Electronic map based low-power-consumption container positioning device and method

Abstract

The invention belongs to the field of container positioning equipment, and especially relates to an electronic map based low-power-consumption container positioning device and a method. The electronic map based low-power-consumption container positioning device comprises a GPS / Beidou dual-mode positioning module, a gyroscope / acceleration sensor module, a GPRS communication module, a power supply module and a dormant area information module. Through the dormant area information module, the container positioning device is started to get into a dormant state so as to reduce the power consumption when the container positioning device is judged to get into a fixed area or a user-defined electronic fence area on a preset electronic map, wherein the dormant state is set to be a state at which the GPS positioning frequency is automatically reduced and the GPRS communication module and the gyroscope / acceleration sensor module are closed, so that a lot of power is saved, and the working time of the container positioning device is prolonged.

Description

technical field [0001] The invention belongs to the field of container positioning equipment, in particular to a low-power consumption container positioning device and method based on an electronic map. Background technique [0002] In recent years, containers have been widely used in the international and domestic logistics industry. As an important terminal in the logistics industry, containers carry more than 80% of the freight circulation. In order to meet the development needs of anti-terrorism, cargo safety, and easy query and positioning, intelligent containers must be greatly developed and used, and intelligent containers can implement real-time information, visualization, and transparency in the entire logistics chain. For remote monitoring, tracking and management of container location information in the supply chain, positioning equipment needs to be installed on the smart container. The existing container positioning equipment mainly uses micro batteries for powe...

Problems solved by technology

However, when containers appear in some specific areas, such as storage yards, distribution centers, and docks, they usually stop for several days due to process and formalities, and satellite signals in these areas are prone to poor or even no signal, or When containers appear in areas with poor signals such as tunnels and mountainous areas, or other custom-defined areas that do not require positioning, the device will consume a lot of power in order to search for satellite signals. Therefore, it is urgent to provide a low-power container positioning device and method based on electronic maps
