Abstract

The utility model provides a traffic accident signaling system, comprising a trigger circuit, a radio transmitter circuit, a radio receiver circuit and an output indicating circuit, wherein the trigger circuit is connected with the radio transmitter circuit; the radio receiver circuit is connected with the output indicating circuit; and when the trigger circuit is triggered, a radio transmitter transmits trigger signals, the radio receiver circuit receives the trigger signals and transmits the trigger signals to the output indicating circuit, and the output indicating circuit emits the indicating signals. The utility model can be made into a warning box to be installed on an automobile and be triggered by a card with a magnetic sheet. The utility model is particularly suitable for express ways, if a false alarm is generated during the traveling, the card can be inserted again to solve the problem. When a vehicle collides or rolls over, the trigger circuit is triggered, warning signals are emitted to the vehicles within the peripheral range of 1 kilometre or a plurality of kilometers by the radio transmitter to notify the approaching vehicles to avoid, and thereby the utility model can effectively avoid the happening of chain rear-end collision accidents.

Description

The traffic hazard warning system

Technical field

The utility model relates to a kind of warning system, relates in particular to a kind of warning system of traffic hazard.

Background technology

Along with the fast development of road traffic and auto industry, the automobile on highway of travelling is more and more, speed is also more and more faster, and the traffic hazard of Yin Faing also is being on the increase thus, and the automobile chain of rings incidence that bumps against serious accident that knocks into the back remains high especially; Especially descend at inclement weather such as rain, snow, mist or the bad situation of sight line, major traffic accidents take place especially easily, have caused irremediable heavy losses for people's lives and properties.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of active prompting and prevents the traffic hazard warning system that automobile shunts into one another.

For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of traffic hazard warning system, comprise trigger circuit, wireless transmitter circuit, wireless receiving machine circuit, output indicating circuit, trigger circuit link to each other with wireless transmitter circuit, the wireless receiving machine circuit links to each other with the output indicating circuit, trigger circuit send trigger pip once triggering by transmitting set, the wireless receiving machine circuit receives trigger pip, and, send indicator signal by the output indicating circuit with trigger pip transmission and output indicating circuit.

The utility model can be made the warning box and be installed on the automobile, is triggered by the card that has magnetic sheet.Be particularly useful on the highway, and middle if any false alarm, can pass through again plug-in card and get final product.

The utility model adopts above-mentioned design, when collision happens or rollover, trigger circuit triggers, 1 kilometer or the vehicle of number in the kilometer range send early warning signal towards periphery by transmitting set, announcement just note dodging at the vehicle of approaching, thereby can avoid the generation of rear-end collision accident effectively.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Fig. 1 is the circuit block diagram of the utility model traffic hazard warning system.

Fig. 2 is the electrical schematic diagram of trigger circuit and a kind of embodiment of wireless transmitter circuit among Fig. 1.

Fig. 3 is the electrical schematic diagram of a kind of embodiment of wireless receiving machine circuit among Fig. 1.

Embodiment

As shown in Figure 1, the utility model traffic hazard warning system comprises trigger circuit I, wireless transmitter circuit IV, wireless receiver circuit I I, output indicating circuit III, trigger circuit I links to each other with wireless transmitter circuit IV, wireless receiver circuit I I links to each other with output indicating circuit III, trigger circuit I sends trigger pip once triggering by wireless transmitter circuit IV, wireless receiver circuit I I receives trigger pip, and with trigger pip transmission and output indicating circuit III, III sends indicator signal by the output indicating circuit.

As shown in Figure 2, trigger circuit I comprises relay J, controllable silicon SCR, the first tongue tube H ₁, on-off circuit I ₁With power supply V ₁, switching branches I ₁Trigger switch by 3 parallel connections is formed, several trigger switches also can be set certainly more, the first trigger switch K1 device is in the headstock or the parking stall of car, the 3rd trigger switch K3 device is at Vehicular side body, the first trigger switch K1 and the 3rd trigger switch K3 are mercury cut-off, the second trigger switch K2 is a danger button, by manually manual triggering under emergency.Power supply V ₁With the first tongue tube H ₁The series arm of forming is in parallel with the series arm that relay and controllable silicon SCR are formed, switch I ₁Two ends be connected the motion end K of relay J with the trigger electrode of positive source and controllable silicon SCR respectively _JT links to each other with transmitting set.The first tongue tube H ₁Folding control by magnetic sheet, magnetic sheet is installed on the magnetic card.As long as magnetic card is near the first tongue tube H ₁, the first tongue tube H ₁Trigger, trigger circuit are in running order, in case on-off circuit I ₁Trigger, then the motion end K of relay _JClosure, transmitting set T launches alerting signal.
