Embodiment Construction
[0049] refer to figure 1 , the present invention a kind of vehicle detection method utilizing navigation satellite signal, comprises the following steps:
[0050] A. Detect the quality of the navigation satellite signal received by the parking space when there is no car, and calculate the quality of the reference signal without the car;
[0051] B. Detect the quality of the navigation satellite signal received by the parking space in real time, and calculate the quality of the real-time satellite signal;
[0052] C. According to the quality of the car-free reference signal and the quality of the real-time satellite signal, the real-time status of the parking space can be judged.
[0053] refer to figure 2 , as a further improvement of the vehicle detection method using navigation satellite signals, the step A includes:
[0054] A1. Detect and record the quality of the navigation satellite signal received by the parking space when there is no car;
[0055] A2. According to...

The invention discloses a vehicle detection method and a vehicle detection system using navigational satellite signals. The method comprises: detecting quality of the navigational satellite signal received when no vehicle is parked at a parking space, and working out quality of a no-vehicle reference signal; detecting quality of the navigational satellite signal received by the parking space in real time, and working out quality of a real-time satellite signal; and therefore, judging real-time status of the parking space according to the quality of the no-vehicle reference signal and the quality of the real-time satellite signal. The system includes a no-vehicle reference signal quality detection unit, a real-time satellite signal quality detection unit and a parking space status judging unit. Related electronic circuits implemented in the vehicle detection system is high in integration level and low in cost, compared with a device adopting a ground induction coil vehicle detection technology, the vehicle detection system has better installability and maintainability. Furthermore, as vehicles are highly consistent in attenuation characteristic of navigational satellite signals, compared with the geomagnetic vehicles detection technology, the vehicle detection method can achieve greatly improved detection accuracy. The vehicle detection method and system can be widely applied to the field of vehicle detection.
Description
technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a vehicle detection method and system using navigation satellite signals. Background technique [0002] With the development of the domestic automobile industry, the number of urban vehicles has increased sharply, and the demand for outdoor parking lots has increased, which has increased the difficulty of outdoor parking lot management. Through vehicle detection technology, information such as the number of vacant parking spaces in the outdoor parking lot and the parking time of the occupied parking spaces can be obtained. This information can effectively help the parking lot manager manage the parking lot more effectively, and also help car owners find nearby vacant outdoor parking spaces more quickly. Therefore, the demand for outdoor vehicle detection technology is becoming stronger and stronger. [0003] Currently, the vehicle detection technologies used in outdoo...
