The invention provides a near-end and remote full-process control system for a cementing unit, at least comprising a remote operation control system and a local operation control system connected by an Ethernet, wherein the remote operation control system at least comprises a PLC remote controller and a remote human-machine interface connected thereto, and the local operation control system at least comprises a PLC local controller and a local human-machine interface connected thereto; the PLC local controller is connected to and controls the mud mixing system, the hydraulic system, the air circuit system, the pumping system and other monitoring systems, respectively. The near-end and remote control system of the invention provides more operation options for the cementing unit, the two systems back up and are independent of each other, ensuring that when a certain control system fails, the system can be switched to achieve normal operation. The reliability of the cementing unit is improved.
