附录A 科技文献摘译 SCM dormant - reduction and improved anti-jamming capability operating mode 1. Principles and Implementation 1.1Timing of unconditional reset With timers, dedicated clock chip or other pulse generators, according to a set time interval reset signal. This method is particularly suitable for monitoring instruments. In actual operation, often with A / D converter sampling the analog input, and then store display. This process very quickly, but in order to stabilize the reading, but an update of data per second or 2 times, CPUs a lot of time to wait. If the CPU to End After the implementation of direct access to dormant, and then reset by an external wake-up call to the implementation of its next operation, which is regularly reset law. This will greatly enhance the anti-interference capabilities, mainly 2:00: ① dormancy, the process stopped running, no PC pointer disorder caused by flying procedures run. If the work and sleep time for the ratio of 1:9, that is, 1 s with 0.1 s time for testing, delivery, a 0.9 s time to sleep, the probability of interference process is running at full speed when the 1 / 10 , The overall anti-disturbance capacity increased by 10 times. ② As per 1 s unconditional reset 1, once a particular work during the Dead, certainly in the next reset to resume. The only show that the instrument, a 1 s occasional readings of the next measurement error and no memory, it can bear, is a one-off mistake. This time reduction relative to the merits of the watchdog circuit, to wait for the first time to sleep, shortening the time may be affected by interference and the other is just to avoid a watchdog controlled areas include the death cycle. 1.2 Reduction of external conditions Some measure of output or is activated by external control. Heating table such as heat, hot water Shuilun rotation on the pulse calculated heat, no hot water flows, there is no heat output, CPU as long as you maintain the original values, do not count. Imagine stopping
