Novel omnidirectional wheel walking and anti-collision system

Abstract

The invention relates to a novel omnidirectional wheel walking and anti-collision system with high safety and capable of effectively improving working efficiency. The anti-collision system comprises an object motion information collecting unit, an object image volume information collecting unit, a collision information collecting unit, a safety protective unit and an alarm device which are arranged on the mobile platform; every AGV trolley can reach the identifying and control accuracy and rapidity according to the detected position of a barrier, so as to timely and actively avoid the barrier;when the ECU judges that a human body is collided, the system can pop up a safety bag to better protect the human body.

Description

technical field [0001] The invention relates to the technical field of AGV trolleys used in storage systems, in particular to a novel omnidirectional wheel walking and anti-collision system. Background technique [0002] In the automated storage system, the AGV trolley is the key equipment of the system. The existing AGV trolley (Automated Guided Vehicle, referred to as AGV), also known as unmanned van, refers to equipped with automatic guidance devices such as electromagnetic or optical, which can drive along the prescribed guiding path, and has safety protection and various transfers. Functional transport vehicle, a transport vehicle that does not require a driver in industrial applications, uses a rechargeable battery as its power source, and generally controls its travel route and behavior through a computer, or uses an electromagnetic path-following system to set up its For the traveling route, the electromagnetic track is pasted on the floor, and the unmanned van reli...

Problems solved by technology

[0005] In order to change the rotation direction of the four mecanum wheels at any time, the existing technology uses four motors to drive the four mecanum wheels respectively, that is, one motor corresponds to one mecanum wheel. In order to accurately control the movement of the platform, often The control requirements for the motors are very high, and the precision requirements for the speed and input power of the four motors are also very high, which makes the cost of the omnidirectional wheel walking system very high, and the motors also occupy a large space, making the system too large

[0006] At present, the AGV trolley with omnidirectional wheels is widely used due to its extremely small turning radius and flexible walking characteristics, while the AGV trolley with omnidirectional wheels can realize straight and horizontal travel. It becomes the front of the driving direction, and the traditional collision buffer mechanism can only realize protection in one direction. For the AGV trolley with omnidirectional wheels, it cannot meet the requirements of its safety protection. If you want to realize four directions when walking protection, the size and weight of the protective device are large, and the structure is complex, the number of parts is large, the cost is high, and it is difficult to maintain
