Description
Technical field:
The present invention relates to electronic electric equipment technical field, especially a kind of anti-interference comprehensive intelligent controller that is applied to various plumbing, water treatment place gate, pumping plant.
Background technology:
Interference in electrical equipment working environment is serious.The feature of these interference is that frequency is high, amplitude is large, thereby can be easy to the coupling by various distributed capacitance: have again the duration of these interference short, analog control device can escape these with time delay and disturb, and microcomputer device is owing to being synchronously to carry out with higher speed under the strict control of clock.Delay circuit can not be set simply, and this has just increased the seriousness of interference problem, and the emphasis that therefore improves controller reliability is Anti-interference Design.
The phenomenon that the interference source of electric control system is disturbed under actual condition from electric control system, the suffered interference source of system is divided into power supply interference, signals transmission interference, an interference etc.
Intelligent electrical apparatus development, makes Electro Magnetic Compatibility emc become more and more major issue, and electromagnetic interference (EMI) can cause that this type systematic is malfunctioning and misoperation can cause tremendous economic loss.Intelligent electrical apparatus and its protection, supervisory system are responsive digital appliances element in heavy current and high voltage elect magnetic field, and making has become very important factor in these installation electromagnetical antijamming capability equipment design and runnings.
At present, the lifting of water treatment place gate used, location all rely on the positive and negative rotation of a set of gear control threephase asynchronous machine to realize, and have following problem:
Poor reliability, error are large.Because slide rheostat movable end is moving by belt, be easy to be subject to external interference, make sliding end change in location, cause whole lifting process location inaccurate, slide rheostat wearing and tearing are also larger, fragile, in addition, due to the deadweight of gate itself, cause the difference of sluice ascending velocity and decline rate, simply, by a slide rheostat simulation sluice adjustable height, can't resolve the pinpoint problem of gate at all.
Control operation trouble, automaticity is low.When sluice is during in extreme position, slide rheostat end of slide wire is also in marginal position, has lost automatic control ability, only has by manual operation, to control motor and complete sluice location.In addition, some special control requirements, as sluice lock operation, steel cable elasticity adjusting etc. also can only lean on the manual cooperation of two people to complete, and wastes time and energy, and automaticity is low.
Controller poor anti jamming capability.Control system is disturbed and is mainly derived from high-power threephase asynchronous motor Fraquent start, the voltage ripple of power network that stopped process causes and contactor, the closed electromagnetic radiation producing of control button, it is indeterminable that these two kinds of interference sources only depend on hardware circuit, often occurs that display is not worked and electric machine rotation phenomenon out of control.
Summary of the invention:
The object of this invention is to provide a kind of anti-interference comprehensive intelligent controller, it can guarantee the safe and reliable operation of gate Long-distance Control electrical equipment without PLC and upper configuration software, also realized the standardization of controller product, brought great convenience also to debugging, installation, field maintemance and maintenance simultaneously.
