Problems solved by technology

[0004] One of the main problems of unmanned driving is the positioning of the body in the coal yard. Traditional GPS positioning is more suitable for outdoor scenes. When it is used in indoor coal yards, the signal is easily blocked by obstacles such as buildings, and it is in a state of motion. GPS is often difficult to locate, and the existing indoor positioning methods such as Wi-Fi positioning, Bluetooth positioning, and radio frequency positioning also have problems such as low accuracy and short positioning distance. It is necessary to apply a new method in the coal yard to overcome the current question

Abstract

The invention discloses a pure electric drive unmanned coal pusher. The pure electric drive unmanned coal pusher is used for carrying out stacking work of coal in a coal yard, a UWB positioning module, a UWB positioning base station and a central control room control system are mounted in the coal yard, the pure electric drive unmanned coal pusher comprises an unmanned coal pusher body, an angle sensor, a UWB positioning label, a laser module detection device, a monitoring camera and an ultrasonic radar, the unmanned coal pusher body is provided with a motor driving system, the efficiency of atransmission system is improved, noise generated during running is reduced, due to the variable frequency function, adjustment of motor rotating speed is convenient, a transmission with the giant size is reduced, precise control over the coal pusher speed and power can be achieved, the technical foundation is provided for unmanned driving of the coal pusher, and the unmanned driving safety and reliability can be effectively improved.

Description

technical field [0001] The invention relates to a coal pusher, in particular to a pure electric drive driverless coal pusher. Background technique [0002] The coal yards of enterprises generally use coal pushers as auxiliary machinery for coal stacking operations. The coal pushers basically use diesel engines. Enterprise diesel is managed as dangerous goods, which increases the difficulty of enterprise management, and the maintenance of diesel engines is very troublesome. . In addition, because the engine is affected by the running time, it must be overhauled or replaced. At the same time, burning diesel as power is not environmentally friendly. Changing the drive from a diesel engine to an electric motor will not only facilitate the use and maintenance of the coal pusher, but also allow the coal pusher The operation of the machine is more environmentally friendly, which will be the development direction of the coal pusher in the future. [0003] In terms of operation, th...
