[Abstract]:The key control techniques of gravity chip processor are logic action control, real-time dynamic alarm mechanism and chip temperature control. The processing capacity of the gravity chip processor is restricted by the logic action of the executing mechanism, alarm release, chip heating time and heating accuracy. It is difficult to realize the logic action control because of the large number of actuators and complicated process. The rationality of alarm mechanism determines the JAM rate (failure rate) of processor, and in the process of chip temperature heating control, there are many kinds and number of controlled objects. The main reasons for the high efficiency of the gravity chip processor are that the controller control parameter setting takes time and effort, the temperature heating time is long, the overshoot is large, and the temperature inside the chip can not be measured directly, which also affects the high efficiency of the gravity chip processor. According to the structure of gravity chip processor and the flow process of the chip, the logical action control of the executive mechanism of each branch is designed, and the whole operation process of the chip to be tested from input to sorting and receiving is completed. The dynamic alarm system is designed by using controller, configuration interface and real-time database. The functions of recording alarm information, dynamic real-time alarm query, historical alarm data query and conditional alarm query are realized. The man-machine interface is designed to realize the visualization of the running state of the gravity chip processor and to collect the corresponding information and data. The chip heating is controlled by multi-stage heating and piecewise temperature compensation to complete the heating process from normal temperature to test temperature. In order to speed up the dynamic response of the system, shorten the temperature adjustment time and restrain the temperature overshoot, the controller parameters are complicated and complicated. A control algorithm based on relay feedback is proposed, which combines parameter self-tuning and dynamic integral separation. The mathematical model of the controlled object is obtained by system identification. On this basis, the algorithm is theoretically verified by simulation. Finally, the validity and rationality of the algorithm are further verified by the actual heating test of the gravity chip processor. With the application of gravity chip processor, reasonable chip flow control strategy and alarm mechanism are designed to ensure the efficiency and rapidity of the processor. The actual test data show that the average daily processing capacity of the processor is 28000. The average JAM rate was less than 0.5 鈥，
