Problems solved by technology

However, there have been many times in practical applications. When the magnetic sensor fails, especially when there is no magnetic signal but the electromagnetic conversion part still outputs electrical signals, the magnetic sensor will induce the AGV to continue driving to the area where the guidance signal is not set, resulting in the AGV and its load. equipment damage

Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0019] The magnetic sensor fault alarm device I described in the present invention is installed on the magnetic sensor II, and is composed of a voltage comparator 11 and a fault alarm device 12. The magnetic sensor II includes an electromagnetic conversion part 13 and an output drive part 14, and the output drive part 14 can drive the AGV. The controller 15 outputs an electric signal.

[0020] The working principle of the fault alarm is that the voltage comparator 11 on the fault alarm device I can sample the electrical signal "a" at A that the electromagnetic conversion part 13 on the magnetic sensor II outputs to the output drive part 14 and the output drive part 14 to the AGV drive control The electrical signal "b" at B output by the device 15, and compare the electrical si...

Abstract

The invention discloses a fault alarm device of magnetic sensor. The fault alarm device is mounted on the magnetic sensor, and consists of a voltage comparer and a fault alarm. The fault alarm device provided by the invention is mounted on the magnetic sensor so as to enable an AGV (automatic guided vehicle) to correct the mistake automatically after the AGV is misled to a wrong route, thereby preventing damages to the AGV and equipment on the AGV, and ensuring safe operation.

Description

technical field [0001] The invention belongs to the field of mechanical transportation, in particular to a magnetic sensor failure alarm device used on an AGV. Background technique [0002] In order to reduce labor costs and improve production efficiency, most factories have realized automated processing, and automated transportation can further improve corporate efficiency. However, transporting with a conveyor belt has the disadvantage of occupying a large area, so now there is a new type of automatic transfer vehicle (AGV) to complete the transport task in the factory. AGV uses pre-laid magnets to control the car’s walking route, detects the pre-set magnetic field route through the magnetic sensor, converts the magnetic field signal into an electrical signal, and then outputs the weak electrical signal through a series of amplifier circuits in the output drive part, etc., and outputs a signal that can The electric signal that drives the controller can guide the walking d...
