An automatic charger navigation system and navigation method for unmanned electric vehicles

Abstract

An automatic charger navigation system for unmanned electric vehicles, including: laying tag cards at intervals on the charging parking space to establish a two-dimensional coordinate system; fixing a reader card at the four corners of the unmanned vehicle chassis The reader is used to read the position of the tag card. The charging hole is set at the diagonal intersection of the four card readers; the signal transmitting end on the unmanned vehicle and the signal receiving end on the charging car. The use of this navigation system simplifies the unmanned vehicle charging system and provides a feasible solution for the industrial development of automatic charging.

Description

technical field [0001] The invention belongs to the field of unmanned vehicle charging, and in particular relates to a low-cost navigation system for an automatic charger for unmanned electric vehicles. Background technique [0002] At present, most of the unmanned vehicles in the market are electric vehicles. The advantages of electric vehicles are easy to control, energy saving and environmental protection, simple structure and low noise. But there are also disadvantages, such as short battery life, high cost of batteries and motor controllers, the most important of which is the need for frequent charging due to fast power consumption, and the cost of currently built service stations is too high to be popularized. [0003] The existing charging piles and other similar charging facilities require manual operation, such as the charging of unmanned vehicles requires human assistance, which is not smart enough and inconvenient to operate. In the existing patents, the charging...

Problems solved by technology

But there are also disadvantages, such as short battery life, high cost of batteries and motor controllers, the most important of which is that the power consumption is fast and frequent charging is required, and the service stations currently built are too expensive to be popularized

[0003] Existing charging piles and other similar charging facilities require manual operation, such as unmanned vehicle charging requires human assistance, which is not smart enough and inconvenient to operate

The structure of the charging device in the existing patents is complex, the equipment and facilities are expensive, and it is not conducive to the popularization of unmanned vehicle charging facilities, and the navigation method of the automatic charging machine is unreliable, and it is prone to signal transmission interference, misinformation, and leakage.
