Description
Technical field
The invention belongs to traffic safety facilities technical fields, and in particular to a kind of anti-early warning dress that knocks into the back of sweeper night
It sets.
Background technique
Since vehicle flowrate is more on road in the daytime, travel speed is slower when the sweeper work of road administration, is also easy to produce traffic and gathers around
It is stifled, and night since traffic volume of highway is smaller, so the sweeper of road administration is mainly being worked at night.But night is strong due to illumination
Degree is insufficient, and object visibility and identification are lower, and the difficulty of driver's perception information is larger, and obtaining relevant information can be insufficient, adds
Travel speed is slower when the sweeper that upper driver is easy to produce fatigue and road administration works, and is easy that driver is allowed to generate relative distance
Erroneous judgement.The sweeper of road administration is often easy to be knocked into the back by driver when working at night.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of sweeper night rear-end collision prevention early warning systems.
Technical scheme is as follows:
A kind of sweeper night anti-knock into the back prior-warning device, including machine box, power supply, single-chip microcontroller central processing unit, light sensor
Device, millimetre-wave radar, Hall sensor, angular-rate sensor, led direction board and directional loudspeaker.
The inner surface of the machine box is equipped with fixed connection device, for connecting with sweeper aftercarriage；Appearance on the other side
Led direction board, directional loudspeaker and millimetre-wave radar are fixed in face, and directional loudspeaker and millimetre-wave radar hang down with outer surface respectively
Directly, millimetre-wave radar obtains the motion information of rear area target vehicle, including vehicle headway, relative velocity.Machine box upper surface is fixed
Photosensitive sensor；Photosensitive sensor obtains external light intensity information；Hall sensor and angular-rate sensor are fixed on machine box
Side, angular-rate sensor act on angle measurement when bend, and Hall sensor is then used to measure the traveling speed of automobile itself
Degree.Fixed single-chip microcontroller central processing unit and power supply inside machine box.
The single-chip microcontroller central processing unit respectively with power supply, photosensitive sensor, millimetre-wave radar, Hall sensor and angle
Velocity sensor is connected；Single-chip microcontroller central processing unit output interface passes through relay template respectively and raises with led direction board and orientation
Sound device is connected.
Further, photosensitive sensor, millimetre-wave radar, Hall sensor and angular-rate sensor and single-chip microcontroller centre
Device is managed to connect by 485 interfaces.
When external light intensity lower than setting threshold values when, photosensitive sensor issue signal by single-chip microcontroller central processing unit to
Machine state switchs to working condition, and single-chip microcontroller central processing unit output signal control led direction board is bright, reminds rear vehicle evacuation.When
In when accelerating proximity state, and being less than apart from threshold values, single-chip microcontroller central processing unit exports the sweeper of front vehicle and road administration
Signal controls directional loudspeaker and carries out voice reminder to front vehicle, and directional loudspeaker can avoid noise at night and disturb residents.
Beneficial effects of the present invention:
The present invention can effectively monitor front vehicle and vehicle range information at night, determine that front vehicle knocks into the back generally
Rate is actively reminded.
