Picture show that they are measuring weight. Three IR sensors are being used which tell the exact position of the truck so that the weight can be measure.

I want to understand a flow of system in which those three sensor are working.
What happens when the first sensor is high, does system monitor it continuously or once in main loop?

There is nothing about the working principle in the product's description and the brochure though. What I can understand is, Outputs of these 3 IR sensors are connected to an STM microcontroller and the digital value of those 3 pins of the MCU is being checked continuously. Not once.

I'm just taking that image for example.

I'm trying to understand the general process of how a truck comes on track to measure weight using sensors.

I understand that to find the correct position, the first and third sensor should be low and the middle sensor should be high as show the image show in link http://www.monilautomation.com/tenker-alignment-system.php
I don't understand how logic would be used for a public declaration that instructs the driver to the correct position.
If the truck has stopped on the first sensor then it should be announced to go forward, if it is ahead a lot at third sensor , then it should be told to go back

Hi,
You measure the length of the truck using the first sensors in a row. (also the speed Time to detect front and rear)
Length of the scale is known length of truck measured.
total weight = sum of each pillar/6
