Problems solved by technology

The traditional data reporting compression strategy is relatively simple, and most of them cannot take into account the consumption of data traffic and the timeliness of data
For example, there are three functional indicators for uploading data: data volume, compression rate, and upload frequency; the basic relationship between the three is that the larger the data volume, the greater the information volume, the higher the theoretical compression rate, and the lower the upload frequency per unit time. The worse the timeliness

Abstract

The invention relates to the technical field of data transmission technology and discloses a positioning device, a positioning system and a data transmission method. According to the invention, the data transmission method of the positioning system includes steps of calculating a gap distance between a positioning point collected by the positioning device and a valid point in last positioning; setting the collected positioning point as a valid point and setting the valid point into a report cache list if the gap distance is greater than or equal to a preset threshold value; and compressing data in the report cache list and output to a server if the quantity of valid points in the report cache list is greater than or equal to a first report threshold value and the interval time from last reporting becomes no shorter than the first report interval time. Compared with the prior art, data transmission traffic consumption of the positioning system and timeliness can be taken into consideration at the same time. Therefore, traffic consumption can be reduced and data can be output timely.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a positioning device, a positioning system and a data transmission method thereof. Background technique [0002] The GPS (Global Positioning System) of the wireless communication device reports the information collected by the built-in GPS of the device to the background server through the mobile network according to the requirements of the application scenario. Among them, an important functional indicator of the uploaded data is how to balance the flow consumption of the device and The relationship between data accuracy, timeliness, and validity. The traditional data reporting compression strategy is relatively simple, and most of them cannot take into account the consumption of data traffic and the timeliness of data. For example, there are three functional indicators for uploading data: data volume, compression rate, and upload frequency; the basic relationship between the thr...
