The control setup that above-mentioned parking signal apparatus intelligence control system is adopted, its principle of work is following:
Adopt annunciator as stop signal, annunciator is contained on the transmission shaft, gets annunciator during parking.When the driver was stopped and to be opened the door, trigger switch after MCU receives instruction, was put the current demand signal memorial tablet and to be judged that magnetic coder provides location information, makes the open position that logic determines commander drive motor turns to annunciator expectation then.The driver is closed behind the door, and switch breaks off, and the revolution of MCU commander drive motor is returned to former off position up to annunciator.
Concrete mode of operation is following:
After powering on, annunciator is got back to off position automatically; MCU reads the output of magnetic coder, stores this location information;
After the switch triggering, the MCU judgement needs mobile direction and angle, and drive motor rotates and makes annunciator be positioned 90 ° ± 5 ° open position;
After switch broke off, MCU commander drive motor made annunciator get back to 0 ° of make position, and the subsequent drive that 750MS arranged is to guarantee near 0 °;
In reading the process of annunciator, if run into obstacle, MCU can increase the rotation time to 15 second (open mode) of drive motor, 0.75 second (closed condition);
Receiving artificially when stirring annunciator, MCU can judge new position, and commander's drive motor is sent annunciator back to tram (90 ° ± 5 °);
Under the state that annunciator is opened, indicator lamp is in blink states, frequency adjustable;
When not moving for a long time, MCU gets into low power consumpting state automatically and saves battery electric quantity.
Beneficial effect of the present invention is:
Based on the intelligent closed loop control of microcontroller, adopt magnetic coder that the position of signal arm is accurately indicated, logic determines is very capable, the various accidents that occur in the ability work of treatment process.Intelligent controller adopts hermetically sealed design, adapts to abominable external environment.Big electric current and small-signal coexist as in the same circuit card, adopt the design of light current control forceful electric power, and antijamming capability is strong.Have surge protection, the power supply reverse connecting protection, the self check of working sensor state, the back system failure prevents to lose efficacy.Adopt intelligent electric power management, be in the dormancy low power consumpting state in off working state.
