The execution body may include a gateway side 102 and a configuration server side 104, where the gateway side 102 and the configuration server side 104 are communicatively coupled. Specifically, the gateway 102 responds to the access request of the target device 106, and identifies the device information of the target device 106; based on the device information, a configuration file issuing request is sent to the configuration server 104, the configuration server 104 analyzes the configuration file issuing request to obtain device information of the target device 106, then queries a preset mapping relation table to obtain a point table configuration file corresponding to the device information, and issues the point table configuration file to the gateway 102, and the gateway 102 completes the point table automatic configuration process of the target device 106 according to the received point table configuration file.

step S202, in response to an access request of a target device, identifying device information of the target device.

The target device refers to a device to be accessed to the gateway end, such as a temperature sensor, a humidity sensor, a distance sensor and the like. The access request refers to a signal sent by the target device to the gateway end for requesting access. The device information refers to attribute information of the target device, and may include, but is not limited to, a device name, a device type, a manufacturer, a device model, a device serial number, etc., where the device information is used to configure the server side to query a point table configuration file of the target device.

Specifically, when receiving an access request of the target device, the gateway end may send a detection message to the target device to extract a target feature of the target device, so as to perform feature matching on the target device based on the target feature, and further determine device information of the target device according to a finally obtained feature matching result. The detection message is a special message segment and is used for extracting the target characteristics of target equipment.

Step S204, based on the equipment information, a configuration file issuing request is sent to a configuration server side.

The configuration file issuing request is used for indicating the configuration server to inquire and return the point table configuration file corresponding to the equipment information.

Specifically, after identifying the device information of the target device, the gateway end generates a request signal carrying the device information, namely a configuration file issuing request, and sends the configuration file issuing request to the configuration server end, so that the configuration server end queries the point table configuration file corresponding to the device information, and returns the point table configuration file to the gateway end.

Step S206, receiving the point table configuration file to realize automatic configuration of the point table of the target equipment.

Wherein the point table is used for representing the use condition of each variable in the equipment. The point list is used as an important basis and protocol standard of equipment providers, software providers and system integrators, and the construction of the whole automatic control system is based on the description and the regulation of variables in the point list. Typically, each variable will have a corresponding unique variable name, device address, register address, etc. point table parameter. For each terminal device, the device manufacturer can provide the point table parameters of each device, and for the devices of the same manufacturer, the same type and model, the point table parameters of the corresponding device can be obtained once the device information of the device manufacturer, the type, the model and the like is obtained. And the point table configuration file records the point table parameters corresponding to the target equipment.

Specifically, the gateway receives the point table configuration file of the target device returned by the configuration server, and automatic configuration of the point table of the target device is realized. The gateway terminal can read the configuration file information of the point table, so that the gateway terminal can acquire data of the target equipment according to the configuration file information of the point table in the system.

In this embodiment, the gateway terminal first responds to the access request of the target device, and automatically identifies the device information of the target device, so that, based on the device information, a configuration file issuing request is sent to the configuration server terminal to instruct the configuration server terminal to query and return the point table configuration file corresponding to the device information, and finally, the point table configuration file is received, thereby realizing automatic configuration of the point table of the target device, no manual operation is required in the whole process, and automation of point table configuration during device access is realized. Compared with the prior manual configuration method of the point table information of the terminal equipment, the method has the advantages that the manual participation degree and the workload are greatly reduced, the configuration efficiency of the equipment point table is improved, the problem of easy error in manual configuration is avoided, and the configuration accuracy of the equipment point table is improved.

In one embodiment, as shown in fig. 3, the identifying, in response to an access request of a target device, device information of the target device includes:

step S302, in response to the access request of the target device, extracting the target feature of the target device.

The target features refer to device features of the target device, and may include static features and dynamic features, where the static features refer to features extracted from message information of the target device, and the dynamic features refer to features extracted from flow information of the target device.

Specifically, when receiving an access request of the target device, the gateway end obtains static characteristics and dynamic characteristics of the target device by sending a detection message to the target device.

In an embodiment, the gateway end obtains the message information of the target device by sending a detection message to the target device, where the message information may include a message structure, and the gateway end may determine a communication protocol type of the target device according to the message structure of the target device, and use the communication protocol type as a static feature of the target device.

In an embodiment, the gateway side obtains the traffic information of the target device by sending a detection message to the target device, where the traffic information may include ingress and egress packet information, source IP (Internet Protocol ) address traffic information, destination IP address traffic information, and the like, and the gateway side may obtain, according to the ingress and egress packet information, the number of outgoing packets of the target device, the rate of outgoing packets of the device, the number of ingress packets of the device, the rate of ingress packets of the device, the number of erroneous packets of the device, the link delay, the link packet loss rate, and uses the source IP address traffic information, the destination IP address traffic information, the number of outgoing packets of the device, the number of ingress packets of the device, the rate of ingress packets of the device, the number of erroneous packets of the device, the link delay, and the link packet loss rate of the link as dynamic characteristics of the target device.

Step S304, matching the target features with a pre-established device feature library to obtain feature matching results.

Step S306, determining device information corresponding to the target feature based on the feature matching result.

The corresponding relation between each pre-stored feature and each pre-stored device information is stored in the device feature library. The pre-stored device refers to all types of devices in the access gateway which are required in advance, the pre-stored feature refers to the device feature corresponding to the pre-stored device, the pre-stored device information refers to the device information corresponding to the pre-stored device, and it can be understood that the pre-stored feature has the same meaning as the target feature, and the pre-stored feature also includes a pre-stored static feature and a pre-stored dynamic feature, and the explanation about the target feature, the static feature and the dynamic feature can be referred to specifically.

The feature matching result is used for representing whether the target feature is consistent with the pre-stored feature, and the feature matching process comprises static feature matching and dynamic feature matching, so that the feature matching result can also comprise the static feature matching result and the dynamic feature matching result.

In an embodiment, before the automatic configuration of the device point table is performed, the gateway side may perform feature extraction on all types of pre-stored devices that need to be accessed into the gateway in advance, and store the extracted pre-stored features, pre-stored device information of the pre-stored devices, and correspondence between the pre-stored features and the pre-stored device information, so as to form a device feature library, so that when the device point table is configured, the gateway side may quickly obtain the device information of the target device by querying the device feature library, thereby improving the efficiency of the device point table configuration.

Specifically, the gateway end performs one-to-one matching on the target features of the target device and pre-stored features stored in a pre-established device feature library, namely, the static features of the target device are matched with the pre-stored static features to obtain a static feature matching result, the dynamic features of the target device are matched with the pre-stored dynamic features to obtain a dynamic feature matching result, and when the two matching results are consistent, the device information corresponding to the pre-stored static features and the pre-stored dynamic features is obtained according to the corresponding relation between the pre-stored features and the device information, and the device information is the device information of the target device.

In the embodiment, the dynamic characteristics and the static characteristics of the target equipment are extracted, and the dynamic characteristics and the static characteristics are matched with the pre-stored characteristics in the equipment characteristic library, so that the equipment information of the target equipment is rapidly determined, the determining efficiency of the equipment information is improved, and the efficiency of equipment point table configuration is improved.

In one embodiment, as shown in fig. 4, the sending, based on the device information, a configuration file issuing request to a configuration server side includes:

step S402, encrypting the equipment information by using a preset encryption key to obtain equipment information ciphertext corresponding to the equipment information.

The gateway end and the configuration server end establish communication connection through a preset network security protocol, and the preset network security protocol can realize safe access, file transmission and other services through an encryption and authentication mechanism. When the gateway end and the configuration server end establish communication, the two parties negotiate a key exchange algorithm finally used for generating a preset encryption key, an encryption algorithm used for encrypting data information, a public key algorithm used for digital signature and authentication and an HMAC (Hash message authentication codes, hash operation message authentication code) algorithm used for protecting data integrity according to encryption algorithms respectively supported by the two parties.

The gateway terminal and the configuration server terminal dynamically generate a shared preset encryption key sum through a key exchange algorithm, and establish an encryption channel. The preset encryption key is used for encrypting and decrypting the subsequent data transmission, namely encrypting the equipment information and decrypting the equipment information ciphertext. In this embodiment, the preset encryption key may be a symmetric key, that is, the gateway end and the configuration server end may only use the encryption key to encrypt and decrypt, and compared with asymmetric encryption, the encryption and decryption speed of the symmetric encryption algorithm is faster.

Specifically, after the gateway side identifies the device information of the target device, the device information is encrypted by using a preset encryption key, and the device information is converted into a ciphertext form from a plaintext form, so as to obtain a device information ciphertext corresponding to the device information, wherein the device information ciphertext is ciphertext information obtained after the device information is encrypted.

Step S404, a configuration file issuing request carrying the equipment information ciphertext is sent to the configuration server side.

Specifically, after the gateway end completes the encryption processing of the device information, a configuration file issuing request is generated, and the encrypted device information ciphertext is written into the configuration file issuing request and is sent to the configuration server end, so that the configuration server end can directly decrypt the device information from the configuration file issuing request, and the corresponding point table configuration file is queried.

In this embodiment, the security of the device information in the transmission process is ensured by performing encryption processing on the device information of the target device, that is, the security of the whole device point table configuration process is ensured, and the encryption speed can be improved by performing symmetric encryption by using the preset encryption key, so that the transmission rate of the device information is improved, and the efficiency of device point table configuration is further improved.

In one embodiment, as shown in fig. 5, there is further provided a device point table configuration method, which is illustrated by using the configuration server 104 in fig. 1 as an example, and includes the following steps:

step S502, receiving a configuration file issuing request sent by a gateway end, and analyzing the configuration file issuing request to obtain device information of target devices.

The configuration file issuing request is sent to the configuration server side by the gateway side, and is used for indicating the configuration server side to query and return a point table configuration file corresponding to equipment information, where the equipment information refers to attribute information of target equipment, and the attribute information may include, but is not limited to, equipment name, equipment type, manufacturer, equipment model, equipment serial number, etc., and the target equipment refers to equipment to be accessed to the gateway side, such as a temperature sensor, a humidity sensor, a distance sensor, etc.

Specifically, when the configuration server receives a configuration file issuing request sent by the gateway, the configuration file issuing request is analyzed and decrypted to obtain the device information of the target device. The device information of the target device is determined according to a finally obtained feature matching result by performing feature matching on the target device based on the target feature by sending a detection message to the target device when the gateway side receives an access request of the target device so as to extract the target feature of the target device. The target features refer to device features of the target device, and may include static features and dynamic features, where the static features refer to features extracted from message information of the target device, and the dynamic features refer to features extracted from flow information of the target device.

In an embodiment, the gateway end matches the target feature with a pre-established device feature library to obtain a feature matching result, and determines device information corresponding to the target feature based on the feature matching result. The corresponding relation between each pre-stored feature and each pre-stored device information is stored in the device feature library. The pre-stored device refers to all types of devices in the access gateway which are required in advance, the pre-stored feature refers to the device feature corresponding to the pre-stored device, the pre-stored device information refers to the device information corresponding to the pre-stored device, and it can be understood that the pre-stored feature has the same meaning as the target feature, and the pre-stored feature also includes a pre-stored static feature and a pre-stored dynamic feature, and the explanation about the target feature, the static feature and the dynamic feature can be referred to specifically. The feature matching result is used for representing whether the target feature is consistent with the pre-stored feature, and the feature matching process comprises static feature matching and dynamic feature matching, so that the feature matching result can also comprise the static feature matching result and the dynamic feature matching result.

Step S504, inquiring a preset mapping relation table to obtain a point table configuration file corresponding to the equipment information.

The preset mapping relation table records the corresponding relation between the information of each pre-stored device and the configuration file of each pre-stored point table. The pre-stored point table configuration file refers to a point table configuration file corresponding to pre-stored equipment.

Specifically, after obtaining the device information of the target device, the configuration server side queries the pre-stored device information corresponding to the device information in a preset mapping relation table, and queries the point table configuration file corresponding to the pre-stored device information corresponding to the device information in each pre-stored point table configuration file according to the corresponding relation between each pre-stored device information and each pre-stored point table configuration file.

Step S506, the point table configuration file is issued to the gateway side.

The point table configuration file is used for collecting data of the target equipment in the gateway side in the system. The point table is used to characterize the usage of the various variables in the device. The point list is used as an important basis and protocol standard of equipment providers, software providers and system integrators, and the construction of the whole automatic control system is based on the description and the regulation of variables in the point list. Typically, each variable will have a corresponding unique variable name, device address, register address, etc. point table parameter. For each terminal device, the device manufacturer can provide the point table parameters of each device, and for the devices of the same manufacturer, the same type and model, the point table parameters of the corresponding device can be obtained once the device information of the device manufacturer, the type, the model and the like is obtained. And the point table configuration file records the point table parameters corresponding to the target equipment.

Specifically, the configuration server side sends the queried point table configuration file to the gateway side, so that automatic configuration of the point table of the target equipment is realized. The gateway terminal can read the configuration file information of the point table, so that the gateway terminal can acquire data of the target equipment according to the configuration file information of the point table in the system.

In this embodiment, the configuration server side first receives a configuration file issuing request sent by the gateway side, analyzes the configuration file issuing request to obtain device information of the target device, then queries a preset mapping relation table to obtain a point table configuration file corresponding to the device information, and issues the point table configuration file to the gateway side, thereby implementing automatic configuration of the point table of the target device, so that the gateway side in the system can perform data acquisition on the target device according to the point table configuration file, no manual operation is required in the whole process, and automation of point table configuration when the multi-service scene gateway of the power system accesses the accessed terminal device is implemented. Compared with the prior manual configuration method of the point table information of the terminal equipment, the method has the advantages that the manual participation degree and the workload are greatly reduced, the configuration efficiency of the equipment point table is improved, the problem of easy error in manual configuration is avoided, and the configuration accuracy of the equipment point table is improved.

In one embodiment, as shown in fig. 6, the parsing the configuration file issuing request to obtain device information of the target device includes:

step S602, analyzing the configuration file issuing request to obtain a device information ciphertext corresponding to the configuration file issuing request.

Step S604, the device information ciphertext is decrypted by using a preset encryption key to obtain the device information of the target device.

The gateway end and the configuration server end establish communication connection through a preset network security protocol, and the preset network security protocol can realize safe access, file transmission and other services through an encryption and authentication mechanism. When the gateway end and the configuration server end establish communication, the two parties negotiate a key exchange algorithm finally used for generating a preset encryption key, an encryption algorithm used for encrypting data information, a public key algorithm used for digital signature and authentication and an HMAC algorithm used for protecting data integrity according to encryption algorithms supported by the two parties.

Specifically, after resolving the equipment information ciphertext of the target equipment from the configuration file issuing request, the configuration server end decrypts the equipment information ciphertext by using a preset encryption key, and converts the equipment information ciphertext from a ciphertext form to a plaintext form, so as to obtain equipment information corresponding to the equipment information ciphertext, wherein the equipment information ciphertext is ciphertext information obtained after the equipment information is encrypted.

In this embodiment, the encryption and decryption processing is performed on the device information of the target device, so that the security of the device information in the transmission process is ensured, that is, the security of the whole device point table configuration process is ensured, and the symmetric encryption is performed by using the preset encryption key, so that the encryption and decryption speed can be improved, the transmission rate of the device information is improved, and the efficiency of the device point table configuration is improved.

In an embodiment, the target device may be a temperature and humidity sensor with a model number of HTS40L, the gateway end is an SSH (Secure Shell) client, and the configuration server end is an SSH server end. Specifically, as shown in fig. 7, when receiving an access request of an HTS40L temperature and humidity sensor, an SSH client sends a detection message to the HTS40L temperature and humidity sensor to extract equipment characteristics of the HTS40L temperature and humidity sensor, matches the equipment characteristics with an equipment characteristic library, outputs equipment information corresponding to the HTS40L temperature and humidity sensor, generates a configuration file according to the equipment information, sends the request to an SSH server, and inquires a point table configuration file corresponding to the equipment information and sends the point table configuration file to the SSH client, thereby realizing automatic configuration of the HTS40L temperature and humidity sensor point table, and a gateway in a system performs data acquisition on the HTS40L temperature and humidity sensor according to the point table configuration file.

The process of establishing the device feature library can refer to the device feature library establishment flow in fig. 7, and the gateway can pre-extract dynamic device features and static device features of different types of terminal devices to be used as device features together, and combine device information of each terminal device, so as to establish the device feature library.

And manually configuring point table parameters in the gateway once according to equipment point table information provided by a manufacturer for all types of terminals needing to be accessed to the edge gateway in the electric power Internet of things, generating different configuration files corresponding to different types of terminals, establishing communication between the gateway and the configuration server through a network security protocol, and uploading the point table configuration files, the equipment information and the mapping of the point table configuration files and the equipment information of different types of terminal equipment to the configuration server. The configuration server can form a preset mapping relation table by the point table configuration files of different types of terminal equipment and the corresponding relation between the point table configuration files and the equipment information of each terminal equipment and store the mapping relation table. Referring to fig. 8, after different types of terminal devices access the gateway, the gateway identifies the device information of each terminal device, and then configures the device information manually in the gateway according to the point table information provided by the manufacturer to generate a point table configuration file, and finally the device information of all terminal devices, the point table configuration file of all terminal devices and the corresponding relationship between them can be uploaded to a configuration server for storage.

The configuration process of the point table of the device in multiple scenes can refer to fig. 9, and the point table configuration process of different terminals in each scene is the same, namely, the gateway terminal firstly identifies the device information, and then sends a configuration file issuing request to the configuration server, so that the point table configuration file of each terminal device is obtained, and the automatic configuration of the point table of each terminal device is completed.

In this embodiment, the gateway responds to the access request of the HTS40L temperature and humidity sensor to automatically identify the equipment information of the HTS40L temperature and humidity sensor, so that, based on the equipment information, the gateway sends a configuration file issuing request to the SSH server as the SSH client to instruct the SSH server to query and return the point table configuration file corresponding to the equipment information, and finally, the gateway receives the point table configuration file to complete the automatic configuration of the point table of the HTS40L temperature and humidity sensor, and the whole process does not need manual operation, thereby realizing the automation of the point table configuration when the HTS40L temperature and humidity sensor is accessed. Compared with the prior manual configuration method of the point table information of the terminal equipment, the method not only greatly reduces the manual participation and workload, improves the configuration efficiency of the HTS40L temperature and humidity sensor point table, but also avoids the problem of easy error in manual configuration, and improves the configuration accuracy of the HTS40L temperature and humidity sensor point table.
