in order to prevent other power supplies for supplying power to the voice prompter 5 and the human body detection system 6 from being connected in series with other circuits of the school bus safety device to affect power saving, the voice prompter 5 and the human body detection system 6 are generally multipurpose, so that in the invention, a power supply output forward string diode D1 of the power switch control module 10 is connected with a power supply input end of the voice prompter 5, and a power supply output forward string diode D2 of the power switch control module 10 is connected with a power supply input end of the human body detection system 6.
as shown in fig. 3, the power switch control module 10 for the school bus man-machine combination monitoring device to save power supply includes: the circuit comprises an OR gate 11, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a first switch tube T1, a second switch tube T2, a silicon controlled rectifier SCR, a diode D3, a relay J, a capacitor C1 and a capacitor C2; the positive pole of the power supply 20 is connected with the normally open contact of the relay J in series and then is output OUT of the power switch control module 10; the output OUT of the power switch control module 10 is connected in series with the capacitor C1 and then is connected to the negative electrode of the power supply 20; the power supply input end of the OR gate 11 is connected with the anode of the power supply 20, and the power supply cathode of the OR gate 11 is connected with the cathode of the power supply 20; one input end of the OR gate 11 is connected with a trigger power supply starting control signal output end additionally arranged on the ignition switch detector 2, and the other input end of the OR gate 11 is connected with a trigger power supply starting control signal output end additionally arranged on the vehicle door state detector 3; the output end of the or gate 11 is connected in series with the resistor R3 and then connected with the base of the first switch tube T1, the base of the first switch tube T1 is connected in series with the resistor R4 and then connected with the negative electrode of the power supply 20, and the emitter of the first switch tube T1 is connected with the negative electrode of the power supply 20; one end of a resistor R1 is connected with the anode of the power supply 20, the other end of the resistor R1 is connected with one end of a capacitor C1 and the collector of a first switch tube T1 in parallel, the other end of the capacitor C1 is connected with one end of a resistor R2 and the control end (grid) of a Silicon Controlled Rectifier (SCR) in parallel, the other end of a resistor R2 and the cathode of the Silicon Controlled Rectifier (SCR) are connected with the cathode of the power supply 20, the anode of the Silicon Controlled Rectifier (SCR) is connected with the anode of the power supply 20 after being connected with a relay J coil in series, and a diode D3 for follow current is connected; one end of the resistor R5 is connected with a trigger power supply closing control signal output end additionally arranged on the monitoring controller 1, the other end of the resistor R5 is connected with one end of the resistor R6 and the base electrode of the second switch tube T2 in parallel, the other end of the resistor R6 and the emitter electrode of the second switch tube T2 are connected with the negative electrode of the power supply 20, and the collector electrode of the second switch tube T2 is connected with the anode of the SCR.
The capacitor C2 is used to ensure that the power output of the power switch control module 10 disappears after a proper delay after the relay J is disconnected, which is beneficial to effectively cutting off the power supply.
And the SCR is a one-way SCR and is used for triggering and keeping the J coil of the relay to be electrified.
the or gate 11 is a two-input or gate, that is, when both input ends input a low level, its output end outputs a low level, otherwise, its output end outputs a high level. Two input ends of the or gate 11 are two input control ends of the power switch control module 10 for triggering to be turned on respectively.
When the output of the or gate 11 changes from high level output to low level output, the first switch tube T1 changes from on saturation to off, the power supply 20 generates an effective trigger control signal to the control end (gate) of the silicon controlled SCR through the resistor R1 and the capacitor C2, the silicon controlled SCR is triggered to turn on, the relay J coil is energized, after the capacitor C2 is full, the trigger control signal of the silicon controlled SCR disappears, and at this time, when the or gate 11 keeps outputting low level, the power supply 20 sends no trigger control signal to the control end (gate) of the silicon controlled SCR through the resistor R1 and the capacitor C2.
when the output of the or gate 11 changes from low level output to high level output, the first switch tube T1 changes from off to on saturation, the capacitor C2 forms a discharge loop through the first switch tube T1 and the resistor R2, and the capacitor C2 discharges, so as to: when the or gate 11 outputs a low level again, the first switch tube T1 is turned from on saturation to off, and the power supply 20 generates a trigger control signal to the control terminal (gate) of the SCR through the resistor R1 and the capacitor C2, so as to meet the requirement of the control signal for triggering and turning on the SCR. Because the negative voltage is formed on the resistor R2 in the discharging process of the capacitor C2, an effective trigger signal cannot be generated on the SCR. And because the first switch tube T1 that is turned on plays a clamping role, no trigger signal (so to speak, no effective trigger signal) is sent to the control end (gate) of the SCR after the capacitor C2 finishes discharging.
due to the effect of the capacitor C2 during the low level output period of the or gate 11, i.e. the off period of the first switch transistor T1, a valid trigger signal is generated to trigger the SCR to turn on, and when the capacitor C2 is full, no trigger signal (so to speak, no valid trigger signal) is sent to the control terminal (gate) of the SCR.
During the high level output period of the or gate 11, i.e. during the saturation conduction period of the first switch tube T1, no effective trigger signal is sent to the SCR control terminal (gate) during the discharge process of the capacitor C2, and the conducted first switch tube T1 plays a clamping role, so that no effective trigger signal is sent to the SCR control terminal (gate) after the capacitor C2 discharges.
And when the conducted silicon controlled rectifier SCR has no trigger signal, controlling the current of the conducted silicon controlled rectifier SCR to be smaller than the maintaining current, and conducting the silicon controlled rectifier SCR to be disconnected. The second switch tube T2 is turned off, and the current passing through the SCR is not affected. The second switch tube T2 is in conduction saturation, the voltage drop is only about 0.3V, and the conduction voltage drop of the thyristor SCR is greater than 1V, so that the conduction thyristor SCR is turned off.
The SCR is switched on, the coil of the relay J is switched on, the normally open contact of the relay J is switched on, and the power supply 20 reaches the output OUT through the normally open contact switched on by the relay J. The SCR is turned off, the coil of the relay J is not electrified, the normally open contact of the relay J is disconnected/kept disconnected, and the power supply 20 cannot reach the output OUT through the normally open contact disconnected by the relay J.
the base electrode of the second switch tube T2 is connected to the additional trigger power supply turn-off control signal output end of the monitoring controller 1 through a resistor R5, and the input end of the resistor R5 connected with the outside is the input control end for the power supply switch control module 10 to trigger turn-off.
The method for realizing the power saving and power supply of the man-machine combined monitoring device of the school bus and the on/off of the additionally arranged power switch control module 10 comprises the following steps:
the ignition switch detector 2 outputs a low level to an input control end which is connected with a power switch control module 10 and is triggered to be turned ON when detecting that an ignition key exits an ON gear, otherwise, outputs a high level to the input control end which is connected with the power switch control module 10 and is triggered to be turned ON;
Secondly, the vehicle door state detector 3 detects that the lower passenger door is in an open position, and outputs a low level to the input control end which is connected with the power switch control module 10 and triggers opening, otherwise, outputs a high level to the input control end which is connected with the power switch control module 10 and triggers opening;
Thirdly, when the power switch control module 10 receives that the ignition switch detector 2 and the vehicle door state detector 3 both output low levels, the SCR is triggered and kept on, the coil of the relay J is electrified, the normally open contact of the relay J is connected, and the power supply 20 reaches the output end through the normally open contact of the relay J;
After the patrol is finished or is stopped, the monitoring controller 1 outputs a high level to an input control end which is triggered to be closed by the power switch control module 10, the time delay is started when the monitoring controller 1 detects that the passenger door is not in an open position through the vehicle door state detector 3, and after the time delay is up, the monitoring controller 1 outputs a low level to the input control end which is triggered to be closed by the power switch control module 10 until the J coil of the relay is powered off;
and fifthly, the coil of the relay J is powered off, the normally open contact of the relay J is disconnected, and therefore the power output of the power switch control module 10 is cut off.
the above-mentioned delay time is set between 1 minute and 5 minutes.
the monitoring device is connected to a power-saving power supply state, and a monitoring program in the monitoring controller is set as follows: when the monitoring controller is powered on, the following defaults are performed: the ignition key exits from an ON gear and the door of the passenger car is located at an opening position, namely, the door of the passenger car is determined by default to be completely checked, a request output signal is sent to the human body detection system, a stop head (power head) of the safe door closing device is controlled to stretch out, namely, the monitoring controller controls the safe door closing device to be electrified and forbids the door to be closed, the monitoring controller controls the voice prompter to output a getting-off prompt tone with normal loudness, and patrol control is started to output response to the human body detection system and a patrol button.
As shown in fig. 5, the patrol implementing method in the power-saving power supply state of the monitoring device is as follows:
1) a timer for punishment is arranged in the monitoring controller;
