Embodiment 1

[0037] see figure 1 , which is a schematic diagram of Embodiment 1 of the safety monitoring system for boarding bridge lifting provided by the present invention.

[0038] The boarding bridge lifting safety monitoring system provided in this embodiment includes: a displacement sensor 101, a controller 102 and a relay 103;

[0039] The normally closed contacts of the relay 103 are connected in series in the emergency stop button circuit of the lifting control module of the boarding bridge;

[0040] The displacement sensor 101 is arranged on the boarding bridge for detecting the height of the boarding bridge to the ground, and sending the height to the controller 102;

[0041] It can be understood that the displacement sensor 101 detects the absolute height of the boarding bridge to the ground, and the current displacement sensor 101 can output an analog signal of a standard range. For example, the output height is represented by a current signal, and the range of the current si...

Embodiment 2

[0055] see figure 2 , which is a schematic diagram of Embodiment 2 of the safety monitoring system for boarding bridge lifting provided by the present invention.

[0056] It should be noted that the controller in the monitoring system provided by the present invention may be a microprocessor, such as a single-chip microcomputer or DSP, or may be a programmable logic controller (PLC).

[0057] In this embodiment, the controller is taken as an example for introduction. For example, Siemens S7300 series PLC can be used.

[0058] It should be noted that the PLC includes a memory, the height reference value can be stored in the memory, and the height of the boarding bridge detected each time can also be stored in the memory.

[0059] The displacement sensor 101 outputs the height of the analog signal to the PLC102;

[0060] The PLC 102 obtains the predetermined normal height range in advance.

[0061] Specifically, the PLC102 obtains the predetermined normal height range in ad...

Embodiment 3

[0070] see image 3 , which is a schematic diagram of Embodiment 3 of the boarding bridge lifting safety monitoring system provided by the present invention.

[0071] In addition, the boarding bridge lifting safety monitoring system provided in this embodiment also includes: a host computer 104 and an audible and visual alarm module 105;

[0072] The controller 102 is further configured to send an alarm message to the host computer 104 when the altitude exceeds the predetermined normal altitude range;

[0073] The host computer 104 is configured to notify the duty personnel in the duty room after receiving the alarm information;

[0074] The controller 102 is also used to control the contact of the alarm relay to close when the height exceeds the predetermined normal height range, so that the sound and light alarm module 105 will give an alarm; the sound and light alarm module 105 is connected with the The contacts of the alarm relay described above are connected in series. ...

Abstract

The invention provides an aircraft boarding bridge ascending and descending safety monitoring system. The aircraft boarding bridge ascending and descending safety monitoring system comprises a displacement sensor, a controller and a relay. The normally-closed contact of the relay is connected into a scram button loop of an ascending and descending control module of an aircraft boarding bridge in series. The displacement sensor is arranged on the aircraft boarding bridge and used for detecting the height, relative to the ground, of the aircraft boarding bridge and sending the height to the controller. The controller is used for comparing the height with a preset normal height range and controlling the normally-closed contact of the relay to be disconnected when the height exceeds the preset normal height range so as to cut off a total power supply of the aircraft boarding bridge. The use state of the aircraft boarding bridge can be detected, and alarming and stopping can be performed in time when uncontrolled descending or ascending occurs. Thus, the safety of an aircraft and personnel is ensured.

Description

technical field [0001] The invention relates to the technical field of aviation safety equipment, in particular to a safety monitoring system for boarding bridge lifts. Background technique [0002] The boarding bridge, also known as the air bridge or the boarding bridge, is a facility in the airport terminal building that extends from the boarding gate to the aircraft cabin door to facilitate passengers to enter and exit the cabin. [0003] Before the advent of the boarding bridge, passengers had to walk on the asphalt road at the same height as the ground, and then climb up the mobile boarding ladder. At present, this boarding method is still used in most airports in the world, but usually it can only accommodate small aircraft small airport. [0004] In all weather conditions, the use of the bridge allows passengers to board and disembark without being exposed to the sun or rain. Its head end is fixed on the central axis at the boarding gate, the bridge body can move le...
