Bluetooth car park management system advantages: 1, Bluetooth products are optical excitation, wake-up, high-tech Bluetooth communication crystallization speed reader, reading distance away, with good directional control the reading distance (1-5 meters 5-10 m, 10-20 m adjustable), 10-60 kilometers per hour without stopping reader. 2, up and down ramps, entrances corners do not stop the reader, to avoid the vehicle stalled, Banpo start. 3. The vehicle is not a protective film (such as anti-riot film) influence, applies to all vehicles. 4, do not stop, do not open the window reader; the owners are no longer subject to bad weather snow storms affected the car window. Do not stop the reader greatly improve traffic throughput, rush hour traffic jams are no longer queuing phenomenon. 5, no mutual interference between the reader (the use of advanced technology and code division multiple access Bluetooth communication), good direction, an effective solution to the problem around, lane mutual interference. 6, the frequency of 433MHZ, the frequency of human no radiation damage. 7, the card is good stability, product jamming, anti-fading capability, without the interference of other communications products (such as: mobile phones and other wireless communication products). Phone calls will not burn cards. 8, Wiegand 26/34, RS232C / 485 interface adaptation, has good scalability can be common in other car parks, highways, long-range identification fields. / ID card device is fully compatible with existing IC. Bluetooth remote reader range of applications: 1. Suitable for military and political authorities, internal parking system units, units, departments and units sent a car system. 2. Bluetooth remote parking system is the preferred unattended underground garage, garage monthly card, a dedicated garage. 3. Villa. Residential areas, commercial buildings is preferred. 4. Finance and insurance, public places of choice. 5. Various remote vehicle inspection fees is preferred. For example: ETC, truck management, logistics management system of the vehicle. 6. Distance is measured anti-collision control. (More than one lane running test smelting, machinery plant and other anti-collision alarm system distance) Note: mainly applied to fixed users more places
