In the figure, 1, a maintenance area; 2. a monitoring area; 3. fixing the pile; 4. an image pickup apparatus; 5. a first laser range finder; 6. an acousto-optic device; 7. a laser scanner; 8. an isolation device; 9. a second laser rangefinder; 10. a controller; 11. a railing.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1 to 3, the utility model discloses a EMUs overhaul storehouse with alarm system, including overhaul district 1 and the monitoring area 2 of establishing at the entrance of overhaul district 1, as shown in fig. 2, overhaul storehouse 1 and monitoring area 2 keep apart with railing 11, the both ends angle of the outside end of monitoring area 2 sets up two spud piles 3, install camera equipment 4 on the spud pile 3, first laser range finder 5 and acousto-optic device 6, preferably, acousto-optic device 6 is stereo set and warning light, or loudspeaker, the acousto-optic device combination of ground lamp and rotatory alarm lamp etc..

The monitoring area 2 is a level crossing at the entrance of the maintenance area 1, a laser scanner 7 is arranged at one end angle of the outer side end of the monitoring area 2, and isolation devices 8 are arranged on two sides of the monitoring area 2; and a second laser range finder 9 is arranged on the side wall of the inner side end of the monitoring area 2.

The image pickup apparatus 4, the first laser rangefinder 5, the acousto-optic device 6, the laser scanner 7, the isolation device 8 and the second laser rangefinder 9 are respectively connected with a controller 10, preferably, the controller 10 is a PLC controller. In fig. 2, the controller 10 is located on the back side of the door of the service depot, not shown.

Camera equipment 4, first laser range finder 5 and acousto-optic device 6 pass through 3 installation settings of spud pile, can monitor and effectively remind in

monitoring area

2 and 1 entrance in maintenance area all around. The camera device 4 is used for monitoring the fortification area of the monitoring area 2 for 24 hours and capturing pedestrians and vehicles illegally intruding into the dangerous area after receiving the laser scanner; the first laser range finder 5 is used for entering a vehicle when the vehicle is received, detecting the coming vehicle and reminding the driver of clearing the field in the monitoring area 2; when the motor train unit is taken out of the garage, the fact that the motor train unit is taken out of the garage is proved. The second laser distance measuring instrument 9 is used for detecting that a vehicle passes through when the vehicle is delivered out of the garage; and when the vehicle is put in storage, the vehicle cannot be detected to prove that the vehicle is put in storage.

Laser scanner 7 can carry out real time monitoring to monitoring area 2, can carry out regional setting of taking precautions against, interface setting, communication setting etc. the normal output alarm signal of system of being convenient for. When detecting that an object is left in the monitoring area 2 or a pedestrian or a motor vehicle intrudes illegally in the security danger area, an alarm signal is sent out to inform the controller 10 to carry out scheduling and processing, sound and light reminding is sent out, and the isolating device returns to the original position. Meanwhile, the laser scanner 7 can detect that if someone approaches or crosses the track during the process of entering and leaving the motor train unit, snapshot and record illegal approaching or crossing track events for later reference.

The isolation device 8 is used for isolating and protecting the inside and the outside of the monitoring area 2 of the level crossing by utilizing the isolation device when the motor train unit needs to go out of or enter the garage when an operator receives or sends the motor train unit, and the isolation device 8 can be a lifting rod. After receiving the detection signal in the monitoring area 2, the controller 10 automatically sends out a vehicle sending or receiving ending signal, the ground lamp, the rotary alarm lamp and the horn alarm prompt stop, and the vehicle receiving alarm mode ends.

If the sound-light alarm is carried out on the personnel crossing the track bridge, the personnel coming and going at the level crossing or the motor vehicles in advance by matching the reserved interface signal with the PLC or other systems through the access signal system, the danger of personal harm to the working personnel can be avoided, and the personal safety of the working personnel is improved.

The potential safety hazard caused by the fact that the existing far infrared grating is only a line for fortification and cannot completely cover the whole dangerous area and people or objects are out of the detection range of the grating and cannot be identified in the dangerous area is solved. The problem of false alarm caused by strong light or displacement of the existing grating is solved. The shooting device is linked with the camera device 4 to carry out violation snapshot, so that the violation personnel can be checked and evidence can be obtained conveniently in the later period, and the violation personnel are subjected to frightening effect.

The laser surface scanner detects that a pedestrian or a motor vehicle dangerous area illegally intrudes into the dangerous area, and outputs an alarm signal to enable the isolation device 8 to return to the original position in time after receiving the alarm signal, so that the person or the object is prevented from being blocked in the dangerous area.

The specific embodiments of the present invention are only for explaining the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications to the present embodiment as required without inventive contribution after reading the present specification, but all the embodiments are protected by patent laws within the scope of the claims of the present invention.
