Abstract

The invention discloses a precision current detection apparatus of an NB-IOT terminal under multiple operation modes. The apparatus comprises an overall scheduling unit, a radio frequency unit, a base-band signal generating unit, a base-band signal processing unit, a combiner, a synchronous processing unit, a high speed AD conversion unit, a multi-range galvanometer and a voltage output unit. The radio frequency unit comprises a radio frequency emission unit and a radio frequency receiving unit. The apparatus is integrally designed with a power supply current through a protocol stack and accurate current measurement to an NB-IOT module at any moments is realized so that a current measurement problem of a time-varying system is solved and dynamic current measurement at a microsecond grade can be realized, a measured speed is fast and good synchronization is possessed. Besides, the apparatus possesses a good cost performance, the size is small and weight is light. Compared to a traditional measurement system, usage convenience of the apparatus is greatly increased. Under signaling mode measurement, without any external design, whole measurement can be completed so that measurement efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of current detection, in particular to a precision current detection device in multiple working modes of an NB-IOT terminal. Background technique [0002] The cellular-based Narrow Band Internet of Things (NB-IOT) has become an important branch of the Internet of Everything. NB-IOT is built on a cellular network and only consumes about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. [0003] NB-IOT is an emerging technology in the field of IOT, which supports the cellular data connection of low-power devices in the wide area network, also known as low-power wide area network (LPWA). NB-IOT supports efficient connection of devices with long standby time and high network connection requirements. It is said that the battery life of NB-IOT devices can be increased to at least 10 years, while also providing ve...
