Description
Technical Field
The utility model relates to a tram platform safety line intrusion alert system.
Background
With the development of urban rail transit, tramcars have been continuously operated in a plurality of cities, but the problem of passenger transport safety guarantee is increasingly severe with the increase of passenger flow. At present, most tramcar platforms are semi-closed, only guardrails are used for partial separation, and boarding and alighting spaces are reserved. At present, when a tramcar drives to a station, partial passengers waiting at the station sometimes cross a yellow warning line of the station, so that great potential safety hazards exist when the tramcar enters the station. Nowadays, most tramcar project operations are managed and controlled and stopped by means of manual supervision, and sometimes supervision dead corners are caused by more people at a platform. Some subways adopt infrared grating sensors, but the scheme has high input cost and is greatly influenced by the environment.
SUMMERY OF THE UTILITY MODEL
In order to solve a difficult problem in the prior art, the utility model provides a tram platform safety line intrusion alert system.
The purpose of the utility model is realized through the following technical scheme:
the intrusion alarm system for the safety line of the tramcar platform comprises pressure-sensitive equipment arranged on the safety line of the platform, induction sensors respectively arranged at the head end and the tail end of the platform and sound-light alarm equipment connected with the pressure-sensitive equipment.
Preferably, the induction sensor is an infrared induction photoelectric sensor arranged in the control host.
Preferably, the pressure-sensitive devices are arranged in an array along the head-to-tail direction of the platform, and the pressure-sensitive devices comprise pressure-sensitive adhesive tapes attached to the ground of the platform.
Preferably, the audible and visual alarm device comprises an audible and visual alarm, a communication module and an a/D converter, the audible and visual alarm is connected with the input end of the a/D converter, and the a/D converter is connected with the communication module through a processor.
Preferably, the number and the positions of the audible and visual alarms correspond to the number and the positions of the pressure-sensitive tapes in the pressure-sensitive equipment.
Preferably, the control host is connected with the pressure-sensitive device, the control host further comprises an a/D converter connected with the pressure-sensitive device, and the a/D converter is connected with the communication module through the processor.
The beneficial effects of the utility model are embodied in: adopt the utility model discloses an alarm system, prevention that can be fine, avoid the platform to wait the passenger and invade the rail and go the district, really ensure the platform personnel's safety of waiting, the cost of labor that saves that simultaneously also can be fine.

Detailed Description
The technical scheme of the utility model is specifically explained below in combination with the embodiment, the utility model discloses a tram platform safety line intrusion alert system combines figure 1 to show, including set up in the pressure-sensitive equipment 1 of platform safety line, set up respectively in the first, terminal induction sensor 24 of platform and with the audible-visual alarm equipment 3 that pressure-sensitive equipment 1 is connected. The induction sensor is an infrared induction photoelectric sensor arranged in the control host 2. The control host 2 is connected with the pressure-sensitive device 1, the control host 2 further comprises a host A/D converter 21 connected with the pressure-sensitive device 1, and the host A/D converter 21 is connected with a host communication module 23 through a host processor 22. The control host and the sound and light alarm device are arranged in the same local area network, and the communication module 33 is electrically connected with the host communication module 23.
Because the platform is longer, for better, more reasonable monitoring, the pressure sensitive equipment is arranged along the first and last direction of platform in array. The pressure sensitive device includes a pressure sensitive tape affixed to the platform floor. The audible and visual alarm device comprises an audible and visual alarm 32 corresponding to the pressure-sensitive device, an A/D converter 34 connected with the audible and visual alarm 32, a processor 31 connected with the A/D converter 34, and a communication module 34 connected with the processor 31.
The correspondence described above means that the number and position of the audible and visual alarms 32 correspond to the number and position of the pressure-sensitive tapes in the pressure-sensitive device 1. When the audible and visual alarm 32 at a certain position gives an alarm, whether the passenger invades the specific position or not can be quickly monitored and corresponded.
The following brief description of the invention discloses a detection alarm principle:
before the train enters the station, the whole system is kept open, if a platform waiting personnel invades a safety line to trigger a corresponding pressure-sensitive adhesive tape in the pressure-sensitive device 1, a pressure-sensitive signal is generated between two electrodes corresponding to the pressure-sensitive adhesive tape, the signal passes through the host A/D converter 21, an analog signal is converted into a digital signal and then is transmitted to the host processor 22, and when the digital signal exceeds a preset value, an instruction is sent to the host communication module 23. Meanwhile, the host communication module 23 and the communication module 33 are networked, the processor 31 carries out information processing, and after the corresponding position is judged to be triggered, the information is transmitted to the corresponding audible and visual alarm 32 through the A/D converter 34 to remind passengers in the intrusion safety line to evacuate.
When the train enters the station, the infrared sensing photoelectric sensor at the start end of the station is triggered, and the whole system is closed after the infrared sensing photoelectric sensor is confirmed by the host processor 21. During this time, passengers getting on and off the vehicle do not trigger the system circuit. When the train leaves the platform, the infrared sensing photoelectric sensor of the platform terminal is triggered, and the rectification system is started after the confirmation of the infrared sensing photoelectric sensor by the host processor 21.
Of course, the present invention has many specific embodiments, which are not listed here. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
