Wireless control locomotive electric windshield wiper control device

Abstract

The invention discloses a wireless control locomotive electric windshield wiper control device which comprises a switch box and a windshield wiper controller; a switch box microcontroller circuit transmits wireless control commands of stop, low speed, high speed and intermittence to a wireless receiving circuit of the windshield wiper controller through a wireless transmission circuit according to an input signal of a key circuit, a windshield wiper microcontroller circuit changes the duty ratio of an outputted pulse width modulation signal according to the received wireless control commands, and a windshield wiper motor control circuit controls a windshield wiper motor to implement the motions of stop, low speed, high speed and intermittence. The switch box does not need to be connected with the windshield wiper controller through an electric wire, is controlled directly through a wireless signal, and is convenient to install; the switch box does not need to be placed at an installing position specially designed in advance in a driver control room, and can be directly placed at a position convenient for the operation of a driver, and the operation is convenient; and besides, the potential safety hazard of driving, caused by the fact that the driver bends down to operate the switch box, is reduced.

Description

technical field [0001] The invention relates to the electronic technical field of a wirelessly controlled electric wiper control device for locomotives, and is especially suitable for wipers used in rail traffic such as locomotives, urban rails, and subways. Background technique [0002] The current locomotive electric wiper control device includes two parts: a switch box and a wiper controller. The switch box and the wiper controller are connected through a cable, which is inconvenient to install; When installing the wiper control device, the installation position of the switch box must be specially designed in advance on the locomotive, otherwise it cannot be installed; at the same time, the switch box is generally designed to be installed in a secondary position in the driver's control room, and it is often necessary to bend down to control it , affecting the normal driving operation of locomotive drivers, causing hidden dangers in driving safety.
