Towel, laptop, USB connecting lines.
After system docking, specific demarcating steps are：1) after completing equipment connection, there is blue indicator light bright on the inside of host
2) APN setting (using SIM card be flow card when need to be arranged), SIM card is inserted into machine by the first step, connection equipment with electricity
Brain powers on and interface is waited for jump out；Second step, into main interface after click " setting "；Interface is being arranged in third step, clicks software
It is drawn downwards on the upside of interface, status bar is skidded off；4th step after clicking mobile data icon, is clicked " more settings "；5th step,
Into after more settings, the icon of three dots in the upper right corner, reselection mobile network are clicked；6th step, into mobile network circle
Behind face, select " access point name (APN) "；7th step after interface is arranged into APN, is clicked the upper right corner "+" icon, is increased newly
APN；8th step is filled corresponding A PN information and is preserved, return to upper level catalogue, select the APN, and restart in newly-increased interface
Machine；3) activation equipment first uses usb connecting lines if when using normal SIM card, after completing equipment wiring, not power on first
Device Host and laptop are connected, the vysor softwares in computer are opened, after the power is turned on, system will start, and start needs for the first time
Offer half point clock time, activation interface can be popped up for the first time by starting, and needed correctly to fill in relevant information, be paid attention to：One is often demarcated
Che Hou needs the IMEI number (being posted on rear side of yaw host) for recording current device and the license plate number of vehicle, vehicle interior to compile
Number, the information such as the affiliated company of vehicle, and report to back-stage management person's information, otherwise equipment can only single-unit operation, after having filled in information,
Under conditions of ensureing equipment networking, activation is clicked, if having inserted sim cards, the image upper right corner should show 4G
Signal；4) equipment calibration, the first step, parameter are filled in, and are selected " setting "->" calibration setting ", with tape measure several ginsengs as follows
Number, and fill in, bumper distance is distance of the host camera to headstock front end.When measuring overall height and scaling board height, need
Pay attention to ensureing tape measure perpendicular to ground.Scaling board height refers to vertical range of the scaling board center line away from ground, needs to ensure to mark
Fixed board center line should be equal to right wheel distance apart from about 1.25 meters of ground, left wheel distance, be spacing on the outside of left and right wheels
Half, (if host fails to be mounted on windshield horizontal centre, left wheel distance is not equal to right wheel distance, needs at this time
Measure respectively) click the storable numerical value for filling in completion after preservation；Finally, by scaling board be placed in immediately ahead of host 4 to 5 meters it
Between, and keep scaling board with headstock in same parallel surface, under the premise of completing scaling board placement, selection " setting "->" calibration
Setting "->" picture setting " adjusts camera angle by screwdriver, the green horizontal line in picture is made to be aligned in scaling board
Heart line (allows minor deviations), and then point determines, completes calibration.
Step S102, monitors whether first running data triggers default braking condition；
The set of circumstances that default braking condition is formulated for each corresponding first running data；Default braking condition includes
But it is not limited to distance braking condition, spacing braking condition, track braking condition and driver status braking condition；Specifically, position
Vehicle position information is uploaded in background server by the monitoring needs station acquisition device for setting braking condition, in background server
In the location information is monitored, local prison is carried out in the control system that other braking conditions can be on being set to vehicle
It surveys.
Step S103, if monitor it is described first traveling data-triggered preset braking condition, the control device to
The motor vehicle braking system sends the first brake control signal and executes default braking to the vehicle by motor vehicle braking system
Operation.
Control device and the vehicle braking system of itself are connect by wired or wireless way；When monitoring the first traveling number
After meeting default braking condition, control device sends the first brake control signal to the braking system of vehicle itself and passes through vehicle
Braking system executes vehicle and presets brake operating.
As shown in Fig. 2, according to other embodiments of the invention,
It monitors first running data and whether triggers default braking condition and include：
Step 201, the first position information that the harvester collects is uploaded to the background server, and with

Step 502, monitor whether first driver status meets default dangerous driving state；
Default dangerous driving state include but not limited to close one's eyes, yawn, posture is abnormal, makes a phone call, smoke etc., and harm are pacified
The behavior driven entirely.
If monitoring the first traveling data-triggered presets braking condition, control device executes braking to the vehicle
Operation includes：
Step 503, if monitoring first driver status meets default dangerous driving state, vehicle execution is controlled
Brake operating.
When the control system being set on vehicle judges that driver is currently at default dangerous driving state, pass through control
Device intervenes vehicle itself braking system, and executes brake operating to the vehicle.
In some embodiments, by driver's expression, posture, action etc. be foundation, quickly, in real time, effectively examine
Survey fatigue driving state, and send out acousto-optic pre-warning signal to driver, when closing one's eyes occurs in driver, yawns, posture extremely, beat
Phone, smoking etc. are unfavorable for issuing warning signal to driver when the behavior attentively driven.
It can be seen from the above description that the present invention realizes following technique effect：
In the embodiment of the present application, using the side for the running data being provided in harvester collection vehicle driving process
Formula has reached and has been sent to motor vehicle braking system by control device by monitoring whether running data triggers default braking condition
