Abstract
The invention discloses a wiping frequency adjustable wiper control system, which is characterized in that: A and B transfer two signals to an end angle 2 and an end angle 6 of a singlechip U1; through comparison of signal receiving time, whether the signals are frequency increasing signals or frequency reducing signals is determined; if the wiping frequency is to be increased, the interval of control signals is shortened; and otherwise, if the wiping frequency is to be reduced, the interval of the control signals is increased. The control signals are output through I to control a wiper motor. Through the setting, the singlechip of the wiper control system judges to increase or reduce the wiping frequency or not according to the received signals so as to adjust the wiping frequency of a wiper.
Description
Technical field
The present invention relates to the vehicle rain blowing controlled system.
Background technology
Present wiper is generally soon, slow, 3 gears intermittently, but actual use often can't be satisfied user demand, rainfall and the unmatched phenomenon of wiper speed appear, realize by the capacitor charge and discharge time off time of gap shelves, some band adjustable frequency windscreen wiper only is to increase a potential device (variable resistance) to realize that regulating effect is relatively poor.New-type control system is not used electric capacity but is directly adopted Single-chip Controlling, and the wiper frequency of windscreen wiper can freely be adjusted fully, has broken through the restriction of static stall, and is more convenient and practical.
Summary of the invention
The objective of the invention is freely to adjust, and realize regulating by the code-disc knob for the wiper frequency users that makes windscreen wiper.
In order to realize above purpose, the present invention program is: the wiper frequency of setting an acquiescence, work by this frequency behind each unlatching windscreen wiper, this moment, the user can regulate code-disc knob or button up and down as required, after signal passes to micro controller system, micro controller system judges that according to the signal that receives increase still reduces the wiper frequency, thereby realizes the adjustment of the wiper frequency of windscreen wiper.
Description of drawings
Fig. 1 is the combined switch control chart
Fig. 2 is wiper controller figure
The specific embodiment
As shown in Figure 1, 2, A, B import 2, the 6 end angles of two signals to micro controller system U1 into, through receiving the contrast of signal time, determine that it still is that frequency reduces signal that frequency increases signal.If it is will increase the pitch time that the wiper frequency is then dwindled control signal, opposite if reduce the pitch time that the wiper frequency then increases control signal.Control signal is controlled rain shaving electrical machine by I output.
The short rain shaving electrical machine low speed end that connects of low speed coil 53M, anode 15 connects the car load power supply, and A connects code-disc A terminal, and B connects code-disc B terminal, and A, B terminal are used for obtaining signal and judge that increase still reduces the wiper frequency.Intermittently I connects control end in the combined switch shelves at intermittence, and the return signal connects rain shaving electrical machine return terminal, and battery cathode connects the car load bonding.
When opening washing, windscreen wiper intermittent duty relay T terminal is by combined switch B5-B3 electric shock bonding, windscreen wiper intermittent duty relay inside chip U1 the 5th stitch obtains a low level, by logic operation chip U1 the 3rd stitch output high trigger pulses, thereby aerotron Q4, the Q5 triggering and conducting, coil 4-5 gets, switch 1-3 conducting, after chip U1 becomes low level after the triggering and conducting, Q4, Q5 closes, coil 4-5 outage, switch 1-2 connects, and 53M and 53S form path this moment, and the 53S end passes through rain shaving electrical machine inner structure bonding in the course of the work, thereby make the rain shaving electrical machine two ends keep electric potential difference to guarantee the normal operation of rain shaving electrical machine, when rain shaving electrical machine work to the return position, promptly during initial condition, the contact by the inner return sheet of rain shaving electrical machine connects, 53S is a high level, and rain shaving electrical machine two ends electric potential difference is that 0 motor quits work.This working process is a circulation.
When combined switch is beaten to shelves intermittently,, windscreen wiper intermittent duty relay I end is low level thereby connecting bonding end I end by combined switch inner contact B6-B3.Chip U1 controls the 3rd stitch and exports trigging pulse with original frequency, the control rain shaving electrical machine is with original frequency work, when on the rotation combination switch during control button, chip obtains signal by A, B terminal on the combined switch and judges that increasing the wiper frequency still reduces the wiper frequency, thereby adjusts the width of U1 the 3rd stitch end output trigging pulse.Realize the adjustment of rain shaving electrical machine wiper frequency.
