Description
Technical Field
The invention relates to the technology of airport ground service vehicle running control, in particular to an airport electric vehicle automatic machine-to-machine speed-limiting system and a speed-limiting method.
Background
At present, airport vehicles run mainly through a driver according to instructions of a ground leader, and when approaching an aircraft, the speed of the vehicles is controlled to brake or decelerate mainly by judging distance and speed according to the experience of the driver so as to prevent the vehicles from colliding with the aircraft, thereby avoiding vehicle-making accidents or economic loss. Because the cost of the airplane is high, and after the collision, in order to eliminate the hidden danger of the flight, the airplane needs to be comprehensively checked, and the minor damage also adopts remedial measures such as maintenance and the like, so that the serious economic loss and the hidden danger of the flight exist. Therefore, the requirement for the driving skill of the airport driver is high, and the training and simulation training needs to be performed for a long time, and the labor cost is high. In order to reduce the requirement of driving skill and reduce labor cost, an automatic speed-limiting system for the electric vehicle for the airport needs to be developed.

By adopting the speed limiting system of the technical scheme, the vehicle utilizes the speed limiting controller and the hydraulic auxiliary braking system to control running and braking, and can approach to the aircraft at different running speeds by monitoring the gradual distance from the target object aircraft, for example, when the distance is longer, the running speed can be relatively higher, and the running speed can be slower when the distance is closer to the aircraft, and when the distance is close to a proper position, for example, the distance is determined according to the safety distance requirements of various docking facilities carried by the vehicle and the aircraft, so that the collision accident between the vehicle and the aircraft can be effectively avoided, the operating skill requirement of a driver is reduced, and the labor cost is reduced. The speed limiting controller calculates the vehicle running speed by combining time factors through the change of the distance between the vehicle and the aircraft to obtain the vehicle running speed, or receives the vehicle running speed data and data between the vehicle and a target aircraft through an input interface, compares the distance and speed input data with a set value by using an internal comparison circuit to run by adopting a preset running speed strategy or perform parking braking in a corresponding distance range, and controls the running speed and the distance through the controller and a hydraulic auxiliary braking system when the running speed is not matched with the set value of the distance. When the speed-limiting controller adopts the scheme that the OBD interface of the vehicle is connected with the vehicle control unit of the vehicle, the speed-limiting controller not only can carry out running control on the vehicle, but also can obtain the running speed data of the vehicle and the required power supply by utilizing the OBD interface; when the vehicle is provided with a cigarette lighter interface, the controller can also obtain a power supply by utilizing the cigarette lighter interface of the vehicle; of course, the controller may also be self-contained with a separate power source. The vehicle control unit is integrated with a conventional vehicle running control system.

Preferably, the speed limit controller is also provided with a warning unit. The warning signal is provided through the warning unit, a vehicle driver is reminded of concentrating on driving, and safety is improved.
Further preferably, the warning unit comprises a light alarm and an audio alarm. By using the acousto-optic combined alarm mode, the alarm signal can be reliably transmitted to the driver, and the driving safety is further improved.
Preferably, the operation panel of the speed limit controller is mounted on an instrument desk of a vehicle cab. The driver can operate and control conveniently, and the driving safety is improved.
In order to achieve the second object, the invention adopts the following technical scheme.

Further ensuring the safety of the aircraft.
Preferably, when the distance between the electric vehicle and the aircraft is less than or equal to 2m, the speed limit controller performs double warning of light and audio by using the warning unit. The reliability of warning is improved through multiple warning modes in the dangerous distance. To further ensure safe approach of the vehicle to the aircraft, it is preferable to perform deceleration control again at this time, thereby further reducing the vehicle speed.
The invention has the advantages that the speed-limiting system can realize speed-limiting driving of the vehicle, ensure that the vehicle approaches to an aircraft at a safe driving speed and brake the vehicle within a safe distance. The speed limiting method is realized based on a speed limiting system, and the safety of the aircraft is ensured by warning in a distance limiting mode and a multiple warning mode within a dangerous driving distance.
