Specifically, it can be installed through, but not limited to, a pipe clamp. This installation position can ensure a wider field of view without blocking the line of sight, thereby improving safety.

[0028] In another specific embodiment of the above-mentioned distance measurement and monitoring early warning system for self-elevating platform placement, reference is made to Figure 4 , Figure 4 The figure is a schematic diagram of the composition of the laser radar-millimeter wave radar-camera integrated ranging submodule, with the front on the left and the back on the right. The laser radar-millimeter wave radar-camera integrated ranging submodule 22 includes a laser radar 221, a millimeter wave radar 222, a camera 223, a switching power supply 224 and a second switch 225.

The laser radar ranging submodule 21 may include a laser radar 211, a switching power supply 212 and a third switch 213, and the laser radar ranging submodule 21 may have a preset elevation angle of 30° to 60°, so that the ranging of protrusions in the vertical direction of the production platform can be carried out to avoid collision with the protrusions when the self-elevating platform is raised.

The wireless communication component is used to receive the wireless signal sent by the wireless communication base station, and after processing, it is displayed in real time on the ship-borne monitoring component. In this case, the drivers on the main tugboat and the auxiliary tugboat can synchronously obtain images, radars and alarm information, so that each can better ensure the safety of its operation. Further, the above-mentioned alarm component can be preferably an audible and visual alarm component, that is, it can use sound and light to alarm at the same time, so that it can give people warnings from the visual and auditory aspects of people at the same time, so that the timeliness of the warning is stronger, and people can know the warning information more quickly and deal with it in time, so as to better avoid the occurrence of collision.

[0031] The working process of the above-mentioned distance measurement and monitoring early warning system for the positioning of the self-elevating platform is as follows: the main and auxiliary tugboats cooperate to drag the self-elevating platform close to the production platform for positioning, and the three sets of distance measurement sub-modules perform distance measurement and visual imaging at the same time. The collected distance and image data are transmitted to the main control module through the optoelectronic composite cable. The data acquisition component on the main control module collects, stores and processes the collected data, and then displays it in real time on the monitoring display component to assist the positioning commander to complete the positioning; after the data acquisition component processes the data, it transmits it to the cockpit of the main and auxiliary tugboats through the communication base station at the same time, and displays it in real time on the ship-borne monitoring component, and sends out an audible and visual alarm to assist in reminding the tugboat driver to adjust the ship's status.

[0032] In summary, the above-mentioned ranging and monitoring warning system for the positioning of self-elevating platforms adopts multiple groups of high-precision ranging radars to measure the platform spacing. Compared with the previous ranging method in which operators use handheld laser rangefinders, it has the advantages of high ranging accuracy and high reliability. Moreover, the ranging and warning information are transmitted to the tugboat by base station transmission. Compared with the previous manual intercom method, the real-time information transmission is improved, so that the tugboat operator has enough time to adjust the ship's operation, thereby reducing the risk of collision caused by information transmission delays.
