Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
A kind of hydraulic system testing recorder of the present invention, this testing recorder comprises high-speed data puocessing module, signal input output interface, USB interface and upper-position unit; Described high-speed data puocessing module is for the treatment of the sensor information of hydraulic system or hydrovalve information; Described signal input output interface is used for receiving or sending sensor information or hydrovalve information; Hydrostatic sensor group and hydraulic valve bank are by corresponding sensor information and the paramount logarithmic data puocessing module of hydrovalve information transmission; Described high-speed data puocessing module is connected with upper by USB interface; Described upper-position unit contains data processing and scoring system software, for carrying out analytic record to the signal of hydraulic system and show, or under to send instructions paramount fast data processing module.
Hydraulic system testing recorder also comprises hydrostatic sensor group, and described hydrostatic sensor group is connected with high-speed data puocessing module by signal input output interface.If hydraulic system does not possess online hydrostatic sensor, then the sensor that testing recorder can be utilized to carry is tested.
Signal input output interface can also according to circumstances optionally be connected with other peripheral control units, receives the information that other peripheral control units send, or sends information to other peripheral control units.
As shown in Figure 1, signal input output interface, specifically comprises signal input module and signal output module to a kind of hydraulic system testing recorder.Hydraulic system signal source 5 and signal each plug of coming in and going out in module 3 is corresponding to be connected; Wherein, PLC signal correspondence is connected to signal and comes in and goes out on the Proportional valve of module, servovalve plug; The corresponding information of hydraulic system signal source collection also transfers to high-speed data puocessing module 1 by signal input module; Simultaneously high-speed data puocessing module by USB interface 7 by related data transmission to upper-position unit 8, shown by the data processing in upper-position unit and scoring system software, record, upper-position unit can also send instructions down paramount fast data processing module; Signal output module 2 is connected with hydraulic valve bank 9 and other control system (PLC control system); Related data is transferred to hydraulic valve bank and other control system by signal output module by high-speed data puocessing module.
