Problems solved by technology

[0003] The rapid increase in the number of devices has brought obvious problems to the installation of circuit breakers: if the traditional method of manually connecting devices to the network is used, firstly, because of the large number of devices, the management of circuit breakers will be a responsible issue. Even if a dangerous situation is discovered, technicians may still not know the occurrence of the dangerous situation, or may not be able to perform correct operations in time
Second, due to cost constraints, even if there is a method that can automatically connect the circuit breaker to the network, if the traditional transmission protocol is used in the process of transmitting device information upwards, due to insufficient network bandwidth, the information upload will be delayed. fail

Embodiment 1

[0108] The present invention proposes an intelligent circuit breaker self-describing information interaction method based on the Lwm2m protocol, such as figure 1 As shown, the method includes:

[0109] Step 101: After the smart circuit breaker registers with the side device, the smart circuit breaker performs a request-response interaction process of self-describing information with the side device based on the resource definition method of the Lwm2m protocol;

[0110] Step 102: The smart circuit breaker performs an interactive process of subscription and publication of self-describing information with edge devices based on the resource definition method of the Lwm2m protocol.

[0111] Before step 101, the establishment of the registration process includes:

[0112] The following client is the smart circuit breaker, and the server is the edge device.

[0113] Combine the device self-description access process of the smart circuit breaker with the client registration mechanis...

Embodiment 2

[0126] A self-describing information interaction method for intelligent circuit breakers based on the Lwm2m protocol, such as image 3 As shown, the method includes:

[0127] Step 201: After the side device registers with the smart circuit breaker, the side device performs a request-response interaction process of self-describing information with the smart circuit breaker based on the resource definition method of the Lwm2m protocol;

[0128] Step 202: The side device performs an interactive process of subscription and release of self-describing information with the smart circuit breaker based on the resource definition method of the Lwm2m protocol.

[0129] According to the information template, the server sends a request message to the client to obtain the required self-describing information. If too much information is required, the request can be sent in fragments.

[0130] After obtaining the complete information, the server uses the subscription mode to subscribe to so...

Embodiment 3

[0133] For the network topology, in addition to the above-mentioned self-describing mechanism, the following methods will be adopted to ensure reliable transmission and "device-edge-cloud" synchronization. The process is based on Figure 4 Execution, including:

[0134] (1) After receiving the complete self-description information, the edge terminal will package the obtained self-description information according to a certain format, and report it to the cloud.

[0135] (2) The cloud completely stores the self-describing information of the circuit breaker in the database, and builds the network topology based on the information, and presents it on the visualization application.

[0136] (3) Provide an information confirmation mechanism for information interaction between "device-edge-cloud", especially "device-edge" interaction. According to the information template received from the registration message, the "edge" detects whether the request sent out is correctly responded,...

Abstract

The invention relates to an intelligent circuit breaker self-description information interaction method and system based on an Lwm2m protocol, and the method comprises the steps: enabling an intelligent circuit breaker to carry out the self-description information request response interaction process with side equipment based on a resource definition mode of the Lwm2m protocol after the intelligent circuit breaker and the side equipment are registered; wherein the intelligent circuit breaker carries out a subscription and release interaction process of self-description information with the side equipment based on a resource definition mode of an Lwm2m protocol. According to the method and the device, the problem of insufficient network bandwidth caused by using a traditional transmission mode is solved by utilizing the characteristic that the lightweight message is transmitted by using the lightweight Internet of Things protocol Lwm2m. According to the invention, a set of network topology of an end-edge-cloud model is also established, so that reliable transmission of self-description information is ensured, and hierarchical management of equipment is realized.

Description

technical field [0001] The invention relates to the field of computer-network-Internet of Things, in particular to a self-describing information interaction method and system for an intelligent circuit breaker based on the Lwm2m protocol. Background technique [0002] The gradual development of the smart grid has brought about a rapid increase in electrical equipment. In order to ensure the safety of a large number of equipment, smart circuit breakers should be equipped for various equipment, and the link of the corresponding link should be closed in time to ensure the safety of electricity when a dangerous situation is found. [0003] The rapid increase in the number of devices has brought obvious problems to the installation of circuit breakers: if the traditional method of manually connecting devices to the network is used, firstly, because of the large number of devices, the management of circuit breakers will be a responsible issue. Even if a dangerous situation is foun...
