Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1, be structural representation of the present invention, a kind of automation detection and control device of the electric hand handle for controlling column, comprises electric hand handle, PLC, alarm unit, display unit and proportion magnetic valve valve group;
The output of electric hand handle connects the input of PLC, and the output of PLC connects the control end of proportion magnetic valve valve group, and alarm unit and display unit communicate to connect PLC respectively; Described PLC is connected with the obliquity sensor on column;
Described proportion magnetic valve valve group is connected with the oil cylinder on column, controls oil cylinder and stretches, change column angle of inclination.
Described proportion magnetic valve valve group adopts M4 valve valve group.
Output three signals of electric hand handle 3: X-axis signal voltage, Y-axis signal voltage and enable signal, to PLC1, receive the XM3.5 of controller respectively, on XM3.7, XM3.3 port.PLC1, after controlling and calculating, exports four electric proportional valves in control ratio electromagnetic valve valve group with XM1.5, XM1.6, XM1.7, XM1.8 tetra-PWM electric currents, the action all around of the corresponding vertical mast oil cylinder of these four electric proportional valves difference.PLC1 is by signal voltage simultaneously, output current, and the data such as alarm signal and indicating fault send to display 4 by CAN, and display 4 shows, so that operating personnel can Timeliness coverage and process.
As shown in Figure 2, the operating principle of electric hand handle is: the motion that electric hand handle controls column is divided into X-direction and Y direction.
In fact electric hand handle is made up of two mutually perpendicular slide rheostats, according to the position of the swept resistance in each direction, provides corresponding signal voltage to utilize corresponding input voltage to decide the direction of motion and the speed of column to PLC, PLC.When meta, the signal voltage of X-axis and Y-axis is all the input analog amount signal that 2.5V, PLC receive X-axis end and Y-axis end is all that 16384, PLC thinks that electric hand handle is now at meta, does not export any action.When electric hand handle turns left motion from meta, electric hand handle X-axis output voltage is reduced to 0V from 2.5V, and the input signal correspondence that PLC receives from electric hand handle reduces to zero from 16384; Equally, when electric hand handle turns right motion from meta, voltage is increased to 5V from 2.5V, and the input signal that PLC receives from electric hand handle is increased to 32767 from 16384.Y direction is like this too.PLC exports the opening of PWM Current Control proportion magnetic valve according to the size of analog quantity, thus reaches the object controlling column motion.
And when electric hand handle goes wrong, if generation is short trouble, so the signal voltage of X-axis and Y-axis is certain to remain the highest 5V always, and controller can keep the input value of 32767 certainly always.As long as now electric hand handle one is enable, in any case operation electric hand handle, column all can be turned right or action forward.Same, if open circuit fault occurs, electric hand handle input voltage is minimum 0V certainly, so in any case operation electric hand handle, and column all can be turned left or backward.This situation is breakneck for the machine having column.
For problems of the prior art, the present invention proposes following method and carries out automatic detection and control to electric hand handle, a kind of automation detection and control method of the electric hand handle for controlling column, the automation detection and control device of the electric hand handle for controlling column described in employing, following detection and control is carried out to electric hand handle, comprises the following steps:
