Problems solved by technology
[0004] (1) When using a pointer pressure gauge to measure pressure, the installation is complicated, the measurement accuracy is low, and the pressure range can only be judged by the measurement or test personnel based on experience;
[0005] (2) Use an inclinometer to measure the lifting angle of the cargo compartment, which is not easy for the measuring or testing personnel to operate, and the error is large;
[0006] (3) It is impossible to effectively measure the rollover angle of the cargo compartment, and it can only be judged by the visual observation and experience of the measuring or testing personnel;
[0007] (4) Hydraulic lifting data cannot be collected synchronously, making data collection difficult and time-consuming

The invention provides a data acquiring system used for the hydraulic lifting of a dump truck. The data acquiring system comprises a sensing device, a converting device, a host computer, and a power supply. The sensing device is used for acquiring a pressure signal and an inclination angle signal of the dump truck when dump truck performs hydraulic lifting, and respectively converting the pressuring signal and the inclination angle signal into a serially-outputted digital signal. The converting device is used for converting the serially-outputted digital signal into USB communication data. The host computer is used for receiving the USB communication data and displaying a pressure value and an inclination angle value which correspond to the USB communication data. The power supply is used for supplying power for the sensing device and the converting device. The system of the embodiment of the invention is capable of completing acquisition of multiple hydraulic lifting data, effectively reducing labor cost, and saving time. In addition, the system with convenient manipulation and easy installation increases the convenience and security of experimenters.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a data acquisition system for hydraulic lifting of dump trucks. Background technique [0002] In the performance test and experiment of the dump truck, the data of the hydraulic lift such as the pressure, the lift angle of the cargo compartment, and the roll angle are very important parameters. [0003] In the prior art, the hydraulic lifting data are measured separately, for example, the pressure is measured by a pointer pressure gauge, and the lifting angle of the cargo compartment is measured by an inclinometer. There are following problems in prior art: [0004] (1) When using a pointer pressure gauge to measure pressure, the installation is complicated, the measurement accuracy is low, and the pressure range can only be judged by the measurement or test personnel based on experience; [0005] (2) Use an inclinometer to measure the lifting angle of the carg...
