A kind of non-contact digital driver controller

Abstract

The invention discloses a non-contact digital driver controller, which comprises a rotation handle structure, a magnet, a position sensor chip and a main board, wherein the magnet is arranged on a rotation shaft and coaxially rotates along with the rotation shaft at the same angular velocity, the position sensor senses the rotation angle of the magnet, and CAN frame is encapsulated after the consistent output is confirmed by the microcontroller on the main board and is treated by a traction / braking system. According to the present invention, the structure of the rotation handle structure allows movements toward two directions so as to control the two directions such as locomotive advancing and locomotive retreating while the handle turning angle and the locomotive speed control are correlated through the position sensor and the main board, the non-contact sensing design is used, the starting torque is small, and the smoothness is high; and the single handle control and output is stepless, and the driving direction and the speed giving are integrated, such that the disadvantages of large volume, touch point wear, short service life, more maintenance, non-continuous output and the like of the old driver controller are overcome, and the r small, intelligent and reliable requirements of the new generation of the driver controller are met.

Description

technical field [0001] The invention relates to the technical field of locomotive control, in particular to a non-contact digital driver controller. Background technique [0002] The driver controller is the main electrical appliance that directly controls the driving of the rail engineering vehicle. Its main function is to judge the direction in which the driver pushes the handle or turns the handwheel through a certain type of sensor, and converts the corresponding angular displacement into an electrical signal and outputs it to the traction / Braking system to realize the start, stop and speed regulation of the locomotive. Since rail vehicle operations are mostly required to be completed within a certain operating window, there are high requirements for the reliability and life of the components. At the same time, the accuracy and efficiency of the operation also put forward relatively high requirements for the smoothness and output accuracy of the driver's controller. h...

However, because it can only output preset values ​​at the encoding place, and the amount of encoding is limited by the volume of the encoder, this type of encoder may be huge and occupy a lot of space on the console. Due to the limited encoding, the output accuracy is not high, for example : Patent No. CN200620052707, the use of non-contact magnetic pulse encoder avoids the core shortcomings of the contact driver controller, but due to the traditional double-handle design and the presence of encoders, its volume is still very large and limited by the number of codes , unable to achieve continuous output of stepless

[0004] In addition, most of the above two types of driver controllers do not have the bus communication function, and wiring needs to be set up separately between related controllers, resulting in many layout restrictions, high wiring costs, and low reliability, which is not conducive to the distribution of equipment. type control
