1. Program overview

At present, cranes have been widely used in the industrial field, and various operation safety accidents caused by illegal and over-limit operations of cranes will cause huge losses of life and property. The experience and lessons of safety accidents show that effective supervision of the crane use process is necessary to effectively control the dangerous factors and safety hazards in the equipment operation process. Preventing and reducing the occurrence of crane safety production accidents has become an urgent task.

The "Large Port Crane Safety Monitoring System" monitors the operation of large port cranes such as lifting, trolley, trolley, luffing, rotation, and spreader in real time; it monitors the safety protection devices of each organization in real time, and discovers safety in time through data analysis Hidden hazards to prevent accidents; provide relevant data and necessary records for the reliable operation of various crane agencies.

1. The real-time status monitoring function displays the status information of the current crane's various mechanisms in real time: the status, position, action, electrical parameters, wind speed of the cart, trolley, lifting, pitching, spreader, etc.; auxiliary mechanism status: network communication status, Over-temperature status, lubrication system status, emergency stop status; real-time monitoring of the operation of accident-prone equipment and key key equipment, while analyzing and sorting the collected data, and comparing the real-time data on site and related equipment operation indicators In contrast, when the deviation limit is exceeded, an alarm message is generated and the alarm record is stored.

2. Historical data analysis function Provides historical data storage function, supports various forms of alarm, trend analysis and other functions, which is convenient for accident analysis of field data; supports historical playback function, setting the start and end time and playback of historical playback on the screen The historical process during the failure period will be played according to the set playback speed. The user can also drag the playback progress bar to adjust the playback progress, so as to locate the failure and analyze the cause of the failure.

3. Running statistics function Running time, operating time, operating efficiency, wire rope distance, number of handle actions, number of failures, failure time, failure rate and other port crane operating data are real-time statistics.

4. WEB release function Realize the picture release and data release of port crane operating information. System administrators or business leaders can remotely view the operating information of each equipment through the Internet to achieve remote monitoring and remote management. Through the network, you can get the same picture and data display, report display, alarm display, and trend curve display as on the WEB server anywhere.

5. Communication with the control center The real-time status data, real-time alarm, historical query, and equipment diagnosis data of the port crane safety monitoring system can communicate with the control center in real time, and the ground control center can understand the status of the field equipment in real time.

6. The system complies with the corresponding national standards and relevant industry standards.

5. Program summary

The system effectively improves the safety management level of large port cranes, reduces the workload of on-site maintenance staff, improves work efficiency, reduces equipment failure rate, and improves enterprise production efficiency.
