The working principle is as follows: normally, the main switch QF1 is closed and the seat is in the folded retracted state. The switch SR1 is used to select an operating mode, operating in mode a when the contacts 1 and 2 are closed, operating in mode B when the contacts 3 and 4 are closed, and operating in mode C when the contacts 5 and 6 are closed.
When the human body induction switch works in the working mode C, the power on and off of the main circuit are directly controlled through the human body induction switch RT1 as a normal use mode. When the seat is operated in the working mode B, the seat is controlled by the additionally arranged 1# time controller in a time control working mode, the switch node SK1 of the 1# time controller is closed in the set opening time, and the main circuit is controlled to be powered on or powered off through the human body induction switch RT 1. When work in operating mode A, for intelligent mode, through ultraviolet sensor ZWX and rain sensor YL monitoring weather condition, when the sun was too big, ultraviolet sensor ZWX supplied power to 5# relay 9, and 5# relay 9's a normally closed switch K5 disconnection, and when the rainwater was too big, rain sensor YL supplied power to 6 # relay 10, and 6# relay 10's a normally closed switch K6 disconnection, at this moment, all can't control the seat and expand. This purpose is in order to make under the canopy area bigger can bear the weight of more to close the use of seat, just can normally control the break-make electricity of main circuit through passing human inductive switch RT1 under the weather normal condition.
The actual climate condition of an external scene is sensed through the ultraviolet sensor ZWX and the rain sensor YL, and when the ultraviolet is too high, the ultraviolet sensor ZWX controls the 5# relay coil to be electrified; when the rainfall is too large, the rainfall sensor YL controls the 6# relay coil to be electrified; when any point of the output of the 5# relay (ultraviolet rays) or the output of the 6# relay (rainfall) is disconnected, the product control circuit is disconnected, and the product cannot be started.
When a human body induction switch RT1 arranged near the seat induces that a person comes near a product, the circuit is automatically closed, and voice playing capable of opening the seat is performed through the voice playing module, so that the consumption of electric energy under long-term power-on is prevented. The forward rotation limit switch SQ1 is in a normally closed state due to seat folding, the 7# relay 11 is not electrified in a normal state, one normally closed switch K7B is in a closed state, a pedestrian presses a start button SB1 after hearing voice prompt, the 1# relay 6 is electrified, one group of normally open switches K1c is closed, meanwhile, one normally open switch K1a is closed to ensure continuous power supply, a start button SB1 is restored to a normally open state after the normally open switch K1a is closed, a main power supply line A5 and a main power supply line B12 supply power to the motor 17 through one group of normally open switches K1c, the motor 17 rotates forwards to drive the linear electric push rod to stretch out, the seat is pushed out, when the seat stretches to a proper position, the forward rotation limit switch SQ1 is changed to the normally open state due to seat unfolding, the 1# relay 6 is powered off, one group of normally open switches K1c is disconnected, meanwhile, one normally open switch K1a is disconnected, the person can sit on the seat to take a rest. When a person sits on the seat, the normally open pressure switch SP1 is triggered, the 2# time relay TIM1 does not supply power to the 4# relay 8, the output of the reverse signal is not triggered, and the seat can be in an extended state all the time. When no person sits on the seat, the normally open pressure switch SP1 cannot be triggered, the 2# time relay TIM1 performs timing, when a person sits on the seat in the timing process, the normally open pressure switch SP1 is triggered, the 2# time relay TIM1 is reset, timing is ended, timing is performed again, after the set time (preferably 30s) passes, namely, no person sits continuously for 30 seconds, the 2# time relay TIM1 supplies power to the 4# relay 8, the 4# relay 8 sends a reversal seat recovery signal, one normally open switch K4 of the 4# relay 8 is closed, due to the fact that the seat is unfolded, the reversal limit switch SQ2 is in a normally closed state, at the moment, the 1# relay 6 is in a power-off state, one normally closed switch K1b of the normally closed switch is kept closed, the 2# relay 7 is powered on, one normally open switch K2a of the normally open switch K2c of the normally open switch is closed, and continuous power supply is guaranteed, main power supply line A5 and main power supply line B12 supply power to motor 17 through a set of normally open switch K2c, motor 17 reversal, drive sharp electric putter shrink, the seat is withdrawed, when the seat is withdrawed to target in place the back, reversal limit switch SQ2 is triggered because of the seat is folding, become normally open state, 2# relay 7 loses the electricity, its a set of normally open switch K2c disconnection, motor 17 stall, the seat is retrieved and is targetting in place and stop. In this process, if the start button SB1 is pressed, since one of the normally closed switches K2b is in an open state during the power on period of the 2# relay 7, the 1# relay 6 cannot be powered, and thus the motor is not short-circuited. The timer counter TOM1 sets a set time (e.g., 3 minutes) and a set number of times (e.g., 3 times), i.e., 3 signals are obtained within 3 minutes, and the signal is just output. When the reverse limit switch SQ2 is turned off every time, the timing counter TOM1 is triggered, if the timing counter TOM1 is not triggered for 3 times in 3 minutes, the timing is cleared after 3 minutes, the timing is restarted when the timing counter TOM1 is triggered for 3 times in the next time, if the timing counter TOM1 is triggered for 3 times in 3 minutes, the seat is judged to be a malicious switch, the timing counter TOM1 supplies power to the 7# relay 11, one normally-closed switch K7b of the 7# relay 11 is turned off, one normally-open switch K7a of the 7# relay is in a closed state, when the reverse limit switch SQ2 is unfolded again, the seat is triggered to be in the closed state, and the fault lamp HL1 is turned on to indicate that a fault exists. At this time, the timer counter TOM1 is locked for a set time (which may be 5 minutes), i.e., the seat is locked for 5 minutes. At this time, the timer counter TOM1 waits for 5 minutes or presses the reset button FW1, and after the 5 minutes arrives or the reset button FW1 is pressed, the timer counter TOM1 is locked and the 7# relay 11 is powered off. The function can prevent malicious switch or accidental touch, and enhance the safety of the product. The switch node SK2 of the 2# time controller TIM1 may be set for a set period of time so as to control the lighting of a night lamp HL1 near the seat, specifically, within the set period of time, when someone sits on the seat, the normally open pressure switch SP1 is triggered, and the 2# time relay TIM1 controls the switch node SK2 thereof to be closed to supply power to the light recognition HL 1.
