Abstract： In order to solve problems such as multi tests in different environments, kinds of testing methods and the amounts of data in construction machine hydraulic system, a way suitable for different construction hydraulic system testing platforms is put forward. The testing-control system has the advantages such as the modularization, multi-interface and all-purpose way, and is divided to host-low structure, can accomplish 40 channel signal’s control and acquisition; the testing-control platform can set about 80 kinds of experiments in different working conditions. Through debugging operation, the system runs very well and reliable.
