Embedded system on-line debugging emulation method based on communication interruption

The invention relates to an online debugging simulation method for an embedded system based on interruption communication, which is characterized in that: when a user program which is operating is hung, a debugging host computer can send an interrupt signal and an instruction ready for debugging; after the embedded system responses, the program index of a stack and the breakpoint spot information of the user program are saved, the program index of the stack is modified as an entry address of a closed loop of a monitoring communication interface, and the stack at operation state is set at debugged state and returns to the closed loop; when the operation of a user program needs to be resumed, the debugging host computer send an interrupt signal and an instruction ready for operating the user program; after the embedded system responses, the saved program index and the breakpoint spot information of the user program are resaved into a corresponding stack position, and the stack resumes the breakpoint spot of the user program and returns to the position where the user program is hung for further operation. The online debugging simulation method for the embedded system based on interruption communication can realize online debugging simulation without extra hardware and occupies small sources.

Method and device for monitoring the integrity of a connection system

A device is configured to monitor the integrity of a connection system between first and second fluid containing systems comprising first and second pulse generators. A pressure sensor is arranged in the first fluid containing system to detect first pulses originating from the first pulse generator and second pulses originating from the second pulse generator. The device operates a monitoring method, by generating (42) a time-dependent pressure signal based on measurement data obtained from the pressure sensor such that the pressure signal contains a sequence of apparent pulses. The apparent pulses represent a superposition of the second pulses on the first pulses when the connection system (C) is intact. The device processes (44) the pressure signal to calculate a parameter value based on a pulse feature of at least one of the apparent pulses in the pressure signal. The parameter value represents a disturbance caused by the superposition of the second pulses on the first pulses, and may be given as a measure of statistical dispersion, pulse-to-pulse symmetry, or first pulse similarity. The device determines (45) the integrity of the connection system based at least partly on the parameter value. The first fluid containing system may be an extracorporeal blood circuit, and the second fluid containing system may be a human or animal subject.
