Embodiment Construction

[0026] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0027] A high-precision parking space detection system, such as figure 1 As shown, it includes a parking space detection server, a wireless parking space detection network and at least two parking space detectors installed on each parking space. The parking space detection server is connected to each parking space detector through a wireless parking space detection network, and the parking space detector is installed in the parking space center. Around the point, the parking space detection server detects multiple parking spaces on each parking space at the same time to determine whether a car is parked in the parking space. The number of parking space detectors installed on each parking space is preferably 2, and two parking space detectors are installed as an example for each parking space below to illustrate, as figure 2 As shown, two parking ...

Abstract

The invention relates to a high-precision stall detection system and method. The high-precision stall detection system by comprising a stall detection server, a wireless stall detection network and stall detectors, wherein the stall server is connected with the stall detectors through the wireless stall detection network, at least two stall detectors are arranged on each stall, and a certain distance is maintained between the stall detectors. The method comprises the steps that: 1, at least two stall detectors on the same stall simultaneously acquire data through respective geomagnetic sensors and send data to the stall detection server through an AP in the stall detection network; and 2, the stall detection server receives the data of the at least two stall detectors on the same stall and then carries out judgment by using comprehensive information of the at least two stall detectors. The high-precision stall detection system is reasonable in design, solves the problem of detection blind region when a vehicle is remained on a zero counteracting point of the stall detectors, is increased in accuracy rate of stall detection, and fills up the blank of a stall detection technology.

Description

technical field [0001] The invention belongs to the technical field of parking space detection technology, in particular to a high-precision parking space detection system and a detection method thereof. Background technique [0002] Using geomagnetic sensors to detect parking spaces is a new way of detecting parking spaces in recent years, and is widely used in parking lot management. When a parking space detector with a geomagnetic sensor is used to detect a parking space using geomagnetic signals, it is installed under the surface of the parking space. Whenever a vehicle enters or leaves the parking space, the parking space detector detects the arrival of the vehicle according to the change of the magnetic field signal around the ground. and leave, and after the signal stabilizes, send this signal to the receiving device. With the deepening of the application, it is found that the interference of the external environment often leads to the reduction of the detection accu...
