Based on the analysis of the application area and function of coalbed methane truck-mounted drilling rig,a remote electro-hydraulic control system is developed to improve the automation level of drilling rig and reduce the hidden danger of personnel safety. The system is mainly composed of electro-hydraulic double-control hydraulic valve,camera and remote console. CAN bus communication is used to quickly connect with the electric control system of drilling rig. The control demand and signal type of drilling rig are introduced with the controller as the core in the remote console. The writing method of analog input of handle and PWM signal output of proportional valve in the software design of Co De Sys is described in detail.Construction application shows that the system can realize remote electronic control operation of drilling rig. The response time of proportional valve is less than 0. 8 s. It has high reliability and portability. At the same time,it simplifies the arrangement of long-distance pipeline,makes drillers far away from wellhead,reduces labor intensity and improves construction safety.
