Description
Technical Field
The invention relates to the technical field of nuclear fusion control, in particular to a monitoring method, a monitoring system, a monitoring terminal and a monitoring medium of a nuclear fusion control system.
Background
The EPICS Channel Access protocol analysis is a packet sniffer and network protocol analyzer running on most computer platforms, for example: windows, OS X, Linux, and UNIX. It is a free source software in C language, and is issued following GPL2 public license. To capture packets, wirereshark uses the pcap library, which allows for sniffing of traffic from many different network types, including ethernet, IEEE 802.11, PPP, bluetooth, and USB, captured traffic can be stored and opened. In addition to the natively supported tcpdump (libpcap) format, other trace file formats, such as: snorop, Microsoft Network Monitor, etc. are also supported. To analyze the captured flow, wirereshark supports the dissection of hundreds of different protocols. To extend its initial set of functionality, wirereshark also provides support for plug-ins. The Channel Access protocol analysis is implemented by a plug-in.
The original implementation of the CA dissector plug-in for WireShark was done by Ron Rechenmacher. It is not a complete solution because only part of the most common CA message types are supported partially and are not compatible with the latest version of Wireshark. Thus Cosylab, KEK, Fermilab laboratories have collaborated to develop a new CA dissector insert for wiresharp. The tool allows Channel Access (CA) traffic to be captured directly from the network and interpreted content using a graphical or textual user interface.
At present, the system control and monitoring method in the prior art generally calls data for each subsystem separately, and uses different protocols with each other, and the time of the calling mode is delayed, so that the certainty of problem positioning cannot be ensured. In the field of nuclear fusion control, due to the particularity of nuclear fusion research, communication among subsystems cannot be timely realized through the existing system control and monitoring method, and faults of a control system cannot be timely eliminated. Therefore, how to research and design a monitoring method, a monitoring system, a monitoring terminal and a monitoring medium of a nuclear fusion control system is a problem which is urgently needed to be solved at present.

In the drawings:
fig. 1 is a system architecture diagram in an embodiment of the invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Example 1: a monitoring method of a nuclear fusion control system is shown in figure 1 and comprises the following steps:
s101: reading the PV name output by the client through a CA protocol, and manually inputting according to the requirement or automatically inputting according to a program;
s102: broadcasting the PV name in the network using the CA protocol;
s103: matching the received broadcast with the corresponding associated subsystem through the IOC program; and if the matching is successful, feeding back the PV value output by the corresponding subsystem to the client to establish channel connection.
It should be noted that the IOC programs and the subsystems in the same network segment are configured in a one-to-one correspondence manner, and all the IOC programs in the same network segment perform synchronous matching on the corresponding subsystems. Furthermore, matching the PV name in the received broadcast against the PV name of the subsystem; and if the PV names are the same, feeding back the PV value output by the subsystem to the client.
The IOC program maintains an operational database in memory, in which the PV values are stored. When a client needs to monitor a certain PV, a broadcast is sent to the network by using a CA protocol, and an IOC program with the PV responds after receiving the broadcast and establishes channel connection with the client to realize the monitoring of the PV.
It should be noted that the PV value is stored in the archive storage server Archiver application. Furthermore, the monitoring of this process does not involve data storage, and it is the PV value within the IOC memory that is monitored, and this value is dynamic.
And after the sub-system is connected with the client side through the channel, the PV value received by the client side and the PV value output by the sub-system are synchronously updated in real time.
For example, system a and system B agree that the PV value is 1 for start, the PV value is 0 for end, system a changes the PV value, system B listens again for the PV value, and when the PV value is found to be 0, system B can perform the next processing in time.
Example 2: a monitoring system of a nuclear fusion control system is shown in FIG. 1 and comprises a client, a CA protocol module and a plurality of IOC modules. And the client is used for outputting the PV name of the object to be monitored. And the CA protocol module is used for broadcasting the PV name in the network by utilizing the CA protocol. The IOC module is used for matching the received broadcast with the corresponding related subsystem; and if the matching is successful, feeding back the PV value output by the corresponding subsystem to the client to establish channel connection.
