Description

Detection device for preventing human body from entering non-passing area

Technical Field

The utility model relates to a safety device especially relates to a prevent that human body from getting into detection device in non-current region.

Background

A platform screen door system of a subway rail transit station is an important safety device for guaranteeing the safety of passengers and the normal operation of a subway system. Because certain gaps exist between the subway train door and the platform screen door as well as between the train and the platform, the gaps are non-passing areas. However, at the peak time, since there are many passengers, during the process of getting on or off the train, people may enter the non-passing area between the train and the screen door for various reasons, thereby causing unexpected safety accidents. In order to solve the above problem, some subway companies may set a yellow warning strip on the inner side of the screen door to achieve a warning effect, but the mode cannot really prevent people from intentionally entering the non-passing area.

The utility model provides a technical scheme that its technical problem adopted is: the detection device for preventing the human body from entering the non-passing area comprises a controller and a plurality of tof distance meters, wherein the tof distance meters are installed on a door frame of a shielding door and face the direction of a train; the controller is arranged in the upper cover plate of the shielding door or in the side box electric appliance box; the controller is respectively connected with the warning device and the plurality of tof distance measuring instruments; the tof range finder is used for detecting a real-time gap between the shielding door and the train; and the controller compares the real-time gap with a preset reference gap and controls the warning device to give an alarm when the real-time gap is smaller than the preset reference gap.

The plurality of tof distancers are vertically and equidistantly installed on a door frame of the shielding door.

The number of the tof distance measuring instruments is more than or equal to 3.

The highest mounting height of the tof distance measuring instrument is 180 cm.

The warning device comprises a warning lamp and a loudspeaker.

The controller is further connected with a subway signal system, the subway signal system transmits the train entering information and the train exiting information to the controller, the controller controls the tof distance measuring instrument to be started after receiving the entering information, and controls the tof distance measuring instrument to be closed after receiving the exiting information.

Advantageous effects

Since the technical scheme is used, compared with the prior art, the utility model, have following advantage and positive effect: the utility model discloses an at the inboard tof distancer of installing towards the train setting of shield door, utilize this tof distancer can detect the real-time clearance between train and the shield door, then indicate to have the foreign matter between shield door and the train when this real-time clearance is less than when predetermineeing the benchmark clearance to avoid the incident to take place. The utility model provides a controller still links to each other with subway signal system, can accurately learn the train through subway signal system and get into and out of station to open the tof distancer when getting into station, close the tof distancer when going out of station, thereby reduce the consumption.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications can be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The embodiment of the utility model relates to a detection device for preventing human body from entering into non-passing area, as shown in fig. 1 and fig. 2, comprising a controller 1 and a plurality of tof distance meters 2, wherein the tof distance meters 2 are arranged on the door frame of a shield door 3 and face to the direction of a train 4; the controller 1 is arranged inside an upper cover plate of the shielding door 3; the controller 1 is respectively connected with the warning device and the plurality of tof distance measuring instruments 2; the tof distance measuring instrument 2 is used for detecting a real-time gap between the shielding door 3 and the train; and the controller 1 compares the real-time gap with a preset reference gap and controls the warning device to give an alarm when the real-time gap is smaller than the preset reference gap. Wherein, the quantity of tof distancer 2 is greater than or equal to 3, and the quantity of tof distancer is more, detection device's monitoring precision is higher. In the present embodiment, the number of tof distance meters 2 is 4. In order to avoid blind spots, a plurality of tof distance meters can be preferably vertically and equidistantly mounted on a door frame of the shielding door, so that any foreign matter in the vertical direction can be detected, and the highest mounting height of the tof distance meters in the embodiment is 180 cm. It is worth mentioning that when the station is a half-height station, the controller in the embodiment may be installed in the side box electrical box.

the working principle of the tof range finder is as follows, a laser transmitter of the tof range finder emits laser, a laser receiver of the tof tester receives the laser returned by an object, and the distance between the object and the tof range finder can be obtained by multiplying the time difference by the light speed. Based on above-mentioned theory of operation, in this embodiment, under normal conditions, install the tof distancer on the door frame of shield door and can survey a distance value, this distance value is the distance value that obtains after the laser that the tof distancer launched is beaten on the train door, and in the middle of the relative motion process of the relative shield door body of the train door body, this distance value has certain change, but has a threshold value, can set up one according to this threshold value and predetermine the benchmark clearance. When someone wants to get into the non-passing region between train and the shield door, because the gap between train and the shield door is originally not big, the human body must hug closely the shield door and just can get into, therefore the tof distancer will record a real-time clearance that is less than preset benchmark clearance far away, just so can judge someone and get into. The more tof range finders are installed, the more triggered signal sources are, and the higher the accuracy of alarm judgment is.

The warning device in the embodiment comprises a warning lamp and a loudspeaker, when the controller judges that foreign matters enter the non-passing area, the warning lamp can flash, and the loudspeaker can buzz, so that the warning is performed through sound and light.

The controller in the embodiment is further connected with a subway signal system, the subway signal system transmits the train entering information and the train exiting information to the controller, the controller controls the tof distance measuring instrument to be started after receiving the entering information, and controls the tof distance measuring instrument to be closed after receiving the exiting information. By the method, the detection can be ensured only under the condition of a train, and the power consumption of the whole detection device is reduced. The controller in this embodiment can be implemented by a 51-series single chip microcomputer, and only needs to have a comparison function and a signal receiving and signal sending control function.

The utility model discloses an at the inboard tof distancer of installing towards the train setting of shield door, utilize this tof distancer can detect the real-time clearance between train and the shield door, then indicate to have the foreign matter between shield door and the train when this real-time clearance is less than when predetermineeing the benchmark clearance to avoid the incident to take place. The utility model provides a controller still links to each other with subway signal system, can accurately learn the train through subway signal system and get into and out of station to open the tof distancer when getting into station, close the tof distancer when going out of station, thereby reduce the consumption.
