摘　　要：针对大型停车场车位多、用于车位检测的传感器多和布线不方便等问题,提出了基于ZigBee和RS-485总线相结合的混合通信方式。设计了停车场车位信息检测和显示系统,将停车场划分为若干个区域,区域之间通过ZigBee进行无线通信,区域内部通过RS-485进行数据通信。每个区域主控制器主要由MCU最小系统、按键、DC-DC变换电路、掉电存储芯片、IC卡读写器、报警蜂鸣器、LED点阵显示装置、通信电路和车辆进出红外检测电路等组成。该系统可实现停车场车位状态数据的实时检测、传输和显示,并且具有车辆进出IC卡管理等功能。On a large parking it is not convenient to use more sensors and wiring problems. Based on Zig- Bee, a mixed communication mode of combining RS--485 bus is put forward. Car park could be divided into several regions, through the ZigBee wireless communication between area, regional internal data communica- tion through the RS--485, and each area is mainly composed of MCU controller circuit minimum system, but- tons, DC--DC transform, power storage, IC card read and write, buzzer alarm, LED dot matrix display, com- munication circuit and vehicles in and out of the infrared detection circuit. The system can realize the parking lot parking state data real-time detection, transmission and display, and a vehicle in and out of the IC card man- agement, and other functions. It has been verified by practice, the effect is good.
