Due to the complex structure of the crane system, the harsh working site environment, and various improper use situations, major safety accidents often occur in the production and operation of enterprises. Therefore, we urgently need to use various system detection and diagnosis methods and various monitoring system diagnosis data methods from the perspective of lifting system detection and analysis, and use the different characteristics of various detection and diagnosis data to accurately identify the normal operation of the large crane system Status provides a reliable basis for the development of predictive system maintenance and maintenance management. The artificial neural network system is a completely non-linear dynamic network system built by itself by imitating the various functional processing structures of various types of human brain neurons. Due to its good man-machine association automatic memory, automatic organization, automatic learning and nonlinear dynamic mapping computing capabilities, the artificial neural network system has developed into an effective way for enterprises to solve the problem of large-scale crane machinery fault detection, diagnosis and processing.
The problem of poor connectivity is easy to be discovered by people, and its main specific manifestations are: hardware, media, network software infrastructure facilities are often out of power, such as bus routers, switches, hubs, power supplies and other network hardware infrastructure equipment, as the network connection time continues Overtime or man-made damage, the hardware equipment functions aging or failure; network software system configuration function error, etc. This is a relatively common bus network failure; basic equipment hardware compatibility issues cause the normal construction of computer bus networks often require a large number of networks The basic equipment, from the PC of the network terminal to the bus router is a network equipment core of the switch, and it is also very likely to be composed of a set of network basic equipment software of many network manufacturers. If the user's network connection device does not support compatibility, it may cause network connection problems.
In the daily use of computer networks, network failures inevitably occur. Any damage to the hardware or network logic may directly lead to the security problem of the entire computer wireless network. In fact, the sudden appearance of network problems is not terrible. The key is that we must discover network failures in time and eliminate them in time, so as to realize the smooth flow of the national computer international network information system as soon as possible and better provide services to the public.
In order to effectively eliminate local line mechanical damage when line mechanical faults occur, the faults can be divided into two types: medium and long distance and medium and short distance line faults. In a short distance, it is usually possible to interrupt and connect a host port of a network host line to an interrupt port where the host can work normally, and then connect a part of the network host port to another port, according to the interruption of the network line Connection or network interruption to accurately determine its specific situation. For this kind of long-distance cable fault, we suggest that you can consider using a professional laser network cable fault tester. For complex electromagnetic interference, the complex magnetic field can be effectively avoided, and the automatic interference elimination method can be used to quickly troubleshoot the fault.
The port setting can be performed automatically by directly opening and manually closing the power signal light port. For some router network failures and hub short-circuit failures, they can usually be temporarily connected to a normal network cable or virtual host. If they are working properly now, it can even prove that they should all be normal. If it does not operate normally, you can consider continuing to try to use the software for quick troubleshooting methods to quickly troubleshoot the fault.
You should start with logic, eliminate logical faults, and eliminate computer network faults by checking the configuration.
For this kind of connection problem, it is usually necessary to recheck whether the connection between the two ports has been completed. If there is no such connection, it can automatically check whether the port connection has been closed. If it has been closed, you only need to restart this port to easily solve the problem.
For such problems, we will first check whether the network card driver has been installed, if not, please install the driver. If the network card driver has been installed, you need to check whether the network card driver is installed correctly. If the installation is not correct, solve the problem in time.
Obtain fault alarm and network performance fault information through the communication network fault management system, and automatically locate network faults. Some network companies have used a real-time network traffic management and monitoring system called suncom, which can perform real-time management of all network communication equipment traffic of the entire network company. Usually, the system can observe and monitor the network load utilization rate of each communication device and the network traffic of each communication line in real time. When someone reports that the network cannot be connected in real time or the network speed is very slow, you can use the network management monitoring system to observe the network connection operation between the network computer and the network switch in real time, whether the connection is sometimes disconnected, and whether the switch has a high level of efficiency in processing the load. Is the traffic consumption on the line large? By observing the operating status of the abnormal ports of each device, analyze and observe in real time which device port of each switch has been connected to virtual computer packages or data network packets that have reached the number of abnormal ports.
Frequently check the running logs of all network management equipment in real time and analyze the running status of the network equipment in time. Observed through a command line observer, a switch connected to me under the switch is often interrupted every hour. Later, due to the long network interval, the staff of the unit did not really feel that the network was interrupted frequently. During this period, we checked and determined that the wireless optical cables, optical transceivers, network cables, switch bus configuration, and each switch bus port were all normal. After that, the standby interval was shortened from the original hour to minutes. Therefore, we immediately automatically determine whether the wireless switch itself has a network failure, and manually replace a spare wireless switch that has been prepared, which greatly shortens the time after network failure recovery processing, and quickly restores the wireless network in the fastest and shortest time.
The replacement method is to use a normal object to replace an abnormal object, so as to achieve the purpose of fault location and elimination. The object here can be a piece of cable, a device or a module.
The query can analyze the current fault configuration display data of the above-mentioned equipment, and accurately locate the equipment fault by querying and analyzing whether the data displayed after the above-mentioned equipment configuration is normal. If the reconfigured system data contains any errors, it may need to be reconfigured.
In order to ensure the timely and accurate diagnosis and effective elimination of enterprise network faults, restore the normal operation of the enterprise network in a timely manner at the fastest network speed, and effectively ensure the operational reliability and efficiency of the enterprise network, special attention should be paid to the following key issues: Study and establish a comprehensive and complete network computer room network equipment maintenance business management documents (mainly including service computer room network management equipment maintenance business procedures, network maintenance attendance information management equipment maintenance business procedures, network failure incident emergency handling plans, network topology management structure diagrams, etc. ), network-related information materials such as the download and distribution of technical manuals for network maintenance equipment and software use, the distribution of network equipment IP tables and address tables, etc., can be browsed or inquired online for daily network equipment maintenance business management and technical training network learning. The second is to pay close attention to the research and development of new basic theories and new application technologies for network security maintenance system management in domestic and foreign enterprises, continuously strengthen the research and study of the theoretical knowledge of relevant domestic enterprises’ network maintenance application technologies, actively explore network practices, and continuously improve their own Hands-on ability and proficiency in the actual use of a set of related enterprise network security maintenance system management software. The third is to effectively strengthen the management of daily on-duty network system maintenance tasks, strictly implement the relevant regulations on daily on-duty network maintenance task management, clarify the responsibilities of network managers and the content of task management, conduct regular inspections and on-duty maintenance, and monitor the daily operation and management of the network system in real time. Discover all kinds of network faults and deal with them in time.
The sudden occurrence of computer wireless network failure is often inevitable. After the network project is completed and commissioned, the analysis, diagnosis and troubleshooting of network faults is an important prerequisite for ensuring the normal and stable operation of the network. Effectively do a good job in system network fault analysis and diagnosis and network fault analysis and elimination, improve the success rate of network fault analysis and detection, and reduce detection failures. One is to have basic knowledge to master network capabilities, related network fault operations and basic knowledge of system maintenance, and to continuously participate in learning and improve the knowledge network system; the second is to understand various network infrastructure and system components, such as network topology, hardware communication equipment network The application of software network related technologies such as connection, system network parameters and data harmony; third is to be familiar with the output of system parameter data of different network fault diagnosis objects when network failures occur during the operation of different network systems.
