This is how "Tral" works

Moscow think-tank has developed a unique system for accounting, control and access of cars at parking places. New development wont take the duty off a parking attendant, however, it will make his life much more easier. Smart development identifies cars number and opens parking gates in front of it, but only if the car has the right to leave or enter the parking area. Moreover, Tral Parking, how the system in called, never takes doubtful decisions and never hesitates to contact the operator, when it needs help, taking photo of every car, passing the gates of the parking place.

The core of the device is digital video-recorder Tral, developed ten years ago by SMP company. This years innovation in Tral Parking, demonstrated during MIPS-2007 ehxibition, recently held in Moscow. We shall try to describe the system in simple terms, avoiding technical details. Tral Parking consists of several parts: first, it has eyes two videocameras, first one watching carsm entering the parking place, and the second keeping a eye on cars, leaving the shelter. Having a car in its field of vision, the camera transfers its image to systems think factory Tral Parking, a video-recorder looking like a portable (18x3x10 cm) but promising computer.

Now its time for panegyrics the device is able to receive video-signals from several cameras simultaneously and analyses signals my means of original software. First, it scans the image and finds car number white rectangle of given size with figures. Then, the device identifies car nuber and compares it with its database if the number exists in Trals database, the gates open, and the car gets the access to the parking place, actuating car pass sensor and a photocamera, saving car image to video-recorders memory.

Scrupulous developers have foreseen the situation, when computer fail to identify car number, for instance, in case, when the number is covered with dirt or snow. Then computer refers to next higher authority to a parking guard. A guard sees the car on his monitor, where Trals cameras transfer car image, and can permit it to enter the parking place manually. Nevertheless, in this case cars image is also saved in the database. Video-recorder and guards personal computer can communicate online via either local network, or Wi-Fi adapter this is a boast of system developers. Tral recorders are able to register signals of 4 cameras simultaneously, offering multifold possibilities for users.

Systems archive database and car images is stored on a flash drive. The video-recoder is small and can be installed directly into parking gates, because it works in wide temperature range (from 20 to +55 degrees Centigrade). Systems database and archive can be reached remotely, via nerwork. Tral records car images with exact time of leavingentering the parking place, thus leaving no opportunities for passing near sleepless electronic guarg unnoticed. Soon parking guards will have a new assistant smart, alert and honest Tral Parking.
