Abstract

The invention discloses an expressway agglomerate fog pre-warning system. According to the system, the expressway environment parameters are collected by using a digital sensor technology; the data is sent to a processing module by using a Zigbee wireless sensor network; the processing module carries out data fusion according to a pre-established mathematical model; if the pre-warning condition is satisfied, the pre-warning information is displayed through an LED (Light Emitting Diode) dot matrix display module at the passageway of the expressway; and at the same time, the work personnel can take corresponding steps to ensure the smoothness and the safety of the expressway. The expressway agglomerate fog pre-warning system has the advantages of low cost and flexibility and convenience in arrangement, and can be widely applied to the field of expressway safety management.

Description

technical field [0001] The invention relates to sensor technology and Zigbee wireless sensor network technology. Specifically, temperature and humidity sensors and dust sensors are used to collect environmental parameters, and Zigbee wireless sensor network and data fusion and analysis are used to form a highway fog early warning system. Background technique [0002] Temperature and humidity sensors and dust sensors are sensors used to measure the temperature, humidity, and dust density of the surrounding environment. They convert the measured results into analog or digital signal outputs for use by microcontrollers. [0003] ZigBee wireless sensor network technology is a two-way wireless communication technology with short distance, low power consumption, low data transmission rate and low cost. It can establish a small and dedicated special network mechanism that is separated from the fixed network infrastructure and forms a special network mechanism on the connected devic...
