Problems solved by technology

The positioning accuracy of GPS is not high, and it takes a long time and the cost is high; the laser rangefinder directly reads the distance and length value for positioning. For rangefinder equipment, the measurement accuracy is lower than 500mm at its maximum measurement distance, and precise positioning cannot be achieved, and most laser rangefinders cannot use more than 500m; the total station has high positioning accuracy, but the frequency of reading data is low , cannot satisfy continuous operation

Embodiment Construction

[0013] specific implementation plan

[0014] As shown in the accompanying drawings, the device of the present invention that utilizes a laser range finder to realize synchronization includes two parallel tracks 6, 12, a first dolly 4 and a second dolly 5 that run respectively on the tracks 6, 12, wherein The trolley 4 is provided with a laser range finder (laser sensor) 7 and a signal processing device 11 connected with the laser range finder 7. The signal processing device 11 adopts a single-chip computer, and the signal processing device 11 is controlled by a wireless signal transmitter 10 and the dolly. The device control 11 is connected; three laser reflectors 1, 2, and 3 are arranged on the inside of the second trolley 5, and the distances between the three laser reflectors and the laser rangefinder 7 are different, and the laser reflector 2 in the middle is different from the front one. Laser reflector 1 differs by 400mm, and differs by 200mm from laser reflector 3 at th...

Abstract

The invention discloses a method and a device for realizing synchronization by using a laser distance meter. The method includes the steps: arranging a laser distance measuring device on a first trolley running along one rail of two parallel rails, arranging a laser reflector different from the first trolley in distance on a second trolley running along the other rail, using the laser distance measuring device to detect distance change signals reflected by the laser reflector when the two trolleys are asynchronous to cause change on distance between the same, and using a trolley controller to control running speed of one trolley to be kept synchronous with the other trolley after the signals are processed by a signal processing device. The method and the device for controlling synchronization of engineering machines have the advantages that the device is simple in structure, cost is low and execution is reliable, and can be popularized to be used for mechanical synchronization control in other fields.

Description

technical field [0001] The invention belongs to a synchronous control method and device, in particular to a method and device for realizing synchronization by using a laser range finder. Background technique [0002] At present, known common positioning methods include GPS positioning, direct laser ranging positioning, total station positioning, and the like. The positioning accuracy of GPS is not high, and it takes a long time and the cost is high; the laser rangefinder directly reads the distance and length value for positioning. For rangefinder equipment, the measurement accuracy is lower than 500mm at its maximum measurement distance, and precise positioning cannot be achieved, and most laser rangefinders cannot use more than 500m; the total station has high positioning accuracy, but the frequency of reading data is low , cannot satisfy continuous operation. Contents of the invention [0003] The object of the present invention is to provide a cheap and reliable meth...
