Collision problem

[a9080109]

[ FlexSim 20.0.10 ]

I want to know how to use pf to control the time of collision, so that I can collect data

agv-avoidance-rc.fsm

[jason_lightfoot_adsk · Accepted solution]

Detect the OnCollision event in an eventTriggeredSource activity and then use a StatsCollector to collect the data.

But what I want to do is I want to give the collision time like five seconds, can it be done with PF?

[jason_lightfoot_adsk]

I don't understand your sentence.

[a9080109]

i mean when the collision happens i want to use pf to give the whole process a delay time

For example I only want the collision to end after five seconds, is this controllable?

@Jason Lightfoot

Can you tell me if you have any good suggestions?

[jason_lightfoot_adsk]

You know:

• how far apart the transporters are
• the size of the spheres
• the velocities.

so from that you could calculate the duration. If you want to have the collision last for a certain time then you'll need to solve it using basic algebra.

[a9080109]

Can you provide a case? For example 1 second?

[jason_lightfoot_adsk]

It's time = distance/speed - you should be able to manage that.

I don't understand how do I bring data into flexsim

[jason_lightfoot_adsk]

It occurs to me now that you might just want to hold the AGVs for 5 seconds before they continue once the collision event has been detected - and not that you want the spheres to be colliding for exactly 5 seconds - is that right?

[a9080109]

yap is to stay in that state for five seconds, after which it will continue to execute the task

[jason_lightfoot_adsk]

Okay so you should probably just stop the AGVs for the 5 seconds when you detect a new collision. If you have a problem with double detection then you'll need to record that the two AGVs are in a collision already and test for this when the second firing of the collision event happens.

I don't know very well!! Could you please give me an example?

@Jason Lightfoot

I would like to ask if I am going to add other objects now, how can I adjust my model to make it run smoothly. Also in the TRAVEL settings, can I do it in another way? Instead of using CURRENT.DEST to specifyagv-avoidance-rc-jl.fsm

[jason_lightfoot_adsk]

Of course - add the other agvs to the same process flow. See instanced process flows. You already know how to create travel tasks - the example just used a label for ease.

@Jason Lightfoot

I used the case you provided to create a similar activity in general pf, but he doesn't seem to have a way to delay like in the case, what's wrong with me?0421.fsm

@Jason Lightfoot

In addition, I also want to ask if I can control which side will back up when a collision occurs? As far as this model is concerned, the car on the left is backing up

[jason_lightfoot_adsk]

You're using the term 'current' in a general process flow. It doesn't mean the same thing there. You need to write a pointer to the agv on the token using the event triggered source.
