Abstract

The invention relates to a positioning method for transportation means. The method includes the following steps of: 1) first satellite measurement step which further includes an initial positioning distance measuring step and a carrier phase smoothing pseudo-range differential step; 2) extra satellite measurement step: the coordinates of at least four extra satellites and second time point calibration positioning distances corresponding to each extra satellite are obtained according to the first satellite measurement step; and 3) transportation means coordinate determination step: the coordinates of the transportation means at a second time point are obtained according to the coordinates of the satellites and the second time point calibration positioning distances of the satellites which are obtained in the step 1) and the step 2). In addition, the invention discloses a positioning device, a monitoring device and a monitoring system for transportation means. The positioning method, positioning device, monitoring apparatus and monitoring system for transportation means of the invention have the advantages of very high positioning accuracy and powerful functions, and can monitor the driving states of the transportation means in real time, and can give an alarm when an abnormal state appears.

Description

technical field [0001] The invention relates to the field of vehicle monitoring, in particular to a positioning method for vehicles, a monitoring module, monitoring equipment and a monitoring system. Background technique [0002] The rapid development and wide application of the Internet of Things technology has brought a qualitative leap to people's lives. As an important part of the Internet of Things, the Internet of Vehicles has attracted more and more attention. At present, although the logistics industry based on vehicle transportation is developing rapidly, the supporting logistics vehicle monitoring technology is still relatively lagging behind. figure 1 It schematically shows the structure of the vehicle monitoring system in the prior art. like figure 1 As shown, the monitored vehicle is positioned through GPS (Global Positioning System, Global Positioning System) and ordinary electronic map, and the acquired position information is passed through GPRS (General Pa...
