Security equipment can be divided into fixed equipment and mobile equipment. Fixed equipment usually constitutes so-called system-level components. Including the block system and equipment layout. Mobile devices, including vehicles, must follow a series of rules, such as load, center of gravity, speed and so on. Before using AGV system, users must be trained in using security system.
There are many kinds of traffic control and collision avoidance systems. The simplest thing is to install anti-collision bumper strips in front of the vehicle to keep the speed below a certain value. Once hit, the vehicle will stop until the resistance disappears. The other is area blockade, which separates different areas on the guide rail, and vehicles can only enter the next area without cars. The vehicle sensor is detected by the grounding loop under the guide rail. This method usually uses programmable controller to realize related logic control. More advanced is computer area blockade, which is similar to the principle of area blockade, but more complicated. The computer monitors the positions of all vehicles and the gaps between vehicles.
The layout of the workshop should consider the width of the vehicle passage, the distance from the pedestrian passage, the distance from the equipment to the workshop and so on. The detection of vehicles should include speed detection and load detection, in addition, to prevent personal injury. Relevant optical sensors and ultrasonic sensors can be used to detect the distance between vehicles.
With the improvement of people's requirements for production efficiency, the demand for AGV is increasing, and the technology of AGV will be more and more widely used.
