Parking space intelligent indication lamp system based on radar sensing and realization method thereof

Abstract

The invention discloses a parking space intelligent indication lamp system based on radar sensing and a realization method thereof. According to the system, the advantages of radar sensing and an intelligent LED are combined, and the novel application for parking lot parking space indication is provided. An intelligent indication lamp device is formed by a radar sensor, a signal modulation and transmission module, an echo signal acquisition and processing module, an LED controlling and driving circuit, and an LED. A one-to-more layout structure is employed between a front-end device and a parking space, parking space existence sensing and judgment by radar sensing and the number of available parking spaces are matched to control the brightness degree or luminous color of the LED lamp. According to the system and the method, while the all-weather, real-time and high sensitivity induction is realized, the existence and number of the available parking spaces can be indicated, and a convenient, efficient and practical parking guiding system is realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent parking spaces, and in particular relates to an intelligent LED parking space indication system based on a radar sensor. Background technique [0002] With the rapid increase of the number of motor vehicles in our country, the difficulty of parking has become one of the main traffic problems in large and medium-sized cities. Parking lots are often difficult to find, and especially in large parking lots, the search for vacant parking spaces has low efficiency, Difficult and time-consuming issues. Therefore, there is an urgent need to develop an efficient and practical parking space guidance system to meet the rapidly developing traffic demand. [0003] The existing parking space indication and guidance system mainly has the following problems: (1) The content of the indication is complicated, and the driver needs more time to judge; (2) It can only reflect the number of vacant parking spaces i...

Problems solved by technology

[0003] The existing parking space indication and guidance system mainly has the following problems: (1) The content of the indication is complicated, and the driver needs more time to judge; (2) It can only reflect the number of vacant parking spaces in the entire parking lot, but cannot reflect the specific vacant parking space location; ( 3) The cost of the video system is high, and it is restricted by light and obstacles; (4) Infrared and ultrasonic sensing are greatly affected by temperature and light, restricted by obstacles, the sensing distance is limited, and the accuracy is poor. Each device can only detect a parking space
