Description
Technical field
The present invention relates to crane crook of the arm field of measuring technique, specially a kind of crane large arm side sway detection method.
Background technology
For the fixed lift heavy equipment of crane or some other one end, when crane arm is when hanging load, due to manufacture and
Rigging error, the various factors such as side wind load, can cause large arm that side sway occurs in the horizontal direction, to influence the lifting of crane
Performance, when being more than nominal offset amount, it will forbid to operate, or even serious safety accident can occur, therefore how accurately to examine
The position for surveying crane large arm, to ensureing that the safety of operating environment has great significance.
Invention content
The problem of for background technology, the present invention provides a kind of crane large arm side sway detection methods.
To achieve the above object, the present invention provides the following technical solutions：A kind of crane large arm side sway detection method, including
Following steps：
S10：Base station is set up in crane vicinity；
S20：Satellite positioning receiving module is installed respectively with arm tail in the arm head of crane, for measuring arm head and arm tail
Location information is equipped with angle of revolution sensor on crane large arm turntable；
S30：The location information of arm head and arm tail that two satellite positioning receiving modules measure is sent to base station；
S40：The carrier phase signal of acquisition is sent to receiver user by base station, carries out asking poor by receiver user
Coordinate is resolved, obtains the precise positioning of crane arm head and arm tail in real time.
As a kind of preferred technical solution of the present invention, the satellite positioning receiving module for being set to arm tail is crane rotation
Center to the intersection point position of large arm.
As a kind of preferred technical solution of the present invention, base station is arranged in crane vicinity void spaces.
Compared with prior art, the beneficial effects of the invention are as follows：Tilly global position system of the present invention, to the position of large arm
It sets and measures, then by comparing the size that side sway is calculated and direction, this method utilizes RTK and GPS technology, detection essence
Degree securely and reliably can effectively measure large arm side sway up to Centimeter Level, ensure the safety of rectification system work.
Description of the drawings
Fig. 1 is flowage structure figure of the present invention；
Fig. 2 is present system structure pictorial diagram；
Fig. 3 is boom position detection principle diagram of the present invention；
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment：
It please refers to Fig.1 and Fig. 2, the present invention provides a kind of crane large arm side sway detection method, include the following steps：
S10：Base station is set up in crane vicinity；
S20：Satellite positioning receiving module is installed respectively with arm tail in the arm head of crane, for measuring arm head and arm tail
Location information, the optimal point of satellite positioning receiving module for being set to arm tail are crane rotation center to the intersection point position of large arm
It sets, angle of revolution sensor is installed on crane large arm turntable；
S30：The location information of arm head and arm tail that two satellite positioning receiving modules measure is sent to base station；
S40：The carrier phase signal of acquisition is sent to receiver user by base station, carries out asking poor by receiver user
Coordinate is resolved, obtains the precise positioning of crane arm head and arm tail in real time, specific steps are as follows：
1, (as shown in Figure 3) takes plane on the basis of ground level, projects to ground by the three-dimensional coordinate of crane arm head and arm tail
In plane, two points are obtained, 2 points of L0 in alignment are connected, using the position before work as datum line；
2, when crane works, in conjunction with the value of angle of revolution sensor 1, the position L1 of line after revolution is calculated；
3, the projection join line according to practical 2 points of position on ground level is L1 ', and arm head point is to the distance d of straight line L1
The as distance of large arm side sway, computing function all carry out in receiver user 5；
Signal interferes during transmission in order to prevent, and base station is arranged in crane vicinity void spaces.
Based on above-mentioned, present invention has the advantage that：Tilly global position system of the present invention, to the position of large arm into
Row measures, and then by comparing the size that side sway is calculated and direction, this method utilizes RTK and GPS technology, and accuracy of detection can
Up to Centimeter Level, securely and reliably, effectively large arm side sway can be measured, ensure the safety of rectification system work.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
