Conventional operation parameter monitoring device for construction machineries can only achieve sound (or light) alarm and control over over-limit status for operation parameters of construction machinery and it can not save any historical data, thus hinders accurate analysis, diagnosis and maintenance of the construction machinery. The operation parameter recorder for construction machinery developed based on industrial control computer and embedded technology can detect, record and manage the operation parameters. The real time fault alarm and historical data analysis can also be realized. The industrial computer, which is core module of this operation parameter recorder, controls the operation parameter acquisition module based on micro-controller ARMSTM32F103 to acquire and condition each operation parameter of the construction machinery. Application software running on the industrial computer processes the operation parameters and carries out alarm and control operations under abnormal conditions for fault protection. The abnormal data shall then be stored for later fault analysis. This operation parameter recorder can record many different types of operation data and has a large storage capacity, so it is applicable to many different types of construction machinery.
