Abstract

The invention relates to a digital interphone for an intelligent standing and falling detection monitoring system. An interphone circuit mainly comprises a standing and falling detection module, a data processing module, an information storage module, a display unit module, a global positioning system (GPS) module and a data transmission module, wherein the standing and falling detection module mainly comprises a CMA3000 acceleration sensor of VastView technologies Inc. (VTI) and a signal output port; when a three-axis component of the CMA3000 acceleration sensor is changed, an interrupt signal is generated to notify the data processing module; and the data processing module acquires the three-axis component of the CMA3000 acceleration sensor of the VTI in the standing and falling detection module through a serial peripheral interface (SPI) bus, and judges the standing and falling state of the interphone according to threshold value data. The digital interphone adopts a digital private mobile ratio (DPMR) standard, and has the special performance of high anti-interference capability, high quality, long transmission distance, high confidentiality, high reliability, highly-flexible service adaptability and external interface connecting capability, and the like.

Description

technical field [0001] The invention relates to an intelligent leveling detection and monitoring system, in particular to a digital walkie-talkie used in the intelligent leveling detection and monitoring system. Background technique [0002] The walkie-talkie is a two-way mobile communication tool. It can make calls without any network support, and there is no call charge. It is suitable for relatively fixed and frequent calls. The functions of today's walkie-talkies have been developed towards practicality and specialization. Various functions have been realized on walkie-talkies. They are mainly used in public security, civil aviation, transportation, water conservancy, railways, manufacturing, construction, service and other industries. Communication and command dispatch among group members to improve communication efficiency and improve the rapid response ability to deal with emergencies. [0003] The digital walkie-talkies launched on the market can realize functions s...
