Outdoor advertising safety detection method based on ZigBee and MEMS (micro-electromechanical system) sensor

Abstract

The invention discloses an outdoor advertising safety detection method based on ZigBee and an MEMS (micro-electromechanical system) sensor. The method is mainly used for judging the safety state of the current outdoor advertising with a node attitude inclination contrastive analysis method and producing early warning for hazardous conditions. A system can be mainly divided into a sensor acquisition subsystem, a wireless sensor network system and a terminal monitoring platform. In order to improve monitoring range and measuring precision of the system and reduce power consumption and cost of the system network, a ZigBee wireless network is adopted to build a network platform, and a six-axis sensor data fusion algorithm technology is combined, so that multi-point monitoring and high-precision measurement of outdoor advertising equipment are realized; the terminal monitoring platform utilizes an ARM processor as an intelligent control core, application programs operate on a Linux operating system, data can be processed and analyzed with high efficiency in a multi-thread mode, and early warning information can be sent out and transmitted to a remote server with a GPRS (general packet radio service) technology.

Description

technical field [0001] The invention belongs to the field of non-network monitoring, and in particular relates to an outdoor advertisement safety detection method based on ZigBee and MEMS sensors. Background technique [0002] Nowadays, large-scale outdoor advertising equipment is widely used in cities and along major traffic roads, and its popularity continues to increase. However, due to its large size, it is placed in an outdoor environment for a long time, and is affected by wind and rain, aging and corrosion, and there are potential safety hazards. If it is weak, it will be tilted or even dumped, which will cause unpredictable loss of life and property. [0003] At present, the monitoring method of most outdoor advertising equipment in China is to rely on the staff of relevant departments to conduct on-site inspection through visual inspection or simple equipment; , passively waiting for the accident to happen. However, the above two methods often have defects such as...

However, due to its large size, it has been placed in the outdoor environment for a long time, and is affected by wind and rain, aging and corrosion, and there are potential safety hazards. If it is weak, it will be tilted or even dumped, which will cause unpredictable loss of life and property.

[0003] At present, the monitoring method of most outdoor advertising equipment in China is to rely on the staff of relevant departments to conduct on-site inspection through visual inspection or simple equipment; , passively waiting for the accident to occur

However, the above two methods often have defects such as insufficient measurement accuracy, limited range, and inability to effectively detect potential threats.
