Description

Technical Field

[0001] The invention relates to an armor system for an explosion-proof and dangerous operation AGV vehicle. Background Art

[0002] AGV has a history of 50 years since its invention. With the expansion of its application field, its types and forms have become diverse. AGV is often divided into the following types according to the navigation method during the automatic driving process of AGV: 1. Electromagnetic induction guided AGV. Electromagnetic induction guidance is generally to bury wires on the ground along a pre-set driving path. When a high-frequency current flows through the wire, an electromagnetic field is generated around the wire. Two electromagnetic sensors are installed symmetrically on the left and right of the AGV. The difference in the intensity of the electromagnetic signals they receive can reflect the degree to which the AGV deviates from the path. The automatic control system of the AGV controls the steering of the vehicle based on this deviation, and the continuous dynamic closed-loop control can ensure the stable automatic tracking of the set path by the AGV. This electromagnetic induction guided navigation method is currently used in most commercial AGVS, especially for large and medium-sized AGVs. 2. Laser guided AGV. This type of AGV is equipped with a rotatable laser scanner, and laser positioning marks with highly reflective reflective plates are installed on the walls or pillars along the running path. The AGV relies on the laser scanner to emit laser beams, and then receives the laser beams reflected back by the surrounding positioning marks. The on-board computer calculates the current position of the vehicle and the direction of movement, and corrects the orientation by comparing it with the built-in digital map, thereby realizing automatic transportation. At present, the application of this type of AGV is becoming more and more common. And based on the same guidance principle, if the laser scanner is replaced with an infrared transmitter or an ultrasonic transmitter, the laser-guided AGV can be transformed into an infrared-guided AGV and an ultrasonic-guided AGV. In the military, other detection and disassembly equipment can be integrated based on the automatic driving of AGV, which can be used for battlefield mine clearance and position reconnaissance. The MINDER Recce being developed by the British military is a reconnaissance vehicle with the ability to detect, destroy and verify mines. In steel mills, AGVs are used to transport furnace materials, reducing the labor intensity of workers. In nuclear power plants and places where nuclear radiation is used for fresh-keeping and storage, AGVs are used to transport items to avoid dangerous radiation. In film and film warehouses, AGVs can accurately and reliably transport materials and semi-finished products in dark environments. Therefore, AGVs are expensive, so they need a related armor system to protect their frame. Summary of the invention
