Embodiment Construction

[0012] The above is the content of the technical solution of the present invention, and now the solution of the present invention is described in detail as follows through the embodiments:

[0013] A new type of work-hour monitoring method disclosed in this embodiment is to install a flow meter on the oil inlet pipe of the vehicle, connect the flow meter to a single-chip microcomputer, process the data returned by the flow meter through the single-chip microcomputer, and judge the state of the engine according to the fluctuation of the instantaneous flow data. When the machine is stopped, the instantaneous fuel consumption is 0; when it is in standby, the instantaneous fuel consumption is very stable with little fluctuation, and when the construction machinery is working, the instantaneous fuel consumption fluctuates greatly; use this principle to calculate the working hours, specifically by calculating the variance of fuel consumption to judge, the specific calculation formula ...

Abstract

The invention discloses a novel man-hour monitoring method. By utilizing a principle that required instantaneous fuel consumption data is different since an engine has different works under differentstates, the instantaneous fuel consumption is zero when engineering machinery is in downtime; the instantaneous fuel consumption is extremely stable and the fluctuation is small when the engineering machinery is standby; and the instantaneous fuel consumption is large in fluctuation when the engineering machinery is at work. By utilizing the principle, a working state of the engineering machineryis judged by computing a fluctuation variance yield of the instantaneous fuel consumption, and the monitoring precision is improved; a man-hour monitoring way of the monitoring method disclosed by theinvention cannot be affected by external factors, and is high in reliability and suitable for the engineering machinery such as an excavator, a loader, a bulldozer, a crane and like different varieties.

Description

technical field [0001] The invention relates to the field of working hours monitoring, in particular to a novel working hours monitoring method. Background technique [0002] At present, there are two mainstream monitoring methods for the working hours of construction machinery. One is to use the method of monitoring voltage. When the vehicle is ignited, the generator works when the construction machinery starts, and the output voltage is high. When it is not started, it is the battery. Voltage, the voltage is low, this method intelligently monitors the start and stop of the engine, that is, it can only distinguish the stop state from the start state. [0003] The other is to use a vibration sensor to monitor, using the vibration frequency and amplitude of the vibration sensor to monitor the working, standby and shutdown states of the construction machinery. This method is easily disturbed by external factors. If there are other vibration sources, the sensor will be damaged....
