Abstract
The invention can be given the clear and definite speed(-)limit sign value of driver in the speed limit highway section of automobile regulation; When automobile travels above qualification speed, send audible and visual alarm to the driver, and the overspeed condition stored record can be got off, meanwhile, automatically control throttle and force vehicle deceleration; The dynamic process of energy recording storage accident carries out the traffic safety supervision to automobile when automobile urgent brake, control and management.
Description
The invention belongs to the automatic monitoring control equipment of overspeed of vehicle and emergency circumstance operation inertia, and it relates to the transmission received code of radio signal, the automatic control of vehicle power transmission, the fields such as monitoring management of traffic safety.
At present, the monitoring and control equipment that automobile travels in the speed limit highway section, main instantaneous the testing the speed of radar of adopting the disengaging car body.Control survey is subjected to the restriction of conditions such as weather, physical features and manpower, the error mistakes and omissions often occur.Disclosed Chinese patent CN86105883 " monitor for overspeed driving car " is the variable light source by remote signal control car body, the hypervelocity automobile is sent functional obstacles such as sound equipment, light, the car speed of will driving over the speed limit artificially after the driver is disturbed descends, CN86204251 disclosed " hypervelocity monitoring, alarming registering instrument ", then be to specify maximum speed limit by magnetic control, detect switch activated alarm logging device during hypervelocity, passive type ground carries out monitoring record to the hypervelocity automobile.
Purpose of the present invention is to give the automobilist speed(-)limit sign accurately in the speed limit highway section of regulation; When automobile travels above qualification speed, by testing the speed and the sampling comparison process of microsystem of speed pickup, send sound, the light alarm of hypervelocity to the automobilist, simultaneously, data storage is noted overspeed condition, speed limit topworks also controls throttle by stepper motor, initiatively car speed is eased down to the setting of restriction; When automobile during at emergency circumstance brake steering dish, by the inertia sensor, microsystem, data storage are noted all processes of emergency brake, as the foundation of analysis and judgement accident.
The system of the invention constitutes as shown in Figure 1.
Transmitter (1) is installed in the place, gateway that needs automobile is carried out the speed limit running section, also can be installed in the center in speed limit highway section, perhaps on the point duty car of Liu Donging.Transmitter (1) adopts 220 volts of Alternating Current Power Supply continuous workings around the clock, when not having AC power, then adopts the power supply of solar photocell and battery pack.Transmitter (1) can send the signal of a plurality of different coding instructions as required, represents various different speed limits or other instructions.
Receiver (2), speed pickup (3), inertia sensor (4) microsystem (5), speed(-)limit sign (6), overspeed alarming (7), data storage (8), hypervelocity incident monitoring (9), speed limit topworks (11), Throttle Opening Control (12), dredge radio station (14), be installed on the automobile in the same housing.
Machine for receiving and emitting message is operated in the very mixed and disorderly interference environment of radiowave, in order to improve the antijamming capability of receiver (2), prevents to fail to report or make a false report, and the speed(-)limit sign signal encoding of machine for receiving and emitting message adopts:
1, five get two combinational code mode: promptly in five useful coded signals, only get the wherein grouped location of crucial two sign indicating numbers in five sign indicating numbers, forms 10 various combination signals, need only the signal code difference, receiver will not receive;
2, integration accumulation mode: promptly identical the but pulse width of signal code not simultaneously, receiver also will not receive;
3, repeat judgment mode: promptly under the situation that above-mentioned two conditions all satisfy, receiver is only received that twice identical signal just gives and is admitted.
When receiver (2) is received the restricting signal of regulation, then start microsystem (5) work, the speed limit that impels speed(-)limit sign (6) display automobile to travel in this highway section clearly limits the speed of driver driving.
The record automobile driving speed is undertaken by speed pickup (3).Speed pickup (3) adopts threeway to connect form by a flexible axle, is attempted by on the automobile hind axle case with autometasomatism.This root flexible axle drives a transparent plate and rotates, and produces the pulse that is directly proportional with speed by the photoelectricity coupled system, and input microsystem (5) is measured its speed of a motor vehicle.
Microsystem (5) adopts single-chip microcomputer.The sampled data of automobile driving speed compares and calculates with the regulation restricting signal.When automobile speed surpasses limit value, microsystem (5) can log-on data be stored (8), automatically hypervelocity is worth the stepping cumulative record, deposits database in, and can monitor and observe total degree and total kilometer of its hypervelocity at any time by hypervelocity incident monitoring (9).Because adopt standby power supply in the microcomputer, under the situation of automobile power-down, data-base content can not lost yet.
When microsystem (5) was differentiated overspeed driving car and is recorded in database, overspeed alarming (7) sent the alarm signal of light harmony, also starts speed limit topworks (11) on the other hand.Speed limit topworks is serially connected on the throttle control line by driving device for step-by-step, and it is rotated to an angle according to the pulse signal of hypervelocity, by gear train, the hypervelocity gas is reduced gradually, causes the speed of a motor vehicle to slow down automatically.After automobile sailed out of the speed limit highway section, stepper motor was auto-reverse, got back to initial position, and automobile recovers normal speed and travels.Automobile is in the whole driving process in speed limit highway section, and the driver still can handle the control throttle on demand flexibly and overtake other vehicles and travel, do not influence automobile overtake other vehicles, climb, required power system work when starting, to prevent various fortuitous events.At this moment, under situation about not exceeding the speed limit, data-storage system can not carry out record.
In order to write down the process of automobile driver control bearing circle or when having an accident in emergency circumstance brake, the reason that the analysis and distinguishing accident takes place, the present invention adopts the inertia sensor (4) of top sieve principle, dynamo-electric combination.At automobile accident or when running into emergency brake, the driver is steering wheel rotation inevitably, when vehicle body produces certain vertical or horizontal inertia, the situation of rocking by top sieve, start microsystem work, Automobile Dynamic inertia accurate recording is got off, as the foundation of traffic superintendance analysis and judgement accident.Automobile Dynamic inertia can be preserved 30 days, and the record that surpasses 30 days is removed every day automatically.
Print system (10) is made portable type, uses for vehicle supervision department, can check the travel situations of each automobile at any time, print date, hypervelocity number of times and summation that this car is driven over the speed limit, hypervelocity kilometer and summation are for vehicle supervision department provides accurate data, as rewards and punishments driver's foundation.
Dredge radio station (13) (14) and adopt the HFBC high frequency broadcasting frequency range, in 88-108MHZ, select a specific frequency for use.The radio station can be arranged on automobile, point duty car or the fixed position, with timely processing traffic hazard.
