Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment, further set forth the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after reading the present invention, those skilled in the art will understand various aspects of the present invention Modifications of the valence form all fall within the scope defined by the appended claims of the present application.

[0021] See attached figure 1 , is a positioning device based on GPS / Beidou, which includes: GPS / Beidou integrated positioning module, STM32L single-chip microcomputer control module, NB-IoT communication module and power management unit. The volume of the positioning device is only 3*3*3cm, and it can continue to work for 2-3 years when the data is sent only once a day, which is obviously better than the existing similar products in the market. And the miniature low...

Abstract

The invention discloses a miniature positioning device with low power consumption and belongs to the technical field of electronic information. An NB-IoT communication technology is adopted in combination with a Beidou positioning system to complete the design of the positioning device, and the problem that it is hard for positioning devices to make a breakthrough in size and power consumption issolved. The positioning device comprises a GPS / Beidou integrated positioning module, an NB-IoT communication module, an MCU main control module and a power management module. Each module transmits data through an interface of the MCU main control module; through a separated working mechanism of the modules and a sleeping mode, the stability of the device can be better improved, the battery life ofthe device can be better prolonged, and the device can work continuously for 2-3 years in a low-frequency working mode.

Description

technical field [0001] The invention belongs to the technical field of electronic information. In particular, it relates to a miniature low power consumption positioning device. Background technique [0002] With the acceleration of the pace of life, the impact of item location information on people's lives is more obvious. Especially in recent years, with the rapid rise of shared goods and smart monitoring, the demand for positioning devices is increasing year by year. In addition, with the acceleration of the pace of consumption and the acceleration of market updates, it is gradually becoming more difficult for merchants to grasp the market. Therefore, some merchants hope to integrate positioning devices on their products to accurately obtain the location of use of the goods, so as to grasp more accurately The market can also promptly recycle obsolete commodities. [0003] At present, most of the positioning devices on the market use GSM network communication, GPS and G...
