Large heavy-duty unmanned navigation intelligent electric flat carriage with automatic correction function

Abstract

The invention relates to a large heavy-duty unmanned navigation intelligent electric flat carriage with an automatic correction function. The electric flat carriage comprises a steel load carriage body, four drive wheels set which are arranged at the bottom of the load carriage body, a magnetic navigation sensor, an RFID reader, a power supply and a PLC control box, wherein the magnetic navigation sensor and the RFID reader are arranged on the axle wire of the bottom of the load carriage body, and the power supply and the PLC control box are arranged on the load carriage body. The magnetic navigation sensor and a navigation magnetic stripe laid on the ground of a production workshop are in magnetic induction connection. The RFID reader and a number of RFID electronic tags which are pasted on the navigation magnetic stripe with uniform spacing are in radio frequency communication connection. The magnetic navigation sensor comprises a number of Hall switch sensors, LED indication lamps corresponding to the Hall switch sensors and a control chip. The Hall switch sensors and the LED indication lamps are electrically connected with the control chip. The AGV trolley has the advantages of compact and reliable structure and heavy load, and realizes the functions of self-navigation and automatic correction at the same time through the magnetic navigation sensor.

Description

technical field [0001] The present invention relates to the technical field of unmanned transportation intelligent navigation trolley (ie AGV trolley), in particular to a large heavy-duty unmanned navigation intelligent electric flat trolley with automatic deviation correction function. Background technique [0002] Unmanned handling intelligent navigation car (Automated Guided Vehicle, AGV car) is a kind of battery as the power source, equipped with electromagnetic, optical or ultrasonic automatic guidance device, can drive along the specified guiding path, with parking selection device, safety Transport trolleys for protection systems and various mobile load functions. The AGV trolley has good adaptability and reliability, and can realize the integration and automation of production and handling functions. It has many advantages such as high transportation efficiency, good energy saving effect, reliable and stable work, flexible and variable use, and flexible transportatio...

AI Technical Summary

Problems solved by technology

In order to reduce the weight of the body as much as possible, the existing AGV trolley generally adopts a light-load structure, the load weight ranges from 50 kg to 20 tons, the transportation capacity is poor, the structure is complicated and the cost is high

In addition, the automatic deviation correction ability of the AGV trolley is poor, or even has no automatic deviation correction function, which requires manual real-time monitoring, which results in high labor costs and greatly affects production efficiency and economic benefits
