According to embodiments of the present invention, there is provided a kind of control method embodiment for being used to switch controller redundant signals, need
It is noted that can be in the computer system of such as one group computer executable instructions the flow of accompanying drawing illustrates the step of
Middle execution, although also, show logical order in flow charts, in some cases, can be with different from herein
Order performs shown or described step.
Fig. 1 is a kind of control method flow chart for being used to switch controller redundant signals according to embodiments of the present invention, such as
Shown in Fig. 1, this method comprises the following steps：
Step S102, obtains the first potentiometric first voltage value on controller, and on controller it is second potentiometric
Second voltage value.
As a kind of optional example, the controller in the application above-mentioned steps can be any one vehicle (including but
Be not limited to subway, light rail etc.) on for driver operation to control the master control electrical apparatus that vehicle is run, the controller can use two electricity
Position meter, two potentiometers may be incorporated for the gear positions information of collection vehicle, when driver is by pulling control handle in difference
Control gear when, above-mentioned potentiometer can produce different magnitudes of voltage as vehicle control signal.Using the department of dual potentineter
Control device, it is possible to achieve the switching of redundant signals, when a potentiometer failure causes the magnitude of voltage inaccuracy of output, can switch
For another normal potentiometer.In order to further determine that controller should control vehicle using which potentiometric magnitude of voltage
