Collision early warning system

Abstract

The invention discloses a collision early warning system. According to the system, at least two relatively independent devices or fixed collision bodies serve as collision main bodies, each collisionmain body comprises a data acquisition unit, a data processing unit, a data distribution unit, a collision calculation unit, a control output unit and a data display unit, the first collision main body carried out signal processing on the data acquired by the data acquisition unit so as to obtain the three-dimensional dynamic models of the whole devices and transmits the data to other collision main bodies at the same time, the other collision main bodies transmit the three-dimensional dynamic data to the first collision main body in the same manner, the actual distance between two collision main bodies are calculated through comparison, and the calculation result is fed back to a user through the data display units. The system has the advantages that the collision distance between the multiple devices can be calculated, the multiple devices can be controlled to take effective protection measures and provide alarm notification information according to calculation, and therefore the safety is high.

[0002] The anti-collision technology of hoisting machinery has always been available, but the current application is relatively simple and the application limitations are very large. The common application is like the anti-collision between two equipment on the track, which is generally realized by laser limit. When two When the distance between the equipment is less than a certain distance, the limit action is triggered, and the protection program is started to stop approaching each other; this method is only applicable to the situation where there is no spatial intersection between the equipment in the work area, such as two gantry cranes on the track can adopt this scheme; In addition, the area anti-collision technology is mostly used now. The regular graphic area of ​​​​the fixed position is detected through multiple limits. Once the equipment is included in the area, the protection program is activated to prevent the equipment from entering the area. This solution is more common in factory bridge machines. , mainly to prevent the bridge crane from colliding with the factory equipment during the operation; a little more complicated is the anti-collision system of the tower crane. The position and state information of other equipment can be detected through data exchange, so as to detect their respective distances for protection. However, the operation form of the tower crane is relatively simple, mainly because the rotation and lifting are changing in real time, and the position of the whole machine and the length of the boom are changed from The equipment has been fixed since the day it was installed, and the work is basically in a flat area. However, the collision problem cannot be solved well for gantry cranes and portal cranes, let alone the relationship between portal cranes and portal cranes. The reasons for the anti-collision problem are as follows: 1. Both seated cranes and gantry cranes are equipment with changing positions, unlike tower cranes whose positions do not change from the day they are built, so tower cranes are generally based on site drawings. Tower crane equipment establishes fixed spatial coordinates, while portal cranes and gantry cranes change their positions along the travel track, so we need to detect their walking positions and coordinates dynamically; 2. Portal cranes and gantry cranes are generally found in shipyards, site environment It is complex, which is not conducive to the establishment of data exchange channels between equipment. Tower crane equipment is generally found on construction sites, where the site is open, with little interference and no shelter; The mechanism increases the complexity of the space. Generally, the collision problem between the gantry crane and the gantry crane is that the gantry crane is located inside the gantry crane, so the collision situation is complicated. Common collision situations: (1) the big arm of the gantry crane collides with the rigid leg of the gantry crane; (2) ) The gantry machine collides with the main beam of the gantry crane; (3) The gantry machine collides with the flexible legs of the gantry crane

Its complexity is not the same as tower crane anti-collision
