Description

technical field [0001] The invention relates to the field of equipment related to communication vehicles, international classification number H01, and in particular to a centralized management and control system. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of technical level, the proportion of vehicles in people's lives is getting higher and higher, and communication vehicles are widely used in military and civilian fields. Various technologies such as electromechanical and hydraulic are integrated in the communication vehicle. The application of the centralized management and control system of the communication vehicle is the development trend of the industry. It integrates public platform equipment or task equipment into a human-machine interface for monitoring, reduces the difficulty of business development and operation, and improves the use of vehicles. improve the efficiency of vehicles and improve the...

AI Technical Summary

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 is a multi-way reversing valve, such as the prior art figure 1 As shown, the multi-way reversing valve realizes multi-channel control by sliding the spool to switch multiple positions, which can effectively reduce the number of valves, but it has 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 / air, the spool will inevitably mix different media during the sliding process, resulting in the failure of the actuator to work normally

[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.
