Detailed Description
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the following specific embodiments.
The stock way refers to a track with a number in the garage. A garage contains several tracks. When a rail vehicle enters and exits the garage, people near the track are likely to not hear the whistle of the rail vehicle due to interference from other mechanical devices. In addition, because the whistling sounds entering and exiting the garage are not different, when a person is faced with the railway vehicle, whether the railway vehicle is approaching or not cannot be known.
In order to solve the technical problems, as shown in fig. 1, the utility model provides a rail vehicle track occupation judging and alarming system, which comprises a plurality of judging and alarming units, wherein one judging and alarming unit judges and alarms rail vehicles on one track; the judgment alarm unit comprises:
The vehicle access sensor is used for sensing that the railway vehicle enters and exits the garage; in this embodiment, the in-out sensor is an eddy current sensor installed at two sides of the rail at the garage door, and the eddy current sensor can sense the travelling direction of the wheel set of the rail vehicle. The two sides of the rail at the garage door are respectively provided with an eddy current sensor, one is used for warehouse-in induction of the rail vehicle, and the other is used for warehouse-out induction of the rail vehicle.
A pass sensor for detecting whether the rail vehicle passes through the garage door completely; in this embodiment, the passing sensor is a photoelectric switch arranged at two sides of the garage door, and whether the railway vehicle passes through the garage door completely is judged by on-off of the photoelectric switches. When the railway vehicle passes through the garage door, light rays between the photoelectric switches are blocked; when the railway vehicle completely passes through the garage door, the light rays between the photoelectric switches are restored to be communicated.
The alarm is used for alarming and reminding a worker of paying attention to whether the railway vehicle enters or exits; in this embodiment, the alarm is an audible and visual alarm, and the audible and visual alarm gives out different alarms when the railway vehicle enters and exits. For example, when a railway vehicle goes out of a warehouse, the audible and visual alarm can use a stroboscopic yellow warning lamp and simultaneously perform voice broadcasting: note that xx tracks have rail cars coming out of stock. Of course, the content of the voice broadcast can be adjusted according to the actual use condition.
The analysis module is used for analyzing the running direction of the railway vehicle according to the data acquired by the in-out sensor and controlling the alarm to give out a corresponding alarm; and meanwhile, whether the railway vehicle completely passes through the garage door is analyzed according to the data acquired by the sensor, and the alarm is controlled to stop alarming when the railway vehicle completely passes through the garage door.
In this embodiment, the system further includes a sub-control box for collecting the in-out sensor and the sensor signal, and each sub-control box controls two judgment alarm units. In addition, the analysis module is a comprehensive control box, and the sub-control box is controlled by the comprehensive control box; the integrated control box may communicate with a superior management system. And a PLC controller, an HMI and a TCP communication module are arranged in the comprehensive control box, and the communication module is used for carrying out data interaction with the upper management system.
When a rail vehicle is put in storage, the system executes the following procedures:
1) The method comprises the steps that an eddy current sensor responsible for warehouse-in detection of a railway vehicle senses an incoming signal of the railway vehicle at first and transmits the signal to a comprehensive control box;
2) The analysis module diagnoses the warehousing action, and executes a warehousing alarm prompt instruction;
3) Starting an audible and visual alarm function (the audible alarm content supports custom voice);
4) Judging the state of the photoelectric switch, and continuously alarming if the photoelectric switch is in a blocking state; if the communication state is in the communication state, the audible and visual alarm is turned off after the time delay is 5s (can be set);
When the railway vehicle goes out of the warehouse, the flow executed by the system is similar to the flow in the warehouse.
When the railway vehicle is parked on the track, the vehicle body stops the photoelectric switch for a long time, the system can start an alarm overtime mechanism, default overtime alarm time is 1 minute (can be set), overtime automatically closes the audible and visual alarm, and clears the corresponding ground sensor state bit.
When the rail vehicle repeatedly creeps on the level crossing, the system can continuously alarm until the rail vehicle leaves the area, and the sensor state is restored to the initial state.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that the above-mentioned preferred embodiment should not be construed as limiting the utility model, and the scope of the utility model should be defined by the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
