The application relates to the technical field of modular cabin temperature control, and discloses an integrated thermal management system for a modular steel cabin and a control method thereof, the system comprising a main refrigerant circuit, a human cabin water circulation circuit, a plate heat exchanger coupling the two, a fluorine path electromagnetic valve arranged on a refrigerant pipeline leading to the plate heat exchanger, and an intelligent controller, the core of which is that the intelligent controller is configured to, when the system is in a refrigeration mode and it is judged that the human cabin temperature demand has been met while the equipment cabin has a heat dissipation demand, execute cooperative control: keeping the compressor in the main refrigerant circuit running while closing the fluorine path electromagnetic valve. Through the above-mentioned cooperative control logic, the refrigeration capacity is dynamically transferred from the human cabin which has met the demand to the equipment cabin, the compressor is prevented from frequently starting and stopping, the energy utilization efficiency and system operation stability are significantly improved on the basis of not increasing the hardware cost, and the system structure is simplified.

The application discloses a kind of detection methods of engine valve lock block missing loading, it is related to engine assembly detection technical field, including using the inherent gap between two valve lock pieces when normal assembly as fixed leakage passage, by machine tool drive semi-automatic plugging down, plugging rubber ring and valve spring seat are adhered to form detection cavity.By test leakage machine to detection cavity inflation, according to the leakage cross-sectional area and height of normal assembly deduce maximum legal loss boundary, set as leakage upper limit.Inflation pressure monitoring after stabilization, when actual leakage exceeds leakage upper limit, it is judged that there is missing loading defect and NG signal is output, and other cylinders are tested for leakage in turn, and data is synchronously interacted to system.The present application overcomes the limitation of traditional differential pressure leakage relying on completely closed cavity, directly identifies missing loading defect by capturing the pressure drop difference caused by component loss, and realizes automatic quality interception.
