Guidance system with photoelectric laser target

Abstract

The invention provides a guidance system with a photoelectric laser target. The guidance system comprises a photoelectric laser target for receiving laser signals, an analysis unit for converting photoelectric signals into coordinate signals of laser points, a communication unit for integrating, defining and transmitting the coordinate signals to an operation platform, and a laser theodolite for determining a guidance middle line and emitting red laser. The guidance system provided by the invention has the beneficial effects that the problems that the traditional guidance system has poor signals, has errors in pure artificial observation and can not extract measurement data can be effectively solved, meanwhile the cost is not high and the effect is excellent.

Description

technical field [0001] The invention relates to the field of pipe jacking construction of municipal pipelines, in particular to a guide system in a pipe jacking machine. Background technique [0002] At present, my country's urban pipe network construction is in full swing. Traditional pipe network reconstruction and construction require the road to be dug again, which not only causes economic waste, but also affects traffic and pollutes the environment. Compared with traditional construction methods, the pipe jacking method The construction has the advantages of no need to excavate the ground, small footprint, small traffic impact, fast excavation speed, environmental protection, economy, and high efficiency, and has been fully promoted and applied. [0003] The guide system is one of the most important systems of the pipe jacking machine, and it is a necessary condition to ensure the quality of the pipe jacking project. The traditional guide system of the pipe jacking machi...

[0003] The guide system is one of the most important systems of the pipe jacking machine, and it is a necessary condition to ensure the quality of the pipe jacking project. The traditional guide system of the pipe jacking machine is to place a laser target with a scale in the pipe jacking machine. Put a laser theodolite into the pit, measure and verify its elevation, and the position of the center line, and at the same time shoot a laser light on the laser target in the pipe jacking machine, install a camera at the rear end of the laser target, facing the laser target, At the same time, the picture is transmitted to the display screen of the console, and the operator of the pipe jacking machine can judge the up, down, left, and right deviations of the pipe jacking machine relative to the center line according to the relative displacement of the laser point on the laser target, and at the same time start the deviation correction device to correct the pipe jacking machine. The axis is corrected until the pipe laying work is completed. However, this method can only rely on the human eye to judge the deviation, and there are errors. The video signal is usually interfered by electromagnetic interference, resulting in snowflakes on the screen, or there is no signal, and the data cannot be stored.
