Electrification reset generally mainly uses both of which, and first plays reset using the charge and discharge of RC circuit, and second uses
Timing reset chip plays reset, and this reset mode generally can only all power on the reset played constantly to veneer, once it is electric
After pressure is stablized, which can not just play reset function.Electrification reset mode, which only can be used in, powers on the moment, very big using having
Limitation.
2. system general reset mode
The common method of system general reset mode is other veneers in the acquisition systems such as the master control borad such as CPU in system
The data etc. that operating status or judgement are sent, if master control borad determines veneer run-time error, i.e., into signal system other
Veneer sends reset command, once this mode CPU sends reset command, all veneers in system will all be reset, and is
System is just unable to operate normally.
3. hand-reset
Hand-reset mode often goes manually to participate in system reset according to system running state instruction, this mode can be real
Existing veneer individually resets, but needs manually ceaselessly to pay attention to operating condition, expends a large amount of manpowers, and in the interlocking of the machine of calculation, vehicle
The special application places such as automatic train protection system are carried to require to avoid artificial excessive participation.

The device of reset, including one piece of master control borad and several pieces of veneers coupled with the master control board communications, every piece of veneer is equipped with a ratio
Compared with circuit, whether the reseting address for judging that master control borad is sent is identical with the veneer, and every piece of veneer sends operating status in real time
To master control borad, master control borad judges the operating status of every piece of veneer to select board resetting mode, if master control borad detects
To great run-time error occurs, master control borad sends general reset signal, resets all veneers, if master control borad detect only certain
Block veneer run-time error, then master control borad sends the veneer address that needs to be reset, the reseting address and veneer sent when master control borad
When location is identical, which is reset.
Preferably, the comparison circuit on every piece of veneer is by the pull-up of backboard or the slot position of drop-down every piece of veneer of setting
Location, by the way that slot position address and master control borad are issued the comparison of board resetting address signal, when the two is identical, comparison circuit can be generated
One low level signal is used for board resetting.
Preferably, the great run-time error includes that data are obstructed between veneer and master control borad, veneer is uncontrolled.
