Type type of message, defines as follows:
The instruction of code position code is as follows:
Wherein, power is power supply, and PCIBus is bus, and pausekey is intervalometer, and BIOS is basic input output system.
Daily record storage mode adopts from the past record next time of the head of every one page, when recorded the second from the bottom of each page, start after having recorded to wipe lower one page, so can search the position of the last item record when mainboard start next time definitely, otherwise be likely to result in false judgment.As it is shown in figure 5, recordable 15 of each page, after recorded the 14th of page 1 article, wipe page 2.Due to the restriction of storage size, logout cannot store too much, adopts and record is carried out classified statistic, then final statistical information is sent to host computer.Statistical information definition is as follows:
Step 414, enables house dog, carries out feeding Canis familiaris L..
Concrete, house dog and watchdogtimer, be a timer circuit, generally having an input, cry and feed Canis familiaris L., the RST end of microcontroller is arrived in an output, when microcontroller normal operation, one signal of output is to feeding Canis familiaris L. end at set intervals, to watchdog zero clearing, if it exceeds the scheduled time does not feed Canis familiaris L., house dog timing exceedes, a reset signal will be provided to microcontroller, make microcontroller reset, it is prevented that microcontroller crashes.
Step 416, the mode of operation of detection mainboard.
Step 418, if the mode of operation of mainboard is normal condition, then processes the message of reception, then returnes to step 414.
Step 420, if the mode of operation of mainboard is under-voltage state, then processes according to under-voltage state, then returnes to step 414.
Concrete, under-voltage state carries out processing namely processing according to step 202 to step 218, does not repeat them here.
Additionally, when external interrupt produces, perform step 430: the mode of operation of mainboard switches to under-voltage state, then log, and enter the step of step 416 mode of operation detection.
Above-mentioned industrial device controls processing method, by when the system is first powered on, initializes mainboard, and whether detection mainboard starts, if not actuated log, then adopts under-voltage state to process, it is ensured that the normal startup of mainboard.
In one embodiment, when the mode of operation of mainboard is normal condition, processes the message received, specifically include: the message received is verified, if verification is passed through, then perform this message.
