Parking space state sensing and indicating device and parking space state sensing and indicating method

Abstract

The invention relates to a parking space state sensing and indicating device and a parking space state sensing and indicating method. The parking space sensing and indicating device comprises an infrared distance detecting module, a high-light LED indicating module, a communicating module and a control module, wherein the infrared distance detecting module is used for continuously detecting the distance between a mounting position of the parking space state sensing and indicating device and a parking space ground surface or the top portion of an object placed on a parking space according to a specific time interval; the high-light LED indicating module is used for indicating parking space state information, when the parking space is vacant, an LED flashes according to a certain time interval, and when the parking space is occupied, the LED extinguishes; the communicating module is used for sending parking space state information outside; the control module is used for judging whether a vehicle is parked on the parking space according to distance changes detected by the infrared distance detecting module and used for driving the high-light LED indicating module to indicate the parking space state information and driving the communicating module to send out the parking space state information. The parking space state detecting module and the parking space state indicating module are integrated in the parking space state sensing and indicating device, and therefore mounting efficiency is improved and system cost is lowered.

Description

technical field [0001] The invention relates to a parking space state sensing technology, in particular to a wireless parking space state sensing and indicating device and method. Background technique [0002] Existing parking space detection technologies include ultrasonic detection method, geomagnetic detection method and video detection method. Ultrasonic detection method has high power consumption and short detection distance, while geomagnetic detection method has low accuracy and video detection method has high cost. The drawbacks of these prior art have limited their application in parking lots. In addition, the existing parking space indication method is to set up a separate LED indicator light above the parking space. When there is a car in the parking space, it will always be red, and when there is no car in the parking space, it will be always green, so as to generate parking induction. But it is also prone to red and green mixed situations, and green empty parki...

Problems solved by technology

However, it is also prone to red and green mixed situations, and green empty parking space indicators are often not easy to find

All the red or green lights in the parking lot will cause visual discomfort

Moreover, all parking spaces are either red or green, resulting in huge power consumption
