Description

Technical Field

[0001] This utility model relates to the field of offshore platform personnel boarding gangway technology, and in particular to a control system for offshore platform personnel boarding gangway. Background Technology

[0002] The connection between maritime transport vessels and offshore platforms relies on boarding gangways and gangways. Personnel on maritime transport vessels enter the offshore platform via boarding gangways fixed to it for work. To adapt to the vessel's position, the boarding gangways need to be adjusted and controlled during use. Existing technologies typically involve manual operation of offshore platform boarding gangways, resulting in low levels of automation. Furthermore, they lack the function of monitoring the load-bearing capacity of the boarding gangways. When the load on the boarding gangways is heavy, there is no warning or alert to personnel, which could lead to the boarding gangways sinking due to excessive weight, posing a safety hazard. In light of the above, this application proposes a control system for offshore platform boarding gangways. Utility Model Content

The PLC controller, data acquisition and processing module, and communication module are all installed in the monitoring room of the offshore platform 6.

The specific processing and analysis principles can be achieved by CNC programmers editing the corresponding control value programs, which are all conventional methods or common knowledge, and will not be elaborated here.

[0027] The first cumulative weighing platform 2 and the second cumulative weighing platform 5 are both used to cumulatively weigh the pedestrians. Both the first cumulative weighing platform 2 and the second cumulative weighing platform 5 are connected to the zeroing module. The first cumulative weighing platform 2, the second cumulative weighing platform 5, the second monitoring camera 8, the first monitoring camera 9, and the touch switch 10 are all connected to the data acquisition and processing module. The data acquisition and processing module is an analog-to-digital converter, which is used to acquire the signals output by the first cumulative weighing platform 2, the second cumulative weighing platform 5, the second monitoring camera 8, the first monitoring camera 9, and the touch switch 10, and convert the acquired signals into digital signals for transmission to the data transceiver module. The data acquisition and conversion principle of the analog-to-digital converter is existing technology and will not be described in detail here.

[0028] The intelligent algorithm module is used to calculate the weight of the first cumulative weighing platform 2 and the second cumulative weighing platform 5. The calculation formula is: the total weight of personnel weighed by the first cumulative weighing platform 2 - the total weight of personnel weighed by the second cumulative weighing platform 5 = the total weight of the remaining personnel on the boarding ladder 1. The load threshold setting module is used to set the maximum weight that the boarding ladder 1 can bear. The intelligent algorithm module is connected to the data transceiver module and the load threshold setting module.

[0029] The load warning and limiting mechanism includes two electric slide rails 7 fixedly connected to the top of the first cumulative weighing platform 2. The sliding ends of the two electric slide rails 7 are fixedly connected to the same limiting baffle 13. The bottom of the limiting baffle 13 is in active contact with the top of the first cumulative weighing platform 2.

The display screen 12 is used to display the weight that can be carried by personnel boarding the gangway 1 and the current weight carried.

[0030] The angle adjustment mechanism 4 includes a circumferential angle rotary motor and a tilt angle adjustment motor. Both the circumferential angle rotary motor and the tilt angle adjustment motor are connected to the control module. The circumferential angle rotary motor is used to adjust the circumferential angle of the personnel boarding ladder 1, and the tilt angle adjustment motor is used to adjust the tilt angle of the personnel boarding ladder 1. The mechanical drive adjustment principle is based on existing technology in the personnel boarding ladder 1, which will not be elaborated here. Through a series of structural settings, this utility model can intelligently adjust the personnel boarding ladder 1, improve the level of intelligence, effectively reduce the workload of operators, and effectively monitor the weight carried on the personnel boarding ladder 1. When the weight carried on the personnel boarding ladder 1 is too heavy, it can promptly remind personnel to stop entering, thereby improving safety during use.

[0031] Working principle: During use, the top position of the target vessel is higher than the position of the offshore platform 6. When adjusting the personnel boarding gangway 1 according to the position of the target vessel, personnel can power on the entire control device. When powered on, the two first monitoring cameras 9 monitor the position of the target vessel. The data acquisition and processing module collects the information monitored by the first monitoring cameras 9 and transmits it to the PLC controller. The PLC controller receives the information through the data transceiver module and analyzes the information through the data analysis module to determine the position of the target vessel. The control module then controls the circumferential angle rotation motor, the tilt angle adjustment motor, and the length adjustment motor. The control module controls the circumferential angle rotation motor. When the circumferential angle rotation motor is turned on, it drives the personnel boarding gangway 1 to rotate circumferentially. During the rotation of the personnel boarding gangway 1, the two first monitoring cameras 9 continuously monitor the position of the target vessel. When the monitoring camera 9 is found to be horizontally aligned with the target vessel, the control module controls the circumferential angle rotation motor to turn off. At the same time, the tilt angle adjustment motor adjusts the tilt angle of the personnel boarding gangway 1. The personnel boarding gangway 1 drives the second monitoring camera 8 to rotate through the first cumulative weighing platform 2. Simultaneously, the second monitoring camera 8 monitors the rotation position of the first cumulative weighing platform 2. The control module collects monitoring information through the data acquisition and processing module and transmits it to the data analysis module for analysis through the data transceiver module. When the analysis determines that the first cumulative weighing platform 2 is above or level with the top of the target vessel, the control module shuts off the tilt angle adjustment motor. Simultaneously, the length adjustment motor adjusts the length of the personnel boarding ladder 1. When the personnel boarding ladder 1, via the first cumulative weighing platform 2, moves the second monitoring camera 8 to the top of the target vessel, the control module can shut off the length adjustment motor. When the bottom of the first cumulative weighing platform 2 is not in contact with the top of the target vessel... Then the control module controls the tilt angle adjustment motor to turn on again, causing the personnel boarding gangway 1 to rotate the first cumulative weighing platform 2 again. The first cumulative weighing platform 2 drives the touch switch 10 to move to contact the top of the target ship, triggering the touch switch 10 to turn on. The touch switch 10 transmits the signal to the data analysis module through the data acquisition and processing module and the data transceiver module in sequence. After analysis, the data analysis module controls the tilt angle adjustment motor to turn off through the control module, thereby realizing the automatic adjustment of the personnel boarding gangway 1. By automatically adjusting, the level of intelligence is improved, which can effectively reduce the workload of the operators.

[0032] The total weight that the personnel boarding gangway 1 can bear can be preset through the load threshold setting module. After the personnel boarding gangway 1 is adjusted, the two electric slide rails 7 can be opened by the synchronous switch. The sliding end of the electric slide rail 7 drives the limiting baffle 13 to move upward to remove the obstruction on the top of the first cumulative weighing platform 2. At this time, personnel can enter the personnel boarding gangway 1 through the first cumulative weighing platform 2 and enter the offshore platform 6 through the second cumulative weighing platform 5. The first cumulative weighing platform 2 and the second cumulative weighing platform 5 weigh the weight of the personnel passing through. The weighed weight is collected by the data acquisition and processing module and transmitted to the intelligent algorithm module through the data transceiver module. The intelligent algorithm module uses the formula: "Total weight of personnel weighed by the first cumulative weighing platform 2 - Total weight of personnel weighed by the second cumulative weighing platform 5 = Remaining weight of personnel on the personnel boarding gangway 1". The formula "total weight of personnel" is used to calculate the current load-bearing weight on the boarding ramp 1. The calculated weight value is displayed on the display screen 12, allowing personnel to intuitively know the current load-bearing weight on the boarding ramp 1. If the current load-bearing weight on the boarding ramp 1 is the same as or slightly greater than the set threshold weight, the control module controls the audible and visual alarm 11 to be activated to remind personnel. At the same time, the synchronous control switch controls the two electric slide rails 7 to drive the limiting barrier 13 to move downwards to block the top of the first cumulative weighing platform 2, preventing personnel from continuing to enter the boarding ramp 1. Through alarm reminders and restrictions, personnel can be promptly reminded to stop entering when the load-bearing weight on the boarding ramp 1 is too heavy, thereby effectively reducing the possibility of the boarding ramp 1 sinking due to excessive load and improving safety during use.

[0033] As personnel continue to exit from the second cumulative weighing platform 5, the weight on the boarding ladder 1 gradually decreases. When the calculated weight on the boarding ladder 1 is zero, the zeroing module controls the first cumulative weighing platform 2 and the second cumulative weighing platform 5 to be zeroed, so that they can wait for the next weighing operation. At the same time, the control module can control the audible and visual alarm 11 to turn off, and control the two electric slide rails 7 to drive the restriction barrier 13 to move upward again to remove the barrier, so that personnel can continue to enter.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
