When event, if the reaction of driver slow half is clapped, tens meters of the distance then vehicle is possible to have moved ahead, thus will
Many security risks are resulted in, in addition at the greasy weather, due to unsighted, then this security risk odds will be at double
Increase；Therefore a kind of hidden danger simple with structure, easy to use, substantially reducing collision is developed, guarantees vehicle to a greater extent
The dead-man's device of safety guarantee in driving process has important application value.
Utility model content
The purpose of this utility model is to overcome existing drivers when driving vehicle when speed is too fast, prominent encountering
The reaction of hair-like condition and driver slow half is clapped, it will the problem of causing very big security risk, so that developing one kind has
Structure is simple, hidden danger easy to use, substantially reducing collision, guarantees the safety guarantee in vehicle travel process to a greater extent
Dead-man's device has important application value.
To achieve the above object, the technical solution of the utility model is: a kind of dead-man's device, including ranging sensing
Device, microprocessor, deceleration device, brake pedal are by vehicle interior power supply power supply, before the distance measuring sensor is located at vehicle body
End, to detect the real-time range of current vehicle front barrier, the microprocessor is located at interior of body, for receiving ranging
The signal of sensor transmission is simultaneously handled signal, is issued and is instructed to other components after the completion of processing, the ranging sensing
Device is electrically connected with microprocessor, and the deceleration device is located at interior of body and is electrically connected with microprocessor, and brake pedal is located at
It is electrically connected in driving and with microprocessor, the brake pedal and deceleration device are mechanically connected.
The distance measuring sensor uses LDM301 distance measuring sensor.
The microprocessor uses MAC7100 series microprocessor.
The beneficial effects of the utility model are:
By the way that distance measuring sensor is arranged in body structure, microprocessor and deceleration device are set in interior of body, ranging passes
To be electrically connected between sensor and microprocessor, it is electrically connected between microprocessor and deceleration device, deceleration device and brake pedal
Between for mechanical connection, to be electrically connected between brake pedal and microprocessor, vehicle in the process of moving works as distance measuring sensor
Sense front obstacle be less than safe distance when, microprocessor can be transmitted a signal to, handled by microprocessor and incite somebody to action
Instruction is sent to deceleration device, controls vehicle deceleration by deceleration device, when people have found in time and trample brake pedal, micro- place
Reason device can receive signal and be handled, and meeting microprocessor will be issued no longer to deceleration device and be instructed after the completion of processing, and vehicle subtracts
Speed is only slowed down with brake pedal and deceleration device；Generally: the utility model simple, user with structure
Just, the advantages of substantially reducing the hidden danger of collision, guaranteeing the safety guarantee in vehicle travel process to a greater extent.
Detailed description of the invention
Fig. 1 is the circuit theory control structure schematic diagram of the utility model；
Fig. 2 is per-vehicle equipment control principle structural schematic diagram in the utility model vehicle travel process.
In figure: 1, to the A vehicle 2 of right travel, distance measuring sensor 3, sensor emission light beam 4, sensor the reflected beams
5, to the distance of the B vehicle 6 of right travel, two vehicle of A, B.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Specific embodiment of the utility model, as shown in Figure 1, a kind of dead-man's device, including distance measuring sensor, Wei Chu
Device, deceleration device, brake pedal are managed by vehicle interior power supply power supply, the distance measuring sensor is located at body structure, with inspection
The real-time range of current vehicle front barrier is surveyed, the microprocessor is located at interior of body, for receiving distance measuring sensor
The signal of transmission is simultaneously handled signal, after the completion of processing to other components issue instruct, the distance measuring sensor with it is micro-
Processor electrical connection, the deceleration device are located at interior of body and are electrically connected with microprocessor, and brake pedal is located in driving
And be electrically connected with microprocessor, the brake pedal and deceleration device are mechanically connected, the distance which will measure
It is real-time transmitted to processor, if the processor detects that Ben Che is more and more closer at a distance from other objects in certain section of moment, is then
System will issue the signal of a deceleration, and automatic control motor slows down, and the size of deceleration and the size of distance are directly proportional, separately
Outside, during system automatic retarding, also can be stepped on brake by driver is influenced, if driver steps on rapidly brake,
Then the effect of system automatic retarding can gradually die down, it is ensured that vehicle is in the process of moving due to too fast, the vehicle stall that slows down
The occurrence of.
The distance measuring sensor uses LDM301 distance measuring sensor, and measuring principle is using the laser pulse flight time
Mensuration, the sensor can measure fixed or moving object distance and speed, and time of measuring is very short, and measurement range is
0.5-300m, the reachable ± 20mm of precision, operating temperature are -40 DEG C -70 DEG C.
The microprocessor uses MAC7100 series microprocessor.
Specific embodiment: if 1, the A vehicle 1 as shown in Figure 2 when to right travel is with the B vehicle 5 to right travel in same lane
In the same direction in traveling, the distance that LDM301 distance measuring sensor 2 will test sends microprocessor to, when 1 speed of A vehicle to right travel
Degree be greater than to right travel B vehicle 5 when, two vehicles apart from it is smaller and smaller when, system can automatically control the A of deceleration device opposite direction right travel
Vehicle 1 is slowed down accordingly；
If the distance that LDM301 distance measuring sensor 2 will test sends microprocessor in 2, being travelled in opposite directions when two vehicles
, when two vehicles apart from it is smaller and smaller when, system can automatically control deceleration device and be slowed down accordingly to two vehicles；Generally, originally
Utility model simple, hidden danger easy to use, substantially reducing collision with structure, guarantees in vehicle travel process to a greater extent
Safety guarantee the advantages of.
