The environment such as practical section position, traffic congestion situation, seasonal climate, which change, carries out corresponding programming adjustment.
Functional flow diagram implements logical description：
1. microcontroller timer timing judges whether the time arrives setting time：
"Yes" then carries out data acquisition (reading each pressure sensor value in crossing) to pressure sensing area, and then basis has been set "No"
It sets interval query time and continues inquiry (returning to upper level)
2. judging whether someone according to the pressure sensor data read：
"Yes" then judges that whether two major trunk roads someone, "No" then return to upper level and continue to inquire crossing time lamp road conditions
3. judging major trunk roads whether all someone
"Yes" then continues to judge whether major trunk roads number difference is larger, and "No" is then let pass someone's trunk according to preset program
Road
4. judging whether major trunk roads number difference is larger
"Yes" then judges whether number arrives setting time compared with Multiple Intersections timer, and "No" is then taken turns according to preset program successively
Banish row
5. whether the more person crossing waiting timer of number (arrives timer time, system is set as 5min, timer time
5min is not arrived, cannot continuously be let pass, and is continuously let pass to prevent the more crossing of pedestrian)
"Yes" then controls the more major trunk roads of traffic lights (green light) clearance number, and "No" is then let pass major trunk roads fewer in number
The division in the areas Tu3Hou Deng is provided with 8 marquis's lamp regions 4 as schemed in corresponding crossroad non-motor vehicle traffic areas
(having the side of traffic lights, it is desirable that marquis's lamp offset traffic lights 3 is no more than 1m), the areas Hou Deng area selects 3m × 2m (actually can basis
Different road conditions are adjusted), waiting embedding under lamp region has pressure sensing information acquisition system.Hou Dengqu has clear yellow line to divide,
So that specification pedestrian waits lamp, current behavior.
Fig. 4, Fig. 5 are the main distributed areas of pressure sensor device sensor, and the quantity of sensor 2 is according to the reality of sensor
Range and thereon load-carrying (earthing, steel plate 1, roadbed and time lamp crowd weight) determine that the arrangement of sensor is using nine grids
Arrangement, ensures that force acting on transducer is uniform, uses unbalance stress for a long time with no-sensor, service life is caused to reduce even
It destroys.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
