The Design Of A Monitoring System For Excavator

With the high speed development of our country's economy, infrastructure projects quantities has been increasing rapidly, the demand for construction machinery has been growing accordingly. As a result of the high price of construction machinery, currently, the mainly way of selling is finance leases, and many rental companies launched construction machinery rental business, thus bringing a series of problems, such as purchaser didn't repay to vendors on time, renter damaged the rental machinery deliberately, maintenance was not convenient and the widespread "scoop up fuel" problem.Therefore, mechanical engineering combined with remote monitoring technology becomes a inevitable trend of engineering machinery development.In this paper, single-bucket excavator as the research object, and a remote monitoring system was designed in this paper. The design work was introduced in detail:The excavators operating parameters, such as hydraulic oil temperature, inlet oil pressure, flow, tank liquid level and working hours, were collected by the host MCU; GPS positioning module was used to get the excavator location and speed; GPRS module was adopted to send point to point short message to upload the excavator working state parameters to the monitoring center regularly.GPRS module was used to receive the short message uploaded by terminals, and then the information was analyzed according to the agreed protocol automatically; the visual development language VB was adopted, and Microsoft MSComm control was used to receive, analyze and display the excavator operating parameters. When the operating parameters were abnormal, monitoring system can send alarm message to the terminal to get timely equipment maintenance; meanwhile, a check instruction can be sent to get the latest working parameters. In addition, the widespread "scoop up fuel" problem can be prevented effectively by fuel analysis.
