Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see Figure 1-2 , in the embodiment of the present invention, a kind of double bucket detection method for parking space, specifically comprises the following steps, starts:

[0021] The first step: the vehicle drives into the parking space;

[0022] Step 2: The geomagnetic sensor in the second parking space detector perceives the change of the magnetic field. When the change of the magnetic field reaches the preset change threshold, it starts to trans...

Abstract

The invention discloses a method for detecting a parking space through double barrels. The method comprises: 1, a vehicle driving into the parking space; 2, a geomagnetic sensor in a parking space detector II sensing the change of a magnetic field, and when the change of the magnetic field reaches a preset change threshold value, starting 125KHZ wireless signals to be transmitted; 3, the parking space detector I being awakened by a 125KHZ wireless signal transmitted by the parking space detector II and enters a receiving mode; 4, the parking space detector I judging whether the data is sent bythe parking space detector II or not according to the received data; 5, if so, taking out a received signal intensity value, and judging the state of the parking space according to a trigger threshold value; and 6, if not, continuing to enter a low-power-consumption interception state, and ending. The double-barrel parking space detection technology, the radar technology, the ultrasonic technology and the like have the advantages that the frequency is low, the penetrability is good, and 125Khz wireless radio frequency signals can be suitable for severe weather such as rain and snow, so that the problem of low parking space detection accuracy under the condition of severe weather such as rain and snow is solved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a double-barrel detection method for parking spaces. Background technique [0002] Parking space, that is, a parking space, refers to a place for parking, including open spaces and indoor spaces. There are two types of parking spaces: free parking spaces and paid parking spaces. In the management of the parking lot, the main source of income of the parking lot management company is to provide parking services through the rental of parking spaces and to collect parking fees. The parking spaces are often divided into fixed parking spaces and temporary rental spaces. [0003] Existing parking space detection technologies mainly include geomagnetic detection technology, geomagnetic plus radar detection technology, pure geomagnetic detection technology has low accuracy in detecting parking spaces, and is prone to false alarms, and geomagnetic plus radar dual-mode detectio...
