The utility model discloses a device for realizing synchronization by using a laser rangefinder, which comprises a first car and a second car, the first and second cars are respectively arranged in two parallel orbits and running on the orbits, the first car is provided with a laser ranging device and a signal processing device connected with the laser ranging device, the signal processing device is connected with a car control device, the second car is provided with laser reflection boards, the distances between the laser reflection boards and the first car are different, and the running of the first and second cars is controlled by the car control device. The synchronization of engineering machines is controlled by using the device disclosed by the utility model; the device has the characteristics of simple structure, low cost and reliable implementation; and the device can be promoted and applied to the synchronization control of machines in other fields.
Description
Technical field
The utility model belongs to sync control device, is specifically related to a kind of laser rangefinder that utilizes and realizes synchronous device.
Background technology
At present, known common locate mode has GPS location, Direct Laser range finding location, total powerstation location etc.The GPS accuracy of positioning is not high, and the time is long, and expense is high; Laser rangefinder directly reads apart from length value and locates, although the laser rangefinder survey frequency is high, locating speed is fast continuously, but this method is with now most of laser rangefinder equipment, survey precision is lower than 500mm when its maximum measuring distance, do not accomplish accurate location, and most of laser rangefinder range of use can not surpass 500m; The total powerstation accuracy of positioning is high, but the frequency of reading out data is lower, can not satisfy continuous working.
The utility model content
The purpose of this utility model provides a kind of cheap, service-strong and utilizes laser rangefinder to realize synchronous device.
The technical scheme that its technical matters that solves the utility model adopts is:
The laser rangefinder that utilizes that the utility model provides is realized synchronous device, be included in first, second dolly that moves at each root track respectively in two parallel orbits, wherein be provided with laser ranging system and the signal processor unit that is connected with laser ranging system at the first dolly, signal processor unit is connected with car controller, be provided with laser reflection plate with the first dolly different distance at the second dolly, the operation of first, second dolly is controlled by car controller.
In the technique scheme:
Described laser reflection plate is three that front and back arrange;
Described signal processor unit is that wireless signal transmitting device is connected with car controller by wireless transmission method.
The laser rangefinder that utilizes that the utility model provides is realized synchronous device, simple and reliable, because measuring distance is little, therefore be subjected to weather effect less, can as being worth as a comparison with direct range finding, some synchronisation control meanss not affected by survey precision yet, more can not lose synchro control because of exceeding measurement range, be not subjected to the impact of track length yet, precision is constant, more can the elevator machinery operating range do not cross far away and lost efficacy, can be used for dolly synchro control on 2 tracks of construction machinery and equipment such as hoisting and hanging bridge machine, double track gantry crane of engineering.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Accompanying drawing is the structural representation of the utility model device.
Specific embodiments
As shown in drawings, the laser rangefinder that utilizes of the present utility model is realized synchronous device, the first dolly 4 and the second dolly 5 that comprise two parallel orbits 6,12, on track 6,12, move respectively, wherein be provided with laser rangefinder (laser sensor) 7 and the signal processor unit 11 that is connected with laser rangefinder 7 at the first dolly 4, signal processor unit 11 adopts the micro controller system computer, and signal processor unit 11 is connected with car controller control 11 by wireless signal transmitting device 10; Be provided with three blocks of laser reflection plates 1 in front and back, 2,3 in the second dolly 5 inboards, 3 blocks of laser reflection plates and laser rangefinder 7 distances are different, middle laser reflection plate 2 differs 400mm with the laser reflection plate 1 of front, differ 200mm with the laser reflection plate 3 of back, the length of laser reflection plate 2 is 100mm, and the operation of the first dolly 4 and the second dolly 5 is by car controller 13 controls.
When the first dolly 4 and the second dolly 5 travel basic synchronization (front and back are more or less the same in 100mm), laser rangefinder 7 Emission Lasers bundles 8 are penetrated on laser reflection plate 2, after laser reflection signal 9 is received by laser rangefinder 7, draw distance value 22600mm, sending signal processor unit 11 to analyzes, draw the analysis result of " normally ", car controller 13 is not taked any measure.When the second dolly 5 lags behind the amount of the first dolly 4 during greater than 100mm, the laser beam 8 of emission is penetrated on laser reflection plate 1, after laser reflection signal 9 is received by laser rangefinder 7, draw distance value 23000mm, sending signal processor unit 11 to analyzes, draw the analysis result of the second dolly 5 hysteresis the first dolly 4, then send the signal of the second dolly 5 acceleration to car controller 13 execution by wireless signal transmitting device 10.The amount that surpasses the first dolly 4 when the second dolly 5 is during greater than 100mm, the laser beam 8 of emission is penetrated on laser reflection plate 3, after laser reflection signal 9 is received by laser rangefinder 7, draw distance value 22800m, sending signal processor unit 11 to analyzes, draw the analysis result that the second dolly 5 surpasses the first dolly 4, then send the signal of the second dolly 5 decelerations to car controller 13 execution by wireless signal transmitting device 10.Laser beam 8 such as emission misses the target, and does not penetrate on any 3 blocks of laser reflection plates, and take off data is unusual so, and signal processor unit 11 analyzes unusual result, sends the instruction of sudden stop to car controller 13.
The selection of two dolly synchronization accuracies can be by adopting laser reflection plate 2 easy to do the reaching of different length.
