Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technical personnel of the same trade:
Embodiment: as shown in figures 1 and 3, pre-alarm system adopts the central controller of one, realize Train Approaching early warning, railing opening and closing detects, road junction fault alarm, breakdown of equipment self-inspection, the device of the functions such as power supply and battery condition detection is all as the module of in whole pre-alarm system (subsystem), RS232 is passed through between module, RS485 signalling methods obtaining information, the information obtained carries out Logic judgment by central controller, control, report to the police, read-out shows, action button is installed concentratedly on control desk, unified operation, system adopts centrally connected power supply, concentrated alarm.The device of Train Approaching warning function is made up of train approaching sensor, Train Approaching detecting device and Train Approaching forewarn system three part.Train Approaching detecting device and train approaching sensor are separately positioned on first points of proximity (from level crossing distance S1) of train uplink and downlink direction rail, second points of proximity (from level crossing distance S2, and S2<S1).Train Approaching forewarn system carries out accurate acquisition at first points of proximity to train information, and Information Monitoring is as fault alarm limiting safe point again at second points of proximity, and the two covers becoming redundancy each other detect.Whether train information comprises has Train Approaching and judges that This train is bound for XXX by the induction order of sensor.
The device realizing roadway gate opening and closing detection is made up of mercury switch sensor, angular transducer and micro controller system, and detecting device is arranged at the railing place of both sides, level crossing respectively.Wherein, mercury switch sensor and angular transducer are separately positioned on railing and with the receiving end signal of micro controller system and are connected, and the sending end of micro controller system is connected with central controller signal, realizes central controller and by mercury switch sensor and angular transducer, roadway gate open and-shut mode is judged.Mercury switch sensor detects the opening and closing of railing by break-make, and angular transducer is then by its open and-shut mode of railing angle change perception.According to mercury switch sensor initial settling angle degree and break-make response characteristic thereof, as shown in Figure 2, railing angle (α) is provided with the critical angle of φ 1-φ 2 degree, that is:
Railing "On" state: railing is closed gradually by opening, residing angle: α >=φ 1 degree; Railing is opened gradually by closed condition, residing angle: α > φ 2 degree;
Railing " closes " state: railing is closed gradually by opening, residing angle: α < φ 1 degree; Railing is opened gradually by closed condition, residing angle: α≤φ 2 degree; Thus realize the angle being judged railing by mercury switch sensor.
The device realizing road junction fault alarm function is made up of host CPU, recording controller, power management module, communication module and wireless transmitter module, host CPU linkage record controller, power management module is used for the service condition of management devices power supply, and host CPU is connected with the mobile unit signal of train with wireless transmitter module by communication module.
The present embodiment is when specifically using: when road junction fault disables train passage, and crossing management person sends cutoff command by operation to driver, and in case of emergency host CPU can send cutoff command automatically; And when road junction failture evacuation, when allowing train to pass through, crossing management person sends safety instruction by CPU to driver equally, allows it to pass through road junction.This device also has self-checking function, and whether the state carrying out test failure warning by control host CPU is normal.In the specific implementation: the distance parameter that first points of proximity (S1) in Train Approaching detecting device, second points of proximity (S2) compare level crossing is selected, and take crossing safety as setting principle.Arrange uplink and downlink train to leave away sensor at level crossing place, after train rolls road junction away from, sensor sends signal, reminds crossing management person to open roadway gate, open road junction.
This pre-alarm system principle of work is as follows: send a car in front, road junction, forewarn system starts early warning after first points of proximity detect train information by Train Approaching detecting device, the read-out of now central controller shows train uplink and downlink direction, speed the countdown train time of advent (or distance), voice power amplifier simultaneously in central controller constantly reminds crossing management person to make the audio alert information of closing railing, and now crossing management person should close railing in time.When train arrives second points of proximity, forewarn system is by railing open-close detection apparatus automatic discrimination railing open and-shut mode, once railing fault or the personnel crossing gate that causes not on duty is still in open state and certain time, automatic startup separator warning is sent road junction failure alarm signal to driver by system, require that driver is stopped immediately, guarantee level crossing traffic safety.Train is by behind road junction, and System recover is sent a car wait state.
