As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of the present disclosure belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined in various embodiments of the present disclosure.
Examples
The embodiment of the invention discloses a system for ensuring the stable operation of a gateway, which is applied to the gateway provided with a power module capable of being remotely controlled, and the gateway is also provided with various network modules; as shown in fig. 1, the system includes:
the detection module 101 is used for detecting whether the gateway is online or not and restarting the gateway based on the power supply module when the gateway is not online;
specifically, the power module includes: the gateway can be restarted through the power supply module, and through the setting of the plurality of standby power supplies, for example, when the gateway is not connected with the power supply for some reasons, the gateway can be automatically switched to a standby battery; when the gateway is connected with a power supply, the standby battery can be charged regularly, and the electric quantity of the battery is ensured to be sufficient. Thus, the detection module 101, as shown in fig. 3, is specifically configured to: sending an online detection data packet to the gateway; if the specific data packet fed back by the gateway is not received within the preset time, retransmitting the online detection data packet to the gateway for multiple times; and if the specific data packet fed back by the gateway is not received within the preset time after retransmission, restarting the gateway through the remote power supply control module.
Specifically, the detection module 101, in combination with a remote power control module on the gateway, periodically sends an online detection packet to a 6060 port of the gateway through a TCP protocol based on the smart monitoring server, and then the gateway returns a specific packet to indicate that the gateway is in an online state. When the gateway does not return the data packet within the designated time, the intelligent monitoring server retransmits the data packet twice, if the intelligent monitoring server still does not receive the data packet from the gateway, the gateway is shut down by default, then the gateway server is restarted through the remote power control module, and if a restart instruction is issued, the gateway is still in a shutdown state, and the gateway is considered to be shut down artificially.
The monitoring module 102 is configured to monitor an operating state of the gateway, and perform fault recovery when a fault is monitored; specifically, if the gateway is in the online state, the monitoring module 102 is started to operate, specifically, as shown in fig. 3, the monitoring module 102 includes: a system resource monitoring submodule, a network link monitoring submodule, a data channel monitoring submodule, a program integrity monitoring submodule and a program functionality monitoring submodule.
Specifically, as shown in fig. 4, the system resource monitoring submodule is configured to periodically monitor a disk space occupancy of the gateway, and perform disk cleaning when the disk space occupancy is greater than a first disk threshold; if the occupancy rate of the cleaned disk is greater than a first threshold value of the disk, alarming through the alarming module; if the occupancy rate of the cleaned disk is greater than a second threshold value of the disk and not greater than the first threshold value, reducing the monitoring time interval;
the system is also used for regularly monitoring the CPU occupancy rate and the memory occupancy rate of the gateway, and if the CPU occupancy rate or the memory occupancy rate is greater than the corresponding occupancy rate threshold value, the process of the gateway is cleaned; if the CPU occupancy rate or the memory occupancy rate after the process cleaning is still larger than the corresponding occupancy rate threshold value, performing system cleaning; and if the CPU occupancy rate or the memory occupancy rate after the system cleaning is still greater than the corresponding occupancy rate threshold value, alarming through the alarming module.
Specifically, the system resource state detection submodule monitors system resources such as disk space, CPU, memory, and processes through multiple programming languages, and periodically obtains the size of the remaining disk space of the gateway server, the CPU occupancy rate, the memory occupancy rate, and the number of processes. When the disk space of the gateway server is found to occupy more than 80%, firstly, data logs generated by the intelligent monitoring and acquisition system before one month, reported data still stored in a database and large files which are not generated by the system are cleaned, and if the disk space occupied is less than 60% after the data logs are considered to be normal. If the occupancy rate of the disk is more than 60% and less than 80% after cleaning, the disk space detection period is shortened; and if the occupancy rate of the disk is more than 80 percent after the cleaning, determining that the disk space is insufficient, and performing mail warning. When the occupancy rates of the CPU and the memory exceed 90%, all unnecessary processes (necessary processes refer to processes required by an operating system process and intelligent monitoring software) and repeated processes generated by artificial operation are cleared, and if the occupancy rates of the CPU are lower than 90%, the process is considered to be normal. And the process monitoring is used for assisting the monitoring of a CPU and a memory, so that useless processes are convenient to clean.
In addition, the gateway is also provided with a plurality of network modules; specifically, for example, a wifi module, a 3G/4G/5G module, etc. may be included. Therefore, as shown in fig. 5, the network link monitoring sub-module actively performs network quality detection in the environment of IPV4 and IPV6 by using a network probe, analyzes network speed and quality, and is specifically used for periodically testing the delay and packet loss rate of the network link of the gateway;
if the time delay is greater than the preset time value and the packet loss rate reaches a first preset packet loss threshold value, selecting other network modules for network switching and carrying out network link test; if network modules which can be conducted by the network exist, selecting the network module with the best network link quality from the network modules to carry out network connection; the other network module is a network module different from the current network module of the network link;
if the network of the current network link is determined to be not conducted based on the time delay and the packet loss rate, judging whether the next hop in the network link can be reached; if the next hop can be reached, selecting other network modules to carry out network switching; if the network after the network switching is not conducted, alarming is carried out through the alarming module; if the next hop is not reachable, executing the operation of network configuration recovery; and if the network after the operation is not conducted, alarming through the alarming module.
In addition, the "selecting the network module with the best current network link quality for network connection" includes: and if the packet loss rate of the current best network module is greater than a second preset packet loss threshold, shortening the time interval of the periodic test.
Specifically, as shown in fig. 5, the network link monitoring sub-module calls a scanner network probing tool of caida on each gateway through a written probe program, and sends an ICMP (Internet Control Message Protocol), which is a sub-Protocol of a TCP/IP Protocol cluster, to the smart monitoring server, the camera, and the encoder, so as to transmit Control messages between the IP host and the router, where the Control messages refer to messages of the network itself, such as network access failure, whether the host is reachable, and whether the router is available, and the Control messages are not used for transmitting user data, but play an important role in transmitting user data), ICMPv6 data packets, so as to perform a tracerout test under the protocols of IPV4(Internet Protocol version 4) and IPV6(Internet Protocol version 6), and obtain a delay test from each node between the gateway and the upper-level server, Jitter, packet loss rate. And when the time delay of the gateway link is more than 1000ms and the packet loss rate of the link reaches 10%, the network link quality is considered to be poor. And when the network link quality is poor, recording the current network connection mode, trying to switch the network among the wired network, the WIFI network and the 4G network, testing the network link state, and if all the network connection modes are poor in network link quality after testing, comparing the networks and selecting the optimal network connection mode. When the network is not communicated, firstly, whether the next hop can be reached is judged through a tracerout command, if the next hop can be reached, the next hop is considered to be a fault of other nodes in a network link, and switching is carried out among the wired network, the WIFI and the 4G; and if the next hop cannot be reached, running the network configuration script and carrying out network configuration again. And if the connection to the destination terminal still can not be carried out, sending a fault mail.
Specifically, as shown in fig. 6, the data channel monitoring submodule is configured to: when monitoring that the HTTP data channel from the gateway to the intelligent monitoring server is blocked, calling the network link monitoring submodule for processing to ensure that the HTTP channel is recovered to be normal;
the gateway is also used for periodically sending data packets to an MQTT data channel from the gateway to the intelligent monitoring server; when the MQTT data channel is determined to be blocked based on the returned data delay, reducing the sending speed of the data packet within preset time;
if the MQTT data channel is monitored to be blocked after the reduction operation, the data packet sending speed is further reduced within a preset time; if the MQTT data channel is monitored to be blocked after the operation is further reduced, the warning module is used for warning;
if the MQTT data channel is monitored to be not blocked after the operation is reduced, the sending speed of the data packet is recovered; if the MQTT data channel is monitored to be blocked after the operation is recovered, alarming is carried out through the alarming module;
the gateway is also used for reducing the data sending speed when the blockage of a message queue data channel in the gateway is monitored; if the data transmission speed is reduced and the data channel of the message queue is still blocked, restarting the receiving process; and if the message queue data channel is still blocked after the receiving process is restarted, alarming through the alarming module.

MQTT is a messaging protocol based on the publish/subscribe paradigm under the ISO standard (ISO/IEC PRF 20922), which operates on the TCP/IP protocol suite, and is a publish/subscribe messaging protocol designed for remote devices with poor hardware performance and in situations of poor network conditions.
For the HTTP data channel, the network layer connection is mainly involved, so the stability guarantee is carried out by the network link monitoring submodule.
For MQTT data channels, channel clear detection is performed by periodically sending HELLO packets over MQTT data channels and analyzing the return packets. If the time delay of the returned data packet exceeds 1000ms, the MQTT data channel is judged to be in a blocking state, then the sending speed of the data packet is slowed down, the data packet is maintained for 5 minutes, and the retest is carried out. If the data packet is still in the blocking state, the blocking information is sent to the server, and then the data packet sending speed is further reduced for 5 minutes. If the data packet is still blocked, sending an alarm mail, otherwise, recovering the data packet sending speed.
For the detection of the message channel in the gateway, a program C is adopted, and a sys/msg module is called to obtain the data volume in the message queue, the last storage time of the data and the last reading time of the data. And if the last reading time of the data is two minutes before the last storage time, restarting the message queue reading process. A specific decision tree is shown in fig. 6.
As shown in fig. 7, the program integrity monitoring submodule is configured to periodically detect whether an executable file of the gateway is missing; if the executable file is missing, executing the operation of downloading the missing executable file;

And if the data collection does not exist after the operation, performing alarm operation.
The device is also used for testing whether the video equipment for collecting the video data stream is on line or not when the video data stream is missing; if the video equipment is not on-line, alarming is carried out through the alarming module; if the video equipment is online, whether a local video stream exists is inquired; if yes, calling a network module for processing; and if the configuration does not exist, resetting the configuration of the video equipment.
The explanation is given by taking video acquisition and uploading through a camera as an example, and the program functional monitoring submodule is mainly responsible for detecting whether the data acquisition and video transmission functions are correct or not. If no data is uploaded, detecting whether corresponding equipment of the intelligent monitoring system is online or not and whether data is acquired or not through a corresponding interface, and if the equipment is online and the data is not acquired, calling a program integrity monitoring submodule at the first time; and if the data are acquired, calling the data channel monitoring submodule at the first time. If the video is not uploaded, the camera connected to the gateway is firstly tried to be connected, and if the camera can be connected, the relevant configuration of the camera is reset. A specific decision tree is shown in fig. 8.
