Description
Technical Field
The utility model relates to a railway transportation technical field, in particular to railway transportation safety control technique particularly, relates to railway shunting propulsion operation personal safety protection alarm device.
Background
The operation of shunting and propelling a railway is the operation of a locomotive (commonly called a locomotive) to push a train or a vehicle to move. The shunting and propelling operation comprises a propelling coupling operation and a pushing operation, wherein the propelling coupling operation is a process that the locomotive pushes the vehicle to be hooked and connected with another vehicle. Push operations are the process by which a locomotive pushes another vehicle to an operation destination.
In the railway shunting and propelling operation process, the participators mainly comprise a train number worker and a cargo inspector.
Job content of the car number: the method can complete the delivery of train bills, the check of the existing train and the compilation or modification of the train marshalling list safely, correctly and timely, and ensure the safety and the punctuality of the departure of the train.
The operation content of the cargo inspector: checking the current train according to the train formation by the train, wherein the checking content comprises the following steps: vehicle type, vehicle number, sequence, empty weight, tarpaulin, sealing and the like.
Train tickets are handed over and checked in the operation of a train number worker, and the check of a cargo inspector on the cargo load state of the existing train in the operation of the cargo inspector needs to move forward along the train between the station tracks, the train on which one station track stays is checked, and the train needs to pass through the station track when the train is switched to other station tracks or returns to a rest room for rest, and if the train dispatching unit is also operating at the moment, the train number worker and the cargo inspector are rolled by the train on the station tracks possibly to generate safety accidents.
Fig. 4 shows a coupling operation scenario in which the locomotive pushes the vehicles 1, 2, 3 to move along the track, and the vehicles a, B, C are hooked and clasped with each other through the traveling section.
Because the situation of the station track in the advancing area is complex, criss-cross and frequent in shuttling of personnel, in order to avoid safety accidents, in the prior art, a shunting personnel is usually arranged on the side ladder of the last vehicle (vehicle 3) of the train pushed by the locomotive to take the side ladder, the situation on the running line of the vehicle is observed, the personnel is shout to stop when crossing the running line of the locomotive, and an alarm is sent to a driver in case of emergency, so that the driver takes measures for avoiding danger such as braking.
In the shunting propulsion operation, when a locomotive pushes a vehicle to move forwards, although shunting personnel takes over the forefront to watch out, due to the fact that the sight line of the position where the shunting personnel lie prone to take has a blind corner, the shunting personnel have a lot of troubled, the sleeping passengers have insufficient sight lines at night, and the staff passing through the station does not execute the ' one stop, two sees ', three confirms, four passes ' rule and the like, personal safety accidents often occur, serious fruits are caused, and great potential safety hazards exist.
On the other hand, under the current technical conditions, various human body detection alarm devices are mature, for example, the human body detection device disclosed in the chinese patent application No. 201710071708.X adopts a multi-sensor structure, and can detect human body signals within the range of 5-8 m and 160 °. Chinese patent publication No. CN208520499U discloses a technique for detecting a human body by using an infrared temperature sensor and transmitting the detected data to other controlled devices through WIFI.
However, due to the particularities of the railroad shunting operations, the locomotive propelled vehicles are random, sometimes propelling one, sometimes 2 vehicles … …. The human body detection alarm device is arranged at the tail of each vehicle, which obviously causes huge investment and cost, and the alarm devices are redundant once the vehicle completes shunting and propelling operation, so that the capital waste is very large.
