Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
Embodiment
As shown in Figure 1, mountain area bend overspeed of vehicle warning device mainly comprises first coil 1, second coil 2, tertiary coil 3, the 4th coil 4, signal processing apparatus 5, first display screen 6 and second display screen 7; Wherein, first coil 1, second coil 2, tertiary coil 3 and the output terminal of the 4th coil 4 are connected the input end of signal processing apparatus 5 respectively, and the output terminal of signal processing apparatus 5 connects first display screen 6 and second display screen, 7 input ends respectively; The signal of first coil 1 and second coil 2 sends to first display screen 6 and shows after signal processing apparatus 5 is handled; The signal of tertiary coil 3 and the 4th coil 4 sends to second display screen 7 and shows after signal processing apparatus 5 is handled;
First coil 1 and second coil 2 are embedded in the craspedodrome highway section (two coil-spans from be 4 meters) of hairpin curve one side successively, in the roadside in the straight shape of this side highway section first display screen 6 are installed; Tertiary coil 3 and the 4th coil 4 are embedded in the craspedodrome highway section of hairpin curve opposite side successively, and in the roadside in this side craspedodrome highway section second display screen 7 are installed; The signalization treating apparatus 5 at the turning.
Coil is used for whether judging the information of sending a car through the variation of self-inductance; First coil 1, second coil 2, tertiary coil 3 and the 4th coil 4 all adopt the toroid winding vehicle detection apparatus; The toroid winding vehicle detection apparatus is made up of power supply, coil, voltage-controlled LC oscillatory circuit and detection module; Wherein, Power supply is the power supply of toroid winding vehicle detection apparatus, and coil links to each other with the signal input part of voltage-controlled LC oscillatory circuit, the output terminal connection detection module of voltage-controlled LC oscillatory circuit.Power supply is selected if0505s-1w type microcontroller power supply module for use; Coil is selected the LGX coil for use, and voltage-controlled LC oscillatory circuit is used for the induced signal of receiving coil, and the frequency signal that will respond to quantitative changeization sends to detection module; Detection module adopts the STC89C51 single-chip microcomputer.
Signal processing apparatus 5 is used for judging according to received signal whether vehicular traffic exceeds the speed limit and triggers corresponding program simultaneously, lets display screen carry out command adapted thereto; Signal processing apparatus 5 is selected the STC89C51 single-chip microcomputer for use.
First display screen 6 and second display screen 7 are used for display reminding information, and alerting drivers takes in a reef, and deceleration is gone slowly.The displaying contents of display screen is divided into two parts: the first half shows that " send a car in the opposite! Vehicle speed value: (like 70km/h) ", the latter half shows " this car vehicle speed value: (like 50km/h) " or " this car hypervelocity! Vehicle speed value: (like 70km/h) ".First display screen 6 and second display screen 7 all adopt the full-color low pressure of internal control (P16) type LED electronic display.
The principle of work of the utility model is following:
As vehicle during successively through first coil 1 on the mountain area bend one side line road and second coil 2; The inductance value that causes first coil 1 and second coil, 2 coils respectively changes; And then trigger pip treating apparatus 5; When signal processing apparatus 5 processing signals, be meant time T value and the setting value T0 of comparison vehicle through two coils; If if T T0, then signal processing apparatus 5 triggers the instruction that first display screen 6 shows information warnings, make display screen 6 the latter halfs of winning send the caution literal " this car hypervelocity! Vehicle speed value (like 70km/h) ", second display screen, 7 the first half show simultaneously: " send a car in the opposite! Vehicle speed value (like 70km/h) "; If T >=T0, then the information warning instruction does not respond, first display screen, 6 the latter half display texts " this car vehicle speed value (like 50km/h) ", second display screen, 7 the first half show simultaneously: " send a car in the opposite! Vehicle speed value (like 50km/h) ".In like manner, when mountain area bend road opposite side was sent a car, the demonstration situation was opposite.
The process that shows toy vehicle velocity value is the computation processes of 5 pairs of vehicles of signal processing apparatus through two coil times: signal processing apparatus 5 picked up counting when for example vehicle sailed first coil 1 into; Signal processing apparatus 5 stopped timing when vehicle sailed second coil 2 into; Like this, vehicle is known through the actual travel time T of two coils.Owing to the distance between two coils is known (S=4m), so the vehicle ' speed V can be calculated through V=S/T.The shortest running time T0 that stores in advance in the single-chip microcomputer is example through calculating with maximum speed limit V0=60km/h, and the shortest running time T0 computing formula is: T0=S/V0=4/60000=0.24s.
Referring to Fig. 2, the workflow of the utility model is following:
Step 1: initialize routine;
Step 2: signal processing apparatus 5 has detected car to be passed through first coil 1 (or tertiary coil 3) time and picks up counting;
Step 3: signal processing apparatus 5 has detected and has stopped timing when car passes through second coil 2 (or the 4th coil 4);
Step 4: signal processing apparatus 5 calculates actual travel time T and relatively actual travel time T and the shortest running time T0, when T during T0, execution in step 5; As T >=during T0, execution in step 6;
Step 5: first display screen 6 (or second display screen 7) the latter half shows " hypervelocity! Vehicle speed value ",
Display screen 7 (or first display screen 6) the first half shows that " send a car in the opposite simultaneously! Vehicle speed value ";
Step 6: first display screen 6 (or second display screen 7) the latter half shows " vehicle speed value ", second display screen 7 (or first display screen 6) the first half shows that " send a car in the opposite simultaneously! Vehicle speed value ";
Step 7: when passing through signal as if no vehicle, execution in step 1.
