A controller for a pallet of a cement prefabricated part comprises an ARM 7 controller, a power supply module, a communication interface module, an A / D conversion module, a frequency converter, an output reactor, a frequency variable motor M1, a frequency variable motor M2, a digital interface module and a stop signal sensor. The ARM 7 controller is connected with peripheral equipment via the interface module, collects external signals, carries out operation, controls output of the frequency converter via the A / D conversion module, and controls motion of the pallet; a programming tool downloads a compiled final-version control program which passes testing into a program memory of the ARM7 controller; and a memory is an ROM, and capable of multitime erasing and power-down protection. According to the invention, an embedded single-chip microcomputer serves as the controller, the pallet operates stably and reliably, the production efficiency is improved, the cost is reduced, maintenance is convenient, and the controller is applied to the technical field of automatic control of cement machinery.
