Examples
The embodiment of the invention discloses a system for guaranteeing the stable operation of a gateway, which is applied to the gateway provided with a power module capable of being controlled remotely, and the gateway is also provided with a plurality of network modules; as shown in fig. 1, the system includes:
a detection module 101, configured to detect whether the gateway is online, and restart the gateway based on the power module when the gateway is not online;
specifically, the power module includes: the gateway can be restarted through the power module, and the standby battery can be automatically switched to by setting the standby power supplies when the gateway is not connected with the power supply for some reasons; when the gateway is connected with a power supply, the standby battery can be charged regularly, so that the electric quantity of the battery is ensured to be sufficient. In this way, as shown in fig. 3, the detection module 101 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 in the preset time, carrying out multiple online detection data packet retransmission to the gateway; and restarting the gateway through the remote power control module if the specific data packet fed back by the gateway is not received within the preset time after the retransmission.
Specifically, the detection module 101 combines with a remote power control module on the gateway, and based on the intelligent monitoring server, periodically sends an online detection data packet to the 6060 port of the gateway through the TCP protocol, and then the gateway returns a specific data packet to indicate that the gateway is in an online state. When the gateway does not return the data packet within the appointed 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 default gateway is powered off, then the gateway server is restarted through the remote power control module, and if the gateway still is in a power-off state after a restart instruction is issued, the gateway is considered to be powered off manually.
The monitoring module 102 is used for monitoring the running state of the gateway and repairing the fault when the fault is monitored; specifically, if the gateway is in an on-line state, the monitoring module 102 is started to perform work, and specifically, as shown in fig. 3, the monitoring module 102 includes: the system comprises a system resource monitoring sub-module, a network link monitoring sub-module, a data channel monitoring sub-module, a program integrity monitoring sub-module and a program functionality monitoring sub-module.
Specifically, as shown in fig. 4, the system resource monitoring submodule is configured to monitor the disk space occupancy rate of the gateway periodically, and perform disk cleaning when the disk space occupancy rate is greater than a first threshold of the disk; if the occupancy rate of the cleaned magnetic disk is larger than a first threshold value of the magnetic disk, alarming by the alarming module; if the occupancy rate of the cleaned magnetic disk is larger than a second threshold value of the magnetic disk and is not larger than the first threshold value, reducing the monitoring time interval;
the gateway is also used for regularly monitoring the CPU occupancy rate and the memory occupancy rate of the gateway, and cleaning the process of the gateway if the CPU occupancy rate or the memory occupancy rate is larger than the corresponding occupancy rate threshold; 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 larger 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, processes and the like through various program languages, and periodically acquires the size of the residual disk space, the CPU occupancy rate, the memory occupancy rate and the process number of the gateway server. When the disk space of the gateway server is found to occupy more than 80%, firstly cleaning a data log generated by the intelligent monitoring acquisition system before one month, reported data in a database and large files generated by a non-system, and if the disk space is less than 60% after the data log, the reported data in the database and the large files generated by the non-system are considered to be normal. If the occupancy rate of the magnetic disk is more than 60% and less than 80% after cleaning, the magnetic disk space detection period is shortened; if the disk occupancy rate is greater than 80% after cleaning, the disk space is considered to be insufficient, and mail warning is carried out. When the occupancy rate of the CPU and the memory exceeds 90%, all unnecessary processes (the necessary processes refer to processes required by an operating system process and intelligent monitoring software) and repeated processes generated by manual operation are cleaned, and if the occupancy rate of the CPU is lower than 90%, the CPU is considered to be normal. And the process monitoring is used for assisting the CPU and the memory monitoring, so that useless processes can be cleaned conveniently.
In addition, the gateway is also provided with various network modules; specifically, for example, wifi modules, 3G/4G/5G modules, and the like may be included. Therefore, as shown in fig. 5, the network link monitoring submodule actively detects the network quality in the environment of the IPV4 and the IPV6 by adopting a network probe, analyzes the network speed and the network quality, and is specifically used for periodically testing the time delay and the packet loss rate of the network link of the gateway;
if the time delay is larger than the preset time value and the packet loss rate reaches a first preset packet loss threshold value, selecting other network modules to perform network switching and performing network link testing; if network modules capable of being conducted by the network exist, selecting the network module with the best network link quality from the network modules to conduct network connection; wherein the other network modules are different from the current network module of the network link;
if the network of the current network link is not conducted based on the time delay and the packet loss rate, judging whether the next hop in the network link is reachable or not; if the next hop is reachable, selecting other network modules to perform 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 recovering the network configuration; 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 network module with the best current is larger than a second preset packet loss threshold value, shortening the time interval of the periodic test.
Specifically, as shown in fig. 5, the network link monitoring submodule invokes the scampe network probing tool of the caida on each gateway through the written probe program, sends ICMP (Internet Control Message Protocol, which is a sub-protocol of the TCP/IP protocol cluster and is used for transferring control messages between the IP hosts and the routers, and the control messages refer to messages of the network itself such as network connectivity failure, host availability, routing availability, etc., and these control messages play an important role in transferring user data though not transferring user data), ICMPv6 data packets for performing tracerout test under the protocols of IPV4 (Internet Protocol version, internet protocol version 4) and IPV6 (Internet Protocol version, internet protocol version 6), and obtains time delay, jitter and packet loss rate of each node between the gateway and the upper layer server. When the gateway link delay is more than 1000ms and the link packet loss rate reaches 10%, the network link quality is considered to be poor. When the network link quality is poor, recording the current network connection mode, attempting to switch the network among the wired network, the WIFI network and the 4G network, testing the state of the network link, and if all the network connection modes are shown as poor in network link quality through testing, comparing the network, and selecting the optimal network connection mode. When the display network is not enabled, firstly judging whether the next hop is reachable through a tracerout command, and if the next hop is reachable, considering the next hop as a fault of other nodes in a network link, switching among the wired, WIFI and 4G; and if the next hop is not reachable, running a network configuration script, and carrying out network configuration again. And finally, if the connection to the destination terminal is still unavailable, sending the fault mail.
Specifically, as shown in fig. 6, the data channel monitoring submodule is configured to: when the HTTP data channel from the gateway to the intelligent monitoring server is monitored to be blocked, the network link monitoring sub-module is called to process so as to ensure that the HTTP channel is recovered to be normal;
the system is also used for periodically sending data packets to the 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, the data packet sending speed is reduced within a preset time;
if the MQTT data channel is monitored to be still blocked after the reduction operation, the data packet sending speed is further reduced within the preset time; if the MQTT data channel is monitored to be still blocked after the operation is further reduced, alarming is carried out through the alarming module;
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 recovery operation, alarming is carried out through the alarming module;
the gateway is also used for reducing the data sending speed when the blocking of a data channel of a message queue in the gateway is monitored; restarting a receiving process if the message queue data channel is still blocked after the data sending speed is reduced; and if the message queue data channel is still blocked after restarting the receiving process, alarming by the alarming module.
Specifically, as shown in fig. 6, the data channel monitoring submodule monitors mainly through data transceiving conditions, and there are three types of data channels for the data channels: the HTTP channel from the gateway to the intelligent monitoring server, the MQTT (Message Queuing Telemetry Transport, message queue telemetry transport) data channel from the gateway to the intelligent monitoring server and the message queue data channel inside the gateway are respectively. MQTT is a publish/subscribe paradigm based message protocol under the ISO standard (ISO/IEC PRF 20922), which works on the TCP/IP protocol family and is designed for low hardware capability remote devices and poor network conditions.
For HTTP data channel, network layer connection is mainly involved, so stability is guaranteed by network link monitoring sub-module.
For the MQTT data channel, channel clear detection is performed by periodically sending HELLO packets via the MQTT data channel 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 data packet sending speed is slowed down, and the data packet is maintained for 5 minutes for retesting. If the data packet is still in the blocking state, blocking information is sent to the server, and then the sending speed of the data packet is further reduced for 5 minutes. If the data packet is still blocked, sending an alarm mail, otherwise, recovering the sending speed of the data packet.
And C program is adopted for detecting the message channel in the gateway, and a sys/msg module is called to obtain the data volume, the last storage time and the last reading time of the data in the message queue. If the last reading time of the data is two minutes before the last storing time, restarting the reading process of the message queue. A specific decision tree is shown in fig. 6.

the gateway is also used for periodically detecting whether the software of the gateway is missing; if the software is missing, installing the missing software; if the installation fails, installing the missing software based on the source code; and if the source code is failed to be installed, alarming is carried out through the alarming module.
Specifically, the program integrity monitoring submodule periodically detects whether all executable files, configuration files and software packages necessary on the gateway exist through configuration files prepared in advance, detects whether software versions required by system operation are matched with operating system versions, and then detects whether all processes which should exist run in a correct mode. After the program integrity state detection is completed, if a missing executable program exists, starting is performed under a corresponding folder, if a missing configuration file exists, generating is performed under a standby folder, and if software required by the operation of the intelligent monitoring system is missing, automatic installation is performed. A specific decision tree is shown in fig. 7.

If the data acquisition still does not exist after the operation, identifying whether the version number of the corresponding protocol analysis program is the latest version, and if not, downloading the latest file to the server to update the program. And if the data acquisition still does not exist after the operation, carrying out alarm operation.
The system is also used for testing whether the video equipment for collecting the video data stream is online 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, inquiring whether a local video stream exists or not; if yes, the network module is called for processing; and if the video equipment is judged to be not present, resetting the configuration of the video equipment.
Taking video acquisition and uploading by a camera as an example for explanation, the program functional monitoring submodule is mainly responsible for detecting whether the data acquisition and video transmission functions are correct. 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 but the data is not acquired, calling a program integrity monitoring sub-module at the first time; and if the data is acquired, calling a data channel monitoring sub-module at the first time. If no video is uploaded, firstly, the camera connected to the gateway is tried to be connected, and if the camera can be connected to, the camera related configuration is reset. A specific decision tree is shown in fig. 8.
