The invention relates to a remote-control system of a stratospheric airship and a control method thereof. The control system is divided to four levels: a decision-making level for executing the selection and switch of a remote-control flight mode according to the actual working state data, and sending a corresponding mode command; a planning level for dynamically planning and generating an airship motor drive command according to the mode command sent by the decision-making level; an executing level for realizing the drive control to an airship motor according to the motor drive command of the planning level; and a perceiving level for finishing the real-time monitoring and data collection of the airship working state, and providing the original data of the airship working state to the decision-making level. The four-level control system architecture design of the control system is capable of simplifying the control device, improving the control efficiency, and fundamentally solving the problems of the function, efficiency and reliability of the near space airship ground and airborne control system.

The application is applied to the field of architecture anti-corrosion technology, and discloses a method, device and equipment for preventing and controlling system architecture corruption, and a storage medium. The method comprises the following steps: acquiring a visual architecture topology graph; the visual architecture topology graph is drawn through a preset graphical editor; the visual architecture topology graph is a logical topology graph corresponding to a distributed application system; acquiring architecture model data based on the visual architecture topology graph; generating rule data corresponding to the distributed application system based on the architecture model data; and performing rule monitoring on business code by using the rule data to determine whether the business code meets the rule data. In this way, the automatic and comprehensive review of the business code is realized by the rule data generated by the architecture model data corresponding to the visual architecture topology graph without depending on the ability of an architect, thereby improving the anti-corrosion effect of the system architecture.

The application discloses a control system design method for space gravitational wave detection. The method first performs modeling on a problem domain of the control system, constructs a first mapping matrix from a functional requirement to a behavior element, performs decoupling verification on the first mapping matrix until the first mapping matrix is in a lower triangular structure. Then, modeling is performed on a solution domain of the control system, a second mapping matrix from the behavior element to a design parameter is constructed, and independence verification is performed on the second mapping matrix until the second mapping matrix is in a lower triangular structure. Finally, a composite equivalent mapping matrix of the two-level matrix is calculated, and is used for change management of the control system. The application can realize formalized design and quantitative evaluation of a strong coupling control system architecture, identify coupling problems in an early design stage, improve design iteration efficiency and change management accuracy, and is mainly applied to control system design for space gravitational wave detection, and can also be applied to design scenes of various high-coupling high-precision space control systems.

A liquid desiccant (LD)-based dehumidification system is provided for heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems. The LD-based dehumidification system includes a tank containing LD, a contact media device including media for being disposed in an air stream to be dehumidified and a sump disposed below the media to receive the LD drained from the media, a pump and valve system for pumping the LD from the tank to the contact media device to wet the media and from the sump to the tank, a heat exchanger through which the LD pumped from the sump to the tank flows, a sensing system for sensing one or more conditions of the LD, and a controller for controlling the pump and valve system in accordance with system status and the one or more conditions of the LD.
