem of inconvenient use and influence on user experience may exist.
For this problem, as shown in fig. 2, in the implementation, the internet of things gateway device and the internet of things platform may be decoupled, that is, an edge computing module may be integrated in the internet of things gateway device according to this embodiment, where the edge computing module may provide a device data storage and a simple control instruction issuing function during a period when the internet of things platform stops serving.
That is, in this embodiment, before executing the step of encrypting the state data and sending the encrypted state data to the platform of the internet of things, the method further includes: acquiring a network connection state with the Internet of things platform; storing the state data in case the network connection state characterizes a network connection disconnection; and receiving a second control instruction aiming at the target equipment, and sending the second control instruction to the target equipment.
In this embodiment, in case the network connection status characterizes that a network connection is connected, the method further comprises: when the Internet of things gateway equipment stores historical state data corresponding to the target equipment, the historical state data is sent to the Internet of things platform; and, emptying the historical state data.
That is, the edge computing module can be used as an edge computing node of the internet of things platform, and has the capabilities of field data processing and simple service processing as a part of the internet of things platform, and provides a field self-sustaining function when the internet of things platform fails, so that a user can continuously monitor and control target equipment. And after the fault of the internet of things platform is relieved and service is restored, in order to ensure that monitoring data in the internet of things platform is continuous in time sequence, an edge calculation module in the gateway equipment of the internet of things can send historical state data of the target equipment stored during the fault of the platform to the internet of things platform, and after the sending is completed, the historical state data is emptied.
It should be noted that, the above is an embodiment for implementing the edge computing function provided by the gateway of the internet of things according to the embodiments of the present disclosure, and in a specific implementation, other functions may be integrated in the edge computing module of the gateway of the internet of things, so as to provide better services for users, which is not described herein.
As can be seen from the foregoing, in the data processing method provided in this embodiment, by integrating the first communication module, the data analysis module, the edge calculation module, the second communication module and other modules in the gateway device of the internet of things, after the gateway device of the internet of things receives the data packet sent by the target device, the communication protocol corresponding to the target device can be used to analyze the data packet, so as to obtain the state data of the target device; meanwhile, in order to ensure the safety during data transmission and avoid the risk of data leakage, the gateway equipment can encrypt the state data when sending the state data to the target equipment and send the encrypted state data to the internet of things platform. According to the method, the gateway equipment of the Internet of things can conveniently collect state data of various equipment and improve safety in data transmission, and when the platform of the Internet of things breaks down, station-level self-holding capacity can be achieved through the edge computing module, so that user experience is improved.
