EHC-3100M System for Electro-Hydraulic Servo Anchoring Testing Machine

EHC-3100M system anchoring testing machine
 
The system is composed of the independently developed EHC-3100M electro-hydraulic servo measurement and control box, GS-82A digital servo valve group and TestMaster 3.0M testing and control software.

Suitable for working together with the hydraulic static anchoring testing machines from testing machine manufacturers, to compose the electro-hydraulic servo anchoring testing machines.

It is also suitable for the detection organizations to deal with the automatization upgrading and reconstruction of their old hydraulic static anchoring testing machines and upgrade them to electro-hydraulic servo anchoring testing machines.
 
  • Our EDC-3100M system is able to implement load and displacement closed-loop control of the anchoring testing machine, and can achieve smoothly switching between the two control modes. It has the features of high control precision, strong adaptability, reliable long-term stability and so on.
  • The system can implement the whole control process from data acquisition, PID computing and Ethernet communication operation to the output control in a short period of time, thus achieve the accurate closed-loop control for the testing machine.
  • All three input channels use the separate 24-bit A/D converter for high-precision data sampling. The effective internal code is up to ± 200,000.
  • Has up to 15 linear compensation and correction function and greatly improve measurement range and measurement accuracy of the sensor.
  • The measurement unit adopts high precision hollow load sensor and guyed displacement sensor.
  • The controller uses Cotex_M3 32-bit high-speed ARM chip as the master chip, has high computing speed and data processing capabilities.
  • Has three analog input channels: one for loading, two extension channels.
  • Has three photoelectric encoder 4 frequency counting input channels. One channel for guyed displacement sensor, two for photoelectric encoders or grating displacement sensors.
  • Has 4 switch input interfaces: can be connected to 4 switches to input signal.
  • One digital servo valve interface: to connect GS-82 digital servo valve.
  • One electromagnetic reversing valve interface: to connect DC24V rapid return oil electromagnetic reversing valve.
  • One overload protection interface (normally closed contact): connect to the oil pump control circuit. Automatically stop oil pump when testing machine is overloaded.
  • Four switch output interfaces: can be connected to 4 intermediate relays.
  • Using the PID control strategy to achieve the load closed loop control, as well as achieving the functions of constant speed loading, load retention and constant speed offloading.
  • Using the PID control strategy to implement the displacement closed loop control, as well as achieving the functions of constant speed displacement and displacement holding.
  • One 100MHz Ethernet communication interface, achieve high-speed data communications with PC. Has the function of real-time data acquisition upload and real-time delivery of control instructions, so as to achieve the purpose of controlling the anchoring testing machine by PC in real-time.
