One-key real-time calibration system based on field ranging information and calibration method thereof

Abstract

The invention discloses a one-key real-time calibration system based on field ranging information and a calibration method thereof. The calibration system comprises a positioning system background anda positioning base station, wherein the positioning base station comprises a positioning ranging module, an RF wireless communication module, a power management module and a first network communication module; the positioning system background comprises a ranging information processing unit, a second network communication module, a base station ID information encoding / decoding unit, a control instruction analyzing / executing unit and a back-end calibration processing unit. The system can greatly reduce the workload of field deployment calibration, improve the deployment efficiency and reduce the subjective error and error risk of manual measurement to the greatest extent; in addition, the system can achieve remote calibration by means of the remote network communication function of the positioning system, so that the efficiency is improved, and the calibration cost is reduced.

Description

technical field [0001] The invention relates to distance calibration technology, in particular to a one-key real-time calibration system and calibration method based on on-site distance measurement information. Background technique [0002] With the rapid development of mobile Internet of Things, smart home and sensor technology, under the general trend of "Made in China 2025", industrial automation, smart manufacturing, and smart factories have been rapidly developing in the Yangtze River Delta and Pearl River Delta. The core supporting technologies of networking, smart factories, and unmanned storage have been greatly developed. With the help of mobile phone Bluetooth, Bluetooth iBeacon, wifi, Zig-bee, and ultra-wideband UWB technologies, indoor positioning technology for different applications has been widely popularized. Applications, especially UWB positioning, stand out for its advantages of high precision, low cost, and high reliability. Due to its particularity, ind...

Problems solved by technology

[0005] The above-mentioned first method is complex and changeable due to the site conditions, especially the phenomenon of irregular space and obstacles in the space, and human operation will introduce many subjective errors, resulting in inaccurate measurement, time-consuming and labor-intensive; the second method The method uses the distance measurement function of the base station itself to complete the measurement, but it needs to be manually entered into the positioning system, and errors may occur during the entry process. At the same time, the development of a dedicated software distance measurement platform will increase manpower and maintenance costs
