the working area layout is started by the warning area S until the termination area Z layout is completed, and the working area layout is implemented according to the following flow: after the traffic cone retracting vehicle reaches a preset place, parking and observing in an emergency lane, starting a right double-lane placement operation preparation instruction by one key, and waiting for the moment of cutting into execution operation instruction, wherein the traffic cone retracting vehicle is positioned in the emergency lane at the tail end of the S-warning area. Under the operation preparation instruction, the front side collecting and releasing device 2 and the rear side releasing device 6 are switched from a transition posture to an operation posture, the sensor obtains a positioning signal in a 90-degree overturning mode, the program executes the transfer instruction, the front transfer device 10 and the rear transfer device 11 respectively convey traffic cones to the front side collecting and releasing device 2 and the rear side releasing device 6, after the traffic cones are in place, the sensor is detected to return the positioning signal, the center console prompts that the distribution operation state can be entered, and the confirmation key is displayed. And executing different processes and control logic according to the execution of the lane closing operation and the lane passing closing operation.
When the expressway traffic lane operation is executed, an emergency traffic lane and a traffic lane are usually closed, and the execution process is as follows:
1. and (3) placing operation: under the condition that the vehicle is allowed by the road vehicle, the equipment is started, constant-speed cruising is started according to construction requirements, then a cab operator (non-driver) executes a placement operation instruction, at the moment, the rear side placement device 6 positioned at the rear side right limit starts placement operation, once placement is completed, the rear side placement device 6 slides to the left at a certain distance, and next placement is performed until all traffic cones inside the rear side placement device 6 are placed. At this time, the emergency lane forms a complete guiding oblique line cone area, the traffic cone retraction vehicle is still positioned in the middle of the emergency lane, and the center console prompts whether the traffic cone is completely thrown in the rear side throwing device 6 or not, and whether the next operation is executed. Since the lane changing to the left is to be executed subsequently, the traffic cone retraction vehicle stands by in situ, the driver confirms the lane changing time, and at this time, the rear side delivery device 6 continues to receive the next traffic cone conveyed by the rear transfer device 11, slides to the left limit position for stand by, and returns a positioning signal.

When the expressway overtaking operation is executed, only the overtaking lane is usually closed, and the execution process is as follows:
1. and (3) placing operation: under the condition that the road vehicles allow, the equipment is started, the emergency lane is changed to the overtaking lane, the constant-speed cruising is started according to the construction requirement, then a cab operator (non-driver) executes a placement operation instruction, at the moment, the rear placement device 6 positioned at the rear right limit starts placement operation, once placement is completed, the rear placement device 6 performs distance sliding leftwards, and next placement is performed until all cone barrels in the device are placed. At this time, the passing lane has formed a complete guiding oblique line cone area, the equipment is located in the middle of the passing lane, the front side collecting and releasing device 2 starts to execute the throwing operation, and enters the straight line throwing (2:H, section G in the attached drawings), meanwhile, the rear side throwing device 6 continues to receive the next traffic cone conveyed by the rear transfer device 11, slides to the left limit position for standby, returns the locating signal, and starts to execute the circular throwing stage of the front side collecting and releasing device 2 and the rear side throwing device 6. At this time, when the front side retracting device 2 performs the operation, the rear side releasing device 6 starts to receive the new cone delivered by the rear transferring device 11, and enters the operation state when the front side retracting device 2 finishes the operation, and vice versa.
