Distance detection device for automatic drive

Abstract

The invention belongs to the technical field of automatic drive and discloses a distance detection device for automatic drive. The distance detection device for automatic drive comprises a program loading module, a monitoring module, a circuit self-inspection module, a central control module, a wireless communication module, a positioning module, a distance measurement module, an alarm module anda display module. According to the device, through utilization of the distance measurement module, the distance measurement business of a communication network can be realized in normal data communication business, so two businesses of communication and distance measurement are not influenced mutually, the distance measurement cost in the network is reduced, the node energy consumption is reducedand a life circle of the network is prolonged; and moreover, through utilization of the alarm module, when a traffic accident occurs, the alarm is carried out timely, the manpower monitoring is reduced, and the rescue efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to a distance detection device for automatic driving. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Self-driving vehicles (Autonomous vehicles; Self-piloting automobile), also known as unmanned vehicles, computer-driven vehicles, or wheeled mobile robots, are intelligent vehicles that realize unmanned driving through computer systems. It has a history of decades in the 20th century, and it has shown a trend close to practical application in the early 21st century. For example, Google's self-driving car obtained the first self-driving vehicle license in the United States in May 2012, and it is expected to be released in 2015. It will enter the market for sale in 2017. However, in the existing autopilot ranging, sending and receiving ranging packets will occupy limited wireless broadb...

AI Technical Summary

Problems solved by technology

[0007] In the existing automatic driving distance measurement, sending and receiving distance measurement packets will occupy limited wireless broadband resources, and the transmission of data will inevitably consume node energy; at the same time, when encountering an accident, it is often learned through monitoring, which is time-consuming and laborious, resulting in Rescue not in time

[0008] The higher grid density of the existing technology greatly increases the time for establishing the database, and also causes difficulties for the later database update, which makes the fingerprint positioning method have strong limitations in practical applications.
