基于LabVIEW的智能交通路口控制系统设计

Design of Intelligent Traffic Intersection Control System Design Based on LabVIEW

为了对环境车流量进行实时监测,根据监测数据实时调节交通信号灯的计时时间,设计了一款智能交通路口控制系统。该系统上位机以LabVIEW为开发平台,下位机以STC89C52单片机为处理核心;基于RS232串行通信协议,实现了上位机与下位机间的数据实时交换。该智能交通路口控制系统采用LabVIEW虚拟仪器作为上位机开发软件,大大降低了串口通信及逻辑控制的复杂程度,减小了软件设计的工作量,具有智能化、控制方便、实时监测、可靠度高等优点,有较高的实用价值。

In order to realize the real-time detection of the environmental traffic flow, an intelligent traffic intersection control system is designed to make a real-time adjustment for timing of traffic lights.The host computer of this system takes LabVIEW as the development platform,STC89C52 microcontroller as the processing core of the lower machine.The system realizes the real-time data exchange between the host computer and the lower computer based on RS232 serial communication protocol.Using LabVIEW virtual instrument as the host computer development software greatly reduces the complexity of serial communication and logic control and the workload of software.Intelligent traffic intersection controller has such advantages as intelligence,convenient control,real-time monitoring and high reliability, which is of great value in practical application.
