Abstract: Aiming at the problems of low test efficiency,insufficient intelligent integration and large test error of the existing Vicat apparatus,a multi-position intelligent integrated Vicat apparatus is developed. The multi-position and double-needle test mechanical structure is designed,and the high-precision laser sensor is used to optimize the automatic leveling scheme of the test needle,while avoiding the deformation of the test needle due to free fall. Based on STM32 single chip microcomputer, the test and control scheme of intelligent Vicat apparatus is designed and developed independently. The test shows that the intelligent integrated Vicat apparatus greatly reduces the operation process and realizes the intelligent determination of the initial and final condensation of the multi-position die test. Among them,the maximum relative error coefficient of initial condensation detection is 2. 35%,and the maximum relative error of final condensation detection is 3. 83%. Compared with the ordinary Vicat apparatus,it has a great improvement,which provides a good test effect for the condensation time of slurry.
