For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The wireless technology enables the equipment to establish network connection between terminal equipment of the transformer substation and realize communication between the terminal equipment under the condition that a cable is not needed, the cable is not needed to be laid in the transformer substation, the work such as trench construction is avoided, and the layout and construction cost is effectively reduced.
However, in the transformer substation, part of sites have the defects that the signals of operators cannot cover or signals are unstable, meanwhile, the channel utilization rate is low, the communication cost is high, the electromagnetic interference in the received station is serious and the like, and the monitoring requirement of the data of the transformer substation is difficult to meet.
Based on the above, the fusion communication system and the monitoring method provided by the embodiment of the invention can effectively alleviate the technical problems.
For the sake of understanding the present embodiment, a detailed description will be given of a converged communication system disclosed in the present embodiment.
In a possible implementation manner, the embodiment of the present invention provides a converged communication system, which is shown in fig. 1 and includes a terminal 10, a sink node 20, an access node 30 and a monitoring platform 40 that are sequentially connected.
In fig. 1, the terminals in the embodiment of the present invention include a first terminal 101 that accesses a sink node in a wireless narrowband communication manner and a second terminal 102 that accesses the sink node in a wireless broadband communication manner; in consideration of the fact that more data needs to be monitored in the transformer substation, the number of the first terminals and the second terminals in the embodiment of the present invention may be multiple, and the number of the sink nodes and the access nodes may also be multiple, where, for convenience of explanation, in fig. 1, two first terminals and two second terminals, and an embodiment of one sink node and one access node are shown respectively, in actual use, the number of the first terminals and the second terminals may be set according to actual use conditions, and each access node may also correspond to multiple sink nodes, or multiple access nodes are connected to a monitoring platform, and so on, specifically, in terms of actual use conditions, the embodiment of the present invention is not limited to this.
Further, the terminal is configured to monitor operation data of the substation after accessing the converged communication system, and send the monitored operation data to the access node via the sink node; the access node is used for carrying out security detection on the accessed terminal, allowing the terminal to access after the security detection passes, receiving operation data sent by the accessed terminal, carrying out state analysis on the operation data, and reporting an analysis result to the monitoring platform.
When in actual use, according to the application condition of the transformer substation site, various data with different data sizes, different time intervals and different data importance degrees need to be considered when the terminal is arranged, the monitoring and reporting requirements of the data are different, and meanwhile, the data communication anti-interference is a problem that the terminal is arranged in the transformer substation and needs to be considered mainly. Therefore, in the embodiment of the invention, the first terminal which is connected with the sink node in a wireless narrowband communication mode and the second terminal which is connected with the sink node in a wireless broadband communication mode are adopted to meet the requirements of monitoring and communication of data in the transformer substation. The embodiment of the invention is actually a wide-narrow band fusion communication system, and the scheme of the wide-narrow band fusion not only meets the reliability requirement of monitoring data transmission in a complex electromagnetic environment, but also meets the requirement of high-speed and real-time transmission of the monitoring data.
Therefore, the converged communication system provided by the embodiment of the invention can be used for accessing the first terminal accessed in a narrowband communication mode and the second terminal accessed in a broadband communication mode in the converged communication system, monitoring the operation data of the transformer substation after the terminal is accessed in the converged communication system, sending the monitored operation data to the access node through the aggregation node, and the access node is used for carrying out safety detection on the accessed terminal, allowing the terminal to be accessed after the safety detection is passed, receiving the operation data sent by the accessed terminal, carrying out state analysis on the operation data, and reporting an analysis result to the monitoring platform, so that the operation data of the transformer substation is monitored.
In an actual use, in the embodiment of the present invention, the first terminal is configured to perform data interaction according to a preset period; the second terminal is configured to report the operation data in real time.
Specifically, the terminal with the requirements of large data volume and high real-time performance is accessed by adopting a wireless broadband communication mode, namely, the second terminal in the embodiment of the invention is used for monitoring and reporting the operation data with the requirements of large data volume and high real-time performance, namely, the second terminal can report the operation data in time under any condition, such as the operation data of an online monitoring local discharge sensor, a switch relay, an access controller and the like.
The operation data reported at a fixed interval with low power consumption is generally transmitted in a wireless narrowband communication mode, that is, the first terminal in the embodiment of the invention is used, so that the first terminal can be configured to perform data interaction according to a preset period, that is, perform data interaction after periodically performing dormancy and awakening, so as to meet the requirement of low power consumption, for example: and monitoring and reporting data of a temperature and humidity sensor, a water immersion water level sensor, an SF6 micro water density sensor and the like.
Further, in order to achieve the access of the first terminal and the second terminal, the sink node in the embodiment of the present invention includes a narrowband access unit and a broadband access unit; the narrowband access unit is used for accessing the first terminal, and the broadband access unit is used for accessing the second terminal.
In a specific implementation, in the embodiment of the present invention, the above wireless narrowband communication mode is a narrowband LORA communication mode, and the wireless broadband communication mode is a broadband WAPI (WIRELESS LAN Authentication AND PRIVACY information) communication mode; further, the sink node adopts a wired Ethernet to perform network interaction with the access node; the access node adopts a wired Ethernet to perform network access interaction with the monitoring platform.
The LORA communication mode belongs to one of wireless communication technologies, and adopts a CSS (CHIRP SPREAD Spectrum modulation) spread spectrum modulation technology, so that the receiving sensitivity can be improved to the maximum efficiency, and meanwhile, the LORA communication mode has the characteristics of long communication distance, low power consumption, strong anti-interference capability and the like. The WAPI communication mode can transmit the data in a key mode, so that the safety of the converged communication system is improved.
Therefore, the first terminal and the second terminal can respectively adopt a narrow-band LORA communication mode and a broadband WAPI communication mode to transmit the operation data obtained by monitoring to the sink node.
The sink node is usually realized by one or more sink devices, generally has functions of network communication relay, data and instruction forwarding, subordinate device management scheduling and the like, and adopts a wired Ethernet to carry out network access interaction, control instruction issuing, monitoring data reporting and the like with the access node.
The access node has functions of building management, equipment scheduling, data receiving and the like of the whole wireless network in the converged communication system, and can process and calculate the operation data reported by the terminal and the sink node, for example, the reported operation data is subjected to state analysis according to a pre-configured mathematical model so as to monitor whether the operation state representation is met or not, and the like, and the result is reported to the monitoring platform according to the communication specification requirement.
In addition, the access node can also complete the management and the scheduling of the broadband convergence network, receive the control instruction of the monitoring platform to configure each terminal, and complete the network communication frequency point allocation, the scheduling of the communication time slots of the same-layer terminals or devices, the terminal data reporting period configuration, the wireless transmitting power configuration and the like.
Based on the above functions, the access node in the embodiment of the present invention is also responsible for performing security detection on the accessed terminal, where the security detection process performed on the accessed terminal is usually performed when the terminal accesses the converged communication system for the first time, and includes access detection of the first terminal and access detection of the second terminal.
Specifically, the process of access detection for the first terminal includes the following:
(1) Responding to an access request of a first terminal forwarded by an aggregation node, and extracting an identity of the first terminal carried in the access request of the first terminal;
(2) Detecting whether the identity of the first terminal is in a preconfigured allowed access list or not;
(3) If so, sending a response message allowing access to the sink node, and forwarding the response message to the first terminal through the sink node so as to allow the first terminal to access.
Specifically, based on the above detection process, when the first terminal accesses for the first time, the first terminal may send an access request to the sink node, and the sink node forwards the access request to the access node for processing. Meanwhile, the access node is preconfigured with an allowed access list to record the identity of the first terminal allowed to access the converged communication system, such as an EID electronic identity, and the like, and generally, when the first terminal is arranged, the identity of the first terminal can be directly added into the allowed access list, so that when the first terminal is accessed for the first time, access detection can be performed on the first terminal, and the overall safety is improved.
In addition, besides the allowed access list, the access node is further configured with a forbidden access list, that is, the forbidden access list records the identity of the terminal forbidden to access the converged communication system. In practical use, the allowed access list is equivalent to a white list, the forbidden access list is equivalent to a black list, and the access node can detect the accessed terminal according to the white list and the black list.
If the access node detects that the identity of the first terminal is not in a pre-configured allowed access list, judging whether the identity of the first terminal is in a pre-configured forbidden access list or not; if yes, sending a forbidden access message to the first terminal through the sink node; if not, the identity of the first terminal is sent to the rechecking terminal.
The rechecking terminal can be a terminal used by operation and maintenance personnel, and the access terminal can be rechecked manually. Specifically, if the access node receives the access permission message returned by the rechecking terminal, the access node sends a response message for permitting access to the first terminal through the sink node, and adds the identity of the first terminal to an access permission list; and if the access prohibition message returned by the rechecking terminal is received, the access prohibition message is sent to the first terminal through the sink node, and the identity of the first terminal is added to the access prohibition list.
Therefore, the access node can judge whether the terminal accessing the converged communication system through different modulation modes is permitted to join the network of the converged communication system according to the setting of the white list and the black list and the manual rechecking mode. In general, after the sink node joins the network of the converged communication system, the access node may also issue the configuration information of its downlink working channel to the sink node, that is, the access node may complete the process of setting up, scheduling and configuring the network of the whole converged communication system by controlling the configuration of the accessed terminal and the downlink working frequency point, the configuration of the data reporting period, and the like.
For easy understanding, fig. 2 shows a flow chart of narrowband communication access, and shows main flows of an access node, a sink node and a terminal in the narrowband communication access process. As shown in fig. 2, the method comprises the following steps:
(1) And (3) power-on process: the equipment corresponding to the access node and the sink node and the terminal are electrified;
(2) The sink node obtains the time slot time allocated by the upper node according to the broadcast frame content of the upper node (such as an access node), and initiates a random access request in an idle time slot of the upper node, and the sink node joins the access node network;
In this process, the access node may interact with the sink node, such as the random access response, random join response, etc. process shown in fig. 2.
(3) After the sink node joins the network of the converged communication system, the access node issues a node channel working configuration to the sink node, so that the sink node can respond to the network layer response after the configuration is successful.
In this process, if the access node has other configuration data to be issued, for example, the synchronous acquisition configuration of the first terminal or the second terminal, etc., the network layer may be continuously used for issuing until the configuration is completed.
(4) The access node performs network access interaction with the terminal;
in this process, the access node may respond to the access request of the first terminal according to the preconfigured allowed access list and the forbidden access name, for example, the access node sends a response message for allowing access to the sink node, so that the sink node forwards the response message to the first terminal, or the access node sends a forbidden access message to the sink node, and sends a response for prohibiting access message to the first terminal via the sink node, and so on.
Further, for the first terminal that is allowed to access, the first terminal may also be added to the network topology of the converged communication system.
(5) The access node issues a configuration instruction to the first terminal according to the requirement;
In this process, for the first terminal allowed to access, the access node may perform configuration, such as configuring a communication parameter of a sensor, etc., specifically, may issue a configuration instruction to the sink node, and then the sink node converts the configuration instruction into a configuration execution of a terminal layer, such as converting into a configuration instruction of a MAC layer, and after forwarding to the first terminal, the first terminal may receive the configuration instruction and perform configuration.
(6) The first terminal reports the monitored operation data.
After the first terminal is added into the converged communication system, actions such as data reporting, dormancy awakening, network topology change and the like are completed by receiving instructions such as scheduling, configuration and the like issued by the access node, so that the functional requirements of low power consumption, data monitoring and periodic reporting of operation data are met.
Further, in the embodiment of the present invention, the process of access detection for the second terminal includes the following contents:
Responding to an access request of a second terminal forwarded by the sink node, and acquiring authentication key information matched with the second terminal in advance; authenticating the second terminal by adopting authentication key information; if the authentication is passed, sending a message allowing access to the second terminal through the sink node; and if the authentication does not pass, sending a message for prohibiting access to the second terminal through the sink node.
Specifically, the access procedure of the second terminal is actually an access procedure of a broadband WAPI communication mode, and in order to realize the access of the second terminal, in the embodiment of the present invention, the network topology of the converged communication system includes the following three entities:
(1) The authentication requester entity ASUE (Authentication SUpplicant Entity), before accessing the service, in this embodiment of the present invention, is an entity that requests an authentication operation before accessing the converged communication system, and in this embodiment of the present invention, the entity resides in the second terminal.
(2) The authenticator entity AE (Authenticator Entity) is an entity that provides authentication operations for authenticating a requester entity (e.g., a second terminal in an embodiment of the present invention) prior to accessing a service. The entity typically resides in the device of the sink node or the device of the access node in embodiments of the invention.
(3) The authentication service unit ASU (Authentication Service Unit), whose basic functions are to manage the user certificate and authenticate the user identity by pre-sharing the secret key and license certificate, is an important component in the WAI (WLANAuthentication Infrastructure) authentication infrastructure based on public key cryptography. The certificate managed by the ASU includes the public key and signature of the certificate issuer (ASU) and the public key and signature of the certificate holder STA (Station) and AP (Access Point), and uses the elliptic curve specific to WAPI as the digital signature algorithm. The entity typically resides in the device of the access node of an embodiment of the invention.
Based on the above entity, in the embodiment of the present invention, the process of access detection for the second terminal is actually a process of authentication and key management for WAPI, and the process of access detection for the second terminal generally includes two authentication modes, namely, two modes based on certificates and on pre-shared keys, and if adopting the authentication mode based on certificates, the whole process includes certificate authentication, unicast key negotiation and multicast key notification; if the authentication mode of the pre-shared key is adopted, the whole process is unicast key negotiation and multicast key notification.
Further, for easy understanding, fig. 3 shows a flow chart of access in a wide communication manner, and a procedure of access detection of the second terminal is described, as shown in fig. 3, including a procedure of certificate authentication, unicast key negotiation, and multicast key notification.
As shown in fig. 3, the interaction process of certificate authentication includes:
(1) Authenticating the activation packet;
(2) Access authentication request packets;
(3) Certificate authentication request packets;
(4) Certificate authentication response packets;
(5) Access authentication response packets.
Further, the interaction process of unicast key negotiation includes:
(1) Unicast key negotiation request packets;
(2) Unicast key negotiation response packets;
(3) Unicast key negotiation acknowledgement packets.
Further, the interaction process of the multicast key notification includes:
(1) Multicast key advertisement packets;
