2) Keytop Parking Guidance System Advantages

1. The technique of ultrasonic detector is steady and its anti-jamming capability is
strong.
2. UD's accuracy rate is higher than loop sensor which has problem of weak magnetic
and repeated detection. The base plate of UD is zoom type to avoid the problem
causing by different setting angles without error accumulation.
3. UD has two detection methods, one is to detect the ground, the other is to detect the
vehicles. Both of them are available for all kinds of car park's terrain.
4. The instruction's process chip and memory chip of UD has the function of storing different setting values(keep address setting and self-adapting setting etc.),so it is unnecessary to reset after power-down.
5. The led indicator will be installed at every parking spaces to show the parking
information to the drivers by its colors(free:green, occupied:red).Long-distance
control of led indicator is available by transmitting interrelated commands to UD.
(The led indicator can be on or off regarding to different commands of UD, please
note the UD manual for more details).The color of LED indicator is optional.
6. Using bus system with three layer construction (CCU,ZCU,UD),so the structure is very simple and it is easy to install and maintain. It also can operate without PC and will be not influenced by PC problem.
7. The function of making a reservation, preventing occupancy and anti-robbery is
available.
8. Base plate of UD:it can swing 15 degree to be installed forward and backward, so angle's variation improves its detection accuracy rate.
9. Network Wire Connection: Using network wire to connect the components of PGS makes the installation easier and reduce much installation time and lower the connection error.
10. Energy conservation function: the led indicator will be on only when it is free, or
it will be off, which will reduce 25%-33.3% of car park's energy charge.
