Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples
As shown in fig. 1 and 2, fig. 1 is an application scenario diagram of an insulation column cleaning and positioning system in the present embodiment, fig. 2 is a partial enlarged view of a portion a in fig. 1, in which a locomotive 100 is located at a station to be cleaned, a guide rail 200 and a cleaning arm 300 sliding on the guide rail 200 are disposed above both sides of the locomotive 100, and the cleaning arm 300 can achieve preliminary positioning by moving to a specific position along the guide rail 200 to correspond to an insulation column 110 on top of the locomotive 100.
By installing the proximity switch on the guide rail 200 and making the proximity switch correspond to the position of the insulation column 110, when the mount 301 of the cleaning arm 300 moves to the position corresponding to the proximity switch, the mount 301 is powered off and stopped, so that the cleaning arm 300 stays at the position corresponding to the insulation column 110.
Alternatively, the proximity switch in this embodiment needs to use an active proximity switch, such as an eddy current proximity switch, a hall proximity switch, or a photoelectric proximity switch. As shown in fig. 3, the proximity switch is selected as an eddy-current proximity switch, when the proximity switch is approached by using a conductive object to generate an electromagnetic field, eddy currents are generated in the object, the eddy currents react to the proximity switch, and the internal circuit parameters of the switch are changed, so that whether the conductive object moves closer or not is identified, and the on or off of the switch is controlled. The vortex proximity switch is mounted on a mounting seat 301, a plurality of positioners 302 are mounted at equal intervals along the length direction of the guide rail 200, the positioners 302 are conductors capable of being matched with the vortex proximity switch and capable of controlling on-off, the positioners 302 are controlled to be conducted (see a filling part in fig. 3), and when the mounting seat 301 moves to the conducted positioners 302, the positioners 302 enable vortex flow inside the vortex proximity switch to be generated when approaching the vortex proximity switch so as to realize on-off control. When the conducting positioners 302 are in one-to-one correspondence with the insulating columns 110, only the part of positioners 302 can generate vortex with the vortex type proximity switch and generate detection signals, and the detection signals are converted into driving signals for the mounting base 301, so that the mounting base 301 can be controlled to be stopped at a preset position to realize positioning.
Optionally, as shown in fig. 4, the insulation column cleaning positioning system of this embodiment further includes a positioning detection module 401, an adder 402, a PLC control module 403, and a power supply module 404, where the positioning detection module 401 is configured to detect a position of the locomotive 100, assist the locomotive 100 to stop positioning and output a detection signal, the adder 402 counts and adds a count of a signal to generate a value signal once each time the detection signal output by the positioning detection module 401 is received by the adder 402, a default value of the adder 402 is 0, the PLC control module 403 obtains the value signal to generate a control signal, and the power supply module 404 receives the control signal to control the positioner 302 to form an on-off state according to a specified arrangement.
When the locomotive 100 enters a cleaning area and the first carriage enters a designated position, the positioning detection module 401 detects that a feedback signal is sent to confirm that the first carriage enters the designated position, for example, feedback can be realized in an audible and visual alarm mode, so that the locomotive 100 is assisted in positioning, meanwhile, the positioning detection module 401 also generates a corresponding detection signal, and because the default value of the adder 402 is 0, when the detection signal of the first carriage enters the adder 402, the output numerical value signal of the first carriage becomes 1, and then the PLC control module 403 receives the numerical value signal 1 and executes a preset user program output control signal in the PLC control module 403, wherein the control signal corresponds to the control of the on-off of the control positioner 302 by the numerical value signal 1, for example, the positioners 302 with the numbers of a and f are opened, and all the rest are closed; when the first car is cleaned, the locomotive 100 moves to enable the second car to enter the designated position, at the same time, the positioning detection module 401 repeats the above positioning detection actions, the numerical signal output by the adder 402 becomes "2", the control signal output by the PLC control module 403 corresponds to the control of the numerical signal "2" on the on-off of the positioner 302, for example, the positioners 302 with the numbers "d, k" are opened, and the rest are all closed. The self-positioning cleaning of all of the cab roof insulation columns 110 of locomotive 100 can be achieved by simply loading the user control program stored with positioners 302 corresponding to different cab section numbers of locomotive 100 into PLC control module 403.
The specific control method of the insulation column cleaning and positioning system comprises the following steps:
step 1), controlling the locomotive 100 to enter a cleaning area and slowly approach the positioning detection module 401;
step 2), the positioning detection module 401 detects that the locomotive 100 enters a fixed point position, generates a feedback signal and a detection signal, and outputs the feedback signal to the audible and visual alarm to trigger audible and visual alarm, and the locomotive 100 stops positioning;
step 3), the adder 402 receives the detection signal and then performs counting accumulation of the signal, generates a value signal and outputs the value signal, wherein the value of the value signal is a registered value plus 1, the default value of the registered value is 0, and the value signal generated each time can cover the registered value of the previous time;
step 4), after obtaining the numerical value signal, the PLC control module 403 executes a corresponding user program and outputs a control signal;
step 5), the power supply module 404 receives the control signal and then controls different on-off states of the locator 302, so that the locator 302 in the on-state corresponds to the insulation column 110 at the top of the carriage of the positioned locomotive 100;
step 6), controlling the mounting seat 301 to move along the guide rail 200 until the mounting seat 301 is close to the first opened positioner 302 to stop, and then driving the cleaning arm 300 to start cleaning; the mounting seat 301 is controlled by time delay setting to start running along the guide rail 200 again after the cleaning arm 300 finishes cleaning work until the cleaning work of the carriage is finished;
step 7), controlling locomotive 100 to slowly move, enabling the cleaned carriage to move out of the cleaning area until the next carriage to be cleaned enters the fixed-point position, and repeating steps 2) to 6) until locomotive 100 completely completes cleaning work.
