The vehicle-mounted security-monitoring equipment provided by taking physical circuit shown in Fig. 4 as an example the utility model embodiment below is opened
The operation principle on electromechanical road 100 elaborates：
Specifically, when electronic lock status information H-KEY is low level, second switch element Q2 conductings, and according to input
Voltage PWR2 powers to reset chip U1, and input voltage PWR2 is by first resistor R1, second resistance R2, the first capacitance C1, the
The power-switching circuit of two capacitance C2, the first diode D1 and first switching element Q1 compositions turns vehicle power supply PWR1
Change gained；Reset chip U1 is charged after the power is turned on by the 8th resistance R8 to charging capacitor C4, since charging capacitor C4 is smaller, generally
For microfarad range, then the charging voltage of charging capacitor C4 rises to the threshold voltage of 0.7V quickly, at this point, reset chip U1 continue to
Charging capacitor C4 charges.
After the voltage of charging capacitor C4 is more than the threshold voltage of 0.7V, the 6th switch element Q6 conductings, the 6th switch member
The control terminal voltage PWR1 of the 7th switch element Q7 will be dragged down after part Q6 conductings, so that seven switch element Q7 end, and then is made
It obtains vehicle power supply PWR1 and power circuit 200 is opened by the 19th resistance R19, so that power circuit 200 is according to the vehicle power supply
PWR1 works, and device 300 provides operating voltage V-MCU in order to control.
After the voltage of charging capacitor C4 is more than the threshold voltage of 0.7V, the 4th switch element Q4 conductings, and then pass through the
13 resistance R13 drag down its input terminal voltage, and export trigger notice signal to controller 300；Controller 300 is according to work electricity
Pressure V-MCU is detected trigger notice signal after starting, i.e., controller 300 detects the level height at its own trigger notice end
It is low；When the level for detecting itself trigger notice end is low level, controller 300 confirms that trigger notice signal is touched for electronic lock
It signals, i.e., vehicle-mounted security-monitoring equipment is electronic lock triggering booting, its own power supply control end is set to high level by controller 300,
So that the 5th switch element Q5 is connected, so that the 5th switch element Q5 draws the control terminal voltage of the 7th switch element Q7
It is low, the 7th switch element Q7 is caused to end, so that power circuit 200 continues to vehicle power supply PWR1 and supplied to controller 300
Electricity；Meanwhile the output control signal control third switch element Q3 conductings of controller 300, so that charging capacitor C4 passes through the 9th electricity
Resistance R9, third switch element Q3 discharge, to realize that state is reset.
In addition, controller 300 is detected electronic lock status information H-KEY, when electronic lock status information H-KEY becomes
High level state, that is, when meeting electronic lock compressor start up condition, controller 300 opens vehicle-mounted security-monitoring equipment；When electronic lock status information
H-KEY also keeps low level state, that is, when being unsatisfactory for electronic lock compressor start up condition, controller 300 is by the power supply control end of its own
Low level state is converted to from high level state, the 5th switch element Q5 cut-offs, the 7th switch element Q7 is according to input voltage
PWR2 is connected, and then drags down the vehicle power supply PWR1 for being input to power circuit 200, so that power circuit 200 stops to control
Device 300 processed is powered, and to cut off power itself, maintains the zero-power state of system；It should be noted that in the present embodiment, control
Device 300 processed can be by chip microcontroller.
Further, if do not need to electronic lock booting, the boot-strap circuit of the vehicle-mounted security-monitoring equipment shown in the utility model
100 can also pass through car key igniting booting and timing start-up.
Specifically, when clock timing chip meets the time of setting, the clock timing signal of clock positioning chip output
RTC becomes low level from high level, and the starting-up signal ACC that strikes sparks at this time is low level, and due to the resistance of the 20th resistance R20
It is worth very little, therefore, the 7th switch element Q7 ends according to the low level clock timing signal RTC, so that vehicle power supply
PWR1 opens power circuit 200 by the 19th resistance R19, so that power circuit 200 provides operating voltage V- to controller
MCU so that controller 30 works to detect timing start-up signal, and starts when timing start-up signal meets compressor start up condition
Vehicle-mounted security-monitoring equipment.
After driver is struck sparks using car key, it will export the sparking starting-up signal ACC of high level to the 21st resistance
R21, the 22nd resistance R22 and the 8th switch element R8, since clock timing signal RTC is high level at this time, and the 8th
Switch element R8 is connected according to the sparking starting-up signal ACC of the high level, and therefore, the 8th switch element Q8 of conducting is opened the 7th
The high level for closing element Q7 control terminals drags down, so that the 7th switch element Q7 ends, passes through from vehicle power supply PWR1 is caused
19th resistance R19 opens power circuit 200, so that power circuit 200 provides operating voltage V-MCU to controller, from
And controller 300 is worked to detect car key sparking starting-up signal, and when car key sparking starting-up signal meets booting item
Start vehicle-mounted security-monitoring equipment during part.
Further, the utility model embodiment also provides a kind of vehicle-mounted security-monitoring equipment, which includes electricity
Source circuit 200, controller 300 and above-mentioned boot-strap circuit 100.
Further, the utility model embodiment also provides a kind of motor vehicles, which includes above-mentioned vehicle-mounted
The boot-strap circuit 100 of security device.
In the embodiment of the utility model, touched by using including power control module 10, charging module 20, electronic lock
The boot-strap circuit 100 of 40 vehicle-mounted security-monitoring equipment of module of sending out public notice 30 and dump block so that when electronic lock status information is the
During one state, charging module 20 charges and exports charging voltage, and power control module 10 is according to charging voltage controlling power circuit
200 provide operating voltage to controller 300；Electronic lock trigger notice module 30 exports trigger notice signal extremely according to charging voltage
Controller 300；Controller 300 starts according to operating voltage, and trigger notice signal is detected；When trigger notice signal is
During electronic lock trigger signal, controller 300 drives 10 controlling power circuit 200 of power control module to power to controller 300, together
When controller 300 control dump block 40 discharge charging module 20；And controller 300 to electronic lock status information into
Row detection, when electronic lock status information is the second state, controller 300 opens vehicle-mounted security-monitoring equipment；When electronics lock status is believed
When breath keeps first state, controller 300 stops driving 10 controlling power circuit 200 of power control module and is supplied to controller 300
Electricity, and then realize that using the characteristic of electronic lock be start-up mode of the vehicle-mounted security-monitoring equipment increase without car key, vehicle can be realized at any time
The booting of security device is carried, in order to which operating personnel safeguard equipment；And in the situation for meeting electronic lock compressor start up condition
Lower opening vehicle-mounted security-monitoring equipment, and power itself is disconnected in the case where being unsatisfactory for electronic lock compressor start up condition, it thereby reduces out
Machine power consumption sets so as to solve the Starting mode of existing vehicle-mounted security-monitoring equipment in the presence of cannot meet user and carry out vehicle-mounted security-monitoring at any time
It is standby to safeguard, and if the problem of carrying out there is also high energy consumption during plant maintenance.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
