Abstract

The invention relates to traffic safety, in particular to a safety system provided for unattended railway and highway crossings. The invention solves the technical problems of the safety of vehicles and pedestrians at the railway and highway crossings. The safety system is characterized by comprising LED (Light-Emitting Diode) display screens (2), traffic lights (3) and alarm buzzers (5) vertically arranged by the road at both sides of the railway, guardrail tracks, guardrails (7) and guardrail controllers (6) arranged at both sides of the railway and vibration sensors (4), singlechips (8) and power supplies (1) arranged on the tracks of the left sides and the right sides of the crossings. When a train is about to arrive the railway and highway crossings, the vibration sensors detect vibration signals and transmit the vibration signals to the singlechips, the singlechips control the LED display screens and the traffic lights and the alarm buzzers to give alarms, and the guardrails close the crossings; after the train passes, the singlechips control the LED display screens, the traffic lights and the alarm buzzers to stop giving the alarms, and the guardrails return to the original positions, and thereby, the safety of the vehicles and the pedestrians is ensured.

Description

Safety system for railway and highway crossings

Technical field

The present invention relates to safety traffic, particularly provide a kind of safety system in unattended railway and cross-road; The technical matters that it solves is the vehicle and the pedestrains safety problem of Rail Highway four corners.

Background technology

At unattended railway and cross-road, generally only be provided with warning sign at present, do not have guardrail, often, and safety problem occurred because pedestrian and vehicle think little of; Railway and cross-road at Attended mode are provided with guardrail, need manually nurse, and cost is higher; The present invention provides a kind of safety system in unattended railway and cross-road, and automatic guidance has guaranteed the safety at crossing.

Summary of the invention

In view of above-mentioned, main purpose of the present invention is, a kind of safety system for railway and highway crossings is provided, and automatic guidance has guaranteed the safety at crossing.

In order to achieve the above object, the technical scheme that the present invention takes is: erect LED display (2) respectively on highway limit, railway both sides, traffic lights (3), buzzer siren (5) is installed, shock sensor (4) is installed at 100-1000 rice on the rail of both sides, crossing, guardrail track and guardrail (7) and guardrail controller (6) are installed at 1-10 rice, track both sides, crossing, guardrail can be slided on the guardrail track by controller control, whole device is controlled according to the shock sensor signal that is installed on the rail of the left and right sides, crossing by micro controller system (8), electric energy is directly supplied by electrical network, and areas without electricity can adopt solar energy photovoltaic panel or wind power generating set supply; When train will arrive railway and highway crossings, shock sensor detected continuous vibration signal, and signal is passed to micro controller system, Single-chip Controlling LED display shows signal, traffic lights, buzzer siren are reported to the police, and guardrails of both sides is advanced from the trend crossing, and the crossing is sealed; After the train, Single-chip Controlling LED display, traffic lights, buzzer siren stop to report to the police, and guardrail is return original position automatically, has guaranteed vehicle and pedestrian's safety.

Described LED display is a light emitting diode (LED) display screen, can show " RR crossing " printed words when opening at the crossing, can show " block off traffic " printed words when the crossing is sealed.

Described traffic lights are made up of a red light and a green light, and when opening at the crossing, green light is lighted, and when the crossing was sealed, red light was lighted.

Described buzzer siren is the electrical part that can sound, and when the crossing was sealed, buzzer siren sent alarm sound; The also available loudspeaker of this device replace, and when the crossing was sealed, loudspeaker sent the sound of " train has come ".

Described shock sensor is to detect vibration signal, and vibration signal is converted to the device of voltage signal, be installed on the rail of train way, a shock sensor is installed on every rail in 1000 meters far from the crossing in the both sides, crossing, before train approaching crossing, shock sensor detects continuous vibration signal, and signal is passed to micro controller system.

Described guardrail track is installed in each one at 1-10 rice, rail both sides, crossing, and the length of guardrail track is the twice of crossing width, stretches to crossing one side edge.

Described guardrail is the fence that is made of metal, and can adopt board-like fence, also can adopt telescopic fence, can be moved on the guardrail track by driven by motor; Guardrail length is identical with the crossing width; Guardrail moved to the crossing along the guardrail track crossing is sealed when train came, and train guardrail later returns to crossing one side along the guardrail track.

Described guardrail controller is one group of electrical part, can control the rotating of motor under the instruction of micro controller system, guardrail is moved ahead on the guardrail track and retreats.

Described micro controller system is 8 or 16 s' a small-size computer, can carry out computing and information storage.

The present invention is by the shock sensor acquired signal, Single-chip Controlling LED display, traffic lights, buzzer siren, safety barrier, realize unattended railway and cross-road auto alarm, safety barrier automatic switch, guaranteed the safety of pedestrian and vehicle.

Description of drawings

Accompanying drawing is the block diagram of system, among the figure: 1. system power supply, 2.LED read-out, 3. traffic lights, 4. shock sensor, 5. buzzer siren, 6. safety barrier controller, 7. safety barrier, 8. micro controller system

The specific embodiment

At first advance the self check state after system's energising, after self check is finished, when no train passes through, shock sensor detects less than vibration signal, micro controller system just instructs LED display to show " RR crossing " printed words, and green light is lighted, and buzzer phone is not reported to the police, safety barrier is an open mode, and pedestrian and vehicle can pass through the crossing; During near the crossing, shock sensor detects continuous vibration signal as train, and micro controller system just instructs LED display to show " block off traffic " printed words, and red light is lighted, buzzer warning, safety barrier is closed the crossing, this moment pedestrian and vehicle impassabitity crossing; After train passed through, shock sensor detected vibration signal and disappears and put out, and micro controller system instruction LED display shows " RR crossing " printed words, green light is lighted, and buzzer phone stops to report to the police, and safety barrier is return original position, open at the crossing, and pedestrian and open to traffic have guaranteed pedestrian and vehicle safety.

Above embodiment only is a kind of description to embodiment of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention, to distortion and the improvement that technical scheme of the present invention is carried out, all should be within protection domain of the present invention.
