Embodiment Construction

[0047] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] For the convenience of understanding the technical scheme of the present invention, the related concepts of the present invention are briefly introduced as follows:

[0049] Transmission of wireless signals: Under open space conditions, a wireless transmitter A with a fixed position transmits a certain power radio frequency signal, and the strength of the radio frequency signal is inversely proportional to the square of the distance to point A. We can use the formula: T r =KQ / R 2 To represent. Here T r Represents the signal strength at a distance of r from the wireless transmitter A, Q represents the signal strength at the antenna end of the wireless transmitter, and K can be simply considered as the attenuation coefficient, which mainly depends on the height of the transmitting and receiving antenna, antenna gain, ...

Abstract

The invention relates to a wireless radio track technique, under-well work position track and the management of segment charge road, wherein it utilizes the micro power wireless semaphore with fixed position to wirelessly communicate with pass-by wireless license plate, to record the position and time when the wireless license plate pass each semaphore, to track the real line of vehicle or other movable target. The invention has the advantages that: the system has simple structure, low cost and easy maintenance, to solve the problem of under-well worker positioning, charge and segment charge. And it can avoid additive worker, only based on present charge manage system.

Description

technical field [0001] The invention relates to micro-power wireless communication, vehicle location tracking technology and non-stop charging management. Background technique [0002] Existing vehicle positioning tracking generally adopts the GPS positioning tracking method; the management of existing road tolls generally adopts an IC card or a magnetic card that records the import address information at the entrance, and then reads out the information in the card at the exit. The information of the recorded import location is used to carry out the method of billing; in addition, the method of automatic billing of the long-distance RFID system is also adopted in some places. [0003] GPS positioning tracking method and its existing problems: [0004] The vehicle being positioned and tracked receives the positioning signals transmitted by four (at least three) GPS satellites at the same time through the GPS receiving terminal installed on the vehicle, and calculates the lon...
