Description
Technical Field
The invention relates to the field of data retrieval, in particular to a balanced triangular support data search platform and a method.
Background
The data retrieval includes two operations of data sorting and data screening. The precondition for retrieval is that the data is sorted (assuming ascending order).
The binary search is to take numbers according to the binary principle to compare keywords, and the specific process is as follows: comparing the number of the middle position of the array with the keyword, and if the number of the middle position of the array is equal to the keyword, the retrieval is successful; if the number of the selected data is larger than the keyword, the next binary search ranges from the starting point of the data area to the current number of the selected data; if the number of the scores is smaller than the keyword, the range of next binary search is from the number of the scores to the end point of the data area. And the search range is gradually reduced by analogy until the end.
Disclosure of Invention
In order to solve the technical problems in the related field, the invention provides a triangular support data search platform for balance, which can search whether a tower crane is in a horizontal balance state on site or not according to the shape corresponding to a triangular support formed by a tower top, a crane boom and a balance arm, so as to correspondingly determine whether the tower crane is in the horizontal balance state or not.
Therefore, the invention needs to have the following two key points:
(1) detecting a triangular support which stabilizes the overall balance of the tower crane in the horizontal direction by adopting a customized detection mechanism so as to confirm a horizontal balance state when a triangular shape corresponding to the triangular support is detected, and otherwise, confirming a horizontal unbalance state;
(2) and storing a triangular shape corresponding to the triangular support in advance for subsequent detection, wherein the triangular shape is a shape corresponding to the triangular support formed by the tower top, the crane boom and the balance arm in a horizontal balance state.
According to an aspect of the present invention, there is provided a triangulated data search platform for balancing, the platform comprising:
the tower top is positioned on the tower crane and comprises a tower cap, and the tower top is connected to a crane boom and a balance arm through a pull rod on the tower cap to form a triangular support for stabilizing the overall balance of the tower crane in the horizontal direction;
the tower cap is connected with the tower body and connected with the slewing bearing to keep the balance of the whole tower body, and excessive twisting force cannot be generated in steering;
the real-time imaging mechanism is arranged opposite to the tower top and is used for performing real-time imaging operation on the periphery of the tower top so as to obtain a corresponding image around the tower top;
the point image restoration device is connected with the instant imaging mechanism and used for executing point image restoration processing on the received image around the tower top so as to obtain a corresponding point image restoration image;
the rotation correction device is connected with the point image restoration device and used for executing rotation correction processing on the received point image restoration image to obtain a corresponding rotation correction image;
an edge enhancement device connected to the rotation correction device for performing an edge enhancement process on the received rotation-corrected image to obtain an edge-enhanced image;
the shape detection device is connected with the edge enhancement device and used for receiving the edge enhancement image, searching a triangular shape corresponding to the triangular support in the edge enhancement image and sending a horizontal balance command when the search is successful;
wherein the shape detection device is further configured to issue a horizontal tilt command when a triangular shape corresponding to the triangular support is not searched in the edge-enhanced image;
the shape detection device further comprises a built-in storage unit, wherein the built-in storage unit is used for storing triangular shapes corresponding to the triangular supports in advance;
wherein the point image restoration device, the rotation correction device, the edge enhancement device, and the shape detection device are disposed opposite to the tower top.
According to another aspect of the present invention, there is also provided a method for searching for balanced triangular support data, the method comprising using the triangular support data search platform for balancing as described above to search for a shape corresponding to a triangular support formed by a tower top, a boom and a balance arm in a horizontal balanced state in real time.
The triangular support data search platform and the method for balancing are stable in operation and effective in identification. Because the existence analysis is carried out on the horizontal balance state of the tower crane by adopting an intelligent detection mechanism, the unbalance state of the tower crane can be found in time.
Detailed Description

An exemplary image inspection system comprises: the system comprises a light source, a lens, an industrial camera (comprising a CCD camera and a COMS camera), an image acquisition unit, image processing software, a monitor, a communication/input/output unit and the like.
At present, if the appearance of some parts of a tower crane is mismatched with the appearance of the parts in a normal operation state in operation, the tower crane is generally a sign of inclination or even unbalance of the tower crane, for example, the shape corresponding to a triangular support formed by the tower top, a crane arm and a balance arm in a horizontal balance state of the tower crane is fixed, however, a processing mechanism for analyzing the state of the tower crane by using the characteristics is not provided at present, and a feeling behind the inclination or even unbalance scene of the tower crane is known.

In addition, the shape detection device may be implemented using a generic array logic device GAL.
General Array Logic GAL (general Array Logic www.husoon.com) devices were the first electrically erasable, programmable, settable encryption bit PLDs invented by LATTICE. Representative GAL chips are GAL16V8, GAL20, which are capable of emulating almost all types of PAL devices. In practical application, GAL device has 100% compatibility to PAL device emulation, so GAL can almost completely replace PAL device, and can replace most SSI, MSI digital integrated circuit, thus obtaining wide application.
The biggest difference between GAL and PAL is that the output structure of the GAL is user-definable and is a programmable output structure. Two basic models of GAL, GAL16V8 (20 pins) GAL20V8 (24 pins), replace ten PAL devices, and are therefore called pain programmable circuits. The output of the PAL is well defined by the manufacturer, the chip is fixed after being selected, and the user can not change the chip.
