Example Embodiment

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings:

[0015] Such as figure 1 As shown, the online monitoring system of the fan operating state of the present invention has the following two major components: an embedded ARM platform and a ZigBee wireless sensor network. The terminal data acquisition module is divided into temperature acquisition module, transmitter signal acquisition module and communication module. The coordinator node receives the data of each sensor node wirelessly, and transmits the data to the embedded ARM platform in time; the monitoring software written on the embedded ARM platform receives the data and displays, alarms and data storage in real time. Users operate the monitoring software through the keyboard and mouse, view trend graphs, historical data, and set alarm thresholds.

[0016] Such as figure 2 As shown, for the convenience of development, the present invention can select the finished AR...

Abstract

The invention relates to a fan state online monitoring system and method based on an advanced reduced instruction-set computer machine (ARM) and the ZigBee. Online monitoring of the fan operation state is achieved by collecting temperature, vibration parameters, negative pressure and power parameters of a fan. A ZigBee sensor network is used for collecting and transmitting data, and an embedded ARM platform is used for displaying and processing the data. A terminal device of the sensor network is divided into a temperature collection module, a transmitter signal collection module and a communication module. State data collected by the modules are transmitted to a ZigBee coordinator directly or through a router, and the data are transmitted to the embedded ARM platform through the coordinator. Measuring data are read in monitoring software written on the embedded ARM platform, the fan operation state data are displayed through a liquid crystal display (LCD) touch screen, state data and abnormal alarming data are stored through a security digital (SD) card, and a voice frequency module is used for conducting alarming on the operation state exceeding a threshold. The ZigBee sensor network adopts Z-Stack with a protocol stack as TI.

Description

technical field [0001] The invention relates to a new method for on-line monitoring of the running state of a fan, in particular to an ARM embedded system and ZigBee wireless sensor network technology, and belongs to the field of equipment monitoring. Background technique [0002] Fans are widely used in the industrial field. They are responsible for providing fresh air and discharging harmful gases and dust at the same time. It is extremely important to monitor the operating status of fans. The existing fan monitoring methods are relatively backward. The common method is to use smart instruments to measure relevant data and manually inspect and record regularly. The disadvantage of this method is that the monitoring points are scattered and the real-time performance is poor. The monitoring data cannot be directly used for fan fault diagnosis and early warning, and it also consumes a lot of manpower. Another way is to obtain all monitoring data through PLC or data acquisiti...
