Detailed Description
The core of the application is to provide an operation and maintenance management method, device and system for the Internet of things equipment based on the COAP protocol, an operation and maintenance management platform and a readable storage medium, so that the integrity of interaction between the operation and maintenance management platform and the Internet of things equipment is improved while the safety of the interaction process is ensured, and the consumption of a memory and a network is reduced.
In order to better understand the aspects of the present application, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following describes an embodiment of an operation and maintenance management method for an internet of things device based on a COAP protocol, referring to fig. 1, the embodiment is applied to an operation and maintenance management platform, and includes the following steps:
s101, subscribing state change events of the Internet of things equipment according to a subscription mechanism of the COAP protocol;
s102, when the state change event occurs to the Internet of things equipment, acquiring a notification message based on a COAP protocol generated by the Internet of things equipment;
and S103, performing corresponding operation and maintenance management operation locally according to the notification message, or generating an operation message based on a COAP protocol and sending the operation message to the Internet of things equipment so that the Internet of things equipment can perform corresponding processing operation according to the operation message.
The embodiment is realized based on a COAP protocol (Constrained Application Protocol, limited application protocol), and mainly aims to realize operation and maintenance management of the internet of things equipment. The COAP protocol is a network transmission protocol based on a REST model and is mainly used for lightweight M2M communication.
In this embodiment, as shown in fig. 2, the operation and maintenance management system framework of the internet of things device based on the COAP protocol is that the internet of things device is a managed device and is a generator of data, so that the internet of things device in different application scenarios can be specifically an ammeter device, a relay device and a gateway device by using the COAP Server; the management end is the operation and maintenance management platform of the embodiment, and uses the COAP client, and the operation and maintenance management platform can use methods such as get, put, post, delete provided by the COAP protocol to achieve operations such as parameter acquisition, modification, addition and deletion of the internet of things equipment. It should be noted that in this embodiment, different internet of things devices use different addresses URI-host, and different parameters use different paths URI-path, so that different internet of things devices and device parameters can be easily distinguished.
In this embodiment, the operation and maintenance management platform may subscribe to a state change event on the internet of things device according to a subscription mechanism of the COAP protocol, and after the subscription is successful, each time the state change event occurs on the internet of things device, a corresponding notification message is sent to the operation and maintenance management platform, so that monitoring on the internet of things device is realized based on the notification message. The state change event may be selected according to actual requirements, and specifically, the state change event may include any one or any combination of the following: an online event, an alarm event, a fault event, an upgrade event, and a route change event.
In this embodiment, after receiving a notification message of an internet of things device, the operation and maintenance management platform may be divided into the following two cases according to specific situations of the notification message: or executing corresponding operation and maintenance management operation locally, or generating an operation message and sending the operation message to the Internet of things equipment, and executing corresponding processing operation by the follow-up Internet of things equipment according to the operation message. Because the operation and maintenance management requirements are different for different state change events, the selection of the two conditions can be determined according to the instant requirements in the actual application scene. For example, when the state change event is the fault event, maintenance cannot be automatically performed, so that fault prompt information can only be generated on one side of the operation and maintenance management platform to prompt an operation and maintenance person to maintain the fault event. When the state change event is an online event, the operation and maintenance management platform can automatically realize a subsequent processing process, such as identifying the validity of the current online Internet of things equipment, and collecting basic equipment information of the Internet of things equipment.
As a preferred embodiment, TLS may be used to encrypt transmissions for some security-required data, such as the operation messages described above, to improve security.
Particularly, in this embodiment, both the notification message sent by the internet of things device to the operation and maintenance management platform and the operation message sent by the operation and maintenance management platform to the internet of things device are messages based on the COAP protocol. In the operation and maintenance management process of the whole Internet of things equipment, the Internet of things equipment and the operation and maintenance management platform are communicated through a COAP protocol. Whereas the COAP protocol has the following advantages: the COAP protocol has a perfect interaction mechanism, and can realize the operation and maintenance management function of the equipment of the Internet of things; the COAP protocol is realized based on UDP, the cost of the protocol and the network is much lower than that of TCP, and the COAP protocol is more suitable for the scene of the low-power-consumption Internet of things; the COAP protocol provides a confirmation frame and retransmission mechanism, so that the unreliable transmission problem of UDP is solved; the message overhead of the COAP protocol is small, and the consumption of network traffic and the consumption of electric quantity during transmission can be saved greatly.
In summary, the method for managing operation and maintenance of the internet of things device based on the COAP protocol provided in the present embodiment is applied to an operation and maintenance management platform, and the scheme includes: subscribing state change events of the Internet of things equipment according to a subscription mechanism of the COAP protocol; when the state change event occurs to the Internet of things equipment, acquiring a notification message based on a COAP protocol generated by the Internet of things equipment; and according to the notification message, performing corresponding operation and maintenance management operation locally, or generating an operation message based on the COAP protocol and sending the operation message to the Internet of things equipment so that the Internet of things equipment can perform corresponding processing operation according to the operation message. Therefore, the operation and maintenance management function of the internet of things equipment is realized by utilizing the self-perfected interaction mechanism of the COAP protocol, the integrity and the safety of the interaction process are ensured, in addition, the COAP protocol is realized on the basis of UDP, so that the overhead on a memory and a network is much smaller than that of TCP, the COAP protocol is more suitable for the scene of the low-power-consumption internet of things, and the reliability of the data transmission process is improved by the confirmation frame and the retransmission mechanism provided by the COAP protocol.
The second embodiment of the operation and maintenance management method for the internet of things equipment based on the COAP protocol provided by the application is implemented based on the first embodiment, and is expanded to a certain extent based on the first embodiment.
Specifically, the embodiment describes corresponding monitoring and controlling processes in detail for different state change events, and the following describes the situations that the state change events are an online event, a fault event and an upgrade event respectively. In an actual application scenario, the monitoring control process of the state change event being another event may refer to the present embodiment, but this embodiment will not be described one by one.
As shown in fig. 3, when the state change event is an online event, the embodiment includes the following steps:
s301, subscribing an online event of the Internet of things equipment according to a subscription mechanism of the COAP protocol;
s302, when an online event occurs to the Internet of things equipment, acquiring an online notification message based on a COAP protocol generated by the Internet of things equipment;
the above-mentioned on-line event may specifically be power-up or reset.
S303, judging whether the Internet of things equipment has warehousing rights or not according to the online notification message; if yes, jumping to S304, otherwise refusing the Internet of things equipment to be on line;
s304, allowing the Internet of things equipment to be online and put in storage, and monitoring the online state of the Internet of things equipment through a heartbeat mechanism;
s305, calling a get interface of the COAP protocol to acquire basic equipment information of the Internet of things equipment.
In this embodiment, the operation and maintenance management platform subscribes to the online event of the internet of things device through the subscription mechanism of the COAP protocol, so when the internet of things device is powered on or reset, the internet of things device generates an online notification message based on the COAP protocol and sends the online notification message to the operation and maintenance management platform; then, the operation and maintenance management platform judges whether the Internet of things equipment for sending the online message is legal or not, and if so, the Internet of things equipment is allowed to be online and put in storage; the operation and maintenance management platform subscribes to the heartbeat message of the Internet of things equipment so as to maintain the online state of the Internet of things equipment, and meanwhile, the Internet of things equipment needs to periodically send heartbeat packets to the operation and maintenance management platform; after the Internet of things equipment is online, the operation and maintenance management platform can also acquire basic equipment information of the Internet of things equipment through a get interface of the COAP protocol.
As shown in fig. 4, when the state change event is a fault event, the embodiment includes the following steps:

s403, determining the fault type and generating a corresponding operation and maintenance work order and prompt information according to the fault notification message.
In this embodiment, the operation and maintenance management platform, as a management end, may acquire basic device information of the internet of things device, and subscribe to a state to be monitored, such as an alarm event, a fault event, etc., on one side of the internet of things device through a subscription mechanism of the COAP protocol.
Specifically, when the internet of things device detects an event such as a fault, the internet of things device can generate a fault notification message through a COAP protocol, and after the operation and maintenance management platform receives the fault notification message, a corresponding work order and prompt information can be generated according to the fault type, so that maintenance personnel can be dispatched to maintain the device conveniently.
It can be understood that the operation and maintenance management platform can subscribe to a fault release event of the internet of things device, and after the fault of the internet of things device is released, the internet of things device can report the fault release to the operation and maintenance management platform by the same mechanism, and the operation and maintenance management platform recovers the corresponding state.
As shown in fig. 5, when the state change event is an upgrade event, the embodiment includes the following steps:
s501, subscribing to an upgrade event of the Internet of things equipment according to a subscription mechanism of the COAP protocol;
the upgrade event can be understood as an upgrade request, specifically, the internet of things device can automatically detect whether the firmware of the internet of things device needs to be upgraded, and when the update is determined to be needed, the upgrade event is considered to occur.
S502, when an upgrading event occurs to the Internet of things equipment, acquiring an upgrading notification message based on a COAP protocol generated by the Internet of things equipment;
s503, splitting a target upgrade package according to the upgrade notification message, and writing a splitting result into an operation message based on a COAP protocol in a block mode;
s504, calling a post interface of a COAP protocol to send the operation message to the Internet of things equipment in a multicast mode until no message remains;
s505, judging whether the Internet of things equipment sends a package supplementing request in a preset time period; if yes, jumping to S506, otherwise judging that the data transmission of the upgrade package is finished, and jumping to S507;
s506, corresponding operation messages are sent to the Internet of things equipment in a unicast mode;
s507, the equipment of the Internet of things executes upgrading operation.
In this embodiment, for large file transmission such as firmware upgrade packages of the internet of things devices, when batch upgrade is needed, the large file transmission can be issued in a multicast mode, so that a client is prevented from repeatedly sending data for many times, and in addition, excessive sub-package issuing can be avoided by using a block transmission mode, so that a plurality of internet of things devices can be timely and quickly received to an upgrade data package issued by an operation and maintenance management platform.
Specifically, in the power operation and maintenance scenario, the electric meter acquisition terminal is used as a COAP server, the power operation and maintenance management system is used as a COAP client, and the power operation and maintenance management system and the electric meter acquisition terminal interact by using a COAP protocol, so that the following operation and maintenance management functions can be realized based on the embodiment of the method:
