Embodiment approach

[0152] A possible implementation manner, step S223 specifically includes:

[0153] S223a. Select a gear between the transition gear and the current gear as the first intermediate gear. Among them, for one of the number of openings of the combustion head and the fuel injection pressure of the combustion head, the first intermediate gear and the transition gear are the same as the current gear; for the other of the number of openings of the combustion head and the fuel injection pressure of the combustion head, the transition The gear, the first intermediate gear and the current gear are in a decreasing or increasing relationship.

[0154] S223b. Adjust the other one of the number of openings of the combustion head and the fuel injection pressure of the combustion head, so as to switch from the current gear to the first intermediate gear.

[0155] S223b. Adjust the other one of the number of openings of the combustion head and the fuel injection pressure of the combustion head,...

Abstract

The invention discloses a heater control method, a heater and a deicing vehicle, and the method comprises a fuzzy control stage, a gear switching stage and a neural network control stage which are sequentially carried out. The fuzzy control stage comprises: determining the first temperature of liquid and the flow of the liquid in unit time; obtaining a preset set temperature; determining a targetgear of the heater according to the first temperature, the flow and a set temperature. The gear switching stage comprises: switching the current gear to the target gear according to the preset numberof opened combustion heads corresponding to each gear and the preset combustion head oil injection pressure. The neural network control stage comprises: obtaining the flow of the liquid in unit time,and inputting the flow into a neural network to determine a heating period, wherein the heating period is a time value for liquid to enter from the inlet end of the heater and flow out from the outletend of the heater. The control method of the heater, the heater and the deicing vehicle have the advantage of being stable in liquid temperature.

Description

technical field [0001] The present application relates to a deicing vehicle, in particular to a heater control method, a heater and a deicing vehicle. 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. In the process of deicing operation...
