In view of the demand for mud performance maintenance and solid control processing equipment automation in solid mineral exploration drilling， research on the small integrated mud non-landing system that has the cyclic treatment process and the development of control equipment have been carried out. The equipment is mainly composed of the transition system， the purification system， the control system and the circulation pipe sink. In order to realize the reflexive control and remote visual control of the transition pump， PID control and internet of things technology are incorporated into the system. Field trial uses show that the operation of the equipment is safe， reliable and stable； the system has high purification efficiency and high degree of automation； what’s more， good results have been achieved in the aspects of technical cost and environmental protection， meeting the requirements of green exploration. The use of automatic intelligent control technology which reduces the site operation personnel and their labor intensity has improved the automation and intelligence of core drilling equipment to some extent， and provides technical support to achieve the goal of core drilling equipment automation and intelligence.
