Magnetic stripe guidance is commonly used is also the lowest cost way, but the site setup has certain limitations, on the site decoration style has a certain impact.

Laser guide the highest cost of the site requirements are also higher, so generally not used.

RFID guidance costs moderate, the advantages of its guidance is high precision, site set up more convenient to meet the most complex site layout, the overall decoration of the premises without impact on the environment. Secondly, RFID's high security, stability is also magnetic stripe navigation and laser navigation does not have.

Electromagnetic induction: that is, our most common magnetic stripe navigation. It is through the adhesive magnetic tape on the ground, AGV automatic transfer vehicle passes through, the bottom of the car is equipped with electromagnetic sensors, will be sensed on the ground magnetic stripe landmarks, so as to realize the automatic driving transportation of goods. The site definition depends on the different combinations of magnetic stripe polarity.

Laser Induction: The laser scanner recognizes a number of fixed markers set in its activity range to determine its coordinate position, so as to guide the AGV to run.

RFID Induction: Through RFID tags and reading equipment to automatically detect the coordinate position, to realize the automatic operation of AGV carts, site definition through the arbitrary definition of the chip tags, even the most complex site setup can also be easily completed.

Advantages

With the gradual development of factory automation, computer-integrated manufacturing system technology, as well as flexible manufacturing systems, automated three-dimensional warehouses are widely used, AGV as a necessary means to link and regulate the discrete logistics management system and make its operation continuous, its application range and technology level has been rapid development.

The following are the advantages of AGV.

1. High degree of automation - controlled by computers, electronic control equipment, magnetic induction SENSOR, laser reflector and so on.

When a certain part of the workshop needs auxiliary materials, by the staff to the computer terminal to enter the relevant information, the computer terminal and then send the information to the central control room, by professional technicians to the computer to send instructions, in the cooperation of the electronic control equipment, this instruction is ultimately accepted by the AGV and implementation - auxiliary materials will be sent to the appropriate location.

2. Charging automation - when the AGV car's power is about to run out, it will send a request instruction to the system, requesting charging (generally technicians will set up a value in advance), in the system allowed to automatically go to the charging place "queuing" charging.

In addition, the battery life of AGV trolley is very long (more than 2 years), and every 15 minutes of charging can work for about 4h.

3. Aesthetics - to improve the degree of appreciation, thereby improving the image of the enterprise.

4. Safety - human driven vehicles, its traveling path can not be known. The AGV's guide path is very clear, so it greatly improves safety.

5. Cost control - AGV system capital investment is short-term, while the wages of employees is long-term, and will continue to increase with inflation.

6. Easy maintenance - infrared sensors and mechanical collision avoidance ensure that AGVs are protected from collisions and reduce failure rates.

7. Predictability - AGV will automatically stop when it encounters an obstacle on the driving path, while human-driven vehicles may have biased judgment due to human thought factors.

8. Reduction of product damage - it can reduce the damage of goods caused by the irregular operation of manual labor.

9. Improve logistics management - due to the intrinsic intelligent control of the AGV system, it can make the placement of goods more orderly and the workshop more tidy.

10. Smaller site requirements - AGVs require much narrower aisle widths than traditional forklifts. At the same time, for free traveling AGVs, it is also able to accurately load and unload goods from conveyors and other mobile equipment.

11. Flexibility - AGV systems allow for maximum changes in path planning.

12. Scheduling Capability - The reliability of the AGV system allows for a very optimized scheduling capability.

13. Process flow - AGV systems should and must be part of the process flow, it is the link that connects the many processes together.

14. Long-distance transportation - AGV systems can effectively carry out point-to-point transportation, especially suitable for long-distance transportation (greater than 60 meters).

15. Special working environment - Specialized systems can work in environments that are not easily accessible to personnel.
