Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-Figure 2, a kind of wireless speed of a motor vehicle display annunciator, comprise sender unit, signal receiving device and read out instrument, described sender unit comprises electronic tachometer 1, speed of a motor vehicle extraction assembly and Bluetooth transmission module 3, described signal receiving device comprises power supply 8, Bluetooth receptions module 4, memory module 9, display module 7 and micro controller system 12, described read out instrument comprises the first read-out 5, second display screen 6 and camera assembly, described electronic tachometer 1 and speed of a motor vehicle extraction assembly are all connected with Bluetooth receptions module 4 wireless signal by Bluetooth transmission module 3, described Bluetooth receptions module 4, memory module 9, display module 7 is all connected with power supply 8 by micro controller system 12, described first read-out 5, second display screen 6 and camera assembly are all connected with power supply 8 by display module 7, described camera assembly is also electrically connected with memory module 9.
Particularly, described speed of a motor vehicle extraction assembly comprises ELM327 Auto analyzer 2, and described ELM327 Auto analyzer 2 gathers automobile speed data by OBD2 interface.
Particularly, described camera assembly comprises camera 11 and is arranged on the LED row 10 of camera about 11 both sides.
Particularly, described first read-out 5 and second display screen 6 are color LED screen, and described first read-out 5 and second display screen 6 are equipped with Warning light 13.
Particularly, described first read-out 5 is electrically connected with electronic tachometer 1 by micro controller system 12, and described second display screen 6 is electrically connected with speed of a motor vehicle extraction assembly by micro controller system 12.
This annunciator gathers the speed of front vehicles by electronic tachometer 1, the moving velocity of vehicle is gathered by ELM327 Auto analyzer 2, again two vehicle speed signal are passed to micro controller system 12 by Bluetooth transmission module 3 and Bluetooth receptions module 4, data are sent to display module 7 by micro controller system 12, and display module 7 controls the first read-out 5 again and the speed of a motor vehicle numerical value of correspondence shows by second display screen 6 respectively; Signal receiving device and read out instrument are all arranged on the tailstock, be convenient to front vehicle observe, and the traveling that camera 11 is mainly used for gathering front vehicle is recorded a video, video recording is stored into memory module 9, transferring data after occurring to facilitate accident, LED arranges 10 can play booster action at night.
When self car is in docked state, then the speed of a motor vehicle is 0, second display screen 6 then can show and " stop! ! ! " printed words, and the first read-out 5 is in off position does not namely show state.
When self car is in motoring condition, then the first read-out 5 is used for showing the vehicle speed data of front nearest vehicle, the vehicle speed data of self car of second display screen 6 display; When the speed of a motor vehicle of front car is at 50KM/H-100KM/H, the speed of a motor vehicle numerical value on the first read-out 5 is blinking yellow illumination state, and now, the Warning light 13 on the first read-out 5 is OFF state; When the speed of a motor vehicle of front car is lower than 50KM/H, the speed of a motor vehicle numerical value of the first read-out 5 takes on a red color quick flashing state, the blink states and the Warning light 13 now on the first read-out 5 takes on a red color.When self speed of a motor vehicle is at 50KM/H-100KM/H, the speed of a motor vehicle numerical value on second display screen 6 is blinking yellow illumination state, and now, the Warning light 13 on second display screen 6 is OFF state; When self speed of a motor vehicle is lower than 50KM/H, the speed of a motor vehicle numerical value of second display screen 6 takes on a red color quick flashing state, the blink states and the Warning light 13 now on second display screen 6 takes on a red color.
In fact, the screen size of the first read-out 5 is less than the size of second display screen 6, because in whole annunciator, core shows mainly second display screen 6, and such size is designed with and is beneficial to front vehicle more clearly ground identifying information.
In fact, the detection range of electronic tachometer 1 is 250 meters, namely electronic tachometer 1 effectively can detect the vehicle in the distance range of 250 meters, dead ahead, when not having vehicle to travel within the scope of this, then not displaying contents on the first read-out 5, the content of two read-out displays can be reduced like this, prevent the chaufeur of front vehicle because the content of two display screen displays is too much and dazzled.
This logic is arranged can not only play warning function by the speed of a motor vehicle of self to vehicle below effectively, when rear car is unsighted, the running state of front truck can also be shown, to the reaction time that rear car is enough, more ensure that the safety of high speed traveling.
The invention has the beneficial effects as follows, the speed of a motor vehicle that this is wireless display annunciator can show in real time to the front speed of a motor vehicle and self speed of a motor vehicle, adopt Bluetooth wireless transmission to rear read-out, can play warning function effectively to front vehicle, this structure design also can reduce the setting of winding displacement, installs more convenient, on a display screen camera assembly is installed, Real-time Collection can also being realized to front vehicle motoring condition, there is higher practicality, also popularizing than being easier to.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine its technical scope according to right.
