Abstract

The invention relates to a working method of a vehicle-mounted heating control system; the method comprises a power conversion method, a temperature adjusting method and an integrated valve heating method. The power supply conversion method comprises the steps that the power supply comprises a storage battery, a power supply conversion circuit is arranged at the output end of the storage battery, and the power supply conversion circuit converts a 24-V voltage into a 5-V voltage and provides the 5-V voltage to a main controller; the temperature adjusting method comprises the steps that the heating power is adjusted through a temperature adjusting circuit, a temperature sensor is arranged on an oil tank, the temperature sensor senses the temperature of the oil tank and sends a signal to the main controller, the main controller sends a control signal to a single-chip microcomputer, the single-chip microcomputer controls the temperature adjusting circuit to adjust the power output to the heater so as to adjust the heating temperature.

Description

technical field [0001] The invention relates to the field of equipment related to communication vehicles, the international classification number is H01, and in particular relates to a working method of a vehicle heating control system. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of technological level, the proportion of vehicles in people's life is getting higher and higher, and communication vehicles are widely used in military and civilian fields. Communication vehicles integrate various technologies such as electromechanical hydraulics. The application of centralized management and control systems for communication vehicles is an industry development trend. It integrates public platform equipment or task equipment into a human-machine interface for monitoring, reducing the difficulty of business operations and improving vehicle usage. Improve the efficiency of the vehicle and improve the intelligence and...

Problems solved by technology

[0005]1. During the heating process of the fuel tank of the communication vehicle in the prior art, the fuel heater sends warm water or warm air to heat the fuel tank. At this time, corresponding valves are required to control; at the same time, the oil output in the oil tank also needs to be controlled by valves. Too many valves will lead to too many devices, resulting in difficulties in layout and undesired space occupation

[0006] 2. In the fluid control of the prior art, there are multi-way reversing valves, such as the prior art As shown in Figure 1, the multi-way reversing valve realizes multi-way by sliding the spool to switch multiple positions The control can effectively reduce the number of valves, but there is a premise that the fluids are from the same source. For example, the reversing valve only controls the multi-channel operation of oil, and for different media such as oil / water, such as oil / gas, the spool During the sliding process, it is inevitable that different media will be mixed, causing the execution end to fail to work properly

[0007]3. The fuel heater in the prior art only heats the fuel tank, but other places that are prone to liquid accumulation, such as inside the valve, also need to be heated. But there is no corresponding solution in the prior art

[0008]4. In the circular channel and small-sized channel of the prior art, it is difficult to control the on-off of the channel. If the circular shape and smaller size are to be controlled On-off often increases a lot of cost

[0009] 5. The reversing valves and multiple valves in the prior art can only realize one pass and one close (such as orthogonal multiple valves, reversing valves) or simultaneously pass break (such as parallel multi-valve), did not realize the function of multiple working states

[0010]6. In the prior art, when the spool is closed by spring force, there is insufficient spring force, which cannot be solved well

[0011]7. The fuel heater in the prior art is controlled locally through the built-in wire control switch panel, and cannot be connected to the centralized management and control system of the vehicle for unified monitoring. The vehicle environment control system is intelligently connected and automatically switches, adjusts the temperature, and adjusts the flow rate according to the vehicle environment.
