Embodiment 1

[0023] This type of wireless acceleration sensor is developed to meet the vibration monitoring needs of industrial machines, pumps and equipment in related industries. Compared with indoor environmental monitoring, civil engineering monitoring, and agricultural monitoring, the vibration monitoring of industrial machines and pumps has the characteristics of larger data volume, higher data real-time and accuracy requirements, and greater power consumption. Constrained by the installation conditions of industrial sites and various dangerous working conditions, wireless sensors can only be powered by batteries with limited energy, which limits the power consumption level and computing power of sensors, and brings great challenges to the design. The present invention will solve the above-mentioned problems from the following several specific implementation modes.

[0024]The first is the design of the wireless acceleration sensor software system. The software system adopting hiera...

Abstract

The invention relates to a wireless acceleration sensor for vibration monitoring. The wireless acceleration sensor, which includes two parts: hardware and software, is characterized in that: the hardware comprises a control circuit board, a sensor housing, a piezoelectric acceleration sensor, a strength magnetic seat, a lithium battery set and an antenna; and the software programming employs a layered design and the software is divided into a network layer, a media access control layer and a physical layer. According to the above-mentioned design scheme in the invention, the sensor has characteristics of lightweight structure and convenient assembling; and it is easy to realize mass production and large-scale layout. And utilization of the software system design enables power consumption of the sensor to be substantially reduced and service life of the sensor to be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of sensors, in particular to a wireless acceleration sensor for vibration monitoring. 【Background technique】 [0002] In today's increasingly competitive market, companies face increasingly severe challenges to improve process efficiency, comply with environmental regulations and meet their own economic interests. Considering the aging of many industrial systems, as well as the dynamic changes in the industrial market, there is an urgent need for intelligent, low-cost industrial automation systems to improve the efficiency and productivity of these systems. Traditional industrial automation systems rely on cable connections to do so. However, wired automation systems require the installation of expensive communication lines and require regular maintenance. Therefore, wired automation systems have not been widely used in industry. Therefore, there is an urgent need for a low-cost wireless automation syst...
