Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings.
The invention relates to a real-time monitoring method for abnormal state of cabin networking, which comprises the following steps,
1) a vehicle networking state embedded point module is arranged at a vehicle end in advance to collect networking state embedded point data;
2) uploading the collected networking state buried point data, interface calling and heartbeat message data to a cloud end;
3) the cloud forwards the related data to the Internet of vehicles platform through the message queue Kafka;

5) if the network connection is abnormal, sending an abnormal alarm prompt and giving an abnormal state category; the vehicle networking state embedded point module is used for basic network platform level monitoring; interface calls and heartbeat messages are used for application level network monitoring.
The real-time monitoring of the abnormal state of the cockpit networking comprises basic network platform level monitoring and application level network monitoring, wherein the basic network platform level monitoring is mainly realized on the basis of a vehicle networking state point burying module and assisted by a flow processing rule judging module, and the application level network monitoring is realized on the basis of interface calling and heartbeat messages and assisted by the flow processing rule judging module. The basic network platform level monitoring comprises monitoring for realizing the underlying network residence state and apn configuration, and the application level network monitoring realizes network monitoring for application level (comprising 4Gapp and core interface service), and the framework of the monitoring is shown in figure 1.
For basic network platform level monitoring, the basic networking state is monitored and collected through the vehicle networking state embedded point module. The embedded point service can perform timed polling, judge whether indexes such as the underlying network residing state and apn configuration meet uploading conditions, access a vehicle machine interface when the uploading conditions are met, and upload embedded point logs to a vehicle networking platform according to embedded point specifications.
And uploading the data of the embedded points of the networking monitoring indexes to a cloud end in real time, and forwarding a cloud end signal through a message queue Kafka. The flow processing rule judgment module monitors the networking abnormity in real time and depends on flink flow processing, and the drools rule engine judges and classifies the networking abnormity of uploading embedded point signals in a certain time window according to a preset monitoring alarm rule, so that the basic network platform level networking state monitoring is realized. FIG. 3 is a flow chart of a flow processing rule decision module according to the present invention.
The point-embedded module of the vehicle-machine networking state is connected with the point-embedded service of the vehicle-machine networking state, and the vehicle-machine operating system and the vehicle-machine networking platform can monitor and collect basic networking state indexes and upload networking state point-embedded logs.
And after the vehicle is powered on, the operating system is started, and the vehicle networking state embedded point service is started through system scheduling. On the one hand, whether the point log is buried in the networking state of the vehicle machine meets the uploading condition or not is judged through timed polling, the point log which is not uploaded is read after confirmation, the vehicle machine interface is accessed, the point data is buried in the networking state and uploaded to the cloud end in a json format through the point buried interface, and the point log is received and stored by the vehicle networking platform. And on the other hand, the embedded point service starts a networking state monitoring task, broadcasts a networking state change notification when the networking state change is detected, records a networking state change embedded point log, and transmits the networking state to the cloud.
Specifically, the uploading of the buried point logs is carried out when any condition of periodic uploading and change uploading is met, the periodic uploading is to collect the buried point indexes 1 time every 1 minute when the signal intensity is greater than 0 and the network residence state is greater than or equal to 4G, and the change uploading is to immediately upload when the network residence state is changed from other states to 4G or the signal intensity is changed from 0 to greater than 0. Fig. 2 is a flow chart of acquisition of a cockpit networking state buried point module according to the present invention. The basic network platform level monitoring of the invention realizes the monitoring of the bottom layer network residence state and apn configuration, and mainly collects the voice network residence, the data network residence, the bottom layer apn configuration and the bottom layer ping hectometer state.
And uploading the data of the embedded points of the networking monitoring indexes to the cloud end in real time through the rules, and after receiving the continuously uploaded data, transmitting the data to a kafka message queue for forwarding. Gathering and processing events in a preset time window through flink stream processing, identifying and recording abnormal states of the vehicle-machine networking by using the transmitted rules, and monitoring and alarming the abnormal states according to the monitoring and alarming rules.
The monitoring alarm rule real-time judgment module classifies the networking abnormity according to the uploading embedded point signal, and marks the networking abnormity when the data networking is not a normal value or the voice networking is not a normal value, and the belonged alarm degree is the basic network platform level abnormity alarm.
The APN configuration of the terminal is issued by the cloud platform, after the terminal is connected with the platform each time, the THU pulls the latest APN configuration through calling an interface and is used for dialing next time, and whether the wrong APN configuration is issued or not can be found through an APN configuration buried point. The APN configuration of the mobile sim card and the Unicom sim card are different, if the APN is used wrongly, dialing cannot be successful, and the natural PDN cannot be established. A card operator corresponding to the terminal is taken through the equipment ID, according to different operators, when the operators move, the configuration of the bottom layer APN is judged, and when APN1 configures non-CMIOT and APN2 configures non-standard APN configuration information, APN configuration abnormity is marked; if the card operator is connected, the judgment standard is as follows: APN1 or APN2 triggers an underlying network platform level exception alert when it is not standard APN configuration information.
The application level network monitoring is mainly monitored through interface calling and heartbeat messages. The server and the vehicle end are interacted in a long connection mode, the connection is maintained by timing heartbeat of the vehicle end after the connection of the vehicle end and the server is carried out, and the connection is immediately reinitiated after the vehicle end detects that the connection is disconnected. If the connection is failed to be established, the mobile terminal retries every 10 seconds. The abnormal condition of the networking state can be monitored by using interface calling and heartbeat message data frequency, and the monitoring alarm of the abnormal state of the application cascade network can be triggered when certain rules are met.
When the specific abnormal category is judged, a vehicle ignition event is detected on the same day from 00:00 to 24:00, and if a connection (any interface calling) event of the HU is not monitored in the next hour, the HU network is marked as abnormal. And when Tbox heartbeat data is not monitored within one hour after the HU connection (any interface calling) event is detected on the same day from 00:00 to 24:00, marking the TBox network as abnormal, and triggering an application-level network monitoring alarm.
The invention collects the key index of the networking state and alarms the abnormal state; the flow processing rule-based judgment module judges data and a voice network-residing state, continuously monitors vehicles at buried points, carries out directional analysis on frequently-alarming vehicles, explores network problems, optimizes networking performance and improves user experience.
