Problems solved by technology
[0003] The deicing vehicles currently used in airports are usually instant heat type. During the deicing operation, the deicing fluid is heated from the ambient temperature to the predetermined temperature before the aircraft can be deiced; according to the needs of the workload, the deicing The heater of the car needs to change gears to change the fuel injection pressure of the combustion head and the number of openings of the combustion head to obtain different heating effects. During the gear shifting process, the flameout phenomenon may occur, which will cause the deicing vehicle to be damaged due to insufficient temperature. Poor deicing effect or interruption of deicing operation, affecting efficiency

The present application discloses a control method, a control system, a heater and a deicing vehicle for a deicing vehicle heater, including: obtaining the number of openings of the combustion heads of the current gear and the fuel injection pressure of the combustion heads; obtaining the combustion head of the target gear The opening number and the fuel injection pressure of the combustion head; wherein, the current gear and the target gear have at least different opening numbers of the combustion head; switch from the current gear to the target gear according to preset control rules; the The preset control rule is as follows: among the various gears in the switching process, one of the injection pressure of the combustion head and the number of openings of the combustion head in two adjacent gears is the same, and the other is different. The control method, control system, heater and deicing vehicle of the present application can effectively prevent flameout.
Description
technical field [0001] The application relates to a deicing vehicle, in particular to a control method, a control system, a heater and a deicing vehicle heater. Background technique [0002] Under icing conditions, ice, snow, and frost will have a direct impact on the operational safety of the aircraft. They will roughen the outer surface of the aircraft, increase the weight of the aircraft, limit the range of movement of the aircraft control surfaces, and cause instrument errors. Increased aircraft stall speed and instantaneous abnormal pitching will greatly reduce the flight performance of the aircraft, especially when the aircraft takes off and ascends, it will make the flight attitude difficult to control, and even cause air crashes. Therefore, in order to ensure normal shipping and flight safety, the frost and snow on the surface of the aircraft must be removed. [0003] The deicing vehicles currently used in airports are usually instant heat type. During the deicing o...
