The mast design has two types. One design use fixed position for processing box (as shown in figure above) and other design let the box to gone up and down with using a semi elevator to make processing box more accessible for convenient maintenance.
For working in outage, backup power is considered. Also if Outagelastedmore than predicted timeand batteries charges go below acceptable value, controller board automatically will turn off the system and when AC powerreconnected will turn on it again.
Output power of UPS chosen appropriate to whole system power consumption and UPS will used In addition to the emergency power supply system for protecting system against noise and some other destructivepowerchanges.
This subsystem is responsible for well functionality of system and powering on it, as is possible. Also restarting system if needed (power failure…) to maintain system so maximum proper uptime achieved.
The watch dog method utilized to control well working of various parts of software or hardware. And if a problem occurred (in hardware or software) controller lunch a specified routine to resolve that problem or restart system.
Since the final usage of vehicles info is on central unit, the data transfer is a main part of solution.
For this purpose we can use several standard network connections based on Ethernet connection, as optical fiber, wireless LAN or usual LAN cable.
It can be noted if we just transfer the offender cars info, Willrequire lessbandwidth and can use even GPRS.
The needed bandwidth in any place is calculated to fit mean transfer rate of cars by knowing that every full transfer record has 120 kb volume.
Also if network failed, records write-in local system an when connection reconnect, all data Will be transferred with Prioritizing. The system has the recording ability to store more than two months traffic.
As this system will be used in various weather conditions then its doors, body, holes and etc are designed to be insulated and so whole system are completely sealed. To adjust the temperature and humidity, industrial air handling systems (proportionate to system needs) are used. as a result thissystemwork asaclosedcycle and inside air has no contactwith outside air.
Thus by adjusting the temperature and moisture and avoid dust, safe operation of equipment significantly increased.
This system is used successfully in areas with a temperature range of -30 °C to +45 °C
Alarm And SMS System
In case of any unauthorized access or extreme stroke, alarm message will send to central unit through project communication platform. In addition, images of surveillance and anti-theft cameras will be shown on main screen with playing sound alarm in monitoring room. Also it should be noted that for those conditions presets are considered and all images stream will be save automatically both in local station and central server.
Once thecrisis is detected (risk and problems occurred such as: Power failure, network failure, stroke, theft and unauthorized access), a message that contains system and event information will be created and immediately send to appropriate person from preloaded list.
No Need To Gate
Because of advantage income from special algorithmic software and power full mechanisms used in this design, system has Simplehardware installation and there is no need to use additionalcomponents Installedin theroadbed or gate on the road.
