Automated Guided Vehicle, abbreviated as AGV, also commonly known as AGV trolley, refers to a transport vehicle equipped with electromagnetic or optical automatic navigation devices, which can drive along the specified navigation path, and has safety protection and various transfer functions. Due to its strong flexibility and high degree of intelligence, it has a wide range of applications and market prospects in China.
In order to protect people and objects from damage, AGVs need reliable protection. Accordingly, the relevant safety standard for AGV vehicles and systems has been formulated internationally - ISO 3691-4 (safety requirements and verification of unmanned industrial vehicles and their systems). The safety laser scanner PSENscan from Pilz detects objects in the path of a vehicle and provides safety even at high speeds without compromising productivity.
In the PSENscan product group, the PSENsc ME 5.5 08-17 model is particularly suitable for AGV applications. This is because in addition to the area detection function, this model can also integrate an encoder input. After connecting the encoder, the scanner can obtain the current speed of the trolley, and judge whether the trolley exceeds the maximum speed, and determine whether the trolley is driving at a safe speed, saving the user the effort of writing a program to evaluate the speed of the trolley. PSENscan can be used in a master-slave configuration and can be protected from all sides thanks to two safety laser scanners mounted at the end of the AGV.
With the PSENscan safety scanner, the user can configure up to 70 protected areas and warning zones. It enables AGVs to ensure safe driving when cornering in complex environments. Switch to a suitable protected area and warning zone via the safety controller to suit the current driving path.
In addition to the safety personnel detection function, PSENscan also measures the distance to objects in the environment and therefore supports AGV SLAM navigation, thus opening up new opportunities for production logistics. With the ROS (Robot Operating System) software package, users can easily integrate multiple safety laser scanners into their existing ROS environment without any additional programming. In addition, Pilz offers the C++ package PSENscan, which allows users to integrate into their own navigation systems.

Peel magnetic relays - what are the connection methods of relays?
1. 3-pin relay wiring
The common 3-pin relay is the car horn relay.
No. 1 is the contact terminal, which connects the load;
No. 2 is the common terminal between the contact and the coil, which is connected to the power supply;
No. 3 is the coil terminal, which connects the button switch (such as the horn on the steering wheel).

Peel magnetic relay - relay common faults and solutions
First, the contact is loose and cracks
The contact is the electrical touch part of the relay to complete the switching load, and the contact of some products is riveted and pressed, and its primary disadvantage is that the contact is loose, the contact cracking or the scale azimuth error is too large. This will affect the touch reliability of the relay.
