Problems solved by technology

[0003] At present, the parking brake is generally released by controlling the hand brake valve, and when the parking brake cannot be released by the hand brake valve, a manual wrench is usually used to loosen the nut on the top bolt of the composite spring brake air chamber to release it. This process is very tedious and time-consuming
[0004] However, the airport shuttle bus runs between the terminal building and the aircraft at a remote stand, and the airport shuttle bus may accidentally park between the terminal building and the aircraft at a remote stand, and suddenly the hand brake valve cannot quickly release the parking brake. The shuttle bus cannot be towed away from the scene quickly, which may lead to accidental danger

Abstract

The invention provides a safety system of an airport shuttle bus. The safety system comprises an inflating and deflating mechanism and a control mechanism. The inflating and deflating mechanism comprises an air storage barrel, a hand brake valve, a first electromagnetic valve, a quick release valve, a brake air chamber and a deflation valve. The control mechanism comprises a signal sensor and a controller, wherein the controller is used for receiving a driving state signal and a bus door state signal from the sensor and sending out corresponding control signals according to the driving state signal and the bus door state signal. The control mechanism further comprises an emergency brake relieving switch, and when the sensor senses the fact that the airport shuttle bus is in a parked state and a bus door is in a closed state while the emergency brake relieving switch is turned on, the controller sends out a second control signal to enable the first electromagnetic valve to be switched into a normally-open state and the deflation valve to be switched into a normally-closed state, so that the brake air chamber is inflated with air in the air storage barrel through the first electromagnetic valve and the quick release valve, and brake of the airport shuttle bus is relieved.

Description

technical field [0001] The invention relates to an airport shuttle bus, in particular to an airport shuttle bus safety system. Background technique [0002] The airport shuttle bus shuttles boarding and disembarking passengers between the terminal building and the aircraft with remote stands, and is applicable to the aprons and places of various civil aviation airports. The airport shuttle bus shuttles the boarding and disembarking passengers between the terminal building and the plane with a remote stand. [0003] At present, the parking brake is generally released by controlling the hand brake valve, and when the parking brake cannot be released by the hand brake valve, a manual wrench is usually used to loosen the nut on the top bolt of the composite spring brake air chamber to release it. This process is tedious and time-consuming. [0004] However, the airport shuttle bus runs between the terminal building and the aircraft at a remote stand, and the airport shuttle bu...
